Description

Nursing bed that is easy to get in and out of bed

Technical Field

The utility model relates to the technical field of nursing beds, in particular to a nursing bed which is convenient for getting in and out of bed.

Background Art

A nursing bed refers to a bedding used by patients with limited mobility.

For example, in the patent with the publication number CN112842733B, a "nursing bed that is convenient to get on and off" is disclosed. As shown in FIG1, the patent includes a nursing bed 1, a lifting mechanism 2 is provided at the lower part of both sides of the nursing bed 1, a rotating mechanism 3 is provided inside the nursing bed 1, an adjusting mechanism 4 is provided at the upper part of the rotating mechanism 3, and a mattress 5 is provided at the upper part of the adjusting mechanism 4. The lifting mechanism 2 is used to adjust the height of the nursing bed 1, the rotating mechanism 3 is used to drive the adjusting mechanism 4 to rotate horizontally, and the adjusting mechanism 4 is used to adjust the posture of the mattress 5.

When the patient gets out of bed, the adjusting mechanism 4 is first used to adjust the patient on the mattress 5 from a supine position to a state in which the back and buttocks are raised; then the adjusting mechanism 4 is horizontally rotated by the rotating mechanism 3 to allow the patient to face one side of the nursing bed 1; then the adjusting mechanism 4 is used to straighten the back of the patient on the mattress 5 and flatten the buttocks, so that the patient's legs naturally hang down on one side of the nursing bed 1; then the lifting mechanism 2 is used to lower the height of the nursing bed 1 to facilitate the patient to get out of bed.

The lower end of the lifting rod 323 is fixed to the rotating seat 32 by screws or bolts. The upper portion of the turning seat 322 is hinged to one end of the bottom surface of the support plate 41. The upper end of the lifting rod 323 abuts against the bottom surface of the support plate 41, and the upper end of the lifting rod 323 can slide on the bottom surface of the support plate 41.

Case (1), when the patient lies flat on the mattress: the patient's back is located on the back pad 51, the patient's buttocks and thighs are located on the buttocks pad 52, and the patient's calves and feet are located on the extension pad 53.

Situation (2), when the patient gets out of bed:

① Extend the back-lifting telescopic rod 43 and the hip-lifting telescopic rod 45.

After the back-lifting telescopic rod 43 is extended, the back-lifting telescopic rod 43 pushes the back-lifting frame 42, the back-lifting frame 42 rotates clockwise and is lifted, and the back-lifting frame 42 pushes the back cushion 51, the back cushion 51 rotates clockwise and is lifted, so that the patient's back can be lifted.

After the hip-lifting telescopic rod 45 is extended, the hip-lifting telescopic rod 45 pushes the hip-lifting frame 44, and the hip-lifting frame 44 rotates counterclockwise and lifts up. The hip-lifting frame 44 pushes the hip pad 52, and the hip pad 52 rotates counterclockwise and lifts up, so that the patient's hips and thighs can be lifted.

When the hip pad 52 is lifted, the extension pad 53 rotates downward under its own weight, so that the patient's lower leg droops naturally.

When the back-lifting frame 42 pushes the back pad 51, because the limit pin 421 on the back-lifting frame 42 is located in the limit hole 512 on the bottom surface of the back pad 51, when the angle between the back pad 51 and the support plate 41 is greater than or equal to 90°, the back pad 51 can be prevented from continuing to rotate clockwise under the action of its own weight, thereby preventing the back-lifting frame 42 from separating from the back pad 51 and preventing the back pad 51 from hitting the patient, thereby improving safety.

② Start the driving motor 33, the driving motor 33 drives the driving gear 34 to rotate, the driving gear 34 drives the driven gear 35 to rotate, the driven gear 35 drives the adjustment mechanism to rotate, and the adjustment mechanism drives the mattress to rotate. When the adjustment mechanism rotates horizontally by 90°, the patient faces the width direction of the nursing bed 1.

③ Continue to extend the back-lifting telescopic rod 43 to make the patient's back stand upright, and retract the hip-lifting telescopic rod 45, and the hip-lifting frame 44 rotates clockwise under the action of its own weight and the patient's weight until the patient's buttocks are flat, and the patient is in a sitting position.

④ Extend the lifting rod 323, the upper end of the lifting rod 323 pushes the support plate 41 upward, and the support plate 41 rotates clockwise with the hinge of the support plate 41 and the flip seat 322 as the rotation center, so that the patient sitting on the mattress is in a standing posture. At this time, the patient does not need to stand up directly from a sitting position when getting out of bed, which reduces the range of motion. For elderly patients with weak strength, it reduces the difficulty of getting up; for patients with cardiovascular and cerebrovascular diseases, it reduces the risk of cerebral ischemia. Thus, the convenience and safety of getting out of bed are improved.

Case (3), when the patient is in bed: reverse the steps in case (2).

As can be seen from the above description, by setting the turning seat 322 and the lifting rod 323 on the rotating seat 32 in the rotating mechanism, the support plate 41 in the adjusting mechanism is hinged with the turning seat 322, and the support plate 41 is slidably abutted against the upper end of the lifting rod 323, so that the angle of the support plate 41 can be adjusted. When the support plate 41 is lifted, the patient on the mattress can change from a sitting position to a position tending to stand, which is conducive to reducing the range of movement changes between the sitting position and the standing position of the patient, and is conducive to improving the convenience and safety of getting in and out of bed.

Further, as shown in Fig. 6-Fig. 7, a sliding pin 3231 is welded and fixed to the upper end of the lifting rod 323, and a sliding rail 411 is welded and fixed to the bottom surface of the support plate 41, and the sliding rail 411 is provided with a sliding hole 412 for cooperating with the sliding pin 3231. In the process of the lifting rod 323 gradually lifting the support plate 41, the sliding pin 3231 slides in the sliding hole 412, and the sliding hole 412 limits the sliding range of the sliding pin 3231, and also prevents the sliding pin 3231 and the sliding hole 412 from separating, thereby preventing the lifting rod 323 from separating from the support plate 41, and improving the reliability of use.

Further, as shown in Fig. 4 to Fig. 7, a supporting seat 324 is welded and fixed to the upper part of the rotating seat 32, a lifting rod 323 is provided between the supporting seat 324 and the flip seat 322, and the bottom surface of the support plate 41 abuts against the supporting seat 324. When the supporting seat 324 is not provided, if the support plate 41 is in a horizontal state, the support plate 41 is supported by the lifting rod 323 and the flip seat 322; the provision of the supporting seat 324 can support the support plate 41 in a horizontal state together with the lifting rod 323 and the flip seat 322, which is conducive to improving the stability and reliability of the horizontal state of the support plate 41.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
