The specific embodiment
As seen from Figure 1, a kind of single-blade high-safety needle staying on vein of this utility model mainly includes and comprises puncture needle assembly, indwelling casing tube assembly, transfusion three way cock assembly etc.The puncture needle assembly comprises puncture needle 10, needle handle 11, needle handle fin.The indwelling casing tube assembly comprises three way type casing seat 3, sleeve pipe 2, sealing-plug 4 etc.Outside the above-mentioned sleeve pipe 2 helmet 1 is arranged, sleeve pipe 2 rear ends are connected with casing seat 3, casing seat 3 back segment inner chambers also are equipped with sealing-plug 4, puncture needle 10 was inserted sealing-plug 4 hermetically, it is through whole remaining needle sleeve pipe 2, casing seat 3 lateral branching pipes are connected with transfusion three way cock assembly by connecting leg 5, be that connecting leg 5 one ends are communicated with remaining needle sleeve pipe 2 by casing seat 3, the other end connects threeway 7, threeway 7 two outlets in addition has nipple and calparine cap 8 and end cap 9 to spin, and medicinal liquid enters threeway 7 by calparine cap 8, the connecting leg 5 of flowing through, prop up through casing seat 3 side direction and mouthful to enter the casing seat ante-chamber and flow to sleeve pipe 2, enter vein blood vessel at last.When carrying out two kinds of medicinal liquid transfusions,, connect other transfusion apparatus and get final product as long as screw off end cap.Clip 6 is housed on this utility model connecting leg 5, when the patient suspends transfusion because of needs, as long as clamp connecting leg 5 with clip 6, disconnects the connection between threeway 7 and the casing seat 3, the order transfusion takes time out to.Unclamp clip 6 when needing to recover transfusion and get final product, the operation simple and convenient.Above-mentioned composition structure is identical with prior art, no longer describes in detail.
It can also be seen that by Fig. 1 and Fig. 2 this utility model casing seat 3 rear portions are provided with needle handle cover 12 that connects needle handle 11 and the puncture needle safety shield assembly of being made up of intermediate connector 14 and sheath 15.Intermediate connector 14 front ends are plugged in casing seat 3 back end interfaces, and the rear end is connected with sheath 15 tight fits, and this safety shield 15 is tubular shells, and sheath 15 housings are axially arranged with needle handle slide-and-guide groove 15a.Gathering sill 15a extends to terminal buckle 15b from sheath 15 front end ends, and the length of sheath 15 and gathering sill is greater than the length of described puncture needle 10.Like this, can guarantee that puncture needle 10 can cover in the sheath 15 fully.Have an annular protrusion 14a to match with casing seat 3 rear end inner chamber annular grooves on this utility model intermediate connector 14 front end cylindricals, the two plugs together fixing.
This utility model puncture needle 10 tail ends are fixed on the needle handle 11, and it passes sealing-plug 4 and intermediate connector 14 and is inserted in the sleeve pipe 2.Fig. 3 is this utility model needle handle and needle handle nested structure sketch map.Cylindrical needle handle 11 links to each other by perpendicular muscle 11a with the needle handle cover 12 that is provided with single-blade fin 13, and needle handle cover 12 is fastened on sheath 15 outsides, and it can drive needle handle 11 and slide backward along sheath 15.Here, perpendicular muscle 11a is used for connecting needle handle 11 and needle handle cover 12 on the one hand, makes them into a single integrated structure, and it slides along gathering sill 15a on the other hand, its guide effect.
This utility model needle handle cover 12 its outsides are axially arranged with a notch 12a, and the edge level of notch 12a is provided with single-blade fin 13.Single-blade fin 13 is convenient to operator's puncture procedure.
The terminal shell face of this utility model sheath gathering sill 15a is provided with buckle 15b, and it is to be fastened by terminal two elastic card claws of processing of gathering sill 15a to form, and needle handle 11 is provided with draw-in groove 11b accordingly with the needle handle cover 12 perpendicular muscle 11a rear ends that link to each other.Like this, overlap 12 grades to gathering sill 15a when terminal when pulling back needle handle, the draw-in groove 11b on buckle 15b and the perpendicular muscle 11a cooperates, and buckle 15b blocks needle handle 11 and needle handle cover 12, makes the puncture needle 10 can't be to front slide.
After this utility model puncture is finished, when needle handle cover 12, when needle handle 11 is extracted backward together with puncture needle 10, the perpendicular muscle 11a of needle handle 11 is along sliding among the gathering sill 15a of sheath 15, when tip portion is extracted through sealing-plug 4, sealing-plug 4 can seal pin hole immediately, the buckle 15b of gathering sill 15a rear end blocks needle handle 11 and needle handle cover 12, makes the puncture needle 10 can't be to front slide.This moment, puncture needle 10 can be capped fully; continue then to exert oneself backward; the annular protrusion 14a of intermediate connector 14 is broken away from from casing seat 3 rear end annular grooves; extract whole puncture needle safety shield assembly and puncture needle assembly; so just stopped needle tubing and exposed the harm that is brought, protected effectively that medical personnel's is healthy.
