Description

A kind of blood taking needle

Technical field

This utility model relates to technical field of medical instrument, especially a kind of blood taking needle.

Background technology

In use there is great problems in blood taking needle: 1), clinically when carrying out blood specimen collection to patient, most handheld syringe puncture vessel aspirates blood samples, injector surface is smooth, easily slips；2), after injection completes, owing to part blood can produce backflow, easily antibacterial etc. is brought into into the human body, cause superinfection；3, either injection or recovery, needle point is likely to scathing finger, easily causes infection.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of blood taking needle, it is possible to solve above technical problem, and simple and practical property is strong.

For solving above-mentioned technical problem, this utility model be the technical scheme is that

A kind of blood taking needle, described needle tubing include front pipe and closely viscous with front tube side wall and rear pipe, be provided with rubber membrane between front and rear tube, on rubber membrane, circumference is equidistant has multiple hole, and hole holding connects with front and rear tube；Being provided with suction tube in described front pipe, suction tube contacts with rubber membrane central solid portion；Being cased with guard member on described rear pipe outer wall, including fixture and sliding part, chute slide anteroposterior on fixture is passed through at sliding part rear portion, and sliding part front end is provided with groove, and size adapts with syringe needle.

It is hinged with sucker on described rear pipe.

The fastener of mutually fastening it is respectively equipped with on described fixture and sliding part.

This utility model one blood taking needle, has following technical effect that

1), by arranging rubber membrane, make the liquid one-way flowing between front Guan Yuhou pipe, prevent the backflow of a small amount of liquid in a small amount of blood taking needle from causing infection.

2), by arranging guard member, when pulling out pin, can opponent's fingering row protection, may utilize when focusing on upon completion of the injection in guard member sliding part upset after with fixture snapping, so can wrap syringe needle, prevent collection from when processing, injuring hands.

3), by arranging hinged sucker, when can conveniently inject, hands applies power to the syringe of blood taking needle, prevents from slipping, hinged sucker then convenient location, and syringe needle can be made freely to move up and down, and improves motility.

Accompanying drawing explanation

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:

Fig. 1 is schematic diagram of the present utility model.

Fig. 2 is the sectional view of needle tubing junction in this utility model.

Fig. 3 is the schematic diagram of guard member in this utility model.

In figure: needle tubing 1, front pipe 2, rear pipe 3, rubber membrane 4, hole 5, suction tube 6, guard member 7, sucker 8, fixture 9, sliding part 10, chute 11, groove 12, syringe needle 13, fastener 14.

Detailed description of the invention

As Figure 1-3, a kind of blood taking needle, described needle tubing 1 include front pipe 2 and closely viscous with front pipe 2 sidewall and rear pipe 3, be provided with rubber membrane 4 between front pipe 2 and rear pipe 3, on rubber membrane 4, circumference is equidistant has multiple hole 5, and hole 5 keeps connecting with front pipe 2 and rear pipe 3；Being provided with suction tube 6 in described front pipe 2, suction tube 6 contacts with rubber membrane 4 central solid portion；It is cased with guard member 7 on described rear pipe 3 outer wall; being quality of rubber materials including fixture 9 and sliding part 10, fixture 9 and sliding part 10, chute 11 slide anteroposterior on fixture 9 is passed through at sliding part 10 rear portion; sliding part 10 front end is provided with groove 12, and size adapts with syringe needle 13.

It is hinged with sucker 8 on described rear pipe 3.Can realize fixing for needle tubing location by sucker, convenient operation.

The fastener 14 of mutually fastening it is respectively equipped with on described fixture 9 and sliding part 10.It is achieved in fixture 9 and sliding part 10 carries out buckle and closes up locking.

Operation principle and process:

1), blood back flow is prevented: during blood drawing, due to piston rod effect, blood enters in suction tube 6, back down rubber membrane 4 and enter front pipe 2, then pipe 3 after being entered into by hole 5, after stopping blood transfusion, rubber membrane 4 is under the effect of rear pipe 3 blood, it is in close contact with suction tube 6, thus effectively prevents blood back flow.

2), sharps injury is prevented: before work, pull open sliding part 10 to suitable length, after blood drawing terminates, pin syringe needle with sliding part 10 front end, syringe needle is extracted, so can reduce the unexpected injury to finger when pulling out pin, after taking out pin, pull on sliding part 10, after upset encases syringe needle, buckled by fastener 14.

3), anti-skidding: when carrying out blood specimen collection to patient, after syringe needle punctures inserting needle, hands pinches the elastic bag of sucker 8 upper end, is adsorbed on patient's local skin by sucker 8.
