Abstract
The utility model relates to a syringe needle subassembly for needle is kept somewhere to vein, including casing seat and stainless steel pjncture needle, the stainless steel pjncture needle includes solid needle body and needle handle, and the casing seat front end is equipped with the hose of keeping somewhere that wraps up solid needle body, and the needle point portion of solid needle body is equipped with back the blood hand -hole, is equipped with back blood and portals on the solid needle body in keeping somewhere the hose, is equipped with in the solid needle body to communicate back the blood hand -hole and return time blood passageway that blood portals. The utility model relates to a rationally, the pjncture needle adopts solid needle body, and the front end of solid needle body is equipped with back the blood hand -hole for the cone form on the circular conical surface, have back blood to portal on the needle body, and consequently time blood observation is convenient, and the patient is painful during the puncture feels little, is difficult for haring the blood vessel, and the simultaneous processing required precision is low, processing convenience, low in production cost.
Description
Technical field
This utility model relates to a kind of needle assembly, particularly a kind of venous detaining needle needle assembly.
Background technology
Venous detaining needle, owing to can reduce the damage of repeatedly puncturing and the misery of transfusion outpatient, is subject to the welcome of increasing clinical staff to the advantage such as the stimulation of blood vessel is little during transfusion.The piercing process of venous detaining needle plastic bushing intravasation by a hollow stainless pin pipe racks, when seeing blood back from sleeve pipe, representing and puncturing successfully, extracting rustless steel needle tubing, and plastic bushing indwelling Ink vessel transfusing is carried out the process of infusing.But this traditional hollow puncture needle tubing is very high for the processing request of needle tubing sword face, cutting edge, must not have the defect such as burr, burr, otherwise the needle tubing of very easily injured patient.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provide a kind of reasonable in design, structure simply, the venous detaining needle needle assembly of not easily injured blood vessel.
Technical problem to be solved in the utility model is realized by following technical scheme, this utility model is a kind of venous detaining needle needle assembly, comprise casing seat and rustless steel puncture needle, be characterized in: described rustless steel puncture needle comprises solid needle body and needle handle, casing seat front end is provided with the indwelling flexible pipe wrapping up solid needle body, the needle tip of solid needle body is provided with blood back hand-hole, the solid needle body be in indwelling flexible pipe is provided with blood back and portals, and is provided with the blood back passage being communicated with blood back hand-hole and blood back and portalling in solid needle body.
Utility model technical problem to be solved can also be realized further by following technical scheme, and the front end of described solid needle body is cone shape, and described blood back hand-hole is located on taper seat.
Utility model technical problem to be solved can also be realized further by following technical scheme, and described blood back hand-hole and the blood back homonymy that portals is arranged on solid needle body.
Utility model technical problem to be solved can also be realized further by following technical scheme, and described blood back hand-hole and blood back portal and be symmetricly set on the both sides of solid needle body.
Utility model technical problem to be solved can also be realized further by following technical scheme, described blood back hand-hole comprises the first blood back hand-hole and the second blood back hand-hole, blood back portal comprise the first blood back portal and the second blood back portal, blood back passage comprises the first blood back passage and the second blood back passage, first blood back hand-hole and the first blood back portal, second blood back hand-hole and the second blood back branch's homonymy that portals is arranged on solid needle body, first blood back hand-hole and the first blood back are portalled and to be connected by the first blood back passage, second blood back hand-hole and the second blood back are portalled and to be connected by the second blood back passage.
Compared with prior art, this utility model is reasonable in design, and puncture needle adopts solid needle body, and the front end of solid needle body is cone shape, taper seat is provided with blood back hand-hole, needle body has blood back portal, therefore blood back is observed conveniently, and during puncture, patient pain feels little, not easily injured blood vessel, requirement on machining accuracy is low, easy to process simultaneously, and production cost is low.

Fig. 2 is another kind of structural representation of the present utility model.
Fig. 3 is another structural representation of the present utility model.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands this utility model further, and do not form the restriction to its right.
See figures.1.and.2, a kind of venous detaining needle needle assembly, comprise casing seat and rustless steel puncture needle, described rustless steel puncture needle comprises solid needle body 4 and needle handle, casing seat front end is provided with the indwelling flexible pipe 3 wrapping up solid needle body 4, the needle tip of solid needle body 4 is provided with blood back hand-hole 1, and the solid needle body 4 be in indwelling flexible pipe 3 is provided with blood back and portals 5, be provided with in solid needle body 4 be communicated with blood back hand-hole 1 and blood back portal 5 blood back passage 2.The front end of described solid needle body 4 is cone shape, and described blood back hand-hole 1 is located on the taper seat of aforementioned cone 6.
When blood back hand-hole 1 and blood back portal 5 only have one respectively time, its relation is as follows: blood back hand-hole 1 and blood back portal and 5 can be arranged on solid needle body 4 by homonymy, and when homonymy is arranged, blood back passage 2 is in the side of solid needle body 4.Also can blood back hand-hole 1 and blood back to portal 5 both sides being symmetricly set on solid needle body 4, when both sides are arranged, blood back passage 2 is solid needle body 4 athwart.
With reference to figure 3, when blood back hand-hole 1 and blood back portal 5 have two respectively time, its relation is as follows: described blood back hand-hole 1 comprises the first blood back hand-hole 11 and the second blood back hand-hole 12, blood back portal 5 comprise the first blood back portal 51 and second blood back portal 52, blood back passage 2 comprises the first blood back passage 21 and the second blood back passage 22, first blood back hand-hole 11 and the first blood back portal 51, second blood back hand-hole 12 and the second blood back 52 branch's homonymies that portal are arranged on solid needle body 4, first blood back hand-hole 11 and the first blood back are portalled and 51 to be connected by the first blood back passage 21, second blood back hand-hole 12 and the second blood back are portalled and 52 to be connected by the second blood back passage 22.
