Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of disposable anti-needle thorn vein blood taking needle.
Background technique
Blood sample collection is to send Clinical Lab to carry out clinical detection, and Testing index can be clinical disease diagnosis, control
It treats, prevention and Index for diagnosis provide reliable foundation.Clinically blood sample collection is divided into acquisition and the venous blood of arterial blood samples
The acquisition of the acquisition of sample, vein blood specimen generallys use Vacuum tube blood collection.
Vacuum tube blood collection is to be taken the lead in the 1940s releasing VACUTAINER vacuum blood collection system, 20th century by BD company
Blood collecting technology is further perfect within 80 years, and nowadays, the vacuum blood collection system with safety head is because it is with clean, safe, simple, fast
The advantages of prompt, accurate and reliable, economical and effective, is universal all over the world.
Currently, the vacuum blood collector clinically applied has split type blood taking needle and pen type blood collection.Split type blood taking needle
The disposable vein blood taking needle that namely current China's clinic generally uses, the note substantially used instead of eighties of last century
Emitter Blood collection is often used cooperatively with disposable vacuum blood collection tube, pen type blood collection clinical use not
It is more.
For clinically used split type blood taking needle, i.e., disposable vein blood taking needle clinically often has in this way
Nursing Risk: when blood sampling finishes, since the sharp needle point of blood collection needles is exposed outside, there is no any anti-needle thorn to protect at needle point
Protection unit, needle point are easy to stab nursing staff.Nursing staff is the high risk group that needle stabs generation, and needle, which is stabbed, can propagate 20
A variety of Hematogenic infectious diseases, it is caused by needle is stabbed that 80%~90% healthy medical staff, which suffers from Hematogenic infectious disease,.Needle is stabbed
Event not only results in the propagation of hematologic disease, and huge psychological pressure can be also caused to nursing staff.
U.S. CDC 2000 propose, safe design can to avoid 62%~88% injury from sharp utensil.In view of setting safely
Meter, occurs retraction type blood taking needle in the market, after the completion of blood sampling, using the isostructural elastic force of spring, syringe needle is retracted to one
In the structures such as the protective case for protecting syringe needle.Although energy effective protection syringe needle in this way, avoids medical worker from being wounded by stabbing, but
It can be because the mechanical action of needle retractable causes patient greatly painful.In addition, some blood taking needles use locked needle point or its
The anti-needling structure of his form, but production technology is more complicated, assembling is difficult, high production cost.
In conclusion clinical, there is an urgent need to one kind can effectively avoid needle stick injury, eliminate blood borne disease infection, and
Safe and reliable, simple production process, the blood taking needle utensil that assembling is easy, production cost is low.
Summary of the invention
In order to solve the above problems existing in the present technology, the utility model provides a kind of with the quiet of anti-needle thorn function
Arteries and veins blood taking needle, simple production process, assembling are easy, production cost is low and safe and reliable, easy to operate.
The utility model is solved the problems, such as by following technical proposals:

Specific embodiment
With reference to the accompanying drawing, the utility model is described further, but be not therefore limited in the utility model
Among the embodiment described range.As shown in Figure 1, the disposable anti-needle thorn vein blood taking needle that the present embodiment is related to, including
Blood sampling needle stand 1, blood-collecting needle tube 2, needle shield 3, hose 4, flexible tube base 5, bottle cork needle 7, blood-collecting needle tube 2 are mounted on blood sampling needle stand
On 1, needle shield 3 is arranged on needle stand 1 of taking a blood sample, the both ends of hose 4 are connect with blood sampling needle stand 1 and flexible tube base 5 respectively, flexible tube base 5
The other end connect bottle cork needle 7, it is characterised in that: disposable anti-needle thorn vein blood taking needle further includes covering in hose 4
On can be free to slide Needlestick prevention device 6 and the shield 8 that is connected on bottle cork needle 7.
As shown in Fig. 2, Needlestick prevention device 6 is hollow body, card slot 63 and track are provided on the tube wall of Needlestick prevention device 6
The junction of slot 64, card slot 63 and track groove 64 is provided with retention bead 65.
The setting of card slot 63 is in Needlestick prevention device proximal end 61, and the setting of track groove 64 is in Needlestick prevention device distal end 62, anti-needle thorn dress
Setting distal end (62) is curved opening shape.
Needlestick prevention device distal end 62 and the joint of track groove 64 are provided with guiding angle 66.
Specifically, the thickness of needle handle 11 is suitable with the opening width of track groove 64, and the opening width of retention bead 65 is along rail
The direction of road slot 64 to card slot 63 is gradually reduced, and the opening width of card slot 63 is slightly larger than the opening width of track groove 64.
Specifically, the axial length of Needlestick prevention device 6 is greater than the length of blood-collecting needle tube 2.
Specifically, Needlestick prevention device 6 is molded for integral type.
As shown in Figure 1, bottle cork needle 7 includes bottle cork needle needle stand 71, bottle cork needle needle tubing 72 and blood resistance unit 73,
Bottle cork needle needle tubing 72 is mounted on bottle cork needle needle stand 71, and blood resistance unit 73 is sheathed on outside bottle cork needle needle tubing 72, is prevented
Shield 8 is set to outside bottle cork needle needle tubing 72 and connect with 71 spiral of bottle stopper puncture needle stand needle stand.
The use process of the utility model: in use, according to conventional blood collection method, needle shield 3 is first pulled out, blood taking needle is passed through
Pipe 2 carries out venipuncture to patient, after puncturing successfully, shield 8 is connect with 71 spiral of bottle cork needle needle stand, and bottle stopper
Puncture needle tubing 72 be inserted into vacuum blood collection tube in, then under the suction function of vacuum blood collection tube, blood by blood-collecting needle tube 72,
Hose 4 is drawn into vacuum blood collection tube, completes blood sampling operation.
After blood sampling, vacuum blood collection tube is pulled out, blood-collecting needle tube 2 is extracted from patient body then, is pinched on the other hand after extraction
Firmly Needlestick prevention device 6, the other hand are pulled back hose 4 backward, and blood sampling needle stand 1 is pulled back to guiding angle 66, then proceedes to return backward
