Adequate hydration is an important part of general well-being. In some contexts and for some people maintaining adequate hydration is more difficult. For example, patients in a care setting, e.g. bed-ridden, in a nursing home, or in a hospital, may find it difficult to remember to regularly take drinks and may have difficulty accessing water at regular intervals. For some patients, it may be useful to provide a reminder for the patient to take a drink at intermittent times.
GB2499829 provides a drinking aid for reminding a user to take a drink. However, the drinking aid is not particularly suitable for use in a care setting as it would be prone to trapping germs and would not allow adequate infection control. Also, the drinking aid is not adapted for a particular setting or for use by particular users.
Consequently, it is an object of the present disclosure to provide an improved drinking apparatus, system and method. The improved drinking apparatus, system and method may be more suitable for use in a care setting and provide more helpful methods of reminding a user to take a drink at intermittent times. They may in addition be more suitable for use in situations where infection control regimes are in operation.
Accordingly, in a first aspect the present disclosure provides a drinking apparatus comprising a receptacle and a sensor module;
Advantageously, the drinking apparatus of the present disclosure helps to prevent a user inadvertently exposing the sensor module of the drinking apparatus to a cleaning environment that may damage the sensor module. For example, the cleaning environment may be a source of water such as a running tap, a sink, or a dishwasher. A particular source of concern may be exposing the sensor module to the cleaning environment of a dishwasher due to the high temperatures, salt and cleaning agents typically used in such devices. The risk of inadvertent exposure to such cleaning environments is reduced by use of the alert system that detects when the drinking apparatus (including the coupled sensor module) is reorientated into the second, cleaning orientation. This is because typically a user wishing to clean the drinking apparatus will need to wholly or partially invert the receptacle. For example, in a dishwasher a user would wish to place the drinking apparatus in an upturned orientation in a rack of the dishwasher wherein the mouth of the receptacle is directed vertically, or nearly vertically downwards. Beneficially, as soon as the user inverts the drinking apparatus to place it in the rack the alert system will be triggered to generate the warning signal reminding the user to decouple the sensor module and thereafter only clean the receptacle in the dishwasher.
The term “warning signal” is used to refer to one or more signals (which may differ in their characteristics from one another) that are generated to be received by the user of the drinking apparatus. For example, the warning signal may be one or more of audio signal(s), visual signal(s) or tactile signal(s).
In this and other aspects of the present disclosure, the liquid for consumption may be, as non-limiting examples, water, a beverage or other preparation whether or not they also include solid elements, e.g. soups, tea, coffee, hot chocolate, etc. The term ‘liquid’ also encompass gels, fluids and pasty substances that may be consumed in a drinkable manner, for example milkshakes, high-fibre supplements, ice slushes, etc. In one preferred use, the drinking apparatus of the present disclosure finds application as a water container for drinking water. The drinking apparatus may form a hydration apparatus for a patient. The drinking apparatus is preferably sized for individual use and to be lifted by one hand. The user of the drinking apparatus may be a variety of classes of people. However, the present drinking apparatus provides particular benefits in a healthcare setting where a first class of user may be a patient. A second class of user may be a care-giver that has responsibility for ensuring adequate hydration of the patient and/or cleaning of the drinking apparatus. Both the patient and the care-giver may be users of the same drinking apparatus.
In the second, cleaning, orientation the mouth of the receptacle may be angled downwards to allow liquid to fully, or substantially fully, drain from the cavity out of the mouth of the receptacle. Advantageously, this may allow for all or substantially all of the liquid that might be in the cavity (or enter the cavity during cleaning) to drain under the action of gravity out of the cavity to allow for better cleaning and drying of the receptacle. For example, when the dispensing apparatus is cleaned in a dishwasher it is preferable to orientate the mouth of the receptacle to be angled downwards to prevent the pooling and retention of cleaning water in the cavity during the cleaning cycle of the dishwasher.
In the second, cleaning, orientation the receptacle may have been tilted away from the first, storage, orientation by greater than 90°, preferably greater than 100°, more preferably greater than 135°. For receptacles of differing shapes it may be necessary to tilt the receptacle by a differing angle to reach a suitable cleaning orientation in which the liquid can adequately drain from the mouth. This may depend on the shape of the receptacle, the angle of the side walls of the receptacle, etc. It may be preferred to select a detection angle for the alert system at which the warning signal is generated that is greater than a tilt angle that would be expected to be experienced during normal drinking from the receptacle. This would help reduce the likelihood of triggering the warning signal when drinking from the drinking apparatus. However, this is not essential, only preferred.
In the second, cleaning, orientation the drinking apparatus may be inverted, preferably so that the mouth of the receptacle is directed vertically, or nearly vertically downwards. This would be a typical orientation for the drinking apparatus when placed in an upper rack of a dishwasher (where the platens of the rack are typically angled at a small offset from horizontal to help prevent pooling of cleaning water on the bases of receptacles).
The alert system may be configured to generate the warning signal immediately on detection of the reorientation of the drinking apparatus into the second, cleaning, orientation. This may provide the most immediate warning to the user to remove the sensor module, for example before closing of a door of the dishwasher has taken place.
The alert system preferably comprises a sensor configured to detect reorientation of the drinking apparatus into the second, cleaning, orientation.
