Description

Prone position prevents pressing sore pad

Technical Field

The invention relates to the technical field of medical instruments, in particular to a prone position pressure sore prevention pad.

Background

Patients with severe pulmonary infection have difficulty in expectoration and reduced oxygen saturation in vivo, and are usually prone to discharge phlegm under the action of body weight, so that infection can be controlled, and oxygen saturation can be improved.

Pressure sores are likely to occur on the body of the patient after lying in the prone position for a long time. The authorization notice number is: CN 212490507U, a patent named as a prone position anti-pressure sore turning-over pillow, provides a pillow which is convenient for assisting a patient to turn over without consuming a large amount of physical strength of the patient to prevent pressure sores. The publication number is: CN 111329692A, a patent of a prone position rehabilitation mattress provides a mattress which can prevent pressure sores and is convenient for sputum excretion in prone positions. The two patents are explored aiming at the aspect that the body is easily pressed to cause pressure sores when the patient in the prone position is in the long-time prone position, but the two patents only solve the unilateral problem of the patient in the prone position clinically, and the improved mattress and the improved pillow need to be matched for use during use, so that the patient can easily turn over, prevent the pressure sores and conveniently discharge phlegm.

Therefore, in order to solve the above technical problem, a new technical solution needs to be proposed to solve the problem. In particular to a prone position pressure sore prevention pad.

Disclosure of Invention

The invention provides a prone position pressure sore prevention pad, aiming at solving the technical problem that the existing prone position pressure sore prevention pad in the market does not have comprehensive effects of turning over, discharging phlegm and preventing pressure sore.

The following technical scheme is provided for achieving the purpose: a prone position pressure sore prevention pad comprises a supporting plate and a cushion pad arranged on the supporting plate, wherein an air cushion layer is arranged on the cushion pad and is a contact surface; still including the installation framework, the backup pad includes first backup pad and second backup pad, first backup pad and second backup pad interval set up and rotate and install installation on the installation framework, be equipped with drive unit in the installation framework, the drive unit makes first backup pad and/or second backup pad tilting rotate.

Preferably, the buffer pad and the cushion layer are respectively arranged above the first support plate and the second support plate, the buffer pad comprises a first buffer pad and a second buffer pad, and a gap space is reserved between the first buffer pad and the second buffer pad.

Preferably, the air cushion layer comprises an air cushion layer body and a plurality of air bag protrusions arranged on the air cushion layer body, the air bag protrusions and the air cushion layer body are in an integrated structure, and air bag grooves are formed among the air bag protrusions.

Preferably, the air bag bulges are arranged on the air cushion layer body in a scattered mode, so that the contact surface areas of the air bag bulges on the same straight line of the pressure sore prevention device are different.

Preferably, the air cushion layer and/or the buffer cushion are/is further provided with a headrest notch, and a headrest is detachably mounted in the headrest notch.

Preferably, the headrest comprises a pillow body, a first cushion body and a second cushion body, the first cushion body and the second cushion body extend upwards along the height direction of the pillow body, the first cushion body and the second cushion body are arranged at two ends of the pillow body, and the headrest is made of soft materials.

Preferably, the first cushion body and the pillow body are designed in an integrated mode, and the second cushion body is connected with the pillow body through a spring.

Preferably, the pillow body is provided with a mounting groove between the first cushion body and the second cushion body, a containing box is arranged in the mounting groove, and the height of the containing box is lower than that of the first cushion body and/or the second cushion body.

Preferably, the transmission unit comprises a driving shaft, a first transmission device and a second transmission device, and the first transmission device and the second transmission device are arranged on two sides of the driving shaft; when the driving shaft rotates forwards, the first transmission device is driven to move, so that the first supporting plate inclines upwards; when the driving shaft rotates reversely, the second transmission device is driven to move, so that the second supporting plate tilts upwards.

Preferably, the device also comprises a driving motor and a control chip, wherein the driving shaft is connected with an output shaft of the driving motor, and the control chip controls the movement of the driving motor;
