[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] This invention provides, for example Figure 1-7The suspended automatic intravenous infusion hanger shown includes a telescopic rod 1, a hook 2, a fixed shaft 4, a bag hanging assembly 3, and a bag changing assembly 5. The hook 2 is installed at the top of the telescopic rod 1, the fixed shaft 4 is installed at the bottom of the telescopic rod 1, the bag hanging assembly 3 is located outside the fixed shaft 4, and the bag hanging assembly 3 is used to suspend and clamp the infusion bags. The bag changing assembly 5 is located at the bottom of the fixed shaft 4. The telescopic rod 1 can be hooked at a designated position through the hook 2, and the telescopic rod 1 can extend and retract to change the working height of the fixed shaft 4, the bag hanging assembly 3, and the bag changing assembly 5. The bag changing assembly 5 is linked with the bag hanging assembly 3. The bag changing assembly 5 is used to drive the infusion stopper puncture device to puncture and connect with the infusion bags on the bag hanging assembly 3. The bag hanging assembly 3 can store multiple infusion bags, and the bag changing assembly 5 can clamp and drive the infusion stopper puncture device to move and dock with the infusion bags on the bag hanging assembly 3.

[0049] Furthermore, the bag-hanging assembly 3 includes a mounting housing 31, a metering display 32, an infusion bag hook 33, a mounting sleeve 35, a reset assembly 38, a mounting collar 36, and a bag clamp 37. The mounting housing 31 is rotatably sleeved on the outside of the fixed shaft 4. The metering display 32 is mounted on the outer wall of the mounting housing 31. The infusion bag hook 33 is connected to the bottom of the metering display 32, and the infusion bag is hung on the infusion bag hook 33. The metering display 32 can detect the weight of the liquid inside the infusion bag through the infusion bag hook 33. Thus, when the liquid inside the infusion bag is exhausted, the bag-changing assembly 5 can drive the infusion plug puncture device to connect to the unused infusion bag. The mounting sleeve 35 is installed at the bottom of the mounting housing 31. The mounting sleeve 35 is set outside the fixed shaft 4 through the reset assembly 38. The mounting collar 36 is fixedly sleeved on the bottom of the outer wall of the mounting sleeve 35. The liquid bag clamp 37 is installed outside the mounting collar 36. The liquid bag clamp 37 corresponds to the infusion bag hook 33. The liquid bag clamp 37 can clamp the infusion plug at the bottom of the infusion bag, which facilitates the subsequent bag changing assembly 5 to drive the infusion plug puncture device to dock with it. After the infusion plug puncture device docks with the infusion plug at the bottom of the infusion bag, the liquid bag clamp 37 releases the infusion plug at the bottom of the conveyor belt, thereby ensuring the accuracy of the metering display 32 in detecting the liquid inside the infusion bag.

[0050] In particular, the reset assembly 38 includes a cover 381, a first fixing block 382, ​​a second fixing block 383, an arc rod 384, and a reset spring 385. The cover 381 is mounted on the top of the mounting sleeve 35 and is rotatably sleeved on the outer wall of the fixed shaft 4. The second fixing block 383 is fixedly connected to the top of the bearing sleeve 51. The end of the arc rod 384 is fixedly connected to the second fixing block 383. The reset spring 385 is slidably sleeved on the outer wall of the arc rod 384. The first fixing block 382 is fixedly connected to the bottom of the cover 381. The bottom of the first fixing block 382 has a slot. The first fixing block 382 is sleeved on the outer wall of the arc rod 384 through the slot, and the first fixing block 382 is located on one side of the reset spring 385. Figure 6 As shown in the top view, when the bag changing assembly 5 operates, it drives the mounting sleeve 35 to rotate. That is, when the mounting sleeve 35 rotates counterclockwise relative to the bearing sleeve 51, the first fixing block 382 rotates and presses the reset spring 385. When the bag changing assembly 5 operates without driving the mounting sleeve 35 to rotate, under the action of the reset spring 385, the first fixing block 382 drives the mounting sleeve 35 to rotate clockwise.

[0051] Specifically, a fixing sleeve 34 is fixedly connected to the top of the cover 381. The top of the fixing sleeve 34 is fixedly connected to the mounting housing 31. Under the action of the fixing sleeve 34 and the cover 381, the mounting sleeve 35 and the mounting housing 31 are in a relatively fixed state, thereby keeping the metering display 32 and the liquid bag clamp 37 in a relative state. The fixing sleeve 34 is rotatably sleeved on the outer wall of the fixing shaft 4. The outer wall of the fixing shaft 4 is sleeved with a limit bearing 312. The limit bearing 312 is located between the cover 381 and the bearing sleeve 51. The top of the mounting housing 31 has a through hole that matches the fixing shaft 4. A damping sleeve 39 is fixedly sleeved in the inner cavity of the through hole. The top of the mounting housing 31 is provided with Mounting cap 310 is connected to the output end of telescopic rod 1. Mounting cap 310 is sleeved on the top of the outer wall of fixed shaft 4. A fixing bolt 311 is provided on one side of mounting cap 310. A threaded groove is opened on the top of the outer wall of fixed shaft 4. One end of the outer wall of fixing bolt 311 is threaded into the inner cavity of the threaded groove. Under the action of mounting cap 310 and limit bearing 312, mounting housing 31, fixing sleeve 34 and mounting sleeve 35 can be stably rotated and installed on the outside of fixed shaft 4. When fixing bolt 311 is removed, fixed shaft 4 is separated from mounting cap 310, and fixed shaft 4 can slide and separate from mounting housing 31, fixing sleeve 34 and mounting sleeve 35.