The sensor may comprise a tilt sensor. The sensor may comprises a ‘ball-in-can’ tilt sensor. For example, ‘ball-in-can’ sensor may comprises a cylindrical housing (can) provided with two spaced apart switch contacts at one end of the housing. Within the housing is provided one or more electrically-conductive balls that can move between one end of the housing away from the switch contacts to the other end of the housing where the ball(s) bridge between the switch contacts closing the circuit. Movement of the ball(s) within the can is triggered by tilting of the housing.
As an alternative to a tilt sensor the sensor may comprise a gyroscope or hall effect sensor.
More than one sensor may be used in combination to detect reorientation of the drinking apparatus.
The alert system may comprise one or more lights configured to generate the warning signal in the form of a visual alert. The one or more lights may comprise one or more light-emitting diodes (LEDs). The one or more lights may be located within an interior of the sensor module and may be configured to transmit light through a face of the sensor module. The visual alert may comprise one or more patterns of intermittent flashing or pulsing of the one or more lights.
The alert system may comprise a speaker configured to generate the warning signal in the form of an audible alert. The speaker may be located within an interior of the sensor module and may be configured to transmit sound waves via a face of the sensor module; and wherein optionally the speaker may be an exciter speaker. Advantageously, the use of an exciter speaker may avoid the need to include any apertures in the sensor module outermost surface since the sound waves are transmitted via the excitation of the surface of the sensor module and not via movement of air through apertures. The absence of such apertures in the sensor module helps to avoid the creation of cavities in the outer surface of the sensor module which might otherwise provide a location for breeding of germs.
Alternatively, a portion of a housing of the sensor module may be provided with an array of apertures for transmission of sound waves. A separate thin membrane may then be affixed to an exterior of the housing of the sensor module to cover the apertures. The membrane may be secured to the housing around the circumferential periphery only to allow the membrane to resonate freely against the housing when driven by sound waves produced by a speaker located within the interior of the sensor module. The membrane may be formed from a plastics material that may be flexible. Advantageously, the apertures may improve the transmission of the sound waves out of the sensor module while the membrane helps to prevent the creation of any cavities on the exterior of the sensor module which might otherwise provide a location for breeding of germs. Protrusions may be provided on the housing exterior to create a space between the membrane and a support surface which may provide space for the membrane to resonate freely.
The alert system may comprise a tactile signal generator. For example, the alert system may comprise a vibrator that causes vibration of the sensor module.
The alert system may comprise any combination of the above-described lights, speakers and/or tactile signal generators.
The sensor module and the receptacle may comprise complementary connection means to permit coupling and decoupling of the sensor module and the receptacle; optionally wherein the complementary connection means comprises screw threads.
The receptacle may comprise a recess which receives at least a portion of the sensor module on coupling of the sensor module to the receptacle.
A seal may be provided between the sensor module and the receptacle to hinder or prevent ingress of water there between.
At least a portion of the sensor module may be formed from a transparent or translucent material.
The sensor module may be coupled to any suitable portion of the receptacle. However, it may be particularly beneficial where the sensor module is coupled to the receptacle below the cavity. In this way the centre of gravity of the drinking apparatus may be lowered by locating the sensor module towards the bottom/base of the drinking apparatus. This may improve the stability of the drinking apparatus. In some embodiments the sensor module may form a base unit of the drinking apparatus. The drinking apparatus may be able to freely stand on the support surface with the base unit in contact with the support surface.
The sensor module may further comprise a reminder system to intermittently prompt a user to consume liquid from the receptacle. The reminder system may comprise one or more sensors configured to detect a drinking event associated with a user consuming liquid from the cavity. The one or more sensors configured to detect a drinking event associated with a user consuming liquid from the cavity may comprise a sensor configured to detect tilting of the receptacle away from the vertical; and preferably the sensor may be configured to detect tilting of the receptacle away from the vertical by greater than 15°, preferably greater than 30°. The sensor configured to detect tilting of the receptacle away from the vertical may comprise a tilt sensor. As an alternative to a tilt sensor the sensor may comprise a gyroscope or hall effect sensor.
The drinking apparatus may comprise the sensor configured to detect reorientation of the drinking apparatus into the second, cleaning, orientation and a separate one or more sensors configured to detect a drinking event associated with a user consuming liquid from the cavity. Advantageously, this may allow for the performance characteristics of each sensor to be adapted for the different requirements of detecting tilting associated with drinking and detecting a tilting (typically greater tilting) associated with inverting the drinking apparatus into the second, cleaning, orientation. For example, different designs of tilt sensor may be used for the different sensors.
The reminder system may further comprise:
The control interface may be configured to permit the user of the drinking apparatus to:
The reminder system may further comprise:
When the sensor module is coupled to the receptacle the control interface may be inaccessible by the user; and optionally the control interface may comprise a plurality of buttons for inputting user commands which may be inaccessible when the sensor module is coupled to the receptacle. Advantageously, this helps to prevent accidental activation of the control interface when a user is drinking from the drinking apparatus. In addition, where the drinking apparatus is for a patient who is under the supervision of a care-giver, the control interface may be operated by the care-giver and the patient may be hindered from accidentally or deliberately altering the setting of the drinking apparatus during use.
The receptacle may comprise a recess which may receive at least the control interface of the sensor module on coupling of the sensor module to the receptacle so as to render the control interface inaccessible to the user while the sensor module remains coupled to the receptacle.
The power source may comprise one or more batteries housed in a battery compartment, and when the sensor module is coupled to the receptacle the battery compartment may be inaccessible by the user.
