  However, in the configuration of the above-described known invention, as can be confirmed from the comparison between FIG. 2 and FIG. 3, the upper end of the radius arm (20) (21) that moves in a refraction link moves to the upper frame. Since the lower end of (21) is pivotally connected to a stay that integrally projects obliquely upward from the base frame (10), the support strength of the patient mounted on the surface lying on the upper frame The stability is inferior, and an excessive load acts on the first and second actuators (11) and (12) of the radius arms (20) and (21).

  The first and second actuators (11) and (12) are composed of a hydraulic pump / cylinder assembly, which can be used individually with the pedals (13a) (13b) (14a) (14b) or with the common pedal (15a). (15b) must be stepped on at the same time, and in order to raise and lower the patient slowly and safely, it is necessary to step on the dozens of times each time the patient goes up and down, which is troublesome for nurses and other hospital staff. Evidently, forced to work hard.

  In addition, as can be seen from FIGS. 2 and 4, the horizontal connecting rods traversing the mid-height position of the radius arms (20) and (21) in the left-right direction are the upper arm and the base arm. X-ray tubes and X-ray detectors (image intensifiers) are placed opposite to each other on both ends of the C-shaped arm in order to narrowly block the front and rear surfaces of the internal space partitioned between the top and bottom of (10). The C-shaped arm of the X-ray diagnostic imaging apparatus can be freely inserted into the internal space from the front or rear and used, and the target affected area cannot be photographed or seen through, which is still inconvenient.

  The present invention aims to improve such problems, and in order to achieve the object, according to the first aspect of the present invention, there is provided a cart equipped with a caster braking mechanism and an intermediate portion of the cart via a hanger beam. A pair of symmetrical front and rear electric linear actuators that are axially supported, a lift mechanism that is pivotally connected to the tip of the output advancing / retracting rod that projects from both linear actuators so as to be able to bend, and the lift mechanism Consists of a lifting rack to be lifted and a pair of front and rear patient support decks mounted in parallel on the lifting rack,

The lower end of the lower lift arm is fitted and fixed to a pair of horizontal rotating shafts penetrating horizontally across the front and rear ends of the carriage, and kept in a four-point support state.

As a relationship of maintaining a constant invariable crossing angle in the side view with the lower lift arm from the middle part of the rotating shaft, the tip part of the link piece for the linear actuator projecting integrally in the opposite longitudinal direction and the linear part While the tip of the output advance / retreat rod protruding from the actuator is pivotally connected by a horizontal fulcrum pin,

Of the upper lift arms, the upper end portion of the rear upper lift arm is assembled and fixed to the side frame of the lifting rack as a relationship that maintains a constant crossing angle in a side view,

The upper end of the remaining front upper lift arm is also moved to the side frame of the lifting rack so that a plurality of idler rollers pivotally supported by the former can move in the front-rear direction along the slide guide rail attached to the latter. Engage

It was determined that when the output advancing / retracting rod of the linear actuator was moved back and forth by operating a remote controller, the upper lift arm and the lower lift arm of the lift mechanism moved up and down while maintaining the constant crossing angle. It is characterized by that.

In claim 2 subordinate to claim 1 above, a bed capable of transmitting X-rays such as a carbon fiber reinforced resin plate and an acrylic resin plate attached to the upper surface of the front support deck and the same attached to the upper surface of the rear support deck While cutting the seam with the backrest that can transmit X-rays such as a resin plate as a back-up inclined surface with a certain angle parallel to each other,

  The slide tray can be suspended from a conston spring suspension hook of the rear support deck that is raised and reclined with respect to the front support deck.

  According to the configuration of the first aspect, the lifting mechanism of the lifting rack on which the patient support deck is mounted is lifted and lowered by operating the remote controller with a pair of front and rear electric linear actuators as the driving source. As in the known invention described at the beginning, the operation of stepping on the pedal dozens of times is unnecessary, and the lifting operation can be performed lightly and safely.

