Health care monitoring has become an important part of the practice of medicine. When patients have been diagnosed with a generally treatable condition such as high blood pressure, diabetes and certain breathing disorders, health care professionals often request that patients monitor their conditions in their home. Providing health records of such medical parameters as blood pressure, glucose levels and oxygen saturation can be an important aid to helping help care professionals treat their patients.
Medical devices like blood pressure monitors, glucose monitors and oxygen saturation monitors are commonly available for a remote environment. These medical devices are typically available as separate units. Many of these medical devices may be difficult to use, particularly for patients that are visually impaired, mechanically challenged or generally averse to technology.
Embodiments of the disclosure are directed to a health care medical device. The health care medical device comprises one or more medical sensor devices, an assembly that houses the one or more medical sensor devices and a mobile electronic computing device with a display. The mobile electronic computing device is secured to the assembly and medical data from the one or more medical sensor devices is transmitted to the mobile electronic computing device.
In another aspect, a method of monitoring medical parameters of a patient using a health care medical device comprises placing one or more medical sensors from the health care medical device on the patient. Data is received from the one or more medical sensors. The received data is processed into medical parameters associated with the one or more medical sensors. Medical data based on the medical parameters is sent parameters to a mobile electronic computing device that is part of the health care medical device. The medical data is displayed on a display screen of the mobile electronic computing device. A wireless connection is made from the mobile electronic computing device to an Internet-based storage system. The medical data is sent to the Internet-based storage system.
In yet another aspect, a health care medical device comprises one or more medical sensor devices, a tablet computer and an assembly that houses the one or more medical sensor devices and the tablet computer. The medical sensor devices include one or more of a blood pressure sensor, oxygen saturation sensor, thermometer and glucose meter. The assembly encloses the back and at least a part of four sides of the tablet computer. The tablet computer provides visual and oral prompts to a user during operation of the health care medical device and the tablet computer transmits medical data from the one or more medical sensor devices to an Internet-based storage system.
The details of one or more techniques are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of these techniques will be apparent from the description, drawings, and claims.
The present disclosure is directed to a health care system that integrates a plurality of medical sensor devices in a single unit. The health care system is designed so that it is easy to use. In some examples, visual and oral prompts are included to provide instructions and reminders to patients. A compute engine such as a tablet computer or smart telephone controls the visual and oral prompts, receives and displays medical data from the medical sensor devices and transmits the medical data to an Internet-based storage system.
In one example, the health care system includes a base unit and the compute engine. The base unit includes medical sensor devices such as a blood pressure monitor, thermometer, glucose monitor and oxygen saturation sensor. The compute engine interfaces with the base unit and with the Internet-based storage system. The Internet-based storage system may be a web service, an Internet-based cloud service or an Internet-exposed database. Once the medical data is stored in the Internet-based storage system, the medical data may be sent to the patient, an electronics medical records (EMR) system, to a physician's office, and/or to any other appropriate location for analysis of the medical data.
The health care system described in this disclosure is designed to be used in a location remote from a health care provider. For example, the health care system may be used in a home environment. In other examples, the health care system may be used in applications outside the home, for example in a clinic or in a commercial setting such as a supermarket, retail store or similar setting. In this disclosure, the health care system may be referred to as a remote health care system. In addition, in this disclosure, a health care medical device may be referred to as a remote health care medical device.
The example remote health care medical device 104 is a self-contained unit that includes a plurality of medical sensor devices and the compute engine. In some examples, the medical sensor devices include a blood pressure monitoring device, a thermometer, a glucometer and an oxygen saturation sensor. More, fewer or different medical sensor devices may be used. The compute engine is a mobile electronic computing device with a display, such as a tablet computer or a smart telephone.