The drinking apparatus may further comprise an ambient light sensor for detecting an ambient light level around the drinking apparatus when on the support surface. The ambient light sensor may be housed within an interior of the sensor module and may be configured to detect the ambient light level by detecting signals transmitted through a face of the sensor module.
Advantageously, the one or more sensors configured to detect a drinking event and the ambient light sensor do not require any apertures in the sensor module to function. This may help to reduce the number of cavities in the sensor module's outer surface that could provide a location for retention and growth of germs. It may also assist in allowing the sensor module to be configured as preferably splash-proof and/or water-resistant.
The controller may be configured to provide a night-time mode in which generation of the user alert is prevented whenever the ambient light level is below a predetermined level as detected by the ambient light sensor. Advantageously, this may help to prevent disturbance of the user during periods of sleep, e.g. at night, when drinking is not required. In the night-time mode the controller may be configured to activate the one or more lights when the ambient light level is below a predetermined level as detected by the ambient light sensor to thereby provide illumination for the user to locate the drinking apparatus. Advantageously, this may help a user to locate the drinking apparatus at night if the user wakes and wishes to take a drink. In the night-time mode the one or more lights may be activated in a mode pre-programmed to be one of: constant illumination, pulsing illumination or flashing illumination.
The drinking apparatus may further comprise a microphone located within an interior of the sensor module.
The controller may be configured to use one or more pre-recorded default audio alerts in the eventuality that the one or more audio messages are not recorded or selected. The controller may be configured to use the one or more audio messages sequentially if no drinking event is detected. The control interface may be configured to permit the user of the drinking apparatus to select a volume of the one or more audio alerts. The controller may be configured to repeat each audio alert at an increased volume. The one or more predetermined time intervals may include 20 minutes, 40 minutes and 60 minutes. The controller may be configured to reset the timer and restart measurement of the one or more predetermined time intervals whenever a drinking event is detected. The controller may be configured to interrupt the user alert, if being generated, whenever a drinking event is detected.
An interior face of the receptacle may comprise one or more filling-level markings, preferably annular rings.
The drinking apparatus may further comprise a lid that is detachably coupled to an open mouth of the receptacle.
In the present disclosure there is also provided a drinking system comprising a drinking apparatus as described above and further comprising a second receptacle which can be detachably coupled to said sensor module in place of the receptacle. The second receptacle may have a different shape and configuration to the receptacle. For example, one of the receptacles may be configured as a tumbler (not having a projecting handle) and another of the receptacles may be configured as a mug (having a projecting handle). An optional lid may also be provided as part of the drinking system. The lid may be a disposable part of the drinking system.
The present disclosure also relates to the sensor module of the drinking apparatus as described above and in the other aspects below. The present disclosure also relates to the receptacle of the drinking apparatus as described above and in the other aspects below.
The present disclosure also relates to a method of preventing damage to a drinking apparatus, wherein the drinking apparatus is as described above in the first aspect, the method comprising the steps of:
The method may comprise using the alert system to detect when the mouth of the receptacle has been angled downwards to allow liquid to fully, or substantially fully, drain from the cavity out of the mouth of the receptacle, and then generating the warning signal. The method may comprise using the alert system to detect when the receptacle has been tilted away from the first, storage, orientation by greater than 90°, preferably greater than 100°, more preferably greater than 135°, and then generating the warning signal. The method may comprise using the alert system to detect when the drinking apparatus is inverted, preferably so that the mouth of the receptacle is directed vertically, or nearly vertically downwards, and then generating the warning signal. The method may comprise generating the warning signal immediately on detection of the reorientation of the drinking apparatus into the second, cleaning, orientation.
A particular advantage of the drinking apparatus of all of the aspects of the present disclosure is that it may form a modular system that can be adapted for different users' needs. The modular system is formed by the constituent parts of one or more configurations of receptacle, a sensor module and optionally a lid. For example, at a simplest level the system provides a receptacle that, while adapted to be coupled with a sensor module, is able to be used as a standalone receptacle for the consumption of a liquid, e.g. water. This may be appropriate for a user (e.g. a patient) who is able to reliably remember to consume liquid at regular intervals. If the user has good dexterity then the receptacle may be configured as a tumbler without a handle. If a more secure grip by the user is required then a receptacle configured as a mug with a handle may be used. At the next level the system provides the option of a lid that can be received on the receptacle. The lid may be provided with features such as a mouth port and a straw hole, to assist users that may have difficult holding a receptacle steady. At a further level the system allows for the addition of the sensor module for users that require prompting to consume liquid at regular intervals.
In a second aspect of the present disclosure there is provided a drinking apparatus comprising a receptacle and a sensor module;
As noted above, advantageously, this helps to prevent accidental activation of the control interface when a user is drinking from the drinking apparatus. In addition, where the drinking apparatus is for a patient who is under the supervision of a care-giver, the control interface may be operated by the care-giver and the patient may be hindered from accidentally or deliberately altering the setting of the drinking apparatus during use.
The control interface may comprise one or more buttons for inputting user commands which are inaccessible when the sensor module is coupled to the receptacle.
The receptacle may comprise a recess and when the sensor module is coupled to the receptacle the control interface may be wholly located within said recess.
The sensor module and the receptacle may comprise complementary connection means to permit coupling and decoupling of the sensor module and the receptacle; optionally wherein the complementary connection means comprises screw threads.
