Description

  The present invention relates to an examination table used when a examiner examines a patient while grasping an examination instrument such as a probe of an ultrasonic diagnostic apparatus, for example.

  For example, when a medical examiner examines a patient while holding a medical examination device such as a probe of an ultrasonic diagnostic apparatus (hereinafter referred to as “ultrasonic probe”), a medical examination table designed for medical examination. Is usually used.

  As an example of a conventional examination table, for example, in Patent Document 1, the drop part is rotated downward so as to be retracted from the examination table surface so that the body part such as the chest, abdomen, or back of the patient can be exposed. An examination table for ultrasonic diagnosis is disclosed that reduces the burden associated with the change of the patient's position and improves the efficiency of the examination.

However, in the case of ultrasonic diagnosis, the examiner grasps the ultrasonic probe with one hand and explores the required part of the patient's body over a long period of time. It has been pointed out that the efficiency and accuracy of the patient are reduced, and as a result, tendonitis is suffered. Such a problem is not limited to the above-described example of ultrasonic diagnosis. Therefore, when the examiner performs the examination of the patient while holding the examination device for a relatively long time, there is a strong social demand to take some measures to reduce the burden on the examiner. .

FIG. 4 is an explanatory perspective view of a main part showing a state in which the upper surface is raised to a lifting position where it is flush with the upper surface of the reclining unit, FIG. 4 is an exploded front view showing a lifting mechanism for driving the pocket part up and down, and FIG. FIG. 6 is a front view illustrating a main part of the lifting mechanism in a state where the pocket part is raised, FIG. 6 is a front view illustrating a main part of the lifting mechanism in a state where the pocket part is lowered, and FIG. FIG. 8 is a front view of a main part of the reclining unit, and FIG. 9 is a cross-sectional view taken along the line AA of the reclining unit shown in FIG. 8.

  As illustrated in FIG. 1, the examination table 11 according to the first embodiment includes a bed 13 on which a patient can lie down at the time of examination, and a support 15 that supports the bed 13 from below.

  As shown in FIG. 1, the bed 13 includes a flat portion 17 and a reclining portion 19 that is pivotally supported on the free end side 17 a of the flat portion 17. In the normal use state of the bed 13, the lower body of the patient is positioned on the flat portion 17 side, while the upper body of the patient is positioned on the reclining portion 19 side. In addition, as shown in FIG. 1, the reclining unit 19 is provided with a posture holding grip 20 for guiding the right hand of a patient who is lying on the bed 13 to receive a medical examination in the left-side position.

  As shown in FIGS. 1 to 3 and 8, the reclining unit 19 that constitutes a part of the bed 13 includes a reclining unit 19 (the bed) for supporting the examiner's body, in particular, for example, an arm. 13) and provided separately. This pocket part 21 is provided in the reclining part 19 (bed 13) in the position which faces the medical examination location of the patient who is lying down at the time of medical examination, for example, a chest. The pocket portion 21 is supported through a lifting mechanism 30, which will be described later, provided on the support body 15 in a stepless and adjustable manner at a required lifting position in a state where the posture is maintained substantially horizontal. As a result, for example, when a medical examiner performs a medical examination while holding a medical examination instrument for a relatively long time, the medical examination person appropriately adjusts the raising / lowering position of the pocket portion 21 to grasp the medical examination instrument. By supporting his / her own arm in the pocket portion 21 whose position has been adjusted, the examination can be performed in a state where the arm is released from the weight of the examination instrument.

  Moreover, as shown in FIGS. 1-3 and 8 in the reclining part 19, the backrest part 23 for supporting a patient's back is provided separately from the reclining part 19 (bed 13). The backrest 23 is pivotally supported by the support 15 and is supported by a support mechanism 40 (described later) provided on the support 15 so as to be positioned and adjustable at a required undulation position.

  Now, as shown in FIG. 1, the bed 13 is supported by leg portions 25 constituting a part of the support 15. The bed 13 is supported at a required lift position in a stepless manner through a support lifting mechanism (not shown) built in the leg portion 25 in a stepless manner. Thereby, for example, it is possible to facilitate getting on and off the examination table 11 of a physically handicapped patient or a pediatric patient. The leg 25 is supported by a leg frame 19 made of, for example, an H-shaped steel material, and casters 29 for making the examination table 11 movable are provided at four corners of the leg frame 27, respectively.

  By the way, as shown in FIG. 4, the elevating mechanism 30 that can elevate the pocket portion 21 in a state where the posture thereof is maintained substantially horizontal mainly includes the first and second torque arms 31 and 32 and the connecting member 33. And an electric actuator 34.

  The first and second torque arms 31 and 32 have substantially the same shape, and in the first embodiment, two each, for convenience, four are used.

First torque arm 31 is, for example, as shown in FIGS. 4 and 7, the folding of the first end portion 31r of the first arm 31a which is formed into a substantially L-shaped, first as arm linearly formed One end of the link 31b is integrally connected at a predetermined angle θ via a continuous rod 37.

On the other hand, as shown in FIGS. 4 and 7, for example, the second torque arm 32 is an arm formed in a straight line at the second end portion 32r on the folding side of the second arm 32a formed in an approximately L shape . One end of the second link 32b is integrally connected at a predetermined angle θ through the linkage 38.

  Further, as shown in FIG. 4, the free end side 31 j of the first arm 31 a in the first torque arm 31 can be rotated to the first connecting portion 22 j of the pocket frame 22 attached to the lower surface of the pocket portion 21. The free end side 31k of the first link 31b is rotatably connected to the first connecting portion 33k of the connecting member 33.

