[0032] The present application provides a hypothermia treatment device 10 and a medical device 100 using the same. Figure 1 , Figure 1 It is a structural schematic diagram of embodiment 1 of the medical device provided in this application.

[0033] The medical device 100 includes an extracorporeal circulation device 20 and a cooling therapy device 10. The temperature control component 12 and the temperature measurement component 14 in the cooling therapy device 10 are attached to the pipeline or liquid processor of the extracorporeal circulation device 20 to combine temperature detection and cooling therapy to achieve a better treatment effect.

[0034] The cooling treatment device 10 can be used for cryotherapy, which can be divided into deep hypothermia therapy, cryotherapy and mild hypothermia therapy according to different treatment temperatures. Mild hypothermia therapy is a treatment method that uses physical methods to reduce the patient's body temperature to a desired level of about 30-35°C to achieve certain diseases.

[0035] Studies have found that mild hypothermia has a regulatory effect on cerebral blood flow, can reduce brain oxygen metabolism rate and improve cell energy metabolism, reduce the release of excitatory amino acids, reduce the generation of oxygen free radicals, reduce intracellular calcium overload, increase neuronal ubiquitin synthesis, reduce neuronal necrosis and apoptosis, promote the recovery of intercellular signal conduction, reduce the area of ​​cerebral infarction, reduce brain edema and reduce intracranial pressure, etc. Studies have also found that hypothermia has no effect on blood pressure, blood oxygen partial pressure, carbon dioxide partial pressure, blood pH and blood sugar, and no pathological damage was found in the heart, lungs, kidneys and small intestine of experimental animals, indicating that hypothermia does not increase damage to other tissues and organs.

[0036] Combined with reference Figures 1 to 3 The hypothermia treatment device 10 includes a plurality of temperature control components 12, a plurality of temperature measuring components 14 and a controller 16, wherein the plurality of temperature control components 12 each include a temperature control element 122 and a first accessory 124, the first accessory 124 is connected to the temperature control element 122 and is attached to the extracorporeal circulation device 20, so that the temperature control element 122 can control the temperature of the temperature control point on the extracorporeal circulation device 20; the plurality of temperature measuring components 14 each include a temperature measuring element 142 and a second accessory 144, the second accessory 144 is connected to the temperature measuring element 142 and the first accessory 144 is connected to the temperature measuring element 144. The temperature measuring component 142 is connected to the extracorporeal circulation device 20 and is used to be attached to the extracorporeal circulation device 20 so that the temperature measuring component 142 can measure the temperature of the temperature measuring points on the extracorporeal circulation device 20; the controller 16 is communicated with the temperature control component 122 and the temperature measuring component 142, and is used to adjust the working power of the temperature control component 122 based on the input target temperature and the real-time temperature obtained by the temperature measuring component 142; the display 18 is connected to the controller 16, and is used to display the working power of each temperature control component 122 and the real-time temperature obtained by each temperature measuring component 142.

[0037] Among them, the display 16 can be a touch screen display area or a non-touch screen display, which can display the data of each temperature control component 122 and each temperature measuring component 142, so that medical personnel can more directly obtain various data information during the cooling treatment process, and then medical personnel can better intervene in the cooling treatment process based on this information.

[0038] Optionally, the display 16 is a touch screen display area, and the medical staff can also set the target temperature during the cooling treatment through the display 16, and control the working status of each temperature control component 122 and each temperature measuring component 142.

[0039] Multiple groups of temperature control components 12 correspond to multiple temperature control points for multi-point temperature control, so that the temperature can be raised or lowered in stages; multiple groups of temperature measuring components 14 correspond to multiple temperature measuring points for multi-point temperature measurement to achieve accurate detection of each temperature measuring point. The controller 16 can control the working power of each temperature control component 122 in stages based on the input target temperature and the real-time temperature of the corresponding temperature point obtained by each temperature measuring component 142.

[0040] In this embodiment, the temperature control component 122 is a semiconductor temperature control component, which is specifically a refrigeration semiconductor, also known as a semiconductor refrigerator or a thermoelectric cooler (TEC), which is a device that uses the Peltier effect of semiconductor materials for cooling and heating. The refrigeration semiconductor can achieve cooling and heating functions without the need for mechanical moving parts, no noise, high-precision temperature control and fast response.

[0041] The temperature control component 122 is capable of cooling and reheating, so that the multiple groups of temperature control components 12 can perform cryogenic treatment on the blood entering the extracorporeal circulation device 20. When performing cryogenic treatment, the multiple groups of temperature control components 12 cool the blood flowing through in turn, so that the temperature of the blood returning to the human body drops to the target temperature, so as to perform cryogenic treatment on the patient. After the cooling treatment is completed, the multiple groups of temperature control components 12 reheat the blood flowing through in turn, so that the blood is reheated to normal temperature before returning to the human body.

