Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage tubes, in particular to a bile duct drainage tube. Background Art
[0002] The bile duct drainage tube is a disposable soft catheter used clinically to drain bile after common bile duct incision and exploration. It usually includes a flexible and slender main structure, a head structure that conforms to the curvature of the human bile duct, and several side holes for bile drainage.
[0003] Since the diameter of the conventional drainage tube is relatively small, it is troublesome to connect the drainage tube with the pagoda head of the drainage bag. Therefore, in the prior art, the end of the drainage tube is mostly set to be an open "trumpet" so that medical staff can quickly connect the drainage tube with the pagoda head of the drainage bag.
[0004] However, when medical staff replace the drainage bag, the drainage tube is a latex tube with a certain degree of elasticity. When the drainage tube is pulled out from the pagoda head, the drainage tube will be stretched. During the rebound process of the drainage tube, the bile in the drainage tube often leaks out, causing contamination and is more troublesome to clean. Utility Model Content
[0005] In view of this, the purpose of the utility model is to provide a bile duct drainage tube to solve the problem in the prior art that, during the process of removing the drainage tube from the pagoda head, bile in the drainage tube leaks out, causing pollution and being troublesome to clean.
[0006] The utility model solves the above technical problems through the following technical means:
[0007] A bile duct drainage tube comprises a main body, bile duct sections respectively arranged at both ends of the main body, and an open connector, wherein the open connector is used to connect to a pagoda head, and the open connector comprises an integrally formed blocking section and a connecting section, wherein the blocking section is connected to the main body, and a blocking member is arranged in the blocking section, and when the pagoda head is inserted into the blocking section, the blocking member can fit with the pagoda head to close the gap between the pagoda head and the inner wall of the blocking section, and can bend toward the main body following the pagoda head.
[0008] Furthermore, the blocking member comprises a blocking ring sheet, the outer edge of which is fixedly connected to the inner wall of the blocking section, and a receiving groove is formed between the blocking ring sheet and the inner wall of the blocking section.
[0009] Furthermore, a plurality of the blocking ring pieces are provided, and the plurality of the blocking ring pieces are arranged along the length direction of the blocking section, and an accommodating groove is formed between each of the blocking ring pieces and the inner wall of the blocking section.
[0010] Furthermore, the plurality of blocking ring sheets are interconnected to form a spiral ring sheet, so that the plurality of accommodating grooves are interconnected.
[0011] Furthermore, a reinforcement sleeve is provided on the outer sleeve of the blocking section, one end of the reinforcement sleeve is fixedly connected to the blocking section, and the other end of the reinforcement sleeve is fixedly connected to the main pipe body.
[0012] Furthermore, a convex ring is provided at one end of the reinforcement sleeve close to the main pipe body.
[0013] Beneficial effects of the utility model:
[0014] 1. By setting a blocking piece, when the pagoda head is pulled out from the open connecting head, the blocking piece can fit with the outer wall of the pagoda head, close the gap between the pagoda head and the inner wall of the blocking section, and prevent bile from leaking from the gap between the pagoda head and the inner wall of the blocking section.
[0015] 2. By setting a blocking ring piece and forming a receiving groove between the blocking ring piece and the inner wall of the blocking section, the blocking ring piece can scrape the bile adhering to the outer wall of the pagoda head into the receiving groove to prevent the bile from adhering to the pagoda head.
[0016] 3. By setting up multiple blocking rings, the blocking effect is improved. The multiple blocking rings form a spiral ring. The blocking rings can scrape the bile adhering to the outer wall of the pagoda head into the receiving groove, further reducing the leakage of bile. When the open connecting head is placed vertically, the bile in the multiple receiving grooves can flow back into the main pipe.
[0017] 4. By setting a reinforcing sleeve, when holding the reinforcing sleeve and then pulling out the pagoda head, the stretching amplitude of the blocking section can be effectively reduced, thereby reducing the vibration amplitude of the blocking section and further reducing the bile leakage in the main pipe body.

