Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a multifunctional portable trolley for stomatology. Background Art

[0002] During clinical treatment in the dental department, the assistant's four-handed operation is often required. The assistant's position often uses a cart to place common dental materials and instruments and equipment. However, the currently used dental carts have problems such as disordered placement of items and incomplete operation functions. Therefore, there is a need for a portable cart that has both reasonable storage functions and comprehensive functions for the assistant's position during clinical four-handed operation in the dental department.

[0003] There are two types of dental treatment carts currently used in clinical practice: 1. Mobile side cabinets for dental storage, the table top is made of wooden board or tempered glass, the cabinet body is made of wooden board or high-quality stainless steel, the drawers are 4-5 layers, and there is no socket. This type of cart design is prone to being too heavy as a whole and cannot be moved lightly; multiple instruments and equipment are taken back and forth, which is not convenient for equipment management, and the external charging power cords are tangled in a mess; the fixed operating height is not ergonomic. 2. Mobile side cabinets for dental medical equipment, the table top and the cabinet body are made of wooden boards, the drawers are 1-2 layers, there is a large distance between the drawers, the interval is an operating platform, and it comes with several sockets. This type of cart design is prone to shrinking storage space, and it is impossible to classify and store various types of dental materials and instruments, which increases the trajectory of assistants taking the required items back and forth. The above two types of dental treatment carts have the disadvantages of lacking garbage classification and instrument pretreatment storage devices, and a single storage space. At the same time, they are not equipped with an infusion device for emergency treatment, which invisibly increases the workload of assistants when they cooperate with four hands.

[0004] Patent publication number CN210749623U discloses a four-hand operation platform for oral diagnosis and treatment, including a platform box and a storage rack. The storage rack is installed on the platform surface of the platform box, and movable universal wheels are installed at the four corners of the bottom of the platform box; the storage rack is provided with a first storage compartment, a second storage compartment, and a third storage compartment, and the platform box is provided with multiple drawers, and a charging device is provided at the rear side of the platform box. However, the four-hand operation table cannot realize the lifting function, and the fixed operating height is not ergonomic; and the drawers are all ordinary pull-out drawers, and the efficiency of taking items is slow.

[0005] In order to better serve the clinic, it is necessary to design a multifunctional portable cart for the assistant to use during the clinical four-hand operation in the dental department to improve work efficiency, shorten treatment time, improve the satisfaction of medical staff and patients, and reduce the risk of infection.
