SYSTEMS AND METHODS FOR THERMOELECTRIC SEQUENTIAL COMPRESSION DEVICES AND INTEGRATED THERMOELECTRIC SEQUENTIAL COMPRESSION DEVICES

FIELD

The present disclosure generally relates to devices for managing circulation, and more particularly, to sequential compression devices.

BACKGROUND

Compression devices play an integral role in the well-being of subjects. The compression devices can assist with circulation in extremities (e.g., the legs), decreasing the likelihood of various issues, such as, for example, deep vein thrombosis (DVT). Many facilities have protocols that mandate use of the compression devices unless indicated otherwise. However, subjects that wear compression devices often find them progressively uncomfortable. This can be due to the fabric of the compression device not breathing correctly because the compression device itself should be airtight allowing for inflation. In addition, the compression device is generally tight fitting so that the extremities of the subject benefit from the compression. In addition, extended operation of components causes the air that circulates within the compression device to increase in temperature, thereby heating the compression device itself. As a result, the compression device causes discomfort (e.g., the subject feels hot and uncomfortable, the subject sweats, the subject feels itchy or the like).

DETAILED DESCRIPTION

The present disclosure relates to systems and methods for thermoelectric sequential compression devices utilizing thermoelectric technology to compensate for excessive heat generated while a subject wears the thermoelectric sequential compression device. Thermoelectric foam modules are incorporated in the thermoelectric sequential compression device fabric and inflatable bladder construction, and are configured to provide heating and cooling, thus delivering enhanced subject comfort. Moreover, the thermoelectric foam modules include temperature sensors allowing for optimal temperatures to be maintained, reducing the likelihood of pressure injuries. A plurality of thermoelectric foam modules may be included for zonal heating and cooling, one per inflatable bladder of the thermoelectric sequential compression device. In other aspects, a single thermoelectric foam module may be included in the thermoelectric sequential compression device for heating or cooling. By independently, and in some aspects remotely, controlling the temperature and pressure amount of hot air and cold air supplied to any number of inflatable bladders via a user interface, monitoring and operational efficiency of the thermoelectric sequential compression device is improved and achieved in real-time. For example, a blower may be directed to provide any number of inflatable bladders with air in a sequential fashion, promoting efficient blood circulation. Unlike conventional compression devices, the thermoelectric sequential compression devices disclosed herein can be integrated with a platform where the subject does not need to sit towards the end of a bed or require a separate over-the-bed table. Because control of the temperature and pressure amount of the hot and cold air is not unrestricted, security and access permissions are particularly customized and implemented via the user interface based on a user type for thermoelectric sequential compression device operation control, including controlled administration of a therapeutic temperature and pressure operation control.

While the present disclosure relates specifically to medical surgical rooms including subject monitors and hospital beds, it should be understood that this is merely an example. That is, the systems and methods described herein may be used for any type of medical equipment, either within the medical surgical rooms or outside the medical surgical rooms, that is configured to provide power and/or control of sequential compression devices, including, but not limited to, overhead lifts, vital monitoring equipment, control devices, wall-mounted displays, nurses station equipment, surgical equipment, furniture, wheelchairs, and the like.

As depicted in FIG. 3, and in certain aspects, the first layer 118 may be disposed above the second layer 122, such as relative to a +Y direction of the coordinate axes of FIG. 3. In certain aspects, the first layer 118 may include a lower density value than that of the second layer 122. The second layer 122 may be configured to include, as compared to the first layer 118, denser non-permeable foam to create and support the plurality of channels 116 with channel walls that avoid collapse under pressure. In certain aspects, and without limitation, an indentation load deflection for the first layer 118 may range between about 12 to 27, such as between about 15 to 24, and an indentation load deflection for the second layer 122 between about 30-93, such as between about 33-90. Thermoelectric cooler junctions 124 may be positioned between the two layers, here between the first layer 118 and the second layer 122, and braided-wire connectors 126 to create a thermal interface with the subject on top and with moving air underneath. In some aspects, the plurality of thermoelectric modules 114 may each include a plurality of coils. A temperature difference, due to the Peltier effect, between ends of each coil, may be generated by heat transfer such that current running in one direction across the coil achieves a warming effect, and reversing current in an opposite direction achieves a cooling effect. In certain aspects, a power source 128 may be connected to the plurality of thermoelectric modules 114, and supply the current to a closed loop defined by the ends of each coil. The power source 128 may be controlled by a processor, such as the processor 102, to supply the current.

