Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to a medical thermometer for temperature control. Background Technology

[0002] Fever is one of the most common symptoms in pediatric clinics, especially at night when young children are prone to recurrent fevers. If caregivers fail to detect it in time, persistent high fever can cause irreversible damage to the central nervous system of young children, and in severe cases, even lead to febrile seizures. Therefore, timely physical cooling intervention when a young child has a fever is of great clinical significance.

[0003] When a young child has a fever, the temperature distribution across their body is not uniform and typically varies with the stage of the fever. In the early stages of fever (the rising phase), the upper body (head and trunk) is warmer, while the lower body (calves and feet) is cooler due to peripheral vasoconstriction, with the thighs being lukewarm (sub-feverish). At this stage, cooling efforts should focus on the upper body while avoiding excessive cooling of the lower body to prevent chills. During the sustained high fever phase, the entire body temperature rises significantly, requiring comprehensive heat dissipation. Ideally, cooling devices should be able to identify the real-time temperature of different parts of the body and dynamically adjust the cooling intensity according to the stage of the fever. However, current technology cannot achieve this differentiated cooling for different areas, nor can it automatically identify and adaptively adjust the cooling process based on the fever stage.

[0004] To address the above problems, this invention proposes a medical-grade thermostat. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a medical thermometer for temperature control.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A medical body temperature control device, comprising a bed, and further comprising: Multiple heat-conducting elements are arranged along the length of the bed, and adjacent heat-conducting elements are isolated from each other to block temperature conduction; An elastic spiral tube is fitted on the outside of the bed body, and jet holes for delivering cold air into the bed body are arranged on the inner side of the elastic spiral tube. Multiple temperature sensors are fixedly connected to the elastic spiral tube, and the temperature sensors are used to detect the temperature of the heat-conducting component; Multiple electrically operated telescopic rods for driving the axial deformation of the elastic helical tube; The temperature sensor and the electric telescopic rod are arranged in groups. The temperature sensor in each group controls the electric telescopic rod in the same group to extend or shorten according to the temperature value it detects, so as to dynamically change the local pitch of the elastic helical tube in the area where the temperature sensor is located.

[0007] Furthermore, one end of the elastic spiral tube is connected to a first annular plate, and the other end is connected to a second annular plate; both the first annular plate and the second annular plate are slidably fitted with the bed body.

[0008] Furthermore, a shielding column is fixedly connected to one end of the bed; the inner diameter of the elastic spiral tube is adapted to the outer diameter of the shielding column, so that the air jet hole on the elastic spiral tube that slides to the outside of the shielding column is blocked and sealed by the surface of the shielding column.

[0009] Furthermore, a heat insulation component is connected to the bottom of the bed; a sliding groove is provided at the bottom of the bed, the heat insulation component is located in the sliding groove, and each of the heat-conducting components is fixedly connected to the heat insulation component, thereby achieving physical isolation between adjacent heat-conducting components through the heat insulation component.

[0010] Furthermore, a conductive strip is installed on the inner wall of the slide; each of the temperature sensors is equipped with an electrical contact, wherein each of the temperature sensors located below the bed body is energized by contacting the conductive strip through its electrical contact, and each of the temperature sensors located not below the bed body is de-energized.

[0011] Furthermore, an operating table is fixedly connected to the end of the bed away from the shielding column; a sliding rod is fixedly connected between the operating table and the shielding column, and both the first annular plate and the second annular plate are slidably connected to the sliding rod.

[0012] Furthermore, an electric push rod is fixedly connected to both the operating table and the shielding column, and a locking block is fixedly connected to the end of the electric push rod. The inner sides of the first annular plate and the second annular plate are provided with slots for the corresponding locking blocks to be inserted and locked.

[0013] It further includes a head cooling component, which includes a rubber component and a rubber tube. The rubber component and the rubber tube are connected end to end to form a ring. A cooling water tank is provided on the operating table. One end of the rubber tube is connected to the cooling water tank through an inlet pipe, and the other end is connected to the cooling water tank through a drain pipe.

