Description

Separate Walking Nursing Bed

technical field

The utility model relates to a nursing bed technology, specifically a separated walking aid nursing bed, and the international patent classification number is intended to be Int.Cl.A61G 7/00(2006.01)I.

technical background

After entering the 21st century, China's population structure is getting older. With the progress of the society and the continuous improvement of the quality of the population, some dysfunctional groups in the society - the elderly, the disabled, etc., have received more and more attention from the society. At present, the used nursing bed or living bed in the true sense for the family life of the handicapped has not yet appeared on the market. In view of the differences in the number of people using medical nursing beds and family living beds in terms of usage, usage and cost, only a few families use medical nursing beds instead of living beds. Nursing beds sold on the market are of a great variety, which can realize functions such as making the patient stand up, bend his legs and turn over. However, due to the limitations of its own design goals and positioning, the medical nursing bed has a relatively fixed application environment. There are many shortcomings and deficiencies in the use of the family mode, which increases the burden on the family and the difficulty of operation. Good walking aid facilities greatly restrict their movement, and they can only meet their living needs by docking the bed with the wheelchair, and the disabled generally cannot complete this docking method by themselves. The existing technology is roughly divided into two categories in solving the movement of the nursing bed: one is the integral mobile bed body, for example, the "multifunctional medical nursing bed" reported in Chinese patent application No. 02253340.0. Although this method has realized the conversion of bed and chair, one bed is multi-purpose, but because the bed body moves as a whole, the volume is huge, which brings inconvenience to the actual movement. The other is wheelchair mosaic type, for example, the "walkable multifunctional nursing bed" reported in Chinese patent application No. 200610019447.9. Although this design reduces the volume of the moving part, it is still a combination of a bed and a traditional wheelchair. The separated part still relies on the traditional wheelchair model, and the structure is complex and the manufacturing cost is high. The structural parts need to be removed in advance (such as the three boards at the end of the bed, etc.), which is inconvenient to use.

The separation process of the bed body (that is, the fixed bed surface part and the separation bed surface part) of the nursing bed of the present utility model, and the deformation process and principle of the separation bed surface part are as follows (see Figures 1-8):

When the user needs to leave the bed to move with walking aids, he must first control the nursing bed to lift his back. The working principle and process of the back lifting mechanism of the utility model is that the change in the axial dimension of the output shaft of the electric actuator 5 drives the connecting rod combination 4.2 in the four-bar mechanism to move, and the movement of the connecting rod combination 4.2 drives the first connecting rod connected to it. 4.1 and the second connecting rod 4.3 are driven. Since the connecting rod combination 4.2 itself is fixedly connected to the first bed board 1.1 on the fixed bed top part, the above-mentioned movement can drive the first bed board 1.1 on the fixed bed top part to move, and the second The movement of a bed board 1.1 respectively drives the left first flexible support board 1.2 and the right first flexible support board 1.2' to rotate around the left first connecting shaft 1.3 and the right first connecting shaft 1.3' respectively, so that the back can be lifted by folding the bed surface sports. The embodiment is designed to realize the maximum angle of raising the back (raise the back angle) to be 80°, and the minimum angle is 0°, that is, the bed surface is even and there is no raising the back (see Figures 2 and 6).

Secondly, it is necessary to control the nursing bed to realize the separation of the separated bed surface part and the fixed bed surface part. The working principle and process of the separation of the separated bed surface part and the fixed bed surface part in the utility model are as follows: after the back-raising process is realized, the movement of the back-raising mechanism and the fixed bed surface part together complete the back-raising action and lift the fourth The bed board 2.1, the second flexible support board 2.2 and the fifth bed board 2.4 are angle-fixed with the left first adjustable support rod 2.15 and the right first adjustable support rod 2.15' to form the required backrest angle (see Fig. 3, 5 ). At this time, the left first handrail 2.10, the right first handrail 2.10' and the left second handrail 2.11, the right second handrail 2.11' in the semicircle groove on the fifth bed board 2.4 and the seventh bed board 2.6 respectively can be used by the user of the bed. Or assist the nursing staff to manually stretch it out and fix it. The first left handrail 2.10 and the first right handrail 2.10' can not only play the role of auxiliary stretching and separation for the whole separation process, but also protect the user. The second flexible support plate 2.2 is designed on the part of the separation bed surface of the nursing bed of the utility model, which can enable the user to have better sitting posture and comfort, but this does not mean that the non-flexible support plate is not feasible (see Fig. 1 , 3-5).

