TECHNICAL FIELD
[0001] The present application relates to a medical dressing, in particular a leakage-proof medical dressing for a drainage tube. BACKGROUND
[0002] Puncture drainage is a routine operation in clinical practice. For example, abdominal cavity drainage and thoracic cavity drainage are used to reduce the pressure in the patient's body.
[0003] Patients with decompensated cirrhosis have increased ascites due to low albumin levels and other reasons, which leads to excessive intra-abdominal pressure. Clinically, a single-lumen drainage tube is placed in the left or right lower abdomen of the patient after color ultrasound positioning, referred to as an abdominal cavity drainage tube, and the external part is connected to a drainage bag to complete the drainage of ascites to reduce excessive intra-abdominal pressure. The abdominal cavity drainage tube is placed in the abdominal cavity for a certain length according to the doctor's assessment, and the part left outside the body is placed on the patient's abdominal skin through the abdominal cavity puncture port. Sterile gauze is covered on the abdominal cavity drainage tube, and finally sterile dressing is covered on the sterile gauze to form a sterile and airtight environment. The abdominal cavity drainage tube will be left for several days to several weeks, and during the period of indwelling, the puncture port of the abdominal cavity drainage tube on the patient's skin will be stretched to varying degrees due to excessive intra-abdominal pressure, leading to the expansion of the puncture port of the drainage tube and the leakage of ascites from the puncture port. The existing technology generally covers the puncture port with sterile gauze and sterile dressing to achieve the purpose of stopping liquid, but it has no pressure effect on the puncture port and the effect is generally poor. Moreover, after the water absorption capacity of the gauze is saturated, the dry environment in the sterile dressing is destroyed, which increases the humidity between the skin and the sterile dressing, thereby accelerating the speed of the edge of the sterile dressing from rolling to falling off, increasing the probability of accidental slippage of the abdominal cavity drainage tube. Long-term stimulation of body fluids and the pressure of the drainage tube on the puncture port and the surrounding skin will cause the puncture port and the surrounding skin to turn white, leading to pressure injuries and even increasing the risk of infection. At the same time, the ascites can wet the patient's clothes, increasing the patient's discomfort. Clinically, the method of replacing sterile gauze and sterile dressing or increasing abdominal belts is used to treat the problem, which increases the number of times of replacing the dressing by medical staff and the expenditure of medical consumables, and also increases the number of times of exposing the puncture port to the outside air, increasing the risk of infection. The abdominal belt is a wide cloth belt with a certain elasticity and thickness, which is wrapped around the patient's abdomen to pressurize the abdomen and resist excessive intra-abdominal pressure, but due to the different patient compliance and the operation level of medical staff in clinical practice, the effect of the abdominal belt is generally poor. SUMMARY
[0004] The technical problem to be solved by the present application is to provide a leakage-proof dressing for a drainage tube, which can pressurize the puncture port while absorbing leaked liquid, keep the puncture port dry and sterile, reduce the repeated workload of medical staff in clinical practice, and improve the medical compliance of patients.
[0005] To solve the above technical problems, the present application discloses a leakage-proof medical dressing for a drainage tube, which comprises an absorption dressing and a pressurizing dressing,
[0006] The absorbent dressing comprises a lower absorbent layer, a lower tube hole is opened in the center of the lower absorbent layer, and the lower tube hole is connected to a lower separation line opened at the edge of the lower absorbent layer;
[0007] The pressure dressing comprises an upper absorbent layer, a silica gel plug and a waterproof layer which are sequentially attached from bottom to top;
[0008] The cross-sectional shape and size of the lower absorbent layer, the upper absorbent layer and the silica gel plug are the same and smaller than the size of the waterproof layer. The silica gel plug has a certain hardness and can generate a certain pressure on the patient's puncture port.
[0009] Further, the upper and lower sides of the lower absorbent layer, the lower side of the upper absorbent layer and the lower side of the waterproof layer are provided with removable release paper.
[0010] Further, the release paper above the lower absorbent layer is a middle release paper, the shape and size of the middle release paper are consistent with the cross-sectional shape and size of the lower absorbent layer, and a middle tube hole and a middle separation line of the same size are provided at the corresponding positions of the lower tube hole and the lower separation line.
[0011] Further, the release paper below the upper absorbent layer and the release paper below the waterproof layer constitute an upper release paper, the part below the upper absorbent layer is a center part, the size of the center part is consistent with the size of the upper absorbent layer, and the part below the waterproof layer is a frame part, the area of the frame part is the area of the waterproof layer minus the area of the center part.
[0012] Further, the release paper below the lower absorbent layer is a lower release paper, the shape and size of the lower release paper are consistent with the waterproof layer, and four adhesive tapes are pasted on the other side of the lower release paper. By tearing off the adhesive tape and pasting it on the edge of the waterproof layer, the waterproof layer can be fixed on the patient's skin, which can reinforce the waterproof layer and fix the drainage tube to avoid accidental slipping.
[0013] Further, the lower absorbent layer and the upper absorbent layer both use sodium carboxymethyl cellulose, which is a hydrocolloid with strong liquid absorption capacity. The non-gel solid absorbs liquid to form a gel that can keep the wound moist and promote wound healing.
[0014] Further, the waterproof layer uses a polyurethane semi-permeable membrane, which allows only oxygen and water vapor to pass through, and water and various microorganisms cannot pass through, which can prevent microbial invasion.
[0015] Further, the lower absorption layer, the upper absorption layer and the silica gel plug are square with a size of 3cm*3cm, and the waterproof layer is rectangular with a size of 12cm*12cm. The size can ensure absorption of the exudate without affecting the pressure effect of the waterproof layer, and the waterproof area and the adhesive tape can provide stable pressure.
[0016] Further, the diameter of the lower tube hole is the same as the outer tube diameter of the drainage tube, so that the lower tube hole can just accommodate the outer tube of the drainage tube.
[0017] Further, the absorption layer, the silica gel plug and the waterproof layer are integrally formed, and the silica gel plug and the waterproof layer are transparent, so that whether the puncture port is infected and whether the exudate is excessive can be observed, and medical staff can be reminded to replace in time.
[0018] The utility model discloses an absorption dressing which separates the skin and the drainage tube through the absorption layer of the absorption dressing, reduces the pressure injury of the puncture port and the surrounding skin and the stimulation of ascites or thoracic cavity water, and reduces the secondary damage of the leakage of ascites or thoracic cavity water. The drainage tube is fixed between the two absorption layers, the absorption effect of ascites or thoracic cavity water is improved, the humidity in the sterile dressing is reduced, the service life of the sterile dressing is prolonged, the bending of the abdominal drainage tube caused by simple pressure on the puncture port is avoided, and the drainage effect of ascites or thoracic cavity water is affected. The silica gel plug is used for pressing the puncture port, constant pressure is given to the abdominal puncture port for pressing and closing, and the leakage of ascites or thoracic cavity water is reduced. The four adhesive tapes are used for increasing the overall pressure of the sterile dressing, the curling of the waterproof layer is reduced, the fixing of the dressing can be ensured when the patient moves, and the absorption layer is not displaced due to the movement of the patient. The setting of the release paper further ensures the sterile environment of the dressing, the medical staff can conveniently use, and the sterility is further ensured.
[0019] In summary, the utility model discloses the pressure on the puncture port of the drainage tube, closes the puncture port, absorbs ascites or thoracic cavity water possibly leaked to the outside of the puncture port, ensures the dry and sterile environment in the sterile dressing, reduces the frequency of replacing the dressing and the infection rate, and increases the medical compliance of the patient.
