This system includes: by two function regions of hinge connection, and two regions open and shut the angle for being not less than 200 degrees, hand and foot's electrode all have the power, can produce the multi -frequency signal of telecommunication to having essential analog -to -digital conversion and wireless transmitting, receiving the function, start shooting when handheld electrode takes out, the system shuts down when putting into, and the thumb position begins when pressing to measure. Electrode sensing device includes 8 contact electrode, and pulse current emergence portion can produce the pulse current of 5 different frequencies, this pulse current takes place in proper order to the electrical impedance value of the different health compositions in the same position of accurate measurement, the utility model discloses it is small, probably 40cm30cm5cm after folding, portable is fit for more occasions and time quantum use, can become the conventional detecting instrument of family.

Description

Wireless two width open-close type bioelectrical impedance analysis instrument

Technical field

This utility model relates to electric class, particularly relate to one and utilize the multi-frequency signal of telecommunication, sections measuring technique, based on two width open-close type bioelectrical impedance analysis instruments of wireless data sending, described instrument uses the impulse current measurement human body impedance value of multiple height different frequency, and described sections measuring technique is measurement impedance area being divided into left and right upper limb, trunk and left and right lower limb.

Background technology

The health of people is made up of water, protein, fat, inanimate matter four kinds of compositions, and its normal rates is: water accounts for 55%, and protein accounts for 20%, and fat accounts for 20%, and inorganic matter accounts for 5%.The equilibrium of human body component is the most basic condition maintaining health status.

When body fat ratio is lower than standard ratio, having two kinds of situations: a class is the muscularity physique that quantity of motion is many, is desirable physique, and another kind of is malnutrition, is unhealthy condition.Usually, 50% of body fat is distributed in extremity, and stomach fat ratio is waist buttocks week footpath rate (i.e. WHR) measured by WHR method.Man's normal value is 0.75 ~ 0.85, and woman's normal value is 0.70 ~ 0.80.Inanimate matter is the pillar maintaining health framework, to be polymerized to form firm skeleton containing protein with calcareous inanimate matter.If come off from skeletal tissue calcareous and to excrete with urine, the density of skeleton reduces gradually, and originally calcareous shared space empty has been fallen, and will cause osteoporosis.

The health of the mankind can be considered and be made up of five parts: upper limb, lower limb and trunk.Trunk is the part that the electrical impedance index of human body is minimum, at about 20 Ω, as for upper limb part, common electrical impedance is at 300 Ω, so trunk occurs the change of very little 2-3 Ω, the resistance change of 20 ~ 30 very large Ω then can be caused in upper limb part, mutually commensurability moisture or muscle, if position, place is different, then on impedance to affect intensity also not quite identical.Therefore, in order to ensure the measurement accuracy of torso portion electrical impedance, it is necessary for developing accurate measuring technique.

But existing measuring body composition assessment apparatus, volume weight is general larger, move and be all not easy, inconvenience uses in more occasion, and therefore, design improves measuring body composition assessment apparatus, maintenance existing even improve the prerequisite of certainty of measurement under, make it miniaturization, portability, just seem particularly important.

Utility model content

This utility model is that one utilizes the multi-frequency signal of telecommunication, sections measuring technique, based on two width open-close type bioelectrical impedance analysis instruments of wireless data sending.This system comprises: by two width functional areas of gemel connection, and the folding angle in two width regions is for being not less than 200 degree.Hand and foot's electrode all have power supply, can produce the multi-frequency signal of telecommunication, and have basic analog digital conversion and wireless transmit, receiving function.Hand-held electrode is placed on card and puts in groove, by referring to that nest position plucks out, systematic press release type switch in draw-in groove, system boot when hand-held electrode takes out, system closedown when putting into.Respectively there is a push switch thumb position, and when left hand position is pressed, ordinal number increases 1, starts to measure when right hand position is pressed.Electrode sensing device, this device comprises 8 contact electrodes; Pulse current generating unit, can produce the pulse current of 5 different frequencies, and this pulse current described occurs in sequence, so that the impedance value of the different body composition in the same position of Measurement accuracy.

The beneficial effects of the utility model are: this utility model volume is little, be approximately 40cm*30cm*5cm, be easy to carry after folding, are applicable to more occasion and time period use, can become the conventional sense instrument of family.

Detailed description of the invention

Further illustrate feature of the present utility model below: easy and simple to handle, experimenter only need open wireless two width open-close type bioelectrical impedance analysis instrument, lie on the ground, refer to that nest position plucks out hand-held electrode from hand-held electrode, namely equipment enter holding state, stand on foot electrode, hold hand-held electrode, thumb presses assigned address, namely start to measure, about 30 second time can complete whole measurement, and drew body moisture, protein, muscle, fatty measured value and the many index such as stomach fat ratio, body constitution percent immediately.Operating procedure is: 1, host computer is standby, at the standby rear search equipment serial number of checkout equipment, completes authentication.2, on host computer, input the personal information such as numbering, name, sex, age, height, body weight of experimenter.3, experimenter takes off socks, with electrolysis wet paper towel wiping trick, stands on foot electrode, and grasping handle electrode naturally hangs down and to separate with health and to press thumb position.4, when not connecting host computer, can continuous measurement 30 example, and name test data in the mode that the time adds sequence number.5, after connecting host computer, personal information can be supplemented to complete analysis.
