Description
Technical field
The utility model is related to medical supplies, especially a kind of dispensing syringe with degassing function.
Background technology
Medical staff is often used syringe and the dispensing needle of big specification to allocate intravenous medicine at work.It is existing
Syringe usually not degassing function can cause the pressure in bottle gradually to increase when injecting liquid into powder bottle or mother liquid multi-cavity bottle
Greatly.
Pressure in bottle excessive will produce two kinds of phenomenons：1, when syringe is repeatedly inserted into bottle closure of rubber, liquid in bottle can be made
The outside splash of body generates leakage.2, the increase of liquid is injected into bottle with syringe, pressure increases, and pushes syringe piston
The resistance of bar also can gradually increase, and making up a prescription to medical staff makes troubles；It such as applies on automatic dispensing machine, the variation meeting of resistance
To automatic dispensing machine push away pull out piston rod stress generate damping action, influence injection and suction bottle in liquid precision.
Also, existing syringe needle tube and syringe concentricity are bad, in the bad control needle point in robot that makes up a prescription
Insertion position.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, and provide it is a kind of with degassing function match medicinal note
Emitter, it solves existing syringe when injecting liquid into powder bottle or mother liquid multi-cavity bottle, easily causes the outside splash of liquid,
And the problem of pushing the resistance of syringe piston rod gradually to increase.
The technical solution of the utility model is：Dispensing syringe with degassing function, including syringe, piston rod, needle
Seat and needle tubing；The inner cavity for accommodating liquid is equipped in syringe；Piston rod is movably arranged in the inner cavity of syringe, and push-and-pull piston rod is in turn
Change the size of syringe inner cavity；Medicine liquid channel is equipped in needle holder, needle holder is connected on syringe, in medicine liquid channel and needle
The inner cavity of cylinder is connected；Syringe needle one end is mounted in the medicine liquid channel of needle holder, and the other end is exposed junction；
It further includes ventilation casing；Sleeve upper end of ventilating is equipped with exhaust outlet, and lower end is equipped with air inlet, sleeve upper end set of ventilating
Fill and be fixed in needle holder, form the toroidal cavity that passes through of gas supply stream between inner wall and the outer wall of syringe needle, exhaust outlet and into
Gas port is connected to toroidal cavity respectively.
The further technical solution of the utility model is：The exhaust outlet is the bar shaped hollow out positioned at ventilation sleeve upper end
Hole, the air inlet are the arch notch positioned at ventilation lower end.
Further technical solution is the utility model：Ventilation casing is in the tapered taper type of outer diameter in lower end, under
Hold the internal diameter of end consistent with the outer diameter of syringe needle.
The further technical solution of the utility model is：Needle holder is integrally formed with syringe.
The utility model has the following advantages that compared with prior art：
1, there is degassing function, carry out can guarantee that bottle inner and outer air pressure is consistent when pushing away medicine operation.In use, syringe needle and ventilation set
Pipe end portion punctures bottle stopper and enters in bottle (powder bottle or mother liquid multi-cavity bottle), and ventilation sleeve upper end part is located at outside bottle, then carries out
Liquid is injected, and the air in powder bottle or mother liquid multi-cavity bottle enters toroidal cavity by the air inlet for casing of ventilating, then is covered by ventilating
The exhaust outlet of pipe exports to outside bottle, keeps bottle external and internal pressure identical.
2, needle holder and syringe are integrally formed, and syringe needle is fitted close with needle holder, and ventilation casing and needle holder are close
Cooperation, and then ensure that the concentricity requirement of needle tubing and syringe.
The utility model is further described below in conjunction with figure and embodiment.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the three-dimensional structure diagram of ventilation casing；
Fig. 3 is three-dimensional structure diagram of the casing under another visual angle of ventilating；
Fig. 4 is the sectional structure chart of the utility model.
Explanation：Upper end and piston rod omission are not drawn in Fig. 4.
Specific implementation mode
Embodiment 1：
As shown in Figs 1-4, the dispensing syringe with degassing function, including syringe 1, piston rod 2, needle stand 3, needle tubing 4
And ventilation casing 5.
The inner cavity 11 for accommodating liquid is equipped in syringe 1.
Piston rod 2 is movably arranged in the inner cavity 11 of syringe 1, push-and-pull piston rod 2 and then the size for changing 1 inner cavity of syringe.
Medicine liquid channel 31 is equipped in needle stand 3, needle stand 3 is connected on syringe 1, in medicine liquid channel 31 and syringe 1 it is interior
Chamber 11 is connected.
4 one end of needle tubing is adhesively fixed in the medicine liquid channel 31 of needle holder 3, and the other end is exposed junction.
5 upper end of casing ventilate equipped with exhaust outlet 51, lower end is equipped with air inlet 52, and the exhaust outlet 51 is positioned at ventilation casing
The bar shaped hollow hole of 5 upper ends, the air inlet 52 are the arch notch positioned at 5 lower end of ventilation casing.5 upper end of ventilation casing suit
And be adhesively fixed on needle stand 3, the toroidal cavity 6 that gas supply stream passes through, exhaust outlet 51 are formed between inner wall and the outer wall of needle tubing 4
It is connected to respectively with toroidal cavity 6 with air inlet 52.
It is preferred that ventilation casing 5 is in the tapered taper type of outer diameter, the outer diameter of the internal diameter and needle tubing 4 of lower end in lower end
Unanimously.The structure can guarantee that ventilation casing 5 blocks needle tubing 4 in lower end, plays the role of fixed needle tubing 4, prevents needle tubing 4 from deviating from.
Also, when needle tubing 4 punctures bottle closure of rubber and enters powder bottle or mother liquid multi-cavity bottle, 5 lower end of ventilation casing can be also convenient in taper type
