Description

Technical Field

[0001] The utility model relates to a controller, in particular to a baby radiation warming table controller. Background Art

[0002] The existing baby warming tables are not intelligent enough, and there is a shortage of medical staff. As a result, even if the medical staff work in two shifts for 12 hours, they cannot monitor the situation of the baby warming tables. Once there are multiple babies who need extra attention at the same time, the medical staff will inevitably be unable to cope with the monitoring process, and serious medical accidents may occur.

[0003] At the same time, the existing baby warming table has a low safety level. Once the controller malfunctions, especially the malfunction of the automatic power-off function, the baby may be scalded. When the baby cries until medical staff arrive, they can only cut off the power by unplugging the plug. At this time, the baby has been scalded, which is a serious medical accident. Since there is no short circuit on the warming table as a whole, the air switch and fuse will not operate or blow. Utility Model Content

[0022] The program over-temperature monitoring and control module, the analog electronic over-temperature monitoring and control module and the mechanical over-temperature monitoring and control module all include fuses, which correspond to three fuses in the figure; when one or more temperature controls in the preheating module, the servo control module and the manual control module are abnormal, one or more fuses in the program over-temperature monitoring and control module, the analog electronic over-temperature monitoring and control module and the mechanical over-temperature monitoring and control module are blown.

[0023] The controller of the infant radiation warming table may further include an APGAR module, an alarm module, an expansion module, a temperature plate and a touch screen.

[0024] Expansion modules can be connected via RS232 interface;

[0025] The temperature board and the touch screen display the temperature independently, and the preheating module, servo control module and manual control module are controlled by the touch screen. The temperature board has no additional functions and will not freeze like the touch screen, and the interference is also small.

[0028] Preheating mode

[0029] A heating mode that maintains the mattress at a certain temperature; in this mode, the heater output is output according to a predetermined program.

[0030] Servo control mode

[0031] A mode of operation that achieves a temperature close to the user's set temperature; in this mode of operation, the power output automatically changes with the baby's temperature.

[0032] Manual control mode

[0033] A user-adjustable mode of operation in which the heater output is at a fixed level or at a fraction of maximum output.

[0034] The working principle of the skin temperature servo control method is defined as "baby temperature control"

[0035] This method is that the operator determines a baby's skin temperature value according to clinical medical requirements and the baby's physiological characteristics to set the temperature, and sticks the baby's skin temperature sensor on the baby's skin. The temperature inside the warming bed changes with the changes in the baby's skin temperature and the baby's skin temperature value determined by the operator. The skin temperature servo control is adjusted to stabilize the temperature inside the warming bed within a certain temperature range, thereby achieving the purpose of baby care.
