Description

Technical Field

[0001] This application relates to the field of infusion chair technology, and in particular to an infusion chair with a function of converting between a seat and a bed. Background Technology

[0002] Currently, hospital infusion rooms mainly use infusion chairs with fixed or semi-reclining adjustment structures for infusion operations. However, when faced with sudden illness during infusion, these chairs cannot provide a flat reclining function. Medical staff have to borrow mobile beds from other departments, move the patient to the bed, and then move them to the operating room for examination and operation. This process is not only time-consuming and laborious, but may also aggravate the patient's condition due to the bumps during transportation, affecting the efficiency of treatment. Utility Model Content

[0003] The problem this application aims to solve is that the infusion chairs in existing hospital infusion rooms cannot be used for lying flat, and that additional beds need to be arranged for the transfer of patients who suddenly fall ill during the infusion process.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a lightweight dual-purpose infusion chair, including a support frame, including a long end arranged vertically and equipped with casters at the end, a connecting pipe arranged on one side of the support frame for connecting to another support frame, forming an H-shaped support frame assembly; the support frame assembly includes a first support frame assembly and a second support frame assembly, the first support frame assembly and the second support frame assembly are arranged opposite to each other, and the long end of the second support frame assembly is provided with a hanging bracket that can be vertically extended in stages; the frame structure includes a first frame and a second frame, the first frame and the second frame are connected by a machine The components are arranged in an obtuse angle and are connected by a U-shaped interlocking mechanism. The first frame is fixedly positioned on top of the first support assembly. The tie rod structure includes a rod body and a sleeve. One end of the rod body is fixed to the short end of the first support assembly, and one end of the sleeve is fixed to the short end of the second support assembly. The rod body and the sleeve are telescopically connected. The locking structure includes a groove on the first frame, a rod that engages with the groove, and a hole on the second frame. The rod is slidably positioned in the groove and has a protrusion at one end. The protrusion engages with a slot in the groove to lock the first and second frames.

[0005] Furthermore, it also includes a short end that forms an L-shaped structure with the long end, the short end being horizontally arranged and fixedly connected to the long end to provide stable support.

[0006] Furthermore, the bracket extends in stages via an internal thread connection, and the top is equipped with a hook for hanging medicine bottles.

[0007] Furthermore, the upper part of the round tubes of the first and second frames is provided with soft pads, which are fixed by straps, and the interior is provided with support tubes to support the soft pads.

[0008] Furthermore, the sliding groove of the locking mechanism is arranged along the axial direction of the circular tube and is provided with multiple vertically spaced slots. After the protrusion of the insertion rod engages with the slot, it achieves locking through circumferential rotation.

[0009] Furthermore, handles are symmetrically arranged at the distal ends of the first and second frames. The handles are connected to the round tubes via bearings and can switch between a natural hanging state and a usage state.

[0010] Furthermore, an auxiliary wheel for providing movement support is provided at the middle position of the upper part of the circular tube of the first frame.

[0011] Furthermore, the upper part of the rod is provided with outwardly protruding steel balls at intervals, and the inside of the rod is provided with springs that lift the steel balls. One end of the upper part of the rod sleeve is provided with a slot that matches the steel balls. The steel balls and the slot of the rod sleeve cooperate to restrict the movement of the rod.

[0012] Furthermore, both the first frame and the second frame are composed of support tubes and insert tubes. One end of the support tube is sleeved with the insert tube. The upper part of the support tube has a groove similar to that of the rod sleeve. The upper part of the insert tube is equipped with steel balls and springs similar to those of the rod body.

