Description

Technical Field

[0001] The present invention relates to the field of medical hot and cold compress equipment, and more specifically, to a vehicle-mounted semiconductor temperature-controlled hot and cold compress treatment device. Background Art

[0002] Soldiers are prone to acute closed trauma such as bone joint or soft tissue injuries in field conditions. When such injuries occur, they need to be treated promptly to avoid causing greater harm to the soldiers. When joints or soft tissues are injured, swelling will occur at the injured site, causing the injured to feel severe pain. In order to stop bleeding, relieve pain and reduce swelling, cold or hot compresses should be applied to the injured site as soon as possible. The more timely the treatment, the better the treatment effect and the shorter the treatment time.

[0003] However, it is difficult to equip hot and cold compress treatment devices under outdoor conditions. The prior art usually only uses some simple methods such as ice cubes or hot water bags to achieve hot and cold compresses. These simple hot and cold compress treatment methods not only have poor effects, but also the temperature of the hot and cold compresses is uncontrollable and the duration is short, and continuous hot and cold compress treatment cannot be achieved. Medical staff need to frequently replace the ice cubes or hot water bags, which makes the labor intensity of medical staff high and the use is inconvenient. Some equipment that can achieve hot and cold compress treatment is large in size and inconvenient to carry, and its portability is greatly reduced under outdoor conditions. Therefore, most of the injured in the field miss the best time for treatment because they cannot receive timely treatment. Summary of the invention

[0016] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a hot and cold compress component, first of all, compared with the simple hot and cold compress method of using ice cubes or hot water bags in the prior art, the hot and cold compress effect is better, the temperature of the hot and cold compress is controllable, and it can be used for a long time. Medical staff do not need to frequently replace ice cubes or hot water bags, which reduces the labor intensity of medical staff and is more convenient to use. At the same time, the equipment can be carried on a vehicle and can be easily reached at a field rescue point by an ambulance. The portability is greatly improved, which reduces the situation where most of the injured in the field under existing conditions cannot receive timely treatment and miss the best time for treatment.

[0018] By setting up an energy recovery component, when the PN junction cold and heat generating component is working, the energy released at the lower end is transferred to the semi-elliptical heat conductor on the energy recovery component through the cold and heat compress component. The shape of the semi-elliptical heat conductor fits the cold and heat compress component, which can better transfer cold or heat to the thermoelectric generator. The thermoelectric generator receives the transferred cold or heat and starts to work, and outputs electric energy. After inversion by the inverter, the electric energy is stored in the battery. The electric energy can be used for flipping the motor and other power consumption places on the equipment, so that the energy dissipated from the non-working end of the PN junction cold and heat generating component is utilized, reducing energy waste.

[0019] By setting a tightening component, when the motor flips to switch between hot and cold compresses, the rotation of the rotating shaft will drive the rotating drum to rotate, and the rotation of the rotating drum will drive the elliptical protrusion fixed thereto to rotate. During the 180-degree rotation, since the reset spring is set to be in a stretched state during the entire process, except when the two end points of the elliptical protrusion are pressed against the top rod, when other positions rotate, the reset spring will drive the telescopic rod to contract, and drive the PN junction hot and cold generating component and the hot and cold compress support part to rise to a certain height to ensure the smooth flipping of the hot and cold compress support part and will not be blocked by the semi-elliptical heat conductor. When the two end points of the elliptical protrusion are pressed against the top rod, the combination of the PN junction hot and cold generating component and the hot and cold compress support part is in a vertical position, thereby achieving the squeezing of the semi-elliptical heat conductor and ensuring the power generation effect of the energy recovery component.

[0020] By setting up a hot and cold compress support part, first, according to the part of the patient's limb that needs hot and cold compress, rotate the adjustment handle to drive the bidirectional lead screw to rotate, and the two ends of the bidirectional lead screw are symmetrically slidably connected to the ball nut seats on the outside. When the bidirectional lead screw rotates, the two ball nut seats will move closer to each other inside the adjustment groove, or move away from each other, thereby driving the left half support body and the right half support body to move closer to or away from each other, thereby realizing the adjustment of the opening size of the hot and cold compress support part to ensure that different limb parts can be placed, thereby improving the scope of application of the device.

