Abstract
The utility model relates to a liquid medicine filter which comprises an upper casing body and a lower casing body, wherein the upper casing body is butted with the lower casing body to form a liquid medicine cavity which are communicated with a liquid inlet and liquid outlet, and a filter membrane is arranged between the upper casing body and the lower casing body. The utility model is characterized in that the filter membrane comprises a draining breathing membrane and a hydrophilic membrane which are respectively and tightly combined with the upper casing body and the lower casing body. The upper casing body is provided with an exhaust hole covered by the draining breathing membrane, and the liquid inlet and the liquid outlet covered by the hydrophilic membrane are arranged on the lower casing body. The liquid medicine filter of the utility model has the advantages of simple structure, favorable filtering effect, safe and reliable use, etc.
Description
Technical field
This utility model relates to a kind of liquid medicine filter, belongs to technical field of medical instruments.
Background technology
Liquid medicine filter is used to filter the medicinal liquid of infusion or transfusion, gets rid of the bubble in the medicinal liquid simultaneously, guarantees transfusion safety.At present, the most of filtering liquid medicine of existing liquid medicine filter, the additive air filter is eliminated the air in the medicinal liquid in addition, and structure is numerous and diverse, poor filtration effect.
The utility model content
The purpose of this utility model is to provide a kind of can overcome above-mentioned defective, simple in structure, good filtration effect, safe and reliable liquid medicine filter.
Liquid medicine filter of the present utility model comprises: upper shell and lower house, upper shell docks with lower house and constitutes medicinal liquid cavity, medicinal liquid cavity is connected with liquid inlet and outlet, between upper shell and the lower house filter membrane is housed, it is characterized in that: filter membrane comprises hydrophobic permeable membrane and hydrophilic film, hydrophobic permeable membrane and hydrophilic film are combined closely respectively on upper and lower casing, have a steam vent that is covered by hydrophobic permeable membrane on the upper shell, and inlet is arranged on the lower house with the liquid outlet that is covered by hydrophilic film;
Described liquid medicine filter has intake chute on the lower house contact surface that contacts with hydrophilic film;
Described liquid medicine filter, upper shell are provided with one and flow to sign.
Because the filter membrane of this liquid medicine filter comprises hydrophobic permeable membrane and hydrophilic film, have a steam vent that is covered by hydrophobic permeable membrane on the upper shell, medicinal liquid is through filter the time, gas is wherein discharged at steam vent via hydrophobic permeable membrane, liquid process hydrophilic film filters out impurity wherein, so both do not had gas also without any other impurity in the effusive medicinal liquid of liquid outlet.Therefore, the utlity model has simple in structure, good filtration effect, advantage such as safe and reliable.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is an A-A cutaway view embodiment illustrated in fig. 1;
Fig. 3 is a B-B cutaway view embodiment illustrated in fig. 1.
The specific embodiment
1, upper shell 2, lower house 3, inlet 4, liquid outlet 5, hydrophobic permeable membrane 6, hydrophilic film 7, intake chute 8, steam vent 9, flow direction sign 10,11 bonding wires.
As shown in Figure 1, 2, 3: liquid medicine filter described in the utility model contains upper shell 1, lower house 2, inlet 3, liquid outlet 4, hydrophobic permeable membrane 5 is combined closely respectively on upper and lower casing with hydrophilic film 6, be medicinal liquid cavity between hydrophobic permeable membrane 5 and the hydrophilic film 6, medicinal liquid cavity is connected with inlet 3, and upper shell 1 has a steam vent 8.Hydrophilic film 6 all adopts ultrasonic bonding with lower house 2, upper shell 1 with being connected of lower house 2, be connected firmly like this and can not cause the weldment distortion, hydrophilic film 6 covers intake chute 7 and liquid outlet 4, and the medicinal liquid that enters from inlet 3 can directly not flow out from liquid outlet 4 through intake chute 7 like this; Hydrophobic permeable membrane 5 adopts the resistance to water medical grade adhesive bonding with being connected of upper shell 1, and infusion pressure is being not more than under the 80KPa situation, and hydrophobic permeable membrane 5 can only pass through gas, and can not pass through liquid, and long period of soaking can not see through liquid yet.Have the intake chute 7 that is connected with liquid outlet 4 on lower house 2 contact surfaces that contact with hydrophilic film 6, help the outflow of liquid, upper shell 1 is provided with and flows to sign 9 personal identifications easy to use.
During use, the medicinal liquid that comes from disposable use infusion pump or transfusion device, flow at inlet 3, the cavity that medicinal liquid flows to liquid medicine filter is that medicinal liquid is full of intracavity, as being arranged in the medicinal liquid, air can discharge from steam vent 8 by hydrophobic permeable membrane 5, medicinal liquid is penetrated in the intake chute 7 of lower house 2 after hydrophilic film 6 is filtered, and flows out through liquid outlet 4.Without any impurity, reached the requirement of international regulation through the medicinal liquid of this filter output, can be safe and reliable use for human body infusion or transfusion.
