[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] This invention provides an infusion alarm device for thoracic surgery nursing, such as... Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, it includes an alarm body 1, and an adjustment structure is provided on one side of the alarm body 1;

[0028] The adjustment structure includes an electric push rod 2, a striking plate 3, a telescopic plate 4, a moving block 5, and a limiting structure. A clamping groove 6 is provided on one side of the alarm body 1, and an installation groove is provided on one side of the clamping groove 6. An electric push rod 2 is fixedly installed inside the installation groove. A striking plate 3 is fixedly installed on one side of the electric push rod 2. The electric push rod 2 is electrically connected to the alarm body 1. The alarm body 1 has first grooves on both the upper and lower sides of the clamping groove 6. Two telescopic plates 4 are provided inside the first grooves. A moving block 5 is fixedly installed on one end of each of the two telescopic plates 4. A limiting structure is provided on one side of the moving block 5.

[0029] The alarm body 1 is clamped onto the infusion tube, positioning it inside the clamping groove 6. Moving blocks 5 are then moved vertically to the upper and lower sides of the alarm body 1, causing the telescopic plate 4 to extend. This restricts the infusion tube, fixing the position of the moving blocks 5 and thus limiting the infusion tube on both sides of the alarm body 1. This ensures the infusion tube remains vertical, preventing slight bending or twisting that could lead to abnormal dripping and false alarms. Furthermore, if liquid adheres to the wall of the infusion tube inside the clamping groove 6, it could cause further damage. If the drip rate is abnormal, the alarm body 1 will sound an alarm. At the same time, the electric push rod 2 will activate and push the tapping plate 3 to move back and forth to tap the infusion tube. After the drip rate inside the infusion tube returns to normal, the alarm body 1 will stop sounding an alarm. The electric push rod 2 will drive the tapping plate 3 to move into the mounting slot, so that the alarm body 1 on the infusion tube can continue to monitor without the need for manual adjustment or tapping of the infusion tube. When medical staff are not around the patient, the infusion tube can be quickly adjusted, reducing the workload of medical staff. It can also prevent the alarm body 1 from constantly sounding false alarms and increasing the power consumption of the alarm body 1.

[0030] like Figure 2 , Figure 5 , Figure 6 As shown, the alarm body 1 has a button on the top, the electric push rod 2 is located at both ends of the striking plate 3, there are two striking plates 3, the striking plates 3 are connected by a connecting block 7, and the striking plates 3 are provided with clamping structures on both sides and at the upper and lower ends of the clamping groove 6.

[0031] Pressing the button activates the alarm body 1 to monitor the infusion tube. The clamping structure secures the infusion tube, improving its stability. The electric push rod 2 connects to the tapping plate 3, allowing both tapping plates 3 to move simultaneously and gently tap one side of the infusion tube inside the clamping groove 6. This prevents the liquid inside the infusion tube from adhering to the wall for an extended period, affecting the drip rate and causing false alarms, thus increasing the workload of medical staff. When the tapping plate 3 maintains the drip rate inside the infusion tube at a normal level, the alarm body 1 stops alarming, reducing power consumption and extending its service life.

[0032] like Figures 5 to 8 As shown, an installation block 8 is fixedly installed in the middle of the first groove. One side of each of the two telescopic plates 4 is fixedly installed with the installation block 8. The movable block 5 is located on the upper and lower sides of the alarm body 1. Two sliding grooves are opened on the side of the movable block 5 near the limiting structure. The telescopic plates 4, the installation block 8 and the movable block 5 are all symmetrically arranged with respect to the center of the alarm body 1.

[0033] The mounting block 8 facilitates the installation of two telescopic plates 4 inside the first groove. Pulling the two moving blocks 5 simultaneously moves the telescopic plates 4, thereby causing the limiting structure to move to the ends of the infusion tubes on the upper and lower sides of the alarm body 1, limiting the infusion tubes and ensuring that the infusion tubes on the upper and lower sides of the alarm body 1 remain vertical. This prevents slight bending or twisting of the infusion tubes, which could lead to abnormal drip rate and prevent false alarms from the alarm body 1, thus affecting the efficiency of the infusion.

[0034] like Figures 7 to 8 As shown, the limiting structure includes a slider 9, a limiting block 10, a telescopic rod 11, and a first magnetic block 12. The limiting block 10 is fixedly installed on one side of the slider 9, and its other side is slidably connected to the slide groove. Movable grooves are opened on both sides of the limiting block 10. The telescopic rod 11 is fixedly installed inside the movable groove. The first magnetic block 12 is fixedly installed on one side of the telescopic rod 11. An arc-shaped groove is opened on the side of the limiting block 10 that is close to it. The movable groove is located on the left and right sides of the arc-shaped groove. The first magnetic block 12 is located on one side of the limiting block 10. The slider 9, the limiting block 10, the telescopic rod 11, and the first magnetic block 12 are symmetrically arranged around the center of the alarm body 1. The first magnetic blocks 12 are magnetically connected to each other.

