Title:
MEDICINAL FLUID SUPPLY CONTROL DEVICE AND INJECTION LIQUID INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/168277
Kind Code:
A1
Abstract:
The present invention provides a medicinal fluid supply control device capable of performing a quick "priming" which is a preparatory operation for injecting medicinal fluid into a patient by removing air in the medicinal fluid or between the medicinal fluid and the medicinal fluid in advance by means of a filter for removing air provided on a discharge path inside the medicinal fluid supply control device, and reducing unnecessary loss of the medicinal fluid, generated during a discharge of the medicinal fluid in order to remove the air in the medicinal fluid or between the medicinal fluid and the medicinal fluid. In addition, the present invention provides a medicinal fluid supply control device capable of quickly injecting an increased amount of medicinal fluid, by removing air between the medicinal fluid and the medicinal fluid, which can be generated by a difference in flow rate of the medicinal fluid flowing in the medicinal fluid supply control device, by means of a filter for removing air provided on a discharge path inside the medicinal fluid supply control device, and of directly and easily adjusting, by a user, the injection amount of the medicinal fluid as required.
