Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically to a fluid-deficiency protection device for a uterine distension pump during hysteroscopic surgery. Background Art

[0002] Hysteroscopic surgery is a minimally invasive surgical technique that is commonly used to examine and treat female pelvic diseases, such as uterine fibroids, endometriosis, etc. During hysteroscopic surgery, a uterine distension pump is used to expand the uterine cavity, allowing doctors to observe the uterus and other pelvic organs more clearly.

[0003] Specifically, the uterine distension pump expands the uterine cavity by injecting a certain amount of fluid into the uterus to provide better visualization conditions. In this way, the doctor can use a hysteroscope (a slender optical instrument) to enter the uterine cavity, examine the condition of organs such as the uterus, fallopian tubes and ovaries, and perform necessary treatment.

[0004] However, during hysteroscopic surgery, if the infusion tube is short of fluid and the uterine distension pump fails to stop running, it may cause over-dilation of the uterus and increase the risk of uterine rupture. Therefore, during the operation, the status of the infusion tube needs to be checked frequently, which increases surgical interference and operation steps.

[0005] In order to solve the above problems, a fluid shortage protection device for a uterine distension pump is proposed, which automatically stops the operation of the uterine distension pump when there is a lack of fluid. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a fluid shortage protection device for uterine expansion pumps during hysteroscopic surgery.

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A fluid shortage protection device for a uterine distension pump during hysteroscopic surgery includes a uterine distension pump and an infusion tube connected to the uterine distension pump, the uterine distension pump is electrically connected to a smart socket, the infusion tube is provided with a fluid shortage sensor, the smart socket is connected to 220V AC power, and the smart socket is used to control the on and off of the uterine distension pump.

[0009] The liquid deficiency sensor comprises a shell and a microprocessor, a transmitter, a receiver and a communication module arranged inside the shell. A card block is arranged on the surface of the shell, and the liquid deficiency sensor is clamped on the infusion tube through the card block.

[0010] The transmitter transmits ultrasonic signals to the liquid to be tested in the infusion tube. When there are bubbles in the liquid, the ultrasonic signals will be reflected, scattered, and absorbed due to the presence of the bubbles. The receiver receives the reflected and scattered ultrasonic signals and sends the signals to the microprocessor. After receiving the signals, the microprocessor processes and judges whether the smart socket needs to be opened or closed. When the smart socket needs to be closed, a command is sent to the smart socket through the communication module.

[0011] As a further description of the above technical solution: a switch and a status indicator light are arranged on the shell, and the switch and the status indicator light are used to start and / or display the status of the liquid shortage sensor.

[0012] As a further description of the above technical solution: the shell has a built-in lithium battery and a charging management module, the lithium battery supplies power to the entire liquid deficiency sensor, the charging management module is used for charging management of the lithium battery, and a charging port is provided on the shell, and the charging port can charge the lithium battery through a USB adapter.

[0013] As a further description of the above technical solution: a buzzer is arranged on the shell, and the buzzer is connected to the microprocessor.

[0014] As a further description of the above technical solution: the shell has a built-in timer, the timer is connected to the microprocessor, the timer is used to collect and record the buzzing duration of the buzzer, and the smart socket responds according to the information collected by the timer.

[0015] As a further description of the above technical solution: the smart socket includes a wireless receiving module and a power switch, the wireless receiving module is used to receive instructions sent by the microprocessor through the communication module, and the power switch is used to open and close the smart socket.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] This solution uses a lack of fluid sensor to monitor the status of the infusion tube in real time and controls the start and stop of the uterine distension pump through the smart socket. When the lack of fluid sensor detects that the infusion tube is lacking fluid, the smart socket is turned off, and then the uterine distension pump is turned off, effectively protecting the endometrium from excessive expansion or damage. During the operation, the automatic stop of the uterine distension pump by the smart socket can enable the surgical team to focus more on the surgical operation, reduce the frequent inspection and intervention of the infusion status, which can simplify the operation steps and improve the efficiency of the operation.

