Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, and particularly relates to a bladder irrigation urinary catheter adapter for a double-lumen urinary catheter. Background Art
[0002] Bladder irrigation is one of the common treatment methods in urology, mainly used to remove foreign bodies such as blood clots, pus, and stone fragments in the bladder, prevent infection, and keep the urinary tract unobstructed. When performing bladder irrigation, it is necessary to connect the irrigation fluid bag and the urine bag through a urinary catheter to complete the input of the irrigation fluid and the output of urine. However, traditional bladder irrigation urinary catheters have certain limitations in design. Especially when the urine bag is full and needs to be replaced, urine reflux is likely to occur, which not only increases the discomfort of the patient but also may cause urinary tract infections. In severe cases, it may even lead to the mixing of the irrigation fluid and urine, affecting the irrigation effect.
[0003] Therefore, in the prior art, a stop-flow clip is provided on the urinary catheter, and the urinary catheter is closed by clamping the stop-flow clip outside the urinary catheter to disconnect the connection between the urine bag and the urinary catheter, so as to replace the urine or perform drug irrigation.
[0004] However, in actual use, due to problems such as unbalanced setting positions of the torsion springs of the stop-flow clip, uneven force application at the position of the clip head of the stop-flow clip, or gaps in the closure of the clip head, the clamping and closing of the pipeline from the outside are not tight enough. Especially when the urine bag is replaced and squeezed, the instantaneous high pressure or high flow rate may break through the clamping position, and there is still a risk of urine reflux. Content of the Utility Model
[0005] The purpose of the utility model is to provide a bladder irrigation urinary catheter adapter for a double-lumen urinary catheter to solve the technical problem of urine reflux caused by clamping gaps in the prior art.
[0006] To solve the above technical problem, the utility model specifically provides the following technical solutions:
[0007] A bladder irrigation urinary catheter adapter for a double-lumen urinary catheter includes a main connection pipeline. One end of the main connection pipeline is connected with two independent first pipelines and second pipelines. The first pipeline and the second pipeline are connected to the main connection pipeline in a communicating manner. Among them, a snap connection assembly is arranged on the second pipeline;
[0008] The snap connection assembly includes a plurality of access convex nodes and a plurality of receiving clip grooves arranged inside the second pipeline. The access convex nodes and the receiving clip grooves are arranged in one-to-one correspondence;
[0009] The end of the access convex node is set in a circular arc ball head shape. The middle part of the access convex node contracts inward so that its diameter is smaller than the diameter of the end. The other end of the access convex node is connected to the pipe wall of the second pipeline;
[0010] The upper end of the receiving clamping groove is provided with an opening, and the middle part is provided with clamping edges close to each other for engaging with the middle part of the access convex section. The receiving clamping groove is arranged on the pipe wall of the two branch pipes opposite to the access convex section.
[0011] As a preferred embodiment of the present invention, both the access convex section and the receiving clamping groove are connected to the pipe wall of the two branch pipes through pressure columns. The pressure columns are integrally formed with the pipe wall of the two branch pipes and extend outwards.
[0012] As a preferred embodiment of the present invention, the pipe wall of the two branch pipes includes an inner pipe wall and an outer pipe wall, and both the access convex section and the receiving clamping groove are integrally formed on the inner pipe wall.
[0013] As a preferred embodiment of the present invention, a limiting member is fixedly arranged on the pressure column. The limiting member is arranged above the outer pipe wall and contacts the outer pipe wall.
[0014] As a preferred embodiment of the present invention, the limiting members on the two pressure columns are magnetic attracting sheets with different magnetic polarities.
[0015] As a preferred embodiment of the present invention, a finger ring is arranged on the pressure column.
[0016] The present invention has the following beneficial effects compared with the prior art:
[0017] By arranging an access convex section and a receiving clamping groove inside the two branch pipes, and making the two side pipe walls of the two branch pipes approach each other, the two are connected to each other in an embedded manner, so as to achieve the purpose of closing the two branch pipes. And because they are connected to each other inside the two branch pipes, and there are multiple access convex sections and receiving clamping grooves connected to each other, multiple blocking doors can be formed, so as to achieve the purpose of tightly controlling the closing of the two branch pipes and preventing urine from flowing back through the two branch pipes into the urinary catheter.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] As Figures 1 to 3 shown, the present utility model provides a bladder irrigation urinary catheter adapter for a double-lumen urinary catheter, including a main connection pipeline 1, the main connection pipeline 1 is used to connect with the urinary catheter, and two independent first branch pipelines 2 and second branch pipelines 3 are connected to one end of the main connection pipeline 1. The first branch pipeline 2 and the second branch pipeline 3 are connected and communicated with the main connection pipeline 1. Among them, the second branch pipeline 3 is used to connect the urine bag, and the first branch pipeline 2 is used to connect the liquid medicine syringe. A snap connection assembly 4 is provided on the second branch pipeline 3.