[0013] Because the infusion chair of this application is designed with a support frame, a frame structure, a tie rod structure, and a locking structure, it can be used as a regular infusion chair and can also be quickly converted into a bed structure in an emergency, facilitating the rapid transfer of patients with sudden illnesses. This solves the problem that infusion chairs in existing hospital infusion rooms cannot achieve a lying-down function, and that additional beds need to be arranged for the transfer of patients with sudden illnesses during infusion.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Example 1

[0021] This application relates to a lightweight dual-purpose infusion chair, such as Figure 1 As shown, the infusion chair includes a support frame, a hanging bracket 8, and a frame (first frame 1 and second frame 11). The support frame is divided into a long end 7 and a short end 6 forming an L-shaped structure. The long end 7 is arranged vertically and has casters 9 connected to it at the end for moving the infusion chair. The short end 6 is arranged horizontally and fixedly connected to the long end 7 to provide stable support. A connecting pipe 12 is arranged on one side of the support frame for connecting another support frame to form an H-shaped support frame group. There are two support frame groups, namely a first support frame group 13 and a second support frame group 21, which are arranged opposite to each other to enhance overall stability and facilitate walking. The long end 7 of the second support frame group 21 has a hanging bracket 8 arranged on the outside. The hanging bracket 8 is connected by an internal thread for step-by-step vertical extension. The top extends outward with a hook 5 for hanging medicine bottles.

[0022] The first support frame 1 is arranged on the top of the first support frame 13. The first frame 1 is a square structure composed of round tubes. Handrails 2 are symmetrically arranged on both sides along the length direction to support the patient's arms or limit the displacement of the buttocks. A soft pad 3 is arranged on the upper part of the first frame 1. The two ends can be tied to the upper part of the round tubes by straps. Support tubes are arranged at intervals inside to support the soft pad 3. A second frame 11 with the same structure is arranged on one side of the first frame 1. The two are arranged at an obtuse angle. I-shaped connecting sleeves 4 are sleeved on the upper part of the adjacent round tubes to achieve a transition connection. The second frame 11 needs to be arranged against the wall to achieve support. The casters 9 are in the locked state.

[0023] A stretchable and retractable tie rod structure, consisting of a rod body 20 and a rod sleeve 14, is arranged between the first support frame group 13 and the second support frame group 21. It is used to adjust the distance between the two support frame groups. One end of the rod body 20 is fixedly connected to the short end 6 of the support frame of the first support frame group 13, and one end of the rod sleeve 14 is fixedly connected to the short end 6 of the support frame of the second support frame group 21. The other ends of the rod body 20 and the rod sleeve 14 are sleeved together. The round tube rods of the frame are rotatably connected to the connecting sleeve 4 respectively, so that the second frame 11 can be laid flat and overlapped on the second support frame group 21, realizing the quick conversion from seat to bed.

[0024] This infusion chair integrates the functions of a seat and a bed, meeting daily infusion needs while quickly converting into a bed in emergencies for easy patient transport. The frame design, featuring a pull rod structure and rotating connection, allows for rapid conversion between seat and bed, making operation simple and quick. It eliminates the need for additional mobile beds, allowing for direct transport using the lightweight, dual-purpose infusion chair, significantly reducing transport time and enabling the rapid transfer of patients with emergencies to the operating room or designated locations, thus gaining valuable time for treatment and improving efficiency. Example 2

[0025] To further enhance the stability of the bed structure and ensure that patients receive safe and stable support during transport, such as... Figure 2 As shown, a unique locking mechanism is designed between the first frame 1 and the second frame 11. The upper part of the first frame 1 near the connecting sleeve 4 has a sliding groove 18 arranged along the axial direction of the circular tube. These sliding grooves 18 not only provide a sliding track for the insertion rod 16, but also realize the locking function through their special internal structure. The sliding grooves 18 are arranged vertically at intervals and side by side with slots 19 that communicate with them. These slots 19 are used to cooperate with the protrusions 17 on the insertion rod 16 to realize locking.

[0026] The slide groove 18 has a sliding rod 16 inside, which can slide along it. One end of the rod 16 is designed with a protrusion 17 extending vertically. This protrusion 17 is the key part of the locking mechanism. When the rod 16 slides along the slide groove 18 to the predetermined position, the protrusion 17 will be ready to be inserted into the slot 19. At the position of the circular tube on the upper part of the second frame 11 corresponding to the rod 16, there is a hole 15. This hole 15 cooperates with the rod 16, so that the rod 16 can be smoothly inserted into it. After the rod 16 is inserted into the hole 15, by rotating the rod 16 circumferentially, the protrusion 17 will be inserted into the slot 19, thereby realizing the relative fixation between the first frame 1 and the second frame 11.

