WIPO Patent Application WO/2021/214838

Kind Code:

A1

Abstract:

[Problem] The purpose of the present invention is to provide a portable anticancer agent container for preventing exposure and infection to the human body caused by chemical solution leakage that arises during a removal operation of a coupling connector at the time of system cleaning using a cleaning solution. [Solution] Provided is a pressurization-type drug injector having a drug exposure preventive function and having a system cleaning function, the pressurization-type drug injector comprising: a reservoir that has a chemical solution filling opening and a chemical solution discharging opening; a pressurization deformation means that undergoes pressurization and deformation by the injection of a chemical solution and that pushes out the chemical solution by a force caused by restoration of the pressurization and deformation; a flow rate control means that adjusts the flow rate of the chemical solution by resistance; a system cleaning port that includes a cleaning solution injection opening, a chemical solution filling opening, and a liquid discharging opening; and a case that contains therein said reservoir, said pressurization deformation means, and said system cleaning port. The case has openings respectively in the vicinity of the chemical solution filling opening, the system cleaning injection opening, and the chemical solution discharging opening. The chemical solution being filled is filled into the pressurization deformation means from the chemical solution filling opening of the reservoir, and moves from the chemical solution discharging opening of the reservoir to the exterior of the container via the flow rate control means. A cleaning solution is injected from the injection opening of the cleaning port arranged downstream from the flow rate control means, and moves to the exterior of the container. The pressurization-type drug injector having a drug exposure preventive function is characterized in that the periphery of the cleaning port is completely covered by a sterile seal, and thus, the cleaning port injection opening is kept clean until use.
