[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "central", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.

[0033] The purpose of this embodiment is to provide an intravenous infusion alarm device, which includes a central ring 1, an alarm device 5 and a casing ring 6. Anti - detachment rings 11 are fixedly installed at both ends of the central ring 1, and a central torsion spring I 13 is provided on the opposite side of the opening of the central ring 1, and the central torsion spring I 13 is located between the side plates 12, and the side plates 12 are installed on one side of the central ring 1.

[0034] In the above invention, the central ring 1 is opened by the first central torsion spring 13 and clamped outside the infusion rod, facilitating the clamping and fixing of infusion rods of different thicknesses by the central ring 1. The anti - detachment ring 11 can reinforce the position of the central ring 1 to prevent the central ring 1 from falling off, and at the same time fix the position of the alarm device 5 on one side, etc.

[0035] Specifically referring to Figure 5 As shown, the clamping ring 55 is installed inside the ring hole 33, and the ring hole 33 is opened at the center of the fixing plate 32. The fixing plate 32 is fixedly connected to the support rod 3 on one side, and the support rod 3 is connected between the fixing plate 32, the connecting plate 54 and the alarm device 5; a rod sleeve 31 is fixedly installed at one end of the support rod 3, and the rod sleeve 31 is inserted inside the sleeve rod ring 4, and the sleeve rod ring 4 is fixedly installed on the outside of the central ring 1.

[0036] In the above invention, the support rod 3 is fixedly connected to the central ring 1 through the sleeve rod ring 4 to connect the alarm devices 5, and the support rod 3 has a certain length, which can separate the infusion tubes on one side of the alarm device 5 to prevent the infusion tubes from being concentrated and entangled together, which is neither convenient for medical staff to search for the infusion tubes nor conducive to the normal delivery of drugs inside the infusion tubes.

[0037] Specifically referring to Figure 3 and Figure 4 As shown, the alarm devices 5 are distributed on the side of the central ring 1, and a buzzer 51 for sound - emitting prompt is fixedly installed on one side of the alarm device 5. And a connecting plate 54 is fixedly connected to one side of the alarm device 5. A clamping ring 55 is inserted inside the connecting plate 54, and an infrared detector 53 is provided on one side of the opening of the alarm device 5.

[0038] Specifically referring to Figure 3 and Figure 4 As shown, there are two groups of flashing lights 52 below the buzzer 51, and the flashing lights 52 are fixedly installed on one side of the alarm device 5. And an anti - slip ring is arranged inside the opening of the alarm device 5. A pressing plate 56 is installed on one side of the mid - point of the alarm device 5, and a second central torsion spring 57 is elastically connected between the pressing plates 56. The two ends of the second central torsion spring 57 are in contact with one side of the pressing plate 56; the alarm device 5 is connected through the pressing plate 56 and the second central torsion spring 57, and the fixing plate 32 is located inside the connecting plate 54.

[0039] In the above invention, the alarm device 5 is arranged to press towards the midpoint through the pressing plate 56 and the central torsion spring II 57, causing the sides to open, thereby clamping the infusion tube. An anti-slip ring is provided at the opening of the alarm device 5 to prevent the alarm device 5 from sliding down on one side of the infusion tube. Moreover, the alarm device 5 detects the liquid inside the infusion tube through the infrared detector 53. When the liquid medicine in the infusion tube is in a state of running out, the infrared detection technology triggers the buzzer 51 to sound, enabling both the patient and medical staff to know that the liquid medicine inside the infusion tube is about to run out, facilitating the medical staff to replace the infusion bottle in a timely manner.

[0040] Specific reference Figure 6 As shown, a circular jack 58 is opened at the bottom of the alarm device 5, and the inner wall of the jack 58 is threaded. A connecting rod 7 is rotatably connected inside the jack 58, and one side of the bottom of the connecting rod 7 is rotatably connected to a support plate 8. Both ends of the connecting rod 7 are threaded, and the support plate 8 is fixedly connected to the sleeve ring 6 on one side.

[0041] In the above invention, the sleeve ring 6 is connected to the alarm device 5 through the support plate 8 and the connecting rod 7, which can fix the position of the sleeve ring 6, facilitating the direct installation of the sleeve ring 6 on one side of the infusion tube.

[0042] Specific reference Figure 8 and Figure 9 As shown, the sleeve ring 6 is located below the alarm device 5, and a rotating toothed ring 66 is rotatably connected below the sleeve ring 6. Moreover, two gear two 6602 are annularly installed on both sides of the rotating toothed ring 66, and the gear two 6602 are meshed and connected to one side of the planetary gear 6604. One side of the planetary gear 6604 is meshed and connected to a rack plate 6605. A connecting column 6606 is fixedly connected at equal intervals above the rack plate 6605, and the connecting column 6606 is fixedly connected to the top clamping tube device 6601.

