Abstract
The utility model discloses a novel injector, wherein a branch tube (5) communicated with a needle tube (1) is arranged at the bottom part of one side of the needle tube (1) adjacent to a needle head (2), a liquid inlet one-way valve (6) is arranged in the needle head (2), a liquid outlet one-way valve (7) is arranged in the branch tube (5), a branch tube needle head (8) is arranged at the rear end of the branch tube (5), and an elastic compressible medical latex sleeve (9) is arranged in the needle tube (1). With the arrangement, time and labor are saved for medical staff in dispensing medicine, the working efficiency is improved, and the medicine use safety for patients can be ensured as well.
Description
Technical field
This utility model relates to a kind of medical instruments, relates in particular to a kind ofly to make up a prescription conveniently, guarantee that free of contamination novel the making up a prescription of medicine use syringe.
Background technology
At present, for needs intramuscular injection or intravenous patient, when medical personnel make up a prescription for such patient, generally be to adopt to suck liquid medicine bottle with syringe earlier, then the liquid medicine bottle injection that is sucked is entered in the solid powder syringe and medicine bottle, allow solid powder medicine administered by injection product be dissolved in and carry out intramuscular injection or intravenous injection in the liquid drug again.This mode usually needs repeatedly to suck circularly and inject, when especially injecting multiple medicine for needs, increase medical personnel's work burden on the one hand, make medical personnel's fatigue easily, especially upper limb fatigue, on the other hand, piston constantly advances release, medical personnel on hand or pollutant such as airborne antibacterial be easy to pollute medicine, influence the therapeutic effect of medicine, even can make patient suffer from new disease, strengthened patient's health and economic loss.
The utility model content
The purpose of this utility model just is to provide a kind of free of contamination novel making up a prescription of medicine of conveniently making up a prescription, guarantee that addresses the above problem to use syringe.
To achieve these goals, the technical solution adopted in the utility model is such: this novel injector comprises needle tubing, syringe needle, piston and push rod, side bottom near syringe needle on the described needle tubing is provided with being in charge of of being communicated with needle tubing, be provided with the feed liquor one-way valve in the described syringe needle, be provided with the fluid one-way valve in being in charge of, be in charge of end and be provided with and be in charge of syringe needle.
As preferred version: be provided with an elastic compressible medical latex cover in the described needle tubing, the front end of rubber finger sleeve is fixed on the inwall of needle tubing front end, is in charge of between the front end of needle tubing front port and rubber finger sleeve, and the front end of push rod is fixed in the rear end of rubber finger sleeve.
Compared with prior art, advantage of the present utility model is: medical personnel are when using this syringe to make up a prescription, can insert in the infusion bottle being in charge of syringe needle, the pulling push rod, medicinal liquid enters needle tubing by the feed liquor one-way valve, promote piston then, medicinal liquid enters infusion bottle by the fluid one-way valve, simultaneously, medicinal liquid remains on the compressible medical latex cover the inside in the needle tubing, no matter how many times push-and-pull piston, medicinal liquid can not contact with the external world, such setting both can make the medical worker time saving and energy saving when making up a prescription, and increased work efficiency, and can guarantee patient's drug safety again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1:
Referring to Fig. 1, comprise needle tubing 1, syringe needle 2, piston 3 and push rod 4, on the needle tubing 1 near a side bottom of syringe needle 2 be provided be communicated with needle tubing 1 be in charge of 5, be provided with feed liquor one-way valve 6 in the syringe needle 2, be in charge of and be provided with fluid one-way valve 7 in 5, be in charge of 5 ends and be provided with and be in charge of syringe needle 8; Be provided with an elastic compressible medical latex cover 9 in the needle tubing 1, the front end of rubber finger sleeve 9 is fixed on the inwall of needle tubing 1 front end, is in charge of 5 between the front end of needle tubing 1 front port and rubber finger sleeve 9, and the front end of push rod 4 is fixed in the rear end of rubber finger sleeve 9.
Medical personnel are when using this syringe to make up a prescription, can insert in the infusion bottle being in charge of syringe needle 8, pulling push rod 4, medicinal liquid enters needle tubing by feed liquor one-way valve 6, promote piston 3 then, medicinal liquid enters infusion bottle by fluid one-way valve 7, simultaneously, the compressible medical latex that medicinal liquid remains in the needle tubing 1 overlaps 9 the insides, no matter how many times push-and-pull piston, medicinal liquid can not contact with the external world, and such setting both can make the medical worker time saving and energy saving when making up a prescription, increase work efficiency, can guarantee patient's drug safety again.