The bed frame part of the utility model is a movable connection, including an integral support 3.3 with casters, a rotating connection shaft 3.2 and a movable support 3.1. When the separated bed surface part is relatively separated from the fixed bed surface part, the movable support 3.1 in the bed frame is opened by rotating the connecting shaft 3.2, and then folded by the self-contained rotating shaft 3.4 (see Fig. 3-5). After the above movement is completed, the fourth bed board 2.1 in the separated bed part and the first bed board 1.1 in the fixed bed part can slide and separate along the guide rail 1.7. The following process needs to be assisted by an auxiliary person: the auxiliary person can use the stretched left second handrail 2.11 and right second handrail 2.11' to carry out auxiliary sliding along the guide rail 1.7 to the separated bed surface part. The separated bed part slides along the guide rail 1.7 with the fixed bed part, until the lower part of the fifth bed board 2.4 in the separated bed part moves smoothly to the lower part of the left third bed board 1.6 and the right third bed board 1.6' in the fixed bed part , it is stopped by the auxiliary personnel. Then the sixth bed board 2.5 in the separated bed surface part is rotated downward relative to the fifth bed board 2.4 by the auxiliary personnel. After turning to an appropriate angle, use the left second adjustable support rod 2.16 and the right second adjustable support rod 2.16 'Fix the angle (see Figure 3-5). After the above movement is completed, the eighth bed board 2.7 in the separated bed surface portion is rotated and folded relative to the sixth bed board 2.5 along the fifth connecting shaft 2.13. In this transformation process, the utility model reserves space for the user's feet, which embodies the humanization of the design of the utility model. Then, the seventh bed board 2.6 in the separated bed surface part is rotated upward relative to the sixth bed board 2.5, and after turning to an appropriate angle, use the third left adjustable support bar 2.17 and the left third adjustable support bar 2.17' to adjust the angle fixed. After the above operations are completed, the transition from the separated bed surface to the walking chair mode can be realized (see Figure 3-5). At this time, the third left armrest 2.9 and the third right armrest 2.9' connected to the fourth bed board 2.1 can be turned up manually, and the auxiliary movement is controlled by the assistant, thereby realizing the complete separation of the separated bed surface part and the fixed bed surface part . Detach the bed surface part with the walker chair mode, rely on the 4 casters of the support frame 2.8 below it to realize auxiliary movement. The driving force for the movement of the walking aid comes from the promotion of the assistant, and its steering and braking control is also completed by the assistant, and the use method is the same as that of a conventional mobile seat.

The above-mentioned process is the specific deformation process and principle of the separated bed surface part and the fixed bed surface part of the nursing bed of the utility model to form a walking chair mode. Under the reverse auxiliary operation of the assistant, the separated bed surface part in the walking chair mode can be reset with the fixed bed surface part to restore the function of the nursing bed. The specific deformation process and principle are as follows: firstly, the auxiliary personnel retreats the separated bed surface part in the walking chair mode to the guide rail 1.7 in the fixed bed surface part; 2.9 and right third armrest 2.9', left third adjustable support bar 2.17 and left third adjustable support bar 2.17', seventh bed board 2.6, sixth bed board 2.5, eighth bed board 2.7, left second adjustable support bar 2.16 and the second right adjustable support rod 2.16', the movable bracket 3.1 in the bed frame part reversely moves back to the initial position; the third step, after the above-mentioned reverse movement, the separated bed part has been combined with the fixed bed part again, Return to the state that the back of the nursing bed is raised. At this time, the left first armrest 2.10 and the right first armrest 2.10', the left second armrest 2.11 and the right second armrest 2.11', the left first adjustable support rod 2.15 and the right The reverse movement of the first adjustable support rod 2.15' returns to the initial position. This step provides maximum security for the user. Finally, the nursing bed is controlled to complete the reverse movement of the back-lifting movement, so that the movable bed surface is restored to a horizontal position, and is closed with the fixed bed surface to form a flat nursing bed surface.

In addition, the working principle and process of the leg bending mechanism described in the utility model are (see Fig. 2, 7): the motor 7 (7') of the symmetrical structure (respectively) drives the gear pair 8 (8 ') to rotate, and the gear pair 8 (8') rotate (respectively) to drive the crank 9 (9') to move. The motion of crank 9 (9') can jack up the second connecting shaft 1.5 (1.5') whose other end is connected in the fixed bed surface part, thereby by means of the left and right second bed boards 1.4, 1.4' and the left and right second bed boards The folding of the three bed boards 1.6 and 1.6' realizes the user's leg bending movement. The leg bending mechanism of the utility model can control the angle (leg bending angle) of the leg bending motion by adjusting the position of the crank 9 (9'). The maximum bent leg angle of embodiment design is 30 °.

The nursing bed of the utility model is specially designed for the elderly, the disabled or other people with limited mobility in the society, and is positioned for use in family life (such as sunbathing, ventilating, going to the toilet and eating out of bed, etc.) (so it can also be called It is a separate walking aid living bed), which has the characteristics of simple structure, low cost, convenient use and functional use compared with medical nursing beds. But the utility model nursing bed does not rule out using as a medical nursing bed.