[0043] In the present invention, one end of the clamping tube device 6601 is arc-shaped, and the clamping tube device 6601 horizontally moves through the connecting column 6606 and the rack plate 6605. Moreover, the side of the clamping tube device 6601 is located at the inner edge of the rotating toothed ring 66. A gear ring 6603 is provided in the mid-lower part of the sleeve ring 6, and both the gear ring 6603 and one side of the rotating toothed ring 66 are provided with notches, and the gear ring 6603 is located below the gear two 6602; the toothed ring 63 is located on one side of the rotating toothed ring 66, and two gear one 64 are provided on both sides of the toothed ring 63, and the gear one 64 are located on one side of the gear two 6602; a ring groove 68 is annularly opened at the bottom of the sleeve ring 6, and the insertion plate 65 is located inside the ring groove 68.

[0044] In the above invention, the rotating gear ring 66 is located outside the infusion tube, and a tube clamp 6601 is also provided outside the infusion tube. The tube clamp 6601 reciprocates through a rack plate 6605, causing the tube clamp 6601 to move back and forth. When the tube clamp 6601 approaches the midpoint, since one end of the tube clamp 6601 is arc-shaped, it can clamp the outside of the infusion tube, reducing the diameter of the infusion tube, thereby reducing the liquid flow rate inside the infusion tube and extending the time for medical staff to change the dressing.

[0045] For specific reference Figure 7 and Figure 9 As shown, a clamping plate 61 is slidably connected to one side of the sleeve ring 6, and strip plates 62 are installed on both sides of the clamping plate 61. The strip plates 62 are located inside side grooves 67 opened on both sides of the sleeve ring 6. A plug plate 65 is rotatably connected below the clamping plate 61, and the plug plate 65 is fixedly connected to a gear ring 63 at the bottom.

[0046] In the above invention, the clamping plate 61 is located inside the sleeve ring 6 through the strip plates 62 to close the opening of the sleeve ring 6, and the gear ring 63 also closes the opening of the rotating gear ring 66, making the device connection complete. Moreover, a gear one 64 inside the gear ring 63 is located on one side of a gear two 6602. When the gear two 6602 rotates, the complete gear facilitates the meshing and rotation of the planetary gear 6604, causing the tube clamp 6601 to move back and forth to clamp the infusion tube.

[0047] In summary, the working principle of the present invention is as follows: The central ring 1 presses the central torsion spring one 13 through the clamping plate 2, causing one side of the central ring 1 to open to clamp and fix infusion rods of different thicknesses. The anti-drop ring 11 increases the friction between the infusion rod and the central ring 1, which can prevent the displacement of the central ring 1. The central ring 1 is fixedly connected to a support rod 3 through a sleeve ring 4. The alarm device 5 is fixed at a fixing plate 32 on one side of the support rod 3 through the clamping ring 55 inserted into an inner ring hole 33 of the fixing plate 32. The alarm device 5 is supported at one end through the support rod 3, so that it is fixed at a specified horizontal position. The infusion tubes are placed at specified positions, and the situation of the infusion tubes being disordered and entangled can be prevented. Then, the alarm device 5 opens one side through a pressing plate 56 and a central torsion spring two 57 to clamp an infusion tube on one side. The alarm device 5 monitors the liquid inside the infusion tube in real time through an infrared detector 53. When the inside of the infusion tube is hollow, the buzzer 51 is triggered to respond, prompting the patient and medical staff with the message that the bottle is about to be empty, allowing the medical staff to pull out the needle or change the liquid medicine as soon as possible and reducing the possibility of blood backflow;

[0048] The sleeve ring 6 is connected to the alarm device 5 through the connecting rod 7, so that the sleeve ring 6 is fixedly located below the alarm device 5. The sleeve ring 6 and the rotating toothed ring 66 are installed outside the infusion tube through an opening on one side. After the sleeve ring 6 is installed on the infusion tube, the clamping plate 61 is slidably installed between the sleeve rings 6. The plate strip 62 and the side groove 67 are used to close the sleeve ring 6, and at the same time drive the toothed ring 63 to close one side of the rotating toothed ring 66. When the medicine in the infusion tube is about to run out, the patient can manually and gently rotate the rotating toothed ring 66. The rotating toothed ring 66 rotates inside the ring groove 68 through the insertion plate 65, and at the same time drives the meshing rotation between the second gear 6602 and the planetary gear 6604 inside the rotating toothed ring 66. When the second gear 6602 rotates, it causes the rack plate 6605 on one side of the planetary gear 6604 to move back and forth. The tube clamp 6601 above the rack plate 6605 can approach the midpoint of the rotating toothed ring 66. One side of the tube clamp 6601 is arc-shaped. When the tube clamps 6601 are closed, a circle is formed in the middle, which can clamp the outside of the infusion tube and reduce the diameter of the infusion tube. Since the internal diameter of the infusion tube is small, the flow rate of the medicine inside can be reduced, so that the medicine flows down slowly, extending the time for medical staff to change the dressing. At the same time, it can also reduce the speed of blood backflow in the later stage of the patient, preventing the danger caused by too fast blood backflow.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
