Embodiment Construction

[0017] The frame of a cart, such as figure 1 figure 2 , The vehicle frame is made up of ring pipe frame 4, support rod 5, supporting leg 6, and universal wheel 7. The ring pipe frame is only 1400 mm long. There are three decks placed on the ring pipe frame. The order is the head deck 1, the middle deck 2, and the foot deck 3. The head deck is fixed on the hoop rack with screws. The inner end of the deck is inserted into the sleeve of the deck by 25mm, and the other end of the deck is also inserted into the sleeve by 25mm by the foot deck. The deck is restricted by two sets of hook stoppers at both ends. Move forward or backward along the track formed by the head rest and foot rest. Conduit is equipped with below foot resting board, and conduit is enclosed within on the ring pipe frame, makes foot resting board only advance and retreat along the straight line of ring pipe frame. The deck group composed of three decks has a total length of 1850 mm and a width of 550 mm. The ...

Abstract

The invention relates to stretcher reconstruction and provides a telescopic boat-shaped stretcher applicable for standard series elevators, aiming at solving the problem that it is difficult for traditional stretchers to pass in and out of elevators. The stretcher is characterized in that a lying board of the stretcher is boat-shaped in general; two sides of the lying board are straight lines, and two ends are elliptical curves with one end being relatively sharp which is half of an elliptical curve divided by a short axis, and with the other one being relatively obtuse which is half of an elliptical curve divided by a long axis. the stretcher is provided with a head lying board, a intermediate lying board, and a foot lying board; among the three lying boards, the intermediate board is an intermediate sleeve made of a stainless sheet steel with thickness of about 3mm and is provided with a vertical rib plate and a hook-head block device; the vertical rib plate can increase the stiffness and improve the structure, and the hook-head block device enables orderly relative motion with constraint of the three lying boards; parts of the head lying board and the foot lying board can be retracted into the intermediate lying board and therefore length contraction is realized.

Description

technical field [0001] The invention relates to a medical device, in particular to a stretcher trolley capable of entering and exiting an elevator car. Background technique [0002] There are more and more rescue difficulties caused by narrow elevator cars in high-rise residential buildings, which directly affects the rescue of patients and even endangers their lives. The new version of the National "Residential Design Code" was implemented on August 1, 2012. The new code stipulates: "For residential buildings with 12 floors and above, there should be no less than two elevators in each building, and one of them should be installed Elevators for stretchers". This new regulation puts forward new requirements for stretchers, and innovative solutions for various special stretchers suitable for elevators continue to emerge. The idea of ​​this kind of innovation mainly has the following three directions. One is the folding type, which shortens its horizontal projection length wh...