[0014] Compared with existing technologies, this invention has the following advantages: By using multiple heat-conducting components arranged and isolated along the length of the bed, it ensures that the temperature detected by each temperature sensor accurately reflects the actual body temperature of the corresponding part of the patient. Through the grouped linkage control of the temperature sensors and the electric telescopic rod, differentiated cooling of different areas along the length of the patient's body is achieved. In the heated areas, the pitch decreases, the density of the jet nozzles increases, and the cold airflow is concentrated, thus achieving enhanced cooling. In the cold areas, the pitch increases, the density of the jet nozzles decreases, and the cold airflow is dispersed, thus avoiding excessive cooling that could cause chills.

[0015] By periodically scanning from left to right with a temperature sensor, and in conjunction with the extension and retraction of the electric telescopic rod, a dynamic tracking effect is achieved where the cooling area moves as the patient's body position changes, ensuring that the cooling area always matches the patient's actual body position.

[0016] Through the structural design that adapts the shielding column to the inner diameter of the elastic spiral tube, the jet holes that slide to the outside of the shielding column are automatically sealed by the surface of the shielding column, ensuring that the cold air is only ejected in the corresponding section of the bed, avoiding ineffective waste of cold air and improving the efficiency of cold air utilization.

[0017] By setting conductive strips on the inner wall of the chute and electrical contacts on the temperature sensor, only the temperature sensor located directly below the bed is powered on and can be activated, while the temperature sensor located below the shielding column is automatically powered off, thus avoiding temperature detection in invalid areas and saving energy consumption.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-11 As shown, the technical solution adopted by the present invention is as follows: A medical body temperature control device includes an operating table 1, a bed 2, a shielding column 3, a heat-conducting component 5, an elastic spiral tube 8, a temperature sensor 11, and an electric telescopic rod 12.

[0022] The control panel 1, bed 2, and shielding column 3 are fixedly connected in sequence along the horizontal direction, and are coaxially arranged with equal diameters. For example... Figure 1 and Figure 2 As shown, the operating table 1 is located at the far left, the bed 2 in the middle, and the shielding column 3 at the far right. The bed 2 is used to accommodate the patient. Multiple perforations are provided on the bed 2.

[0023] like Figure 2 As shown, a groove 6 is provided at the bottom of the bed body 2, extending along the length of the bed body 2 and located below it. The groove 6 extends to the right into the shielding column 3. A heat insulation component 4 is fixedly connected inside the groove 6. The heat insulation component 4 is made of heat insulation material, such as aerogel or polyurethane foam, to block heat conduction. Multiple heat conducting components 5 are fixedly connected to the heat insulation component 4, and are arranged equidistantly along the length of the bed body 2. The heat conducting components 5 are made of materials with good thermal conductivity (such as copper, aluminum, etc.), and their tips extend through the bottom wall of the bed body 2 into the interior of the bed body 2 to conduct heat from the patient's body surface downwards. Adjacent heat conducting components 5 are physically and thermally isolated from each other by the heat insulation component 4, thereby preventing temperature conduction between adjacent heat conducting components 5 and ensuring that each heat conducting component 5 can independently reflect the temperature at different locations along the length of the patient's body.

[0024] like Figure 1As shown, the elastic spiral tube 8 is sleeved on the outside of the bed body 2 and the shielding column 3. The left end of the elastic spiral tube 8 is fixedly connected to the first annular plate 7, and the right end is fixedly connected to the second annular plate 9. The inner diameter of the first annular plate 7, the inner diameter of the elastic spiral tube 8, and the inner diameter of the second annular plate 9 are all adapted to the outer diameter of the shielding column 3. When the elastic spiral tube 8 is sleeved on the outside of the shielding column 3, the inner surface of the elastic spiral tube 8 can fit against the outer peripheral surface of the shielding column 3.

