Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a traditional Chinese medicine heat permeation air pressure therapy device. Background Technology

[0002] Pneumatic compression therapy, also known as air wave pressure therapy or circulatory pressure therapy system, is a medical device that promotes blood circulation and lymphatic drainage by periodically pressurizing and relaxing an inflatable airbag. It can accelerate venous blood flow in the lower limbs, reduce blood stasis, and decrease the risk of thrombosis. It can also promote lymphatic drainage, alleviating edema caused by trauma, surgery, or chronic diseases. Furthermore, pneumatic compression therapy can effectively prevent muscle atrophy and joint stiffness caused by prolonged bed rest.

[0003] In existing technologies, to improve treatment effectiveness, the patient's skin surface is heated during pneumatic therapy to accelerate blood circulation and lymphatic drainage. For example, a patent application with application number CN202320429473.8 discloses a heatable pneumatic therapy device, comprising multiple independent airbags, each connected to an air pump by a rubber inflation tube, and an outer canvas strap. The multiple independent airbags are arranged side by side and are all wrapped inside the outer canvas strap, and each independent airbag can be connected end to end to form a ring. The outer canvas strap helps the airbags fit better against the human limb, reducing the required air pressure while improving the squeezing and massage effect. A heating element is provided on the inflation tube to increase the airflow temperature using electric heating, bringing a heat therapy effect to the pneumatic therapy device.

[0004] Although the above structure can achieve simultaneous treatment with air pressure and heat, this device cannot sequentially inflate from the distal to the proximal end of the limb through multi-chamber airbags, and cannot simulate muscle contraction and relaxation, thus limiting its therapeutic effect. Moreover, this device has a single function, only improving blood circulation through mechanical pressure, lacking the synergistic effect of drug penetration, and has limited therapeutic effect on the early rehabilitation of patients with chronic diseases (such as arthritis, muscle strain, and lower limb dysfunction) and critical illnesses.

[0005] In summary, a pneumatic therapy device that can be sequentially inflated and has versatility needs to be designed to solve the problems existing in the current technology. Utility Model Content

[0006] To address the issues of existing pneumatic therapy devices being unable to inflate sequentially and having limited functionality, this application provides a traditional Chinese medicine heat permeation pneumatic therapy device, employing the following technical solution:

[0007] A traditional Chinese medicine heat permeation air pressure therapy device includes a binding belt, an air pressure component equidistantly installed on the binding belt, a medicine storage bag installed on the inner side wall of the right section of the binding belt, and a heater installed on the outer side wall of the right section of the binding belt. The heater is located directly behind the medicine storage bag, and the air pressure component is located to the left of the heater and the medicine storage bag. An air supply pipe is also connected to the bottom of the air pressure component, and multiple permeation ports are equidistantly opened on the medicine storage bag.

[0008] Furthermore, the restraint strap also includes a pair of connecting fleece surfaces installed on the outer side wall of the restraint strap and a pair of connecting hook surfaces installed on the inner side wall of the restraint strap. The connecting fleece surfaces are located at the upper and lower ends of the restraint strap, respectively, and the connecting hook surfaces are located at the upper left and lower left ends of the restraint strap, respectively. The positions of the connecting fleece surfaces and the connecting hook surfaces correspond to each other.

[0009] Furthermore, the pneumatic assembly includes airbags equidistantly mounted on the restraint strap, an air supply channel connected to the bottom of the airbag, and an exhaust channel located on the right side of the airbag. The lower end of the air supply channel is also connected to the top of the next airbag, and the lowermost air supply channel is connected to the air supply pipe. The exhaust channel is installed inside the restraint strap and its lower end is open.

[0010] Furthermore, the air pressure assembly also includes an on / off valve installed between the airbag and the exhaust channel, an air pressure detector installed on the airbag, a piston that is movably locked between the airbag and the air supply channel, and a spring that is movably sleeved on the piston. The air pressure detector is installed on the uppermost airbag.

[0011] Furthermore, the piston includes an upper locking block, a connecting post connected to the lower end of the upper locking block, a chassis connected to the lower end of the connecting post, and a venting groove formed on the connecting post. The lower end of the venting groove also extends through the chassis. The upper locking block is movably locked inside the air bladder, the chassis is movably locked inside the air supply channel, and the spring is located inside the air supply channel.

[0012] In summary, this application has the following beneficial effects:

[0013] 1. The device of this application can inflate and pressurize the airbag sequentially from bottom to top. By using a continuously input external air pump in conjunction with a moving piston, gas can be sequentially introduced into the airbag from bottom to top through the ventilation slot. The sequential inflation and pressurization can simulate the contraction and relaxation of muscles, thereby improving the therapeutic effect.

[0014] 2. The device of this application can intermittently and cyclically pressurize. When the pressure detector detects that the pressure of the uppermost airbag reaches a certain value, the on-off valve opens for a certain period of time and exhausts gas. After the on-off valve exhausts gas, it closes. The continuously input gas can re-inflate and pressurize the airbag. This cycle is repeated to improve the treatment effect.

[0015] 3. This application is versatile. The heat generated by the heater can help the herbal ingredients in the medicine storage bag to better penetrate into the deep layers of the patient's skin. Moreover, the air pressure component, heater and medicine storage bag are used together to not only promote blood circulation through mechanical pressure, but also to achieve comprehensive treatment by utilizing the synergistic effect of drug penetration and heat therapy. It can be used to treat a variety of diseases. Attached Figure Description

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0024] A traditional Chinese medicine heat permeation air pressure therapy device includes a binding belt 1, an air pressure component 2 equidistantly installed on the binding belt 1, a medicine storage bag 4 installed on the inner side wall of the right section of the binding belt 1, and a heater 3 installed on the outer side wall of the right section of the binding belt 1. The heater 3 is located directly behind the medicine storage bag 4, and the air pressure component 2 is located to the left of the heater 3 and the medicine storage bag 4. An air supply pipe 5 is also connected to the bottom of the air pressure component 2. The medicine storage bag 4 is also provided with multiple permeation ports 41 equidistantly.