[0052] Specifically, the bag changing assembly 5 includes a support sleeve 51, a mounting plate 52, a needle clamp 53, a servo motor 54, a transmission assembly 55, a guide assembly 56, and a docking rod 57. The support sleeve 51 is fixedly connected to the bottom of the fixed shaft 4. The mounting plate 52 is located at the bottom of the support sleeve 51, and the needle clamp 53 is installed at the end of the mounting plate 52. The needle clamp 53 can clamp the infusion plug puncture device. Both the needle clamp 53 and the liquid bag clamp 37 are composed of a drive electric motor and two corresponding clamping blocks. The two clamping blocks on the liquid bag clamp 37 match the infusion plug at the bottom of the infusion bag, so that the relative movement of the two clamping blocks on the liquid bag clamp 37 is possible. The needle clamp 53, which holds the infusion bag's bottom stopper, has two clamping blocks that match the infusion stopper puncture device. The relative movement of these two clamping blocks allows the needle clamp 53 to hold the infusion stopper puncture device. A servo motor 54 is mounted on the top of the inner cavity of the supporting sleeve 51. The servo motor 54 is connected to the mounting plate 52 via a transmission assembly 55. Viewed from above, the servo motor 54 can drive the mounting plate 52 and the needle clamp 53 to rotate counterclockwise via the transmission assembly 55. A guide assembly 56 is mounted on the bottom of the inner cavity of the supporting sleeve 51 and works in conjunction with the mounting plate 52. A connecting rod 57 is fixedly connected to the mounting plate 52. At the top, when the mounting plate 52 rotates, the guide assembly 56 can push the mounting plate 52 down, thereby causing the needle clamp 53 to separate the infusion plug puncture device from the infusion bag. The docking rod 57 cooperates with the guide assembly 56 to guide and limit the mounting plate 52. The bottom of the mounting collar 36 has a docking groove 58 that matches the docking rod 57. The bottom of the inner wall of the docking groove 58 has a rounded chamfer. The docking groove 58 at the bottom of the mounting collar 36 corresponds to the liquid bag clamp 37 on the outer wall of the mounting collar 36. The docking rod 57 docks with the docking groove 58, so that the needle clamp 53 corresponds to the liquid bag clamp 37. When the mounting plate 52 rotates relative to the fixed axis 4 When in motion, the mounting plate 52 can drive the mounting collar 36 to rotate synchronously via the docking rod 57. Thus, under the action of the guide assembly 56, the mounting plate 52 drives the needle clamp 53 and the infusion stopper to descend, causing the infusion stopper to separate from the infusion bag. This causes the infusion bag on the bag hanging assembly 3 to move synchronously with the mounting plate 52, the needle clamp 53, and the infusion stopper. When the needle clamp 53 drives the infusion stopper to separate from the infusion bag, and the mounting plate 52 descends, it causes the docking rod 57 to separate from the docking groove 58 on the mounting collar 36. At this time, under the action of the reset assembly 38, the bag hanging assembly 3 resets and rotates outside the fixed shaft 4.

[0053] Furthermore, the transmission assembly 55 includes a transmission sleeve 551, a transmission shaft 552, a connecting collar 555, a support collar 554, and a support spring 556. The output end of the servo motor 54 is connected to the transmission sleeve 551. The outer wall of the transmission shaft 552 is vertically slidably sleeved with the transmission sleeve 551. The bottom of the transmission shaft 552 is fixedly connected to the mounting plate 52. The connecting collar 555 is installed on the top of the outer wall of the transmission shaft 552 and slidably sleeved with the transmission sleeve 551. Externally, a support collar 554 is slidably sleeved inside the bearing sleeve 51. The support collar 554 is located at the bottom of the connecting collar 555, and the support spring 556 is located at the bottom of the support collar 554. A sliding hole 557 is provided on the outer wall of the transmission sleeve 551. A slider 558 is slidably sleeved in the inner cavity of the sliding hole 557. The slider 558 is fixedly connected between the connecting collar 555 and the transmission shaft 552. Under the action of the slider 558, the transmission shaft 552 can rotate synchronously with the transmission sleeve 551. When the drive shaft 552 slides vertically relative to the drive sleeve 551, the mounting plate 52 can drive the needle clamp 53 to move up and down, realizing the needle insertion and removal action. A plane bearing 559 is sleeved on the outer wall of the drive sleeve 551. The plane bearing 559 is located between the connecting collar 555 and the support collar 554. A fixing collar 553 is fixedly sleeved in the inner cavity of the bearing sleeve 51. A guide rod 5510 is fixedly connected to the bottom of the fixing collar 553. The bottom of the guide rod 5510 passes through the support sleeve. Ring 554 is fixedly connected to limit block 5511. The outer wall of guide rod 5510 is slidably sleeved with support spring 556. Support spring 556 is located between limit block 5511 and support ring 554, and support spring 556 is linked with guide assembly 56. Support spring 556 can give connecting ring 555 an upward elastic force through support ring 554 and plane bearing 559, so that drive shaft 552 drives mounting plate 52 and needle clamp 53 to have an upward force.