[0046] like Figures 1 to 10 As shown, an embodiment of the present invention provides a vehicle-mounted semiconductor temperature control hot and cold compress therapy device, including a device housing 1; a lying pad 4 is provided at the upper end of the device housing 1, and a hot and cold compress assembly 5 for providing hot and cold compress energy is provided at a position close to the lying pad 4 on one side of the upper surface of the device housing 1, and a control console 2 is also provided at one end of the upper surface of the device housing 1, and a fixing bolt 3 for connecting and fixing the device housing 1 to the vehicle is fixedly installed on one side of the control console 2; the hot and cold compress assembly 5 includes a motor 51 arranged on the front side of the device housing 1, and a rotating shaft 52 is fixedly connected to the output end of the motor 51, and a PN junction hot and cold generating assembly 57 is fixedly provided at the middle position of the outer cylindrical surface of the rotating shaft 52; hot and cold compress supporting parts 56 are provided at the upper and lower ends of the PN junction hot and cold generating assembly 57.

[0047] like Figure 6 As shown, the PN junction cold and heat generating component 57 includes a shell 571 fixedly connected to the outer circumferential surface of the rotating shaft 52, and the upper and lower ends of the shell 571 are respectively provided with a cold end 573 and a hot end 572, and a plurality of groups of cold end metal sheet conductors 574 are provided at a position close to the cold end 573 in the shell 571, and a plurality of groups of hot end metal sheet conductors 575 are provided at a position close to the hot end 572 in the shell 571, and a plurality of groups of N-type semiconductors 576 and P-type semiconductors 577 are electrically connected between the cold end metal sheet conductors 574 and the hot end metal sheet conductors 575; the PN junction cold and heat generating component 57 also includes an energy recovery component 54 fixedly connected to the inner wall of the device housing 1.

[0048] The number of the cold-end metal sheet conductors 574 is greater than that of the hot-end metal sheet conductors 575, and the cold-end metal sheet conductors 574 and the hot-end metal sheet conductors 575 are cross-symmetrically arranged on both sides of the rotating shaft 52; the two adjacent N-type semiconductors 576 and P-type semiconductors 577 electrically connected to the same cold-end metal sheet conductor 574 form a group of PN junctions, and the lower ends of the N-type semiconductors 576 and P-type semiconductors 577 in the PN junctions are electrically connected to the two adjacent groups of hot-end metal sheet conductors 575, respectively, so that the entire N-type semiconductors 576 and P-type semiconductors 577, the cold-end metal sheet conductors 574, and the hot-end metal sheet conductors 575 together form a series circuit, and are electrically connected to the vehicle power supply through the two groups of hot-end metal sheet conductors 575 at both ends.

[0049] The cold end 573 and the hot end 572 are both made of insulating ceramic sheets.

[0050] When the hot and cold compress equipment is in use, first, the device is moved to the inside of the ambulance via rollers, and the hot and cold compress equipment is fixed by fixing bolts 3. After the ambulance moves and arrives at the field rescue site, the patient is moved onto the hot and cold compress equipment. If the patient has soft tissue injuries in the head and neck, the patient is placed on the lying pad 4, and the neck is placed on the hot and cold compress support 56 for treatment; if the patient has soft tissue injuries in the limbs, a suitable body position is selected to place the injured part of the limbs on the hot and cold compress support 56 for hot and cold compress treatment.

[0051] During treatment, the control console 2 controls the motor 51 to drive the rotating shaft 52 to rotate, thereby turning the PN junction hot and cold generating assembly 57 and the hot and cold compress support parts 56 installed at the upper and lower ends thereof, so as to select hot and cold compress. Figure 4 Under these conditions, the hot and cold compress support part 56 at the upper end is the cold end and can provide cold compress, and the hot and cold compress support part 56 at the lower end is the hot end and can provide hot compress; (it should be noted that the maximum flipping angle of the PN junction hot and cold compress generating component 57 and the hot and cold compress supporting parts 56 installed at its upper and lower ends is 180 degrees, and it will return to its original position when the hot and cold compress is replaced later, so the wires connected to the PN junction hot and cold compress generating component 57 will not be entangled).

