Description

Technical Field

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. Its prerequisite is a reliable vascular access. Arteriovenous fistula is the main vascular access for patients with maintenance hemodialysis. Patients should check the fistula every day for abnormalities to prevent infection or vascular occlusion.

[0003] Generally, after the hemodialysis is over, patients need to use cotton balls and paper rolls to press and stop bleeding under the guidance of medical staff to ensure that the puncture site heals in time. However, some patients are eager to leave the hospital after the hemodialysis is over, and can only loosen the fistula on their own without the guidance of medical staff. If the force is too small or the time is too short, it will cause bleeding. Blood extravasation will cause panic and blood loss in patients. Most dialysis patients are anemic, and blood seeping into the subcutaneous tissue will cause subcutaneous hematoma. The skin will appear cyanotic the next day, which will make the next puncture difficult and affect the function of blood vessels. If the force is too large or the time is too long, the blood flow of the fistula may be blocked, causing obstruction.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0021] At present, after the hemodialysis, patients need to use cotton balls and paper rolls to press and stop bleeding under the guidance of medical staff to ensure that the puncture site heals in time. However, some patients are eager to leave the hospital after the hemodialysis, and can only loosen the fistula on their own without the guidance of medical staff. If the force is too small or the time is too short, it will cause bleeding. Blood extravasation will cause panic and blood loss in patients. Most dialysis patients are anemic, and blood seeping into the subcutaneous tissue will cause subcutaneous hematoma. The skin will appear purple the next day, which will make the next puncture difficult and affect the function of blood vessels.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0026] See also Figure 1 As shown, Figure 1 This is one of the structural schematic diagrams of the fistula-releasing device provided in an embodiment of the present application. The fistula-releasing device 100 includes a control end 101 and a patient information import device 102 and a fistula-releasing device 103 which are communicatively connected to the control end. The fistula-releasing device 103 includes a driving motor 1031, a bleeding point sensor 1032, a pressure sensor 1033, and a blood pressure measuring device 1034.

[0027] The patient information importing device is used to import body parameters related to the healing of the puncture point.

[0028] Physical parameters include at least: age, gender, height, weight, coagulation function-related parameters, blood lipid-related parameters, blood sugar-related parameters, number of dialysis sessions, dialysis duration, whether the patient is anemic, diabetic, or hypertensive, and whether the patient has ever received treatment for loose fistula.

[0029] The driving motor is used to pressurize or reduce the pressure at the puncture point.

[0030] The pressure sensor is used to collect the pressure value between the drive motor and the puncture point.

[0031] The bleeding point sensor is used to collect the bleeding area of ​​the puncture point.

[0032] The blood pressure measuring device is used to collect the blood pressure value at the puncture point.

[0033] The control end is connected to the drive motor, the bleeding point sensor, the pressure sensor, and the blood pressure measuring device. The patient information importing device sends the imported body parameters to the control end; the pressure sensor sends the collected pressure value to the control end; the bleeding point sensor sends the collected bleeding area to the control end, or the bleeding point sensor sends the collected data containing the bleeding area information to the control end, and the control end extracts the bleeding area from the received data; the blood pressure measuring device sends the collected blood pressure value to the control end; the control end is used to control the drive motor to pressurize or depressurize the puncture point according to the body parameters, bleeding area, and blood pressure value with the help of the pressure sensor.

[0034] There are three working modes when the control end controls the driving motor to pressurize (depressurize) the puncture point. Working mode 1: Determine the pressing pressure value, pressing duration, buffer pressure value, and buffer duration for the puncture point according to the patient's physical parameters; Working mode 2: Determine the pressure increase value according to the bleeding area, and adjust the pressing pressure value and buffer pressure value; Working mode 3: Determine the pressure increase value or pressure reduction value according to the blood pressure value, and adjust the pressing pressure value and buffer pressure value.