The plurality of channels 116 may be disposed through the foam sheet 113. In certain aspects, each of the plurality of channels 116 may be disposed through each of the first layer 118 and the second layer 122 (e.g., disposed in the +Y direction of the coordinate axes of FIG. 3). The inlet 119 may be formed in a wall of the second layer 122 relative to the Y-axis direction. The inlet 119 may include any shape and/or size. A passage 130 of the second layer 122 may be disposed in the X-axis direction of the coordinate axes of FIG. 3, and partially define a portion of the inlet 119. The inlet 119 may supply air to the outlet 121 through the passage 130.

The outlet 121 may be formed in a wall opposite to that of the first of the inlet 119, and relative to the Y-axis direction of the coordinate axes of FIG. 3. The outlet 121 may include any shape and/or size. The outlet 121 may be similar or different to the shape and/or size of the inlet 119 (e.g., correspond to the shape and/or size of the inlet 119). The outlet 121 may be located at an opposite end of the inlet 119, and disposed below the inlet 119 relative to the Y-axis direction of the coordinate axes of FIG. 3. In certain aspects, the passage 130 may define both the inlet 119 and the outlet 121 through which cool air is supplied via the inlet 119 and passed through the outlet 121 as hot air relative to the X-axis direction of the coordinate axes of FIG. 3.

Ingress of air supplied by a blower 115 may enter via the inlet 119, such as an air inlet, of the foam sheet 113, which traverses (as indicated by the arrows and direction of flow relative to the +X axis direction of the coordinate axes of FIG. 3) through the foam sheet 113 and exits via the outlet 121, such as an air outlet. For example, a fan 123 may be communicatively coupled to the outlet 121, which is configured to exhaust hot air during a cooling mode operation. In certain aspects, at least one of the plurality of channels 116, such as the heat exhaust channel 117, is used for thermoelectric cooling by exhausting heated air from a passage, such as the passage 130, out via the outlet 121. The cooling mode operation of the thermoelectric sequential compression device 120 may include exhausting of the hot air to promote optimal cooling.

In certain aspects, each of the plurality of thermoelectric modules 114 may be independently controlled by a processor, such as the processor 102, to sequentially supply and maintain hot air and cold air in accordance with respective predetermined threshold values for temperature control and/or pressure control. For example, each of the plurality of thermoelectric modules 114 may be independently controlled by a user interface 106, which is communicatively coupled to the processor 102, to sequentially supply and maintain the hot air and cold air in accordance with respective predetermined threshold values. In certain aspects, each of the plurality of thermoelectric modules 114 may be controlled by the processor 102 via the user interface 106 of the user interface system 107, to supply air (as a predetermined temperature and/or predetermined pressure) to a particular body portion of the subject, as described below.

The user interface 106 may include a display that includes the predetermined temperature range control 505, the predetermined temperature range 510, and the pressure amount 515 for both right and left leg portions of a subject. In addition, the display may include the first zone 520, the second zone 530, and the third zone 540 for both right and left leg portions of the subject. By way of example, the pressure amount available for input selection, via the user interface 106, may include a “HIGH” setting, a “MEDIUM” setting, and a “LOW” setting. Alternatively and/or additionally, any pressure amount may be input via the user interface 106.

The predetermined temperature range control 505 may include a button that is configured to slide to an upper value and a lower value via the user interface 106. Upon sliding of the button, by the subject via the user interface 106, to a value within the predetermined temperature range 510, the processor 102 may be configured to set a value of the temperature supplied to a desired inflatable bladder 112. By way of example, the processor 102 may be configured to direct the blower 115 to supply a first predetermined amount of hot air at a first temperature value to a first inflatable bladder 112 of the first zone 520, direct the blower 115 to supply a second predetermined amount of cold air at a second temperature value to a second inflatable bladder 112 of the second zone 530, and direct the blower 115 to supply a third predetermined amount of cold air at a third temperature value to a third inflatable bladder 112 of the third zone 540.

