Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an anti-pressure sore nursing bed with convenient bed sheet replacement. Background Art

[0002] Pressure sores, also known as pressure ulcers and bedsores, are caused by long-term pressure on local tissues, resulting in continuous ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis. Pressure is the most important factor causing pressure sores. Bedridden patients maintain the same posture for a long time, and the sacrum, feet, elbows and other parts are continuously subjected to pressure from the body weight, local blood circulation is blocked, and local tissues are ischemic and hypoxic. After a certain period of time, pressure sores will occur. In addition, some bedridden patients may experience incontinence, excessive sweating, etc. The skin is in a moist state for a long time, the skin stratum corneum softens, the resistance is reduced, and bacteria and other microorganisms breed. , which increases the risk of pressure sores. Therefore, keeping the bed sheets clean and dry is an important way to reduce the risk of pressure sores in patients. The existing method of changing bed sheets is to transfer the patient to another place, change the bed sheets and then transfer them back to the nursing bed, or turn the patient over to lay the bed sheets. Both of these will increase the patient's discomfort and may cause secondary injuries. At the same time, it increases the work pressure of nursing staff. Bed sheets are prone to uneven laying, and the wrinkles on the bed sheets are more likely to cause pressure sores in patients. A pressure sore-proof nursing bed that is easy to change bed sheets is now used, which can provide a more convenient method of changing bed sheets and reduce the possibility of pressure sores. Summary of the invention

[0003] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0004] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide an anti-pressure sore nursing bed that is easy to change bed sheets, including a bed board, a plurality of bed legs fixed on the bed board, a turning mechanism arranged on the bed board, a mattress arranged on the turning mechanism, a sheet-making mechanism arranged on the bed board, two baffles fixed on both sides of the bed board, a support plate fixed under the bed board, and a control mechanism arranged on the support plate. The sheet-making mechanism includes two first rollers rotatably arranged at both ends of the bed board, two first motors respectively fixed at both ends of the bed board and used to drive the two first rollers to rotate, two second rollers rotatably arranged on both sides of the bed board, two first belts respectively wound around the two second rollers, a fixing component arranged on the two first belts, and a second motor fixed on the bed board and used to drive one of the second rollers to rotate; the two first belts are symmetrically arranged.

[0005] Specifically, the fixing assembly includes four limiting holes respectively arranged at both ends of the two first belts, and four rubber plugs movably arranged in the four limiting holes.

[0006] Specifically, the sheet-making mechanism further includes two rubber hoses respectively fixed on the two first rotating rollers, and two Velcro strips respectively fixed on the two rubber hoses.

[0007] Specifically, the turning mechanism includes a plurality of rotating plates rotatably arranged on the bed board, and a driving assembly arranged on the supporting plate for controlling the rotation of the plurality of rotating plates; two adjacent rotating plates can rotate relative to each other.

[0008] Specifically, the driving assembly includes a third motor fixed on the pallet, a U-shaped plate rotatably arranged on the pallet, circular rings rotatably arranged at both ends of the U-shaped plate, a steering plate rotatably arranged on the circular rings, a lifting plate fixed on the circular rings, and a fourth motor fixed on the pallet; the fourth motor is used to drive the steering plate to rotate.

[0009] Specifically, the lifting plate includes a support plate fixed on the circular ring, two electric telescopic rods respectively fixed at two ends of the support plate, and a support plate fixed at one end of the two electric telescopic rods.

[0010] Specifically, the control component includes a controller fixed on the support plate and a remote controller connected to the controller.

[0011] The beneficial effects of the present invention are:

[0012] (1) When it is necessary to change the bed sheet, first remove the rubber plugs on the two first belts, stick the two ends of the old bed sheet to the two Velcros respectively, then place the two corners of the new bed sheet on the side of the two first belts close to the caregiver respectively, and then fix the two corners of the new bed sheet with the rubber plugs respectively, start the two first motors, drive the two first rollers to rotate in opposite directions, and wrap the old bed sheet around the two first rollers until the old bed sheet drives the patient away from the mattress surface, and then start the second motor to drive the second roller connected to it to rotate, and the two first belts rotate, driving the new bed sheet to move away from the caregiver. Until the new sheet completely covers the mattress, then fix the other two corners of the new sheet on the two first belts. After the new sheet is laid, the two first motors are reversed, and the old sheet is put down together with the patient. Then, the patient is slightly turned over to take off the old sheet. Using the anti-pressure sore nursing bed with the above structure, the sheet can be replaced without transferring the patient. The operation is simple and convenient, which makes it convenient for nursing staff to change the sheet frequently, so that the patient's skin can always be in a dry and clean environment. The four corners of the new sheet are fixed and laid flat on the mattress. Wrinkles will not be generated due to the removal of the old sheet, further reducing the possibility of pressure sores.

[0013] (2) Bedridden patients need to turn over frequently to prevent the occurrence of pressure sores. The third motor is started to drive the U-shaped plate to rotate, and the circular ring rotates accordingly, driving the support plate to rotate. Taking the direction of the patient's head facing the second motor as an example, if the patient wants to turn over to the left, the circular ring drives the lifting plate to turn to the right side of the patient. The electric telescopic rod is adjusted to an appropriate length, and then the fourth motor is started to drive the steering plate to rotate upward. The circular ring rotates around its horizontal axis, the support plate rotates downward, and the support plate rotates upward, driving the rotating plate directly above the support plate to rotate, thereby helping the patient to turn over. When the patient needs to lift his upper body or legs, the same operation can be performed. In this way, the nursing staff does not need to turn over the patient, which reduces the work pressure of the nursing staff. Capable patients can control the remote control to complete independent turning over by themselves to prevent the occurrence of pressure sores. BRIEF DESCRIPTION OF THE DRAWINGS
