Description

Technical Field

[0001] The utility model relates to the technical field of cryotherapy, and particularly provides a cryotherapy device and its control system. Background Art

[0002] In the existing mild hypothermia treatment methods, both surface hypothermia and cavity hypothermia have their own limitations. Although surface hypothermia is easy to operate and can be achieved by using devices such as ice blankets or ice caps, the effect of this method is not ideal. Due to the slow temperature conduction speed and the difficulty in precisely controlling the cooling amplitude, patients often experience adverse reactions such as shivering. More seriously, surface hypothermia may also stimulate the myocardium, leading to arrhythmia in patients and even the risk of frostbite.

[0003] In contrast, although cavity hypothermia can theoretically reduce the patient's body temperature more effectively, the actual operation is extremely complex. This method requires drawing the patient's own blood out of the body for cooling treatment and then retransfusing it back into the body. This process not only requires high-precision cryotherapy equipment but also requires close coordination between various components. Once a problem occurs in a certain link, it may cause serious harm to the patient.

[0004] In addition, during the treatment of cavity hypothermia, various real-time adjustments are also required to ensure the stability of the patient's body temperature. However, it is often difficult to achieve such fine adjustments by manual operation, and the existing cryotherapy equipment is inconvenient to use and difficult to intelligently handle various situations.

[0005] Correspondingly, a new technical solution is needed in this field to solve the above problems. Content of the Utility Model

[0027] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0028] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," and "right," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] First refer to Figures 2 to 3 The cryogenic therapy device of this invention includes a heat exchange system 14 and an extracorporeal circulation pipeline 15 that exchanges heat with the heat exchange system 14. The extracorporeal circulation pipeline 15 includes an inlet 151 and an outlet 152. The inlet 151 is used to input blood, and the outlet 152 is used to deliver blood. The extracorporeal circulation pipeline 15 is equipped with a second pump 16, which is used to drive the flow of blood in the extracorporeal circulation pipeline 15. The heat exchange system 14 can cool the blood in the extracorporeal circulation pipeline 15. It also includes a first monitoring component for monitoring human physiological information and a second monitoring component for monitoring information of the extracorporeal circulation pipeline. The first monitoring component includes multiple components and can detect human physiological parameters (temperature, electrocardiogram, blood pressure, or blood oxygen). The second monitoring component can detect pipeline information of the extracorporeal circulation pipeline 15, including but not limited to pipeline pressure, pipeline temperature, liquid level in the pipeline, air bubbles in the pipeline, and pipeline flow rate.

[0031] The first monitoring component includes a human body temperature detector, which is used to detect the core temperature and target temperature of the human body. Two types of temperature detectors can be selected to detect the core temperature and the target temperature of the human body respectively. The core temperature test point is preferably rectal temperature, but is not limited to the esophagus, bladder, etc. The selection of the target temperature detection point is adjusted according to the location of the stroke. For stroke patients, the temperature difference between the left and right ears is preferred, not limited to the tympanic membrane. If there are other trauma points, the temperature measurement point can be automatically changed according to the actual situation.

[0032] The first monitoring component also includes an electrocardiogram detector for detecting human electrocardiogram, a blood pressure detector for detecting human blood pressure, and a blood oxygen detector for detecting human blood oxygen.

[0033] Continue reading Figure 2 The blood flow direction in the extracorporeal circulation tubing 15 is from inlet 151 to outlet 152. Before the second pump 16, the flow is between inlet 151 and the second pump 16; after the second pump, the flow is between the second pump 16 and the outlet 152. The second monitoring component includes a first temperature sensor 17 disposed before the second pump 16 for detecting the tubing temperature before the second pump 16. More preferably, the first temperature sensor 17 is disposed near inlet 151 to monitor the inlet tubing temperature.

[0034] The second monitoring component also includes a second temperature sensor 18 disposed after the second pump 16 for detecting the pipe temperature after the second pump 16. More preferably, the second temperature sensor 18 is disposed near the outlet 152 to monitor the outlet pipe temperature.

[0035] The second monitoring component also includes a first pressure sensor 19 disposed before the second pump 16 for detecting blood pressure before the second pump 16, i.e., pre-pump arterial blood pressure.

[0036] The second monitoring component also includes a second pressure sensor 20 located after the second pump 16 for detecting the blood pressure of the blood flowing back into the human body, i.e., the blood return arterial pressure.

