Abstract

The present invention relates to a kind of disposable blood taking needle, it is suitable for examining blood sampling, is particularly suitable for the inspection project of the accurate blood sampling volume of the palpus such as blood clotting, erythrocyte sedimentation rate.The present invention provides a kind of disposable controller formula blood taking needle, and blood taking needle design is simple, safe ready, can accurately control blood sampling volume, can effectively prevent the cross-contamination issue in blood sampling.Disposable controller formula blood taking needle by blood sampling needle guard (1), blood collection needles (2), hold needle handle (3), needle tubing (4), controller (5), puncture needle handle (6), puncture needle (7), Puncture needle sleeve (8) form.

Description

Disposable controller formula blood taking needle
Technical field
The present invention relates to a kind of disposable blood taking needle, it is suitable for examining blood sampling, being particularly suitable for Blood coagulation test, erythrocyte sedimentation rate etc. must essence The inspection project of true blood sampling volume.
Background technique
The blood taking needle clinically used at present has the following problems: 1. cannot accurately control blood sampling volume；2. being extracted after blood sampling Puncture needle, drop of blood easily leak out, and not can effectively prevent cross contamination.
Summary of the invention
In order to effectively solve the above problems, the present invention provides a kind of disposable blood taking needle, is suitable for examining blood sampling, especially suitable Close the inspection project of the accurate blood sampling volume of the palpus such as Blood coagulation test, erythrocyte sedimentation rate.
The present invention solves technical solution used by phase technical problem: disposable controller formula blood taking needle is by blood sampling needle guard (1), blood collection needles (2), hold needle handle (3), needle tubing (4), controller (5), puncture needle handle (6), puncture needle (7), Puncture needle sleeve (8) Composition, it is characterized in that: controller (5) is connected to a fixed with needle handle (6) are punctured, needle tubing passes through controller bottom end, disposable to control The controller of device formula blood taking needle is characterized in: being made of shell (9), idler wheel (10), has sliding slot (12) in shell (9), for rolling Wheel is fixed, and shell is equipped with needle tubing import (13), barrel outlet (14), and idler wheel (10) both sides have roller shaft (11).Roller shaft (11) fixed with shell sliding slot (12) phase build-in.
The beneficial effects of the present invention are: blood taking needle design is simple, safe ready can accurately control blood sampling volume, can be effective The leakage of puncture needle drop of blood is extracted after solving the problems, such as blood sampling.It takes a blood sample suitable for examining, being particularly suitable for Blood coagulation test, erythrocyte sedimentation rate etc. must essence The inspection project of true blood sampling volume.
Detailed description of the invention
Fig. 1 is disposable controller formula blood taking needle figure
Fig. 2 is controller sectional view
1. blood sampling needle guard in figure, 2. blood collection needles, 3. hold needle handle, and 4. needle tubings, 5. controllers, 6. puncture needle handle, and 7. puncture Needle, 8. Puncture needle sleeves, 9. shells, 10. idler wheels, 11. roller shafts, 12. sliding slots, 13. needle tubing imports, 14. barrel outlets.
Specific embodiment
Person of blood collecting's skin is sterilized when use, removes blood sampling needle guard, checks that controller idler wheel, syringe needle are pierced into person of blood collecting's blood Pipe, after seeing blood back, removes Puncture needle sleeve, puncture is needled into heparin tube, holds heparin tube, and thumb is slowly pushed away to puncture needle direction Dynamic idler wheel can control blood sampling volume, until closing out blood flow, then successively extracts puncture needle and blood collection needles, is pushed down at needle thorn with cotton swab ?.
