Description

Technical Field

[0001] This utility model relates to the field of pressure ulcer care technology, and in particular to a pressure ulcer recovery pad. Background Technology

[0002] Pressure ulcers are one of the most common complications in patients who require prolonged bed rest due to illness. They are mainly caused by local ulceration due to tissue ischemia and hypoxia resulting from prolonged pressure on a specific area of ​​the body. With the aging population and the rising incidence of cardiovascular diseases, the global incidence of pressure ulcers has also been increasing over the past decade.

[0003] Clinically, nurses usually turn patients every 2 hours to prevent pressure sores. However, traditional turning methods are time-consuming and laborious. Some patients also use air mattresses to reduce the probability of pressure sores. However, existing air mattresses cannot change the patient's lying position. If the patient lies flat on the air mattress for a long time and maintains the same position, it may cause discomfort such as soreness in some parts of the body. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned above, and to propose a pressure ulcer recovery pad.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pressure ulcer recovery pad, comprising a frame, an air bladder inside the frame, an air inlet pipe fixedly installed at one end of the air bladder, a valve fixedly installed on the outer wall surface of the air inlet pipe, a first breathable pad fixedly installed on the inner wall of the frame, a notch formed on one side surface of the first breathable pad, a rotating shaft rotatably connected between the inner walls of the two sides of the notch, a second breathable pad fixedly installed on the outer wall surface of the rotating shaft, an adjustment device provided on one side surface of the frame, the adjustment device comprising a transverse groove formed on one side surface of the frame, a sliding strip plate slidably connected inside the transverse groove, a rack fixedly installed on the surface of the sliding strip plate, and a gear fixedly installed on the outer wall surface of the rotating shaft, the rack and the gear meshing with each other. The gear drives the rotating shaft to rotate, and the rack drives the gear to rotate.

[0006] Preferably, a U-shaped plate is fixedly mounted on one side surface of the frame, and a threaded rod is rotatably connected between the inner walls of both ends of the U-shaped plate. A motor is fixedly mounted on one end face of the U-shaped plate, and the output end of the motor is fixedly connected to the threaded rod. The motor drives the threaded rod to rotate.

[0007] Preferably, the inner wall surface of the U-shaped plate has a groove, and a movable plate is threadedly connected to the surface of the threaded rod. A connecting rod is fixedly installed between the movable plate and the slide plate. The threaded rod enables the movable plate to move within the groove.

[0008] Preferably, a sealing device is provided on the surface of the frame away from the U-shaped plate. The sealing device includes a groove, which is formed on the surface of the frame away from the U-shaped plate. A long strip plate is slidably connected inside the groove. A rectangular plate is fixedly installed on the surface of the frame away from the U-shaped plate, and an electric telescopic rod is fixedly installed on the surface of the rectangular plate. The output end of the electric telescopic rod is fixedly connected to the long strip plate. The electric telescopic rod serves to move the long strip plate inside the groove.

[0009] Preferably, the surface of the elongated plate has a groove, and a slider is slidably connected inside the groove. An L-shaped rod is fixedly installed on the end of the slider away from the groove, and a sealing plate is fixedly installed on the end of the L-shaped rod away from the slider. The sealing plate effectively seals the air intake pipe.

[0010] Preferably, the elongated plate has a groove on its side, and a displacement plate is slidably connected inside the groove. The end of the displacement plate away from the groove is fixedly connected to a slider, and bolts are threaded onto the surface of the displacement plate. Multiple threaded holes are evenly distributed on the side of the elongated plate. The bolts and threaded holes effectively restrict the position of the displacement plate within the groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting an adjustment device, when the device needs to be used, first connect the external inflation device and the air inlet pipe. After the connection is completed, open the valve, start the external inflation device to inflate the airbag, and after inflation is complete, close the valve and disconnect the external inflation device and the air inlet pipe. Then, let the patient lie flat on the first and second breathable pads. The first and second breathable pads provide ventilation to the bottom of the patient's body, preventing pressure sores. During use, when it is necessary to adjust the patient's lying position, first start the motor. The movement of the threaded rod causes it to rotate, which in turn causes the movable plate to move inside the groove. This movement of the movable plate then causes the connecting rod to move, which in turn causes the slide plate to move inside the slide groove. This movement of the slide plate then causes the rack to move, which in turn meshes with the gear, causing the gear to rotate. This rotation of the gear then causes the rotating shaft to rotate, which in turn causes the second breathable pad to rotate. This rotation of the second breathable pad changes the patient's lying position. Through the coordination of the above structures, the device can change the patient's lying position during use, thereby improving the comfort of the device during use.

[0013] 2. In this utility model, by setting a sealing device, when the air intake pipe is not in use, the electric telescopic rod is first activated. The activation of the electric telescopic rod drives the long strip plate to move inside the slide groove. The movement of the long strip plate inside the slide groove eventually drives the sealing plate to move. When the position of the sealing plate is at the same horizontal line as the port of the air intake pipe, the electric telescopic rod is closed, and then the bolt is loosened and unscrewed from the threaded hole. The bolt and the threaded hole separate, causing the displacement plate to move inside the long groove. The movement of the displacement plate inside the long groove drives the slider to move inside the strip groove. The movement of the slider inside the strip groove drives the L-shaped rod to move. The movement of the L-shaped rod drives the sealing plate to move. The sealing plate moves so that it enters the interior of the air intake pipe to seal the air intake pipe. When the sealing plate has completed the sealing operation of the air intake pipe, the bolt can be screwed back into the corresponding threaded hole to fix the position of the displacement plate inside the long groove. Through the cooperation of the above structure, the air intake pipe can be sealed and blocked when not in use to prevent external dust from entering its interior. Attached Figure Description