[0024] like Figure 1-Figure 3 As shown, a bile duct drainage tube of the utility model comprises a main body 1, bile duct segments 2 and an open connector 3 respectively arranged at both ends of the main body 1. The bile duct segment 2, the main body 1 and the open connector 3 are all integrally formed and are all latex tubes. The bile duct segment 2 can be set to a T-shape (such as Figure 1 The shape shown) can also be set to a Y shape or other shapes. This embodiment does not limit the specific shape of the bile duct segment 2.
[0025] The open connector 3 is used to connect the pagoda head 4. Specifically, the open connector 3 includes an integrally formed blocking section 31 and a connecting section 32. The blocking section 31 is connected to the main body 1. A reinforcing sleeve 5 is provided on the outer cover of the blocking section 31. One end of the reinforcing sleeve 5 is fixedly connected to the blocking section 31, and the other end is fixedly connected to the main body 1. The hardness of the reinforcing sleeve 5 is greater than the hardness of the material of the blocking section 31, that is, the elasticity of the reinforcing sleeve 5 is lower than the elasticity of the blocking section 31, which can increase the hardness of the blocking section 31. By holding the reinforcing sleeve 5 and then pulling out the pagoda head 4, the stretching amplitude of the blocking section 31 can be effectively reduced, thereby reducing the vibration amplitude of the blocking section 31 and reducing the bile leakage in the main body 1. In this embodiment, the reinforcing sleeve 5 is integrally formed with a convex ring 51 near the main body 1. The convex ring 51 is used to provide resistance to facilitate the pulling out of the pagoda head 4.
[0026] In this embodiment, a blocking member is provided in the blocking section 31, and the blocking member includes a plurality of blocking ring pieces 6. In this embodiment, the blocking ring pieces 6 are also made of latex material, and the outer edge of the blocking ring piece 6 is fixedly connected to the inner wall of the blocking section 31. A receiving groove 61 is formed between each blocking ring piece 6 and the inner wall of the blocking section 31. The plurality of blocking ring pieces 6 are connected to each other to form a spiral ring piece, so that the plurality of receiving grooves 61 are connected to each other. When the pagoda head 4 is inserted into the blocking section 31, the blocking ring piece 6 can fit with the pagoda head 4 to close the gap between the pagoda head 4 and the inner wall of the blocking section 31, and can bend toward the main body 1 along with the pagoda head 4. When the pagoda head 4 is pulled out from the open connector 3, the blocking ring piece 6 can fit with the outer wall of the pagoda head 4, close the gap between the pagoda head 4 and the inner wall of the blocking section 31, and prevent bile from leaking out from the gap between the pagoda head 4 and the inner wall of the blocking section 31. In this process, the blocking ring piece 6 can scrape the bile adhering to the outer wall of the pagoda head 4 into the receiving groove 61. When the open connector 3 is placed vertically, the bile in the plurality of receiving grooves 61 can flow back into the main pipe 1 to prevent the bile from leaking out.
[0027] The working principle of the utility model is as follows:
[0028] When assembling the pagoda head 4 and the open connector 3, the pagoda head 4 of the drainage bag is inserted into the open connector 3. When the pagoda head 4 fits and squeezes the blocking ring piece 6, the blocking ring piece 6 is forced to bend toward the main body 1 along with the pagoda head 4 and adhere to the inner wall of the blocking section 31. After the pagoda head 4 is inserted into the open connector 3, the connecting section 32 is tightly connected with the pagoda head 4 to prevent the pagoda head 4 from automatically falling off from the open connector 3.
[0029] When the pagoda head 4 and the open connector 3 are disassembled, the blocking ring piece 6 fits against the outer wall of the pagoda head 4 to close the gap between the pagoda head 4 and the inner wall of the blocking section 31. During the continuous movement of the pagoda head 4, the blocking ring piece 6 scrapes the bile adhering to the outer wall of the pagoda head 4 into the receiving groove 61. Then, the open connector 3 is placed vertically, so that the bile in the multiple receiving grooves 61 can flow back into the main body 1 to prevent the bile from leaking out.
[0030] The above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model. The technology, shape, and structure that are not described in detail in the utility model are all well-known technologies.
