1. Field of the Invention
The invention relates to a heart rate monitoring device and particularly to a model that is provided with a heart rate monitoring module and that may be clipped onto the clothes, of which electrode pads are used to monitor the heart rate and a radio frequency module is used to transmit a heart rate signal to a specified storage device to receive and display.
2. Description of the Related Art
Conventionally, people's heart rate remarkably varies before and after people take exercise. During exercise, measuring the variables is very important. To take exercise properly and advantageously, the heart rate must increase to 60% of the maximum rate; however, if the heart rate increases to the maximum rate during exercise, it will do harm to the exerciser. Thus, a user-friendly and precise heart rate measurement device is very important for taking exercise to keep fit.
Next,
1. Generally, the heart rate monitoring unit 60 is tight bound with the belt 61 on the chest to keep close to; however, the lung capacity increases during exercise and thus the belt bound up on the chest causes a user to be uncomfortable and breathe hard.
2. Female chest contour is bigger, so the heart rate monitoring unit 60 cannot stay fully close to the chest, thereby the accuracy of monitoring decreasing.
3. To accurately measure the heart rate, the heart rate monitoring unit 70 cannot be bound outside the clothes but inside the clothes and close to the chest, so the belt 71 is placed certainly after the clothes is taken off, which might be somewhat inconvenient to males but may be implemented none the less; however, it is very inconvenient to females to bind up the belt 71 in a public place; thus, the conventional belt is not properly used by the female.
Consequently, because of the technical defects of described above, the applicant keeps on carving unflaggingly through wholehearted experience and research to develop the present invention, which can effectively improve the defects described above.
For this reason, it is a main object of the invention to solve the defects of the existing products and to provide a clip-type monitoring device for wirelessly transmitting a heart rate whoses housing is light and thin and conveniently hanged on the clothes without burden. Meanwhile, the positive and negative pads of the heart rate monitoring unit are conveniently made to stay fully close to the left and right chests. Thus, it is convenient for the female users to take exercise. Besides, the monitoring accuracy can be increased.
It is a further object of the invention to provide a clip-type monitoring device for wirelessly transmitting a heart rate, of which positive and negative electrode pads passes through a human body to be conducted. In consideration of the factors of voltage that is generated when the blood circulates through the human body, that varies with variable heart rate, and that is more distinct regular if the blood in the human body is quite away from the elements, a more accurate heart rate may be obtained.
In order to achieve the above-mentioned objects, the clip-type monitoring device for wirelessly transmitting the heart rate includes:
a) a housing having a clip at the back thereof, the clip being clipped onto the clothes, a jack being formed at the flank thereof for receiving an external signal;
b) a heart rate monitoring unit having a plurality of electrode pads extending out of the housing and staying close to the human body's chest to monitor the pulsation, each of the electrode pads being connected with a conducting wire, a plug being provided at a influx terminal for electrically coupled to the jack such that a measured voltage variation rate is transmittable to the inside of the housing;
c) a voltage sensor unit disposed within the housing and provided with three inductors and a filtering shaping amplifier circuit so that the voltage variation frequency measured by the heart rate monitoring unit is filtered by the inductors and then transmitted to the filtering shaping amplifier circuit to receive an amplified signal;
d) a control interface provided on the surface of housing to control the heart rate monitoring unit and the voltage sensor unit to turn ON and OFF; and
e) a radio frequency module having a wireless signal transmission circuit and provided in the housing for transmitting the signal amplified by the voltage sensor unit to a display storage device provided with a wireless signal receiving circuit.
The accomplishment of this and other objects of the invention will become apparent from the following descriptions and its accompanying figures of which:
Now, the present invention will be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of the invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
First, with reference to
a housing 10 of which the back is formed with a clip 13, as shown in
a heart rate monitoring unit 20 being multiple electrode pads extending out of the housing 10, which stay close to the human body's chest to monitor the pulsation, in this embodiment, comprising a positive electrode pad 21, a negative electrode pad 22, and a common electrode pad 23; a lead wire 24 to which each of the electrode pad 21˜23 are provided along a wire influx terminal provided with a plug 25 that may be electrically connected to a jack 11, thereby a measured voltage variation rate being transmitted to the housing 10;
a voltage sensor unit 30, as shown in
a control interface 12 provided on the surface of housing 10 to control the heart rate monitoring unit 20 and the voltage sensor unit 30 to turn ON and OFF; and
a radio frequency module 40 through which a wireless signal transmission circuit 41 provided in the housing 10 transmits the signal amplified by the voltage sensor unit 30 to a display storage device 50 provided with a wireless signal receiving circuit 42.
In the invention, to monitor the heart rate, as shown in
For properly taking exercise, the invention is mainly featured with the light, thin housing body 10 of low volume and weight for easy clipping on the clothes without burden. For this purpose, in the invention, the heart rate monitoring unit 20 is provided with extremely light and thin electrode pads 21˜23 to measure the voltage variation rate of the chest, and the display unit occupying more space further displays it through a peripheral electronic product; namely, the radio frequency module 40 is designed in the invention to transmit a measured heart rate signal through a wireless signal transmission circuit 41 to a display storage device 50 provided with a wireless signal receiving circuit 42. Thanks to amazingly fast technology, most of the current electronic products are provided with a display panel, for example, as shown in
Further, as shown in
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
