Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example 1:

[0028] See attached document Figure 1-4 The outpatient injection chair shown includes a seat 1, a backrest 2, a first armrest 5, a second armrest 29, a multi-functional table and chair 10, and an infusion stand 3. The backrest 2 is connected to the seat 1, and the infusion stand 3 is connected to the seat 1. The first armrest 5 and the second armrest 29 are respectively provided on both sides of the seat 1. The multi-functional table and chair 10 is movably arranged on one side of the seat 1.

[0029] Specifically, the multifunctional table and chair 10 includes a tabletop 101 and a seat 102. The tabletop 101 and the seat 102 are connected to form an L-shaped structure. Multiple hinges 9 are provided on the outer side of the first armrest 5 and the seat 102 for the multifunctional table and chair 10 to rotate up and down.

[0030] The multifunctional table and chair 10 is equipped with a positioning and adjustment mechanism, which is used to fix the multifunctional table and chair 10 after it is folded upward. The positioning and adjustment mechanism includes two support seats 8 disposed on the seat 1, and two first support rods 13 movably disposed on the multifunctional table and chair 10. The multifunctional table and chair 10 is equipped with an adjustment component for adjusting the position of the first support rods 13.

[0031] The support base 8 is fixedly installed on the outer side of the first handrail 5 to support the first support rod 13.

[0032] A first through hole 16 is provided inside the junction of the desktop 101 and the chair surface 102, and the first support rod 13 is slidably installed inside the junction of the desktop 101 and the chair surface 102 through the first through hole 16.

[0033] The adjustment assembly includes a first rotating rod 19, a second knob 12, a bearing 20, and an adjustment disc 30. A third mounting groove 17 is provided on the desktop 101, and the first rotating rod 19 is connected to the desktop 101 through the third mounting groove 17. The bottom of the first rotating rod 19 is provided with a thread 23, and the bottom of the third mounting groove 17 is provided with a threaded groove that matches the thread 23.

[0034] The adjusting disc 30 is rotatably sleeved on the first rotating rod 19, and the adjusting disc 30 has a truncated cone structure. The end faces of the two first support rods 13 are inclined surfaces and are slidably connected to the side of the adjusting disc 30.

[0035] The adjustment plate 30 is provided with a fourth mounting groove 31. The adjustment plate 30 and the first rotating rod 19 are rotatably connected by a bearing 20, and the bearing 20 is installed in the fourth mounting groove 31.

[0036] A slider 21 is fixedly connected to the adjustment disk 30. A groove 22 is provided on the inclined surface of the end of the first support rod 13. The slider 21 and the groove 22 are slidably connected, so that the adjustment disk 30 can drive the first support rod 13 to slide left and right during the up and down movement, extending out of the table 101 or retracting into the table 101.

[0037] The second knob 12 is fixedly installed on the upper end of the first rotating rod 19. By rotating the second knob 12, the first rotating rod 19 and the adjusting plate 30 can be moved down simultaneously. The downward movement of the adjusting plate 30 causes the slider 21 to slide in the sliding groove 22, thereby pushing the first support rod 13 out of the first through hole 16 and placing the first support rod 13 on the support base 8 to support the multifunctional table and chair 10. When the first rotating rod 19 moves upward, it drives the adjusting plate 30 to move upward, which can pull the first support rod 13 and retract it into the tabletop 101, thereby allowing the entire multifunctional table and chair 10 to rotate.

[0038] The front end of the first handrail 5 is provided with a cup groove 11. The depth and diameter of the cup groove 11 are optimized to securely hold a water cup and prevent the patient from accidentally knocking over the water cup during treatment, which would affect the treatment process.

[0039] The second armrest 29 is equipped with multiple straps 6 for securing the patient's arm. During actual treatment, some patients, especially those who have consumed alcohol or are children, may find it difficult to keep their arms on the second armrest 29 for extended periods, which can affect the progress of the injection treatment. The straps 6 effectively solve this problem by securing the patient's arm. The straps 6 feature a Velcro design for easy operation.

[0040] The inner side of the second handrail 29 is provided with a storage slot 18, which can be used to store some of the patient's personal items, such as mobile phones and keys. It can also be used to store medical tools and medicines, reducing the time that medical staff spends retrieving medical tools and medicines, reducing the workload of medical staff, and improving treatment efficiency.

[0041] The second handrail 29 has a first mounting groove 14 at its rear end. The infusion support 3 is movably mounted at the rear end of the second handrail 29 through the first mounting groove 14. The top of the infusion support 3 is fixedly connected with multiple fixing hooks 4 to fix infusion bottles, bags or syringes and other instruments, so as to avoid the situation where the liquid flow rate is too fast or too slow due to the swing of the instruments during infusion treatment, thereby ensuring the stability and safety of the infusion process. Example 2:

[0042] See attached document Figure 5-7 The outpatient injection chair shown includes a backrest adjustment mechanism and a telescopic guardrail 32.