The sensor module may further comprise:
The control interface may be configured to permit the user of the drinking apparatus to operate functions of the drinking apparatus including one or more of:
In a third aspect of the present disclosure there is provided a drinking apparatus comprising a receptacle and a sensor module;
As noted above, advantageously, this may help to prevent disturbance of the user during periods of sleep, e.g. at night, when drinking is not required. The ambient light sensor may be housed within an interior of the sensor module and may be configured to detect the ambient light level by detecting signals transmitted through a face of the sensor module.
The reminder system may comprise:
The controller may be configured to provide a night-time mode in which generation of the user alert is prevented whenever the ambient light level is below a predetermined level as detected by the ambient light sensor. In the night-time mode the controller may be configured to activate the one or more lights when the ambient light level is below a predetermined level as detected by the ambient light sensor to thereby provide illumination for the user to locate the drinking apparatus. In the night-time mode the one or more lights may be activated in a mode pre-programmed to be one of: constant illumination, pulsing illumination or flashing illumination. The ambient light sensor may be a phototransistor.
The sensor module may further comprise:
The control interface may be configured to permit the user of the drinking apparatus to operate functions of the drinking apparatus including one or more of:
In a fourth aspect the present disclosure provides a drinking apparatus comprising a receptacle and a sensor module;
As in the above aspects, the user of the drinking apparatus may be a variety of classes of people. However, the present drinking apparatus provides particular benefits in a healthcare setting where a first class of user is a patient. A second class of user may be a care-giver that has responsibility for ensuring adequate hydration of the patient. Both the patient and the care-giver may be users of the same drinking apparatus.
The term “user alert” is used to refer to one or more alerts (which may differ in their characteristics from one another) that are generated to be received by the one or more users of the drinking apparatus. Different types of alert may be intended to be received and prompt action by different classes of user of the drinking apparatus. For example, one or more audio alerts may be intended to prompt action by the patient who is normally near the drinking apparatus and is thereby prompted to drink from the drinking apparatus when the one or more audio alerts are heard. For example, one or more visual alerts may be intended to prompt action by the care-giver (nurse, doctor, etc.) who may be further away from the drinking apparatus or only in the vicinity of the drinking apparatus periodically, e.g. when conducting rounds in a hospital ward setting.
Advantageously, the drinking apparatus of the present disclosure provides an improved means for prompting hydration of a user by allowing a combination of audio and visual alerts to be presented. Consequently different alerts may be targeted at different users (visual alerts detectable by a care-giver from long range) and audio alerts (which are localised for the patient so as not to disturb other patients nearby). Further, the audio alerts may be personalised, for example, by using the user's name, the voice of a family member, etc. which may improve the likelihood of the user responding positively to the instruction. Personised messages also reduce the likelihood of confusing alerts produced by different drinking apparatus that may be present in the same location.
The ability to use a plurality of audio messages (default or personalised) is advantageous compared to repetition of a single message in that it improves the effectiveness of the audio alerts. This is because the variety in the content of the messages makes it more likely that the user will take note and follow the prompting of the message. By contrast a single repeated message may actually aggravate a user making it less likely that a drink will be consumed when prompted. The present drinking apparatus also has the advantage of being able to refresh the personalised messages whenever needed so as to provide even more variety in the audio alerts.
The sensor module may form a base unit of the drinking apparatus which is coupled below the cavity such that in the first orientation the sensor module contacts the support surface.
When the sensor module is coupled to the receptacle the control interface may be inaccessible by the user; and optionally the control interface may comprise a plurality of buttons for inputting user commands which may be inaccessible when the sensor module is coupled to the receptacle.
The control interface may be configured to provide voice prompt feedback to the user.
The power source may comprise one or more batteries housed in a battery compartment, and when the sensor module is coupled to the receptacle the battery compartment may be inaccessible by the user.
The sensor module and the receptacle may comprise complementary connection means to permit coupling and decoupling of the sensor module and the receptacle; optionally wherein the complementary connection means comprises screw threads.
The receptacle may comprise a recess which receives at least a portion of the sensor module on coupling of the sensor module to the receptacle.
An annular seal may be provided between the sensor module and the receptacle to hinder or prevent ingress of water there between.
The tilt sensor may comprise a tilt switch and/or a gyroscope.
The drinking apparatus may further comprise an ambient light sensor for detecting an ambient light level around the drinking apparatus when on the support surface. The ambient light sensor may be housed within an interior of the sensor module and may be configured to detect the ambient light level by detecting signals transmitted through a face of the sensor module. The controller may be configured to provide a night-time mode in which generation of the user alert is prevented whenever the ambient light level is below a predetermined level as detected by the ambient light sensor. In the night-time mode the controller may be configured to activate the one or more lights when the ambient light level is below a predetermined level as detected by the ambient light sensor to thereby provide illumination for the user to locate the drinking apparatus. In the night-time mode the one or more lights may be activated in a mode pre-programmed to be one of: constant illumination, pulsing illumination or flashing illumination.
The sensor module may be at least splash-proof.
The audio recorder may comprise a microphone located within an interior of the sensor module.
The speaker may be located within an interior of the sensor module and may be configured to transmit sound waves via a face of the sensor module; and wherein optionally the speaker is an exciter speaker as described above in a previous aspect. Alternatively, the sensor module may be provided with an array of apertures for transmission of sound wave which are sealed by a membrane configured to be able to resonate as described above in a previous aspect.
