Description

A gas pressure device for popliteal cysts Technical Field

[0001] This invention relates to the field of popliteal cyst treatment technology, and in particular to a gas pressure device for popliteal cysts. Background Technology

[0002] Popliteal cysts refer to the general term for enlarged deep bursae in the popliteal fossa or posterior bulging of the synovial bursa of the knee joint, causing pain and swelling in the back of the knee, and a palpable elastic soft tissue mass. Currently, the primary treatment for popliteal cysts is surgical excision. The principle of non-surgical treatment is to destroy the cyst wall, squeeze out the cyst fluid, and apply pressure bandage. Non-surgical treatments include manual therapy, acupuncture, and nerve block therapy. After the cyst wall is ruptured using any of these methods, appropriate pressure must be maintained on the affected area for about 4 weeks to ensure close contact and adhesion between the cyst walls, preventing recurrence. Therefore, there is an urgent need for a pneumatic pressure device for popliteal cysts to apply continuous and sufficient pressure to the cyst surface, allowing the cyst walls to fuse together stably and achieve a cure.

[0003] Summary of the Invention

[0004] The purpose of this invention is to provide a gas pressure device for popliteal cysts to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following solution: a gas pressure device for popliteal cysts, comprising an elastic band, the two ends of which are detachably connected to the two ends of a fixing strap via Velcro, a plurality of airbags being installed inside the fixing strap, a magnetic sheet being installed on the side of the fixing strap facing the elastic band, a second connecting tube being fixedly connected to the end of the fixing strap away from the magnetic sheet, one end of the second connecting tube extending into the fixing strap communicating with the airbags, and a control component being detachably connected to the end of the second connecting tube away from the airbags.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Referring to Figures 1-8, the present invention provides a gas pressure device for popliteal cysts, including an elastic band 3. The two ends of the elastic band 3 are detachably connected to the two ends of a fixing band 1 via Velcro. The fixing band 1 has a receiving cavity, and an airbag 17 is disposed in the receiving cavity. A magnetic sheet 4 is installed on the side of the fixing band 1 facing the elastic band 3. The magnetic sheet 4 is detachably connected to the airbag 17. A second connecting tube 11 is fixedly connected to the end of the fixing band 1 away from the magnetic sheet 4. One end of the second connecting tube 11 extends into the receiving cavity and communicates with the airbag 17. A control component is detachably connected to the end of the second connecting tube 11 away from the airbag 17.

[0030] This invention uses an elastic band 3 to attach the fixing band 1 to the patient's affected area. Simultaneously, a control component can control the size of the airbag 17 corresponding to the affected area, allowing the airbag 17 to push the magnetic plate 4 into close contact with the affected area. This allows the magnetic plate 4 to apply appropriate and continuous pressure to the cyst, causing the cyst wall of the ruptured cyst to fuse together, preventing further leakage. Furthermore, the airbag 17 pushes the magnetic plate 4, ensuring it applies continuous and sufficient pressure to the cyst surface, promoting cyst wall fusion and achieving a healing effect. The magnetic plate 4, closely adhering to the skin, also provides continuous physical therapy to the popliteal cyst, achieving a healing effect and effectively improving the cure rate.

[0031] The fixation strap 1 is an elastic bandage that can provide fixation, effectively securing the magnetic plate 4 to the affected area and protecting soft tissues such as blood vessels, nerves, muscles, and skin. The tightness can be adjusted using Velcro, allowing for adjustments based on the limb size of different patients. The fixation strap 1 and the elastic band 3 are installed and removed using Velcro, enabling them to adapt to knee joints of different circumferences and provide effective fixation.

[0032] Airbag 17 is made of rubber, which effectively avoids skin pressure injury and allergies. Airbag 17 is oval and flat.

[0033] The design is further optimized by creating a limiting hole 2 at the position of the elastic band 3 facing the magnetic plate 4. The limiting hole 2 is adapted to fit the knee. When the patient's knee is within the limiting hole 2, the limiting hole 2 ensures that the patient's knee is within the limiting hole 2, allowing the fixation band 1 to be stably positioned at the patient's affected area and preventing the fixation band 1 from detaching from the affected area.

[0034] The design was further optimized by reserving several cavities within the fixing belt 1, with each cavity corresponding to an airbag 17.

[0035] The design was further optimized by evenly distributing several accommodating cavities within the fixing band 1. Due to the varying locations of the affected areas, these accommodating cavities ensure that the magnetic sheet 4 can effectively and closely adhere to the affected area.

[0036] The design was further optimized so that the side of the magnetic sheet 4 away from the fixing band 1 is detachably connected to the popliteal fossa.

[0037] By inflating the airbag 17 corresponding to the affected area, the inflated airbag 17 compresses the magnetic sheet 4, allowing the magnetic sheet 4 to fit tightly against the patient's affected area.

[0038] The magnetic sheet 4 is made of a cloth with magnetic powder, and its size can be adjusted according to the affected area; so that the magnetic sheet 4 can cover the affected area and has a therapeutic effect on local popliteal cysts.

[0039] By using the airbag 17 to push the magnetic plate 4, an appropriate pressure can be applied to the cyst, causing the ruptured cyst wall to fully adhere and prevent further leakage of cyst fluid, thus achieving a cure.

