Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a cardiovascular flushing and drainage device with an alarm function. Background Technology
[0002] Existing methods require doctors or nurses to replace or drain the drainage tank when the blood volume reaches a predetermined level. This process is cumbersome. In contrast, the "Cardiovascular Clinical Drainage Device" disclosed in patent application number "CN202323347516.7" represents a more mature technology. Through a control mechanism, when one drainage tank is nearly full, another begins collecting blood. At this point, a valve is opened to clear the blood. This process is comfortable for the patient and does not affect the effectiveness of the drainage device. Furthermore, a ruler and timer are used to... The device is designed to calculate blood flow and velocity, but it has the following drawbacks: blockage can only be assessed manually, and medical staff cannot be notified promptly when blockage occurs. It cannot monitor the flow rate and volume of drainage fluid in real time, nor can it detect the collection of drainage fluid. When the drainage fluid is full, manual observation is required to check if the drainage volume is full. It cannot automatically notify staff to replace the collection bucket when the fluid accumulation is full. Furthermore, its functionality is limited during collection; it lacks a flushing function, making it inconvenient for doctors to flush the affected area. During flushing, it is difficult to control the direction and flow rate of the flushing water. Utility Model Content

In the process of collecting fluid, the device has limited functions and lacks flushing function, making it inconvenient for doctors to flush the affected area, and it is difficult to control the direction and flow rate of the flushing water during the flushing process.
[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a storage box, a microcontroller processor on one side of the storage box, a first high-precision pressure sensor at the bottom of one side of the inner wall of the storage box, a drainage fluid storage tank at the top of the first high-precision pressure sensor, a high-precision peristaltic pump embedded on one side of the top of the storage box, a micro-flow sensor at the top of one side of the high-precision peristaltic pump, and a drainage tube at the bottom of one side of the high-precision peristaltic pump, one end of which is sealed and connected to the top of the drainage fluid storage tank.
[0005] In an embodiment of the cardiovascular flushing and drainage device with alarm function of this utility model, a second high-precision pressure sensor is provided at the bottom of the other side of the inner wall of the storage box, a flushing fluid storage tank is provided at the top of the second high-precision pressure sensor, a water pump is provided at the top of the storage box, and the water inlet of the water pump is sealed and connected to the top of the flushing fluid storage tank.
[0006] In this solution, during the rinsing process, the remaining liquid content in the rinsing fluid storage tank is detected by a second high-precision pressure sensor. When the rinsing fluid is almost used up, the second high-precision pressure sensor transmits the information to the microcontroller processor and transmits the data through a wireless data transmitter. Doctors and nurses can view the usage data in real time in their offices or wards. At the same time, the alarm voice communicator issues an alarm voice prompt to the doctor to replenish the rinsing fluid, realizing remote monitoring and management.
[0007] In an embodiment of the cardiovascular flushing and drainage device with alarm function of this utility model, the top of the water pump is provided with a delivery hose, one end of the delivery hose is provided with a flow limiting solenoid valve, one end of the flow limiting solenoid valve is provided with a flushing handle, one side of the inner wall of the flushing handle is provided with a sealing tube, a flushing tube is rotatably connected inside the sealing tube, and one end of the flushing tube is threadedly connected with a multi-hole flushing nozzle.
[0008] In this solution, during use, the flushing fluid is drawn from the flushing fluid storage tank by a water pump, flows into the delivery hose and out of the multi-hole flushing nozzle, and the input amount of flushing fluid is controlled by a flow-limiting solenoid valve to adjust the flushing force.
[0009] In one embodiment of the cardiovascular flushing and drainage device with alarm function of this utility model, a toothed disc is provided on one side of the outer wall of the flushing tube, a micro-adjustment motor is embedded on one side of the top of the inner wall of the flushing handle, and a drive gear is provided at the output end of the micro-adjustment motor, which meshes with the toothed disc.
[0010] In this solution, a micro-adjustment motor drives a gear, which in turn rotates a meshing gear disc to adjust the flushing angle of the multi-hole flushing nozzle.
[0011] In an embodiment of the cardiovascular flushing and drainage device with alarm function of this utility model, the bottom side of the flushing handle is provided with a direction adjustment button, a water supply button, and a water flow adjustment button from top to bottom.
[0012] In this solution, the operator controls the rotation direction of the micro-adjusting motor by controlling the direction adjustment button to change the water jet direction, controls the water flow rate and flushing pressure of the flow limiting solenoid valve by controlling the water flow adjustment button, and controls the water supply of the water pump by controlling the water supply button.
[0013] In an embodiment of the cardiovascular flushing and drainage device with alarm function of this utility model, a wireless data transmitter is provided on the top of the microcontroller processor, and an alarm voice communicator is provided on one side of the microcontroller processor.
[0014] In this solution, during use, the drainage tube absorbs the accumulated fluid. At this time, a micro-flow sensor detects the flow rate of the accumulated fluid, and the flow rate data is transmitted to the microcontroller processor and then to the hospital's information management system in the office via a wireless data transmitter for real-time monitoring. A high-precision peristaltic pump extracts the accumulated fluid, which is stored in a drainage fluid storage tank. The high-precision peristaltic pump can adjust its extraction speed. When a blockage occurs, the micro-flow sensor detects the change in flow rate and transmits the data to the microcontroller processor. At this time, an alarm voice communicator sounds an alarm to remind staff of the blockage. A first high-precision pressure sensor detects the weight pressure of the drainage fluid storage tank. When there is too much accumulated fluid, an audible and visual alarm signal is triggered.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1) The accumulated fluid is aspirated through a drainage tube. A micro-flow sensor detects the fluid flow rate, which is transmitted to a microcontroller and then wirelessly to the hospital's information management system in the office for real-time monitoring. A high-precision peristaltic pump extracts the fluid, storing it in a drainage fluid reservoir. The pump's extraction speed is adjustable. When a blockage occurs, the micro-flow sensor detects the change in flow rate and transmits the data to the microcontroller. At this point, an alarm voice communicator sounds, alerting staff to the blockage. The micro-flow sensor detects the outflow... When fluid accumulates, the signal is transmitted to the microcontroller processor, which calculates the amount of fluid discharged from the patient. When the patient discharges too much fluid, the peristaltic pump immediately stops fluid delivery and automatically shuts off the drainage function to prevent excessive fluid discharge. The first high-precision pressure sensor detects the weight pressure of the drainage fluid storage tank. When the first high-precision pressure sensor detects that the collected fluid volume is too high, the signal is processed by the microcontroller processor, and the alarm voice communicator sends out an audible and visual alarm signal to promptly notify staff to clean up the collected fluid. This system enables unmanned, real-time, and accurate monitoring of the drainage fluid volume, improving the safety of equipment use. 2) The rotation direction of the micro-adjusting motor is controlled by the control direction adjustment button. The micro-adjusting motor drives the gear, which in turn rotates the meshing gear plate, adjusting the flushing angle of the multi-hole flushing nozzle. The water flow rate and flushing pressure of the flow limiting solenoid valve are controlled by the water flow adjustment button. The water supply of the water pump is controlled by the water supply button. Attached Figure Description