[0027] This design effectively limits the relative angular flipping operation between the second frame 11 and the first frame 1. Even if the patient encounters bumps or instability during transport, the bed structure can maintain stable horizontal support, ensuring the patient's safety and comfort.

[0028] Converting to a bed structure: First, unlock the casters 9 and move the lightweight dual-purpose infusion chair to a suitable position. Then, stretch the pull rod structure and adjust the distance between the first support group 13 and the second support group 21 to prepare for the frame to be laid flat. Next, rotate the first frame 1 and the second frame 11 so that they gradually lie flat and overlap the upper part of the second support group 21. Finally, slide the insertion rod 16 to the position of the insertion hole 15 and rotate the insertion rod 16 circumferentially so that the protrusion 17 is inserted into the slot 19 to lock the first frame 1 and the second frame 11.

[0029] To restore the seat structure: First, rotate the insert rod 16 in the opposite direction to dislodge the protrusion 17 from the slot 19. Then, slide the insert rod 16 away from the insertion hole 15. Next, lift the first frame 1 and the second frame 11 to restore them to an obtuse angle arrangement. Finally, retract the pull rod structure, adjust the distance between the first support group 13 and the second support group 21, and lock the caster 9.

[0030] The locking mechanism of the insertion rod 16 and the slot 19 effectively limits the relative angle of rotation between the first frame 1 and the second frame 11, improving the stability of the bed structure. The design of the insertion rod 16 and the insertion hole 15 makes locking and unlocking operations very simple, allowing medical staff to quickly complete the conversion operation. The stable bed structure provides safe support for patients and reduces the risks that may be caused by bumps or instability during transportation. Example 3

[0031] To further optimize the functionality of the lightweight dual-purpose infusion chair, especially when using the bed structure for patient transport, such as... Figure 1 As shown, outwardly extending handles 10 are symmetrically arranged at the distal ends of the first frame 1 and the second frame 11. This design takes into account the needs of medical staff in actual operation and aims to provide a more convenient and efficient way to move patients. The handles 10 are located at the distal ends of the first frame 1 and the second frame 11, that is, at the end away from the connecting sleeve 4 and the support frame assembly. The outward extension design of the handles 10 ensures that medical staff can maintain sufficient operating space when holding them and avoid interference with other parts of the bed. At the same time, the symmetrical arrangement of the handles 10 allows for pushing operations at both ends of the bed, improving the flexibility and adaptability of the transfer.

[0032] In practical use, when it is necessary to move a patient on the bed to another location, two medical staff can stand at opposite ends of the bed, hold the corresponding handles 10, and move the bed to the destination smoothly and quickly through coordinated directional pushing operations. This design not only reduces the physical burden on medical staff, but also improves the safety and stability during the transfer process.

[0033] The handle 10 is located at the distal end of the first frame 1 and the second frame 11, ensuring that medical staff can easily reach it during operation without colliding or interfering with other parts of the bed, thus making it easier and faster to push the bed and improving the efficiency of patient transfer. The handle 10 is designed with an ergonomic arc shape so that medical staff can hold it comfortably. By providing a stable grip point and operating space, the handle 10 design reduces the risk of improper operation during transfer. In terms of size, the length and diameter of the handle 10 have been calculated to ensure sufficient gripping force and operational stability. The handle 10 is made of durable and easy-to-clean materials, such as stainless steel or plastic, with a non-slip surface to increase friction during gripping and prevent slippage leading to operational errors. Example 4

[0034] To further improve patient stability when moving while seated, especially when healthcare workers need to push the chair through narrow spaces or uneven surfaces, such as... Figure 3 As shown, an auxiliary wheel 22 is arranged at the middle of the upper part of the round tube between the handles 10 on the first frame 1 to assist walking. This design aims to ensure the stability of the seat and the safety of the patient during movement by adding additional support points and movement assistance. The auxiliary wheel 22 is installed on the upper part of the round tube of the first frame 1, located in the middle between the two handles 10. This layout ensures that the auxiliary wheel 22 can effectively contact the ground during pushing and provide stable support, while avoiding interference with the operation of the handles 10, thus ensuring the convenience of operation for medical staff.

