Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an abdominal cavity drainage tube device. Background Art
[0002] Tubing care is a common clinical nursing task. Improper tube fixation can lead to unplanned tube dislodgement, posing unexpected risks and the pain of re-catheterization. Currently, all tubes are required to be fixed. After abdominal surgery to clear the abdomen, a peritoneal drainage tube or other tube is placed. This placement takes a long time, and loosening of the abdominal wall sutures can lead to unplanned removal of the drainage tube. If the placement is not timely, complications such as bile fistula, pancreatic fistula, bleeding, and abdominal infection may occur. In severe cases, secondary surgery may be necessary, and the patient may even be life-threatening.
[0003] During peritoneal drainage, body fluids are likely to seep out between the drainage tube and the abdominal wall, causing contamination. Therefore, a drainage tube device is designed to prevent contamination caused by body fluid seepage. Utility Model Content
[0004] The utility model provides an abdominal cavity drainage tube device, which is used to solve the technical problem that body fluid easily seeps out between the drainage tube and the abdominal wall hole wall and causes pollution during abdominal cavity drainage.
[0005] The technical solutions adopted in this utility model are as follows:
[0006] A peritoneal drainage tube device includes a collecting bag, wherein a first through hole and a second through hole are sequentially provided on both sides of the collecting bag, a guide tube is nested in the first through hole, and one end of the guide tube extends to the interior of the collecting bag; a fixed disk connected to the guide tube is provided on the outside of the first through hole, the inner side of the fixed disk is fixed to the surface of the collecting bag, and the outer side of the fixed disk is provided with an adhesive layer; a sealing mechanism is nested in the second through hole.
[0007] Preferably, the guide tube is provided with a guide plate extending outward at one end thereof which is arranged inside the collecting bag.
[0008] Preferably, the fixing plate, the guide tube and the guide plate are integrally formed and connected.
[0009] Preferably, the sealing mechanism includes a mounting plate nested inside the second through hole, an elastic ring is fixedly connected to the inner side of the mounting plate, a third through hole is provided in the middle of the elastic ring, and the aperture of the third through hole is smaller than the outer diameter of the existing drainage tube.
[0010] Preferably, a plurality of extension plates are obliquely arranged on the outer side of the mounting plate, and the extension plates are evenly distributed around the central axis of the third through hole; the outer ends of the extension plates are gathered into a cone shape; the external threads of all the extension plates are connected with a conical knob that cooperates with the end of the extension plate, and a fourth through hole coaxial with the third through hole is provided in the middle of the conical knob, and the aperture of the fourth through hole is larger than the outer diameter of the existing drainage tube.
[0011] Preferably, an anti-sliding block is provided on the inner side of each extension plate.
[0012] Preferably, a guide block is provided below the outer end of each extension plate, and a ball is rollingly connected to the inner side of each guide block, and all the balls are circumscribed on a circle that is less than or equal to the outer diameter of the existing drainage tube.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0015] 1. First, the drainage tube is passed through the sealing mechanism and then out of the guide tube. Then, the drainage tube is pulled to the corresponding position of the human body and the position of the collection bag on the drainage tube is adjusted. Then, the adhesive layer on the outer side of the fixing plate is adhered and fixed to the human skin. When body fluid seeps between the drainage tube and the abdominal wall hole wall, the body fluid enters the collection bag through the guide tube for collection, thereby preventing the body fluid from polluting the environment.
[0016] 2. The drainage tube passes through the third through hole into the collection bag, and the drainage tube squeezes and stretches the third through hole, so that part of the surface of the elastic ring is tightly pressed against the surface of the drainage tube, thereby achieving a good sealing effect.
[0017] 3. When the position of the collecting bag on the drainage tube is adjusted, the medical staff tightens the conical knob so that the outer ends of the four extension plates gather inward, thereby pressing the drainage tube, thereby completing the relative position between the collecting bag and the drainage tube, preventing the collecting bag from sliding on the drainage tube, causing the liquid collected in the collecting bag to escape from the third through hole, destroying the sealing condition of the collecting bag, and causing the liquid to pollute the environment.

