Abstract
It can prevent the dispensing injector with pin of medical fluid splash, including syringe, syringe needle and piston；The inner cavity for accommodating medical fluid is equipped in syringe, syringe one end is equipped with piston installing port, and the other end is equipped with pintle, and syringe needle is connected on the pintle of syringe, and piston is movably arranged at the piston installing port of syringe；Syringe outer wall is equipped with the fin extended along its axial direction；It further includes protection tube, and protection tube inner wall is equipped with the sliding slot extended along its axial direction；Protection tube loop is on syringe outer wall, the sliding slot of inner wall and the fin slide fit of syringe outer wall.The utility model has the advantage of the pintle of syringe needle and syringe is integrally formed, and the two separation during pushing away medicine is effectively prevent to cause liquid leakage；Protection tube loop effectively blocks the medical fluid splash during molten medicine, prevents medical fluid from splashing nurse's arm, facial area on syringe outer wall.
Description
Technical field
The utility model relates to medical instrument, especially a kind of dispensing injector with pin that can prevent medical fluid splash.
Background technique
The structure of existing syringe is as shown in figure 3, include syringe 1, syringe needle 2 and piston 3；It is equipped in syringe 1 and accommodates medicine
The inner cavity of liquid, 1 one end of syringe are equipped with piston installing port, and the other end is equipped with pintle 11, and syringe needle 2 is removably sleeved on syringe 1
On pintle 11, piston 3 is movably arranged at the piston installing port of syringe 1, and part of it protrudes into 1 inner cavity of syringe, and can be along
1 inner wall of syringe moves back and forth, to reduce or expand the volume of 1 inner cavity of syringe.
But existing syringe not suitable configuration chemotherapeutics, is primarily present following shortcoming:
1, syringe needle and pintle be using dismountable connection, if using when to push away medicine too fast, cause syringe chamber pressure to increase suddenly
Add it is excessive, syringe needle be easy from pintle deviate from, cause chemotherapeutics to leak out, be stained on the skin of medical staff, damage skin
Skin tissue；
2, during molten medicine, since the pressure in the bottle is big, chemotherapeutics is easy the splash from puncturing hole and comes out, and splashes nurse
Arm, facial area, harm are serious.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a kind of note that makes up a prescription that can prevent medical fluid splash
Emitter, it solve existing syringe during pushing away medicine syringe needle be easy at pintle abjection, molten medicine process Chinese medicine liquid easily from
The problem of puncturing hole sprays.
The technical solution of the utility model is: can prevent the dispensing injector with pin of medical fluid splash, including syringe, syringe needle and work
Plug；The inner cavity for accommodating medical fluid is equipped in syringe, syringe one end is equipped with piston installing port, and the other end is equipped with pintle, and syringe needle is connected to
On the pintle of syringe, piston is movably arranged at the piston installing port of syringe, and part of it protrudes into syringe inner cavity, and can be along
Syringe inner wall moves back and forth, to reduce or expand the volume of syringe inner cavity；
Syringe outer wall is equipped with the fin extended along its axial direction；It further includes protection tube, on protection tube inner wall
Equipped with the sliding slot extended along its axial direction；Protection tube loop is on syringe outer wall, sliding slot and the syringe outer wall of inner wall
Fin slide fit.
The further technical solution of the utility model is: syringe needle is fixed on the pintle of syringe.
Further technical solution is the utility model: the pintle of syringe needle and syringe is integrally formed.
The further technical solution of the utility model is: one end enlarged-diameter of protection tube towards syringe needle is in horn mouth
Shape.
The further technical solution of the utility model is: it further includes protective case of the loop in needle tip.
The utility model has the advantages that compared with prior art
1, the pintle of syringe needle and syringe is integrally formed, and the two separation during pushing away medicine is effectively prevent to cause liquid leakage.
2, protection tube loop effectively blocks the medical fluid splash during molten medicine, prevents medical fluid from splashing on syringe outer wall
Nurse's arm, facial area.
The utility model is further described below in conjunction with figure and embodiment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is the structural schematic diagram of existing syringe.
Specific embodiment
Embodiment 1:
As shown in Figs. 1-2, the dispensing injector with pin of medical fluid splash, including syringe 1, syringe needle 2, piston 3 and protective jacket can be prevented
Pipe 4.
The inner cavity for accommodating medical fluid is equipped in syringe 1,1 one end of syringe is equipped with piston installing port, and the other end is equipped with pintle 11, needle
1 outer wall of cylinder is equipped with the fin 12 extended along its axial direction.
Syringe needle 2 is connected on pintle 11, and is integrally formed with pintle 11.
Piston 3 is movably arranged at the piston installing port of syringe 1, and part of it protrudes into 1 inner cavity of syringe, and can be along needle
1 inner wall of cylinder moves back and forth, to reduce or expand the volume of 1 inner cavity of syringe.
4 inner wall of protection tube is equipped with the sliding slot 41 extended along its axial direction, and 4 loop of protection tube is in 1 outer wall of syringe
On, the sliding slot 41 of inner wall and 12 slide fit of fin of 1 outer wall of syringe.
It is preferred that one end enlarged-diameter of protection tube 4 towards syringe needle 1 is in toroidal, protection tube 4 covers when convenient for making up a prescription
The firmly head of entire dispensing bottle.
It is preferred that further include protective case 5 of the loop in 1 tip of syringe needle, with syringe needle is inserted on protective case 5 after complete medicine, then
Row storage can avoid residue medical fluid and be volatized into air.
