ABSTRACT:
BACKGROUND OF INVENTION
1. Field of Invention
This invention relates to a urinary incontinence treatment instrument for applying a magnetic line of force to a treated patient for urinary incontinence treatment.
2. Related Art
A urinary incontinence treatment apparatus with a magnetic stimulating coil buried in a chair is shown, for example, in JP-A-9-276418. According to such an apparatus, urinary incontinence treatment is conducted in the same state as a patient sits in a normal chair, so that easy treatment can be conducted without burdening the treated patient or the operator with the treatment.
In magnetic stimulating intended for urinary incontinence treatment, an eddy current is produced in a living body by a fluctuating magnetic field for stimulating the pelvic floor muscle or pudendal nerve from urethral opening to the anus or perineum neighborhood. At this time, to suppress power consumption, it is necessary to efficiently give an effective stimulus to the parts.
In the apparatus in the related art, if the treated patient sits in a treatment chair, generally a magnetic line of force is applied to the portion from the femoral region to the buttocks of the treated patient; the apparatus does not efficiently give an effective stimulus.
SUMMARY OF INVENTION
It is therefore an object of the invention to efficiently generate an eddy current at the part of a treated patient to be stimulated in urinary incontinence treatment.
According to a first aspect of the present invention, there is provided a urinary incontinence treatment instrument comprising a magnetic stimulating coil, a magnetic stimulating coil support section for supporting the magnetic stimulating coil, the magnetic stimulating coil support section comprising an abutment face for abutting the buttocks and the femoral region of a treated patient on the periphery of the magnetic stimulating coil, and sense means for causing a treated patient to sense that the treated patient abuts the abutment face in a predetermined state. According to the urinary incontinence treatment instrument, the treated patient can be made to sense whether or not the magnetic stimulating coil is placed at a proper position.
In the present invention, in the urinary incontinence treatment instrument, the sense means is a projection made on the top of the magnetic stimulating coil. Thus, the treated patient can sense whether or not the magnetic stimulating coil is placed at a proper position in response to the touch of the projection.
In the present invention, in the urinary incontinence treatment instrument, a notch for inserting a micturition checker is made at the front center of the abutment face of the magnetic stimulating coil support section. Thus, the checking person can insert a micturition checker through the notch.
In the present invention, in the urinary incontinence treatment instrument, the portion of the abutment face placed at the position of the crotch of the treated patient in a state in which the buttocks and the femoral region of the treated patient abut the abutment face is shaped like a protrusion. Thus, when the instrument is used, the treated patient is placed in a position sitting astride the instrument.
In the present invention, in the urinary incontinence treatment instrument, the sense means is an abutment face having a recess shaped so as to accept the buttocks and the femoral region of the treated patient. Thus, the treated patient can sense whether or not the magnetic stimulating coil is placed at a proper position in response to the abutment feel of the buttocks and the femoral region against the abutment face.
In the present invention, in the urinary incontinence treatment instrument, the recess is shaped like two grooves for accepting the buttocks and the femoral region of the treated patient so that the treated patient is placed in a position sitting astride the instrument. Thus, when the instrument is used, the treated patient is placed in a position sitting astride the instrument.
In the present invention the urinary incontinence treatment instrument further includes means being placed on the periphery of the magnetic stimulating coil or the outer surface thereof for cutting off or preventing a sound produced from the magnetic stimulating coil. Thus, the sound produced from the magnetic stimulating coil is cut off or prevented.
In the present invention, in the urinary incontinence treatment instrument, the magnetic stimulating coil is shaped like a saddle bent so as to fit to the abutment part of the treated patient. Thus, the magnetic stimulating coil fits to the abutment part of the treated patient and the magnetic stimulating coil and the treated patient can be brought into intimate contact with each other.