The one or more lights may comprise one or more light-emitting diodes (LEDs). The one or more lights may be located within an interior of the sensor module and may be configured to transmit light through a face of the sensor module. The one or more visual alerts may comprise one or more patterns of intermittent flashing or pulsing of the one or more lights.
The controller may be configured to use one or more pre-recorded default audio alerts in the eventuality that the one or more audio messages are not recorded or selected. The control interface may be configured to permit the user of the drinking apparatus to select a volume of the one or more audio alerts. The controller may be configured to use the one or more audio messages sequentially if no tilting event is detected. The controller may be configured to repeat each audio alert at an increased volume. The one or more predetermined time intervals may include 20 minutes, 40 minutes and 60 minutes. The controller may be configured to reset the timer and restart measurement of the one or more predetermined time intervals whenever a tilting event is detected. The controller may be configured to interrupt the user alert, if being generated, whenever a tilting event is detected.
An interior face of the receptacle may comprise one or more filling-level markings, preferably annular rings.
The drinking apparatus may further comprise a lid that is detachably coupled to an open mouth of the receptacle. The lid may comprise a mouth port and/or a straw port.
The sensor module may be reusable and the receptacle may be disposable.
This aspect also provides a method of reminding a user to take a drink at intermittent times, comprising:
a) providing a drinking apparatus comprising a receptacle and a sensor module;
b) measuring one or more predetermined time intervals;
c) detecting a tilting event associated with a user consuming liquid from the cavity;
d) generating a user alert if no tilting event is detected within a selected predetermined time interval;
wherein the user alert is selected to be one or more visual alerts and/or one or more audio alerts; wherein said one or more audio alerts are one or more audio messages which have been recorded by a user of the apparatus.
In a fifth aspect of the present disclosure there is provided a drinking system comprising a drinking apparatus and an external controller;
Advantageously, the drinking system permits one or more of the functions of the drinking apparatus to be programmed remote from the drinking apparatus.
The external controller may be a dedicated controller, for example a remote control, or a program or application running on an external device, for example a desktop computer, portable tablet, mobile phone, etc.
The signals between the external controller and the receiver of the sensor module may be any suitable signals, for example, infra-red, visible light, wi-fi, GSM, etc. The communication may be one way from the external controller to the receiver. Alternatively, the communication may comprise two-way communication of signals between the external controller and the receiver (in which case both the external controller and the receiver may function as transceivers).
The external controller may include means for recording one or more audio messages by the external controller which may then be transmitted to the receiver of the sensor module and stored as the one or more audio alerts. The external controller may include means for generating one or more audio alerts and/or one or more visual alerts as the user alert. A first external controller may be provided that is configured to program operation of the sensor module and a second external controller may be provided that is configured to generate the user alert.

The main PCB 54 may have mounted on it a first tilt sensor 85, shown schematically in
Where the main PCB 54 is mounted laterally within the sensor module 4 (so that it will be orientated horizontally when the drinking apparatus 1 is stood on a horizontal support surface) the first tilt sensor 85 may be orientated vertically with the switch contacts 86 uppermost—so that the first tilt sensor 85 is in an open state when the drinking apparatus is stood on a support surface on its sensor module 4. Use of the first tilt sensor 85 will be described below.
The main PCB 54 may, in addition, have mounted on it a second tilt sensor 95, shown schematically in
Where the main PCB 54 is mounted laterally within the sensor module 4 the second tilt sensor 95 may be orientated vertically with the dish of the dished platen 96 pointing upwards—so that the ball 98 rests in the dish when the drinking apparatus is stood on a support surface on its sensor module 4 so that the second tilt sensor 95 is in an open state. Use of the second tilt sensor 95 will be described below.

The LEDs 42, 82, the first tilt sensor 85, the second tilt sensor 95 and the ambient light sensor 55 may all be housed within an interior of the sensor module 4 and not provided on an exterior face of the sensor module 4.
As shown in
The drinking apparatus 1 may make use of the features described above to provide a reminder system to intermittently prompt a user to consume liquid from the receptacle 2. In particular, the reminder system may use the second tilt sensor 95 to detect a drinking event associated with a user consuming liquid from the cavity 14 and may do so by detecting tilting of the drinking apparatus 1.
In use, the drinking apparatus 1 may function to generate a user alert if no tilting event is detected by the second tilt sensor 95 within one or more pre-determined time intervals as measured by the timer of the controller. The term “tilting event” is used to refer to a movement of the drinking apparatus 1 that is sufficient in extent for the second tilt sensor 95 to reach its switching angle and therefore for the tilt sensor to change from an open state to a closed state (or vice versa). If desired the controller may be configured so that only a tilting event lasting for a minimum duration is used to reset the timer and hence prevent (or halt) a user alert. For example, a minimum time interval of 2 or 3 seconds may be chosen. The term “user alert” is used to refer to one or more alerts (which may differ in their characteristics from one another) that are generated to be received by one or more users of the drinking apparatus 1. Different types of alert may be intended to be received and prompt action by different classes of user of the drinking apparatus 1. For example, one or more audio alerts may be intended to prompt action by a patient who is normally near the drinking apparatus 1 and is thereby prompted to drink from the drinking apparatus 1 when the one or more audio alerts are heard. For example, one or more visual alerts may be intended to prompt action by a care-giver who may be further away from the drinking apparatus 1 or only in the vicinity of the drinking apparatus 1 periodically.
