Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a home-use ischemic preconditioning training device. Background Technology

[0002] Ischemic preconditioning training is a process that uses intelligent inflatable straps to repeatedly, briefly, and regularly apply and release pressure to the human body. This process organizes and promotes the body to produce endogenous anti-ischemic and hypoxic protective factors, enhancing the body's ability to adapt to potential future damage, thereby playing a preventive, improving, and protective role. Currently, home-use ischemic preconditioning training devices are available on the market. They are small in size, convenient to carry and use. For example, CN213310079U discloses an ischemic preconditioning training device, including a cuff and a control component set in a supporting shell. The control component includes a controller, an air pump, and a first electronic servo valve. The output end of the air pump is connected to one end of a guide tube via a three-way valve, and the other end of the guide tube is connected to the cuff. The other outlet of the three-way valve is connected to a main air tube that is closed at one end. A pressure sensor for monitoring air pressure is provided on the main air tube. The main air tube is connected to an exhaust pipe via a first branch pipe. One end of the exhaust pipe passes through an exhaust port on the supporting shell to discharge gas. A first electrical servo valve and a throttle valve for gas flow control are provided on the first branch pipe. The controller is connected to the air pump, the first servo valve, and the throttle valve respectively, and the controller controls their operation. This device trains the user for ischemic preconditioning through a control component. It not only allows for control of different pressures and times, making it suitable for different groups of people, but also enables one-button quantitative control of pressure and time, making it particularly suitable for the elderly. However, the cuff and control component are connected by an air tube. During daily life, the air tube, due to its long exposed design, can easily become tangled or used as a point of contact for handling, thus making it prone to breakage and affecting its use. Based on this, this invention designs a home-use ischemic preconditioning training device to solve the above problems. Utility Model Content

Equipped with an exhaust pipe, the mounting box has a miniature air pump, a first solenoid valve, and a second solenoid valve installed on the left side of its inner cavity. The outlet of the miniature air pump is connected to a metal conduit, a manual throttle valve, and the second solenoid valve via a branch pipe and a tee, respectively. The sensing end of the digital pressure gauge is sealed and inserted into the branch pipe. The outlet of the manual throttle valve is connected to the inlet of the first solenoid valve via a branch pipe. The outlets of the first and second solenoid valves are connected to the exhaust pipe via a branch pipe and a tee. A tray facing the rubber block is fixed to the inner wall of the mounting box. A rechargeable battery is installed on the tray. The rechargeable battery is electrically connected to a time relay and the miniature air pump via an aviation plug and a relay control circuit.

[0005] Preferably, a first manual switch and a second manual switch are installed at a distance from each other on the right side of the front surface of the mounting box. The first manual switch forms an electrical path with the first solenoid valve and the rechargeable battery through a wire, and the second manual switch forms an electrical path with the second solenoid valve and the rechargeable battery through a wire.

[0006] Preferably, a metal filter screen is installed at the outer port of the exhaust pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is equipped with a first solenoid valve and a manual throttle valve. The micro air pump is started for a certain period of time by a manual button in conjunction with a relay control circuit and a time relay. The pressure is determined by a digital pressure gauge. The gas is transmitted to the cuff to maintain a constant air pressure. The uniform compression of the cuff on the wrapped area achieves ischemia preconditioning. When depressurization is required, the first solenoid valve is activated by the first manual switch to release the gas in the pipeline from the exhaust pipe. The gas flow is controlled by the manual throttle valve to achieve gradual depressurization. In addition, since a second solenoid valve is set, the second manual switch controls the second solenoid valve to open, and the gas is directly discharged from the exhaust pipe. Therefore, the air pressure in the cuff is rapidly reduced. Furthermore, the first and second solenoid valves are connected in parallel and work independently without affecting each other. By slowly and quickly depressurizing the gas, different working conditions can be met. It is easy to adjust and suitable for home use. Moreover, the air tube is not too long, which can avoid breakage and makes it practical. Attached Figure Description