Moreover , if the output advance / retreat rods of both linear actuators are advanced / retracted simultaneously by operating the remote controller, the lift rack of the patient support deck can be moved up and down stably while maintaining a horizontal bed state. Similarly, if the output advancing / retracting rods of both linear actuators are moved back and forth separately, the lifting rack of the patient support deck will tilt to the patient's head-up state or head-down state. There is an effect that is useful for collection of the corresponding X-ray image and its operation and treatment.

In addition , when the lifting operation is performed by the linear actuator, the lifting mechanism of the lifting rack swings back and forth smoothly and does not meander and moves up and down smoothly so that there is no possibility of giving the patient a sense of discomfort or anxiety. In addition, an excessive load does not act on the linear actuator. Helps improve durability.

Further , the lifting rack is supported in a four-point support state on the carriage by a total of four pairs of front and rear link arms that form the lift mechanism, and the upper and lower link arms are located between the upper and lower sides of the lifting rack and the carriage. The internal space is divided into a wide open state not only on the left and right side surfaces but also on the front and back sides, so that the C-arm of the X-ray diagnostic imaging apparatus can be inserted into the internal space without any restrictions. The target affected area of the emergency patient can be freely and correctly fluoroscopically transmitted, which is extremely convenient.

In that case, if the configuration of claim 2 is adopted, when the X-ray image is taken of a patient in a posture of lying down with the pair of front and rear patient support decks in an overall horizontal bed state, the air permeability of the seam is provided. It is possible to prevent a possibility that a shadow caused by the phenomenon occurs in the X-ray image.

If the configuration of claim 3 is adopted, the holder for the X-ray film cassette is inserted into the slide tray for the cut holder stored and installed in the matching communication frame of both patient support decks from the left and right sides. Then, by moving the slide tray in the front-rear direction, the target affected part of the patient sleeping on both patient support decks can be freely and correctly imaged.

In that case, if the structure of Claim 4 is employ | adopted, the said slide tray for cassette holders can be stopped to the desired position according to the target affected part of a patient correctly and conveniently, and it is excellent in the positioning operability.

On the other hand, if the configuration of claim 5 is adopted, the target affected area of the patient who is drowning on the back support deck as the backrest can be accurately and conveniently X-rayed by the automatic positioning stop of the Conston spring. effective.

Hereinafter, specific configurations of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 44 show a first embodiment of the stretcher, which is mainly a carriage (S) with a braking mechanism (B). And an elevating rack (R) that is supported so as to be movable up and down via a lift mechanism (U) that can refract on the carriage (S), and can be reclined mounted on the elevating rack (R). X-ray imaging into the frame of both patient support decks (FD) (RD), which consists of a pair of front and rear patient support decks (FD) (RD), and which will be in communication with each other when used in a horizontal bed state The holder (H) of the film cassette (M) is stored and installed so as to be slidable in the front-rear direction via a slide tray (T) therefor.

First, the cart (S) is a plan view extending in the front-rear direction as shown in FIGS. 1 to 7 from a pair of left and right side frames (1) and a plurality of cross frames (2) fixed and mounted between them. The frame is integrated into a substantially rectangular shape (for example, a size of about 1100 mm × about 600 mm), and a pair of bearing masts (3) are vertically fixed near the front and rear ends of each side frame (1). There is also.

In addition, the bearing mast (3) is formed of a square steel pipe similar to the side frame (1) and the cross frame (2), and a stem (4) of a caster (C) is inserted into the individual parts from below and is suspended. Is in a state. Moreover, a total of four casters (C) are of a three-way system that can simultaneously perform braking (rotation stop), straight travel, and 360-degree free turning by the attached braking mechanism (B).

That is, in FIGS. 8 to 13 showing the brake mechanism (B) of each caster (C) extracted, (5) is a rotating cam built in the upper end of the stem (4) so as not to be detached. As shown in FIG. 10, the square core shaft (6) fitted to the square center hole is between the left and right sides of the front bearing mast (3) and between the left and right sides of the rear bearing mast (3). , Each horizontally penetrating horizontally.