The medical sensor devices are attached or connected to patient 102. Medical data from the sensor devices is sent to the compute engine for display and for transmission to an Internet-based storage system. In the example system 100, the Internet-based storage system is a third party source, such as Internet cloud services 106. Ease of use of the remote health care medical device 104 is facilitated via instructions, both oral and visual from the compute engine. Ease of use is also facilitated via using the compute engine to transmit the medical information to the Internet cloud services 106.
The example Internet cloud services 106 is typically a third party Internet services provider, such as Amazon web services. In the example system 100, a health care website is hosted on Internet cloud services 106. A health care application may be downloaded from the health care website and installed on the compute engine of the remote health care medical device 104. Medical sensor data received at the remote health care medical device 104 may be transmitted to the health care website. The health care website is typically configured to send the medical sensor data to a final destination—for example the EMR system 108, a physician's office, etc. The example health care website running on Internet cloud services 106 may receive medical sensor data from a plurality of remote health care medical devices.
The example EMR system 108 is an electronic medical records system for storing medical data for patients. Example information stored in the EMR system 108 includes identification information for the patient (name, address, patient identification number) and a medical history for the patient including records of blood pressure, temperature, glucose levels, oxygen saturation and other vital sign data for the patient.
The blood pressure sleeve 202 is used to take a patient's blood pressure. The patient inserts an arm into the blood pressure sleeve 202. When a blood pressure reading is started, a blood pressure cuff inflates in the blood pressure sleeve 202. After reaching a suitable inflation, the cuff deflates and the patient's blood pressure is measured. In some examples, the blood pressure cuff automatically adjusts in position around the patient's arm to properly read the patient's blood pressure. The automatic adjustment of the blood pressure cuff ensures that blood pressure cuff is in a proper position to read the patient's blood pressure. The blood pressure sleeve 202, in conjunction with the automatic adjustment of the blood pressure cuff, also obviates the need of a patient to manually strap, secure and position the blood pressure cuff around the patient's arm.
The thermometer probe 204 and the oxygen saturation sensor 208 are typically hard-wired to the console of the remote health care medical device 104, although wireless sensors are possible. The glucometer 206 is typically a portable device. Typically, a user takes a glucose strip and puts the glucose strip into the glucometer 206. The user lances a finger and applies blood to the glucose strip. When the blood is applied to the glucose strip, the glucometer displays a glucose reading for the patient.
The tablet computer 210 comprises the compute engine for the remote health care medical device 104. As shown in
In other examples, instead of being embedded in enclosure 212, the tablet computer 210 may be secured to enclosure 212 with a mounting bracket. A plurality of mounting brackets may be designed. For example, the enclosure 212 may include a mounting bracket designed to hold and secure tablet computer 210. In other examples, the enclosure 212 may include a mounting bracket designed to hold and secure a smart telephone. For example, in one alternative, the enclosure 212 can simply be a cradle that holds a smartphone or other similar device and allows the device to be connected to the remote health care medical device 104 using a wired connection to a USB or similar port, or using a wireless connection such as Bluetooth or Near Field Communication (NFC). Other types of mechanical assemblies or wireless connections may be used.
The enclosure 212 also includes example speaker holes 211. The speaker holes 211 provide openings so that audio from the tablet computer 110 may be heard. The audio is typically used for oral prompting and instructions during operation of the remote health care medical device 104. Oral prompting is explained later herein. In other examples, the audio may originate from the smart telephone or other similar device.
The compute engine 304 facilitates transmitting medical data from the medical sensor devices to a final destination, such as EMR system 108, a physician's office, etc. Because of the compute engine 304, a patient using the remote health care medical device 104 need not be concerned about transmitting the medical data to the final destination. The compute engine 304 transmits the medical data to Internet cloud services 106, and Internet cloud services 106, for example the health care website running on Internet cloud services 106, transmits the medical data to a configured destination, such as EMR system 108. Separating the base assembly 302 from the compute engine 304 also permits easy upgrade of the compute engine 304 when technology changes. For example, an upgrade simply consists of replacing the tablet computer or smart telephone with a newer model. Separating the base assembly 302 from the compute engine 304 also permits the base assembly 302 to be sold as a separate product, without the compute engine 304. For example, a customer may want to provide their own compute engine, such as their own tablet computer or smart telephone.