Thus, the user alert may comprise one or more visual alerts and/or one or more audio alerts as will be described below. Different time intervals may be set for triggering different user alerts. For example a first time interval may be set for triggering the one or more visual alerts and a second time interval may be set for triggering the one or more audio alerts. For example, the one or more audio alerts may be triggered after 20 minutes and the one or more visual alerts may be triggered after 60 minutes.
Successive user alerts may be generated after the expiry of each successive pre-determined time interval if a tilting event is still not detected. For example, the pre-determined time interval for the one or more audio alerts may be selected as 20 minutes and one or more audio alerts would then be generated every 20 minutes until a tilting event was detected. Likewise, the pre-determined time interval for the one or more visual alerts may be selected as 60 minutes and one or more visual alerts would then be generated every 60 minutes until a tilting event was detected. In an alternative option, the one or more visual alerts once triggered may remain active until a tilting event is detected. Thus, in this configuration, the one or more visual alerts would not be repeated (although accompanying audio alerts may still be triggered). This arrangement may be preferred for alerting a care-giver who is only periodically near the drinking apparatus 1.
The type of user alert and the length of the time interval for each type of user alert may be set by the user by operation of the control interface 43. The control interface 43 may comprise the plurality of interface buttons 44 alone but preferably also includes voice prompts that are generated by the controller and transmitted via the speaker 50 in response to activation of the interface buttons 44. The voice prompts may confirm the current selection to the user. The interface buttons 44 may be configured to carry out a first action when given a short press (for example less than 1 second) and a second action when given a long press (for example 3 or 4 seconds or more).
Importantly, the control interface 43 may only be accessed and operated when the sensor module 4 is decoupled from the receptacle 2. Advantageously, this helps to prevent accidental activation of the control interface 43 when a user is drinking from the drinking apparatus 1. In addition, where the drinking apparatus 1 is for a patient who is under the supervision of a care-giver, the control interface 43 may be operated by the care-giver and the patient may be hindered from accidentally or deliberately altering the setting of the drinking apparatus 1 during use.
To use the drinking apparatus 1 the sensor module 4 must first be switched on. With the sensor module 4 decoupled from the receptacle 2, the user (or care-giver) may switch on the sensor module 4 by a long press on the red button 45. The device notification light in the form of the one or more red LEDs 82 may briefly flash once when the sensor module 4 is switched on, flash intermittently while the sensor module 4 is on, remain illuminated whenever the sensor module 4 is on, or provide a steady slow pulsing light whenever the sensor module 4 is on. In addition, when the sensor module 4 is first switched on it may provide an audio summary of the current settings of the module using the speaker 50.
The sensor module 4 may then be coupled to the receptacle 2 by means of the complementary connection means. A liquid for consumption, for example water or a isotonic beverage, is poured into the cavity 14. The volume marking rings 15 may be used to assist in filling a desired volume of liquid into the receptacle 2 which may be helpful if the beverage is being made up as a solution of a powdered component dissolved in a carrier fluid such as water.
If desired, the lid 3 may be fitted to the open mouth 12 and a straw inserted into the straw port 22 if required.
The drinking apparatus 1 is stood on a support surface, e.g. a bedside cabinet, when not being used. In this storage orientation the second tilt sensor 95 is not triggered. Typically the dished platen 96 will be horizontal, i.e. parallel to the support surface. The generation of user alerts is associated with detecting tilting of the drinking apparatus 1 away from the vertical. Tilting of the drinking apparatus 1 to at least the switching angle, e.g. 15° or 30°, will cause the second tilt sensor 95 to be closed and hence triggered (optionally after a minimum time threshold is exceeded). The triggering of the second tilt sensor 95 is detected by the controller which registers this as a tilting event.
A user alert is generated by the controller if no tilting event is detected by the second tilt sensor 95 within the one or more pre-determined time intervals as measured by the timer. (As noted above, the user alert may include either or both audio and visual alerts which may be set to be triggered after the same or different time intervals). If a tilting event occurs the counting of all measured time intervals by the timer is reset and timing recommences when the second tilt sensor 95 detects that the drinking apparatus 1 has been returned to vertical. Any user alert being generated may be interrupted if a tilting event occurs during the user alert.
A first type of user alert may be one or more visual alerts making use of the blue LEDs 42. Optionally the eight LEDs 42 may flash sequentially. They may flash in pairs sequentially. The two LEDs of each pair may be on opposed sides of the cup-shaped body 30. The order of illumination of the pairs of LEDs may be configured to create the impression of a moving set of lights. In one example a first pair of LEDs may be illuminated followed by a non-adjacent pair of LEDs, followed by an adjacent or non-adjacent pair of LEDs. For example, in the case of eight LEDs 42 which are equi-spaced (as shown in the example of
This visual user alert may be programmed (when the sensor module 4 is decoupled) by short presses of the yellow button 47. In one example successive short presses of the yellow button 47 cycles the time interval for the one or more visual alerts between settings of 20 minutes, 40 minutes, 60 minutes and ‘off’ (when ‘off’ no visual alerts would be generated).
A second type of user alert may be one or more audio alerts making use of the speaker 50. This user alert may be programmed (when the sensor module 4 is decoupled) by short presses of the green button 46. In one example successive short presses of the green button 46 cycles the time interval for the one or more audio alerts between settings of 20 minutes, 40 minutes, 60 minutes and ‘off’ (when ‘off’ no audio alerts would be generated).
