2. Explanation of the bed base

As shown in FIGS. 4 to 6, the bed 5 in the first embodiment includes a bed type main body 61 having a substantially basin shape which may be substantially rectangular in plan view, and the bed bed main body 61. A pair of left and right long side guard members 62a and 62b and a pair of front and rear short side guard members 63a and 63b, which are detachably attached, are provided. The bed base body 61 is disposed on the bed base (in other words, the bed base tray) 4. Then, the floor rack 4 is arranged on the base 2 via a support mechanism (not shown) for the floor rack. Specifically, as shown in FIGS. 4 and 4A, a concave portion 64 having a partial substantially cylindrical surface shape is provided on the upper surface of the base 2. And the bottom floor 4 is provided with a bottom surface portion 65 having a protrusion 65a substantially corresponding to the concave portion 64 at a substantially central portion in the width direction. Further, the bottom surface portion 65 (and thus the protrusion 65a) has a partial cylindrical surface shape. When the operator rotates the operation dial 66 (see FIG. 1) clockwise or counterclockwise, the bed support mechanism moves the head 71 of the child 7 upward or downward. For this reason, it is possible to swing the floor rack 4 (and thus the floor base body 61) back and forth.

  4 and 4A, a pair of front and rear guide rail portions 72a and 72b for reciprocating the bed base main body 61 in the left-right direction (in other words, the width direction) are provided on the bed rack 4. ing. The bed base body 61 is provided with a pair of front and rear guided protrusions 73a and 73b corresponding to the pair of front and rear guide rail portions 72a and 72b, respectively. Each of the guide rail portions 72a and 72b has a longitudinal recess 74 extending substantially in the left-right direction, and prevents the guided ribs 73a and 73b from coming out of the longitudinal recess 74. And a pair of left and right protrusions 75 for preventing slipping. For this purpose, each of the guided protrusions 73a and 73b is provided with a protrusion 76 for engagement that can be engaged with the protrusion 75 for retaining. Then, the bed base body 61 is not displaced with respect to the bed base 4 in the left-right direction (in other words, the center line in the width direction of the bed base body 61 is seen in a plan view, and the bed base 4 In the state substantially coincident with the center line in the width direction, the retaining projection 75 is positioned between the pair of left and right engaged projections 76 in plan view. For this reason, when trying to lift the bed base body 61 from the bed 4, the pair of left and right engaged projections 76 move substantially upward without coming into contact with the retaining projection 75. The protruding portions 73a and 73b can be detached from the guide rail portions 72a and 72b, respectively. However, when the bed base body 61 moves to some extent in either of the left and right directions with respect to the bed base 4, a pair of left and right sides may be lifted even if the bed base body 61 is lifted from the bed base 4. Since any one of the engaged protrusions 76 contacts the retaining protrusion 75 as a stopper, the protrusions 73a and 73b cannot be detached from the guide rails 72a and 72b. Further, when the bed base body 61 is to be moved largely in any one of the left and right directions with respect to the bed base 4, the bed base body 61 abuts against a stopper (not shown) of the bed base 4. Therefore, the movement of the bed base body 61 is prevented from being moved more than necessary in the left-right direction.

  As shown in FIG. 4, the cassette tray storage space 50 includes a substantially horizontal plate-like portion 77 of the bed base body 61, a pair of front and rear ridges 73 a and 73 b of the bed base body 61, and the bed base 4. It is composed of enclosed space. In the vicinity of both front and rear end portions of the upper surface portion of the cassette tray 54, engaging protrusions 81 that protrude in a substantially horizontal state toward the front and the rear are formed. In addition, a pair of front and rear supporting protrusions 82 are formed on the protrusions 73 a and 73 b of the bed base body 61. Each of the pair of front and rear engaging protrusions 81 is placed on the pair of front and rear supporting protrusions 82, so that the cassette tray 54 is placed on the lower surface of the plate-like portion 77 of the bed base body 61. It is supported by the bed base body 61 in an adjacent state. Further, when the cassette tray 54 is to be taken out of the cassette tray storage space 50, the operator opens the opening / closing door 49 of the left wall portion or the right wall portion 13 of the base 2, and then the cassette tray 54. It is only necessary to hold the handle 83 and pull it out. Further, when it is desired to mount the cassette tray 54 in the cassette tray storage space 50, an operation reverse to that in the above-described removal may be performed. For example, an X-ray imaging film (not shown) can be placed on the cassette tray 54. The film can be used for X-ray imaging of a part of the body of the child 7.

