Description

[Detailed Description of the Invention] This invention relates to an improvement of a spray inhaler used to spray a medicinal liquid into a mist and administer it to the throat and oral cavity.

Conventionally, this type of atomized inhaler is equipped with a drug solution tank, and a drug mixing spoon is used to put the drug into this drug solution tank, but this spoon is not always provided in the atomization inhaler, so it has to be used every time it is used. For each use, the dispensing spoon must be retrieved from a storage location separate from the spray inhaler, which is complicated and inconvenient.

Focusing on this fact, this invention is designed to make it easier to use by always having a spoon for dispensing medicine, and to keep it hygienic without interfering with the use of the atomized inhaler. The aim is to provide a spray inhaler that can perform

Hereinafter, embodiments of this invention will be described based on the drawings.

First, in FIGS. 1 to 10 showing the first embodiment, 1 is a spray inhaler, which has a main body case 2.
and a chemical solution tank 3 which is detachably attached thereto. The main body case 2 is made of a synthetic resin material and is molded into a piston shape as a whole, and has a horizontal cylinder part 4 and a vertical cylinder part 5 integrally molded perpendicular to the horizontal cylinder part 4. An inner corner space formed by the front wall 5a of the vertical cylinder part 5 is defined as a tank mounting part 6.

A spray nozzle 8 is inserted into the nozzle holding cylinder 7 in the opening at the tip of the horizontal cylinder part 4 of the main body case 2, and behind the spray nozzle 8 there is an air pressure feeding mechanism 9 for feeding compressed air to the spray nozzle 8. Built-in. A vertical motor 10 serving as a driving source for the air pressure feeding mechanism 9 and a battery 11 serving as a power source for the motor 10 are built into the vertical cylinder portion 5 . The air pressure feeding mechanism 9 shown in the illustrated example employs a diaphragm pump, and includes a discharge valve 12 and a discharge valve 1 provided behind the spray nozzle 8.
A diaphragm 14 is installed behind both of the suction valves 13 provided below the motor 10, and the diaphragms 14 are reciprocated by the rotation of an eccentric cam 15 with a balancer directly connected to the shaft of the motor 10, thereby drawing air to the suction valves 13. The liquid is sucked into the diaphragm 14, discharged from the discharge valve 12, and sent under pressure to the spray nozzle 8. The suction valve 13 is communicated with an intake port 16 projecting from the side of the main body case 2.

Further, a liquid suction pipe 17 is provided on the lower surface 4a of the horizontal cylinder part 4 so as to hang down to the tank mounting part 6, and a suction port 18 at the upper end of this liquid suction pipe 17 is provided so as to face into the spray nozzle 8. , a liquid suction port 19 is provided at its lower end.

As shown in FIGS. 6 and 7, the liquid suction port 19 is molded from synthetic resin into a bottomed cylindrical shape that fits into the lower end of the liquid suction pipe 17, and the bottom wall 19a has 20 groups of small holes through which the chemical liquid passes. It is formed. The small holes 20 are formed by arranging a plurality of circular recesses 21 in a row on the same circle on the outer surface of the bottom wall 19a, and overlapping a part of the circumference of each of the circular recesses 21 at the center of the inner surface of the bottom wall 19a. It is formed by providing one circular recess 22 under such an arrangement and making the overlapping portion of the outer recess 21 and the inner recess 22 into a penetrating state. Contrary to the illustrated example, the small holes 20 groups can also be formed by providing a plurality of recesses 21 on the inner surface of the bottom wall 19a and one recess 22 on the outer surface of the bottom wall 19a. Since these 20 groups of small holes are processed at the same time by molding the liquid suction port 19 with synthetic resin, it is extremely easy and inexpensive to process compared to cloth or wire mesh filters used for conventional liquid suction ports. In addition, there is no need to take special consideration to unnecessary chemical reactions with the chemicals used, which tend to occur with conventional filters, increasing the degree of freedom in design.

The chemical liquid tank 3 is molded of synthetic resin into a square cylinder shape that matches the tank mounting part 6, and the lower surface 4 of the horizontal cylinder part 4
A liquid suction pipe 1 is attached to the upper surface wall 3a that is in contact with the
Chemical solution supply port 2 into which the liquid suction port 19 at the lower end of 7 is inserted.
