Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to can remove syringe needle formula syringe safely.
Background
The injector structure used in clinic at present mainly comprises a syringe, a piston connected with the syringe and a pull rod matched with the piston. Medical personnel move the piston by pushing and pulling the pull rod, and realize operations such as dispensing or injection. However, because the needle surface is not provided with a protective device, the needle and the needle cylinder are in a separated state, and the like, medical staff often connects the needle and the needle cylinder before use and separates the needle and the needle cylinder after use to cause occupational exposure, students who are waiuenza and the like carry out needle stick injuries investigation on 200 nurses, and as a result, the proportion of the patients with the 90 nurses with different needle stick injuries is the largest because 33.3% of the nurses are caused by improper treatment after the injection is used (waiuenza, nursing staff work has the analysis and countermeasure on the needle stick injuries reasons [ J ]. China contemporary medicine, 2013,20(010):168 plus 169.). In order to allow medical personnel to safely and effectively dispose of the needle before and after use, a need exists for a syringe that provides for safe and convenient needle removal.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a simple structure, convenient operation's syringe needle formula syringe can remove safely to solve medical personnel and expose the problem clinically in the occupation that takes place in the use syringe process, reduce the acupuncture incidence of hindering.
The utility model provides a technical scheme as follows:
a safety removable needle injector comprising a needle, a barrel, a piston, a pull rod and a needle removal housing;
the needle head, the needle cylinder, the piston and the pull rod form an injector main body;
the outer wall of the needle cylinder is provided with a limiting column in a radial direction;
the needle head removing shell is a conical shell and covers the upper part of the needle cylinder, and the head end of the needle head removing shell gradually shrinks to the lower end of the needle head; the inner wall of the needle removing shell is provided with a thread groove, and the end part close to the lower end of the needle is provided with a baffle plate;
the thread groove is used for being clamped into the limiting column so as to realize the rotary lifting of the needle head removing shell.
Furthermore, the limiting column is a cylinder which is perpendicular to the wall of the needle cylinder.
Further, the needle removing housing head end is close to the syringe nipple.
Further, the thread groove comprises a first groove and a second groove, the two grooves are arranged in parallel and are respectively clamped into the limiting columns on the two sides.
Furthermore, the baffle is the annular plate, and the external diameter slightly is greater than the needle file bottom surface.
Further, the needle removing housing ejects the needle by rotating upward.
Further, the needle removing shell is made of transparent and anti-skidding materials.
The utility model has the advantages as follows:
1. the needle removing shell ejects the needle in a rotating and lifting mode, the operation method is simple, the needle can be removed in a non-contact manner, the risks that the needle is exposed in the air and medical staff directly contact the needle are greatly reduced, and the occurrence of needle stick injuries is prevented;
2. the needle head removing shell is made of transparent anti-skidding materials, so that the reading of the injector is not influenced, and adverse events such as slippage and the like in the processes of dispensing, injecting and other operations can be avoided;
3. the utility model discloses simple structure, low in cost utilizes popularization and application.

FIG. 2 is a block diagram of the needle removal housing;
reference numerals are as follows: 1-needle head, 2-needle cylinder, 3-needle head removing shell, 31-needle head removing shell head end, 32-baffle, 33-first groove, 34-second groove and 4-limiting column.
Detailed Description
The present invention will be further described with reference to specific embodiments, but the present invention is not limited thereto.
Fig. 1 shows the structure of the present invention, a safety removable needle syringe, comprising a needle 1, a barrel 2, a piston, a pull rod and a needle removing housing 4.
The syringe needle 1, the syringe 2, the piston and the pull rod form a syringe body.
The outer wall of the needle cylinder 2 is provided with 2 limiting columns 4 in a radial direction oppositely. The limiting column is a cylinder which is vertical to the wall of the needle cylinder.
The needle removing shell 4 is a conical shell covering the upper part of the needle cylinder 2, and the head end 31 gradually shrinks to the lower end of the needle 2 and is tightly attached to the nipple of the needle cylinder, so that the head end can be more easily inserted into the joint of the needle seat and the nipple, and the subsequent ejection of the needle 1 is facilitated. The inner wall of the needle removing shell 4 is provided with 2 thread grooves, namely a first groove 33 and a second groove 34, the two grooves are arranged in parallel and are respectively clamped into the limiting columns on the two sides, and the limiting columns are respectively arranged in the respective grooves. The needle removing housing 4 is provided with a baffle 32 at the end near the lower end of the needle, the baffle being an annular plate having an outer diameter slightly larger than the bottom surface of the needle holder to increase the force-bearing area and make the pushing open easier. The needle removing housing 4 is made of a transparent and non-slip material.
The thread groove is used for being clamped into the limiting column, and the needle head removing shell is lifted up to eject the needle head through rotation so as to realize the rotation lifting of the needle head removing shell.
The using method comprises the following steps: after the normal injection is completed, the needle removing housing 4 is rotated to be raised, the head end 31 of the needle removing housing is inserted into the joint between the needle holder and the nipple, the needle is loosened, and the needle 2 is ejected by the force of the baffle 32. There is no direct contact with the needle 2 throughout the needle removal process.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
