Since the moving amounts of the first and second two hydraulic cylinders are added together, the mounting section can be quickly moved relative to the base at twice the speed of each hydraulic cylinder. Furthermore, the length of each of the first and second two hydraulic cylinders is approximately the length A of the moving distance of the mounting section.

G. Example Hereinafter, an example in which the present invention is applied to an obstetrics and gynecology examination table will be described with reference to the drawings.

G. First, the entire examination table will be explained with reference to FIGS. 1A and 1B.

This examination table has a seat plate 2 constituting a patient placement part 1, a back plate 3.4 divided into upper and lower parts, a pair of left and right throw supports 5, a material support 6 that also serves as an upper limb stand, etc. . These placing parts 1 are supported on a base 7 so as to be movable up and down by a lifting device which will be described later. Note that both back plates 3.4 are supported so as to be able to change their angle and to be movable in the front and back direction relative to the seat plate 2 by an angle changing mechanism and a back and forth moving mechanism that will be described later. Further, at the lower part of the seat plate 2, there are provided a removable sewage receiver 8, a sewage scattering prevention Fi 9, and the like.

According to this examination table, first, as shown in FIG. Place your buttocks on the seat plate 2, lean your hips and back on the back plate 3.4, spread your legs apart and place them on the receivers 5 to maintain a vertical sitting posture with your legs spread. Take.

Next, the placing unit 1 is raised obliquely forward in the direction of arrow a from the lowered position shown in FIG. 1A to the upper front elevation position shown in FIG. 1B. The back plate 3 on the tip side is moved forward in the direction of arrow C while tilting backward in the direction of the arrow C together with the throw tray 5 and the material tray 6.
is moved to a position above the seat plate 2.

Then, due to the backward tilt of the back plate 3.4, the patient's waist and back come to rest almost horizontally on the back plate 3.4, and the patient's center of gravity shifts from above the seat plate 2 to above the back plate 3.4. At the same time, the patient's body position is adjusted to a horizontal position with the legs tilted open. Then, the patient is moved forward in the horizontal position by moving the placing part 1 obliquely forward in the direction of arrow a and moving the back plate 3.4 forward in the direction of arrow C. The seat (examination area) of the patient is brought closer to the doctor through the curtain.

At this time, the back plate 3 is moved to a position above the seat plate 2 in the direction of arrow C, and as a result, the seat plate 2 is stored below the back plate 3 in the opposite direction to the direction of arrow C.

In addition, as the back plate 3 moves in the direction of arrow C, the sewage receiver 8 and the sewage scattering prevention plate 9 move from the storage position at the bottom of the seat plate 2 to the seat plate 2.
automatically pulled out to the front drawer position.

This examination table has all controls such as raising and lowering the platform 1, changing the angle of the back surface 3.4 with respect to the seat plate 2, moving it back and forth, and putting in and taking out the sewage receiver 8 and the sewage scattering prevention plate 9. This is done using a hand switch (not shown).

02 Next, the elevating device 11 of the placing section 1 will be explained with reference to FIGS. 2A to 2C.

This lifting device 11 has a lower bracket 12 fixed to a base 7, and a front end side of a parallel link I4 of equal length constituting a first parallel link mechanism 13 is rotated in the directions of arrows a and a' by a rotation fulcrum 14a. It is installed so that it can move freely. and,
The intermediate bracket 15 is rotatably attached to the rear end side of the parallel link 14 by the rotation fulcrum 14b, and the rear end side of the parallel link 17 of equal length constituting the second parallel link mechanism 16 is attached by the rotation fulcrum 17a. It is mounted rotatably in the directions of arrows d and d'. The mounting portion 1 is attached to an upper bracket 18 to which the front end side of the parallel link 17 is rotatably attached via a rotation fulcrum 17b. In addition,
The first parallel link mechanism 13 is long, and the second parallel link mechanism 1
6 is short. And the lower bracket 12
A first drive means 19 that swings the first parallel link mechanism 13 in the directions of arrows a and a' about the pivot point 14a.
and the second parallel link mechanism 1 with respect to the intermediate bracket 15.
A second drive means 20 is separately provided for swinging the drive unit 6 in the directions of arrows d and d' about the pivot point 17a. Incidentally, these first and second driving means are constituted by hydraulic cylinders.

