Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a leakage-proof transabdominal drainage device. Background Art

[0002] Drainage tubes are generally used for surgical drainage, that is, pus, blood, and fluids accumulated between human tissues or in the human body cavity are guided to the outside of the body through the drainage tubes to prevent postoperative infection or affect wound healing, and can also be used to treat diseases. Commonly used drainage tubes include: tear duct drainage tubes, chest drainage tubes, abdominal drainage tubes, ordinary drainage tubes, and many other types. Among them, transabdominal drainage tubes are usually used to drain fluids (such as blood, pus or ascites) in the abdominal cavity after abdominal surgery.

[0003] The transabdominal drainage tube is generally inserted into the abdominal cavity through a small incision in the abdomen, and the end is connected to a drainage bag, which can help drain excess fluid, relieve abdominal pressure, prevent infection, and promote wound healing. By searching the prior art, referring to the drainage tube proposed in the publication (announcement) number CN220404603U, it is pointed out that there is a problem of no effective fixator in the prior art. Therefore, the above-mentioned drainage tube is prone to poor stability during actual use, and the drainage port often leaks. The leaked liquid will flow along the body or the drainage tube and cause pollution. In order to address the above problems, a leakage-proof transabdominal drainage device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4 A leakage-proof transabdominal drainage device comprises a drainage tube 1, a protective cover 2 and a fixing frame 3. The drainage tube 1 and the protective cover 2 are sealed and slidably connected. The surface of the protective cover 2 in contact with the body is provided with an annular mounting groove 9. A liquid absorption ring 10 is installed in the mounting groove 9. The liquid absorption ring 10 is made of cotton and inserted therein to absorb leaked liquid and is convenient to replace.

[0021] The drainage tube 1 slides through the protective cover 2, and the protective cover 2 is connected to the fixing frame 3 through a positioning mechanism. The fixing frame 3 is provided with fixing belts 7 through two installation openings 6. The two fixing belts 7 are connected by Velcro. The two fixing belts 7 are wrapped around the body and the ends are connected by Velcro.

[0022] A collecting tube 8 is threadedly installed on the fixing frame 3 through a threaded channel, a liquid leakage port 12 corresponding to the threaded channel is provided on the protective cover 2, a sealing plug 13 is sealingly and slidingly provided in the liquid leakage port 12, the collecting tube 8 is connected to the sealing plug 13 through an upper push mechanism, two vertical rods 15 are fixedly provided on the inner wall of the protective cover 2, and movable plates 14 connected to the sealing plug 13 are slidably sleeved on the two vertical rods 15 through a dragging mechanism, and the sealing plug 13 is connected to the drainage tube 1 through a limiting mechanism.

[0023] The positioning mechanism includes a positioning rod 4 arranged on the outer wall of the protective cover 2, and a positioning hole 5 corresponding to the positioning rod 4 is provided on the fixing frame 3. The positioning rod 4 enters the positioning hole 5 to realize the positioning and fixing installation of the protective cover 2 relative to the fixing frame 3, thereby ensuring the connection stability between the two.

[0024] The lifting mechanism includes a lifting rod 11 arranged in the collecting tube 8, and the lifting rod 11 is used to lift the sealing plug 13. The lifting rod 11 is fixedly connected to the inner wall of the collecting tube 8 through a fixing plate. With the help of the lifting rod 11, the sealing plug 13 can be lifted up, thereby realizing the opening of the leakage port 12.

[0025] The dragging mechanism includes a spring 16 sleeved on the outside of the vertical rod 15, and the two ends of the spring 16 are elastically connected to the outer wall of the movable plate 14 and the inner wall of the protective cover 2 respectively. The elastic potential energy provided by the spring 16 realizes the dragging operation of the sealing plug 13, so that the sealing plug 13 is in the leakage port 12 in the absence of external force, thereby ensuring the sealing of the leakage port 12.

[0026] The limiting mechanism includes a limiting rod 17 arranged on the sealing plug 13, and a limiting groove 18 corresponding to the limiting rod 17 is arranged on the outer wall of the drainage tube 1. After the limiting rod 17 enters the limiting groove 18, the drainage tube 1 is prevented from moving relative to the protective cover 2, thereby playing a limiting role.

[0027] When the utility model is used, the drainage tube 1 enters the patient's body to realize the operation of extracting and collecting the liquid. A collection bag can be set at the end of the drainage tube 1 to collect the above liquid. The protective cover 2 is outside the drainage tube 1 and at the wound to realize the operation of shielding the wound and collecting the liquid exuding from the wound. The protective cover 2 is fixed by the fixing frame 3, and the fixing frame 3 is fixed by two fixing belts 7. The two fixing belts 7 are wrapped around the patient's body to achieve fixation. The liquid collected in the protective cover 2 leaks out through the leakage port 12 and is discharged through the collection tube 8. A collection bag can also be set at the end of the collection tube 8 to collect the above liquid.

[0028] When the above device needs to be disassembled, first rotate the collecting tube 8 to disengage it from the threaded channel. At this time, the upper push rod 11 no longer pushes up the sealing plug 13. Under the action of the spring 16, the dragging operation of the sealing plug 13 is realized, and the sealing plug 13 re-enters the leakage port 12 to realize the sealing operation of the protective cover 2. At the same time, the limiting rod 17 follows the sealing plug 13 to descend and disengage from the limiting groove 18, and then the limitation of the drainage tube 1 relative to the protective cover 2 is released, and the drainage tube 1 can be pulled out relative to the protective cover 2.

[0029] The protective cover 2 and other components can be separated from the patient's body after the two fixing belts 7 are released, and then the protective cover 2 and the fixing frame 3 can be directly separated.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
