Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a drainage device for ascites exudate from abdominal puncture. Background Art

[0002] After abdominal surgery, a peritoneal drainage tube is usually left in place for drainage, treatment and observation. The leakage around the peritoneal drainage tube is mostly bloody fluid. These acidic and alkaline mucus are irritating to the skin. Long-term immersion can easily cause irritant dermatitis. If the dressing is not changed in time according to the traditional dressing method, the wet dressing will continue to irritate the surrounding skin, causing local skin redness and swelling or even erosion, and increase the chance of wound infection. The soaked dressing often contaminates the patient's clothes and bedding. The unpleasant smell of the drainage fluid affects not only the patient himself, but also the patients in the same ward.

[0003] The utility model patent with patent publication number: CN218305267U discloses a novel anti-leakage ostomy bag, which includes an ostomy tray and a drainage tube. The ostomy tray is trumpet-shaped, and the ostomy tray is connected and fixed to one side of the anti-leakage ostomy bag. The drainage tube is installed in the anti-leakage ostomy bag through the ostomy tray. The drainage tube passes through the anti-leakage ostomy bag and is connected to the drainage bag to be connected.

[0004] In this patent: the drained liquid is led into the drainage bag through the drainage tube, and the leaked liquid enters the stoma bag. The connection method of the drainage tube is to pass through the anti-leakage stoma bag. The sealing conditions of the position where the drainage tube passes through the anti-leakage stoma bag are limited. The liquid in the stoma bag can easily leak from the point where the drainage tube passes. Therefore, a drainage device for ascites exudate from abdominal puncture that is not prone to leakage is proposed. Utility Model Content

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] A drainage device for ascites exudate from abdominal puncture, such as Figure 1-Figure 5As shown, it includes an ostomy bag 1 and a drainage tube 2, the ostomy bag 1 is provided with a base plate 5, the base plate 5 is provided with a protective paper 6, a through hole 4 is formed by penetrating the protective paper 6, the base plate 5 and a part of the ostomy bag 1, the upper part of the ostomy bag 1 is provided with a lead-out port 3, the ostomy bag 1 is provided with a sealing mechanism 7, the sealing mechanism 7 includes a first fixed seat 71 provided on the ostomy bag 1 and a sealing bag 72 provided on the first fixed seat 71, the first fixed seat 71 is located at the lead-out port 3, the ostomy bag 1 is provided with a piston cylinder 74, a compression bag 75 is provided in the piston cylinder 74, the compression bag 75 is connected with the sealing bag 72 through an air pipe 73, the piston cylinder 74 is provided with an extrusion mechanism for extruding the compression bag 75, the drainage tube 2 passes through the through hole 4, the lead-out port 3 and the sealing bag 72 in sequence and is led out.

[0028] When using the drainage device, first, one end of the drainage tube 2 is led out through the through hole 4, the lead outlet 3 and the sealing bag 72 in sequence, and then the operator can insert one end of the drainage tube 2 into the patient's abdominal cavity and connect the other end to the drainage bag. Then the operator cleans and disinfects the skin around the puncture point of the patient. After disinfection, the protective paper 6 can be torn off, and then the through hole 4 is made to correspond to the puncture point. After the through hole 4 and the puncture point are aligned, the adhesive part of the bottom plate 5 is pressed against the skin around the puncture point. The ascites in the patient's abdomen will be drained into the drainage bag through the drainage tube 2, and the ascites leaked at the puncture point will enter the stoma bag 1 and then flow to the bottom of the stoma bag 1. Since the lead outlet 3 is set at the upper part of the stoma bag 1, the leaked ascites flows to the bottom of the stoma bag 1, so the ascites in the stoma bag 1 can be effectively prevented from leaking from the lead outlet 3. Then the operator can operate the squeezing mechanism to squeeze the compression bag 75, and the compressed gas in the compression bag 75 flows to the sealing bag through the trachea 73. When the patient is in an activity, the ascites in the stoma bag 1 does not flow from the bottom to the outlet 3 and causes leakage. When there is no need to drain the ascites from the patient's abdomen, the operator can remove the drainage bag from the drainage tube 2, and then make the stoma bag 1 no longer attached to the patient's skin. After removing the stoma bag 1 from the patient's skin, the operator can take the drainage tube 2 out of the patient's abdomen, and then the operator can operate the squeezing mechanism so that the squeezing mechanism no longer squeezes the compression bag 75, and the compression bag 75 will be reset. When the compression bag 75 is reset, the gas in the sealing bag 72 will re-enter the compression bag 75 through the trachea 73, and the sealing bag 72 will no longer contact with the drainage tube 2. Then the operator can remove the drainage tube 2 from the stoma bag 1, thereby separating the drainage tube 2 from the stoma bag 1, which is convenient for subsequent cleaning.

