Medicine delivery device

Abstract

The invention provides a medicine delivery device which comprises a pressure regulating component, wherein the pressure regulating component comprises a pressure regulating cavity and an emission cavity; a pressure regulating inlet of the pressure regulating cavity is connected with a catheter; an included angle formed by the cavity wall of a pressure regulating outlet and the axial direction of the pressure regulating cavity is 10 to 12.5 degrees; an emission inlet of the emission cavity is assembled with the pressure regulating outlet; and an included angle formed by the cavity wall of the emission outlet and the axial direction of the emission cavity is 5 to 6 degrees. The device provided by the invention has the advantages that medicine in a container can be delivered in a stably and continuously balanced pushing mode and a gentle mode; the condition that the medicine is spread all over the view sight of an endoscope through receiving counteraction of target tissues because of sudden release of the pressure can be effectively avoided, so that the medication (such as hemostatic medication) is more precise; meanwhile, the continuity of the endoscopic surgery operation is improved; the hemostatic effect is improved; and the surgery 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
