Description

Technical Field

[0001] The invention belongs to the technical field of health care, and in particular relates to a multifunctional care bed for paralyzed patients. Background Art

[0002] Current situation: Patients suffer injuries (such as cerebral hemorrhage and sequelae of cerebral stroke, hemiplegia or total paralysis, limb sprains or even fractures, etc.) that affect normal limb activities and require long-term bed rest. They eat, drink, defecate and urinate in bed. For patients, the inconvenience of movement causes their urine and feces to pollute the body and the environment, which can easily lead to secondary illnesses such as bedsores over time, causing great pain in nursing for their families. The patient's lack of sitting up, eating, washing hair and bathing, air pollution, spiritual life, etc. can easily lead to the patient's irritable temper and worse mental state. The mutual influence between bed rest, defecation, urination, and eating causes the patient to lose the sense of dignity of life and a significant decline in quality of life during bed rest.

[0003] It is very necessary for paralyzed patients to take a bath regularly. Since there are many inconveniences in bathing paralyzed patients, most nursing staff can only wipe the body instead of bathing, but this is far from meeting the basic needs of paralyzed patients for skin cleaning. Existing nursing beds usually only have the function of allowing patients to lie down or sit up. For the problem of bathing patients, it is necessary to move the patients away from the nursing beds and transfer them to the bathroom or bathroom for bathing; but the process of transferring paralyzed patients is relatively time-consuming and laborious, which not only brings great pain to paralyzed patients, but also increases the risk of accidental injury. At the same time, it also increases the workload of nursing staff, which is extremely inconvenient. Summary of the invention

[0070] Specifically, a multifunctional nursing bed for paralyzed patients also includes a smart TV 82. Patients who are bedridden for a long time and lack spiritual life not only easily lead to extreme loneliness in patients, but also have a great impact on their spiritual life. Long-term lack of spiritual life can also easily cause patients to be irritable, brain tissue atrophy and intelligence decline, and even slowly lose language function. In view of this, the above nursing bed is equipped with a smart TV 82, which can be connected to the Internet to watch news and TV series, and can be connected to the camera for video images. Older patients have hearing loss. In order to avoid the loud sound of the TV affecting others' rest, the TV external speakers 83 are set on both sides of the patient's head at the bedside of the bed, so that only the patient can hear the sound of the TV and will not affect others' rest.

[0071] The multifunctional nursing bed for paralyzed patients performs the following steps during operation:

[0072] S1, when the patient needs to take a bath, the first driving member 70 drives the first connecting rod 710 to rotate, drives the first synchronous pulley 730 to rotate, and drives the second synchronous pulley 731 to rotate through the synchronous belt 732, so that the third connecting rod 720 pushes the fourth connecting rod 721 to rise, and then drives the first folding plate 50 to move upward around the first turning axis 52 and fold to the outside of the bed frame 1. At the same time, the first connecting rod 710 drives the second folding plate 51 of the first folding part 5 and the second folding part 6 to translate a preset distance through the second connecting rod 711, and then moves downward around the second turning axis 53 and folds to the outside of the bed frame 1, so that the folding mechanism 3 is in a folded state;

[0073] S2, the first lifting member 210 drives the first lifting member 211 to a high position, so that the patient's head is switched from a lying state to a sitting state, and at the same time, the second lifting member 220 drives the second lifting member 221 to a low position, so that the patient's feet are switched from a lying state to a sitting state;

[0074] S3, the shower drive assembly 40 drives the first isolation cover 41 to rise to a preset height, so that the first isolation cover 41 switches to a working state, the first isolation cover 41 is located outside the support mechanism 2 and the patient, forming an isolation space for the patient to shower, and the first water spray assembly 42 sprays bathing water, and the patient takes a bath;

[0075] S4, after bathing is completed, the shower drive assembly 40 drives the first isolation cover 41 to descend to a preset height, so that the first isolation cover 41 switches to the accommodation state, and then the first drive member 70 drives the first connecting rod 710 to rotate, driving the first synchronous pulley 730 to rotate and driving the second synchronous pulley 731 to rotate through the synchronous belt 732, so that the third connecting rod 720 pushes the fourth connecting rod 721 to descend, and then drives the first folding plate 50 to fold downward around the first flip axis 52 and to the inner side of the bed frame 1. At the same time, the first connecting rod 710 drives the second folding plate 51 of the first folding part 5 and the second folding part 6 to fold upward and to the inner side of the bed frame 1 through the second connecting rod 711, and then translates toward the inner side of the bed frame 1 by a preset distance, so that the folding mechanism 3 is in a folded state.

[0076] When the patient finishes defecation: the second isolation cover 200 is adaptively covered on the abdomen of the patient in a lying state, the second water spray component 201 sprays cleaning water to the abdomen of the patient in a lying state, and the flushing component 203 sprays cleaning water to the patient's buttocks. After completion, the first air supply component 202a conveys hot air to the patient's abdomen after washing, so that the patient's abdomen after washing is quickly dried, and the second air supply component 202b conveys hot air to the patient's buttocks after washing, so that the patient's buttocks after washing are quickly dried. Finally, the waste water tank 204 collects the waste water in the toilet and the patient's shower.

[0077] It should be noted that:

[0078] 1. When the patient is lying down, the second isolation cover 200 is automatically vertically positioned on the abdomen. When the patient sits up, the patient's abdomen pushes the second isolation cover 200 forward.

[0079] 2. When the patient needs to leave the nursing bed, the nursing staff can flip the second isolation cover 200 from the outside of the bed to the inside of the bed to facilitate the patient to leave the nursing bed. When the patient returns to the nursing bed, the nursing staff flips the second isolation cover 200 back and covers the patient's abdomen again.
