The present invention relates to therapy systems. As the baby boomers age, healthcare providers and financing providers, such as Medicare and private insurers, will be stressed by high demand, relative to supply. Insurance is well known in the art, with managed care strategies that include insurers in medical decisions, but healthcare costs have grown to 16% of GDP, with projections for 20% by 2015. Nationalized solutions result in rationing, waiting lines, and overcrowding. Supply-centered solutions would offer more doctors, nurses, and clinics, but a massive expansion could impact the quality of care, disrupt established providers, and discourage investors. Taxes can be raised to cover spending, but estimates show Medicare's total unfunded liability to be over $70 trillion. There is an unmet need for systems that will help the Medicare trustees grow and preserve the fund. Post-process audits and investigations for misbehaving members, are well known in the art. But, there is an unmet need for feedback early in the process to help the trustees find members of the Medicare system who promote safety and savings; to calculate and offer them early incentives. This system automatically generates feedback useful for determining early incentives.
Arthritis is the nation's leading cause of disability, with estimates showing that one in five adults in the nation are affected by arthritis. The limited supply of providers helping arthritis patients will be stressed by increasing demand as the baby boomers age. This system offers savings, balanced neuromuscular development, massage, controlled delivery of medication, and feedback, from the comfort of the patient's home.
Disclosed is an exercise and therapy system. It provides resistance exercise, massage, and medication. It provides means for monitoring, delivering, and controlling therapy. It generates therapy information that is useful for patients and providers.
The above and other aspects, features and advantages of the present invention will be more apparent from the following more particular description, along with the following drawings wherein:

In operation, the monitored therapy system, quantifies motion, force, work done, as well as the number and speed of repetitions performed. In this embodiment, the compressible substance 614 has a chamber 616 inside which is used to for measuring pressure resulting from the force as applied onto the compressible substance 614. The chamber 616 is filled with air, a gas, a fluid or a gel through the fill tube 630 that extends from the compressor/pressure transducer module 620 into the compressible substance 614. The compressor/pressure transducer module 620 is typically controlled by a separate controller. Thus, when pressure is applied to the compressible substance 614, a portion of the content within the chamber 616 is forced out through the fill tube 630 into the compressor/pressure transducer module 620. The pressure transducer portion of the compressor/transducer module 620 translates this push of gas, fluid, or gel into a signal proportional to or representing the pressure or force applied against the compressible substance 614. This signal is output using output means 632. Valves may be used at the entry of the fill tube 630 into the chamber 616 to help establish the required pressure level within the chamber 616.
The compressor portion of the compressor/pressure transducer module 620 is a pneumatic or fluidic component, which uses a compressor or pump. This compressor is a miniature mechanical compressor, such as those commercially available from Gast located in Benton Harbor, Mich. or Medo USA of Hanover Park, Ill. or Sensidyne of Clearwater, Fla., and are used to inflate the compressible substance to a therapeutic pressure. The compressor may be a part of the compressor/pressure transducer module 620 as shown or may be a separate unit that is worn on the body of the patient (e.g. on the patient's belt) or placed nearby the patient and attached to the compressible substance 614 via a tube. The timing and rate at which the compressor inflates or pressurizes the chamber 616 within the compressible substance 614 maybe set by a separate controller. Alternatively, a squeezable ball, such as used in blood pressure cuffs, may be used to for inflation, or a miniature tank of compressed gas. Furthermore, valves may be used in addition to the compressor. For example, micro solenoid valves like those used in inkjet printers or pinch valves like those used in pneumatic systems can be used to control the air or fluid flowing in and out of the chamber 616 of the compressible substance 614. Such valves could be open or shut, or pulsed, working in concert with the compressor or pump to control the pressure in the chamber 616 (or chambers) and the rate at which they are inflated or filled. These valves are readily available, such as commercially available from Lee Company of Westbrook, Conn. or SMC, located in Indianapolis, Ind.
