Abstract
The utility model relates to the field of medical equipment, particularly to a deep vein puncture needle. The deep vein puncture needle comprises a puncture needle body which is a long and thin needle bar, the latter half portion of the needle bar is bent into a puncture needle circle portion, the extending portion of the left side end of the puncture needle circle portion is the puncture needle front end portion, and the right side end of the puncture needle circle portion is the puncture needle tail end. According to the deep vein puncture needle, the long and thin puncture needle body is adopted, the latter half portion of the puncture needle body is bent into a circle, the puncture needle front end portion and the puncture needle back end are enabled to be on the same horizontal force line, and the puncture needle back end is connected with an injector port; a guide wire is replaced with the puncture needle, and the puncture needle has the advantages that the puncture time is saved, risks of puncture failures and blood vessel injury are reduced and the like.
Description
Technical field
This utility model relates to medical instruments field, is 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 be widely used in clinical position, is to utilize a kind of puncture needle guiding that a kind of special venous duct is put and stayed in dark vein (femoral vein, subclavian vein, internal jugular vein etc.) intracavity through the skin puncture.Through this venous duct, can infuse and the measuring center venous pressure.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 first to penetrate 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 insert venous duct along seal wire, finally extract the guiding seal wire.Traditional deep venous puncture art step complexity, in inserting the process that guides seal wire and insert venous duct along the guiding seal wire, be difficult for fixing, easily cause guiding seal wire or venous duct injured blood vessel wall and skid off outside blood vessel, in the actual clinical operation, operator's puncture failure rate and patient's potential safety hazard have been increased undoubtedly.
The utility model content
The purpose of this utility model is for the defect of prior art and deficiency, 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 to a circle, and make 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 adopted in the utility model is:
A kind of deep vein puncture needle described in the utility model, 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, this utility model beneficial effect is: a kind of deep vein puncture needle described in the utility model, it adopts an elongated puncture needle, the latter half of this puncture needle is bent to form to a circle, and make 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 accompanying drawing explanation
Accompanying drawing described herein is to be used to provide further understanding of the present utility model, forms the application's a part, but does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
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;
22, tail end of conduit; 3, syringe.
The specific embodiment
Describe this utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples wherein and explanation only are used for explaining this utility model, but not as to restriction of the present utility model.
As shown in Figure 1, the described a kind of deep vein puncture needle of this concrete enforcement, 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 this utility model, 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 after plasticity is processed, 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.
This utility model is when concrete the use, venous duct 2 is located on the right side of puncture needle circle part 12 in 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, start 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 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 puncture needle and guiding seal wire as traditional puncture, has saved the puncture time, has reduced the risk of puncture failure and injured blood vessel.
A kind of deep vein puncture needle described in the utility model, it adopts an elongated puncture needle, the latter half of this puncture needle is bent to form to a circle, and makes 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 is only better embodiment of the present utility model, and the equivalence of doing according to the described structure of this utility model patent claim, feature and principle therefore all changes or modifies, and is included in this utility model patent claim.
