Description

Heparin cap opener

Technical Field

The utility model relates to the technical field of medical auxiliary appliances, in particular to a heparin cap opener.

Background

Clinically, the heparin cap is a matched joint device containing heparin components, is mainly used for operations such as vein indwelling needle, central venous catheter catheterization and the like, and can effectively reduce repeated skin puncture, prolong the service time of the vein indwelling needle, reduce the medical cost of patients and improve the clinical work efficiency. Heparin caps are widely used in medicine, and generally one end of the heparin cap is used for being connected with a catheter in a threaded mode, and the other end of the heparin cap is provided with a rubber plug for inserting a needle, so that liquid can be conveyed into the catheter through the needle.

In the using process of the heparin cap, if the heparin cap is polluted by blood due to improper operation or long-term use, the heparin cap needs to be replaced immediately, so that the anticoagulation effect is prevented or the inflammation infection phenomenon is induced. When the heparin cap is disassembled, the heparin cap is difficult to disassemble by hands due to the fact that the connection force between the heparin cap and the catheter is large due to solidification of input liquid or other reasons and the heparin cap is small, the heparin cap is difficult to hold and apply force, so that the heparin cap is usually clamped by hemostatic forceps to be unscrewed clinically, but the clamping force of the hemostatic forceps is difficult to control, the disassembly is inconvenient, and the catheter is easy to clamp.

The heparin cap opener is convenient to detach the heparin cap, and can avoid clamping the catheter when the heparin cap opener is detached.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the heparin cap opener comprises a positioning sleeve, a spiral structure and a handle; the positioning sleeve is used for being sleeved on the insertion end of the heparin cap; the spiral structure is arranged in the middle of the inner top wall of the positioning sleeve and used for rotating into the latex plug at the insertion end of the heparin cap, a plurality of barbs are arranged on the outer side edge of the spiral structure in a spiral line manner, and each barb bends towards the rotating direction of the spiral structure so as to limit the reverse rotation of the spiral structure relative to the latex plug after the spiral structure rotates into the latex plug; the handle is arranged in the middle of the outer top wall of the positioning sleeve and drives the spiral structure to rotate.

Preferably, the spiral structure is a right-handed spiral rod.

Preferably, the lower end of the screw rod is pointed.

Preferably, the diameter of the locating sleeve is larger than the diameter of the insertion end of the heparin cap, and the height of the locating sleeve is higher than the height of the screw rod.

Detailed Description

The utility model aims at providing a heparin cap opener which is convenient for disassembling a heparin cap and can avoid clamping a catheter when being disassembled. In order to better understand the aspects of the present utility model, the present utility model will be described in further detail with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 4, in a specific embodiment, the heparin cap opener provided by the present utility model includes a positioning sleeve 1, a spiral structure 2 and a handle 3:

the positioning sleeve 1 is in a cylinder shape with one end closed, and the diameter of the positioning sleeve 1 is preferably slightly larger than that of the heparin cap 4, so that the positioning sleeve can be just sleeved on the insertion end of the heparin cap 4, and shaking is prevented.

In addition, the screw structure 2 may be provided as a screw rod, the screw direction of the screw angle of the screw rod is rightward when the screw rod is upright, the upper end of the screw rod is fixedly connected to the middle part of the inner top wall of the positioning sleeve 1, and the lower end of the screw rod is a tip for rotating into the latex plug 41 at the insertion end of the heparin cap 4. It should be noted that the height of the screw rod is preferably smaller than the height of the positioning sleeve 1, so that the screw rod can be completely hidden in the positioning sleeve 1 to prevent the tip of the screw rod from being stabbed; the outer side of the spiral structure 2 is uniformly distributed and fixedly connected with a plurality of barbs 21 along the spiral line, and each barb 21 is bent towards the rotation direction of the spiral structure 2 so as to limit the reverse rotation of the spiral structure 2 relative to the latex plug 41 after the spiral structure 2 rotates into the latex plug 41; specifically, the barb 21 may be provided in a triangular pyramid shape, and one of the side surfaces of the barb 21 is inclined toward the rotation direction of the spiral structure 2, so that the contact area between the curved portion of the barb 21 and the latex plug 41 can be increased, thereby further restricting the reverse rotation of the spiral structure 2.

In addition, the handle 3 is arranged in the middle of the outer top wall of the positioning sleeve 1 so as to drive the spiral structure 2 to rotate. Specifically, the handle 3 may be set to include a handle rod 31 and a connecting rod 32, one end of the connecting rod 32 is fixedly connected to the middle part of the outer top wall of the positioning sleeve 1, the other end is fixedly connected to the middle part of the handle rod 31, and the screw structure 2 can be driven to rotate by rotating the handle rod 31 through the connecting rod 32 and the positioning sleeve 1.

The working process and principle of the utility model are as follows:

when the heparin cap 4 needs to be disassembled, the positioning sleeve 1 is sleeved on the insertion end of the heparin cap 4; then one hand fixes the heparin cap 4, and the other hand rotates the handle rod 31 and simultaneously presses the handle rod 31 downwards, so that the spiral structure 2 rotates into the latex plug 41 at the insertion end of the heparin cap 4 under the drive of the connecting rod 32 and the positioning sleeve 1; the handle 31 is reversely rotated, and the spiral structure 2 cannot rotate relative to the latex plug 41 due to the limiting effect of the reverse hook 21, so that the heparin cap 4 can be driven to rotate by the reversely rotated handle 31 through the spiral structure 2 to separate the heparin cap 4 from the catheter 5; finally, the utility model, together with the replaced heparin cap 4, is placed in an acetone solution to dissolve the latex plug 41, so that the spiral structure 2 can be taken out, and the utility model can be reused.

The heparin cap opener provided by the utility model is described in detail above. The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present utility model and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the utility model can be made without departing from the principles of the utility model and these modifications and adaptations are intended to be within the scope of the utility model as defined in the following claims.
