[0028] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0029] The utility model provides Figures 1 to 3 As shown in , a local pressure device after body surface cyst resection is intended to solve the disadvantage that existing pressure bandaging solutions cannot be used continuously after body surface cyst resection in different recovery stages.
[0030] The local pressurization device after the removal of the surface cyst of the body mainly includes: an inner layer 100, a surface layer 200 and an elastic inner layer. The inner layer 100 is used to fit the patient's skin. The inner layer 100 can be made of skin-friendly materials, and the surface layer 200 can be made of waterproof and tough materials. The two ends of the surface layer 200 in the length direction are fixedly connected to the inner layer 100. The inner layer is arranged between the inner layer 100 and the surface layer 200. An air cavity 311 is formed inside the inner layer. The cross-sectional area of the air cavity 311 gradually decreases at both ends in the length direction. An airbag part 310 is formed in the middle of the inner layer, and elastic parts 320 are formed at both ends of the inner layer. The two ends of the inner layer in the length direction are fixedly connected to the surface layer 200.
[0031] First, traditional pressure bandaging technology is difficult to provide local pressure effects. Since the bandaging methods of gauze blocks and elastic bandages are relatively rough, the pressure distribution will be uneven, and it will not be able to provide appropriate pressure effects for specific areas. It is also difficult to use continuously after the removal of surface cysts of different sizes and different recovery stages. Repeated removal and bandaging are required, which affects the recovery of the wound. Secondly, for wounds in the joint area, traditional pressure bandaging methods may limit the normal movement of the joints. The flexibility and range of motion of the joints are crucial to the patient's recovery, and traditional bandaging methods may affect the patient's daily life and rehabilitation training due to their restrictiveness.
[0032] The utility model arranges an embedded layer, fixes the inner layer 100 on the patient's skin, and then inflates the airbag part 310, so that the airbag part 310 can expand and pressurize a specific part of the patient. By adjusting the air pressure of the airbag part 310, it can adapt to the patient's continuous use in different recovery stages after surface cyst resection. At the same time, because the airbag part 310 enhances the effect of local pressurization, it can reduce the pressure on other parts, reduce the restriction on joint movement, and is beneficial to the patient's recovery.
[0033] In some embodiments, Figure 1 , Figure 3 As shown in FIG, the inner layer 100, the surface layer 200 and the embedded layer are flush at both ends in the length direction, which can enhance the overall strength.
[0034] In some embodiments, the height of the inner layer protruding toward the surface layer 200 is greater than the height of the air cavity 311 protruding toward the inner layer 100. By reducing the height of the protrusion of the surface layer 200, the foreign body sensation can be reduced during actual use, reducing the impact on daily life.
[0035] In some embodiments, Figure 1 As shown in , a gas nozzle 312 is provided at one end of the surface layer 200 in the length direction, and the gas nozzle 312 is connected to the gas cavity 311. The gas cavity 311 can be inflated through the gas nozzle 312, thereby changing the size of the gas bag part 310 to change the pressure of the gas bag part 310 on the patient.
[0036] In some embodiments, Figure 1 , Figure 3As shown in , the local pressure device after the removal of the surface cyst also includes: two fixing belts 400, the two fixing belts 400 are respectively fixedly arranged at the two ends of the inner layer in the length direction, the two fixing belts 400 are respectively provided with adhesive layers on the surface facing the patient's skin, and the two fixing belts 400 are respectively penetrated with through holes 410. Many surface cysts in common joints are popliteal fossa and cubital fossa. By respectively penetrating through holes 410 on the two fixing belts 400, when they are fixed in the popliteal fossa and cubital fossa, the joint surface can be exposed through the through holes 410, which is beneficial to the flexion and extension of the joint. If it is not used in the joint part, it is also beneficial to ventilation.
[0037] In some embodiments, Figures 1 to 3 As shown in , the local pressurization device after body surface cyst resection also includes: an adjusting bolt 500, the adjusting bolt 500 penetrates the inner layer in the thickness direction, the bolt head of the adjusting bolt 500 is located between the inner layer and the inner layer 100, the nut of the adjusting bolt 500 is located on the surface of the surface layer 200 away from the inner layer 100, and the adjusting bolt 500 is used to adjust the length of the inner layer in the thickness direction. When the patient continues to use the local pressurization device after body surface cyst resection at different recovery stages after body surface cyst resection, if it is inconvenient to adjust the pressure of the airbag part 310 by frequently inflating and deflating air, the local pressure can be conveniently adjusted by rotating the adjusting bolt 500.
[0038] In some embodiments, Figures 1 to 3 As shown in , the bolt head of the adjusting bolt 500 includes: an extension portion 510, and the bolt head of the adjusting bolt 500 is extended toward the width direction to form the extension portion 510;
[0039] The protrusion 520, the bolt head of the adjusting bolt 500 and the extension 510 are respectively protruded toward the inner embedded layer to form the protrusion 520. The friction between the adjusting bolt 500 and the airbag part 310 can be enhanced, the probability of relative sliding between the adjusting bolt 500 and the airbag part 310 can be reduced, and the shift of the pressurized part can be prevented.
[0040] In some embodiments, Figures 1 to 3 As shown in FIG. 1 , a pressure sensor is provided on the surface of the bolt head of the adjusting bolt 500 facing the inner layer 100. The pressure sensor can be used to monitor the pressure of the local pressurization to avoid excessive pressure causing local tissue necrosis.
[0041] In some embodiments, Figure 1 , Figure 2As shown in , the local pressure device after the removal of the body surface cyst also includes: a heat shrink layer 600, which is arranged on the surface of the surface layer 200 away from the inner layer 100, and the heat shrink layer 600 is fixedly connected to the surface layer 200 at both ends in the length direction. The heat shrink layer 600 is made of a heat shrink material, and the heat shrink layer 600 can be shrunk by heating. In actual use, by heating the heat shrink layer 600, the length of the heat shrink layer 600 in the length direction can be reduced, so that the surface layer 200 is pulled so that the length of the surface layer 200 in the length direction is also reduced, so that the protrusion height of the embedded layer toward the surface layer 200 is reduced, and the protrusion height of the embedded layer toward the inner layer 100 is increased, so as to adapt to the use of more parts.
[0042] In some embodiments, Figures 1 to 3 As shown in the figure, the inner layer 100 is a hydrocolloid dressing layer, and the surface layer 200 is a nylon textile layer. It can improve the use experience.
[0043] In summary, a local pressurization device after the resection of a body surface cyst is provided, comprising an inner layer, a surface layer and an elastic inner layer, wherein the inner layer is used to fit with the patient's skin, the two ends of the surface layer in the length direction are fixedly connected to the inner layer, the inner layer is arranged between the inner layer and the surface layer, an air cavity is formed inside the inner layer, the cross-sectional area of the air cavity gradually decreases at both ends in the length direction, an airbag portion is formed in the middle of the inner layer, and elastic portions are formed at both ends of the inner layer. The utility model provides an inner layer, fixes the inner layer on the patient's skin, and then inflates the airbag portion, so that the airbag portion can expand and pressurize a specific part of the patient. By adjusting the air pressure of the airbag portion, the utility model can adapt to the patient's continuous use in different recovery stages after the resection of a body surface cyst. At the same time, because the airbag portion enhances the effect of local pressurization, the pressure on other parts can be reduced, the restriction on joint movement can be reduced, and the patient's recovery is beneficial.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