The pressure transducer portion of the compressor/pressure transducer module 620 is a transducer that produces a signal proportional to the pressure applied to its port, which is proportional to or represents the pressure or force applied by the patient. Typically, the port of the pressure transducer is positioned at the end of the fill tube 630 within the compressor/pressure transducer module 620 so that the gas or fluid that is forced from the chamber 616 of the compressible substance 614. In response to the pressure against the port of the pressure transducer, the pressure transducer outputs a signal that is proportional to or represents the pressure inside the chamber 616. Such pressure transducers are well known in the art and are commercially available from Honeywell located in Minnesota. In this embodiment, the compressor/pressure transducer module 620 uses output means 632 that is linked to the computer interface 634, which in turn may be linked to a controller of a therapy system. Medication (not shown) may be contained in various locations throughout the system.
The displacement transducer module 618 provides the means for measuring motion or the distance traveled during extension and flexion. One embodiment of a displacement transducer module 618 is a rotary encoder system. Within the displacement transducer module 618, a shaft of the rotary encoder is coupled to a spool or roller carrying the line 624. Ideally, the spool or roller is spring loaded so that the line 624 is pulled tight from the anchor 628 to the spool of the displacement transducer module 618. The distal end of the lines 624 are attached to an anchor 628. The lines 624 pass through respective line guides 626. Alternatively, the lines 624 may pass through a flexible protective tubing so as to protect the lines during use.
In use, during flexion, the lines 624 are drawn from the spool causing the rotary encoder to transmit electrical pulses whose number is in proportion to the flexing and movement. The stiffness of the line 624 returning through the line guides 626, or a light-force spring return mechanism in the spool or roller would return the line 624 back onto the spool or across the roller during extension, providing extension and flexion displacement data. Thus, the rotary encoder can determine the magnitude of the movement, so that a complete range of movement while opening and closing the hand may be modeled. The displacement transducer module 618 will output a signal over output means 632 to the computer interface 634 that is proportional to or represents the displacement.
Alternative means for monitoring displacement include the use of strain gauge transducers. These sensors produce an electrical signal in proportion to motion. They work on a variety principles: piezo electric, electro mechanical (like a condenser microphone), accelerometer, goniometer, and variable resistance strain gauge. These transducers, and their detector circuits, are readily available in scientific materials catalogs like Cole Parmer, located in Vernon Hills, Ill. Other examples of monitoring means and wearing means, are shown in U.S. Pat. No. 5,280,265 issued Jan. 18, 1994 to Kramer, et al., entitled “STRAIN SENSING GONIOMETERS, SYSTEMS AND RECOGNITION ALGORITHMS”; in U.S. Pat. No. 4,414,537, issued Nov. 8, 1983 to Grimes entitled “DIGITAL DATA ENTRY GLOVE INTERFACE DEVICE”; and in U.S. Pat. No. 4,542,291, issued Sep. 17, 1995 to Zimmerman entitled “OPTICAL FLEX SENSOR”, all of which are incorporated herein by reference. The preferred means for monitoring motion are not meant to be limiting, as those skilled in the art can modify a preferred embodiment without departing from the scope or spirit of the invention.
Additionally, a thermal transducer 622 is positioned within the monitored therapy system device 600. The thermal sensor, measures the temperature change during exercise, providing a calorimetric estimate of work. This feedback can be used as simple and expensive way to measure the progress, and enhance a patient's therapy.
Thus, monitoring means can provide outputs that represent force, temperature, and motion during exercise. These output signals may also be used to determine the number and speed of repetitions. Additionally, the system includes means for linking to a computer system that may be used to display and store the measurements and/or control the pressure within the chamber 616 of the compressible substance 614. A therapy provider can monitor the results of therapy sessions, and use the performance feedback to make recommendations for enhancing the therapy.

The patient 1020 interacts with a therapy device 1010, that provides flexion resistance exercise, extension resistance, exercise, massage, medication, and medication delivery control. The electrodes 1018 receive signals from the SCCE 1030 that control the transdermal delivery of medication 1017. The pneumatics/fluidics module 1014 may also receive signals from the SCCE 1030 that control pressure to inflate or deflate the compressible substance 1012, or deliver or remove medication 1017. In operation, the monitored therapy system 1000 provides means for measuring the motion, force and work done by the patient. Furthermore, it provides a means for controlling, the pressure resistance of the compressible substance 1012, and the delivery of medication 1017 automatically, so that therapy parameters can be set, monitored, and maintained automatically by the patient's 1020 or therapy provider's 1042 interaction with the SCCE 1030.