  Similarly, as shown in FIG. 4, the free end side 32n of the second arm 32a in the second torque arm 32 is rotatably connected to the second connecting portion 22n of the pocket frame 22, and the free of the second link 32b. The end side 32m is rotatably connected to the second connecting portion 33m of the connecting member 33.

  Further, as shown in FIGS. 4 and 7, the linkage 37 is rotatably connected to a first torque arm mounting bracket 26 fixed to the reclining frame 24 attached to the lower surface of the reclining portion 19.

  Similarly, as shown in FIGS. 4 and 7, the linkage 38 is rotatably connected to the second torque arm mounting bracket 28 fixed to the reclining frame 24.

  As shown in FIG. 4, the base portion 35 of the actuator 34 is rotatably connected to the actuator mounting bracket 24 a provided on the reclining frame 24, and the tip portion 36 a of the rod 36 is connected to the mounting bracket 33 p in the connecting member 33. To be pivotally connected. For example, the electric actuator 34 is connected to an elevating controller (not shown) for performing an input operation of the elevating position of the pocket portion 21, and the rod 36 is not extended or retracted according to the input operation of the elevating controller. It is configured to be adjustable in stages.

  That is, the elevating mechanism 30 according to the first embodiment includes first parallel links 31b and 32b having one end rotatably connected to the connecting member 33 and the other end rotatably connected to the mounting brackets (supports) 26 and 28, and A second parallel link 31a, 32a having one end fixed to the other end of one parallel link 31b, 32b and the other end rotatably coupled to the pocket portion 21 side; an actuator 34 for driving the connecting member 33; By moving the rod 36 of the actuator 34 to extend and contract, the pocket portion 21 is moved up and down through the first and second parallel links 31a, 32a, 31b, and 32b while maintaining the posture substantially horizontal. Configured to get.

  Here, as shown in FIG. 4, the interval between the first connecting portion 22j and the second connecting portion 22n in the pocket frame 22 is 22L, and the interval between the first connecting portion 33k and the second connecting portion 33m in the connecting member 33 is 33L. Assuming that the interval between the connecting portion 37r of the first torque arm mounting bracket 26 and the connecting rod 37 and the connecting portion 38r of the second torque arm mounting bracket 28 and the connecting rod 38 is L, “interval 22L = interval 33L”. Each interval is set so that the relationship of “= interval L” is established. That is, the intervals are set to be equal.

  Therefore, when the actuator 34 is operated to drive the rod 36 to extend, the pair of first and second torque arms 31 and 32 are connected to the torque arm mounting brackets 26 and 28 as shown in FIGS. By rotating counterclockwise while synchronizing the portions 37r and 38r as the center of rotation, the pocket portion 21 is raised in a state where the posture is maintained substantially horizontal.

  On the other hand, when the actuator 34 is operated to drive the rod 36 to contract, the pair of first and second torque arms 31 and 32 are connected to the torque arm mounting brackets 26 and 28 as shown in FIGS. By rotating clockwise while synchronizing the portions 37r and 38r as the rotation center, the pocket portion 21 is lowered while maintaining its posture substantially horizontal.

  As shown in FIG. 9, the support mechanism 40 that supports the backrest portion 23 at a required undulation position is adjustable and attached to a backrest frame 41 attached to the lower surface of the backrest portion 23. The stepless freelock device 45 having a built-in bracket 43 and a rod that can be locked at a required expansion / contraction position is constructed, and the base end side 45a of the stepless freelock device 45 is rotatable to the support 15. On the other hand, the free end side 45 b is rotatably connected to the mounting bracket 43. Thus, for example, the examiner sits in the vicinity of the stool indicated by reference numeral 17b in FIG. 1 and covers the patient for lying on the bed 13 with a posture that covers the patient for a relatively long time. When performing a screening while holding, the backrest part 23 in an upright state functions as a partition wall that separates the examiner and the patient, thereby preventing physical contact between the examiner and the patient. As a possible result, the mental burden on the examiner or patient can be greatly reduced, especially when the sex of the examiner and the patient is different.

  Here, for example, a medical examiner engaged in ultrasonic diagnostic work is in a state in which the ultrasonic probe is held in one hand and the patient's required location is searched for a relatively long time. It was a heavy physical burden. For example, in an echo probe for echocardiography, the position adjustment range related to the raising and lowering of the pocket portion 21 is made as large as possible and the position adjustment is performed because the dimension in the longitudinal direction varies depending on the device manufacturer. There was also a realistic request to make the stage as small as possible so that it can be fine-tuned. In addition, when the examiner is enthusiastic about the examination work at the actual examination site, the examiner and the patient tend to be in close physical contact, particularly when the examiner and the patient have different genders. There has also been a real problem that physical contact is a mental burden on the examiner or patient.

  On the other hand, according to the examination table 11 according to the first embodiment of the present invention, the examiner moves the pocket portion 21 steplessly while maintaining its posture substantially horizontal, and stops at the required lift position. Therefore, the examination can be performed in an easy posture with the arm, elbow, etc. of the examiner supported on the upper surface of the pocket portion 21.

  Further, for example, the examiner sits in the vicinity of the stool indicated by reference numeral 17b in FIG. 1 and grips the examination device for a relatively long period of time so that it covers the patient lying on the bed 13. However, when the medical examination is performed, the backrest part 23 in the standing state functions as a partition wall that separates the medical examiner and the patient, so that it is possible to suppress physical contact between the medical examiner and the patient. As a result, the mental burden on the examiner or patient can be greatly reduced, even when the sexes of the examiner and the patient are different.

  Therefore, according to the examination table 11 according to the first embodiment of the present invention, the physical or mental burden on the examiner or patient can be greatly reduced. As a result, the efficiency and accuracy of the examination can be improved. It becomes possible to plan.
