Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a device for draining peritoneal effusion. Background Art

[0002] The disposable negative pressure abdominal drainage set currently used in clinical practice installs the drainage tube on the stoma bag. Since the drainage tube is fixed by suture, that is, after the drainage tube is securely placed, 1-2 stitches are sutured at the skin outlet of the drainage tube to tighten the skin outlet, and then the suture is used to tie a knot on the drainage tube to fix the drainage tube. The wound and the drainage tube cannot fit completely, or although the drainage tube is almost fitted when it is placed, the drainage tube is repeatedly moved after the patient turns over or in other situations after surgery, resulting in the wound and the drainage tube not fitting completely, causing the peritoneal effusion to leak out easily. In order to leave enough suture space, the inside of the stoma bag extends from the drainage tube to the periphery, and there is a large area that cannot be attached to the skin, which easily causes the effusion to accumulate on the inside of the stoma bag and is difficult to discharge. The stoma bag needs to be opened more frequently to clean the effusion and change the dressing. Otherwise, it will not only make the patient feel uncomfortable, but also easily cause skin and wound ulceration, and the nursing burden is heavy. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a peritoneal effusion drainage device which can prevent the leakage of peritoneal effusion and reduce the nursing burden.

DETAILED DESCRIPTION

[0021] like Figure 1-4As shown, the utility model provides a device for draining peritoneal effusion, comprising: a drainage tube 10, a rubber ring 11 sleeved on the drainage tube 10, a container 12 connected to one end of the drainage tube 10, a catheter 13 connected to the container 12, and a negative pressure balloon 14 connected to one end of the catheter 13; an adhesive layer 111 is provided on one side of the rubber ring 11, and the rubber ring 11 and the drainage tube 10 are clearance-fitted or interference-fitted.

[0022] Compared with the prior art, the ascites drainage device provided by the utility model, after the drainage tube 10 is fixed to the abdominal wound by suturing and fixing, the protective paper of the adhesive layer 111 is first peeled off, the drainage tube 10 is stabilized by one hand, and the rubber ring 11 is moved along the drainage tube 10 and fits to the periphery of the wound with the other hand to form a sealing structure, which prevents ascites from accumulating at the wound, improves the patient's comfort, and avoids causing skin and wound ulceration. In addition, the rubber ring 11 and the drainage tube 10 have the structural characteristics of clearance fit or interference fit, which can effectively prevent ascites from leaking, reduce the number of nursing times, and greatly reduce the nursing burden. In addition, the rubber ring 11 has a certain elastic stiffness and flexibility, which can reduce the movement range of the drainage tube 10 when the patient turns over, so that the drainage tube 10 maintains a high degree of fit with the wound, and further reduces the risk of fluid leakage.

[0023] It should be noted that when the gap between the rubber ring 11 and the drainage tube 10 is matched, the gap between the rubber ring 11 and the drainage tube 10 is infinitely close to zero, and the rubber ring 11 is kept with sufficient freedom of movement. The rubber ring 11 and the drainage tube 10 are interference fit. Since both the rubber ring 11 and the drainage tube 10 have certain compressive elastic deformation characteristics, the rubber ring 11 can be moved along the drainage tube 10 by applying an appropriate external force, and the sealing is stronger.

[0024] In one embodiment, the drainage tube 10 is wrapped with a flexible water-absorbing member 15, and the flexible water-absorbing member 15 is tightly attached to the side of the rubber ring 11 away from the adhesive layer 111. In special cases such as when the patient turns over for a long time and many times, a gap is formed between the rubber ring 11 and the drainage tube 10, and accumulated fluid may leak out. The accumulated fluid can flow along the drainage tube 10 to the flexible water-absorbing member 15 to be absorbed, thereby avoiding soaking of clothing, bed sheets, and quilt covers.

