Description
Technical field
The utility model relates to medical equipment technical field more particularly to a kind of disposable blood sample collectors.
Background technique
Currently, common hemostix used in medical institutions, is mostly made of needle stand and sleeve, the end connection of needle stand
Blood taking needle, the syringe needle that the other end of needle stand injects in set letter then connect with vacuum blood collection tube.Hemostix is disposable medical treatment
Equipment, when having drawn blood extraction, exposed syringe needle easily causes medical staff to accidentally injure, and the needle exposed in waste treatment
Head can also accidentally injure other people, cause to infect, bring and be difficult to expect danger.And existing hemostix adds mostly on the syringe needle of blood taking needle
The needle cover of separate type, but inconvenient for use and easy loss, medical staff forgets to give pinhead sleeve needle cover after use, or gives up in processing
Needle cover falls off when abandoning hemostix, all easily makes syringe needle exposure.Meanwhile hemostix in the market is directly connect with vacuum blood collection tube, no
It can see blood back, can not judge whether puncture succeeds, make troubles to medical staff, also bring pain to sufferer.
Utility model content
And a kind of safely and conveniently disposable blood sample visual the technical problem to be solved by the utility model is to provide blood back
Collector.

Device includes the puncture portion being placed in sleeve barrel chamber made of transparent material；The front end of the sleeve is equipped with puncturing hole, and its rear end is set
There is perforation hole；The top front end of the sleeve is equipped with preceding clamping part, and its rear end is equipped with rear clamping part, the preceding clamping part and rear buckle
The sleeve wall between portion is equipped with sliding rail；The puncture portion sets needle made of hollow lumen and transparent material in including
Seat；The needle stand is equipped with radially projecting snap arm, which is placed on the sliding rail and initial position is fitted into described
Clamping part, final position are fitted into the preceding clamping part afterwards；One end of the hollow lumen is equipped with venipuncture needle, the other end
Equipped with hose, which passes through the perforation hole stretching sleeve and end is connected with pipe close puncture needle；The venipuncture needle
The sleeve is stretched out across the puncturing hole.
The outside of the puncturing hole and the preceding clamping part and the sliding rail is equipped with the overlay film being linked together, the overlay film
It is equipped in the sliding rail close to the position of the rear clamping part and pulls open portion.
The equal thermoplastic in outside of the puncturing hole and the preceding clamping part and the sliding rail has overlay film.
Compared with the prior art, the utility model has the following advantages:
1, the utility model middle sleeve wall is equipped with sliding rail, and needle stand is equipped with radially projecting snap arm, which can
It slides in the sliding track, and then moves needle stand in sleeve, to shrink syringe needle, not only easy to use, sleeve is not easy to lose
It loses and prevents medical staff from accidentally injuring with the syringe needle that other people are exposed, effectively increase safety.
2, the utility model middle sleeve and needle stand are that transparent material is made, so that blood back is visual, facilitate medical staff quasi-
Really judge whether to puncture blood vessel.
3, the outside of puncturing hole and preceding clamping part and sliding rail is equipped with the overlay film being linked together in the utility model, this is covered
Film is equipped with close to the position of rear clamping part in sliding rail and pulls open portion so that the utility model before blood sampling in completely enclosed and
Sterile state.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the utility model static condition structural schematic diagram.
Fig. 2 is the utility model blood sampling status architecture schematic diagram.
Fig. 3 is the utility model sleeve blood sampling state schematic perspective view.
In figure: 1- puncture portion, 100- needle stand, 101- venipuncture needle, 102- hose, 103- hollow lumen, 104- snap arm,
Clamping part, 204- sliding rail after clamping part, 203- before 105- pipe close puncture needle, 2- sleeve, 201- puncturing hole, 202-.
Specific embodiment
As shown in Fig. 1 ~ 3, a kind of disposable blood sample collector, the collector includes being placed in sleeve 2 made of transparent material
Puncture portion 1 in barrel chamber.
The front end of sleeve 2 is equipped with puncturing hole 201, and its rear end is equipped with perforation hole；The top front end of sleeve 2 is equipped with preceding clamping part
202, its rear end is equipped with rear clamping part 203, and 2 wall of sleeve between the preceding clamping part 202 and rear clamping part 203 is equipped with sliding rail
Road 204.
Puncture portion 1 sets needle stand 100 made of hollow lumen 103 and transparent material in including；Needle stand 100 is equipped with radial prominent
Snap arm 104 out, which is placed on sliding rail 204 and initial position be fitted into it is embedding to rear clamping part 203, final position
Clamping part 202 before being bonded to；One end of hollow lumen 103 is equipped with venipuncture needle 101, and the other end is equipped with hose 102, the hose
102 across perforation hole stretching sleeve 2 and end is connected with pipe close puncture needle 105；Venipuncture needle 101 is stretched out across puncturing hole 201
Sleeve 2.
Wherein: the outside of puncturing hole 201 and preceding clamping part 202 and sliding rail 204 is equipped with the overlay film being linked together, this is covered
Film is equipped with close to the position of rear clamping part 203 in sliding rail 204 and pulls open portion.
The equal thermoplastic in outside of puncturing hole 201 and preceding clamping part 202 and sliding rail 204 has overlay film, the drawing for overlay film of being more convenient for
Open the use with the utility model.
Needle stand 100 and sleeve 2 are transparent material.It, can be in vein by hollow lumen 103 in transparent needle stand 100
After puncturing pin puncture success, it is seen that whether blood flows into hollow lumen 103 from venipuncture needle, succeed to judge to puncture.
When static condition before the utility model is in use, snap arm 104 is chimeric with rear clamping part 203, venipuncture
Needle 101 is accommodated in sleeve 2, and overlay film makes the utility model be in completely enclosed and sterile state.When blood sampling, overlay film is pulled open
Pull open portion, uncover overlay film successively from sliding rail 204, preceding clamping part 202 and puncturing hole 201, above pushing away snap arm 104 makes to puncture
Portion 1 is moved along sliding rail 204, until snap arm 104 is chimeric with preceding clamping part 202, thus by venipuncture needle 101 from puncture
Hole 201 is released, and sleeve 2 is held, and venipuncture needle 101 is pierced into blood vessel.Snap arm 104 is fitted and fixed with preceding clamping part 202 at this time,
It shake the syringe needle in blood sampling of venipuncture needle 101 will not, facilitate blood sampling.Venipuncture needle 101 by hollow lumen 103 with it is soft
Pipe 102 be connected to so that venipuncture needle 101 punctures successfully after blood from hollow lumen 103 flow into hose 102, and then inflow and
In the vacuum blood collection tube that pipe close puncture needle 105 is connected.
After blood sampling, snap arm 104 is pushed backward along sliding rail 204, keeps snap arm 104 and rear clamping part 203 embedding
It closes, to venipuncture needle 101 be stored back in sleeve 2, so that preventing venipuncture needle 101 to be detached from sleeve 2 accidentally injures medical care people
Member and other people.
