Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to an operating table with temperature control function. Background Technology

[0002] In traditional surgery, precise control of the patient's body temperature is a key factor in ensuring surgical safety and postoperative recovery. Current technology typically uses a single temperature sensor combined with a global heating or cooling device for temperature control in operating tables, failing to achieve dynamic adjustment by specific areas. For example, some operating tables only use electric blankets or circulating water pads to intervene in the patient's overall temperature, which is insufficient to address the varying temperature requirements of different surgical sites. For instance, intraoperative brain protection or neurosurgery may require localized hypothermia, while the trunk and limbs need to maintain normal body temperature. This crude temperature control approach can lead to localized overheating or overcooling, causing complications such as burns and hypothermia syndrome. Furthermore, it lacks adaptability to individual patient characteristics, such as age, weight, and type of surgery, posing significant clinical risks.

[0003] Furthermore, existing temperature control systems mostly rely on manually set fixed thresholds and cannot dynamically adjust based on real-time intraoperative data, such as body temperature fluctuations and changes in ambient temperature. When a patient's body temperature drops suddenly due to anesthesia or blood loss, traditional systems may struggle to respond promptly, potentially delaying intervention and exacerbating hypothermia-related risks, such as coagulation disorders and postoperative infection rates.

[0004] In addition, traditional temperature control systems lack a tiered early warning mechanism, and extreme temperatures may lead to serious medical accidents due to delayed alarms.

[0005] This invention is based on the above circumstances. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides an operating table with temperature control function.

[0007] This invention is achieved through the following technical solution:

[0008] An operating table with temperature control function includes a bed frame, which includes at least three areas: a headrest section, a backrest section, and a legrest section. Each area is equipped with a first temperature sensor for monitoring temperature and a temperature control structure for adjusting temperature. The temperature control structure includes a heating mechanism and a cooling mechanism. The operating table also includes a control system that can receive signals from the first temperature sensor and control the corresponding temperature control structure to adjust the temperature.

[0009] The control system includes a computer terminal on which basic patient information is entered. The control system is preset with a first temperature threshold corresponding to the basic information.

[0010] When the first temperature sensor detects that the temperature of the corresponding area is lower than the first temperature threshold, the control system activates the heating mechanism of that area to heat it; when the first temperature sensor detects that the temperature of the corresponding area is higher than the first temperature threshold, the control system activates the cooling mechanism of that area to cool it down.

[0011] As described above, an operating table with temperature control function has preset temperature fluctuation limits, high temperature limits, and low temperature limits on a computer terminal. The control system also includes a timer and an alarm. When the first temperature sensor detects a temperature change greater than the temperature fluctuation limit within a preset time, the alarm issues an alarm signal; when the first temperature sensor detects a temperature greater than the high temperature limit, the alarm issues an alarm signal; when the first temperature sensor detects a temperature less than the low temperature limit, the alarm issues an alarm signal.

[0012] As described above, the operating table with temperature control function further includes a second temperature sensor for detecting the room temperature. The computer terminal is also preset with a second temperature threshold. The computer terminal is connected to the indoor air conditioning system. When the second temperature sensor detects that the room temperature is not within the second temperature threshold, the control system controls the air conditioning system to adjust the room temperature to within the second temperature threshold.

[0013] As described above, in an operating table with temperature control function, the first temperature sensor includes a plurality of first thermocouples disposed on the headrest section, a plurality of second thermocouples disposed on the backrest section, and a plurality of third thermocouples disposed on the legrest section.

[0014] As described above, in an operating table with temperature control function, the first thermocouple is a flexible thermocouple, and the first thermocouples are distributed in a matrix on the headrest section; the second thermocouple is a flexible thermocouple, and the second thermocouples are distributed in a matrix on the backrest section; the third thermocouple is a flexible thermocouple, and the third thermocouples are distributed in a matrix on the leg rest section.

[0015] As described above, in an operating table with temperature control function, the heating mechanism includes a heating film disposed below a first temperature sensor.