[0035] Working mode 1: The control end is used to determine the pressing pressure value, pressing time, buffer pressure value and buffer time of the puncture point according to the imported body parameters; control the drive motor to pressurize the puncture point, and when the pressure value measured by the pressure sensor is the pressing pressure value, control the drive motor to stop pressurizing; after the pressing time, control the drive motor to decompress the puncture point, and when the pressure value measured by the pressure sensor is the buffer pressure value, control the drive motor to stop decompressing; after the buffer time, control the drive motor to decompress the puncture point, and when the pressure value measured by the pressure sensor is zero, control the drive motor to stop decompressing.

[0036] After completing dialysis, taking the correct compression hemostasis method is an important way to protect the fistula. In this process, attention should be paid to the compression time, strength and compression point. After completing dialysis, first press the puncture point with the compression pressure value. After the compression time is reached, press the puncture point with the buffer pressure value. After the buffer time is reached, the puncture point is released.

[0037] Due to the different physical conditions of different patients, the compression time and strength of the puncture point are also different. In order to better adapt to the patient's physical condition and improve the accuracy of loose fistula, the pressing pressure value, pressing duration, buffer pressure value, and buffer duration that meet the patient's physical condition are calculated according to the patient's physical parameters. As a possible implementation method, the weight of each body parameter is set. Assuming that the body parameters are X1, X2, X3, and X4, respectively, when calculating the pressing pressure value, the weights of the body parameters are k1, k2, k3, and k4, respectively, and the calculation result of X1×k1+X2×k2+X3×k3+X4×k4 is used as the pressing pressure value; when calculating the pressing duration, the weights of the body parameters are g1, g2, g3, and g4, respectively, and the calculation result of X1×g1+X2×g2+X3×g3+X4×g4 is used as the pressing duration. As another possible implementation, the physical parameters of several patients, as well as the compression pressure value, compression duration, buffer pressure value, and buffer duration of the patients when loosening their fistulas are collected, and the collected data are used as model training parameters to train the calculation model of the fistula loosening compression time and compression intensity. The control end inputs the patient's physical parameters into the trained model to obtain the compression pressure value, compression duration, buffer pressure value, and buffer duration output by the model.

[0038] Optionally, a fixed pressing pressure value, pressing time, buffer pressure value, and buffer time are set to press the puncture point, for example, the pressing time is 15 minutes and the buffer time is 10 minutes.

[0039] Working mode 2: The control end is also used to determine a first pressure increase value according to the bleeding area collected by the bleeding point sensor, control the drive motor to pressurize the puncture point, and control the drive motor to stop pressurizing when the pressure value measured by the pressure sensor increases by the first pressure increase value.

[0040] When pressing the puncture point, if the force is too small or the time is too short, it will cause bleeding. Blood extravasation will cause panic and blood loss in patients. Most dialysis patients are anemic. Blood seeping into the subcutaneous tissue will cause subcutaneous hematoma. The skin will appear cyanotic the next day, which will make the next puncture difficult and affect vascular function. If the bleeding area detected by the bleeding point sensor is zero, there is no need to change the pressure value of the puncture point; if the bleeding area detected by the bleeding point sensor is greater than zero, the first pressure increase value is determined according to the bleeding area. The larger the bleeding area, the greater the first pressure increase value. If the driving motor currently presses the puncture point with a pressing pressure value F1, after detecting the bleeding area, the first pressure increase value F2 corresponding to the bleeding area is calculated, and the driving motor presses the puncture point with a new pressing pressure value (F1+F2); if the driving motor currently presses the puncture point with a buffering pressure value F3, after detecting the bleeding area, the first pressure increase value F4 corresponding to the bleeding area is calculated, and the driving motor presses the puncture point with a new buffering pressure value (F3+F4).

[0041] Working mode three: The control end is also used for determining a pressure reduction value based on the collected blood pressure value if the blood pressure value at the puncture point collected by the blood pressure measuring device is greater than the upper limit of the blood pressure, controlling the drive motor to decompress the puncture point, and controlling the drive motor to stop decompressing when the pressure value measured by the pressure sensor is reduced by the pressure reduction value; if the blood pressure value at the puncture point collected is less than the lower limit of the blood pressure, determining a second pressure increase value based on the collected blood pressure value, controlling the drive motor to pressurize the puncture point, and controlling the drive motor to stop pressurizing when the pressure value measured by the pressure sensor is increased by the second pressure increase value.

