TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to a chest cavity sealing patch. BACKGROUND
[0002] When the chest wall is penetrated, the chest cavity of a normal human is in a negative pressure state, and the lung tissue is full and plump. However, when the pleural cavity is connected with the outside world, air will enter the chest cavity through the wound, destroy the negative pressure environment, and cause the lung tissue to shrink, so that the normal respiratory function cannot be maintained. Patients are prone to asphyxia and shock due to severe hypoxia, which directly endangers life, so open pneumothorax is a very dangerous condition. In an emergency, the rescuer should take the principle of "quick plugging", and use local materials to close the wound as soon as possible, change the open pneumothorax into closed pneumothorax, and then perform pressure dressing, and send the patient to a hospital with conditions as soon as possible for further rescue.
[0003] The conventional first-aid method is to cover the wound with a clean plastic bag or plastic wrap at the end of deep exhalation, and then cover it with gauze, a mask or a small towel, and then wrap it with a triangular bandage folded into a 20cm wide cloth bandage around the chest to completely cover the dressing. However, this method is not stable and is prone to falling off, and the operation process is complex. SUMMARY
[0004] The purpose of the present application is to provide a chest cavity sealing patch which can improve stability, reduce falling off and facilitate convenient operation when used in first aid.
[0005] To achieve the above purpose, the present application provides a chest cavity sealing patch, which comprises a gel layer, the thickness of the gel layer is 3-5mm, the gel layer has adhesion and is air-tight, a hollow area is arranged on the gel layer, a plurality of small holes are arranged in the hollow area, and the soft film outside the small holes is a whole film structure. A protective film is detachably arranged on one side of the gel layer. The soft film is arranged on the side of the gel layer away from the protective film.
[0006] Among them, the number of small holes is four.
[0007] Among them, when the patient inhales, the soft film is adsorbed on the wound due to pressure difference, and at the same time prevents external gas from entering the chest cavity.
[0008] Among them, when the patient exhales, the gas in the chest cavity overflows from the wound, the soft film is lifted up, and the gas is discharged from the plurality of small holes.
[0009] Among them, the gel layer can be a silica gel layer.
[0010] The gel layer can be a water body gel layer or a hydrogel layer.
[0011] The protective film is provided with a tearing part, which can be rectangular or semicircular.
[0012] The surface of the tearing part is provided with an anti-skid layer with a thickness of 0.05 mm.
[0013] The chest cavity sealing patch of the present application is used by first removing the protective film, then bonding the adhesive gel surface of the gel layer to the chest of the patient, at this time, the hollow area on the gel layer is aligned with the wound, and subsequently, the soft film and the plurality of small through holes can cooperate to prevent external gas from entering and the gas in the chest cavity from being discharged outside when the patient inhales and exhales, and when installed on the wound of the patient, only the protective film needs to be removed, then the adhesive gel surface of the gel layer is bonded to the chest of the patient, which is more convenient to operate, can improve stability during first aid use, reduce falling off, and is beneficial to convenient operation.

The foregoing scheme can improve the stability during first aid use, reduce the falling off, and facilitate convenient operation. It can be understood that the foregoing scheme can improve the stability of the sealing patch during first aid, and can realize convenient operation.
[0024] In the present embodiment, the gel layer 101 has a thickness of 3-5mm, has adhesion and is air-tight, the actual setting thickness can be set according to the needs, the gel layer 101 is provided with a hollow area 102, a plurality of fine holes 103 are provided in the hollow area 102, and the soft film 104 outside the fine holes 103 is a whole film structure; the gel layer 101 can facilitate the convenient adhesion and fixation of the sealing patch on the skin of the patient's wound through its own adhesive part, and its adhesive part can be directly protected after installation through the protective film 105, and during subsequent use, the protective film 105 can be directly torn off, the hollow area 102 can be aligned with the wound area of the patient after the sealing patch is installed on the outside of the patient's wound, and a plurality of fine holes 103 are provided in the inner holes of the hollow area 102, and a plurality of fine holes 103 are provided on the soft film 104. The edge of the connection between the gel layer 101 and the soft film 104 is provided with a sealing layer 108, the sealing layer 108 is provided according to the matching edge structure of the gel layer 101 and the soft film 104, for improving the sealing performance of the edges of the gel layer 101 and the soft film 104, thereby avoiding the air passing through the gap between the edges of the gel layer 101 and the soft film 104 when the patient inhales or exhales.
