Description

[Detailed description of the invention] Industrial application field The present invention is an incubator equipped with various equipment such as a treatment device and a monitoring device used when treating or monitoring premature infants housed in an incubator. The present invention relates to a safety device for an incubator stand to be installed near an incubator stand.

BACKGROUND TECHNOLOGY AND PROBLEMS Traditionally, various devices such as treatment devices and monitoring devices necessary for treating or monitoring premature infants housed in incubators have been placed near the incubators by attaching them to the shelves or supports of stands. The installation method is very advantageous in terms of effective use of these various devices.

However, when the above-mentioned devices are attached to the shelves and supports of the stand, a considerable load will be placed on the stand. If the stand is placed in a high position, such as above the shelf, and the various devices mentioned above are placed on the shelf, the center of gravity of the stand becomes high, making it easy for the stand to topple over.

In addition, if a shelf is placed above the incubator as described above, the shelf will get in the way when observing a premature baby in the incubator from above or taking X-rays from above. It would be very convenient to slide this shelf backwards, etc., but if you slide the shelf while the various devices mentioned above are placed on the shelf, the balance of the center of gravity of the stand will be affected. The stand collapses and easily falls over, posing a great risk of damaging various expensive equipment or causing injury.

Purpose of the invention The present invention aims to provide a safety device for an incubator stand that can solve the above-mentioned problems all at once.

Summary of the invention The present invention includes a sliding shelf disposed above the incubator, a locking means for locking the sliding shelf in a fixed position, and a coupling means that can be connected to and separated from the incubator. The incubator stand is provided with an incubator stand, wherein when the incubator is coupled to the stand and the coupling means is in the coupled state, the locking state of the sliding shelf by the locking means is released and the sliding shelf is moved. This is a safety device for an incubator stand configured to allow sliding of the shelf.

Next, as shown in FIGS. 1 and 3, a pair of left and right release levers 43 are arranged on the upper part of the intermediate frame 14 of the stand 10. Both release levers 43 have their rear ends fixed to both ends of a connecting shaft 44, and are rotatably supported by the connecting shaft 44 on a pair of bearing brackets 45 fixed on the intermediate frame 14. . Both release levers 4
A pair of handles 46 are attached to the front end of the handle 3 via attachment pins 47. The lower ends of a pair of interlocking levers 48 are pivotally supported by both mounting pins 47, and both interlocking levers 48 are connected to the fifth
As shown in the figure, these small rods 37 are engaged with the rear ends of both small rods 37 by means of protrusions 49 integrally provided at their upper ends.

The stand 10 of the present invention is constructed as described above, and is coupled and separated from the incubator 1 in the following manner.

First, as shown in FIGS. 1, 3, and 5, when the stand 10 is separated from the incubator 1, the lower ends of both rods 20 are rotated in the direction of arrow a by both compression springs 40. Both coupling fittings 30 are placed on both locking pieces 34 under force. At this time, as shown in FIG. 5, both rods 20 come into contact with the front ends of the rod insertion holes 24, and their rotation in the direction of arrow a is restricted. Also, at this time, both rods 20 are raised in the direction of arrow b against both compression springs 26, and the upper ends 20a of the sliding shelves are moved back to the home position as shown in FIGS. 1 and 3. 16 in both locking holes 27 to lock the sliding shelf 16 in place. Therefore, in this state, the sliding shelf 16 is unable to slide, and the sliding shelf 16 unexpectedly slides to the rear sliding position shown by the imaginary line in FIGS. 2 and 4, causing the balance of the center of gravity of the stand 10 There is no danger of the stand 10 collapsing and falling over.

Next, as shown in FIGS. 2, 4, and 6, when the incubator 1 is inserted into the stand 10 from the direction of arrow c, the mounting pins 7 on the rear end side of the handles 6 on both sides of the incubator 1 10, and presses it in the direction of arrow c. Then, the lower ends of both rods 20 are connected to both compression springs 4.
0 in the direction of arrow a', both coupling fittings 30 come off at their notches 33 toward the rear side of both locking pieces 34. At that moment, both rods 20 are lowered in the direction of arrow b' by both compression springs 26, and the recesses 31 of both coupling fittings 30 are engaged with both mounting pins 7 from above. At this time, as shown in FIG. 6, both small rods 37 come into contact with the lower ends of the rod insertion holes 39, and the descending height of both rods 20 in the direction of arrow b' is regulated. At the same time, the incubator 1 is brought into contact with both stoppers 17 and the stand 10
The incubator 1 is positioned within the incubator.

As a result of the above, both coupling fittings 30 lock both mounting pins 7 through both recesses 31, and the lower ends 20b of both rods 20 are attached to rear end surfaces 34a of both locking pieces 34 by both compression springs 40. When the two rods 20 are pressed against each other, they cannot move forward or backward, and the incubator 1 and the stand 10 are integrally connected.

In short, simply by inserting the incubator 1 into the stand 10 in the direction of arrow c and bringing it into contact with both stoppers 17, the incubator 1 and the stand can be automatically coupled. Due to this connection, the sliding shelf 16 is placed above the hood 3 of the incubator 1, and the phototherapy device attached to the lower part of the sliding shelf 16 can perform phototherapy on the premature infant in the hood 3. becomes. In addition, in this combined state, the stand 10 is integrated with the incubator 1, and these casters 1
2 and 5, it can be moved freely.

By the way, when the incubator 1 and the stand 10 are connected as described above, the upper end portions 20a of the rods 20 are moved downward by the compression springs 26 in the direction of arrow b' as described above. Both locking pieces 27 of the sliding shelf 16 are released below, and the locking of the sliding shelf 16 in its normal position is automatically released. Therefore, in this coupled state, the sliding shelf 16 can be freely slid to the rear sliding position shown by the imaginary line in FIGS. When taking X-rays from above,
The sliding shelf 16 can be freely slid to the rear sliding position so as not to interfere with these. Note that when the incubator 1 and stand 10 are combined,
The weight of the incubator 1 completely prevents the stand 10 from falling over. Therefore, even if the sliding shelf 16 is slid to the rear sliding position, there is no possibility that the stand 10 will accidentally fall over.

Next, when the incubator 1 is to be separated from the stand 10, the sliding shelf 16 is first moved back to the home position shown by the solid line in FIG. Next, as shown by the imaginary line in FIG. 4, one of the handles 46 is grasped and one of the release levers 43 is rotated in the direction of arrow d. Then, the other release lever 43 is also rotated together in the same direction via the connecting shaft 44, and both interlocking levers 48 are lifted in the direction of arrow e. Then, both rods 20 are lifted in the direction of arrow b through both small rods 37 by the projections 49 of both interlocking levers 48 against both tension springs 26. As a result, the recesses 31 of both coupling fittings 30 are removed above the mounting pins 7 of the incubator 1, and the state of coupling between the incubator 1 and the stand 10 is released.

At this time, by lifting both rods 20, their upper ends 20a are inserted into both locking holes 27 of the sliding shelf 16, as shown in FIG. 3, and the sliding shelf 16 is locked in the normal position again. In addition, by lifting both rods 20, both coupling fittings 30 are pulled up above both locking pieces 34 at the notch 33 portion, and at that moment, the lower ends of both rods 20 are moved in the direction of arrow a by both compression springs 40. After being rotated, both coupling fittings 3
0 is again placed on both locking pieces 34 as shown in FIG.

After the above, move the incubator 1 to the first position from inside the stand 10.
It can be freely separated in the forward direction, which is the direction of arrow c' in FIGS.
