Description
Technical field
This utility model relates to a kind of blood taking needle.
Background technology
The blood taking needle generally used clinically can see Fig. 1; be made up of syringe needle, protective cap, needle handle, connection tube and blood sampling pipe close puncturing head; first carry out venipuncture with blood taking needle during blood sampling, then with infusion patch, needle handle is fixed on body surface, then blood sampling pipe close puncturing head insertion blood taking tube is taken a blood sample.But clinical practice finds, at some basic hospitals, blood sampling section office are due to blood sampling task weight, a lot of clinical nurse does not use infusion patch to fix needle handle when taking a blood sample, be easy to like this cause syringe needle to deviate from from Ink vessel transfusing, cause needs of patients secondary puncture, simultaneously syringe needle is deviate from and is also brought the potential safety hazard of stabbing to patient and nurse, adds the risk of infection.Clinical research finds in addition, after extracting blood taking needle, if return trocar cap again, be easy to cause pricking wound, therefore a lot of hospital does not allow back trocar cap, but this causes again used syringe needle outside exposed, have when processing the used blood taking needle as medical waste the potential safety hazard causing pricking wound.
Summary of the invention
In order to solve the awkward technical problem of current blood taking needle, this utility model provides one can pack up syringe needle safely, is convenient to the blood taking needle of fixing blood sampling simultaneously.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is, a kind of blood taking needle, comprise syringe needle, needle handle, connection tube and blood sampling pipe close puncturing head, one end of described needle handle is connected with blood sampling pipe close puncturing head by connection tube, the other end is fixed with syringe needle, it is characterized in that, also comprise protective cap, the two ends of protective cap have for the syringe needle hole of extended needle and the connection pore for stretching out connection tube, syringe needle and needle handle are all set in protective cap, protective cap has a groove in axial direction extended, by extending out in groove, protective cap is outer also can slide along groove the handle of needle handle, the two ends of groove have one and are communicated with and the parallel holddown groove for fixed handle with groove, spring is provided with in described protective cap, described spring housing is contained on syringe needle, one end of spring is stuck in the junction of needle handle and syringe needle, the other end is stuck in protective cap.
Described a kind of blood taking needle; also comprise the fixing subsides for fixing blood taking needle; described fixing subsides comprise two linkage sections and are located at two canned paragraphs of linkage section side respectively; two described linkage sections are separately fixed on needle handle; the side of described canned paragraph is the sticking veneer being provided with viscose, and sticking veneer is provided with the protective layer for the protection of sticking veneer being convenient to tear.
Described a kind of blood taking needle, described holddown groove also has draw-in groove along spring-relaxation direction, and described draw-in groove is not communicated with groove, and the width of draw-in groove is not less than the handle width of needle handle, and length is not more than the handle length of needle handle.
Technique effect of the present utility model is, eliminates in blood collection procedure and needs to use infusion patch to paste fixing needle handle in addition, and easy to use, prevent the generation of secondary puncture as much as possible, specification operating process, simultaneously with Multifunctional protective helmet protection syringe needle, prevents the generation of pricking wound; This utility model has larger use value clinical, and clinic is promoted.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Wherein, 1 be syringe needle, 2 be needle handle, 3 be connection tube, 4 be protective cap, 6 be groove, 7 be holddown groove, 8 be spring, 9 be linkage section, 10 be canned paragraph, 11 be draw-in groove for blood sampling pipe close puncturing head, 5.
Detailed description of the invention
See Fig. 2, Fig. 3, Fig. 4, this utility model comprises syringe needle, needle handle, connection tube, blood sampling pipe close puncturing head and protective cap, one end of needle handle is connected with blood sampling pipe close puncturing head by connection tube, the other end is fixed with syringe needle, the two ends of protective cap have for the syringe needle hole of extended needle and the connection pore for stretching out connection tube, syringe needle and needle handle are all set in protective cap, protective cap has a groove in axial direction extended, by extending out in groove, protective cap is outer also can slide along groove the handle of needle handle, the two ends of groove have one and are communicated with and the parallel holddown groove for fixed handle with groove, spring is provided with in protective cap, spring housing is contained on syringe needle, one end of spring is stuck in the junction of needle handle and syringe needle, the other end is stuck in protective cap.Like this when storing, spring, to jack-up syringe needle in protective cap, allows syringe needle be fixed in protective cap and is unlikely to stretch out, and is fixed the handle of needle handle interior by holddown groove, prevents syringe needle from moving.When taking a blood sample, after syringe needle is stretched out protective cap, be stuck in by handle in the holddown groove of protective cap front end, when preventing from taking a blood sample, syringe needle bounces back in protective cap.
For the ease of being fixed syringe needle when taking a blood sample; this utility model also comprises the fixing subsides for fixing blood taking needle; described fixing subsides comprise two linkage sections and are located at two canned paragraphs of linkage section side respectively; two described linkage sections are separately fixed on needle handle; the side of described canned paragraph is the sticking veneer being provided with viscose, and sticking veneer is provided with the protective layer for the protection of sticking veneer being convenient to tear.After in syringe needle insertosome, fixing subsides are pasted onto body surface and prevent syringe needle from dropping by protective layer of tearing.Blood sampling patch mid portion and needle handle are connected as a single entity, and two ends respectively stretch out about 2-3cm, and viscose is medical viscose, and protective layer is tearable pad pasting.This fixing subsides makes the conventional infusion patch material used of material employing hospital.
In order to further fixed needle, holddown groove also has draw-in groove along spring-relaxation direction, and draw-in groove is not communicated with groove, and the width of draw-in groove is not less than the handle width of needle handle, length is not more than the handle length of needle handle, can effectively prevent syringe needle from moving in holddown groove and skidding off holddown groove like this.
During concrete use; first the handle of needle handle is stirred; handle is made to skid off in groove from holddown groove; then by handle, syringe needle is released outside protective cap, swing handle, make handle snap in the holddown groove of protective cap front end; just can stablize syringe needle not to be retracted in protective cap; then syringe needle is penetrated Ink vessel transfusing, fixing subsides are attached to body surface by the protective layer fixedly sticked of tearing.After blood sampling, fixing subsides of tearing, rotates handle, makes needle retractable in protective cap, finally got back to by handle card in the draw-in groove in holddown groove, can recycle.
