Description
Technical field
The present invention relates to a kind of venous detaining needle, specifically a kind of method of preventing thrombosis venous detaining needle and preventing thrombosis thereof.
Background technology
Existing remaining needle is divided into Y type and straight type, and because Y type is convenient, China generally uses the remaining needle of Y type; And the remaining needle troublesome poeration of straight type, but thrombosed probability is lower than the remaining needle of Y type, generally uses the remaining needle of straight type abroad.
Traditional remaining needle, during indwelling, all may produce thrombosis, all specifies in relevant operational code for this reason, every 6 to 8 hours with normal saline washing pipe once, and use anticoagulant tube sealing.
For solving above-mentioned deficiency, there is the patented product of positive pressure connector and anti-backflow device in recent years, but existing positive pressure connector and anti-backflow device complex structure, and be all the action utilizing spring to complete extruding liquid instantaneously, therefore the maintenance of the time of barotropic state is not long.
In addition, Patent Office of the People's Republic of China disclosed on October 2nd, 2013
open (bulletin) number iscN103330970A, patent name is the patent of self-styled preventing thrombosis venous detaining needle and using method thereof, the invention discloses a kind of self-styled preventing thrombosis venous detaining needle and using method thereof, this self-styled preventing thrombosis venous detaining needle comprises needle stand, be arranged on the conduit of needle stand front end and the puncture needle core axially across described needle stand and conduit, the inner chamber of described needle stand is cut off part and is divided into plemum and transfusing chamber two parts, described transfusing chamber is communicated with described conduit, and described obstruct section adopts medical encapsulant; Described obstruct section is provided with seepage channel, and for when described plemum and transfusing chamber exist pressure differential, the liquid in described plemum can flow into described transfusing chamber through described seepage channel automatic slowly.Self-styled preventing thrombosis venous detaining needle of the present invention and using method thereof have following Advantageous Effects; Routinely during operation suspension transfusion, automatic pipe sealing, the liquid in plemum slowly flows into transfusing chamber by described seepage channel; Along with the pressure reduction between plemum and transfusing chamber reduces, percolation flow velocity also can slow down thereupon, makes described plemum can maintain malleation for a long time.This Patent Application Publication, be that the applicant researches and develops, although have the function of preventing thrombosis, this Patent Application Publication (also comprising existing all remaining needles) maximum deficiency is, because medicinal liquid all can flow through the cavity of needle stand, therefore remaining needle can not be utilized to draw blood to patient.
This patent is the improvement carried out straight type remaining needle.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of pressure-fired remaining needle is provided, utilize this pin can not only preventing thrombosis, can also draw blood to patient.
Another object of the present invention is a kind of method also providing pressure-fired remaining needle to produce pressure-fired preventing thrombosis.
For achieving the above object, the technical solution adopted in the present invention is:
Pressure-fired remaining needle, comprise indwelling needle, indwelling flexible pipe, puncture needle and transfusion needle, one end of indwelling needle is provided with medicinal liquid delivery outlet, indwelling flexible pipe is connected with the medicinal liquid delivery outlet of indwelling needle, the other end of indwelling needle be puncture needle and transfusion needle penetrate end, described puncture needle, penetrate in indwelling needle in order to the end that penetrates from indwelling needle, pass from indwelling flexible pipe through medicinal liquid delivery outlet, attached retention is put flexible pipe and is penetrated vein blood vessel, be provided with closing cock in described indwelling needle, one end of described closing cock is close to medicinal liquid equipped at outlet port and is closed by medicinal liquid delivery outlet.
Further, described closing cock adopts resilient soft closing cock.
Further, the other end of described closing cock and indwelling needle penetrate hold level with both hands neat.Be designed with the end helped closing cock like this to sterilize.
Further, one end of described puncture needle is provided with handle, and the end of described handle is provided with and indwelling needle can be penetrated the block held and encase.
Pressure-fired remaining needle produces the method for pressure-fired preventing thrombosis, comprises the following steps: after A, the indwelling to vein blood vessel of indwelling flexible pipe, penetrates in indwelling needle, communicate transfusion needle through closing cock with indwelling flexible pipe from the end that penetrates of indwelling needle, starts transfusion; When B, stopping infusion, first transfusion needle is slowly extracted from indwelling needle, in the process of extracting, under the effect of the frictional force between transfusion needle and closing cock, the end face being positioned at the closing cock of medicinal liquid equipped at outlet port forms a concave surface, now, transfusion needle also communicates with indwelling flexible pipe, and to indwelling flexible pipe conveying medicinal liquid; The concave surface of the end face of C, closing cock resets, and makes to produce pressure-fired in indwelling flexible pipe, stops blood backflow in indwelling flexible pipe, thus avoids the formation of thrombosis in indwelling flexible pipe.
Beneficial effect of the present invention:
Owing to adopting above-mentioned version, set up closing cock, closing cock is utilized to be sealed by medicinal liquid delivery outlet, during input medicinal liquid, medicinal liquid directly enters indwelling flexible pipe by transfusion needle, and no longer enters the cavity of indwelling needle, airtight transfusion cavity is reduced greatly, effectively reduce the backflow of blood, not only help avoid the formation of thrombosis in indwelling flexible pipe, but also remaining needle can be utilized to draw blood to patient;
Owing to adopting resilient soft closing cock, transfusion needle is in withdrawal process, the end face of closing cock forms concave surface, and transfusion needle is after extracting, and concave surface resets, make to produce pressure-fired in indwelling flexible pipe, stop blood backflow in indwelling flexible pipe, thus avoid the formation of thrombosis in indwelling flexible pipe, thus alleviate nursery work, improve quality of medical care, save medical treatment cost.
