Description
Technical field
This utility model relates to technical field of medical instrument, particularly a kind of Simple blood taking needle.
Background technology
At present, clinically when carrying out blood specimen collection to patient, most handheld syringe puncture vessel aspirates blood samples, owing to injector surface is smooth, it is easy to slip, thus causing puncture failure, add great work difficulty to medical worker, also add misery for patient. It addition, when pulling out pin, be generally adopted hemostasis cotton swab and directly bear against above extracting, when extracting, blood taking needle easily slides or the hands of user unintentionally encounters blood taking needle and causes injured, there is blood-borne patient for some, this not only makes patient painful, returns medical personnel and brings hidden danger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Simple blood taking needle, it is possible to while making blood sampling convenient, alleviate the misery of patient, it is to avoid the hidden danger existed in medical personnel's blood collection procedure.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of Simple blood taking needle, including syringe needle, needle tubing, piston and nook closing member, needle tubing side is provided with elastic bag, elastic bag is provided with sucker, elastic bag front end is provided with to help pulls out sliding sleeve, helps and pulls out sliding sleeve front lower surface and be provided with symmetrical inclined plane, and inclined plane lower end is provided with the notch adapted with syringe needle.
The described material pulling out sliding sleeve that helps is silicone rubber.
Described elastic bag surface is with detent projection.
This utility model one Simple blood taking needle, by arranging the elastic bag with sucker, can realize blood taking needle location by sucker on the one hand, make blood sampling stable, can prevent from breakking away by elastic bag on the other hand, stable when making blood taking needle inject, accurate without error, reduce the misery of patient; Syringe needle can be positioned after blood taking needle is extracted by arranging to help to pull out to slide over, thoroughly be reduced the unexpected injury that syringe needle sideslip brings by second positioning, some are existed blood-borne patient, has thoroughly stopped hidden danger.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Fig. 2 helps the structural representation pulling out sliding sleeve in this utility model.
In figure: syringe needle 1, needle tubing 2, piston 3, nook closing member 4, elastic bag 5, sucker 6, help and pull out sliding sleeve 7, inclined plane 8, notch 9.
Detailed description of the invention
As shown in Figure 1 and 2, a kind of Simple blood taking needle, including syringe needle 1, needle tubing 2, piston 3 and nook closing member 4, needle tubing 2 side is provided with elastic bag 5, elastic bag 5 is provided with sucker 6, elastic bag 5 front end is provided with to help pulls out sliding sleeve 7, helps and pulls out sliding sleeve 7 front lower surface and be provided with symmetrical inclined plane 8, and inclined plane 8 lower end is provided with the notch 9 adapted with syringe needle.
The described material pulling out sliding sleeve 7 that helps is silicone rubber. Silicone rubber is more soft so, improves comfort level.
Described elastic bag 5 surface is with detent projection. Thus structure, can play anti-skidding purpose.
When carrying out blood specimen collection to patient, after syringe needle 1 punctures inserting needle, hands pinches elastic bag 5, is adsorbed on patient's local skin by sucker 6; When extracting syringe needle 1, take off from the fixed chuck of needle tubing 2, the notch 9 in inclined plane 8 is pressed in syringe needle 1 place, extracts.
