Abstract
The utility model relates to a disposable blood sampler, characterized in that a blood-sampling needle is clipped on the clipping head of a needle-storing tube positioned in a holding device, and a plurality of blood-sampling needles are stored in the needle-storing tube. When the needle-storing tube is pressed, an aseptic blood-sampling needle is slid out from the needle-storing tube to replace the used blood-sampling needle on the clipping head, and the purpose that the blood-sampling needle can be used for one time. The phenomenon of the cross infection caused by the incomplete disinfection of the blood-sampling needle is fundamentally avoided. The utility model has the advantages of simple structure and convenient operation. The disposable blood sampler is suitable for the use of extensive medical units.
Description
This utility model relates to the medical diagnosis utensil, is a kind of blood sampling device.
Existing blood sampling hemostix is one and longly is the stainless pin of 63mm that its syringe needle place is the triangular edges needle point, gets the blood sampling of blood position with it at human body.This blood taking needle of hospital's use at present all is that turnover is used, the disinfectant solution sterilization is immersed in each back of using, but when using too frequently, often can not thoroughly sterilize because disinfecting time is not enough, and a lot of viruses can not be killed by general disinfectant solution, and cross infection just takes place easily for this, the particularly current world, domestic all in the propagation of viruses such as prevention AIDS and hepatitis that resorts to all kinds of methods, so changing traditional hemostix is current very urgent requirement.
This utility model provides a kind of novel structure, disposable blood taking device easy to use.Use the strict pre-pasteurized hemostix of this process, only use once because of its blood collection needles just to go out of use, just definitely avoided virus or pathogenic bacteria to propagate the possibility that cross infection takes place by hemostix.
This disposable blood taking device is made up of syringe needle, storage needle tubing and holder.Be shaped on bulge loop on the storage needle tubing periphery wall, its head is for vertically opening slotted resilient clamp head, but clamping syringe needle in the clamping head; Holder is the two ends diameter tube littler than mid portion diameter, is shaped on step on its cephalic par internal perisporium.During assembling the storage needle tubing is placed in the holder, and is with spring in storage needle tubing periphery between bulge loop and head, make an end of spring prop up bulge loop, the other end props up the step of holder.Can store standby syringe needle in the storage needle tubing, and tight at its tail end with pressing gag, in case outside contamination.Its user mode of such disposable blood taking device is that hand-held holder is aimed at syringe needle the human blood collection position and punctured epidermis and blood vessel rapidly, just can reach the purpose of blood sampling.After once using, lift the storage needle tubing and make the needle tubing clamping head stretch out holder.Then the rubber-like clamping head can unclamp voluntarily, simultaneously, heads on the breech face of syringe needle A immediately following the syringe needle (being called syringe needle B) of syringe needle (being called syringe needle A) in the clamping head moves down voluntarily under action of gravity; When decontroling pressing, the spring restoring force retreats the storage needle tubing, i.e. clamping head indentation holder under the promotion of spring tail end, advances clamping head to syringe needle B simultaneously, roof fall syringe needle A, and syringe needle B has just replaced syringe needle A.So continuous pressing and relieving pressing storage needle tubing just can reach the purpose of having been used syringe needle in clamping head by new aseptic syringe needle replacement.
The utility model has the advantages that: a syringe needle only uses once, avoided blood taking needle spread disease germs, virus possibility, and, in the storage needle tubing, dispose several syringe needles in the design of the present utility model, and adopt encapsulation back overall disinfection to make whole hemostix reach aseptic requirement, therefore, pressing is once store needle tubing in the use can have an aseptic syringe needle to change the function of that exhausted syringe needle, promptly a hemostix can use again for several times, has saved the funds expenditure.
Accompanying drawing is depicted as profile of the present utility model.
Most preferred embodiment of the present utility model as shown in drawings.Seen that by figure syringe needle 1 is clamped in the resilient clamp 2 of storage needle tubing 5 heads, this clamping head 2 be the glans penis shape, and its vertical position has 2 grooves, and its effect is to make clamping head generation elasticity.Be shaped on flange 6 on storage needle tubing 5 peripheries, it is bearing in an end of spring 4 in the use.Can store 11 syringe needles in storage needle tubing 5 inner chambers, afterbody disposes presses plug 8.This storage needle tubing 5 is placed in the holder 3.Holder 3 is slightly less than the tube of mid portion diameter for the two ends diameter, and the diameter at both ends matches with the external diameter of storage needle tubing 5, also is shaped on a step 9 on the head internal perisporium of this holder, for support spring 4 usefulness.Seen that by figure assembling medi-spring 4 is enclosed within storage needle tubing 5 outsides, and an end props up holder step 9, the other end props up bulge loop 6 on the storage needle tubing.In the present embodiment, be shaped on locating ring 7 on holder 5 internal perisporiums, make it prop up storage needle tubing bulge loop 6 during assembling, deviate from from the afterbody of holder 3 to place restrictions on storage needle tubing 5.
Claims (2)
1, the disposable blood taking device of a kind of its draw point head blade needle point triangular in shape, it is characterized in that also comprising holder 2, storage needle tubing 5 and spring 4, holder 2 is the two ends diameter tube more smaller than mid diameter, be shaped on step 9 on its head internal perisporium, be shaped on bulge loop 6 on storage needle tubing 5 periphery walls, its head is for opening slotted resilient clamp 2, and storage needle tubing 5 is placed in the holder 2, spring 4 be enclosed within storage needle tubing periphery and be installed on bulge loop 6 and step 9 between.
2, disposable blood taking device according to claim 1 is characterized in that being shaped on holder 2 internal perisporiums circle locating ring 7.
