Technical Field

[0001] This utility model relates to the technical field of medical anti-bedsore products, specifically a pneumatic leg sleeve for varicose veins. Background Technology

[0002] The structure of the patented CN213251034U is similar to that of the pneumatic leg sleeves for varicose veins commonly found on the market. These are disposable designs that slip on the legs from the feet upwards, similar to stockings. Size adjustments are required uniformly, and the length is generally not adjustable. This presents several problems in use: 1. When using pneumatic leg sleeves for varicose veins, the size needs to be adjusted to ensure proper coverage for different body types. Because the one-piece design generally requires uniform size adjustments, it can easily lead to a situation where the sleeves are too tight on thicker areas and too loose on thinner areas, resulting in lower treatment effectiveness and poor versatility. Utility Model Content

[0003] The purpose of this invention is to provide a pneumatic leg sleeve for varicose veins to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic leg sleeve for varicose veins, comprising a first part for wearing on one side of the leg and a second part for wearing on the other side of the leg; the first part and the second part have the same structure, and the first part is provided with an air bladder, the air inlet tube of the air bladder passing through the mounting cavity provided on the first part and connected to the provided air nozzle; both ends of the first part are provided with mounting grooves, and rubber strips are provided in the mounting grooves, and are installed on the facing surfaces of the first part and the second part through the rubber strips, so that the first part and the second part are worn on the user's leg; the number of air bladders is multiple, and the multiple air bladders are distributed on the inner wall surface of the first part or the second part.

[0005] As a preferred technical solution of this utility model: the cross-section of the airbag is elliptical, and the width of the airbag is greater than the width of the first part.

[0006] As a preferred technical solution of this utility model: the cross-section of the rubber strip is "I" shaped, and the rubber strip is a thermoplastic elastomer.

[0007] As a preferred technical solution of this utility model: the air nozzle includes a housing and a pressure cap movably connected to the housing. A through hole is provided on the bottom surface of the housing, and a spring and a valve disc are provided inside the housing. One side of the spring abuts against the inner bottom surface of the housing, and the other side of the spring causes the valve disc to press against the pressure cap. An avoidance groove is also provided on the circumferential surface of the valve disc. The valve disc slides with a guide hole provided in the pressure cap through a guide rod, and an exhaust groove is also provided on the inner wall surface of the guide hole.

[0008] As a preferred technical solution of this utility model: one side of the pressure cap is threaded to the inner wall of the outer shell through an external threaded portion, and the external threaded portion is also provided with a stop portion, which is in contact with the valve disc.

[0009] As a preferred technical solution of this utility model: the inner wall surface of the outer shell is further provided with a limiting pin, and one end of the limiting pin passes through the limiting pin and fits against the valve disc.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0022] Please see Figure 1-7 This utility model provides an embodiment of a pneumatic leg sleeve for varicose veins, comprising a first part 1 for wearing on one side of the leg and a second part 2 for wearing on the other side of the leg; the first part 1 and the second part 2 have the same structure, and the first part 1 is provided with an airbag 5, the air inlet tube 7 of the airbag 5 passes through the mounting cavity 8 provided on the first part 1 and is connected to the provided air nozzle 3; both ends of the first part 1 are provided with mounting grooves 6, and the mounting grooves 6 are provided with rubber strips 4, which are installed on the facing surfaces of the first part 1 and the second part 2 so that the first part 1 and the second part 2 are worn on the user's leg; the number of airbags 5 is multiple, and the multiple airbags 5 are distributed on the inner wall surface of the first part 1 or the second part 2.

[0023] In summary, after the first part 1 and the second part 2 are placed on the user's leg, the rubber strip 4 is inserted into the mounting slot 6 to fix the two parts to the affected area on the patient's leg. Once the two parts are fixed to the affected area, external air is injected into the airbag 5 through the air nozzle 3. The expansion of the airbag 5 and the tension of the rubber strip 4 are used to make the two parts tightly hug the affected area. Since there are multiple airbags 5, and each airbag 5 has an independent air nozzle 3, the air pressure of each airbag 5 can be freely adjusted. Based on this, the cooperation between the rubber strip 4 and the airbag 5 allows the gap between the two parts to be freely adjusted. In particular, the pressure of the airbag 5 can be independently controlled, thus further enhancing the versatility of the device.