According to this lifting device 11, by swinging the first parallel link mechanism 13 with respect to the lower bracket 12 in the direction of the arrow a1a' about the rotational fulcrum 14a by the first drive means 19, the first parallel The link mechanism 13 is
The lower bracket 12 swings between a laid down position where it is laid down almost horizontally on the rear side of the lower bracket 12 as shown in Figure A, and an upright position where it is raised up to a predetermined angle forward and upward from the laid down position as shown in Figure 2B. Can be driven. At this time, since the first parallel link mechanism 13 performs parallel movement, the placing section 1 is
It can be raised and lowered by parallel movement in the directions of arrows a and d' between the lowered position shown in Figure A and the raised position shown in Figure 2B, which is located above and in front of the lowered position. Therefore, the seat plate 2 is raised and lowered while always maintaining a substantially horizontal state. By raising the receiver 1 diagonally forward in the direction of arrow a from the lowered position to the upper position, the patient's seat (examination section) on the receiver 1 can be brought closer to the doctor through the curtain. .

Next, when it is necessary to adjust the height of the mounting portion l that has been raised to the raised position, the second parallel link mechanism 16 is moved relative to the intermediate bracket 15 by the second driving means 9, as shown in FIG. 2C. The height of the mounting section 1 can be freely adjusted by swinging the mounting section 1 about the pivot point 17a in the vertical directions of arrows d and d'. At this time, since the second parallel link mechanism 16 performs parallel movement, the patient's seat on the placement unit 1 (
The height of the medical examination section can be adjusted with almost no change in the position of the medical examination section) in the direction of arrow e, which is the front-rear direction.

G3 Next, according to FIGS. 3A to 3D, the back plate 3.4
The angle changing mechanism 22 will be explained.

This angle changing mechanism 22 has the lower end of the angle adjusting plate 23 pointed at the upper end of the upper bracket 18 by a rotation fulcrum 24.
The angle adjusting plate 23 is attached to the upper bracket 18 so as to be rotatable in the b'' direction. A driving means 25 is provided for swinging the angle adjustment plate 23 in the b'' direction as shown by the arrow, about the rotational fulcrum 24 with respect to the upper bracket 18. There is.

Note that this driving means 25 is composed of a hydraulic cylinder. In addition, the back plate base 2 of the back plate 3.4 is divided into upper and lower parts.
6.27 are rotatably connected to each other by a rotation fulcrum 28, and the upper back plate 4 is connected to the angle adjustment plate 23 by a guide mechanism 29 in the direction of arrow f.

f′ is mounted so as to be movable in the force direction. This guide mechanism 29 includes a pair of parallel guide shafts 31 on the left and right sides of a slider 30 disposed between the angle adjustment plate 23 and the back plate base 27.
A pair of guide pulleys 32 and 33 rotatably attached to the angle adjustment plate 23 and the back plate base 27 are engaged with the outside and inside of each of these parallel guide shafts 31, respectively. Therefore, the slider 30 is configured to be movable in the directions of arrows f and f' with respect to the angle adjustment plate 23 by the parallel guide shaft 31 and the guide pulley 32, and the back plate base 27 is configured to be movable with respect to the slider 30 by the parallel guide shaft 31 and the guide pulley 32. It is configured to be movable in the directions of arrows f and f' by a pulley 33. A pair of rollers 34 is attached to both left and right ends of the rotation fulcrum 24, and a pair of left and right guide rollers 35 is attached to the lower end of the back plate base 26. Further, a seat plate base 36 of the seat plate 2 is commonly rotatably attached to the rotation fulcrum 24, and this seat plate base 36 is always in contact with the front surface 18a of the upper bracket 18 under its own weight. Furthermore, a pair of left and right guide rails 37 are provided substantially horizontally on the seat plate base 36.

According to this angle changing mechanism 22, the angle can be adjusted by one degree by swinging the angle adjusting plate 23 with respect to the upper bracket 18 in the directions of the arrows f and f' about the rotation fulcrum 24 using the driving means 25. The plate 23 allows the back plate 3.4 to stand up at a predetermined angle with respect to the seat plate 2 in a substantially flush state as shown in FIG. 3A, and the upper back plate 4 to the third
As shown in figure c, a predetermined angle (about 15
It can be driven to swing in the directions of arrows A and b' between the rearward tilted position θ2 and the rearward tilted position θ2.

At this time, the direction of the arrow b' of the angle adjustment plate 23
Simultaneously with the swinging in the direction, the upper back plate base 27 is moved in the direction of the arrow f or the direction of the arrow f' with respect to the angle adjustment plate 23 by a back and forth movement mechanism described later. Therefore, the back plate 3.4 is moved in the direction of the arrow f while being tilted backwards from the upright position of FIG. 3A to the rearward tilted position of FIG. 3C. At this time, when the upper back plate base 27 is driven to move in the direction of the arrow f while being guided by the guide mechanism 29 by the back and forth moving mechanism, the lower back plate base 26 initially moves as shown in FIG. It is moved on both rollers 34 in the direction of arrow f.