[0042] Optionally, the temperature control components 122 may further include a heater and a refrigerator, or a portion of the temperature control components 122 may be refrigerators, and another portion of the temperature control components 122 may be heaters.

[0043] The temperature control element 122 is attached to the extracorporeal circulation device 20 through the first attachment 124, so that the temperature control element 122 can control the temperature of the temperature control point of the extracorporeal circulation device 20, which can be heating, cooling, or both. The first attachment 124 is mainly used to connect and fix to the extracorporeal circulation device 20, so that the temperature control element 122 can continuously act on the temperature control point.

[0044] The first accessory 124 can be detachably connected to the extracorporeal circulation device 20. The first accessory 124 can be fixed to the extracorporeal circulation device 20 in a variety of ways. The first accessory 124 is wrapped around the temperature control point of the extracorporeal circulation device 20, or the first accessory 124 is snapped onto the temperature control point of the extracorporeal circulation device 20, or the first accessory 124 is magnetically attracted to the temperature control point of the extracorporeal circulation device 20. These methods can all make it convenient to fix it on the extracorporeal circulation device 20, and enable the temperature control component 122 to control the temperature of the liquid in the relevant pipelines or liquid processors on the extracorporeal circulation device 20.

[0045] Alternatively, if Figure 2As shown, the first accessory 124 can be a bandage, which wraps the temperature control component 122 on the extracorporeal circulation device 20. Specifically, the first accessory 124 can be an elastic bandage or a self-adhesive bandage, which can be wrapped around the pipeline or elastically sleeved on the liquid treatment device. The bandage is low in cost and easy to install and operate, and also has a certain thermal insulation effect, and can fix the temperature control component 122 on the extracorporeal circulation device 20.

[0046] Optionally, the first accessory 124 can also be a snap-fit ​​component, and the temperature control component 122 is connected to the first accessory 124. The first accessory 124 can be snap-fitted to a pipeline or a liquid processor, so that the temperature control component 122 can act on the temperature control point.

[0047] Optionally, the first accessory 124 may also be a magnet, which may be installed on one side of the temperature control component 122 and may be magnetically attracted to a ferromagnetic pipeline or a liquid processor.

[0048] The temperature measuring element 142 may be a resistance thermometer, an infrared temperature sensor, a radiation temperature sensor, or a semiconductor temperature sensor.

[0049] The temperature measuring component 142 is attached to the extracorporeal circulation device 20 through the second accessory 144, so that the temperature measuring component 142 can perform real-time temperature detection on the temperature measuring point of the extracorporeal circulation device 20. The second accessory 144 is mainly used to connect and fix on the extracorporeal circulation device 20, so that the temperature measuring component 142 can continuously measure the temperature of the temperature measuring point.

[0050] The second accessory 144 can be detachably connected to the extracorporeal circulation device 20. The second accessory 144 can be fixed to the extracorporeal circulation device 20 in a variety of ways. The second accessory 144 is wrapped around the temperature control point of the extracorporeal circulation device 20, or the second accessory 144 is snapped onto the temperature control point of the extracorporeal circulation device 20, or the second accessory 144 is magnetically attracted to the temperature control point of the extracorporeal circulation device.

[0051] The structure of the second attachment 144 may be the same as or different from the structure of the first attachment 124, such as Figure 3 As shown, the second accessory 144 can be an elastic bandage or a self-adhesive bandage, etc., which wraps the temperature measuring component 142 on the extracorporeal circulation device 20; the second accessory 144 can also be a snap-fit ​​component, which can be snapped onto the extracorporeal circulation device 20; the second accessory 144 can also be a permanent magnet, which can be installed on one side of the temperature measuring component 142 and can be magnetically attracted to a ferromagnetic pipeline or liquid processor.

[0052] The multiple groups of temperature measuring components 14 are arranged at multiple different temperature measuring points, and the multiple groups of temperature measuring components 14 are at least configured to monitor the initial blood temperature leaving the human body, the blood temperature before at least one temperature control point, and the blood temperature before entering the human body.

