Description

Cell harvesting bracket for cell culture bag

Technical Field

The utility model relates to a cell culture field specifically indicates a cell harvesting support for cell culture bag.

Background

In recent years, immunocytotherapy techniques have been rapidly developed, and have attracted attention as a fourth tumor treatment means following surgery, radiotherapy and chemotherapy. The immune cell treating technology includes collecting human peripheral blood, umbilical cord blood or placenta blood, separating to obtain immune cells, inducing culture in vitro to expand the immune cells greatly and enhance the target killing function, and returning the cells to patient to kill pathogen, cancer cell, mutant cell, etc. in blood and tissue. The problem of harvesting large numbers of expanded cells from culture bags before they are returned to the patient. At present stage the cell harvest mode is single, and the laboratory technician left hand is held the culture bag top, and the right hand is with hemostatic forceps clip cell culture bag pipe front portion apart from the mouth of pipe 5cm department, raises the culture bag and topples over, because liquid pressure can reduce gradually, at the in-process of toppling over, still need constantly to change the position that the culture bag was held to the left hand to it is higher to lift the culture bag. Meanwhile, the immune cells are cultured in a large scale, the loading of the culture medium is between 1.8L and 2.0L, and the weight brings great inconvenience to the experimenter in the cell harvesting process. In addition, the liquid in the culture bag can not be poured at one time and is finished, a next pouring gap is waited, the catheter can only be clamped by the hemostatic clamp to stand on the operating table, and due to the low position, hands of an experimenter can pass through the upper part of the catheter port inadvertently, and the risk of pollution is caused.

The patent number is CN 201820814939.5's Chinese utility model patent, scalable pillar can make the cell culture bag be in different high-order, adjustable angle's upper portion layer board can the effective control liquid flow rate, the pipe draw-in groove of upper portion layer board one side, make the pipe can be in the high-order all the time toppling over the clearance, the problem is solved, but this kind of structural stability is not high, overturn to a department when upper portion layer board, when making the slope of cell culture bag, because the weight of cell culture bag itself and cell culture bag only have a flexible pillar supporting mechanism, can make the upper portion layer board unstable that stands, the accident of collapsing of taking place to incline, cause the harm for the cell culture solution.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to solve above-mentioned problem, provide a cell harvesting support for cell culture bag that stability is high.

In order to solve the technical problem, the utility model provides a technical scheme does: a cell harvesting bracket for a cell culture bag comprises a supporting table, wherein an articulated piece is arranged in the middle below the supporting table, a vertical rod is articulated below the articulated piece, a connecting block is arranged below the supporting table and close to one side, a T-shaped groove is arranged below the connecting block, a T-shaped inserting block matched with the T-shaped groove is arranged in the T-shaped groove, a connecting rod is arranged below the T-shaped inserting block, an external thread is arranged on the outer side surface of the lower end of the connecting rod, a base is arranged below the supporting table, a sleeve is arranged above the base and corresponding to the connecting block, an internal thread is arranged in the sleeve, the external thread of the sleeve is in threaded connection with the internal thread of the connecting rod, the vertical rod is vertically connected with the upper surface of the base, the distance from one end of the base away from the sleeve to the vertical, at least two hooks are hinged in the rectangular groove, and a limiting block is arranged below the support table and close to the hinged piece.

The side surface of the supporting table, which is far away from the rectangular groove, is provided with a transverse plate through a steering head, and the free end of the transverse plate is provided with a C-shaped snap ring close to the supporting table.

Compared with the prior art, the utility model the advantage lie in: the utility model can be used as the initial stage when adding the culture solution, the needle tube is arranged in the C-shaped snap ring, the cell culture solution bag is arranged on the support platform and can be used as the support platform, the support platform and the base are connected through the connecting rod and the vertical rod, the support is more stable, when the cell is extracted as the harvest, the hook is turned over, the hanging hole of the cell culture solution bag is connected with the hook in a buckling way, then the connecting rod is unscrewed to leave the sleeve, and the support platform is turned over to the limiting block to be contacted with the vertical rod, at the moment, the support platform is in an inclined state, because the distance between the support platform and the vertical rod through the vertical rod and the end of the base far away from the sleeve is larger than the distance between the support platform and the vertical rod, the support force is enough for the cell culture solution bag on the outer surface of the support platform in the turning, the stability of the device is improved.
