Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing ultrasonic nebulizer cannot be used in the field and under field conditions, and cannot atomize suspensions and macromolecular compounds, which affects the therapeutic effect and needs to find corresponding drugs for the symptoms, and affects the speed of medication. One that uses air or oxygen as the atomization power and has 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 particles is controllable, and the oxygen content in the atomized aerosol is high. Simple targeted pneumatic atomization drug delivery device that is safe and reliable, and can be pre-loaded with corresponding medical liquid according to different diseases.

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] like figure 1 , 2 , 3 shown.

[0034] A simple targeted pneumatic atomization drug delivery device with disposable pre-filled first aid liquid, all parts are made of medical plastic injection molding, such as figure 1 As shown, it includes a liquid medicine box 1, an atomization box 2, a mouthpiece 3 and an air inlet conduit 4. like image 3 As shown, the air intake conduit 4 is used to connect with the air source (a portable air source such as a miniature compressed air pump or an oxygen cylinder, etc.), and the atomization box 2 is screwed on the liquid medicine box 1 On the top, the mouthpiece 3 is set on the atomization box 2, and the two are pluggable and tightly fitted, not only required to be able to be inserted and removed, but also required to have a certain degree of sealing. 2, a connecting pipe 13 is specially designed to rea...

Abstract

The invention relates to a disposable simple targeting pneumatic atomizing administration device preloaded first-aid liquid medicine. The disposable simple targeting pneumatic atomizing administration device is characterized by comprising a liquid medicine box (1), an atomizing box (2) and a sucking device (3), wherein a guide sleeve (5) is arranged in the liquid medicine box (1) and is inserted into a diversion cover (7) in the atomizing box (2); a gap (8) in which the liquid medicine flows is formed between the guide sleeve (5) and the diversion cover (7); a spray pipe (6) is screwed in the guide sleeve (5); a push key (14) is arranged on the liquid medicine box (1); the air inlet end of the spray pipe (6) is connected with an air inlet guide pipe (4); an air spraying hole (9) is formed at the air outlet end of the spray pipe (6) and is opposite to the inlet end of a diversion hole (10) on the diversion cover (7); the outlet end of the diversion hole (10) is opposite to a baffle plate (11) in the atomizing box (2); the baffle plate (11) is connected with a fixed frame (16); and a medicinal bottle (17) preloaded with the first-aid liquid medicine is fixed on the fixed frame (16) and is positioned in the atomizing box (2). In the invention, air or oxygen is used as atomizing power, so the disposable simple targeting pneumatic atomizing administration device does not dependence on power supply, is small in volume of atomizing liquid, less in administration amount, high in concentration of atomized medicines and controllable in sizes of atomizing granules, and the troubles of medicine dispensing and medicine taking can be avoided.

Description

technical field [0001] The invention relates to a medical device, especially a respiratory drug delivery device that does not need a mains power supply, in particular a disposable prepackaged respiratory emergency medical device that can be used in the field or under emergency conditions at the scene of a disaster. A simple targeted pneumatic atomization drug delivery device for first aid liquid. 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 tra...
