During installation and disassembly, at least two medical staff are required to lift the base from both sides of the bed at the same time, which is inconvenient to operate and easily hurts the patient. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a multifunctional bedside chair for critically ill patients. The technical problem to be solved by the utility model is that the existing bedside functional chair is not convenient to disassemble and assemble.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A multifunctional chair for bedside of critically ill patients, comprising a chair back and armrests fixedly connected to the left and right sides of the chair back, characterized in that the functional chair also comprises a front support frame for being set on the ground, the front support frame is detachably connected to the two armrests and prevents the armrests from continuing to move upward relative to the front support frame, the two armrests are both positioned on the front support frame along the front-to-back direction, and the bottom of the front support frame is connected to a footboard for the patient to step on.

[0008] The chair back is used to be placed on the bed, and a front support frame is arranged on the ground so that the armrests can be positioned forward and backward only by being detachably connected to the front support frame. In this way, the patient's buttocks sit on the bed surface and his back can rest on the chair back. The front support frame is arranged in front of the patient to prevent the patient from leaning forward and falling to the ground. When the patient leans back on the chair back, the positioning pins on the armrests will tilt upward, and the armrests will be limited by the front support frame, making them stable to use. At the same time, a footboard is connected to the bottom of the front support frame, which can provide support for the patient's feet and improve comfort. At the same time, the entire front support frame is supported by the patient. The force exerted by stepping on the pedal can effectively prevent the front support frame from tipping over when the patient leans back on the chair due to insufficient weight, thereby ensuring stable and safe use. When assembly is required, the medical staff can push the front support frame to the side of the bed, and after the patient stands up and sits next to the bed, they can operate the chair back and forth to connect with the front support frame by themselves, and then let the patient lean back to rest. When disassembly is required, it is only necessary to separate the armrest from the front support frame on one side, and there is no need to operate on both sides of the bed at the same time to unlock it. The whole process can be achieved by the medical staff alone, which is convenient and labor-saving.

[0009] In the above-mentioned multifunctional bedside chair for critically ill patients, the left and right sides of the front support frame are provided with strip slide grooves arranged front and back, at least one end of the strip slide groove is through, and the inner wall of the strip slide groove is provided with a positioning groove open downward, and the two armrests are provided with positioning pins arranged in the left and right directions, and the two positioning pins are embedded in the positioning grooves through the strip slide grooves and are positioned on the front support frame along the front and back directions.

[0010] A strip slide extending forward and backward is arranged on the left and right sides of the front support frame, a positioning groove with an open side facing downward is arranged on the inner wall of the strip slide, and positioning pins are arranged on both armrests, so that the positioning pins can enter through the opening of the strip slide and be embedded in the positioning groove to achieve the front and rear locking of the chair back and the front support frame. In this way, when the patient leans back on the chair back, the positioning pins on the armrests will tilt upward, making it difficult for them to fall out of the positioning grooves and cause unlocking, and the use is stable; when the chair needs to be disassembled after use, the chair back can be pushed forward to control the positioning pins to fall out of the positioning grooves to smoothly unlock. During the disassembly and assembly process, the chair back does not need to be lifted on the bed surface to achieve unlocking, and the operation is convenient and labor-saving. As another solution, the positioning pins can be arranged on the support frame, and a strip slide is arranged on the inner side of the armrest, and a positioning groove with an open side facing upward is arranged on the inner wall of the lower side of the strip slide, so as to achieve the same convenient disassembly and assembly function in a similar locking manner.

[0011] In the above-mentioned multifunctional chair for critically ill patients beside the bed, the front support frame includes a support plate, a bracket and a support seat which are sequentially arranged up and down, the support plate is fixedly connected to the bracket, the bracket is connected to the support seat and can be adjusted up and down relative to the support seat, the bracket is locked with the support seat by a locking mechanism, and the strip slide is located on the support plate. The height position of the support plate can be adjusted by unlocking the locking mechanism, and then locked by the locking mechanism after the adjustment is completed. The locking mechanism can be an existing pin hole locking or bolt tightening locking mechanism, etc. In this way, after the combination is completed, the support plate can be operated to move down a certain distance, which is conducive to making the positioning pin and the positioning groove fit more closely, thereby reducing the probability of the positioning pin being disengaged and unlocked by external force during use, and when unlocking is required, the support plate can be raised again to complete convenient unlocking.

