Description

Technical Field

[0001] This invention relates to the field of temperature monitoring and regulation, and in particular to a temperature control system for cardiac surgical care. Background Technology

[0002] Cardiac surgery, due to factors such as anesthesia, cardiopulmonary bypass, and prolonged exposure time, can easily lead to hypothermia. Hypothermia can have numerous adverse effects on a patient's coagulation function, cardiovascular stability, wound healing, and immune function. Mild cases manifest as chills, increased oxygen consumption, and exacerbated incision pain; severe cases can induce arrhythmias, myocardial ischemia, coagulation disorders, and even multiple organ failure. Therefore, timely and precise rewarming after surgery is a crucial step in preventing serious complications, protecting organ function, and promoting successful recovery.

[0003] Currently, the commonly used rewarming methods in clinical practice mainly include passive rewarming and active rewarming. Passive rewarming includes covering the patient with a blanket or raising the room temperature, but it is slow and ineffective. Active rewarming includes using a warming blanket, which improves the rewarming speed, but requires manually setting rewarming parameters, which cannot be dynamically adjusted according to the patient's individual differences and real-time physiological state.

[0004] While some improvements have been made to address the shortcomings of existing active rewarming methods, such as the YCB-7000 inflatable body temperature rise system, these technologies only monitor the patient's core body temperature and neglect physiological indicators closely related to rewarming effectiveness, such as heart rate and blood pressure. This incomplete monitoring of physiological data makes it difficult for medical staff to fully understand the patient's physiological state during the rewarming process and to make accurate clinical decisions. Summary of the Invention

[0005] To address the technical problem of existing technologies where postoperative active rewarming monitoring data is limited and cannot achieve accurate and stable rewarming, the present invention proposes a temperature control system for cardiac surgery nursing, comprising a data processing module, a temperature control module, and a vital signs monitoring module, wherein the data processing module is communicatively connected to the temperature control module and the vital signs monitoring module, respectively.

[0006] The vital signs monitoring module includes a core temperature sensor, a skin temperature sensor, and an electrocardiogram monitor.

[0007] The temperature control module includes a heated mattress, a side heating unit, a top heating unit, and a bottom heating unit. The heated mattress, the side heating unit, the top heating unit, and the bottom heating unit form a heating chamber during reheating. The side heating unit, the top heating unit, and the bottom heating unit each include multiple mounting holes. The heating module is installed in the mounting holes through a sealing ring.

[0008] A first monitoring component and a second monitoring component are arranged sequentially from top to bottom on the inner side of the side heating unit. The first monitoring component includes a first electrically controlled telescopic rod arranged symmetrically and a first monitoring plate arranged between the first electrically controlled telescopic rods. The second monitoring component includes a second electrically controlled telescopic rod arranged symmetrically and a second monitoring plate arranged between the second electrically controlled telescopic rods. Multiple ultrasonic ranging sensors and multiple temperature sensors are alternately arranged at equal intervals on the second monitoring plate, and multiple temperature sensors are arranged at equal intervals on the first monitoring plate.

[0009] Furthermore, the heated mattress body is provided with multiple heating chambers arranged in a matrix, each heating chamber is provided with a silicone heating pad, each silicone heating pad is independently temperature controlled, the upper surface of the body is provided with a placement groove, the placement groove is provided with a breathable pad, the side of the heated mattress is provided with a mattress control unit, the mattress control unit controls each silicone heating pad, and the mattress control unit communicates with the data processing module through wireless communication.

[0010] Furthermore, the side heating units are fixedly installed on the left and right sides of the hospital bed, located on both sides of the heated mattress, the top heating unit is rotatably connected to the top of the side heating units, and the bottom heating unit is rotatably installed at the bottom of the hospital bed.

[0011] Furthermore, when not in use, the top heating unit and the bottom heating unit are flipped away from the bed. After the flipping, the angle between the top heating unit and the side heating unit is less than 30°. The top heating unit is located on the side of the side heating unit away from the bed, and the bottom heating unit is in a horizontal position. When the patient is in position, the top heating unit and the bottom heating unit are flipped towards the bed. After the flipping, the top heating unit and the side heating unit are perpendicular to each other. The top heating unit is located above the heated mattress. The two top heating units form the top heating surface, and the bottom heating unit is connected to the left and right side heating units respectively through a locking structure to form a heating cavity.

[0012] Furthermore, the side heating unit, the top heating unit, and the bottom heating unit are solid structures made of heat-insulating material.

[0013] Furthermore, in the side heating unit, the top heating unit, and the bottom heating unit, the mounting through holes are arranged at equal intervals along the long side, and the short sides on both sides are a first distance away from the adjacent mounting through holes.

[0014] Furthermore, the heating module includes a housing, the right side of which is made of a thermally conductive material, and the rest of the housing is made of a thermally insulating material. During installation, the right side of the housing is located inside the side heating unit, the top heating unit, and the bottom heating unit. A control circuit is provided on the left side of the housing, and the control circuit communicates with the data processing module wirelessly.