In this embodiment, both the patient 1020 and the therapy provider 1042 are operators of the SCCE 1030. In other embodiments, it may be advantageous for a training provider 1044, equipment provider 1054, or pharmaceutical provider 1052 to interact directly or remotely with the SCCE 1030 to help novice users. Both the patient 1020 and the therapy provider 1042 can set the therapy parameters such as resistance pressure, or range of motion goals, and will review the therapy outcomes such as joint movement, pressure or force applied, or work done. Over time, the therapy provider 1042 will adjust the therapy parameters to reflect the best plan of treatment. The therapy provider 1042 may interact remotely through the SCCE 1030 to control the therapy device 1010, or by making recommendations to the patient 1020 regarding adjustments.
A computer (not shown) could be physically integrated with the SCCE 1030, located in its vicinity, or connected via a network link. It provides a way for the therapy provider 1042 to adjust parameters and review treatment, locally and remotely. It stores and organizes therapy parameters and outcomes in a database for archival and ready access. It also converts outcomes data into a graphical charts displayable on a computer terminal and printable on paper that ease the interpretation of the outcomes data and help the providers make better recommendations. The SCCE 1030 might be a standalone unit, located near the patient 1020, or it might be a miniature battery operated controller that is integrated, for example as an attachment to the therapy device 1010. The SCCE 1030 receives and generates signals to and from various sources throughout the system 1000, and contains the algorithms necessary to translate the signals from the various transducers 1031 into the respective estimations of actual displacement, temperature and force or pressure applied. Such algorithms for translating these conventional signals supplied by conventional transducers are well known in the art; thus, no further explanation is required. The SCCE 1030 is also able to determine the number of repetitions and speed of repetitions, for example, by comparing the direction of the displacement signals received and when the signals “change direction” (indicating a change from extension to flexion, for example) to a timer or clock. The SCCE 1030 also sends control signals to the compressor to set the resistance. The SCCE 1030 translates the signals from the transducers 1031, and maintains communications between the therapy device 1010, and its users. It could contain a custom computer, such as a microcomputer or personal digital assistant, or a common personal computer running commercially available software, such as National Instruments' Labview. The control panel 1037 consists of knobs, buttons and displays 1039 that allow the user to set therapy parameters and review therapy outcomes. These knobs, buttons and displays are electronically connected to the SCCE's 1030 embedded computer. The control panel 1037 may be configured so that the patient 1020 or therapy provider 1042 can: set the initial and final pressure resistance level of the compressible substance 1012; set a repetitions counter or therapy timer; set limits and alarms for excess pressure or other abnormal conditions; set control parameters such as PID (proportional, integral, derivative) constants; store parameters for future use; and control the power for the SCCE 1030. Additionally, the control panel 1037 may provide a display 1039 indicating real time indications of pressure, displacement, and work, as well as graphical displays of such measurements. Additionally, the therapy settings may be shown. Such displays may be displayed on a corresponding computer or on a screen or display 1039 of the SCCE 1030 itself depending on the embodiment. The knobs, buttons and displays comprising the control panel 1037 are commercially available from many sources as discrete components or integrated into control panel assemblies. Displays are widely available in the following forms: LED alphanumeric displays, LCD alphanumeric and graphic displays, electro luminescent and plasma displays, and cathode ray tubes.
The SCCE 1030 allows the pressure resistance to be adjusted automatically in dynamic response to predetermined pressure profiles and sequences, existing pressure in the chamber/s of the compressible substance 1012, motion, and the work being done. The feedback control 1036 is a function performed by the SCCE's embedded computer. It receives the real-time pressure, displacement, and work measurements, then uses readily available algorithms, such as PID (proportional, integral, derivative) control to send the proper signals to adjust the valve settings and the compressor (within the pneumatics/fluidics module 1014), to maintain the pressure resistance within the chamber/s of the therapy device 1010 according to the therapy provider's 1042 or patient's 1020 settings. The feedback controller 1036 contains therapy data storage circuits, parameter storage circuits, and a real time clock that permit it to operate autonomously.