A pair of control pedals (7) are fixedly integrated to the left and right ends of the core shaft (6) projecting laterally from the front bearing mast (3) and the rear bearing mast (3). The turning cam (5) can be turned by the stepping operation.

The circumferential surface of the rotating cam (5) functions as a cam surface (5a) for stopping the rotation of the caster. On the circumferential surface, a shallow caster straight traveling cam groove (5b) as shown in FIG. The turning cam groove (5c) is also notched. The free cam cam groove (5c) has a radial length from the rotation center of the rotary cam (5) through the cam groove (5b) for straight traveling from the cam surface (5a) for rotation stop of the caster (C). The difference is changed in three stages that become shorter as you go.

(8) is an elevating rod inserted and suspended along the axis of the stem (4), and a head (9) having a convex curved surface at its upper end is pushed up by a return spring (compression coil spring) (10). While receiving the force, it is always pressed against the rotating cam (5), and similarly, the lower end of the lifting rod (8) is formed as a lifting plate (11). (12) is a rotation preventing tooth engraved on the lower surface of the elevator board (11).

Further, (13) is a turning yoke fitted to the lower end portion of the stem (4) through a ball bearing (14) so as not to fall off. A wheel (15) is attached to the lower end portion of the turning yoke (13). It is pivotally supported. (16) is a fan-shaped brake board that is pivotally attached to the midway height position of the swing yoke (13), and is interposed in a partitioned state between the upper and lower boards (11) and the wheels (15). There is a swivel prevention tooth (17) engraved on the upper face of the swivel prevention tooth (12) of the elevator board (11), while a wheel braking shoe (18) lined on the lower face is also The rotation of the wheel (15) can be prevented.

Furthermore, (19) is a sheath tube inserted into each of the square core shafts (6), and is integrated with the core shaft (6) by a plurality of pressing bolts (20) as shown in FIGS. It is assembled so that it can rotate. In addition, the rotating link pieces (21) that integrally project from the corresponding midway part of the front side sheath tube (19) and the rear side sheath tube (19) can move the forward / backward rod (22) in the front-rear direction. It is pivotally connected through.

As a result, from the floating state of FIGS. 9 and 11 in which the head (9) of the lifting rod (8) is engaged with the caster free turning cam groove (5c) of the rotating cam (5), the control pedal ( 7) by stepping in the direction of arrow (F1) in FIG. 11, the rotation built in the stem (4) of the caster (C) via the sheath tube (19) and the core shaft (6). The cam (5) is rotated by a certain angle while resisting the push-up biasing force of the return spring (10), and the lifting rod (8) is moved to the cam groove (5b) for straight traveling of the rotating cam (5). When the head (9) is engaged, the swivel prevention teeth (12) of the lift plate (11) in the lowered lift rod (8) mesh with the swirl prevention teeth (17) of the brake plate (16). The caster (C) becomes unable to turn and only goes straight ahead. .

On the other hand, when the control pedal (7) is further depressed in the direction of the arrow (F2) in FIG. 13 from the straight traveling state of the caster in FIG. 12, the rotating cam (5) is rotated by a certain angle, and the rotating cam If the head (9) of the lifting rod (8) is engaged with the caster rotation stop cam surface (5a) of (5), the lifting plate (11) of the lifting rod (8) lowered further down will be Since the brake board (16) is pushed down while maintaining the meshed state with the brake board (16), the rotation of the caster (C) is prevented by the frictional force of the wheel brake shoe (18).

In this case, the control pedal (7) is fixed to the left and right ends of the front core shaft (6) and the rear core shaft (6) as a total of four, and the front sheath tube (19) and the rear Since it is pivotally connected to the side sheath tube (19) via the advance / retreat rod (22), a total of four casters (C) can be obtained by depressing one of the control pedals (7). Can be switched at the same time by braking (stopping rotation), traveling straight, or freely turning 360 degrees, which is useful for emergency use and patient safety.

