Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a wheelchair for nursing mental patients. Background Art
[0002] A wheelchair is a chair with wheels that can help replace walking. It is an important means of transportation for the wounded, sick, and disabled for home rehabilitation, turnover transportation, medical treatment, and outdoor activities. A wheelchair not only meets the transportation needs of the physically disabled and people with limited mobility, but more importantly, it makes it convenient for family members to move and care for the patients, allowing the patients to use the wheelchair for physical exercise and participate in social activities. There are many types of wheelchairs, and this type of multifunctional nursing wheelchair for psychiatric patients is one of them. It is a nursing wheelchair used for psychiatric patients.
[0003] However, existing wheelchairs for caring for mentally ill patients have the problem of poor comfort. When placing a mentally ill patient on a wheelchair, the patient is forced to maintain an upright sitting posture due to the lack of adjustment function of the backrest. This design defect seriously affects the patient's usage experience and makes it impossible for them to sit comfortably in the wheelchair. The lack of adjustment function of the backrest makes it impossible for the patient to adjust according to his or her needs and comfort, which may cause discomfort and fatigue during long-term use.

This personalized adjustment function can ensure that the patient's posture on the wheelchair is more ergonomic and reduce the discomfort caused by sitting for a long time.
[0032] Embodiment 2, as Figure 1-4 As shown, a hinge 2 is fixedly installed on the rear side of one of the two armrests 113, and a tray 201 is fixedly installed on the other end of the hinge 2. Tripods 204 are fixedly installed on both sides of the bottom of the wheelchair body 1, and sliding sleeves 205 are movably sleeved on the bottom surfaces of the two tripods 204. An upper buckle 203 is fixedly installed on the front bottom of the tray 201, and a lower buckle 202 is fixedly installed at the top center of the other of the two armrests 113. Bolts 207 are threadedly connected at the outer centers of the two sliding sleeves 205, and foot supports 206 are fixedly installed on the opposite sides of the two sliding sleeves 205.
[0033] In this embodiment, after the patient is placed on the wheelchair body 1, the tray 201 can be pushed forward to flip the tray 201 through the hinge 2, so that the tray 201 covers the armrest 113, and the tray 201 is pressed downward to engage the upper buckle 202 with the lower buckle 203, so as to fix the tray 201, and then the bolt 207 is reversed to make one end of the bolt 207 detach from the foot frame 204, and the sliding sleeve 205 is pushed upward to drive the foot support 206 to move synchronously, so that the foot support 206 is located at the bottom of the patient's foot, and when the height adjustment of the foot support 206 is completed, the patient can be put on the wheelchair body 113. The bolt 207 is turned so that one end of the bolt 207 is re-fitted to the tripod 204, thereby fixing the foot support 206. Moreover, through the structures such as the tray 201 and the foot support 206, not only can the wheelchair body 1 be used to restrict the patient, thereby preventing the psychiatric patient from leaving the wheelchair body 1 when the patient is on the wheelchair body 1, causing discomfort or danger, but the height of the wheelchair foot support 206 can also be adjusted. Such a design allows the wheelchair to adapt to the height and leg requirements of different patients, ensures that the support position of the foot is ergonomic, and further improves the patient's comfort.
[0034] Working principle: the staff first places the patient on the first bottom plate 103, and makes the patient's back side lean against the front side of the second bottom plate 105, and then pushes the gear 111 forward to make the connecting column 107 slide forward inside the connecting groove 106, and drive the slider 110 to slide forward on the inner surface of the slide groove 109, and at the same time drive the reset spring 108 to contract, so that the gear 111 is separated from the limit block 112, and then pull the second bottom plate 105 backward to drive the rotating rod 104 to rotate, so that the rotating rod 104 rotates while driving the connecting column 107 to rotate through the cooperation of the slider 110 and the slide groove 109, so that the gear 111 rotates synchronously, so that the second bottom plate 105 is tilted backward, and then the gear 111 is released to reset the reset spring 108. , the gear 111 is driven to move backward synchronously through the connecting column 107, so that the gear 111 is meshed with the limit block 112 again, thereby fixing the angle of the second base plate 105, and when the second base plate 105 is pulled backward, the telescopic column 114 is synchronously driven to extend. After the angle adjustment of the second base plate 105 is completed, the handlebar 102 can be pushed to drive the self-locking wheel 101 to rotate, thereby moving the wheelchair body 1, and through the rotating rod 104 and the gear 111 and other structures, the wheelchair body 1 can realize the angle adjustment of the second base plate 105, so that it can adapt to the needs and comfort requirements of different patients. This personalized adjustment function can ensure that the patient's posture on the wheelchair is more ergonomic and reduce the discomfort caused by sitting for a long time. When in use, after the patient is placed on the wheelchair body 1, the tray 201 can be pushed forward to make the tray 201 flip over through the hinge 2, so that the tray 201 covers the armrest 113, and the tray 201 is pressed down to make the upper buckle 202 and the lower buckle 203 engage, so as to fix the tray 201, and then the bolt 207 is reversed to make one end of the bolt 207 detach from the foot frame 204, and the sliding sleeve 205 is pushed upward to drive the foot support 206 to move synchronously, so that the foot support 206 is located at the bottom of the patient's foot, and when the height adjustment of the foot support 206 is completed, the patient can be put into the wheelchair body 112. The bolt 207 is turned so that one end of the bolt 207 is re-fitted to the tripod 204, thereby fixing the foot support 206. Moreover, through the structures such as the tray 201 and the foot support 206, not only can the wheelchair body 1 be used to restrict the patient, thereby preventing the psychiatric patient from leaving the wheelchair body 1 when the patient is on the wheelchair body 1, causing discomfort or danger, but the height of the wheelchair foot support 206 can also be adjusted. Such a design allows the wheelchair to adapt to the height and leg requirements of different patients, ensures that the support position of the foot is ergonomic, and further improves the patient's comfort.
