DETAILED DESCRIPTION

The present disclosure will be further described below with reference to the drawings and embodiments.

The First Embodiment

Referring to FIGS. 1 to 4, the pneumatic physiotherapy apparatus with a unique structure includes a wrap 1 and a controller 2. The wrap 1 includes at least an outer wrap (such as an upper outer wrap 11 and a lower outer wrap 12), an inner component housing 3, and an inner air bladder set 4; the controller 2 is fixed to the wrap 1 and connected to the inner component housing 3 to operate the components inside the inner component housing 3; the inner component housing 3 contains components of an inflation motor 31 and an integrated control board 32 that are electrically powered by the battery 33 inside the inner component housing 3 or by a battery bank/AC adapter outside the inner component housing 3; the inner air bladder set 4 includes one or more than one air bladders that are inflatable. The inflation motor 31 that is controlled by the integrated control board 32 inflates the inner air bladder set 4. There is no outer component housing.

Specifically, the inner component housing 3 is arranged inside the wrap 1. The inner component housing 3 contains most or all components needed for a pneumatic physiotherapy apparatus, and is hidden inside the wrap 1. The inner component housing 3 is hidden inside the wrap 1, such that it cannot be seen from outside the apparatus. Therefore, the exposed controller 2 connected to the inner component housing 3 becomes attractive.

The inner component housing hidden inside the wrap 1 is not small. Instead, the exposed controller is outside the wrap 1 and is small, compared to the inner component housing.

In order to detect and control the air pressure, the inner component housing 3 also contains a solenoid valve 34 and a pressure detection valve 35. The solenoid valve 34, pressure detection valve 35, and the inflation motor 31 are electrically connected to the integrated control board 32. When the inflation pressure inside the air bladder set 4 reaches a preset value, the pressure detection valve 35 detects and sends signals to the integrated control board 32. After receiving signals, the integrated control board 32 will stop the inflation motor 31. After the inflation motor 31 stops, the air bladder set 4 will immediately deflate, or maintain a preset pressure for a certain period of time prior to deflation.

In order to avoid the safety concern caused from the excessive pressure in the air bladder set 4, a pressure protection valve 36 can be equipped in the inner component housing 3. When the pressure inside the air bladder set 4 is excessive and beyond an allowable pressure range, the pressure protection valve 36 will be activated, and the excessive pressure will release from the air bladder set 4.

The excessive pressure level varies. For example, if the maximum preset pressure is 50 mmHg, any pressure higher than 50 mmHg and its tolerance will be excessive. If the maximum preset pressure is 120 mmHg, any pressure higher than 120 mmHg and its tolerance will be excessive.

In addition, the inner component housing 3 also contains several screw posts and/or buckle grooves 37. The inner component housing 3 is fixedly connected to the controller 2 through the screw posts and/or buckle grooves 37 to form an integrally fixed connection between the controller 2 and the inner component housing 3. The inner component housing 3 also includes a first housing 38 and a second housing 39; the first housing 38 and the second housing 39 are fixedly connected to each other, and form a cavity. The cavity is used to load the components including the inflation motor 31, the integrated control board 32, the battery 33, the solenoid valve 34, the pressure detection valve 35, and the pressure protection valve 36. One or more than one connection tubing 30 and wiring may be needed to make connection between the above components.

For ease of use, a single or multiple control button 21 is provided on the front or side of the controller 2; the control button 21 can be a convex button(s), a concave button(s), a flat button(s), or a touch button(s). The user can use the control button 21 on the controller 2 to operate the pneumatic physiotherapy apparatus with a unique structure of this disclosure. A display indication 22 is arranged on the front or side of the controller 2; the display indication 22 can be a digital display, an LCD display screen, or a light indicator(s). The user can observe the working state of the controller 2 through the display indication 22 when in use. In addition, a charging port 23 is provided on the front or side of the controller 2, and used to charge the battery 33 in the inner component housing 3.

