Detailed Description
The present application is described in further detail below in conjunction with figures 1-6.
The embodiment of the application discloses a temperature control module based on feedback adjustment. As shown in fig. 1 to 3, a temperature control module based on feedback adjustment includes a cooling unit 1 having a liquid inlet 11 and a liquid return 12, the cooling unit 1 is an ice blanket filled with cooling liquid, a heat conducting shell 2 is installed in the cooling unit 1, mercury is installed in the heat conducting shell 2, two ends of the heat conducting shell 2 are all open and are all embedded with adjusting seats 21 along the vertical direction in a sliding manner, one of the adjusting seats 21 is located at the liquid inlet 11, and the other adjusting seat 21 is located at the liquid return 12.
The medical staff can determine the initial position of the adjusting seat 21 by controlling the mercury amount contained in the heat conducting shell 2, so that the opening areas of the liquid inlet 11 and the liquid return 12 are in the designated size.
When external cooling liquid passes through a single pump and is fed to the liquid inlets 11 in a plurality of temperature control modules, the flow rate of the liquid inlet 11 with larger opening area in unit time is larger than the flow rate of the liquid inlet 11 with smaller opening area in unit time, so that the cooling effect of the temperature control module corresponding to the liquid inlet 11 with larger opening area is better.
Therefore, the medical staff can make the single pump send the cooling liquid to all the temperature control modules by controlling the mercury amount of the heat conduction shell 2 at the beginning, and the cooling effect of each temperature control module is different, so that the device is suitable for each part of the body of a patient, and the medical staff is not required to control the cooling effect of each temperature control module one by one through a plurality of pumps.
The two adjusting seats 21 are connected through the same connecting plate 22, so that the two adjusting seats 21 can synchronously lift; one of the adjusting seats 21 adjusts the size of the liquid inlet 11 in the sliding process, and the other adjusting seat 21 adjusts the size of the liquid return 12 in the sliding process.
During the use of the temperature control module, the patient will lie on the upper surface of the cooling unit 1, and the body of the patient will exchange heat with the cooling liquid through the cooling unit 1, so the temperature of the cooling liquid in the cooling unit 1 will be higher than the temperature of the cooling liquid which does not enter from the liquid inlet 11, and the body of the patient is in a state of sub-low temperature; medical staff can control the flow of the cooling liquid in unit time so that each part of the body of a patient is at a relatively stable temperature.
When the temperature control module cannot cool the part of the patient in time due to abnormal heating of the part, the temperature of the cooling liquid in the temperature control module below the part of the patient is raised, at the moment, heat in the cooling liquid is conducted into mercury through the heat conducting shell 2, the mercury is heated to expand and push the two adjusting seats 21 to synchronously move, so that the opening areas of the liquid inlet 11 and the liquid return 12 of the temperature control module are increased, and the opening areas of the liquid inlet 11 and the liquid return 12 of the rest temperature control modules are basically kept unchanged.
After medical staff adaptively increases the power of the pump, the flow rate of the cooling liquid entering the temperature control module with the increased opening areas of the liquid inlet 11 and the liquid return 12 in unit time is increased, so that the abnormal heating part of a patient can be quickly cooled, and the flow rate of the cooling liquid entering the other temperature control modules in unit time is basically unchanged; that is, in the process that the pump supplies liquid for all the temperature control modules, if the heating value of a certain part of a patient suddenly increases, medical staff can improve the refrigeration effect of the appointed temperature control module by increasing the power of the pump, so that the accurate cooling of each part of the patient is realized.
When the temperature of the cooling liquid in the temperature control module below a certain part of the patient is further reduced due to abnormal heating of the part of the patient, at the moment, heat in mercury is conducted into the cooling liquid through the heat conducting shell 2, the mercury contracts when encountering cold and pulls the two adjusting seats 21 to move synchronously, so that the opening areas of the liquid inlet 11 and the liquid return 12 of the temperature control module are reduced, and the opening areas of the liquid inlet 11 and the liquid return 12 of the other temperature control modules are basically kept unchanged.
After medical staff adaptively reduces the power of the pump, the flow of the cooling liquid entering the temperature control module with reduced opening areas of the liquid inlet 11 and the liquid return 12 in unit time is reduced, so that the heating abnormal part of a patient can be quickly heated, and the flow of the cooling liquid entering the other temperature control modules in unit time is basically unchanged; in the process that the pump supplies liquid for all the temperature control modules, if the heating value of a certain part of a patient suddenly decreases, medical staff can reduce the refrigeration effect of the designated temperature control module by reducing the power of the pump, so that the damage of the body of the patient due to the over-low temperature is avoided.
