Description

Technical Field

[0001] The invention relates to the technical field of nursing beds, and in particular to an automatic nursing bed structure for patients with inconvenient limb movement. Background Art

[0002] At present, the nursing work of patients with limited limb mobility is more troublesome, and more and more patients need long-term bed rest treatment or rehabilitation. These long-term bedridden patients who have lost the ability to take care of themselves mainly rely on the care of hospitals, welfare institutions and families. They have difficulty turning over and getting up, and their eating and daily life all require care. For medical staff and patients' families, the daily care work of patients is very heavy. Therefore, nursing beds have appeared on the market. Nursing beds have become the main tool to help care for long-term bedridden patients. The demand for nursing beds is also increasing. Most of the existing electric nursing beds have basic functions such as lifting and lying down, and some nursing beds have functions such as turning over, which are mainly achieved by using foldable bed boards. For example, the Chinese invention patent with the authorization announcement number CN114732621A discloses a multifunctional electric nursing bed with a bedside table board, which includes a bed frame, a lifting device, a bed board assembly, a guardrail assembly, a turning mechanism, a back-lifting mechanism and a leg-bending mechanism. The nursing bed has the functions of turning over sideways, lifting backs and bending legs, and lifting. The guardrail is designed as a front and rear split guardrail, which can be stored independently. At the same time, the table board is integrated in the rear guardrail, and when the table board on the rear guardrail is used, it will not affect the patient's getting on and off the bed; and the table board has a forward and backward movement function, which can better adapt to the back-lifting sitting posture; however, this method of using a foldable bed board to achieve multifunctional assistance to patients has the following defects: When helping patients turn over, current nursing beds use a method where the side bed boards are folded inward to give the patients a push, but the folding position is single, the patients are not comfortable enough, and the folding position is easy to hurt the patients, which is not conducive to use.

[0029] Example 3: Please refer to Figure 1-14, which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When the present invention is used, the bed sheet 29 on the auxiliary mechanism 2 is in a relaxed state, covering the column bed structure 3. The patient lies on the bed sheet 29 on the surface of the bed structure 3. When turning over is required, the first L-shaped arm 24 and the second L-shaped arm 26 are lifted to a higher position, and then the two cloth rollers 27 rotate to tighten the bed sheet 29, so that the patient is lifted slightly away from the bed structure 3. Then, according to the direction of turning over, the two cloth rollers 27 rotate to the same side. The bed sheet 29 is displaced, so that the patient and the bed sheet 29 are rubbed, and the patient's body rolls naturally to turn over, and then the first L-shaped arm 24 and the second L-shaped arm 26 return to their positions, and rotate to loosen the bed sheet 29. When a bath is needed, the first L-shaped arm 24 and the second L-shaped arm 26 are lifted to the highest position, and the cloth roller 27 is used to tighten the bed sheet 29 so that the patient leaves the bed board structure 3. The patient is in a high position, and this position can also facilitate the nursing staff to massage the patient's back under the bed sheet 29. Then the sliding plate 415 slides outward. Then the lifting plate 416 is lifted, at this time, the simple bathtub 5 is pushed manually, the fixed slide bars 418 on both sides of the bottom support plate 417 are slid into the upper transverse groove 13, and the downward pressing plug block 419 is inserted into the positioning opening 14, and then the cloth roller 27 releases the bed sheet 29, so that the patient slowly falls into the simple bathtub 5, and the cloth roller 27 continues to rotate so that the bed sheet 29 is completely removed, and the bed sheet 29 is removed from the cloth roller 27, and the bed sheet 29 is carefully pulled out from under the patient's body, and then a bath can be taken; the present invention can assist the patient to turn over by using the auxiliary mechanism 2, and the patient can be taken out of the bathtub by using the auxiliary mechanism 2. The movement of the bed sheet 29 allows the patient to roll naturally to turn over. This turning method is different from the folding method. It adopts a soft turning method without a folding position, so that the patient can roll naturally, which is more comfortable and will not cause patient injury. The present invention uses the auxiliary mechanism 2 to lift the patient, and cooperates with the bathtub bracket structure 4 and the simple bathtub 5 to enable the patient to take a bath in bed, which is more convenient. In the present invention, the auxiliary mechanism 2 can be easily removed from the first bed frame 1 and the second bed frame 11, which is convenient for subsequent maintenance and repair work.

[0030] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial improvement of the present invention using this concept should be regarded as an infringement of the protection scope of the present invention.
