Description

[Detailed description of the invention] This invention relates to an improvement of a drug inhalation device that sprays and inhales a drug into the bronchus or oral cavity, and its purpose is to supply a suitable atomized drug solution. Let us propose a drug inhalation device that can quickly start spraying after turning on the switch, has good thermal efficiency, has a simple structure, is easy to manufacture, and can be provided at a low price. That is.

Conventional devices of this type have separate chemical liquid tanks and water tanks, heat a certain amount of water to generate steam, mix the chemical with this steam, and eject it. Since the spraying was performed only after the process was completed, a large amount of heat was required, and the structure was complicated and expensive.

This invention solves the drawbacks of the above-mentioned conventional example, and its structure will be explained below with reference to the drawings shown as embodiments.

Reference numeral 1 denotes a main body case, on the outside of which a chemical tank 2 is attached.

This chemical solution tank 2 contains a drug solution 3 of an appropriate concentration, which is a drug diluted with water.

It is desirable that the main body case 1 and the chemical solution tank 2 have an easy-to-grip shape for convenient carrying.Furthermore, the chemical solution tank 2 can be implemented as a disposable cartridge type, or as a refill type for the chemical solution 3. is possible.

It should be noted that various drugs that can be used here include bronchodilators, asthma treatment agents, mouthwashes for oropharyngeal diseases, and anti-inflammatory and disinfectant mouthwatering agents.

A motor 4 is built in a part of the main body case 1, and a pump 5 which is driven by the motor 4 is provided.

The pump 5 communicates with the inside of the chemical liquid tank 2 via a tube 6 or the like, and pressurizes the chemical liquid 3 and sends it forward.

A ring-shaped heater 7 and a nozzle 8 are installed at the front of the pump 5.
are arranged.

Therefore, in the illustrated embodiment, the chemical solution 3 is first applied to the heater 7.
After being heated, the atomized chemical liquid 9 is sprayed from the nozzle 8.

The temperature of the atomized chemical liquid 9 is determined by the heating state of the heater 7.

Further, since the ring-shaped heater 7 is used, the thermal efficiency is good, and the chemical solution can be instantly heated and spraying can be started quickly.

A nozzle cover 10 preferably covers the nozzle 8 at the front end of the main body case 1 and scatters the atomized chemical liquid 9 in a necessary range.

Further, it is desirable that the nozzle cover 10 be configured to be detachably attached.

In addition, the positions of the heater 7 and the nozzle 8 are reversed from the above, and the chemical solution 3 is first atomized as the atomized chemical solution 9 by the nozzle 8, and immediately after that, the heater 7 provided in the nozzle cover 10 is heated to an appropriate temperature. It is also possible to implement it as

Reference numeral 11 in the figure is a cord provided to electrically connect the heater 7 and the motor 4.

In the embodiment shown in FIG. 1, a main body case 1 is placed on a chemical liquid tank 2, and a chemical liquid is pumped through a tube 6 by a pump 5.
It was designed to pump up water.

In the embodiment shown in FIG. 2, a chemical liquid tank 2 is placed on a main body case 1 and legs 12 are provided below the main body case 1. In this case, an inlet 13 for a chemical liquid 3 is placed on a main body case 1. Since it is provided on the lower side, the structure must be perfect to prevent the chemical solution 3 from leaking.

Note that it is also possible to implement a structure in which the injection port 13 is not formed on the lower side of the chemical liquid tank 2, but is opened at the upper side, and the chemical liquid 3 is piped from above the chemical liquid tank 2 to the pump 5.

Furthermore, in this case, when replenishing the chemical solution 3, the chemical solution tank 2
Since it is necessary to remove the liquid from the main body case 1, which is time-consuming, it is desirable to provide a liquid supply port with a cap 14 in a part of the chemical liquid tank 2.

This invention has the above-mentioned configuration, and therefore,
There is no need to wait for steam generation as in conventional models, and spraying can be started quickly. Furthermore, it has good thermal efficiency and is easy to adjust temperature, and its simple structure makes it easy to manufacture and inexpensive. The drug inhaler of this invention has excellent practical effects.