[0037] The second monitoring component also includes a flow meter 34 disposed on the extracorporeal circulation line 15. The flow meter 34 is used to detect the flow rate and air bubbles in the line. Preferably, the flow meter 34 is a flow meter with an air bubble detection function.

[0038] Continue reading Figure 2 An air bubble removal cavity is provided on the extracorporeal circulation tubing 15. In the direction of liquid flow, the cross-sectional area of ​​the air bubble removal cavity is larger than the cross-sectional area of ​​the extracorporeal circulation tubing, so that air bubbles are collected above the air bubble removal cavity. Specifically, a first air bubble removal cavity 21 is provided on the tubing before the second pump 16, and a second air bubble removal cavity 22 is provided on the tubing after the second pump 16. Of course, this is not limiting. This utility model does not impose any restrictions on the specific number, specific location, or specific arrangement of the air bubble removal cavities. The air bubble removal cavity can be arranged vertically (all air bubble removal cavities in the attached drawings are arranged vertically, that is, the blood inlet of the air bubble removal cavity is located at the top, and the bleeding outlet of the air bubble removal cavity is located at the bottom), or it can be arranged horizontally (for example, the blood inlet is provided on the upper left side of the air bubble removal cavity, and the bleeding outlet is provided on the lower right side of the air bubble removal cavity). As long as it can collect air bubbles and prevent air bubbles from entering the human body, those skilled in the art can set it according to the actual situation.

[0039] The bubble removal chamber is designed to collect and remove air bubbles during extracorporeal circulation, thus preventing them from entering the body and causing potential harm. Because air bubbles are less dense than the liquid itself, they tend to rise to the surface. The bubble removal chamber provides a larger space for bubbles to rise and accumulate, effectively separating them from the circulating blood.

[0040] It should be noted that this utility model does not impose any restrictions on the specific type of the second pump. It can be a peristaltic pump, a magnetic levitation blood pump, or other types of pump devices, as long as it can achieve the driving function. Those skilled in the art can set it according to the actual situation.

[0041] In this preferred embodiment, a valve device is provided on the extracorporeal circulation pipeline 15 downstream of the bubble removal cavity; such as Figure 2 As shown, a first pinch valve 23 is provided after the first bubble discharge chamber 21, and a second pinch valve 24 is provided after the second bubble discharge chamber 22. Of course, this is not limiting; the valve device can be a pinch valve or other valve device capable of controlling flow rate and on / off switching. By adjusting the flow rate or opening and closing the valve device, the liquid level in the bubble discharge chamber can be controlled. An appropriate liquid level and an appropriate flow rate help the bubbles rise better to the top of the chamber and be collected.

[0042] In other embodiments, a first bubble removal chamber 21 is provided only upstream of the second pump 16, and a valve device is provided between the first bubble removal chamber 21 and the second pump 16. The number of both the bubble removal chamber and the valve device is one.

[0043] The second monitoring component also includes a level detector, configured to detect the liquid level in the cavity where air bubbles have been expelled. The level detector is preferably an external, non-contact type, such as a capacitive level detector or a photoelectric level detector. However, this is not a limitation; those skilled in the art can choose the type of level detector according to the specific circumstances.

[0044] In other embodiments, the first monitoring component includes any one or any combination of human body temperature detector, electrocardiogram detector, blood pressure detector and blood oxygen detector.

[0045] In other embodiments, the first monitoring component includes two sets of human body temperature detectors, one set for detecting the core temperature of the human body and the other set for detecting the target temperature of the human body. In addition, it also includes any one or any combination of electrocardiogram detectors, blood pressure detectors and blood oxygen detectors.

[0046] In other embodiments, the second monitoring component includes any one or more combinations of a first temperature sensor 17, a second temperature sensor 18, a first pressure sensor 19, a second pressure sensor 20, a flow meter 34, and a level detector.

[0047] Continue reading Figure 2 ,like Figure 2 In this preferred embodiment, the heat exchange system 14 includes a heat exchange circulation pipeline 141, and a chiller 143, a first pump 142, and a heat exchanger 144 disposed on the heat exchange circulation pipeline 141. The chiller 143 is capable of refrigeration, and the refrigerant in the heat exchange circulation pipeline 141 exchanges heat with the external circulation pipeline 15 in the heat exchanger 144 to cool the external circulation pipeline 15.

