[0024] Figure 5 This application provides an automated arterial compression hemostasis method according to one embodiment. Detailed Implementation

[0025] Arterial bleeding is a critical situation during medical emergencies and surgeries. Traditional hemostasis methods primarily rely on manual pressure application by medical staff to control the bleeding. However, the stability of manual operation and precise pressure control are often difficult to guarantee, especially in emergency situations where medical staff may face time constraints, fatigue, or environmental interference, making manual hemostasis inherently risky. Furthermore, different patients have varying physiological differences in their pressure requirements, making it difficult for traditional methods to provide personalized adjustments.

[0026] With advancements in medical technology, automated and intelligent equipment is increasingly being used in various medical procedures. However, in the field of arterial compression hemostasis, there is still a lack of devices capable of real-time monitoring of blood flow and pressure, and automatically adjusting the compression intensity. Such a device not only needs precise control capabilities but also the ability to promptly alert or adjust in abnormal situations, thereby improving the success rate of hemostasis and reducing patient suffering and risks.

[0027] Therefore, this application proposes an arterial compression hemostasis device that reduces the risk of manual operation and improves the reliability of hemostasis and patient safety through real-time monitoring and precise control.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] Figure 1 This is a schematic diagram of the structure of an arterial compression hemostasis device provided in an embodiment of this application.

[0030] like Figure 1 As shown, the device includes the following structure: a central processing unit 10, a motor 20, and a compression module 30; the central processing unit 10 is connected to the motor 20, the motor 20 is connected to the compression module 30, and the compression module 30 is connected to the central processing unit 10.

[0031] The central processing unit 10 can refer to the core component of a computer or electronic device, responsible for executing instructions and processing data. In automated and intelligent devices, the central processing unit is the brain of the entire system; specifically, the central processing unit 10 is used to receive monitoring signals sent by the compression module 30, generate control signals based on the monitoring signals, and send the control signals to the motor 20.

[0032] The motor 20 can refer to a device that converts electrical energy into mechanical energy, and is a key actuator in various mechanical and electronic devices. In automated and intelligent equipment, the motor is mainly responsible for driving and controlling the movement of mechanical components. Specifically, the motor 20 receives control signals sent by the central processing unit 10 and rotates according to the control signals to pressurize or depressurize the pressure module 30.

[0033] The compression module 30 refers to a key component in automated and intelligent medical devices used to perform physical compression tasks. Specifically, in arterial compression hemostasis devices, the compression module is primarily responsible for applying appropriate pressure to a target area (such as an artery) to control or stop blood flow. The compression module 30 is used to generate monitoring signals and send these signals to the central processing unit 10.

[0034] Furthermore, in one possible implementation of this application, the compression module 30 further includes a silicone compression pad 31, a blood flow sensor 32, and a pressure sensor 33. The blood flow sensor 32 is located inside the silicone compression pad 31, and the pressure sensor 33 is connected to the silicone compression pad 31.

[0035] The silicone compression pad 31 is used to compress the user's artery; the blood flow sensor 32 is used to monitor the blood flow signal of the user's artery in real time, and the blood flow signal may include arterial filling degree, blood flow status, blood oxygenation at the hemostasis end and blood perfusion degree; the pressure sensor 33 is used to monitor the pressure value applied to the user's artery by the silicone compression pad 31 in real time.

[0036] It should be noted that the shape of the silicone compression pad 31 is not limited.

[0037] It should be noted that the blood flow sensor 32 typically operates based on ultrasound, Doppler effect, or optical technology. By transmitting signals into the blood vessel and receiving reflected signals, it can measure the speed and direction of blood flow. During arterial compression, the blood flow sensor provides real-time information on the blood flow status, helping the system adjust the compression intensity to ensure that while stopping bleeding, excessive compression is avoided, which could lead to a complete interruption of blood flow.

[0038] Preferably, the blood flow sensor 32 can be an LED light-emitting and receiving sensor or a dedicated blood flow monitoring sensor.

[0039] It should be noted that the pressure sensor 33 typically operates based on the principles of resistance, piezoelectricity, or capacitance. When external pressure is applied, the sensitive element inside the sensor deforms or undergoes other physical changes, generating an electrical signal proportional to the pressure, which is transmitted to the central processing unit 10 for analysis and processing. The pressure sensor 33 is used to measure the pressure value applied by the silicone compression pad 31 to the patient's skin or artery. It ensures that the pressure is maintained within a safe and effective range, avoiding excessively high or low pressure that could affect hemostasis or cause other complications.

