Administration method and device thereof

Abstract

The invention provides an administration method, which includes the following steps that: a fluid is introduced into a container for holding a medicament, so that the fluid flows along a pressure relief channel, and discharged at a pressure relief through hole of the container, after the flow velocity of the fluid is stabilized, during use, the pressure relief through hole is closed and the fluidenters into a pressurized channel, flows along the pressurized channel, is discharged from the outlet of the pressurized channel and the medicament is pushed into the outlet of the container. The method provided by the invention can deliver the medicament in the container in a more stable and consistently balanced manner and in a more gradual manner, effectively avoiding the medicament being spread on the mirrored field due to the counteraction of target tissue caused by the sudden release of pressure, making administration (such as hemostatic agent) more precise, improving the continuity of the laparoscopic operation, improving the hemostatic effect, and shortening the operation time.

Description

technical field [0001] The present invention relates to a drug delivery method, in particular to a method for delivering medicine in a container, and a delivery device, so as to facilitate the medicine to exert a therapeutic effect on the target tissue. Background technique [0002] Compounds and polymers with therapeutic and preventive effects on diseases can only achieve good drug effects in vivo if they are administered to patients in an appropriate technical manner. Oral administration is the most common technique for administering compounds and polymers with therapeutic and prophylactic effects to patients, as well as injection, transdermal, pulmonary and nasal administration. In order to extend the dosing interval and improve the patient's compliance, the technology of chemical coupling or embedding of compounds or polymers has been produced to improve the bioavailability of drugs and keep them in the therapeutic window for a longer time, reducing the Drug side effect...

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
