Device for conveying medicament as well as equipment and assembly comprising same

Abstract

The invention discloses a device. The device comprises a container, a cavity and a valve, wherein the container is used for containing a medicament; the container is internally provided with the cavity, and the cavity comprises a cavity channel, a cavity inlet and a cavity outlet, wherein the cavity inlet is communicated with a connector, and the cavity outlet faces the bottom of the container; anthe valve comprises a first through hole and a valve body, wherein the first through hole is communicated with the cavity inlet and the cavity outlet, the valve body is arranged in the cavity, and the cavity channel is divided into a pressure relief cavity channel body and a compressive cavity channel body. According to the device, the medicament in the container can be conveyed in a more stableand gentler manner, so that the phenomenon that the medicament undergoes the reaction of target tissue and is fully distributed in the field of view of an endoscope due to the fact that the pressure is suddenly released can effectively avoided, the drug administration (such as a hemostatic) is more accurate, meanwhile, the continuity of an endoscopic surgery operation is improved, the hemostatic effect is improved, and the operation time is 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 medicine to a target tissue, so as to facilitate the medicine to exert a therapeutic effect on the target tissue. Background technique [0002] At present, for traumatic bleeding caused by trauma or surgery, no matter what kind of hemostasis technique is used, it is inseparable from the conventional means of "compression hemostasis". Common ones are: Band-aids for external trauma, and hemostatic sponges, hemostatic microspheres, hemostatic medical membranes and hemostatic gauze made by non-woven technology used in various operations. Although these hemostasis techniques have effectively improved the hemostatic efficiency, they must be compressed for a period of time before the external force is removed, and it must be observed whether there are still bleeding points at the wound. If there is still bleeding, continue to use hemostatic ag...

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
