[0016] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] Example like Figures 1-7 As shown, an infusion monitoring and alarm device is provided, including a support base 1, a support vertical plate 2 is fixedly connected to the upper surface of the support base 1, an mounting plate 3 is provided on the upper surface of the support vertical plate 2, a support rod 4 is fixedly connected to the upper surface of the mounting plate 3 by multiple bolts, and an adjustment mechanism 5 is provided at the top of the support rod 4. The adjustment mechanism 5 includes a fixed circular box 501, the inner wall of which is fixedly connected to the outer wall of the support rod 4. An adjustment circular plate 502 is rotatably connected to the inner wall of the fixed circular box 501 via a rotating shaft. Multiple through-holes 503 are provided on the upper surface of the adjustment circular plate 502. A through-hole 504 is provided in front of the lower inner surface of the fixed circular box 501. An ultrasonic liquid level sensor 505 is provided in front of the inner surface of the fixed circular box 501 and behind the through-hole 504. An observation window 523 is embedded in the front surface of the fixed circular box 501. A counterweight 24 is provided on the upper surface of the support base 1 and in front of the support vertical plate 2. In operation, medical staff first place the infusion bottles to be used into the multiple placement slots 503 on the adjusting disc 502 inside the adjusting mechanism 5 in sequence for pre-storage. Then, by rotating the adjusting disc 502, the placement slots 503 can be precisely aligned with the insertion holes 504 on the front of the lower surface inside the fixed disc 501. At this point, medical staff can easily complete the installation of the infusion bottles and subsequent bottle replacement operations. After installation, the infusion tube passes through the insertion hole 504 for infusion. During the infusion process, the ultrasonic level sensor 505 located at the front of the fixed disc 501 and behind the insertion hole 504 continuously monitors the liquid level in the currently used infusion bottle. Medical staff can also directly view the status of the infusion bottle through the observation window 523 embedded in the front surface of the fixed disc 501. At the same time, the counterweight 24 on the upper surface of the support base 1, located in front of the support vertical plate 2, can effectively ensure the overall stability of the device and prevent the device from tipping over and affecting the infusion. When the ultrasonic level sensor 505 detects that the fluid level in the infusion bottle has reached the preset lower limit, the device will promptly trigger an alarm to remind medical staff to handle the situation. The multiple placement slots 503 of the adjustment mechanism 5 enable the orderly pre-storage of infusion bottles, and the design of adjusting the rotation of the circular plate 502 and aligning it with the insertion hole 504 significantly simplifies the bottle-changing operation for medical staff, improves efficiency, and reduces the workload of frequent trips to the ward to check on bottle changes. The real-time monitoring and alarm function of the ultrasonic level sensor 505 can accurately grasp the infusion progress, avoiding risks such as backflow of blood or air entering the blood vessels due to untimely handling after infusion, thus ensuring infusion safety. The observation window 523 facilitates intuitive inspection by medical staff, while the counterweight 24 enhances the stability of the device, ensuring a smooth infusion process. The overall device structure is reasonably designed and easy to operate, effectively improving the efficiency and safety of clinical infusion care and reducing the workload of medical staff.
[0018] like Figure 1 and Figure 3 As shown, an equipment mounting slot 6 is provided below the front surface of the support vertical plate 2. A fixing plate 7 is fixedly connected to the inner rear surface of the equipment mounting slot 6 by multiple bolts. A power module 8 is provided on the left side of the front surface of the fixing plate 7, and a PLC controller 9 is provided on the right side of the front surface of the fixing plate 7. A protective door 10 is fixedly connected to the front surface of the equipment mounting slot 6 by a hinge. The core function of the power module 8 is to provide stable power to all electrical components of the entire device, ensuring the normal operation of all functions of the device. The PLC controller 9, as the control core of the device, is responsible for receiving and processing various sensor signals, and then triggering corresponding control commands. The two work together to ensure the reliable realization of the core functions of the device. The matching design of the equipment mounting slot 6, the fixing plate 7 and the protective door 10 not only realizes the orderly assembly of electrical components, but also improves the safety and stability of component operation and extends the service life of the components.
[0019] like Figure 2 and Figure 3 As shown, a control cavity 11 is provided above the rear surface of the support vertical plate 2. An electric telescopic rod 12 is fixedly connected to the lower surface of the control cavity 11. The top end of the output shaft of the electric telescopic rod 12 is fixedly connected to the center of the lower surface of the mounting plate 3. An inspection cover plate 13 is fixedly connected to the rear of the control cavity 11 by multiple bolts. The height of the mounting plate 3, the upper support rod 4, and the adjustment mechanism 5 can be precisely adjusted by the telescopic movement of the electric telescopic rod 12, adapting to the operating needs of medical staff of different heights and the usage requirements of different infusion scenarios. The inspection cover 13 is fixedly connected to the rear of the control chamber 11 by multiple bolts, which facilitates the later inspection and maintenance of the electric telescopic rod 12 in the chamber, and also protects the electric telescopic rod 12 to prevent external debris from entering and affecting its normal operation.