[0012] In the above multifunctional chair for critically ill patients, the open end of the strip slide is flared. Thus, when the positioning pin moves toward the front support frame and slides into the strip slide, the open end of the strip slide can provide a rough positioning and guiding effect, so that medical staff can more conveniently lock the chair back and the front support frame, thereby improving the convenience of installation and operation.

[0013] In the above multifunctional chair for critically ill patients, the end of the strip-shaped slide groove close to the chair back is an open end, and the opening direction of the positioning groove is inclined from top to bottom toward the side away from the chair back. In this way, the positioning pin needs to move in two completely opposite directions for a certain distance to be released from the strip-shaped slide groove, which is conducive to reducing the probability of the armrest and the front support frame being unlocked and disengaged during use.

[0014] In the above multifunctional chair for critically ill patients, there are multiple positioning slots arranged in sequence along the front-to-back direction, which is convenient for medical staff to fit the positioning pins into different positioning slots according to the different body shapes of patients, thus ensuring the comfort and applicability of the functional chair.

[0015] In the above multifunctional chair for critically ill patients, each armrest has at least two positioning pins arranged in a front-to-back spacing, and the two positioning pins can be simultaneously embedded in different positioning grooves. In this way, after multiple positioning pins are locked with different positioning grooves at the same time, the probability of the armrest rotating relative to the front support frame is reduced, making the use state of the chair back relative to the front support frame more stable and reliable.

