Description
Technical field
The utility model relates to medical equipment fields, and in particular to a kind of blood taking needle.
Background technique
Medical industry uses at present and the anti-needle of patent database publicity pierces self-destructing safety blood taking needle, primary structure principle
Have a three classes: one kind based on spring or other catapult-launching gears, after blood sampling or pressing ejection part is realized on a patient body
Needle retractable.Its self-destruction and anti-needle thorn function are stronger, wherein pressing retraction type is easy to use and operate, it is ideal type safety blood taking
Needle.But its ejection structure has that component is more, structure is complicated, and as the easy consumptive material of low value, production is related to injection molding, welding and complicated
Assembly, the especially sterilizing of some anomaly sxtructures and packaging is complicated, often cannot achieve standardization and automation processing, therefore
Effect does not protrude in industrial application.It directly launches on a patient body simultaneously, there is blood sample fly bomb and patient caused by vibration
It is uncomfortable.
It is another kind of based on card slot, card closure assembly.Device is fixed on needle stand or is covered on hose when having hose, is taken a blood sample
Card slot is snapped on needle tubing after the completion and realizes anti-needle thorn.This kind of technical pattern is simple, is easy to injection molded and assembly, and uses
Process need to be absorbed in and alignment function when engaging, or even a snap action is increased for user, this and existing blood taking needle
Sheath, which returns drowning, difference substantially, therefore market has no applications well.
There are also one kind based on the push-pull configurations such as sliding block, guide tube and protective cover.By the components such as needle tubing, handle and hose and this
A little device connections, change traditional blood taking needle construction, are moved by sliding block on guide tube to realize that needle tubing enters in protective cover.At present
This kind of Technology design structure is slightly complicated, or even has several groups of sliding blocks or bayonet unit, and implementation process sliding has some setbacks, and user is difficult
To realize singlehanded ease of Use.
In addition existing blood taking needle spininess is to carrying out safeguard procedures after blood sampling, and ignores in blood collection procedure to medical staff
Protection.