The liquid inlet 11 and the liquid return 12 are respectively arranged at the left end and the right end of the cooling unit 1 so as to ensure that the cooling liquid in the cooling unit 1 can circularly flow and ensure the cooling effect of the cooling liquid on the body of a patient.
The two ends of the heat conducting shell 2 are respectively extended to the left and right ends of the cooling unit 1, so that the heat conducting shell 2 has a larger surface area, and mercury in the heat conducting shell 2 exchanges heat with the cooling liquid through the heat conducting shell 2.
The heat conducting shell 2 is positioned at the bottom of the inner side of the cooling unit 1, so that the heat conducting shell 2 is at a certain distance from the body of the patient, and the direct influence of the body temperature of the patient on mercury is avoided as much as possible; at least one heat conduction column 23 positioned in the cooling unit 1 is arranged on the outer wall of the heat conduction shell 2, and one end of the heat conduction column 23 extends to the upper part of the inner side of the cooling unit 1 so as to ensure that cooling liquid can perform heat exchange with mercury better, thereby realizing accurate control of the opening areas of the liquid inlet 11 and the liquid return 12.
The heat conduction post 23 is equipped with many altogether, installs tray 24 on the heat conduction post 23, and tray 24 is located the top of cooling unit 1 inboard, and tray 24 can hold the patient through the top of cooling unit 1 to avoid the patient to flatten cooling unit 1 because of overweight, make heat conduction shell 2 crushed.
Two stop blocks 13 are arranged in the cooling unit 1, and the stop blocks 13 are in one-to-one correspondence with the adjusting seats 21 and are positioned above the adjusting seats 21. When mercury expands to make the adjusting seat 21 blocked by the baffle 13, the opening areas of the liquid inlet 11 and the liquid return 12 are in the maximum state, and the temperature control module achieves the optimal refrigeration effect, and the baffle 13 prevents the adjusting seat 21 from being separated from the heat conducting shell 2.
The implementation principle of the temperature control module based on feedback regulation in the embodiment of the application is as follows: when the temperature control module cannot cool the part of the patient in time due to abnormal heating of the part of the patient, the temperature of the cooling liquid in the temperature control module below the part of the patient is increased, so that mercury is heated to expand and push the two adjusting seats 21 to move synchronously, the opening areas of the liquid inlet 11 and the liquid return 12 of the temperature control module are increased, and the opening areas of the liquid inlet 11 and the liquid return 12 of the other temperature control modules are basically kept unchanged; after medical staff adaptively increases the power of the pump, the flow of the cooling liquid in the temperature control module with increased opening areas of the liquid inlet 11 and the liquid return 12 in unit time is increased, so that the abnormal heating part of the patient can be quickly cooled, and the flow of the cooling liquid in the rest temperature control modules in unit time is basically unchanged, thereby realizing accurate cooling of each part of the patient.
When the temperature of the cooling liquid in the temperature control module below a certain part of the patient is further reduced due to abnormal heating of the part of the patient, the temperature of the cooling liquid in the temperature control module below the part of the patient is reduced, so that mercury contracts when encountering cold and pulls the two adjusting seats 21 to move synchronously, the opening areas of the liquid inlet 11 and the liquid return 12 of the temperature control module are reduced, and the opening areas of the liquid inlet 11 and the liquid return 12 of the rest temperature control modules are basically kept unchanged; after medical staff adaptively reduces the power of the pump, the flow of the cooling liquid in the temperature control module with reduced opening areas of the liquid inlet 11 and the liquid return 12 in unit time is reduced, so that the heating abnormal part of a patient can be quickly heated, the flow of the cooling liquid in the rest temperature control modules in unit time is basically unchanged, and the damage of the body of the patient due to the too low temperature is avoided.
The embodiment of the application also discloses temperature control equipment based on feedback adjustment. As shown in fig. 4 to 6, a temperature control device based on feedback adjustment includes a cooler 3 and at least two groups of temperature control modules based on feedback adjustment, wherein a liquid inlet pipe 31 and a liquid return pipe 32 are installed on the cooler 3, the liquid inlet pipe 31 is communicated with all liquid inlet ports 11, and the liquid return pipe 32 is communicated with all liquid return ports 12; a temperature sensor 14 is installed in the cooling unit 1, and the temperature sensor 14 is coupled to the cooler 3.
