Description

Needle dismounting device

Technical Field

The utility model relates to the field of medical auxiliary articles, in particular to a needle dismounting device.

Background

After the infusion of the patient finishes, generally need the nurse to pull out the needle for the patient, the nurse pulls out the needle and need to separate syringe needle and transfusion system after accomplishing to in throwing into dedicated splendid attire case with the syringe needle, avoid the syringe needle to injure nurse or other people by mistake and cause secondary infection.

Currently, nurses generally use a movable infusion vehicle to place some instruments needed for pulling out needles, such as a needle holding special box and scissors (the scissors are hung at one corner of a treatment vehicle) for separating the needles from an infusion set. When a needle needs to be pulled out, the scissors are taken down from the infusion trolley, the needle head and the infusion apparatus are separated by the scissors, and then the needle head is manually placed into the special needle head containing box, so that the hand of a nurse needs to be directly contacted with the needle head, and the possibility of secondary infection is high.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a needle remover which can reduce the possibility of secondary infection of nurses.

In order to achieve the purpose of the invention, the utility model adopts the technical scheme that:

the needle remover comprises a pressing mechanism and a shell with a lateral opening, wherein a rotating plate which can rotate relative to the shell is arranged on a first inner wall of the shell through a torsion spring, a supporting plate matched with the lateral opening is arranged on a second inner wall of the shell, and one side, close to the rotating plate, of the supporting plate is a limiting surface matched with one end, far away from the torsion spring, of the rotating plate; the pressing mechanism comprises a door-shaped frame which can linearly move up and down along the shell, a first vertical edge and a second vertical edge of the door-shaped frame both penetrate through the top wall of the shell, the part of the first vertical edge and/or the second vertical edge in the shell is provided with an anti-falling bulge, the tail end of the first vertical edge is matched with the top surface of the rotating plate, and one end of the second vertical edge in the shell is provided with a blade matched with the supporting plate; the bottom of the shell is detachably connected with the bottle body with the containing cavity, and the containing cavity is communicated with the inside of the shell after the bottle body is connected with the shell.

The utility model has the advantages that:

when the infusion device is used, a transfusion tube close to the needle head on the infusion device is held, the needle head is inserted into the lateral opening (the front end of the needle head is abutted against the first inner wall of the shell for limiting), then the transverse edge of the door-shaped frame is pressed to move downwards for a certain distance and keep the transverse edge, and the rotating plate rotates clockwise for an angle while the driving blade synchronously moves in the moving process of the door-shaped frame. Wherein, the separation of syringe needle and transfusion system is accomplished in the downward removal of blade, and based on the clockwise rotation of commentaries on classics board, the syringe needle after the separation drops to the holding intracavity of bottle under self action of gravity. And finally, the external force applied to the transverse edge of the door-shaped frame is cancelled, and after the external force is cancelled, the rotating plate rotates anticlockwise for an angle under the action of the torsion spring and stops rotating and is kept under the action of the limiting surface, so that the bottle body is sealed, and the needle head in the bottle body is prevented from being accidentally removed. When the number of needles in the bottle body is too large, the bottle body is disassembled, the separated needles are intensively transferred to the special containing box, and the needle disassembling device can be repeatedly used after the bottle body is installed at the bottom of the shell again.

Therefore, the needle dismounting device provided by the utility model realizes the non-contact separation of the needle head, thereby greatly reducing the possibility of secondary infection of nurses.

Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings so as to facilitate the understanding of the present invention by those skilled in the art. It should be understood that the embodiments described below are only some embodiments of the invention, and not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive step, without departing from the spirit and scope of the present invention as defined and defined by the appended claims, fall within the scope of protection of the invention.