[0015] Furthermore, the left side interior of the housing is provided with a first ventilation component, a heating element and a second ventilation component from top to bottom. The first ventilation component includes a first vent hole penetrating the left side of the housing, and a first micro solenoid valve and a first micro fan are disposed inside the first vent hole. The second ventilation component includes a second vent hole penetrating the left side of the housing, and a second micro solenoid valve and a second micro fan are disposed inside the second vent hole.

[0016] Furthermore, the second monitoring plate is 15cm away from the heated mattress, and the first monitoring plate and the second monitoring plate are 10cm apart.

[0017] Furthermore, the feature is that: the data processing module receives instructions, starts the heated mattress and each heating module, heats the patient according to preset control parameters, and rewarms at a rate of 0.5℃ / hour. Based on the data from the vital signs monitoring module, the rewarming process is monitored in real time. When the patient's core body temperature reaches the preset target body temperature and the physiological indicators are normal, the heated mattress and each heating module are controlled to maintain a constant body temperature, enter the constant temperature maintenance mode, and start timing. When the timing reaches the set time, the rewarming process is stopped, and the data of the entire rewarming process is recorded.

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0028] like Figure 1 As shown, the temperature control system for cardiac surgery nursing proposed in this invention includes a data processing module, a temperature control module, and a vital signs monitoring module. The data processing module is communicatively connected to the temperature control module and the vital signs monitoring module, respectively.

[0029] The vital signs monitoring module includes a core temperature sensor, a skin temperature sensor, and an electrocardiogram (ECG) monitor to monitor the patient's physiological indicators during rewarming. Core temperature during rewarming refers to the temperature of vital organs deep within the body, typically represented by blood or internal organ temperature. This physiological indicator accurately reflects the physiological state of critical organs such as the brain and heart, and is a crucial monitoring parameter for postoperative life support. In this invention, a rectal temperature sensor, specifically the YSI 400 series, is used as the core temperature sensor. The skin temperature sensor includes disposable surface temperature probes placed on the patient's chest, abdomen, and limbs. The MC-EB12 disposable surface temperature probe is specifically selected to monitor skin surface temperature and reflect the peripheral circulation status. The ECG monitor monitors the patient's heart rate, blood oxygen saturation, and blood pressure, reflecting the stability of the recovery process and identifying potential complications.

[0030] like Figure 2 and Figure 3As shown, the temperature control module includes a heated mattress 1, a side heating unit 2, a top heating unit 3, and a bottom heating unit 4. The heated mattress 1, the side heating unit 2, the top heating unit 3, and the bottom heating unit 4 can form a heating chamber.

[0031] The heated mattress 1 has multiple heating chambers arranged in a matrix within its body, enabling zoned heating. Each heating chamber contains a silicone heating pad, and each silicone heating pad has independent temperature control. A placement slot is provided on the upper surface of the body, and a breathable pad is placed within the slot. A mattress control unit is located on the side of the heated mattress 1. The mattress control unit controls each silicone heating pad and communicates with a data processing module wirelessly.

[0032] Side heating units 2 are fixedly installed on the left and right sides of the hospital bed, located on both sides of the heated mattress 1. Top heating unit 3 is rotatably connected to the top of side heating unit 2, and bottom heating unit 4 is rotatably installed at the bottom of the hospital bed. When not in use, top heating unit 3 and bottom heating unit 4 are flipped away from the hospital bed. After flipping, the angle between top heating unit 3 and side heating unit 2 is less than 30°. Top heating unit 3 is located on the side of side heating unit 2 away from the hospital bed, and bottom heating unit 4 is in a horizontal state to facilitate patient movement. When the patient is in position, top heating unit 3 and bottom heating unit 4 are flipped towards the hospital bed. After flipping, top heating unit 3 and side heating unit 2 are perpendicular to each other. Top heating unit 3 is located above heated mattress 1. The two top heating units form the top heating surface. Bottom heating unit 4 is connected to the left and right side heating units respectively through a locking structure (not shown in the figure) to form a heating cavity. The locking structure can adopt conventional designs in the prior art according to actual connection requirements.

[0033] The side heating unit 2, top heating unit 3, and bottom heating unit 4 are solid structures made of heat-insulating material. The heat-insulating material is polyetherimide, a solid material. Each of the side heating unit 2, top heating unit 3, and bottom heating unit 4 includes multiple mounting through holes 5. The heating module 6 is mounted to the mounting through holes 5 via sealing rings. Figure 3 As shown, the mounting through holes 5 are arranged at equal intervals along the long side of the side heating unit 2 or the top heating unit 3. The short sides of the side heating unit 2 or the top heating unit 3 are 10cm away from the adjacent mounting through holes 5. The mounting through holes 5 in the bottom heating unit 4 have the same arrangement.

