Body-mounted monitoring devices are worn on the skin of a user. In some embodiments, the monitoring devices are worn by the user for multiple days via an adhesive layer that couples to the monitoring device and the skin of the user. The adhesive layer may break down or start to fail over time. Thus, the monitoring device is removed from the user, the adhesive layer is removed from the monitoring device, a new adhesive layer is applied to the monitoring device, and the monitoring device is then reapplied to the skin of the user. Manual removal of the adhesive layer and subsequent alignment and application of the new adhesive layer is often difficult. It is also possible for the user to improperly orient the adhesive layer on the monitoring device. In some embodiments, the monitoring device is not worn continuously. In other embodiments, the monitoring device is worn continuously but is not operating continuously. In these instances, it is desirable to preserve the battery life of the monitoring device by selectively disabling the monitoring device.

A monitoring device is generally referred to by the reference numeral 5 and an adhesive applicator is generally referred to by the reference number 10 as illustrated in
As illustrated in
In an example embodiment, the housings 15a and 15b are elastomeric housings.
In some embodiments, the control system 17 includes a substrate 30, a thermal sensor 35, a microcontroller 40, and a power supply 45. In some implementations, the substrate 30 can be a circuit board or printed circuit board (PCB). Additional or fewer components are possible. For example, the control system 17 may include an accelerometer, a humidity sensor, or other biometric sensors that are in communication with the microcontroller 40. The thermal sensor 35 is in communication with the microcontroller 40 and the thermal contact 20. Generally, the microcontroller 40 includes a processor and a memory. The microcontroller 40 is configured for wireless communication with a remote device via a network. In an example embodiment, the network includes the Internet, one or more local area networks, a bluetooth low energy network, one or more wide area networks, one or more cellular networks, one or more wireless networks, one or more voice networks, one or more data networks, one or more communication systems, and/or any combination thereof.
In some embodiments, an opening 55 is formed in the adhesive layer 25. In some embodiments, the opening 55 has a diameter that is greater than the outer diameter of the thermal contact 20. However, in other embodiments, the diameter of the opening 55 is equal to or less than the outer diameter of the thermal contact 20. In some examples, the thermal contact 20 facilitates physical measurement of properties of the body of the wearer (e.g., of the skin at the external body surface). As shown, the thermal contact 20 is a circular, rounded contact configured to protrude from the lower housing 15b and to make electrical and/or thermal contact with the skin of the external body surface of the wearer. In some embodiments, the thermal contact 20 extends between about 0.05 cm and about 0.2 cm from the lower housing 15b. In some embodiments, the contact 20 is in electrical contact with the thermal sensor 35 such that a galvanic skin response (“GSR”) of the skin at the external body surface can be detected by the monitoring device 5. However, in other embodiments, the contact 20 is in thermal contact only with the thermal sensor 35. In some embodiments, the temperature sensor 35 is a thermal sensor, which may be a thermistor, a resistance temperature detector (“RTD”), a capacitance temperature sensor, a semiconductor device, or an infrared camera. Generally, the thermal contact 20 and the thermal sensor 35 are positioned and configured to continuously monitor and detect a temperature of the patient. In other embodiments, the thermal contact 20 and the thermal sensor 35 are positioned and configured to intermittently monitor the temperature of the patient. For example, the thermal contact 20 and the thermal sensor 35 may detect a temperature every 1 minute, every 30 seconds, every 5 seconds, every 1 second, or every 0.5 second. Regardless, the thermal contact 20 and the thermal sensor 35 monitor or detect a temperature of the patient. In some embodiments, the thermal contact 20 is a metal disc.
The adhesive layer 25 can be a double-sided adhesive layer having has one surface 25a that includes an adhesive configured to couple the adhesive layer 25 to the lower housing 15b and another opposing surface 25b that includes an adhesive configured to couple to the patient. In some embodiments, the adhesive on the surface 25a is different from the adhesive on the surface 25b. In some embodiments, the adhesive is selected to have material properties permitting it to be peeled from the patient's skin by pulling a corner or edge from the skin at an angle from the skin within a range from about 10 to 170 degrees without damaging the skin. In addition and in some embodiments, the adhesive can be removed without damaging the skin without the use of water, soap, solvent or other releasing material. In some embodiments, the adhesive is selected to have an adhesion to LDPE, 180 Degree peel of 15-50 oz/inch width, and more particularly, about 20-50 oz/inch width, and more particularly, about 30-40 oz/inch width, and even more particularly, about 35-37 oz/inch width. The adhesive may be a skin-friendly, rubber based adhesive. Further, the adhesive is configured so that in some embodiments, less than 10% of the adhesive remains on the skin as residue. In other embodiments, less than 5% of the adhesive remains on the skin as residue. In some embodiments, the adhesive layer 25 attaches the monitoring device 5 to the skin of the patient in a manner that also couples the thermal contact 20 to the skin of the patient.
In an example embodiment, the power source 45 is a battery or the like.
