Description

A kind of venous blood-taking apparatus

Technical field:

The utility model relates to medical device more particularly to a kind of venous blood-taking apparatus.

Background technique:

In the curative activity of hospital, by acquiring venous blood sample, specific indexes is chemically examined, are that doctor is common Diagnosis basis.In recent years, hospital gradually adopts the form of blood taking needle cooperation vacuum tube to acquire venous blood sample, works as needs When acquiring more parts of blood samples, usually there are two types of mode: the first, need to puncture patient's vein repeatedly, every acquisition portion sample, More transducer set blood taking needle and vacuum tube；Second, patient's vein need to be only punctured, a sample of every acquisition is replaced primary true Blank pipe, then the rubber seal plug of the vacuum tube newly changed is punctured, carry out the acquisition of lower a sample.It is asked existing for above two mode Topic is: puncturing patient's vein repeatedly, increases the pain of patient, and cause the waste of medical instrument, increase chemical examination cost； The rubber seal plug for puncturing the vacuum tube newly changed repeatedly not can guarantee entire blood collection procedure and carry out in gnotobasis, blood sample This is easy accuracy that is contaminated, and then influencing result of laboratory test；Replacement vacuum tube can also touch blood taking needle repeatedly, and traditional Blood taking needle is fixed on the arm of patient by medical adhesive tape, when pulling out needle after the completion of blood sampling, during tearing adhesive tape It is possible that blood taking needle can be touched, vein is caused to be punctured, meanwhile, Blood specimen collection inefficiency；In addition, common disposable When blood taking needle carries out waste disposal after the completion of blood sampling, the process cartridge for being either put into profession still takes needle guard, all there is doctor The danger that business personnel are stabbed by blood taking needle, or even will cause hepatitis B, hepatitis disease that medical worker is adhered in blood collection needles The serious consequences such as poison and AIDS viral infection.

Utility model content:

The purpose of this utility model is to provide one kind securely and reliably, blood sampling efficiency can be improved, reduce the quiet of patient suffering Arteries and veins blood-taking device.

The utility model is implemented by following technical solution:

A kind of venous blood-taking apparatus comprising heparin tube, blood taking needle, current divider, connector and vacuum tube；

Detailed description of the invention:

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.

Fig. 1 is the positive structure schematic of the present embodiment.

In figure: heparin tube 1, blood taking needle 2, current divider 3, switch 4, connector 5, vacuum tube 6, isocon 7, wing handle 8, Fixing belt 9, sheath 10, casing 10-1, squeezing handle 10-2, sliding slot 10-3, limiting slot 10-4.

Specific embodiment:

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment 1:

A kind of venous blood-taking apparatus as shown in Figure 1 comprising heparin tube 1, blood taking needle 2, current divider 3, connector 5 and Vacuum tube 6；

One end of heparin tube 1 is connected to blood taking needle 2, and the other end of heparin tube 1 is connected to a port of current divider 3, point It flows and is equipped with switch 4 on remaining port of device 3, each switch 4 is connect with a connector 5, and connector 5 and vacuum tube 6 connect It is logical；It further includes isocon 7, and switch 4 is connected to connector 5 by isocon 7.Multiple vacuum tubes 6 can be once accessed to carry out Blood sampling, is greatly saved blood sampling time, improves blood sampling efficiency, while reducing pain when patient's blood sampling.

It further includes handle, and handle is set on blood taking needle 2, and handle is wing handle 8, is connected on wing handle 8 solid Determine band 9, fixing belt 9 is equipped with attachment device, and attachment device is thread gluing or snap-fastener, can play immobilized patients arm and blood taking needle 2 Effect, entire blood collection procedure can avoid the case where being touched, vein is caused to be punctured of blood taking needle 2.

It further includes sheath 10, and sheath 10 includes the squeezing handle 10-2, casing 10-1 and squeezing handle 10- of casing 10-1 and hard 2 are sheathed on heparin tube 1, and one end of squeezing handle 10-2 is fixedly connected with casing 10-1 far from one end of wing handle 8；It is covering The sliding slot 10-3 to match with the fin of wing handle 8 is offered on pipe 10-1, and limiting slot 10-4 is offered on squeezing handle 10-2, Sliding slot 10-3 is connected to limiting slot 10-4, and the width of sliding slot 10-3 is gradually reduced by the direction of blood taking needle 2 to wing handle 8, The width of sliding slot 10-3 and the sliding slot 10-3 of the junction limiting slot 10-4 are less than the width of limiting slot 10-4, the height of limiting slot 10-4 Degree is greater than the height of the fin of wing handle 8；After blood sampling, it can be pulled on the other hand by the squeezing handle 10-2 of a hand grip hard Heparin tube 1 makes the fin of wing handle 8 have sliding slot 10-3 to slide into limiting slot 10-4, and then makes blood taking needle 2 that can bounce back to shield In set 10, since squeezing handle 10-2 uses hard material, limiting slot 10-4 will not be loose because of external force, the wing of wing handle 8 Piece would not also skid off limiting slot 10-4, thus more safe and reliable.

Casing 10-1 is designed as inclined-plane or curved surface far from the one end of the squeezing handle 10-2, and the minimum point on inclined-plane is sliding slot The fin of the import department of 10-3, wing of being more convenient for handle 8 enters in sliding slot 10-3.The lower end oral area and limiting slot of sliding slot 10-3 The oral area of 10-4 deviates, shift ratio 1:3；It is also contemplated that the fin of wing handle 8 is living in the middle position of limiting slot 10-4 Dynamic probability is larger, and the offset setting of the oral area of the lower end oral area of sliding slot 10-3 and limiting slot 10-4 can further be limited blood sampling Needle 2 is exited from sheath 10.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
