Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical and nursing device technology, specifically relating to a modular combination medical examination cart. Background Technology
[0002] In the current field of medical care, medical carts are indispensable mobile work units, widely used in ward rounds, physical examinations, and daily care. However, existing medical carts generally have limited functions, often designed as simple storage and transportation tools, making it difficult to meet the comprehensive needs of modern medical rounds that integrate multiple examination functions. When conducting rounds or bedside examinations, medical staff often need to carry multiple separate devices such as electrocardiogram monitors, blood pressure monitors, and thermometers, which not only increases preparation and storage time and reduces work efficiency but also makes operation in cramped and inconvenient in confined ward or bedside spaces.
[0003] For bedridden patients with limited mobility, weight measurement usually requires multiple people to move the patient to the weighing equipment, a process that is both labor-intensive and carries high safety risks. Furthermore, medical waste generated during physical examinations or nursing care is often disposed of directly in open waste bins. This waste may carry pathogens, and if not promptly and effectively sealed and sterilized, it can easily become a source of cross-contamination within the hospital. Summary of the Invention
[0004] To address the technical issues mentioned above, this invention proposes a modular medical examination cart that can integrate various medical examination equipment in a modular fashion to meet the needs of mobile medical examinations. The equipment can be quickly deployed during use and can also meet the weighing needs of bedridden patients, as well as the sterilization and collection of waste.
[0005] To achieve the above-mentioned technical objectives, the present invention is implemented through the following technical solution: A modular medical examination cart includes a main frame with a scissor lift frame installed inside. The scissor lift frame has casters at its bottom and is driven by an electric push rod to achieve lifting. A weighing plate is installed at the rear top of the main frame, and the weighing plate measures weight through an internal weighing sensor. One corner of the weighing plate is hinged to the main frame via a vertical rotating seat, allowing the weighing plate to rotate horizontally. An elliptical limiting hole is opened at the front top of the main frame, and a lifting plate is installed thereon. The bottom of the lifting plate is inserted into the limiting hole via a threaded sleeve. A drive screw is coaxially connected inside the threaded sleeve, and the other end of the drive screw extends downward and is coaxially connected to a drive motor. The drive motor controls the rotation of the drive screw, which raises or lowers the lifting plate. The main frame has openings on the left and right side walls at the front. Vertical round rods are symmetrically installed at the top left and right ends of the corresponding scissor-type lifting frame. Symmetrical movable frames are fitted onto these vertical round rods. Medical examination equipment can be installed inside the movable frames, allowing for quick deployment and storage of the equipment. The bottom surface of the movable frames is arc-shaped and has worm gear teeth along the arc. A horizontal worm is installed on the main frame, with both ends of the worm meshing with the worm gear teeth of the two movable frames. The threads at both ends of the worm are opposite, allowing the two movable frames to rotate simultaneously inward or outward when the worm rotates. A first bevel gear and a second bevel gear are coaxially installed on the drive screw and the worm, respectively. The first bevel gear and the second bevel gear mesh with each other, allowing the drive screw to drive the lifting plate to rise and fall while simultaneously rotating the movable frames. Multiple pull-out drawers are installed on the left rear side of the main frame; a waste bin is installed inside the right rear side of the main frame, with the top of the waste bin connected to the rear wall of the main frame, and a plastic bag opening is installed at the connection point. The inside of the plastic bag opening is covered with adhesive, which can be used to easily seal the waste bin during use and reduce the risk of pollution. The waste bin is equipped with sterilization lamps on its inner wall, which can sterilize medical waste; The lifting platform is equipped with a retractable table, which is convenient for storage and can increase the usable area. It can also be adjusted to accommodate the arm of a bedridden patient. Furthermore, a push-pull bracket is installed at the rear end of the main frame. The lower end of the push-pull bracket is hinged to the main frame, and the middle part is hinged to the main frame through a detachable connecting rod. It can be folded for storage and is convenient to use.
[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention achieves flexible and stable adjustment of the overall working platform height of the trolley by setting an internal scissor lift frame that can be driven by an electric push rod. This allows the trolley to be comfortable for medical personnel of different heights to operate, while the scissor lift frame can be completely folded and stored, significantly reducing the static space occupied by the trolley.
[0007] 2. By hinged to the main frame with a vertical rotating seat, the weighing plate can rotate horizontally, allowing it to extend and be pushed horizontally under the bedridden patient. Using its integrated weighing sensor, weight measurement can be completed safely and conveniently without moving the patient's body.
[0008] 3. Through the meshing transmission of the first and second bevel gears, the rotational motion of the drive screw is synchronously transmitted to the worm gear with reverse threads at both ends, thereby driving the two movable frames with worm gear teeth on the bottom surface to rotate synchronously in opposite directions, realizing the joint linkage control of the lifting plate's lifting and the movable frames' unfolding or retraction; and the lifting plate and its telescopic table can be adjusted to a suitable position for the bedridden patient's arm, facilitating operations such as blood pressure measurement; while providing a larger operating space, the movable frames on both sides automatically unfold outwards, quickly revealing the medical examination equipment inside for use, significantly improving space utilization efficiency.
[0009] 4. By installing an adhesive-lined plastic bag opening on the top of the waste bin, medical waste can be sealed immediately, effectively preventing contamination; and with the addition of sterilization lamps installed on the inner wall of the bin, the collected waste can be sterilized with ultraviolet light in real time or at set times.
