MEDICAMENT DELIVERY DEVICE, APPARATUS AND ASSEMBLY

Document Type and Number:

WIPO Patent Application WO/2020/024953

Kind Code:

A1

Abstract:

A medicament delivery device, comprising a container (100) for accommodating medicaments, a cavity (200) and a valve (400); the cavity (200) is provided in the container (100), and comprises a cavity channel (230), a cavity inlet (210) and a cavity outlet (220), the cavity inlet (210) being in communication with an interface (300), and the cavity outlet (220) facing towards the bottom of the container (100); and the valve (400) comprises a first through hole (410) and a valve body (420), the first through hole (410) being in communication with the cavity inlet (210) and the cavity outlet (220), and the valve body (420) being placed in the cavity (200) and dividing the cavity channel (230) into a pressure-relief cavity channel (231) and a pressure-receiving cavity channel (232). The medicament delivery device is able to deliver medicaments in the container (100) in a more stable and more moderate manner, effectively preventing the medicaments from spreading all over the field of view of an endoscope under the reaction of a target tissue due to a sudden release of pressure, so that the medicaments can be administered (e.g., hemostatic agent) more accurately, and the operational continuity of an endoscopic surgery is improved, improving the hemostasis effect, and shortening the surgical operation time.