[0053] After determining the temperature range of the blood during hypothermia treatment, or after the controller 16 receives the set temperature range for hypothermia treatment, based on the initial blood temperature obtained by the temperature measuring component 142, the blood temperature before the temperature control point and the blood temperature before entering the human body, each group of temperature control components 12 can be driven to perform hypothermia treatment. Specifically, one group of temperature control components 12 can be used to perform a large degree of cooling with high power, or a combination of multiple groups of temperature control components 12 can be used to gradually cool down in stages with low power, and the blood cooled to the target temperature can be returned to the patient's body to perform hypothermia treatment on the patient. After the cryogenic treatment is completed, the temperature of the blood needs to be rewarmed to the initial blood temperature. The blood temperature detected at each temperature measuring point will determine the working power of each temperature control component 122 during rewarming, so that the temperature control component 122 can accurately rewarm the blood temperature to the initial blood temperature for input into the human body; the blood temperature before entering the human body is further detected to feed back to the controller 16. When the blood temperature detected during cryogenic treatment is different from the target temperature, or when the detected temperature is different from the initial blood temperature or the sum of the initial blood temperature and the threshold range during rewarming, the controller 16 can fine-tune the working power of the temperature control component 122 at the previous temperature control point so that the blood temperature before entering the human body meets the temperature requirements.

[0054] Optionally, a temperature measuring point may be set before at least one temperature control point, for example, corresponding temperature measuring points may be set before two, three or all of the multiple temperature control points to reflect the blood temperature during the cooling treatment, so that medical staff or patients can know the treatment status more accurately.

[0055] By limiting the multiple temperature measuring points of the multiple groups of temperature measuring components 14, the controller 16 can more accurately understand the blood temperature at each stage, so that the working power of each temperature control component 12 can be adjusted accordingly, so that the temperature of the blood after temperature control meets the expectations, that is, the blood can be cooled and reheated after treatment, and the blood can return to the body at the set target temperature.

[0056] The multiple groups of temperature control components 12 are arranged at multiple different temperature control points, and the multiple groups of temperature control components 12 are at least configured to control the temperature of the blood after the initial blood temperature is monitored and the temperature of the blood before entering the human body.

[0057] The number of temperature control components 12 is at least two groups to correspond to the above-mentioned two temperature control points. The two temperature control points can be both set on the extracorporeal circulation pipeline of the extracorporeal circulation device 20. During the hypothermia treatment process, the two temperature control points are used for cooling. After the hypothermia treatment is completed, the two temperature control points are used for rewarming.

[0058] The multiple groups of temperature control components 12 are further configured to be attached to the liquid processor in the extracorporeal circulation device 20, and to control the temperature of the liquid flowing through the liquid processor. The liquid processor may be a dialysis filter or an intravenous pot, etc. The temperature control component 12 is attached to the liquid processor, and can control the temperature of liquids such as blood or dialysate flowing therethrough. By setting more temperature control points, and also controlling the temperature of dialysate or replacement fluid that is different from blood, and controlling the temperature of blood by utilizing the interaction between such liquids and blood, the temperature control efficiency can be further improved, so that the blood in hypothermia treatment can quickly reach the preset temperature, improve the efficiency of cooling treatment, and also enable the blood to be heated more efficiently during rewarming.

[0059] Optionally, the extracorporeal circulation device 20 includes a blood purification device, an extracorporeal membrane oxygenation device (not shown) and an extracorporeal circulation circuit, and the extracorporeal circulation device 20 can be any one of them.

[0060] The blood purification device is used to purify the patient's blood, wherein blood purification includes dialysis, filtration, adsorption or other forms of treatment of the blood to remove metabolic waste, excess water, toxins, certain drugs and other harmful substances in the blood, maintain electrolyte and acid-base balance, and maintain internal environment stability, wherein the blood purification device includes an extracorporeal circulation circuit. The hypothermic treatment device 10 can be attached to the blood purification device, so that blood purification and hypothermic treatment are combined.

[0061] The extracorporeal membrane oxygenation (ECMO) device is a temporary artificial cardiopulmonary support system used to replace or assist the patient's cardiopulmonary function. ECMO is used to provide life support for patients in severe cardiopulmonary failure, respiratory distress, acute respiratory distress syndrome (ARDS), severe pneumonia, neonatal respiratory failure or other critical conditions that cannot be improved by conventional mechanical ventilation. The extracorporeal membrane oxygenation device also has an extracorporeal circulation pipeline system, and the cooling therapy device 10 can be attached to the extracorporeal circulation pipeline system to cooperate in cooling therapy.

[0062] The extracorporeal circulation device 20 may also be a simple extracorporeal circulation circuit, which has the function of guiding blood, and the cooling treatment device 10 may be attached to the extracorporeal circulation circuit.

[0063] It can be seen that the cooling therapy device 10 provided in the present application can be used as an auxiliary device and attached to various devices with extracorporeal circulation pipelines, and it can be easily installed on the extracorporeal circulation device 20 and easily removed from the extracorporeal circulation device 20.