[0025] Two parallel sliding rods 16 are fixedly connected between the operating table 1 and the shielding column 3, extending along the length of the bed 2. Both the first annular plate 7 and the second annular plate 9 have through holes for the sliding rods 16 to pass through. The first annular plate 7 and the second annular plate 9 are slidably fitted onto the two sliding rods 16, allowing them to slide freely along the axial direction of the sliding rods 16 (i.e., the length direction of the bed 2).

[0026] like Figure 2 and Figure 4 As shown, multiple temperature sensors 11 are fixedly connected to the inner bottom of the elastic spiral tube 8. When the elastic spiral tube 8 is sleeved on the outside of the bed body 2, each temperature sensor 11 is located in the groove 6 below the bed body 2, and the detection end of each temperature sensor 11 is in contact with a corresponding heat-conducting element 5 to detect the temperature of the heat-conducting element 5.

[0027] The temperature sensor 11 can be a contact temperature sensor (such as a thermocouple, thermistor, etc.), whose sensing end can directly contact the lower end surface of the heat-conducting element 5 to improve the accuracy of temperature detection. The temperature sensor 11 can also be a non-contact infrared temperature sensor, which obtains the temperature value by detecting the infrared radiation at the lower end of the heat-conducting element 5.

[0028] like Figure 2 As shown, a conductive strip (not specifically shown in the figure) is installed on the inner wall of the slide groove 6 below the bed body 2, extending along the length of the bed body 2. Each temperature sensor 11 is equipped with an electrical contact. When the elastic spiral tube 8 is sleeved on the outside of the bed body 2, the electrical contacts on each temperature sensor 11 located directly below the bed body 2 remain in contact with the conductive strip, thus energizing these temperature sensors 11 and enabling them to detect temperatures. However, the temperature sensors 11 located below the shielding column 3 (i.e., the part of the temperature sensors 11 that have slid to the outside of the shielding column 3) are also moved out of contact with the conductive strip along with the elastic spiral tube 8, as their section has slid to the outside of the shielding column 3. Therefore, they are de-energized and do not detect temperatures.

[0029] like Figure 2As shown, the flexible spiral tube 8 is a hollow spiral tube structure, with its interior hollow to form a cold air channel. Multiple air jet holes (not specifically shown in the figure) are opened on the inner surface of the flexible spiral tube 8. These air jet holes are equidistantly distributed along the spiral line of the flexible spiral tube 8, and the orientation of each air jet hole points towards the axis of the bed 2. An air inlet pipe 10 is connected to the right end of the flexible spiral tube 8. The air inlet pipe 10 connects to the cold air channel inside the flexible spiral tube 8 and is used to connect to external cold air devices (such as air coolers, compressed air refrigeration devices, etc.) to supply cold air to the interior of the flexible spiral tube 8.

[0030] The flexible spiral tube 8 is made of a flexible material (such as spring steel, elastic alloy, etc.), which can undergo axial expansion and contraction deformation under axial force, thereby changing the pitch. The two ends of the cold air passage inside the flexible spiral tube 8 are sealed to ensure that cold air does not leak from the ends.

[0031] like Figure 3 As shown, multiple electric telescopic rods 12 are fixedly connected to the elastic spiral tube 8. The multiple electric telescopic rods 12 are distributed along the axial direction of the elastic spiral tube 8 and are fixedly connected between two adjacent spiral coils.

[0032] like Figure 4 As shown, the temperature sensor 11 and the electric telescopic rod 12 are divided into multiple groups according to their positional correspondence. Each group includes one temperature sensor 11 and two electric telescopic rods 12. The specific grouping method is as follows: Figure 4 As shown, the temperature sensor 11 located at the leftmost end and the two electric telescopic rods 12 located at the leftmost end (one electric telescopic rod 12 is located at the leftmost end above the elastic spiral tube 8, and the other electric telescopic rod 12 is located at the leftmost end below the elastic spiral tube 8) form a group. Then, the remaining temperature sensors 11 and electric telescopic rods 12 are divided into other groups in sequence from left to right.

