Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular, to an operating table with a temperature control function. Background Art

[0002] In traditional surgical operations, precise regulation of the patient's body temperature is one of the key factors to ensure surgical safety and postoperative recovery. In the prior art, the temperature control function of the operating table usually adopts a single temperature sensor combined with a global heating or cooling device, and cannot achieve dynamic regional adjustment. For example, some operating tables only intervene in the patient's overall temperature through an electric blanket or a circulating water pad, and it is difficult to meet the different temperature requirements of different surgical sites. For example, during the operation, brain protection is required or local hypothermia is required in neurosurgery, while normal body temperature needs to be maintained in the trunk and limbs. Such a rough temperature control scheme may cause local overheating or overcooling, leading to complications such as burns and hypothermia syndrome. At the same time, it lacks adaptability to the patient's individual characteristics, such as age, weight, and surgical type, and there are significant clinical risks.

[0003] In addition, most of the existing temperature control systems rely on manual setting of fixed thresholds and cannot dynamically adjust according to real-time data during the operation, such as body temperature fluctuations and environmental temperature changes. When the patient's body temperature drops suddenly due to anesthesia or blood loss, the traditional system is difficult to respond in time, which may delay the intervention time and increase the risks related to hypothermia, such as coagulation dysfunction and increased postoperative infection rate.

[0004] In addition, the traditional temperature control system lacks a hierarchical warning mechanism, and extreme temperatures may cause serious medical accidents due to alarm delays.

[0005] The present invention is made based on the above situation. Summary of the Invention

[0006] The present invention overcomes the deficiencies of the prior art and provides an operating table with a temperature control function.

[0007] The present invention is achieved through the following technical solutions:

[0008] An operating table with a temperature control function includes a bed frame, the bed frame at least includes three regions: a headrest section, a backrest section, and a legrest section. Each region is provided 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 the signal of the first temperature sensor to control the corresponding temperature control structure to adjust the temperature;

[0009] The control system includes a computer terminal. The patient's basic information is entered on the computer terminal, and the control system presets a first temperature threshold corresponding to the basic information;

[0010] When the first temperature sensor senses that the temperature in the corresponding area is lower than the first temperature threshold, the control system activates the heating mechanism in that area for heating; when the first temperature sensor senses that the temperature in the corresponding area is higher than the first temperature threshold, the control system activates the cooling mechanism in that area for cooling.

[0011] For an operating table with a temperature control function as described above, a temperature fluctuation limit value, a high temperature limit value, and a low temperature limit value are preset on the computer terminal; the control system further includes a timer and an alarm. When the first temperature sensor detects that the temperature change amount is greater than the temperature fluctuation limit value within the preset time, the alarm emits an alarm signal; when the first temperature sensor detects that the temperature is greater than the high temperature limit value, the alarm emits an alarm signal; when the first temperature sensor detects that the temperature is less than the low temperature limit value, the alarm emits an alarm signal.

[0012] For an operating table with a temperature control function as described above, the operating table further includes a second temperature sensor for detecting the room temperature of the operating room. A second temperature threshold is also preset in the computer terminal. 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] For an operating table with a temperature control function as described above, the first temperature sensor includes a plurality of first thermocouples provided on the headrest section, a plurality of second thermocouples provided on the backrest section, and a plurality of third thermocouples provided on the legrest section.

[0014] For an operating table with a temperature control function as described above, 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 legrest section.

[0015] For an operating table with a temperature control function as described above, the heating mechanism includes a heating film provided below the first temperature sensor.

[0016] For an operating table with a temperature control function as described above, the cooling mechanism includes a condensing pipe provided when the heating film is lowered.

[0017] An operating table with a temperature control function as described above, wherein the headrest section is slidably connected to the backrest section, and a first adjustment structure for adjusting the distance between the two is provided between the headrest section and the backrest section. A hip rest section for the patient's buttocks to rest on is also provided between the leg rest section and the backrest section. The backrest section is hinged to the hip rest section, and a second adjustment structure for adjusting the angle between the two is provided between the backrest section and the hip rest section. The leg rest section is hinged to the hip rest section, and a third adjustment structure for adjusting the angle between the two is provided between the leg rest section and the hip rest section.

[0018] An operating table with a temperature control function as described above, wherein the leg rest section includes a left leg rest part and a right leg rest part, and the left leg rest part is hinged to the right leg rest part, so that the left leg rest part and the right leg rest part can be opened or closed relative to each other.

[0019] An operating table with a temperature control function as described above, wherein a first temperature sensor and a temperature control structure for adjusting the temperature are also provided on the hip rest section.

