Abstract
The utility model provides a kind of molten medicine needle, including draw point and dual-purpose needle stand, it is characterised in that：Feed pathway and inlet channel are equipped in the dual-purpose needle stand, described feed pathway one end is connected with draw point, the other end of feed pathway is equipped with and the matched connector of syringe, inlet channel both ends are respectively equipped with air admission hole and venthole, the air admission hole is located at the base portion of dual-purpose needle stand, and venthole is located at the top of dual-purpose needle stand.The beneficial effects of the utility model be due to the adoption of the above technical scheme, molten medicine needle it is more convenient to use；Have many advantages, such as simple in structure, processing cost is low, production efficiency is high.
Description
Technical field
The utility model is related to a kind of medication injections equipment, more particularly, to a kind of molten medicine needle.
Background technology
Syringe needle is the hollow metal needle that syringe head end can be loaded and unloaded freely, may require that sometimes in medical method and uses spy
Different molten medicine syringe needle carries out drug to be administered to patient again after mixing in proportion, can effectively mix drug in proportion in this way
It closes, is conducive to medical treatment.Existing molten medicine needle, because being all closed after medicine bottle powder charge, is using process mostly without venthole
In, it needs to insert an exhaust pipe on medicine bottle, drug can be pumped out, this method is needed during application to medicine bottle
Rubber stopper punctured repeatedly, it is easily that liquid or micronic dust band is into the liquid, cause the pollution of liquid, influence health.
202270167 U of patent CN disclose a kind of Disposable air-filtering type medicine dissolving needle, and there is provided air inlets simultaneously on syringe needle
Channel reduces the puncture action for being inserted into the operation such as exhaust pipe to medicine bottle bottle closure of rubber, reduces the possibility of liquid medicine contamination.
Utility model content
The purpose of this utility model is to provide a kind of molten medicine needle with inlet channel, and simple in structure, of low cost.
The technical solution of the utility model is：A kind of molten medicine needle including draw point and dual-purpose needle stand, is set in the dual-purpose needle stand
There are feed pathway and inlet channel, described feed pathway one end is connected with draw point, and the other end of feed pathway is equipped with and syringe
Matched connector, inlet channel both ends are respectively equipped with air admission hole and venthole, and the air admission hole is located at the base portion of dual-purpose needle stand,
Venthole is located at the top of dual-purpose needle stand.Inlet channel avoids the action for being inserted into exhaust pipe, meanwhile, inlet channel is located at ABS
On the needle stand of material, the making of needle stand uses Shooting Technique, compares the design being located at inlet channel on draw point, can be effectively simple
Metaplasia production. art, reduces cost.In addition, there are a certain distance between the inlet opening of draw point and the venthole of inlet channel,
Extract liquid during can make inlet opening and venthole respectively be located at medicine bottle Chinese medicine liquid liquid level both sides up and down, venthole to
The air entered in medicine bottle is directly entered the air part in medicine bottle, and the contact area with liquid is the area of liquid level in medicine bottle,
It is located at the design at draw point needle point compared to venthole, the air that venthole enters into medicine bottle will not be in liquid with bubble shape
Formula rises, and reduces the contact area of air and liquid, is further reduced the possibility of liquid medicine contamination.
The top of the dual-purpose needle stand is pyramidal structure, and the venthole is located on the prism of pyramidal structure, used
It needs to be inserted into the bottle closure of rubber of medicine bottle at the top of needle stand in journey, pyramidal structure is more advantageous to the insertion of needle stand.
The dual-purpose hub outer surface is additionally provided with the ribs along dual-purpose needle stand axis direction, one end position of the ribs
Below air admission hole, the other end of ribs extends to dual-purpose needle stand base portion；The ribs at the top of dual-purpose needle stand one
It is 1 to hold the distance of air admission hole and ribs length ratio:3-1:5.In order to facilitate puncture, dual-purpose needle stand top design obtains relatively
It is relatively thin, though the needle stand intensity of ABS materials is enough to penetrate the bottle closure of rubber of medicine bottle, still not as good as the hardness of draw point height, ribs
On the basis of design passes through rubber stopper function at the top of dual-purpose needle stand, reduce the length of narrower portion at the top of dual-purpose needle stand, have
The risk being broken off at the top of dual-purpose needle stand is reduced to effect, meanwhile, ribs is carried out for being inserted into the depth of medicine bottle at the top of needle stand
Limitation prevents venthole caused by excessive insertion to be located at below liquid face.
The internal diameter of the feed pathway and inlet channel ratio is 2:1-3:1, the resistance of air in the duct is relative to liquid
Smaller, the internal diameter for reducing inlet channel advantageously reduces diameter at the top of dual-purpose needle stand, under the premise of air inlet function is ensured, more
Facilitate and rubber stopper is inserted at the top of needle stand.
The utility model has the advantages and positive effects of：Due to the adoption of the above technical scheme, the use of molten medicine needle is more
Add conveniently；Have many advantages, such as simple in structure, processing cost is low, production efficiency is high.

Specific embodiment
As shown in Figure 1, a kind of molten medicine needle of the utility model, including draw point 1 and dual-purpose needle stand 2, sets in the dual-purpose needle stand 2
There are feed pathway 11 and inlet channel 21, described 11 one end of feed pathway is connected with draw point 1, and the other end of feed pathway 11 is equipped with
With the matched connector of syringe, 21 both ends of inlet channel are respectively equipped with air admission hole 212 and venthole 211, the air admission hole 212
Positioned at the base portion of dual-purpose needle stand 2, venthole 211 is located at the top of dual-purpose needle stand 2.
The top of the dual-purpose needle stand 2 is pyramidal structure, and the venthole 211 is located on the prism of pyramidal structure.