Then, as shown in FIGS. 3B and 3C, the back plate base 26 is moved to the seat plate base 3 by both guide rollers 35.
6 on both guide rails 37, and the back plate base 27
is centered around the rotational fulcrum 28 with respect to the back plate base 26
While being rotated in this direction, it is pushed forward in the direction of arrow C by both guide rollers 35 on both guide rails 37. As a result, at the same time as the back plate 3.4 tilts backward in the direction of arrow A, the back plate 3 on the tip side (lower end side) moves forward in the direction of arrow C to a position above the seat plate 2, as shown in Fig. 3C. The back plate 3 is moved and finally becomes almost horizontal.

The pair of left and right projection/receiver 5 and light emitting light 6 shown in FIGS. 1A to 2C are attached to a pair of left and right substantially L-shaped double-sided frames 38 fixed to both left and right sides of the back plate base 26. The projection/reception 5 and the emitted light 6 are moved integrally with the back plate base 26 via the frames 38 on both sides.

Then, by tilting the back plate 3.4 backward in the direction of arrow C, the patient's body position is adjusted from the vertical sitting position to the horizontal position, and by moving the back plate 3 forward in the direction of arrow C, the patient's body position is adjusted to the horizontal position. The patient's seat (examination area) is adjusted to be close to the doctor through the curtain.

In addition, when a patient develops anemia during a medical examination, as shown in FIG. tilt backwards. At this time, when the back plate 4 is in a horizontal state where it is almost flush with the back plate 3, the front end surface 23a of the angle adjustment plate 23 comes into contact with the seat plate base 36, and from then on, the angle adjustment plate 2
By tilting backward in the direction indicated by the arrow 3, the back plate 3 is swung integrally with the back plate 4 via the seat plate base 36 in the direction indicated by the arrow about the pivot point 24.

04 Next, as shown in FIGS. 4A and 4B, the back plate 3.
The longitudinal movement mechanism (double speed drive device) 41 of No. 4 will be explained.

This back-and-forth movement mechanism (double speed drive bag W) 41 drives the back plate 4, which is a placement part, at double speed in the direction of arrows -Eilf and f', which are the back and forth directions, with respect to the angle adjustment plate 23, which is a base. . That is, the tip of the piston rod 43, which is one end 42a of the first fluid pressure cylinder 42 constituted by a hydraulic cylinder, is connected to a bracket 44 that is integrated with the back plate base 27.
A cylinder 45, which is the other end 42b, is connected to a bracket 46 that is integrated with the slider 30, which is a connecting member.

Also, a second fluid pressure cylinder 4 configured with a hydraulic cylinder
One end 47a of the cylinder 48 is connected to a bracket 49 that is integrated with the angle adjustment plate 23, and the other end 47b of the piston rod 50 is connected to a bracket 51 that is integrated with the slider 30 that is a connecting member. and pistons 52.53 in cylinders 45.48 and 52.53 respectively.
Of the pressure oil chambers 54a, 54b and 55a, 55b separated by , 54b and 55b are communicated by a flexible vibe 56, and each pressure oil chamber 54a, 55a is connected to an oil supply/drainage pipe 57.
58 are connected.

According to this back-and-forth movement mechanism (double speed drive device) 41, the fourth
As shown in Fig. A, with the back plate 4 being moved backward in the force direction of arrow f', pressure oil is supplied into the pressure oil chamber 54a of the first fluid pressure cylinder 42 by the oil supply/drainage pipe 57, and When the pressure oil in the pressure oil chamber 55a of the second fluid pressure cylinder 49 is discharged by the oil drain pipe 58, the piston 52 in the cylinder 45 is moved in the direction of arrow f, as shown in FIG. 4B, and the piston rod 43 is moved. The back plate base 27 is indicated by the arrow ``
be moved in the direction. Then, the pressure oil in the pressure oil chamber 54b of the first fluid pressure cylinder 42 is supplied into the pressure oil chamber 55b of the second fluid pressure cylinder 47 through the flexible pipe 56, and the piston 53 in the cylinder 48 moves toward the arrow f. The slider 30 is moved in the direction of the arrow f via the piston rod 50. As a result of the above, the moving amounts of the other ends 42b and 47b of the first and second fluid pressure cylinders 42 and 47 are added together by the slider 30, and the other ends 4
2b and 47b are moved simultaneously in the same direction, the arrow f direction, and the back plate 4 can be quickly moved in the arrow f direction at twice the speed of the first and second fluid pressure cylinders 42,47. Note that when the back plate 4 is moved back in the direction of the force indicated by the arrow r', pressure oil is supplied into the pressure oil chamber 55a of the first fluid pressure cylinder 47 through the oil supply and drainage pipe 58, and pressure oil is supplied through the oil supply and drainage pipe 57 into the pressure oil chamber 55a of the first fluid pressure cylinder 47 The pressure oil in the pressure oil chamber 54a of the second fluid pressure cylinder 42 is discharged.

