Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multifunctional chair for ophthalmic day surgery. Background Technology

[0002] With the development of ophthalmic day surgery and the continuous increase in the number of day surgeries, chairs are commonly used in day wards instead of inpatient beds to make full use of space. Currently, the chairs used in ophthalmic day wards are generally standard sofas purchased from the market, with a small number being special models designed many years ago with professional structures and functions. Both of these types of chairs have relatively simple structures and functions, and are no longer sufficient to meet the postoperative needs of ophthalmic day surgery patients at this stage.

[0003] During ophthalmic surgery, some patients require a specific postoperative position for a period of time (ranging from several days to several months) to ensure the best surgical outcome. For example, some patients undergoing retinal surgery need to maintain a strictly downward-facing position, while some patients undergoing corneal surgery need to maintain a strictly upward-facing position. Currently available day surgery chairs cannot simultaneously meet the needs of both positions.

[0004] To address these issues, there is an urgent need for a chair that can adapt to the postoperative positioning needs of patients undergoing different eye surgeries. This would improve patient compliance in maintaining correct positioning after surgery, thereby maximizing the effectiveness of the procedure. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional chair for ophthalmic day surgery to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional chair for ophthalmic day surgery, comprising an electric sofa, wherein the electric sofa is equipped with: a control mechanism disposed at the headrest position of the electric sofa; two cushions symmetrically mounted on the moving end of the control mechanism; two limiting tracks respectively located at the armrest positions on both sides of the electric sofa; a lifting mechanism installed at the two limiting tracks; a reclining platform disposed at the moving end of the lifting mechanism and matching the limiting tracks; and an IV stand installed behind the armrest position of the electric sofa.

[0007] In one feasible implementation, the control mechanism includes: a dual-axis motor, threaded rods, and limiting guide rails. The dual-axis motor is installed on the inner side of the electric sofa headrest. One end of each of the two threaded rods is rotatably installed on the inner side of the headrest position, and the other end is connected to the drive end of the dual-axis motor. The two threaded rods are screwed to the middle part of the two soft pads. The two limiting guide rails are respectively installed at the headrest position and are inserted into the two soft pads.

[0008] In one feasible implementation, corrugated tubes are respectively provided on the outer side of the outer wall of the two threaded rods, and the inner ends of the corrugated tubes are respectively connected between the inner side of the headrest position and the soft cushion.

[0009] In one feasible implementation, the lifting mechanism includes: a lead screw module, two lead screw modules being vertically installed at the two limiting rails respectively; and a movable seat, two movable seats being installed on the movable ends of the two lead screw modules respectively, with the top of one movable seat rotatably connected to the platform and the other movable seat overlapping the platform.

[0010] In one possible implementation, the electric sofa has a recess in the middle of the headrest area.

[0011] In one possible implementation, the platform is matched with one of the limiting tracks and moves vertically along the limiting track.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: This device, by integrating an improved downward-facing chair and an upward-facing positioning assistive structure, achieves comprehensive adaptation to the positioning needs of patients after different eye surgeries. The improved downward-facing chair allows patients to easily adopt the necessary positions, while the newly added upward-facing positioning assistive structure provides support for patients who need to adopt the opposite position. The introduction of the electric sofa structure allows patients to easily adjust the angle and position of the sofa to suit their comfort and medical needs. The electric adjustment function reduces reliance on medical staff and improves patients' ability to adjust their own positions, thereby enhancing postoperative positioning compliance. Electric adjustment also helps reduce discomfort and stress for patients when adjusting their positions, which is crucial for postoperative recovery. This device not only improves patient comfort and helps ensure surgical results, but also reduces inconvenience and potential medical risks when adjusting positions. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a multifunctional chair for ophthalmic day surgery, including an electric sofa 1. The electric sofa 1 is equipped with a control mechanism, cushions 2, limiting rails 3, a lifting mechanism, a reclining platform 4, and an IV stand 5. The control mechanism is located at the headrest position of the electric sofa 1; two cushions 2 are symmetrically installed on the moving end of the control mechanism; two limiting rails are respectively opened at the armrest positions on both sides of the electric sofa; the lifting mechanism is installed at the two limiting rails; the reclining platform 4 is located at the moving end of the lifting mechanism and matches the limiting rails 3; the IV stand 5 is installed behind the armrest position of the electric sofa 1.

[0020] In practical implementation, it should be noted that patients can control the rotation of the backrest and footrest 13 of the electric sofa 1 via an external control panel or controller. This also activates the dual-axis motor 6 and the lead screw module 10. The control technology of the electric sofa 1 is well-known in the field and has not been elaborated upon here. During use, patients adjust the angle and position of the sofa through the control mechanism to adapt to different body positions. The cushions 2 are symmetrically installed on the moving end of the control mechanism, providing additional support and comfort for the patient. The symmetrical arrangement of the cushions 2 supports the patient's head and provides comfort when the patient is in a supine position. The limiting track 3 is located at the armrest position of the electric sofa 1, and the lifting mechanism ensures the stable movement of the prone platform 4 on the limiting track 3. The lifting mechanism, installed on the limiting track 3, allows the prone platform 4 to rise or fall as needed. The armrest depth of the electric sofa is greater than the seat depth to accommodate the patient's downward-facing position. The prone platform 4 is located at the moving end of the lifting mechanism and matches the limiting track 3, ensuring the patient can safely lie prone. The IV stand 5 is installed behind the armrest of the electric sofa 1, making it convenient for patients to use when they need IV infusion after surgery.

