Description

Technical Field

[0001] The utility model belongs to the technical field of nursing equipment, and in particular relates to an auxiliary shifting device. Background Art

[0002] At present, the problem of population aging is gradually becoming a prominent social challenge. With the increase in average life expectancy and the decline in fertility rate, the proportion of the elderly population is increasing, which puts higher demands on the social medical care system, especially in the daily life care and medical care of the elderly. Helping the elderly get in and out of bed is a common and important nursing activity, but the traditional manual transfer method not only requires extremely high physical strength from the caregivers, but also easily causes injuries to the elderly. Therefore, the development of auxiliary transfer devices has become an effective way to solve this problem.

[0003] However, there are some common problems and shortcomings in the auxiliary shifting devices on the current market, which limit their effectiveness and popularity in practical applications. For example, a kind of elderly care auxiliary turning and transfer device with publication number CN113425521B, although it has the functions of assisting turning and lifting transfer, is large in size, occupies space, and is not very convenient to use in a narrow home environment. Secondly, the operational complexity of these devices is also a problem, and special training is required to use them correctly. The patient transfer device with publication number CN1024812224A, although easy to operate and can perform translational transfer of patients without changing the bed, but because the human body is heavy and the contact surface of the support plate of the device is large, in actual use, the support plate of the transfer device has a large resistance when inserted into the gap between the patient and the bed, or it is easy to bring the patient out again or cause the patient to roll when it is pulled out, which not only has poor comfort, but also has great safety risks.

[0004] In view of the above problems, it is urgent to design an auxiliary transfer device with small size, strong versatility, high comfort and good safety to improve the growing nursing needs. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The embodiment of the utility model provides an auxiliary displacement device, comprising a U-shaped insertion arm 1 and a body support plate 2, wherein the body support plate 2 is slidably mounted on the U-shaped insertion arm 1 through a linear motion mechanism 3, and can not only provide auxiliary support to the user's body during displacement, but also slide toward the side opposite to the opening direction of the U-shaped insertion arm 1 and slide out of the U-shaped insertion arm 1. Specifically:

[0030] like Figure 1 As shown, in this embodiment, the U-shaped arm 1 is welded by steel sections, and includes a longitudinal beam 102 and two cross beams 101. The two cross beams 101 are respectively vertically arranged at both ends of the longitudinal beam 102. The two cross beams 101 are parallel to each other and point in the same direction. The end of the cross beam 101 away from the longitudinal beam 102 serves as an insertion end 103. The insertion end 103 is provided with a chamfered surface and rounded corners to facilitate the U-shaped arm 1 to be inserted into the gap between the user and the bed to shovel the user.

[0031] like Figures 2 to 3 As shown, the linear motion mechanism 3 includes a support plate slide rail 301, a slide bar 302, a transmission screw 303, a reduction motor 304, and a screw nut 305. There are two support plate slide rails 301, which are arranged opposite to each other and fixedly mounted on the inner side walls of the two cross beams 101 respectively. There are two slide bars 302, which are fixedly mounted on the front and rear plate edges of the body support plate 2 respectively, and the two ends are respectively slidably matched with the two support plate slide rails 301. The reduction motor 304 is fixedly mounted on the longitudinal beam 102. The transmission screw 303 is connected to the output shaft of the reduction motor 304. The screw nut 305 is a threaded hole 3021 opened on the slide bar 302, and the threaded hole 3021 is threadedly matched with the transmission screw 303.

[0032] In addition, since the human body has a large mass, in order to prevent the body support plate 2 from sliding difficultly under the weight of the body, the support plate slide rail 301 is further provided with a first inclined rail 3011 extending obliquely upward on the side close to the insertion end 103, and the support plate slide rail 301 is provided with a second inclined rail 3012 on the side away from the insertion end 103, and the second inclined rail 3012 is at least partially parallel to the first inclined rail 3011. When the body support plate 2 is completely in the U-shaped insertion arm 1, the support surface of the body support plate 2 is at the same height as the upper surface of the U-shaped insertion arm 1; when the body support plate 2 needs to be moved to the outside of the U-shaped insertion arm 1, the two sliding bars 302 on the front and rear plate edges of the body support plate 2 will first slide obliquely downward along the first inclined rail 3011 and the second inclined rail 3012 respectively, so that the body support plate 2 drops a certain height, reduces the load borne by the body support plate, and ensures that the body support plate 2 can be moved out more smoothly. Correspondingly, a universal coupling 306 is further provided between the transmission screw 303 and the output shaft of the reduction motor 304 to ensure that the transmission screw 303 can rotate normally even when the output shaft of the reduction motor 304 is not coaxial, thereby better driving the body support plate 2 to move out from under the user.

[0033] like Figures 4 to 6 As shown, when the user needs to be displaced, the transmission screw 303 is driven to rotate forward by the reduction motor 304, which can drive the slide bar 302 to slide outward along the support rail 301, and transfer the body support plate 2 to the outside of the U-shaped arm 1 in advance, thereby reducing the friction between the nursing device and the user's body, and allowing the U-shaped arm 1 to be more smoothly inserted into the gap between the bed and the user's body, and then driving the reduction motor 304 to reverse, so that the body support plate 2 is located directly under the user's body, thereby increasing the effective support surface and improving the comfort and safety during the displacement process. After the auxiliary shifting device completes the shifting, for example: when the user is transferred from the nursing chair to the nursing bed by the auxiliary shifting device, similarly, the transmission screw 303 is driven to rotate forward by the reduction motor 304, and the body support plate 2 will first move diagonally downward by about 5 cm, so that most of the user's body weight is transferred to the U-shaped arm 1, reducing the friction resistance of the body support plate 2 to the outside of the U-shaped arm 1 along the direction parallel to the beam 101, and finally the U-shaped arm 1 is pulled out to complete the user's shifting, thereby avoiding taking the user out again when the auxiliary shifting device is recovered.

[0034] like Figure 2 and Figure 3As shown, as a preferred embodiment, a rolling support part 4 is also provided in parallel on the longitudinal beam 102, and the rolling support part 4 includes two upper and lower rows of rollers, and a certain gap is separated between the two rows of rollers so that the body pallet 2 can extend out of the gap. The rollers can not only provide auxiliary support for the body pallet 2 and reduce the load borne by the slide bar 302, but also convert most of the sliding friction between the slide bar 302 and the pallet slide rail 301 into rolling friction, thereby greatly reducing the wear between the slide bar 302 and the pallet slide rail 301.

[0035] Furthermore, a strip-shaped protrusion 201 parallel to the crossbeam 101 is integrally provided on the support surface of the body support plate 2 to reduce the friction resistance between the body support plate 2 and the user's body when the body support plate 2 slides.

[0036] The auxiliary shifting device improved by the utility model has a compact structure and strong versatility. It can not only scoop up the user more easily, but also can assist in supporting the user's body through the body support plate 2 when scooping up, greatly increasing the contact area between the shifting device and the user's body. By installing the device on a nursing bed, a nursing chair or other shifting platform for coordinated work, the transfer efficiency of the user, as well as the safety and comfort during the shifting process can be effectively improved.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
