[0027] In order to better understand the purpose, function and specific design of the present invention, the surgical contrast agent monitoring device of the present invention is further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, the surgical contrast agent monitoring device of the present invention includes a shell component 1 and a monitoring component 2. The shell component 1 includes a shell 101, an opening is provided above the shell 101, and a top cover 102 is connected to the position of the opening above the shell 101. A sealing plate 103 is provided inside the shell 101, and the sealing plate 103 divides the interior of the shell 101 into a counting chamber and a measuring chamber distributed up and down; the monitoring component 2 includes a connected display unit, a counting unit and a measuring unit, the display unit is provided on the top cover 102, the counting unit is provided in the counting chamber, and the measuring unit is provided in the measuring chamber. The two sides of the measuring chamber are respectively connected to the water inlet pipe 104 and the water outlet pipe 105. The contrast agent can enter the measuring chamber through the water inlet pipe 104 and flow out into the body through the water outlet pipe 105. The flow of contrast agent in the measuring chamber can drive the measuring unit to rotate, thereby driving the counting unit to count, and displaying the amount of contrast agent in real time through the display unit.

[0029] Specifically, if Figure 2-4As shown, the measuring unit includes an annular impeller disk 201 and an impeller body 202. The impeller disk 201 is fixed in the measuring chamber, the bottom of the impeller disk 201 is sealed and connected to the bottom of the shell 101, and the outer wall of the impeller disk 201 is interference fit with the inner wall of the measuring chamber. A liquid inlet groove is provided on the side of the impeller disk 201 close to the water inlet pipe 104, and a liquid outlet is provided on the side of the impeller disk 201 close to the water outlet pipe 105; the impeller body 202 includes an impeller shaft 209, one end of the impeller shaft 209 is connected to the bottom of the shell 101 and can rotate relative to the shell, and the other end of the impeller shaft 209 is connected to the counting unit; a plurality of blades are evenly distributed on the impeller shaft 209, and the side of the blade away from the impeller shaft 209 conflicts with the inner cavity of the impeller disk 201, and the side of the blade away from the impeller shaft 209 can slide on the inner cavity surface of the impeller disk 201. The contrast agent enters the inner cavity of the impeller disk 201 through the liquid inlet groove and drives the impeller body 202 to rotate. When the contrast agent reaches the liquid outlet, it flows out through the outlet pipe 105 and enters the body. The counting unit counts the amount of contrast agent used for each rotation of the impeller body 202 and transmits it to the display unit to display the amount of contrast agent used.

[0030] In another embodiment, the bottom of the impeller disc 201 is sealed, the impeller shaft 209 is fixed to the bottom of the impeller disc 201, a bearing is fixed to the bottom of the disc 201, and the impeller shaft 209 is connected to the bearing to reduce the resistance of the impeller body 202 during rotation, and at the same time, reduce the processing difficulty of the shell 101.

[0031] Preferably, the axis of the liquid inlet groove is tilted so that the contrast agent pushes the impeller body 202 to rotate in only one direction. In this embodiment, there are multiple liquid inlet grooves, which are distributed vertically and crosswise on the side of the impeller disk 201 near the water inlet pipe 104, so that the contrast agent can push the impeller body 202 to rotate at different positions.

[0032] The counting unit includes a metering wheel 203, which is connected to the measuring unit. In this embodiment, the metering wheel 203 is connected to the impeller shaft 209 of the impeller body 202. A light shield 205 is provided on the metering wheel 203, which drives the light shield 205 to rotate. A photoelectric sensor 204 is provided in the counting chamber, which monitors the position of the light shield 205. Each time the photoelectric sensor 204 detects the light shield 205, it indicates that the impeller body 202 has rotated one revolution. The photoelectric sensor 204 transmits a monitoring signal to the display unit, which displays the amount of contrast agent used. For example, each rotation of the impeller body 202 indicates that one milliliter of contrast agent is delivered. In this embodiment, the light shield 205 is fixed to the surface of the metering wheel 203, and the photoelectric sensor 204 is fixed to one side of the mounting chamber. The metering wheel 203 is located on top of the sealing plate 103.

[0033] Preferably, the output end of the photosensor 204 of this embodiment is connected to the processing unit, which is connected to the display unit. The display unit includes a display 206, which is fixedly mounted on the upper surface of the top cover 102. The processing unit is fixedly mounted on the lower surface of the top cover 102 and includes a counting module 208, a data storage module 211, and a processor 207. The output end of the photosensor 204 is connected to the input end of the counting module 208, which is connected to the input end of the processor 207. The output end of the processor 207 is connected to the input ends of the display 206 and the data storage module 211, respectively. The counting module 208 sends the measured data to the processor 207, which calculates the amount of contrast agent used based on the number of rotations. The processor 207 sends the calculated data to the display 206 and the data storage module 211, respectively. The display 206 can display the amount used in real time, thereby facilitating observation by medical staff. The data storage module 211 can store the data, thereby facilitating the filling of surgical records after the operation.

