Description

Double needle

Technical field

This utility model relates to a kind of medical apparatus and instruments, the syringe needle that especially a kind of clinical preparating liquid or liquid use.

Background technology

Obtaining liq, dissolving will repeatedly be used disposable syringe during injectable powder clinically at present; the pull pintle is operated repeatedly; not only waste time and energy; and pintle has increased the probability of polluting in the process of pull; disposable syringe uses the back as hospital refuse; burn destruction, be unfavorable for protecting environment, also increased patient's financial burden.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the above problems, and a kind of easy and simple to handle, safety, environmental protection, economic formulation operations apparatus are provided.

This utility model double needle main body is made as two ends all with the needle body of pin hole, and outside, needle body stage casing is provided with hand-held needle handle.

As a kind of improvement of the present utility model, pin hole is made as the side opening at syringe needle place.

Use plastic bottle as medical liquid container at present clinically more and more, this utility model double needle with mould bottle liquid and be used, the bottle of moulding that liquid is housed is inserted in one scalp acupuncture hole, the other end pin hole inserts in the liquid or powder injection bottle that will extract, extruding is moulded bottle and is utilized and to mould a bottle profile and have transmutability, change the air pressure in the bottle, injectable powder liquid suction after liquid or the dissolving is moulded in the bottle, reach the suction purpose, like this, just the opportunities for contamination that does not exist the pull pintle to cause is avoided the generation of infusion reaction, only need to prick on the bottle stopper pin hole during operation and need repeatedly to prick the hole before just can finishing, repeatedly aspirate the work that just can finish, it is time saving and energy saving to operate, and the time spent shortens more than 50%, and keeping liquid full dose (glucose 400ml+ normal saline 100ml) with preparation is example, when originally using the 20ml syringe, the suction number of times be 20 times, 240 seconds times spent, use this utility model instead after, the suction number of times only is 2 times, 100 seconds times spent.To dissolve 1 penicillin is example, and the suction number of times was 4 times when using the 20ml syringe originally, 40 seconds times spent, after adopting this utility model, the suction number of times only is 2 times, and is 20 seconds times spent, not only easy and simple to handle, and owing to saved syringe, the pintle of syringe, reduced the waste of resource, syringe needle not with contact patients, can carry out recycling, there is not the problem of burning hospital refuse, helps environmental protection.If each patient used two 20ml syringes every day at least in the past, every market unit price is 0.8 yuan, can save more than 1 yuan behind the use double needle, has alleviated patient's financial burden.In addition, pin hole is made as the side opening at syringe needle place, and when having avoided pricking the hole on bottle stopper, crumb of bottle stopper stops up pin hole.

Description of drawings

Fig. 1 is this utility model structural representation.

The specific embodiment

As shown in Figure 1, this utility model double needle main body is the needle body 1 that two ends all have pin hole 2, and the outside, stage casing of needle body 1 is with hand-held needle handle 3, and needle handle 3 can be flat or circle, the surface can have the tiny striped 4 that increases hand-held frictional force, about needle handle 3 length 3cm, refer to that with thumb, forefinger, middle finger three holding pin is advisable, about needle body 1 length overall 8cm, length will suit, long then syringe needle stretches in the bottle too much, is not easy to liquid in the bottle is all extracted out, too shortly then is not easy to prick bottle stopper.In addition, pin hole 2 is opened the side opening of promptly making needle body in the side of syringe needle place needle body 1, rather than the apical pore of common syringe needle, and when having avoided pricking the hole on bottle stopper, crumb of bottle stopper stops up pin hole 2.Needle body 1 adopts draw point, and needle handle 3 can adopt medical plastic to make.

When obtaining liq uses, insert the two ends of double needle in the liquid bottles respectively, be added into the bottle infra of liquid, a bottle liquid is moulded in the extruding upper end, makes it to enter in the following bottle, reach and unclamp when a certain amount of, make on the air admission in the bottle of lower end in the bottle, bottle is gone up in extruding once more, and down bottle injects liquid, repeatedly repeat aforesaid operations, shut-down operation when determining that according to the scale on the upper and lower bottle amount of liquid that injects extremely is fit to.

During the dissolving injectable powder, the end insertion of double needle is moulded in bottle liquid, the other end inserts in the powder injection bottle, mould bottle last, push the bottle of moulding of top, appropriate amount of fluid is injected in the powder injection bottle of below, after treating medicine dissolution, bottle is moulded in extruding once more, liquid is aspirated back to mould in the bottle get final product.

Claims (2)

1, a kind of double needle is characterized in that: its main body is made as two ends all with the needle body (1) of pin hole (2), and needle body (1) outside, stage casing is provided with hand-held needle handle (3).