The SCCE 1030 communicates with the therapy device 1010. It outputs signals to the pneumatic/fluidic module 1014, to control the amount of pressure that the chambers are inflated to, and to the electrodes 1018, to control the delivery of medication 1017. These output signals might be pulsed waveforms intended to switch the compressor and valves on and off, or to induce electroporation, or they may be analog voltage signals intended to set the compressor speed. The SCCE 1030 also receives signals from the transducers 1031, e.g. pressure transducer, displacement transducers and thermal transducer. These received signals might be pulsed waveforms, or analog voltage levels as output from the respective types of transducers 1031.
Additionally, the SCCE 1030 may perform communications via the communications provider 1070, typically with a therapy provider 1042. Thus, the therapy provider 1042 may be located at another location than the patient 1020. Advantageously, the patient 1020 may operate the monitored therapy system 1000 at home and be simultaneously monitored by the therapy provider 1042. Thus, a service provider 1040 can send signals to the SCCE 1030 via the communications provider 1070 to control or set the parameters of the patient's 1020 session in accordance with a therapy plan, or in response to the measurements. Advantageously, the providers can see the results of the session and provide diagnostics, advice, or make therapeutic changes to further enhance the therapy, from a remote location. Furthermore, a provider computer (in addition to or instead of the SCCE 1030) may also be capable of translating the signals output from the transducers into the appropriate measurements of displacement, work, pressure or force, and the number and speed of repetitions. Advantageously, the monitored therapy system provides a system that other members, such as advice providers 1043 or financing providers 1060 could connect to and interact with. Thus, a financing provider 1060 can monitor, or verify that therapy session data was stored (and can be later retrieved), to facilitate the immediate transfer of funds to the service provider's 1040 account (not shown). Monitoring and storage and systems are well known and commercially available from Nice Systems, Motorola, Diebold, or Logitech. Storage, search, and retrieval systems for complex databases are commercially available from Teradata or TRW. Knowing that the therapy session has been electronically stored, a financing provider 1060 can recommend immediate incentives (not shown) such as discounts to encourage members who reduce facility and transportation costs by participating in remotely monitored therapy. Such stored session information is also useful as unambiguous evidence that can help reduce costs for legal services, and help amicably settle disputes.
The SCCE 1030 will comprise many different circuits including: pulse width modulation circuits that will generate a pulsatile waveform to control medication delivery and pressure, digital to analog circuits to create a variable voltage level to adjust the compressor speed; driver circuits to convert the outputs from the pulse width modulator and the digital to analog circuit into the proper voltage and current to supply the valves and the compressor; transceiver circuits to convert the pulsed waveform from the displacement transducers into a computer readable form; analog to digital circuits to convert the signals from the displacement transducers, temperature sensors, and pressure transducers into computer readable form; and also data communication circuits such as a modem, Ethernet transceiver, USB transceiver, infrared or RF transceivers, or a simple serial interface to allow connection to the computer (e.g. the therapist's computer if it is located nearby). These circuits are commercially available as add-on-boards for personal computers through companies like National Instruments located in Austin, Tex. They are also readily constructed from available components from electronics components made by manufacturers like Texas Instruments (located in Dallas, Tex.) and National Semiconductor (located in Santa Clara, Calif.), available through distributors and catalog sources like DigiKey and Newark Electronics. The circuits themselves are well-understood and are described in readily available reference books.
The pneumatics/fluidics module 1014 receives signals from the SCCE 1030, either generated by the therapy provider 1042 or the patient 1020, to regulate the air or fluids going into and out of the compressible substance 1012. Thus, the SCCE 1030 sends the appropriate signals to make sure the pressure within the compressible substance is as desired. Again, as described above, the pneumatics/fluidics module may comprise an electronically controlled compressor (or pump) and/or valves. The compressible substance 1012 is also as described above and includes a flexible enclosure containing one or more chambers within the compressible substance 1012. The compressor and/or valves (of the pneumatics/fluidics module 1036) would be connected to the fill tubes leading to each chamber, to establish air or fluid pressure in each chamber and to regulate the flow in and out of each chamber. The transducers 1031, provide the measurements in the form of signals so that determinations of motion, force while squeezing the compressible substance, a calorimetric estimate of the work done can be obtained by the SCCE 1030, along with the number and speed of repetitions.
