DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide an endoscope-assisted water supply device to solve the problems existing in the above-mentioned related technologies, so that the endoscope-assisted water supply device can detect whether the pump head is detached, thereby improving the safety factor of the use of the endoscope-assisted water supply device.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1

[0034] This embodiment provides an endoscope auxiliary water delivery device, please refer to Figure 1-Figure 7 , including a host 1 and a kettle 2, wherein the host 1 includes a shell 14, a peristaltic pump and a detection mechanism 8, the pump head 4 of the peristaltic pump is located outside the shell 14 and is detachably connected to the shell 14, and the detection mechanism 8 can monitor the connection status of the pump head 4 and the shell 14; the kettle 2 can accommodate flushing liquid, the kettle 2 is connected to the hose 3 of the peristaltic pump, and the driver 9 of the peristaltic pump can squeeze the hose 3 to achieve the purpose of conveying the flushing liquid in the kettle 2 and adjusting the flow rate.

[0035] In the endoscope auxiliary water delivery device of the present invention, the peristaltic pump of the host 1 can deliver the flushing liquid in the kettle 2 to the endoscope observation area to achieve the purpose of flushing the endoscope. The detection mechanism 8 can monitor the connection between the pump head 4 of the peristaltic pump and the housing 14, thereby achieving the purpose of detecting whether the pump head 4 of the peristaltic pump is detached, improving the reliability of flushing liquid delivery, and enhancing the safety factor of the use of the endoscope auxiliary water delivery device.

[0036] It should also be noted that, in practical applications, the driver 9 may be a motor, which squeezes the hose 3 to deliver the flushing liquid.

[0037] In this specific embodiment, the detection mechanism 8 includes a mechanical button 15, which is slidably connected to the housing 14 and can be extended from the housing 14. An elastic element is arranged between the mechanical button 15 and the housing 14. When the pump head 4 is connected to the housing 14, the mechanical button 15 can be pushed to slide and change the deformation of the elastic element. When the pump head 4 is separated from the housing 14, the mechanical button 15 is reset under the elastic force of the elastic element. When the pump head 4 is not connected to the housing 14, the mechanical button 15 is in a pop-up state. After the pump head 4 is connected to the housing 14, the mechanical button 15 is squeezed. After the pump head 4 is installed in place, the mechanical button 15 is in a retracted state. The connection between the pump head 4 and the housing 14 can be monitored by the state of the mechanical button 15, and then it can be judged whether the pump head 4 falls off. For example, after the pump head 4 falls off, the mechanical button 15 resumes the pop-up state under the elastic force of the elastic element. When the mechanical button 15 is detected to be in the pop-up state, it can be judged that the pump head 4 has fallen off.

[0038] It should also be noted that the host 1 also includes a control module 11, and the peristaltic pump and the detection mechanism 8 are both in communication connection with the control module 11, and the control module 11 is disposed in the housing 14. After the detection mechanism 8 detects that the pump head 4 has fallen off and transmits the information of the pump head 4 falling off to the control module 11, the control module 11 controls the peristaltic pump to turn off, thereby improving the working reliability of the device. The control module 11 is used to control the working state of the peristaltic pump to adjust the flow rate of the flushing liquid and other parameters to ensure that the device meets the flushing needs of the endoscope. It should also be explained here that the pop-up and retracted state information of the mechanical button 15 can be transmitted to the control module 11 using a proximity switch. For example, when the mechanical button 15 is retracted into the housing 14, the proximity switch is triggered, and the proximity switch transmits the retracted state signal of the mechanical button 15 to the control module 11. In this specific embodiment, the control module 11 receives input signals, processes data, and outputs corresponding control instructions through built-in software and hardware logic to ensure that the equipment operates safely and efficiently according to a predetermined program. It includes a microprocessor, a sensor interface, and a communication interface 12. The structural composition and working principle of the control module 11 are common knowledge to those skilled in the art and will not be repeated here.

[0039] In order to facilitate input of control information and to obtain the working status of the device, the host 1 is further provided with a key module 5 and a display module 6, which are arranged on the housing 14, and are both in communication connection with the control module 11. The key module 5 and the display module 6 are both components in the host 1 for interacting with the user, the key module 5 is used to receive user instructions, and the display module 6 is used to display information and feedback.

[0040] At the same time, the host 1 also includes a power supply module 10, which can convert AC power into DC power, and ensure the output of stable DC voltage and current through internal rectification, filtering and voltage stabilization circuits to power the host 1. The power supply module 10 is electrically connected to the driver 9 to ensure the normal operation of the peristaltic pump. The power supply module 10 is arranged in the shell 14, and the power supply module 10 is provided with a power switch 7 to facilitate the control of the power on and off.

[0041] In addition, the host 1 also includes a communication interface 12 and a foot switch interface 13. The host 1 can use the communication interface 12 to communicate with external devices to achieve communication with external devices and host 1 software upgrades; the foot switch interface 13 can connect to a foot switch and receive a foot switch pressing signal, thereby achieving the use of the foot switch to control the working state of the host 1 and improve the operating convenience of the device.

