Description
Technical field
This utility model relates to technical field of medical equipment, is specifically related to disposable safe blood taking needle.
Background technology
At present, medical institutions are generally direct blood taking needle blood sampling when conventional blood collection, though this method energy one people one pin, not by cross infection, patient directly sees syringe needle, produces the feared state of mind (particularly child).During another kind of blood sampling, get blood taking needle by blood collecting pen with the use of, blood taking needle is loaded in blood collecting pen, takes off blood taking needle after launching acupuncture, load onto another blood taking needle and reuse, because blood collecting pen reuses many times, as easy as rolling off a logly cause cross infection.Above two kinds of blood-sampling methods, medical and nursing work personnel directly contact blood taking needle, manually syringe needle dress is got when taking a blood sample, be easy to because of carelessness stab, cause cross infection, there is certain potential safety hazard, also have kind of a mode, blood taking needle more advanced at present, adopt retracting type, after blood sampling, needle automatic retracting is in housing, but this blood taking needle exists following drawback: one, the syringe needle of blood taking needle is being deposited in process, contacts for a long time with air, easy-to-rust, although there is block, block is poorly sealed close with syringe needle, is unfavorable for long storage periods; Two, the housing main body of existing blood taking needle is rounded, is unfavorable for the gripping of medical personnel, thus affects the accuracy of the blood sampling of blood taking needle.
Summary of the invention
The technical problems to be solved in the utility model is to provide disposable safe blood taking needle, it is poorly sealed close with syringe needle that this utility model not only efficiently solves traditional blood taking needle block, the problem of syringe needle easy-to-rust, infection, and it is rounded to efficiently solve traditional blood taking needle housing main body, affect the blood sampling degree of accuracy of medical worker.
This utility model is achieved through the following technical solutions:
Disposable safe blood taking needle, comprise shell body (1), shell body (1) one side is provided with bonnet (2), relative side is provided with protecgulum (3), described bonnet (2) is fixedly connected with pin holder (5) by spring (4), hollow blood collection needles protecting tube (8) is provided with inside described protecgulum (3) center, blood collection needles (6) is provided with in pin holder (5), sliding sleeve (7) is also provided with in shell body (1), one end that sliding sleeve (7) one end and pin holder (5) are provided with blood collection needles (6) is compressed contact and is connected, it is characterized in that: the stiff end (51) that pin holder (5) is provided with blood collection needles (6) side is the frustum of a cone, frustum of a cone maximum gauge is greater than hollow blood collection needles protecting tube (8) diameter.
The further Technological improvement plan of this utility model is:
The shape of cross section of described shell body (1) is square, and the shape of cross section of protecgulum (3) is circular, and link (11) and protecgulum (3) mating shapes of shell body (1) and protecgulum (3) are circular.
This utility model further Technological improvement plan is:
Described sliding sleeve (7) free end exposure is provided with protecgulum (3) side in shell body (1).
This utility model further Technological improvement plan is:
Described sliding sleeve (7) is slidably connected by symmetrically arranged slide rail on shell body (1) inwall and shell body (1).
This utility model compared with prior art, has obvious advantage:
One, this utility model is in use blood taking needle process; blood collection needles is compressed in housing; by the compression of sliding sleeve; blood collection needles can be launched by Compress Spring; the stiff end that pin holder is provided with blood collection needles side is the frustum of a cone; under stored condition; the frustum of a cone of pin holder inserts and is provided with in hollow blood collection needles protecting tube inside protecgulum center; blood collection needles is in closed environment; not easily corrosion; can also effectively avoid, the air outside needle contact, avoid further blood taking needle with transporting, deposit the probability that pathogenic bacteria in process contacts
Two, shell body main body portion of the handle shape of cross section of the present utility model is square, is more conducive to the gripping of medical worker, improves the accuracy of medical worker's blood sampling.
