Description

Flow type marrow treatment filtering device

Technical Field

The utility model belongs to the field of medical experimental appliances, in particular to a flow type marrow treatment filtering device.

Background

In the cell preparation process of the flow test, the cells to be detected should be single cell suspension, and since the bone marrow specimen contains bone marrow granules, blood clots and the like, the cell suspension is filtered by using nylon filter screens of 200 meshes and 400 meshes before incubating the antibody and before being tested on a computer. Therefore, the procedure of filtering the specimen with the nylon filter screen is very necessary, but most operators hold the pipette tip or pipette tip on the nylon filter screen by one hand and fix the nylon filter screen on the mouth of a clean test tube by the other hand, so that the bone marrow is filtered by the nylon filter screen and then injected into the clean test tube. In the long-term experimental operation process, the experimental operation method has a plurality of remarkable problems, part of specimens are blocked and cannot be filtered due to large clots and small filter hole diameters of filter screens, and even marrow liquid splashes onto an operation table or an operator, so that the pollution chance is increased, particularly for the specimens with blood borne diseases, the risk of the operator infecting the blood borne diseases is increased, and the specimens are wasted due to splashing of the specimens; and if the sample size is bigger, the process that the operator filters the sample one by one consumes a large amount of time and energy.

the utility model provides a STREAMING marrow handles and filters device, includes filter screen retainer plate, filter screen retainer plate and edge setting up the filter screen between last filter screen retainer plate and the filter screen retainer plate down, the lower surface of filter screen retainer plate is provided with annular test tube fixed slot down.

Furthermore, the filter screen is a funnel-shaped filter screen, and the mesh number of the filter screen is 200-400 meshes.

Further, the width of the test tube fixing groove is the same as the thickness of the test tube opening of the test tube matched with the filtering device.

Further, the outer circle diameter of going up filter screen retainer plate and filter screen retainer plate down all is greater than the test tube diameter, and the inner circle diameter all is less than the test tube diameter.

Furthermore, the edge of the funnel-shaped filter screen is fixed between the upper filter screen fixing ring and the lower filter screen fixing ring in a sealing manner.

Further, the internal surface of test tube fixed recess is provided with the hemisphere arch, the hemisphere arch sets up on the contact surface of the inner wall of test tube fixed recess and test tube and outer wall.

Furthermore, the hemispherical protrusions are point-shaped protrusions or strip-shaped protrusions.

Furthermore, the material of the hemispherical bulges is an elastic material.

Compared with the prior art, the flow type marrow treatment filtering device of the utility model has the following advantages:

through marrow filter equipment filter marrow sample can avoid splashing of marrow liquid to avoid the marrow to the pollution of operator and operation panel, guaranteed operation safety, avoid the waste of sample, make the operation of filtering the marrow more simple and convenient, practiced thrift operating time simultaneously, improve work efficiency, this device jointly uses with the STREAMING test tube of operating the computer in addition, with low costs, simple manufacture, convenient to use.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