However, as apparent from FIGS. 45 to 52 showing the second and third embodiments described later, a frame-shaped control pedal (7) integrally projecting forward from the front sheath tube (19) and the rear sheath tube You may just install two pairs with the frame-shaped control pedal (7) which protrudes back from (19) in reverse. This is because the switching operation can be performed in the same manner. Note that a two-way caster (C) in which only the straight traveling cam groove (5b) is omitted may be employed.

Next, reference numeral (23) in FIGS. 1 to 7 is an H-shape in a bottom view of the two side frames (1) of the carriage (S), and is integrated downward from an intermediate portion of the two side frames (1). A pair of front and rear slide guide rails (24) for parallel support bases, and a pair of front and rear linear actuator bearing stays (25) are attached and installed on the inner surface. ing.

(26) is a control unit support base engaged with both slide guide rails (24) of the hanger beam (23), on which a control unit (27) for controlling a linear actuator, which will be described later, is mounted. The support base (26) can be pushed or pulled out from the lateral direction along the slide guide rail (24) as shown in FIG. (28) is a handle for slide operation for that purpose. It should be noted that a cord plug (not shown) from the control unit (27) can be inserted into a power outlet for charging.

(A) is a pair of front and rear electric linear actuators that form the drive source of the lift mechanism (U) mentioned earlier, and is a screw spindle (30) rotated by a reversible motor (29) as shown in FIGS. ), A transmission nut (31) screwed and fastened thereto, and an output advancing / retracting rod (32) coupled to and integrated with the transmission nut (31) as a covered state covering the screw spindle (30). The output advance / retreat rod (32) is reciprocated linearly by the reversible motor (29). (33) shows a transmission bevel gear device interposed between the reversible motor (29) and the screw spindle (30).

The pair of front and rear linear actuators (A) are arranged in a symmetrical manner, and the base end portion of the main body case (34) is placed horizontally to the linear actuator bearing stay (25) of the hanger beam (23). While being pivotally attached via a fulcrum pin (35), the tip of the remaining output advance / retreat rod (32) is pivotally connected to a later-described linear actuator link piece of the lift mechanism (U).

(36) shows the hand-held remote controller of the control unit (27) for controlling the linear actuator, which includes the output advancing / retracting rods (32) of both linear actuators (A) as shown in FIGS. Two operation buttons (37) for advancing or retreating and four operation buttons (38) for advancing or retreating the output advancing / retreating rod (32) separately in front and rear are provided in parallel.

Therefore, the control unit (27) is remotely operated by selecting and using the operation buttons (37) and (38), and the lifting rack (R) of the patient support deck (FD) (RD) is set as shown in FIGS. It can be tilted not only in the horizontal bed state but also in the head-up state or the head-down state of the patient as shown in FIGS. 20 and 21, which is extremely convenient for use as an operating table or a treatment table. Expands compatibility. As the remote controller (36), it may be possible to adopt a wireless system. (Α) indicates an inclination angle (for example, about 15 degrees) of the lifting rack (R) in the head-up state or the head-down state.

The lifting rack (R) mentioned above extends from the pair of left and right side frames (39) and a plurality of cross frames (40) fixedly mounted on the upper surface thereof in the front-rear direction as shown in FIGS. The frame is integrated into a substantially rectangular shape (for example, a size of about 1970 mm × about 600 mm) in a plan view, and holds the pair of left and right hand push handles (41) projecting from the rear end portion, and the cart (S) Is supposed to run. Both side frames (39) are made of square steel pipes, and the cross frame (40) is made of square steel pipes or channel groove steel.

The lifting mechanism (U) of the lifting rack (R) is composed of a total of four upper lift arms (42), one pair at the front and rear, and a total of four lower lift arms (43), one pair at the front and rear. The left and right pairs of the upper lift arm (42) and the lower lift arm (43) are pivotally connected to each other via respective short horizontal fulcrum pins (44).