[0034] It is worth noting that in this embodiment, a solenoid valve 210 is provided on the water inlet pipe 104 and the water outlet pipe 105, and the output end of the processor 207 is connected to the solenoid valve 210. When the amount of contrast agent used reaches a preset value, the processor 207 closes the solenoid valve 210, thereby stopping the injection of the contrast agent, avoiding excessive use of contrast agent, and effectively reducing medical costs.

[0035] Preferably, the water inlet pipe 104 and the connecting pipe 106 are detachably connected, and the connection method can be a snap-on or threaded connection. The connecting pipe 106 is used to connect the contrast agent infusion pump, and the water outlet pipe 105 is used to connect the syringe. The infusion pump guides the contrast agent through the connecting pipe 106 and the water inlet pipe 104 to the measuring chamber for measurement, and the water outlet pipe 105 is used to guide the contrast agent to the syringe, and the contrast agent is injected through the syringe.

[0036] The model of the processor 207 of the present invention can be ESP32. The processor 207 can calculate and process the monitored data, so as to obtain the usage of the contrast agent, and display it in real time through the display 206, so as to facilitate medical staff to observe during the operation. The model of the photoelectric sensor 204 can be EX-10. Of course, it is understandable that a position sensor or a speed sensor can be added to monitor the rotation data of the impeller body 202. The model of the counting module 208 can be SIMATICS7-300. The data storage module 211 can also be stored on the cloud platform. The data storage module 211 can archive the usage of the contrast agent each time for subsequent reference.

[0037] During use, the injection volume of the contrast agent can be set according to the patient's physical condition. First, it is connected to the contrast agent infusion pump through the connecting tube 106, and the water outlet pipe 105 is connected to the syringe. Then the processor 207 controls the two solenoid valves 210 to open. The two solenoid valves 210 respectively control the flow of the contrast agent in the water inlet pipe 104 and the water outlet pipe 105. The contrast agent is drained to the measuring chamber through the connecting tube 106 and the water inlet pipe 104. The contrast agent enters the inner cavity of the impeller disk 201 and pushes the impeller body 202 to rotate. When the impeller body 202 rotates, the metering wheel 203 is driven to rotate through the impeller shaft 209. When the metering wheel 203 rotates, it drives the light shielding plate 205 to rotate. The diameter of the metering wheel 203 is the same as that of the impeller body 202. The photoelectric sensor 204 can monitor the position of the light shielding plate 205. Each time the sensor 204 detects the light shielding plate 205, it indicates that the impeller body 202 rotates one circle. The photoelectric sensor 204 sends the monitoring signal to the counting module 208, and the counting module 208 counts the number of rotations of the impeller body 202. The impeller body 202 of this embodiment can deliver one milliliter of contrast agent for each rotation. The counting module 208 sends the measured data to the processor 207, and the processor 207 can calculate the amount of contrast agent used according to the number of rotations. When the amount of contrast agent used reaches a preset value, the processor 207 closes the two solenoid valves 210, thereby stopping the injection of the contrast agent, thereby avoiding excessive use of contrast agent, and further reducing medical costs. By real-time monitoring of the contrast agent usage, possible problems can be discovered and dealt with in a timely manner, thereby reducing the occurrence of complications.

[0038] The structural design of the surgical contrast agent monitoring device of the present invention is ingenious. By arranging a water inlet pipe and a water outlet pipe, it can divert the contrast agent, so that the contrast agent can accurately enter the measuring chamber for measurement and be discharged through the water outlet pipe, thereby diverting the contrast agent. In addition, by arranging the impeller disc, impeller body, metering wheel, photoelectric sensor, light shielding plate, impeller shaft and data storage module, the flow rate of contrast agent usage can be monitored. The contrast agent enters the inner cavity of the impeller disc through the obliquely arranged liquid inlet groove, pushing the impeller body to rotate. When the impeller body rotates, the metering wheel is driven to rotate through the impeller shaft. The photoelectric sensor, light shielding plate and counting module can cooperate to count the number of rotations of the metering wheel, thereby monitoring the flow rate of contrast agent usage. By arranging the processor, data storage module and display, the monitoring data can be displayed and stored, which is convenient for medical staff to observe and record. By monitoring the amount of contrast agent used during surgery, medical staff can better control the progress of the operation, reduce unnecessary operations and time waste, and effectively improve the efficiency of the operation.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