[0042] When pressing the puncture point, too little or too much pressure will affect the healing of the puncture point. The blood pressure value near the puncture point can reflect whether the pressure is appropriate to a certain extent. If the blood pressure value is greater than the upper limit of blood pressure, the pressure needs to be reduced. If the blood pressure value is less than the lower limit of blood pressure, the pressure needs to be increased.

[0043] Taking the blood pressure value being greater than the upper limit of the blood pressure as an example for specific explanation, if the driving motor currently presses the puncture point with the pressing pressure value F5, when it is detected that the blood pressure value is greater than the upper limit of the blood pressure, the pressure reduction value F6 corresponding to the current blood pressure value is calculated, and the larger the blood pressure value, the larger the pressure reduction value, and the driving motor presses the puncture point with the new pressing pressure value (F5-F6); if the driving motor currently presses the puncture point with the buffer pressure value F7, when it is detected that the blood pressure value is greater than the upper limit of the blood pressure, the pressure reduction value F8 corresponding to the current blood pressure value is calculated, and the driving motor presses the puncture point with the new buffer pressure value (F7-F8).

[0044] The fistula loosening device provided in the embodiment of the present application can determine the pressing pressure value, pressing time, buffer pressure value, and buffer time that are consistent with the patient's current physical condition according to the patient's physical parameters, blood pressure values, and bleeding area, and use the above parameters to control the driving motor to press the puncture point, thereby achieving customized fistula loosening for the patient and improving the accuracy and safety of fistula loosening.

[0045] For further information, see Figure 2 As shown, Figure 2 The second structural schematic diagram of the fistula device provided in the embodiment of the present application, the fistula device 200 includes a control terminal 201 and a patient information import device 202, a fistula device 203, and a fistula device 204 that are communicatively connected to the control terminal, the fistula device 203 includes a driving motor 2031, a blood leakage point sensor 2032, a pressure sensor 2033, and a blood pressure measuring device 2034, and the fistula device 204 includes a driving motor 2041, a blood leakage point sensor 2042, a pressure sensor 2043, and a blood pressure measuring device 2044. The fistula device 203 and the fistula device 204 are respectively placed at the bleeding puncture point and the blood return puncture point. The control terminal 201 generates control data of the driving motor 2031 and the driving motor 2041 according to the bleeding puncture point and the blood leakage area and blood pressure value of the blood return puncture point returned by the fistula device 203 and the fistula device 204.

[0046] For further information, see Figure 3 As shown, Figure 3 This is the third structural schematic diagram of the fistula loosening device provided in the embodiment of the present application. The fistula loosening device 100 further includes a target pressure input device 104 and a target duration input device 105 .

[0047] The target pressure input device is used to import the target pressure value set by the user.

[0048] The target duration input device is used to import the target duration set by the user.

[0049] The control end is also used to control the drive motor to transform the pressure at the puncture point. When the pressure value measured by the pressure sensor is the target pressure value, the drive motor is controlled to stop transforming the pressure. After the target time has passed, the drive motor is controlled to decompress the puncture point. When the pressure value measured by the pressure sensor is zero, the drive motor is controlled to stop decompressing the pressure.

[0050] The control end can automatically adjust the pressure of the drive motor according to the above-mentioned working mode 1, working mode 2, and working mode 3, and can also adjust the pressure according to user requirements. The user inputs the target pressure value and target duration through the target pressure input device and the target duration input device, and the control end controls the drive motor to press the puncture point for the target time with the target pressure value.

[0051] As a possible implementation manner, the target pressure input device is a manual pressure regulator, and the target duration input device is a manual duration regulator to achieve manual adjustment; as another possible implementation manner, the target pressure input device and the target duration input device are both voice interaction devices to achieve voice adjustment.

[0052] Furthermore, the fistula loosening device includes a plurality of driving motors.

