Abstract
The utility model relates to a novel filter for an infusion apparatus, which is provided with a two-layer structure. The novel filter for the infusion apparatus comprises a filter body and an outer cover, wherein the filter body comprises an upper cover and a lower cover; inner chambers are arranged in both the upper cover and the lower cover; a through hole is formed at the bottom of the inner chamber of the upper cover and communicated with an upper connector arranged at the top end of the upper cover; a lower connector is arranged at the bottom of the lower cover; the upper end of the lower connector is communicated with the inner chamber of the lower cover; and a filter membrane is arranged in a cavity between the upper cover and the lower cover; an outer cover wraps the entirety of the outer sides of the upper cover and the lower cover which are connected together; the outer cover is tightly bonded with the filter body so as to form an entirety; and the outer cover is deep in color and the filter body is transparent. The utility model adopts the two-layer structure and the two layers are tightly bonded together, so that rotation can not be caused; the inner layer is transparent and the outer layer is deep in color, so that the problem of insufficient light during the infusion process can be solved, and the problem that the pigment in the filter enters liquid medicine during the infusion process can be prevented, and the application prospect is very good.
Description
Technical field
This utility model relates to a kind of medical transfusion apparatus, specifically relates to a kind of novel transfusion device filter, belongs to technical field of medical instruments.
Background technology
At present, the time need lucifuge in transfusion, to keep away ultraviolet intravenous pharmacy more and more, light, ultraviolet have bigger influence to this kind medicine, some medicine can decompose under the effect of light, go bad, variable color and reduction drug effect, that have even can produce noxious substance, as the cardiovascular medication: medicines such as sodium nitroprusside, nifedipine, nimodipine, Propranolol, therefore must take the lucifuge measure.Transfusion for this kind specific (special) requirements, because filter etc. all is water white, generally all be to adopt to coat dark cloth bag at present in the outside of transfusion device, dark cloth bag is from moving to down, transfusion device integral body is sealed, reach lucifuge, keep away ultraviolet purpose.But when adopting this method, owing to can't see the situation in the filter, can't know the process of transfusion, in order to prevent that filter from taking place to leak or stop up, therefore will perforate on cloth bag, the transfusion situation of checking frequently is in the hole on opening cloth bag, have light leak and enter, still can exert an influence medicine.In addition, adopt very long dark cloth bag with transfusion device all cover get up to infuse also very unbecoming.
Also have hospital directly to adopt the method for dark filter, still, present dark filter all is directly to add pigment in raw material, in when transfusion, these pigment can be owing to the effect of medicine be dissolved, and is mixed in liquid medicine and enter human body, human body is had side effects on the contrary, cause therapeutic effect bad.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel transfusion device filter, adopt double-layer structure, the outside of transparent filter inside increases the dark outer housing of one deck, so not only solved the problem of lucifuge, also can see the situation of the inside transfusion simultaneously by outer housing, can in time grasp the transfusion situation.
For achieving the above object, this utility model is to realize by following technical scheme:
A kind of novel transfusion device filter, it is characterized in that described transfusion device filter has double-layer structure, comprise filter body and outer housing, described filter body comprises loam cake and lower cover, loam cake and under cover and be equipped with inner chamber, bottom at the inner chamber of loam cake is provided with through hole, and is located at the vertical interface of going up of loam cake and communicates; Bottom at lower cover is provided with lower interface, and the upper end of lower interface communicates with the inner chamber of lower cover, is connected by concavo-convex step between loam cake and the lower cover, is provided with filter membrane in the cavity between loam cake and lower cover; In the outside of loam cake that links together and lower cover, integral coating has outer housing, fits tightly with filter body, forms an integral body, contains pigment in the described outer housing, is dark color, and described filter body is a transparence.
Aforesaid novel transfusion device filter is characterized in that being provided with annular brace rod on the inner cavity surface of the lower cover that contacts with filter membrane.
Aforesaid novel transfusion device filter is characterized in that described outer housing is brown or brown.
Aforesaid novel transfusion device filter is characterized in that described outer housing is made of plastics.
The beneficial effects of the utility model are: novel transfusion device filter of the present utility model, adopted double-layer structure, fit tightly each other, can not rotate, and internal layer is transparent, and skin is dark, has both guaranteed the problem of the lucifuge in the infusion process, prevented that also pigment in the infusion process middle filtrator from dissolving into the problem in the liquid medicine, application prospect is very good.
Description of drawings
Fig. 1 is the front view of transfusion device filter of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Among the figure: 1 is transfusion device filter, and 2 is last interface, and 3 is lower interface, and 4 is lower cover, and 5 is outer housing, and 6 is brace rod, and 7 is filter membrane, and 8 is loam cake.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is done concrete introduction.
Fig. 1 is the front view of transfusion device filter of the present utility model; Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
As shown in the figure, novel transfusion device filter 1 of the present utility model has comprised double-layer structure: outer housing 5 and filter body.Filter body comprises loam cake 8 and lower cover 4, is equipped with inner chamber on loam cake 8 and lower cover 4, and after loam cake 8 and lower cover 4 were bonded together, inner chamber each other formed the filter cavity.Bottom at the inner chamber of loam cake 8 is provided with through hole, and is located at the loam cake 8 vertical interfaces 2 of going up and communicates.Be provided with lower interface 3 in the bottom of lower cover 4, the upper end of lower interface 3 communicates with the inner chamber of lower cover 4, is connected by concavo-convex step between loam cake 8 and the lower cover 4, is provided with filter membrane 7 in the cavity between loam cake 8 and lower cover 4.
In the outside of loam cake 8 that links together and lower cover 4, integral coating has outer housing 5, fits tightly with filter body, forms an integral body.Contain pigment in the outer housing 5, be dark color.For ease of making, outer housing 5 can adopt the plastics manufacturing, increases pigment during fabrication in raw material, makes it be dark, but can also see the transfusion situation of filter body the inside by outer housing 5, such as brown, brown etc.Filter body is a transparence.