[0016] As described above, in an operating table with temperature control function, the cooling mechanism includes a condenser tube disposed below the heating film.

[0017] As described above, in an operating table with temperature control function, the headrest section is slidably connected to the backrest section, and a first adjustment structure for adjusting the distance between the headrest section and the backrest section is provided. A buttock pillow section for the patient to sit on is also provided between the leg pillow section and the backrest section. The backrest section is hinged to the buttock pillow section, and a second adjustment structure for adjusting the angle between the backrest section and the buttock pillow section is provided. The leg pillow section is hinged to the buttock pillow section, and a third adjustment structure for adjusting the angle between the leg pillow section and the buttock pillow section is provided.

[0018] As described above, in an operating table with temperature control function, the leg pillow section includes a left leg pillow and a right leg pillow, with the left leg pillow hinged to the right leg pillow, so that the left leg pillow and the right leg pillow can open or close to each other.

[0019] As described above, an operating table with temperature control function is provided on the buttock-pillow section, which also includes a first temperature sensor and a temperature control structure for adjusting the temperature.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention divides the operating table into three independent temperature-controlled zones: a head-support zone, a back-support zone, and a leg-support zone. Each zone is equipped with a temperature sensor and a dual-mode heating / cooling control structure. This allows for precise temperature control based on the specific needs of different surgical sites, such as neurosurgery requiring a low head temperature and abdominal surgery requiring a constant trunk temperature. Compared to traditional single global temperature control solutions, this effectively avoids the risks of localized overheating or overcooling, significantly reducing intraoperative complications and postoperative infection rates.

[0022] The control system presets a first temperature threshold based on the patient's basic information and dynamically adjusts the temperature control strategy in conjunction with real-time monitoring data. When abnormal temperature fluctuations are detected in a certain area during the operation, the system can immediately activate the heating or cooling mechanism of the corresponding area, avoiding delays caused by manual intervention and improving response efficiency.

[0029] The present invention will now be further described with reference to the accompanying drawings:

[0030] like Figures 1 to 5 The operating table shown includes a bed frame 1, which includes at least three areas: a headrest section 2, a backrest section 3, and a legrest section 4. Each area is equipped with a first temperature sensor 5 for monitoring the temperature and a temperature control structure for adjusting the temperature. The temperature control structure includes a heating mechanism 6 and a cooling mechanism 7. The operating table also includes a control system 8 that can receive the signal from the first temperature sensor 5 and control the corresponding temperature control structure to adjust the temperature.

[0031] The control system 8 includes a computer terminal on which basic patient information is entered. The control system 8 is preset with a first temperature threshold corresponding to the basic information.

[0032] When the first temperature sensor 5 senses that the temperature of the corresponding area is lower than the first temperature threshold, the control system 8 starts the heating mechanism 6 of that area to heat it; when the first temperature sensor 5 senses that the temperature of the corresponding area is higher than the first temperature threshold, the control system 8 starts the cooling mechanism 7 of that area to cool it down.

[0033] This invention divides the operating table into three independent temperature-controlled zones: a head-pillow section 2, a back-pillow section 3, and a leg-pillow section 4. Each zone is equipped with a first temperature sensor 5 and a dual-mode heating / cooling control structure. This allows for precise temperature control based on the differentiated needs of different surgical sites, such as neurosurgery requiring a low head temperature and abdominal surgery requiring a constant trunk temperature. Compared to traditional single global temperature control solutions, this effectively avoids the risks of local overheating or overcooling, significantly reducing intraoperative complications and postoperative infection rates. The control system 8 presets a first temperature threshold based on the patient's basic information and dynamically adjusts the temperature control strategy in conjunction with real-time monitoring data. When abnormal temperature fluctuations are detected in a certain area during surgery, the system can immediately activate the corresponding heating mechanism 6 or cooling mechanism 7, avoiding delays caused by manual intervention and improving response efficiency.

