Description
Technical field
The utility model belongs to technical field of medical equipment production equipment, is related to a kind of attitude reference device, especially a kind of needle
The attitude reference device of pipe blade surface.
Background technique
In medical device industry, medical needle applications are very extensive, such as remaining needle, intravenous needle.It is used at present medical
Needle is made of needle tubing, needle stand piece etc..By taking intravenous needle as an example, there is the blade surface of puncture at the tip of needle tubing, in use, hand-held solid
It is scheduled on the needle stand piece of needle tubing tail end, so that needle tubing tip is close to human skin, when being punctured, hand clutches needle stand piece, needle tip
Tiltedly upward, skin vein blood vessel is close at the cutting edge position of needle point blade surface, can just be conducive to puncture, if tip portion sword for point blade surface
Face tiltedly downward, then is difficult to be punctured.Therefore, the cutting edge at needle tubing tip and needle stand piece must be allowed to keep special when making medical needle
Angle is determined so that it is convenient to which medical staff punctures.
At present, it is common to use Dispoable medical needle assembling in, man-made assembly still accounts for significant proportion, that is, uses
Manual mode of operation fits together medical needle tubing with syringe；Part company uses semi-automatic or automation equipment
Medical needle assembling is carried out, still, the orientation problem of medical needle tubing is never fully solved, in this way, if medical needle tubing
Length and the positioning of blade surface angle are inaccurate, and it will cause the difference of the length and angle of same a batch of medical needle after assembling, nothings
Method really realizes the automatic assembly operation of medical needle, and the length of the medical needle after assembling and the consistency of angle are poor, cause huge
Big waste.