[0020] like Figures 4-6 As shown, a control box 506 is fixedly connected to the rear surface of the fixed circular box 501. The inner sidewall of the fixed circular box 501 and the interior of the control box 506 are both provided with an arc-shaped groove 507. The outer sidewall of the adjusting circular plate 502 is provided with an annular groove 508. Multiple toothed blocks 509 are fixedly connected inside the annular groove 508. A motor 510 is fixedly connected to the lower interior surface of the control box 506. A transmission rod 511 is fixedly connected to the top of the output shaft of the motor 510. The top of the transmission rod 511 is rotatably connected to the upper interior surface of the control box 506 through a rotating shaft. A toggle gear 512 is fixedly connected to the outer sidewall of the transmission rod 511. The front surface of the toggle gear 512 passes through the arc-shaped groove 507 and meshes with the outer sidewall of the multiple toothed blocks 509. The control box 506, fixedly connected to the rear surface of the fixed circular box 501, provides an installation and protection carrier for the components that drive the rotation of the adjusting circular plate 502. The arc-shaped groove 507, which is opened together on the inner side wall of the fixed circular box 501 and the inside of the control box 506, provides reasonable space for the insertion and movement of the transmission structure. The annular groove 508 opened on the outer side wall of the adjusting circular plate 502 is used to stably assemble multiple toothed blocks 509. The multiple toothed blocks 509 are evenly distributed along the annular groove 508 to form a transmission gear ring structure, providing a power transmission basis for the rotation of the adjusting circular plate 502. The motor 510, fixed on the lower surface inside the control box 506, serves as the power source. The transmission rod 511, fixed at the top of its output shaft, can rotate synchronously under the drive of the motor 510. The top of the transmission rod 511 is rotatably connected to the upper surface inside the control box 506 through a rotating shaft, which can ensure the rotation of the transmission rod 511. The stability of the process is ensured by the actuating gear 512 fixed to the outer wall of the transmission rod 511. Its front surface passes through the arc-shaped groove 507 and meshes with multiple tooth blocks 509 in the annular groove 508, forming a complete transmission mechanism. This mechanism enables the transmission of power from the motor 510 to the adjusting disc 502, thereby automatically controlling the rotation of the adjusting disc 502. This eliminates the need for medical personnel to manually rotate the adjusting disc 502 to achieve precise alignment between the placement slot 503 and the insertion hole 504, significantly reducing the operational intensity for medical personnel. At the same time, the control box 506 provides dust and collision protection for the internal transmission components such as the motor 510 and the transmission rod 511. The reasonable opening of the arc-shaped groove 507 avoids interference between components during the transmission process, ensuring the smooth and stable implementation of the automatic rotation adjustment function and improving the ease of use and automation of the device.
[0021] like Figure 2 As shown, an anti-slip pad 14 is fixedly connected to the front of the lower surface of the support base 1, and rollers 15 are embedded symmetrically arranged on the rear surface of the support base 1. An operating lever 16 is fixedly connected to the rear surface of the support vertical plate 2. The anti-slip pad 14 fixedly connected to the front of the lower surface of the support base 1 increases the friction between the device and the ground when it is placed, effectively preventing the device from sliding during use and ensuring placement stability. The symmetrically embedded rollers 15 on the rear surface of the support base 1 cooperate with the operating rod 16 fixedly connected to the rear surface of the support vertical plate 2. Medical staff only need to push the operating rod 16 to easily move the entire device with the help of the rollers 15, making it convenient to transport to different wards or infusion areas. When the device is moved to the target position, the anti-slip pad 14 can be closely attached to the ground to prevent the device from shifting due to the rolling of the rollers 15, thus balancing the convenience of device movement and placement stability.