Therefore, according to this back-and-forth movement mechanism (double speed drive device) 41, in the case of emergency bleeding of a patient, etc., the back plate 4 can be quickly moved in the direction of the arrow f, and the patient's body position can be changed from a vertical sitting position to a backward leaning position. It can be quickly adjusted to a horizontal position. Further, since each length of the first and second fluid pressure cylinders 42.47 is approximately twice the moving distance of the back plate 4 in the arrow f1f' direction, the first and second fluid pressure cylinders 42. 47
can be stored compactly between the angle adjustment plate 23 and the back plate base 27.

G. Next, according to FIGS. 5A and 5B, the back plate 3.
A modification of the forward/backward movement mechanism (double speed drive device) 41 of No. 4 will be described.

This modification includes a cylinder 45 which is the other end 42b of the first fluid pressure cylinder 42, and a cylinder 45 which is the other end 42b of the second fluid pressure cylinder 47.
A connecting member 59 is connected to the tip of the piston rod 50 which is 7b.
The other structures are connected directly by the fourth
It is the same as FIG. A and FIG. 4B. This modification also provides the same effects as in FIGS. 4A and 4B.

06 Next, according to FIGS. 6A to 8, the sewage receiving device 6
1 will be explained.

This sewage receiving device 61 has a pair of endless chains 62 mounted on both left and right sides of a seat plate base 36 so as to be horizontally rotatable via a pair of front and rear sprockets 63 and 64, respectively. In addition, a pair of guide shafts 6 are provided on both the left and right sides of the seat plate base 36.
5 is installed horizontally along the bottom of the cheno 62 on both ends. Parts of both end-end chains 62 are fixed with screws 67 or the like to the upper portions of a pair of left and right moving members 66 that are guided by these guide shafts 65 and moved horizontally. Then, by driving both sprockets 64 in forward and reverse rotation through a transmission member 69 and a drive shaft 70 by a driving means 68, which is a motor installed in the seat plate base 36, both end chinos 62 are driven. The re-moving member 66 is configured to be reciprocated along both guide shafts 65 in the directions of arrows c and c', which are the front and rear directions.

On the other hand, there are a pair of guides with a substantially U-shaped cross section on both the left and right sides of the sewage receiver 8, which is horizontally arranged at the bottom of the seat plate base 36.
a71 is integrally provided. Both guide grooves 71
The front end is formed as a closed end 71a, and the rear end is formed as an open end 71b.
is formed. A pair of left and right frictional engagement means 72 formed in a cylindrical shape or the like from synthetic resin or the like is mounted on a mounting shaft 74 to a bracket 73 fixed to the lower part of the removable member 66.
These frictional engagement means 72 are mounted horizontally by
are frictionally engaged with the guides a71 of the waste water receiver 8 so as to be relatively slidable therein. A pair of left and right stop levers 75 are attached to the side surfaces of both brackets 73 so as to be rotatable about a rotation fulcrum 76 in the up-down direction, ie, in the direction of arrow h. Both of these stop levers 75 are urged to rotate in the direction of the arrow by their own weight, and are integrally attached to the lower part of the rear end of both guide grooves 71 at the position where the knob 75a at the front end comes into contact with the lower part of the re-moving member 66. It is configured to be engaged with the protrusion 77 provided.

According to this sewage receiving device 61, as described above, both are activated by the driving means 68 which is activated at the same time as the placing part 1 is raised from the lowered position to the raised position or by an arbitrary switch operation by the doctor. When the end chino 62 is driven and the re-movement member 66 is moved forward in the direction of arrow C from the backward movement position shown by the point-by-point line in FIG. 6A to the forward movement position shown by the solid line, both frictional engagement means 72, the waste water receiver 8 is automatically pulled out in the direction of arrow C from the storage position shown by the dashed line in FIG. 6A to the pulled out position at the front lower part of the seat plate 2 shown by the solid line.

