Description

Technical Field

[0001] This utility model relates to the field of intestinal drainage technology, specifically to an intestinal decompression drainage tube. Background Technology

[0002] Preoperative bowel preparation is essential for common intestinal surgeries such as those for intestinal obstruction, intestinal necrosis, and intestinal tumors. This reduces the risk of postoperative wound and abdominal infection. Intestinal obstruction surgeries, in particular, are often emergency procedures requiring rapid clearance of the proximal obstructed bowel. Currently, the intestinal decompression and drainage tubes used for preoperative preparation are typically ordinary medical soft tubes with a diameter similar to the purse-string suture site, prepared by the surgeon after assessment. There are no dedicated intestinal decompression and drainage tubes. However, due to intestinal edema and other factors, these ordinary medical soft tubes are prone to slippage, leading to leakage of intestinal contents and secondary contamination. Furthermore, when intestinal contents obstruct the bowel, the drainage tube needs to be replaced to continue drainage. However, the process of replacing the obstructing tube with a new one can easily contaminate the incision site with intestinal contents. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide an intestinal decompression drainage tube that can prevent the tube from dislodging during intestinal decompression drainage. Furthermore, by designing the decompression drainage tube in two separate parts, it eliminates the need to perform any actions at the interface between the decompression drainage tube and the intestinal lumen when the tube becomes blocked, thus avoiding contamination of the incision by contents due to actions at the interface.

[0004] To solve the above-mentioned technical problems, this utility model provides an intestinal decompression drainage tube, including a first decompression drainage branch tube and a second decompression drainage branch tube, wherein the first decompression drainage branch tube and the second decompression drainage branch tube are detachably connected.

[0005] The first pressure-reducing drainage branch includes a first branch body. A pressure-reducing drainage head is provided at one end of the first branch body away from the second pressure-reducing drainage branch. A drainage hole matching the first branch body is opened through the pressure-reducing drainage head. The outer diameter of the pressure-reducing drainage head is larger than the outer diameter of the first branch body.

[0006] Furthermore, the first pressure-reducing drainage branch pipe is threaded or plugged into connection with the second pressure-reducing drainage branch pipe.

[0007] Furthermore, the first branch tube body is provided with a first connecting part at one end near the second pressure-reducing drainage branch tube, and a connector is provided on the outside of the first connecting part. The second pressure-reducing drainage branch tube includes a second branch tube body, and a second connecting part matching the connector is provided at one end of the second branch tube body near the first branch tube body. The second connecting part has a U-shaped structure.

[0008] Furthermore, an operating part is symmetrically provided on the outer side of the first connecting part to facilitate the connection and separation of the first pressure-reducing drainage branch tube and the second pressure-reducing drainage branch tube.

[0009] Furthermore, when the first pressure-reducing drainage branch pipe and the second pressure-reducing drainage branch pipe are threadedly connected, the outer wall of the connector is provided with a first thread, and the inner wall of the second connecting part is provided with a second thread that matches the first thread.

[0010] Furthermore, the outer wall of the first branch pipe body is in contact with the inner wall of the second branch pipe body, or the first branch pipe body and the second branch pipe body are connected and their inner and outer diameters are equal, or the inner wall of the first branch pipe body is in contact with the outer wall of the second branch pipe body.

[0011] Furthermore, when the first pressure-reducing drainage branch tube and the second pressure-reducing drainage branch tube are connected by a plug-in connection, the connector is made of a soft material, and the outer diameter of the connector is larger than the inner diameter of the second connecting part.

[0012] Furthermore, the outer wall of the first branch pipe body is in contact with the inner wall of the second branch pipe body, or the inner wall of the first branch pipe body is in contact with the outer wall of the second branch pipe body.

[0013] Furthermore, a fixing part is provided at the junction of the pressure-reducing drainage head and the first branch tube body, and the fixing part is used to fix the purse-string suture.

[0014] Furthermore, the drainage hole has a diameter-reducing hole structure along the drainage direction.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The intestinal decompression drainage tube provided by this utility model, by setting a decompression drainage head, can prevent the main body of the first branch tube from dislodging during intestinal decompression drainage, that is, prevent the decompression drainage tube from dislodging, thereby effectively avoiding secondary pollution caused by leakage of intestinal contents; and by designing the decompression drainage tube into two parts, namely a first decompression drainage branch tube and a second decompression drainage branch tube, the lengths of the first decompression drainage branch tube and the second decompression drainage branch tube can be designed according to needs. To reduce the probability of blockage of the first decompression drainage branch tube, the lengths of the first decompression drainage branch tube and the second decompression drainage branch tube can be shortened. The length ratio of the drainage tubes is optimized by shortening the length of the first decompression drainage tube and increasing the length of the second decompression drainage tube within a reasonable range. This ensures that if the decompression drainage tube becomes blocked, it is more likely that the second decompression drainage tube will be blocked, thus eliminating the need to manipulate the first decompression drainage tube or the interface between the decompression drainage tube and the intestinal lumen. This effectively avoids contamination of the incision site by the contents due to manipulation at the interface. In addition, a fixing part is provided to further fix the purse-string suture when needed, and the drainage hole with a gradually decreasing diameter along the drainage direction facilitates drainage.

[0025] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0026] Example:

[0027] Please see Figures 1-4 This embodiment provides an intestinal decompression drainage tube, including a first decompression drainage branch tube 1 and a second decompression drainage branch tube 2, wherein the first decompression drainage branch tube 1 and the second decompression drainage branch tube 2 are detachably connected.