The wrap 1 can be used to cover different treatment areas, including calf, foot, leg, arm, buttock, waist, or other body areas. The wrap 1 in this first embodiment is for the body area of calf, and is used as an example for description. In use, a user wears the wrap 1 on the calf via the Velcro 13, and simply operates the controller 2 to achieve a preset pressure compression for compression treatment. This disclosure of a pneumatic physiotherapy apparatus has the characteristics of simple and reasonable structure, excellent performance, convenient use, reliable comfort, and strong practicability. Therefore, the user can use this disclosure to enhance use experience, improve blood circulation, relieve pain, prevent deep vein thrombosis, and treat lymphedema and other diseases.

The disclosure improves blood flow or circulation, and relieves pain, because the disclosure is a type of powered inflatable tube device, which “is a powered device intended for medical purposes, such as to relieve minor muscle aches and pains and to increase circulation. It simulates kneading and stroking of tissues with the hands by use of an inflatable pressure cuff.”

Lymphedema has no known cure in modern medicine, and one potential symptom of lymphedema is that “[t]ime of venous outflow period of blood flow pulse was lower in lymphedema-affected arms than in healthy normal or lymphedema nonaffected arms.” From the journal “Lymphatic research and biology”, article “Segmental Blood Flow and Hemodynamic State of Lymphedematous and Nonlymphedematous Arms”, section “Methods and Results”, March 2011.

Therefore, by utilizing the present disclosure, a user could increase blood flow to their arms, and thus counteract the lymphedema-caused low blood flow. Regular blood flow may ease the pain that a user feels in his/her arms, and may help the user perform regular activities in a better manner than with low blood flow.

“Accesses that show a large (>15%) decrement in vascular access blood flow are associated with a high risk of thrombosis. Serial measurements of vascular access blood flow predict access thrombosis.” From the journal “Kidney International”, article “Change in access blood flow over time predicts vascular access thrombosis”, November 1998.

Therefore, a user who utilizes the present disclosure can improve their blood flow, and help to prevent thrombosis.

In order for the user to view the usage data of the pneumatic physiotherapy apparatus with a unique structure, the front or side of the controller 2 is alternatively or additionally provided with a USB interface. The controller 2 can connect to the data cable and the computer through the USB interface to read the usage data. In an alternative embodiment, a memory card can be alternatively or additionally provided on the front or side of the controller 2. When the memory card is plugged into the front or side of the controller 2, the memory card can record the usage data of the pneumatic physiotherapy apparatus with a unique structure. In another alternative embodiment, the controller 2 or the inner component housing 3 is alternatively or additionally equipped with a Bluetooth module, and the user can wirelessly connect a smart device (such as a smart phone) to the Bluetooth module to read the usage data of the pneumatic physiotherapy apparatus with a unique structure.

Alternatively or additionally, the usage data can then be analyzed through artificial intelligence in order to determine optimal patterns for using the pneumatic physiotherapy apparatus with a unique structure. For example, perhaps a user prefers using the apparatus in a certain rhythm, then the artificial intelligence can learn that rhythm and utilize it again in case the person forgets, or perhaps use the rhythm on a different person in order to determine whether the new person enjoys the same rhythm as the original person. Instead of a rhythm, the artificial intelligence might also learn a certain series of buttons that the user likes being pushed, and this pattern could be remembered and shared by the artificial intelligence. Another possibility is that the artificial intelligence could analyze the usage data and could determine certain body parts that a person likes to use the apparatus on. Another possibility is that the artificial intelligence could analyze the usage data and could determine the optimal amount of time that a user wants the apparatus on particular body parts. It's also possible that the usage of data could be analyzed by experts in the field, and they could provide recommendations.

Some optional alternatives to artificial intelligence are machine learning, deep learning, and neural networks, each of which could fulfill the same functions as listed above.

