Abstract
An expandable injection needle is composed of a plastic needle sleeve and a needle body, and features that an additional geometic hollow tube is connected to the back end of said plastic needle sleeve. Before the injection needle is used, the geometric hollow tube must be shown to the patient and then is broken off.
Description
Affiliated technical field:
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of injection needles of patients injection.
Background technology:
Present all injection needleses, though title injection needles, all has once more or nonexpondable possibility, its weak point can not be stopped cross infection.
Summary of the invention:
The technical problem to be solved in the present invention is: overcome at present used injection needles and use once more or repeatedly.
The objective of the invention is to be achieved through the following technical solutions, injection needles is made up of plastics needle guard, needle point, plastics needle guard rear end at used injection needles connects a geometry hollow cylinder, the geometry hollow cylinder can be truncate hollow cone, hollow cylinder, open circles arc column body etc., the interior diameter of geometry hollow cylinder is identical or a little bigger slightly with plastic-like needle guard rear end diameter, and geometry hollow cylinder and plastic sheath junction fracture easily, divide.
The invention has the beneficial effects as follows:
Injection needles adopts said structure, because the plastics needle guard and the geometry hollow cylinder of injection needles link together, during use, the geometry hollow cylinder must be fractureed, divides in face of patient, otherwise can't use, make patient judge clearly all whether injection needles used, and can't reclaim use like this, thereby can prevent secondary from using entry needle effectively and the viral cross infection that produces.
Description of drawings:
Fig. 1 injection needles sketch map 1---needle point 2---plastics needle guard 3---geometry hollow cylinder (hollow cylinder).4---the junction
Concrete enforcement:
Fig. 1 links together geometry hollow cylinder 3 (hollow cylinder) and plastics needle guard 2 when implementing, junction point frangibility, division, during use, the junction 4 of geometry hollow cylinder 3 (hollow cylinder) and plastics needle guard 2 is fractureed, divides in face of patient, otherwise can't use, make patient can both judge clearly whether this injection needles used, and can't recycle like this, thereby effectively prevent from viral cross infection to take place because of secondary uses entry needle.
Claims (2)
1, a kind of injection needles of forming by plastics needle guard, needle point, it is characterized in that connecting a geometry hollow cylinder in the plastics needle guard rear end of used injection needles, geometry hollow cylinder interior diameter is identical or big slightly with plastics needle guard rear end diameter, junction frangibility, the division of geometry hollow cylinder and plastics needle guard.
2, injection needles according to claim 1 is characterized in that: plastics needle guard rear end connects a geometry hollow cylinder, and the geometry hollow cylinder can be truncate hollow cone, hollow cylinder, open circles arc column body etc.
