Description

Needle head and syringe separator with crowbar

Technical Field

The invention relates to a medical injector and a needle separating tool, in particular to a needle syringe separator with a crowbar.

Background

After the syringe is used, the needle and the barrel are often separated and then separately processed. In the prior art, a needle head is usually pulled out manually by a person, and if the operation is careless, the needle head can be punctured and hurt, and germs of a patient can be possibly carried, so that great potential safety hazards are caused to the safety of medical staff. Chinese patent application No.: 201310749963.7, 'multifunctional needle syringe separator', including the box, has mutually independent first collection chamber and second collection chamber on the box, and the top in first collection chamber is equipped with the baffle, has seted up the syringe needle separation hole on the baffle, thereby the syringe needle separation hole can form the fender to the last connector of medical injector can be with the syringe needle and the syringe separation of syringe when carrying and drawing the syringe barrel. This patent application requires the medical staff to hold the syringe in one hand and exert force upwards and to press the case in the other hand and exert force downwards. If the needle cylinder is tightly jointed with the needle head, firstly, the needle cylinder can be laboriously pulled out, and secondly, the needle cylinder can be separated from the hand due to sudden looseness or no tight slipping of the needle head part, so that uncertain harm is brought.

Disclosure of Invention

To further improve the syringe-needle separator, the present invention seeks to provide a crowbar-equipped needle syringe separator.

The technical scheme adopted by the invention for solving the technical problems is as follows: the needle head and syringe separator with crowbar has V-shaped fork hole on the panel of the support, hinged seat fixed beside the V-shaped fork hole, V-shaped fork head of the crowbar and the V-shaped fork hole of the support, and the V-shaped structure direction of the crowbar and the V-shaped fork hole are corresponding and overlapped; the hinged support of the crowbar is connected with the hinged support through a hinged shaft, and the crowbar can swing up and down around the hinged shaft. A needle box is arranged below the bracket. One end of the spring is propped against the upper surface of the bracket, and the other end of the spring is propped against the lower surface of the crowbar. The spring may be a plate spring or a torsion spring. The panel at one end of the bracket with the V-shaped fork hole is higher than the panel at one end close to the tail part of the crowbar.

The working method of the needle head and needle cylinder separator with the crowbar comprises the following steps that a needle cylinder with a needle head is held by one hand, one end with the needle head faces downwards, and the needle cylinder is inserted from the large end of a V-shaped fork hole of a bracket; the lower plane of the needle cylinder is above the plane of the V-shaped fork of the crowbar, and the large end of the needle head is below the panel of the bracket; the joint between the needle head and the needle cylinder is closed to the small end of the V-shaped fork hole, so that the lower surface of the V-shaped fork hole blocks the upper end of the needle head, and the needle head can be prevented from moving upwards; the tail of the crowbar is pressed down by the other hand to enable the crowbar to rotate around the hinge shaft, the V-shaped fork at the other end of the crowbar moves upwards under the action of the lever, the needle cylinder on the V-shaped fork is pushed upwards to enable the needle cylinder to be separated from the needle head, and the needle head falls into the needle box after separation.

The needle head and needle cylinder separator with the crowbar has the advantages that the needle head and the needle cylinder are separated more easily and safely by the lever principle.

Detailed Description

In the figure, a panel of a needle head syringe separator with a crowbar is provided with a V-shaped fork hole 31, a hinge seat 2 is fixed beside the V-shaped fork hole 31, and a V-shaped fork head 11 of the crowbar 1 and the V-shaped fork hole 31 of the bracket 3 are in corresponding V-shaped structural directions and are overlapped; the hinge support 12 of the crowbar 1 is connected with the hinge base 2 through the hinge shaft 7, and the crowbar 1 can swing up and down around the hinge shaft 7. A needle box 4 is arranged below the bracket 3. One end of the spring 8 is propped against the upper surface of the bracket 3, and the other end is propped against the lower surface of the crowbar 1. The panel at one end of the bracket 3 with the V-shaped fork hole 31 is higher than the panel at one end close to the tail of the crowbar 1.

The working method of the needle head syringe separator with the crowbar is that a syringe 5 with a needle head 6 is held by one hand, one end with the needle head 6 faces downwards, and the needle head is inserted from the big end of a V-shaped fork hole 31 of a bracket 3; the lower plane of the needle cylinder 5 is above the plane of the V-shaped fork 11 of the crowbar 1, and the large end of the needle 6 is below the panel of the bracket 3; the joint between the needle 6 and the syringe 5 is closed to the small end of the V-shaped fork hole 31, so that the upper end of the needle 6 is blocked under the V-shaped fork hole 31, and the needle 6 can be prevented from moving upwards; the tail of the crowbar 1 is pressed down by the other hand, so that the crowbar 1 rotates around the hinge shaft 7, the V-shaped fork 11 at the other end of the crowbar 1 moves upwards under the action of the lever, the needle cylinder 5 on the V-shaped fork 11 is pushed upwards, the needle cylinder 5 is separated from the needle head 6, and the needle head 6 falls into the needle box 4 after separation.