[0033] Each temperature sensor 11 and the two electric telescopic rods 12 in the same group are electrically connected to the controller. The temperature sensor 11 transmits the detected temperature value to the controller, which controls the two electric telescopic rods 12 in the same group to extend or retract synchronously based on the temperature value. The two electric telescopic rods 12 in the same group maintain synchronous movement when extending or retracting to ensure that the axial force applied to the elastic helical tube 8 is uniform.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, both the operating platform 1 and the shielding column 3 are fixedly connected to an electric push rod 15, and each electric push rod 15 has a locking block 14 fixedly connected to its telescopic end. Specifically, in this embodiment, two electric push rods 15 are fixedly connected inside the operating platform 1, and the two electric push rods 15 are symmetrically distributed. Two electric push rods 15 are also fixedly connected inside the shielding column 3, and the two electric push rods 15 are symmetrically distributed.

[0035] Two slots 13 are provided on the inner side of the first annular plate 7 and the inner side of the second annular plate 9. The two slots 13 on the first annular plate 7 are used to form an insertion engagement with the two locking blocks 14 on the operating table 1. The two slots 13 on the second annular plate 9 are used to form an insertion engagement with the two locking blocks 14 on the shielding column 3.

[0036] When the electric push rod 15 extends, the locking block 14 extends and inserts into the corresponding slot 13, forming a locking engagement. When the electric push rod 15 retracts, the locking block 14 exits the slot 13 and retracts into the operating table 1 or the blocking column 3, releasing the locking engagement.

[0037] In one embodiment, a head cooling component is also included.

[0038] The head cooling component is used to locally cool the patient's forehead. The head cooling component includes a rubber tube 19 and a rubber element 20, both of which have a serpentine (i.e., wavy or folded) structure and are connected end-to-end to form a ring. Both the rubber tube 19 and the rubber element 20 are made of elastic rubber materials (such as silicone rubber, natural rubber, etc.). In this embodiment, the rubber tube 19 is a hollow tubular structure.

[0039] like Figure 9 As shown, a cooling water tank 23 is fixedly connected to the control panel 1. The cooling water tank 23 stores coolant (such as water or a special coolant) and has a built-in refrigeration device (such as a thermoelectric cooler, a compressor refrigeration system, etc.) for cooling the coolant. An inlet pipe 21 and a drain pipe 22 are fixedly connected to the cooling water tank 23. One end of the inlet pipe 21 is connected to the outlet of the cooling water tank 23, and the other end is connected to one end of the rubber hose 19. One end of the drain pipe 22 is connected to the return port of the cooling water tank 23, and the other end is connected to the other end of the rubber hose 19. Thus, the cooling water tank 23, the inlet pipe 21, the rubber hose 19, and the drain pipe 22 together form a closed coolant circulation loop.

[0040] The serpentine structure of the rubber tube 19 has the following two technical advantages: First, it extends the flow path of the coolant within the rubber tube 19, increasing the contact area and heat exchange time between the coolant and the wall of the rubber tube 19, thereby improving heat exchange efficiency. Second, it increases the radial expandability of the rubber tube 19, allowing the annulus formed by the rubber tube 19 and the rubber component 20 to accommodate patients with different head diameters.

[0041] In one embodiment, such as Figure 2As shown, the control panel 1 also includes a wireless thermometer 17 and a fixed control panel 18. The wireless thermometer 17 is a medical wireless temperature patch, which can be attached to the patient's armpit to detect the patient's core body temperature in real time and transmit the temperature data to the control panel 18 via wireless communication (such as Bluetooth, WiFi, etc.). The control panel 18 is a touch screen with a built-in controller, used to display body temperature data, detection data from the temperature sensor 11, and control the operation of the entire device. The control panel 18 also has multiple operation buttons or virtual buttons for starting the device, setting temperature thresholds, viewing historical data, etc.

[0042] Working principle: such as Figure 2 As shown in the figure, the state is the initial state of the equipment. At this time, the two electric push rods 15 on the shielding column 3 are in the extended state, and the two locking blocks 14 are inserted into the two locking slots 13 on the second annular plate 9, so that the second annular plate 9 is fixedly connected to the shielding column 3. The two electric push rods 15 on the operating table 1 are in the retracted state, and the first annular plate 7 and the operating table 1 are in the unlocked state.