[0025] The following combination Figures 1 to 3 The utility model is described in detail.
[0026] A peritoneal drainage tube device, in some embodiments, such as Figures 1 to 3 As shown, it includes a collection bag 1, with a first through hole 2 and a second through hole 3 sequentially passing through both sides of the collection bag 1, and the first through hole 2 and the second through hole 3 are coaxial; a guide tube 4 is fixedly nested in the first through hole 2, and one end of the guide tube 4 extends into the interior of the collection bag 1;
[0027] The inner diameter of the guide tube 4 is larger than the size of the wound where the drainage tube 18 is connected to the human body 17; a fixing plate 5 is fixedly provided on the outside of the first through hole 2, and the fixing plate 5 is provided with a hole and is connected to the guide tube 4, and the inner side of the fixing plate 5 is fixedly connected to the surface of the collecting bag 1, and an adhesive layer 6 is laid on the outside of the fixing plate 5; the adhesive layer 6 avoids the hole, and a sealing mechanism is nested in the second through hole 3.
[0028] During specific use, the drainage tube 18 is first passed through the sealing mechanism and then out of the guide tube 4, and then the drainage tube 18 is pulled to the corresponding position of the human body 17, and the position of the collecting bag 1 on the drainage tube 18 is adjusted; then the adhesive layer 6 on the outside of the fixing plate 5 is adhered and fixed to the skin of the human body 17; when body fluid seeps out between the drainage tube 18 and the wall of the abdominal wall hole, the body fluid enters the collecting bag 1 through the guide tube 4 for collection to prevent the body fluid from polluting the environment; and the collecting bag 1 is sealed by the sealing mechanism to prevent the body fluid collected in the collecting bag 1 from leaking out.
[0029] In some embodiments, as Figures 2 and 3 As shown, the guide tube 4 is provided at one end inside the collecting bag 1 and is provided with a guide plate 7 extending outward.
[0030] During specific use, when the leaked liquid enters the guide tube 4, it will be guided into the collection bag 1 by the guide plate 7 to prevent the liquid from flowing back.
[0031] In some embodiments, as Figures 1 to 3 As shown, the fixing plate 5, the guide tube 4 and the guide plate 7 are integrally formed and connected.
[0032] During specific use, the integrity of the drainage structure of the device is increased, and the diversion effect of leaked liquid is improved.
[0033] In some embodiments, as Figures 1 to 3 As shown, the sealing mechanism includes a mounting plate 8 nested inside the second through hole 3, an elastic ring 9 is fixedly connected to the inner side of the mounting plate 8, a third through hole 10 is provided in the middle of the elastic ring 9, and the aperture of the third through hole 10 is smaller than the outer diameter of the existing drainage tube 18; the elastic ring 9 is made of silicone material.
[0034] When the drainage tube 18 passes through the sealing mechanism, Figure 3 As shown, the drainage tube 18 passes through the third through hole 10 into the collecting bag 1, and the drainage tube 18 squeezes and stretches the third through hole 10, so that part of the surface of the elastic ring 9 is tightly pressed against the surface of the drainage tube 18, thereby achieving a good sealing effect.
[0035] In some embodiments, as Figures 1 to 3As shown, four extension plates 11 are obliquely arranged on the outer side of the mounting plate 8, and the extension plates 11 are evenly distributed around the central axis of the third through hole 10; the outer ends of the extension plates 11 are gathered into a cone shape; the external threads of all the extension plates 11 are connected with a conical knob 12 that cooperates with the end of the extension plate 11, and the middle part of the conical knob 12 is provided with a fourth through hole 13 coaxial with the third through hole 10, and the aperture of the fourth through hole 13 is larger than the outer diameter of the existing drainage tube 18.
