Abstract
The utility model discloses a filter for secondary filtering of an infusion apparatus and the infusion apparatus. The filter comprises a filter base, a filter cover and a filter membrane which is clamped between the filter base and the filter cover. An exhausting cavity is formed by the filter base and the filter membrane, and a liquid converging cavity which is composed of the filter cover and the filter membrane is arranged below the exhausting cavity. A liquid inlet passageway which is communicated with the exhausting cavity and a liquid outlet passageway which is communicated with the liquid converging cavity are arranged in the filter cover. An exhausting passageway which is communicated with the exhausting cavity is further arranged in the side face of the filter base. Liquid which is placed in the exhausting cavity is filtered by the filter membrane and then enters the liquid converging cavity, and gas which is filtered out passes through the exhausting passageway and is discharged out of the infusion apparatus. The infusion apparatus comprises the filter for secondary filtering of the infusion apparatus. The filter for secondary filtering of the infusion apparatus can effectively and completely evacuate the air in the liquid, the fact that the air is transfused into the blood vessels of a human body along with the liquid is avoided, and medical negligence risks are lowered. The infusion apparatus is compact in structure, convenient and fast to use, and high in safety performance in the process of using.

Technical field
This utility model relates to a kind of medical device, particularly relates to a kind of filter and transfusion device that is used for the transfusion device secondary filter.
Background technology
At present, fluid transport therapy as a supplement body fluid important means and the effective measures of multiple nutritional components in the body are provided, be the necessary means of clinical treatment medication.But for many years, in clinical treatment, transfusion is faced with potential danger always, i.e. blood contamination, the particulate matter grave danger human beings'health in the vein.
In using common filtering transfusion device infusion process; particulate matter in the medicine enters inside of human body in transfusion; when this particulate matter reaches a certain amount of; be easy to bring out cardiovascular and cerebrovascular disease and pulmonary embolism; the lighter may cause disturbance of blood circulation; weight person causes organ necrosis, serious crisis life.Therefore, the control to particulate matter has become the problem that world's medical treatment and nursing is generally paid attention to.
At above problem, should carry out strict control to the drug manufacture link, the production of standard infusion set and instrument used for injection and quality, but the most safe and simple and effective method is to adopt end-filtration.
At present, in infusion process, extensively adopt transfusion device clinically with end-filtration function to the disease medical treatment.But can only filter the particulate matter more than 15 microns, can not filter for getting microgranule below 15 microns.In recent years the filter of particulate matter more than 5 microns has appearred filtering in market, but, the problem of product structure assembles bubble because in use producing easily, though the top at filter is provided with steam vent, but majority can't be got rid of bubble, bubble has the risk that enters infusion pipeline at any time, thereby the sanguimotor risk of air admission improves greatly, causes potential safety hazard.
The utility model content
The technical problems to be solved in the utility model is to assemble bubble easily in order to overcome filter of the prior art, has the defective of potential safety hazard, and a kind of filter that is used for the transfusion device secondary filter and transfusion device of effectively emptying bubble is provided.
This utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of filter that is used for the transfusion device secondary filter, its characteristics are, this filter comprises a filter seat, one strainer cover and that cooperates with this filter seat is folded in the filter film between this filter seat and the strainer cover, wherein this filter seat and this filter film constitute a discharge chamber, constitute a liquid collection cavity by this strainer cover and this filter film below this discharge chamber; Also be provided with a feed liquor runner that is communicated with this discharge chamber and a fluid runner that is communicated with this liquid collection cavity on this strainer cover; The side of this filter seat also is provided with at least one exhaust passage that is communicated with this discharge chamber, and the liquid that enters this discharge chamber passes through and enters liquid collection cavity after this filter film filters, and the gas that is filtered out is discharged this transfusion device through this exhaust passage.
Wherein, the volume of this discharge chamber is greater than the volume of this liquid collection cavity.
Wherein, the exit of this exhaust passage is provided with an air film, and the aerofluxus block that is used for fixing this air film.
Wherein, the boundary with this discharge chamber in this filter seat is provided with some columnar projections, all forms a slit between the adjacent described columnar projections, and described discharge chamber is communicated with by described slit with this exhaust passage.
Wherein, the pore size filter of described filter film is 5～0.2 microns.
This utility model also provides a kind of transfusion device, and its characteristics are that this transfusion device comprises the described filter that is used for the transfusion device secondary filter; This feed pathway is communicated with a feed liquor conduit, and this liquid outlet channel is communicated with a transfusion catheter.
In this utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of this utility model.
Positive progressive effect of the present utility model is: the filter that is used for the transfusion device secondary filter of the present utility model is the air of emptying liquid effectively, avoids air with liquid one logical input human vas, has reduced the risk of malpractice.Transfusion device compact conformation of the present utility model, easy to use, security performance is higher in the use.
Description of drawings
Fig. 1 is for being used for the cutaway view of the filter of transfusion device secondary filter in the preferred embodiment in this utility model.
Fig. 2 is the upward view of the filter seat among Fig. 1.
Fig. 3 is for along the profile after A-A dissects among Fig. 2.
The specific embodiment
Come the clearer this utility model that intactly illustrates below in conjunction with accompanying drawing.Mode by embodiment further specifies this utility model, but therefore this utility model is not limited among the described scope of embodiments.
As shown in Figure 1, the filter that is used for the transfusion device secondary filter in the present embodiment, filter comprises a filter seat 2, one strainer cover 1 and that cooperates with filter seat 2 is folded in the filter film 3 between this filter seat 2 and the strainer cover 1, and wherein this filter seat 2 and this filter film 3 constitute a discharge chamber 42.Below this discharge chamber 42, constitute a liquid collection cavity 41 by this strainer cover 1 and this filter film 3.Also be provided with a feed liquor runner 11 that is communicated with this discharge chamber 42 and a fluid runner 12 that is communicated with this liquid collection cavity 41 on this strainer cover 1; The side of this filter seat 2 also is provided with the exhaust passage that is communicated with this discharge chamber 42, the liquid that enters this discharge chamber 42 from feed liquor runner 11 passes through the liquid collection cavity 41 that enters the below after this filter film 3 filters, and the gas that is filtered out is discharged this transfusion device through this exhaust passage.The pore size filter of the filter film in the present embodiment can be 5～0.2 microns.
