Description

Technical Field

[0001] The utility model relates to the technical field of abdominal drainage dressings, in particular to a pressurized dressing for an abdominal drainage tube. Background Art

[0002] Ascites is a common complication in patients with decompensated cirrhosis. Once ascites occurs, the 1-year mortality rate is about 20% and the 5-year mortality rate is about 44%. In terms of treatment, some patients have refractory ascites and the application of diuretics is ineffective. The guidelines suggest that abdominal puncture and drainage of ascites is an effective treatment for refractory ascites or recurrent ascites, and it is widely used in hospitalized patients with liver disease. However, due to the high intra-abdominal pressure caused by a large amount of ascites, and the fact that patients with cirrhosis often have malnutrition and a thin wall fat layer, ascites leakage after the indwelling of the abdominal drainage tube is relatively common. The impact of ascites leakage is mainly: ① Ascites exudate has an irritating effect on the local skin and increases the risk of local infection. If the leakage is obvious, it may affect blood pressure, further aggravate the progression of liver disease, and affect the prognosis of patients with cirrhosis. ② Ascites leakage can seriously affect the quality of life of patients. Patients need to frequently change clothes or bed sheets, bedding, etc., which is especially difficult for patients with limited mobility, affecting the comfort of patients. For some patients, leakage is more obvious when they turn over or stand up, which limits their activities. ③ It seriously increases clinical workload and medical expenses.

[0003] Therefore, in summary, ascites leakage is a common and difficult problem for clinical physicians. In clinical practice, we try to add a rubber cap to the medicine bottle in addition to the conventional dressing, which helps to reduce leakage to a certain extent, but the pressure cannot be controlled and the operation lacks certain standards. Utility Model Content

[0004] The utility model aims to provide a pressurized dressing for an abdominal drainage tube, which enables the dressing to control pressure at a wound.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressurized dressing for an abdominal drainage tube, comprising an inner patch and an outer cover arranged thereon, wherein the outer cover is threadedly connected with a screw, one end of the screw is rotatably arranged on the inner patch, and a soft pad is arranged at the bottom of the inner patch.

[0006] Preferably, a communication port is provided on the outer cover, a screw sleeve is provided in the communication port, a scale line is provided on the screw sleeve (13), and the screw thread is provided in the screw sleeve.

[0007] Preferably, a rotation groove is provided on the inner sticker, and one end of the screw is arranged in the rotation groove.

[0008] Preferably, a rotating handle is provided on the screw rod.

[0009] In the above technical scheme, the utility model provides a pressurized dressing for an abdominal drainage tube, which has the following beneficial effects: by changing the dressing into two layers, the inner patch is used to contact the skin and fix it, and the pressure can be controlled by the cooperation of the outer cover and the screw. At the same time, the soft cushion ensures that when the pressure is controlled, the skin in contact will not feel pain, and the pressure is controlled by raising and lowering the screw. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1-2 As shown, a pressurized dressing for an abdominal drainage tube includes an inner patch 1 and an outer cover 11 arranged thereon, a screw 16 is threadedly connected to the outer cover 11, one end of the screw 16 is rotatably arranged on the inner patch 1, and a soft pad 15 is arranged at the bottom of the inner patch 1.

[0017] Specifically, when in use, the inner patch 1 is attached to the patient's skin, and then the screw 16 is turned to pressurize the local catheter placement. If ascites needs to be drained, the screw 16 is turned in the opposite direction to make the local pressurization ineffective and perform ascites drainage.

[0018] In the above scheme, the dressing is changed into two layers, the inner patch 1 is used to contact the skin and fix it, and the pressure can be controlled by the cooperation of the outer cover 11 and the screw 16. At the same time, the soft cushion 15 ensures that the skin in contact will not feel pain when the pressure is controlled, and the pressure is controlled by raising and lowering the screw 16.

[0019] As an embodiment further provided by the present invention, according to Figure 1and Figure 2 As shown, a communication port 12 is provided on the outer cover 11 , a screw sleeve 13 is provided in the communication port 12 , numbers are provided on the screw sleeve 13 to indicate the pressure size, and a screw rod 16 is threadedly disposed in the screw sleeve 13 .

[0020] Specifically, the screw 16 is turned, and the screw 16 rotates in the communication port 12 on the outer cover 11 , and the pressure is controlled according to the numbers on the screw sleeve 13 , that is, the screw sleeve 13 is provided with scale lines.

[0021] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, a rotation groove 14 is provided on the inner sticker 1 , and one end of a screw rod 16 is arranged in the rotation groove 14 .

[0022] Specifically, one end of the screw 16 rotates in the rotating groove 14 and squeezes the inner sticker 1 toward the local tube placement.

[0023] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, a rotating handle 17 is provided on the screw rod 16 .

[0024] Specifically, the screw rod 16 is controlled by rotating the rotating handle 17 .

[0025] Working principle: When in use, stick the inner patch 1 on the patient's skin, then turn the handle 17 to drive the screw 16, one end of the screw 16 rotates in the rotating groove 14, and squeezes the inner patch 1 toward the local catheter placement to pressurize the local catheter placement. If ascites needs to be drained, then turn the screw 16 in the opposite direction to make the local pressurization invalid and drain the ascites.

[0026] It should be noted that the inner sticker 1 and the outer cover 11 are bonded together at their edges.

[0027] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
