Description

Anti-seepage device for abdominal drainage tube

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an anti-seepage device for a peritoneal drainage tube.

Background Art

Patients with clinical cirrhosis, chest and abdominal tumors, tuberculosis, etc. are often prone to large amounts of pleural and abdominal effusions. For such patients, in order to further clarify the diagnosis and relieve symptoms, thoracic and abdominal catheter drainage is usually required.

Although the drainage devices widely used in clinical practice are easy to operate, they are prone to fluid leakage at the puncture site for some patients with high chest and abdominal pressure, the elderly, or loose skin at the puncture site. This not only greatly increases the incidence of chest and abdominal infection after puncture, endangering the safety of patients, but also frequent dressing changes increase the workload of clinical medical care. Therefore, we propose an anti-seepage device for abdominal drainage tubes to solve the above problems.

Utility Model Content

The utility model aims to solve the shortcomings of the background technology and proposes an anti-seepage device for abdominal drainage tube.

To achieve the above objectives, the technical solution adopted by the utility model is: an anti-seepage device for an abdominal drainage tube, comprising: a drainage tube, a fixed seat, a movable seat, a first air bag, an inflation port, a silicone pad, an annular port, a second air bag, an inflation cavity, and an inflation tube, wherein a fixed seat is fixedly installed on the outer wall of the drainage tube, a movable seat is movably installed outside the fixed seat, a first air bag is arranged on the inner side of the movable seat, and the middle part of the first air bag surrounds the drainage tube, an inflation port is arranged on the outer wall of the first air bag, a silicone pad is arranged on one side of the first air bag, and the silicone pad is movably installed on the outer wall of the drainage tube, an annular port is arranged on the outer wall of the drainage tube, and a second air bag is fixedly installed inside the annular port, an inflation cavity is arranged on the inner side of the outer wall of the drainage tube, and the inflation cavity penetrates the inside of the second air bag, and an inflation tube is fixedly installed at the tail end of the inflation cavity.

Preferably, the first airbag and the second airbag are arranged in a symmetrical structure.

Preferably, the inner wall of the movable seat and the outer wall of the fixed seat are both provided with matching threads, and the movable seat and the fixed seat are threadedly connected.

Preferably, the diameter of the silica gel pad is larger than the diameter of the second airbag.

Preferably, the height of the second airbag is lower than the height of the annular opening.

Compared with the prior art, the utility model has the following beneficial effects:

(1) When the drainage tube is inserted into the patient's abdominal cavity, it is inflated through the inflation tube, so that the gas flows into the second airbag through the inflation cavity, so that the second airbag slowly opens and fits against the inner wall of the abdominal cavity, thereby sealing the inside of the puncture incision; at the same time, the first airbag can be inflated through the inflation port, so that the first airbag slowly opens and fits against the outer wall of the abdominal cavity, thereby sealing the outside of the puncture incision. The first airbag and the second airbag can simultaneously seal both sides of the puncture incision, thereby preventing the leakage of accumulated fluid.

(2) The movable seat is threadedly connected to the fixed seat so that the movable seat can rotate and move on the outer wall of the fixed seat, and the movable seat can synchronously drive the first airbag to move, so that the distance between the first airbag and the second airbag can be adjusted, and the distance between the first airbag and the second airbag can be adjusted according to the thickness of the patient's abdominal wall, thereby improving practicality and improving the sealing performance of the first airbag and the second airbag on the puncture incision site.

DETAILED DESCRIPTION

The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

As shown in Figures 1-4, an anti-seepage device for an abdominal drainage tube comprises: a drainage tube 11, a fixed seat 2, a movable seat 3, a first air bag 4, an inflation port 5, a silicone pad 6, an annular port 7, a second air bag 8, an inflation cavity 9, and an inflation tube 10. The fixed seat 2 is fixedly installed on the outer wall of the drainage tube 11, and the movable seat 3 is movably installed outside the fixed seat 2. The first air bag 4 is arranged on the inner side of the movable seat 3, and the middle part of the first air bag 4 surrounds the drainage tube 11. The outer wall of the first air bag 4 is provided with an inflation port 5, a silicone pad 6 is arranged on one side of the first air bag 4, and the silicone pad 6 is movably installed on the outer wall of the drainage tube 11, the outer wall of the drainage tube 11 is provided with an annular port 7, and the second air bag 8 is fixedly installed inside the annular port 7, the inner side of the outer wall of the drainage tube 11 is provided with an inflation cavity 9, and the inflation cavity 9 penetrates the inside of the second air bag 8, and the inflation tube 10 is fixedly installed at the tail end of the inflation cavity 9.

In this embodiment, the first airbag 4 and the second airbag 8 are arranged in a symmetrical structure.

During specific use, when the drainage tube is inserted into the patient's abdominal cavity, it is inflated through the inflation tube 10, so that the gas flows into the second airbag 8 through the inflation cavity 9, so that the second airbag 8 slowly opens and fits against the inner wall of the abdominal cavity, thereby sealing the inside of the puncture incision; at the same time, the first airbag 4 can be inflated through the inflation port 5, so that the first airbag 4 slowly opens and fits against the outer wall of the abdominal cavity, thereby sealing the outside of the puncture incision, so that the first airbag 4 and the second airbag 8 can simultaneously seal the inside and outside of the puncture incision, which can prevent the leakage of accumulated fluid.

In this embodiment, the inner wall of the movable seat 3 and the outer wall of the fixed seat 2 are both provided with matching threads, and the movable seat 3 and the fixed seat 2 are threadedly connected.

During specific use, the movable seat 3 is threadedly connected to the fixed seat 2, so that the movable seat 3 can rotate and move on the outer wall of the fixed seat 2, and the movable seat 3 can synchronously drive the first airbag 4 to move, so that the distance between the first airbag 4 and the second airbag 8 can be adjusted, and the distance between the first airbag 4 and the second airbag 8 can be adjusted according to the thickness of the patient's abdominal wall, thereby improving practicality and improving the sealing of the first airbag 4 and the second airbag 8 to the puncture incision site.

In this embodiment, the diameter of the silicone pad 6 is greater than the diameter of the second airbag 8 .

During specific use, the silicone pad 6 can effectively prevent the second airbag 8 from causing pressure injuries to the patient's skin.

In this embodiment, the height of the second airbag 8 is lower than the height of the annular opening 7 .

During specific use, the height of the second airbag 8 is lower than that of the annular opening 7 , so that when the drainage tube 11 is inserted into the abdominal cavity of the patient, the second airbag 8 will not affect the insertion.
