Abstract
The utility model provides a liquid medicine filter of preventing admitting air, include the upper cover and with the lower cover of upper cover butt joint, be equipped with the liquid medicine filter chamber between lower cover and the upper cover, install liquid medicine filtration membrane in the liquid medicine filter chamber, be equipped with the mounting platform of placing liquid medicine filtration membrane on the inner wall of lower cover, on cover the location boss that is equipped with the fixed liquid medicine filtration membrane of round and mounting platform cooperation, cover on liquid medicine filtration membrane top be equipped with with the communicating gas vent of liquid medicine filter chamber, the department installs the unidirectional film piece at the gas vent, hinders liquid exhaust membrane in the installation of the top of unidirectional film piece. The utility model discloses the unidirectional film piece that utilizes the setting to locate at the gas vent after closing the infusion regulator, can be avoided gaseous under the effect of atmospheric pressure and like this, need not medical personnel's secondary and exhaust through gas vent entering liquid medicine filter, has reduced medical personnel's the operation degree of difficulty, does not influence medical personnel's normal clinical operation.
Description
Technical field
The utility model is related to a kind of medicine equipment, particularly a kind of anti-air inlet liquid medicine filter.
Background technology
At present, existing hospital is during using transfusion device, after medical personnel close adjuster, due in atmospheric pressure
In the presence of, gas enters in transfusion device liquid medicine filter easily by the exhaust membrane on liquid medicine filter, and gas can be through medicine
Liquid filter and lower end ductal fluid flow out, thus causing have gas to need secondary exhaust in transfusion device, have had a strong impact on medical care
The normal clinical manipulation of personnel, increased the operation easier of medical personnel, meanwhile, also brings certain potential safety hazard to sufferer.
Content of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, and proposing one kind does not affect medical personnel
Clinical manipulation, it is to avoid bring the anti-air inlet liquid medicine filter of potential safety hazard to sufferer.
The technical problems to be solved in the utility model is achieved through the following technical solutions.The utility model is a kind of anti-
Air inlet liquid medicine filter, is characterized in：Including on lid and with the upper lower cover that docks of lid, be provided with liquid between described lower cover and upper lid
Filter chamber, is provided with liquid medicine filtering membrane in medical filtration chamber, and the inwall of described lower cover is provided with the peace placing liquid medicine filtering membrane
Assembling platform, described on cover the positioning boss being provided with the fixing liquid medicine filtering membrane of a circle and mounting platform cooperation, in liquid medicine filtering membrane
Cover on top and be provided with the exhaust outlet communicating with medical filtration chamber, being provided with exhaust ports prevents air from entering from exhaust outlet
The membrane in medical filtration chamber, is provided with above membrane and stops medical filtration chamber inner liquid medicine from flowing out from exhaust outlet
Blocking solution exhaust membrane, blocking solution exhaust membrane is fixedly connected with upper lid inwall.
In a kind of anti-air inlet liquid medicine filter technical scheme of the utility model, further preferred technical scheme feature is：
1st, it is provided with, in the center of lower cover, the support protrusion supporting liquid medicine filtering membrane upwards；
2nd, described blocking solution exhaust membrane is polyacrylate blocking solution exhaust membrane；
3rd, described liquid medicine filtering membrane is nylon or poly (ether sulfone) film;
4th, described membrane is silica gel or rubber membrane.
Compared with prior art, the utility model, using the membrane being arranged on exhaust ports, is adjusted when closing transfusion
After device, gas under atmospheric pressure can be avoided to enter liquid medicine filter by exhaust outlet, so, secondary without medical personnel
Exhaust, decreases the operation easier of medical personnel, does not affect the normal clinical operation of medical personnel；Using being arranged on membrane
The blocking solution exhaust membrane of top is it is achieved that the degassing function of liquid medicine filter, it is ensured that air will not enter human body with liquid, carries
The high security of transfusion.