[0036] When the drainage tube 18 passes through the sealing mechanism, Figure 3 As shown, the drainage tube 18 first passes through the fourth through hole 13 of the conical knob 12, and then passes through the sealing mechanism into the collecting bag 1. At this time, the drainage tube 18 is sleeved on the inner side of the four extension plates 11; when the position of the collecting bag 1 on the drainage tube 18 is adjusted, the medical staff tightens the conical knob 12, so that the outer ends of the four extension plates 11 gather inward, and then press the drainage tube 18, thereby completing the relative position between the collecting bag 1 and the drainage tube 18, preventing the collecting bag 1 from sliding on the drainage tube 18, causing the liquid collected in the collecting bag 1 to escape from the third through hole 10, destroying the sealing condition of the collecting bag 1, and causing the liquid to pollute the environment.
[0037] In some embodiments, as Figures 1 to 3 As shown, an anti-sliding block 14 is provided on the inner side of each extension plate 11 , and the anti-sliding block 14 is made of rubber.
[0038] During specific use, when medical personnel tighten the conical knob 12 so that the outer ends of the four extension plates 11 gather inward and then compress the drainage tube 18, the anti-sliding block 14 abuts against and tightens the drainage tube 18, thereby improving the fixing effect of the drainage tube 18.
[0039] In some embodiments, as Figures 1 to 3 As shown, a guide block 15 is provided below the outer end of each extension plate 11 , and a ball 16 is rollingly connected to the inner side of each guide block 15 , and all the balls 16 are circumscribed on a circle that is less than or equal to the outer diameter of the existing drainage tube 18 .

In addition, the ball 16 and the elastic ring 9 form two-point support for the drainage tube 18, thereby improving the stability of the drainage tube 18.
[0041] In some other embodiments, different from the above embodiment, the outer side surface of the tapered knob 12 is provided with anti-slip lines.
[0042] During specific use, the friction between the medical staff's fingers and the tapered knob 12 is increased, making it easier for the medical staff to operate.
[0043] In some other embodiments, different from the above embodiment, a release film is provided on the surface of the fixing plate 5 to protect the stickiness of the adhesive layer 6. When using the device, the release film can be torn off.
[0044] In some other embodiments, different from the above-mentioned embodiments, a liquid drain port with a closed plug is provided at the bottom of the collecting bag 1 to facilitate the discharge of the liquid in the collecting bag 1 .
[0045] The operating principle of this device:

Then, the drainage tube 18 is pulled to the corresponding position of the human body 17, and the position of the collecting bag 1 on the drainage tube 18 is adjusted; then the adhesive layer 6 on the outside of the fixing plate 5 is adhered and fixed to the skin of the human body 17; when body fluid seeps out between the drainage tube 18 and the wall of the abdominal wall hole, the body fluid enters the collecting bag 1 through the guide tube 4 for collection to prevent the body fluid from polluting the environment; and the collecting bag 1 is sealed by the sealing mechanism to prevent the body fluid collected in the collecting bag 1 from leaking out.
[0047] When the drainage tube 18 passes through the sealing mechanism, Figure 3 As shown, the drainage tube 18 passes through the third through hole 10 into the collecting bag 1, and the drainage tube 18 squeezes and stretches the third through hole 10, so that part of the surface of the elastic ring 9 is tightly pressed against the surface of the drainage tube 18, thereby achieving a good sealing effect.
[0048] When the drainage tube 18 passes through the sealing mechanism, Figure 3 As shown, the drainage tube 18 first passes through the fourth through hole 13 of the conical knob 12, and then passes through the sealing mechanism into the collecting bag 1. At this time, the drainage tube 18 is sleeved on the inner side of the four extension plates 11; when the position of the collecting bag 1 on the drainage tube 18 is adjusted, the medical staff tightens the conical knob 12, so that the outer ends of the four extension plates 11 gather inward, and then press the drainage tube 18, thereby completing the relative position between the collecting bag 1 and the drainage tube 18, preventing the collecting bag 1 from sliding on the drainage tube 18, causing the liquid collected in the collecting bag 1 to escape from the third through hole 10, destroying the sealing condition of the collecting bag 1, and causing the liquid to pollute the environment.
[0049] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