To improve the air bladder deflated speed, Refer to FIGS. 22-25, the inner component housing 3 also includes an air filling tubing 310, and a plurality of three-way solenoid valves 341; wherein the inflation motor 31, the plurality of three-way solenoid valves 341 are controlled by the integrated control board 32; wherein the inner air bladder set 4 includes a multiple sets of air bladders 41, the multiple sets of air bladders 41 are equipped with flow nozzles 42; an air outlet of the inflation motor 31 is connected with an air inlet of the air filling tubing 310, a first end 3411 of each three-way solenoid valve 341 is connected with an air outlet of the air filling tubing 310, and a second end 3412 of each three-way solenoid valve 341 is connected with the flow nozzle 42 of the air bladder 41.

When the three-way solenoid valve 341 is powered on, the first end 3411 of the three-way solenoid valve 341 and the second end 3412 of the three-way solenoid valve 341 are connected, and the inflation motor 31 inflates the air bladder 41; when the three-way solenoid valve 341 is powered off, the second end 3412 of the three-way solenoid valve 341 and a third end 3413 of the three-way solenoid valve 341 are connected, and the air bladder 41 is deflated.

It should be noted that the number of air bladders 41 is two or more. Referring to FIGS. 19 and 20, there are four air bladders 41 arranged on the wrap 1.

After using the above Settings, when inflating, the inflation motor 31 is opened, the corresponding three-way solenoid valve 341 is powered on, the channel of the first end 3411 of the three-way solenoid valve 341 and the second end 3412 of the three-way solenoid valve 341 is opened, the channel of the second end 3412 of the three-way solenoid valve 341 and the third end 3413 of the three-way solenoid valve 341 is closed, the air bladder 41 is inflated; when the air is deflated, the inflation motor 31 is closed, the corresponding three-way solenoid valve 341 is powered off, the channel of the second end 3412 of the three-way solenoid valve 341 and the third end 3413 of the three-way solenoid valve 341 is open, the channel of the first end 3411 of the three-way solenoid valve 341 and the second end 3412 of the three-way solenoid valve 341 is closed, the air bladder 41 is deflated. Because each air bladder 41 has an independent deflated channel, so as to improve the air bladder 41 deflated speed.

Referring to FIGS. 22, there are a connection tubing 30 between the flow nozzle 42 and the inflation motor 31; wherein the flow nozzle 42 is connected to the second end 3412 of the three-way solenoid valve 341 through the connection tubing 30; wherein the inflation motor 31 generates the air flow; wherein the air flow from the inflation motor 31 enters the air bladder 41 through the air filling tubing 310, the three-way solenoid valve 341, the connection tubing 30, and the flow nozzle 42. The air inlet of each connection tubing 30 is connected to the second end 3412 of the three-way solenoid valve 341, and the air outlet of each connection tubing 30 is connected to an air bladder 41. The connection tubing 30 is connected to the air filling tubing 310 through the three-way solenoid valve 341, so as to facilitate the control of the inflating of the air bladder 41.

Referring to FIGS. 24 and 25, the three-way solenoid valve 341 also includes a one-way valve 342, the one-way valve 342 is arranged at the first end 3411 of the three-way solenoid valve 341, the one-way valve 342 allows the air flow in the air filling tubing 310 to pass through. Thus, avoiding the increase of the volume of the three-way solenoid valve 341 and saving the space required for the installation of the three-way solenoid valve 341. Through the setting of the one-way valve 342, the one-way valve 342 allows the air flow in the air filling tubing 310 to pass through, so that the air flow can only flow through the first end 3411 to the second end 3412 and enter the air bladder 41. The air flow in the air bladder 41 will not flow out through the second end 3412 to the first end 3411, and at the same time, the air flow in the air bladder 41 will not flow back to the other air bladder 41 with lower pressure values, so as to achieve the effect of pressure retaining. Thus, after the pressure in the first inflated air bladder 41 reaches the preset value, the second three-way solenoid valve 341 will be opened to inflate the second air bladder 41. At the same time, the air flow in the first air bladder 41 will not flow to the second air bladder 41, wherein the one-way valve 342 is made of silicone material and is in a closed state under normal conditions. During inflation, the inflation motor 31 has a certain pressure, so the one-way valve 342 will be rushed out.