[0025] The restraint strap 1 also includes a pair of connecting fleece surfaces 11 installed on the outer side wall of the restraint strap 1 and a pair of connecting hook surfaces 12 installed on the inner side wall of the restraint strap 1. The connecting fleece surfaces 11 are located at the upper and lower ends of the restraint strap 1, respectively, and the connecting hook surfaces 12 are located at the upper left and lower left ends of the restraint strap 1, respectively. The positions of the connecting fleece surfaces 11 and the connecting hook surfaces 12 correspond to each other.

[0026] The pneumatic assembly 2 includes airbags 21 equidistantly mounted on the restraint strap 1, an air supply channel 22 connected to the bottom of the airbags 21, and an exhaust channel 23 located on the right side of the airbags 21. The lower end of the air supply channel 22 is also connected to the top of the next airbag 21, and the lowermost air supply channel 22 is connected to the air supply pipe 5. The exhaust channel 23 is installed inside the restraint strap 1 and its lower end is open. The pneumatic assembly 2 also includes an on / off valve 26 installed between the airbags 21 and the exhaust channel 23, a pressure detector 27 installed on the airbags 21, a piston 24 movably engaged between the airbags 21 and the air supply channel 22, and a spring 25 movably sleeved on the piston 24. The pressure detector 27 is installed on the uppermost airbag 21. The piston 24 includes an upper locking block 242, a connecting post 243 connected to the lower end of the upper locking block 242, a chassis 244 connected to the lower end of the connecting post 243, and a venting groove 241 that passes through the chassis 244 and is formed on the connecting post 243. The lower end of the venting groove 241 also passes through the chassis 244. The chassis 244 is movably locked in the air supply channel 22, and the spring 25 is located in the air supply channel 22.

[0027] The implementation principle of this application is as follows: In use, the herbal medicine pack required for the patient's treatment is first laid flat inside the medicine storage bag 4. Then, the medicine storage bag 4 is fitted against the patient's skin, and the restraint strap 1 is wrapped around the patient's limb. After wrapping, the connecting hook surface 12 is attached to the connecting felt surface 11, thereby limiting the restraint strap 1 to the patient's limb. Next, the device is connected to electricity, and the gas supply pipe 5 is connected to an external air pump. The external air pump inflates the air pressure assembly 2 through the gas supply pipe 5. This external air pump is existing technology and only needs to perform the inflation function; details are not elaborated here. When the gas passes through the lowest gas supply channel 22, under the continuous action of air pressure, the piston 24 moves upward, and the ventilation groove 241 connects to the gas supply channel 22 and the air... Gas continuously enters the lowest airbag 21 through the ventilation channel 241, causing the airbag 21 to inflate and compress the patient's muscles. When the air pressure in the lowest airbag 21 reaches a certain level and gas continues to be supplied, the increasing air pressure pushes the piston 24 between the lowest and upper airbags 21, causing the piston 24 to move upwards, thus connecting the lowest and upper airbags 21. Gas then passes through the lower airbag 21 and inflates the upper airbag 21. During this process, to ensure that the lowest and upper airbags 21 remain connected, the gas flow rate into the lowest airbag 21 equals its gas flow rate. This continues until the second airbag 21 is inflated. The continuously supplied gas continues to inflate and pressurize the uppermost airbag 21. The sequential inflation design, from far to near, simulates muscle contraction and relaxation, promoting blood and lymphatic return, reducing blood stasis, and improving treatment effectiveness. Simultaneously, the pressure detector 27 monitors the pressure inside the uppermost airbag 21 in real time. When the pressure in the uppermost airbag 21 reaches a certain value, all three on / off valves 26 open simultaneously for a period of time. During this period, the external air pump continuously supplies gas, and the gas inside the airbag 21 is discharged from the device through the exhaust channel 23. During the exhaust process, due to the decrease in pressure inside the airbag 21, the piston 24 moves downward under the action of the spring 25, and the ventilation slot 241 retracts into the air supply channel 22, locking the upper part of the airbag. Block 242 is locked at the bottom of the airbag 21, cutting off the inflation channel; after the on / off valve 26 is closed, the continuously operating external air pump re-inflates and pressurizes the airbag 21 in sequence. This cycle can intermittently promote the patient's blood circulation and lymphatic return, improving the treatment effect. During this process, the exhaust flow of the on / off valve 26 is much greater than the inflation flow of the external air pump, thus achieving indirect pressurization. While intermittently pressurizing, the medicine storage bag 4 encased in the air pressure component 2 and the heater 3 work together to further improve the treatment effect. The heat generated by the heater 3 can help the herbal ingredients in the medicine storage bag 4 to better penetrate into the patient's skin, and the penetration port 41 on the medicine storage bag 4 also helps with penetration.Therefore, it can be seen that the pneumatic component 2, heater 3 and medicine storage bag 4, when used together, can not only promote blood circulation through mechanical pressure, but also achieve comprehensive treatment by utilizing the synergistic effect of drug penetration and thermotherapy. It can be used to treat a variety of diseases and has versatility.

[0028] In addition, the air pressure detector 27, on / off valve 26 and heater 3 used in the device of this application are all existing technologies, and the corresponding control methods are also existing technologies. They can achieve the corresponding functions, and the specific principles will not be elaborated in this technical solution.
