Description
Technical field
This utility model belongs to technical field of medical instruments, is specially a kind of medicine prescription making syringe.
Background technology
Injector for medical purpose divides intramuscular injection syringe and dispensing syringe at present, and both structures and shape are nearly identical, different
Part is both amount of capacity, and dispensing syringe capacity is more than intramuscular injection syringe capacity, exactly because dispensing syringe holds
Amount is relatively big, in dispensing operation process with regard to underaction, requires push-and-pull on the other hand when pushing away medicine and inhaling medicine, and another hands should hold medicine bottle
Holding syringe again, both hands close fit just can complete operation, makes up a prescription and is different from intramuscular injection, pushes away medicine and suction medicine operation need to repeatedly weigh
Multiple, careless slightly will go out to spill liquid, medicine bottle obscission, bring adverse effect to nursery work.The most existing syringe
In use syringe needle is exposed outside, easily stab nursing staff or other people, the whole world has about 1,000,000 every year according to statistics
There is needle stick injuries accident in nursing staff, causes more than 20 kind diseases to I haven't seen you for ages, pricking wound become in nursery work modal
A kind of occupational injury of harm.
Summary of the invention
In order to solve the deficiencies in the prior art, this utility model provides a kind of medicine prescription making syringe.
This utility model be the technical scheme is that a kind of medicine prescription making syringe, including syringe, handle, piston rod,
Piston, spring, entry needle, pintle, needle guard sleeve；
Described syringe is hollow cylindrical, and syringe one end is provided with nipple, and other end opening is also provided with sealing cap at opening part, envelope
Cap center is provided with circular hole；
Described handle is " Jiong " shape, is fixed on syringe opening part；
One end of described piston rod is connected with piston, and upper cover of piston rod has spring, is arranged at after piston rod, piston, spring assembling
In syringe, wherein the other end of piston rod exposes through sealing cap circular hole and is provided with handle on end points；
Described entry needle is sleeved on pintle, and pintle is sleeved on nipple；
Described needle guard sleeve is for folding shape rubber tube, and one end is sealed, and the other end is sleeved on pintle, and entry needle is wrapped up it by needle guard sleeve
In.
Further, described syringe is provided with volume scale.
Further, described injection translucent medical material is made.
Further, described sealing cap is threadably secured with syringe and is connected.
Further, described handle height is less than syringe length.
Further, described handle is provided with anti-skidding salient point.
Further, under described needle guard sleeve free state, its length is slightly larger than entry needle length.
This utility model using method and principle be: the palm of the hand grips handle, forefinger and middle finger clamping handle；When puncturing medicine bottle,
The palm of the hand pushes hard handle, and needle guard sleeve is stayed outside medicine bottle by compression, and entry needle thrusts medicine bottle；When inhaling medicine, forefinger and middle finger are used
Power is pulled outwardly piston rod, and spring is compressed, and medicinal liquid enters syringe under atmospheric pressure；When outwards pulling out pin, the palm of the hand,
Forefinger and middle finger keep original relative status outwards to exert oneself, and needle guard sleeve is automatically wrapped up under elastic reaction and is pulled out entry needle；When pushing away
During medicine, forefinger and middle finger loosen, and piston rod moves downward under compression spring effect automatically, and medicinal liquid is pushed out syringe.
This utility model provides the benefit that: 1. during whole dispensing operation, only needs single-hand operated syringe, and another hands is whole-heartedly
Full meaning operation medicine bottle, i.e. decreases operation easier, reduces again operational error；2. entry needle is provided with needle guard sleeve, and entry needle is except thorn
Enter outside medicine bottle all the time in needle guard sleeve, be prevented effectively from the generation of stick injuries；3. simple in construction, easy to operate, nursing can be alleviated
Personnel labor intensity.
Accompanying drawing explanation
If Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