[0043] First, multiple electric telescopic rods 12 are controlled to shorten synchronously, reducing the pitch of the elastic spiral tube 8. Since the second annular plate 9 is locked to the blocking post 3 and cannot move, the first annular plate 7 is in a sliding state. Therefore, during the shortening of the electric telescopic rods 12, the elastic spiral tube 8 will pull the first annular plate 7 to the right along the slide rod 16, thereby exposing the space above the bed 2.

[0044] Next, place the patient inside the bed 2, with the patient's head facing the operating table 1, i.e., to the left. Then, place the ring formed by the rubber tube 19 and rubber component 20 over the patient's forehead. Since the natural diameter of the ring formed by the rubber tube 19 and rubber component 20 is smaller than the diameter of a typical patient's head, it is necessary to expand the rubber tube 19 and rubber component 20 outwards before wearing it. Because both the rubber tube 19 and rubber component 20 are elastic and serpentine in shape, the diameter of the ring can be easily increased. After placing the ring on the patient's head, position the rubber tube 19 on the patient's forehead and the rubber component 20 at the back of the patient's head. Then, release the expansion force; the rubber tube 19 and rubber component 20 will recover their diameter under their own elasticity, thus tightening and fixing them to the patient's head.

[0045] Next, the wireless thermometer 17 can be attached to the patient's armpit and wirelessly paired with the control panel 18. The temperature detected by the wireless thermometer 17 can be viewed in real time through the control panel 18 for medical staff reference.

[0046] In one embodiment, a flexible thermally conductive pad is laid on the inner bottom surface of the bed 2. The flexible thermally conductive pad is made of thermally conductive fabric, and its lower surface is in close contact with the top of each of the thermally conductive elements 5, while its upper surface is used to support the patient's body. The heat from the patient's body surface is transferred to the top of each thermally conductive element 5 via the flexible thermally conductive pad to achieve comfortable and low thermal resistance temperature acquisition.

[0047] After the patient is placed, multiple electric telescopic rods 12 are simultaneously extended, restoring the elastic spiral tube 8 to its initial pitch and resetting the first annular plate 7 to correspond with the operating table 1. Then, the two electric push rods 15 on the operating table 1 are extended, causing the two locking blocks 14 to insert into the two slots 13 on the first annular plate 7, thus establishing a fixed connection between the first annular plate 7 and the operating table 1. Simultaneously, the two electric push rods 15 on the shielding column 3 are retracted, causing the two locking blocks 14 to retract into the shielding column 3, thereby releasing the second annular plate 9 from the shielding column 3.

[0048] At this point, the first annular plate 7 is locked on the operating table 1, and the second annular plate 9 can slide freely along the slide rod 16. At this time, the elastic spiral tube 8 is in the initial working state. The entire elastic spiral tube 8 is sleeved on the outside of the bed body 2 and the shielding column 3. The jet hole on the elastic spiral tube 8 located on the outside of the bed body 2 faces the inside of the bed body 2, and the jet hole on the elastic spiral tube 8 located on the outside of the shielding column 3 is sealed by the outer surface of the shielding column 3.

[0049] After the patient lies in bed 2, their body extends along the length of bed 2. The surface temperature of the patient's body at different locations along this length is conducted to the corresponding heat-conducting components 5. Specifically, heat from the patient's upper torso is conducted to the corresponding heat-conducting component 5, heat from the patient's thighs is conducted to the corresponding heat-conducting component 5, and heat from the patient's calves and feet is conducted to the corresponding heat-conducting component 5. Because adjacent heat-conducting components 5 are physically isolated by heat-insulating components 4, no heat conduction occurs between the individual heat-conducting components 5. Therefore, the temperature on each heat-conducting component 5 can independently and accurately reflect the surface temperature of the corresponding location on the patient's body.

