Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to a pressure-regulating, leak-proof ascites puncture and drainage device. Background Technology

[0002] Under normal circumstances, the human abdominal cavity contains a small amount of fluid (generally less than 200ml), which lubricates intestinal peristalsis. Pathological conditions can lead to an increase in the amount of fluid in the abdominal cavity. There are many causes of ascites, the most common being cardiovascular disease, liver disease, peritoneal disease, kidney disease, and peritoneal metastasis of malignant tumors. Large amounts of ascites can cause breathing difficulties and abdominal pain. Paracentesis, by inserting a drainage tube through the anterior abdominal wall into the peritoneal cavity, drains the ascites to the outside, relieving breathing difficulties and abdominal pain caused by ascites. However, more ascites drainage is not necessarily better. Excessive drainage can cause a sudden drop in intra-abdominal pressure, leading to hypotension or other complications such as breathing difficulties, rapid heartbeat, dizziness, and nausea; in severe cases, it can even cause shock.

[0003] Leakage is a common problem after paracentesis. The main cause of leakage is poor sealing between the drainage tube and the puncture site, leading to ascites leakage between the puncture site and the catheter. Therefore, this application proposes a pressure-adjustable, leakage-preventing paracentesis drainage device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressure-regulating, leak-proof ascites puncture and drainage device.

[0005] An embodiment of this utility model provides a pressure-regulating, leak-proof ascites puncture and drainage device, comprising:

[0006] Drainage tube;

[0007] Leak-proof assembly; the leak-proof assembly includes a connecting cap that can be placed on the skin, a polyethylene film that can be adhered to the skin fixed on the connecting cap, an installation hole through the connecting cap, a rubber ring installed in the installation hole, a drainage tube passing through the rubber ring, the drainage tube being able to seal against the inner wall of the rubber ring, and a pressure regulating mechanism installed on the connecting cap.

[0008] Furthermore, a connecting ring is fixed to the outside of the connecting cover, and an adhesive ring that is stuck to the skin is fixed to the bottom of the connecting ring.

[0009] Furthermore, the polyethylene film is wrapped around the connecting cap and the connecting ring.

[0010] Furthermore, the rubber ring includes an installation ring and two limiting rings, the limiting rings being fixed at both ends of the installation ring, and the limiting rings abutting against the upper end and bottom of the connecting cover.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a pressure-regulating and leak-proof ascites puncture and drainage device, comprising:

[0022] Drainage tube 2;

[0023] Leak-proof component; The leak-proof component includes a connecting cover 1 that can be placed on the skin. The connecting cover 1 is in the shape of an inverted plate. A connecting ring 4 is fixed to the outside of the connecting cover 1. The connecting ring 4 and the connecting cover 1 are integrally formed and are both made of scrap material, so they have a certain support capacity and are not easily deformed. An adhesive ring 6 that is glued to the skin is fixed to the bottom of the connecting ring 4. The top and bottom surfaces of the adhesive ring 6 are both surfaces. One end is glued to the bottom of the connecting ring 4, and the other end can be glued to the skin, so that the connecting cover 1 can be glued to the skin.

[0024] A polyethylene film 3 that can adhere to the skin is fixed on the connecting cover 1. The polyethylene film 3 wraps around the connecting cover 1 and the connecting ring 4, increasing the contact area between them. This not only increases the stability of the connection but also improves the sealing performance. After the rubber ring 6 is bonded to the skin, it provides the first layer of sealing. Adhering the polyethylene film 3 to the skin increases the pressure between the rubber ring 6 and the skin, thereby further improving the sealing performance between the rubber ring 6 and the skin. At the same time, the bonding of the polyethylene film 3 to the skin also provides a sealing effect, thus ensuring the sealing performance between the connecting cover 1 and the skin and effectively preventing leakage between the skin and the connecting cover 1.

[0025] The connecting cover 1 has a through mounting hole 7, and a rubber ring 5 is installed in the mounting hole 7. The rubber ring 5 includes a mounting ring and two limiting rings. The limiting rings are fixed at both ends of the mounting ring and abut against the upper end and bottom of the connecting cover 1. In this way, the rubber ring 5 can be installed in the mounting hole 7 and is not easy to shake. Rubber rings 5 ​​with different inner diameters can be produced to adapt to different models of drainage tubes 2 to ensure the sealing when they abut against each other.

[0026] After the drainage tube 2 passes through the rubber ring 5, the drainage tube 2 can seal against the inner wall of the rubber ring 5. A pressure regulating mechanism is installed on the connecting cover 1. The pressure regulating mechanism includes a connecting tube 8 installed on the connecting cover 1. A valve 9 is installed on the connecting tube 8. An air bladder can be installed on the connecting tube 8. An air inlet pipe is installed on the air bladder. A one-way valve is installed on the air inlet pipe. The one-way valve only allows air to enter the air bladder through the air inlet pipe. A check valve is installed on the connecting tube 8 to prevent air backflow in the connecting tube 8. This part is existing technology and is similar to the squeeze bulb of a manual blood pressure measuring device.

[0027] A control valve is installed on the connecting tube 8 to control the air discharge; by squeezing the air bladder, air can be squeezed into the connecting cover 1, thereby creating a certain pressure, which controls the pressure between the connecting cover 1 and the inside of the tissue, making them balanced, thus preventing leakage between the drainage tube and the skin tissue. Opening the control valve can release pressure and control the pressure. This setting can regulate the pressure between the connecting cover 1 and the skin tissue to prevent leakage.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
