The first lumbar and back placement opening 32 is used to place the lumbar and back of a hunchback patient. The first relief groove 31 is connected to the first lumbar and back placement opening 32.

[0041] Headrest 4 is installed at one end of the first adjustment part 12. The first adjustment part 12 can pass through the first relief groove 31 and the first lumbar support opening 32 in its sliding path.

[0042] The first direction and the second direction are perpendicular to each other.

[0043] Based on the above technical solution, the backrest 3 is provided with a first lumbar support opening 32 in the middle for supporting the back of hunchback patients. The first adjustment part 12 can pass through the first relief groove 31 and the first lumbar support opening 32 in its sliding path. For hunchback patients, the first lumbar support opening 32 provides a dedicated lumbar support space. For children, since children are generally shorter, their heads are generally located in the middle of the backrest 3. The headrest 4 can slide and adjust along the first direction with the first adjustment part 12, passing through the first relief groove 31 to the first lumbar support opening 32, until the headrest 4 can well support the head and neck of the children. The first adjustment part 12 has a large adjustment range and can meet the usage needs of both adult and children.

[0044] Preferably, the first adjustment part 12 includes a first adjustment sleeve 121, a first adjustment rod 122 and a first locking valve 123. The first adjustment sleeve 121 is disposed on the frame 11 and extends along the first direction. One end of the first adjustment rod 122 is slidably inserted into the first adjustment sleeve 121. The first locking valve 123 is detachably installed on the first adjustment sleeve 121 and is used to lock the relative position between the first adjustment rod 122 and the first adjustment sleeve 121. The headrest 4 is disposed on the other end of the first adjustment rod 122.

[0045] The first adjustment part 12 includes a first adjustment sleeve 121 and a first adjustment rod 122. The first adjustment sleeve 121 is fixed to the frame 11 and extends along a first direction. One end of the first adjustment rod 122 is slidably inserted into the first adjustment sleeve 121. The headrest 4 can be smoothly and precisely slidably adjusted along the first direction to meet the personalized needs of different patients for head support position, thereby improving comfort and support effect. The first locking valve 123 is detachably installed on the first adjustment sleeve 121 and is used to lock the relative position between the first adjustment rod 122 and the first adjustment sleeve 121. After the headrest 4 is adjusted to the ideal position, the position of the first adjustment rod 122 is quickly fixed by the first locking valve 123 to prevent the headrest 4 from accidentally sliding due to external force or vibration during use, and to ensure that the patient's head is continuously and stably supported.

[0046] More preferably, the first adjusting part 12 further includes a second adjusting rod 124, a second locking valve 125, a third adjusting rod 126, and a third locking valve 127. One end of the second adjusting rod 124 is hinged to the other end of the first adjusting rod 122. The second locking valve 125 is disposed at the hinge between the first adjusting rod 122 and the second adjusting rod 124 and is used to lock the relative position between the second adjusting rod 124 and the first adjusting rod 122. One end of the third adjusting rod 126 is hinged to the other end of the second adjusting rod 124. The third locking valve 127 is disposed at the hinge between the second adjusting rod 124 and the third adjusting rod 126 and is used to lock the relative position between the third adjusting rod 126 and the second adjusting rod 124. The pivots at the hinges of the first adjusting rod 122 and the second adjusting rod 124, and the pivots at the hinges of the second adjusting rod 124 and the third adjusting rod 126, both extend in the third direction.

[0047] The headrest 4 is installed on the other end of the third adjusting rod 126, and the headrest 4 is set on the other end of the first adjusting rod 122 via the third adjusting rod 126 and the second adjusting rod 124.

[0048] Among them, the first direction, the second direction, and the third direction are all perpendicular to each other.

[0049] A second locking valve 125 and a third locking valve 127 are respectively hinged between the first adjusting rod 122 and the second adjusting rod 124, and between the second adjusting rod 124 and the third adjusting rod 126. Each rotating shaft extends along the third direction, so that the head pillow 4 can not only be adjusted by translation along the first direction, but also achieve various rotational adjustments through the hinges, thereby better conforming to the physiological curves of different patients' heads and necks and achieving a precise support effect. When the head pillow 4 is adjusted to the ideal position, the second locking valve 125 and the third locking valve 127 lock the hinged parts, which can effectively prevent the head pillow 4 from shifting due to external force or vibration, ensuring the stability of the adjusted position and the safety of the treatment.

[0050] Preferably, the bracket 1 further includes a second adjustment part 13. The backrest 3 is rotatably mounted on the frame 11. The second adjustment part 13 includes a second adjustment sleeve 131, a fourth adjustment rod 132, and a fourth locking valve 133. The second adjustment sleeve 131 is mounted on the frame 11. One end of the fourth adjustment rod 132 is slidably inserted into the second adjustment sleeve 131. One end of the fourth adjustment rod 132 is connected to the backrest 3. The fourth locking valve 133 is detachably mounted on the second adjustment sleeve 131 and is used to lock the relative position between the fourth adjustment rod 132 and the second adjustment sleeve 131.