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

[0021] By dividing the operating table into three independent temperature control areas: the headrest section, the backrest section, and the leg rest section, and respectively configuring temperature sensors and heating / cooling dual-mode control structures, the present invention can accurately control the temperature according to the different requirements of different surgical sites, such as the need for low head temperature in neurosurgery and the need for constant trunk temperature in abdominal surgery. Compared with the traditional single global temperature control scheme, it effectively avoids the risk of local overheating or overcooling, and significantly reduces the intraoperative complication rate and postoperative infection rate.

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

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

[0030] As Figures 1 to 5 shown, an operating table with a temperature control function includes a bed frame 1. The bed frame 1 at least includes three regions: a headrest section 2, a backrest section 3, and a leg rest section 4. Each region is provided with a first temperature sensor 5 for monitoring temperature and a temperature control structure for adjusting temperature. The temperature control structure includes a heating mechanism 6 and a cooling mechanism 7. The operating table further includes a control system 8 that can receive the signal of the first temperature sensor 5 to control the corresponding temperature control structure to adjust the temperature.

[0031] The control system 8 includes a computer terminal. Patient basic information is entered on the computer terminal, and the control system 8 presets a first temperature threshold corresponding to the basic information.

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

[0033] By dividing the operating table into three independent temperature control regions: the headrest section 2, the backrest section 3, and the leg rest section 4, and respectively configuring the first temperature sensor 5 and the heating / cooling dual-mode control structure, the present invention can accurately control the temperature according to the different requirements of different surgical sites, such as the need for low head temperature in neurosurgery and the need for constant trunk temperature in abdominal surgery. Compared with the traditional single global temperature control scheme, it effectively avoids the risk of local overheating or overcooling, and significantly reduces the intraoperative complications and postoperative infection rate. The control system 8 presets the first temperature threshold based on the patient's basic information and dynamically adjusts the temperature control strategy in combination with the real-time monitoring data. When abnormal temperature fluctuations are detected in a certain region during the operation, the system can immediately activate the heating mechanism 6 or the cooling mechanism 7 of the corresponding region, avoiding the delay of manual intervention and improving the response efficiency.

[0034] Further, a temperature fluctuation limit value, a high temperature limit value, and a low temperature limit value are preset on the computer terminal; the control system 8 further includes a timer and an alarm. When the first temperature sensor 5 detects that the temperature change amount is greater than the temperature fluctuation limit value within the preset time, the alarm emits an alarm signal; when the first temperature sensor 5 detects that the temperature is greater than the high temperature limit value, the alarm emits an alarm signal; when the first temperature sensor 5 detects that the temperature is less than the low temperature limit value, the alarm emits an alarm signal. Among them, the alarm can be a flashing light and / or a buzzer, and the alarm signal can be a flashing light and a buzzer sound.

[0035] In this case, by presetting the temperature fluctuation limit, high temperature limit and low temperature limit, the system can monitor abnormal changes in the patient's body temperature in real time. In one embodiment, the temperature fluctuation limit is ±1.0℃. When the temperature in a certain area fluctuates by more than ±1.0℃ for three consecutive times within one hour, it indicates that the body temperature may be unstable due to anesthesia reaction or blood loss. The alarm is triggered immediately to remind medical staff to intervene and check; in one embodiment, the high temperature limit is 42℃ and the low temperature limit is 35℃. If the temperature exceeds 42℃ or is lower than 35℃, it is directly judged as a high-risk event, triggering an emergency alarm and automatically fusing the temperature control operation, stopping heating or accelerating cooling. Compared with the traditional single threshold alarm mechanism, the multiple threshold design significantly improves the ability to capture progressive risks and sudden risks.

[0036] The timer and the alarm work together to effectively distinguish between short-term interference and persistent anomalies. For example, only when the temperature fluctuation exceeds the limit value and lasts for a preset time, such as a detection interval of 5 seconds, and the temperature fluctuation is detected to exceed the limit value for 3 consecutive times, the system will determine it as a valid alarm to avoid false alarms caused by instantaneous noise data; and for continuous exceeding of the limit, the system automatically upgrades 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 room temperature of the operating room. 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 8 controls the air conditioning system to adjust the room temperature to within the second temperature threshold. The networking method of the control system 8 and the air conditioning system can be the air conditioning Internet of Things system in the patent publication number CN112944588A, and the patent file name is the air conditioning Internet of Things system. Of course, other networking methods can also be used.

