Colloidal particle controllable targeted pneumatic atomization drug delivery device

Abstract

The invention discloses a colloidal particle controlled targeted pneumatic atomizing administration device, which is characterized by comprising a liquid medicine box (1), an atomizing box (2) and a box cover (3), wherein a nozzle (4) is arranged on the lower part of an inner cavity of the liquid medicine box (1); an air inlet end of the nozzle (4) is connected with an air inlet guide pipe (5); an air outlet end of the nozzle (4) is inserted into a mixed flow pipe (6) on the lower part of the atomizing box (2) and is opposite to a slide block (7); the slide block (7) is arranged in the atomizing box (2) and a slide block cavity (8) on the upper part of the mixed flow pipe (6); the slide block cavity (8) is communicated with an inner cavity of the atomizing box (2); the upper part of the inner cavity of the atomizing box (2) is communicated with the inner cavity of the liquid medicine box (1); the upper part of the liquid medicine box (1) is connected with an atomized colloidal particle nozzle (9) which is communicated with the inner cavity of the liquid medicine box (1); the slide block (7) is connected with a regulating block (11) through a rigid connecting rod (10); and the regulating block (11) is arranged in a guide groove (12) on the liquid medicine box (1). Air or oxygen serving as atomizing power has no dependence on power supply, and the device has the advantages of small atomized liquid volume, small administration amount, high atomized medicine concentration and controlled atomized particles.

Description

technical field [0001] The invention relates to a medical device, especially a device for directly administering medicine to the respiratory tract without commercial power supply, in particular to a controllable colloidal particle for respiratory first aid that can be used in the field or under emergency conditions at the scene of a disaster. Type targeted pneumatic atomization drug delivery device. Background technique [0002] At present, whether in modern wars or sudden disasters, the proportion of burn injuries suffered by combatants or victims has always been relatively high, especially in the late stage of wounded treatment, and the final effect of treatment is the inhalation burn injury of the wounded respiratory system Inhalation burns of the respiratory system lead to respiratory congestion and edema affecting lung ventilation, alveolar wall degeneration leading to decreased gas exchange capacity in the lungs, adult respiratory distress syndrome (ARDS), respiratory...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing ultrasonic atomizer cannot be used in the field and under field conditions and cannot atomize suspensions and macromolecular compounds, thereby affecting the therapeutic effect. There is no dependence on power supply, the volume of the atomized liquid is small, the dosage of the drug is small, the concentration of the atomized drug is high, the size of the atomized particle is controllable, it can atomize a variety of drugs, the oxygen content in the atomized aerosol is high, the use is safe and reliable, adapt Colloidal particle controllable targeted pneumatic atomization drug delivery device for a wide range of occasions
