The monitoring sensor controls the operation of the micro motor through the controller. A worm is provided at the output end of the micro motor. The micro motor drives the worm to rotate so that the sliding block on the worm slides along the direction of the worm. The sliding block drives the pressure wheel to squeeze the outer wall of the infusion tube to adjust the flow rate inside the infusion tube. The limit plate arranged on the right side of the positioning groove limits the squeezing of the infusion tube. The controller and the micro motor are each provided with two. When the monitoring sensor detects that the flow rate inside the infusion tube is too fast, the two controllers synchronously control the operation of the two micro motors. The positioning groove is a semicircular structure, and two rotating limit plates are provided on the right side of the positioning groove. The two limit plates are connected in abutment with each other when not subject to external force. The infusion tube can be inserted into the positioning groove for positioning and placement by squeezing the two limit plates inward.

[0004] As a further improvement of the present invention, a lifting handle is provided on the top of the adjuster, and a traction hook plate is provided in the middle of the back of the adjuster. Two traction hook plates are provided and are installed symmetrically on the left and right to abut against the surface of the support column.

An inclined notch is provided between the first touch plate and the second touch plate to match the pointed end of the insulating plate.

[0009] The beneficial effects of the present invention are: 1. When the monitoring sensor detects that the flow rate inside the infusion tube is too fast, the two controllers synchronously control the two micromotors to rotate forward, so that the worms on the two micromotors synchronously drive the sliding blocks to slide and drive the two pressing wheels to squeeze the outer walls of the front and rear sides of the infusion tube respectively to change the inner diameter space of the infusion tube. On the contrary, when the flow rate inside the infusion tube is detected to be too slow, the micromotors reverse, so that the pressing wheels loosen the infusion tube. At this time, the inner diameter of the infusion tube gradually recovers, which speeds up the flow rate of the liquid medicine, and realizes adaptive adjustment of the flow rate of the liquid medicine inside the infusion tube, thereby improving the infusion effect of the patient; 2. During the infusion process, as the medicine in the medicine bag gradually decreases, the suspension rod gradually and steadily moves upward and resets under the telescopic reset of the telescopic hose and the support of the support arm. When the delivery of the medicine in the medicine bag is about to end, the first touch plate on the suspension rod moves up and contacts the second touch plate at the lower end of the alarm, so that the alarm is powered on and sounds an alarm, which can promptly remind the patient and medical staff to change the medicine bag or stop the infusion, avoiding the dangerous situation of blood backflow in the patient.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings: Example

[0019] As attached Figure 1 To Attachment Figure 5 As shown: The present invention discloses a liquid medicine hanger for hospital pharmacy, which comprises a movable base 1, a regulator 2, a support column 3, an adjustment column 4 and a hanging rod 5. The middle part of the movable base 1 is connected to the lower end of the support column 3, and the regulator 2 is supported by the support column 3. The lower end of the adjustment column 4 slides inside the support column 3 to adjust the height of the hanging rod 5 at the upper end of the adjustment column 4. The display screen 22 installed on the front end surface of the regulator 2 is electrically connected to the monitoring sensor 25 inside the positioning groove 26 set on the right side of the regulator 2. The monitoring sensor 25 monitors the flow rate of the infusion tube G plugged and installed in the positioning groove 26. The regulator 2 is also installed with a controller 251 and a micro motor 252. The monitoring sensor 25 controls the micro motor through the controller 251. The micro motor 252 controls the operation. A worm 253 is provided at the output end of the micro motor 252. The micro motor 252 drives the worm 253 to rotate so that the sliding block 254 on the worm 253 slides along the direction of the worm 253. The sliding block 254 drives the pressing wheel 255 to squeeze the outer wall of the infusion tube G to adjust the internal flow rate of the infusion tube G. The limiting plate 27 set on the right side of the positioning groove 26 squeezes and limits the infusion tube G. The top of the regulator 2 is also provided with a lifting handle 21, and the middle part of the back of the regulator 2 is provided with a traction hook plate 24. The traction hook plate 24 is provided with two and is symmetrically installed on the surface of the support column 3. The bottom of the regulator 2 is installed with a base 23, and the rear end of the base 23 is provided with a rotating buckle plate 231. The end of the rotating buckle plate 231 is provided with a positioning shaft 2 32 is positioned and rotated at the rear end of the base 23, and a locking plate 234 is provided between the two rotating buckle plates 231. The two locking plates 234 are fixed to the fixed height of the support column 3 by bolt locking, and a pulley 233 is also provided inside the rotating buckle plate 231 to slide inside the groove of the support column 3, so that the base 23 can be rotated and adjusted at the fixed height position of the support column 3. In the present invention, when the patient is infused, the hanging rod 5 is moved by moving the base 1, and the angle of the regulator 2 is adjusted. When adjusting the angle, the regulator 2 is driven to rotate by rotating the base 23, so that the medicine bag is hung on the hanging rod 5 and the infusion tube G can be stuck in the positioning groove 26. Then, during the infusion process, the patient can monitor the patient's position. The sensor 25 monitors the flow rate of the medicine liquid inside the infusion tube G, and the monitoring data is displayed on the display screen 22. When the monitoring sensor 25 detects that the flow rate inside the infusion tube G is too fast, the two controllers 251 synchronously control the two micro motors 252 to rotate forward, so that the worm 253 on the two micro motors 252 synchronously drives the sliding block 254 to slide and drive the two pressure wheels 255 to squeeze the outer walls on the front and rear sides of the infusion tube G respectively to change the inner diameter space of the infusion tube G. On the contrary, when it is detected that the flow rate inside the infusion tube G is too slow, the micro motor 252 reverses, so that the pressure wheel 255 loosens the infusion tube G. At this time, the inner diameter of the infusion tube G gradually recovers, which speeds up the flow rate of the medicine liquid, thereby realizing adaptive adjustment of the flow rate of the medicine liquid inside the infusion tube G, thereby improving the infusion effect of the patient.