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figure 1 , Figure 3 , Figure 4As shown, the multifunctional chair for critically ill patients next to the bed comprises a chair back 1 and armrests 2 fixedly connected to the left and right sides of the chair back 1. The chair back 1 can be an existing leather-wrapped seat back. The front support frame 3 is arranged on the ground. The left and right sides of the front support frame 3 are provided with front-to-back strip slide grooves 31. The strip slide groove 31 is at least one end through. The inner wall of the strip slide groove 31 is provided with a positioning groove 311 open downward. The two armrests 2 are provided with left and right direction positioning pins 4. The two positioning pins 4 can enter the strip slide groove 31 along the front-to-back direction and be embedded upward in the positioning groove 311 to lock the two armrests 2 and the front support frame 3 front-to-back. By setting a front support frame 3, the front support frame 3 is placed on the ground beside the bed to provide a certain counterweight, and strip slide grooves 31 extending forward and backward are set on the left and right sides of the front support frame 3, and positioning grooves 311 with an open opening facing downward are opened on the inner wall of the strip slide groove 31. The chair back 1 is placed on the bed, and positioning pins 4 are set on both armrests 2, so that the positioning pins 4 can enter through the opening of the strip slide groove 31 and be embedded in the positioning groove 311 to achieve the locking of the chair back 1 and the front support frame 3. In this way, the patient's buttocks sit on the bed surface and the back can rely on the chair back 1, while the front support frame 3 is arranged in front of the patient to prevent the chair back 1 from falling backward and prevent the patient from leaning forward and falling to the ground. When the patient leans back against the chair back 1, the positioning pin 4 on the armrest 2 will tilt upward, making it difficult for the armrest 2 to disengage from the positioning slot 311, resulting in unlocking, and the use is stable; when assembly is required, the medical staff can push the front support frame 3 to the bedside, and after the patient gets up and sits next to the bed, the medical staff can operate the chair back 1 to move forward and backward and lock it with the front support frame 3, and then let the patient rest on the backrest. When disassembly is required after use, the chair back 1 can be pushed forward to control the positioning pin 4 to disengage from the positioning slot 311 to unlock smoothly. During the disassembly and assembly process, the chair back 1 does not need to be lifted on the bed surface to achieve unlocking. The whole process can be achieved by the medical staff alone, which is convenient and labor-saving. Specifically, the front support frame 3 includes a support plate 32, a bracket 33 and a support seat 34 arranged in sequence from top to bottom. The support plate 32 is fixedly connected to the bracket 33. The bracket 33 is connected to the support seat 34 and can be adjusted up and down relative to the support seat 34. The bracket 33 is locked with the support seat 34 through a locking mechanism 35, and the strip slide 31 is located on the support plate 32. The height position of the support plate 32 can be adjusted by unlocking the locking mechanism 35, and locked by the locking mechanism 35 after the adjustment is completed. The locking mechanism 35 can be an existing structure. In this embodiment, the existing swing rod clamping structure is used to increase the sliding friction between the bracket 33 and the support seat 34 to achieve locking. In this way, after the combination is completed, the support plate 32 can be operated to move down a certain distance, which is conducive to making the positioning pin 4 and the positioning groove 311 fit more closely, thereby reducing the probability of the positioning pin 4 being released from the unlocking due to external force during use. When unlocking is required, the support plate 32 can be raised again to complete the convenient unlocking. Preferably, the open end of the strip slide 31 is flared. In this way, when the positioning pin 4 moves toward the front support frame 3 and slides into the strip slide 31, the open end of the strip slide 31 can provide a rough positioning and guiding effect, so that medical staff can more conveniently achieve the locking of the chair back 1 and the front support frame 3, and improve the convenience of installation operation.The end of the strip slide 31 close to the chair back 1 is an open end, and the open direction of the positioning groove 311 is inclined from top to bottom toward the side away from the chair back 1. In this way, the positioning pin 4 needs to move in two completely opposite directions for a certain distance to be unlocked in order to escape from the strip slide 31, which is conducive to reducing the probability of the armrest 2 and the front support frame 3 being unlocked and disengaged during use. Each strip slide 31 has eight positioning grooves 311 and is evenly spaced in the front and back directions. This is conducive to medical staff embedding the positioning pins 4 into different positioning grooves 311 according to the different body shapes of patients to achieve adaptation, ensuring the comfort and applicability of the functional chair. There are two positioning pins 4 on each armrest 2 and they are arranged at intervals in front and back, and the two positioning pins 4 can be embedded in different positioning grooves 311 at the same time. In this way, the two positioning pins 4 are locked with different positioning grooves 311 in the strip slide 31 at the same time, which is conducive to reducing the probability of the armrest 2 rotating relative to the front support frame 3, making the use state of the chair back 1 relative to the front support frame 3 more stable and reliable. As a further preference, the support plate 32 includes a plate body 321 and a strip metal piece 322 fixedly connected to the left and right sides of the plate body 321 by screws, and the strip slide 31 is located on the strip metal piece 322. In this way, the plate body 321 can use wooden pieces to improve the comfort of contact with the patient, and the strip metal piece 322 has higher strength and wear resistance, ensuring the stability of locking with the positioning pin 4. A footboard 6 for the patient to step on is integrally fixed to the support seat 34. The footboard 6 is horizontally arranged and has anti-slip texture on the surface of the footboard 6. In this way, the footboard 6 can provide support for the patient's feet and improve comfort. At the same time, the entire front support frame 3 is subjected to the force of the patient's downward stepping, which increases the counterweight of the front support frame 3 and avoids instability when the patient leans against the chair back 1.

[0031] like Figure 1-4 As shown, the bottom of the support seat 34 is connected with a lockable universal roller 5. In this way, when a certain front support frame 3 is needed, the universal roller 5 can be unlocked to achieve convenient movement, and then locked after moving to the bedside, which is convenient to operate. The lockable universal roller 5 is an existing component. The top of the chair back 1 is connected with a headrest 7 for the patient's head to lean against, and a safety belt 8 for restraining the patient is connected between the left and right sides of the chair back 1. In this way, the headrest 7 can provide support for the patient's head and neck to improve comfort. The safety belt 8 is an existing component similar to that used in car seats, which can better restrain the patient on the chair back 1, while ensuring the patient's activity space to avoid rapid forward falling and causing bumps and injuries, thereby improving safety and comfort. The outer side edge of the support seat 34 is also fixedly connected with a mounting boss 9, and the top surface of the mounting boss 9 has a vertically arranged positioning hole 91, and the outer side edge of the plate body 321 is fixedly connected with a positioning ring arranged coaxially with the positioning hole 91.

[0032] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