(45) is a pair of horizontal rotating shafts penetrating and horizontally extending at both front and rear end portions of the side frames (1) in the cart (S), the front rotating shaft (45) and the rear rotating shaft. The lower end of the lower lift arm (43) forming the lift mechanism (U) is fitted and fixed to the vicinity of both left and right ends of (45) as shown in FIGS. ) In the four-point support state. Similarly, linear actuator link pieces (46) are integrally projected from corresponding intermediate portions of the front rotation shaft (45) and the rear rotation shaft (45).

The projecting tip of the link piece (46) and the tip of the output advance / retreat rod (32) of the linear actuator (A) are pivotally connected to each other via a horizontal fulcrum pin (47). Therefore, the lift mechanism (U) of the lifting rack (R) is lifted and lowered by a certain stroke (for example, about 560 mm to about 1050 mm) by the linear actuator (A).

In that case, the lower lift arm (43) and the link piece (46) in the lift mechanism (U) are in a fixed state, preferably maintaining a constant crossing angle (β) of about 90 degrees when viewed from the lateral direction, Even if the lift mechanism (U) is moved up and down, the crossing angle (β) does not change.

On the other hand, a reinforcing plate (48) aligned with the side frame (39) of the lifting rack (R) is fixedly integrated with the upper end of the upper lift arm (42) that also forms the lift mechanism (U). Although the lift arm (42) is also in a four-point support state, the upper lift arm (42) and the side frame (39) preferably have a constant crossing angle (γ) of about 100 degrees when viewed from the side. Keep.

However, the reinforcing plate (48) attached to the rear (patient's head) upper lift arm (42) of the upper lift arms (42) arranged in parallel one by one in the front and rear is as shown in FIGS. A plurality of bolts (50) are fixed and integrated to the inner surface of the side frame (39) in the lifting rack (R) via a spacer (49).

On the other hand, a plurality of idler rollers (51) as shown in FIGS. 24 to 26 are pivotally supported by the reinforcing plate (48) of the remaining front side (patient foot side) upper lift arm (42). A channel groove type slide guide rail (52) that engages with the idler roller (51) is attached to and integrated with the inner surface of the side frame (39) in the lifting rack (R). It can move in the front-rear direction.

As a result, the lifting mechanism (U) of the lifting rack (R) does not swing in the front-rear direction and does not meander during the lifting operation by the linear actuator (A) as shown in FIGS. ) In a stable state with the constant crossing angles (β) and (γ) maintained constant, it moves up and down smoothly so as to go straight up and down, and there is no possibility of giving the patient a sense of discomfort or anxiety. This is because the wobbling motion meandering in the front-rear direction can be reliably absorbed by the moving action of the free-rolling roller (51) along the slide guide rail (52).

Further, (G) is a pair of left and right folding safety fences for protecting a patient, each of which is a plurality of parallel link columns (53) and a horizontal hand extending a predetermined length (for example, about 1200 mm) in the front-rear direction. The lower end of each link column (53) is connected to the outer side surfaces of both side frames (39) of the lifting rack (R) via fulcrum bolts (55). On the other hand, since the upper end of each link column (53) is pivotally attached to the handrail bar (54) by the fulcrum pin (56), it is pushed forward or backward as shown in FIG. Can be

The safety fence (G) lying down in the flat state is set to have the same installation height as the lower border frame (to be described later) of the patient support deck (FD) (RD) or to be retracted below this. Therefore, it is possible to transfer patients without any problems. In addition, although illustration is abbreviate | omitted, it cannot be overemphasized that the safety fence (G) is locked so that it may not fall down accidentally from a standing state.

Next, with respect to the pair of front and rear patient support decks (FD) (RD), the front support deck (FD) corresponding to the lower body of the patient is in a horizontally fixed installation state. The rear support deck (RD) located at the corresponding position is in a state of being generally horizontal with the front support deck (FD), and can be reclined as shown in FIG. It is like that.

That is, the front support deck (FD) is a pair of upper and lower border frames (57) (58) bent in a substantially U shape (for example, a size of about 980 mm × about 600 mm) in a plan view extending elongated in the front-rear direction. And a plurality of spacers (59) vertically suspended from each other, the frame is integrated into a flat table type that maintains a constant slide tray storage interval (d) (for example, about 95 mm). The frame (57) (58) and the spacer (59) are both made of square steel pipe.