[0025] The protective film 105 is detachably arranged on one side of the gel layer 101; the protective film 105 is used for protecting the adhesive part on the gel layer 101, and when subsequent adhesion is needed, the protective film 105 can be directly torn off.
[0026] The soft film 104 is arranged on the side of the gel layer 101 away from the protective film 105. The soft film 104 is used for air intake and exhaust cooperation when the patient inhales and exhales, and the soft film 104 can be deformed in a corresponding state to cooperate when the patient inhales and exhales.
[0027] Preferably, the number of the fine through holes 103 is four.
[0028] Preferably, when the patient inhales, the soft film 104 is adsorbed on the wound due to the pressure difference, and at the same time, the external gas is prevented from entering the chest cavity. After the sealing patch is fixed on the skin surface outside the patient's wound through the adhesive part on the gel layer 101, when the patient inhales, the soft film 104 can be directly adsorbed on the patient's wound due to the pressure difference, and at the same time, the external gas is prevented from entering the chest cavity.
[0029] Preferably, when the patient exhales, the gas in the chest cavity overflows from the wound, the soft film 104 is lifted up, and the gas is discharged from the plurality of fine through holes 103. When the patient exhales, the gas in the chest cavity overflows from the wound, and the soft film 104 can be lifted up, and at the same time, the gas is discharged from the four fine through holes 103 on the soft film 104, thereby effectively relieving the symptoms of pneumothorax.
[0030] Preferably, the gel layer 101 can adopt a silicone gel layer.
[0031] Preferably, the gel layer 101 can also adopt any one of a water body gel layer or a hydrogel layer. The hydrogel layer has good adhesion and biocompatibility, can ensure that the sealing patch is firmly adhered to the skin, and at the same time, reduces the irritation to the skin. The gel layer 101 of the present application can preferentially select a hydrogel layer.
[0032] Preferably, the protective film 105 is provided with a tearing part 106, and the tearing part 106 can be rectangular or semicircular. The tearing part 106 will facilitate tearing the protective film 105.
[0033] Preferably, the surface of the tearing part 106 is provided with a 0.05mm thick anti-slip layer 107. The anti-slip layer 107 has an interlaced mesh-like protrusion structure, which facilitates the tearing part 106 to be peeled off. At the same time, air columns 109 can also be provided on the surface of the tearing part 106 to assist in tearing and replace the anti-slip layer 107. The air columns 109 are arranged in a split and spaced manner. When arranged in a straight line, they can also form an anti-slip structure that is easy to tear. The thickness of the air columns 109 can be set to various thicknesses according to the actual situation, and its beveled part and arc part are a continuous structure.
[0034] When using this invention to improve stability, reduce detachment, and facilitate convenient operation during emergency use, the first step is to peel the protective film 105 off the gel layer 101 using the tearing part 106. At this point, the adhesive portion of the gel layer 101 is exposed. Aseptic treatment is performed when the protective film 105 is bonded to the adhesive portion of the gel layer 101. After bonding, the inner and outer sides are isolated to ensure a seal with the surface in contact with the human body, guaranteeing sterility. Then, the adhesive gel surface of the gel layer 101 is adhered... When the adhesive tape is applied to the patient's chest, the perforated area 102 on the gel layer 101 is aligned with the wound. After the sealing tape is fixed to the outer surface of the wound skin through the adhesive portion on the gel layer 101, when the patient inhales, due to the pressure difference, the soft membrane 104 can be directly adsorbed onto the patient's wound, simultaneously preventing external gas from entering the chest cavity. When the patient exhales, the gas in the chest cavity overflows from the wound, pushing up the soft membrane 104, and the gas is discharged from the body through the four tiny pores 103 on the soft membrane 104. Figure 4 The arrow in the diagram indicates the direction of gas expulsion, effectively alleviating pneumothorax symptoms. When installing this sealing patch on a patient's wound, simply peel off the protective film 105 and then adhere the adhesive gel surface of the gel layer 101 to the patient's chest. This makes the operation more convenient and allows for rapid installation on the patient's chest cavity surface, saving valuable time for emergency treatment. Finally, the gel layer 101 is preferably a hydrogel layer to ensure good adhesion and biocompatibility, ensuring the sealing patch adheres firmly to the skin while reducing skin irritation. This improves stability during emergency use, reduces detachment, and facilitates convenient operation.