[0052] When the PN junction heat and cold generating assembly 57 is working, the control console 2 controls the circuit connected to the PN junction heat and cold generating assembly 57 to be energized, and the current is sequentially Figure 8The route is that the current flows in from the hot-end metal sheet conductor 575, passes through the N-type semiconductor 576 and is introduced into the upper cold-end metal sheet conductor 574, and then flows into the P-type semiconductor 577 electrically connected to the cold-end metal sheet conductor 574, and then flows from the P-type semiconductor 577 into another set of hot-end metal sheet conductors 575, repeating the above current flow path, and the specific number of flows is determined by the number of PN junctions set. After completing the above circuit flow, the circuit flows out through the hot-end metal sheet conductor 575 at the end; in this process, according to the Peltier effect, it is specifically as follows:

[0053] The Peltier effect is a phenomenon in which when current passes through the junction of two different metals, one junction absorbs heat while the other junction releases heat. This phenomenon was first discovered by French physicist Peltier in 1834 and got its name from this. In semiconductors, N-type semiconductors and P-type semiconductors can be formed by doping different impurity elements. N-type semiconductors are mainly conductive by free electrons, while P-type semiconductors are mainly conductive by holes. When these two semiconductors are combined to form a PN junction, heat absorption or heat release occurs at the PN junction when current passes through. Specifically, when current flows from an N-type semiconductor to a P-type semiconductor, one junction absorbs heat to achieve cooling; conversely, when current flows from a P-type semiconductor to an N-type semiconductor, the junction releases heat to achieve heating.

[0054] It is known that in Figure 8 In the figure shown, the upper cold end 573 will achieve a cooling effect, while the lower hot end 572 will achieve a heating effect, and the degree of hot and cold can be controlled by controlling the current. The outer shell 571 is made of heat-conducting material. The cold amount of the cold end 573 will be transferred to the hot and cold compress support part 56 through the outer shell 571 to apply cold compress to the patient. If hot compress is to be achieved, start the motor 51 to flip the rotating shaft 52.

[0055] The present application sets up a hot and cold compress component 5. First of all, compared with the prior art which simply uses ice cubes or hot water bags for hot and cold compresses, the hot and cold compresses have better effects, the temperatures of the hot and cold compresses are controllable, and they can be used for a long time. Medical staff do not need to frequently replace ice cubes or hot water bags, which reduces the labor intensity of medical staff and is more convenient to use. At the same time, the device can be carried in a vehicle and can be easily reached at a field rescue point by using an ambulance. The portability is greatly improved, which reduces the situation where most of the injured in the field under the current conditions cannot receive timely treatment and miss the best time for treatment.

[0056] like Figure 7As shown, the energy recovery component 54 includes a fixing plate 541 fixedly mounted on the inner wall of the device housing 1, a battery 542 is provided on one side of the upper end of the fixing plate 541, an inverter 543 is also provided on the upper end of the fixing plate 541, a thermoelectric power generation sheet 545 is fixedly connected to the end of the fixing plate 541, and a semi-elliptical heat conductor 544 is fixedly connected to the upper surface of the thermoelectric power generation sheet 545.

[0057] When the PN junction cold and heat generating component 57 is working, only the upper end is the working end, and the cold or heat released by the lower end cannot be used and can only diffuse into the air, resulting in energy waste. In the present application, by setting an energy recovery component 54, when the PN junction cold and heat generating component 57 is working, the energy released by the lower end is transmitted to the semi-elliptical heat conductor 544 on the energy recovery component 54 through the cold and hot compress support portion 56. The shape of the semi-elliptical heat conductor 544 fits the cold and hot compress support portion 56, and can better transmit cold or heat to the temperature difference power generation sheet 545. The temperature difference power generation sheet 545 receives the transmitted cold or heat and starts to work, and outputs electrical energy. After inversion by the inverter 543, the electrical energy is stored in the battery 542. The electrical energy can be used to flip the motor 51 and other power consumption places on the equipment, so that the energy dissipated from the non-working end of the PN junction cold and heat generating component 57 is utilized, reducing energy waste.

