Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a pulse sensor device used in a portable electronic pulse meter.

(B) Prior Art As this type of pulse sensor device, a device in which a clip-like device is attached to a pulse detection site such as the user's earlobe is known. This device has a sensor case arranged like a clip, with a light emitter (lamp or LED element) built into one side and a light receiver (CDS element or phototransistor) built into the other, and spring biased to hold the earlobe. be.

(C) Purpose of the invention This invention allows the sensor cord that connects the light emitter and receiver of such a pulse sensor device and the pulse meter to be easily held in the sensor case without using any new parts. It is something.

(d) Structure of the invention The pulse sensor device of the invention has a pair of sensor cases that have a light emitter and a photoreceptor and are opposed to each other in a clip-like manner, and a cord storage recessed in the opposing surface of one of the sensor cases. A recessed groove, a sensor cord connecting the light emitting body and the photoreceptor to the pulse meter, and the pair of sensor cases are clamped and attached to the pulse detection site of the user, and one end of the sensor cord is fitted into the cord storage recessed groove. a spring that comes into contact with the cord and presses the cord in the direction of the groove;
The sensor cord is configured to be held by pressing the sensor cord against the sensor case with one end of a clamping spring of the clip-shaped sensor case.

(E) Embodiment 1 is a clothespin-shaped pulse sensor device that detects the user's pulse and obtains pulse pulses by being attached to the user's earlobe 2, which is a fixed part on the pulse side. By inputting the pulse pulses into the electronic pulse meter 3, the electronic circuit within the pulse meter 3 counts and processes the pulse pulses, and displays the pulse rate on the display section 3a.

In the pulse sensor device 1, reference numerals 5A and 5B are a pair of sensor cases, and these sensor cases 5A and 5B are opposed to each other in a clip-like manner so that their respective action parts 6a and 6b face each other, and each support piece 7 is attached to the sensor case 5A and 5B.
a and 7b are pivotally supported by a pivot shaft 8. 9a, 9b
A pair of storage recesses are formed in the action parts 6a and 6b so as to face each other, and one storage recess 9a is equipped with a light emitter 10 such as a tungsten lamp that emits a constant light, and the other storage recess 9b is equipped with a light emitting body 10 such as a tungsten lamp. is this luminous body 10
A light receiving body 11 such as a CDS light receiving element that receives light from the earlobe 2 by passing through the earlobe 2 is housed in each case. 12
a is a first transparent plate made of vinyl chloride that covers the opening of the storage recess 9a of the light emitter 10, and 12b is a second transparent plate made of vinyl chloride that covers the opening of the storage recess 9b of the light receiver 11. The second transparent plate 12b is a plate.
A light-shielding film 14 is provided by silk-screening the remaining parts in black, leaving small holes 13 for light passage. 1 more
Reference numerals 5 and 15 denote light-shielding covers that removably cover the action parts 6a and 6b from the outside of the first and second transparent plates 12a and 12b, and are made of elastic synthetic resin or synthetic rubber, and have a light-shielding cover in the center. Passage window hole 1
6, 16 and the working portions 6a, 6b.
Attachment periphery 17 for fitting and attaching around the
The earlobe 2 of the user is tightly attached to the earlobe 2 due to the elasticity of these covers 15, and stains due to sweat etc. during use are removed by these covers 1.
5, 15 can be removed by replacement or cleaning, and accurate pulse pulses can be obtained at all times.

Reference numeral 18 indicates a cord storage recess provided in the surface of one sensor case 5A housing the light emitting body 10 facing the other sensor 5B extending from the action portion 6a to the rear portion of the sensor case 5A; A sensor cord 20 connects between the light emitter 10 and the light receiver 11 and the pulse meter 3, supplies power to the light emitter 10, and transmits pulse pulses from the light receptor 10 to the pulse meter 3; A pair of action parts 16
It is a coil spring that biases a and 16b so that they approach each other, and is clipped and attached to the user's earlobe 2. and the sensor code 1
The coil spring 20 is wound around the support shaft 8 and has one end bent into an L shape. The cord pressing portion 21 is brought into contact with the sensor cord 19 in the cord storage groove 18 to press the cord 19 in the direction of the groove 18, thereby pushing the cord 19 into the groove. It is held in the groove 18. Note that 21 indicates a cord pressing portion of another embodiment.

(f) Effects of the invention As described above, the pulse sensor device of the present invention has a cord storage recessed groove in the sensor case, the sensor cord is inserted into the sensor case, and the pair of sensor cases is attached to the user's pulse detection site by sandwiching the sensor case. Since the spring is also used to hold the sensor cord in the groove, the sensor can be easily attached to the sensor case without the need for new parts for holding the sensor cord and without the need for caulking work. It can hold the cord and simplify assembly work. Furthermore, since the sensor cord is held elastically by a spring, the cord is less likely to break, making it possible to obtain a highly reliable pulse sensor device.