[0022] like Figures 4-7As shown, the upper surface of the adjusting circular plate 502, located outside the plurality of placement slots 503, is symmetrically provided with actuating grooves 513. The interior of each of the plurality of placement slots 503 is symmetrically provided with locking slots 514. Each of the plurality of actuating grooves 513 contains an actuating rod 515. The opposite ends of two adjacent actuating rods 515 are fixedly connected to clamping plates 516. The upper surfaces of two adjacent actuating rods 515 are fixedly connected to side plates 517. The two sides of each of the plurality of placement slots 503 are fixedly connected to side plates 518. The opposite sides of two adjacent side plates 518 are fixedly connected to... A guide rod 519 is fixedly connected. The outer walls of the multiple guide rods 519 are slidably connected to the interior of multiple side plates 517. Each outer wall of the multiple guide rods 519 is fitted with a return spring 520. The two ends of the multiple return springs 520 are fixedly connected to the opposite sides of the adjacent side plates 517 and 518. The inner wall of the fixed circular box 501 and the two toggle rods 515 located in front are fixedly connected to the opposite sides of the two toggle rods 515. The opposite sides of the two semicircular extrusion plates 521 are in contact with the opposite sides of the two toggle rods 515 in front. In the infusion monitoring and alarm device, the adjusting circular plate 502 has symmetrically arranged actuating grooves 513 on the outer side of multiple placement slots 503, providing space for the movement of the actuating rods 515. The symmetrically arranged slots 514 inside the multiple placement slots 503 provide a suitable position for the extension and retraction of the clamping plates 516. The actuating rods 515 in each actuating groove 513 are fixed to the clamping plates 516 at their opposite ends, which can clamp and fix the infusion bottle. The side plates 517 are fixed to the upper surface of adjacent actuating rods 515. The second side plate 518, which is symmetrically fixed inside the placement slot 503, cooperates with the outer wall of the guide rod 519 fixed on the opposite side of the second side plate 518, which is slidably connected to the inside of the first side plate 517, thus guiding the movement of the actuating rod 515. The two ends of the return spring 520 sleeved on the outer wall of the guide rod 519 are fixedly connected to the opposite sides of the first side plate 517 and the second side plate 518, respectively, which can drive the actuating rod 515 to reset with the clamping plate 516; when the adjusting circular plate 502 rotates, one of the placement slots 503 moves to When the two levers 515 on the outer side of the placement groove 503 are directly above the insertion hole 504, their opposite sides will contact the opposite sides of the two semi-circular pressing plates 521 fixed to the inner wall of the fixed circular box 501. Under the pressing action of the semi-circular pressing plates 521, the two levers 515 will move in opposite directions along the lever groove 513, and drive the two clamping plates 516 to move synchronously, thereby automatically clamping and fixing the infusion bottle in the placement groove 503 to prevent the infusion bottle from shaking or tipping over during the infusion process, ensuring the safety of the infusion. The fluid is kept stable. When the placement slot 503 rotates away from the position directly below the insertion hole 504 as the adjusting disc 502 rotates, the actuating rod 515 disengages from the compression of the semi-circular compression plate 521. The elastic rebound force of the return spring 520 will drive the actuating rod 515 and the clamping plate 516 to return to their original positions, releasing the clamping of the infusion bottle. This makes it easier for medical staff to pick up and put down the infusion bottle. The entire clamping and releasing process does not require manual operation, realizing the automatic clamping and detachment of the infusion bottle, further improving the automation level and ease of use of the device.
[0023] like Figure 7 As shown, the inner opposite sides of the multiple actuating grooves 513 are fixedly connected to limit slide rods 522, and the outer walls of the multiple limit slide rods 522 are respectively slidably connected to the inner sides of the multiple actuating rods 515. The limiting slide rods 522, which are fixedly connected to the opposite sides inside the multiple actuating grooves 513, have their outer walls slidably connected to the interior of the multiple actuating rods 515, thereby providing precise guidance and limiting constraints for the movement of the actuating rods 515. This effectively prevents the actuating rods 515 from deviating, tilting, or getting stuck during their reciprocating movement along the actuating grooves 513, ensuring that the actuating rods 515 always slide smoothly in the horizontal direction, improving the stability and reliability of clamping the infusion bottle, and further optimizing the operation of the device's automatic clamping function.
[0024] like Figure 1 andFigure 3 As shown, a display screen 17 is provided on the front surface of the supporting vertical plate 2 and above the protective door 10; a control button 18 is provided on the front surface of the supporting vertical plate 2 and below the display screen 17; a call button 19 is provided on the front surface of the supporting vertical plate 2 and below the control button 18; and a speaker 20 is provided on the front surface of the supporting vertical plate 2 and below the call button 19. The display screen 17 can display real-time information such as the current infusion bottle level, infusion progress, and device operating status, allowing medical staff to intuitively understand the infusion situation. The control buttons 18 below the display screen 17 allow for manual adjustment of various device functions, improving the flexibility of device operation. The call button 19 allows patients to trigger a call signal with one click when they need help, promptly notifying medical staff to come to the scene and optimizing the efficiency of doctor-patient communication. The speaker 20 below the call button 19 can emit a clear prompt tone when the fluid level reaches the alarm threshold or when the patient triggers the call signal, reminding medical staff to intervene in time. It can also play the device's operation prompt voice, further improving the ease of use and intelligence of the device, and effectively improving the work efficiency of clinical infusion nursing.
[0025] like Figure 1 , Figure 2 and Figure 5 As shown, a control cavity 21 is provided on the upper part of the support rod 4. An electric telescopic rod 22 is fixedly connected to the lower surface of the control cavity 21. A top cover 23 is provided on the upper surface of the fixed round box 501. The upper surface of the top cover 23 is fixedly connected to the top end of the output shaft of the electric telescopic rod 22. When the device is not in use, the electric telescopic rod 22 retracts, causing the top cover 23 to move downwards and completely cover the top opening of the fixed round box 501. This protects the core components inside the fixed round box 501 from dust and foreign objects, preventing damage to the components due to dust accumulation or collisions with foreign objects, and extending the service life of the components. When the device needs to be used, the electric telescopic rod 22 extends, causing the top cover 23 to move upwards, exposing the top opening of the fixed round box 501. This makes it easy for medical staff to place the infusion bottle into the placement slot 503. The lifting and lowering control of the entire top cover 23 is convenient, effectively balancing protective function and ease of use.