[0027] Among them, the snap connection assembly 4 includes a plurality of access convex joints 5 and a plurality of receiving clamping grooves 6 provided inside the second branch pipeline 3. Specifically, the plurality of access convex joints 5 and the plurality of receiving clamping grooves 6 can be arranged circumferentially around the inner wall of the second branch pipeline 3 (leaving a vacant position on both sides for closing), and the access convex joints 5 and the receiving clamping grooves 6 are arranged in one-to-one correspondence, so that they can better contact and engage with each other when the pipe walls approach.
[0028] The end of the access convex joint 5 is set as an arc ball head shape, the middle part of the access convex joint 5 contracts inward so that its diameter is smaller than the diameter of the end part, and the other end of the access convex joint 5 is connected to the pipe wall of the second branch pipeline 3.
[0029] The upper end of the receiving clamping groove 6 is provided with an opening, and the middle part is provided with clamping edges close to each other for engaging with the middle part of the access convex joint 5. The receiving clamping groove 6 is arranged on the pipe wall of the second branch pipeline 3 opposite to the access convex joint 5.
[0030] Specifically, when pinching the pipe wall at the target position from the outside, at this time, the access convex joint 5 moves towards the receiving clamping groove 6 and is embedded in the receiving clamping groove 6 to complete the closing of the pipeline.
[0031] Furthermore, both the access convex section 5 and the receiving clamping groove 6 are connected to the pipe wall of the two-way pipe 3 through the pressing column 7. The pressing column 7 is integrally formed with the pipe wall of the two-way pipe 3 and extends outward. By providing the pressing column 7, on the one hand, the operator can accurately confirm the positions where the access convex section 5 and the receiving clamping groove 6 are provided from the outside. On the other hand, by using the pressing column 7 to press against the access convex section 5 and the receiving clamping groove 6, it can also make the connection between the two more effective and fast, making it more convenient to use.
[0032] In addition, the pipe wall of the two-way pipe 3 includes an inner pipe wall 31 and an outer pipe wall 32. Both the access convex section 5 and the receiving clamping groove 6 are integrally formed on the inner pipe wall 31. In actual production, the access convex section 5 and the receiving clamping groove 6 can be provided inside the pipe through the pressing column 7, that is, the access convex section 5 and the receiving clamping groove 6 are provided on the pressing column 7, and the pressing column 7 extends into the pipe interior. That is, the access convex section 5 and the receiving clamping groove 6 protrude from the pipe wall. However, when there is liquid flowing in the pipe in this setting method, the liquid will wash the access convex section 5 and the receiving clamping groove 6, making the urine flow not smooth. Therefore, in this device, the inner pipe wall 31 and the outer pipe wall 32 are provided. After the access convex section 5 and the receiving clamping groove 6 are provided on the pipe wall, the contact area with the liquid flow can be reduced, so that the urine flow is smoother.
[0033] As Figure 2 shown, further, a limiting member 8 is fixedly provided on the pressing column 7. The limiting member 8 is provided above the outer pipe wall 32 and contacts the outer pipe wall 32. The setting of the limiting member 8 can drive the outer pipe wall 32 to move synchronously through the limiting member 8 when the inner pipe walls 31 approach each other, so as to prevent the inner pipe wall 31 and the outer pipe wall 32 from spacing apart to form a large crack.
[0034] As Figure 2 shown, the limiting members 8 on the two pressing columns 7 are magnetic attraction sheets with different magnetic polarities. The setting of the magnetic attraction sheets can further apply a clamping force to the target position outside the pipe body to keep the closing degree of this position better.
[0035] Furthermore, a finger ring 9 is provided on the pressing column 7. Inserting a finger into the finger ring 9 for use can make the use method more convenient.
[0036] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
