Description

A medical transport trolley

technical field

The utility model relates to the technical field of medical equipment, in particular to a medical transport trolley.

Background technique

Medical equipment refers to instruments, equipment, utensils, materials or other items used alone or in combination for the human body, including the required software. Medical equipment is the most basic element of medical treatment, scientific research, teaching, institutions, and clinical disciplines, including professional medical equipment and household medical equipment.

The workers in the hospital often use transport carts in their daily work to facilitate the transportation of blood samples, various reports, films and other items. The carts used now are all modified by the workers themselves. The frame does not have the function of lifting. When collecting blood samples, the worker needs to bend down to pour the blood sample, which is labor-intensive; at the same time, the worker does not bend down when collecting the blood sample, but directly pours it in from a high place, and the blood sample will directly impact and cause damage to the sample, and it is easy to Hemolytic reactions, etc., affect the results of subsequent tests, thereby affecting the diagnosis, or causing patients to need to re-draw blood tests, adding additional pain to patients. The existing trolley also has the disadvantage of being unable to transport blood samples and other items upstairs when the elevator is out of service, and the problem of occupying too much space.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a medical transport trolley, which has the feature that the frame can be lifted.

In order to achieve the above object, the utility model provides the following technical solutions:

A medical transport trolley, comprising a frame body, an L-shaped frame, handles, and wheels, the frame body is slidably connected to the frame along the vertical direction, and the handles are provided on both sides of the top of the frame , the wheels are arranged at the bottom of the frame, the frame is rotatably connected with a vertical screw, the bottom of the frame is connected with a sliding block threaded with the screw, and the frame is vertically A chute for sliding of the sliding block is provided.

By adopting the above technical solution, the frame of the medical trolley can place items to be transported, the wheels of the medical trolley can realize the transport function of the medical trolley, the handle is set to facilitate the user's operation, and the medical transport trolley can be realized by screw drive. Lifting and lowering reduces the user's bending and saves effort. At the same time, the screw drive also has the feature of self-locking, which avoids the sliding of the frame after it is raised, and is relatively safe and reliable. At the same time, the handle is provided for easy pushing and pulling, improving transportation efficiency.

Further, the vehicle frame is also connected with guide rods arranged vertically and located on both sides of the screw, and the bottom of the frame body is also provided with guide blocks that cooperate with the guide rods.

By adopting the above technical solution, setting the guide mechanism can guide the frame body to move up and down along the vertical direction, reduce the influence of left and right side tilt, and facilitate the operation.

Further, the wheels include a set of driven wheels and a set of stair climbing wheels, the stair climbing wheels are arranged at the bottom of the frame near the handle, the stair climbing wheels include a transmission main shaft, a three-arm support and a crawling wheel, the transmission main shaft is arranged at the bottom of both sides of the vehicle frame, the three-arm support is rotatably connected with the transmission main shaft, and the crawling wheel is rotatably arranged at a position where the three-arm support is away from the transmission main shaft Ends.

By adopting the above-mentioned technical solution, when moving on flat ground, the three-arm support does not rotate, and two of the three crawling wheels on the three-arm support move on the ground. When climbing stairs, the user pushes or pulls the vehicle frame, and the crawling wheel encounters the resistance of the stairs, and the resistance of the stairs makes the three-arm support rotate around the transmission shaft, thereby climbing up and down a step to complete the stairs.

Further, the frame body includes a rear panel connected to the sliding block, a foldable side panel adjacent to the rear panel, a front panel and a bottom panel, and the side panel includes a a rear side panel and a front side panel hinged to the sides of the front panel, the rear side panel is hinged to the front side panel, the bottom panel is hinged to the bottom of the front panel, and the front panel is close to the rear panel The bottom of one side is provided with a stepped groove for placing the free end of the bottom plate, and the bottom of the frame is provided with a telescopic plate that slides horizontally.

By adopting the above-mentioned technical scheme, the front panel and the rear panel are provided with grooves for accommodating the side panels and the bottom panel. After folding, the frame occupies a small area, is convenient for storage, and is easy to operate when folded. At the same time, the bottom panel is also hinged with the bottom of the rear panel. When stowed, the bottom plate can also be turned over and entered into the groove of the rear plate for storage.

Further, the top of the side plate is also provided with a clamping bar for fixing the position of the frame.

By adopting the above technical solution, the frame body is not easily deformed during transportation, and at the same time, the frame body is reinforced.

Further, the handle includes a cylinder fixed to the vehicle frame and a telescopic rod that slides vertically in the cylinder.

By adopting the above technical solution, the handle can also rotate in the cylinder while sliding up and down, which is convenient for the user to adjust the use angle and facilitate the pushing and pulling of the transport trolley.

In summary, the utility model has the following beneficial effects:

1. The medical transport trolley can adjust the height of the frame body by rotating the screw, which reduces the bending of the user during the transportation process and saves more effort. At the same time, the frame body is raised to avoid pouring blood samples from a high place , reducing specimen damage and hemolysis, avoiding affecting diagnosis;

2. The frame of the medical transport trolley adopts a foldable structure, and the frame can be stacked when not in use to reduce the occupied area. At the same time, the handle can be stretched and contracted, which is convenient for users to choose a more labor-saving transportation state during transportation, and has higher flexibility;

3. The wheels of this medical trolley adopt three-arm brackets, and crawling wheels are arranged at the ends. Therefore, when encountering a step block, the three-arm brackets roll forward and climb upwards, so that the crawling wheels at the three ends alternate Crawling has the effect of stably and automatically climbing stairs.