Referring to FIGS. 24, when inflating, the inflation motor 31 is opened, according to the inflating mode, the corresponding three-way solenoid valve 341 is powered on, the channel of the first end 3411 and the second end 3412 is opened, and the movable valve 343 blocks the channel of the third end 3413, so that the channel of the second end 3412 and the third end 3413 is closed, and the air bladder 41 is inflated.

Referring to FIGS. 25, when the air is deflated, the inflation motor 31 is closed, according to the deflated mode, the corresponding three-way solenoid valve 341 is powered off, the channel of the third end 3413 and the second end 3412 is opened, and the movable valve 343 blocks the channel of the first end 3411, so that the channel of the first end 3411 and the second end 3412 is closed, and the air bladder 41 is deflated. Because each air bladder 41 has an independent deflated channel, so as to improve the air bladder 41 deflated speed.

Referring to FIGS. 24 and 25, usually in the process of using the two-way solenoid valve, if the user accidentally presses the inflating air bladder 41, the equipment will judge that the pressure in the air bladder 41 has reached the set value, and will close the two-way solenoid valve so that the air bladder 41 stops inflating, resulting in a small air volume in the air bladder 41, and the actual pressure in the air bladder 41 does not reach the set value. It is necessary to wait for all air bladders 41 to be filled for a cycle before the underfilled air bladders 41 can be filled normally in the next cycle. However, the three-way solenoid valve 341 is selected in the present disclosure. Even if the problem of two-way solenoid valve occurs, when the next air bladder 41 is filled, the previously unfilled air bladder 41 will be filled together, which solves the problem of waiting for the next cycle to be filled, and improves the user's experience.

The Twenty-Seventh Embodiment

Referring to FIGS. 10 to 15 and 21, the pneumatic therapy apparatus and method includes a wrap and a controller 1501. The wrap includes an outer wrap 1002 and an inner air bladder set 1003; the controller 1501 is fixedly connected to (or integrally fixed on) the outer wrap 1002; the inner air bladder set 1003 contains a first air bladder 1105 and a second air bladder 1106 that are overlapped; the controller 1501 contains an inflation motor 1007 and an integrated control board 1022 that are electrically powered by a single battery or multiple batteries inside the controller 1501 or by a battery bank/AC adapter/power supply outside the controller 1501. The inflation motor 1007 that is controlled by the integrated control board 1022 inflates the second air bladder 1106 first, and then inflates the first air bladder 1105 to realize the overlapped compression between the second air bladder 1106 and the first air bladder 1105.

Specifically, the size of the first air bladder 1105 is larger than that of the second air bladder 1106, and the second air bladder 1106 is located outside the lower section of the first air bladder 1105 (FIG. 11). The boundary of the first air bladder 1105 is seal welded with one or more than one air flow hole 1110 on its lower section; the boundary of the second air bladder 1106 is seal welded on the lower section of the first air bladder 1105, making the second air bladder 1106 cover the air flow hole 1110 on the first air bladder 1105. There is a flow nozzle 1109 on the second air bladder 1106 for the inflation motor 1007 to inflate the second air bladder 1106 first and then the first air bladder 1105. The air flow hole 1110 on the lower section of the first air bladder 1105 creates one or more than one air flow passageway between the first air bladder 1105 and the second air bladder 1106. Through the one or more than one air flow passageway, the air flow enters from the second air bladder 1106 to the first air bladder 1105 to achieve overlapped compression between the first air bladder 1105 and the second air bladder 1106.

