Description
Technical field
This utility model belongs to medical equipment, specifically is a kind of filter that is used for filtering liquid medicine on the transfusion device.
Background technology
Liquid medicine filter is mounted in the equipment of disposable transfusion device terminal, mainly is made up of housing and filter membrane, is used for the particulate matter of filtering medicinal liquid 3-5 ч.These transfusion devices the phenomenon of transfusion needle and the leakage of liquid medicine filter cooperation place often occurs when clinical use, use the many of remaining needle especially now clinically, when cooperating with liquid medicine filter once more after transfusion needle is taken off, and this phenomenon of easier appearance.
The utility model content
The purpose of this utility model is the deficiency that overcomes above-mentioned existence, and the liquid medicine filter that can effectively avoid transfusion needle and the leakage of liquid medicine filter cooperation place is provided.
For achieving the above object, the technical scheme that this utility model adopted is: a kind of liquid medicine filter, lower house by upper shell, liquid medicine filtering membrane and the band inner chamber of being with inner chamber is formed, all also have Taper Pipe on upper shell and the lower house, wherein upper shell and lower house are sealedly and fixedly connected, described liquid medicine filtering membrane is fixed between the inner chamber of upper shell and lower house, it is characterized in that: lower house is provided with the spill draw-in groove, is provided with sealing ring in the spill draw-in groove.Described spill draw-in groove is located at the Taper Pipe 6:100 place of lower house.
Liquid medicine filtering membrane described in this utility model is fixed on the interior intracavity of upper shell or lower house, and the inner chamber of upper shell and the fixing back of lower house composition is separated into two parts.
This utility model is opened a spill draw-in groove on liquid medicine filter lower house 6:100 place nose cone, join a ring packing cushion rubber in the spill draw-in groove, when liquid medicine filter cooperates with the transfusion needle stand (comprise after needle stand takes off and being assembled on the liquid medicine filter once more), the cooperation place can be from movable sealing, thereby has solved the phenomenon of cooperation place leakage.Therefore utility model is simple in structure, easy to operate, with low cost, realizes easily, is fit to extensively promote the use of.
Description of drawings
Fig. 1 is this utility model structural representation
Fig. 2 is the local enlarged diagram of A-A among Fig. 1
Among the figure: the 1-upper shell; 2 liquid medicine filtering membranes; The 3-lower house; 4-spill draw-in groove; The 5-sealing ring.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further, but protection domain of the present utility model is not limited in following embodiment.
Shown in Fig. 1-2: liquid medicine filter, form by the lower house 3 of the upper shell 1 of being with inner chamber, liquid medicine filtering membrane 2 and band inner chamber.Wherein all have a pitch cone pipe on upper shell 1 and the lower house 3, and upper shell 1 and lower house 3 be sealedly and fixedly connected, described liquid medicine filtering membrane 2 is fixed between the inner chamber of upper shell 1 and lower house 3.Be the interior intracavity that liquid filter membrane 2 is fixed on upper shell 1 or lower house 3 more accurately, and the inner chamber of upper shell 1 and lower house 3 fixing back compositions is separated into two parts.Lower house 3 is provided with spill draw-in groove 4, and this spill draw-in groove 4 is located on the lower house 6:100 place nose cone, and is provided with sealing ring 5 in the spill draw-in groove 4.Join a ring packing cushion rubber like this in the spill draw-in groove, when liquid medicine filter and transfusion needle stand when cooperating (comprise after needle stand takes off and being assembled on the liquid medicine filter once more), the cooperation place can be from movable sealing, thereby has solved the phenomenon of cooperation place leakage.
