Abstract
The utility model provides an infusion device with the function of filtering, which comprises a bottle plug puncturing device, a guide tube, a dropping tube and a dropping funnel, wherein the dropping tube is a filtering dropping tube with a filtering structure; the filtering dropping tube is installed at the upper end of the dropping funnel; and the upper end of the filtering dropping tube is communicated with the bottle plug puncturing device, or is communicated with the bottle plug puncturing device via the upper guide tube. Because the filtering dropping tube with a filtering structure is installed at the upper end of the dropping funnel, the traditional liquid medicine filter can be omitted and the infusion device with the function of filtering has simple structure, practical function and feasible technology; the utility model fundamentally solves the risk brought by air bobbles in the liquid medicine filter and the filtering dropping tube has the functions of filtering liquid medicines and realization of observing infusion drops, so the fabrication cost is saved; the filtering dropping tube can be applied to various types of infusion device products, is cheap and high-efficient, and has a realistic significance to improve the infusion safety.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of transfusion device with filtering function.
Background technology
Existing transfusion device is made up of bottle plug puncture unit, conduit, dropping funnel, dropper and liquid medicine filter, liquid medicine filter generally is positioned at the transfusion needle position near the transfusion end, under majority transfusion situation, all keep bubble in the liquid medicine filter, these bubbles are when changing medicinal liquid or patient posture and move, very easily enter human vas, patient is damaged, cause dispute.Although there is the transfusion device patented technology of multiple anti-bubble constantly to propose at home, none can solve the problem that all keeps bubble in the liquid medicine filter.The transfusion device of injection moulding dropping funnel type moves on to the dropping funnel below to filter, and is helpful to reducing bubble to a certain extent, but because of manufacture is loaded down with trivial details, complex process, cost is too high, many decades occurs and fails to popularize at home.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, provide a kind of simple in structure, can directly omit traditional drugs liquid filter accessory and can effectively prevent the transfusion device with filtering function of the built-in air bubble problem of filter.
The technical solution of the utility model is achieved in that a kind of transfusion device with filtering function, comprise bottle plug puncture unit, conduit, dropping funnel and dropper, be characterized in that described dropper is the filtration dropper that is provided with filtration, described filtration dropper is installed on described dropping funnel upper end, and described filtration dropper upper end is connected with described bottle plug puncture unit or is connected with described bottle plug puncture unit through upper conduit.
Wherein, described filtration dropper is that the filtering material with filtration is formed, and can coat dropper with filter membrane and make, also can be directly with a kind of semi-rigid filter material straight forming.Filtration dropper described in the utility model can be the filter membrane that comprises a stay pipe and coating stay pipe, also can be the stylostome of being made by semi-rigid filter material for and offer a plurality of miniature filtering holes on it, can also be to comprise a stylostome of being made by semi-rigid filter material and the filter membrane that is coating stylostome.Filtration dropper described in the utility model possesses the performance of dropper and medical filtration, medicinal liquid is flowed through when filtering dropper, through just entering dropping funnel after the filtering material filtration, filtering the dropper base area does not reduce, has good extension liquid ability, do not influence the essential observation of dropper and drip several functions, both realized medical filtration, keep the dropper function again.
Modes such as filtration dropper described in the utility model can connect by bonding, heat seal, tapering, screw thread spins are connected with dropping funnel and bottle plug puncture unit.
This utility model will be owing to will be provided with the upper end that the filtration dropper of filtration is installed in dropping funnel, thereby can omit the liquid medicine filter that conventional version is installed, so it is simple in structure, the function practicality, feasible process, fundamentally solve the risk that the built-in bubble of liquid medicine filter is brought, and described filtration dropper has the two aspect performances of medicinal liquid being filtered and realizing observing number of infusion drops, therefore saved manufacturing cost.In sum, filtration dropper described in the utility model can be applicable on the infusion apparatus product of various types, and Cheap highly effective has realistic meaning to improving transfusion safety.
Below in conjunction with accompanying drawing this utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, transfusion device with filtering function described in the utility model, comprise bottle plug puncture unit 1, conduit 2, dropper and dropping funnel 4, wherein said dropper is the filtration dropper 3 that is provided with filtration, described filtration dropper 3 is installed on described dropping funnel 4 upper ends, and described filtration dropper 3 upper ends are connected with described bottle plug puncture unit 1 or are connected with described bottle plug puncture unit 1 through upper conduit 2.The upper end of the described filtration dropper 3 of the present embodiment directly mode by heat seal is connected with described bottle plug puncture unit 1 and communicates, and its lower end also is that the mode by heat seal is connected with the upper end of described dropping funnel 4 and communicates.
Wherein, the described filtration dropper 3 of present embodiment comprises a stay pipe 31 and a filter membrane 32 that is coating stay pipe 31.As shown in Figure 1, described stay pipe 31 is a siphunculus that is communicated with up and down, described stay pipe 31 can be made by general material, its upper port directly is connected with described bottle plug puncture unit 1, can certainly be connected with described bottle plug puncture unit 1 through conduit 2, its lower port stretches in the described dropping funnel 4 and is connected with dropping funnel 4; And described filter membrane 32 is upper end port lower end closed and U type film that have filtering function, and described filter membrane 32 is made by the soft material with medical filtration performance, as making with the soft filter film.Certainly, filtration dropper 3 described in the utility model stylostome also that can directly be made by semi-rigid filter material with and that offer a plurality of miniature filtering holes on it replaces, have equally and filter and two kinds of functions of dropper, can also be with a stylostome and a filter membrane 32 that is coating stylostome of making by semi-rigid filter material, such filtration dropper 3 has double medium filtration, and its filter effect is better.
During use, bottle plug puncture unit 1 is inserted in the medicinal liquid bottle, after medicinal liquid enters the stay pipe that filters dropper 3 through bottle plug puncture unit 1, the filtering material 32 that is being coated stay pipe 31 blocks and filters, and filters the back medicinal liquid and oozes out from filtering material 32 bottoms and flow into dropping funnel 4, after medicinal liquid is assembled in dropping funnel 4 and finished aerofluxus, enter downcomer 2 again, form drop, regulate to observe behind the flow velocity and drip number, thereby realize filtering, observing and prevent bubble synchronously.Both save cost, fundamentally solved the risk that the built-in bubble of liquid medicine filter is brought again.
Although this utility model is to describe with reference to specific embodiment, this description and not meaning that is construed as limiting this utility model.With reference to description of the present utility model, other of the disclosed embodiments change, and all can expect for those skilled in the art, and this variation should belong in the affiliated claim institute restricted portion.
