[0014] FIG. 1B is a bottom view of the heat stimulation instrument; and

[0015] FIG. 2 illustrates a heat stimulation instrument according to another example of the present disclosure.

DETAILED DESCRIPTION

[0016] An embodiment of a heat stimulation instrument according to the present disclosure will now be described in detail with reference to the drawings.

[0017] In an embodiment of the present disclosure, a heat stimulation instrument 10 includes a handle 100 provided with a vapor switch 102, and a body unit 110 that includes an electric heater 105, a vaporizing chamber 106, and a vapor chamber 109 in fluid communication with the vaporizing chamber 106 (See FIGS. 1A and 1B).

[0018] The handle 100 is provided with the vapor switch 102 and provided on top of the body unit 110. A user grips the handle 100, moves the body unit 110, and operates the vapor switch 102 to actuate an opening/closing-vapor chamber device 104 connected to a circuit board 103. The vapor switch 102 may be provided on any location on the handle 100.

[0019] The body unit 110 includes an electric heater 105, a vaporizing chamber 106, and a vapor chamber 109 in fluid communication with the vaporizing chamber 106, and is provided with a steam expelling port 108 extending from the vapor chamber 109 to the bottom surface of the body unit 110.

[0020] The vaporizing chamber 106 is provided adjacent to or near the electric heater 105 and is a space in which water introduced into the space is heated by the electric heater 105 into steam. A flow channel for introducing water is connected to the vaporizing chamber 106, and the vaporizing chamber 106 is in fluid communication with a dripping water flow channel 101 illustrated in FIG. 1A and a water reservoir (not illustrated). The water reservoir may be provided within the body unit 110.

[0021] The vapor chamber 109 is in fluid communication with the vaporizing chamber 106 and stores the steam formed in the vaporizing chamber 106.

[0022] Further, the steam expelling port 108 extending from the vapor chamber 109 to the bottom surface of the body unit 110 is provided and the vapor in the vapor chamber 109 is to be discharged from the bottom surface of the body unit 110. There may be provided a single steam expelling port 108 or a plurality of steam expelling ports 108. It is preferable to have a plurality of steam expelling ports 108 because a relatively large area can be heated simultaneously.

[0023] The steam is discharged when the vapor on/off device 104 is operated by the vapor switch 102. When an OPEN signal is transmitted from the vapor switch 102 to the circuit board 103, the opening/closing-vapor chamber device 104 is operated and the steam in the vapor chamber 109 is discharged from the steam expelling port 108.

[0024] In the embodiment of the present disclosure, the user provides heat stimulus to a subject site while pressing the body unit 110 against the site for pressurization. Although the pressure depends on the subject site, the heat stimulus may be provided while pressing is performed at a pressure on the order of, for example, 5 kPa to 15 kPa. A cushioning material such as a towel may be placed between the subject site and the body unit 110 when the body unit 110 is pressed against the subject site. Although depending on the subject site and its area for therapy delivery, the pressing may be performed several tens of times during the therapy delivery while pressing positions are being changed.

[0025] In pressing stimulation, the vapor is provided such that the temperature applied to the subject site is in a range of 35° C. to 60° C. through the cushioning material intervening therebetween. To provide the vapor, the temperature of the instrument bottom surface of the heat stimulation instrument 10 may be heated to 130° C. to 140° C.

[0026] In another embodiment of the present disclosure, a heat stimulation instrument 10 includes a handle 100 and an electric heater 105, and is capable of providing heat stimulus by applying heat and pressure to a subject site. They will now be summarized in this order (See FIG. 2).

[0027] The handle 100 is provided on top of a body unit 110, and a user grips the handle 100 and moves the body unit 110.

[0028] The body unit 110 includes an electric heater 105. The body unit 110 is to be heated by the electric heater 105 and heated at such a temperature that the temperature in a range of 35 to 60° C. is applied to the subject site. In the embodiment of the present disclosure, a practitioner delivers therapy by placing a cushioning material such as a towel between the electric heater 105 and the subject site. Although depending on the subject site, as with the case of the embodiment with vapor, several tens of times of heat stimulation may be provided during the therapy delivery while pressing is performed at a pressure on the order of, for example, 5 kPa to 15 kPa. A cushioning material such as a towel may be placed between the subject site and the body unit 110 when the body unit 110 is pressed against the subject site.

[0029] In the embodiments of the present disclosure, the heat stimulation instrument 10 can provide heat stimulus to any site of a human body subjected to therapy. For example, heat stimulus can be provided to a back, an abdomen, a flank, a shoulder, an arm, a lumbar part, and a leg. The heat stimulation instrument 10 not only applies heat stimulus to a surface, but also provides stimulus to a deep part of the human body. For example, the vagus nerve in the back can be activated by providing heat stimulus to the back. Further, the heat stimulation instrument 10 can be used not only in medical applications, but also in cosmetic and bodywork applications.

[0030] Results of heat stimulation treatments performed on subject sites by using the heat stimulation instrument according to the embodiment of the present disclosure will now be illustrated.

Example 1

[0031] Heat stimulation treatment was provided to a subject person (a woman in her 40s) who was suffering from flu symptoms and neck pain by using the heat stimulation instrument and performing several tens of times of pressing on her shoulder and back at a pressure on the order of 5 kPa to 15 kPa while generating vapor at a body unit temperature of 130 to 140° C. (subject site temperature 40° C.).

[0032] After the therapy delivery, her flu symptoms and neck pain were erased. In addition, after the therapy delivery compared with before the therapy delivery, reductions of −0.9 cm in her thigh, −0.5 cm in her calf, and −1.2 cm in her ankle were measured.

(subject site temperature 40° C.).

[0038] After therapy delivery, the excursion of his neck was improved. In addition, after the therapy delivery compared with before the therapy delivery, differences were found in anteflexion and postexion, and flexibility of his body was improved. The results are shown in Table 3.
