Abstract
The utility model provides an oxygen filter, which is mainly used for filtering the oxygen in the extracorporeal circulation of the open heart surgery in order to remove impurities in the oxygen. The oxygen filter is characterized in that a filter plate is made of the micro titanium powder, and the periphery of the filter plate is sheathed with an annular sealing ring. The maximum diameter of the hole of the filter plate is 11.00 to 13.00 mu m, the filtration accuracy is 0.05 to 0.20 mu m, the air permeability of the filter plate is 1.6*10<-3 >l/cm< 2 >. minute /mm water column, and the compressive strength is 15 to 20 kg/cm < 2 >. The utility model has the advantages of high strength, big safety factor, big air flux, good filter effect, convenient wash and disinfection, and repeat use. The price of the utility model is 1/2 to 2/3 of that of the import like product.
Description
The utility model relates to a kind of filter.Be a kind of medical oxygen filter specifically.
Oxygen filter is the device on the oxygen channel in the cardiac operation under direct vision extracorporal circulatory system, and main effect is the impurity in the elimination oxygen, guarantees that the oxygen that enters oxygenator reaches certain clarity, prevents that the impurity in the oxygen from entering the blood that carries out oxygenate.The oxygen filter of widespread usage is made up of the oblate shell therebetween one deck filter paper that has blow vent of a pair of symmetry clinically at present.Its weak point is: 1. filter paper intensity is low, and cracky also is difficult for after the breakage finding.2. be afraid of humidity, disinfect the conditional request height.3. be disposable use, waste bigger.And the cost height, each about 5 dollars.
The purpose of this utility model is to provide a kind of intensity height for fear of weak point of the prior art, and cracky is not sterilized reused oxygen filter easily.
The purpose of this utility model realizes by following measure, a kind of oxygen filter, comprise an a pair of oblate shell (1) and a filter course (3) that has blow vent, its special character is: described filter course is little titanium powder filter plate, and periphery is with an O-ring seal (2).
The thickness of filter can be 0.5～1.5mm in the above-mentioned measure, and the maximum diameter of hole on the filter can be 11.00～13.00 μ m.
Accompanying drawing be embodiment of the utility model partly cut open schematic diagram.
Embodiment is described below of the present utility model in conjunction with the accompanying drawings:
Oxygen filter of the present utility model is made up of a pair of oblate shell (a 1) filter of therebetween (3) that has blow vent.The periphery of filter is with an O-ring seal (2), with the enhanced leaktightness effect.The most handy natural rubber of sealing ring or lactic acid or silica gel are made.There is blow vent in the dome central authorities of oblate shell (1), and an end is air inlet (6), and the other end is gas outlet (5).Shell is made by lucite or transparent plastic, and 4～6 dividing plates (4) are respectively arranged on the inwall of two shells, can divide stream.Two oblate shells are to install in the mode that fastens, and seal in bonding mode.Filter (3) adopts rolling method to make with little titanium powder.Preferably one side simultaneously is rolled into thick little titanium powder with thin little titanium powder.The filtering accuracy of filter is by the size control in fine flour aperture.The maximum diameter of hole of filter is 11.00～13.00 μ m, and filtering accuracy is 0.05～0.20 μ m.When filter was installed, fine flour was to gas outlet (5), and asperities, is communicated with air inlet during use air inlet (6) with oxygen cylinder, and the gas outlet is communicated with oxygenator.Oxygen enters oxygenator through air inlet by filter.After repeatedly using, available oxygen recoils to filter, reaches the purpose of cleaning.
Through test, the permeability of filter is 1.6 * 10 in this utility model
-3L/cm
2, branch/mm water column.Compressive resistance is: 15～20kg/cm
2
Compared to existing technology, this utility model has following advantage:
1. filter compressive resistance height is not fragile, the safety coefficient height.
2. good, nontoxic, tasteless with the tissue compatibility, do not produce chemical reaction and pollution; Resistance is little, flow is big, and good filtration effect conforms to clinical requirement.
3. easy cleaning, easily sterilization can repeatedly be used, and cost is low, price only is 1/2～2/3 of import same device.
Claims (2)
1, a kind of oxygen filter comprises a pair of filter courses (3) that have the oblate shell (1) of blow vent and be clipped in two oblate shell centres, and it is characterized in that: described filter course is little titanium powder filter plate, and periphery is with an O-ring seal (2).
2, oxygen filter according to claim 1 is characterized in that: the thickness of filter (3) is 0.5～1.5mm, and the maximum diameter of hole of filter is 11.00～13.00 μ m.
