Description
Technical field
This utility model belongs to medical instruments field, relates to a kind ofly to clinical patients, carrying out the venous transfusion medical apparatus and instruments, specifically a kind of automatic liquid-stopping dropping funnel.
Technical background
At present, disposable infusion set is the medical apparatus and instruments of commonly using, and it generally comprises bottle plug puncture unit, dropping funnel, flow regulator, liquid medicine filter, venoclysis needle, by transfusion catheter, they is chained together.Medicinal liquid flows into through bottle plug puncture unit,, through the outlet of dropping funnel, flows into transfusion catheter, through liquid medicine filter, venoclysis needle, enters human body.In the clinical transfusion process, the liquid level of need to the person of accompanying and attending to paying close attention to medicinal liquid, otherwise the phenomenon that there will be the infusion bottle inner liquid medicine to be totally lost and in time do not change infusion bottle or extract intravenous infusion syringe, this can cause blood backflow in catheter of transfusion system or liquid level descend too low and cause gas to enter human body causing the adverse consequencess such as aeroembolism.If the patient continues transfusion, need the air-treatment in the pipeline of dropping funnel lower end is fallen, the mode that usually adopts extruding to be wound around conduit is squeezed the air in conduit in the residual titration bucket, perhaps extracts intravenous needle and re-starts bleeding and change intravenous needle and carry out venipuncture again.Above two kinds of methods are all loaded down with trivial details time-consuming, increased medical personnel's labor intensity and patient's mental burden.
For above problem, people are conceived to infusion unit titrimeter is improved, and have produced a series of automatic liquid-stopping transfusion apparatus.But present Perfusion drip funnel adopts buoy to realize the automatic liquid-stopping function more, as Chinese utility model patent ZL201210284440.5 safety automation liquid-controlled open-close valve, Chinese patent application 201210067717.9 transfusion device point dropping funnels, 201310032521.0 1 kinds of automatic liquid-stopping dropping funnels of Chinese patent application and have the transfusion device of this dropping funnel.This transfusion device is to be subjected to the impact of medicinal liquid buoyancy to stop up tube for transfusion by buoy to reach the automatic liquid-stopping effect.The tradition buoy stops the defect that the drop bucket exists and mainly contains: (1) only the liquid effect to be subject to the impact of medicine liquid ingredient and degree of purity larger, impurity, granule are slightly arranged, plastic buoy just can't coincide with tube for transfusion, thereby loses the automatic liquid-stopping function, the formation hidden danger of quality; (2) require very high to the adaptation of buoy accessory and tube for transfusion seam, thereby the production and processing mode to above two accessories requires very harsh, all need a large amount of checkings and control as the control of the precision of mould, raw-material selection, production process, plastic fittings whether producing distortion etc. after sterilizing, the careless slightly product that will directly cause is lost the automatic liquid-stopping function, causes quality problems; (3) buoy is arranged on the dropping funnel below, and after liquid level drops to a certain degree, buoy stops up the dropping funnel liquid outlet, reaches only liquid purpose, and this only liquid mode liquid level can drop to 1/3 even near dropping funnel liquid outlet place under the dropping funnel chamber usually.If need to continue transfusion, need to be with liquid level top Bas Discharged.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of rational in infrastructure, automatic liquid-stopping dropping funnel that only liquid is reliable for effect, processing technique is simple, easy to operate is provided.
The technical solution of the utility model is, a kind of automatic liquid-stopping dropping funnel, comprise dropping funnel lid and dropping funnel body, the dropping funnel lid is arranged on the top of dropping funnel body, described dropping funnel body is comprised of interior dropping funnel, outer dropping funnel, and interior dropping funnel inwall and dropping funnel lid are in conjunction with dropping funnel chamber in forming, and interior dropping funnel top of chamber is combined with steam vent, the dropping funnel on top, interior dropping funnel chamber covers and is provided with the dropping funnel feed tube, and the interior dropping funnel liquid outlet top of interior dropping funnel bottom is provided with only liquid filter membrane; Outer dropping funnel inwall, dropping funnel lid and interior dropping funnel outer wall are in conjunction with forming outer dropping funnel chamber, but outer dropping funnel chamber is combined with the air inlet of folding, and bottom, outer dropping funnel chamber is provided with the dropping funnel liquid outlet.
Described only liquid filter membrane is fixed on the supporting surface of interior dropping funnel bottom by ultrasonic welding process or heat seal process or mechanical process for pressing.
Be provided with the exhaust gas filter film on described steam vent, the exhaust gas filter film is the hydrophobic air filter membrane, is fixed on dropping funnel by ultrasonic welding process or heat seal process or mechanical process for pressing and covers.
The inlet air filtration film is set on described air inlet, and the inlet air filtration film is the hydrophobic air filter membrane, the inlet air filtration film by ultrasonic welding process or heat seal process or mechanical process for pressing fixedly dropping funnel cover.Air inlet is outside equipped with gland, can open, seal air inlet.
The dropping funnel on described dropping funnel body top covers and is provided with liquid injection device.
This utility model adopts membrane material to realize dropping funnel automatic liquid-stopping function, and only the drop bucket structure is simple, reliable for effect, easy to use.When the fast infusion of medicinal liquid is complete, stop under the capillary effect of liquid filter membrane at interior dropping funnel, venous pressure and gravitative pressure active force and filter membrane equalization of strain in the transfusion tube wall, be to make medicinal liquid rest in transfusion device under the comprehensive function power of atmospheric pressure, hydrostatic pressing, human vein, reach the function of automatic liquid-stopping; Continuing transfusion as need can directly insert this transfusion device in new infusion bottle, and the steam vent on interior dropping funnel can be automatically with the air in the transfusion catheter of dropping funnel upper end and the Bas Discharged in interior dropping funnel, thereby realizes the continuous transfusion function after automatic liquid-stopping; After whole transfusions are completed, open the air inlet on outer dropping funnel, outside air can enter outer dropping funnel chamber, and the medicinal liquid in dropping funnel and dropping funnel lower end pipeline is continued to be infused into patient's intravenous, realize the complete infusion of medicinal liquid truly, avoided lessening the curative effect because of liquid waste.
