Description

Rotary type syringe destroying device

Technical Field

The invention belongs to the technical field of syringe destroying devices, and particularly relates to a rotary syringe destroying device.

Background

In order to prevent the used disposable syringes from being used repeatedly to cause cross infection, the national health administration department requires that each medical unit destroys the used disposable syringes on the spot, so as to meet the requirements of 'separation of the needle and the barrel, and destruction of the needle and the barrel'. To achieve this, a number of syringe destroyers have been developed.

At present, people generally adopt a mode of bending a needle of the syringe, such as a syringe destroyer (publication No. CN202539168U) disclosed in chinese patent literature, in which destruction is realized by bending the needle at 90 °. However, the needle is also easily bent back after being bent, and is easily repaired, so that the injector may have the possibility of being reused, and the destruction is not thorough.

Disclosure of Invention

The purpose of the invention is: aims to provide a rotary type syringe destroying device which is used for solving the problems that the existing destroying device has structural defects that only a needle head and a needle cylinder can be destroyed, a push rod and a rubber piston in the needle cylinder cannot be destroyed, and the destroying efficiency is low.

In order to achieve the technical purpose, the technical scheme adopted by the invention is as follows:

a rotary type syringe destroying device comprises a hollow base and a rotary cylinder for inserting a syringe, wherein the syringe comprises a needle cylinder, a liquid outlet end on the needle cylinder, a push rod, a rubber piston and a needle head, notches are formed in two sides of the lower portion of the rotary cylinder, hinged plates are integrally formed on the inner walls of the two sides of the lower portion of the rotary cylinder, hinged shafts are arranged on the outer sides of the two hinged plates, gears are fixedly mounted on the hinged shafts, a cylindrical mounting seat is integrally formed on the hollow base, the mounting seat is of a hollow structure, the inner portion of the mounting seat is communicated with the hollow base, an opening is formed in the top end of the mounting seat, the rotary cylinder penetrates through the opening in the mounting seat, hinged cylinders are arranged on the inner walls of the two sides of the mounting seat, the hinged shafts penetrate through the hinged cylinders, a sliding seat is fixedly mounted on the inner wall of one side of the mounting seat, and a button is slidably mounted in the sliding seat, install compression spring between sliding seat and the button, be equipped with first spacing platform in the fixed button top on the sliding seat, still slidable mounting has the rack in the sliding seat in the button top, rack and gear engagement, fixed mounting has the motor on the mount pad, button and motor electric connection, install the saw bit on the output shaft of motor, the saw bit is located the mount pad, and is located revolving cylinder one side, the central plane of saw bit is in the coplanar with the axis of revolving cylinder.

Further limiting, two clamping plates with arc-shaped cross sections are installed on the other side, corresponding to the saw blade, in the mounting seat, the clamping plates are of a structure with a small upper part and a large lower part, the upper ends of the two clamping plates are located between the two hinged plates, the lower ends of the two clamping plates are fixedly provided with cross rods, and two ends of each cross rod are fixedly connected with the side walls on two sides of the mounting seat respectively. Such structural design, after using the saw bit to accomplish the syringe cutting, anticlockwise rotation syringe for two cardboard upper ends block respectively into the both sides of the play liquid end between syringe needle and the cylinder, continue rotatory syringe, through big end down's cardboard, make the distance between syringe needle and the cylinder crescent, thereby make between syringe needle and the play liquid end not hard up gradually, break away from until syringe needle and play liquid end, drop in hollow base, accomplish the separation between syringe needle and the cylinder.

Further defined, the gear is an incomplete gear. Such structural design, when taking off syringe anticlockwise rotation, the gear does not contact with the rack, but direct anticlockwise rotation pulls laborsavingly.

Further, an extension spring is fixedly arranged between the upper end of the rack and the sliding seat. Such structural design pulls the rack through extension spring, avoids gear and rack to break away from the back, and the rack moves down under the effect of gravity to contact with the button for the motor breaks away from the in-process at the syringe needle, and the motor starts.

Further limiting, a second limiting table is arranged on the sliding seat at the position corresponding to the rack. Due to the structural design, the maximum position of the rack moving upwards is limited by the second limiting table, and the rack is prevented from moving upwards excessively.

Further inject, two the outside of articulated slab all is equipped with spacing post, the inner wall of mount pad both sides all fixedly is equipped with the arc spacing ring platform, spacing post is worn to establish in the spacing ring platform. Such structural design, through spacing post and the mutual matching of arc spacing ring platform, prescribes a limit to the biggest deflection position of rotary drum, avoids rotary drum turned angle too big, causes the spare part damage of self.

Further limit, two arc-shaped plates are fixedly arranged on the two sides of the rotary cylinder at the outer side of the opening. Such structural design shelters from the opening of mount pad through two arcs, avoids the piece departure that produces when the saw bit cuts the syringe.
