[0002] Intravenous infusion chairs play a vital role in various aspects of medical settings, allowing patients to receive dressing changes in a comfortable position. The chairs are typically ergonomically designed with comfortable seats and backrests, and adjustable angles allow patients to choose a suitable sitting posture, reducing physical fatigue. Simultaneously, the chair helps stabilize the patient's limbs, preventing tension or involuntary movement during dressing changes that could interfere with the procedure, avoid needle displacement or dislodgement, or cause secondary injury, thus ensuring patient safety and treatment effectiveness. Their flexibility allows for rapid transfer between different wards and treatment areas, saving medical staff time in moving equipment and patients.

[0003] However, existing technologies, such as Chinese Publication No. CN222585192U, "A Dressing Chair for Intravenous Infusion Therapy," disclose a dressing chair for intravenous infusion therapy, relating to the field of dressing chair technology. It includes a first support part, a second support part rotatably mounted on one side of the first support part, and a third support part rotatably mounted on the other side of the first support part. A first support frame is fixedly connected to the bottom of the first support part, and a first shelf is welded to the middle of the first support frame. A set of connecting blocks is slidably connected to the bottom surface of the first shelf, and a trash can is fixedly connected to the bottom surface of the connecting blocks. Armrest pads are provided on the other two opposite sides of the first support part, and a rotating frame is fixedly connected below the armrest pads. A fixed shaft is connected to the internal bearing of the rotating frame, and the fixed shaft is inserted and fixed inside the first support part. This device enables the dressing chair to be used in multiple functions.

[0004] However, this device lacks a backrest and footrest adjustable structure, making it impossible to quickly adjust the dressing chair to a lying position, thus preventing the patient from being in a horizontal position, increasing blood flow to the brain, relieving discomfort, and buying time for further emergency treatment. It also fails to prevent the patient's condition from worsening due to improper positioning at critical moments, and is not convenient for rapid transfer between different wards and treatment areas, wasting the time of medical staff in moving equipment and patients. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where the device does not have a backrest and footrest that can be adjusted synchronously, so that the dressing chair cannot be quickly adjusted to a lying position, so that the patient's body is in a horizontal position, increasing blood supply to the brain, relieving discomfort symptoms, and buying time for further emergency treatment. It also cannot prevent the patient's condition from being aggravated due to improper positioning at critical moments, and it is not convenient to quickly transfer between different wards and treatment areas, wasting the time of medical staff to move equipment and patients.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, please refer to Figures 1 to 6 This utility model provides a technical solution: an intravenous infusion treatment dressing chair, including a fixed plate 1, two shaft plates 2 fixedly connected to both sides of the fixed plate 1, a rotating rod 3 rotatably connected to the inner side of the two shaft plates 2, two connecting blocks 4 fixedly sleeved on the outer surface of the rotating rod 3, an adjusting plate 5 fixedly connected to one side of the two connecting blocks 4, a pushing assembly provided on the outer surface of the rotating rod 3, the pushing assembly including a crank 6, the inside of the crank 6 fixedly sleeved on the outer surface of the rotating rod 3, a synchronizing rod 7 rotatably connected to the end of the two cranks 6 away from the rotating rod 3, a first soft cushion 8 fixedly connected to the top of the fixed plate 1, and a second soft cushion 9 fixedly connected to one side of the adjusting plate 5.

[0027] Multiple support rods 10 are fixedly connected to the bottom of the fixed plate 1. A pressure-bearing shell 11 is fixedly connected to the bottom of the multiple support rods 10. Two hand support rods 28 are fixedly connected to the top of the pressure-bearing shell 11. An infusion support plate 29 is fixedly sleeved on the outer surface of the hand support rods 28. A first shaft block 12 is fixedly connected to one side of the pressure-bearing shell 11. An electric push rod 13 is rotatably connected inside the first shaft block 12. A second shaft block 14 is rotatably connected to the end of the electric push rod 13 away from the first shaft block 12. One side of the second shaft block 14 is fixedly connected to one side of the adjusting plate 5. The electric push rod 13 is fixed to the pressure-bearing shell 1 through the first shaft block 12. On one side, the electric push rod 13 pulls the upper adjusting plate 5 through the second shaft block 14, causing the connecting block 4, the rotating rod 3, and the crank 6 to rotate around the rotating rod 3 as the axis inside the shaft plate 2. Multiple positioning rods 15 are fixedly connected to the inner surface of the pressure shell 11, and anti-detachment plates 16 are fixedly connected to the bottom of the positioning rods 15. Pressure plates 17 are movably sleeved on the outer surfaces of the multiple positioning rods 15. Multiple pressure wheels 18 are rotatably connected inside the pressure plate 17. The pressure wheels 18 inside the pressure plate 17 can move the device after contacting the ground. Tension springs 19 are movably sleeved on the outer surfaces of the positioning rods 15. The top of the pressure plate 17 is fixedly connected to the inner surface of the pressure shell 11. The bottom of multiple tension springs 19 is fixedly connected to the top of the pressure plate 17. Under the tension of the tension springs 19, the pressure plate 17 and the pressure wheel 18 will rise, so that the pressure wheel 18 will no longer contact the ground. The top of the pressure plate 17 is rotatably connected to the force roller 20. The bottom of the force roller 20 is provided with a force-applying inclined block 21. The top of the force-applying inclined block 21 is fixedly connected to the moving plate 22. The force-applying inclined block 21 moves along the axis of the limiting rod 24 and, under the force applied to the force roller 20, causes the pressure plate 17 to descend along the axis of the positioning rod 15. A limiting sleeve 23 is fixedly connected to one side of the movable plate 22. A limiting rod 24 is movably embedded in the inner surface of the limiting sleeve 23. The two ends of the limiting rod 24 are fixedly connected to the inner surface of the pressure shell 11. The limiting sleeve 23 can only move along the axial direction of the limiting rod 24. An internal threaded sleeve 25 is fixedly connected to the side of the movable plate 22 away from the limiting sleeve 23. A threaded rod 26 is threadedly connected to the inner surface of the internal threaded sleeve 25. The outer surface of the threaded rod 26 is rotatably connected to the inside of the pressure shell 11 and extends out one end. A rocker arm 27 is fixedly connected to the extended end of the threaded rod 26. Rotating the thread will drive the internal threaded sleeve 25.

