Description

Nursing bed capable of sitting in bed

The present invention relates to a nursing bed capable of sitting in bed, and in particular to a device that uses the principle of lever operation and has labor-saving features.

According to the aging of Taiwan's population, many elderly diseases have also increased, and many people with reduced mobility, stroke, brain disease, central nervous system damage, paralysis or prolonged illness in bed lack mobility and must lie for a long time. In the nursing bed, the patient's movement needs to rely on family members and caregivers to assist them with greater force. It also causes inconvenience to family members, caregivers and patients. In addition, patients in the family members or caregivers assist in solving excreta or bathing Problems make patients feel dignified and place a huge psychological burden on patients.

As shown in Figs. 1A and 1B, it is an "automatic nursing bed" disclosed by CN101912332A, which includes: a bed body 1, a back movable plate 131, a middle bed plate 132, and a leg movable plate 133 provided on the bed body, and A nursing hole 132a is provided in the middle bed plate 132; in order to allow the patient to perform defecation directly on the bed, the bottom of the back movable plate 131 and the leg movable plate 133 must be respectively provided with driving members 131a, 133a, It rises to the state shown in FIG. 1B. However, most of the driving parts 131a and 133a used in conventional nursing beds are directly driven by pneumatic cylinders. However, such driving parts 131a and 133a are located under the bed 1 and push the back movable plate 131 directly.

FIG. 11 is a reference perspective view of a use state of the present invention. A dining plate 109 can be installed on the guardrail 108 without affecting the use of the present invention. FIG. 12 is a schematic diagram showing a patient in a sitting position. The present invention uses the above technical features to form a posture in which the patient can sit directly on a hospital bed to perform defecation.

With the above structure, the present invention has the following functions and enhancements in use, which will be described later:

First of all, the traditional screen or nursing bed for removing the screen in the present invention is directly driven by a pneumatic cylinder, because the back movable plate 131 and the leg movable plate 133 are pushed by the direct driving method, which is very labor-intensive and consumes power. It is set at the bottom of the leg movable plate 133, so that the leg movable plate 133 can only be lifted upwards and cannot settle downwards. Therefore, when the patient uses the care hole 132a for excretion, the legs shown in FIG. You must lift up. In fact, this posture is not very appropriate and comfortable. In contrast, the present invention utilizes the principle of lever operation, which can amplify the input force and give a larger 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 present invention only needs to turn the first manual drive handle 43 by hand, that is, the first power output shaft 41 can be used to drive the transmission mechanism 50, and the transmission mechanism 50 drives the first push-up lever 60 respectively. 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 raise an inclined angle; the second push-up lever 70 can synchronously drive the leg movable frame 30 Flat state or downward settling, this lever-based transmission method has the characteristics of labor-saving, so as to achieve convenience and energy saving.

Furthermore, the present invention may use the first clutch 46 of the control mechanism 40 to select whether to manually operate the first manual drive handle 43 or to use the motor 44 to drive the first power output shaft 41 to drive the first Transmission mechanism 50. Therefore, the present invention has the dual function of both manual and electric operation.

In addition, in the present invention, the second clutch device 54 of the transmission mechanism 50 can be used to control the first transmission rod 51a and the second transmission rod 51b to be axially coupled or to be separated from each other. 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 connected with The back movable racks 20 are linked together. Therefore, the present invention can control the operating position of the transmission mechanism 50 according to the needs of the patient.

Therefore, the labor-saving transmission device disclosed in the present invention is used in a nursing bed, which has the characteristics of labor-saving, and achieves convenience in use, saves energy and comfort, and further enables patients to perform defecation directly on the bed in a sitting position. In order to reduce the burden on patients and improve the convenience of defecation, it has the effect of achieving self-care without the assistance of others.

In summary, the technical means disclosed in the present invention do have invention patent elements such as "newness", "progressivity" and "available for industrial use". A sense of virtue.

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