Description
Technical field
This utility model relates to technical field of medical auxiliary equipment, is specifically related to a lock-fit-type 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 has kind of a mode, applicant's patent applied for, the patent No. is the disposable safe blood taking needle of 2013204399581, although solve the problems referred to above, but in actual use, because parts are more, in practical set process overall need twice sealed, assembly crewman slightly because of carelessness will this needle sting in assembling process, not only bring psychological shade to operating personnel, and the needle body of accidental launch needs to change, in case bring the hidden danger of cross infection.
Summary of the invention
The technical problems to be solved in the utility model is to provide a lock-fit-type safe blood-taking needle, and this utility model efficiently solves existing disposable blood taking needle, and parts are more, assembling process is complicated, needle body need twice sealed, not only efficiency of assembling is low, and operating personnel is easy to the problem of stabbing.
This utility model is achieved through the following technical solutions:
A lock-fit-type safe blood-taking needle, comprise housing (2), housing (2) one end is provided with pin cap (1), it is characterized in that: described housing (2) inside is provided with column storage pin chamber (6), housing (2) internal face between storage pin chamber (6) and housing (2) is provided with wedge-shaped slot (21), needle body (4) is provided with in storage pin chamber (6), needle body (4) is connected with spring (5) by needle body mount pad (7), and the hair device (3) of moving back that needle body mount pad (7) is arranged by housing (2) upper end is fixed on housing (2) inside.
The technical scheme that this utility model solves further is:
Described hair device (3) of moving back fixes clamping by the elastic card claw (34) of both sides with housing (2) inwall.
The technical scheme that this utility model solves further is:
Described hair device (3) bottom of moving back is connected with needle body mount pad (7), wedge-shaped slot (21) top respectively by claw (31,32).
The technical scheme that this utility model solves further is:
Described move back hair device (3) top center mutually in extendedly have needle body launch tube (33).
This utility model compared with prior art, has following obvious advantage:
One, this utility model parts are less, and primarily of four parts compositions, assembling process is simple, improves efficiency.
Two, this utility model is by moving back two claws claw mount pad and wedge-shaped slot simultaneously of hair device, expendable locked, to bringing great convenience property of assembly work.
Three, this utility model moves back in hair device and arranges needle body launch tube, improves the accuracy of blood sampling, decreases the pain of patient.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation Fig. 1;
Fig. 2 is structural representation Fig. 2 of the present utility model.
Detailed description of the invention
As Fig. 1, shown in 2, this utility model comprises housing 2, housing 2 one end is provided with pin cap 1, housing 2 inside is provided with column storage pin chamber 6, housing 2 internal face between storage pin chamber 6 and housing 2 is provided with wedge-shaped slot 21, storage is provided with needle body 4 in pin chamber 6, needle body 4 is connected with spring 5 by needle body mount pad 7, the hair device 3 of moving back that needle body mount pad 7 is arranged by housing 2 upper end is fixed on housing 2 inside, described hair device 3 of moving back fixes clamping by the elastic card claw 34 of both sides with housing 2 inwall, describedly to move back bottom hair device 3 respectively by claw 31, 32 with needle body mount pad 7, wedge-shaped slot 21 top connects, move back hair device 3 top center mutually in extendedly have needle body launch tube 33.
Composition graphs 1 sketches use procedure of the present utility model:
First hair device 3 of moving back of the present utility model contacted with the blood sampling site of patient, then pin housing 2 downwards, the claw 32 moving back hair device 3 slips in wedge-shaped slot 21, and drive claw 31 to discharge needle body mount pad 7, needle body 4 is launched under the effect of spring 5 elastic force simultaneously.
Technological means disclosed in this utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic combination in any.It should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
