Description
Technical field
This utility model belongs to medical device technical field, especially relates to a kind of Medical solution preparation pin.
Background technology
In prior art, general dosing uses 2 needle points, and one is inserted into dosing soft bag bottleneck, and another one is syringe
First wife is also used for taking out the needle point of medicine, through first needle point above when of then medicine being thrown in bag, after having accomplished fluently
Separating with first needle point, continue to take out medicine with first wife's needle point and throw into, the first needle point is exposed smoking medicine when, and
Owing to soft bag cannot uprightly and the effect of pressure in bag, liquid can overflow from this needle point, trickles down treatment desktop, and traditional the
One needle point uses straight hole syringe needle, and when dosing, the rubber of Infusion bottle lid is easily stabbed and falls within preparation liquid by syringe needle straight hole, gives transfusion
The life security of patient constitutes certain danger.
Summary of the invention
This utility model purpose is: provide one to be not only simple in structure, easy to use, and during effectively preventing dosing
In bag, liquid leaks to treating desktop, prevents air atom from entering in bag simultaneously, reduces the Medical solution preparation pin of opportunities for contamination.
The technical solution of the utility model is: a kind of Medical solution preparation pin, including needle point body, after being located at described needle point body
The check-valves of end, and the syringe body being connected with described check-valves；Described check-valves includes and described needle point body rear end
The fixing valve body connected, and it is respectively arranged on inlet and the liquid outlet at described valve body two ends；At described valve inner and certainly enter
Liquid mouth to liquid outlet direction is sequentially provided with spool, sealing ring, sealing piston, valve core spring seat and stainless steel spring, described sealing
Snare is contained on described spool, and described sealing piston is fixed on described valve core spring seat, and described stainless steel spring is set in institute
State on valve core spring seat.
As preferred technical scheme, the front end of described needle point body is filled circles taper, and on this side of described needle point
Face is provided with at least one injection orifice.
As preferred technical scheme, described syringe body includes syringe body, and is located at described syringe tube
Internal piston and push rod.
As preferred technical scheme, described needle point body is one-body molded with described check-valves.
Operation principle of the present utility model is as follows: when syringe body pars papillaris is slightly firmly inserted from the inlet of check-valves
Enter, and the stainless steel spring on valve core spring seat is upwards bounced back be in compressive state, seal piston simultaneously and leave sealing ring, push away
The push rod of dynamic syringe body, liquid sequentially enters check-valves, needle point body, finally enters dosing bag；When dosing injection again
Time, separating syringe body and needle point body, stainless steel spring is upspring, and seals piston and seals sealing ring, effectively prevents dosing
In journey, in bag, liquid leaks to treating desktop, prevents air atom from entering in bag simultaneously, reduces opportunities for contamination.
The utility model has the advantages that:
1. this utility model is when dosing injection again, separates syringe body and needle point body, and stainless steel spring is upspring,
Seal piston and seal sealing ring, effectively prevent during dosing liquid in bag to leak to treating desktop, prevent air atom from entering simultaneously
Enter in bag, reduce opportunities for contamination；
2. the front end of this utility model needle point body is filled circles taper, and is provided with at least one at described this body side surface of needle point
Individual injection orifice, effectively prevents the rubber stopper granule foreign of transfusion bag from directly entering preparation liquid from needle point, reduces transfusion outpatient
Life danger.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:
Fig. 1 is this utility model structural representation；
Wherein: 1 needle point body, 2 valve bodies, 3 spools, 4 sealing pistons, 5 valve core spring seats, 6 stainless steel springs, 7 injection orifices,
8 syringe bodys, 9 pistons, 10 push rods, 11 sealing rings.
Detailed description of the invention
Embodiment: shown in reference Fig. 1, a kind of Medical solution preparation pin, including needle point body 1, it is located at stopping of needle point body 1 rear end