[0040] In one embodiment of this application, the central processing unit 10 receives and processes user input or preset hemostasis parameters (such as target pressure and compression time). Based on these parameters, the central processing unit 10 sets the initial state of the compression module 30 and starts the motor 20. The motor 20 receives control signals from the central processing unit 10 and drives the silicone compression pad 31 in the compression module 30 to apply pressure to the artery. The motor 10 controls the compression force of the compression pad 31 by adjusting the drive current or voltage, ensuring that the pressure is gradually increased to a preset range. Then, the pressure sensor 33 measures the real-time pressure applied by the silicone compression pad 31 to the artery and feeds the data back to the central processing unit. Simultaneously, the blood flow sensor 32 monitors the blood flow status in the artery (such as flow velocity and flow rate) and feeds the data back to the central processing unit 10. The central processing unit 10 analyzes the data fed back by the sensor to determine whether the current compression effect meets the set standard. If the pressure sensor 33 detects insufficient or excessive pressure, the central processing unit 10 will issue an adjustment command to control the motor 20 to adjust the position and force of the silicone compression pad 31 to achieve the best compression effect. If the blood flow sensor 32 detects that the blood flow has not been effectively reduced or has been excessively reduced, the central processing unit 10 will also adjust the compression force according to the feedback signal to ensure that the blood flow reaches the set hemostasis target. Throughout the compression process, the central processing unit 10 continuously receives real-time data from the pressure sensor 33 and the blood flow sensor 32, and performs cyclical feedback adjustments. Through continuous monitoring and adjustment, the system ensures that the pressure during the compression process remains within a safe and effective range. When the central processing unit 10 determines that the bleeding has been effectively controlled and the set compression time or target has been reached, it issues a command to stop compression. The motor 20 controls the silicone compression pad 31 to gradually release the pressure, slowly loosening the compression to avoid sudden relaxation causing discomfort to the patient. After the compression ends, the central processing unit 10 uploads all process data (including pressure changes, blood flow, etc.) to the cloud server for subsequent analysis or medical recording.

[0041] This application provides an arterial compression hemostasis device that, through real-time monitoring and precise control, reduces the risks of manual operation and improves the reliability of hemostasis and patient safety.

[0042] Figure 2This is an interactive schematic diagram of an arterial compression hemostasis device and a terminal device provided in an embodiment of this application.

[0043] like Figure 2 As shown, the arterial compression hemostasis device can achieve wireless communication with terminal devices such as mobile phones.

[0044] In one implementation, the arterial compression hemostasis device also includes a Bluetooth transceiver module 40, which is equipped with a Bluetooth antenna for receiving and transmitting Bluetooth signals. The Bluetooth antenna is typically a small antenna used for wireless communication within the Bluetooth frequency band.

[0045] Once the device is paired with a mobile phone (or other terminal, which is not limited here), they can communicate via a Bluetooth antenna. The Bluetooth antenna receives Bluetooth signals from the mobile phone and transmits control commands to the Bluetooth transceiver module 40. At the same time, it can also transmit monitoring signals generated by the device to the mobile phone via the Bluetooth antenna.

[0046] Through the Bluetooth communication protocol, the device and the mobile phone can transmit monitoring signals and exchange control commands, thereby enabling interaction with external mobile devices and allowing the external devices to acquire monitoring signals at any time to determine the user's monitoring status.

[0047] Figure 3 This is a schematic diagram illustrating the interaction between an arterial compression hemostasis device and a cloud server, as provided in an embodiment of this application.

[0048] like Figure 3 As shown, the arterial compression hemostasis device can upload monitoring signals to the cloud server in real time.

[0049] In one implementation, the arterial compression hemostasis device further includes a wireless communication module 50, which is connected to the central processing unit 10 and is used to send monitoring signals to a cloud server.

[0050] For example, the wireless communication module can use transmission protocols such as WIFI, 4G, 5G, and Bluetooth to upload monitoring signals to a cloud server. The aforementioned cloud server can refer to a HIS system or a hospital's central monitoring system; this application does not limit this.

[0051] In this embodiment of the application, the device uploads the detection signal to the cloud server in real time through the wireless communication module, thereby enabling remote monitoring of the user and storage of the data corresponding to the user's monitoring signal for subsequent analysis or medical record use.

[0052] Figure 4 This is a schematic diagram of the structure of an arterial compression hemostasis device provided in another embodiment of this application.

[0053] like Figure 4 As shown, the compression module 30 in the arterial compression hemostasis device also includes a displacement sensor 34, which is connected to the silicone compression pad 31. The displacement sensor 34 is used to monitor the expansion and contraction of the silicone compression pad 31 in real time.