[0020] Please see Figure 1-3This utility model provides a technical solution: a home-use ischemic preconditioning training device, including a mounting box 1 with an arc-shaped bottom and densely covered with heat dissipation holes, which can conform to the body's curved surface for comfortable wear. A hollow cuff 2 is fixed to the bottom rear side of the mounting box 1, a common structure. A rectangular frame 3 is fixed to the bottom front side of the mounting box 1. A nylon fabric 4 is fixed to the outer end of the cuff 2, passing through the rectangular frame 3 and then attached to the outer wall of the cuff 2 via Velcro 5. Male and female Velcro fasteners are fixed to the nylon fabric 4 and the cuff 2 respectively, used to adjust the tightening length to cover the body. A rubber block 6 is inserted into the upper right side of the mounting box 1. A metal conduit 7, communicating with the upper part of the cuff 2, is installed through the middle rear side of the mounting box 1. A manual throttle valve 11, a digital pressure gauge 12, and a time relay 13 are inlaid at intervals on the left side of the front surface of the mounting box 1. An exhaust pipe 14 is installed at the rear left side of the mounting box 1, and a metal filter is installed at the outer port of the exhaust pipe 14 to prevent... To prevent debris from entering and clogging the system when not in use, a miniature air pump 15, a first solenoid valve 16, and a second solenoid valve 17 are installed on the left side of the inner cavity of the mounting box 1. The outlet of the miniature air pump 15 is connected to the metal conduit 7, the manual throttle valve 11, and the second solenoid valve 17 via a branch pipe and a tee, respectively. The sensing end of the digital pressure gauge 12 is sealed and inserted into the branch pipe for detecting system pressure. The outlet of the manual throttle valve 11 is connected to the inlet of the first solenoid valve 16 via a branch pipe. The outlets of the first solenoid valve 16 and the second solenoid valve 17 are connected to the exhaust pipe 14 via a branch pipe and a tee. A tray 18 is fixed to the inner wall of the mounting box 1, facing the rubber block 6. A rechargeable battery 19 is installed on the tray 18. The rechargeable battery 19 is electrically connected to the time relay 13 and the miniature air pump 15 via an aviation plug and a relay control circuit. The right side of the mounting box 1 has a power display that is electrically connected to the rechargeable battery 19 via a wire and an aviation plug, which is an existing power monitoring technology and can be charged in time.

[0021] Furthermore, a first manual switch 8 and a second manual switch 9 are installed at intervals on the right side of the front surface of the mounting box 1. The first manual switch 8 forms an electrical path with the first solenoid valve 16 and the rechargeable battery 19 through a wire, and the second manual switch 9 forms an electrical path with the second solenoid valve 17 and the rechargeable battery 19 through a wire, which facilitates manual operation.

[0022] Please see Figure 4 The relay control circuit includes a thermal relay FR1, a relay KM1, fuses FU1 and FU2, an emergency stop button SB1, and a manual button 10. The manual button 10 is also installed on the right side of the front surface of the mounting box 1. The working time is set by the time relay 13. After the manual button 10 is triggered, the relay KM1 will work for the set time. Then, the micro air pump 15 can work with the digital pressure gauge 12 to determine the air pressure inside the cuff 2. By setting different time periods, different air pressures can be easily adjusted.

[0023] When using this household ischemia preconditioning training device: The nylon cloth 4 drives the cuff 2, allowing the nylon cloth 4 to pass through the rectangular frame 3 and then be secured to the body using Velcro 5. A first solenoid valve 16 and a manual throttle valve 11 are installed. The manual button 10, in conjunction with the relay control circuit and time relay 13, controls the micro air pump 15 to start for a certain duration. The pressure is determined using a digital pressure gauge 12, and gas is transmitted to the cuff 2 to maintain a constant air pressure. The uniform compression of the wrapped area by the cuff 2 achieves ischemia preconditioning treatment. When entering… During depressurization, the first manual switch 8 is used to activate the first solenoid valve 16, allowing the gas in the pipeline to be discharged from the exhaust pipe 14. The gas flow rate is controlled by the manual throttle valve 11 to achieve gradual depressurization. In addition, since a second solenoid valve 17 is provided, the second manual switch 9 controls the second solenoid valve 17 to open, and the gas is discharged directly from the exhaust pipe 14. Therefore, the gas pressure in the cuff 2 is rapidly reduced. Furthermore, the first solenoid valve 16 and the second solenoid valve 17 are connected in parallel and work independently without affecting each other. By slowly and rapidly depressurizing the gas, different working conditions can be met.