[0035] After the moving block 5 moves to the outside of the infusion tube on the upper and lower sides of the alarm body 1, the moving limiting block 10 drives the slider 9 to move along the slide groove, so that the arc groove of the limiting block 10 fits against the outer wall of the infusion tube. At the same time, the first magnetic blocks 12 approach each other and are attracted by magnetism, so that the telescopic rod 11 in the moving groove extends, thereby limiting the two sides of the infusion tube, further improving the stability of the limiting block 10 in limiting the infusion tube, making it easier to keep the infusion tube vertical, and improving the stability of the alarm body 1 in clamping and monitoring.

[0036] like Figures 3 to 5 As shown, the clamping structure includes a clamping block 13, a connecting rod 14, a compression spring 15, a first rack 16, a gear 17, a rotating rod, a second rack 18, a connecting plate 19, a telescopic block 20, and a second magnetic block 21. A connecting rod 14 is fixedly installed on one side of the clamping block 13, a compression spring 15 is fixedly installed on one side of the connecting rod 14, a first rack 16 is fixedly installed on one side of the connecting rod 14 and between the compression springs 15, a gear 17 meshes on one side of the first rack 16, a rotating rod is fixedly installed in the middle of the gear 17, a second rack 18 meshes on one side of the gear 17, a connecting plate 19 is fixedly installed on one side of the second rack 18, a telescopic block 20 is fixedly installed on one side of the connecting plate 19, and a second magnetic block 21 is fixedly installed on one side of the telescopic block 20.

[0037] When the alarm body 1 is clamped onto the infusion tube, the infusion tube is located inside the clamping groove 6. The outside of the infusion tube presses against the clamping block 13, causing the clamping block 13 to drive the connecting rod 14 to move into the second groove, compressing the compression spring 15. The movement of the clamping block 13 can limit the infusion tube according to different sizes, which can improve the applicability of the alarm body 1. At the same time, the connecting rod 14 drives the first rack 16 to move upward, driving the gear 17 and the rotating rod to rotate. The second rack 18 drives the connecting plate 19 and the telescopic block 20 to move downward. Through the action of the second magnetic block 21, the telescopic block 20 extends, causing the second magnetic block 21 to attract and limit the two ends of the infusion tube inside the clamping groove 6, so that the striking plate 3 remains stable when striking the infusion tube, thereby improving the clamping stability of the alarm body 1.

[0038] like Figures 3 to 6 As shown, a second groove is provided between the clamping groove 6 and the first groove. Movable openings are provided on both the upper and lower sides of the clamping groove 6. The clamping block 13 and the connecting rod 14 are located at both ends inside the clamping groove 6. One end of the compression spring 15 passes through the movable opening and is fixedly installed on the inner wall of the top of the second groove. The first rack 16 extends through the movable opening into the interior of the second groove. Both ends of the rotating rod are rotatably connected to the inner wall of the second groove. A movable plate is fixedly installed on one side of the second rack 18. The movable plate and the connecting plate 19 are slidably connected to the inner wall of the second groove.

[0039] When the clamping block 13 moves the connecting rod 14 upward, the connecting rod 14 causes the compression spring 15 to move from the movable opening into the second groove, compressing the compression spring 15 and connecting it to the inner wall of the second groove. This improves the stability of the movement of the clamping block 13 and the connecting rod 14. When the connecting rod 14 moves the first rack 16 upward into the second groove, the gear 17 drives the rotating rod to rotate along the inner wall of the second groove. This causes the second rack 18 to move the moving plate and the connecting plate 19 downward along the inner wall of the second groove, thereby improving the stability of the movement of the second rack 18 and the telescopic block 20. This facilitates the downward movement of the telescopic block 20 into the clamping groove 6, and the second magnetic block 21 limits the two ends of the infusion tube, improving stability.

[0040] like Figures 3 to 6 As shown, movable openings are provided on both sides of the movable opening and on the upper and lower sides of the clamping groove 6. Both sides of the telescopic block 20 are slidably connected to the inner wall of the second groove, and one end of it extends through the movable opening to both sides of the clamping block 13. The clamping block 13, the telescopic block 20 and the second magnetic block 21 are symmetrically arranged around the center of the clamping groove 6. The side of the clamping block 13 that is close to each other is arc-shaped. The second magnetic blocks 21 are magnetically connected to each other. The clamping block 13, the telescopic block 20 and the second magnetic block 21 are all located on both sides of the striking plate 3.

