Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of anti-quick dispensing needle of exfoliation.
Background technique
It is air-tight bottle packaging that injection, which has half, in clinical application, and nurse is in suction solvent injection air-tight bottle dissolution drug and takes out
It during inhaling medical fluid configuration, often has a small amount of crumb of bottle stopper and drops in medical fluid, such as discovery is easily caused to patient not in time
Injury.Particulate matter enters human body through vein, and harmfulness is serious and lasting, including to the heart, lung, liver and kidney and blood vessel
Damage, even if having in infusion apparatus filter device to can avoid particle at present enters human body, but the particle that is visible to the naked eye hangs in the solution
It is floating, patient can be caused panic and the query to nursing quality.
The pin hole of traditional needle for dispensing medicine is provided with tip, and pin hole is inclined-plane, and syringe needle is easy when passing through seal of medicine bottle rubber stopper
Bottle stopper is cut, rubber scraps is easily caused to fall off.
There is improved needle for dispensing medicine later, the needle for dispensing medicine as disclosed in chinese patent library (application number:
201220003920.5, Authorization Notice No.: 202490232 U of CN), including needle body and needle stand, the needle body is with closed point
Pin hole is arranged in needle body side in end.The needle body tip is the conical structure of sealing, the extruding that such tip can be very well
Enter rubber stopper, rubber will not enter pin hole, effectively avoid or reduce the generation of scrap gum, so that it is guaranteed that the safety of injection.But its
Disadvantage is also apparent from: firstly, easily increase the contaminated chance of needle tubing exposure when piercing through bottle closure of rubber, and inconvenient for operation,
It wastes time, because pin hole is arranged in needle body side, when medical fluid is reduced to needle point or less, in order to aspirate clean medical fluid, operation
Personnel need the withdraw of the needle outward, take out when moving back；Secondly, when aspirating the medical fluid in ampoule bottle, suction is not clean, because pin hole is in needle
The setting of body side, does not reach the bottom of bottle of ampoule bottle, so causing the waste of medical fluid.
Summary of the invention
In order to solve the above problems existing in the present technology, the utility model provides a kind of quick dispensing needle of anti-exfoliation,
It, which is provided simultaneously in puncture process, to cut the rubber in rubber stopper, the avoidable needle tubing exposure of aspiration medicinal liquid is contaminated,
Easy to operate, reduction four advantages of liquid waste.
The utility model is solved the problems, such as by following technical proposals: a kind of anti-quick dispensing needle of exfoliation, including needle
Seat and needle tubing, needle tubing include needle tip and shank portion, it is characterised in that: an arc is curved between needle tip and shank portion pipe axis
Turning, keeps the pin hole of needle tip parallel with shank portion pipe axis or at an angle.
Specifically, the pin hole of needle tip and shank portion pipe axis institute's angle degree are not more than 30 °.
Specifically, the effective length exposed after the needle tubing insertion needle stand is no more than 18mm.
The positive beneficial effect of the utility model:
Firstly, making the pin hole and needle of needle tip by the way that a curved corners will be curved between needle tip and shank portion pipe axis
Bar portion pipe axis (is not more than 30 °) in parallel or at an angle, so that pin hole becomes " side opening ".Pass through setting for curved corners
It sets, the exfoliation of puncture process generation on the one hand can be reduced when piercing through bottle closure of rubber；On the other hand, when the medicine in suction ampoule bottle
When liquid, pin hole can directly contact the side bottom of ampoule bottle, may be implemented disposably to aspirate clean medical fluid, reduce liquid waste.
Secondly, the effective length exposed after needle tubing insertion needle stand is no more than 18mm, effective length of the utility model needle tubing
Degree be arranged according to the thickness of bottle closure of rubber, it is smaller than traditional needle tubing effective length, when piercing through bottle closure of rubber aspiration medicinal liquid because
Needle tubing effective length is small can to aspirate medical fluid completely without the withdraw of the needle, eliminate the process aspirated in the withdraw of the needle, therefore reduce
The effective length that exposes after needle tubing insertion needle stand, not only can it is contaminated and easy to operate to avoid needle tubing exposure, when saving
Between.

Specific embodiment
With reference to the accompanying drawing, the utility model is described further, but be not therefore limited in the utility model
Among the embodiment described range.
Embodiment 1
As shown in Figure 1, a kind of anti-quick dispensing needle of exfoliation that the present embodiment 1 is related to, including needle stand 1 and needle tubing 2, needle tubing 2
Including needle tip 22 and shank portion 21, it is characterised in that: a curved corners are curved between 21 pipe axis of needle tip 22 and shank portion,
Keep the pin hole 221 of needle tip 22 parallel with 21 pipe axis of shank portion.
Specifically, the needle tubing 2 is inserted into the effective length exposed after needle stand 1 no more than 18mm.
The positive beneficial effect of the present embodiment 1:
Firstly, making the needle of needle tip 22 by the way that a curved corners will be curved between 21 pipe axis of needle tip 22 and shank portion
Hole 21 is parallel with 21 pipe axis of shank portion, so that pin hole 221 becomes " side opening ".By the setting of curved corners, on the one hand exist
The exfoliation of puncture process generation can be reduced when piercing through bottle closure of rubber；On the other hand, when aspirating the medical fluid in ampoule bottle, pin hole
221 can directly contact the side bottom of ampoule bottle, may be implemented disposably to aspirate clean medical fluid, reduce liquid waste.
