Description
Technical field
This utility model belongs to medical instruments field, specifically, relates to a kind of adjustable Intravenous Indwelling Needle.
Background technology
At present, in carrying out fluid infusion, all need to use remaining needle.The principle of remaining needle is all that cover has one very thin to think the trocar sheath that puncture needle is the same on remaining needle nook closing member, and trocar sheath is along with remaining needle thrusts in blood vessel together, and trocar sheath is retained in blood vessel like this, and remaining needle nook closing member exits.Above-mentioned design can be carried out repetitious drug administration by injection with remaining needle to patient at any time, safe and convenient.
But remaining needle in being retained in blood vessel for a long time time, there will be indwelling loosening, and the movement of remaining needle, in the time that regulating, above-mentioned remaining needle all need to be extracted by needs, and re-start and thrust in blood vessel, so both waste a large amount of manpower and materials, also caused patient's pain repeatedly.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned defect, a kind of adjustable Intravenous Indwelling Needle is provided, can utilize annular air-pocket and coniform shell adjusting position, realize the change in location that regulates remaining needle, patient is carried out to repetitious drug administration by injection, safe and convenient, can not increase the extra pain of patient and the waste of avoiding manpower and materials.
For addressing the above problem, the technical scheme that this utility model adopts is:
A kind of adjustable Intravenous Indwelling Needle, comprise remaining needle body, remaining needle Connection Block, transfusion sebific duct, puncture needle needle body and puncture needle Connection Block, described remaining needle body, remaining needle Connection Block, transfusion sebific duct are the structure linking into an integrated entity, described puncture needle needle body and puncture needle Connection Block are the structure linking into an integrated entity, and it is characterized in that: the outboard end of described puncture needle Connection Block is provided with syndeton; Described remaining needle body has the cavity adapting with puncture needle needle body, and on cavity, is provided with conical retaining mechanism; The end of described remaining needle body is provided with spreading mechanism.
As a kind of technical scheme of optimization, described remaining needle Connection Block comprises the obstruction in straight-through seat, conical locking mechanism and straight-through seat; Described conical locking mechanism comprises the conical rotational shell that is movably arranged on straight-through seat end, and the diameter of the osculum end of conical rotational shell is not more than puncture needle needle body, and conical rotational shell is threaded on straight-through seat.
As a kind of technical scheme of optimization, described spreading mechanism comprises the annular air-pocket that is arranged on remaining needle body end, and annular air-pocket is by pipeline connection external air source.
As a kind of technical scheme of optimization, described spreading mechanism comprises the fastener that is arranged on puncture needle Connection Block outboard end by connecting axle, and fastener matches with straight-through seat.
Owing to having adopted technique scheme, compared with prior art, this utility model can utilize annular air-pocket and coniform shell adjusting position, realize the change in location that regulates remaining needle, patient is carried out to repetitious drug administration by injection, safe and convenient, can not increase the extra pain of patient and the waste of avoiding manpower and materials.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Detailed description of the invention
Embodiment:
