Description
Technical field
This utility model relates in the medical field and carries out infusion set quiet, arterial infusion to the patient, refers to a kind of disposable safe transfusion system that can seal infusion pipeline automatically especially.
Background technology
At present, each medical institutions all uses disposable transfusion device when giving patient infusion, and so namely convenient can effectively warding off disease again infected mutually.But this disposable transfusion device has its weak point, carry the pressure to seal infusion pipeline automatically when being about to finish and to make tube for transfusion less than endovascular pressure at medicinal liquid, cause blood samples of patients to be poured into and cause blood coagulation in the tube for transfusion, if this moment, the medical worker did not note slightly, also may be with in a large amount of air input patient bodies, cause sufferer thrombosis or air embolism, threat to life.
At the deficiency of above-mentioned transfusion device, also some solution at present.China Patent No. for example: 200580030194.9 disclosed " disposable safe transfusion systems ", it increases a release mechanism at general infusion set, wherein this release mechanism comprises a housing and a buoyancy aid that is positioned at housing, below buoyancy aid, be provided with a seal membrane and a concave shaped portion, the one-body molded common formation driving fit part of seal membrane and concave shaped portion, buoyancy aid lifting along with the increase and decrease of housing inner liquid medicine, thus realize the sealing of housing medicine liquid outlet portion, stop in the air admission tube for transfusion.
Though above-mentioned invention can realize the automatic airtight of infusion pipeline, but when the transfusion beginning, because the come-up of buoyancy aid has hindered the dirty of medicinal liquid, cause the pressure in the following tube for transfusion of buoyancy aid to reduce greatly, simultaneously it closes to an end and during the closed transfusion pipeline in transfusion, remain in the interior amount of liquid medicine of tube for transfusion seldom, also cause the pressure in the tube for transfusion to reduce greatly, so when the patient who gives the high vein of tremulous pulse or vascular pressure infuses beginning and general patient infuse when finishing, endovascular blood tends to anti-the inflow in the tube for transfusion, even anti-the inflow in the medicine bottle, cause tube for transfusion or medicine bottle intravascular coagulation, may jeopardize patient's life.Its structure is complicated simultaneously, and production cost is also higher.
Summary of the invention
The purpose of this utility model is: this utility model provides a kind of disposable self-closing safe transfusion system, energy automatic airtight infusion pipeline when transfusion nearly finishes, do not reduce simultaneously the pressure in the tube for transfusion, blood reflux in the artery and vein is flowed in tube for transfusion and/or the infusion bottle, really reach the transfusion purpose of safety.
Technical scheme provided by the utility model is: a kind of disposable self-closing safe transfusion system, comprise needle for inserting bottle, drip tube, infusion tube, transfusion needle, chemical feed pipe and breather, wherein outside infusion tube, be equipped with the flow regulator for the control fluid flow, in dripping tube and/or between infusion tube and the tube, a self-closing assembly of safety is set at least, the self-closing assembly of described safety comprises appearance liquid, drain body and airtight film body, it is characterized in that, described drain body has the passage for the medicinal liquid circulation, the top of this drain body is airtight, the side of this drain body arranges an opening at least, described airtight film body is installed with at drain external, this airtight film body top is provided with funnel parts and connects as one with described appearance liquid, described appearance liquid arranges a medicine liquid outlet portion at least, and described drain body is connected with infusion tube by this export department.Wherein said airtight film body is arranged to the unidirectional flap valve of described drain body airtight, open airtight film body with the gravity of medicinal liquid self, described airtight film body is arranged to all openings of described drain side side airtight, makes that airtight film body can the automatic airtight infusion pipeline when transfusion finishes.Described airtight film body and described drain body connect as one, and make medicinal liquid to flow into the infusion tube from the opening of drain side side.Described airtight film body is made of elastomeric material at the opening part of airtight drain side side at least.Described drain body and described appearance liquid connect as one, and make the drain body to be fixed on and hold on the liquid.Described appearance liquid and described tube split setting also connect as one or one-body molded setting, make medicinal liquid to flow into from drip tube and hold in the liquid, thereby open airtight film body.
The beneficial effects of the utility model are: a kind of disposable self-closing safe transfusion system, energy automatic airtight infusion pipeline when transfusion nearly finishes, prevent in the air admission patient body, and no matter in the transfusion beginning, still do not reduce pressure in the tube for transfusion nearly when finishing in transfusion, blood reflux in the artery and vein is flowed in tube for transfusion and/or the infusion bottle, and it is simple in structure, easy and simple to handle.
