ッドを提供することを目的とする。In the shower head having the above-mentioned drug sustained release function, air mixed in the cartridge expands and contracts due to pressure fluctuation inside the cartridge due to the start and stop of the use of the shower. There is a problem that the drug in the cartridge may be excessively released. Further, when the cartridge is formed of a soft material, the cartridge expands and contracts due to pressure fluctuation inside the cartridge due to the start and stop of use of the shower, or the user is mounted outside the shower head. There is a problem that the cartridge contracts by applying pressure to the cartridge, and the medicine in the cartridge may be excessively released. The present invention has been made in view of the above-mentioned problems, and there is no possibility that a drug is excessively released from a cartridge filled with a drug into running water during use of a shower, and the drug can be stably placed in running water. It is an object of the present invention to provide a shower head with a drug sustained release function, which assures sustained release and prevents the drug from flowing out of the cartridge when the shower is not used.

Abuts against the valve body of the valve member to close the opening of the drug sustained release cartridge by the valve body, thereby preventing the drug from flowing out of the drug sustained release cartridge. When the shower is used, i.e., when the shower head is passed through, the medicine sustained release cartridge moves downstream against the urging force of the urging means due to the water pressure of the water flowing through the opening of the valve member. The end is separated from the valve body of the valve member, and the opening of the drug sustained release cartridge is opened. From the water passage of the shower head, water penetrates into the drug sustained release cartridge through the opening of the drug sustained release cartridge, and the water-soluble liquid drug or the saturated aqueous solution of the water-soluble drug in the drug sustained release cartridge is Through the opening,
Discharged into the water channel of the shower head. The opening of the drug sustained release cartridge is covered with a porous membrane, and there is no air whose volume changes due to pressure fluctuations in the drug sustained release cartridge. Therefore, the flow of the water and the water-soluble liquid drug or the saturated aqueous solution of the water-soluble drug in the drug sustained release cartridge is stabilized. As a result, the water-soluble liquid drug or the saturated aqueous solution of the water-soluble drug in the drug sustained-release cartridge is gradually released into the water flowing through the water passage of the shower head without being excessively released during use of the shower. Released.

Semilunar engage the opening 4b 1, 4b 2 of, the valve body 4a of the valve member 4 through the opening 9a of the guide member 9, the cover 8b of sustained drug release cartridge 8 in contact with, the opening of the cover 8b 8
It closes the b 1. As a result, when the shower is not used, the outflow of ascorbic acid from the drug sustained release cartridge 8 is prevented. When the shower is used, that is, when the water flows through the shower head for a bath with the drug sustained release function, the water pressure of the tap water flowing through the openings 4b 1 and 4b 2 of the valve member 4, as shown in the right half of FIGS. As a result, the medicine sustained release cartridge 8 moves downstream against the urging force of the coil spring 7, and the distal ends of the legs 9 d 1 and 9 d 2 of the guide member 9 are connected to the semilunar openings 4 b 1 and 4 b 2 of the valve member 4. engages, away from the valve body 4a of the cover 8b valve member 4 of the sustained drug release cartridge 8, the opening 8b 1 of sustained drug release cartridge 8 is opened. As shown by the arrow in the right half of FIGS.
Tap water that has passed through the openings 4b 1 and 4b 2 is guided by the legs 9d 1 and 9d 2 and the slopes 9c 1 and 9c 2 of the guide member 9 and flows toward the opening 9a. Some reach tap water to the opening 9a, through the opening 9a and the opening 8b 1, flows into the drug sustained-release cartridge 8, the remaining portion, the drug sustained-release cartridge 8 through the groove 9b and passing It flows into the annular gap between the water channel wall.

Since b 1 is covered by a porous membrane 8c, tap water gradually flows into sustained drug release cartridge 8. As a result, the flow of the tap water and the saturated aqueous solution of ascorbic acid in the drug sustained release cartridge 8 is stabilized. Since there is no air whose volume changes due to pressure fluctuations in the drug release cartridge 8, the flow of tap water and the saturated aqueous solution of ascorbic acid in the drug release cartridge 8 is stabilized. Since the drug sustained release cartridge 8 is formed of a hard material and does not deform due to a difference in internal and external pressures, the flow of tap water and a saturated aqueous solution of ascorbic acid in the drug sustained release cartridge 8 is stabilized. As a result, the ascorbic acid saturated aqueous solution in the drug sustained release cartridge 8 is not excessively released during use of the shower, and the guide member 9 is not released.
And is gradually and stably released into tap water passing through the groove 9b.

The cartridge moves to the upstream side, and the end of the cartridge contacts the valve body of the valve member to close the opening of the drug sustained release cartridge by the valve body, thereby preventing the drug from flowing out of the drug sustained release cartridge. When the shower is used, i.e., when the shower head is passed through, the medicine sustained release cartridge moves downstream against the urging force of the urging means due to the water pressure of the water flowing through the opening of the valve member. The end is separated from the valve body of the valve member, and the opening of the drug sustained release cartridge is opened. From the water passage of the shower head, water penetrates into the drug sustained release cartridge through the opening of the drug sustained release cartridge, and the water-soluble liquid drug or the saturated aqueous solution of the water-soluble drug in the drug sustained release cartridge is Through the opening, it is discharged to the water passage of the shower head. The opening of the drug sustained release cartridge is covered with a porous membrane, and there is no air whose volume changes due to pressure fluctuations in the drug sustained release cartridge. Therefore, the flow of the water and the water-soluble liquid drug or the saturated aqueous solution of the water-soluble drug in the drug sustained release cartridge is stabilized. As a result, the water-soluble liquid drug or the saturated aqueous solution of the water-soluble drug in the drug sustained-release cartridge is gradually released into the water flowing through the water passage of the shower head without being excessively released during use of the shower. Released.
