Description
Technical field
This utility model relates to the technical field of medical apparatus and instruments, particularly be a kind of guiding blood taking needle.
Background technology
Venous blood collection is a common clinical manipulation, also be the diagnosis and treatment communication process that cannot ignore, the unsuccessful meeting of venipuncture causes invalid fixing and needle point the stabbing blood vessel of vein blood taking needle, and make blood collection procedure not smooth, not only increase patient suffering, affect nurse-patient relationship harmony, cause specimen oligemia simultaneously, serious may puncture again, affects work efficiency.Therefore, how fixing more cleverly blood taking needle, reduce puncture again, improve venous blood collection success rate, reduce patient's misery, increase work efficiency, is the actively problem of thinking of nursing staff.
Utility model content
The technical problems to be solved in the utility model has been to provide a kind of guiding blood taking needle that improves blood sampling success rate.
The technical solution of the utility model is as follows:
A kind of guiding blood taking needle, comprise syringe needle, blood taking tube, handle and handle set, front end at described blood taking tube is provided with arm, and described arm front end is connected perforation with the front end of blood taking tube, is also connected and is through with syringe needle pipe box at the front end of described blood taking tube and arm junction; In described arm, be socketed with blood resistance unit, the rear end of this blood resistance unit is socketed with syringe, and a side of this syringe is provided with opening chute backwards, and described syringe needle is arranged in syringe, the rear end of described syringe needle is connected with handle set, and this handle set is slidably connected through chute and syringe.
Adopt above structure, the syringe needle part of common blood taking needle is separated, be placed in separately in a syringe, the rear end of syringe needle is connected with handle set, and this handle set passes the chute of syringe one side and is slidably connected with syringe; When puncture, the front end of syringe and the socket of the rear end of blood resistance unit, driving handle forward, drive syringe needle through blood resistance unit, arm and syringe needle pipe box, syringe needle penetrates after blood vessel, syringe needle pipe box also penetrates blood vessel thereupon, now pulling back handle takes syringe needle out of and syringe needle is got back in syringe again, can avoid the blood taking needle damage to blood vessel in blood vessel for a long time, reduce patient's misery, improved blood sampling success rate, syringe needle has been drawn back to syringe and greatly reduced medical personnel's occupational exposure rate, work efficiency is improved.
For effectively fixing syringe, reduce the probability of puncture again, ensure that nurse can carry out bimanualness in connecting, changing blood sampling test tube process simultaneously, reduce and prepare to apply ointment or plaster or time of medical proof fabric, increase work efficiency, as preferably, described handle is provided with outer handle and interior handle two parts, described outer handle and interior handle are heavily incorporated in the same side gemel connection, all scribble and paste agent on the top layer of described outer handle and interior handle.
For fixing syringe and blood resistance unit, ensure that syringe needle steadily penetrates and extracts, as preferably, the rear end of described blood resistance unit is provided with draw-in groove, and the outside of described syringe front end is provided with the projection suitable with draw-in groove, and this projection and draw-in groove connect and fix.
Beneficial effect: this utility model is separated syringe needle from blood taking tube, be placed in separately in a syringe, after completing, puncture draws back syringe needle, while having avoided blood drawing, cause puncture wound, reduce patient's misery, improved blood sampling success rate, greatly reduced medical personnel's occupational exposure rate, work efficiency is improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this utility model is made up of syringe needle 1, blood taking tube 2, handle 3 and handle set 9 etc., be provided with arm 4 at the front end of described blood taking tube 2, described arm 4 front ends are connected perforation with the front end of blood taking tube 2, are also connected and are through with syringe needle pipe box 5 with the front end of arm 4 junctions at described blood taking tube 2; In described arm 4, be socketed with blood resistance unit 6, the rear end of this blood resistance unit 6 is socketed with syringe 7, the rear end of described blood resistance unit 6 is provided with draw-in groove, outside at described syringe 7 front ends is provided with the projection suitable with draw-in groove 10, this projection 10 connects and fixes with draw-in groove, and a side of this syringe 7 is provided with opening chute 8 backwards, and described syringe needle 1 is arranged in syringe 7, the rear end of described syringe needle 1 is connected with handle set 9, and this handle set 9 is slidably connected through chute 8 and syringe 7.
