Description

Labor-saving transmission device for nursing bed

The present invention relates to a labor-saving transmission device for a nursing bed, and more particularly to a device that uses a labor-saving characteristic by a lever operation principle.

According to the aging of Taiwan's population, many elderly people's diseases have also increased, and many people with limited mobility, stroke, brain lesions, central nervous system damage and paralysis or long-term illness are lack of mobility. They must lie for a long time. In the nursing bed, the movement of the patient depends on the family and the nursing care to assist with the greater strength. It also causes inconvenience to the family, the care and the patient. In addition, the patient assists the family or the caregiver to solve the excrement or bath. The problem is that the patient feels deprived of dignity and gives the patient a great psychological burden.

1A and 1B, an "automatic care bed" disclosed in CN101912332A, comprising: a bed body 1, a back movable plate 131, an intermediate bed plate 132, a leg movable plate 133 disposed on the bed body, and a care hole 132a is disposed in the middle bed 132; in order to allow the patient to perform the defecation action directly on the hospital bed, the bottom of the back movable plate 131 and the leg movable plate 133 must be respectively provided with a driving member 131a, 133a, It is raised to the state shown in Fig. 1B. However, it is checked that the driving members 131a and 133a used in the conventional nursing bed are mostly the direct driving mode of the pneumatic cylinder, but the driving members 131a and 133a are disposed under the bed 1 to push the back movable plate 131 in a direct driving manner. And the leg movable plate 133 is very laborious, so the braking ability cannot be too small, so that not only power is consumed, but also the driving member 133a is attached to the bottom of the leg movable plate 133, so that the leg movable plate 133 can only be topped up. It is not able to settle down. Therefore, in the use form shown in Fig. 1B, when the patient excretes with the care hole 132a, the leg must be raised. In fact, the posture is not very appropriate and comfortable, and there is room for improvement. .

11 and 12 are perspective views and side views of one of the use states of the present invention, showing the use of the labor-saving transmission device 90 of the present invention for a care bed 100. A plurality of tripods 10A are mounted on the bottom of the bed frame body 10, a back pad body 20A is mounted on the back movable frame 20, and a movable pad body 30A is mounted on the leg movable frame 30, so that, for example, As shown in FIG. 12, a patient can be placed in a sitting position directly on the hospital bed to perform a defecation action, thereby reducing the burden on the patient and improving the convenience of the patient's bowel movement, and has the effect of self-care without the assistance of others. As for the defecation device (not shown) provided at the bottom of the bed frame body 10, the patent of the patent that is not the original creation has been patented separately, and therefore will not be described.

The main appeal of this creation lies in the technical features of the labor-saving transmission device 90. With the above-mentioned composition, the following effects are enhanced in use, and it is explained as follows:

First of all, in addition to the traditional bed or nursing bed, the creation screen is directly driven by the pneumatic cylinder. Because the back movable panel 131 and the leg movable panel 133 are pushed in a direct driving manner, it is very laborious and power-consuming, and the driving member 133a is It is disposed at the bottom of the leg flap 133, so that the leg flap 133 can only be lifted upwards and cannot be lowered downward. Therefore, in the use mode shown in FIG. 1B, when the patient excretes the care hole 132a, the leg is It must be lifted. In fact, this posture is not very appropriate and comfortable. In contrast, this creation system uses the lever operation principle to amplify the input force and give a large output force. The mechanical benefit of the lever is the ratio of the output force to the input force, so it has a "leverage" function. Therefore, the first hand crank handle 43 is only required to be rotated by the hand, that is, the first power output shaft 41 can drive the transmission mechanism 50, and the transmission mechanism 50 respectively drives the first push rod 60. And the second push-up lever 70, the first push-up lever 60 can drive the back movable frame 20 to be in a flat state or pick up an inclined angle; the second push-up lever 70 can synchronously drive the leg movable frame 30 flat state or downward settlement, this lever principle transmission mode has the use of labor-saving features to achieve use Convenient and energy-saving improvements.

Furthermore, the present invention can utilize the first clutch 46 of the control mechanism 40 to select the first hand crank handle 43 to be manually operated, or to drive the first power output shaft 41 by the motor 44 to drive the first clutch 46. Transmission mechanism 50. Therefore, this creation has the dual functions of both manual and electric operation.