[0050] The equipment initiates a temperature detection cycle at regular intervals (such as every 10, 15, 20, or 30 minutes, the specific interval can be set according to actual needs). In each detection cycle, multiple temperature sensors 11 are activated sequentially from left to right along the length of the bed 2. That is, the leftmost temperature sensor 11 is activated first to detect the temperature, then the second temperature sensor 11 is activated, and so on, until the rightmost temperature sensor 11 at the bottom of the bed 2 completes its detection.

[0051] In each temperature detection cycle, after each temperature sensor 11 completes temperature detection, the controller immediately sends a control command to the two electric telescopic masts 12 in the same group based on the detected temperature value. This control command is executed before the next temperature sensor 11 is activated. Therefore, in a complete detection cycle, each group of electric telescopic masts 12 completes its extension and retraction action sequentially from left to right, and the next group of temperature sensors 11 is activated only after the previous group of electric telescopic masts 12 has completed its action.

[0052] Each time the temperature sensor 11 is activated, only the temperature sensor 11 located below the bed body 2 (i.e., the temperature sensor 11 whose electrical contacts are in contact with the conductive strip) can be activated and perform temperature detection. The temperature sensor 11 located below the shielding column 3 (i.e., the temperature sensor 11 whose electrical contacts are disconnected from the conductive strip) is in a de-energized state and will not perform temperature detection.

[0053] The temperature value detected by temperature sensor 11 represents the surface temperature of the corresponding location on the patient's body. If the temperature values ​​detected by multiple temperature sensors 11 are not higher than the set value, then it will be determined that the patient is in a normal body temperature state, and the flexible spiral tube 8 will remain stationary.

[0054] If a temperature sensor 11 detects a temperature value higher than a set value, it will determine that the patient is in a feverish state. At this time, the external cooling device is activated, and cold air is delivered into the flexible spiral tube 8 through the air inlet pipe 10. The cold air flows along the inside of the flexible spiral tube 8 and is ejected from the air jets in various areas. Since the air jets are oriented towards the axis of the bed 2, and the bed 2 has multiple perforations, the ejected cold air passes through the perforations on the bed 2 and comes into contact with the patient's body inside the bed 2, achieving air-cooling.

[0055] The temperature sensor 11 in each group controls the two electric telescopic rods 12 in the same group to perform corresponding extension and retraction actions based on the temperature value it detects.

[0056] The specific control logic is as follows: First temperature range (greater than 36.5℃): When the temperature value detected by temperature sensor 11 is greater than 36.5℃ (usually indicating that the patient's body part is in a feverish state), temperature sensor 11 controls the two electric telescopic rods 12 in the same group to retract (shorten). After the electric telescopic rods 12 shorten, they will pull the elastic spiral tube 8 in the area to contract axially, making the local pitch of the spiral tube in that area smaller. The smaller pitch means that the number of spiral turns per unit length in that area increases, that is, the density of the air jets in that area increases, and the cold air jet is more concentrated, thereby enhancing the cooling of the corresponding part of the patient's body.

[0057] The second temperature range (30℃-36.5℃): When the temperature value detected by the temperature sensor 11 is between 30℃ and 36.5℃ (usually indicating that the patient's body part is in a cool state, such as the thigh area in the early stage of fever), the temperature sensor 11 will not control the two electric telescopic rods 12 in the same group to extend or shorten, that is, keep the current length of the electric telescopic rods 12 unchanged. The pitch of the elastic spiral tube 8 in this area remains in its initial state, and the corresponding patient body part is subjected to normal air cooling treatment.

[0058] The third temperature range (25℃-30℃): When the temperature value detected by the temperature sensor 11 is between 25℃ and 30℃ (usually indicating that the patient's body part is cold, such as the lower leg and foot in the early stages of fever), the temperature sensor 11 controls the two electric telescopic rods 12 in the same group to extend. After the electric telescopic rods 12 extend, they will push the elastic spiral tube 8 in the area to extend axially, making the local pitch of the spiral tube in that area larger. The larger pitch means that the number of spiral turns per unit length in that area is reduced, that is, the density of the air jets in that area is reduced, and the cold air jet becomes more dispersed and weakened, thereby avoiding excessive cooling of the corresponding part of the patient's body and preventing the patient from experiencing discomfort due to cold (such as chills).