The smart socket 3 comprises a wireless receiving module 31 and a power switch 32, the wireless receiving module 31 is used to receive instructions sent by a microprocessor 42 through a communication module 45, the power switch 32 is used to open and close the smart socket 3, and an LED light is provided on the smart socket 3 to display the state of the smart socket 3.

[0026] The operation method of the smart socket 3 is as follows:

[0027] a. Pairing operation

[0028] After the socket is plugged in, turn off the socket first (LED light is off), press and hold the switch button on the socket for 2 seconds, and the indicator light on the socket flashes (once per second) to indicate that it is in pairing mode. At this time, release the button on the socket and press the switch key of the liquid shortage sensor 4. The socket receives the remote control signal sent by the liquid shortage sensor 4. When the pairing is successful, the indicator light on the socket flashes quickly for 1 second and then goes out.

[0029] b. The socket can support the control of multiple liquid shortage sensors 4. Repeat the pairing operation steps in sequence to add other bubble sensors.

[0030] c. Cancel pairing

[0031] After the socket is plugged in, turn off the socket first (LED light is off), press and hold the button on the socket, at this time the indicator light on the socket will flash once per second, continue to hold the button on the socket, then the indicator light will flash quickly, and then go out, indicating that the liquid shortage sensor 4 originally configured on the socket has been cleared, and needs to be re-paired if needed later.

[0032] like Figure 2-4 As shown, the lack of liquid sensor 4 includes a housing 41 and a microprocessor 42, a transmitter 43, a receiver 44 and a communication module 45 arranged inside the housing 41. The communication module 45 is, for example, a Wi-Fi module or a Bluetooth module. A card block 51 is arranged on the surface of the housing 41 of the communication module 45, and the lack of liquid sensor 4 is clamped on the infusion tube 2 through the card block 51.

[0033] The transmitter 43 transmits ultrasonic signals to the liquid to be tested in the infusion tube 2. When there are bubbles in the liquid, the ultrasonic signals will be reflected, scattered, and absorbed due to the presence of the bubbles. The receiver 44 receives the reflected and scattered ultrasonic signals and sends the signals to the microprocessor 42. After receiving the signals, the microprocessor 42 processes and judges whether the smart socket 3 needs to be opened and closed. When the smart socket 3 needs to be closed, a command is sent to the smart socket 3 through the communication module 45.

[0034] The housing 41 is also provided with a switch and a status indicator 46 and a buzzer 49. The switch and status indicator 46 are used to start and / or display the status of the liquid shortage sensor 4.

The housing 41 is provided with a charging port 52, which can charge the lithium battery 47 through a USB adapter. The timer 50 is connected to the microprocessor 42. The timer 50 is used to collect and record the duration of the buzzer 49. The smart socket 3 responds according to the information collected by the timer 50.

[0035] The bubble sensor works as follows:

[0036] a. Charging

[0037] Plug in the charger to start charging. During the charging process, the red indicator light of the switch and the status indicator light 46 flashes, and the indicator light stays on after it is fully charged.

[0038] b. Start and stop monitoring

[0039] Click the button on the liquid shortage sensor 4 to start or stop the bubble detection. When the detection starts, the smart socket 3 is powered on by remote control, and the green light indicator flashes once per second. If there are bubbles, the buzzer 49 beeps twice per second to remind. When there is liquid, the beeping stops and the detection continues.

[0040] Once there is no liquid for 10 consecutive seconds, the buzzer 49 will beep 10 times in succession and remotely shut down the power supply of the smart socket 3. After the beeping ends, the liquid shortage sensor 4 stops working and the green indicator light stops flashing.

[0041] During the bubble monitoring process, the green indicator light will flash continuously. Once the monitoring is stopped, the green indicator light will go out.

[0042] The above is a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical solution and its improved conception of the utility model, which should be included in the protection scope of the utility model.
