Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chair for otorhinolaryngology and other clinics, and more particularly to a chair for patients to sit in the otorhinolaryngology clinic, in which a doctor faces the patient for diagnosis and treatment, such as in an otorhinolaryngology clinic. This invention relates to a chair suitable for clinics where medical treatment is performed.

Various types of patient chairs have been proposed and used in the past, but in all of them, when the seat is raised or lowered according to the size of the patient, the head rest also moves up and down. . Each time, the headrest and seat had to be positioned so that the doctor's face was at eye level, and the hassle and effort involved was unimaginable.

Particularly in otorhinolaryngology clinics where doctors examine patients face-to-face, if they want to position the head rest according to the size of the patient, they must go behind the patient and move the head rest up and down, or You will have to go back to the front and check your position, and if it is still not in the correct position, you will have to repeat this process again. If the doctor does not do this, he or she will have to have a specialist stand by behind the chair where the patient is sitting. Therefore, it is desirable to develop a patient chair that does not require the doctor to stand up from the chair and adjust the position of the head rest, and that allows the doctor to easily adjust the position without the need for an extra person. I came.

The present invention has been developed in view of this point, and is designed so that the position of the head rest is set in advance at the eye level of the doctor using the device, and only the seat can be raised or lowered.

Prior to the completion of the present invention, the present inventor invented and tested a chair in which a bar was raised from the base and a head rest was attached to the top of the bar, but this did not work when the chair was laid down. It was discovered that the head rest had some drawbacks, such as misalignment and difficulty in transporting it because it was difficult to remove, and as a result of further research to improve these problems, the present invention was completed. The feature is that the head holder is attached to the upper end of the head holder, which is held on the base so that it does not shift vertically, via a support rod so that it can move up and down over a large angle. The head rest can be set at the eye level of the doctor using the head rest, and a seat part that can be moved up and down using a hydraulic cylinder or the like is installed on the base, separate from the head rest. A chair for a clinic is characterized in that by moving the seat part in the vertical direction, the distance between the seat part and the head rest can be adjusted to match the sitting height of the patient.

The present invention will be described in more detail below with reference to the illustrated embodiments.

In the figure, reference numeral 1 denotes a base having a built-in hydraulic cylinder 2 for raising and lowering, and a seat part 3 to be raised and lowered is attached to the upper part of the base 1 via the hydraulic cylinder 2. Therefore, the cylinder 2 allows the seat portion 3 to move up and down.

Reference numeral 4 denotes a leaf spring member, which connects the horizontal part to the base 1.
The lower end of the L-shaped member 5 is fixed to the base 1 by fixing it to the upright piece 5' of the L-shaped member 5 fixed to the base 1, and the upper part of the L-shaped member 5 is fixed to the base 1 by passing through the groove of the guide member 6 having a concave cross section. The guide members 6, 6' extend upward, and their upper ends are fixed to the head receiving part 7. The upright piece 5' of the L-shaped member 5 slides as the chair ascends and descends between the square-shaped notches 8 which are sandwiched and fixed and cut upward from the lower end of the hanging piece 6'. Therefore, when the seat part 3 is raised by the rise of the cylinder 2, the guide members 6, 6' move up together with the seat part 3 while deforming the leaf spring member 4.

Further, a head holder 9 is attached to the upper end of the head holder 7 through a support rod 8 so as to be able to move up and down over a large angle, so that the head holder 9 can be used in advance by a doctor before a medical examination. It is designed so that it can be set at eye level. Further, the head receiving portion 7 has the leaf spring member 4 fixed to its lower end, and is held by the base 1 so as not to shift in the vertical direction.

At the rear of the seat part 3, a chair main body 3' stands upward from the edge thereof, and a groove 3' having a concave cross section provided on the back of the chair main body 3' includes a groove 3'.
The inner end of the head receiving portion 7 is irremovably fitted. Therefore, when the seat portion 3 is raised, this chair main body 3' is also raised. At this time, since the inner end of the head receiving attachment part 7 whose lower end is fixed to the base 1 is fitted into the concave groove 3'' of the chair main body 3', the chair main body 3' does not rise while sliding. However, the head receiving portion 7 can maintain its fixed position.

To explain how to use the chair of the present invention having such a configuration, first, when the chair of the present invention is delivered to a clinic, the head rest 9 is placed so that the patient's face is at the eye level of the doctor using the chair. Adjust by tilting your head up and down, then fix the position. Therefore, once the position of the head rest is fixed at the time of delivery from the manufacturer to the clinic, there is no need to change the position at all unless the chair is used by another doctor.

By thus placing the patient on the seat 3 and turning on the foot switch and other electrical switches,
For example, if the patient is a child, the seat section 3 is raised and the distance between the seat section 3 and the head rest 9 is l.
If the height is narrowed and the lift is stopped when the patient's head reaches the position of the head rest, treatment and diagnosis can be performed as is. As the chair rises, the guide member 6 also rises while deforming the leaf spring member 4, so that the chair can be raised very easily and accurately.

As mentioned above, according to the chair of the present invention, the patient can always be brought to the treatment position by simply moving the chair up and down, regardless of whether the patient is an adult or a child, and the doctor can go around behind the patient and adjust the position. This has the advantage that positioning can be carried out without the need for any extra person to perform the adjustment.
