Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chest examination chair, and more particularly to a chest examination chair used for medical examination of breast cancer.

Regular medical examinations are important for early detection of breast cancer. Breast cancer screening methods include visual examination, ultrasound examination, mammography examination, and CT/MRI examination. Among these health checkup methods, ultrasonic screening has so far been performed by placing a subject on his/her back in an examination bed and having a female doctor or laboratory technician apply an ultrasonic probe to the subject's breast. .. After the examination, the examinee is seated at the bedside, and a doctor or a laboratory technician interviews the examinee.

Here, the ultrasonic examination is performed for each breast on one side. At that time, the subject must take a posture in which one breast of the examination target is projected. For this reason, doctors and laboratory technicians place a cushioning material such as a pillow at a position that hits one breast between the back of the subject who lay on his back before the examination and the diagnostic bed, and the examination of one breast is completed. After that, the cushioning material must be moved to a position where it hits the other breast between the subject's back and the diagnostic bed. Furthermore, the subject, while supported by the cushioning material, needs to maintain a posture in which the chest of the subject to be examined is projected during the examination.

Doctors and laboratory technicians may screen a large number of subjects, and for female doctors and laboratory technicians, lifting the subject's body and placing a pillow between the subject's back and the diagnostic bed. Takes time. Further, it is very burdensome for the subject to maintain the posture in which one chest is projected.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a chest examination chair that places less burden on a doctor and a subject when performing an ultrasound examination of breast cancer.

The chest examination chair of the present invention includes a seat portion and a backrest portion that is reclining with respect to the seat portion, and the backrest portion is at a position corresponding to the chest of the subject who is seated on the chest examination chair, from the surface. It has a pushing mechanism that can advance to the subject.

According to the present invention having the above-described configuration, when the breast cancer screening is performed, the subject has the breast protruding by causing the push-out mechanism to protrude. Therefore, even a female doctor or laboratory technician can easily make the subject take a posture suitable for breast cancer screening. Also, since the back of the subject is supported by the pushing mechanism, the posture in which the breast protrudes can be maintained without burden.

In the present invention, preferably, the push-out mechanism is provided at each of the positions corresponding to the left and right breasts of the subject.
Breast cancer screening is performed for each of the left and right breasts one by one, but according to the present invention having the above-described configuration, by allowing only the pushing-out mechanism on the breast side of the test object to project, the posture of the test subject with only the breast area on the test object side extended. Therefore, it is possible to perform ultrasonic examination with higher accuracy. Further, unlike the conventional case, it is not necessary to change the arrangement of the cushion material for supporting the chest from below one chest to below the other chest.

In the present invention, preferably, projecting portions projecting toward the subject side are formed on both upper sides of the backrest portion.
When performing a breast cancer examination, it is desirable from the viewpoint of examination accuracy that the subject's breast be protruded and that the examinee take a posture in which the breast side arm of the subject is raised. According to the present invention having the above-described configuration, the subject can place the arm on the inspection target side on the protruding portion, and the burden on maintaining the posture with the arm raised can be reduced.

In the present invention, preferably, the backrest has a backrest main body that supports the back of the subject, and a head support that supports the head of the subject, and the chest examination chair has a backrest. It further comprises a position adjusting mechanism for adjusting the position of the head supporting part with respect to the part main body.

According to the present invention having the above-described configuration, by appropriately adjusting the position of the head support portion with respect to the backrest body by the position adjustment mechanism, even if the backrest portion is reclined at the time of breast cancer screening, the head support portion does not cover the backrest portion. Since the examiner's head is properly supported, it is possible to reduce the burden on the subject for breast cancer screening. Further, by bringing the head support portion close to the backrest body by the position adjusting mechanism, the throat of the subject is extended and the thyroid gland can be examined.

According to this embodiment, the following effects are exhibited.
According to the above-described embodiment, when the breast cancer screening is performed, the push-out mechanism 16 is caused to protrude, so that the subject P has the breast protruding. For this reason, even a female doctor or an inspection technician can easily make the subject P take a position suitable for breast cancer screening. Further, during the examination, since the back of the subject P is also supported by the pushing mechanism 16, the posture in which the breast protrudes can be maintained without burden.

In addition, in the above-described embodiment, the push-out mechanism 16 is provided at each of the positions corresponding to the left and right breasts of the subject. In the breast cancer screening, the left and right breasts are performed one by one, but according to the above-described embodiment, by allowing only the pushing-out mechanism 16 on the breast side of the examination target to project, the posture of the subject P in which only the chest on the examination subject side is extended. Therefore, it is possible to perform ultrasonic examination with higher accuracy. Further, unlike the conventional case, it is not necessary to change the arrangement of the cushion material for supporting the chest from below one chest to below the other chest.

Further, in the present embodiment, arm support portions 64 that project toward the subject P side are formed on both upper sides of the backrest portion 6. When carrying out a breast cancer examination, it is desired from the viewpoint of examination accuracy that the examinee P sticks out the breast to be examined, and the posture of the subject P including the arm on the breast side of the examination is taken up. On the other hand, according to the present embodiment, the subject P can place the arm to be inspected on the arm support portion 64, and the burden of maintaining the posture of raising the arm can be reduced.

Further, in the present embodiment, the backrest portion 6 has a backrest portion body 12 that supports the back surface of the subject P and a head support portion 14 that supports the head of the subject P, and a chest examination is performed.
