When the invention is used, a patient is horizontally placed on the bed body 1, the rotating handle 22 is rotated according to the body type of the patient, the rotating handle 22 rotates the second lead screw 19, the second lead screw 19 rotates under the matching with the threaded hole on the moving rod 21, so that the moving rod 21 moves to the upper part of the mammary gland of the patient, the servo motor switch 7 controls the servo motor 12 to work, the servo motor 12 works to drive the first lead screw 9 to rotate, the first lead screw 9 rotates under the matching with the threaded hole 17 on the middle moving block 13, so that the middle moving block 13 moves downwards on the first lead screw 9, meanwhile, the middle moving block 13 drives the lateral moving block 15 to move downwards on the guide column 11, the arrangement of the guide column 11 and the lateral moving block 15 can improve the stability during movement, the middle moving block 13 moves downwards to drive the cross beam 16 to move downwards, when the cover body 24 on the warming device 23 contacts the mammary gland of the patient, the pressure sensor 26 collects pressure signals, the pressure sensor 26 transmits the acquired pressure signal to the PLC controller 6, after the PLC controller 6 receives the signal, the output end of the PLC controller 6 sends an instruction to the servo motor switch 7 to control the servo motor switch 7 to be powered off, then the heating switch 8 controls the heating wire 28 to work, the heating wire 28 works to heat the liquid in the liquid storage layer 27, when the temperature sensor 29 in the liquid storage layer 27 acquires the temperature in the liquid storage layer 27 and transmits the temperature to the PLC controller 6, the temperature is compared with the temperature range of 25-35 ℃ pre-transmitted in the PLC controller 6, if the temperature is in the range, the output end of the PLC controller 6 sends an instruction to control the heating switch 8 to be turned off, if the temperature is in the range, the output end of the PLC controller 6 sends an instruction to control the heating switch 8 to work to continue heating, the temperature in the liquid storage layer 27 is transmitted to the sterilization layer 25, and the sterilization layer 25 is used for warm nursing of the mammary gland of a patient, promote blood circulation of the affected part of the mammary gland, help the patient to be recovered, and the heater strip 28 has better physical strength, also has longer life simultaneously.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