In certain aspects, a first inflatable bladder 112 is arranged in a first zone 520, a second inflatable bladder 112 is arranged in a second zone 530, and a third inflatable bladder 112 is arranged in a third zone 540. Each of the first zone 520, the second zone 530, and the third zone 540 are positioned adjacent to leg portions of the subject. Without limitation, the first zone 520 may be positioned below the second zone 530, which is positioned below the third zone 540 at respective different leg portions, right and/or left, of the subject. In certain aspects, the button that is configured to slide to any value for a predetermined temperature value and/or a predetermined pressure value via the user interface 106 may correspond to a particular leg portion of the subject only. In other aspects, the button that is configured to slide to any value for the predetermined temperature value and/or a predetermined pressure value via the user interface 106 may correspond to different body portions of the subject, i.e. that is, not only corresponding to a single body portion of the subject.

It should be understood that the sequence of supplying, by the blower 115 at the direction of the processor 102, the hot air or the cold air to a particular inflatable bladder 112 of the thermoelectric sequential compression device 120 is not limited to the above example, and that any sequence of supplying the hot air or the cold air to a given inflatable bladder 112 in a given zone may be achieved via the user interface 106. For example, in one sequence, a first inflatable bladder 112 may be first supplied with air at a first temperature value and a first pressure amount, next followed by a second inflatable bladder 112 supplied with air at a second temperature value and a second pressure amount, and then a third inflatable bladder 112 supplied with air at a third temperature value and a third pressure amount. Alternative sequences are also within the scope, such as the second inflatable bladder 112 being first supplied with air at a given temperature value and a given pressure amount, or the third inflatable bladder 112 being first supplied with air at a given temperature value and a given pressure amount.

It should be understood that the input of the value of the temperature and the value of the pressure amount by the subject and/or a user is not limited to slide input via the user interface 106. Other types of input may be provided by the subject and/or the user via the user interface 106, including but not limited to audio input of the temperature value and the pressure amount value, manual input of the temperature value and the pressure amount value, or any combination thereof.

The user interface 106 may be configured to restrict temperature control of the hot air and cold air for a first predetermined temperature range input by a subject. For example, the thermoelectric sequential compression device 120 may be worn by the subject. It is further understood that the thermoelectric sequential compression device 120 is not limited to leg portions of a subject, and that other body portions of the subject may wear the thermoelectric sequential compression device 120, such as waist and arm portions of the subject. The first predetermined temperature range includes a therapeutic range. The therapeutic range may be preconfigured to allow temperature control for the hot air and the cold air to be automatically administered to the subject without any oversight or intervention. In certain aspects, the therapeutic range may not be modified by the subject.

Further, the user interface 106 may be configured to restrict temperature control of the hot air and cold air for a second predetermined temperature range input by a user, which may or may not be the subject. As referred to herein, and without limitation, the user may include an individual that is not a subject, such as a nurse practitioner, a physician, a medical assistant, a physician trainee, a caregiver, or the like. In certain aspects, the user interface 106 may or may not be intended to be used or not be used by the subject and/or the user. The second predetermined temperature range includes a temperature range that is greater than the first predetermined temperature range. The user interface 106 may be configured to allow the user to input a greater and/or a lower temperature control of the hot air and the cold air than that which is included within the therapeutic range. In this manner, the user may be configured to override, via the user interface 106, the temperature control that is set or input by the subject. In other aspects, the user may be configured to modify, via the user interface 106, permissions to the first predetermined temperature range input by the subject. For example, the user may be configured to revoke, via the user interface 106, the first predetermined temperature range input by the subject via the user interface 106. In other aspects, the user may be configured to allow, via the user interface 106, the first predetermined temperature range to be input by the subject via the user interface 106.

Additionally or alternatively to restricting temperature control, the user interface 106 may be configured to restrict pressure control of the hot air and cold air for a first predetermined pressure range input by the subject. The first predetermined pressure range includes a therapeutic range. The therapeutic range may be preconfigured to allow pressure control for the hot air and the cold air to be automatically administered to the thermoelectric sequential compression device 120 worn by the subject without any oversight or intervention. In certain aspects, the therapeutic range may not be modified by the subject.

Further, the user interface 106 may be configured to restrict pressure control of the hot air and cold air for a second predetermined pressure range input by the user. The second predetermined pressure range includes a pressure range that is greater than the first predetermined pressure range. The user interface 106 may be configured to allow the user to provide a greater and/or a lower pressure control of the hot air and the cold air than that which is included within the therapeutic range. In this manner, the user may be configured to override, via the user interface 106, the pressure control that is input by the subject. In other aspects, the user may be configured to modify, via the user interface 106, permissions to the first predetermined pressure range input by the subject. For example, the user may be configured to revoke, via the user interface 106, the first predetermined pressure range input by the subject via the user interface 106. In other aspects, the user may be configured to allow, via the user interface 106, the first predetermined pressure range to be input by the subject via the user interface 106.