However, as shown in FIG. 6B, when the doctor pushes the front surface 8a of the wastewater receiver 8 pulled out to the pulled-out position with his/her hand in the direction of the arrow C' force, both frictional engagements in the side guide groove 71 occur. The member 6 re-moves the wastewater receiver 8 against the frictional engagement force of the coupling means 72.
6 (with the re-moving member 66 stopped at the forward movement position), the waste water receiver 8 can be freely and quickly pushed back by hand to any position in the force direction of arrow C'.

Therefore, when a patient's examination area is not cleaned during a medical examination or when the wastewater receiver 8 becomes an obstacle to the examination or medical treatment, the doctor can freely push back the wastewater receiver 8 automatically pulled out to the drawer position by hand as necessary. Therefore, the position of the waste water receiver 8 can be quickly changed by hand.

Note that when pulling out the sewage receiver 8, which has been pulled out to the pulled-out position shown by the solid line in FIG. 6A, from under the seat plate base 36 in the direction of arrow C, both stop levers 75 are moved in the direction of arrow h' using the knobs 75a. When rotated and removed above both protrusions 77, both frictional engagement means 72 can be easily pulled out from the opening @ 71b at the rear end of both guide grooves 71 by pulling the waste water receiver 8 in the direction of arrow C. I can do it.

G7 Next, the sewage scattering prevention device 81 will be explained with reference to FIGS. 6A and 6B.

This sewage scattering prevention device 81 is similar to the sewage receiving device 61 described above.
The sewage scattering prevention plate 9 placed on the upper part of the sewage receiver 8 is attached to the removable member 66 so as to be rotatable in the up and down directions of the arrows i and i' by means of a rotation fulcrum 82 which is a hinge, and is biased by a torsion spring. The means 83 biases the sewage scattering prevention plate 9 to rotate about the rotation fulcrum 82 in the direction of arrow i.

According to this sewage scattering prevention device 81, when both types of moving members 66 are moved back to the return position as shown by the dashed line in FIG. 6A, the sewage scattering prevention plate 9 resists the urging means 83. It is then rotated in the direction of the arrow i' and stored in a substantially horizontal position at the bottom of the seat plate base 36.

As described above, when the driving means 68 moves the two moving members 66 forward in the direction of arrow C from the backward movement position indicated by the dashed line in FIG. 6A to the forward movement position indicated by the solid line, the sewage receiver 8 and the sewage scatter The prevention plate 9 can be pulled out together with the prevention plate 9 in the direction of arrow C from the storage position indicated by the dashed-dotted line to the pulled-out position indicated by the solid line in FIG. 6A. At this time, the sewage scattering prevention plate 9 is pulled out in front of the seat plate base 36 and moved upward around the pivot point 83 by the biasing means 83 along the corner portion 36a at the lower front end of the seat plate base 36. It is rotated in a certain arrow i direction and gradually stands up. And the 6th. As shown by the solid line in Figure 1A, when this sewage scattering prevention plate 9 is completely pulled out to the drawn-out position, it stands up almost vertically above the sewage receiver 8, and as described above, it is placed above the seat plate 2. The lower part of the back plate 3, which is pulled out almost horizontally, is completely covered from the front. This vertically erected sewage scattering prevention plate 9 prevents sewage from scattering below the patient's seat (examination area) when cleaning the patient's examination area, and also prevents the sewage from scattering below the patient's seat (examination area). Functions as a blindfold.

According to this sewage scattering prevention plate 81, the back plate 3.4
The sewage receiver 8 and the sewage scattering prevention plate 9 can be pulled out together by the double moving member 66, which can be driven by the drive means 68 regardless of the backward tilt, etc. and the sewage scattering prevention plate 9 can be freely taken in and out together.

G. Next, Figure 1A, Figure 1B, Figures 9 to 10B

As described above, this material receiving device 86 is connected to the back plate base 26.
A pair of left and right material supports 6 are attached in parallel to a pair of left and right substantially L-shaped both-side frames 38 that are moved together with the frame. At this time, the both elbow lights 6 are configured as a member receiver 6 which also serves as an arm rest, with its upper horizontal surface serving as a light emitting surface 87 and its inner vertical surface serving as an upper limb rest surface 88 . A mounting base 90 is mounted on height adjustment sails 89 mounted on the side surfaces of both side frames 38 so as to be height adjustable in the direction of arrow j. Note that the mounting base 90 is attached to the height adjustment rail 8 by the groove 91.
9 is slidably fitted in the direction of arrow j, and a height adjustment screw 92 is attached to the side surface of the height adjustment screw 92 to be tightened and fixed at an arbitrary position on the side surface 89a of the height adjustment rail 89. Then, the inclined shaft 9 is inserted into the shaft mounting hole 93 provided in the mounting base 90.
4 is rotatably mounted around an axis P2 inclined at a predetermined angle θ4 with respect to a vertical reference line P1.