[0058] The thermoelectric power generation sheet 545 is a prior art, which mainly uses temperature difference to generate electricity, which will not be elaborated here. It should be noted that when the cold end 573 is in contact with the semi-elliptical heat conductor 544, the temperature of the upper surface of the thermoelectric power generation sheet 545 is relatively low, and a temperature difference is generated with the temperature of the lower surface of the thermoelectric power generation sheet 545 (in contact with the air), thereby generating electricity. At this time, the air is equivalent to a heat source; when the hot end 572 is in contact with the semi-elliptical heat conductor 544, the temperature of the upper surface of the thermoelectric power generation sheet 545 is relatively high, and a temperature difference is generated with the temperature of the lower surface of the thermoelectric power generation sheet 545 (in contact with the air), thereby generating electricity. At this time, the air is equivalent to a cold source.

[0059] like Figure 4 and Figure 8As shown, both ends of the rotating shaft 52 are provided with a pressing component 55 that can drive the PN junction hot and cold generating component 57 and the hot and cold compress supporting part 56 to press down and press against the semi-elliptical heat conductor 544; the pressing component 55 includes a rotating cylinder 551 fixedly sleeved on the outer cylindrical surface of the rotating shaft 52, and both ends of the outer cylindrical surface of the rotating cylinder 551 are provided with annular grooves 553, and the two annular grooves 553 are slidably connected inside the sliders 554, one end of the slider 554 is fixedly connected to the telescopic rod 555, and the upper ends of the telescopic rod 555 are fixedly connected to the top wall of the equipment housing 1, the bottom of the telescopic rod 555 is fixedly connected to the reset spring 557, and the top of the reset spring 557 is fixedly connected to the top wall of the equipment housing 1; an elliptical protrusion 552 is fixedly connected to the middle position of the outer cylindrical surface of the rotating cylinder 551, and a push rod 556 is fixedly connected to the position of the top wall of the equipment housing 1 corresponding to the elliptical protrusion 552.

[0060] The clamping assembly 55 also includes a movable groove 53 opened on the front side of the device housing 1, and the two sides of the movable groove 53 are fixedly connected to sliding rods 58. The outer circular surfaces of the two sliding rods 58 are slidably connected to the sliding mounting body 59. The motor 51 is fixedly installed on the sliding mounting body 59, and the rotating shaft 52 rotates and penetrates the sliding mounting body 59.

[0061] When the energy recovery component 54 is working, the hot and cold compress support part 56 needs to press against the semi-elliptical heat conductor 544 to generate sufficient pressure on the temperature difference power generation sheet 545 to ensure the power generation effect of the temperature difference power generation sheet 545 (pressure is one of the key factors affecting the power generation effect of the temperature difference power generation sheet 545. The greater the pressure, the greater the power generation). In this application, by setting a pressing component 55, when the motor 51 is flipped to switch between hot and cold compresses, the rotation of the shaft 52 will drive the rotating drum 551 to rotate. Since the rotating drum 551 and the telescopic rod 555 are rotatably connected through the annular groove 553 and the slider 554, the telescopic rod 555 will not rotate with it, but the rotation of the rotating drum 551 will drive the elliptical protrusion 552 fixed thereto to rotate. After rotating 180 degrees, During the process, since the reset spring 557 is set to be in a stretched state during the whole process, except when the two end points of the elliptical protrusion 552 are tightly against the top rod 556, when other positions are rotated, the reset spring 557 will drive the telescopic rod 555 to contract, and drive the PN junction cold and heat generating component 57 and the cold and hot compress support part 56 to rise to a certain height to ensure the smooth flipping of the cold and hot compress support part 56 and will not be blocked by the semi-elliptical heat conductor 544. When the two end points of the elliptical protrusion 552 are tightly against the top rod 556, the combination of the PN junction cold and heat generating component 57 and the cold and hot compress support part 56 is just in a vertical position, thereby realizing the squeezing of the semi-elliptical heat conductor 544, thereby ensuring the power generation effect of the energy recovery component 54.