[0035] The design of the training wheels 22 takes into account a variety of usage scenarios and needs. They are made of wear-resistant and non-slip materials to ensure good grip and stability under different ground conditions. At the same time, the training wheels 22 also have a certain degree of steering flexibility, allowing the seat to easily handle turning and obstacle avoidance during movement. As an additional support point, the training wheels 22 effectively distribute the weight and pressure of the seat during movement, enhance the overall stability of the seat, and reduce swaying and tilting caused by uneven ground or uneven pushing force.

[0036] The design of the auxiliary wheels 22 and the handle 10 work together to form a convenient mobility system for the lightweight dual-purpose infusion chair. The handle 10 provides a grip point for medical staff to push the chair, while the auxiliary wheels 22 provide additional movement support and stability. The combination of the two allows medical staff to push the chair more easily and safely, providing high-quality transport services for patients. Example 5

[0037] To ensure the stability and reliability of the rod body 20 and the sleeve 14 during the opening and closing process, this application designs a unique limiting mechanism, such as... Figure 4 As shown, this mechanism, through the cooperation of steel balls 24 and springs, achieves appropriate resistance limiting operation of the rod body 20 and the sleeve 14 in the axial direction, effectively preventing the rod body 20 from sliding out or retracting on its own when not subjected to external force. Outwardly protruding steel balls 24 are arranged at intervals on the upper part of the rod body 20. These steel balls 24, as key components of the limiting mechanism, have their positions and numbers calculated to ensure uniform resistance during opening and retraction. To facilitate the arrangement of the steel balls 24 and the installation of the springs, the rod body 20 is designed as a hollow structure. This design not only reduces the weight of the rod body 20 but also improves its structural strength and stability. Inside the rod body 20, springs are arranged to lift the steel balls 24. The spring force and length are precisely adjusted to ensure that the steel balls 24 can maintain a certain pushing force when not subjected to external force. When the rod body 20 is opened or retracted, the springs will compress or extend accordingly according to the direction of movement of the rod body 20, thereby transmitting appropriate resistance through the steel balls 24.

[0038] To prevent the steel ball 24 from escaping from the slot formed on the upper part of the rod 20, the diameter of the steel ball 24 is designed to be larger than the width of the slot. This ensures that even when the rod 20 is subjected to a large external force, the steel ball 24 can be firmly held in the slot, ensuring the reliability of the limiting mechanism. At one end of the upper part of the sleeve 14, there are slots 23 for accommodating the steel ball 24. The position and shape of these slots 23 are matched with the steel ball 24 to ensure that the steel ball 24 can smoothly enter and lift. When the steel ball 24 is in the slot 23 of the sleeve 14, under the action of the spring, the surface of the steel ball 24 will be higher than the outer surface of the sleeve 14. This design not only enhances the connection stability between the rod 20 and the sleeve 14, but also provides a clear limit indication, allowing medical staff to easily determine whether the rod 20 and the sleeve 14 are in the correct position.

[0039] Pulling process: When medical staff need to pull the rod 20, they need to overcome the spring's pushing force on the steel ball 24 and pull the rod 20 out of the sleeve 14. During this process, the steel ball 24 will slide in the slot 23 and always maintain contact with the outer surface of the sleeve 14, providing appropriate resistance to prevent the rod 20 from being pulled out too quickly or too violently.

[0040] Storage process: When medical staff need to store the rod 20 back into the sleeve 14, they also need to overcome the spring force and push the rod 20 into the sleeve 14. The steel ball 24 will slide in the opposite direction in the slot 23 and always maintain close contact with the outer surface of the sleeve 14, ensuring that the rod 20 can be stably stored in the sleeve 14.

