Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a chest measuring instrument that measures the thickness of the torso such as the chest and abdomen of a subject during medical radiography, etc. The present invention relates to a chest measuring instrument that can easily measure a subject who is lying on top.

[Conventional technology]

When performing radiography of the chest, abdomen, etc., accurately measure the thickness of the subject's torso such as the chest and abdomen.
A radiation dose corresponding to the thickness must be applied. Therefore, a chest measuring instrument as shown in FIG. 4 is used.

This chest monitor 1 includes a straight scale 3 having a scale 2 on its surface, a fixed scale 4 having a base 4a fixed to the tip of the straight scale 3, and a base 5a movable on the straight scale 3. It is formed by a movable scale 5 provided. Both measurement parts 4b and 5b on the tip side of the fixed scale 4 and the movable scale 5
extend from both base portions 4a, 5a in a direction perpendicular to the straight length 3, and both measurement portions 4b, 5b.
the base 5a of the movable scale 5 while holding the torso of the subject.
The thickness of the torso is measured by reading the position on the scale 2 of the straight ruler 3.

[The problem that the idea attempts to solve]

However, in the case of patients who cannot stand up, such as emergency patients or seriously injured patients, measurements must be taken while the patient is lying down on the bed. Because the fixed scale sinks and curves due to the patient's own weight, it is difficult to insert the fixed scale between the patient and the futon, etc., and even if it is inserted, the elasticity of the futon etc. may make the measurement angle inappropriate and the body part It was difficult to measure the thickness accurately.

Therefore, an object of the present invention is to provide a chest measuring instrument that can easily and accurately measure the thickness of the torso even when the subject is in a supine position.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a fixed scale having a base fixed to the tip of the straight scale provided with a scale, and a movable scale having a base movably attached to the straight scale. In a chest measuring instrument that measures the thickness of the torso of a subject by holding the torso between the measuring parts on the tip sides of a fixed scale and a movable scale, the bases of the fixed scale and the movable scale are bent, each measuring part on the tip side is deviated in parallel to the tip direction of the straight length, or
The base of the fixed scale is bent, the measuring part on the distal end side thereof is deflected in parallel to the distal end direction of the straight scale, and the scale of the straight scale is adjusted according to the amount of deviation of the measuring part of the fixed scale. It is characterized in that it has been corrected and provided.

〔Example〕

Hereinafter, a first embodiment of the present invention will be described based on FIGS. 1 and 2.

The chest monitor 10 of the present invention includes a straight scale 12 having a scale 11 on its surface, and a fixed scale 1 having a base 13a fixed to the tip 12a of the straight scale 12, as in the conventional one.
3, and a movable scale 14 having a base 14a movably provided on the straight scale 12.

The fixed scale 13 and the movable scale 14 have base portions 13a and 14a bent toward the tip of the straight length 12, and measuring portions 13b and 14b on the tip side of the straight length 12.
It is formed so as to deviate parallel to the direction of the tip. The amount of deviation t is appropriately set depending on the hardness of the bedding on the bed, etc., but generally, 3 to 7 cm is appropriate, and a deviation of about 5 cm is sufficient. If the amount of deviation is small, it will not be able to sufficiently cope with the curvature of the futon, etc. On the other hand, if the amount of deviation is large, it will be difficult to manufacture and the material will be wasted.

Further, the amount of deviation t of the fixed scale 13 and the movable scale 14 is the same, and both measurement parts 13b and 14b are formed so as to be deflected and abutted while remaining in a parallel state. That is, when the base 14a of the movable scale 14 comes into contact with the base 13a of the fixed scale 13, both measuring parts 13b, 14b
are also formed so as to come into contact with each other. This results in
The scale 11 provided on the straight scale 12 has its starting point 11
It is possible to use a scale for a that starts from zero as in the conventional case, and a conventional straight scale can be used as is. Therefore, the fixed scale and movable scale of the conventional chest monitor are
Fixed scale 13 and movable scale 14 formed as described above
It can be easily formed by replacing it with .

Figure 2 shows the chest measuring instrument 10 formed as described above.
This indicates the usage status of the .

The futon 15 on the bed is the patient 16 who is the subject.
It sinks due to the weight of the patient 16 and curves as shown in the figure depending on the body shape and weight of the patient 16. In this state, when the measuring part 13b on the distal end side of the fixed length 13 is inserted between the patient 16 and the futon 15, the measuring part 13
b is deviated from the base 13a, the base 13a of the fixed length 13, that is, the tip 12 of the straight length 12
Since a can be positioned above the futon,
The resistance received from the futon 15 when inserting the measuring part 13b is almost eliminated, making it easier to insert the measuring part 13b. Also, the torso of the patient 16 and both measuring parts 13
Similar to the insertion of the measuring part 13b, positioning with the measuring part 13b and the measuring part 14b can be easily performed with almost no resistance from the futon 15, and the thickness of the torso of the patient 16 can be accurately measured. be able to.

FIG. 3 shows a second embodiment of the present invention.
Only the fixed length is bent.

This chest monitor 20 has a fixed scale 21 bent as in the first embodiment, a movable scale 22 in a straight line as in the conventional example, and a scale 24 provided on a straight scale 23. , the measuring part 21 of the fixed length 21
This is corrected according to the deviation amount s of a. That is, when the deviation amount s of the measuring part 21a is set to 5 cm, the state in which the base 21b of the fixed scale 21 and the base 22a of the movable scale 22 are in contact with each other is defined as both measuring parts 21a, 2.
The starting point 24 is the scale indicating 5 cm, which is the interval of 2b.
It is located in a. Thereby, the thickness of the torso of the patient 16 can be determined by reading the position of the base 22a of the movable scale 22 on the scale 24 in the same manner as in the conventional method.

This chest measuring instrument 20 is also the chest measuring instrument 10 of the first embodiment.
However, in this embodiment, the bending process of the movable scale 22 when manufacturing the chest monitor 20 can be omitted, so that the process cost can be reduced.

As explained above, the chest monitor of the present invention has the following features:
Although it is suitable for measuring the torso of a patient in a supine position, it can of course also be used to measure the torso of a patient in an upright position.

[Effect of idea]

As explained above, the present invention bends the base of the fixed scale of the chest measuring instrument, deflects the measuring part on the tip side parallel to the direction of the tip of the straight scale, and adjusts the movable scale according to the amount of deviation. By deviating the scale in the same way or by correcting the scale of the straight scale, the measurement part at the tip of the fixed scale can be deviated to facilitate insertion and positioning between the subject's body in the supine position and the futon, etc. The thickness of the torso of the subject can be easily and accurately measured.

Furthermore, since it can be similarly used to measure the torso of a subject in an upright position, accurate measurement values can be obtained for the subject in either the standing or lying position.