[0048] It should be noted that this utility model does not impose any restrictions on the specific structure of the heat exchange system 14. It can also be a refrigerant circulation loop and a refrigerant circulation loop equipped with a compressor, condenser, expansion valve and evaporator. The external circulation pipeline 15 exchanges heat with the evaporator to achieve cooling.

[0049] Further, see Figure 3 The cryotherapy device also includes an injection unit 25, which includes a container (not shown in the figure) and an injection pump connected to the container. The injection pump is connected to the extracorporeal circulation line 15 after the second pump 16. The container can contain heparin, saline or adrenaline, or other drugs used for adjuvant therapy. The drugs in the container enter the extracorporeal circulation line 15 through the injection pump and then enter the human body with the blood.

[0050] In other embodiments, the injection pump is connected to the extracorporeal circulation line 15 between the second pump 16 and the heat exchanger 144.

[0051] Secondly, this utility model also claims protection for a control system for a cryotherapy device, see reference. Figure 1 ,like Figure 1 As shown, the control system includes: a monitoring unit 12, which can communicate with a first monitoring component that monitors human physiological information and a second monitoring component that monitors the extracorporeal circulation tubing information of the cryotherapy device; a drive control unit 13, which can communicate with the drive device of the cryotherapy device; and a central processing unit 11, which can communicate with the monitoring unit 12 and the drive control unit 13 to realize information interaction.

[0052] In this preferred embodiment, the monitoring unit 12 receives information on the human body core temperature, human body target temperature, and human vital signs parameters (ECG, blood pressure, and blood oxygen) monitored by the first monitoring component, and receives information on pipeline bubble information, pipeline pressure information, pipeline temperature information, and liquid level detection information monitored by the second monitoring component. Then, it transmits the real-time information to the central processing unit 11. The central processing unit 11 can analyze the information and generate instructions to transmit to the drive control unit 13. The drive control unit 13 transmits instructions to the drive device, which includes a chiller 143, a first pump 142, a second pump 16, a first clamp valve 23, a second clamp valve 24, and an injection pump. The drive control unit 13 can recognize different instructions and issue different instructions to the corresponding drive devices to adjust the operation of the drive devices and adapt to various different situations during the treatment process.

[0053] Furthermore, in this preferred embodiment, the cryotherapy device also includes an ambient temperature sensor for detecting the ambient temperature and transmitting it to the monitoring unit 12.

[0054] In this preferred embodiment, the drive control unit 13 can both issue commands to each drive device and receive information feedback from each drive device, and monitor the operation of each drive device in real time.

[0055] The central processing unit 11 is provided with a first interface (not shown in the figure) and a second interface (not shown in the figure). The monitoring unit 12 is connected to the first interface via a first data transmission line (not shown in the figure), and the drive control unit 13 is connected to the second interface via a second data transmission line (not shown in the figure).

[0056] Based on the above structural configuration, the central processing unit 11 only needs to be equipped with two data transmission interfaces. This avoids the complexity and cost problems caused by too many data interfaces in the central processing unit 11, reduces unnecessary interfaces and connections, and lowers the complexity and maintenance costs of the system. By equipping only two data transmission interfaces, the central processing unit 11 can focus more on data transmission with the monitoring unit 12 and the drive control unit 13, which can ensure the efficiency and reliability of data transmission. In other words, the monitoring unit 12 and the drive control unit 13 share the wiring burden of the central processing unit 11 and share some of the work of the central processing unit 11, reducing the workload and wiring burden of the central processing unit 11.

[0057] Continue reading Figure 1 The control system also includes a display unit 10, which is communicatively connected to the central processing unit 11. The display unit 10 can display various information about the cryotherapy device and realize human-machine interaction functions. (See reference...) Figure 3The display unit 10 includes a display 101, an alarm indicator light 102 and mechanical buttons 103 on the display 101 for easy manual operation. The display 101 can be touch-sensitive or non-touch-sensitive.

[0058] It should be noted that this utility model does not impose any restrictions on the specific structure of the display unit 10. It may only include a control panel or only include a touch screen, as long as it can realize human-computer interaction. Those skilled in the art can set it according to the actual situation.