[0028] The first pressure-reducing drainage branch tube 1 includes a first branch tube body 102. A pressure-reducing drainage head 101 is provided at one end of the first branch tube body 102 away from the second pressure-reducing drainage branch tube 2. A drainage hole matching the first branch tube body 102 is opened through the pressure-reducing drainage head 101. The outer diameter of the pressure-reducing drainage head 101 is larger than the outer diameter of the first branch tube body 102.

[0029] The shape of the pressure relief drainage head 101 is not specifically limited. It can be mushroom-shaped or other shapes, as long as the minimum outer diameter is greater than the outer diameter of the first branch tube body 102 and the surface is smooth.

[0030] In an optional embodiment, the first pressure-reducing drainage branch 1 and the second pressure-reducing drainage branch 2 are threaded or plugged in.

[0031] In an optional embodiment, a first connecting portion 103 is provided at one end of the first branch tube body 102 near the second pressure-reducing drainage branch tube 2, and a connector 105 is provided on the outer side of the first connecting portion 103. The second pressure-reducing drainage branch tube 2 includes a second branch tube body 202, and a second connecting portion 201 matching the connector 105 is provided at one end of the second branch tube body 202 near the first branch tube body 102. The second connecting portion 201 has a U-shaped structure. Preferably, an operating portion 104 is also symmetrically provided on the outer side of the first connecting portion 103 to facilitate the connection and separation of the first pressure-reducing drainage branch tube 1 and the second pressure-reducing drainage branch tube 2.

[0032] Specifically, when the first pressure-reducing drainage branch pipe 1 and the second pressure-reducing drainage branch pipe 2 are threadedly connected, the outer wall of the connector 105 is provided with a first thread, and the inner wall of the second connecting part 201 is provided with a second thread that matches the first thread. The outer wall of the first branch pipe body 102 is in contact with the inner wall of the second branch pipe body 202, or the first branch pipe body 102 and the second branch pipe body 202 are mated and their inner and outer diameters are equal, or the inner wall of the first branch pipe body 102 is in contact with the outer wall of the second branch pipe body 202. When the first pressure-reducing drainage branch pipe 1 and the second pressure-reducing drainage branch pipe 2 are plugged in, the connector 105 is made of soft material, and the outer diameter of the connector 105 is larger than the inner diameter of the second connecting part 201. The outer wall of the first branch pipe body 102 is in contact with the inner wall of the second branch pipe body 202, or the inner wall of the first branch pipe body 102 is in contact with the outer wall of the second branch pipe body 202.

[0033] In an optional embodiment, a fixing part 106 is also provided at the junction of the decompression drainage head 101 and the first branch tube body 102. The fixing part 106 is used to fix the purse-string suture. The doctor can use the fixing part 106 to further fix the purse-string suture as needed. Optionally, the fixing part 106 is a groove-shaped structure.

[0034] In an optional embodiment, the drainage hole has a diameter-reducing hole structure along the drainage direction to facilitate drainage.

[0035] Please see Figure 4 In one specific embodiment, the pressure-reducing drainage head 101 is mushroom-shaped, and the first pressure-reducing drainage branch tube 1 and the second pressure-reducing drainage branch tube 2 are connected by a Luer connector. The inner wall of the first branch tube body 102 is in contact with the outer wall of the second branch tube body 202.

[0036] It should be noted that, Figures 1-4 The ratio of diameter to wall thickness of each structure in the diagram does not represent the actual ratio, but is only a structural illustration. The specific diameter and wall thickness design of each structure depends on specific requirements.

[0037] In this embodiment, medical staff first select a suitable intestinal decompression drainage tube based on the assessment, then assemble the first decompression drainage branch tube 1 and the second decompression drainage branch tube 2, insert the decompression drainage head 101 into the intestinal lumen, fix the purse-string suture, and perform decompression drainage. When the second decompression drainage branch tube 2 becomes blocked, it is removed and replaced with a new second decompression drainage branch tube 2 of the same model. This embodiment, by setting the decompression drainage head 101, can prevent the main body 102 of the first branch tube from dislodging during intestinal decompression drainage, thus preventing the decompression drainage tube from dislodging and effectively avoiding secondary contamination caused by leakage of intestinal contents. Furthermore, by designing the decompression drainage tube into two parts, the first decompression drainage branch tube 1 and the second decompression drainage branch tube 2, the lengths of the first decompression drainage branch tube 1 and the second decompression drainage branch tube 2 can be designed according to requirements. To reduce the probability of blockage of the first decompression drainage branch tube 1, the lengths of the first decompression drainage branch tube 1 and the second decompression drainage branch tube 2 can be shortened. The length ratio of 2, that is, within a reasonable range, shortens the length of the first decompression drainage tube 1 and lengthens the second decompression drainage tube 2, so that when the decompression drainage tube is blocked, it is highly likely that the second decompression drainage tube 2 will be blocked. Therefore, there is no need to operate on the first decompression drainage tube 1, that is, there is no need to operate on the interface between the decompression drainage tube and the intestinal lumen, effectively avoiding the contamination of the incision by contents due to operation at the interface. In addition, by setting a fixing part 106, the purse-string suture can be further fixed when needed. The drainage hole with a gradually decreasing diameter along the drainage direction facilitates drainage.
