Abstract

PURPOSE:To provide a toilet seat apparatus having an electrocardiographic function by which electrocardiographic waveforms can be measured in various induction ways and electrocardiographic waveform measurement can be carried out excellently without applying a conductive cream to hands. CONSTITUTION:The toilet seat apparatus is provided with a toilet seat 14, electrocardiographic electrodes 22, 24 for the lower limbs implanted in the sitting face of the seat, and electrocardiographic electrodes 32, 34 for the upper limbs put on the sides of the toilet seat 14. Since the electrocardiographic electrodes 32, 34 for the upper limbs are so made as to be held by hands, a user can keep the contact pressure between the electrodes 32, 34 and the palms relatively high and uniform. As a result, without using a conductive cream, the contact resistance between the palms and the electrodes can be suppressed to be low.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat device having an electrocardiographic measurement function. In particular, the present invention relates to a toilet seat device having an electrocardiographic measurement function capable of excellent electrocardiographic waveform measurement without applying a conductive cream to the hands.

[0002]

2. Description of the Related Art A toilet seat device having a plurality of electrocardiographic measurement electrodes attached to a toilet seat or the like and a signal processing unit for processing an electric potential signal detected by these electrodes and displaying an electrocardiographic waveform is known. is there. In the toilet seat device disclosed in Japanese Utility Model Laid-Open No. 61-18105, a pair of left and right electrocardiographic measurement electrodes attached to the toilet seat cover come into contact with the lower limbs (left and right thighs) of the human body to detect a potential difference between the electrodes. By doing so, the electrocardiographic waveform and heart rate are detected.

[0003]

DISCLOSURE OF THE INVENTION In this device,
It is possible to obtain some electrocardiographic waveform by the electrode attached to the toilet seat cover, but it is not possible to obtain the electrocardiographic waveform by the standard limb lead method or single-limb lead method that is medically significant. Met. In order to measure an electrocardiographic waveform by the standard limb lead method, an electrode that contacts the user's upper limb is required. It is relatively easy to provide an electrode for the upper limb following the above-mentioned No. 61-18105, but for the lower limb that is strongly contacted with the electrode by its own weight, the upper limb is to the electrode. It is difficult to make strong contact with the electrode, and pressing the palm of the hand against the electrode with a constant force in order to suppress the fluctuation of the polarization potential is also a pain for the user.

In order to keep the contact resistance low under a comparatively weak contact pressure, there is a method of applying a conductive cream to the palm to improve the conductivity between the hand and the electrode. But,
When a conductive cream is used, it takes a lot of time to apply and wipe the cream, and there is a problem that the cream adheres to the operation switch of the toilet seat device having an electrocardiographic measurement function and becomes dirty. After all, a device in which the user is forced to use the conductive cream becomes a device with poor usability.

The present invention provides a toilet seat device having an electrocardiographic measurement function capable of measuring electrocardiographic waveforms by various induction methods and capable of excellent electrocardiographic waveform measurement without applying a conductive cream to the hands. The purpose is to provide.

[0006]

In order to solve the above problems, a toilet seat device having an electrocardiographic measurement function of the present invention is a toilet seat, an electrocardiographic measurement electrode for lower limbs attached to a seating surface of the toilet seat, and a toilet seat And a laterally arranged upper limb electrocardiographic measurement electrode; the upper limb electrocardiographic measurement electrode is formed so as to be gripped by a hand.

[0007]

Since the upper limb electrocardiographic measurement electrode is gripped with the hand, the user can keep the contact pressure between the upper limb electrocardiographic measurement electrode and the palm relatively high and uniform. Therefore, the contact resistance between the palm and the electrode can be suppressed low without using a conductive cream.

(Rotating type), the housing 18 of the toilet seat device, and the toilet lid 16 are installed.

To the left and right of the upper surface (seating surface) of the toilet seat 14,
Electrocardiographic measurement electrode for lower limbs (right side from seated user) 2

The electrodes 22 and 24 have a conductive upper surface (metal plate, metal foil, etc.), and the wirings (shield lines) 26 and 28 are connected to them. The lower limb electrocardiographic measurement electrodes 22, 24 capture the potential signals of the left and right thighs of the person (user) sitting on the toilet seat. The electrocardiographic signals captured by the electrodes 22 and 24 are the wirings 26 and 28.

On the other hand, grip bar-shaped upper limb electrocardiographic measurement electrodes 32 and 34 are provided on both sides of the toilet seat 14. Specifically, the shafts 33 and 35 are formed integrally with the toilet seat 14 and project outward from the side surface of the toilet seat 14. At the tips of the shafts 33 and 35, upper limb electrocardiographic measurement electrodes 32 and 34 made of a conductive material (for example, stainless steel) are provided.

The electrocardiographic measurement electrode 32 'for the upper limb has a cross section shaped like a curved arc with one side concave and one side convex. A rod having a cross section as shown in FIG. 2 is easier to grip than a rod having a completely circular cross section. It should be noted that the electrocardiographic measurement electrode for the upper limb is provided so as to extend in the upward direction, or the housing 18 (FIG. 1) is extended to the side of the toilet body 12 so that the housing 1
It is also possible to attach a rod-shaped upper limb electrocardiographic measurement electrode to 8.

The signals from the upper limb electrocardiographic measurement electrodes 32 and 34 are comprehensively contrasted with the electrocardiographic signals from the lower limb electrocardiographic measurement electrodes 22 and 24 to finally obtain an electrocardiographic waveform by a standard limb induction method or the like. To be

The electrocardiographic signal captured by 34 is sent to the signal processing unit 30 through a wiring (not shown). The electrocardiographic signal is first amplified by the electrocardiographic amplification circuit 38 in the signal processing unit 30, and then A /
A / D conversion is performed by the D conversion circuit. The digitized electrocardiographic signal is subjected to subtraction calculation in the signal processing circuit 42 to become electrocardiographic waveform data.

The electrocardiographic waveform data is sent to the printing section 50 and the liquid crystal display section 46 in the operation display section 36. Printing unit 50
Prints the electrocardiographic waveform data on a recording paper as an electrocardiographic waveform and outputs it. The liquid crystal display unit 46 scroll-displays the electrocardiographic waveform. It should be noted that the user can select the print display or the liquid crystal display. The power switch 44 of the operation display unit 36 is a switch for turning on / off the power of the electrocardiographic measurement function.
The panel switch 48 is a switch for performing the above-described output selection, selection of the electrocardiographic waveform induction method, and the like. The operation display unit 36 can be installed on the upper surface of the housing 18 or the like as shown in FIG.