[0059] Fourth temperature range (18℃-24℃): When the temperature value detected by temperature sensor 11 is between 18℃ and 24℃ (usually representing room temperature, i.e., the location corresponding to temperature sensor 11 is not occupied by a patient, and is an empty space within bed 2), temperature sensor 11 will not control the two electric telescopic rods 12 in the same group to extend or shorten, i.e., the current length of the electric telescopic rods 12 remains unchanged. The pitch of the elastic spiral tube 8 in this region remains in its initial state.

[0060] It should be noted that the specific values ​​of each temperature range above are only examples of this embodiment. In actual applications, they can be set and adjusted through the operation panel 18 according to different usage scenarios (such as different age groups and different physical conditions).

[0061] The following describes the working process of the equipment in detail, using a patient in the early stages of fever as an example.

[0062] The typical characteristics of the initial stage of fever (the rising phase of body temperature) are: the patient's upper body (head and trunk) has a high temperature (usually above 36.5℃), while the lower body, the thighs, are warm to cool (30℃-36.5℃), and the calves and feet are cold (25℃-30℃).

[0063] In the temperature detection cycle, multiple temperature sensors 11 are activated sequentially from left to right. Assume the patient's upper body is located in the left section of the bed 2, the thighs are located in the middle section of the bed 2, and the calves and feet are located in the right section of the bed 2.

[0064] When the first temperature sensor 11 (located in the left section) is activated and detects a temperature higher than 36.5°C, it controls the two electric telescopic rods 12 in the same group to shorten, thus reducing the pitch of the elastic spiral tube 8 in the left section. During the shortening of the electric telescopic rods 12, since the first annular plate 7 is locked on the operating table 1 and the second annular plate 9 is in a sliding state, the contraction of the elastic spiral tube 8 will pull the second annular plate 9 to the left, simultaneously causing all the temperature sensors 11, electric telescopic rods 12, and corresponding sections of the elastic spiral tube 8 in the middle and right sections to move synchronously to the left.

[0065] Then, the next temperature sensor 11 (located in the middle section) is activated and detects that the temperature is between 30°C and 36.5°C. This temperature sensor 11 does not control the movement of the electric telescopic rod 12 in the same group, and the pitch in the middle section remains in the initial state.

[0066] Next, temperature sensor 11 (located in the right section) is activated. Detecting a temperature between 25°C and 30°C, this temperature sensor 11 controls the extension of the two electric telescopic rods 12 in the same group, increasing the pitch of the elastic spiral tube 8 in the right section. During the extension of the electric telescopic rod 12, it pushes the corresponding section of the right-hand temperature sensor 11, the electric telescopic rod 12, and the elastic spiral tube 8 to move synchronously to the left.

[0067] Continuing to the right, when a temperature sensor 11 detects a temperature between 18°C ​​and 24°C (indicating that the location is outside the patient's body area and is an empty area within the bed 2), the temperature sensor 11 does not control the movement of the electric telescopic rod 12 in the same group.

[0068] Subsequently, the temperature sensor 11 located below the shielding column 3 is not performing any detection because it is in a power-off state, and its corresponding electric telescopic rod 12 also does not move.

[0069] After a complete testing cycle, the device is in the following state: the patient's upper body (heated area) is surrounded by the shortened pitch elastic spiral tube 8, and the density of the cold air nozzles is increased, achieving concentrated and enhanced cooling. The patient's thighs (warm / cool area) are surrounded by the initial pitch elastic spiral tube 8 for conventional air cooling. The patient's calves and feet (cold area) are surrounded by the increased pitch elastic spiral tube 8, and the density of the cold air nozzles is reduced, and the airflow is dispersed to avoid excessive cooling.

