The nursing device has a reasonable structure, and can rapidly realize pulse measurement and infusion dripping speed count and immediately display measurement results on a display screen with numbers.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments.
Background technology
Clinically, transfusion is the important channel and the base therapy method of clinical administration, the desired transfusion speed of all ages and classes, various disease and different pharmaceutical is complete difference, requires transfusion speed slower as old people and cardiac disorder person, and shock and dehydration patient require transfusion speed very fast; The speed of dripping of vasoactive agent requires transfusion speed very accurate.The nurse generally is to see that by the nurse table counting regulates when making an inspection tour the ward and observe transfusion speed or change liquid, need at least 15-30 second time or even more, could be clear dripping fast number, its shortcoming is time-consuming, inaccuracy and expense manpower.
Pulses measure comprises instantaneous pulses measure and average pulse measurement, and clinical common employing average pulse is measured, the speed of reflection heart rate, and record is convenient.Traditional manual pulses measure error is bigger, consumption manpower consuming time, and can't realize Real Time Observation.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructurely, easy to carry, can realize patient's pulses measure, transfusion drip speed counting rapidly, and on display screen, show the care device of measurement result immediately with numeral.
Technical solution of the present invention is:
A kind of care device, it is characterized in that: comprise support, pulses measure mechanism is set on the support and drips speed measuring device, described pulses measure device comprises first infrared transmitting tube, first photoelectric receiving tube that is arranged on the support, lays respectively at position, patients fingers to be measured both sides, first photoelectric receiving tube is connected with first amplification and rectification circuit, amplification and rectification circuit is connected with A/D converter, and A/D converter is connected with computer, and computer is connected with the LED display device; Described speed measuring device comprises second infrared transmitting tube, second photoelectric receiving tube that is arranged on the support, lays respectively at Mo Feishi pipe to be measured position, both sides, second photoelectric receiving tube is connected with second amplification and rectification circuit, second amplification and rectification circuit is connected with A/D converter, A/D converter is connected with computer, and computer is connected with the LED display device.
The involutory form of sheet about support is, and the groove of placement patient finger to be measured and the groove of placement Mo Feishi pipe are set at involutory position.
The present invention is rational in infrastructure, will drip the mancarried device that speed combines with pulses measure, and outward appearance is light and handy, the nursing staff is in making an inspection tour the ward process, it is precious to carry nursing, can realize patient's pulses measure, transfusion drip speed counting rapidly, and show measurement result with numeral immediately on display screen.The present invention plays an important role in clinical, under the few situation of the big or middle night shift nursing staff of clinical nursing activity amount, can improve nurse's work efficiency greatly especially, guarantees nursing safety, reduces the generation of medical tangle.The present invention is with low cost, outward appearance is light and handy.In light weight, volume is little, low in energy consumption, stable and reliable operation easily realizes, it is simple to operation to carry, clear display, and is convenient and practical.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is a fundamental diagram of the present invention.
The specific embodiment
A kind of care device, comprise support 1, pulses measure mechanism is set on the support and drips speed measuring device, described pulses measure device comprises first infrared transmitting tube 2, first photoelectric receiving tube 3 that is arranged on the support, lays respectively at position, patients fingers to be measured both sides, first photoelectric receiving tube is connected with first amplification and rectification circuit 4, amplification and rectification circuit is connected with A/D converter 5, and A/D converter is connected with computer 6, and computer is connected with LED display device 7; Described speed measuring device comprises second infrared transmitting tube 8, second photoelectric receiving tube 9 that is arranged on the support, lays respectively at Mo Feishi pipe to be measured position, both sides, second photoelectric receiving tube 9 is connected with second amplification and rectification circuit 10, second amplification and rectification circuit is connected with A/D converter 5, A/D converter is connected with computer 6, and computer is connected with LED display device 7.
The involutory form of sheet about support is, and the groove 11 of placement patient finger to be measured and the groove 12 of placement Mo Feishi pipe are set at involutory position.
Operation principle of the present invention is:
Pulses measure adopts optical method, and its principle is to detect the variation of blood to absorbing amount.Because beating of heart causes that little blood volume of finger fingertip takes place by corresponding the variation, its arterial blood changes with arteriopalmus the absorbtivity of light.The infrared light that infrared transmitting tube sends see through finger fingertip on the photoelectricity adopter to the signal of telecommunication that changes with arteriopalmus, amplify the pulse wave signal of the voltage form of output and finger tip blood volume-variation linear relationship through signal.By A/D converter digitized pulse wave signal is delivered Computer Processing.And the pulse wave signal after will handling shows (inferior/minute) with 3 decimal numbers on the LED charactron.
Drip speed and measure the same optical method that adopts:
A pair of infrared emission adopter places the both sides of Mo Feishi dropper respectively, when the drop that drips passes through pipe, infrared light is blocked, so on adopter, produce a disabling signal, this signal delivers digitized pulse wave signal to Computer Processing by amplify handing over A/D converter, and the fast signal after will handling shows (inferior/minute) with 3 decimal numbers on the LED charactron.
