Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a spray for spraying a medicinal solution onto the skin of the human body.

(Prior Art) Sprays that have been sold to the public so far are sprayed by pointing the nozzle toward the skin and pushing the push handle.

In this case, depending on the distance between the injection port and the skin surface, the chemical solution often scatters and is wasted. There is also loss due to pushing the handle too much.

(Problem to be Solved by the Invention) This invention was made in view of the conventional situation, and enables concentrated spraying on the relevant skin surface and effective spraying by enlarging the pores.

[Structure of the device] (Example) To explain the following with reference to the embodiments shown in the drawings, in Fig. 1, 1 indicates a chemical solution formed by injecting a certain amount of a chemical solution into the interior and sealing high-pressure air in the space above the liquid surface. Tank body, 2 is a suction pipe 2a for the chemical solution in the tank body 1
and a chemical liquid injection pipe 2b facing outside of the tank body 1, and 3 is an operation handle portion associated with the injection system 2.

A small liquid reservoir space 4 communicating with the injection waterway 2d leading to the injection port 2c is provided in a portion of the chemical liquid jet pipe 2b facing into the tank body 1, and a female threaded portion 5 extends vertically across the liquid reservoir space 4. is provided.

The operating handle 3 is composed of a knob 6 and a screw shaft 7, and the tip of the screw shaft 7 is formed into a tube spiral 7a, and the side wall of the tube screw 7a is connected to the reservoir space 4. Three metering holes 8 facing each other are provided, and by adjusting the propulsion of the female screw portion 5 of the screw shaft portion 7, the number of metering holes 8 in the reservoir space 4 (1
It is possible to adjust the number of holes (from one hole to three holes).

Further, a bowl-shaped enclosure 12 made of a non-plastic material such as hard rubber is attached to the outside of the portion of the chemical liquid ejection pipe 2b facing outside the tank body 1, surrounding the injection port 2c.

In the drawings, 13 is a drug solution injection plug, and 14 is an air injection plug.

(Function) To use the human body spray having the above structure, hold the tank body 1 in one hand as shown in FIG. 3, and lightly press the bowl-shaped enclosure 12 against the skin surface of the human body.

Then, since the bowl-shaped envelope 12 is made of a non-plastic material, it is pressed against the skin surface just before the suction cup is suctioned, and some of the air inside the bowl-shaped envelope 12 escapes to the outside, creating a reduced pressure state. , and a bowl-shaped enclosure 12
Surface tension is generated on the skin surface surrounded by the pores, which forces the pores open.

Then, by turning the knob 6 of the operating handle 3 with the other hand, the number of holes (from one hole to three ). That is, when there is one, the injection pressure is weak, when there are two, it is medium, and when there are three, it is strong.

[Configuration of the device] The present invention is as described above, and since the skin surface is surrounded by the bowl-shaped enclosure 12, concentrated spraying is possible and no loss of the drug solution occurs, and the bowl-shaped enclosure 12 is crimped. Since the injection is performed from the injection port 10 under reduced pressure, the injection efficiency is good, and the absorption efficiency is improved because the injection is performed with the pores enlarged due to the surface tension generated on the skin surface of the bowl-shaped enclosure 12 due to the pressure bonding. can be increased.