  As shown in FIG. 5, the plate-like portion 77 of the bed base main body 61 includes a relatively thin plate-like portion main body 84 which may be substantially rectangular, and a plate projecting upward from the plate-like portion main body 84. It may consist of a relatively thick frame portion 85 that extends along the outer periphery of the shaped body 84 and may be a substantially rectangular frame shape. A front attachment hole 91 and a rear attachment hole 92 are respectively provided in the frame piece portion 86a on the long side on the left side of the frame portion 85. Further, a front side mounting hole 93 and a rear side mounting hole 94 are respectively provided in the frame piece portion 86b on the long side on the right side of the frame portion 85. Further, a left side mounting hole 96 and a right side mounting hole 97 are respectively provided in the frame piece portion 95a on the short side on the front side (in other words, on the tip end side) of the frame portion 85. Also, a left side mounting hole 98 and a right side mounting hole 99 are respectively provided in the frame piece portion 95b on the short side on the rear side (in other words, on the base end side) of the frame portion 85. The specific shapes and the like of each of the mounting holes 91 to 99 are the following item (that is, “3, description of the short side guard member”) and the next item (that is, “4, description of the long side guard member”). ). And the attachment hole 100 for tube holder attachment is formed in the four corner vicinity of the frame part 85, respectively. Moreover, the base end part of a tube holder can be attached to these attachment holes 100 by insertion as needed.

As shown in FIG. 21, each of the end faces substantially abuts on the front end face of the attachment hole 91 and the rear end face of the attachment hole 94. Therefore, the left and right long-side guard members 131a and 131b are securely held on the bed base main body 61 in the front-rear direction and the left-right direction, respectively, so that the left and right long-side guard members 131a and 131b are attached to the bed base main body 61 in a satisfactory manner. However, the rear end surface of the attached portion 144 of the attached member 146 on the front side of the left long side guard member 131a and the front end surface of the attached portion 144 of the attached member 147 on the rear side of the right long side guard member 131b. Each has a gap 151 having a length L _{15 from} the rear end surface of the attachment hole 91 and the front end surface of the attachment hole 94. The reason for this is as shown in FIG.
(A) the length L ₅ and the length L ₆ are substantially the same size;
(B) nearly by a length _{L 15} smaller than the length _{L 13} is the length _{L 2,}
It is.

  When removing each of the long side guard members 131a and 131b shown in FIG. 19 and the like from the bed base body 61, the handler grasps the middle portion of each of the long side guard members 131a and 131b in the left-right direction with one hand or the like. From here, it can be lifted almost upward. In this case, each of the attached portions 144 comes out of the attachment holes 91 to 94 relatively easily, so that each of the long side guard members 131a and 131b can be removed from the bed base main body 61 relatively easily. According to the long side guard members 131a and 131b configured as described above, the left side edge and the right side edge of the bed base body 61 are relatively long and relatively high in height. High guards (so-called baby guards) or fences can be detachably (in other words, freely removable).

