Abstract
The invention discloses a filter and an infusion apparatus used for infusion apparatus fine filtration. The filter used for infusion apparatus fine filtration comprises a filter base, a filter cover and a filter membrane which is clamped between the filter base and the filter cover. The filter base and the filter membrane form an exhaust cavity, a liquid collecting cavity is formed by the filter cover and the filter cover on the lower portion of the exhaust cavity, and a liquid inlet passage which is communicated with the exhaust cavity and a liquid outlet passage which is communicated with the liquid collecting cavity are formed in the filter cover. An exhaust passage which is communicated with the exhaust cavity is formed in the side face of the filter base, liquid which is located in the exhaust cavity is filtered through the filter membrane and enters the liquid collecting cavity, and filtered air is discharged from the infusion apparatus through the exhaust passage. The filter infusion apparatus used for infusion apparatus fine filtration can effectively discharge air in the liquid, avoids that the air is infused with the liquid into a human man blood vessel, reduces risks of medical negligence and is compact in structure, convenient to use and high in safety performance in using process.
Description
Technical field
The present invention relates to a kind of medical device, particularly relate to a kind of filter for the transfusion device secondary filter and transfusion device.
Background technology
At present, fluid transport therapy as a supplement body fluid important means and the effective measures of multiple nutritional components in 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 health of the particulate matter grave danger mankind in vein.
In the transfusion device infusion process of using common filtration; particulate matter in 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; severe one causes organ necrosis, serious crisis life.Therefore, the control of particulate matter become the problem that world's medical treatment and nursing is generally paid attention to.
For 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 the infusion process to the disease medical treatment, extensively adopt the transfusion device with end-filtration function clinically.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 because the problem of product structure easily in use produces the gathering bubble, although 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 air enters sanguimotor risk and greatly improves, and causes potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is easily to assemble bubble in order to overcome filter of the prior art, has the defective of potential safety hazard, and a kind of filter and transfusion device of being used for the transfusion device secondary filter of effectively emptying bubble is provided.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of filter for the transfusion device secondary filter, its characteristics are, this filter comprises a filter seat, one strainer cover and that coordinates with this filter seat is folded in the filter film between this filter seat and strainer cover, wherein this filter seat and this filter film consist of a discharge chamber, consist of 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 gap between adjacent described columnar projections, and described discharge chamber is communicated with by described gap with this exhaust passage.
Wherein, it is characterized in that, the pore size filter of described filter film is 5～0.2 microns.
The present invention also provides a kind of transfusion device, and its characteristics are, this transfusion device comprises described filter 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 the present invention, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge namely gets each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: the filter for the transfusion device secondary filter of the present invention is the air of emptying liquid effectively, avoids air with the logical input human vas of liquid one, has reduced the risk of malpractice.Transfusion system structure of the present invention is compact, easy to use, and in use procedure, security performance is higher.
Description of drawings
Fig. 1 is used for the cutaway view of the filter of transfusion device secondary filter in a preferred embodiment in the present invention.
Fig. 2 is the upward view of the filter seat in Fig. 1.
Fig. 3 is for along the profile after in Fig. 2, A-A dissects.
The specific embodiment
Come the clearer the present invention that intactly illustrates below in conjunction with accompanying drawing.Mode by embodiment further illustrates the present invention, but does not therefore limit the present invention among 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 coordinates with filter seat 2 is folded in the filter film 3 between this filter seat 2 and strainer cover 1, and wherein this filter seat 2 and this filter film 3 consist of a discharge chamber 42.Consist of a liquid collection cavity 41 by this strainer cover 1 and this filter film 3 below this discharge chamber 42.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.
The volume of the discharge chamber 42 in the present embodiment is greater than the volume of liquid collection cavity 41, thus the gas more effectively in filter liquide.
And can not flow out this filter from the exhaust passage in order to ensure the liquid that is arranged in discharge chamber 42, be provided with an air film 6 in the nearly exit of exhaust passage, thereby be plugged with during an aerofluxus block 5 is fixed on the exhaust passage with air film 6 in the exit of exhaust passage.
