An intelligent trolley used in medical clinic

Abstract

The invention discloses an intelligent medical clinical cart, which comprises a cart body and an automatic leveling component. The cart body comprises a chassis which is provided with front wheels andrear wheels, and rear wheel supports are fixed to the chassis. The automatic leveling component comprises electric push rods, a first mercury switch, a second mercury switch, a first battery and a second battery. The electric push rods are mounted on the front portion of the chassis, output shafts of the electric push rods are fixedly connected with corresponding rear wheel supports, and the first mercury switch and the second mercury switch are horizontally mounted in the chassis. Two fixing electrodes of the first mercury switch face forwards, and two fixing electrodes of the second mercuryswitch face backwards; the first battery, the first mercury switch and the electric push rods are sequentially and serially connected to form a first circuit; the second battery, the second mercury switch and the electric push rods are sequentially and serially connected to form a second circuit; current directions of the first circuit and the second circuit are opposite. The cart can be kept leveled automatically no matter the cart passes through a slope or a horizontal plane.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intelligent cart used in medical clinics. Background technique [0002] Medical tray carts are mainly used to transfer medical supplies such as medical equipment, instruments, and medicine bottles, which can greatly reduce the burden on caregivers. It is widely used, whether it is in large hospitals or small clinics. [0003] When the medical pallet trolley passes the slope, the trolley will tilt with the slope. If the angle of inclination is too large, the medical supplies on the trolley will easily slip, and may even slip out of the trolley and fall to the ground, especially Containers containing liquids, tilting the cart may also cause liquids to spill. [0004] Chinese Utility Model Patent Specification CN107854256A discloses a trolley for medical care. The trolley is provided with a liquid storage compartment, which is connected to the trolley in rotation. The li...

Problems solved by technology

[0003] When the medical pallet trolley passes the slope, the trolley will tilt with the slope. If the angle of inclination is too large, the medical supplies on the trolley will easily slip, and may even slip out of the trolley and fall to the ground, especially Containers with liquids, the cart may be tilted and the liquid may be spilled

[0004] Chinese Utility Model Patent Specification CN107854256A discloses a trolley for medical care. The trolley is provided with a liquid storage compartment, which is connected to the trolley in rotation. The liquid storage compartment can be kept vertical under the gravity of the metal block. , the trolley can only keep the liquid storage compartment tilted, while other parts will also tilt, and in the process of going up and downhill, you need to manually release the constraints of the liquid storage compartment, which is troublesome to use. After the liquid storage compartment is released, it is easy to cause The swing of the liquid storage compartment is also easy to cause the liquid to spill

[0005] In addition, many medical tray carts are equipped with shock absorbing devices to reduce the vibration of the cart and prevent damage to the medical equipment on the cart. The shock absorbing devices of the existing medical tray carts generally use springs to absorb Shock structure (such as Chinese utility model patents CN204458975U, CN204379450U, etc.), it can only eliminate the vibration in the vertical direction, the vibration in the horizontal direction cannot be eliminated, the effect of shock absorption is relatively poor, and the stability of the structure is relatively poor. When the car is hit, the amplitude of the spring vibration will be relatively large, which will cause damage to medical supplies
