Description

Nursing auxiliary turning device

technical field

The invention relates to the field of medical nursing equipment, in particular to an auxiliary turning device for nursing.

Background technique

Usually, there are three types of people lying in bed: supine, left side and right side. Because some limbs are always compressed when lying in bed, resulting in poor blood circulation or blockage in the compressed part. If the limb is compressed If the time is too long, the nerves will be numb and the quality of sleep will be affected, and the body will be necrotic in the oppressed area. In the long run, the function of the organs will be affected and the degeneration will be accelerated, which will lead to chronic diseases. Therefore, it is very necessary to turn over while in bed. Movements are easy for a healthy person, but for some patients with physical disabilities who cannot take care of themselves, turning over has become a very difficult thing.

Nowadays, nursing beds are commonly used in hospitals and home care. They are usually designed with a unique double-folded surface structure, and the bed surface adopts a special cushion structure, so that the bed surface can be adjusted to be flat or horizontal at will, with functions such as getting up and defecation. Some nursing beds on the market are also uniquely designed with physiotherapy magnetic pads, which play a role in health care, stimulate blood circulation, improve the level of nursing, and improve the patient's bed experience.

But the existing nursing beds have the following problems:

1. Regarding the nursing problem of dealing with defecation, the existing nursing bed structure is only to place a bedpan under the nursing bed. After defecation is completed, the bedpan is cleaned by the nursing staff. If the patient has frequent defecation, it will undoubtedly increase the workload of the nursing staff. Synchronization of sitting up and defecation cannot be achieved.

2. For some bedridden patients who cannot turn over, in order to prevent bedsores, the nursing staff need to help the patient to turn over frequently. Some existing nursing beds or bed boards designed as a whole need the nursing staff to move the patient's body to turn over. This method not only Nursing staff can also make patients feel uncomfortable.

Therefore, the present invention provides an auxiliary turning device for nursing to solve this problem.

Since the screw threaded sleeve 29 is limited by the fixing plate, at this time the screw threaded sleeve 29 will be in the first position. A vertical screw 27 slides up and down, while the screw threaded sleeve 29 lifts the sliding column 28 and the second link mechanism slides up and down, the upper end of the second link mechanism will be on the second front and rear flaps 7 and the first The bottom of a front and rear flap 8 slides back and forth against the second front and rear flaps 7 and the first front and rear flaps 8 to ascend or descend, and the second front and rear flaps 7 and the first front and rear flaps 8 lift the patient's back, which relieves the The pain of the patient in bed for a long time, the bottom of the upper bed body 1 is rotatably installed with a first right gear 22 located on the right side of the first left gear 13 and flush with the first left gear 13. The first vertical screw rod A second sprocket set is connected between 27 and the first right gear 22, the second sprocket set is composed of two second sprockets and a second chain, and one of the second sprockets is fixed and installed coaxially On the first right gear 22, another second sprocket is coaxially fixed on the upper end of the first vertical screw 27, and the two second sprockets are connected by a second chain. The rotation of the right gear 22 drives the first vertical screw 27 to rotate through the second sprocket group;

The lower surface of the upper bed 1 is rotatably mounted with a second rotating gear 14 located behind the first left gear 13 , and the bottom of the upper bed 1 is threadedly mounted between the first right gear 22 and the first left gear 13 . And the synchronous screw 23 meshing with the two at the same time, and the synchronous screw 23 is meshed with the second rotating gear 14, the synchronous screw 23 is provided with a hand crank, and the bottom of the upper bed 1 is rotated and installed with a The rotating screw 18 on the right side below the plate 17, the upper end of the rotating screw 18 is coaxially fixed with an opening and closing gear, and the upper end of the rotating screw 18 is engaged with an opening and closing mechanism located above the circular through hole. The opening and closing gear meshes with the opening and closing mechanism. When in use, the rotating screw 18 rotates with the opening and closing gear, and the opening and closing gear meshes with the opening and closing mechanism to rotate. The third sprocket wheel set 19 is connected, the third sprocket wheel set 19 is composed of two third sprocket wheels and a third chain, wherein one of the third sprocket wheels is coaxially fixed on the second rotating gear 14, Another third sprocket is coaxially and fixedly installed on the rotating screw rod 18, and the two third sprockets are connected by a third chain. 19 rotates with the rotating screw 18, the upper bed 1 is rotatably installed with a driven screw 44 located on the rear side of the rotating screw 18, and the rotating screw 18 and the driven screw 44 are connected with a A fourth sprocket set 45, the fourth sprocket set 45 is composed of two fourth sprockets and a fourth chain, wherein one of the fourth sprockets is coaxially fixed on the driven screw 44, and the other A fourth sprocket is coaxially fixed on the rotating screw 18, and the two fourth sprockets are connected by a fourth chain. When in use, the rotation of the rotating screw 18 is synchronized through the fourth sprocket group 45. With the driven screw 44 rotated, the lower end of the driven screw 44 is threadedly mounted with a lifting plate 20 on which a toilet 21 is placed under the circular through hole. In specific use, When the driven screw 44 rotates on the upper bed body 1, it rises or falls with the lifting plate 20 and the toilet 21;

The upper surfaces of the first left sliding plate 4, the second left sliding plate 5, the second front and rear flaps 7 and the first front and rear flaps 8 are provided with soft materials, such as sponge pads, etc., when the patient is lying on the bed for a long time. It can relieve the pain of the patient. A sponge plate is placed in the circular through hole opened by the square plate 17 to block the circular hole. When in use, the patient's legs are placed on the first left sliding plate 4 and the second sliding plate. The upper end of the two left sliding plates 5, the buttocks sit on the upper end of the circular through hole opened by the square plate 17, and the back lies on the upper end of the second front and rear flaps 7 and the first front and rear flaps 8;