[0054] A displacement sensor 34 can refer to a sensor used to detect and measure the specific position or movement of an object or component. In automated and intelligent devices, displacement sensors help equipment determine the actual position of various mechanical parts to achieve precise control and adjustment.

[0055] Displacement sensors are used to detect the current position of critical components in a device. In an arterial compression hemostasis device, a displacement sensor might be used to detect the position of the silicone compression pad within the compression module to ensure accurate alignment with the artery and control the compression force. Furthermore, by continuously tracking the movement trajectory of the compression module, the displacement sensor can provide real-time positional feedback, ensuring precise execution of each movement.

[0056] In one example, the arterial compression hemostasis device also includes a display screen 60, which is connected to the central processing unit 10. The display screen 60 is used to obtain the blood flow signal and pressure value of the user's artery from the central processing unit 10, and display the blood flow signal and pressure value of the user's artery on the display screen 60. The display screen 60 is an LED display screen or an LCD display screen.

[0057] In this embodiment of the application, by adding a display screen to the arterial compression hemostasis device, the user's blood flow signal and pressure value and other related data can be displayed on the display screen in real time, so that the user can observe the arterial compression situation in real time.

[0058] In one example, the arterial compression hemostasis device also includes a button module 70, which is connected to the central processing unit 10. The button module 70 is used to output a power-on command or a power-off command to the central processing unit 10, and to output a control signal to the central processing unit 10.

[0059] For example, a power button is installed on the button module 70. When the button is pressed, the button module 70 sends a power on / off signal to the central processing unit 10. After receiving the signal, the central processing unit 10 can parse the signal and perform corresponding operations, such as turning the device on or off.

[0060] For example, a pressure button is installed on the button module 70. When the button is pressed, the button module 70 sends a pressure control signal to the central processing unit 10. After receiving the signal, the central processing unit 10 can analyze the signal and perform corresponding operations, such as controlling the pressure module 30 to increase or decrease pressure.

[0061] In one example, the arterial compression hemostasis device also includes an alarm module 80, which is connected to the central processing unit 10 and is used to send alarm alerts.

[0062] Furthermore, the alarm module 80 includes a microprocessor 81 and a speaker 82, which are connected together.

[0063] The microprocessor 81 is used to acquire the monitoring signal sent by the central processing unit 10 and determine whether the monitoring signal exceeds the preset condition range. If so, it sends an alarm control signal to the speaker 82.

[0064] The speaker 82 is used to control the speaker 82 to send an alarm reminder according to the alarm control signal.

[0065] For example, the microprocessor 81 receives monitoring signals sent by the central processing unit 10. The monitoring signals include blood flow signals and pressure values. When the blood flow signal or pressure value exceeds its respective preset range, the microprocessor 81 sends an alarm control signal to the speaker 82.

[0066] In this embodiment of the application, the alarm module can reduce the risks caused by equipment failure or improper operation and improve patient safety.

[0067] In one example, the arterial compression hemostasis device also includes a power module 90, which is connected to the central processing unit 10 and is used to supply power to the arterial compression hemostasis device.

[0068] The arterial compression hemostasis device provided in this application is applicable to an automated arterial compression hemostasis method.

[0069] like Figure 5 The embodiment shown in this application provides an automated arterial compression hemostasis method.

[0070] like Figure 5As shown, the first step involves the system acquiring relevant user information from the HIS system or user equipment, such as the user's medical history, current condition, and medical orders, based on the arterial compression hemostasis device. This information allows the system to understand the patient's specific needs and formulate a hemostasis plan accordingly. The second step involves controlling the LED light source of the blood flow sensor to emit light signals of a specific wavelength to detect subcutaneous blood flow. After the light signal is reflected or absorbed by the tissue, the blood flow sensor receives and records the returned light signal. The third step involves processing the received LED signals using algorithms to extract blood flow-related images or signals. Based on the processed data, the system calculates the user's current blood flow status, such as blood flow velocity and flow rate. The fourth step involves using a pressure sensor to acquire the pressure value applied to the artery in real time, while a displacement sensor detects the current compression amount of the compression module to ensure that the pressure is correctly applied to the target artery. The fifth step involves controlling the motor to operate according to the blood flow status and pressure value, allowing the compression module to apply pressure for hemostasis until the blood flow status and pressure value reach preset values, at which point the motor stops. The sixth step involves continuously monitoring blood flow and pressure to ensure stability throughout the entire hemostasis process. Step 7: After the preset compression time is reached, stop the compression operation of the compression module.
