A: An organic erectile dysfunction treatment device, comprising: an implant portion (10) used for being placed within the penis of a male patient; a driving apparatus (20) connected to the implant portion (10) and used for changing the operation state of the implant portion (10); and a sensing terminal (30) which is in signal connection with the driving apparatus (20) and used for sensing behavior information for the male patient to match a preset rule, so that the driving apparatus (20) changes the operation state of the implant portion (10) according to the behavior information. According to the device, the behavior information of the male patient is sensed by means of the sensing terminal (30), and the driving apparatus (20) changes the operation state of the implant portion (10) placed in the penis of the male patient when the behavior information matches the preset rule, so that the patient can achieve the control of the operation state of the implant portion (10) by completing the specific behavior, and it is very convenient to use the device.
B: A head structure of an applicator, comprising a sleeve cylinder (30), an applying head (10), a fixture (20), and a fixed base (40). The sleeve cylinder (30) is hollow and comprises a first connecting part (31) and a second connecting part (32). The applying head (10) is provided therein with a through hole (11) and comprises a head part (12) and an annular tail part (13). The fixture (20) comprises a bottom part (21) and at least a pair of symmetric and flexible toothed fittings (22) connected to the bottom part (21). The annular tail part (13) of the applying head (10) is arranged between the toothed fittings (22). The toothed fittings (22) are capable of clamping the applying head (10). The bottom part (21) of the fixture (20) is fixedly connected to the first connecting part (31) of the sleeve cylinder (30). The fixed base (40) comprises a base (41) and a hollow fixed rod (42) connected to the base (41). The base (41) of the fixed base (40) is fixedly connected to the second connecting part (32) of the sleeve cylinder (30). One extremity of the fixed rod (42) is inserted into the through hole (11) of the applying head (10) and in communication with the through hole (11); the other extremity is in communication with the external environment. The head structure is simple, has strong practicability, is easy to carry, and can be used repeatedly.
C: Underpants with male physiological characteristics comprise an underpants body (10), a first protruding portion (11) for accommodating a penis, and a second protruding portion (12) for accommodating testis. The first protruding portion (11) and the second protruding portion (12) are disposed on the underpants body (10). The first protruding portion (11) accommodates the penis, and the second protruding portion (12) accommodates the testis, so as to protect two male physiological characteristics separately. The underpants have a reasonable shape, are adaptable to male physiological characteristics, facilitate normal physiological development of adolescents, and also have health care effects on a reproductive system of an adult.
D: Period underwear with a temperature sensing patch. The period underwear with a temperature sensing patch comprises a period underwear body (1), wherein a pad (2) is provided at a crotch portion (102) of the period underwear body (1); the period underwear body (1) comprises an outer non-woven fabric layer (10) and an inner non-woven fabric layer (20), a surface of the outer non-woven fabric layer (10) being coated with a thermally conductive ink strip (5); a temperature sensing patch (4) is provided at a position, corresponding to a female&#39;s uterus, of the period underwear body (1); the temperature sensing patch (4) comprises a first air-impermeable film layer (41), a dust-free paper layer (43) and a second air-impermeable film layer (42); the first air-impermeable film layer (41) is bonded to the outer non-woven fabric layer (10); a peripheral edge of the second air-impermeable film layer (42) is bonded to the first air-impermeable film layer (41), an interlayer is formed between the first air-impermeable film layer (41) and the second air-impermeable film layer (42), the dust-free paper layer (43) is provided in the interlayer, and a self-heating material (44) is distributed on the dust-free paper layer (43); a plurality of air-permeable areas (401) are provided on the second air-impermeable film layer (42), and air permeable holes (46) are provided in each air permeable area (401); and a third air-impermeable film layer (45) is bonded to each air-permeable area (401).
