Abstract
The utility model discloses an arterial blood filter which has simple and reasonable structure and good filtering effect and exhausts smoothly. The arterial blood filter comprises a shell and a filter screen component, wherein the shell comprises an upper shell and a lower shell which are fixedly connected in a sealing way; a blood inlet is arranged at the outer side of the upper shell; a blood outlet is arranged on the lower shell; a first exhaust port is arranged on the shell and is connected with the filter screen component; a second exhaust port is arranged on the top of the upper shell; and the filter screen component comprises a dispersing shell and a filter screen. The arterial blood filter has good air and blood separating function and good performance of removing thrombus and air bubbles in blood and is convenient to use; and the first exhaust port is communicated with the interior of the filter screen so as to be capable of better exhausting the air bubbles in the filter screen and having better performance of removing the air bubbles.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of tremulous pulse Micro-Bolt Filter.
Background technology
In clinical transfusion, blood transfusion; According to the national standard requirement, use filter, existing filter generally is made up of upper and lower casing and filter membrane purifying layer; The filter membrane purifying layer is clipped between the upper and lower casing, and medicinal liquid and the blood that gets into is filtered, purifies.Yet, the filtration of the little bolt of arterial blood when common filter can not satisfy open heart operation with extracorporeal circulation.In open heart surgery with extracorporeal circulation, blood is through the tremulous pulse Micro-Bolt Filter, and effectively little bolt and the gas in the filtering blood reduces the generation of postoperative complication, has improved patient safety.The drainage screen that has in the existing tremulous pulse Micro-Bolt Filter is designed to concentric circular and arranges, and has limited the contact between the net, has increased the real area of net, and resistance was less relatively when blood passed through; The Micro-Bolt Filter that has disposes the base of location core; Core upper end, location disposes top cover; The periphery of base is put a band air vent shell, but these tremulous pulse Micro-Bolt Filters that use clinically also exist the comparatively problem of difficulty of aerofluxus at present, influence filter effect; And use inconvenience, to the patient safety poor performance.
The utility model content
The purpose of this utility model is to overcome the difficult shortcoming of Micro-Bolt Filter aerofluxus bubble in the prior art, and a kind of tremulous pulse Micro-Bolt Filter is provided, and it is simple and reasonable for structure, and aerofluxus is smooth and easy, and good filtration effect has good QI and blood separation function, uses more convenient.
For reaching above-mentioned purpose, a kind of tremulous pulse Micro-Bolt Filter that this utility model provides, the technical scheme below adopting: this utility model comprises housing and net-filter assembly; Said housing comprises upper shell and lower house; Said upper shell and lower house are sealedly and fixedly connected, and the said upper shell outside is provided with blood inlet, and said lower house is provided with blood outlet; Said housing is provided with first air vent, and said first air vent is connected in net-filter assembly.
Further, said upper shell top is provided with second air vent; Said net-filter assembly comprises and disperses housing and filter screen, and said first air vent is connected with disperseing housing.
Further, be provided with first gas collection chamber that is connected with said first air vent with the filter screen top below the said dispersion housing.
Further, said upper shell is inner is provided with second gas collection chamber that is connected with said second air vent with disperseing above the housing.
The beneficial effect of this utility model is: this utility model is simple and reasonable for structure, and aerofluxus is smooth and easy, and good filtration effect has good QI and blood separation function, gets rid of thrombosis and bubble function admirable in the blood, and is easy to use.Said second air vent can be discharged the peripheral bubble of filter screen rapidly, and said first air vent communicates with filter screen inside, can better discharge the inner bubble of filter screen, lowers staff's labor intensity, and aerofluxus is more smooth and easy, and the bubble performance is more good.

The specific embodiment
For further understanding characteristic, technological means and the specific purposes that reached, the function of this utility model; Resolve the advantage and spirit of this utility model, by the detailed description of this utility model further being understood below in conjunction with the accompanying drawing and the specific embodiment.
Shown in Figure of description; This utility model comprises housing and net-filter assembly, and said housing comprises upper shell 1 and lower house 2, and said upper shell 1 is sealedly and fixedly connected with lower house 2; Said net-filter assembly comprises and disperses housing 4 and filter screen 3; Said housing is provided with first air vent 7, and said first air vent 7 is connected in net-filter assembly, and said first air vent 7 directly is connected with disperseing housing 4.Said filter screen 3 has the double medium filtration film to constitute, and one deck is a filter course in the double medium filtration film, and another layer is a supporting layer.
Said upper shell 1 outside tangentially is provided with blood inlet 5; The top of said upper shell 1 deviates from center position and is provided with second air vent 6, and said upper shell 1 inside is provided with second gas collection chamber 9 that is connected with said second air vent 6 with dispersion housing 4 tops.Said upper shell 1 top is provided with a through hole; The top center axial location place of said dispersion housing 4 is provided with first air vent 7; Said first air vent 7 runs through the through hole at upper shell 1 top; The outer wall of said first air vent 7 and the periphery of through hole are tightly connected, and said dispersion housing 4 belows are provided with first gas collection chamber 10 that is connected with said first air vent 7 with filter screen 3 tops; Said lower house 2 central axis positions are provided with blood outlet 8, and said blood outlet 8 is connected in the arterial perfusion pipeline.
In sum; This utility model in use; Blood gets in the upper shell 1 of tremulous pulse Micro-Bolt Filter from said blood inlet 5, because the quality of bubble is low weight and consistent with the flow direction of blood, helps the separation and the discharge of bubble; Therefore get into said second gas collection chamber 9 after bubble and the blood separation, and from second air vent 6 that second gas collection chamber 9 is connected discharge.Little bolt in the blood filters through filter screen 3; Also have microbubble in the blood after said filter screen 3 filters; These microbubbles are in filter screen 3 inside, and the bubbles in the filter screen 3 can get into said first gas collection chamber 10, and from first air vent 7 that first gas collection chamber 10 is connected discharge.The blood after filtering flow out from said blood outlet 8, get into the arterial perfusion pipeline.
This utility model first air vent 7 directly is connected with filter screen 3, helps discharging the bubble in the filter screen 3 fast, so that gas bubble blockage filter screen 3 makes filtration more smooth and easy.
The above embodiment has only expressed the part embodiment of this utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to this utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from this utility model design, can also make some distortion and improvement, these all belong to the protection domain of this utility model.Therefore, the protection domain of this utility model should be as the criterion with accompanying claims.
