Description

  The present invention relates to an examination table on which a person to be examined is placed in a medical field.

  Conventionally, when a person to be examined is examined at a medical facility, the person to be examined is placed on an examination table. Such an examination table has, for example, a foot plate on which a foot is placed horizontally formed, a foot plate whose tip can be bent upward, and a so-called counter-type portion for dental use where a leg is placed bent downward. There are things.

  For example, in the case of a pregnant woman examination, the examination table in which the footboard is formed horizontally takes a posture where the examinee bends the knee, puts a calf on the support leg, and is in a crushed stone position. In addition, the examination table in which the tip of the foot plate is bent upward can stabilize the crushed stone position because the examinee's heel can be placed using the tip of the foot plate as a support. Furthermore, the counter type examination table is easy to get on and off the examinee because the part on which the leg is placed is bent downward.

  When the footboard of the examination table is horizontal, the examinee is burdened when getting on and off. In particular, the burden is high when the examinee is a pregnant woman, and the crushed stone position becomes unstable. In addition, in the case of the counter type, since the portion on which the leg is placed is bent downward, the crushed stone posture is difficult.

  In the case where the tip of the foot plate can be bent upward, for example, there is one described in Patent Document 1 below. In this examination table, leg placing parts on which the legs are placed are formed on both the front side and the back side, and the leg placing parts are inverted, so that the shape is deformed according to the posture of the examinee to be placed. That is, a flat part is formed on the front side and the leg is extended, and a sole receiving part inclined from the flat part is formed on the back side, and the back of the leg is placed with the knee bent.

  As described above, the examination table 10 according to the present embodiment is configured.

  Next, the operation of the examination table 10 according to the present embodiment will be described.

  As shown in FIG. 6, in the getting-on / off type 1, the cylinder 21 is driven, and the piston is pushed forward with respect to the cylinder 21, so that the driving link member 17 is pushed by the piston to move the driving link shaft portion 22. Rotate to axis. Along with this, the third mounting portion 16 is rotated by the driving link member 17 and the interlocking link member 18, and the front end rises. Since the second mounting portion 15 pivotally supported by the first joint shaft portion 19 is connected to the second joint shaft portion 20 and the long hole 25 of the second mounting portion 15, the second joint shaft portion 20. With the movement, the first joint shaft portion 19 is rotated about the axis. At that time, the third placement portion 16 is arranged to rotate about the first joint shaft portion 19 by the driving link member 17 and the interlocking link member 18, and the second placement portion 15 and the third placement portion 16. The second joint shaft portion 20 is disposed so that the placement portion 16 is substantially in the same plane. In this way, the second placement portion 15 and the third placement portion 16 are disposed on substantially the same plane as the first placement portion 14 and become substantially transversal with respect to the installation surface to form the transabdominal mold 2. Deform.

  With the transformation from the getting-on / off type 1 to the transabdominal type 2, the examination table 10 rises and the backrest 12 tilts backward, and the posture of the examinee 10 naturally changes from the sitting position to the back (FIG. 4). reference).

  As shown in FIG. 6, in the transabdominal mold 2, the cylinder 21 is further driven, and the piston is pushed further forward with respect to the cylinder 21, whereby the driving link member 17 is pushed by the piston and the driving link shaft The portion 22 is further rotated around the axis. Along with this, the third mounting portion 16 is rotated by the driving link member 17 and the interlocking link member 18, and the front end is further raised. Since the second mounting portion 15 pivotally supported by the first joint shaft portion 19 is connected to the second joint shaft portion 20 and the long hole 25 of the second mounting portion 15, the second joint shaft portion 20. With the movement, the first joint shaft portion 19 is rotated about the axis. At that time, the third mounting portion 16 is rotated about the second joint shaft portion 20 by the driving link member 17 and the interlocking link member 18, and the second joint shaft portion 20 is held substantially horizontally. Are arranged as follows. At this time, the second joint shaft portion 20 moves back and forth along the long hole 25 of the second placement portion 15. That is, since the movement of the second mounting portion 15 pivotally supported by the first joint shaft portion 19 is determined by the position of the second joint shaft portion 20, the first mounting portion 14 and the first mounting portion 14 are substantially horizontal during this time. State is maintained. In this way, the second placement portion 15 is maintained while being arranged in a substantially flush state with the first placement portion 14, and the third placement portion 16 is positioned above the second placement portion 15. Inclined to deform to transvaginal type 3.

  With the transformation from the transabdominal type 2 to the transvaginal type 3, the examination table 10 further rises and the lower limb placement parts 13 are separated from each other, and the posture of the examinee naturally changes from the supine position to the crushed stone position. To do.

  By going through the reverse procedure to the above, the vaginal mold 3 is transformed into the boarding / leaving mold 1 through the transabdominal mold 2 (see FIG. 4).

  Next, the effect of the examination table 10 according to the embodiment of the present invention will be described.

  As described above, according to the examination table 10 according to the present embodiment, the link mechanism uses the first mounting portion 14 as a fixed link, and is a link connected to the first mounting portion 14 and the third mounting portion 16. It is comprised from the drive link member 17 and the interlocking link member 18 as a member, and the cylinder 21 which operates a link mechanism. In the link mechanism, the first mounting portion 14 and the second mounting portion 15 are connected to form the first joint shaft portion 19, and the second mounting portion 15 and the third mounting portion 16 are connected to each other. A second joint shaft portion 20 is formed.

  According to this configuration, the front end of the driving link member 17 rises when the rear end side is pushed by the cylinder 21, and the front end of the third mounting portion 16 rises following this. In the deformation from the getting-on / off type 1 to the trans-abdominal type 2, the second placement part 15 and the third placement part 16 are arranged on substantially the same plane as the first placement part 14, and are almost the same as the installation surface. Become horizontal. In the transformation from the transabdominal mold 2 to the transvaginal mold 3, the second mounting portion 15 is maintained while being arranged in a substantially flush state with the first mounting portion 14. On the other hand, the third mounting portion 16 is inclined upward.

  That is, the drive source for operating the first joint shaft portion 19 and the second joint shaft portion 20 is a single cylinder 21, and the cylinder 21 is driven to drive the first placement through the link members 17 and 18. The angle of the second mounting part 15 with respect to the part 14 and the angle of the third mounting part 16 with respect to the second mounting part 15 change. Therefore, since the two joint shaft portions 19 and 20 operate with one cylinder 21, the configuration is simple. In addition, the design can be selected, and the cost can be reduced. Furthermore, depending on the time of getting on and off and at the time of medical examination, it changes to a boarding type 1, a transabdominal type 2 and a transvaginal type 3, respectively, and it is possible to naturally encourage the examinee to have a suitable posture at the time of getting on and off and medical examination.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims. For example, when the examinee is a pregnant woman, there is a concern about a mechanical mechanism having a feeling of mental pressure, so the driving means may be a manual type.
