Abstract
The invention discloses an anti-thrombosis remaining needle device. The anti-thrombosis remaining needle device includes a remaining needle main body provided with a three-way connection structure; one interface of the three-way connection structure is communicated with a remaining needle head, and one interface of the three-way connection structure is communicated with an infusion device; an anti-thrombosis structure is communicated with the remain interface of the three-way connection structure; the infusion device is communicated with the remaining needle main body during infusion, a water stopping clamp on the infusion device is opened, liquid is injected into the remaining needle main body and is injected into a sleeve of the anti-thrombosis structure via the three-way connection structure, and the sleeve is filled with the liquid; after the infusion is completed, the infusion device is moved away, the interface of the three-way connection structure in butt joint with the infusion device are processed, an external force acts on a bias assembly to allow the bias assembly to generate the partial pressure for pushing a piston to slide toward the three-way connection structure, and the piston slowly slides toward a communicated position between the sleeve and the three-way connection structure under the action of the partial pressure, so that the liquid in the sleeve is slowly pushed into the remaining needle device until the partial pressure disappears, and blood returning or thrombus in the needle head of the remaining needle device can be prevented.
Description
Technical field
The present invention relates to a kind of venous detaining needle, relate in particular to a kind of preventing thrombosis indwelling needle device that can prevent thrombosis.
Background technology
The use of remaining needle can reduce infant because of venipuncture repeatedly and the misery caused and to the fear of having an injection, alleviate the impatience of the head of a family, be convenient to clinical application, suddenly, the rescue medication of critical patient, alleviate the workload of nurse, reduce infant pain, thus venous detaining needle is in wide clinical application.
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.
Summary of the invention
For this reason, technical problem to be solved by this invention is that in prior art, thrombosis situation easily appears in remaining needle, needs siphunculus, and easily cause potential safety hazard when not only again infusing; And then a kind of preventing thrombosis indwelling needle device that can prevent thrombosis is provided.
For solving the problems of the technologies described above, a kind of preventing thrombosis indwelling needle device of the present invention, it comprises the remaining needle main body being provided with three-port structure, one of them orifice remaining needle syringe needle of described three-port structure, an orifice transfusion device; Also comprise the preventing thrombosis structure with the remaining orifice in described three-port structure, described preventing thrombosis structure comprises
