Facility for conveying medicine and device and component of facility

Abstract

The invention discloses a facility which comprises a container, a cavity and a valve, wherein the container is used for containing a medicine; the cavity is arranged inside the container and comprisesa cavity channel, a cavity inlet and a cavity outlet; the cavity inlet communicates with an interface; the cavity outlet faces to the bottom of the container; the valve comprises a first through holeand a valve body; the first through hole communicates with the cavity inlet and the cavity outlet separately; the valve body is arranged inside the cavity and is used for partitioning the cavity channel into a pressure release cavity channel and a pressed cavity channel. By adopting the facility disclosed by the invention, the medicine in the container can be conveyed in a stable and gentle mode,the consequence that the medicine is scattered into the whole vision of an endoscope under a counteraction of target tissue as pressure is suddenly released can be avoided, dosing (such as a hemostatic) can be precise, meanwhile, the continuity of endoscope operation can be improved, the hemostatic effect can be improved, and the operation time can be shortened.

Description

technical field [0001] The invention relates to a drug delivery container, in particular to a device driven by a pressure source to deliver a drug to a target tissue, so as to facilitate the drug to play a therapeutic role in the target tissue. Background technique [0002] At present, for traumatic bleeding caused by trauma or surgery, no matter what hemostasis technique is adopted, the conventional method of "compression to stop bleeding" is inseparable. Common ones are: Band-Aids used for external trauma, and hemostatic sponges, hemostatic microspheres, hemostatic medical films and hemostatic yarns made of non-woven technology used in various operations. Although these hemostatic techniques can effectively improve the efficiency of hemostasis, they must be compressed for a period of time before removing the external force, and observe whether there is still bleeding at the wound. If there is still bleeding, you need to continue to use the hemostatic agent and apply press...

AI Technical Summary

Problems solved by technology

The device can quickly stop the bleeding target tissue, but at the moment of opening the valve, there is an instantaneous pressure release—the pressure of the injected fluid is increased instantaneously, so that the therapeutic agent has an instantaneous impact on the tissue under the pressure of the hemostatic powder, The reaction force of the action site produced by the impact on the tissue makes the hemostatic powder cover the field of vision, making it impossible to continue to observe. continuity of laparoscopic surgery
