Description

Technical Field

[0001] The utility model relates to the technical field of sphygmomanometers, in particular to an ischemic preconditioning training instrument. Background Art

[0002] Preconditioning trainers achieve fitness and rehabilitation by wrapping the proximal end of a limb with a cuff or bandage to maintain arterial inflow while blocking venous return during exercise. Existing pre-adaptation training devices, such as the invention patent application with publication number CN104644147A, disclose an ischemic pre-adaptation therapeutic device, which has the following problems: (1) The left air pump, right air pump, left solenoid valve, right solenoid valve, and air release valve used for left and right arm training are connected together through a five-way device. When training both arms, the left solenoid valve and the right solenoid valve are both open, and the entire air path is completely connected, making it impossible to adjust and control the pressure on one side alone; (2) There is no mutual coordination between the blocking and pressurizing components between the left and right arms, making it impossible to compare the left and right arms under the same conditions; (3) When training or testing a single arm, only one side of the air pump needs to work. For example, when the left air pump is working and pressurizing, not only the air pipe of the left training component needs to be filled with gas, but also the air pipes of other components such as the right air pump on the five-way device need to be filled with gas. Therefore, the inflation speed is relatively slow during unilateral testing, and the components on both sides are completely connected, making it impossible to test the left and right arms at different pressures at the same time.

The other two ports of the left three-way connector are respectively connected to the left airbag and the left pressure sensor through hoses. The left airbag is used to store gas and maintain the state of applying pressure to the left arm; the left pressure sensor is close to the left airbag and is connected to the MCU control unit through a circuit. The left pressure sensor is used for detecting the blocking pressure of the left arm and transmitting the pressure value to the MCU control unit.

[0030] As Figure 2 shown, in addition to the above modules, the training instrument further includes a blood oxygen module, a touch keypad, an LCD display screen, a Bluetooth module, a Wifi module, a buzzer, and a power supply module. The blood oxygen module is connected to the MCU control unit through a serial port. Among them, as Figure 5 shown, the blood oxygen module mainly monitors indicators such as blood oxygen saturation and blood perfusion index during block training. This module can use existing mature products on the market or be independently developed according to specific requirements. The touch keypad is connected to the MCU control unit through a serial port. The touch keypad is mainly used for parameter setting and function selection. In this embodiment, it includes an up key "∧", a down key "∨", a setting key "SET", a mode selection key "MODE", a power on / off key "◎", etc. The LCD display screen is connected to the MCU control unit through a circuit. The LCD display screen is mainly used to display the values of various parameters such as training time, training times, training mode, blood oxygen saturation, blood perfusion index, heart rate, and block pressure. As Figure 4As shown, the Bluetooth module and the Wifi module are used for wireless communication with mobile devices. The buzzer is connected to the MCU control unit through a circuit and can emit a prompt sound or an alarm. The power module includes a power management system, a lithium battery, and a charger. The charger is connected to the lithium battery and is used to charge the lithium battery. The lithium battery is connected to the MCU control unit, the LCD display screen, and each solenoid valve through the power management system and is used to provide working power. Since the power supply voltages required by the MCU control unit, the LCD display screen, and the solenoid valves are different, the lithium battery outputs a DC voltage that meets the requirements of each component through the power management system for power supply.

[0031] Working process:

[0032] When training: First, wrap the left airbag 60 and the right airbag 61 around the left arm and the right arm respectively, turn on the power key "◎", and then select the training mode by touching the "MODE" key on the keypad. Taking the left arm training component 100 as an example to illustrate the action process of each solenoid valve. At this time, the MCU control unit controls the left air release normally open solenoid valve 20, the left exhaust normally open solenoid valve 30, and the left normally open direct-through solenoid valve 40 to close, and connects the gas path between the left air pump motor 50 and the left airbag 60. The MCU control unit controls the left air pump motor 50 to start inflating the left airbag 60. The left pressure sensor 10 monitors the pressure of the left airbag 60. When the pressure of the left airbag 60 reaches the pressure required for training, the pressure value is fed back to the MCU control unit. The MCU control unit controls the left air pump motor 50 to stop inflating the left airbag 60 according to the pressure value. At the same time, the left normally open direct-through solenoid valve 40 is disconnected to prevent gas leakage from the left air pump motor 50 side, so that the left airbag 60 maintains this pressure for a certain period of time to achieve block training. Then the MCU control unit controls the left air release normally open solenoid valve 20 to open, so that the left airbag 60 gradually deflates. Then the above processes of inflation and deflation are repeated, and the training times and training time are recorded. During the training process, the blood oxygen module monitors indicators such as blood oxygen saturation and blood perfusion index, and stores the test data under the name of the corresponding trainee for viewing the training effect after a period of training. At the same time, the heart rate, blood pressure, etc. are also monitored. All the monitored data are sent to the MCU control unit and are transmitted by the MCU control unit to the LCD display screen for display. When the training is completed, the MCU control unit controls the left exhaust normally open solenoid valve to open, so that all the gas in the left airbag 60 is discharged, thus completing a block training. The training process of the right arm is basically the same as that of the left arm and will not be elaborated here.

[0033] The MCU control unit can control the left arm training component 100 and the right arm training component 200 to work simultaneously, or can control the left arm training component 100 and the right arm training component 200 to work independently, enhancing the adaptability of training.

[0034] In addition, generally speaking, due to physiological and anatomical reasons, there are certain differences in the blood pressure values measured in the left upper arm and the right upper arm, but generally they do not exceed 10 mmHg. Whether suffering from hypertension or not, if the difference in the measured blood pressure values on both sides is too large, exceeding 10 mmHg, especially exceeding 20 mmHg, it may be a pathological condition. Therefore, by monitoring the blood pressure difference measured on the left and right arms under the same conditions, pathological conditions such as hypertension can be detected in a timely manner, so as to carry out effective monitoring and treatment.

[0035] Inspired by the ideal embodiments of the present invention based on the above, through the above description, relevant staff can completely make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