[0038] In this case, a second temperature sensor is added to monitor the room temperature of the operating room in real time, and it is linked with the air conditioning system to achieve dual coordinated regulation of local temperature control of the operating table and environmental temperature control of the operating room. For example, when the patient's body temperature drops due to blood loss, the system not only starts the heating module of the operating table, but also simultaneously raises the room temperature to the second temperature threshold. The second temperature threshold can be 24°C, which reduces the heat exchange between the patient's body surface and the environment, and significantly improves the overall body temperature maintenance efficiency. Compared with the traditional solution that only relies on single-point temperature control of the operating table, coordinated regulation can reduce the energy consumption of the temperature control system, avoid repeated imbalances in body temperature caused by room temperature fluctuations, and quickly offset environmental interference.

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

[0040] In one embodiment, the headrest section 2, the backrest section 3, and the legrest section 4 all include a placement seat 200 provided on the bed frame 1. A placement groove 201 for placing the heating mechanism 6 and the cooling mechanism 7 is provided on the placement seat 200. The outside of the placement seat 200 is wrapped with a wrapping layer 202 having good thermal conductivity. A through hole 203 for the first temperature sensor 5 to pass through is provided on the wrapping layer 202. The wrapping layer 202 can be made of metal or carbon-based material or silicone material.

[0041] In one embodiment, the heating mechanism 6 includes a heating film provided below the first temperature sensor 5. Among them, the heating film can be a metal heating film or a carbon-based heating film or a polymer heating film.

[0042] Further, the cooling mechanism 7 includes a condensing pipe provided below the heating film. The condensing pipe is communicated with the refrigeration system of the air conditioning system. Of course, a compressor and a condenser for providing refrigerant for the condensing pipe can also be provided on the bed frame 1.

[0043] In one embodiment, the headrest section 2 is slidably connected to the backrest section 3. A first adjustment structure for adjusting the distance between the two is provided between the headrest section 2 and the backrest section 3. A hip rest section 9 for the patient to sit on with the buttocks is further provided between the legrest section 4 and the backrest section 3. The backrest section 3 is hinged to the hip rest section 9. A second adjustment structure 20 for adjusting the included angle between the two is provided between the backrest section 3 and the hip rest section 9. The legrest section 4 is hinged to the hip rest section 9. A third adjustment structure 30 for adjusting the included angle between the two is provided between the legrest section 4 and the hip rest section 9.

[0044] In one embodiment, the headrest section 2 is slidably connected to the backrest section 3 through a guiding slide bar. The first adjustment structure can be a threaded fastener provided on the backrest section 3. Of course, the first adjustment structure can also be an electric guide rail or other adjustment structures. The second adjustment structure 20 can be a first hinge block 21 hinged to the hip rest 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 rest 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 rest section 9 and a second gas spring 32 for supporting the leg rest section 4. One end of the second hinge block 31 is hinged to the hip rest 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 rest section 4. The operating table can flexibly adjust key parameters such as the height of the patient's head, the inclination angle of the torso, and the bending posture of the lower limbs. For example, in laparoscopic surgery, the angle between the backrest section 3 and the hip rest section 9 is adjusted to 15° through the second adjustment structure 20 to facilitate the exposure of the surgical field. In orthopedic surgery, the leg rest section 4 is abducted by 30° using the third adjustment structure 30 to meet the body position requirements for joint replacement. Compared with traditional fixed or single-degree-of-freedom adjustable operating tables, this design significantly improves the body position adaptation accuracy and reduces problems such as insufficient exposure of the surgical field or limited operation caused by improper body positions during the operation.

[0045] Furthermore, a first temperature sensor 5 and a temperature control structure for adjusting the temperature are also provided on the hip rest section 9.

[0046] Furthermore, the leg rest section 4 includes a left leg rest part 41 and a right leg rest part 42. The left leg rest part 41 is hinged to the right leg rest part 42, so that the left leg rest part 41 and the right leg rest part 42 can be opened or closed relative to each other. Different requirements for the lower limb postures in different surgical procedures can be met. For example, in gynecological or urological surgeries, the surgical field is fully exposed by spreading the legs. Compared with traditional integrated leg rests, the split design significantly improves the flexibility of body position adaptation during the operation, especially suitable for complex surgical procedures or patients with special body types.

[0047] In one embodiment, a pressure sensor 50 is also provided beside each first temperature sensor 5. A pressure monitoring graph is displayed on the display screen of the control system 8, and medical staff can give pressure intervention manually by observing the pressure monitoring graph to prevent the situation of excessive local pressure.

[0048] In one embodiment, the bed frame 1 further includes an electric lifting frame 100 capable of adjusting the bed height.