In some embodiments, the monitoring device 5 is configured to operate in a battery preservation mode. In some embodiments, the monitoring device 5 automatically enters battery preservation mode upon detection of a disabling event. However, in other embodiments, the user can instruct the monitoring device 5 to enter battery preservation mode. One example of the monitoring device 5 automatically entering the battery preservation mode upon detection of a disabling event includes the microcontroller 40 determining that the temperature detected by the thermal sensor 35 is below a minimum temperature. In some embodiments, the minimum temperature is a minimum temperature associated with the thermal sensor 35 being in contact with the skin of the user. Thus, the detected temperature being below the minimum temperature is an indication that the monitoring device 5 is not being coupled to the patient. When this occurs, the control system 17 transitions into a sleep or idle mode. In some embodiments, the monitoring device 5 includes an additional sensor, such as for example, a capacitive sensor, an accelerometer, and an audio sensor (or any combination thereof), with each being in communication with the microcontroller 40. For example, when the additional sensor is the capacitive sensor, the capacitive sensor is positioned to contact the skin of the user when the monitoring device 5 is coupled to the user. Upon determination, by the microcontroller 40 and based on the conditions detected by the capacitive sensor, that the capacitive sensor is no longer in contact with the user, the monitor 5 enters battery preservation mode (e.g. sleep or idle mode). However, when the additional sensor is the accelerometer and in some embodiments, the disabling event may be lack of movement (breathing movement) by the user over a period of time, thereby indicating that the monitoring device is not coupled to the user. In other embodiments and when the audio sensor is the additional sensor, the disabling event may be the absence of an audible heartbeat, or other audible marker emitted by the patient, that is detectable when the monitoring device is coupled to the user. The control system 17 may include a combination of sensors to improve the identification of a disabling event. In some instances, when in sleep or idle mode, the control system 17 periodically or intermittently reawakens or partially reawakens to determine if the temperature sensed by the thermal sensor 35 is equal to or greater than the minimum temperature. If so, then the control system 17 resumes normal operations. In other embodiments, and when the microcontroller 40 is wirelessly coupled to a second device via a mobile application and a network, the control system enters battery preservation mode upon receipt of an instruction from the second device via the mobile application and the network. In some embodiments, the remote device is a smart phone, tablet computer, personal digital assistant (PDA), or personal computing device (PCDs), or the like. In other embodiments, the user depresses or otherwise activates an on/off button that is in communication with the microcontroller 40. The input from the on/off button alternatively instructs the monitoring device 5 to enter and exit the battery preservation mode.
In an example embodiment, the monitoring device 5 entering the battery preservation mode preserves battery life. Thus, when the power supply 45 is a non-rechargeable battery, the ability to preserve battery life extends the design life of the monitoring device 5.
In an example embodiment and in reference to
In some embodiments, the liners 90 are composed of a material that prevents the adhesive layers 25 from sticking or adhering to the liners 90.
The device 5 and/or the applicator 10 can be altered in a variety of ways. For example, the springs 75 may be omitted and replaced with a variety of force generating elements. For example, the springs 75 may be replaced with Belleville washers, resilient arms, resilient buttons, air bag, etc. As illustrated in
At the step 205, the adhesive layer 25 is removed from the lower housing 15b of the monitoring device 5. In some example embodiments, removing the adhesive layer 25 is performed manually. That is, a user peels the adhesive layer 25 off of the lower housing 15b.
At the step 210, the uppermost adhesive liner 90 is removed from the adhesive applicator 10. For example and as illustrated in
At the step 215, the monitoring device 5 is aligned with the opening 85 of the applicator 10. Due to shape of the monitoring device 5 and the corresponding opening 85, there is generally only one alignment of the device 5 and the opening 85 that allows the monitoring device 5 to enter into the opening 85. Aligning the monitoring device 5 in the opening 85 also automatically aligns the thermal contact 20 into the opening 55 of the uppermost adhesive layer 25.
At the step 220, the uppermost adhesive layer 25 is coupled to the lower housing 15b. In some embodiments, and as illustrated in
At the step 225, the monitoring device 5 is removed from the applicator 10. During the step 225, the monitoring device 5, including the uppermost adhesive layer 25, is lifted from the applicator 10 to expose another uppermost adhesive liner 90.
Generally, the steps 205-225 are repeated as desired to remove a used adhesive layer and apply a new adhesive layer to the monitoring device.
In some embodiments, the step 205 is omitted and the new adhesive layer 25 is applied over an old adhesive layer 25 that remains on the device 5.
In some embodiments and during the step 205, the adhesive layer 25 is removed using an adhesive layer removal device 300. As illustrated in
In some embodiments, the device 5 moves relative to the device 300 in a direction that is opposite the direction 325. In some embodiments, the removal device 300 forms a portion of the adhesive applicator 10.
In some embodiments, use of the monitoring device 5 and the adhesive applicator 10 and/or the method 200 results in the adhesive layers 25 being properly applied to the monitor 5, thereby preventing misalignment of the layer 25 and the monitor 5, which reduces the reliability of the adhesion between the monitor 5 and the user. Misalignment of the adhesive layer 25 and the monitor 5 also increases the likelihood that debris can enter between the device 5 and the user, which reduces the reliability of the measurements and operation of the monitor 5. Generally, body-mountable sensing devices, such as the device 5, being disposable is desirable for user convenience. However, body-mountable sensing devices typically have high fixed cost due to the cost of the electronic components, required assembly, etc. Use life is typically not limited by the electronic capability or the power supply 45 (e.g., battery), but instead by the life of the adhesive layer 25. In some embodiments, providing the device 5 and method of using the device 5 together with the ability of the device 5 to enter into battery preservation mode, increases the number of uses of the device 5. This reduces the cost per use of the device 5 while avoiding significant burden to the user. The applicator 10 ensures that the surface 25a is coupled to the bottom of the housing 10b and the surface 25b of the layer 25 is exposed and available to be coupled to the skin of the patient. Moreover, the monitoring device 5 is configured to enter into a battery preservation mode between uses to extend the life of the power supply 45 (e.g., battery). In an example embodiment, the monitoring device 5 is a non-rechargeable monitor and is not intended to be recharged. Moreover, the ability to re-apply the adhesive layers 25 to the monitor 5 allows for better defined battery life, a potential to use a gentler adhesive, and re-application of the adhesive layer 25 in cases of mis-application. In some embodiments, the applicator 10 forms a portion of the packaging of the monitoring device 5.
