Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to collection device of placenta HSC filtrating.
Background
Mature blood cells in humans have a very short life span, and in the life cycle of humans, it is necessary to replenish cellular components required in the blood system at any time by hematopoietic stem cells (hereinafter, referred to as HSCs).
Currently, the preparation of HSC by collecting placenta has become an important means for preparing HSC, and in the preparation process, the operation of filtering and washing the minced placenta tissue blocks with normal saline to obtain HSC filtrate is often complicated, and usually, a metal screen is placed above a stainless steel tray, and the HSC filtrate is collected and then sucked into a 250ml centrifuge tube by a suction aid. The method reduces the efficiency of placenta preparation, increases the operation steps, and increases the risk of sample pollution; in addition, the stainless steel trays have small volumes, can collect only a few filtrates at a time, are not graduated, and have volumes out of sight, even resulting in filtrate spillage.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that preparation HSC has become an important means of preparation HSC through gathering the placenta at present, and in the preparation process, will cut garrulous placenta tissue piece and strain the operation of washing obtaining HSC filtrating with normal saline often comparatively complicated, puts metal mesh above the stainless steel tray usually, collects HSC filtrating, and the reuse helps the aspirator to absorb filtrating to in 250ml centrifuging tube. The method reduces the efficiency of placenta preparation, increases the operation steps, and increases the risk of sample pollution; in addition, the stainless steel trays have small volumes, can collect only a few filtrates at a time, are not graduated, and have volumes out of sight, even resulting in filtrate spillage.
In order to solve the above technical problem, the utility model discloses a following technical means:
a collection device of placental HSC filtrate comprises a collection device body of the filtrate; the collection device body of filtrating include centrifuging tube, funnel and screen cloth, in the centrifuging tube set up the centrifuge tube support, centrifuging tube upper portion was equipped with the inlet, the funnel bottom was equipped with the liquid outlet, in the liquid outlet of funnel can stretch into the centrifuging tube inlet, the funnel on be equipped with the opening, the screen cloth can set up in the opening.
Preferably, the present invention further provides:
the funnel is made of stainless steel.
The screen cloth be stainless steel material, the screen cloth on be equipped with the sieve mesh, the screen cloth is 150 meshes.
The centrifuge tube support be equipped with bottom plate, lateral wall and limiting plate, the centrifuge tube setting is in the thing cavity of putting that bottom plate, lateral wall and limiting plate enclose.
The diameter of the liquid outlet is smaller than that of the liquid inlet.
The centrifuge tube is 250mL, the centrifuge tube rack is 250mL, and the centrifuge tube rack and the centrifuge tube are matched in size.
The utility model relates to a collection device of placenta HSC filtrating simplifies the operation that placenta HSC filtrating was collected, and lifting efficiency, pollution reduction risk make things convenient for the volume that HSC filtrating was collected of confirming visually simultaneously.
The utility model is characterized in that:
1. the utility model discloses utilize the stainless steel funnel, simplified and strained washing operation step, increased efficiency.
2. Utilize the utility model discloses carry out placenta HSC preparation, reduced and absorb the step that filtrating shifted with the suction aid, less preparation material uses, also reduced the sample pollution risk.
3. Utilize the utility model discloses carry out placenta HSC preparation, reduced the step of collecting HSC filtrating with the stainless steel tray, but directly with the leading-in 250mL centrifuging tube of taking the scale of filtrating, the filtrating volume is visual, convenient operation, the pollution abatement risk.
4. The utility model discloses simple structure, economical and practical, and the convenience is reformed transform on current equipment and is made, convenient popularization.
