Description

A kind of pulse frequency watch

Technical field

This utility model relates to medical instruments field, particularly a kind of can be in the device of long-time portable non-invasive pulse frequency and temperature check.

Background technology

Pulse frequency is meant that the per minute heart is effectively beaten and produces the number of times of pulse, and body temperature is meant the temperature of inside of human body, and pulse frequency and body temperature are the important parameters of assessing health, need continue to monitor.

The device of measuring pulse frequency at present adopts electronics, machinery and optical sensing usually; Electronic measuring device is to obtain pulse frequency through measuring body electrical signals, though this measuring method is simple, need the complex calculations rule with or contrast signal reduce the noise of motion generation; Mechanical type pulse frequency test set is usually in skin surface test pulse frequency; This instrument is quite simple, but this mode is easy to receive the interference of external motion, and optics pulse frequency test set is to utilize special light source and detector; Though precision is higher, instrument is more expensive and cause more energy expenditure easily.These three kinds of pulse frequency test sets all obtain to use widely according to the difference of test environment and test patient's characteristics.

The mode that take temperature is commonly used usually at present is special mercurial thermometer, thermocouple, thermistor thermometer and thermograph etc.; Modal clinical thermometer is a mercury clinical thermometer; It can make the mercury column with fervescence keep original position, and person easy to use observes at any time.Because the structure of glass is dense, the performance of hydrargyrum is highly stable, thus the glass clinical thermometer have indicating value accurately, characteristics that stability is high, cheap in addition, without the advantage of external power supply, receive particularly medical personnel's trust of people deeply.But the defective of glass clinical thermometer is also apparent in view, is prone to fragmentation, has the possibility of mercury pollution; Measuring Time is long, and anxious severe case, old man, infant etc. are used inconvenience, and read-around ratio is bothersome etc.Therefore; Along with science and technology development, the new-type clinical thermometer of a lot of types has appearred at present, and the critesistor clinical thermometer is exactly wherein a kind of; Critesistor clinical thermometer formula is utilized the definite relation that exists between resistance parameter and the ambient temperature of critesistor; The form of body temperature with numeral shown, clear reading, easy to carry.Its weak point is that the indicating value accuracy receives factor affecting such as electronic component and battery powered situation, not as the glass clinical thermometer.

On the whole, pulse frequency and temperature check device more and more develop to portable, digitized direction along with the development of biological electronics, greatly facilitate the be correlated with detection of health parameters of people.But; Pulse frequency detects and need dispose different specialized equipment with temperature check at present; Because this instrument can only detect single health indicator; Reduced the efficient that the medical worker detects, also increased patient's burden, carried pertinent instruments when also inconvenient patient goes on a journey simultaneously and detect health indicators such as pulse frequency and body temperature.

The utility model content

This utility model provides a kind of a kind of pulse frequency watch multiple functional, easy to carry and simple to operate for the technical problem that solves above-mentioned prior art existence.

The technical scheme of this utility model is following: a kind of pulse frequency watch of being made up of silica gel, critesistor, piezoelectric ceramics, last shell, lower casing, main frame; It is characterized in that: described critesistor and piezoelectric ceramics are bonded on the shell with seccotine; The pin of critesistor is introduced through two holes on the last shell and is gone up enclosure and link to each other with main frame, and piezoelectric ceramics introduces upward through two holding wires of welding that enclosure links to each other with main frame;

Further, described silica gel is installed in the top of critesistor and piezoelectric ceramics;

Further, there is boss at described two ends of going up shell, and the boss front end is for semicircle and have aperture, is the incoming line that comes off and indicate, and the boss rear end is circular;

Further, there is boss equally in the two ends of described lower casing, and corresponding with the semicircle boss of last shell, and display lamp and magnetic induction switch are installed on the lower casing bottom surface;

Further, described junction of going up shell and lower casing installation scribbles silica gel material, and fixes through screw at four jiaos.

The beneficial effect of this utility model is:

(1) owing in this pulse frequency watch critesistor and piezoelectric ceramics are installed simultaneously; When the old friend wears the pulse frequency watch; The temperature signal of human body converts electrical signal transfer to through the change in resistance in the critesistor and to main frame, handles; The pressure signal of pulse is delivered to the back of the hand place through the effect of power, and the back of the hand directly contacts silica gel power is delivered on the piezoelectric ceramics, and piezoelectric ceramics converts force signal to electrical signal transfer and to main frame, handles; Thereby can realize measuring body temperature and pulse frequency simultaneously, have multiple functional characteristics; The back of the hand directly contacted with silica gel when the people wore the pulse frequency watch simultaneously, can improve wearer's comfort level greatly;

(2) because all structure junctions of this pulse frequency watch all adopt water-proof silica-gel to seal,, adopt magnetic induction switch to start shooting simultaneously, have convenience operation so water-proof function is arranged;

(3) because this pulse frequency watch is designed with the indication incoming line that comes off, when finding that the wearer takes off watch privately, the watchband loop can be broken off, and it is little that can point out observer's watch to be got privately this moment, possesses prompting function.

Description of drawings

Fig. 1,2,3 is the structural representation of this utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment this utility model is described further:

Like Fig. 1; Shown in 2,3, a kind of pulse frequency watch; Partly form by silica gel 1, critesistor 2, piezoelectric ceramics 3, last shell 4, lower casing 5, main frame 9 etc.; Critesistor 2 is bonded on the shell 4 with piezoelectric ceramics 3 usefulness seccotines, and the pin of critesistor 2 is gone up shell 5 inside through two holes introducings on the last shell 5 and linked to each other with the main frame 9 of inside, and piezoelectric ceramics 3 is gone up shell 5 inside through two holding wires introducings of welding and linked to each other with inner main frames 9; Silica gel 1 is installed in the top of critesistor 2 and piezoelectric ceramics 3, is used for watch wearer the back of the hand and links to each other with silica gel 1, improves the comfort level of wearing.

There is boss at the two ends of the last shell 4 of described pulse frequency watch; The boss front end is for semicircle and have aperture, is the incoming line 8 of indication of coming off, and is used for being connected of main frame and the external index signal that comes off; The rear end is circular, is used for fixing with being connected of external device such as watchband etc.; There is boss equally in the two ends of lower casing 5, and corresponding with the semicircle boss of last shell, and display lamp 7 and magnetic induction switch 8 are installed on the lower casing bottom surface; Last shell 4 scribbles silica gel material with the junction that lower casing 5 is installed, and fixes through screw at four jiaos.