[0042] Specifically, the housing 14 is connected to a supporting plate, and the kettle 2 is arranged on the supporting plate, so that the kettle 2 and the host 1 can move simultaneously, thereby improving the convenience of operation and use of the endoscope-assisted water delivery device; in practical applications, the supporting plate can be of a U-shaped structure to ensure the stability of the kettle 2. In practical applications, an anti-skid pad can also be arranged on the supporting plate to increase the sliding friction coefficient between the supporting plate and the kettle 2, thereby ensuring the structural stability of the kettle 2 and improving the reliability of the endoscope-assisted water delivery device.

[0043] In other specific embodiments that can be realized by the present invention, the shell 14 and the supporting plate are detachably connected to facilitate disassembly and assembly, and supporting plates of different specifications can be replaced according to the actual specifications and placement requirements of the kettle 2.

[0044] It should also be noted that the housing 14 is a split structure, which facilitates the disassembly and assembly of components and provides convenient conditions for the inspection and replacement of other components of the host 1.

[0045] Embodiment 2

[0046] The present embodiment provides an endoscope-assisted water delivery device. In the present embodiment, the detection mechanism 8 includes a magnetic sensor 17 and a magnet 16. The magnetic sensor 17 is built into the shell 14, and the magnet 16 is connected to the pump head 4. When the pump head 4 is connected to the shell 14, the magnetic sensor 17 can monitor the magnetic field of the magnet 16 to achieve the purpose of monitoring the connection status between the pump head 4 and the shell 14.

[0047] Specifically, the magnetic sensor 17 can be arranged in the housing 14, and the magnetic sensor 17 uses the Hall effect to detect whether the pump head 4 is correctly installed. The Hall effect refers to that when a current passes through a conductor, if a magnetic field is applied on both sides of the conductor, a potential difference will be generated on both sides of the conductor perpendicular to the current direction and the magnetic field direction. In the magnetic sensor 17, this potential difference is proportional to the strength of the magnetic field. The pump head 4 is equipped with a magnet 16. When the pump head 4 is correctly installed, the magnet 16 is close to the magnetic sensor 17, and the magnetic sensor 17 detects the magnetic field and generates an electrical signal, indicating that the pump head 4 has been installed in place. On the contrary, if the pump head 4 falls off, the magnet 16 is away from the sensor, the magnetic field disappears, and the magnetic sensor 17 no longer generates an electrical signal, so that it can be judged that the pump head 4 has fallen off. This magnetic sensor 17 based on the Hall effect provides a non-contact detection method that can accurately and quickly detect the installation status of the pump head 4. By monitoring the output signal of the magnetic sensor 17, the device can automatically determine whether the pump head 4 has fallen off, and take corresponding measures, such as stopping the operation or issuing an alarm, to ensure the safety and normal operation of the device. In practical applications, the magnetic sensor 17 can be connected to the control module 11 for communication to transmit a magnetic field monitoring signal.

[0048] The other structures of the endoscope auxiliary water supply device of this embodiment are the same as those of the first embodiment and will not be described again here.

[0049] Embodiment 3

[0050] This embodiment provides an endoscope-assisted water delivery device. In this embodiment, the detection mechanism 8 includes a distance measuring sensor 18, which is connected to the shell 14. The distance measuring sensor 18 can monitor the distance between the shell 14 and the pump head 4 to achieve the purpose of monitoring the connection between the pump head 4 and the shell 14.

[0051] The distance sensor 18 installed on the housing 14 can determine whether the pump head 4 has fallen off by measuring the distance between the pump head 4 and the distance sensor 18. The working principle of this sensor is usually based on the principle of optics or electromagnetic waves. The optical distance sensor 18 determines the distance between the target object and the sensor by sending a light pulse and measuring the time it takes for it to reflect back; the electromagnetic wave distance sensor 18 calculates the distance according to the propagation speed and time of the electromagnetic wave in the medium by emitting electromagnetic waves and receiving the reflected signal. When the pump head 4 is correctly installed, the distance sensor 18 will detect a specific distance value; if the pump head 4 falls off, this distance value will change, thereby triggering the sensor's alarm or control signal to indicate the change in the state of the pump head 4. This non-contact detection method can not only improve safety, but also reduce wear or damage that may be caused by physical contact. The distance sensor 18 can be connected to the control module 11 in communication to transmit the measured distance information to the control module 11.

[0052] The other structures of the endoscope auxiliary water supply device of this embodiment are the same as those of the first embodiment and will not be described again here.

[0053] The endoscope-assisted water delivery device of the present invention delivers flushing liquid into the body, lumen, body cavity or body cavity to flush tissue to remove blood, excrement and other organic matter, thereby improving visibility during endoscopic diagnosis and treatment; the intensity and speed of the water flow can be adjusted according to surgical needs to ensure the stability of water flow and pressure during the operation; at the same time, a detection mechanism 8 is added to monitor whether the pump head 4 falls off to ensure the accuracy of the flushing liquid output flow and improve the safety factor of equipment operation. In addition, the endoscope-assisted water delivery device of the present invention adopts a humanized design, is simple and convenient to operate, and is equipped with an intuitive control panel and display screen, so that the operator can easily grasp and adjust the working status of the device; and has output timing protection to avoid waste or safety protection when forgetting to turn off the output.

[0054] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