[0064] In one embodiment, see Figure 1The extracorporeal circulation device 20 includes an extracorporeal circulation circuit 21; multiple groups of temperature measuring components 14 are at least arranged on the extracorporeal circulation circuit 21, and are at least respectively configured to detect the initial blood temperature leaving the human body, the blood temperature before at least one temperature control point, and the blood temperature before entering the human body; multiple groups of temperature control components 12 are at least arranged on the extracorporeal circulation circuit 21, and are at least respectively configured to control the blood temperature after the initial blood temperature is monitored and the blood temperature before entering the human body.

[0065] In this embodiment, the extracorporeal circulation device 20 is a blood purification device, which includes an extracorporeal circulation circuit 21. The extracorporeal circulation circuit 21 includes a first circuit 210 and a blood pump, a hemodialysis filter 211 and a venous pot 212 arranged on the first circuit 210. The first circuit 210 is divided into an arterial blood circuit and a venous blood circuit, wherein the temperature measuring components 14 are three groups, one group of temperature measuring components 14 is arranged at the starting end of the arterial blood circuit to detect the initial blood temperature leaving the human body, and two groups of temperature measuring components 14 are arranged at the tail end of the venous blood circuit and are respectively located upstream and downstream of the last temperature control point to respectively detect the blood temperature before the temperature control point and the blood temperature before entering the human body.

[0066] Two of the multiple groups of temperature control components 12 are respectively arranged at the starting end of the arterial blood path and the tail end of the venous blood path. The former controls the blood temperature after the initial blood temperature is monitored, and the latter controls the blood temperature before entering the human body.

[0067] Furthermore, the fluid circuit of the extracorporeal circulation is relatively long, and the uncertainty of the influence of heat dissipation on the fluid circuit is relatively large. Two sets of temperature control components 12 can be provided and attached to the hemodialysis filter 211 and the venous pot 212 respectively, so as to utilize the large installation area of ​​the hemodialysis filter 211 and the venous pot 212 to achieve convenient and reliable installation. By adding more temperature control components 12, the quality of cooling therapy can be made more stable and reliable, and the influence of ambient temperature and heat dissipation on the fluid circuit can be compensated.

[0068] The blood purification device also includes a dialysis line 22 and a replacement line 23. Multiple groups of temperature control components 12 are also arranged on the dialysis line 22 and the replacement line 23. The temperature control component 12 can be specifically arranged on the line or device of the dialysis line 22 or the replacement line 23, so as to control the temperature of the dialysate in the dialysis line 22 and the replacement fluid in the replacement line 23, and coordinately control the temperature of the blood in the extracorporeal circulation line 21, thereby avoiding the disturbance of the blood temperature by the relatively high temperature dialysis fluid and replacement fluid, and can also make the low temperature environment of the low temperature line section in the extracorporeal circulation line 21 more stable, thereby having a better low temperature treatment effect.

[0069] In this embodiment, multiple groups of temperature control components 12 are respectively arranged on the head end and tail end of the first pipeline 210, the hemodialysis filter 211, the intravenous pot 212, the second pipeline 220 of the dialysis pipeline 22 and the third pipeline 230 of the replacement pipeline 23.

[0070] Optionally, the temperature control component 12 may also be disposed on the dialysate bag 221 or the replacement fluid bag 231 to directly cool the dialysate or the replacement fluid.

[0071] The blood flow of the extracorporeal circulation circuit in the extracorporeal circulation device is large and stable, the circuit is also long, and a very convenient installation position can be provided. In the present application scheme, multiple sets of temperature control components can be attached to the extracorporeal circulation device through corresponding first accessories, and multiple sets of temperature measuring components can be attached to the extracorporeal circulation device through corresponding second accessories, so that the cooling treatment device can achieve good cooling treatment effect with the help of the extracorporeal circulation circuit in the extracorporeal circulation device. The controller can monitor the temperature value of each temperature measuring point in real time with the help of multiple sets of temperature measuring components installed on the extracorporeal circulation device, thereby adjusting the working power of each temperature control component based on the set target temperature. Directly cooling the blood in the extracorporeal circulation circuit, and further directly displaying the working power of each temperature control component and the real-time temperature obtained by each temperature measuring component through a display, can enable medical personnel to more directly obtain various data information during the cooling treatment process, and then medical personnel can better intervene in the cooling treatment process based on this information; compared with the existing hypothermia treatment methods, the cooling method is more direct and efficient, and also greatly reduces the treatment time, and does not contact the patient, and will not cause physical discomfort to the patient. Therefore, the cooling treatment device provided by the present application can more efficiently achieve hypothermia treatment and is patient-friendly, which can reduce the patient's discomfort.