FIG. 6 may reference and incorporate any of the above constituent components and corresponding disclosure explained above with respect to FIGS. 1-5, such as the example integrated bed system including compression device of FIG. 1, the example thermoelectric sequential compression device of FIG. 2, the portion of the thermoelectric sequential compression device of FIG. 3, the example components of the integrated bed system of FIG. 4, and the example user interface of FIG. 5.

At block 605, the processor 102 independently controls a thermoelectric module 114 of a thermoelectric sequential compression device 120 to sequentially supply air to a respective inflatable bladder 112. The thermoelectric sequential compression device 120 may include a plurality of channels 116. The plurality of channels 116 may be fluidly coupled between a plurality of inflatable bladders 112 and a plurality of thermoelectric modules. The thermoelectric sequential compression device 120 may be communicatively coupled to the processor 102.

In certain aspects, the inflatable bladder 112 may comprise one of a plurality of inflatable bladders 112. The inflatable bladder 112 may be supplied with air so as to controllably inflate the inflatable bladder 112 to a predetermined pressure value at a predetermined temperature value. For example, the inflatable bladder 112 may be supplied with hot air and cold air from a blower, such as a blower 115, via the plurality of channels 116. The processor 102 may be configured to direct, such as via a user interface 106, the blower 115 to supply hot air and cold air to the inflatable bladder 112 via the plurality of channels 116.

At block 610, the processor 102 controls a blower 115 to supply a first predetermined amount of air at a first temperature value to a first inflatable bladder 112, and supply a second predetermined amount of air at a second temperature value to a second inflatable bladder 112.

At block 615, the processor 102 controls a fan 123 to exhaust air from a heat exhaust channel 117 of the thermoelectric sequential compression device 120. The heat exhaust channel 117 of the plurality of channels 116 may be configured to exhaust the hot air under a cooling mode operation. In addition, the thermoelectric module 114 may include a foam sheet 113 that is configured to condition air that is supplied to the plurality of channels 116. The thermoelectric sequential compression device 120 may be communicatively coupled to a fan 123.

At block 620, the processor 102 restricts, via a user interface 106, temperature and pressure control of hot air and cold air supplied to the respective inflatable bladder 112 based on a subject type. For example, depending on whether the subject type is a subject that is providing input, via the user interface, or whether the subject type is a user that is providing the input, via the user interface, such as the user interface 106, certain access and permissions may be controlled so as to input the temperature and pressure control of hot air and cold air supplied to a given inflatable bladder 112 via the blower 115.

The present disclosure relates to systems and methods for thermoelectric sequential compression devices utilizing thermoelectric technology to compensate for excessive heat generated while a subject wears the thermoelectric sequential compression device. Thermoelectric foam modules are incorporated in the thermoelectric sequential compression device fabric and inflatable bladder construction, and are configured to provide heating and cooling, thus delivering enhanced subject comfort. Moreover, the thermoelectric foam modules include temperature sensors allowing for optimal temperatures to be maintained, reducing the likelihood of pressure injuries. A plurality of thermoelectric foam modules may be included for zonal heating and cooling, one per inflatable bladder of the thermoelectric sequential compression device. In other aspects, a single thermoelectric foam module may be included in the thermoelectric sequential compression device for heating or cooling. By independently, and in certain aspects remotely, controlling the temperature and pressure amount of hot air and cold air supplied to any number of inflatable bladders via a user interface, monitoring and operational efficiency of the thermoelectric sequential compression device is improved and achieved in real-time. For example, a blower may be directed to provide any number of inflatable bladders with air in a sequential fashion promoting efficient blood circulation. Unlike conventional compression devices, the thermoelectric sequential compression devices disclosed herein can be integrated with a platform where the subject does not need to sit towards the end of a bed or require a separate overbed table. Because control of the temperature and pressure amount of the hot and cold air is not unrestricted, security and access permissions are particularly customized and implemented via the user interface based on a user type for thermoelectric sequential compression device operation control, including controlled administration of a therapeutic temperature and pressure operation control.
