Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical supplies, in particular to a convenient catheter valve. BACKGROUND

[0002] As a medical device, the catheter plays a vital role in modern medicine. It is made of natural rubber, silicone rubber or polyvinyl chloride (PVC) and other materials, and its original design is to be inserted into the bladder through the urethra to facilitate the drainage of urine. There are many types of catheters on the market. Among them, the two main designs have their own advantages and disadvantages. The first type of catheter has a urine bag directly connected to the tail end. Although this design is simple, it needs to be pulled out of the patient's body when replacing the urine bag, which not only may bring inconvenience, but also may cause infection during operation, increasing the medical risk of patients. The other design is that the catheter can be left in the patient's body for a long time, and the tail end is connected to the urine bag in a detachable manner. Although this design reduces the risk of infection to some extent, when the urine bag and the catheter are separated, the urine in the catheter may continue to drip, which is not only unhygienic, but also brings inconvenience in use. CONTENT OF THE UTILITY MODEL

[0003] In order to overcome the shortcomings and deficiencies of the prior art and improve the convenience and hygiene level when separating the urine bag and the catheter, the present application provides a convenient catheter valve.

[0004] The convenient catheter valve provided by the present application adopts the following technical scheme:

[0005] A convenient catheter valve, comprising a valve body, the valve body comprising an adjusting part, an interface part and a connecting pipe, a channel is arranged inside the valve body to form a valve channel, the valve channel comprises an adjusting cavity, the adjusting cavity is arranged in the adjusting part, a rectangular groove is arranged on the surface of the adjusting part to form an adjusting groove, a valve assembly is arranged in the adjusting groove and the adjusting cavity, the valve assembly comprises a stop pipe and a stop pipe fixing ring, the stop pipe comprises a stop pipe body and a deformation part integrally arranged at both ends of the stop pipe, a deformation ball is fixedly arranged at the intersection of the stop pipe body and the deformation part, the deformation ball is arranged as a hollow oval ball made of rubber, the stop pipe fixing ring is arranged in two, the two stop pipe fixing rings are fixedly arranged on the inner wall of the adjusting cavity, the stop pipe is arranged as a rubber hose, the stop pipe body is arranged in a cylindrical shape, the surface of the deformation part is arranged as a curved surface, the cross-sectional diameter of the deformation part gradually decreases in the direction away from the stop pipe body, and the end of the deformation part away from the stop pipe body is fixedly welded with the stop pipe fixing ring.

[0006] In a specific implementation scheme, the deformation ball is fixedly arranged in two, the two ends of the deformation ball along the length direction of the deformation ball are fixedly connected with the inner wall of the stop pipe, and a spacing is formed between the two sides of the deformation ball and the stop pipe.

[0007] In one specific implementation, the valve assembly further comprises a sliding sleeve and a handle, one surface of the sliding sleeve is provided as a straight surface to form a connecting portion, and another surface is provided as a curved surface with the same shape as the deformation portion to form a mouth portion, the sliding sleeve is sleeved on both ends of the stop pipe, and the mouth portion is matched with the deformation portion.

[0008] In one specific implementation, the handle comprises a hand-held portion and a sleeve portion, the hand-held portion and the sleeve portion are integrally arranged, the sleeve portion is provided in a circular ring shape, the sleeve portion is fixedly sleeved on the connecting portion, the hand-held portion extends out of the adjusting groove, the hand-held portion is symmetrically arranged at both ends of the sleeve portion, and anti-skid lines are formed on the hand-held portion.

[0009] By adopting the above technical scheme, when the mouth portion of the sliding sleeve slides to the deformation portion, the cross-sectional diameter of the deformation portion gradually decreases, which causes the deformation ball to be compressed, and thus the size of the valve passage is changed. By changing the shape and position of the deformation ball, the flow of urine can be effectively controlled, the structure of the valve is simplified, and the opening and closing of the valve become simple. Because the deformation ball and the stop pipe are both made of rubber material, they have good elasticity and durability, which enables the valve assembly to maintain good working condition during long-term use. The rectangular groove formed on the surface of the adjusting portion forms an adjusting groove, so that the user can directly observe the position and state of the valve assembly. This facilitates user operation and makes the entire urinary catheter valve more easy to understand and use. The two stop pipe fixing rings ensure the stability of the stop pipe in the adjusting cavity and prevent the stop pipe from deviating or shaking during movement. This ensures the smoothness and safety of the urinary catheterization process.

[0010] In one specific implementation, the interface portion is connected at an angle of 90 degrees with the adjusting portion.

[0011] By adopting the above technical scheme, by connecting the interface portion and the adjusting portion at an angle of 90 degrees, the volume of the valve body can be reduced, space can be saved, and use is more convenient.

[0012] In one specific implementation, an outer clamping portion is fixedly arranged outside the interface portion, and the outer clamping portion is provided in a tapered stepped shape.

[0013] By adopting the above technical scheme, the outer clamping portion fixedly arranged outside the interface portion is provided in a tapered stepped shape, which can facilitate the tight clamping of the interface portion and the urinary catheter, thereby ensuring the stability of the interface.

[0014] In one specific implementation, a flared seat ring is fixedly arranged at one end of the connecting pipe close to the adjusting portion, an inner clamping portion is fixedly arranged inside the flared seat ring, and a plug-in interface is formed between the flared seat ring and the connecting pipe.

[0015] By adopting the technical scheme, the inner clamping part in the flared seat ring can be matched with the outer clamping part to form a firm connection, the plug-in interface between the flared seat ring and the connecting pipe is convenient to install and disassemble, and the stability of the overall structure can be enhanced.

[0016] In a specific implementable scheme, a stop ring is fixedly arranged at one end of the connecting pipe away from the adjusting part, and a sealing ring is fixedly sleeved between the flared seat ring and the stop ring.

[0017] By adopting the technical scheme, the sealing ring fixedly sleeved between the flared seat ring and the stop ring can effectively prevent urine leakage and has good sealing performance.

[0018] In summary, the present application has at least one of the following beneficial technical effects:

[0019] 1. The stop pipe is composed of a stop pipe body and a deformation part, the deformation part includes a deformation ball which is an oval ball made of rubber and can be deformed when subjected to pressure to control the flow of urine. A sliding sleeve is sleeved at both ends of the stop pipe, and a bundle port of the sliding sleeve is matched with the deformation part, so that the valve opening degree can be adjusted by sliding. A handle is provided for user operation, and anti-slip patterns are formed on the handle to increase the stability of hand holding. The user can open and close the valve through the handle, close the valve when replacing the urine bag to intercept the urine, and open the valve after replacing the urine bag. The operation process is simple and convenient to use.

[0020] 2. The stability of the valve body is ensured by the arrangement of the stop pipe fixing ring and the flared seat ring, so that deviation or shaking during use is prevented. The tight connection of the connecting pipe and the interface part and the sealing ring fixedly sleeved between the flared seat ring and the stop ring effectively prevent urine leakage and ensure the sanitary safety of use.