[0062] like Figure 3 and Fig.10As shown, the hot and cold compress support part 56 includes an adjustment groove 561 opened on the outer shell 571, and a two-way screw 563 is rotatably connected inside the adjustment groove 561, and one end of the two-way screw 563 extends to the outside of the outer shell 571 and is fixedly connected to the adjustment handle, and two groups of ball nut seats 562 are symmetrically slidably connected on both sides of the outer circular surface of the two-way screw 563, and the two groups of ball nut seats 562 slide inside the adjustment groove 561; the upper ends of the two groups of ball nut seats 562 are respectively fixedly connected to the left half support body 5610 and the right half support body 569; a gap filling component and a gas wrapping layer component are also provided between the right half support body 569 and the left half support body 5610.

[0063] The height of the ball nut seat 562 is flush with the height of the adjustment slot 561 to ensure that the bottom of the left half support body 5610 and the right half support body 569 are in contact with the outer shell 571, so as to ensure the smooth transmission of energy.

[0064] By setting up the hot and cold compress support part 56, when in use, first, according to the limb part of the patient that needs hot and cold compress, rotate the adjustment handle to drive the two-way screw 563 to rotate, and the two ends of the two-way screw 563 are symmetrically slidably connected to the ball nut seats 562. When the two-way screw 563 rotates, the two ball nut seats 562 will move closer to each other inside the adjustment groove 561, or move away from each other, thereby driving the left half support body 5610 and the right half support body 569 to move closer to or away from each other, thereby realizing the adjustment of the opening size of the hot and cold compress support part 56 to ensure that different limb parts can be placed, thereby improving the application range of the device, and the right half support body 569 and the left half support body 5610 are both made of heat-conducting metal, which can transfer heat and cold.

[0065] like Fig.10 As shown, the gap filling component includes a medium water storage box 564 fixedly connected to one side of the right half support body 569, a medium water storage chamber 566 is provided in the middle position of the left half support body 5610 and the right half support body 569, and a flow channel 565 is opened inside the right half support body 569 for interconnecting the medium water storage box 564 and the medium water storage chamber 566; the medium water storage chamber 566 is composed of a middle cavity between the left half support body 5610 and the right half support body 569 and a closed rubber diaphragm 567 fixedly connected around the left half support body 5610 and the right half support body 569.

[0066] After the cold and hot compress support part 56 adjusts the size of the opening of the left half support body 5610 and the right half support body 569, a gap will appear between the left half support body 5610 and the right half support body 569. When the limb is placed in it, some parts of the limb cannot receive cold or hot compress. To address this problem, the present application provides a gap filling component. When the left half support body 5610 and the right half support body 569 move away from each other, the medium water storage chamber 566 opens. Because the volume of the medium water storage box 564 is twice the maximum volume of the medium water storage chamber 566 (the maximum opening angle of the left half support body 5610 and the right half support body 569), and the height of the medium water storage box 564 is greater than that of the medium water storage chamber 566, under the action of gravity Next, the medium water flows from the medium water storage box 564 into the medium water storage chamber 566 through the circulation channel 565 and fills up the medium water storage chamber 566. At this time, the left half support body 5610 and the right half support body 569 will be filled up with the medium water, and water can be used as a good heat-conducting and cold-conducting medium to transfer heat and cold to the limbs, ensuring that after adjustment, there will be no problem that some limbs are unable to accept cold or hot compresses; when the left half support body 5610 and the right half support body 569 are close to each other, the medium water inside the medium water storage chamber 566 will be squeezed and returned to the medium water storage box 564 through the circulation channel 565, ensuring that the left half support body 5610 and the right half support body 569 can be closed normally.

[0067] like Fig.10 As shown, the gas enveloping layer assembly includes a blower 568 fixedly connected to the outside of the left half support body 5610 and the right half support body 569, and S-shaped heat exchange channels 5611 are provided inside the left half support body 5610 and the right half support body 569, and the blower 568 and the S-shaped heat exchange channels 5611 are interconnected; a dispersion shell 5612 is fixedly connected to the top of the left half support body 5610 and the right half support body 569, and a dispersion cavity 5613 is provided inside the dispersion shell 5612, and evenly distributed hot and cold air outlets 5614 are provided on the opposite side walls of the two dispersion shells, and the two dispersion cavities 5613 are respectively interconnected with the two S-shaped heat exchange channels 5611 through channels provided inside the left half support body 5610 and the right half support body 569.