[0024] In addition, multiple first parts 1 and second parts 2 can be stacked upwards along the leg as needed, thus allowing the device to adapt to the length of the affected area.

[0025] Furthermore, since the cross-section of the airbag 5 is elliptical and the width of the airbag 5 is greater than the width of the first part 1, the airbag 5 has a larger contact area with the user's leg.

[0026] In addition, since the cross-section of the rubber strip 4 is "I" shaped and the rubber strip 4 is a thermoplastic elastomer, the rubber strip 4 can reliably connect the two parts while also facilitating the installation and replacement of the rubber strip 4.

[0027] Based on the above scheme, the air nozzle 3 includes a housing 30 and a pressure cap 34 movably connected to the housing 30. The bottom surface of the housing 30 is provided with a through hole 36, and the interior of the housing 30 is provided with a spring 31 and a valve disc 32. One side of the spring 31 abuts against the inner bottom surface of the housing 30, and the other side of the spring 31 causes the valve disc 32 to press against the pressure cap 34. The circumferential surface of the valve disc 32 is also provided with a relief groove 37. The valve disc 32 slides with a guide hole 311 provided in the pressure cap 34 through a guide rod 38, and an exhaust groove 310 is also provided on the inner wall surface of the guide hole 311.

[0028] In summary, under normal conditions, the combined action of the air pressure inside the airbag 5 and the spring 31 reliably ensures that the valve disc 32 adheres to the pressure cap 34, thereby reducing air leakage. When the user feels that the internal pressure of the airbag 5 is too high, they can push the guide rod 38 to separate the valve disc 32 from the pressure cap 34, at which point the airflow inside the airbag 5 can be released. Therefore, this device has the advantage of convenient pressure adjustment; that is, the user can freely adjust the pressure of the airbag 5 to meet their adjustment needs.

[0029] Furthermore, since one side of the pressure cap 34 is threaded to the inner wall of the outer casing 30 through the external thread 313, the connection between the pressure cap 34 and the outer casing 30 is simple and convenient, and the connection is stable and reliable. At the same time, since the external thread 313 is also provided with a stop part 39, and the stop part 39 fits against the valve disc 32, the valve disc 32 can fit against the stop part 39. At the same time, the setting of the stop part 39 can further compress the spring 31, thus further increasing the reaction force of the spring 31 on the valve disc 32, thereby improving the sealing performance between the valve disc 32 and the stop part 39.

[0030] Furthermore, since the inner wall of the outer casing 30 is also provided with a limiting pin 35, and one end of the limiting pin 35 passes through the limiting pin 35 and fits against the valve disc 32, when it is necessary to adjust the air pressure, the pressure cap 34 can be rotated counterclockwise to cause the external threaded part 313 to move outward until the limiting pin 35 inside the valve disc 32 blocks it. As the pressure cap 34 continues to rotate, the valve disc 32 and the blocking part 39 can be separated, and the air source can be released outward through the gap between them. Based on this, the air pressure can be adjusted by rotating the pressure cap 34, thus making the air pressure adjustment simple and convenient. In particular, by controlling the gap between the opposing surfaces of the valve disc 32 and the blocking part 39, the flow rate of the air pressure released outward can also be adjusted as needed.

[0031] In order to improve the sealing between the valve disc 32 and the opposing surfaces of the stop part 39, the stop part 39 is also provided with an annular groove 312, and a sealing ring 33 is also installed in the annular groove 312.

[0032] Furthermore, since the number of limiting pins 35 and the number of clearance grooves 37 are equal, and there are two limiting pins 35 symmetrically arranged on the inner wall surface of the outer casing 30, the two limiting pins 35 can be used to prevent the valve disc 32 from moving outward, thus avoiding the valve disc 32 breaking off the limiting pins 35 during movement due to excessive air pressure inside the airbag 5. Specifically, during installation, the valve disc 32 moves along the clearance groove 37 and the limiting pins 35 until the valve disc 32 completely passes the limiting pins 35. Then, the valve disc 32 is rotated to cause the clearance groove 37 to be misaligned with the limiting pins 35.

[0033] In addition, since the internal air pressure of the airbag 5 can be adjusted by rotating the pressure cap 34, after the valve disc 32 is in contact with the end face of the blocking part 39, the guide rod 38 is completely located inside the guide hole 311, thus reducing the phenomenon of air leakage caused by accidentally touching the guide rod 38.

[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
