Embodiment 1

Disposable anti-occupational exposure arterial blood air tube, as depicted in figs. 1 and 2, including blood gas needle ontology 1 and casing 2, blood The output end of air tube ontology 1 is provided with connector 11, and connector 11 is equipped with fixing pipe 12 far from one end of blood gas needle ontology 1, Gu Determine to be also provided with annular groove 13 on the outer wall of pipe 12, fixing pipe 12 is provided with syringe needle 14 far from one end of blood gas needle ontology 1.

Specifically, the outer wall of connector 11 is equipped with screw thread, and fixing pipe 12 is threadedly coupled with connector 11, is not only facilitated The replacement of connector 11, and connect also more secured.

Further, the arc-shaped shape in 13 bottom surface of annular groove, facilitates the fixation of casing 2.

In addition, fixing pipe 12 is made of polycarbonate, have hardness strong, it is not only harder the advantages of good antimicrobial effect Gu it is durable, also increase wholesomeness.

In the present embodiment, by the annular groove 13 and fixed ring 22 of setting, it is attached by lantern ring 2 and connector 11 When, it is only necessary to slightly firmly 22 sets of fixed ring are connected in annular groove 13, just casing 2 can be fixed, it is time saving and energy saving.

Embodiment 2

When specifically used, syringe needle 14 is exposed to the external world, it is easy to accidentally injure, to solve the above-mentioned problems, the present inventor exists Following change is made on the basis of embodiment 1, as shown in figure 3, one end of casing 2 offers telescopic chute 21, casing 2 is far from flexible It is symmetrically arranged with two fixed rings 22 on one end inner wall of slot 21, telescoping tube 23 is additionally provided in telescopic chute 21, telescoping tube 23 is close to solid One end periphery ring for determining ring 22 is provided with slip ring 231, and telescoping tube 23 is provided with rubber finger sleeve 24 far from one end of slip ring 231, Rubber finger sleeve 24 is provided with disk 25 far from one end of telescoping tube 23, and the central location of disk 25 offers circular hole 26.

Specifically, telescopic chute 21 is cylindrical, and the height of telescopic chute 21 is equal with the height of telescoping tube 23, convenient flexible Pipe 23 moves back and forth, and telescoping tube 23 can completely wrap up syringe needle 14 when stretching out.

Further, slip ring 231 and the inner wall of telescopic chute 21 are slidably connected, and slip ring 231 uses nitrile rubber system At having wearability strong, the advantages of good airproof performance, when sliding tube 23 slides up and down, can guarantee slip ring 231 and annular groove Leakproofness between 13 bottom ends, and then positive pressure and negative pressure can be generated.

Further, telescoping tube 23 takes the form of inclined plane far from one end periphery ring of slip ring 231, facilitate blood gas needle ontology 1 with The change of skin surface angle.

In addition, the diameter of circular hole 26 is 1.5 times of 14 diameter of syringe needle, guarantee to press from both sides between disk 25 and syringe needle 14 When angle, syringe needle 14 also can be passed through easily from circular hole 26 very much, and the sum of length of casing 2 and telescoping tube 23 is greater than syringe needle 14 Length 3mm guarantees completely wrap up syringe needle 14 in the case where telescoping tube 23 does not stress, and increases safety.

In the present embodiment, by the casing 2 and telescopic chute 21 of setting, facilitate telescoping tube 23 in telescopic chute 21 back and forth It is mobile, and under the action of slip ring 231, seal against each other slip ring 231 and the bottom of annular groove 13, and then in slip ring 231 can generate air pressure when mobile to 13 bottom end of annular groove, when slip ring 231 can also make under the influence of air pressure without stress Slip ring 231 drives telescoping tube 23 to move backward, and then can wrap up syringe needle 14, effectively avoids puncturing or pulling out needle When, syringe needle is exposed to the problem of external world be easy to cause scuffing, by the rubber finger sleeve 24 of setting, with preferable ductility, into And when in use, circular hole 26 is directed at the position that patient needs to puncture by medical staff, then that disk 25 and telescoping tube 23 is mutual Closer one end is as supporting point, under the action of the specific ductility of rubber finger sleeve 24 itself, when blood gas needle ontology 1 and skin table When angle between face changes, rubber finger sleeve 24 also can therewith telescoping tube 23 movement and generate deformation, and will not band The movement of dynamic disk 25, and then disk 25 can also be fitted closely with skin always, enable syringe needle 14 when passing through circular hole more Add stabilization.

The disposable anti-occupational exposure arterial blood air tube of the utility model when in use, by 12 company of being rotatably connected on of fixed ring On the outer wall of connector 11, then syringe needle 14 and connector 11 are sequentially passed through in casing 2 and telescoping tube 23, and by 2 sets of casing It is located on the outer wall of fixing pipe 12, then slightly exerts oneself, one end of 2 casees blood gas needle ontologies 1 of casing is mobile, and make slip ring 231 are socketed in annular groove 13, more time saving and energy saving casing 2 can be fixed；

When puncturing, circular hole 26 is directed at patient and needs the position that punctures, then by disk 25 and telescoping tube 23 mutually compared with As supporting point, medical staff adjusts angle when pillow 14 punctures for close one end, blood gas needle ontology 1 and skin surface it Between angle when changing, disk 25 can also be fitted closely with skin always, and then syringe needle 14 can when passing through circular hole It is more stable；

In injection, medical staff is mobile to skin penetrating point by blood gas needle ontology 1, will push casing 2, casing 2 at this time Telescoping tube 23 can be squeezed when moving, and telescoping tube 23 under the effect of the pressure can be to 21 contract of telescopic chute at this time, and then can Easily syringe needle 14 is pierced into, telescoping tube 23 moves in telescopic chute 21, and under the action of slip ring 231, makes slip ring 231 seal against each other with the bottom of annular groove 13, and then can generate air pressure when slip ring 231 is mobile to 13 bottom end of annular groove, when When injection is completed, blood gas needle ontology 1 drives syringe needle 14 mobile to separate skin side, at this time in slip ring 231 and annular Between 13 bottom end of slot under the action of air pressure, telescoping tube 23 will not be moved with the movement of casing 2, and then when syringe needle 14 is received completely Hui Shi, position of the syringe needle between telescoping tube 23 and disk 25, and it is fully wrapped around by telescoping tube 23, it can be avoided syringe needle 14 Skin is caused to scratch, increases the safety used.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Be only the utility model preference, be not intended to limit the utility model, do not departing from the spirit and scope of the utility model Under the premise of, the utility model also has various changes and improvements, these changes and improvements both fall within claimed it is practical In novel range.The protection scope of the present invention is defined by the appended claims and their equivalents.
