Description
Technical field
This utility model relates to a kind of transfusion device, particularly relates to a kind of transfusion device with automatic solution stopping, blood return prevention and filtration.Belong to the armarium technical field.
Background technology
At present, in medicine and hygiene fields, usually adopt disposable infusion set that the patient is carried out venous transfusion.For the utility model patent of " 200920085997.X " a kind of disposable transfusion device safe in utilization is disclosed like Chinese patent number; It comprises dropping funnel, dropper and drain pipe; It is characterized in that: it also comprises gear-like plastics floating plug and flexible latex ring medicated cap; Gear-like plastics (or other material) floating plug is positioned at dropping funnel, and flexible latex ring medicated cap is placed on the mouth of pipe of drain pipe.Be characterized in the dropping funnel of the defeated device of common disposable use, placing gear-like plastics (or other material) floating plug, embedded flexible latex sealing ring medicated cap is when transfusion is nearly accomplished; Floating plug is along with liquid level descends; Under atmospheric pressure and floating plug gravity pressure, embedded flexible latex sealing ring medicated cap blocks the fluid mouth of pipe, makes air can't enter into infusion pipeline; Thereby prevent behind the air admission human vein issuablely, reach the purpose of safe infusion patient's adverse influence.But also there is following shortcoming in this transfusion device: 1, the blood back phenomenon takes place easily, have potential safety hazard, bring doctor-patient dispute for patient and medical personnel.2, do not have filtering function.And transfusion device of the prior art mostly is to adopt the plane to filter, and has that exhaust problem, medicament flow rate are low, the shortcoming of poor stability, causes filter membrane to be stopped up by impurity of the drug easily simultaneously, and medicinal liquid can't be flowed down, and causes needs replacing transfusion device.
The utility model content
The purpose of this utility model is to have the shortcoming that blood back takes place easily and do not possess filtering function in order to solve disposable practical transfusion device of the prior art, and a kind of transfusion device with automatic solution stopping, blood return prevention and secondary filter structure is provided.
The purpose of this utility model can reach through taking following technical scheme:
A kind of transfusion device with automatic solution stopping, blood return prevention and filtration; Comprise funnel and be positioned at the dropper interface and the drain pipe interface of funnel two ends; It is characterized in that: the bottom at the funnel inner chamber is provided with control flume; In control flume, be provided with cylindric floating plug, said cylindric floating plug can move up and down along the inner chamber of control flume; The opening of cylindric floating plug is provided with latex ring medicated cap, and latex ring medicated cap is over against the drain pipe interface, and the internal diameter of latex ring medicated cap is identical with the mouth of pipe external diameter of drain pipe interface; In the drain pipe interface, be provided with the control collodion silk, remain with the gap in the inwall junction of control collodion silk and drain pipe interface.
The purpose of this utility model can also reach through taking following technical scheme:
A kind of embodiment of this utility model is: said control flume is the round barrel shape structure.
A kind of embodiment of this utility model is: said control flume is formed by the manufacturing of polypropylene non-woven fabric film.
The beneficial effect of this utility model:
1, this utility model is established the control collodion silk simultaneously through establish control flume and round barrel shape floating plug in the inside of funnel in drain pipe, and the opening of round barrel shape floating plug is provided with latex ring medicated cap; Medicinal liquid gets into funnel; Driving round barrel shape floating plug moves up along the inner chamber of control flume, up to the top that arrives the control flume inner chamber, at this moment; The mouth of pipe of drain pipe is opened, and liquid normally flows out from drain pipe; When transfusion is accomplished, add in the weight of transfusion device top air pressure and round barrel shape floating plug self under the effect of suction of upper hopper liquid outlet, latex ring medicated cap is with regard to the tight liquid outlet that blocks; Still keep the fraction medicinal liquid in the drain pipe of funnel bottom; Make air can not get into drain pipe, simultaneously, remain with the gap between the control collodion silk in drain pipe and the inwall of drain pipe; Make that fraction medicinal liquid that is retained in funnel bottom and the drain pipe slowly ooze out, to reach the purpose that prevents blood back.
2, the control flume of this utility model is formed by the manufacturing of polypropylene non-woven fabric film; Can filter the impurity in the medicinal liquid more than 5 microns; It is big to have the multi-faceted volume of filter area, and filter interior is big, and medical filtration does not go through under fast, the gas; Filter out the stifled at all incessantly filter membrane of medicinal liquid impurity, the advantage of safe ready.