[0040] The scheme is further optimized. The control component includes a first connecting pipe 6, which is threadedly connected to a second connecting pipe 11. The end of the first connecting pipe 6 away from the second connecting pipe 11 is fixedly connected to and connected to a hand-held inflatable ball 5. The end of the first connecting pipe 6 near the hand-held inflatable ball 5 is fixedly connected to and connected to a pressure gauge 9.

[0041] The first connecting tube 6 is threadedly connected to the second connecting tube 11. After the airbag 17 is inflated by holding the inflatable ball 5, the first connecting tube 6 is unscrewed to avoid the inflatable ball 5 from hindering the patient's movement, so that the first connecting tube 6 and the inflatable ball 5 will not hinder the patient's movement.

[0042] The inflation pressure of the airbag 17 can be controlled by the pressure gauge 9.

[0043] In a further optimized design, a limiting groove 12 is formed on the inner wall of the second connecting pipe 11. A movable disc 14 is slidably connected to the limiting groove 12. A spring 13 is fixedly connected to the end of the movable disc 14 facing the airbag 17. The end of the spring 13 away from the movable disc 14 is fixedly connected to the limiting groove 12. A sealing plug 16 is fixedly connected to the end of the movable disc 14 away from the spring 13. The sealing plug 16 is slidably connected to the inner wall of the second connecting pipe 11. The outer diameter of the sealing plug 16 is adapted to the inner diameter of the second connecting pipe 11.

[0044] In a further optimized design, several venting grooves 15 are provided around the sealing plug 16, and these venting grooves 15 are located on the movable plate 14. The venting grooves 15 allow gas from the first connecting pipe 6 to enter the second connecting pipe 11, or vice versa.

[0045] The design was further optimized by creating several ventilation slots at equal intervals of 15.

[0046] In a further optimized design, a fixing post 7 is provided inside the end of the first connecting pipe 6 facing the second connecting pipe 11. The fixing post 7 is fixedly connected to the inner wall of the first connecting pipe 6 through several connecting rods 8. The end of the fixing post 7 extending out of the first connecting pipe 6 is detachably connected to the sealing plug 16.

[0047] The length of the fixing post 7 extending out of the first connecting pipe 6 is greater than the length of the sealing plug 16, so that the fixing post 7 can push the sealing plug 16 into the limiting groove 12.

[0048] To prevent the gas inside the airbag 17 from escaping through the second connecting tube 11 after the first connecting tube 6 is removed, the movable plate 14 is moved by the elasticity of the spring 13, so that the movable plate 14 can insert the sealing plug 16 into the inner wall of the second connecting tube 11, effectively preventing the gas inside the airbag 17 from escaping through the second connecting tube 11.

[0049] When inflation is required, tighten the first connecting tube 6 onto the second connecting tube 11. At this time, the fixing post 7 can push the sealing plug 16 so that the sealing plug 16 does not block the inner wall of the second connecting tube 11, allowing the gas to enter the airbag 17 through the ventilation groove 15 and the second connecting tube 11 in sequence.

[0050] When it is necessary to deflate the airbag 17, tighten the first connecting tube 6 onto the second connecting tube 11. At this time, the fixing post 7 can push the sealing plug 16 so that the sealing plug 16 does not block the inner wall of the second connecting tube 11. Then open the deflation valve of the hand-held inflatable ball 5. The gas in the airbag 17 passes through the second connecting tube 11, the ventilation groove 15, and the first connecting tube 6 in sequence and is discharged from the deflation valve of the hand-held inflatable ball 5.

[0051] Working process: First, place the fixation strap 1 in the popliteal fossa and make the magnetic piece 4 abut against the popliteal fossa. At the same time, make the knee position within the limiting hole 2. Adjust the tightness by attaching the two ends of the elastic band 3 to the fixation strap 1. Then, locate the airbag 17 corresponding to the affected area. Tighten the first connecting tube 6 to the second connecting tube 11 on the airbag 17. Squeeze the hand-held inflatable ball 5 to inflate the airbag 17. The pressure of the airbag 17 can be checked through the pressure gauge 9. After the airbag 17 tightly abuts the magnetic piece 4 against the popliteal fossa, unscrew the first connecting tube 6. The patient can then start exercising. At the same time, due to the compression of the airbag 17, the magnetic piece 4 can abut against the affected area, allowing the magnetic piece 4 to continuously treat the affected area. Through the action of the limiting hole 2 and the airbag 17, the fixation strap 1 can be effectively positioned in the popliteal fossa when the patient exercises, and the magnetic piece 4 can be effectively and tightly fitted to the affected area, improving the treatment effect.

[0052] When it is necessary to remove the fixing strap 1, tighten the first connecting tube 6 onto the second connecting tube 11, and open the deflation valve of the hand-held inflatable ball 5. The gas in the airbag 17 will pass through the second connecting tube 11, the vent 15, and the first connecting tube 6 in sequence, and then be discharged from the deflation valve of the hand-held inflatable ball 5. Then, the elastic band 3 can be removed from the fixing strap 1.