And the lower surface of the lower border frame (58) which forms such a front support deck (FD) is firmly integrated with the upper surface of the cross frame (40) in the lifting rack (R). (60) is a pair of left and right parallel tray slide guide rails fixed to the inner surface of the upper border frame (57), and is composed of channel groove steels of a fixed length facing each other, for cassette holders between them. The slide roller (T), which will be described later, moves in the front-rear direction while being engaged.

In this case, the upper edge frame (57) and both slide guide rails (60) are aligned in a flat flush state on the lower surfaces thereof as shown in FIGS. A pair of left and right (iron plate) (61) is fixedly integrated. Therefore, the magnet adsorption plate (61) also serves as reinforcement of the upper edge frame (57) and the slide guide rail (60).

(62) is a bed (top plate) attached and fixed to the upper surface of the upper edge frame (57) by a plurality of countersunk screws (63) so as to cover the inside of the front support deck (FD). It consists of a carbon fiber reinforced resin plate (CFRP) or an acrylic resin plate having a certain thickness that can transmit X-rays.

Moreover, as shown in FIGS. 27 to 29, the rear end of the bed (62) is cut as a rearwardly inclined surface of a certain angle (δ) (for example, about 20 to 30 degrees). The surface is covered with an elastic film (64) such as polyester fiber.

On the other hand, the rear support deck (RD) is a pair of upper and lower border frames (65) bent in a substantially U shape (for example, a size of about 870 mm × about 600 mm) in plan view facing the front support deck (FD). (66) and a plurality of spacers (67) vertically suspended from each other, the frame is integrated into a flat table shape that maintains the same constant slide tray storage interval (d), and the horizontal bed state The comrades in the frame of both patient support decks (FD) (RD) in parallel with each other are in communication. Moreover, the frame (65) (66) and the spacer (67) of the rear support deck (RD) are also made of the same square steel pipe as those of the front support deck (FD).

However, unlike the front support deck (FD), such a rear support deck (RD) is not fixedly integrated with the cross frame (40) of the lift rack (R), and the lift rack (R). From FIG. 30, it is kept in a separated state capable of floating.

(68) is a pair of left and right pneumatic cylinder bearing stays that project rearward and integrally from the cross frame (40) of the lifting rack (R) located near the front end of the rear support deck (RD). 69) is a pneumatic cylinder bearing stay projecting forward integrally from the vicinity of the rear edge of the lower border frame (66) of the rear support deck (RD) as a pair of left and right sides facing and corresponding thereto. A pair of left and right pneumatic cylinders (gas dampers) (70) are interposed between the front and rear sides of the bearing stays (68) and (69).

Similarly, from the intermediate position of the rear end portion of the lower edge frame (66) of the rear support deck (RD), as shown in FIGS. 33 to 35, the support fork for the hanging hook (71) of the slide tray (T) is provided. ), And the boss (74) of the suspension hook (73) for the Conston spring is pivotally attached to the support fork (71) via a horizontal fulcrum pin (72). Has been.

It intersects with the hanging hook (73) by a certain angle. Reference numeral (76) denotes a suspension hook return spring (bend spring) wound around the fulcrum pin (72), and the suspension hook (73) is inwardly locked with a suspension ring of a conston spring described later. Rotating bias is applied.

Further, (77) is a pair of left and right horizontal tray slide guide rails fixed to the inner surface of the upper edge frame (65) forming the rear support deck (RD), and has a channel groove facing each other with a fixed length. The running rollers of the cassette holder slide tray (T) are engaged with each other.

When the pair of front and rear patient support decks (FD) (RD) are kept in the entire horizontal bed state as shown in FIGS. 1 to 6, the slide guide rail (77) for the tray on the rear support deck (RD) is the front side. Correspondingly matches the tray slide guide rail (60) of the support deck (FD), the cassette holder slide tray (T) can be moved in the front-rear direction along the entire length along these. It is.