The patient 1020 wears the therapy device 1010 and interacts with the compressible substance 1012 and elastic members 1016. The system may include medication 1017 and electrodes 1018 on the interior surface of the glove 1019. The electrodes 1018 are linked to the SCCE 1030 to monitor and control the transdermal delivery of the medication 1017. Precise estimates of drug absorption can be transmitted and displayed for the patient 1020 on the display 1039, or for a provider. If analysis of variables such as duration, number of repetitions, medication concentration, electrode activity, temperature or other measurements indicate an anomaly, then alarms can be displayed and the therapy parameters appropriately adjusted. A skilled artist could easily alter this embodiment by swapping or positioning sensors, or transducer modules, in various locations without departing from the spirit of the invention.

In operation, the hand therapy system works 1100 with the glove 1110 to provide a means for measuring the motion, force and work done by the patient 1110. Furthermore, it provides a means for controlling the pressure resistance of the compressible substance 1122 of the glove 1110 automatically, so that therapy parameters can be set and maintained automatically by the patient's or therapist's interaction with the controller 1108.
The therapist/patient block 1102 represents both the patient and the therapist. As shown in this embodiment, both the patient and the therapist have access to the measurements obtained using the glove 1110 in addition to being the operators of the hand therapy system 1100. Both the patient and the therapist can set the therapy parameters such as resistance pressure (of the compressible substance 1122), and will review the therapy outcomes such as joint movement, pressure or force applied, and work done. Over time, the therapist will adjust the therapy parameters to reflect the best plan of treatment. The therapist may interact with the hand therapy system 1100 directly through the computer 1104 or remotely over a computer network via the computer link 1106, such as the Internet link. The computer 1104 is either physically integrated with the controller 1108 in a monolithic enclosure, located in the vicinity of the controller 1108, or connected to the controller 1108 via a computer network (e.g. the internet) through the computer link 1106 (e.g. an internet link). It provides a readily accessible way for the therapist to adjust parameters and review treatment, locally and remotely. The computer 1104 stores and organizes therapy parameters and outcomes in a database for archival and ready access. It also converts outcomes data into a graphical charts displayable on a computer terminal and printable on paper that ease the interpretation of the outcomes data and help the therapist make better decisions.
The controller 1108 is the electronic brain of the hand therapy system 1100. It might be a standalone unit, located near the patient, or it might be a miniature battery operated controller that is integrated onto the glove (e.g. as an attachment to the compressor/pressure transducer module or the displacement transducer module). The controller 1108 receives signals from the transducers 1124 of the glove representing finger displacement (from the displacement transducers), force applied (from the pressure transducers) and work (measured as a calorimetric estimate from the thermal transducer) and contains the algorithms necessary to translate the signals from the various transducers into the respective estimations of the finger displacement, temperature and force or pressure applied. The controller also sends control signals to the compressor (within the pneumatic/fluidics module 1120) of the glove to set the glove's resistance (e.g. the compressor and valve settings). The controller 1108 contains an embedded computer that manages the activities of the controller, translates the signals from the transducers, and maintains communications between the controller 1108, the glove 1110, and its users. It could be a custom computer, or be a common personal computer running commercially available software, such as National Instruments' Labview.
The controller 1108 is comprised of the subsystems of the feedback controller 1116, control panel 1114 and the IO 1118. The control panel 1114 consists of knobs, buttons and displays that allow the user to set therapy parameters and review therapy outcomes.
Theses knobs, buttons and displays are electronically connected to the controller's 1108 embedded computer. The control panel 1114 may be configured so that the user can: set the initial and final pressure resistance level of the compressible substance 1122 within the glove; set a repetitions counter or therapy timer; set limits and alarms for excess pressure or other abnormal conditions; set control parameters for the feedback controller 1116, such as PID (proportional, integral, derivative) constants; store parameters for future use; and control the power to the controller 1108.
Additionally, the control panel 1114 may provide a display indicating real time indications of pressure, displacement, and work in aggregate or on a finger by finger basis, as well as graphical displays of such measurements. Additionally, the glove settings may be shown. Such displays may be displayed on a corresponding computer or on a screen or display of the controller itself depending on the embodiment.
