Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to a kind of remaining needle with sensitive blood-return function.
Background technology
Medical personnel carry medicine for the patient, the most basic requirement is to want safe infusion, existing disposable infusion remaining needle, be difficult for observing blood back during puncture, this makes the nurse be difficult to the depth degree of control puncture, can not judge fast whether needle point thrusts in the blood vessel, and repeated localised puncture can cause suffering to patient.
Summary of the invention
At above-mentioned deficiency, the object of the present invention is to provide kind simple in structurely, only need in existing disposable use remaining needle, install a sensitive blood back flowing device additional, reach quick and judge whether needle point thrusts in the blood vessel, solve the sensitive blood return indwelling needle of the accurate problem of puncture.
The objective of the invention is to realize by following technical scheme, it comprises draw point, flexible pipe, suitable pin device, soft seal body and shell body, install a sensitive blood back flowing device at the shell body rear portion, the flexible pipe rear end is inserted into the shell body front end, and along the pin device that flexible pipe rear end and shell body inwall chucking is fixing, the soft seal body is installed in the shell body, draw point passes the soft seal body, preceding half section is inserted in the flexible pipe, exposes the draw point point, and the draw point afterbody links to each other with sensitive blood back flowing device.
Described sensitive blood back flowing device is made of the outer support member of air bag, air bag, air bag inner supporting member, and the air bag opening place struts with the air bag inner supporting member, is installed in together in the outer support member of air bag, and chucking is fixing.
Described air bag inner supporting member is established a through hole, makes air bag inner logical extraneous.
Described draw point afterbody is plugged on the outer support member front end of air bag, and fixing, and the outer support member cavity of draw point cavity and air bag is connected.
Described shell body sidewall is established a feed tube.
Establish the single-blade needle handle on the outer support member of described air bag.
Advantage of the present invention is:
1, can judge the blood back situation fast in medical personnel's transfusion, alleviate working strength, reduce misery to patient;
2, product operation is convenient, is beneficial to clinical expansion and uses;
3, structure and processing technology are simple, and cost is low, and boundless market prospect is arranged.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.

Among the figure: 1. draw point, 2. flexible pipe is 3. along the pin device, 4. soft seal body, 5. shell body, 6. sensitive blood back flowing device, 7. outer support member, 8. air bag, 9. air bag inner supporting member of air bag, 10. feed tube, 11. draw point points, 12. single-blade needle handles, 13. conduit, 14. transfusion and dosing threeways, 15. straight integrated circuit boards end, 16. the transfusion interface, 17. dosing mouths.
The specific embodiment
The described sensitive blood return indwelling needle of present embodiment, as shown in Figure 1, it comprises draw point 1, flexible pipe 2, suitable pin device 3, soft seal body 4 and shell body 5, installs a sensitive blood back flowing device 6 at shell body 5 rear portions, and flexible pipe 2 rear ends are inserted into shell body 5 front ends, along pin device 3 that flexible pipe 2 rear ends and shell body 5 inwalls chucking are fixing, soft seal body 4 is installed in the shell body 5, and draw point 1 passes soft seal body 4, and preceding half section is inserted in the flexible pipe 2, expose draw point point 11, draw point 1 afterbody links to each other with sensitive blood back flowing device 6.
As shown in Figure 2, described sensitive blood back flowing device 6 is made of the outer support member 7 of air bag, air bag 8, air bag inner supporting member 9, and air bag 8 opening parts strut with air bag inner supporting member 9, is installed in together in the outer support member 7 of air bag, and chucking is fixing.
Described air bag inner supporting member 9 is established a through hole, makes air bag 8 inner logical extraneous.
Described draw point 1 afterbody is plugged on outer support member 7 front ends of air bag, and fixing, and outer support member 7 cavitys of draw point 1 cavity and air bag are connected.
Described shell body 5 sidewalls are established a feed tube 10.
Establish single-blade needle handle 12 on the outer support member 7 of described air bag.
Use principle:
As shown in Figure 3, the feed tube 10 of sensitive blood return indwelling needle links to each other with transfusion and dosing threeway 14 by conduit 13, and establishing always on the conduit, integrated circuit board ends 15.During transfusion, liquid enters conduit 13 by transfusion and dosing threeway 14, and the feed tube 10 through shell body 5 sidewalls enters in shell body 5 cavitys again.At this moment, medical personnel's closing liquid flows, and draw point point 11 and flexible pipe 2 front ends begin to thrust vein blood vessel, runs into not find blood vessel accurately when not having blood back, and then the air bag in the sensitive blood back flowing device 8 does not change; When finding blood vessel, after blood refluxed, because the pressure effect, 8 moments of air bag contracted flat; So can show blood back fast, can help the nurse to control the depth degree of puncture smoothly like this, judge fast whether needle point thrusts in the blood vessel, solve the accurate problem of puncture.As Fig. 4, shown in Figure 5, extract sensitive blood back flowing device 6 and draw point 1 afterwards, soft seal body 4 closures are opened straight integrated circuit board and are ended 15, the remaining needle transfusion.
Transfusion finishes, and flexible pipe 2 continues to be retained in the blood vessel, uses the Adhesive plaster for transfusion fixed outer, and do not need to puncture when infusing next time again.