[0043] To reduce patient discomfort during treatment, both the chair back 2 and the chair seat 1 are ergonomically designed. The chair back 2 and the chair seat 1 are rotatably connected. The chair back 2 is equipped with a backrest adjustment mechanism, which can freely adjust the angle of the chair back 2 according to the patient's needs.

[0044] The backrest adjustment mechanism includes a first knob 7, a second rotating rod 24, a bevel gear 25, an arc gear 26, a third rotating rod 27, and a second support rod 28. The first knob 7 is fixedly installed on the upper end of the second rotating rod 24. A second mounting groove 15 is provided at the rear end of the first armrest 5. The second rotating rod 24 is rotatably installed on the rear end of the first armrest 5 through the second mounting groove 15. The bevel gear 25 is fixedly installed on the lower end of the second rotating rod 24.

[0045] The third rotating rod 27 is located between the seat 1 and the backrest 2. The second support rod 28 is embedded inside the backrest 2. The third rotating rod 27 and the second support rod 28 are fixedly connected at a 90-degree angle. The arc gear 26 is fixedly installed at the end of the third rotating rod 27 and meshes with the bevel gear 25. Thus, when the first knob 7 is rotated, the arc gear 26, the third rotating rod 27 and the second support rod 28 can be rotated simultaneously, thereby achieving precise rotation control of the angle of the backrest 2.

[0046] A telescopic guardrail 32 is fixedly connected to the side of the chair back 2. The telescopic guardrail 32 includes a fixed rod 33 and a movable rod 34. A limiting mechanism is provided on the telescopic guardrail 32. The limiting mechanism includes a limiting buckle 35 on the fixed rod 33 and a limiting ball 36 on the movable rod 34. When the chair back 2 is rotated to be flush with the chair seat 1 by the second knob 12, the movable rod 34 of the telescopic guardrail 32 can be pulled up. When the limiting ball 36 is engaged in the limiting buckle 35, the movable rod 34 can be in a stable raised state to prevent the patient lying flat from falling off the injection chair.

[0047] The working principle of an outpatient injection chair in this utility model is as follows: the patient or doctor rotates the second knob 12, which drives the first rotating rod 19 and the adjustment plate 30 to move up and down synchronously. The design of the bearing 20 makes the adjustment plate 30 not rotate synchronously with the first rotating rod 19. The up and down movement of the adjustment plate 30 drives the slider 21 to slide in the slide groove 22, thereby pushing or pulling the first support rod 13 out of the first through hole 16. When the first rotating rod 19 moves downward, it causes the adjusting plate 30 to move downward, thereby pushing the first support rod 13 out of the first through hole 16 and placing it on the support base 8. At this time, the tabletop 101 of the multifunctional table and chair 10 faces upward. The tabletop 101 can be used by patients for writing or reading while waiting or receiving treatment, facilitating the filling out of medical records, signing documents, or reading information. It also integrates functions such as placing items and arm support. When the first rotating rod 19 moves upward, it causes the adjusting plate 30 to move upward, thereby pulling the first support rod 13 into the first through hole 16 and bringing the outer side of the tabletop 101 into contact with the ground. At this time, the chair surface 102 faces upward, allowing accompanying persons to sit comfortably, reducing the time spent moving chairs back and forth, improving efficiency, and saving space. In actual treatment, the multifunctional table and chair 10 can be transformed into a table or chair as needed to meet the needs of patients in different treatment scenarios.

[0048] The patient or doctor rotates the first knob 7, which in turn rotates the second rotating rod 24. A bevel gear 25 and an arc gear 26, fixedly connected to the lower end of the second rotating rod 24, mesh with each other. The rotation of the second rotating rod 24 drives the bevel gear 25 to rotate, which in turn drives the arc gear 26 to rotate. The rotation of the arc gear 26 is further transmitted to the third rotating rod 27, thereby rotating the second support rod 28 inside the chair back 2. The rotation of the second support rod 28 acts on the chair back 2, changing its angle and reducing patient discomfort during treatment. When the chair back 2 is adjusted to be 180 degrees flush with the seat 1, the telescopic guardrail 32 can be pulled up to prevent the patient lying flat from falling off the injection chair.

[0049] The outpatient injection chair described in this application is made of high-quality alloy material, making it sturdy and durable. While lightweight, it also possesses excellent corrosion resistance, ensuring safety and stability for long-term use. The surface is made of professional, easily disinfectable leather, which is comfortable to the touch, antibacterial, stain-resistant, and easy to clean, effectively meeting the high hygiene standards required in medical environments.