[0041] By symmetrically arranging the clamping block 13, the telescopic block 20, and the second magnetic block 21, the arc-shaped side of the clamping block 13 can be tightly attached to both sides of the infusion tube. When the connecting plate 19 moves downward, it drives the telescopic block 20 from the moving port to the inside of the clamping groove 6, and the telescopic block 20 is extended by the action of the second magnetic block 21, which limits both sides of the infusion tube. Since the clamping block 13, the telescopic block 20, and the second magnetic block 21 are all located on both sides of the striking plate 3, it is convenient that after the telescopic block 20 and the clamping block 13 limit both ends of the infusion tube, it will not hinder the movement of the striking plate 3, and the striking plate 3 will remain stable when striking the infusion tube.

[0042] like Figures 1 to 3 As shown, a baffle 22 is provided between the clamping grooves 6. A slot is provided on the inner wall of the bottom of the clamping groove 6. The bottom of the baffle 22 is inserted into the slot. A strip-shaped opening is provided on the top of the baffle 22 and located at the top of the alarm body 1. The baffle 22 is movably connected to the inner wall of the strip-shaped opening. A fixing rod 23 is fixedly installed on the top of the baffle 22. A movable block 24 is fixedly installed through the strip-shaped opening of the fixing rod 23. The movable block 24 is located between the strip-shaped opening and the top of the alarm body 1.

[0043] The stability of the alarm body 1 is further improved by the baffle 22 on one side of the clamping groove 6. By moving the movable block 24 upward, the movable block 24 drives the fixed rod 23 and the baffle 22 to move upward, so that one end of the baffle 22 moves away from the slot and moves into the inside of the strip opening, exposing the clamping groove 6. This makes it easier to remove the alarm body 1 from the infusion tube. After removal, the movable block 24 is moved downward so that the fixed rod 23 drives the baffle 22 to move back to its original position, shielding and protecting the clamping groove 6 to prevent dust and impurities from entering the clamping groove 6 and affecting monitoring, which would make it difficult to sound an alarm.

[0044] Working principle: In use, pulling the movable block 24 moves the fixed rod 23 and the baffle 22, causing one end of the baffle 22 to separate from the slot and expose the clamping groove 6. Then, the alarm body 1 is clamped onto the infusion tube, so that the infusion tube is located inside the clamping groove 6. Moving the movable block 24 downward causes the fixed rod 23 to move the baffle 22 back to its original position. Then, moving the movable blocks 5 to the upper and lower sides of the alarm body 1 causes the telescopic plate 4 to extend. The moving limiting block 10 causes the slider 9 to move along the slide groove, so that the arc-shaped groove of the limiting block 10 fits against the outer wall of the infusion tube. At the same time, the first magnetic blocks 12 approach each other and are attracted by magnetism, causing the telescopic rod 11 in the moving groove to extend, thereby limiting the infusion tube on the upper and lower sides of the alarm body 1, so that the infusion tube always remains vertical. To prevent slight bending or twisting of the infusion tubing, which could cause abnormal drip rate and trigger a false alarm, the alarm body 1 is activated when the infusion tubing inside the clamping groove 6 is clinging to the wall and medical staff are not present, causing an abnormal drip rate. Simultaneously, the electric push rod 2 moves the tapping plate 3 back and forth to tap the infusion tubing until the drip rate returns to normal. Once normal, the alarm body 1 stops alarming. The electric push rod 2 then moves the tapping plate 3 into the mounting groove, allowing the infusion tubing to continue monitoring the alarm body 1. This eliminates the need for manual adjustment and tapping of the infusion tubing, enabling quick adjustments and reducing the workload of medical staff. Furthermore, it prevents continuous false alarms and reduces the power consumption of the alarm body 1.

[0045] When the alarm body 1 is clamped onto the infusion tube, the infusion tube is located inside the clamping groove 6. The outside of the infusion tube presses against the clamping block 13, bringing the clamping block 13 close to the outside of the infusion tube. This causes the clamping block 13 to move the connecting rod 14 into the second groove, compressing the compression spring 15. The movement of the clamping block 13 can be used to limit the size of infusion tubes of different sizes, thus improving the applicability of the alarm body 1. At the same time, the connecting rod 14 drives the first rack 16 into the second groove, and drives the gear 17 and the rotating rod along... As the second rack 18 rotates along the inner wall of the second groove, the connecting plate 19, the moving plate, and the telescopic block 20 move downwards along the inner wall of the second groove, causing the telescopic block 20 to move from the moving port into the clamping groove 6. Through the action of the second magnetic block 21, the telescopic block 20 extends, causing the second magnetic block 21 to attract and limit the two ends of the infusion tube inside the clamping groove 6, so that the striking plate 3 remains stable when striking the infusion tube, further improving the stability of the alarm body 1 clamping, and making the alarm body 1 clamped stably for use.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
