Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a medical step table, more specifically to electrocardiograms, by having a subject perform ascending and descending movements and applying a constant load. This invention relates to a medical step table for taking an electrocardiogram under exercise stress.

[Conventional technology]

Conventionally, the most common method for electrocardiograms is to take an electrocardiogram with the subject lying on a bed in a resting, unloaded state. There may be cases where it is desired to take an electrocardiogram while the patient is in a state of stress to examine the functional state of the heart in more detail.

One way to apply this load is, for example, to exercise by going up and down stairs, but in order to more accurately grasp and set the amount of load, as a conventional example, we use the universal standard dimensions shown in Figure 8. There is a method using a manufactured medical step stand.

This is used by placing a medical step stand with a substantially convex cross section with two steps on the floor 1, with a first step _h1 between the upper surface 2a and the floor 1. Near the center of the upper surface of the base 2 having the base 2, the upper surface 3a and the base upper surface 2 are narrower in front and back than the base 2.
A central stand 3 having a second step h ₂ is placed and fixed between the central stand 3b and the center stand 3b, and can be moved by hooking the hand into the latching hole 3e on the side surface 3b of the central stand. . The subject first moves from the floor 1 to the base front 2b side of the base 2, which constitutes the first step _h1 of the medical step table placed on the floor 1, to the base top surface 2a. Next, climb up to the center stand top surface 3a of the center stand 3 that constitutes the second step _h2 , and then descend from there on the center stand rear surface 3c side on the opposite side of the center stand 3 onto the base top surface 2a. Finally, by reciprocating a series of step movements of descending onto the floor surface 1 on the rear surface 2c of the base, by repeating this, the robot can be moved immediately after applying a certain exercise load that can be grasped, and for a certain period of time thereafter. Cardiac function is diagnosed in more detail by taking electrocardiograms as the condition progresses.

Furthermore, since adults and children have different body sizes, medical step tables are standardized in three sizes: one for elementary school students, one for junior high school students, and one for adults (including high school students).

[Problem that the invention attempts to solve]

However, in all of the conventional medical step stands, the central stand 3 is fixed on the base 2, so the generally convex cross-sectional shape unnecessarily occupies space even when not in use. There was a problem in that it was inconvenient to pack and transport the medical step table associated with mobile medical treatment.

In addition, medical step tables for adults, junior high school students, and elementary school students are not interchangeable, and it is economically expensive to prepare each of these three sizes, as well as requiring a large amount of transportation. There was a dot.

The present invention aims to solve the above problems.

[Means for solving problems]

In order to achieve the above object, the present invention provides the following medical step stand. That is, the present invention includes a box-shaped base with an open bottom surface that is placed on the floor and forms a first step between the top surface and the floor surface, and a box-shaped base that is placed on the base and has a first step between the top surface and the floor surface. and a central stand forming a second step between the top surface of the base and the top surface of the base, and a step switching section provided in the base for switching the height of the second step to a different constant height. and a fixing device for fixing the central platform, in which the second level difference is switched to a constant height at the level difference switching part, on the platform.

[Effect]

In the above configuration, the base is placed on the floor surface, so that the top surface of the base forms a surface having a different height from the floor surface, that is, a first step.

Further, the central stand forms a second step between the upper surface of the central stand and the upper surface of the base.

Further, the step switching section switches the value of the second step between the central stand and the base to a different constant value, and sets the second step to a predetermined height according to the physique of the subject. do.

Further, the fixture fixes the second step that has been switched and set by the step switching section.

The center base can be stored in a box with an open bottom surface.