The first and/or second types of user alerts may be selected in any desired combination. In one example the visual alerts may be selected to generate after 20 minutes and the audio alerts may be switched off. In a second example the visual alerts may be selected to generate after 40 minutes and the audio alerts may selected to generate after 40 minutes as well. In a third example the audio alerts may be selected to generate after 20 minutes and the visual alerts may selected to generate after 60 minutes. Other combinations are of course possible as will be apparent to the reader.
The one or more visual alerts may be intermittent illumination (e.g. flashing) of the LEDs 42 or constant illumination of those LEDs or a steady slow pulsing light. The one or more visual alerts may be generated for a fixed period only or may be generated until a tilting event is detected. The one or more visual alerts may be visible to the user through the side wall 31 and radiused section 38 of the sensor module 4.
The one or more audio alerts may be any suitable audio signal. However, preferably the audio alerts are spoken messages conveying a command message, for example, “Have a drink”, “Time to drink”, etc. Preferably, a plurality of spoken messages may be provided which are generated cyclically.
The controller may be provided with one or more default spoken messages which are pre-recorded for use as the audio alerts, for example messages DEFAULT 1, DEFAULT 2 and DEFAULT 3. Message DEFAULT 1 would be played after expiry of a first pre-determined time interval, in this example 20 minutes, if no tilting event is detected. After a further 20 minutes message DEFAULT 2 would be played back if a tilting event is still not detected. After a further 20 minutes message DEFAULT 3 would be played back if a tilting event is still not detected. Thereafter, the pattern would repeat with messages DEFAULT 1, DEFAULT 2 and DEFAULT 3 be played cyclically until a tilting event was detected.
Preferably, the sensor module 4 has the ability of allowing a user (e.g. a care-giver) to record one or more personalised messages, for example three messages, PERSONAL 1, PERSONAL 2 and PERSONAL 3 using the microphone 51. The personalised messages may then be used cyclically as the audio alerts instead of the default spoken messages in the same manner as just described for the default messages. Personalised messages may be recorded by a long press of the blue button 48. The user may check the content of the stored default or personalised messages by use of short presses of the blue button 48 which will sequentially playback the stored messages.
Therefore, for example three default spoken messages (DEFAULT 1, DEFAULT 2 and DEFAULT 3) may be stored in the memory of the controller and in addition three personalised messages (PERSONAL 1, PERSONAL 2 and PERSONAL 3) may be stored. If drinking apparatus 1 is reset to clear the personalised messages, the default spoken messages will still be stored and will be used as the audio alerts unless and until new personalised messages are recorded.
Each time an audio alert is generated it may optionally be repeated after a short delay, e.g. 5 to 7 seconds, to increase the likelihood that the user will notice the audio alert. The volume of the repeat may be set higher than for the original playback. The volume of each repeat may increase up to a set maximum volume.
The volume of the audio alerts may be set by use of the control interface 43. The volume may be programmed by use of short presses of the red button 45.
The drinking apparatus 1 may be provided with a night-time mode of operation in which generation of the user alert is prevented whenever the ambient light level is below a predetermined level as detected by the ambient light sensor 55. If desired the controller may be configured that only a change in ambient illumination lasting for a minimum duration is used to trigger starting or stopping of the night time mode. When the night-time mode is operational, the controller may be configured to activate the one or more red LEDs 82 to act as location lights to assist a user in finding the drinking apparatus in the dark. However, it is preferred that the level of illumination is kept low so as not to disturb a user's sleep. Therefore, preferably the maximum intensity of the location lights is kept to a predetermined level by configuration of the number or power of the LEDs used for the location lights. For example, this may be achieved by using only one of the red LEDs 82. In the night-time mode the one or more red LEDs 82 may be activated in a mode pre-programmed to be one of: constant illumination, pulsing illumination or flashing illumination. The night-time mode of operation may be switched on and off by long presses of the yellow button 47.
The LEDs 42 may also be used to provide a low battery level warning wherein they flash rapidly to alert a user that the batteries need replacing.
The drinking apparatus 1 may make use of the features described above to provide an alert system which is configured to generate a warning signal on detection of a reorientation of the drinking apparatus 1 into a cleaning orientation to warn a user against cleaning the drinking apparatus 1 while the sensor module 4 remains coupled to the receptacle 2. Such reorientation of the drinking apparatus 1 may be considered an inversion event. The term “inversion event” is used to refer to a movement of the drinking apparatus 1 that is sufficient in extent for the first tilt sensor 85 to reach its switching angle and therefore for the tilt sensor to change from an open state to a closed state (or vice versa).
The alert system may help to prevent a user exposing the sensor module 4 to a cleaning environment that may cause damage to the sensor module 4.
The alert system may be provided instead of the reminder system described above. However, preferably the alert system is provided as well as the reminder system. The alert system may make use of some or all of the same components as used by the reminder system. However, it is preferred that the alert system makes use of a dedicated sensor, for example the first tilt sensor 85 that is separate from the second tilt sensor 95. This allows the functional characteristics of both sensors to be optimised for their differing roles.
The alert system may be triggered when the mouth 12 of the receptacle 2 is angled downwards. In use the alert system may be triggered when the receptacle 2 has been tilted away from the a orientation by greater than 90°, preferably greater than 100°, more preferably greater than 135°. At the chosen angle the first tilt sensor 85 will be triggered which is detected by the controller of the sensor module and registered as the inversion event. Preferably in an inversion event the mouth 12 is angled downwards, which will typically mean directed below the horizontal plane. Preferably the degree of tilting in an inversion event is significantly greater than the degree of tilting in a tilting event. In this way the majority of tilting events will not be detected as an inversion event. However, this is not to exclude that an event may be both a tilting event and an inversion event.