[0034] Furthermore, the computer terminal is preset with temperature fluctuation limits, high temperature limits, and low temperature limits. The control system 8 also includes a timer and an alarm. When the first temperature sensor 5 detects a temperature change greater than the temperature fluctuation limit within a preset time, the alarm emits an alarm signal; when the first temperature sensor 5 detects a temperature greater than the high temperature limit, the alarm emits an alarm signal; when the first temperature sensor 5 detects a temperature less than the low temperature limit, the alarm emits an alarm signal. The alarm may include a flashing light and / or a buzzer, and the alarm signal may consist of flashing light and a buzzer.

[0035] This system, by pre-setting temperature fluctuation limits, high temperature limits, and low temperature limits, can monitor abnormal changes in a patient's body temperature in real time. In one embodiment, the temperature fluctuation limit is ±1.0℃. If the temperature in a certain area fluctuates by more than ±1.0℃ three times consecutively within one hour, it indicates that the patient's body temperature may be unstable due to anesthesia or blood loss, and the alarm is immediately triggered, alerting medical staff to intervene and verify. In another embodiment, the high temperature limit is 42℃ and the low temperature limit is 35℃. If the temperature exceeds 42℃ or falls below 35℃, it is directly identified as a high-risk event, triggering an emergency alarm and automatically shutting off the temperature control operation to stop heating or accelerate cooling. Compared with traditional single-threshold alarm mechanisms, the multi-threshold design significantly improves the ability to detect both gradual and sudden risks.

[0036] The coordinated operation of the timer and alarm can effectively distinguish between transient disturbances and persistent anomalies. For example, the system only determines a valid alarm when the temperature fluctuation exceeds the limit and continues for a preset time, such as a detection interval of 5 seconds, and the temperature fluctuation exceeds the limit three times consecutively, thus avoiding false alarms caused by instantaneous noise data. For continuous exceedances, the system automatically escalates the alarm level to ensure that medical staff can respond quickly to real risks.

[0037] Furthermore, the operating table also includes a second temperature sensor for detecting the operating room temperature. The computer terminal is also pre-set with a second temperature threshold. The computer terminal is connected to the indoor air conditioning system. When the second temperature sensor detects that the room temperature is not within the second temperature threshold, the control system 8 controls the air conditioning system to adjust the room temperature to within the second temperature threshold. The network connection between the control system 8 and the air conditioning system can be the "Air Conditioning Internet of Things System" as described in patent document CN112944588A, or other network connection methods.

[0038] This solution incorporates a second temperature sensor to monitor the operating room temperature in real time and integrates it with the air conditioning system, achieving dual coordinated regulation of local temperature control on the operating table and overall operating room temperature. For example, when a patient's body temperature drops due to blood loss, the system not only activates the operating table heating module but also simultaneously raises the room temperature to a second temperature threshold, which can be 24°C. This reduces heat exchange between the patient's skin and the environment, significantly improving overall body temperature maintenance efficiency. Compared to traditional solutions that rely solely on single-point temperature control on the operating table, this coordinated regulation reduces energy consumption of the temperature control system, avoids repeated temperature imbalances caused by room temperature fluctuations, and quickly counteracts environmental disturbances.

[0039] In one embodiment, the first temperature sensor 5 includes a plurality of first thermocouples 51 disposed on the headrest section 2, a plurality of second thermocouples 52 disposed on the backrest section 3, and a plurality of third thermocouples 53 disposed on the legrest section 4. The first thermocouples 51 are commercially available flexible thermocouples, and the first thermocouples 51 are distributed in a matrix on the headrest section 2; the second thermocouples 52 are commercially available flexible thermocouples, and the second thermocouples 52 are distributed in a matrix on the backrest section; the third thermocouples 53 are commercially available flexible thermocouples, and the third thermocouples 53 are distributed in a matrix on the legrest section 4.

[0040] In one embodiment, the headrest section 2, backrest section 3, and legrest section 4 each include a placement seat 200 mounted on the bed frame 1. The placement seat 200 has a placement groove 201 for placing the heating mechanism 6 and the cooling mechanism 7. The outer side of the placement seat 200 is covered with a thermally conductive wrapping layer 202, and the wrapping layer 202 has a through hole 203 for the first temperature sensor 5 to pass through. The wrapping layer 202 can be made of metal, carbon-based material, or silicone material.

