The present invention relates to a method of manufacturing a medical heater that can prevent deformation of the heater body that can be generated through the manufacturing process of the heater, and can significantly reduce the occurrence of defects such as poor coating of the heater.

In general, most medical warmers have a flat structure of mattresses, and their range of use is limited, and due to the large amount of external loss of heat released, intensive heat effects can be expected at the affected part of the human body or in the pain area requiring heating. There was no.

Accordingly, medical heaters are known in which the configuration of the heater body is formed in a semicircular shape to reduce the loss of heat emitted and maximize the use range of the heater body to be located at the necessary affected part of the human body.

The high frequency sound applied to the beacon 300 is a high frequency sound that is inaudible to the human ear and shoots a different signal in a business shop or installation space that operates a heater and the microphone of the operator's mobile terminal receives. An operator's mobile terminal, such as a unique high frequency sound stored in a smartphone, is interpreted by an app installed on the smartphone and sent to the server in a state where the signal is changed, and then the smartphone manages information about the internal air of the heater provided by the beacon and Temperature management information can be received and monitored.

Of course, the low-power Bluetooth method is difficult to distinguish inside and outside the store, but the high-frequency method to distinguish between inside and outside the store, there is an advantage that can prevent the leakage of personal privacy information.

Therefore, the beacon 300 communicates with a portable terminal of an operator operating a warmer and may be used for transmitting a user's temperature management information and internal air management information of the warmer to the portable terminal.

The beacon 300 may be applied on a Li-Fi basis according to the usage environment of the heater, which is an abbreviation of Light Fidelity, which transmits and receives data at a speed of 10 gigabytes per second using visible light emitted from an LED. Wireless communication technology is used, and the semiconductor in LED lighting can be used to transmit location information to a handheld terminal, such as a smartphone, of a heater operator.

Visible light communication is a communication technology that uses visible light to transmit information, and has a wavelength range of 380 to 780 nm and a frequency of 385 to 789 THz, and is 10,000 times wider than the total frequency of wireless communication.

Therefore, the visible light communication frequency is free of charge, and because it is common worldwide, it is inexpensive and has the advantage of providing more stable service.

In addition, since the frequency band is wide and there is no communication interference or collision phenomenon, security is also enhanced, and high speed communication is possible wherever there is lighting.

As described above, the beacon 300 transmits a specific ID signal when a smart phone user enters a signal reach distance from the beacon. The smartphone's Bluetooth device receives this signal and the app recognizes it and forwards it to the appropriate server. The server that receives the signal knows that a user has entered a certain location and can send information and service information set in the location to the user's smartphone through the beacon.

On the other hand, between the B) the heat insulation step and the C) the first attachment step may further include the step of attaching and punching the copper tape, the process for the step of attaching and punching the copper tape described above b) the heat insulation step And c) in the course of the first attachment step. The attaching and drilling steps of the copper tape are not specifically illustrated in the drawings, but reference may be made to FIGS. 10 to 12.

Attaching and drilling of the copper tape is an attachment portion of the planar heating element 140 and the copper tape 135 in a state in which the copper tape 135 is attached to the planar heating element 140 coated with silver paste as shown in FIG. 10. A process of applying a hole H along may be involved. Of course, the drilling hole (H) for the attachment portion of the planar heating element 140 and the copper tape 135 may use a perforator.

The silver paste may be, for example, a conductive resin composed of a mixture of silver powder, an acrylic resin, and a low boiling organic solvent. A conductive film is formed by evaporation of the organic solvent, and conductivity is generated. It can be cured in about 12 hours at room temperature. The silver paste has an effect of improving the adhesion between the planar heating element 140 and the copper tape 135 with excellent conductivity.

Through the punching step using the punching machine, a plurality of punching holes H may be formed at the attachment portion of the planar heating element 140 and the copper tape 135, and the punching holes H may be formed. Perforations are maintained at regular intervals, but the size of the perforation holes (H) is preferably in the range of 1 to 1.5 mm, which helps maintain the average temperature of the planar heating element 140, in particular the spacing between the perforations (H) At 10 mm, a relatively safe average temperature can be maintained. The size of the hole H and the gap between the hole H may reduce heat generation of the planar heating element and significantly reduce fire.