In use, when the controller detects that an inversion event has occurred the blue LEDs 42 are triggered to generate a visual warning signal. Preferably the visual alert is generated immediately upon detection of the inversion event. The visual warning signal may be, for example, all eight LEDs 42 flashing rapidly together. Preferably the visual warning signal for an inversion event is different to the visual alert triggered to prompt a user to consume a drink. Other alerts (audio, tactile) may be used as well or instead of a visual warning signal.
It will be noted that the alert system is configured to produce an alert on detection of a movement of the drinking apparatus 1 occurring whereas the reminder system is configured to produce an alert when a movement of the drinking apparatus has not occurred.
Cleaning of the drinking apparatus 1 in a dishwasher is an example of where an inversion event may occur. A user may be tempted to place the whole drinking apparatus 1 into the rack of a dishwasher. To do so the drinking apparatus 1 would be inverted (i.e. tilted or rotated) to point the mouth 12 downwards to allow for drainage of cleaning water from the cavity 14. Racks in dishwashers are typically angled slightly away from the horizontal. Thus placing the drinking apparatus 1 upside down in the rack would involve tilting the drinking apparatus through approximately 155 to 175°. Since this degree of tilting exceeds the switching angle of the first tilt sensor 85 an inversion event would be detected and the LEDs 42 would flash a warning alert to the user to prompt them to stop and remove the sensor module 4. Thereafter the receptacle 2 may be cleaned in the dishwasher on its own.
In the second embodiment the receptacle 2 takes the form of a handled cup and comprises a handle 60 which projects from the side wall 10 of the receptacle 2. Advantageously, the handle 60 may assist a user who has limited manual dexterity to grip the drinking apparatus 1. In particular, the handle 60 may be in a general L-shape providing an opening 61 facing towards the bottom to allow easy access for the fingers. The handle 60 may also be provided with a large grip area and a stabilising recess 62 on an upper part that may receive a user's thumb.
The present disclosure extends to provide a drinking system which may comprise a plurality of receptacles 2 and a single sensor module 4 that can be used with each receptacle 2. For example a receptacle 2 of the first embodiment (without a handle) and a receptacle 2 of the second embodiment (with a handle 60) may be supplied with a single sensor module 4 that is detachably couplable to either receptacle 2. This allows a user a choice of type of receptacle 2 to use. It may also allow the receptacle to form a disposable part of the drinking system and the sensor module 4 to form a reusable part of the drinking system. The drinking system may also comprise the optional lid 3. The lid 3 may form a disposable part of the drinking system.
In the third embodiment, the drinking apparatus 1 is configured to interact wirelessly with one or more external controllers 70 to permit programming of the operation of the sensor module 4 and/or the generation of a user alert remote from the drinking apparatus. Thus, the drinking apparatus 1 and the external controller(s) 70 together form a drinking system.
The drinking apparatus 1 may be as described above in any of the previous embodiments except for the following modifications of the sensor module 4. The main modification is that the sensor module 4 is provided with a receiver 71 for receiving signals from at least one external controller 70. The sensor module 4 may not be provided with a microphone in this embodiment.
The external controller 70 comprises means for sending signals to receiver 71 of the sensor module 4. This means may be a transmitter of known type. The signals 72 from the external controller 70 to the receiver 71 of the sensor module 4 may be any suitable signals, for example, infra-red, visible light, wi-fi, GSM, etc.
The communication may be one way from the external controller 70 to the receiver 71. Alternatively, the communication may comprise two-way communication of signals 72, 73 between the external controller 70 and the receiver 71 (in which case both the external controller 70 and the receiver 71 may function as transceivers). Further the receiver 71 may receive signals from one external controller 70 and send signals to another external controller 70.
The external controller 70 may be a dedicated controller, for example a remote control, or a program or application running on an external device, for example a desktop computer, portable tablet, mobile phone, etc.
The external controller 70 may be configured to permit operation of functions of the drinking apparatus 1 including one or more of:
Advantageously, the drinking system permits one or more of the functions of the drinking apparatus 1 to be programmed remote from the drinking apparatus 1.
The external controller 70 may include means 74 (e.g. a microphone) for recording one or more audio messages by the external controller 70 which may then be transmitted to the receiver 71 of the sensor module 4 and stored as the one or more audio alerts.
In addition, or alternatively, the external controller 70 may include means (e.g. a speaker and or a light) to generate a user alert if a tilting event is not detected within the measured time interval. The user alert generated at the external controller 70 may be in addition or instead of the user alert generated at the sensor module 4. This function may be useful in a care setting where the external controller 70 is located at, for example, a nursing station on a ward.
The external controller 70 may include a user interface 75 to permit a user to receive information (including but not limited to user alerts) and select commands.
The same external controller 70 may be used to generate user alerts as is used to program operation of the sensor module 4. Alternatively, a first external controller 70 may be provided that is dedicated for programming operation of the sensor module 4. A second external controller 70 may be provided by which the user alerts are generated. This may be advantageous in a ward setting where the sensor module 4 may be programmed by a care-giver stationed near the patient but the user alerts are generated at a centralised nursing station.