[0041] In one embodiment, the heating mechanism 6 includes a heating film disposed below the first temperature sensor 5. The heating film may be a metal heating film, a carbon-based heating film, or a polymer heating film.

[0042] Furthermore, the cooling mechanism 7 includes a condenser tube disposed below the heating film. The condenser tube is connected to the refrigeration system of the air conditioning system; alternatively, a compressor and condenser supplying refrigerant to the condenser tube can be mounted on the bed frame 1.

[0043] In one embodiment, the headrest segment 2 is slidably connected to the backrest segment 3, and a first adjustment structure for adjusting the distance between the headrest segment 2 and the backrest segment 3 is provided. The leg pillow segment 4 is also provided with a buttock pillow segment 9 for the patient to sit on. The backrest segment 3 is hinged to the buttock pillow segment 9, and a second adjustment structure 20 for adjusting the angle between the backrest segment 3 and the buttock pillow segment 9 is provided. The leg pillow segment 4 is hinged to the buttock pillow segment 9, and a third adjustment structure 30 for adjusting the angle between the leg pillow segment 4 and the buttock pillow segment 9 is provided.

[0044] In one embodiment, the headrest section 2 is slidably connected to the backrest section 3 via a guide slide. The first adjustment structure can be a threaded fastener provided on the backrest section 3, or it can be an electric guide rail or other adjustment structure. The second adjustment structure 20 can be a first hinge block 21 hinged to the hip pillow section 9 and a first gas spring 22 for supporting the backrest section 3. One end of the first hinge block 21 is hinged to the hip pillow section 9, and the other end is hinged to the fixed end of the first gas spring 22. The telescopic end of the first gas spring 22 is hinged to the backrest section 3. The third adjustment structure 30 can be a second hinge block 31 hinged to the hip pillow section 9 and a second gas spring 32 for supporting the leg pillow section 4. One end of the second hinge block 31 is hinged to the hip pillow section 9, and the other end is hinged to the fixed end of the second gas spring 32. The telescopic end of the second gas spring 32 is hinged to the leg pillow section 4. The operating table can flexibly adjust key parameters such as the patient's head height, trunk tilt angle, and lower limb flexion posture. For example, in laparoscopic surgery, the second adjustment structure 20 adjusts the angle between the back-occipital segment 3 and the buttock-occipital segment 9 to 15°, facilitating exposure of the surgical field. In orthopedic surgery, the third adjustment structure 30 abducts the leg-occipital segment 4 by 30° to meet the positioning requirements for joint replacement. Compared to traditional fixed or single-degree-of-freedom adjustable operating tables, this design significantly improves the accuracy of positioning and reduces problems such as insufficient exposure of the surgical field or limited operation due to improper positioning during surgery.

[0045] Furthermore, the hip pillow section 9 is also equipped with a first temperature sensor 5 and a temperature control structure for adjusting the temperature.

[0046] Furthermore, the leg pillow segment 4 includes a left leg pillow portion 41 and a right leg pillow portion 42, wherein the left leg pillow portion 41 is hinged to the right leg pillow portion 42, thereby allowing the left leg pillow portion 41 and the right leg pillow portion 42 to open or close together. This can meet the differentiated requirements of lower limb posture for different surgical procedures. For example, in gynecological or urological surgeries, opening the legs fully exposes the surgical field. Compared to traditional one-piece leg pillows, the split design significantly improves the flexibility of intraoperative positioning, especially suitable for complex surgical procedures or patients with special body types.

[0047] In one embodiment, a pressure sensor 50 is also provided next to each first temperature sensor 5. The pressure monitoring graph is displayed on the screen of the control system 8. Medical staff can prevent excessive local pressure by observing the pressure monitoring graph and manually applying pressure.

[0048] In one embodiment, the bed frame 1 also includes an electrically operated lifting frame 100 that can adjust the bed height.