The feedback controller 1116 allows the pressure resistance of the compressible substance 1122 to be adjusted automatically in dynamic response to predetermined pressure profiles and sequences, existing pressure in the chamber/s of the compressible substance 1122, finger motion, and the work being done. The feedback controller 1116 is a function performed by the controller's embedded computer. It receives the real-time pressure, displacement, and work measurements, then uses readily available algorithms, such as PID (proportional, integral, derivative) control to send the proper signals to adjust the valve settings and the compressor (within the pneumatics/fluidics module 1120), to maintain the pressure resistance within the chamber/s of the glove 1110 according to the user's settings. The feedback controller 1116 contains therapy data storage circuits, parameter storage circuits, and a real time clock that permit it to operate autonomously.
The IO 1118 allows the controller 1108 to communicate with the glove 1110 and the computer 1104. The IO 1118 outputs signals to the pneumatic/fluidic module 1120, which contains the compressor and the valves, to control the amount of pressure that the chambers are inflated or filled up to in order to provide the appropriate resistance when the patient squeezes the compressible substance 1122. These output signals might be pulsed waveforms intended to switch the compressor and valves on and off, or they may be analog voltage signals intended to set the compressor speed. The IO 1118 also receives signals from the transducers 1124, e.g. pressure transducer, displacement transducers and thermal transducer. These received signals might be pulsed waveforms, or analog voltage levels as output from the respective types of transducers 1124.
Additionally, the IO 1118 may perform data communications with the computer 1104 via the computer link 1106. The computer 1104 is typically the therapist's computer, which may be physically attached to the controller 1108 through serial interfaces or may be linked via a computer link 1106 to the controller. The computer 1104 may be part of a local area network or wide area network or other computer network. Thus, the therapist may be located at another location than the patient. Advantageously, the patient may operate the hand therapy system 1100 at home and be simultaneously monitored by the therapist online with the controller 1108. Thus, the therapist can send signals from the therapists computer 1104 to the controller 1108 via the computer link 1106 (such as an internet link) to control or set the parameters of the patient's session in response to the measurements of the glove 1110. Advantageously, the therapist can see the results of the session (i.e. the estimations of finger displacement, work, force or pressure, and the number and speed of repetitions) and recommend desired changes to further facilitate improve in a patient's condition without having to be physically present at the session. Furthermore, the computer 1104 (in addition to or instead of the controller 1108) may also be capable of translating the signals output from the transducers into the appropriate measurements of displacement, work, pressure or force, and the number and speed of repetitions.
The IO 1118 will comprise many different circuits including: pulse width modulation circuits that will generate a pulsatile waveform to control the compressor and valves of the pneumatics/fluidics module 1120; digital to analog circuits to create a variable voltage level to adjust the compressor speed; driver circuits to convert the outputs from the pulse width modulator and the digital to analog circuit into the proper voltage and current to supply the valves and the compressor; transceiver circuits to convert the pulsed waveform from the displacement transducers into a computer readable form; analog to digital circuits to convert the signals from the displacement transducers, temperature sensors, and pressure transducers into computer readable form; and also data communication circuits such as a modem, Ethernet transceiver, USB transceiver, infrared or RF transceivers, or a simple serial interface to allow connection to the computer (e.g. the therapist's computer if it is located near the IO 1118).
The glove 1110 comprises the pneumatics/fluidics module 1120, the compressible substance 1122, and the transducers 1124. The pneumatics/fluidics module 1120 contains the compressor and appropriate valves of the compressor/pressure transducer module described earlier. The pneumatics/fluidics module 1120 receives signals from the controller 1108, either generated by the therapist or the patient, to regulate the air or fluids going into and out of the compressible substance 1122. Thus, the controller 1108 sends the appropriate signals to make sure the pressure within the compressible substance is as desired. Again, as described above, the pneumatics/fluidics module may comprise an electronically controlled compressor (or pump) and/or valves.
The compressible substance 1122 is also as described above and includes a flexible enclosure containing one or more chambers within the compressible substance 1122. The multi-chamber compressible substance as shown in
The transducers 1124, as described above as the pressure transducer, the displacement transducer, and the thermal transducer, provide the measurements in the form of signals back to the controller 1108 so that determinations of finger motion, force exerted by each finger or the hand total while squeezing the compressible substance, a calorimetric estimate of the work done can be obtained by the controller 1108, and the number and speed of repetitions.
