Nebulizer system and heater device used in the nebulizer system

Abstract

The present invention provides a nebulizer system and a heater device suitable for the nebulizer system, which can facilitate the connection of a bottle, a heater device, and a nebulizer connector, and remove a discharge tube that is exposed to the outside and becomes an obstacle. The nebulizer system (1) comprises: a bottle (2) for storing liquid, which has a mouth part (25) on the upper part; a heater device (3), which can be connected with the mouth part (25); and a nebulizer connector (4 ), which can be connected to the heater device (3), the bottle (2) includes a dipping tube (22), which is immersed in the liquid stored inside the bottle (2), the upper end of the dipping tube (22) is The bottle mouth (25) is provided with a gap (226) communicating with the inside and outside of the bottle (2) and is arranged inside the peripheral wall of the bottle mouth (25), and the sprayer connector (4) includes: a nozzle member ( 42), having an injection port (421) for injecting gas; and an aerosol forming member (43), disposed at a position opposite to the injection port (421), utilizing the airflow of the gas ejected from the injection port (421) to pass through the impregnation The tube (22) and the heater device (3) suck the liquid in the bottle (2), and make the sucked liquid form a tiny aerosol, and the heater device (3) includes in its interior: the water guide tube (32) , one end of which is connected to the upper end of the dipping pipe (22), and the other end is connected to the aerosol forming member (43); the heating part (33), which heats the water guide pipe (32); and the discharge pipe (35) , one end of which is disposed opposite to the void (226), through which the other end allows the non-aerosolized liquid in the nebulizer connector (4) to flow back into the bottle (2).

Description

technical field [0001] The present invention relates to a nebulizer system for adding moisture (water vapor or mist water) to gas such as air or oxygen, and a heater device used in the nebulizer system. Background technique [0002] Conventionally, oxygen therapy for supplying oxygen to patients of the respiratory system has been performed, using oxygen nasal cannula, mask, etc., to supply the patient with, for example, oxygen generated from an oxygen cylinder, or oxygen concentrated by an oxygen concentrator made of an adsorbent such as molecular sieve. Since oxygen supplied from an oxygen cylinder or the like contains almost no moisture, it is necessary to prevent drying of the respiratory tract when supplying oxygen to the patient's nasal cavity and other respiratory tracts. Therefore, a humidifier is installed in the middle of the oxygen supply pipe to supply oxygen in a humidified state. [0003] In oxygen therapy, a nebulizer system is known as a humidifier used for h...

Problems solved by technology

[0008] As a structure for returning the liquid droplets accumulated in the nebulizer connector to the bottle, the nebulizer system has a discharge tube connecting the nebulizer connector and the bottle, but there is a possibility that human hands or objects are caught on the discharge tube provided outside the bottle, causing Problems with dumping the sprayer system

In addition, since the discharge tube is connected and fixed to the nebulizer connector, when the nebulizer connector is connected to the heater device and the bottle by screwing, the discharge tube becomes an obstacle, and there is a problem that the operability of the connection operation is extremely poor.

[0009] In addition, after connecting the nebulizer connector to the bottle or the heater unit, it is necessary to connect the discharge pipe to the bottle, and there is also a problem that the adjustment (setting) of the nebulizer connector is troublesome.

Also, when connecting the nebuliser connector to a heater unit or bottle, there is the possibility that the discharge tubing will come into contact with various objects in the patient room (human body or table, bed, wall, etc.), and if such contact occurs, it is necessary to maintain The front end of the clean discharge pipe becomes contaminated

When connecting such a contaminated discharge tube to the bottle, there is a problem that the liquid in the bottle will also be contaminated