[0034] like Figure 4As shown, the heating module 6 includes a housing 61. The right side of the housing 61 is made of a thermally conductive material, specifically copper. The remaining parts of the housing 61 are made of a thermally insulating material, specifically polyetherimide, which is a solid material. During installation, the right side of the housing 61 is located inside the side heating unit 2, the top heating unit 3, and the bottom heating unit 4 to facilitate heat release. A control circuit 69 is located on the outside of the left side of the housing 61. The control circuit 69 communicates with the data processing module wirelessly. Inside the left side of the housing 61, from top to bottom, are arranged a first ventilation assembly, a heating element 62, and a second ventilation assembly. The first ventilation assembly includes a first vent 63 penetrating the left side of the housing, inside which are a first miniature solenoid valve 64 and a first miniature fan 65. The second ventilation assembly includes a second vent 66 penetrating the left side of the housing, inside which are a second miniature solenoid valve 67 and a second miniature fan 68. The heating element 62 is a miniature heating rod. During temperature regulation, when it is necessary to raise or maintain the temperature, the power of the heating element is set appropriately. The first micro solenoid valve 64 and the second micro solenoid valve 67 are in the closed state, and the first micro fan 65 and the second micro fan 68 rotate to promote uniform temperature distribution. When it is necessary to lower the temperature, the power of the heating element is reduced, the first micro solenoid valve 64 and the second micro solenoid valve 67 are in the open state, and the first micro fan 65 and the second micro fan 68 rotate to introduce outside air for air circulation, thereby reducing the temperature inside the heating module.

[0035] like Figure 5 and Figure 6As shown, a first monitoring component 21 and a second monitoring component 22 are sequentially arranged from top to bottom on the inner side of the side heating unit 2. The first monitoring component 21 includes a first electrically controlled telescopic rod 211 symmetrically arranged and a first monitoring plate 212 disposed between the first electrically controlled telescopic rods. The second monitoring component 22 includes a second electrically controlled telescopic rod 221 symmetrically arranged and a second monitoring plate 222 disposed between the second electrically controlled telescopic rods. Both the first electrically controlled telescopic rod 211 and the second electrically controlled telescopic rod 221 are disposed in the area between the short side of the side heating unit 2 and the adjacent mounting through hole 5 to avoid being affected by heat during heating. The second monitoring plate 222 is 15cm away from the heated mattress 1. Multiple ultrasonic ranging sensors and multiple temperature sensors are alternately and evenly spaced on the second monitoring plate 222. The first monitoring plate 212 and the second monitoring plate 222 are 10cm apart. Multiple temperature sensors are equally spaced on the first monitoring plate 212. The temperature sensors are Max30205 electronic temperature sensors, and the ultrasonic ranging sensors are ultrasonic sensors manufactured by MICROSONIC (Germany), specifically model mic+35 / IU / TC. Data from the ultrasonic ranging sensors and temperature sensors are transmitted wirelessly to the data processing module. In operation, the extension length of the first and second monitoring plates is adjusted by the electrically controlled telescopic rod to detect the actual heating temperature of each heating module acting on the patient. The data processing module can determine whether the temperature distribution is uniform based on the actual heating temperature of each area. If the temperature distribution is uneven, the power of each heating module is adjusted to achieve uniform heating. In non-operating mode, the electrically controlled telescopic rod retracts, and the first and second monitoring plates return to their initial positions, which are identical. The calculation process for the extension length of the first and second monitoring plates is as follows: the distance between the second monitoring plate and the patient is calculated based on the data from the ultrasonic ranging sensor. The extension length of the second monitoring plate is calculated based on the distance of 8cm between the monitoring plate and the patient. The extension lengths of the first and second monitoring plates are the same.

[0036] The data processing module uses a laptop computer to intelligently control the rewarming process based on data from the vital signs monitoring module. The intelligent control process involves receiving instructions, activating the heated mattress and individual heating modules, and heating the patient according to preset control parameters at a rate of 0.5℃ / hour. The rewarming process is monitored in real-time based on data from the vital signs monitoring module. When the patient's core body temperature reaches the preset target temperature and physiological indicators are normal, the heated mattress and individual heating modules are controlled to maintain a constant body temperature, entering a constant temperature maintenance mode. A timer is then started, and when the timer reaches the set time (usually 2-4 hours, specified by medical staff), the rewarming process is stopped, and all data from the entire rewarming process is recorded.

[0037] The specific process of real-time monitoring is as follows: when any of the heart rate, blood oxygen saturation or blood pressure is outside the normal range, the heating power of the heated mattress and each heating module is reduced in a set step size, the rewarming rate is reduced to 0.3℃ / hour, and a reminder is issued to medical staff. When the difference between the patient's skin temperature and core temperature is greater than 2℃, the heating power of the heating module is increased in a set step size, the heating intensity of the hot air heating unit is increased, and peripheral circulation is improved.

[0038] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
