Abstract

The utility model relates to an infusion syringe with a powder dilution function, which is composed of an infusion seat, an infusion pipe, an air inlet hole and an air outlet hole. The utility model is characterized in that a breather pipe is coaxially sheathed on the infusion pipe and is fixedly connected to the infusion seat, and the air inlet hole and the air outlet hole are positioned on both ends of the breather pipe. The utility model has the advantages of simple structure, low production cost, convenient use, raised work efficiency, reduced labor intensity, avoidance of medicine pollution and reduced medical cost.

Description

Infusion syringe with powder dilution function

This utility model relates to a kind of medical apparatus and instruments, especially a kind of Dilution for powder fluid injection pin.

Antibiotic is the common drug in the clinical treatment, mostly is bottled powder, during use, and necessary dissolved dilution, current, use entry needle to press the traditional operation method mostly, dilute its complex operation step, inefficiency, labor intensity is big, and the medicine cost consumption is big, the expense height.CN87213807, CN88203073 disclose " air tight cycle drug dilution device " and " automatic drug air mix facilities " respectively, though using these devices can increase work efficiency, reduce labor intensity, reduce opportunities for contamination, but, their structure is all complicated, the cost height, and it is very not convenient to use.

The purpose of this utility model provides a kind of easy to use, high efficiency, and labor intensity is little, reduces opportunities for contamination, reduces medical treatment cost, and simple in structure, the Dilution for powder fluid injection pin of low production cost.

This utility model is made up of liquid injection seat, liquid injection pipe, breather, air inlet, venthole, and breather is enclosed within the liquid injection pipe outside and is fixed on the liquid injection seat, and air inlet, venthole are positioned at the two ends of breather.

This utility model is simple in structure, compact, production cost is low, and the dilution powder agent medicine is easy and simple to handle, high efficiency, and labor intensity is little, and has avoided the pollution to medicine, has reduced medical treatment cost.

Describe in detail below in conjunction with accompanying drawing:

Fig. 1 is this utility model structural representation;

Fig. 2 is embodiment 2 of the present utility model;

Fig. 3 is embodiment 3 of the present utility model.

Referring to Fig. 1, it also is a kind of most preferred embodiment of the present utility model, wherein, breather 3 is enclosed within the outside of liquid injection pipe 2, and with liquid injection pipe 2 coaxial being riveted on the liquid injection seat 1, on end of breather 3 and the liquid injection seat 1 that is connected, have to break-through venthole 5, the other end break-through of breather 3 have the gross thickness that air inlet 4, two pitchs of holes are slightly larger than bottled medicine aluminum skin and rubber stopper, penetrate the unimpeded of two holes, back to guarantee this breather, liquid injection seat 1 can select for use copper material to make, its taper hole is 6:100, and adopts the ISD594-85 international standard, to be applicable to the cooperation of all medical 6:100 coneheads, liquid injection pipe 2 and breather 3 can select for use stainless steel tube to make, liquid injection pipe 2 internal diameters are 0.8-1.4mm, and breather 3 internal diameters are 1.6-2.0mm, and the wall thickness of liquid injection pipe 2 and breather 3 is advisable with interior at 0.1mm.Around the venthole on the sidewall of liquid injection pipe 2 front ends and on the breather 34, also can have a plurality of holes.The characteristics of present embodiment can briefly be called " a two-tube coaxial riveted type Dilution for powder fluid injection pin ", during use, the injection of diluent and the discharge of air are very unobstructed, rapid, except that the material of making liquid injection pipe and needle tubing, do not need any other auxiliary material, excellent through clinical result of use.

Embodiment two:

As shown in Figure 2, liquid injection pipe 2 is riveted on an end of liquid injection seat 1, and breather 3 is riveted on an end of ventilation seat 6, and an end of breather 3 has air inlet 5, have to break-through venthole 4 on the other end and the ventilation seat 6 that is connected thereof, breather 3 is enclosed within liquid injection pipe 2 outsides and ventilation seat 6 and liquid injection seat 1 welding.The characteristics of present embodiment are summarised as " the two-tube welding type of two-seater ".

Embodiment three:

As shown in Figure 3, liquid injection pipe 2 is riveted on an end of liquid injection seat, on liquid injection pipe 2, welds breather 3 side by side, and an end of breather 3 has the venthole 5 that is the elbow shape, and the other end is an air inlet 4.Construction features of the present utility model can abbreviate " one two-tube parallel " as.

Claims

1, a kind of Dilution for powder fluid injection pin of being made up of liquid injection seat 1, liquid injection pipe 2, breather 3, air inlet 4, venthole 5 is characterized in that breather 3 is enclosed within liquid injection pipe 2 outsides and is fixedly connected on the liquid injection seat 1;

2, fluid injection pin according to claim 1, the internal diameter that it is characterized in that liquid injection pipe 2 is 0.8-1.4mm, and thickness of pipe wall is in 0.1mm, and the internal diameter of breather 3 is 1.6-2.0mm, and thickness of pipe wall is in 0.1mm.