[0059] The display unit 10 can transmit information or instructions to the central processing unit 11. The central processing unit 11 can receive the information or instructions transmitted by the display unit 10 and perform corresponding operations. It can also transmit the information monitored by the monitoring unit 12 to the display unit 10 for display, and can also transmit the feedback information and operating status of each drive device to the display unit 10 for display.

[0060] The central processing unit 11 is provided with a third interface (not shown in the figure), and the display unit 10 is connected to the third interface through the third data transmission line to realize information interaction with the central processing unit 11.

[0061] The central processing unit 11 stores different treatment modes. Each treatment mode adjusts the components differently during the treatment process. Different treatment modes can be selected through human-computer interaction via the display unit 10. The central processing unit 11 can automatically adjust the parameters of each component according to different treatment modes and generate instructions to be sent to the drive control unit 13.

[0062] Furthermore, the control system also includes an emergency response unit (not shown in the figure), which is communicatively connected to the drive control unit 13. The emergency response unit is configured to disconnect the electrical connection between the control system and the power supply to shut down the cryogenic therapy device. For example, the emergency response unit may be an emergency stop button. When the emergency stop button is pressed, a pressed signal is transmitted to the drive control unit 13, which controls the power supply to be turned off, or the drive control unit 13 controls the power switch to be turned off to cut off the power supply.

[0063] Furthermore, the control system also includes a power button, which is communicatively connected to the drive control unit 13. When the power button is pressed, the drive control unit 13 controls the power switch to turn on to connect the power supply.

[0064] Furthermore, in this preferred embodiment, the control system includes a power management unit, and the power supply unit includes an analysis module and a voltage detection module and a current detection module that are communicatively connected to the analysis module; the analysis module is communicatively connected to the drive control unit; the voltage detection module is used to detect the voltage of each operating element and transmit the detection information to the analysis module; the current detection module is used to detect the current of each operating element and transmit the detection information to the analysis module; the analysis module performs analysis and processing based on the voltage and current of each operating element, and transmits the results of the analysis and processing to the drive control unit 13. When there is an abnormality in the voltage and current of each operating element analyzed by the analysis module, the drive control unit 13 transmits the abnormality information to the central processing unit 11, the central processing unit 11 transmits it to the display unit 10, and the alarm indicator light 102 lights up.

[0065] After receiving the information from the monitoring unit 12 and the drive control unit 13, if the information is abnormal or remains in an abnormal state for a long time, the central processing unit 11 will control the alarm indicator light on the display unit 10 to light up. The central processing unit 11 will analyze the information, generate a response strategy, issue instructions, and adjust the parameters of each component to restore the information to normal.

[0066] See Figure 3 The cryotherapy device also includes a body 31, on which an injection unit 25 is installed. A second pump 16 is located inside the body 1 and partially exposed. A heat exchanger 144 is also partially exposed to facilitate connection to a new extracorporeal circulation pipeline 15. A physiological parameter interface 26 is provided on the body 31 for easy connection to a first monitoring component for detecting physiological parameters. The physiological parameter interface 26 is an interface on the monitoring unit 12. A pipeline temperature sensor interface 27 is also provided on the body 31 for connection to a first temperature sensor 17 and a second temperature sensor 18. The pipeline temperature sensor interface 27 is an interface on the monitoring unit 12. A pipeline pressure sensor interface 28 is also provided on the body 31 for connection to a first pressure sensor 19 and a second pressure sensor 20. A liquid level sensor 29 (i.e., a liquid level detector) is also provided on the body 31 for detecting the liquid level. A bubble sensor 30 is also provided on the body 31 for detecting bubbles. A flow meter 34 is also provided on the body 31 for detecting the flow rate of the pipeline.

[0067] See Figure 4 The display 101 is connected to the fixed post 33 via a pivot 32, and the fixed post 33 is connected to the main body 31. The pivot 32 allows the display 101 to be adjusted, making it more convenient to use. The fixed post 33 can be a fixed column structure or a telescopic column for easy adjustment.

[0068] It should be noted that the structure of the above-mentioned cryotherapy device is merely a preferred configuration. This utility model does not impose any restrictions on the specific structure of the cryotherapy device, as long as it includes the various components and control system described in this utility model. Changes in the positional relationships between the various components do not deviate from the basic principles of this utility model and will fall within the protection scope of this utility model.

[0069] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
