Cell preparation storage injector

Abstract

The invention relates to a cell preparation storage syringe which comprises a storage cylinder, a syringe needle, a needle head, a needle head, a needle head, a needle head, a needle head, a needle head and a needle head, an injection port communicated with the storage cavity is formed in one end of the storage cylinder, a sealing part for sealing the storage cavity is formed in the other end of the storage cylinder, and a through hole is formed in the middle of the sealing part; the piston is matched with the storage cavity and arranged in the storage cavity, external threads are formed on the outer side face of the piston, and the piston is screwed with the storage cavity through the threads; the connecting rod is movably arranged in the through hole in a penetrating manner, and one end of the connecting rod is connected with the piston; the limiting structure is arranged between the connecting rod and the storage cylinder and used for limiting relative rotation of the connecting rod and the storage cylinder; and the injection needle is communicated with the injection port and is detachably connected with the storage cylinder. According to the invention, the pathogen pollution risk in the cell preparation injection process can be reduced, the cell damage possibility is reduced, the loss and waste of the cell preparation are reduced, the injection operation steps are simplified, and the injection efficiency is improved.

Description

technical field [0001] The disclosure relates to the technical field of medical devices, in particular to a cell preparation storage syringe. Background technique [0002] Cell preparation is a new type of clinical treatment product developed with the continuous advancement of cell technology in recent years. Due to the development of regenerative medicine, clinical research has found that the use of young, healthy stem cells or immune cells to reinfuse the body can repair cell damage, repair organ damage, and treat tumors. [0003] After the production of the cell preparation is completed, it is usually sealed and packaged in a preparation bottle, and a syringe is used to extract the cell preparation from the preparation bottle before injection. In the above process, the cells need to be transferred from the reagent bottle to the syringe and then injected. This method has the following defects: [0004] First, there may be risks of contamination by pathogens such as bacte...

AI Technical Summary

Problems solved by technology

[0004] First, there may be risks of contamination by pathogens such as bacteria, fungi, mycoplasma, and chlamydia during the process of extracting the cell preparation into the syringe;

[0005] Second, the syringe produces a large suction force during the process of extracting the cell preparation, which may damage the cells in the cell preparation and affect the curative effect of the cell preparation;

[0006] Third, when the cell preparation is transferred from the reagent bottle to the syringe, some cell preparation will inevitably remain in the reagent bottle, which will cause loss and waste of the cell preparation;

[0007] Fourth, the process of using the cell preparation needs to go through the process of extracting first and then injecting. The operation steps are cumbersome and the injection efficiency is low.
