Abstract
The invention relates to the field of medical instruments, in particular to a deep venipuncture needle which comprises a puncture needle body, wherein the puncture needle body is a slender needle bar; the rear half of the needle bar is bent into a puncture needle circle part; the extension part at the left side end of the puncture needle circle part serves as a puncture needle front end part; the right side end of the puncture needle circle part serves as a puncture needle tail end. The slender needle bar is adopted, the rear half of the needle bar is bent into a circle, the puncture needle front end part and the puncture needle tail end are on the same horizontal line, and a syringe interface is connected to the puncture needle tail end. A guiding conducting wire is replaced by the puncture needle body, so that puncture time is reduced, and hazards of puncture failure and vessel damage are reduced.
Description
Technical field
The present invention relates to medical instruments field, be specifically related to a kind of deep vein puncture needle.
Background technology
The deep venous puncture art is a kind of operation of diagnosis and treatment that is widely used in the clinical position, is to utilize a kind of puncture needle guiding that a kind of special venous duct is put through the skin puncture to stay in dark vein (femoral vein, subclavian vein, internal jugular vein etc.) intracavity.Can infuse and the measuring center venous pressure through this venous duct.Dark Vein Tube has the advantages such as retention time is long, transfusion speed is fast, the transfusion kind is extensive, nursing is convenient.
Traditional deep venous puncture art need to utilize thick puncture needle to penetrate first vein, through inserting the guiding seal wire in the tube chamber of this thick puncture needle, then extracts thick puncture needle, and fixedly seal wire and insert venous duct along seal wire is extracted the guiding seal wire at last.Traditional deep venous puncture art step is complicated, inserting the guiding seal wire and be difficult in the process of venous duct fixing along guiding seal wire to insert, easily cause guiding seal wire or venous duct injured blood vessel wall and skid off outside the blood vessel, in the actual clinical operation, operator's puncture failure rate and patient's potential safety hazard have been increased undoubtedly.
Summary of the invention
The object of the invention is to defective and deficiency for prior art, provide a kind of simple in structure, a kind of deep vein puncture needle reasonable in design, easy to use, it adopts an elongated puncture needle, the latter half of this puncture needle is bent to form a circle, and so that puncture needle fore-end and puncture needle rear end on the same level line of force, and this puncture needle rear end connects a syringe interface; It uses this puncture needle to replace the guiding seal wire, has and has saved the puncture time, has reduced the advantages such as risk of puncture failure and injured blood vessel.
For achieving the above object, the technical solution used in the present invention is:
A kind of deep vein puncture needle of the present invention, it comprises the puncture needle body, described puncture needle body is an elongated shank, the shank latter half is bent to a puncture needle circle part, this puncture needle circle part left-hand end extension is the puncture needle fore-end, and this termination, puncture needle circle part right side is the puncture needle tail end.
Further, described puncture needle tail end is connected with syringe interface.
After adopting said structure, beneficial effect of the present invention is: a kind of deep vein puncture needle of the present invention, it adopts an elongated puncture needle, the latter half of this puncture needle is bent to form a circle, and so that puncture needle fore-end and puncture needle rear end on the same level line of force, and this puncture needle rear end connects a syringe interface; It uses this puncture needle to replace the guiding seal wire, has and has saved the puncture time, has reduced the advantages such as risk of puncture failure and injured blood vessel.
Description of drawings
Accompanying drawing described herein is to be used to provide a further understanding of the present invention, consists of the application's a part, but does not consist of to improper restriction of the present invention, in the accompanying drawings:
Fig. 1 is structural representation of the present invention.
Description of reference numerals:
1, puncture needle body; 11, puncture needle fore-end; 12, puncture needle circle part;
13, puncture needle tail end; 14, syringe interface; 2, venous duct; 21, conduit head end;

The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation only are used for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 1, the described a kind of deep vein puncture needle of this implementation, it comprises puncture needle body 1, described puncture needle body 1 is an elongated shank, the shank latter half is bent to a puncture needle circle part 12, these puncture needle circle part 12 left-hand end extensions are puncture needle fore-end 11, and this termination, puncture needle circle part right side is puncture needle tail end 13.
Described puncture needle tail end 13 is connected with syringe interface 14.
It has removed the guiding seal wire of traditional deep venous puncture art in the background technology the present invention, it adopts an elongated puncture needle, this puncture needle has certain hardness, not yielding, it is puncture needle circle part 12 that the latter half of this puncture needle is bent to form a circle, and require through after the plasticity processing, the puncture needle fore-end 11 of puncture needle circle part 12 rear and front ends is consistent with the line of force of puncture needle tail end 13; Puncture needle shank tail end 13 has syringe interface 14, and this syringe interface 14 can connect syringe 3, and this sample puncture needle body 1 just can replace the guiding seal wire.
The present invention is when concrete the use, venous duct 2 is located on the right side of puncture needle circle part 12 in the puncture needle body 1, the tail end of conduit 22 of this venous duct 2 is located in puncture needle circle part 12 tops, and the conduit head end 21 of this venous duct 2 is located in the afterbody of puncture needle fore-end 11; Use syringe interface 14 to connect syringe 4, begin to carry out deep vein puncture, after the puncture needle fore-end 11 of elongated puncture needle body 1 penetrates blood vessel, but syringe 3 pumpbacks go out blood, fixedly the puncture needle body 1, venous duct 2 is inserted in the blood vessel along puncture needle body 1, extract puncture needle body 1 and get final product.Whole piercing process accomplishs without any letup, and no longer needs to change as traditional puncture puncture needle and guiding seal wire, has saved the puncture time, has reduced the risk of puncture failure and injured blood vessel.
A kind of deep vein puncture needle of the present invention, it adopts an elongated puncture needle, the latter half of this puncture needle is bent to form a circle, and so that puncture needle fore-end and puncture needle rear end on the same level line of force, and this puncture needle rear end connects a syringe interface; It uses this puncture needle to replace the guiding seal wire, has and has saved the puncture time, has reduced the advantages such as risk of puncture failure and injured blood vessel.
The above only is better embodiment of the present invention, therefore all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