[0053] The bleeding point sensor is also used to collect the bleeding position of the puncture point.

[0054] The control end is also used to select a target drive motor corresponding to the bleeding position from the multiple drive motors according to the bleeding position of the puncture point, and control the target drive motor to pressurize the bleeding position.

[0055] The bleeding point sensor sends the collected bleeding position to the control end, or the bleeding point sensor sends the collected data containing the bleeding position information to the control end, and the control end extracts the bleeding position from the received data. If the bleeding area is small, the pressing area of ​​the drive motor is larger than the bleeding area, and pressurizing the entire pressing area will cause excessive pressure on the non-leaking area, which may block the blood flow of the fistula and cause blockage. Therefore, multiple drive motors are provided, and the target drive motor selected according to the bleeding position can accurately pressurize the bleeding position and improve the accuracy of loosening the fistula at the puncture point.

[0056] For further information, see Figure 4 As shown, Figure 4 This is the fourth structural schematic diagram of the fistula loosening device provided in the embodiment of the present application. The fistula loosening device 100 also includes an information prompting device 106 .

[0057] The control end is also used to determine whether the patient is suitable for using the fistula loosening device based on the body parameters; if suitable, the pressing pressure value, pressing time, buffer pressure value, and buffer time of the puncture point are determined based on the body parameters; otherwise, a prompt message is sent to the information prompt device indicating that the patient is not suitable for using the fistula loosening device and it is recommended that the patient stay in the hospital to loosen the fistula.

[0058] If the patient has poor coagulation function, anemia, diabetes, hypertension, has received treatment for fistula loosening, and is not suitable for self-loosening of fistula using a fistula loosening device, he should loosen his fistula under the guidance of medical staff, or receive fistula loosening treatment. The control end conducts a comprehensive analysis based on the patient's physical parameters. If the patient is not suitable for using the fistula loosening device, the control end sends a prompt message to the information prompt device that the patient is not suitable for using the fistula loosening device and it is recommended to stay in the hospital for fistula loosening. The information prompt device displays the received prompt message to improve the safety of the patient's fistula loosening.

[0059] For further information, see Figure 5 As shown, Figure 5 This is the fifth structural schematic diagram of the fistula loosening device provided in the embodiment of the present application. The fistula loosening device 103 also includes a frequency sensor 1035 for collecting the frequency of the internal fistula blood vessel.

[0060] The control end is also used to determine the pressure change value according to the vibration frequency of the internal fistula blood vessel if the vibration frequency collected is greater than the upper limit of the vibration frequency, or less than the lower limit of the vibration frequency, and control the drive motor to transform the pressure at the puncture point; when the pressure value measured by the pressure sensor changes by the pressure change value, control the drive motor to stop transforming the pressure.

[0061] In practice, the pressure control at the puncture point should be based on the condition that there is no bleeding at the puncture point and the fistula blood vessel tremors can be felt. If the vibration frequency of the fistula blood vessel exceeds the upper limit of the vibration frequency, or is lower than the lower limit of the vibration frequency, the pressure value of the drive motor on the puncture point is changed until the vibration frequency of the fistula blood vessel is within the range of the upper limit of the vibration frequency and the lower limit of the vibration frequency.

[0062] For further information, see Figure 6 As shown, Figure 6 The sixth structural diagram of the fistula-relaxing device provided in the embodiment of the present application, the fistula-relaxing device 100 further includes an alarm device 107; The controller is also used to send abnormal frequency alarm information of the internal fistula blood vessel to the alarm device if the collected frequency of the internal fistula blood vessel is greater than the upper limit of the frequency, or less than the lower limit of the frequency.

[0063] When the vibration frequency of the internal fistula blood vessel is abnormal, the control end controls the alarm device to alarm to improve the safety of the patient's fistula release.

[0064] Furthermore, the control terminal is also used to send all the loosening data to the user terminal after the loosening of the fistula at the puncture point is completed. The loosening data is stored to facilitate the mastery of the patient's treatment data.

[0065] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
