Description
Technical field
This utility model relates to a kind of venous detaining needle, specifically a kind of push-down preventing thrombosis venous detaining needle.
Background technology
Venous detaining needle is easy and simple to handle, is applicable to the puncture at any position, alleviates the misery of patient's repeated localised puncture simultaneously, alleviates the workload of nursing staff, and dark being protected suffers from welcome clinically.But venous detaining needle, in time-out transfusion, and is retained in the process of vein blood vessel, owing to forming thrombosis in blood backflow to flexible pipe, thus blocking infusion channel.In recent years, there is the patented product of many " positive pressure connector " and " counterflow-preventing ", but all the time can not the formation of anti-tampon, after utilizing existing remaining needle to complete transfusion, in order to pre-blockage resisting infusion channel, normal saline washing pipe must be used, complete rear heparin sodium tube sealing, within every 6 to 8 hours, carry out siphunculus again, therefore workload is very large, in addition, when using traditional remaining needle, when carrying out the care program of siphunculus, can a large amount of thrombosis be poured in the blood vessel of human body, produce very serious potential risk, and acute vascular class disease can be produced, there is red and swollen pain in the injection site as patient, injury is brought to patient, there is the defect that quality of medical care is not high, further, above-mentioned care program, need the expense of spending washing pipe liquid, the expense of tube-sealing solution and the expense of labor of nursing, these expenses are well beyond the price of remaining needle itself, therefore medical treatment cost is higher.
Patent Office of the People's Republic of China disclosed on October 2nd, 2013
open (bulletin) number iscN103330970A, patent name is the Patent Application Publication of the thrombosis prevention device of venous detaining needle, and present patent application document relates to the category of medical apparatus and instruments, and be a kind of thrombosis prevention device of venous detaining needle, it is by casing seat, sleeve pipe, piston, ejector sleeve, and nook closing member forms.It is characterized in that there is a piston in casing seat, piston is fixed on the end of ejector sleeve, and nook closing member passes and is enclosed within sleeve pipe in ejector sleeve and from piston.Extract nook closing member after having operated venipuncture routinely just can infuse.During transfusion time-out tube sealing, piston pushes away forward and the blasthole of closed casing.When continuing to infuse, piston is drawn back.Simple to operate and there is malleation and close the effect of dual preventing thrombosis stoping blood backflow.But must grasp the speed and strength promoting piston when the technical scheme of this patent application uses, the speed of propelling is faster, and the effect of preventing thrombosis is poorer, speed limit advances the effect that just can reach design, therefore the effect of preventing thrombosis is unstable in actual applications.
Summary of the invention
The purpose of this utility model overcomes deficiency of the prior art, the spiral push-rod preventing thrombosis venous detaining needle providing a kind of effect of preventing thrombosis more reliable and more stable.
For achieving the above object, the technical scheme that this utility model adopts is:
Spiral push-rod preventing thrombosis venous detaining needle, comprise syringe, indwelling flexible pipe, puncture needle and extension tube, the sidewall of syringe is provided with medicinal liquid input port, one end of syringe is medicinal liquid delivery outlet, indwelling flexible pipe is connected with the medicinal liquid delivery outlet of syringe, one end of described extension tube is connected with medicinal liquid input port, it is characterized in that: also comprise hands handle, push rod and end socket, described end socket is located in syringe, in order to medicinal liquid input port and medicinal liquid delivery outlet are opened or close, one end of push rod is fixedly connected with end socket, the other end is connected with the handle outside syringe, described push rod or handle or end socket, be threaded with the barrel of syringe, the needle point of described puncture needle enters in syringe through handle, push rod and end socket, passes from indwelling flexible pipe through medicinal liquid delivery outlet.
Described push rod or be provided with sealing ring between end socket and the barrel of syringe.
Described extension tube is provided with fixture.
Described fixture is intermediate plate, liquid stopping clamp or actuator.
The other end of described extension tube is connected with transfusion device by calparine cap or positive pressure connector.
The beneficial effects of the utility model:
Owing to adopting above-mentioned version, in the mode of screw propulsion, well limit the speed that end socket advances, therefore the effect of preventing thrombosis is more reliable and more stable;
Alleviate nursery work: after existing remaining needle completes transfusion, normal saline washing pipe must be used, complete rear heparin sodium tube sealing, within every 6 to 8 hours, carry out siphunculus again, therefore workload is very large, this utility model eliminates above-mentioned operation nursing completely after completing transfusion, greatly simplify care program, thus alleviate nursery work;
Improve quality of medical care: thrombosis endangers very large in human body, and each medical personnel understand, when using traditional remaining needle, when carrying out the care program of siphunculus, can a large amount of thrombosis be poured in the blood vessel of human body, produce very serious potential risk.And acute vascular class disease can be produced, there is red and swollen pain in the injection site as patient, so the pot life of pertinent regulations remaining needle is 72 hours, and this utility model has the function of preventing thrombosis, therefore can quality of medical care be improved, avoid when patient is cured, the injury brought.
