Description
Technical field
This utility model belongs to medical instruments field, relates in particular to a kind of automatic vent accurate filter.
Background technology
As time goes on, the mankind are constantly developing newtype drug, but the resistance of the threat mankind's formation various diseases is also in continuous increase, virus is also in continuous variation simultaneously, increase difficulty to human treatment's various diseases, the disease that can treat of often taking medicine in the past now needs intramuscular injection or transfusion could treat, and therefore venous transfusion has become modern clinic the most common and one of the most effective administering mode in treating.In the time operating to patient infusion, often can run into the situation that has air in transfusion device, if the not factor such as emptying or rubber pipe device imprecision of transfusion inner air tube, air enters patient blood can form pulmonary embolisms, when tolerance is larger, can jeopardize patients ' lives, therefore, air in tube for transfusion needs to get rid of, the processing method that traditional low side transfusion device runs into this kind of situation is: 1, can first close liquid road, then the silica gel tube outer wall of continuous attack air upper end, makes shift-in on inner air tube to not luxuriant and rich with fragrance dropper place, continue to move down subsequently attack again; 2, adopt lower blind enema, i.e. separating head sword-shaped needle, air is discharged from transfusion device end, then connect scalp acupuncture, but this method is easily polluted joint; 3, upper row's winding method, close liquid road, from alveolate certain section of tube for transfusion below, approximately 20～30cm is starting point, pinch flat tube for transfusion upwards when sliding carrying with hand thumb and forefinger, be tightly wrapped on left index finger pinching flat tube for transfusion, to liquid level Da Mofei dropper, unclamp the right hand, push not luxuriant and rich with fragrance dropper and make 1/2～2/3 of liquid level Da Mofei dropper, then the tube for transfusion that is wound around left hand is slowly unclamped, check in pipe without extremely required number of regulator solution road after bubble; Above method had both bothered also easily withdrawal of needle to beat for the second time again, brought secondary damage to patient.In order to overcome above-mentioned defect, the invention provides a kind of automatic vent accurate filter, after this filter is arranged on the flat dropping funnel of disposable general infusion set, make medicinal liquid when this transfusion device by disposable the gas in medicinal liquid removal, make no longer to contain air in tube for transfusion, solved easily this clinical difficult problem.
Summary of the invention
The main technical problems to be solved in the utility model is to provide a kind of automatic vent accurate filter, after this automatic vent accurate filter is arranged on the flat dropping funnel of disposable general infusion set, can be by disposable the gas in tube for transfusion removal, the deficiencies in the prior art are overcome, provide a kind of simple in structure, easy to operate, safety and sanitation, aerofluxus stable, fast, and be easy to the automatic vent accurate filter of promoting.
This utility model is that the technical scheme adopting is:
A kind of automatic vent accurate filter, comprise: medicinal liquid import 1, ventilated membrane 2, air-vent 3, liquid medicine filtering membrane 4, automatic vent accurate filter shell 5, medicine liquid outlet 6, it is characterized in that: automatic vent accurate filter is a thin column, ventilated membrane 2 covers air-vent 3, air-vent 3 and the external world communicate, be positioned at medicinal liquid import 1 place, top of automatic vent accurate filter circular end surface, liquid medicine filtering membrane 4 is circular, the shell 6 of its edge and automatic vent accurate filter is closely connected, and the inner cylinder body space of automatic vent accurate filter is divided into two, a part is connected with medicinal liquid import 1, another part is connected with medicine liquid outlet 6.
Further technical scheme of the present utility model is:
Described automatic vent accurate filter shell is made taking acrylonitritrile-styrene resin as raw material.
Described liquid medicine filtering membrane is nucleopore membranes or microporous filter membrane.
Described ventilated membrane is poly tetrafluoroethylene.
The beneficial effects of the utility model are: a kind of automatic vent accurate filter is provided, this automatic vent accurate filter has automatic vent mechanism and liquid medicine filtering membrane, solve the disadvantage that current disposable transfusion device can not be got rid of the gas in medicinal liquid, and simple in structure, easy to operate, safety and sanitation, aerofluxus is stable, fast, transfusion device is had and regulate a speed accurately directly perceived, safe and reliable advantage, to ensureing that ten million common people's medical treatment & health has positive role, can be made into series of products, to adapt to chemotherapy, infant, critical patient, SARS, lazaretto ward uses, certainly be also applicable to common patient.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
1. an automatic vent accurate filter, comprise: medicinal liquid import 1, ventilated membrane 2, air-vent 3, liquid medicine filtering membrane 4, automatic vent accurate filter shell 5, medicine liquid outlet 6, it is characterized in that: automatic vent accurate filter is a thin column, ventilated membrane 2 covers air-vent 3, air-vent 3 and the external world communicate, be positioned at medicinal liquid import 1 place, top of automatic vent accurate filter circular end surface, liquid medicine filtering membrane 4 is circular, the shell 6 of its edge and automatic vent accurate filter is closely connected, and the inner cylinder body space of automatic vent accurate filter is divided into two, a part is connected with medicinal liquid import 1, another part is connected with medicine liquid outlet 6.
2. while use, medicinal liquid enters in automatic vent accurate filter by ventilated membrane 2 by medicinal liquid import 1, shell 5 and liquid medicine filtering membrane 4 space being connected with medicinal liquid import 1 that form, ventilated membrane 2 is that one can only be passed through gas, and can not be by the thin film of liquid, gas in medicinal liquid can pass through ventilated membrane 2, air-vent 3 is discharged, liquid medicine filtering membrane 4 is owing to can only passing through liquid, and can not pass through gas, medicinal liquid can only penetrate into by liquid medicine filtering membrane 4 by liquid medicine filtering membrane 4, the space that shell 5 is connected with medicine liquid outlet 6, after being full of medicinal liquid, this space just can flow out by the top medicine liquid outlet 6 in this space, and then by whole the air in medicinal liquid emptyings, the design that medicinal liquid flows out from top medicine liquid outlet 6 also can be deposited in the undissolved nano sized particles that medicinal liquid, contingency exists the bottom of automatic vent accurate filter and not enter tube for transfusion, enter by medicine liquid outlet 6 in the medicinal liquid of tube for transfusion containing air.
Certainly, this utility model also has other embodiment, in the improvement of not leaving any technology, principle and the technique done under spiritual background of the present utility model, within all dropping on protection domain of the present utility model.