Note that the tip of a retaining screw 96 attached to the mounting base 90 is fitted into an annular groove 95 provided at the upper end of the inclined shaft 94. A mounting arm 103 fixed to the rear end of the material receiver 6 and bent in a substantially U-shape is fixed to the lower end surface 94a of the inclined shaft 94. A hole 97 with an axis P:l perpendicular to the axis P2 is formed in a part of the side surface of the inclined shaft 94.
A hole 98 having the same axis and the same diameter as this hole 97 is provided in the mounting base 90. and,
A lock pin 99 and a spring 100 are inserted into the hole 97,
A lock release pin 101 is inserted into the hole 98 and is movable in the direction indicated by the arrow. Note that the lock pin 99 is moved from the lock release pin 1 by the spring 100 in the direction of the arrow ''.
A retaining ring 102 is attached to the pin 101 which is pressed against the tip of the pin 101 to release the lock. Further, at the lower part of the mounting base 90, a rotation stop/two part 104 of the mounting arm 103 is provided.

According to this material receiving device 86, first, as shown in FIG. 1A, when the placing part 1 is lowered to the lowered position, the light emitting surface 87 of the both elbow lights 6 is locked upward and at a substantially horizontal upper end. There is. At this time, as shown in FIG. 10A, the lock pin 99 is fitted across both holes 97 and 98, and the inclined shaft 94 is locked with the lock pin 99.

Therefore, as described above, the patient who is in a vertical sitting position on the placement part 1 can stably place both elbows on the elbow receiving surfaces 87 of the elbow lights 6.

Next, as shown in Fig. 1B, when the patient's body position is adjusted to the horizontal position of the sitting posture by raising the placing part 1 to the raised position and tilting it backward, both elbow lights 6 are placed at one point in Fig. 1B. It stands up almost vertically as shown by the chain line. Therefore, as shown in FIG. 10B, the lock release bottle 101 is slightly pushed in the direction of the arrow, and the lock bottle 99 is completely pushed into the hole 97 against the spring 100 to release the lock of the tilting shaft 94. 6 is attached to the tilting shaft 9 integrally with the mounting arm 103 and the tilting shaft 94.
4, an arrow points outward from the mounting section 1 from the position of the solid line to the position of the dashed-dotted line in FIGS. 9 and 10B. The mounting arm 103 is brought into contact with the rotation stopper 104 by rotating approximately 90° in the direction of the mounting arm 103 . Then, as shown in FIG. 1B, the elbow lights 6 are laid down on both left and right sides of the placement part 1 in a substantially V-shape, and the upper limb platform 8 of the elbow lights 6 is lowered.
8 is turned upward and almost horizontally, and at this point,
Both elbow lights 6 are changed into arm rests.

Therefore, both upper limbs of a patient whose body position has been adjusted to the horizontal position of a sitting position on the placing unit 1 can be stably placed almost horizontally on the upper limb table 88 of the both elbow lights 6, and emergency blood transfusion of the patient can be performed. can be done quickly.

Note that when the arm light 6 is rotated together with the mounting arm 103 and the tilting shaft 94 in the direction of arrow β' and returned to its original position, the lock bin 99 is automatically moved to the locked state shown in FIG. 10A by the spring 100. The moment the both elbow lights 6 return to their original positions, they are automatically locked.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various effective changes can be made based on the technical idea of the present invention.

H Effects of the Invention Since the present invention is configured as described above, it produces the following effects.

The mounting part can be quickly moved relative to the base at double the speed of the fluid pressure cylinder, so in the event of emergency bleeding, etc., the patient's body position can be quickly adjusted from a sitting vertical position to a horizontal position leaning backwards. This allows for easy examination and treatment in emergencies.

Since the length of each of the two hydraulic cylinders can be reduced to approximately twice the travel distance of the receiver, it is possible to connect the two hydraulic cylinders with a small mounting space, especially when the travel distance of the receiver is long. It can be stored compactly in one space, making it possible to downsize the medical table.