(3) Third type long side guard member

  As shown in FIGS. 23 and 24, the third type of long side guard member 151 includes a substantially arch-shaped guard member main body 152 and a long side guard member 151 (in other words, the guard member main body 152). It comprises a pair of front and rear attached members 146 and 147 for attaching the left and right side end portions to a pair of front and rear attachment holes 91 to 94 of the bed base main body 61, respectively. In short, the third type of long side guard member 151 is a pair of left and right guard members of a pair of left and right long side guard members 131a and 131b shown in FIGS. 18 and 19, respectively. The main body 140 may have a shape that is integrally connected so as to have an almost arch shape as a whole. And the substantially arch-shaped guard member main body 152 of the long side guard member 151 may be integrally formed from a synthetic resin. Further, the left half and the right half of the long side guard member 151 may have substantially symmetrical shapes. Further, the third-type long-side guard member 151 includes the pair of left and right second-type long-side guard members 131a and 131b as a whole, except for the points described below, unless otherwise inconsistent. It may have substantially the same configuration as that integrally connected so as to have a substantially arch shape and exhibit substantially the same operational effects. The bed base body 61 to which the third type long side guard member 151a is attached is the same as the bed base body 61 to which the pair of left and right second type long side guard members 62a and 62b are respectively attached. It may be.

  In the case where the long side guard member 151 configured as described above is normally attached to the bed base body 61, as shown in FIG. 24, the radiant heat radiated from the child on the bed base body 61 is an arch-shaped guard. The member body 152 is shielded to a considerable extent. For this reason, since the fall of a child's body temperature can be suppressed considerably, there is little possibility that the body temperature of the child 7 will fall rapidly. Furthermore, even when the temperature outside the enclosure 3 of the incubator 1 is relatively low, the body temperature of the child 7 laid on the bed base body 61 is lowered by the radiant heat of such relatively low outside air. The guard member main body 152 can be considerably suppressed.

5. Explanation of wrong mounting operation of guard member

  Four types of examples of the erroneous mounting operation of the guard members 62a, 62b, 63a, 63b, 101a, 101b, 102a, 102b, 131a, 131b, 151 with respect to the bed base body 61 are described in “(1) First type of error”. "Mounting operation", "(2) Second type of erroneous mounting operation", "(3) Third type of erroneous mounting operation", "(4) Fourth type of erroneous mounting operation" These will be described with reference to FIGS. 11 to 13 and FIG. 14, respectively.

(1) The first type of mismounting operation

As shown in FIG. 11, the first type of erroneous mounting operation is a long-side guard member in a pair of left and right mounting holes 96, 97 disposed in the short-side frame piece 95 a on the front side of the bed base body 61. This is a case where an operation of attaching a pair of front and rear attached portions 134 and 135 of 62a is performed. In this case, the pair of left and right attached portions 134 and 135 are fitted into the pair of left and right attachment holes 96 and 97, respectively. However, which is slightly smaller than the length L ₄ from the upper end of the erroneous mounting prevention spigot 138 to the recess 115 of the cutout shape from the upper end of the hole 96 and 97 mounted the length L ₁₀ to the stepped portion 141. For this reason, the stepped portion 141 is not temporarily locked in the notch-shaped concave portion 115 in a temporarily locked state, so that the operator sensuously recognizes that the erroneous mounting operation is being performed by hand or the like. be able to.

(2) Second type of mismounting operation

As shown in FIG. 12, the second type of erroneous mounting operation is performed by a short-side guard member in a pair of front and rear attachment holes 91 and 92 disposed in the long-side frame piece 86a on the left side of the bed base body 61. This is a case where an operation of attaching the pair of left and right attached parts 104 and 105 of 63a is attempted. In this case, the length L ₂ in a substantially horizontal direction of the front of the mounting hole 91, because it is approximately the same length as the length L ₁ in the substantially horizontal direction of the mounting portion 104, the mounting portion 104, the front The mounting hole 91 is theoretically fitted. However, the length L ₁₂ of the rear mounting hole 92 in the substantially horizontal direction is slightly smaller than the length L ₁ of the mounted portion 105 in the substantially horizontal direction. For this reason, the positioning insertion portion 106a comes into contact with the long-side frame piece 86a (specifically, the vicinity of the rear mounting hole 92) of the bed base main body 61. Accordingly, the handler cannot clearly fit the attachment portion 105 into the attachment hole 92 on the rear side, and can clearly recognize that an erroneous attachment operation is being performed. Note that the above situation is caused by the pair of left and right attached portions 104 and 105 of the short side guard member 101a shown in FIG. 14 and the short side guard member 102a shown in FIG. This also occurs when an incorrect mounting operation is performed to fit each of 92.