The patient's hand 1112 fits within the glove 1110 and interacts with the compressible substance 1122. The glove 1110 is designed to snugly fit the patient's hand 1112 and contains the transducers 1124 required to obtain the measurements. Additionally, the glove may be embodied as described above, including the addition of medication on the interior surface of the glove 1110. The glove 1110 will fit properly to the patient's hand 1112 and will provide resistance to motion that is therapeutically appropriate. Furthermore, the glove 1110 will position and anchor the transducers 1124 and compressible substance 1122 so that the measurements are sufficiently accurate and precise.

In practice, the compressor/transducer module 1206 pumps materials, such as gas, air, fluids, or gels into the chamber or chambers (not shown) of the compressible substance 1202 and provides the means for measuring the force exerted by the fingers (i.e. fingers and thumb) of the patient's hand upon squeezing the compressible substance 1202. The embodiment shown in
In order to inflate the chamber/s within the compressible substance 1202, the compressor 1218 pulls air through the filter 1221 via tube 1234 and forces the air out through tube 1232. The compressor, which is a miniature mechanical compressor as described above with reference to
Air is also pumped into tube 1222 from the first tee 1208 to the vent solenoid 1212, which acts as a valve; however, during the “pumping” of the compressor 1218, the vent solenoid 1212 is closed such that the air will not be allowed to flow through the vent solenoid 1212. The vent solenoid 1212 is controlled via signals sent through wire 1236.
Furthermore, air is forced against the port of the pressure transducer 1216 through tube 1228 of the second tee. The pressure transducer 1216 of the compressor/pressure transducer module 1206 is a transducer that produces a signal, such as a voltage proportional to the pressure applied to its port. The pressure transducer 1216 is used during inflation to determine when the desired pressure (e.g. desired psi) within the compressible substance 1202 has been reached. Wire 1238 of the pressure transducer 1216 transmits the voltage signals proportional to the pressure within tube 1228 to the controlling computer (to translate the signals into estimation of pressure) through the interface port 1244 and the interface means 1246. Such information is used to control the switching on and off of the compressor 1218. The compressor 1218 is well known in the art as described with reference to
Once the pressure within the chambers of the compressible substance 1202 is at the desired level, i.e. the pressure at the pressure transducer 1216 is at the desired level, the pump solenoid 1210 is closed and the patient squeezes the compressible substance 1202, which forces air back into the first tube 1204 and causes more pressure to be placed upon the pressure transducer 1216. Thus, the pressure transducer 1216 sends voltage signals which are proportional to the additional pressure within the system, which can be translated, by the controller of
Additionally, the vent solenoid 1212 may be employed to vent the system; thus, allowing rapid deflation of the compressible substance 1202 upon completion of the therapy. In this case, the vent solenoid 1212 is opened, while the pump solenoid 1214 is closed. Thus, the air contained within the compressible substance 1202 and the system will be pushed out through tube 1222, through the vent solenoid 1212, through tube 1224, and out of the compressor/transducer module 1206 through filter 1220.
The compressor/pressure transducer module 1206 may be as shown, i.e. as a separate unit not physically located on the body of the glove. Thus, the compressor/pressure transducer module 1206 may be worn on the body of the patient (e.g. on the patient's belt) or placed nearby the patient and attached to the compressible substance 1202 via the first tube 1204. Alternatively, the compressor/pressure transducer module 1206 may be integrated onto the body of the glove, as described above with reference to
Furthermore, for a compressible substance 1202 including more than one chamber, e.g. one chamber for each finger, there are five separate pressure transducers 1216 within five separate compressor/pressure transducer modules 1206. Thus, there is one compressor/pressure transducer module 1206 for each respective chamber of the compressible substance 1202. Alternatively, there may be one compressor/pressure transducer module, including 5 pressure transducers all sharing the same compressor and/or sharing common vent solenoids.

Referring back to step 1310, when the financing provider offers incentives: there is an unmet need for incentives for protecting funds managed by healthcare financing providers, such as Medicare. For example, Medicare funds might be readily available for limosine or air travel for non-emergency therapy sessions, without any incentive to save by choosing remotely monitored home therapy. Other questionable factors that providers employ include items such as broadcast advertising, or legal expenses for unsafe pills. For example, recent broadcast television ads promote motorized scooters that can be financed by Medicare; with company sales reps ready to assist with Medicare processing. Thus, questionable items, such as broadcast advertising and sales commissions, are passed through to the Medicare members in higher scooter prices. Restated with reference to
