Abstract

A device for monitoring vital signs in animals. A rectal thermometer is mounted on a probe and connected to a handle. A central processing unit in the handle displays the temperature recorded by the thermometer. Also connected to the handle is a cuff used for pulse monitoring. The handle has a timer to measure an elapsed time and to sound a tone in response to a determined amount of time passing. In some application the cuff may have a blood pressure monitor so the device can measure temperature, pulse, blood pressure, and to record and sound a tone noting the elapse of a predetermined time to aid in counting respirations.

Claims

1. An instrument for checking vital signs of an animal comprising:

(a) means for sensing a temperature mounted on a probe electrically coupled to a central processing unit to record and display a temperature sensed by said means for sensing a temperature;

(b) means for sensing a pulse electrically coupled to said central processing unit, said central processing unit to record and display a pulse sensed by said means for sensing a pulse;

(c) a timer connected to said central processing unit whereby said central processing unit can calculate and display an elapsed time;

(d) a means for sounding an audio signal when an elapsed time has been calculated by said central processing unit;

(e) means for providing electrical power to said central processing unit, said means for sensing temperature, said means for sensing a pulse, and said timer;

(f) means for controlling the operation of said central processing unit, said timing means, and said electrical power means.

2. An instrument for checking vital signs of an animal of claim 1 wherein said probe is sized and shaped to be inserted into a body cavity of an animal.

3. An instrument for checking vital signs of an animal of claim 2 wherein said probe is sized for insertion into the rectal cavity of an animal.

4. An instrument for checking vital signs of an animal of claim 1 wherein said central processing unit is housed in a handle electrically coupled to said probe and said central processing unit further comprises a means for displaying temperature, a pulse rate, and an elapsed time.

5. An instrument for checking vital signs of an animal of claim 4 wherein said instrument further comprises means for determining blood pressure, said blood pressure means electrically coupled to said central processing unit, said central processing unit further comprising a means for displaying blood pressure.

6. A compact hand-held instrument for use in home or veterinary office applications for checking the vital signs of an animal comprising:

(a) a probe mounted at a first end to a handle display unit, said probe of a definite size and shape;

(b) at a second end of the probe away from said handle display unit, a thermistor electrically connected to a central processing unit contained within said handle display unit and a timer in said handle display unit;

(c) a battery within said handle display unit, electrical connections for said thermistor, said central processing unit, and said timer to said battery whereby electrical power is supplied as required and in said central processing unit means for calculating and displaying a temperature on said handle display unit, means for calculating an elapsed time and means for sounding an audible signal when a predetermined amount of a lapsed time has occurred;

(d) an adjustable cuff with a pulse transducer in said cuff, said transducer electrically connected to said central processing unit in said handle display unit, means for calculating a pulse in said central processing unit and means for displaying said calculated pulse on said handle display

whereby a user may take the temperature and pulse of an animal using said probe and adjustable cuff and use the timer to count respirations to determine a respiration rate.

7. A compact hand-held instrument for use in home or veterinary office applications for checking the vital signs of an animal of claim 6 wherein said probe is of a size and shape to be used with cats or small dogs.

8. A compact hand-held instrument for use in home or veterinary office applications for checking the vital signs of an animal of claim 6 wherein said probe is of a size and shape to be used with animals the size of a medium or large dog.

9. A compact hand-held instrument for use in home or veterinary office applications for checking the vital signs of an animal of claim 6 wherein said probe is of a size and shape to be used with horses or similar sized animals.

10. A compact hand-held instrument for use in home or veterinary office applications for checking the vital signs of an animal of claim 6 wherein said hand-held instrument further comprises means for detecting and displaying blood pressure.

11. A method for taking the vital signs of an animal comprising:

(a) placing a cuff around an extremity of an animal in proximity to an artery, in said cuff a transducer for sensing blood flow in said artery;

(b) attaching said cuff by electrical connections to a handle display unit, said handle display unit having a probe mounted at one end of said handle display unit, said probe containing a thermistor electrically connected to said handle;

(c) providing a central processing unit in said handle for calculation of a temperature and pulse and display of said temperature and said pulse on said handle display unit;

(c) placing said probe into a body cavity of an animal for a definite time whereby said thermistor may determine the body temperature of an animal;

(d) providing a timer and an alarm unit in said handle display unit so that an elapsed time of a definite duration may be calculated and an audible alarm sounded at the end of said definite time unit;

(e) counting respirations of said animal during said elapsed time and calculating a respiration rate for said animal

whereby an operator may determine the pulse of an animal by use of said cuff, the temperature of an animal by use of said probe, and the respiration rate of said animal by counting the respirations as assisted by said timer all to determine the vital signs of pulse respiration rate, and temperature.

12. A method for taking the vital signs of an animal of claim 11 further comprising placing a second cuff around an extremity of an animal in proximity to an artery, in said second cuff a means for sensing the blood pressure in said artery and a means for displaying said blood pressure in said handle display unit.
