Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an abdominal drainage tube which is easy to fix. Background Art

[0002] Puncture and drainage is a common surgical procedure, which generally involves inserting a puncture trocar into a tissue or body cavity to create a channel, and then implanting a drainage tube to drain pus, blood, and fluid.

[0003] Existing drainage tubes use air bags and silicone pads to work together to fix the drainage tubes on the patient's abdomen, allowing medical staff to fix the drainage tubes without suturing, saving time and effort. However, the thickness of the fat layer in the abdomen of different patients varies, resulting in inconsistent tightening of the air bags and silicone pads with fixed spacing for different patients. For patients with thicker fat, excessive tightening may cause discomfort, while for patients with thinner fat, the fixation may easily become loose. Utility Model Content

[0004] The utility model aims to provide an abdominal cavity drainage tube which is easy to fix, so as to solve the above problems existing in the prior art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A peritoneal drainage tube that is easy to fix, comprising a drainage tube body, the end of the drainage tube body is tapered, a drainage interface is fixedly installed on the top of the drainage tube body, a first air bag is fixedly installed on the surface of the drainage tube body, an inflation interface is fixedly installed on the surface of the drainage interface, one end of the inflation interface is fixedly installed with an airflow duct fixedly connected to the inner wall of the drainage tube body, the other end of the airflow duct is connected to the interior of the first air bag, a silicone pad is sleeved on the surface of the drainage tube body and located between the first air bag and the drainage interface, a second air bag is fixedly installed on the inner wall of the silicone pad, the other side of which is in contact with the surface of the drainage tube body, an air injection tube in contact with the interior of the second air bag is fixedly installed on the surface of the silicone pad, and a sealing plug is fixedly installed on the other end of the air injection tube.

[0007] The beneficial effects of the present invention are as follows: when the drainage tube body is inserted into the patient along the pre-incision wound, the medical staff injects fluid into the first airbag through the inflation interface and the airflow duct, causing the first airbag to expand. After the first airbag expands, it can be tightly fitted with the inner side of the abdominal wall, effectively preventing the drainage tube from shifting or falling off. At this time, the staff manually or with the help of auxiliary tools adjusts the position of the silicone pad on the drainage tube body so that it is in close contact with the patient's skin surface. After confirming that the silicone pad is in the correct position, the sealing plug is opened and an appropriate amount of gas (such as air or inert gas) is filled into the second airbag through the air injection tube to expand the second airbag. When the second airbag expands, outward pressure is generated. This pressure acts evenly on the inner wall of the silicone pad, thereby forming a close contact and fixing effect between the silicone pad and the drainage tube body, thereby completing the fixation of the silicone pad. By designing the second airbag, the silicone pad does not need to be fixed on the surface of the drainage tube body, but can be moved on the surface of the drainage tube body, so that the device can be adapted to different patients according to their different body shapes, thereby improving the adaptability of the device.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a pot-shaped squeezing bag connected to the interior of the drainage tube body is fixedly installed at the middle position of the drainage tube body.

[0010] Furthermore, an adhesive is applied to a surface of the silicone pad facing the end of the drainage tube body.

[0011] Furthermore, a tube clamp is fixedly installed on the surface of the drainage tube body and located between the squeezing bag and the drainage interface.

[0012] Furthermore, a surface of the drainage interface on one side away from the inflation interface is connected to an injection interface. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] like Figures 1 to 3 As shown, embodiment 1 of the utility model is a peritoneal drainage tube that is easy to fix, including a drainage tube body 1, the end of the drainage tube body 1 is tapered, the top of the drainage tube body 1 is fixedly installed with a drainage interface 2, the surface of the drainage tube body 1 is fixedly installed with a first air bag 3, the surface of the drainage interface 2 is fixedly installed with an inflation interface 9, one end of the inflation interface 9 is fixedly installed with an air flow duct 10 fixedly connected to the inner wall of the drainage tube body 1, the other end of the air flow duct 10 is connected to the interior of the first air bag 3, a silicone pad 4 is sleeved on the surface of the drainage tube body 1 and located between the first air bag 3 and the drainage interface 2, a second air bag 5 is fixedly installed on the inner wall of the silicone pad 4, the other side of which is in contact with the surface of the drainage tube body 1, an air injection tube 6 in contact with the inside of the second air bag 5 is fixedly installed on the surface of the silicone pad 4, and a sealing plug 7 is fixedly installed on the other end of the air injection tube 6.

[0020] When the drainage tube body 1 is inserted into the patient's body along the pre-opened wound, the medical staff injects fluid into the first airbag 3 through the inflation interface 9 and the airflow duct 10, so that the first airbag 3 expands. After the first airbag 3 expands, it can fit tightly with the inner side of the abdominal wall, effectively preventing the drainage tube from shifting or falling off. At this time, the staff manually or with the help of auxiliary tools adjusts the position of the silicone pad 4 on the drainage tube body 1 so that it is in close contact with the patient's skin surface. After confirming that the position of the silicone pad 4 is correct, the sealing plug 7 is opened and an appropriate amount of fluid is filled into the second airbag 5 through the air injection tube 6. Gas (such as air or inert gas) causes the second airbag 5 to expand. When the second airbag 5 expands, it will generate outward pressure, which will act evenly on the inner wall of the silicone pad 4, thereby forming a close contact and fixing effect between the silicone pad 4 and the drainage tube body 1, thereby completing the fixation of the silicone pad 4; by designing the second airbag 5, the silicone pad 4 does not need to be fixed on the surface of the drainage tube body 1, and can be moved on the surface of the drainage tube body 1, so that the device can adapt to different patients and be adjusted according to the body shape of different patients, thereby improving the adaptability of the device.

[0021] Example 2 of the present invention is an abdominal drainage tube that is easy to fix. On the basis of Example 1, a pot-shaped squeezing bag 8 that is connected to the inside of the drainage tube body 1 is fixedly installed in the middle position of the drainage tube body 1.

[0022] When the drainage tube body 1 is draining the fluid in the abdominal cavity, it may become blocked. At this time, by squeezing the squeezing bag 8, a certain negative pressure is generated in the drainage tube body 1, which increases the drainage suction force, thereby loosening and discharging the blockage, thereby keeping the drainage tube body 1 unobstructed. The operation is simple and avoids the phenomenon of medical staff using excessive force to press the drainage tube body 1, which may cause the tube wall to rupture.

[0023] Example 3 of the present invention is an abdominal drainage tube that is easy to fix. Based on Example 1 or 2, the surface of the silicone pad 4 on one side facing the end of the drainage tube body 1 is coated with adhesive.

[0024] By bonding the silicone pad 4 to the patient's skin surface with an adhesive, the drainage tube body 1 can be fixed without the need for medical staff to fix the drainage tube body 1 with sutures. In a specific implementation, a release paper is provided on the adhesive cover.

[0025] Example 4 of the present invention is an abdominal drainage tube that is easy to fix. On the basis of Example 2, a tube clamp 11 is fixedly installed on the surface of the drainage tube body 1 and located between the squeezing bag 8 and the drainage interface 2.

[0026] By adjusting the tightness of the tube clamp 11 , the speed and amount of drainage can be flexibly controlled to suit the patient's specific condition and treatment needs.

[0027] Example 5 of the present invention is an abdominal drainage tube that is easy to fix. Based on any one of Examples 1 to 4, the surface of the drainage interface 2 on the side away from the inflation interface 9 is connected to the injection interface 12.

[0028] By providing the injection port 12, doctors or nurses can directly inject drugs into the body cavity or lesion site where the drainage tube body 1 is located. This drug administration method can ensure that the drugs act directly on the lesion and improve the treatment effect.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