[0070] The typical characteristics of a prolonged period of high fever are: the patient's whole body temperature is high, with both the upper and lower body temperatures exceeding 36.5°C.

[0071] During the temperature detection cycle, as the temperature sensors 11 are activated sequentially, the temperature detected by each temperature sensor 11 located below the bed 2 is higher than 36.5°C. Therefore, the electric telescopic rods 12 in each group will shorten sequentially, reducing the pitch of the elastic spiral tubes 8 in all corresponding areas from the patient's upper body to the lower body.

[0072] The specific process is as follows: The first temperature sensor 11 detects a temperature higher than 36.5℃, controls the electric telescopic rod 12 in the same group to shorten, reducing the pitch in that area and causing all components on the right side to move to the left. The second temperature sensor 11 detects a temperature higher than 36.5℃, controls the electric telescopic rod 12 in the same group to shorten, reducing the pitch in that area. This process continues until the last temperature sensor 11 located below the bed 2 completes its detection and controls the electric telescopic rod 12 in the same group to shorten.

[0073] After a complete testing cycle, the device is in the following state: the patient's entire body (from upper to lower body) is surrounded by the elastic spiral tube 8 with shortened pitch, and the density of cold air nozzles in all areas is increased, achieving concentrated and enhanced heat dissipation for the entire patient's body.

[0074] When the temperature sensor 11, located at the junction of the bed body 2 and the shielding column 3, detects a temperature between 18°C ​​and 24°C (indicating that the location is outside the patient's body range), the electric telescopic rod 12 will no longer be shortened, maintaining its initial pitch. Subsequently, the temperature sensor 11 located below the shielding column 3 will not activate after power is cut off.

[0075] During sleep, patients inevitably move along the length of bed 2, resulting in them being in different positions within bed 2 at different times. Because the device performs a complete temperature detection cycle and pitch adjustment cycle at regular intervals, it can continuously track the patient's real-time positional changes.

[0076] For example, suppose the patient's upper body is initially located in the left section of bed 2. After a period of time, the patient moves to the right, moving their upper body to the middle section of bed 2. In the next detection cycle, temperature sensor 11 detects that the temperature in the middle section is higher than 36.5℃, while the temperature in the left section becomes 18℃-24℃ (vacancy). Therefore, the electric telescopic rod 12 in the middle section shortens, reducing the pitch, while the electric telescopic rod 12 in the left section remains in its initial state (because it does not operate in the 18℃-24℃ range). In this way, after one detection cycle, the device adjusts the cooling area from the original left section to the middle section, achieving dynamic tracking of the patient's movement.

[0077] As the electric telescopic rod 12 extends or retracts, it drives all the electric telescopic rods 12 on its right side and the elastic spiral tube 8 to move synchronously. Therefore, the pitch distribution of the entire elastic spiral tube 8 can be shifted as a whole with the movement of the patient, ensuring that the cooling area always corresponds to the fever area of ​​the patient's body.

[0078] After each temperature detection cycle, the equipment adjusts the pitch of each region of the elastic spiral tube 8 based on the detection results.

[0079] Simultaneously, when the wireless thermometer 17 detects that the patient is feverish (i.e., the axillary temperature is higher than 37.5℃), the device activates the cooling water tank 23, allowing the coolant in the cooling water tank 23 to enter the rubber tube 19 through the inlet pipe 21, and then flow back to the cooling water tank 23 through the outlet pipe 22 for circulating cooling. As the coolant continuously flows through the rubber tube 19, it exchanges heat with the patient's forehead through the tube wall, achieving localized cooling of the patient's forehead.

[0080] During the cooling process, the equipment maintains its current pitch adjustment for a certain period (e.g., 5-15 minutes) to ensure sufficient heat dissipation time. Afterward, the controller returns all the electric telescopic rods 12 to their initial length, restoring the elastic spiral tube 8 to its initial working state. Then, the next temperature detection cycle begins, re-detecting the temperature of each part of the patient's body, readjusting the pitch of each area, and entering the next cooling cycle.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
