Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical transport equipment. The device integrates pneumatic lifting and sitting-lying conversion, and is suitable for transporting patients in narrow spaces. Specifically, it is a pneumatic lifting and sitting-lying conversion patient transport bed vehicle. Background Art
[0002] Existing transfer equipment has the following defects: the publicly available transfer beds cannot adapt to the width and depth of home elevators, the lifting devices of multiple patents rely on electric drive and have no lifting structure, and traditional stretcher transfers require cooperation of multiple people and are prone to secondary injuries. Summary of the invention
[0003] A pneumatic lifting patient transfer bed vehicle for sitting or lying conversion, characterized in that it comprises: an aluminum alloy I-shaped vehicle frame (1) with eight universal wheels (2) symmetrically mounted at the bottom, a support (3) vertically mounted at the intersection of the I-shaped crossbar and having a built-in pneumatic rod (4), the top of the pneumatic rod being connected to a handrail (5) and a retractable soft rubber semi-cylinder (6) being embedded in the center, a horizontal U-shaped bed board (7) being arranged above the vehicle frame and being slidably connected to the vehicle frame through a slide groove (8), the U-shaped bed board opening facing forward and a circular turntable (9) being arranged in the middle, a front extension board (10) being detachably connected to the front of the bed board, and a rear extension board (11) being connected to the bed board through a buckle (12) and having two forms of an upright backrest and a horizontal bed board, and the outer cross bar of the I-shaped frame being designed as a sliding extension structure (13).
[0004] The innovative technical solution of the present invention: the I-shaped frame is equipped with 8 universal wheels to achieve 360° flexible movement; the pneumatic lifting mechanism lifts and transfers the patient through a telescopic soft-rubber column; the U-shaped bed board and the extension board are combined to form sitting / semi-reclining / lying modes, etc., which is suitable for 90cm narrow passages.

[0012] The frame of a pneumatic lifting and sitting-lying patient transfer bed is made of 6063-T5 aluminum alloy, covered with medical soft rubber, with an overall width of 88cm, a U-shaped bed board size of 72×60×60cm, and an extension board that can be extended to a maximum of 110cm. The pneumatic rod is made of SUS304 stainless steel cylinder, with a lifting speed of 3cm / s, a soft rubber semi-cylinder diameter of 6cm, and an extended length of 45cm. The surface of the backrest is covered with antibacterial PU material, and the buckle adopts a double insurance design of magnetic suction + mechanical lock.
[0013] The method of using this bed cart is: when it is necessary to transfer a patient lying on a hospital bed, first adjust the armrests and U-shaped bed board of the multifunctional bed cart to a height just equal to the bed surface, push the I-shaped bed frame to the bottom of the bed, and place the two sides of the pneumatic rod against the sides of the bed. The pointed ends of the two armrests are respectively facing the patient's lower waist and lower buttocks, and a semicircular column (the column is wrapped with a layer of soft rubber) is extended to support the waist and lower buttocks respectively. The height of the armrests is appropriately raised to lift the patient, and the U-shaped bed board is pushed to the patient's waist and buttocks, and the patient's upper body is lifted up to a semi-sitting position. The center stage supports the patient and rotates him 90 degrees. The rear extension bed board is installed at an appropriate height and angle, and the patient can sit on the bed cart in a sitting position by putting down his feet. The rear extension bed board can also be installed horizontally and the front extension bed board can be installed to allow the patient to lie flat on the bed cart, so that the patient can be transferred safely.
[0014] Innovation points: 1. The armrest can extend into a retractable semi-cylinder, which can lift the waist and hips under the action of the pneumatic rod, and can be easily inserted into the U-shaped bed board when raised to the level, making patient transfer effortless; 2. The patient can lie flat or sit on the bed, with a maximum width of 88cm, and can be used for transfer in narrow environments such as home elevators; 3. The patient can be converted into a lying stretcher with an overall height of 36cm and a fully folded height of 88X56X30cm, which can be used for emergency rescue in special environments such as ambulance transfer.
