Abstract
The invention discloses a straight-type vein detaining needle of a multifunctional doser. The vein detaining needle comprises a tubular needle base, a multifunctional doser is arranged on the tubular needle base, the multifunctional doser comprises a drug tube, a piston, a push tube, a division plug and a screw cap, one end of the doser extends into the tubular needle base and is perpendicular to the tubular needle base, corresponding side holes are arranged on the two side walls of the tube wall of the doser, the two side holes and an inner cavity of the tubular needle base are on the same axial line, the other end of the doser is connected with the threads of the screw cap, the piston is arranged on the inner side of the doser, the piston and the screw cap are coupled by the push tube, and the division plug is arranged in the screw cap. Because the vein detaining needle adopts the design of setting the doser in the straight-type structure additionally, the vein detaining needle not only has the advantage of being straight in shape, but also has the advantages of being simple in dosing, anti-clogging and anti-thrombosis and drawing blood readily.
Description
Technical field
The present invention relates to a kind of venous detaining needle, and in particular to a kind of straight type venous indwelling with multi-functional doser
Pin.
Background technology
Existing remaining needle has two kinds of Y types and straight type, and Y types have batcher, operation side also known as enclosed type in the needle stand of Y types
Just, blood will not flow out, and infuse entrance on the side wall of needle stand, and one end of extension tube is connected with transfusion entrance, another
End connecting tee pipe, during transfusion can dosing at any time, but y-type structure is complicated, high cost, and easily blocking forms thrombus.Straight type also known as
Style of opening, as shown in figure 1, transfusion entrance is not located on the side wall of needle stand, but positioned at the end of needle stand, and nothing in needle stand
Batcher, therefore also referred to as style of opening, must be singlehanded during operation, and one hand-lifting pin when pulling out pin, proficiency vascular compression prevents blood from overflowing, but
Dosing is inconvenient, but straight type simple structure, transfusion is smooth, be easy to fixed.Y types and straight type are each advantageous.Their common shortcomings
Produce when being indwelling and block and formed thrombus.So washing pipe is completed when having indwelling to start in the code that operates to remaining needle of various countries
Afterwards, calparine cap tube sealing is used, per 6-8 hours, a siphunculus and tube sealing is carried out, existing various remaining needles has 0.2 to 0.5 milliliter
Liquid Residue.So do not allow using remaining needle blood drawing during indwelling must separately puncture vessel, substantially reduce remaining needle due
Effect.

Further, a diameter of 0.5～1.0mm of the side opening.
Further, the surface of the nut end is provided with puncturing hole.
Further, the aperture of the puncturing hole is 1～2mm.
Further, also including indwelling flexible pipe, the indwelling flexible pipe is connected with one end of tubular needle stand, and the chemical feed pipe is leaned on
One end of nearly indwelling flexible pipe.
Further, also including puncture needle, one end of the puncture needle penetrates from the other end of tubular needle stand, Jing pistons and
Side opening passes through indwelling flexible pipe.
Further, also including blood back room, the blood back room is connected with the other end of tubular needle stand, the other end of puncture needle
Connect with blood back room.
Beneficial effects of the present invention：
Because remaining needle in straight type structure using being additionally arranged doser, therefore not only there is straight type, but also with dosing
The characteristics of facilitating；
When terminating transfusion, the infusion channel of remaining needle is closed, the piston in doser pushes down on generation malleation, inverse with resistant to blood
Stream, exempts from washing pipe, exempts from tube sealing, reaches the effect of anti-clogging preventing thrombosis；
Because doser is located at the porch of indwelling flexible pipe, piston is closed after infusion channel, there is the Liquid Residue of denier in sleeve pipe,
Blood count is not affected, can be drawn blood at any time；
Because puncture needle Jing pistons and side opening pass through indwelling flexible pipe, connect piston after pin and close automatically, prevent hemorrhage.