[0068] When the cold or hot compress support part 56 is in use, since there is no obstruction at the upper end of its opening, it is impossible to achieve surrounding cold or hot compress on soft tissue. Therefore, by setting up a gas wrap layer assembly, when in use, it can be powered by the battery 542 to drive the blower 568 to blow outside air into the S-shaped heat exchange channel 5611, and after exchanging cold or heat with the left half support body 5610 and the right half support body 569, the air is turned into cold air or hot air, and is blown out from the cold and hot air outlet 5614 through the dispersion cavity 5613, thereby achieving the wrapping and blowing of cold or hot air on the upper part of the opening of the cold or hot compress support part 56, thereby achieving cold or hot compress on the soft tissue of the limbs, thereby improving the practicality of the cold and hot compress support part 56, and according to the needs of use, the cold and hot air outlet 5614 can be designed as a through hole inclined downward to make the wrapping better.

[0069] The working process of the technical solution provided by the present invention is as follows:

[0070] When the present invention is in use, first, the device is moved to the inside of the ambulance via rollers, and the hot and cold compress equipment is fixed by fixing bolts 3. After the ambulance moves and arrives at the field rescue site, the patient is moved to the hot and cold compress equipment. If the patient has soft tissue injuries in the head and neck, the patient is placed on the lying pad 4, and the neck is placed on the hot and cold compress support part 56 for treatment; if the patient has soft tissue injuries in the limbs, a suitable body position is selected to place the injured part of the limbs on the hot and cold compress support part 56 for hot and cold compress treatment.

[0071] During treatment, the control console 2 controls the motor 51 to drive the rotating shaft 52 to rotate, thereby turning the PN junction hot and cold generating assembly 57 and the hot and cold compress support parts 56 installed at the upper and lower ends thereof, so as to select hot and cold compress. Figure 4 Under these conditions, the hot and cold compress support part 56 at the upper end is a cold end that can provide cold compress, and the hot and cold compress support part 56 at the lower end is a hot end that can provide hot compress.

[0072] When the PN junction cold and heat generating component 57 is working, the energy released at the lower end is transferred to the semi-elliptical heat conductor 544 on the energy recovery component 54 through the cold and heat compress support part 56. The shape of the semi-elliptical heat conductor 544 fits the cold and heat compress support part 56 better, and can transfer cold or heat to the temperature difference power generation sheet 545. The temperature difference power generation sheet 545 receives the transferred cold or heat and starts to work, and outputs electric energy. After inversion by the inverter 543, the electric energy is stored in the battery 542. The electric energy can be used for the flipping of the power motor 51 and other power consumption places on the equipment, so that the energy dissipated from the non-working end of the PN junction cold and heat generating component 57 is utilized, thereby reducing energy waste.

[0073] By setting the pressing component 55, when the motor 51 is turned over to switch between hot and cold compress, the rotation of the rotating shaft 52 will drive the rotating drum 551 to rotate. Since the rotating drum 551 and the telescopic rod 555 are connected to each other through the annular groove 553 and the slider 554, the telescopic rod 555 will not rotate with it. However, the rotation of the rotating drum 551 will drive the elliptical protrusion 552 fixed thereto to rotate. During the 180-degree rotation process, since the reset spring 557 is set to be in a stretched state during the entire process, except when the two ends of the elliptical protrusion 552 are pressed against the top rod 556, the resetting spring 557 is in a stretched state during the entire process. When the semi-elliptical heat conductor 544 is rotated, the return spring 557 will drive the telescopic rod 555 to contract, and drive the PN junction cold and heat generating component 57 and the cold and hot compress support part 56 to rise to a certain height to ensure the smooth flipping of the cold and hot compress support part 56 and will not be blocked by the semi-elliptical heat conductor 544. When the two end points of the elliptical protrusion 552 are pressed against the top rod 556, the combination of the PN junction cold and heat generating component 57 and the cold and hot compress support part 56 is in a vertical position, thereby realizing the squeezing of the semi-elliptical heat conductor 544 and ensuring the power generation effect of the energy recovery component 54.