It is easy and practical to make the inner air bladder set 1003, which includes a bottom layer 1231 of the first air bladder 1105, a top layer 1232 of the first air bladder 1105, and a top layer 1233 of the second air bladder (FIG. 12). First, the flow nozzle 1109 is sealed welded on the top layer 1233 of the second air bladder 1106. Second, the air flow hole 1110 is made on the lower section of the top layer 1232 of the first air bladder 1105, and the optional nozzle 1112 is sealed welded on the upper section of the top layer 1232 of the first air bladder 1105. Third, the boundary of the second air bladder 1106 is seal welded onto the lower section of the top layer 1232 of the first air bladder 1105. Fourth, the boundary of the top layer 1232 of the first air bladder 1105 is sealed welded to the boundary of a bottom layer 1231 of the first air bladder 1105.

The inner air bladder set 1003 in FIGS. 11 and 12 represents one set of the first air bladder 1105 and the second air bladder 1106 overlapped. To cover the large body areas (such as the full leg and the full arm), it will require a large inner air bladder set 1003 with more than one set of the first air bladder 1105 and the second air bladder 1106 overlapped. FIGS. 13 and 14 and 21 represents such a large inner air bladder set 1003 with two and four sets of the first air bladder 1105 and the second air bladder 1106 overlapped, respectively. 1105′, 1105″, 1105′″, and 1105″″ represents the first air bladder in the first, second, third, and fourth sets, respectively; 1106′, 1106″, 1106′″, and 1106″″ represents the second air bladder in the first, second, third, and fourth sets, respectively; 1109′, 1109″, 1109′″, and 1109″″ represents the flow nozzle on the second air bladder in the first, second, third, and fourth sets, respectively; 1110′, 1110″, 1110′″, and 1110″″ represents the air flow hole on the first air bladder in the first, second, third, and fourth sets, respectively; 1112′, 1112″, 1112′″, and 1112″″ represents the optional nozzle on the first air bladder in the first, second, third, and fourth sets, respectively. Similarly, it can extend to any sets (such as eight sets) of the first air bladder 1105 and the second air bladder 1106 overlapped, if needed.

There is a first connection tubing 1013 between the flow nozzle 1109 and the inflation motor 1007. The flow nozzle 1109 on the second air bladder 1106 is connected to the inflation motor 1007 through the first connection tubing 1013. The inflation motor 1007 controlled by the integrated control board 1022 generates air flow. The air flow from the inflation motor 1007 enters the second air bladder 1106 through the first connection tubing 1013 and the flow nozzle 1109. When the air pressure in the second air bladder 1106 rises to a certain level, the air flow starts to enter the first air bladder 1105 from the second air bladder 1106 through the air flow passageway.

In order to detect and control the air pressure inside the first air bladder 1105 and the second air bladder 1106, the controller 1501 also contains a solenoid valve 1008 and a pressure detection valve 1011. The solenoid valve 1008, the pressure detection valve 1011, and the inflation motor 1007 are electrically connected to the integrated control board 1022. The first air bladder 1105 includes an optional nozzle 1112 on its upper section. The optional nozzle 1112 not only can release the pressure from the first air bladder 1105 and the second air bladder 1106, but also control the pressure of the first air bladder 1105 and the second air bladder 1106 via the pressure detection valve 1011. If the first air bladder does not include the optional nozzle 1112, the flow nozzle 1109 on the second air bladder 1106 will be used to release the pressure from the first air bladder 1105 and the second air bladder 1106, and to control the pressure of the first air bladder 1105 and the second air bladder 1106 via the pressure detection valve 1011.

There are a second connection tubing 1026 between the optional nozzle 1112 and the pressure detection valve 1011. The optional nozzle 1112 is connected to the pressure detection nozzle 1011 and the solenoid valve 1008 via the second connection tubing 1026. When the inflation pressure inside the first air bladder 1105 and the second air bladder 1106 reaches the preset value, the pressure detection valve 1011 detects and sends signals to the integrated control board 1022. After receiving signals, the integrated control board 1022 will stop the inflation motor 1007. After the inflation motor 1007 stops, the first air bladder 1105 and the second air bladder 1106 will maintain the preset pressure for a certain period of time prior to deflation, or immediately deflate through the optional nozzle 1112, the second connection tubing 1026, and the solenoid valve 1008 in sequence.

