Description

Technical Field

[0001] The present invention relates to the technical field of post-interventional monitoring, and in particular to an intelligent monitoring device for post-interventional bleeding. Background Art

[0002] Minimally invasive interventional therapy is a minimally invasive technique that is performed under image guidance and places instruments or drugs into diseased tissue with minimal trauma (no skin incision, only puncture) to perform physical, mechanical or chemical treatments. It has the advantages of small wounds, low costs and quick recovery.

[0003] When the surgical site involves a cavity where fluid accumulates, or there is a lot of exudate at the surgical site, a drainage tube needs to be placed at the incision after the operation to help drain the fluid and prevent postoperative infection. After minimally invasive surgery, the patient also needs to be closely monitored for signs of continued bleeding and unacceptable bleeding volume and bleeding rate, depending on the situation. Studies have shown that massive bleeding can lead to blood loss and shock. In addition to the amount of bleeding, the bleeding rate is also critical to its severity. If heavy bleeding is not treated in time within a short period of time, it may endanger the patient's life. Therefore, when a patient has bleeding complications after surgery, vital signs should be measured every 15-30 minutes, the drainage tube should be squeezed once every 30 minutes, the drainage fluid should be poured out, and the amount, color, and properties of the drainage fluid should be recorded. This is crucial to improving the surgical cure rate and whether postoperative heavy bleeding can be rescued in time. Therefore, the inventor invented a bleeding monitoring device that is compatible with a drainage tube, which has higher monitoring accuracy. Summary of the invention

At this time, the slider 10 is located at the end away from the drainage tube 1, and the two light shielding plates 13 are not put together. The medical staff sets the relevant parameters through the control screen 4; when blood-red material flows through the drainage tube 1, the color sensor 14 detects the color signal and sends the signal to the control module 6. The control module 6 controls the telescopic motor 2 48 to turn on. At this time, the end of the threaded rod 50 away from the telescopic motor 2 48 is located in the perforation 1 46, and the telescopic motor 2 48 controls the threaded rod 50 to move in the direction away from the telescopic motor 2 48. Since the threaded rod 50 is threadedly connected with the gear three 43, when the threaded rod 50 moves downward, the gear three 43 rotates, thereby driving the gear two 42 to rotate, the gear two 42 drives the annular plate 16 to rotate, and the annular plate 16 drives the gear one 18 to rotate. At this time, the gear one 18 drives the winding rod 19 to rotate, and the pull rope one 23 is wound on the winding rod 19. The pull rope one 23 pulls the slider one 10 to move toward the direction close to the drainage tube 1. In this process, the rotation of the annular plate 16 will move the position where the pull rope two 24 is connected to the annular plate 16 toward the direction close to the slideway two 9. Therefore, the length of the pull rope two 24 located in the slideway two 9 will become longer, so the pull rope one 23 can pull the slider one 10 to move toward the direction close to the drainage tube 1;

[0051] The slider 10 moves toward the drainage tube 1 with the squeezing block 12 on the vertical rod. When the vertical rod 34 moves to the slideway 8 directly opposite to the extension cavity 27, the two squeezing blocks 12 just press the drainage tube 1 tightly. The two semi-annular light shielding plates 13 just fit together to form a ring to block the light outside the monitoring area. A funnel-shaped space is formed at the squeezed drainage tube 1. At this time, if the wound continues to bleed, the funnel-shaped space will quickly turn red. The color sensor 14 sends a red signal to the control module 6. The control module 6 analyzes the red signal. If the degree of red does not reach the degree of immediate alarm, the telescopic motor 2 48 will control the threaded rod 50 to move upward, and the pull rope 24 will pull the slider 10 away from the drainage tube 1. The control module 6 controls the extrusion block 12 to squeeze the drainage tube 1 again, and continues to observe the color of the liquid in the drainage tube 1. If the color of the liquid is the same as the color observed last time, or the color becomes darker, the control module 6 controls the alarm module 5 to sound an alarm to remind the medical staff that there may be continuous bleeding, so that the medical staff can take measures quickly. The number of times the extrusion block 12 is released and squeezed can be set. If more caution is required, it can be set to more than three times. If there is no blood red in the funnel-shaped space after the extrusion block 12 squeezes the drainage tube 1, or there is no blood red after the extrusion block 12 is released once or twice, it indicates that there is no bleeding.

[0052] In order to prevent the sediment in the drainage fluid from adhering to the drainage tube 1 of the monitoring section, the control module 6 controls the telescopic motor 2 48 to drive the gear 4 44 to rotate at regular intervals. It should be noted that when the top of the vertical rod 34 is located opposite to the extension cavity 27, the top of the threaded rod 50 just passes through the perforation 1 46, and the bottom of the threaded rod 50 is just located at the edge of the top of the perforation 2 47, and the insertion rod 29 is just inserted into the insertion hole 28. At this time, the telescopic motor 2 48 drives the threaded rod 50 to continue to move downward, and the threaded rod 50 will drive the gear 4 44 to rotate, and the gear 3 43 is stationary, so the slider 10 will not move, and the gear 4 44 drives the gear 5 45 to rotate, and the gear 5 45 drives the follower rod 58 to move, thereby driving the slider 3 30 in the slideway 4 31 Movement; the telescopic motor 2 48 drives the threaded rod 50 to move up and down in the perforation 2 47, thereby driving the slider 3 30 to move back and forth along the thickness direction of the vertical rod, thereby driving the vertical rod to move back and forth, and then driving the two extrusion blocks 12 to move back and forth. It should be noted here that the two extrusion blocks 12 move in opposite directions each time, so the two extrusion blocks 12 will knead the drainage tube 1, loosen the sediment attached to the drainage tube 1, and make the sediment flow into the drainage bag with the drainage fluid; the telescopic motor 1 35 can drive the extrusion block 12 to move up and down, so the sediment on the drainage tube 1 of the monitoring section can be cleaned by adjusting the height of the extrusion block 12, and try to ensure that the sediment on the drainage tube 1 of the monitoring section does not affect the monitoring line of sight of the color sensor 14, thereby improving the monitoring effect and practicality;

[0053] In order to prevent the drainage tube 1 from being blocked, the squeezing block 12 may be controlled to squeeze the drainage tube 1 once every certain period of time, so that the drainage tube 1 remains unobstructed.