[0028] In this embodiment, the rocker arm 27 drives the threaded rod 26 to rotate inside the pressure shell 11. The rotating thread drives the internal threaded sleeve 25. The limiting sleeve 23 on the other side of the moving plate 22 can only move along the axis of the limiting rod 24. Therefore, the rotating thread drives the force-applying inclined block 21 to move along the axis of the limiting rod 24. Under the force applied to the force roller 20, the pressure plate 17 descends along the axis of the positioning rod 15. The anti-detachment plate 16 can prevent the pressure plate 17 from falling off. After the pressure roller 18 inside the pressure plate 17 contacts the ground, it can move the device and move the device to the target position. Then, the moving plate 22 moves in the opposite direction so that the force-applying inclined block 21 no longer contacts the force roller 20. Under the tension of the tension spring 19, the pressure plate 17 will descend. As the pressure roller 18 rises, it no longer contacts the ground. When the dressing chair is used and needs to be reclined, the electric push rod 13 can be activated. The electric push rod 13 is fixed to one side of the pressure shell 11 via the first shaft block 12. The electric push rod 13 will pull the upper adjustment plate 5 via the second shaft block 14, causing the connecting block 4, the rotating rod 3, and the crank 6 to rotate inside the shaft plate 2 around the rotating rod 3 as the axis. When the crank 6 rotates, it will drive another crank 6 via the synchronizing rod 7 to simultaneously level the lower adjustment plate 5. The coverage area of ​​the first soft cushion 8 and the second soft cushion 9 is slightly larger than the area of ​​the fixed plate 1 and the adjustment plate 5, which can prevent the hinge from affecting the patient's sitting experience. The fixed plate 1 is fixed above the pressure shell 11 via the support rod 10.

[0029] Example 2, as Figures 1 to 6 As shown, the propulsion assembly also includes a U-shaped rod 30. The bottom of the U-shaped rod 30 is fixedly connected to the top of the pressure shell 11. The outer surface of the U-shaped rod 30 is rotatably connected to a first rotating wheel 31. The outer surface of the first rotating wheel 31 is driven by two synchronous belts 32. The inner surface of the synchronous belt 32 away from the first rotating wheel 31 is driven by a second rotating wheel 33. The interior of the second rotating wheel 33 is fixedly sleeved on the outer surface of the rod 3.

[0030] In this embodiment, when the rotating rod 3 rotates, it can also drive the second rotating wheel 33 to rotate, and under the transmission action of the synchronous belt 32, it drives the first rotating wheel 31 to rotate on the outer surface of the U-shaped rod 30. At the same time, another synchronous belt 32 on the outer surface of the first rotating wheel 31 will drive another second rotating wheel 33 to rotate, and the adjusting plate 5 below will also be leveled at the same time.

[0031] Working principle: First, the rocker arm 27 drives the threaded rod 26 to rotate inside the pressure shell 11. The rotating thread drives the internal threaded sleeve 25. The limiting sleeve 23 on the other side of the moving plate 22 can only move along the axis of the limiting rod 24. Therefore, the rotating thread drives the force-applying inclined block 21 to move along the axis of the limiting rod 24. Under the force applied to the force roller 20, the pressure plate 17 descends along the axis of the positioning rod 15. The anti-detachment plate 16 can prevent the pressure plate 17 from falling off. After the pressure roller 18 inside 7 contacts the ground, the device can be moved to the target position. Then, the moving plate 22 moves in the opposite direction, so that the force-applying inclined block 21 no longer contacts the force roller 20. Under the tension of the tension spring 19, the pressure plate 17 and the pressure roller 18 will rise, so that the pressure roller 18 no longer contacts the ground. When the dressing chair is used and needs to be reclined, the electric push rod 13 can be activated. The electric push rod 13 is fixed to one side of the pressure shell 11 through the first shaft block 12. The lever 13 pulls the upper adjusting plate 5 through the second shaft block 14, causing the connecting block 4, the rotating rod 3, and the crank 6 to rotate inside the shaft plate 2 around the rotating rod 3 as the axis. When the crank 6 rotates, it drives another crank 6 through the synchronous rod 7, which simultaneously levels the lower adjusting plate 5. The coverage area of ​​the first soft cushion 8 and the second soft cushion 9 is slightly larger than the area of ​​the fixed plate 1 and the adjusting plate 5, which can prevent the hinge from affecting the patient's sitting experience. The fixed plate 1 is fixed above the pressure shell 11 by the support rod 10. When the rotating rod 3 rotates, it can also drive the second rotating wheel 33 to rotate. Under the transmission action of the synchronous belt 32, it drives the first rotating wheel 31 to rotate on the outer surface of the U-shaped rod 30. At the same time, another synchronous belt 32 on the outer surface of the first rotating wheel 31 will drive the other second rotating wheel 33 to rotate, which simultaneously levels the lower adjusting plate 5. The hand support rod 28 and the infusion support plate 29 on the pressure shell 11 can help place the patient's arm receiving infusion in a proper position and prevent large displacement of the arm.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
