Description

a nursing bed that can be placed in a sitting position

This creation relates to a care bed that can be placed in a sitting position, especially a device that uses a principle of leverage and has the use of labor-saving features.

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. .

Figure 11 is a perspective view of a state of use of the present invention, which can be provided with a dining tray 109 on the guardrail 108 without affecting the use of the present creation. As shown in FIG. 12, the patient is shown in a sitting posture. The present invention, by the above technical features, constitutes an action for the patient to directly sit on the hospital bed and perform defecation.

The present invention has the following effects, and its use has the following enhancements. It is explained as follows: First, the creation screen is driven by a pneumatic cylinder directly in addition to the traditional hospital bed or the nursing bed, because the direct driving method is used to push the back. The movable plate 131 and the leg movable plate 133 are very laborious and power-consuming, and the driving member 133a is fastened to the bottom of the leg movable plate 133, so that the leg movable plate 133 can only rise upward and cannot fall downward, therefore, In the mode of use shown in Fig. 1B, when the patient excretes with the care hole 132a, the leg must be raised, and in fact the 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 convenient use and energy saving.

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 both manual and electric The dual function of the operation.

Moreover, the present invention can utilize the second clutch device 54 of the transmission mechanism 50 to control the first transmission rod 51a and the second transmission rod 51b to be axially coupled or axially separated. That is, when the first power output shaft 41 drives the transmission mechanism 50, the present invention can select whether the second transmission rod 51b is to be synchronized with the first transmission rod 51a, that is, whether the leg movable frame 30 is to be The back movable frame 20 is linked together. Therefore, the creation can control the operating position of the transmission mechanism 50 according to the needs of the patient.

Therefore, the creation of the labor-saving transmission device is used in the nursing bed, has the labor-saving characteristics, achieves the convenience of use, saves energy and comfort, and then allows the patient to directly perform the defecation action in the sitting position on the bed. In order to reduce the burden on patients and improve the convenience of patients' bowel movements, they have the effect of self-care without the assistance of others.

In summary, the structure revealed by this creation is unprecedented, and it can achieve the improvement of efficacy, and it can be used for industrial utilization. It fully complies with the new patent requirements, and invites the bureau to grant patents to encourage innovation. There is no sense of morality.

However, the drawings and descriptions disclosed above are only preferred embodiments of the present invention, and modifications or equivalent changes made by those skilled in the art in accordance with the spirit of the present invention should still be included in the scope of the patent application.