As discussed, medical sensor devices 402 may include medical sensor devices for monitoring blood pressure, temperature, glucose levels and oxygen saturation. Other medical sensor devices may be included in the remote health care medical device 104. For example, the remote health care medical device 104 may include a fall sensor that determines whether a person has fallen. In some examples, the fall sensor comprises an accelerometer that is attached to the patient near the patient's body frame. A wireless connection, for example Bluetooth, may connect the accelerometer to the compute engine 304, either tablet computer 210 or a smart telephone. In some examples, a software algorithm in the accelerometer places a variety of acceleration event magnitudes on a timeline. Events that occur in an order that resembles a patient fall cause a peak in the timeline that may be used to determine risk. A combination of events at different times can indicate that the patient has fallen.
Another medical sensor device that may be included in the remote health care medical device 104 is a weight sensor. In some examples, the weight sensor may be installed on a chair that may be part of the remote health care medical device 104. When the patient sits on the chair, the patient's weight is measured by the weight sensor. In some examples, the weight sensor may be a capacitive sensor. In some examples, the capacitive weight sensor comprises two flexible sheets with metal on both sides of the sheets. An insulator, such as a piece of rubber, may be included between the two flexible sheets. When the patient sits on the chair, the flexible sheets press against the rubber, resulting in a change of the capacitance of the weight sensor. Changes in capacitance can be correlated into changes of the patient's weight, and in this manner the patient's weight can be measured. Other types of weight sensors may be used.
In some examples, the remote health care medical device 104 may include a general purpose camera for viewing of the patient. Standard video technologies such as Skype or Face Time may be used to establish a connection with the camera. For example, the camera may be connected to a physician's office and used to examine the patient or to observe certain areas of the patient's body. The physician may be able to make a diagnosis using the camera. In some examples, the camera may be used by a clinician, for example a nurse, to verify that the patient has taken prescribed medication. For example, the patient may use the camera to show the clinician a pill box with the prescribed medication. The clinician may verify proper medication by the size, shape and color of the medication and also verify that the patient has taken the proper medication for a particular day. Other uses for the camera are possible.
In some examples, the remote health care medical device 104 may include additional user interfaces. For example, the tablet computer 210 may provide a manual input, for example via a touch screen, wherein the patient may answer a series of questions about what they are doing at the time they are using the remote health care medical device 104 and answer other questions such as medications taken, foods eaten, etc. In addition, alerts, such as an audible alarm or a telephone call, may prompt the patient to take readings on the remote health care medical device 104. Further, a doctor may be alerted if a patient is non-compliant. There may also be an early warning notification system, via messages on the tablet computer 210 or smart telephone when measured readings exceed a predetermined threshold. Alerts may also be provided when a determination is made that one or more medical sensor devices are producing invalid readings.
Other features of the remote health care medical device 104 may include transmitting medical sensor data to an artificial intelligence tool made available by Internet cloud services 106. For example, the artificial intelligence tool may determine trends from the medical data and may provide the trends to a physician for review.
Another feature may be to configure the Internet cloud services 106 to format information received from the remote health care medical device 104 in different ways and to direct the information to different parties. For example, Internet cloud services 106 may send all medical sensor data received from the remote health care medical device 104 to a physician and to EMR system 108. However, Internet cloud services 106 may direct a subset of the medical sensor data to an insurance company and Internet cloud services 106 may add billing codes to the medical sensor data before sending the medical sensor data to the insurance company.
As an additional use of Internet cloud services 106, a patient's medical records may be stored on Internet cloud services 106. Any medical sensor data sent to Internet cloud services 106 for the patient may be stored in the patient's record on the Internet cloud services 106. Once the patient's medical record is stored on Internet cloud services 106, a copy of the record may be made available to authorized medical personal, for example in an emergency situation. This concept may be similar to a patient wearing a medical alert bracelet or a dog tag that contains emergency medical information for the patient. An example of an Internet based-third party solution for storing a patient's health data is Microsoft Health Vault.