When the patient is undergoing sub-cryogenic treatment, the medical staff will preset the temperature required by each temperature control module via the chiller 3 and the temperature sensor 14 will monitor the temperature of the coolant in the cooling unit 1 in real time.
When the value detected by the temperature sensor 14 is greater than the temperature set by the cooler 3, the temperature sensor 14 will emit a cooling signal to the cooler 3, the cooler 3 will control the pump in the cooler to increase the power, so that the cooling liquid flow rate in the liquid inlet pipe 31 will increase, and the cooling liquid flow rate in the temperature control module corresponding to the part to be cooled in time will increase in unit time, so that the part of the patient can be cooled automatically in time; while the flow of coolant into the remaining temperature control modules will be substantially unchanged for a unit of time so that the rest of the patient remains at the prescribed temperature.
When the value detected by the temperature sensor 14 is equal to the temperature set by the cooler 3, the power of the cooler 3 is unchanged, and the flow rate of the cooling liquid entering the temperature control module in unit time is basically unchanged, so that each part of the patient is still kept at the designated temperature.
When the value detected by the temperature sensor 14 is smaller than the temperature set by the cooler 3, the temperature sensor 14 will emit a heating signal to the cooler 3, the cooler 3 will control the pump therein to reduce the power, so that the flow rate of the cooling liquid in the liquid inlet pipe 31 is reduced, and the flow rate of the cooling liquid entering the temperature control module corresponding to the part to be heated in time in unit time is reduced, so that the part of the patient can be heated automatically in time; while the flow of coolant into the remaining temperature control modules will be substantially unchanged for a unit of time so that the rest of the patient remains at the prescribed temperature.
It should be noted that, the thermal expansion of mercury changes linearly, the difference between the value detected by the temperature sensor 14 and the set temperature of the cooler 3 is in direct proportion to the power change value of the cooler 3, and the flow change value in unit time after the opening areas of the liquid inlet 11 and the liquid return 12 change is equal to the flow change value in unit time of the liquid inlet pipe 31, so that the cooling effect of each group of temperature control modules is accurately controlled.
The cooling units 1 are provided with four groups in total and are sequentially arranged along a straight line, the first group of cooling units 1 corresponds to the head and the neck, the second group of cooling units 1 corresponds to the back and the arms, the third group of cooling units 1 corresponds to the buttocks and the palms, and the fourth group of cooling units 1 corresponds to the legs and the feet, so that the partition cooling of each part of a patient is realized.
The implementation principle of the temperature control equipment based on feedback regulation in the embodiment of the application is as follows: when one or more parts of the patient need to be cooled in time, the temperature sensor 14 controls the cooling liquid flow rate in the liquid inlet pipe 31 to be increased through the cooler 3 after detecting the temperature rise, and the cooling liquid flow rate in the temperature control module corresponding to the part needing to be cooled in time is increased in unit time, so that the part of the patient can be cooled in time automatically; while the flow of coolant into the remaining temperature control modules will be substantially unchanged for a unit of time so that the rest of the patient remains at the prescribed temperature.
When the value detected by the temperature sensor 14 is equal to the temperature set by the cooler 3, the power of the cooler 3 is unchanged, and the flow rate of the cooling liquid entering the temperature control module in unit time is basically unchanged, so that each part of the patient is still kept at the designated temperature.
When one or more parts of the patient need to be heated in time, the temperature sensor 14 controls the flow rate of the cooling liquid in the liquid inlet pipe 31 to be reduced through the cooler 3 after detecting the temperature reduction, and the flow rate of the cooling liquid in the temperature control module corresponding to the part needing to be heated in time in unit time is reduced, so that the part of the patient can be heated automatically in time; while the flow of coolant into the remaining temperature control modules will be substantially unchanged for a unit of time so that the rest of the patient remains at the prescribed temperature.
In summary, by controlling the mercury amount contained in the heat conducting shell 2 at the beginning, the medical staff can make the refrigerating effect of each temperature control module different when a single pump conveys the cooling liquid to all the temperature control modules; when the temperature of one or more parts of a patient is changed accidentally, the temperature control module can control the temperature of the part of the parts in time, and the temperature of the rest parts is kept unchanged, so that the temperature of each region can be adaptively adjusted according to temperature feedback.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