[0041] When the rod 20 is in its extended or retracted position, the steel ball 24 will be pressed tightly against the slot 23 of the sleeve 14 under the action of the spring, providing a stable limiting effect. This design effectively prevents the rod 20 from sliding out or retracting on its own when no external force is applied, ensuring the stability and reliability of the portable dual-purpose infusion chair. Furthermore, the limiting mechanism effectively improves the connection stability between the rod 20 and the sleeve 14, ensuring the reliability of the portable dual-purpose infusion chair during the extension and retraction process. By providing appropriate resistance, the limiting mechanism allows medical staff to more easily control the extension and retraction of the rod 20, improving the convenience and comfort of operation. The limiting mechanism also effectively reduces friction and wear between the rod 20 and the sleeve 14, extending the service life of the portable dual-purpose infusion chair. Example 6

[0042] To meet the needs of patients of different heights, this application further designs an adjustable bed length mechanism. This mechanism utilizes a special structural design of the first frame 1 and the second frame 11, such as... Figure 5 As shown, the bed's physical length can be flexibly extended, effectively avoiding the problem of patients' heads or feet protruding from the bed due to insufficient bed length, ensuring the convenience and safety of medical staff during operation. The first frame 1 and the second frame 11 are both composed of a support tube 25 and an insertion tube 26. The support tube 25 serves as the main support structure of the bed, and one end of it is fitted with the insertion tube 26 to form a telescopic connection. This design allows the insertion tube 26 to slide freely within the support tube 25, thereby adjusting the length of the bed according to actual needs. To ensure the stability and reliability of the insertion tube 26 during the opening and closing process, the upper part of the support tube 25 has the same slots as the rod sleeve 14. These slots cooperate with the structure on the upper part of the insertion tube 26 to provide a basis for limiting operation. At the same time, the upper part of the insertion tube 26 is equipped with the same steel ball 24 and spring mechanism as the rod 20. Under the action of the spring, the steel ball 24 can be lifted and embedded in the slot of the support tube 25, thereby realizing the limiting operation of opening and closing the insertion tube 26.

[0043] When the bed length needs to be adjusted, medical staff only need to loosen the fixing device between the intubation tube 26 and the support tube 25 (such as locking screws or buckles, which are not detailed in this article but are standard technical methods), and then manually pull or push the intubation tube 26 to slide it within the support tube 25. Due to the action of the steel ball 24 and the spring mechanism, the intubation tube 26 will maintain a stable limit state during the sliding process and will not suddenly slide out or retract. After the intubation tube 26 is adjusted to the appropriate position, medical staff can use the fixing device to fasten the intubation tube 26 and the support tube 25 together. At this time, the steel ball 24 is pressed tightly against the groove of the support tube 25 under the action of the spring, providing a stable limit effect and ensuring the stability of the bed length. By adjusting the position of the intubation tube 26 within the support tube 25, the physical length of the bed can be flexibly extended to meet the needs of patients of different heights. In this way, the patient's head and feet can be completely placed within the bed, avoiding interference with the operation of medical staff and improving the efficiency and safety of medical work.

[0044] To facilitate the storage and operation of the handle 10 in the seated position, this application features an innovative design for the connection between the handle 10 and the round tube. Specifically, one end of the handle 10 is inserted into the round tube and connected to it via a bearing. This design allows the handle 10 to hang down naturally under its own weight, presenting a vertical arrangement, thus achieving convenient storage of the handle 10. One end of the handle 10 is designed to be inserted into the round tube and connected to it via a bearing. The choice of bearing ensures the smoothness and stability of the handle 10 during rotation, while also bearing the weight of the handle 10 itself. Since the handle 10 is connected to the round tube via a bearing, and one end of the handle 10 is inserted into the round tube, the handle 10 will hang down naturally under its own weight when no external force is applied, presenting a vertical arrangement. This design not only saves space but also makes the handle 10 more neat and aesthetically pleasing when stored.

[0045] When the handle 10 is needed, medical staff can simply lift it gently to adjust it to a suitable position for gripping. After use, simply release the handle 10, and it will naturally droop back to its stored state without any additional steps. The bearing connects the handle 10 and the round tube, reducing friction and wear between them, extending the service life of the handle 10 and the round tube, and improving the durability of the product.
