Abstract
The invention discloses a filtering device for a blood perfusion apparatus. The filtering device comprises a circular frame (1) and a filter mesh (2). The filtering device is characterized in that the top end of the outer edge of the circular frame (1) is provided with a circular terrace (3). The filtering device is simple in structure and unique in design, the circular terrace at the top end of the outer edge of the circular frame provides better sealing effect so that it is rare that an adsorbent in a perfusion device leaks via a gap between the circular frame and the inner wall of the perfusion device and enters circulating blood, causing blood contamination.
Description
Technical field
The present invention relates to a kind of blood purification medical device, particularly relate to the filter screen of blood perfusion device.
Background technology
In recent years, blood purification therapy is in China's universal and development rapidly.Wherein hemoperfusion is one of important way of blood purification.At present, blood perfusion technique is widely used in clinical, not only has good curative effect to serious symptom poisonous substance, drug intoxication, and also can be used for the treatment of many chronic and refractories and difficult disease.Therefore the demand of single use blood perfusion device increases year by year.
Blood perfusion device, in blood purification process, is connected on and guides in external circulation bloody path, and when blood flows through tank body, adsorbent is by the toxicant absorption in blood, and the blood be cleaned enters body-internal-circulation again.Conveniently load and purify the blood adsorbent used in perfusion device, perfusion device middle level filter cylinder and top cap are set to dismountable structure.Between perfusion device middle level filter cylinder and top cap, filter screen is housed, during for stoping blood purification, adsorbent and shed particles enter blood circulation.In prior art, filter screen is all be fitted in perfusion device with top cap, all the time gap is had between the annulus frame edge of filter screen and perfusion device inwall, perfusion device is in blood purification process, often having adsorbent and micropowder to enter in circulation bloody path along the gap between annulus frame edge and perfusion device inwall causes blood contaminated, has high potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of edge and the effective perfusion device filter screen of perfusion device inner wall sealing.
Technical scheme of the present invention is as follows: a kind of perfusion device filter screen, comprises annulus frame and filter screen, and its key is: the top of described annulus frame outer is provided with round platform.Perfusion device inwall and assembling place of annulus frame, to adapt forming station terrace with the round platform of annulus frame outer, adapts with annulus frame lower surface simultaneously, and to annulus frame spacing also forming station terrace, just defines small one and large one annular table terrace of diameter.Contact position between annulus frame perfusion device inwall forms two places and turns round, therefore adsorbent, not easily from the gap leakage between annulus frame and perfusion device inwall, pollutes blood in the process purified the blood.
Have cannelure as the lower surface optimizing above-mentioned annular circular ring frame, described filter screen embeds in cannelure, and filter screen and annulus frame injection molded, in conjunction with more firm.
Beneficial effect: the present invention has that structure is simple, design is unique, the round platform of the top setting of annulus frame outer, sealing effectiveness is better, makes the gap leakage of adsorbent not between The book of Changes annulus frame and perfusion device inwall in perfusion device, enter blood circulation, blood is polluted.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the present invention and the installation diagram pushing up cap, middle level filter cylinder.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, a kind of perfusion device filter screen of the present invention, be made up of annulus frame 1 and filter screen 2, the top of described annulus frame 1 outer is provided with round platform 3.Described annulus frame 1 lower surface has cannelure 4, and described filter screen 2 edge embeds in cannelure 4.
As shown in Figure 2, top cap 6 is assembled together with middle level filter cylinder 5, spacing up and down to filter screen, filter screen is fixed on middle level filter cylinder 5 inwall, the round platform 3 that the annulus frame 1 of filter screen and top, outer are arranged forms two right-angle turnings with middle level filter cylinder 5 contact internal walls place, and the adsorbent in perfusion device and microgranule not easily penetrate into blood circulation.
Although be below described the preferred embodiments of the present invention by reference to the accompanying drawings; but the invention is not restricted to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic instead of determinate; those of ordinary skill in the art is under enlightenment of the present invention; under the prerequisite without prejudice to present inventive concept and claim; can make like multiple types and representing, such conversion all falls within protection scope of the present invention.
Claims (2)
1. for a defecator for blood perfusion apparatus, comprise annulus frame (1) and filter screen (2), it is characterized in that: the top of described annulus frame (1) outer is provided with round platform (3).
2. a kind of defecator for blood perfusion apparatus according to claim 1, is characterized in that: described annulus frame (1) lower surface has cannelure (4), and described filter screen (2) embeds in cannelure (4).
