Description

Insulin pen syringe needle detacher

Technical Field

The utility model relates to a detacher, concretely relates to insulin pen syringe needle detacher.

Background

Insulin injection is one of the important means for treating diabetes, and when insulin is injected, the insulin is generally injected by an insulin pen or an insulin pump, and the insulin pen is cheap compared with the insulin pump, so that the application range of the insulin pen is wider. When the insulin pen is used, a needle needs to be installed on the insulin pen core, and insulin in the insulin pen core is injected into a human body through the needle after the needle penetrates into the skin. After insulin injection, the needle on the insulin pen needs to be detached so as to respectively treat the insulin pen core and the needle. At present, when the needle head is disassembled, the needle head is mostly disassembled by bare hands. When the syringe needle is disassembled, the syringe needle is easy to pierce the skin, because the syringe needle needs to pierce the human body in the using process, germs (viruses and bacteria) in the human body are easy to remain on the syringe needle, and when the syringe needle pierces the skin of other people, the germs on the syringe needle are easy to infect the bodies of other people, so that the medical exposure is caused, therefore, the syringe needle detacher for insulin pen injection is necessary to be designed to solve the problems.

In the figure: 1. the device comprises an assembly shell, 2 parts of an extrusion block, 3 parts of a clamping block, 4 parts of a protection head, 5 parts of a guide groove, 6 parts of a guide rail, 7 parts of an assembly groove, 8 parts of a support bolt, 9 parts of a reset spring.

Detailed Description

The insulin pen syringe needle detacher is composed of an assembly shell 1, an extrusion block 2 and a clamping block 3, wherein a protection head 4 is arranged at the left end of the assembly shell 1, the upper end of the protection head 4 is in a conical shape with an opening at the bottom, the lower end of the protection head 4 is in a cylindrical shape, and the protection head 4 is used for isolating the syringe needle of the insulin pen from the outside through the protection head 4 when the syringe needle of the insulin pen is inserted into the protection head 4, so that the syringe needle of the insulin pen cannot be contacted with the skin, the syringe needle of the insulin pen cannot puncture the skin, and the risk of medical exposure is effectively reduced; the right end of the assembly shell 1 is provided with extrusion blocks 2 in an up-down symmetrical shape, guide rails 6 are respectively arranged on the assembly shell 1 at two sides of the extrusion blocks 2, and the extrusion blocks 2 are in sliding connection with the guide rails 6; the guide rail 6 is used for limiting the extrusion block 2, so that the extrusion block 2 can only move along the guide rail 6 under the action of external force, and further the extrusion block 2 is not easy to deviate when moving, and the direction of the force applied to the outside by the extrusion block 2 is always consistent.

A guide groove 5 is formed in the assembling shell 1 between the extrusion block 2 and the protection head 4, a clamping block 3 is movably mounted on the guide groove 5, the contact end of the extrusion block 2 and the clamping block 3 is made into an inclined plane shape, and the inclined plane-shaped end part of the extrusion block 2 can slide on the contact end of the clamping block 3; the purpose that the contact end of the extrusion block 2 and the clamping block 3 is made into an inclined plane shape is as follows: when the extrusion blocks 2 at the upper end and the lower end of the assembly shell 1 move towards the central axis of the assembly shell 1 under the extrusion of external force, the extrusion force in the vertical direction of the extrusion blocks 2 is converted into the thrust in the horizontal direction of the clamping block 3 through the inclined planes at the ends of the extrusion blocks 2, so that the extrusion blocks 2 can push the clamping block 3 to move towards one side of the protection head 4 under the action of the inclined planes at the ends of the extrusion blocks 2, and the clamping block 3 is pushed to clamp the needle head in the protection head 4; the guide groove 5 is used for keeping the moving direction of the clamping block 3 and keeping the direction of the force applied to the outside by the clamping block 3 in the movement of the clamping block 3, so that the direction of the force applied to the outside by the clamping block 3 is always consistent, the direction of the force applied to the needle head by the clamping block 3 is further ensured to be consistent, and the phenomenon that the acting force on the needle head is reduced due to the change of the direction of the acting force on the needle head is avoided.

The assembly shell 1 at two sides of the clamping block 3 is inserted with a supporting bolt 8, one end of the supporting bolt 8 is fixed on the assembly shell 1, the other end of the supporting bolt 8 extends into the assembly groove 7, and a reset spring 9 is arranged in the assembly groove 7 at the right side of the supporting bolt 8 so as to push the clamping block 3 to reset through the reset spring 9, thereby avoiding the clamping block 3 from blocking the protection head 4 and ensuring that the needle head of the insulin pen can be always conveniently inserted into the protection head 4; support bolt 8's effect is to supporting reset spring 9, make clamp splice 3 when moving to protection head 4, can with support bolt 8 cooperation compression reset spring 9, and then make reset spring 9 energy storage under clamp splice 3 and support bolt 8's effect, thereby make reset spring 9 can promote clamp splice 3 after the energy storage and reset, simultaneously because support bolt 8 is connected with assembly shell 1 cartridge, make support bolt 8 can extract and insert by assembling shell 1, and then be convenient for clamp splice 3 and assembly shell 1's assembly and dismantlement.

When the insulin pen injection needle detacher works, the needle of the insulin pen is inserted into the protective head 4; after the needle head is inserted in place, the right end of the assembly shell 1 is held tightly, the extrusion blocks 2 at the upper end and the lower end of the assembly shell 1 are extruded by the force of hands, the extrusion blocks 2 are extruded into the assembly shell 1, the extrusion blocks 2 push the clamping blocks 3 to move towards the protective head 4, and in the moving process of the clamping blocks 3, the clamping blocks 3 are matched with the protective head 4 to clamp the needle head of the insulin pen; after the clamping block 3 clamps the needle of the insulin pen, the extrusion force of the hand on the extrusion block 2 is kept, so that the clamping force of the clamping block 3 on the needle of the insulin pen is kept, the assembly shell 1 is lifted upwards, the assembly shell 1 drives the clamping block 3 to move, and the needle is driven to be separated from the insulin pen core through the clamping block 3; after the needle head of the insulin pen is detached, the extrusion block 2 is released, the extrusion block 2 does not extrude to push the clamping block 3 any more, the clamping block 3 resets towards the right end of the assembly shell 1 under the action of the reset spring 9, and the clamping block 3 reversely pushes the extrusion block 2 to reset in the resetting process; after the clamp block 3 is reset, the pinhead of the insulin pen is poured out from the protective head 4, and the disassembly is completed.

The above description is only a specific embodiment of the present invention, and the above illustration is not to be construed as limiting the essential contents of the present invention, and those skilled in the art can modify or modify the above specific embodiment after reading the present specification without departing from the spirit and scope of the present invention.
