Description
Technical field
This utility model relates to a kind of sting device used when putting pipe for artery and vein puncture, and the diacan of specifically a kind of improvement, belongs to medical apparatus and instruments technical field.
Background technology
In clinical treatment, artery and vein puncture technology is widely used in clinical transfusion, vital sign monitoring and hemodialysis.Existing diacan mainly comprises nook closing member and sheath cover, during use, is enclosed within nook closing member by sheath cover, first with nook closing member puncture, push sheath along nook closing member again and overlap and sheath cover is fixed puncture successfully, then exit nook closing member, conduit is inserted via sheath cover, finally exits sheath cover, complete operation.But the sheath Analysis of Nested Design on existing diacan is shorter, sheath cover front end too rearward, after nook closing member intravasation, sheath cover is also outside blood vessel, is difficult to accurately judge whether sheath cover inserts Ink vessel transfusing, locates unintelligible, put pipe difficulty, easily cause puncture failure, the operating time so not only can be made long, higher to the requirement of operator, but also injury of human and Principle of Pain can be increased, easily cause conflict between doctors and patients.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of diacan of improvement, its structure is simple, accurate positioning, high, simple to operate quick, the low cost of manufacture little to injury of human of puncture success rate.
Technical scheme according to this utility model provides: the diacan of improvement, comprises nook closing member and sheath cover, and described sheath cover is enclosed within nook closing member and also can moves axially along nook closing member; Described nook closing member afterbody is provided with needle stand, and described sheath cover afterbody is provided with sheath seat, and sheath seat is connected on needle stand; It is characterized in that: described nook closing member is anterior to be stretched out in sheath cover, nook closing member is 0.5 ~ 2mm from the length of extension in sheath cover.
As further improvement of the utility model, described nook closing member is 1mm from the length of extension in sheath cover.
As further improvement of the utility model, described nook closing member tip is set to oblique section, and the tip of described sheath cover is also set to oblique section, and the most advanced and sophisticated oblique section of sheath cover is parallel with the most advanced and sophisticated oblique section of nook closing member.
compared with prior art, advantage is this utility model:
(1), simple, the accurate positioning of this utility model structure, puncture success rate be high, and through clinical experiment, disposable puncture success rate reaches more than 90%.
(2), this utility model is simple to operate fast, little to injury of human, and situation about developing complications is extremely low.
(3), this utility model low cost of manufacture, be convenient to promote the use of on a large scale.

Fig. 2 is the A portion amplification view in Fig. 1.
Description of reference numerals: 1-nook closing member, 2-sheath cover, 3-needle stand, 4-sheath seat.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1 and Figure 2, the diacan of the improvement in embodiment mainly overlaps 2 by nook closing member 1 and sheath and forms, and described sheath cover 2 is enclosed within nook closing member 1 and also can moves axially along nook closing member 1; Described nook closing member 1 afterbody is provided with needle stand 3, and described sheath overlaps 2 afterbodys and is provided with sheath seat 4, and sheath seat 4 is connected on needle stand 3; Described nook closing member 1 front portion is stretched out in sheath cover 2, and nook closing member 1 is 1mm from the length L of extension in sheath cover 2.
In actual production manufactures, different according to purposes, diacan 1 has different specifications and models, and in different size model, nook closing member 1 is also different from the length L of extension in sheath cover 2, generally should be 0.5 ~ 2mm.
As shown in Figure 1 and Figure 2, described nook closing member 1 tip is set to oblique section, this oblique section can make puncture procedure easier, reduce the wound to health, the tip of described sheath cover 2 is also set to oblique section, and the most advanced and sophisticated oblique section of sheath cover 2 is parallel with the most advanced and sophisticated oblique section of nook closing member 1, such sheath overlaps 2 front ends can also play guiding function, facilitate sheath to overlap 2 and enter arteriovenous along nook closing member 1, make sheath overlap the push operation of 2 more easily, reduce the wound that tissue is produced.
During concrete use, be enclosed within nook closing member 1 by sheath cover 2, the needle stand 3 of nook closing member 1 afterbody connects syringe, and the sheath seat 4 that sheath overlaps 2 afterbodys is connected on needle stand 3.First puncture with nook closing member 1, if syringe pumpback has blood back, then illustrate and puncture successfully, judge nook closing member 1 target approach blood vessel.Close on very much with nook closing member 1 tip because the sheath cover 2 in this utility model is most advanced and sophisticated, when after nook closing member 1 target approach blood vessel, sheath cover 2 also just synchronously enters target blood, without the need to promoting sheath cover 2 along nook closing member 1 again as in the past, only sheath need be overlapped 2 to fix, exit nook closing member 1 again can carry out putting pipe operation, put pipe and complete backed off after random sheath cover 2, namely complete whole puncture procedure.