A further feature may be to adapt Internet cloud services 106 so that the medical sensor data may be directed to a large number of EMR systems. In practice, EMR systems may have different interfaces. By using a standard formatting technique such as XSLT (the extensible style sheet language transformation), the medical sensor data may be compatible with a larger number of EMR systems.
An additional feature may be the use of smart alerts. The remote health care medical device 104 may be programmed to perform periodic self-tests of medical sensor devices. When a determination is made that a medical sensor device is not working properly, instead of displaying a cryptic error message on the tablet computer 210, the remote health care medical device 104 may display a more user friendly message on the tablet computer 210. In addition, a more technical based error message may be sent to Internet cloud services 106 for transmission to maintenance personnel.
After the Start button is pressed, screen 600, shown in
After an appropriate time for the user to view screen 600, for example after a few seconds, screen 700, shown in
In example embodiments, the transitions between each screen can be manually-actuated or automatic. For example, a button or other similar prompt can be provided to allow the patient to manually move through each screen. In another example, the system can be configured to automatically move between screens based upon elapsed time or sensors. For example, the system can sense when a blood pressure cuff is removed from the device and provide instructions upon the removal. Other configurations are possible.
At operation 1902, a medical sensor device operation is initiated. The medical sensor device operation may be one of obtaining a patient's blood pressure, measuring the patient's temperature, obtaining a glucose level for the patient, measuring the oxygen saturation level for the patient or some obtaining other medical data for the patient. The operation is initiated at the remote health care medical device 104. In some examples, the remote health care medical device 104 is programmed to initiate the medical sensor device operation at a particular day and time. In other examples, the patient may manually initiate the medical sensor device operation, for example by pressing a button on the remote health care medical device 104.
At operation 1904, medical data is received from the medical sensor device. The medical sensor data received from the medical sensor device is typically raw sensor data. Raw sensor data may include pressure data, heat data, blood data, electrical data, wavelength data, etc.
At operation 1906, the raw sensor data is converted into an appropriate format. Typically, each sensor device includes processing electronics that converts the raw data into the appropriate format. The processing electronics may include a processor, whereby a software algorithm running on the processor may implement the conversion. For example, pressure values from a blood pressure monitor may be converted into a systolic and diastolic blood pressure for the patient, heat data from an electronic thermometer may be converted into a temperature reading for the patient, blood data from a glucometer may be converted into a glucose level for the patient and wavelength data from an oxygen saturation sensor may be converted into an oxygen saturation reading for the patient.
At operation 1908, the formatted medical data is displayed on a display device. The display device is typically a display device that is part of the remote health care medical device 104, such as tablet computer 210 or a smart telephone. In some cases, for example for the remote health care medical device 104 shown in
At operation 1910, the formatted medical data is sent to an Internet cloud service. The Internet cloud service is typically a third party service, for example Amazon web services. In some examples, the Internet cloud service hosts a web site for the formatted medical data. The web site may be configured to obtain the formatted medical data from remote health care medical device 104 and to send the formatted medical data to a different destination, for example an EMR system.
At operation 1912, the Internet cloud service sends the formatted medical data to the EMR system, for example to EMR system 108. The EMR system stores the formatted medical data in a database on the EMR system or in an external database. In some examples, the third party cloud service is configured to send the formatted medical data to the EMR system when the formatted medical data is received at the third party cloud service. In other examples, the EMR system periodically polls the third party cloud service to request formatted medical data that is received at the third party cloud service. In some examples, the formatted medical data may be sent directly to a physician in addition to or in lieu of being sent to the EMR system.
Oral and visual prompts are used throughout the example method 1900 described above. In some examples the visual prompts shown in