At that time, the upper edge frame (65) of the rear support deck (RD) and the slide guide rail (77) are also in a flat flush state with the lower surfaces as shown in FIGS. A left and right pair of suction plates (iron plates) (78) for use are fixedly integrated.

For example, an emergency patient who is comfortably transported to the patient support deck (FD) (RD) at the lowered position can be smoothly and conveniently transferred to the existing bed of the hospital by the subsequent lifting operation, and the operation is also linear. This can be done easily by the remote controller (36) for the control unit (27) of the actuator (A).

In addition, a pair of left and right parallel slide guide rails (60) and (77) are arranged in a row on the upper border frames (57) and (65) of both patient support decks (FD) and (RD). The cassette holder (H) of the film cassette (M) for X-ray photography is inserted into the frame of the slide tray (T) for film cassette, which can be moved in the front-rear direction. Therefore, in the horizontal bed state of both patient support decks (FD) and (RD) as shown in FIGS.

In that case, the film cassette slide can be removed by removing the hanging ring (111) of the slide tray (T) from the conston spring hanging hook (73) attached to the rear support deck (RD). The tray (T) can be moved and operated along the longitudinal direction of both patient support decks (FD) (RD) from the patient's head to the foot with a long stroke, and the magnet (113) is removed. Since the slide tray (T) can be sucked and fixed to a desired stop position by rotating the handle (114), the target affected part of the patient can be freely and correctly X-rayed. You can shoot.

On the other hand, the horizontal fulcrum pins (85) of both side connecting plates (83) are moved from the entire horizontal bed state with the rear support deck (RD) to the front support deck (FD) as shown in FIGS. It is possible to recline to a desired inclination angle (θ) as the center, and when the rear support deck (RD) is raised as a backrest, the slide cassette (T ) Is suspended on the suspension hook (73) for the conston spring of the rear support deck (RD), and the slide tray (T) is automatically stopped by pulling down the conston spring (108). X-ray imaging of the target affected part of the patient who is in a position drooping into the rear support deck (RD) at the desired installation height is also possible. In it, there is no possibility to give a burden to the patient.

Further, the lift mechanism (U) of the lifting rack (R) operated by the front and rear pairs of the electric linear actuator (A) has a total of four lower lifts as well as a total of four upper lift arms (42). As shown in FIG. 1, the lifting rack (R) is composed of an arm (43), and the left and right pair of the arms (43) stays in a refractably pivotally connected manner via separate horizontal fulcrum pins (44). 2, the internal space (Z) partitioned between the upper and lower sides of the lifting rack (R) and the carriage (S) is maintained in a fully opened state of both the front and rear surfaces and the left and right side surfaces. There is nothing to block this narrowly.

As a result, as suggested in FIG. 2, an X-ray diagnostic imaging in which an X-ray tube (137) and an X-ray detector (image intensifier) (138) are installed at both ends of the C-shaped arm (136). The C-shaped arm (136) of the apparatus (E) can be freely inserted into the internal space (Z) from any of the front-rear direction and the left-right lateral direction, and can be freely used. It is also possible to accurately and conveniently see through the target affected area of the patient by the device (E).

When X-ray fluoroscopy is performed, the X-ray diagnostic imaging apparatus (E) is fixed in the installed state, and the carriage (S) is moved in the front-rear direction relative to the X-ray diagnostic imaging apparatus (E). Even when the rear support deck (RD) is reclined to a desired inclination angle (θ), such X-ray fluoroscopy can be performed without any problem.

It should be noted that, in any posture, whether the patient's target affected area is photographed or seen through, or used as a patient's operating table or treatment table, a total of four casters (C) attached to the carriage (S) are used. Since the brake mechanism (B) can be stopped at once, it is excellent in use convenience and patient safety.

Next, FIGS. 45 to 49 show a stretcher according to a second embodiment of the present invention, in which both front and rear ends of the lifting rack (R) are handle bars (139) and both side frames (39).