[0025] In a specific embodiment, see Figure 4The flexible absorbent member 15 includes a porous base layer 151, absorbent cotton 152 and an outer protective layer 153 which are arranged in sequence. Both ends of the outer protective layer 153 are fixedly connected to one side of the porous base layer 151 and surround the absorbent cotton 152 in the middle. Both ends of the porous base layer 151 are provided with adhesive strips 154. Specifically, the porous base layer 151 is made of porous textile cloth, the adhesive strip 154 ​​is double-sided adhesive bonded to one side of the porous base layer 151 near both ends, and the outer protective layer 153 is made of PE tape that can stick to the absorbent cotton 152 and be bonded and fixed to the outer side of the porous base layer 151, wherein the adhesive strip 154 ​​at one end of the porous base layer 151 is bonded and fixed to the drainage tube 10, and then the flexible absorbent component 15 is circumferentially arranged along the drainage tube 10 so that the porous base layer 151 fits the drainage tube 10, and finally the adhesive strip 154 ​​at the other end is bonded to the outer protective layer 153, and the leaked accumulated fluid can be absorbed by the absorbent cotton 152 through the porous base layer 151. After the absorbent cotton 152 is full of accumulated fluid, the flexible absorbent component 15 can be replaced by peeling off the adhesive strip 154.

[0026] In one embodiment, the length of the porous base layer 151 is shorter than the length of the outer protective layer 153 , so that the porous base layer 151 and the outer protective layer 153 can be wound on the drainage tube 10 more smoothly.

[0027] In one embodiment, there is an annular space between the adhesive layer 111 and the drainage tube 10, so that the adhesive layer 111 is close to the wound without compressing the suture, thereby reducing the patient's pain.

[0028] In one embodiment, the width of the annular spacer is 2-4 mm, which minimizes the compression of the suture and reduces the amount of fluid accumulation in the annular spacer. Preferably, the width of the annular spacer is 3 mm.

[0029] In one embodiment, the outer diameter of the rubber ring 11 is 3-5 cm and the thickness is 0.5-1.5 cm. Accordingly, the outer diameter of the adhesive layer 111 is the same as the outer diameter of the rubber ring 11, so as to ensure the reliability of the bonding of the rubber ring 11. At the same time, in special cases such as when the patient turns over for a long time and many times, a gap is formed between the rubber ring 11 and the drainage tube 10, and the accumulated fluid may leak out. The rubber ring 11 will not be too thick to avoid the drainage fluid accumulating there and being unable to be discharged. The rubber ring 11 will not be too thin to have a low supporting effect on the drainage tube 10. Preferably, the outer diameter of the rubber ring 11 is 3.5 cm and the thickness is 1 cm.

[0030] In one embodiment, the rubber ring 11 is in the shape of a hollow cylinder or a hollow truncated cone.

[0031] In one embodiment, a water stop clamp 16 is provided on the drainage tube 10 between the rubber ring 11 and the container 12. By installing or removing the water stop clamp 16, whether the drainage tube 10 drains can be controlled, and the flow rate of the drainage tube 10 can be controlled by adjusting the position of the water stop clamp 16; a water stop clamp 2 17 is provided on the catheter 13. When the negative pressure balloon 14 generates a certain negative pressure in the container 12, closing the water stop clamp 2 17 can prevent the accumulated fluid from entering the negative pressure balloon 14 and contaminating it.

[0032] In one embodiment, a one-way valve 141 is connected to the negative pressure balloon 14, the water stop clamp 17 is closed, the negative pressure balloon 14 is squeezed to discharge the gas, and then the water stop clamp 17 is opened to generate sufficient negative pressure in the container 12. A discharge port is provided at the bottom of the container 12, and a valve 18 is installed at the discharge port for discharging the accumulated fluid.

[0033] In this embodiment, the container 12 is a drainage tube and is not easily deformed.

[0034] In another embodiment, see Figure 5 The utility model provides a device for drainage of peritoneal effusion, comprising: a drainage tube 10, a rubber ring 11 sleeved on the drainage tube 10, a container 12 connected to one end of the drainage tube 10, and a negative pressure balloon 14 connected to the drainage tube 10 between the rubber ring 11 and the container 12, a one-way valve 141 connected to the negative pressure balloon 14; an adhesive layer 111 is provided on one side of the rubber ring 11, the rubber ring 11 and the drainage tube 10 are clearance-fitted or interference-fitted, a water stop clip 16 is provided on the drainage tube 10 at the upper and lower ends of the negative pressure balloon 14, respectively, and the rest is the same as the above embodiment. When in use, by installing two water stop clips 16, squeezing the negative pressure balloon 14 to discharge gas, and then removing or opening the two water stop clips 16, the negative pressure balloon 14 is drained by negative pressure, and then the effusion flows into the container 12 under the action of gravity. It should be noted that the container 12 is a drainage tube or a drainage bag.