[0051] The backrest 3 is rotatably mounted on the frame 11 and slides into the second adjusting sleeve 131 mounted on the frame 11 via the fourth adjusting rod 132, thereby adjusting the angle between the backrest 3 and the seat 2. Medical staff can adjust the tilt angle of the backrest 3 according to the patient's needs to obtain back support that better suits the patient's comfort, ensuring patient comfort and the support effect of the backrest 3 and seat 2. The fourth locking valve 133 is detachably mounted on the second adjusting sleeve 131 and is used to lock the relative position between the fourth adjusting rod 132 and the second adjusting sleeve 131. After adjusting to the ideal angle, the fourth locking valve 133 securely locks the fourth adjusting rod 132 and the sleeve, ensuring that the backrest 3 will not shift in angle due to external force or vibration during use, thus ensuring safe use.

[0052] More preferably, the second adjustment unit 13 also includes a foot pedal 134, which is movably mounted on the frame 11. The foot pedal 134 is connected to the fourth locking valve 133. Rotation of the foot pedal 134 can drive the fourth locking valve 133 to lock or unlock the fourth adjustment rod 132 and the second adjustment sleeve 131.

[0053] Specifically, the second adjustment part 13 also includes a transmission rod, a transmission rope, and a reset member. The two ends of the transmission rod are respectively hinged to the foot pedal 134 and one end of the transmission rope. The other end of the transmission rope is connected to the fourth locking valve 133. The two ends of the reset member are respectively connected to the fourth locking valve 133 and the second adjustment sleeve 131. The reset member is a reset spring.

[0054] When a medical staff member steps on foot pedal 134, foot pedal 134 rotates relative to frame 11, causing transmission rod to move downward. Transmission rod pulls transmission rope, and fourth locking valve 133 moves away from fourth adjusting rod 132, overcoming the elastic force of reset member. Fourth adjusting rod 132 disengages from second adjusting sleeve 131 and can slide along the axial direction of second adjusting sleeve 131 to adjust the position between fourth adjusting rod 132 and second adjusting sleeve 131. After adjustment, foot pedal 134 is released, and elastic force of reset member drives fourth locking valve 133 to move toward fourth adjusting rod 132. Fourth adjusting rod 132 relocks with second adjusting sleeve 131. Elastic force of reset member sequentially drives transmission rope, transmission rod, and foot pedal 134 to reset.

[0055] The foot pedal 134 and the fourth locking valve 133 form a transmission chain through a transmission rod, a transmission rope, and a return spring. Medical staff only need to step on the foot pedal 134 to drive the entire system, thereby locking or unlocking the fourth adjusting rod 132 and the second adjusting sleeve 131 through the fourth locking valve 133. In a medical environment, medical staff often need to free their hands for other operations. Using the foot pedal for adjustment not only improves the convenience of operation but also reduces the risk of cross-contamination, while meeting the need for manual operation.

[0056] Preferably, the eye-washing chair also includes a back cushion 5, which is disposed on the backrest 3. The back cushion 5 is provided with a second relief groove 51 and a second lumbar and backrest placement opening 52 connected to the first relief groove 31 and the first lumbar and backrest placement opening 32 of the backrest 3.

[0057] More preferably, the back pad 5 is made of antibacterial memory foam, and its surface is covered with breathable mesh fabric. The edge of the second lumbar support opening 52 is provided with a silicone pad, and the thickness of the silicone pad gradually decreases from the outside to the inside to adapt to the lumbar curvature of hunchback patients.

[0058] The backrest 5 is mounted on the backrest 3, and a second relief groove 51 and a connected second lumbar support opening 52 are provided corresponding to the first relief groove 31 and the first lumbar support opening 32 of the backrest 3. A silicone pad is added to the edge of the second lumbar support opening 52, with its thickness gradually decreasing from the outside to the inside. This allows the backrest 5 to specifically adapt to the lumbar curvature of hunchback patients, forming zoned support. It conforms to the natural curve of the human body and effectively distributes pressure on the lower back, improving overall support and ensuring the comfort of hunchback patients. The backrest 5 is made of antibacterial memory foam and covered with breathable mesh fabric. The antibacterial memory foam effectively inhibits bacterial growth, maintaining a hygienic environment; while the breathable mesh fabric ensures good breathability during prolonged use, preventing discomfort caused by stuffiness, thereby improving the user experience.

[0059] Preferably, the bottom of the bracket 1 is provided with an anti-slip base 6, and the bottom edge of the anti-slip base 6 extends outward with a supporting flange.

[0060] The bottom of the bracket 1 is equipped with an anti-slip base 6, which can effectively prevent the eyewash chair from sliding due to wet ground or external force during use, thereby improving structural stability and safety. The bottom edge of the anti-slip base 6 extends outward with a support flange, which further expands the contact area between the base and the ground, disperses and bears more external force, thereby preventing the equipment from tilting or shifting, and ensuring that the structure is more solid and stable.

[0061] In summary, this utility model embodiment provides an eye-washing chair, in which a first lumbar support opening 32 is provided in the middle of the backrest 3 for supporting the lumbar and back of a hunchback patient. The first adjustment part 12 can pass through the first relief groove 31 and the first lumbar support opening 32 in its sliding path. For hunchback patients, the first lumbar support opening 32 provides a dedicated lumbar support space. For children, since children are generally shorter, their heads are generally located in the middle of the backrest 3. The headrest 4 can slide and adjust along the first direction with the first adjustment part 12, passing through the first relief groove 31 to the first lumbar support opening 32, until the headrest 4 can well support the head and neck of the children. The first adjustment part 12 has a large adjustment range and can meet the usage needs of both adult and children.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
