Abstract
The invention relates to a plasma filter which is good for the uniform flow of the plasma. The plasma filter comprises a plasma filter cavity which is formed by connecting a circular upper cover with an input port and a circular lower cover with a delivery outlet, and a filter element which is arranged in the cavity. The plasma filter is characterized in that both of the input port on the upper cover of the filter and the delivery outlet on the lower cover are arranged on the centres of the upper cover and the lower cover, the inside of the upper cover takes the shape of an arch, the surface of the inside of the lower cover is uniformly distributed with a plurality of annular grooves with different diameters taking the centre of the lower cover and is also provided with a diametrical straight flute. The upper cover of the filter is provided with two input ports and the lower cover is provided with an input port. The plasma filter of the invention has the advantages that through using the principle of hydromechanics, the upper cover take the shape of an arc, the inside surface of the lower cover is provided with a circular recess and the straight flute, thus when the plasma flows out of the filter, the plasma can flow evenly conveniently, achieving the effects of absorption and filtering, and being more smooth when the plasma outflows.
Description
Technical field
Patent of the present invention relates to the correlative technology field of medical apparatus and instruments, particularly a kind of even mobile plasmafilter of blood plasma that is beneficial to.
Background technology
Compacting ring and filter membrane were formed in the middle of former general plasmafilter was added by upper and lower covers, because its diameter is excessive, caused blood through out-of-date, and it is not smooth to flow.
Summary of the invention
The purpose of patent of the present invention is for a kind of even mobile plasmafilter of blood plasma that is beneficial to is provided, solved former general plasmafilter when filtering since blood plasma flow not smooth, the problem that causes filter effect to descend.
For achieving the above object, patent of the present invention has adopted following technical scheme:
Patent disclosure of the present invention a kind of even mobile plasmafilter of blood plasma that is beneficial to, comprise the plasmapheresis cavity that is formed by connecting by circular upper cover that has the input port and the circular lower cover that has delivery outlet, and be provided with filter element in the cavity, it is characterized in that: input port on the filter cover and the delivery outlet that covers down all are positioned at, the center of lower cover, and the inboard of loam cake is arch, being evenly distributed with a plurality of on the lower cover inner surface is the circular trough of the different-diameter in the center of circle with the lower cover center, also is provided with four diametric straight troughs with the lower cover eight equal parts on the lower cover inner surface.
Described filter cover is provided with two input ports, covers down and is provided with a delivery outlet.
The advantage of Patent equipment of the present invention is: utilize hydromechanical principle, loam cake overarches, and the lower cover inner surface is provided with circular trough and straight shape groove, can flow uniformly when being convenient to the blood plasma outflow filter, reaches absorption and filtering effect, and is more smooth and easy during outflow.
Description of drawings
Fig. 1 is the structural representation of patent of the present invention.
Fig. 2 is the loam cake inside structure sketch map of patent of the present invention.
Fig. 3 is the lower cover inside structure sketch map of patent of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples patent of the present invention is further described.
A kind of even mobile plasmafilter of blood plasma that is beneficial to, as Fig. 1, Fig. 2, shown in Figure 3, comprise the plasmapheresis cavity that is formed by connecting by circular upper cover 1 that has two input ports 3 and the circular lower cover 2 that has a delivery outlet 4, and be provided with filter element 6 in the cavity, input port 3 on the filter cover and the delivery outlet 4 that covers down all are positioned at, the center of lower cover, and the inboard 8 of loam cake 1 is arch, being evenly distributed with a plurality of on lower cover 2 inner surfaces is the circular trough 5 of the different-diameter in the center of circle with the lower cover center, also is provided with four diametric straight troughs 7 with the lower cover eight equal parts on lower cover 2 inner surfaces.
Claims (1)
1. one kind is beneficial to the even mobile plasmafilter of blood plasma, comprise the plasmapheresis cavity that is formed by connecting by circular upper cover that has the input port and the circular lower cover that has delivery outlet, and be provided with filter element in the cavity, it is characterized in that: input port on the filter cover and the delivery outlet that covers down all are positioned at the center of upper and lower cover, and the inboard of loam cake is arch, being evenly distributed with a plurality of on the lower cover inner surface is the circular trough of the different-diameter in the center of circle with the lower cover center, also is provided with four diametric straight troughs with the lower cover eight equal parts on the lower cover inner surface; Described filter cover is provided with two input ports, covers down and is provided with a delivery outlet.