[0020] A preferred technical solution, the controller 251 and the micro motor 252 are each provided with two. When the monitoring sensor 25 detects that the flow velocity inside the infusion tube G is too fast, the two controllers 251 synchronously control the two micro motors 252 to operate, so that the worm 253 on the two micro motors 252 synchronously drives the sliding block 254 to slide and drive the two pressing wheels 255 to squeeze the outer walls of the front and rear sides of the infusion tube G respectively to change the inner diameter space of the infusion tube G. On the contrary, the pressing wheel 255 loosens the infusion tube G, so that the inner diameter of the infusion tube G is restored, thereby realizing adaptive adjustment of the flow velocity of the liquid medicine inside the infusion tube G; A preferred technical solution, the positioning groove 26 is in a semicircular structure, and two rotating limit plates 27 are provided on the right side of the positioning groove 26. The two limit plates 27 are connected to each other when not subjected to external force. By squeezing the two limit plates 27 inward, the infusion tube G can be inserted into the positioning groove 26 for positioning and placement, thereby preventing the infusion tube G from being separated from the positioning groove 26 during the process of squeezing the infusion tube G to adjust the flow rate, thereby improving the stability of the flow rate adjustment of the infusion tube G; A preferred technical solution is that the two traction hook plates 24 have an arc-shaped contact end with the surface of the support column 3 and match the surface of the support column 3. When the angle of the adjuster 2 is rotated and adjusted by pulling the handle 21, the two traction hook plates 24 rotate in a circle in contact with the surface of the support column 3, thereby improving the stability of the rotation of the adjuster 2. Embodiment 2: Based on embodiment 1, as shown in the attached Figure 6 To Attachment Figure 7 As shown: The outer end of the hanging rod 5 is in a hook shape to hang the medicine bag, and a spring rod 52 is provided at the lower end of the hanging rod 5, and an adjusting slider 51 is slidably installed on the spring rod 52. The upper end of a support arm 53 provided on the hanging rod 5 is axially connected to the lower end of the adjusting slider 51, and the lower end of the support arm 53 is axially connected to the lower end surface of a connecting pipe 54 installed on the top of the adjusting column 4. A battery 541 is installed inside the lower end of the connecting pipe 54, and a telescopic hose 542 is provided inside the upper end of the connecting pipe 54. The top of the telescopic hose 542 is connected to the connecting pipe 54. The lifting guide plate 5431 on the conductive mechanism 543 disposed at the upper end is elastically supported, and the lifting guide plate 5431 is connected to the inner end of the suspension rod 5 to provide elastic support for the inner end of the suspension rod 5. The negative electrode of the battery 541 is electrically connected to the second touch plate 5442 at the lower end of the alarm 544 at the top of the connecting tube 54 through a wire, and the positive electrode of the battery 541 is electrically connected to the first touch plate 5432 installed on the top of the lifting guide plate 5431 at the upper end of the connecting tube 54 through a wire. The lower end of the alarm 544 is also provided with a compression spring 5441 and the second touch plate 5442. 442 is elastically connected, an insulating plate 5433 is provided between the first touch plate 5432 and the second touch plate 5442, and the insulating plate 5433 is pulled between the first touch plate 5432 and the second touch plate 5442 by the pull plate 4331 connected to the outside, and the hanging rod 5 drives the first touch plate 5432 and the second touch plate 5442 to contact and conduct when the hanging rod 5 moves upward, so that the alarm 544 is powered on and sounds an alarm. In the present invention, when the medicine bag is hung on the hanging rod 5, the medicine bag applies gravity to the hanging rod 5, so that the hanging rod 5 descends. During the infusion process, as the medicine in the medicine bag gradually decreases, the suspension rod 5 gradually and stably moves upward and resets under the telescopic reset of the telescopic hose 542 and the support of the support arm 53. When the delivery of the medicine in the medicine bag is about to end, the first touch plate 5432 on the suspension rod 5 moves upward and contacts the second touch plate 5442 at the lower end of the alarm 544, so that the alarm 544 is powered on and sounds an alarm, which can promptly remind the patient and medical staff to change the medicine bag or stop the infusion, thereby avoiding the dangerous situation of blood backflow to the patient.

[0021] A preferred technical solution, the support arm 53 is supported on the hanging rod 5 and the connecting tube 54 bracket at an angle of 45 degrees. When the hanging rod 5 hangs the medicine bag, the support arm 53 provides support for the hanging rod 5, and the adjusting slider 51 at the upper end of the support arm 53 slides elastically along the spring rod 52 to ensure that the hanging rod 5 as a whole can stably descend in parallel on the connecting tube 54, stably suspend the medicine bag, and avoid the hanging rod 5 being tilted and causing the medicine bag to fall when the medicine bag is hung on the outer end of the hanging rod 5 and the hanging rod 5 descends. During the continuous infusion process, the internal liquid medicine components of the medicine bag hung on the outer side of the hanging rod 5 are reduced, and the hanging rod 5 stably moves upward and resets under the telescopic reset of the telescopic hose 542 and the support of the support arm 53; A preferred technical solution is that an inclined notch is provided between the first touch panel 5432 and the second touch panel 5442 to match the pointed end of the insulating plate 5433. When not in use, the insulating plate 5433 can be smoothly inserted between the first touch panel 5432 and the second touch panel 5442, so that the insulation between the first touch panel 5432 and the second touch panel 5442 cannot be conducted to avoid accidental touch and alarm. Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