In order to avoid the safety concern caused from the excessive pressure in the first air bladder 1105 and the second air bladder 1106, a pressure protection valve 1025 is equipped in the controller 1501. The pressure protection valve 1025 is connected to a multiple-way connector 1024. When the pressure inside the first air bladder 1105 and the second air bladder 1106 is excessive and beyond an allowable pressure range, the pressure protection valve 1025 will be activated, and the excessive pressure will be released from the first air bladder 1105 and the second air bladder 1106.

During operation, the inflation motor 1007 and the pressure protection valve 1025 are connected to the multiple-way connector 1024, which is connected to the flow nozzle 1109. The inflation motor 1007 controlled by the integrated control board 1022 first inflates the second air bladder 1106, and then enters the first air bladder 1105 from the second air bladder 1106 through the air flow passageway. This method of inflation achieves an overlapped compression between the first air bladder 1105 and the second air bladder 1106, and effectively avoids blind spots and shortcomings in the prior art. Therefore, users can use the pneumatic therapy apparatus and method of this disclosure to promote blood flow, treat lymphedema, prevent deep vein thrombosis and other diseases, and improve user experience in the treatment areas (such as limbs).

The controller 1501 also includes a first housing 1019 and a second housing 1020; the first housing 1019 and the second housing 1020 are fixedly connected to each other, and form a cavity 1021 between the two housings. The cavity 1021 covers the inflation motor 1007, the solenoid valve 1008, the pressure detection valve 1011, the multiple-way connector 1024, the pressure protection valve 1025, the integrated control board 1022, and the battery 1023.

For ease of use, a single or multiple control button 1015 is on the front or side of the controller 1501. The control button 1015 can be shaped in many different ways, such as a convex button, a concave button, a flat button, or a touch button. The user can use the control button 1015 to operate the pneumatic therapy apparatus and method.

A display indication 1016 is arranged on the front or side of the controller 1501. The display indication 1016 can be a digital display, an LCD display screen, or a light indicator. The user can observe the working state of the controller 1501 through the display indication 1016 when in use.

The first connection tubing 1013 and the second connection tubing 1026 in this twenty-seventh embodiment are inside the wrap. The wrap can be used to cover different treatment areas, including the leg, arm, buttock, waist, or a combination of the above. The wrap in this embodiment is for any limb, and is used as an example for description. In use, a user wears the wrap on the limb, and operates the controller 1501 to achieve an overlapped compression between the first air bladder 1105 and the second air bladder 1106. Therefore, this disclosure of a pneumatic therapy apparatus and method can promote blood flow, treat lymphedema, and help prevent deep vein thrombosis and other diseases.

In this twenty-seventh embodiment, the connection between the controller 1501 and the wrap is fixedly connected (or integrally fixed) to each other. Specifically, a connecting bracket 1004 is fixedly arranged inside the outer wrap 1002. The connecting bracket 1004 contains several screw posts and/or buckle grooves 1018, and is fixedly connected to the controller 1501 through the screw posts, buckle grooves 1018, and/or screws 1028 to form an integrally fixed connection between the controller 1501 and the wrap.

In order for the user to charge the built-in battery inside the controller 1501 or provide the power supply to the controller 1501, there is a charging/power port 1027 on the controller. In addition, this port 1027 can be also used to transfer and view the usage data of the pneumatic therapy apparatus and method.

In an alternative embodiment, a memory card can be alternatively or additionally provided on the front or side of the controller 1501. When the memory card is plugged into the front or side of the controller 1501, the memory card can record the usage data of the pneumatic therapy apparatus and method for the user to read.
