Description

Technical Field

[0001] This utility model belongs to the field of urinary catheter technology, and specifically relates to a double-lumen urinary catheter with graduations. Background Technology

[0002] The rigidity and fixation of urinary catheters can cause discomfort during removal, especially after prolonged use, as adhesions may form between the catheter and the urethra, increasing pain during removal. This pain primarily stems from friction, damage, and potential inflammation between the catheter and the urethral mucosa. Conventional solutions to this problem include using lubricants to reduce friction or providing appropriate analgesia before catheter removal. However, these methods have several drawbacks in practical application. Firstly, lubricants may not effectively resolve adhesions, and improper use could increase the risk of infection. Therefore, we aim to design a novel catheter structure to address this issue. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a graduated double-lumen urinary catheter to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a graduated double-lumen catheter, comprising: a drug delivery component, a catheterization component, and a three-way valve.

[0005] The catheterization assembly includes an injection tube and a catheter body. The right front end of the catheter body is integrally provided with an injection tube for injecting saline. In actual use, the drug delivery assembly is a commonly used medical injection device. As long as it meets the requirement of quantitative injection, it is sufficient. Existing equipment models on the market can be selected according to the needs.

[0006] In a preferred embodiment, the three-way valve has an independent delivery chamber on its left side, and the front side of the independent delivery chamber is connected to the left side interface of the three-way valve.

[0007] In a preferred embodiment, the outer wall of the catheter body is provided with scale lines for easy viewing of the insertion depth, the middle of the catheter body is provided with a drainage cavity for urinary drainage, and the rear end face of the catheter body is integrally provided with a guide head for reducing insertion resistance.

[0008] In a preferred embodiment, the upper and lower sides of the rear end of the catheter body are respectively radially inwardly formed with drainage ports for drainage, and both drainage ports are connected to the rear end of the drainage cavity.

[0009] In a preferred embodiment, a water injection cavity is provided on the lower side of the catheter body, a water balloon is provided on the outer wall of the rear end of the catheter body, a bladder cavity is provided inside the water balloon, the end of the water injection cavity is connected to the bladder cavity, and the front end of the water injection cavity is connected to the inside of the injection tube.

[0010] In a preferred embodiment, the upper interior of the catheter body is provided with a drug delivery chamber for delivering medication. The front end of the drug delivery chamber is connected to the rear end of the independent delivery chamber on the left side of the three-way valve. The drug delivery chamber can deliver analgesics or anesthetics, which help reduce the patient's pain during catheter removal, to the designated location, thus helping to reduce the patient's pain during catheter removal.

[0011] In a preferred embodiment, a collecting cavity is provided inside the rear side of the catheter body. The collecting cavity is an arc-shaped structure cavity. Multiple evenly distributed outflow holes are provided on the outer wall of the rear side of the catheter body. All of the multiple outflow holes are connected to the collecting cavity.

The drug delivery component can be quickly disassembled and assembled through the connecting pipe and the three-way valve, improving the ease of use of the entire device.

[0013] The catheterization assembly features graduated lines on the outer wall of the catheter body, allowing operators to easily determine the insertion depth and reducing the difficulty of insertion. The water-filled balloon and inflation chamber, along with the infusion tubing, prevent the entire catheter from detaching by inflating the balloon. The upper interior of the assembly includes a drug delivery chamber, a collection chamber, and an external drainage port. When catheter removal is needed, the user first delivers analgesic or anesthetic medication through the drug delivery assembly into the independent delivery chamber of the three-way valve via the connecting tubing. Since the front end of the drug delivery chamber is connected to the rear end of the independent delivery chamber on the left side of the three-way valve, the medication enters the collection chamber (see the instruction manual for details on the structure of the collection chamber). Figure 5 The device delivers medication to the bladder outlet via multiple drainage holes connected to the collection chamber. During the medication's effect, the user can remove the catheter using normal operating procedures, which helps reduce the patient's pain during catheter removal. In addition, during normal use, anti-inflammatory drugs can also be delivered through the medication delivery chamber, collection chamber, and drainage holes to avoid inflammation caused by prolonged use and reduce the chance of inflammation during catheterization.