[0029] In summary, by setting the outlet 3 at the upper part of the ostomy bag 1, the leaked ascites flows to the bottom of the ostomy bag 1, so the ascites in the ostomy bag 1 can be effectively prevented from leaking from the outlet 3. Then, the operator only needs to operate the squeezing mechanism to make the compression bag 75 close to the drainage tube 2 at the outlet 3, thereby achieving the sealing of the outlet 3 by the sealing bag 72, which can further prevent the ascites in the ostomy bag 1 from leaking from the outlet 3, and can also prevent the odor of the ascites in the ostomy bag 1 from flowing out from the outlet 3, thereby achieving a deodorizing effect.

[0030] like Figure 5 As shown, the extrusion mechanism includes a piston rod 76 slidably arranged in the piston cylinder 74 and a bayonet 77 opened on the piston rod 76, a sliding sleeve 78 is arranged on the piston cylinder 74, a clamping rod 79 is arranged on the sliding sleeve 78, a spring 710 is arranged between the clamping rod 79 and the sliding sleeve 78, and the clamping rod 79 cooperates with the bayonet 77.

[0031] When the operator operates the squeezing mechanism, the initial state spring 710 is in a stretched state, and first, the piston rod 76 can be pushed to move in the direction close to the compression bag 75. The movement of the piston rod 76 in the direction of the compression bag 75 will squeeze the compression bag 75. When the bayonet 77 on the piston rod 76 moves to the clamping rod 79, the spring 710 will reset, and the reset of the spring 710 will drive the clamping rod 79 to move downward and enter the bayonet 77. Then the operator can release the piston rod 76. Since the clamping rod 79 is located at the bayonet 77, the piston rod 76 will be fixed. When there is no need to squeeze the compression bag 75, the operator can pull the clamping rod 79 to move upward, the spring 710 is stretched, the clamping rod 79 will no longer be located at the bayonet 77, the piston rod 76 will become movable, and the compression bag 75 will also be reset. The reset of the compression bag 75 will push the piston rod 76 to reset. After the piston rod 76 is reset, the operator can release the clamping rod 79.

[0032] like Figure 6 As shown, a fixing plate 712 is disposed on the piston cylinder 74 , and a first push plate 711 is disposed on the piston rod 76 .

[0033] The operator can place one finger on the fixing plate 712 and another finger on the first push plate 711 , and bring the two fingers together, thereby making it more convenient for the piston rod 76 to squeeze the compression bag 75 .

[0034] like Figure 7As shown, the drainage device also includes a tube placement mechanism 8, which includes a second fixed seat 81 arranged on the ostomy bag 1 and a swing rod rotatably arranged on the second fixed seat 81, a stopper 84 for supporting the swing rod is arranged on the second fixed seat 81, and the swing rod includes a rotating part 82 rotatably arranged on the second fixed seat 81 and a protrusion 83 arranged on the rotating part 82.

[0035] When the patient needs to get out of bed and move around, the operator can rotate the swing rod so that the swing rod contacts the block 84, and then the operator winds the drainage tube 2 around the rotating portion 82 of the swing rod. The protrusion 83 can prevent the drainage tube 2 from slipping out of the rotating portion 82, thereby achieving the effect of conveniently placing the drainage tube 2, making it easier for the patient to move around. When the patient does not need to place the drainage tube 2 on the rotating portion 82, the operator removes the drainage tube 2 from the rotating portion 82, and then rotates the rotating portion 82 toward the direction close to the ostomy bag 1, thereby storing the swing rod and reducing the space occupied by the drainage device.

[0036] like Figure 7 As shown, a slide bar 85 is slidably provided on the second fixing seat 81 , a second push plate 86 is provided on the slide bar 85 , the slide bar 85 is located on the upper part of the stop block 84 and there is a gap between the slide bar 85 and the stop block 84 .

[0037] When the swing rod rotates to contact the block 84, the operator can push the second push plate 86 in the direction close to the swing rod to make the slide bar 85 slide, so that the swing rod is located between the slide bar 85 and the block 84, thereby fixing the swing rod and making the swing rod more stable. When the swing rod needs to be stored, the operator can push the second push plate 86 to move the slide bar 85 in the direction away from the swing rod, and the slide bar 85 will no longer block the swing rod. Then the operator can rotate the swing rod in the direction close to the ostomy bag 1 for storage.

[0038] like Figure 6 As shown, the fixing plate 712 is aligned with the first pushing plate 711 .

[0039] By aligning the fixing plate 712 with the first push plate 711 , the operator can more conveniently apply force to the first push plate 711 to push the piston rod 76 when pushing the piston rod 76 to squeeze the compression bag 75 .