[0021] This multi-functional day surgery chair in our ophthalmology department offers a high degree of adjustability and comfort through the combination of an electric sofa 1 and a control mechanism, meeting the needs of patients in different postoperative positions. Specifically, the symmetrical installation of the cushions 2 enhances support, while the coordination of the limiting rails 3 and the lifting mechanism ensures the stable raising and lowering of the table 4, providing appropriate support for patients in both downward and upward positions. The IV stand 5 makes the entire chair not only fully functional but also easy to operate, effectively improving postoperative patient comfort and positional compliance, and helping to ensure surgical outcomes.

[0022] In some examples, the control mechanism further includes: a dual-axis motor 6, threaded rods 7, and limiting guide rails 8. The dual-axis motor 6 is installed on the inner side of the headrest of the electric sofa 1; one end of each of the two threaded rods 7 is rotatably installed on the inner side of the headrest position, and the other end is connected to the drive end of the dual-axis motor 6. The two threaded rods 7 are screwed to the middle part of the two soft pads 2; the two limiting guide rails 8 are respectively installed at the headrest position and are inserted into the two soft pads 2.

[0023] In the specific implementation process, it should be noted that the dual-axis motor 6 is installed on the inner side of the headrest of the electric sofa 1. When the dual-axis motor 6 is started, it drives two threaded rods 7 to rotate. One end of each threaded rod 7 is rotatably installed on the inner side of the headrest, and the other end is connected to the drive end of the dual-axis motor 6. The rotation of the threaded rods 7 then pushes the cushion 2 to move relative to or in opposite directions. At the same time, during the movement, the movement of the cushion 2 is constrained by two limiting guide rails 8. The two limiting guide rails 8 are respectively installed at the headrest position and are inserted into the cushion 2, ensuring that the cushion 2 moves along a predetermined path, thereby achieving adjustment of the support for the patient's head and back.

[0024] The control mechanism can accurately adjust the position and angle of the cushion 2 to suit the needs of different patients. The use of a dual-axis motor 6 provides power, making the adjustment process easier and faster. The rotation of the threaded rod 7 and the screw connection design with the cushion 2 make the support adjustment more accurate and controllable. The presence of the limiting guide rail 8 ensures the stability and safety of the cushion 2's movement, preventing excessive movement or accidental slippage. This device achieves precise control over the support for the patient's head and back, improving the chair's adaptability and comfort, and helping patients maintain correct posture after surgery.

[0025] In some examples, furthermore, corrugated tubes 9 are respectively provided on the outer walls of the two threaded rods 7. The inner ends of the corrugated tubes 9 are connected between the inner side of the headrest and the cushion 2. During the operation of the control mechanism, when the dual-axis motor 6 starts and drives the threaded rods 7 to rotate, the corrugated tubes 9 also move accordingly. The main purpose of the corrugated tubes 9 is to prevent the patient's hair from being caught in the threaded rods 7 when adjusting the sofa position. Due to the flexibility and protective function of the corrugated tubes 9, even if the threaded rods 7 come into contact with the patient's head during rotation, the corrugated tubes 9 can provide a safe barrier to prevent hair from getting tangled in the threaded part of the threaded rods 7. This significantly improves the safety of the electric sofa 1 and the comfort of the patient. The presence of the corrugated tubes 9 not only prevents the potential danger of hair getting caught, but also reduces the direct contact between the threaded rods 7 and the patient's head, thereby reducing discomfort. In addition, the setting of the corrugated tubes 9 also helps to protect the threaded rods 7 themselves, preventing damage due to friction during long-term use, ensuring the comfort and safety of the patient during use.

[0026] In some examples, the lifting mechanism further includes: two screw modules 10 and two movable seats 11. The two screw modules 10 are respectively vertically installed at the two limit rails 3; the two movable seats 11 are respectively installed on the movable ends of the two screw modules 10, and the top of one movable seat 11 is rotatably connected to the platform 4, and the other movable seat 11 overlaps with the platform 4.

[0027] In the specific implementation process, it should be noted that the lifting mechanism provides vertical driving force. When the lead screw module 10 is activated, the movable seat 11, mounted on the movable end of the lead screw module 10, moves up and down with the movement of the lead screw module 10. The top of the movable seat 11 is rotatably connected to the lying table 4. When the movable seat 11 moves upward, one end of the lying table 4 rests on the movable seat 11 at the other end of the electric sofa's armrest, allowing the patient to face the hole in the middle of the lying table 4. When the lying table 4 moves vertically, it matches the limiting track 3 to ensure the stability of the lying table 4 during movement. When using the lying table 4, the lead screw module 10 is activated first, and then the lying table 4 is flipped, greatly saving space and facilitating operation. The setting of the lying table 4 is crucial for patients who need to face downward. When the patient is tall, the lead screw module 10 can continuously rise, driving the platform 4 to move upwards. This allows the platform 4 to rise as needed, improving the adaptability of the chair to meet the needs of different patients, thus enhancing patient comfort and surgical outcomes. The use of the limiting rail 3 ensures the safety of the lifting mechanism during movement, preventing accidental slippage or excessive movement, thereby protecting patient safety.

[0028] In some examples, the electric sofa 1 has a recess 12 in the middle of the headrest position, which is used to place the back of the patient's head and make the patient more comfortable when lying on their back.
