The size of the film cassette (M) Excellent adaptability to changes in height and convenience in use.

Since the stretcher of the present invention has the above-described configuration, it is of course possible to carry an emergency patient while keeping the pair of front and rear patient support decks (FD) (RD) in an overall horizontal bed state. In this case, both the patient support decks (FD) and (RD) are lifted by a lift mechanism (U) driven by a hydraulic jack (J), as is apparent from the comparison between FIG. 1 and FIG. Since it can be adjusted up and down, for example, a patient carried comfortably at a lowered position can be smoothly and conveniently transferred to a ready-made bed in a hospital by a subsequent raising operation.

In addition, a pair of left and right parallel slide guide rails (68) (95) are arranged in a row on the upper border frame (62) (79) of both patient support decks (FD) (RD). The holder (H) of the film cassette for X-ray photography (M) is inserted into the frame of the slide tray (T) for film cassette that can move in the direction so that it can be freely inserted and removed from the lateral direction. Therefore, in the horizontal bed state of both patient support decks (FD) and (RD) as shown in FIGS.

In that case, the slide tray (T) is removed by removing the suspension ring (139) of the slide tray (T) from the conston spring suspension hook (90) attached to the rear support deck (RD). Both patient support decks (FD) and (RD) can be moved and moved in the longitudinal direction with a long stroke, and the slide tray (T) can be moved to the desired stop position by operating the knob handle of the magnet (141). Since the patient can be adsorbed and fixed, the target site of the patient can be freely and correctly imaged.

Further, the rear support deck (RD) is reclined from the entire horizontal bed state with the front support deck (FD) around the horizontal fulcrum pin (104) of the connecting plate (101) as shown in FIG. When the rear support deck (RD) is erected as a backrest, as apparent from FIG. 3 and FIGS. 37 to 40, the suspension ring (139) of the slide tray (T) is moved to the rear side. At the desired installation height where the slide tray (T) is automatically stopped when the conston spring (134) is pulled down, the rear support deck (RD) is locked to the conston spring suspension hook (90) of the support deck (RD). It is also possible to accurately and conveniently take X-ray images of patients who are drowning in this manner, which is useful for X-ray imaging of patients with water in the lungs or knees.

In that case, the rear support deck (RD) is used to prevent the suspension state of the suspension ring (139) and the suspension hook (90) from being released and the slide tray (T) falling. 41), a rotating handle shaft (160) as shown in FIGS. 41 and 42 is horizontally penetrated to the vicinity of the front end portion (lower end portion) of the lower border frame (80). A pair of left and right pins (162) that can be received by the slide tray (T) are preferably integrally projected from a middle portion of the handle shaft (160) that is rotated by the handle (161).
