MULTI-COCK IN WHICH FILTER IS EMBEDDED
Document Type and Number:
WIPO Patent Application WO/2019/212186
Kind Code:
A1
Abstract:
In the present invention, injection holes and discharge holes are formed on horizontal surfaces having different vertical positions so as to allow for selective communication with filters mounted in a filter part, thereby enabling foreign material, having been filtered out from a previously selected liquid medicine, to be prevented from flowing according to the direction change of the corresponding filter into the body when a cock handle of a multi-cock is operated such that the type of liquid medicine to be injected into the body is changed. In addition, the present invention allows the cock handle of the multi-cock to be operated, and changes the path of a liquid medicine through the injection holes, the filters and the discharge holes so as to enable the liquid medicine to be more conveniently injected.
