Description
Technical field
Blood taking needle field is the utility model is related to, more particularly, to a kind of disposable medical blood taking needle.
Background technology
Directly abandoned after current medical blood-sampling needle use；In the later stage in the processing of medical waste, exposed syringe needle is deposited
In larger potential safety hazard, garbage reclamation personnel are easily stabbed, cause cross-infection.Although needle cap, which returns set, can play protection work
With, but finger is easily stabbed during set is returned, high risk is equally existed, and most of hospitals prohibite needle cap at present
Return set.
Utility model content
In order to overcome the technical deficiency of existing blood taking needle, the utility model provides a kind of disposable medical blood taking needle, energy
It is enough to shrink exposed syringe needle, reduce the risk of accidental injury.
Technical scheme is used by the utility model solves its technical problem：A kind of disposable medical blood taking needle, including
Syringe needle, needle guard, heparin tube, the pin wing；In the tail end insertion needle guard of syringe needle, the head end of needle guard is fixedly connected with sleeve, the tail end of needle guard
Heparin tube is connected, needle guard both sides are fixedly connected with the pin wing；Needle guard is provided with square notch, square notch in the middle position of two pin wings
Place is flexibly connected gear shaft；The rear end surface of the syringe needle is provided with the latch that can be engaged with gear shaft, and the gear shaft passes through
The mode engaged with latch is flexibly connected the tail end of syringe needle；Row's elastic spacing block, elastic spacing block and pin are provided with inside needle guard
Latch contact on head, the elastic spacing block are tilted by the head end of needle guard towards tail end direction.
Further, the length of the needle guard is more than the length of syringe needle.
Further, the needle guard, the pin wing, gear shaft, sleeve are plastic materials.
The beneficial effects of the utility model are the disposable medical blood taking needles, can shrink exposed syringe needle after use
To sleeve, syringe needle is difficult to voluntarily stretch out in sleeve, advantageously reduces the accidental injury risk in subsequent treatment.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation inside needle guard.
Indicated in figure, 1. syringe needles, 2. needle guards, 3. heparin tubes, the 4. pin wings, 5. square notches, 6. gear shafts, 7. latches, 8.
Elastic spacing block, 9. sleeves.
Embodiment
Reference picture 1-2, a kind of disposable medical blood taking needle, including syringe needle 1, needle guard 2, heparin tube 3, the pin wing 4；Syringe needle 1
In tail end insertion needle guard 2, the head end of needle guard 2 is fixedly connected with sleeve 9, and the tail end connection heparin tube 3 of needle guard 2, the both sides of needle guard 2 are fixed
Connect the pin wing 4；Needle guard 2 is provided with square notch 5 in the middle position of two pin wings 4, and gear shaft 6 is flexibly connected at square notch 5；
The rear end surface of the syringe needle 1 is provided with the latch 7 that can be engaged with gear shaft 6, and the gear shaft 6 with latch 7 by engaging
Mode is flexibly connected the tail end of syringe needle 1；The inside of needle guard 2 is provided with row's elastic spacing block 8, elastic spacing block 8 and the card on syringe needle 1
Tooth 7 is contacted, and the elastic spacing block 8 is tilted by the head end of needle guard 2 towards tail end direction.
Preferably, the length of the needle guard 2 is more than the length of syringe needle 1.
Preferably, the needle guard 2, the pin wing 4, gear shaft 6, sleeve 9 are plastic materials.
The utility model is in blood sampling in use, because syringe needle 1 and the inwall of needle guard 2 are in close contact, so syringe needle 1 is being pierced into skin
It will not be shunk during skin, syringe needle 1 can also be pierced into skin when pressing gear shaft 6, prevent from shrinking；After blood sampling use, slide teeth
Wheel shaft 6 drives syringe needle 1 to be contracted in sleeve 9 by latch 7, and elastic spacing block 8 can carry out spacing to latch 7, syringe needle 1 is existed
Not by be difficult in the case of external force stretch out sleeve 9.
