[0026] In order to reduce the number of inspections by medical staff, Figure 2 As shown, this embodiment provides an automatic bladder flushing device, comprising an infusion pipeline 1 and a drainage pipeline 2, wherein the infusion pipeline 1 is provided with a first pinch valve 10 and a first peristaltic pump 11 in sequence along the infusion direction; the drainage pipeline 2 is provided with a color sensor 20 for detecting the amount of blood in the liquid discharged from the bladder, a second peristaltic pump 21 and a second pinch valve 22 in sequence along the drainage direction;

[0027] Reference Figure 3 The present invention also includes a control unit 3, which is electrically connected to the first pinch valve 10, the second pinch valve 21, the first peristaltic pump 11, the second peristaltic pump 22 and the color sensor 20, and is used to control the on and off of the first pinch valve 10 and the second pinch valve 22, and control the operating speed of the first peristaltic pump 11 and the second peristaltic pump 21 based on the blood seepage value detected by the color sensor 20.

[0028] In actual use, the present invention allows the control unit 3 to control the on and off of the first pinch valve 10 and the second pinch valve 21, and controls the running speed of the peristaltic pump based on the amount of blood seepage detected by the color sensor 20, so as to adjust the infusion and drainage speeds, thereby reducing the number of inspections by medical staff and reducing the workload of medical staff.

[0029] In actual use, the control unit 3 controls the first pinch valve 10 to open, and then controls the first peristaltic pump 11 to operate, so that the infusion pipeline 1 can input liquid into the bladder for cleaning; in addition, the control unit 3 controls the second pinch valve 22 to open, and then controls the second peristaltic pump 21 to operate, so that the liquid in the bladder can be discharged.

[0030] In addition, in this embodiment, Figure 3 As shown, the control unit 3 is also electrically connected to a wireless communication unit 4 and a voice broadcast unit 5. The control unit 3 can send and receive data with a peripheral terminal through the wireless communication unit 4, wherein the wireless communication unit 4 can be a WIFI communication unit, and the control unit 3 emits a warning sound through the voice broadcast unit 5 for prompting.

[0031] In this embodiment, Figure 2As shown, the inlet of the infusion pipeline 1 is also connected to an infusion bag 13, and the infusion bag 13 is used to contain liquid for cleaning the bladder, and the cleaning liquid can be physiological saline.

[0032] When the bladder is actually cleaned, there is a difference between the temperature in the human body and the temperature of the liquid in the infusion bag 13. In order to make the temperature of the liquid infused into the bladder suitable, in this embodiment, Figure 2 As shown, a temperature control device 12 is further provided on the infusion pipeline 1 between the infusion bag 13 and the first pinch valve 10. The temperature control device 12 is used to detect the temperature of the liquid flowing out of the infusion bag 13, and heat the liquid flowing out of the infusion bag 13 when the detected temperature is lower than the set temperature. The temperature control device 12 is an existing temperature heating device, and no redundant description is given here.

[0033] Specifically, in this embodiment, the control unit 3 controls the first peristaltic pump 11 and the second peristaltic pump 21 in the following manner:

[0034] When the amount of blood seepage exceeds a set value, the control unit 1 speeds up the operation of the first peristaltic pump 11 and the second peristaltic pump 21, thereby speeding up the cleaning of the bladder.

[0035] In this embodiment, Figure 2 As shown, a pressure sensor 23 is also provided on the discharge pipeline 2 between the color sensor 20 and the second peristaltic pump 21. The control unit 3 is electrically connected to the pressure sensor 23. The pressure in the discharge pipeline 2 is detected by the pressure sensor 23, and an alarm message is sent to the peripheral terminal through the wireless communication unit 4 when the pressure in the discharge pipeline 2 exceeds the set pressure value. In addition, the control unit 3 can also send an alarm sound through the voice broadcast unit 5 to prompt medical staff.

[0036] In this example, Figure 2 As shown, a flow sensor 24 is also provided on the drainage pipeline 2, and the control unit 3 is electrically connected to the flow sensor 24. The flow sensor 24 detects the liquid flow in the drainage pipeline 2, and sends an alarm message to the peripheral terminal through the wireless communication unit 4 when the liquid flow is abnormal; in addition, the control unit 3 can also send an alarm sound through the voice broadcast unit 5 to prompt medical staff.

[0037] The peripheral terminal can be worn by medical staff, who can inspect patients after receiving the alarm information sent by the control unit 3 through the peripheral terminal. In addition, the peripheral terminal can be a handheld terminal that can receive the alarm information and give a prompt.

[0038] In a certain implementation, the peripheral terminal may be a host terminal, and the host terminal may be a computer.

[0039] In this example, Figure 2As shown, the outlet of the drainage pipeline 2 is also connected to a waste liquid bag 25, and the waste liquid bag 25 is used to store waste liquid flowing out of the bladder.

[0040] In this example, Figure 2 As shown, the present invention further includes a weighing device 26 for weighing the waste liquid bag 25. The control unit 3 is electrically connected to the weighing device 26, and obtains the weight information of the waste liquid bag 25 from the weighing device 26. When the weight of the waste liquid bag 25 exceeds the set weight, a weight warning message is sent to the peripheral terminal through the wireless communication unit 4. When the medical staff receives the weight warning message through the peripheral terminal, the waste liquid bag can be replaced; in addition, the control unit 3 can also send an alarm sound through the voice broadcast unit 5 to prompt the medical staff.

[0041] In the actual liquid discharge process, if the liquid discharge pipeline 2 is not blocked, the weight change rate of the heavy device 26 and the liquid flow rate detected by the flow sensor 24 are in a linear relationship, that is, the greater the liquid flow rate detected by the flow sensor 24, the greater the weight change rate of the heavy device 26, and the smaller the liquid flow rate detected by the flow sensor 24, the smaller the weight change rate of the heavy device 26; if the liquid discharge pipeline 2 is blocked, there is a difference between the weight change speed of the heavy device 26 and the liquid flow rate detected by the flow sensor 24;

[0042] Based on the relationship between the weight change rate of the heavy device 26 and the liquid flow detected by the flow sensor 24, in this embodiment, the control unit 3 obtains the weight change rate of the waste liquid bag 25 based on the weight information of the waste liquid bag 25, wherein the liquid flow abnormality is that the difference between the weight change rate and the liquid flow detected by the flow sensor 24 exceeds the set difference.

[0043] In summary, the present invention can realize automatic infusion and drainage of the bladder by setting up an infusion pipeline 1 and a drainage pipeline 2; in addition, by setting a color sensor 20, a pressure sensor 23 and a flow sensor 24 on the drainage pipeline 2 to detect the liquid discharged from the bladder, the number of inspections by medical staff can be reduced, and when an abnormality occurs during the process of bladder liquid discharge, the control unit 3 can prompt the medical staff through the wireless communication unit 4, so that the medical staff can check it in time.

[0044] The above is based on the present invention as an inspiration. Through the above description, relevant staff can make various changes and modifications without departing from the technical idea of ​​this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
