Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, and more particularly to a peritoneal drainage tube structure with a function of collecting exudate. Background Art
[0002] With the continuous development of medical technology in recent years, peritoneal catheter drainage has become a common practice in clinical internal medicine. Peritoneal catheter drainage is a surgical procedure that uses a sterilized needle to penetrate the skin and abdominal wall tissue into the abdominal cavity, then place a drainage tube. This method directs accumulated fluids, such as pus, blood, and exudate, out of the peritoneal cavity. Various tests are then performed to identify the cause of the disease. For patients with large amounts of peritoneal effusion, this method can be used to drain the fluid and, if necessary, administer medication for treatment.
[0003] However, the drainage tubes in the prior art are generally positioned between the tube body and the skin incision by gluing. However, since the tube body and the skin incision cannot fit completely, leakage may occur. The exudate may cause discomfort to the patient and may infect the wound. It may also cause the adhesive patch to become damp and fall off, requiring multiple replacements, increasing the workload of the nursing staff and affecting the patient's recovery.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;
[0021] See also Figures 1 to 4 In the utility model, the peritoneal drainage tube structure with the exudate collection function includes an outer drainage tube 1, the bottom end of the outer drainage tube 1 is fixedly connected to an elastic rubber sleeve 2, the bottom end of the elastic rubber sleeve 2 is fixedly connected to a drainage tube head 3, the inside of the drainage tube head 3 is fixedly connected to an inner tube 4, the top end of the inner tube 4 is inserted into the top of the outer drainage tube 1, the top end of the inner tube 4 is fixedly connected to a diversion hose 6, the outer side of the inner tube 4 is threadedly connected to a second adjustment sleeve 8, the bottom of the second adjustment sleeve 8 is rotatably connected to the top of the outer drainage tube 1, the outer side of the outer drainage tube 1 is fixedly connected to an anti-permeation structure 9, and a sterile patch 5 is fixedly connected between the anti-permeation structure 9 and the outer drainage tube 1.
[0022] In the present invention, the drainage outer tube 1 is used as the guide body, and the inner tube 4 is driven to slide downward along the drainage outer tube 1 by rotating the second adjustment sleeve 8, pushing the drainage tube head 3 to move downward, straightening the elastic rubber sleeve 2, and then passing the drainage tube head 3 through the skin incision into the affected area until the elastic rubber sleeve 2 is completely immersed in the skin, and then rotating the second adjustment sleeve 8 to drive the inner tube 4 to rise along the inside of the drainage outer tube 1, which squeezes the elastic rubber sleeve 2 to deform and expand outward to form a ring-shaped limit, and then the external sterile patch 5 is tightly attached to the skin to achieve internal and external clamping of the incision, reduce leakage, and when exudate occurs, it is anti-permeable at this time. The structure 9 absorbs the exudate and guides it outward to the external collection bag connected to the diversion hose 6 to collect the exudate, thereby realizing the advantages of the device having good anti-seepage effect, more stable adhesive fixing effect, and active drainage and collection of exudate, which solves the problem in the prior art that the tube body and the skin incision are generally positioned by adhesive, and since the tube body and the skin incision cannot be completely fitted together, leakage will occur, and the exudate will cause discomfort to the patient and may infect the wound, and will also cause the adhesive patch to become damp and fall off, requiring multiple replacements, increasing the workload of the nursing staff, and also affecting the patient's recovery.
[0023] See also Figure 3 , wherein: the anti-permeability structure 9 includes an elastic adsorption sponge ring 91, a rubber waterproof ring 92 and a guide tube 93. The inner part of the elastic adsorption sponge ring 91 is slidably connected to the outer side of the drainage outer tube 1, the inner part of the rubber waterproof ring 92 is fixedly connected to the outer side of the elastic adsorption sponge ring 91, one end of the guide tube 93 passes through the inner part of the rubber waterproof ring 92 and is connected to the elastic adsorption sponge ring 91, and the other end of the guide tube 93 is plugged into the outer side of the sterile patch 5.
[0024] In the present invention, the elastic adsorption sponge ring 91 is used to actively absorb the exudate, and the rubber waterproof ring 92 fits the skin to form an anti-exudate restriction area around the incision to prevent outflow and infiltration. The elastic adsorption sponge ring 91 absorbs the exudate and discharges the excess exudate through the guide tube 93 to achieve exudate collection.
[0025] See also Figure 1 and Figure 2 , wherein: the outer side of the drainage outer tube 1 is threadedly connected to a first adjustment sleeve 7 , and the bottom of the first adjustment sleeve 7 is in contact with the sterile patch 5 .
[0026] In the present invention, the first adjustment sleeve 7 can be rotated to descend along the drainage outer tube 1 and contact and press against the sterile patch 5 to achieve better positioning and stability of the drainage outer tube 1.
[0027] See also Figure 3 , wherein: the top of the sterile patch 5 is fixedly connected with a hard ring 51 , and the hard ring 51 is concentrically sleeved on the outside of the rubber waterproof ring 92 .
[0028] In the present invention, the hard ring 51 makes the part of the sterile patch 5 around the incision more stable, and provides better support for the first adjustment sleeve 7 .
[0029] See also Figure 3 , wherein: an annular groove 911 is opened at the bottom of the inner side of the elastic adsorption sponge ring 91, and the annular groove 911 surrounds the outer side of the drainage outer tube 1.
[0030] In the present invention, the annular groove 911 prevents the elastic adsorption sponge ring 91 from directly contacting the wound position after adsorbing the exudate, thereby reducing the contact and stay of the exudate with the wound while achieving the drainage of the exudate.
[0031] See also Figure 1 and Figure 2 , wherein: the front view cross section of the drainage tube head 3 is conical.
[0032] In the present invention, the tapered drainage tube head 3 is convenient for puncture and insertion into the patient's abdomen.
