Description
Technical field:
The utility model is related to mankind life article more particularly to medical instrument, particularly a kind of blood taking needle.
Background technology
Blood sampling chemical examination is the important means of modern medicine auxiliary examination, and the prior art is completed using blood taking needle and heparin tube
Initial blood collection procedure is chemically examined, at present blood taking needle of the countries in the world hospital caused by syringe needle fracture or medical staff's misoperation
Tribal chief's body injury accident occurs millions of person-times every year.The statistical data that American Medical Association announces shows that medical worker suffers from blood source
Property disease 80%-90% be caused by needle is stabbed, separately there is 8.6% to come from blood injection or pollution, above-mentioned accident mainly occurs
In blood collection procedure.At present, common disposable blood taking needle in manufacture to needle guard on pinhead sleeve to protect syringe needle, when use, pulls out
Fall or easily cause pricking hazard when putting on needle guard, extract blood sampling out of person of blood collecting body particularly after the completion of blood sampling
When needle carries out waste disposal, once the serious consequences such as medical staff infection can be caused by being wounded by stabbing.For this defect, some blood samplings
Needle employs the technological means of retractable needle, and syringe needle is retracted in the structures such as protective case using elastic force after the completion of blood sampling.
So, although can be wounded by stabbing to avoid medical worker, but can be because the mechanical action of needle retractable causes patient's pain
It is bitter.On the other hand, the straight tube for being used to be inserted into vacuum blood collection tube of the blood taking needle hose other end, when in use, puts forth effort because lacking
Point, it is not easy to plug or easily slotting inclined, and also also there is infection medical worker or the contaminated wind of blood sample in the straight tube for lacking protection
Danger.Thus, there are production cost is high, complicated, Patient Experience is undesirable, security function for the safety blood taking equipment of the prior art
The defects of not comprehensive.
Utility model content
The purpose of this utility model is that for drawbacks described above of the prior art, provide one kind effectively prevent needle stab and
The generation of contact blood infection and the safety blood taking needle device for not increasing patient suffering.
Its main operational principle is the operation portion by setting the protective cover with stretching structure that syringe needle is made only to expose in blood sampling
Part is located at syringe needle rear, before in syringe needle stretching or the operation of retraction protective cover, the hand of medical staff is not required to appear in syringe needle, Du
Needle thorn risk absolutely, by setting straight tube sleeve, medical staff avoids the contact with straight tube, avoids contact blood infection
Risk, the contaminated situation of blood sample will not occur, due to the design of non-stretchable retraction formula syringe needle, will not increase to patient
Add additional pain.
To achieve the above object, the utility model uses following technical scheme：A kind of safety blood taking needle device, including needle
Seat, syringe needle, for being inserted into the straight tube of vacuum blood collection tube, straight tube seat, one end of the needle stand is fixed and connects the syringe needle,
The other end is connected by hose with the straight tube seat, one end of straight tube seat connection hose, and the other end is fixed and connected described
Straight tube, wherein, needle stand handle on the needle stand is set, is cased with protective cover on the outside of the syringe needle and needle stand, the protective cover is in
The tubular of both ends open, the side of protective cover are provided with sliding groove, and the needle stand handle stretches out protection by the sliding groove
It covers and forms sliding pair with sliding groove, needle stand handle, which is moved to, drives the fully extended protective cover of syringe needle, needle stand handle when sliding front of the slot
Syringe needle is driven to be entirely retracted within protective cover when being moved to sliding groove rear end, sliding groove rear end is provided with narrowing spacing bayonet, needle
Seat handle is by spacing bayonet of narrowing by needle locking in the state being entirely retracted in protective cover.
Further, needle spacing bayonet is provided in the slip front of the slot, and the needle stand handle can be by going out needle spacing bayonet
By state of the needle locking outside fully extended protective cover.
Further, the needle stand handle is made of elastic material.
Further, straight tube sleeve, the straight tube sleeve one end open other end and straight tube seat are provided with outside the straight tube
Straight tube is sleeved in it by fixation completely, and the length of the straight tube sleeve is more than straight tube and internal diameter is more than vacuum blood collection tube.
Further, one circle protrusion of setting on the outside of the straight tube sleeve openings end.
Further, the straight tube sleeve is made of clear material.
The utility model compares with prior art, and effect is positive and apparent.The utility model effectively avoids curing
Shield personnel occur needle thorn risk or because of contact being in contact property of straight tube blood infection or pollution blood samples, simple in structure, make
It is low with convenience, production cost.

Specific embodiment：
Embodiment:
As shown in Figures 1 and 2, safety blood taking needle device, including needle stand 2, syringe needle 1, for being inserted into the straight of vacuum blood collection tube
Pipe 9, straight tube seat 12, described 2 one end of needle stand are fixed and connect the syringe needle 1, and the other end is connected by hose 8 with straight tube seat 12,
Described 12 one end of straight tube seat connects hose 8, and the other end is fixed and connects the straight tube 9, which is characterized in that is set on the needle stand 2
Needle stand handle 3 is put, the syringe needle 1 and 2 outside of needle stand are cased with protective cover 4, tubular of the protective cover 4 for a both ends open, institute
It states 4 side of protective cover and is provided with sliding groove 5, the needle stand handle 3 is stretched out in except the protective cover 4 simultaneously by the sliding groove 5
The sliding groove 5 can be prolonged to move, the needle stand handle 3 drives the 1 fully extended guarantor of syringe needle when being moved to 5 front end of sliding groove