(3) Third type of mismounting operation

As shown in FIG. 13, the third type of erroneous mounting operation is performed on the left long side of the pair of front and rear mounting holes 91 and 92 disposed in the left long frame piece 86a of the bed base body 61. This is a case where an operation for attaching the pair of front and rear attached portions 134 and 135 of the guard member 62a is performed, and in particular, the outer side surface and the inner side surface of the long side guard member 62a are attached to be opposite to each other. This is the case. In this case, since the length L ₂ in the substantially horizontal direction of the front attachment hole 91 is larger than the length L ₁₃ in the substantially horizontal direction of the attachment portion 135, the attachment portion 135 is theoretically connected to the front attachment hole 91. It fits. However, the length L ₁₂ in the substantially horizontal direction of the mounting hole 92 of the rear side is somewhat smaller than the length L ₁ in the substantially horizontal direction of the mounting portion 134. For this purpose, the positioning insertion portion 137b contacts the long side frame piece 86a (specifically, the vicinity of the rear mounting hole 92) of the bed base body 61. Therefore, the handler cannot clearly fit the attachment portion 134 into the attachment hole 92 on the rear side, and can clearly recognize that an erroneous attachment operation is being performed.

(4) Fourth type of mismounting operation

  As shown in FIG. 22, the fourth type of erroneous mounting operation is performed on the left side shown in FIG. 18 in a pair of left and right mounting holes 96, 97 arranged in the short side frame piece 95 a on the front side of the bed base body 61. This is a case where an operation of attaching the pair of attached portions 146 and 147 of the long side guard member 131a is performed. In this case, the pair of left and right attached portions 146 and 147 fits well into the pair of left and right attachment holes 96 and 97, respectively. However, since the length of the long side guard member 131a is sufficiently longer than the length of the short side frame piece portion 95a, both ends of the long side guard member 131a are respectively separated from the left and right sides of the bed base body 61. It is attached to the bed base main body 61 in a state protruding in the direction. For this reason, the handler can easily and clearly recognize that the long side guard member 131a is not attached to the normal attachment position.

  The above situation also occurs due to an erroneous mounting operation in which the pair of front and rear attached portions 146 and 147 of the long-side guard member 132 shown in FIG. 23 is fitted into the pair of left and right attachment holes 96 and 97, respectively. In this case, the original width in the left-right direction of the long-side guard member 132 (in other words, the distance between the left-side long-side frame piece portion 86a and the right-side long-side frame piece portion 86b) is the bed base. It is sufficiently smaller than the length of the main body 61 in the front-rear direction (in other words, the distance between the front short-side frame piece 95a and the rear short-side frame piece 95b). For this reason, the handler can easily and clearly recognize that the long side guard member 132 is not attached to the normal attachment position.

6. Description of the embodiment of the bed base

As the short side guard member, as described in the third item (that is, the item “3, description of the short side guard member”), the first type short side guard members 63a, 63b, Two types of short-side guard members 101a and 101b and a third type of short-side guard members 102a and 102b are prepared. As the long side guard member, the first type long side guard members 62a and 62b as described in the fourth item (that is, the section of “4, description of the long side guard member”) are used. The second type long side guard members 131a and 131b and the third type long side guard member 132 are prepared. Therefore, the same kind of guard member is used as the front short side guard member and the rear short side guard member, and the same kind of guard member is used as the left long side guard member and the right long side guard member.

  However, it is not always necessary to use the same kind of guard members as the front short side guard member and the rear short side guard member. In addition, it is not always necessary to use the same kind of guard member as the left long side guard member and the right long side guard member. Therefore, if three types of short-side guard members and three types of long-side guard members are prepared as in the illustrated embodiment, the embodiment of the bed 5 is much larger than the above nine types. Embodiments can be realized.
