Description
Technical field
This utility model belongs to technical field of medical instruments, specifically, when relating to inject, the disposable syringe needle that makes up a prescription of the side opening type that aspiration medicinal liquid is used from air-tight bottle.
Background technology
Medicinal liquid in the syringe pump air-tight bottle is the basic nursing operation of using always, also is for finishing the back work that treatment is done.Carrying out intravenous the time, needing at first from air-tight bottle or ampoule bottle, extract medicinal liquid, injecting supporting agent (as normal saline) then, again it is being acted on patient's human body.
About the medicinal liquid in the suction air-tight bottle, the program that " basic nursing " introduced is such: remove the core of aluminium lid, behind the routine disinfection, the syringe needle that will make up a prescription inserts bottle stopper, toward the air of the interior injection of bottle with required medicinal liquid equivalent, to increase pressure of the inside of a bottle, avoid forming negative pressure, then aspiration medicinal liquid.Cao Fang, Zhao Hua find this method can be in bottle residual liquor, a kind of modification method has been proposed, being about to syringe needle inserts in the air-tight bottle, the right hand is held syringe needle slope is 45 ~ 50 jiaos downwards, left hand is held air-tight bottle and is 15 ~ 20 jiaos, while rotating the suction withdraw of the needle, withdraw of the needle speed slow slightly (packet header medical college journal, 2002 the 18th the 1st phases of volume) when aspiration medicinal liquid closes to an end.Efficient is low, the shortcoming of vulnerable to pollution but applicant's discovery, the method for this improvement exist.
The applicant further discovers, the problem that exists in the aspiration medicinal liquid process, its syringe needle that makes up a prescription that has its source in.
The existing syringe needle that makes up a prescription is the disposable syringe needle that makes up a prescription of side opening type, comprises pin stalk and pintle, and pin stalk length is 30mm, main body is hollow, and front end is the needle point of filled circles cone, establishes a side opening apart from front end a distance and is used to pass in and out medicinal liquid, pin stalk rear end is a pintle, is used for syringe supporting.The mentality of designing of this syringe needle is that the point of pumping liquid is low more good more, so designed long pin stalk, hope can reach the air-tight bottle bottom as far as possible.But in fact because the existence of needle point, the side opening on the pin stalk is impossible arrive the air-tight bottle bottom, and the sectional area of adding the air-tight bottle bottom is certainly greater than the bottle stopper place, and in the operation of historical facts or anecdotes border, user all reverses air-tight bottle the certain angle suction; Just aforesaid modification method.
And the applicant finds, even use described modification method, still has other technical problem.Distance, the dynamics that problem is the withdraw of the needle is not easy control, and the withdraw of the needle exactly in aspiration procedure than rerum natura differences such as higher, the viscositys of medicinal liquid, also is different to the requirement of operation technique to operator's requirement; In the practical operation, often need inserting needle, the withdraw of the needle repeatedly could be extracted into medicinal liquid preferably.Even more serious problem is that pin stalk meeting friction bottle stopper might be brought some microgranule foreign bodies in the air-tight bottle into, thereby pollute medicinal liquid in the process of forward and back pin, damages patient health or even causes malpractice.
The utility model content
The purpose of this utility model provides the disposable syringe needle that makes up a prescription of a kind of side opening type, can make the operator extract medicinal liquid efficiently and safely from air-tight bottle.
For realizing this utility model purpose, the technical scheme that is adopted is such: the disposable syringe needle that makes up a prescription of side opening type, comprise pin stalk and pintle, pin stalk main body is hollow, front end is the needle point of filled circles cone, establishes a side opening apart from front end a distance and is used to pass in and out medicinal liquid, and pin stalk rear end is a pintle, be used for syringe supportingly, it is characterized in that: pin stalk side opening apart from the distance of pintle less than 10mm.
Further, pin stalk length is less than 18mm.
As the technical scheme of the best, pin stalk length is 14-16mm, and pin stalk side opening is 5-8mm apart from the distance of pintle.
The applicant finds that through a large amount of investigations the bottle stopper thickness of air-tight bottle is 3-4mm substantially, and pin stalk length just can be pricked at 5mm and be worn bottle stopper; Similarly, pin stalk side opening has 5mm apart from pintle, just can penetrate bottle stopper and arrive liquid level.On this basis, pin stalk side opening is near more apart from the bottle stopper inboard, the medicinal liquid that just can exhaust more, so the applicant has made this utility model.
This utility model has shortened pin stalk length and the side opening distance apart from pintle, so but one-time-reach-place when aspiration medicinal liquid does not need the withdraw of the needle, and utilize the negative pressure just to pump medicinal liquid, aspirate and extract syringe needle after finishing and get final product.More convenient operation has reduced the residue medicinal liquid on the one hand; The more important thing is does not need the repeated friction bottle stopper, thereby has avoided the contamination accident generation.In addition, shorten pin stalk length and also can save raw material, according to measuring and calculating, the existing syringe needle unit price that makes up a prescription is 0.17 yuan, shortens length and can save 0.03 ~ 0.05 yuan of the prices of raw and semifnished materials.As seen, this utility model has social benefit and economic benefit concurrently.
