Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an intermittent urinary catheter clamp. Background Art

[0002] A urinary catheter is a tube inserted from the urethra into the bladder to drain urine, usually made of rubber, silicone rubber or polyvinyl chloride. Its main purpose is to help patients urinate. Usually when the catheter is removed, it needs to be clamped to prevent reflux because urine is easy to reflux. This is usually achieved by using a specific clip or valve so that the catheter can be easily opened or closed when needed.

[0003] At present, when medical staff, patients themselves, or family members and nurses remove the urinary catheter for patients, they usually fold the catheter to prevent urine from flowing back. However, the tube clamps in the prior art are usually locked on one side, and the urinary catheter is squeezed and closed by a movable arm with a protruding part. In actual use, the blocking effect of the urinary catheter is not ideal. In view of this, we propose an intermittent urinary catheter clamp. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide an intermittent catheter clamp to solve the technical problem that the current tube clamp is usually locked on one side, and the catheter is squeezed and closed by a movable arm with a protruding part, which has an unsatisfactory blocking effect on the catheter in actual use.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing an intermittent urinary catheter clamp, including a ring;

[0006] A locking arm A and a locking arm B are symmetrically configured on one side of the collar, and a locking plate is configured on one end of the locking arm B away from the collar, and two hooks are symmetrically configured on one end of the locking plate away from the locking arm B, and a hanging ear that cooperates with the two hooks is configured on one end of the locking arm A away from the collar, and the locking arm A and the locking arm B have two states: closed and open;

[0007] The locking arm A and the locking arm B are both provided with a convex seat on one side of the facing surface, and the facing ends of the two convex seats are both provided with an arc-shaped clamping key, and the locking arm A and the locking arm B push the two convex seats provided with the arc-shaped clamping keys to achieve the closing action of the catheter from both sides;

[0008] The locking arm A and the locking arm B are both provided with a through hole connected to the collar at one end, and the locking plate is provided with a through groove in the center on one side facing the locking arm A.

[0009] Preferably, the through groove and the through hole are located on the same axis, and both the through hole and the through groove are used for the urinary catheter to pass through.

[0010] Preferably, the through groove is a U-shaped groove with an opening on one side, the through groove and the through hole are located on the same axis, and both the through hole and the through groove are used for the catheter to pass through.

[0011] Preferably, a clamping piece is centrally constructed at one end of the locking arm A facing the hook, and the clamping piece is slidably disposed in the through slot, and the clamping piece cooperates with the through slot to form a pre-tightening cavity for secondary closing of the catheter.

[0012] Preferably, the locking arm A and the locking arm B are both made of flexible plastic material, and the opposite ends of the locking arm A and the locking arm B away from the collar are both configured with anti-slip grooves.

[0013] Preferably, the locking arm A and the locking arm B maintain an angle of thirty degrees during the opening and closing action, and the locking arm A and the locking arm B remain parallel during the closing action.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model clamps and fixes the urinary catheter from both sides by pushing two convex seats with arc-shaped clamping keys through the locking arm A and the locking arm B. Since the contact area of ​​the two arc-shaped clamping keys on the urinary catheter is small, the problem of catheter sealing failure caused by pulling can be avoided with the bilateral clamping and fixing, which greatly improves the sealing effect of the urinary catheter.

[0016] 2. After the utility model completes the clamping of the urinary catheter by two convex seats provided with arc-shaped clamping keys, the two hooks provided at one end of the locking plate are connected to the hanging ears at one end of the locking arm A, and the clamping piece is inserted into the through groove. The urinary catheter is further clamped by the pre-tightening cavity formed by the clamping piece and the through groove, thereby further ensuring the blocking effect of the urinary catheter.
