A kind of processing and manufacturing method of special liquid storage bag for cell therapy

Abstract

The invention belongs to the technical field of cell therapy, and relates to a method for processing and manufacturing a liquid storage bag for cell therapy, which is characterized in that the liquid storage bag for cell therapy includes a first layer of film, a one-way film tube, a connection port and a second layer of film , including the following production steps: a, laying the first layer of film on the welding mold of the welding equipment; b, placing the one-way film tube and the connection port on the first layer of film; c, laying the second layer of film on the second layer of film Above the first layer of film, the second layer of film covers the one-way film tube and the connection port, and the four sides of the second layer of film are aligned with the first layer of film. In the present invention, the first welding part and the liquid medicine chamber are first formed by welding, and the one-way membrane tube and the connection port are welded and fixed, and then the first liquid medicine is filled, and then the virtual welding part is formed by weak welding, and then the second The two kinds of medicinal liquids are poured into the second medicinal liquid chamber, and finally sealed, trimmed, and opened. The process is simple and suitable for the production of the special liquid storage bag for cell therapy with two medicinal liquid chambers.

Description

technical field [0001] The invention belongs to the technical field of cell therapy, and in particular relates to a method for processing and manufacturing a special liquid storage bag for cell therapy. Background technique [0002] Cell therapy is the use of autologous or allogeneic adult cells or stem cells for disease treatment. Usually, healthy cells or stem cells are transplanted into the patient's body to supplement and replace sick cells, activate organ functions, improve organ activity, improve organ quality, delay organ disease, restore normal physiological functions of organs, and achieve disease treatment. or for anti-aging purposes. [0003] In the field of disease treatment, cell therapy has been widely used in severe diseases such as advanced liver cirrhosis, bone marrow transplantation, osteonecrosis, myocardial infarction, and tumors. [0004] In the field of health maintenance, cell therapy has been applied to delay aging and enhance physical fitness. [...

AI Technical Summary

Problems solved by technology

[0006] In order to reduce the degree of manual participation in dispensing, a liquid storage bag with multiple cavities has appeared in the prior art. The liquid storage bag is divided into two or more cavities by the virtual welded isolation part inside the liquid storage bag, and each There are different liquid medicines in each cavity. When in use, press the liquid storage bag hard to make the virtual welding isolation part stretch under the action of pressure, and mix the various liquid medicines inside the liquid storage bag, and then inject it to the patient. The unique design solves the problem of inaccurate drug measurement and easy to cause secondary pollution during the dispensing process, but when mixing the drug, it is necessary to use a certain force to continuously squeeze the liquid storage bag to open the virtual welding isolation part , but the dispensing personnel are generally female nurses with little strength, and muscle fatigue will occur during the process of continuously pressing the special liquid storage bag to mix the medicine, reducing work efficiency
