Device for agentia conveying

Abstract

The invention discloses a device for agentia conveying. The device comprises a container used for containing agentia, a cavity body and a valve. The cavity body comprises a cavity passage, a cavity body inlet and a cavity body outlet, the cavity body inlet is communicated with a connecting port, and the cavity body outlet faces the bottom of the container. The valve comprises a first through holeand a valve body, the first through hole is separately communicated with the cavity body inlet and the cavity body outlet, and the cavity passage is partitioned into a decompression cavity passage anda compressed cavity passage by the valve body. The provided device can convey the agentia in the container in a more stable, continuous and balanced pushing mode and a more relaxative mode, it is effectively avoided that the sudden releasing of pressure makes the agentia subjected to the reaction of the target tissue, so that the agentia covers the view of an endoscope, the administration (such as a hemostatic) is more accurate, the surgical operation continuity of the endoscope is improved, the hemostatic effect is improved, and the time of the surgical operation 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