[0054] Furthermore, the guide assembly 56 includes a positioning collar 561, guide blocks 562, connecting blocks 563, and locking blocks 564. The positioning collar 561 is sleeved on the bottom of the inner cavity of the bearing sleeve 51. The guide blocks 562 are fixedly connected to the bottom of the positioning collar 561 in a ring array, and the number of guide blocks 562 corresponds to the number of liquid bag clamps 37 on the outside of the mounting collar 36. Figure 4As shown, when the mounting plate 52 drives the needle clamp 53 to rotate counterclockwise, the mounting plate 52 can slide downward along the inclined surface of the guide block 562, thereby causing the mounting plate 52 to drive the needle clamp 53 and the infusion plug puncture device to move downward. When the mounting plate 52 moves to the bottom of the guide block 562, the connecting rod 57 separates from the connecting groove 58 at the bottom of the mounting collar 36. At this time, the mounting collar 36, mounting housing 31, fixing sleeve 34, and mounting sleeve 35 rotate and reset. The mounting plate 52 continues to rotate under the action of the servo motor 54 and the transmission assembly 55. The mounting plate 52 separates from the guide block 562, and the connecting rod 57 connects with the connecting groove 58 at the bottom of the mounting collar 36. At this time, the infusion plug puncture device held by the needle clamp 53 at the end of the mounting plate 52 is aligned with the liquid bag clamp 37. Corresponding to the infusion bag, under the action of the support spring 556, the connecting collar 555 drives the mounting plate 52 to rise through the drive shaft 552, so that the mounting plate 52 drives the needle clamp 53 and the infusion stopper to puncture and connect with the infusion bag. When the connecting rod 57 is not aligned with the connecting groove 58 at the bottom of the mounting collar 36, the top of the connecting rod 57 is in contact with the mounting collar 36, preventing the mounting plate 52 from rising. This avoids the situation where the mounting plate 52, through the needle clamp 53, drives the infusion stopper to rise but cannot align with the infusion bag. The upward force of the support spring 556 acting on the needle clamp 53 through the connecting collar 555, drive shaft 552, and mounting plate 52 is sufficient to allow the needle clamp 53 to drive the infusion stopper to insert into the infusion bag. The connecting block 563 is fixedly connected to the positioning sleeve. At the top of ring 561, a locking block 564 is fixedly connected to the inner wall of the bearing sleeve 51. A connecting block 563 is engaged with the outside of the locking block 564. The positioning ring 561 is rotatably sleeved on the outside of the drive shaft 552. A guide block 562 is used to guide the mounting plate 52. A slot is provided on one side of the connecting block 563. The outer wall of the locking block 564 is slidably engaged with the inner cavity of the slot. A connecting plate 565 is provided at the top of the connecting block 563. A positioning rod 567 is fixedly connected to the bottom of the connecting plate 565. A positioning hole matching the positioning rod 567 is provided at the top of the connecting block 563. A positioning groove matching the positioning rod 567 is provided at the top of the locking block 564. An installation hole 566 is provided on the outer wall of the bearing sleeve 51. One side of the outer wall of the connecting plate 565 slides against the installation hole 566. The connecting plate 565 is connected to an arc-shaped component 568 at one end, and a limiting plate 569 is connected to the other end of the arc-shaped component 568. The limiting plate 569 is slidably sleeved on the outer wall of the guide rod 5510. The limiting plate 569 is located between the support spring 556 and the limiting block 5511. The support spring 556 can also exert a compressive force on the limiting plate 569, ensuring the stability of the engagement between the connecting plate 565 and the positioning rod 567 with the connecting block 563 and the locking block 564. This ensures the stability of the positioning collar 561 installation. Furthermore, the multiple connecting blocks 563 on the top of the positioning collar 561 are arranged in a circular array. This allows the connecting plate 565 to rise and move, causing the positioning rod 567 to separate from the connecting block 563, and the positioning collar 561 to rotate.This allows the positioning collar 561 to drive the connecting block 563 to slide and separate from the locking block 564.
