Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheter limiting, in particular to a urinary catheter fixing device. Background Art

[0002] The types of catheters include: ordinary catheter: used for disposable non-indwelling catheterization; fungiform catheter: suprapubic cystostomy, cecostomy; pointed catheter: for prostate hypertrophy; metal catheter: for urethral stenosis and failure of ordinary catheterization; balloon catheter: commonly used in clinical practice.

[0003] After the balloon catheter is inserted into the urethra, 10 ml of air or saline is usually injected into the balloon with a syringe to fix the catheter and prevent it from slipping out of the urethra.

[0004] However, balloon catheters usually have no external fixation. Such balloons can usually effectively prevent the catheter from slipping out of the urethra, but cannot effectively prevent the catheter from sliding toward the inside of the urethra; for example, when the patient is lying in bed and changes position, the catheter sometimes moves inward, increasing the chance of urinary tract infection. Utility Model Content

[0005] In view of the above problems existing in the prior art, the technical problem to be solved by the utility model is that the airbag on the existing airbag catheter cannot effectively prevent the catheter from sliding toward the inside of the urethra, thereby increasing the probability of urinary tract infection.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solution: a urinary catheter fixing device, comprising:

[0007] A clamping member; the clamping member has an arc-shaped slot, one end of the two clamping members is hinged, and the other ends of the two clamping members are detachably connected to be fixed on the urinary catheter through the two arc-shaped slots; and

[0008] An elastic abutment member is installed on one side of the two clamping members that is perpendicular to the axis of the arc-shaped slot.

[0009] Preferably, the elastic abutment member is an airbag, and the airbag is provided with an arc-shaped avoidance groove for avoiding the urinary catheter.

[0010] Preferably, both clamping members are provided with an extension portion at one end away from the hinge point; one of the extension portions is provided with a bending portion perpendicular to the extension portion; a clamping member is slidably installed on the bending portion along the extension direction of the extension portion, and a gap is provided between the clamping member and the extension portion for clamping the other extension portion.

[0011] Preferably, the clamping part includes: a lever, a limit block, a paddle and a wedge block; one end of the two levers is vertically fixed on the limit block; the other ends of the two levers are fixedly installed with paddles; a plurality of wedge blocks are fixedly installed on the outer side of the lever, and the plurality of wedge blocks are arranged along the length direction of the lever; a sliding groove is provided on the bending part; the two levers slide through the sliding groove; limiting grooves cooperating with the wedge blocks are respectively provided on opposite sides of the sliding groove; the limiting groove is located on the stroke of the wedge block.

[0012] Preferably, a spring is installed between the two levers.

[0013] Preferably, a friction gasket is detachably installed in the arc-shaped groove on the clamping member.

[0014] Compared with the prior art, the utility model has at least the following advantages:

[0015] In the utility model, after the catheter is inserted into the patient's urethra, the catheter is placed between the two arc-shaped grooves, and then the clamping piece is rotated to clamp the catheter through the two arc-shaped grooves, and the other ends of the two arc-shaped grooves are installed with each other, so as to fix the two clamping pieces on the catheter, thereby fixing the two elastic abutment pieces on the catheter, and the elastic abutment pieces abut against the skin, so as to effectively prevent the catheter from sliding into the urethra.

[0016] In the utility model, when the side surfaces of the two extension parts abut against each other, the paddle is pressed downwards to make the lever slide in the slide groove, thereby pushing the limit block to move, so that the limit block and the two paddles abut against the side surfaces of the extension part, limit the extension part, and at the same time, the wedge block is stuck in the limit groove at the corresponding position; thereby, the installation of the two clamping parts away from the hinge point is realized; when it is necessary to disassemble the two clamping parts away from the hinge point, the paddle is pressed inwards by two fingers, and the paddle drives the lever to bend, thereby separating the wedge block on the lever from the limit groove, so that the lever and the limit block can be slid upwards, and the lever and the limit block are separated from the extension part, thereby the two clamping parts can be rotated to move.

[0017] In the utility model, the clamping piece contacts the urinary catheter via the friction gasket, thereby increasing the friction force between the clamping piece and the urinary catheter, thereby preventing the clamping piece from sliding in the axial direction of the urinary catheter; and by replacing friction gaskets of different thicknesses, it can be suitable for urinary catheters of different diameters.
