Description
Technical field
A kind of medical apparatus is the utility model is related to, in particular for the safety shield of disposable aspiration needle.
Background technology
Existing disposable blood sampling or injection needle are all equipped with cylindrical cavity sheath.The sheath effectively can protect syringe needle to exist
It will not be contaminated before use, will not also cause to accidentally injure.But in general operating process, sheath is abandoned after being removed from syringe needle,
It can not effectively prevent needle point from hurting sb.'s feelings and speckling with again the needle point secondary pollution of patient blood sample；Meanwhile even if not abandoning sheath,
Set is returned on syringe needle again after use, and there is also use the drawbacks of not enough facilitating；And weight after cylindrical cavity sheath is taken a blood sample
The risk that finger is stabbed by needle point also be present in the new operation being enclosed on syringe needle.
Utility model content
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is to provide a kind of for disposably adopting
The safety shield of blood syringe needle, effectively avoid the syringe needle after use from hurting sb.'s feelings and speckle with the needle point secondary pollution of patient blood sample, make
With conveniently.In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is a kind of folding for disposable aspiration needle
Stacked safety shield, including the syringe needle of needle body and shank composition, it is characterised in that sheath is located at syringe needle side, sheath root hinge
It is connected on the shank of syringe needle；Sheath, which is provided with, can accommodate the vallecular cavity of syringe needle, and the opening of the vallecular cavity of sheath is towards syringe needle；The vallecular cavity of sheath
It is interior to be provided with needle body locking mechanism.
The beneficial effects of the utility model are, after syringe needle use, syringe needle need to be only pushed into the vallecular cavity of sheath from side
It is interior, locked by needle body locking mechanism.The syringe needle after use can be effectively avoided to hurt sb.'s feelings and speckle with the needle point two of patient blood sample
Secondary pollution, devoid of risk easy to use.
Preferably, the sheath root is hinged on the shank of syringe needle by elastic joint；The needle body locking mechanism by
Elastic coupler body and the guide ramp composition being set up in parallel；When syringe needle rotation is included in the vallecular cavity of sheath, needle body side passes through elasticity
Crack between coupler body and guide ramp enters the hook portion of the elastic coupler body.
Using said structure, syringe needle enters the convenient locked process of vallecular cavity, needle body, smoothness, without error；Simultaneously as
The rotation trend in opposite direction with actual rotation, the trend that the reverse rotation resets integrally be present in the effect of elastic joint, syringe needle
Limited by the hook portion, so as to which stably syringe needle is locked in vallecular cavity.
Further, guiding locating part is additionally provided with the vallecular cavity, the guiding locating part is arranged at elastic coupler body and guiding is oblique
The front in face；The guiding locating part is provided with diminishing gap structure from top to bottom.
In above-mentioned technical proposal, the front is the needle point direction of pointer body.Its role is to guide needle body to pass through elasticity
Crack between coupler body and guide ramp enters the hook portion of the elastic coupler body；The activity for limiting needle body after entering simultaneously is empty
Between so that locking is more stable.
With improvement, the vallecular cavity is provided with from root to the diminishing neck in free end.The groove for avoiding plastic mould pressing from shaping
The deformation of chamber side wall is chipped, and causes locking to fail.Further, guiding locating part, elastic coupler body and its guide ramp are set
In the neck.
Folding safety sheath of the present utility model can apply to disposable vein blood taking needle, syringe, flexible pipe
Blood taking needle, it is hard connect on the medical apparatus with blood sampling function such as formula blood taking needle, straight blood taking needle, transfusion device, blood gas analysis pipe and
On other medical apparatus.
The utility model is described further below in conjunction with the drawings and specific embodiments.
