Description

Medical educational is used electric chart

(1), technical field: the utility model relates to a kind of electric chart, and particularly a kind of medical educational is used electric chart.

(2), background technology: the medical professionalism professorship education be directly for produce, serve and manage a line post cultivate down go, stay the high professional qualification type talent's that lives, can use education.In the existing medical educational student's book knowledge is had relatively high expectations; And cultivate inadequately to student's practical operative ability; Do not demonstrate fully the characteristics of Higher Occupational Education, the graduation student gets into clinical post can not be competent at concrete work at once, has departed from the training objective of professorship education.In order to cultivate student's actual operational capacity, in teaching process, just should strengthen the exercise of operating aspect, but it is also few to have the teaching aid that is used for the operation practice aspect now, and most function singleness, not too be fit to teaching and use.Such as: widely used medical knowledge wall chart in imparting knowledge to students now, it can increase the understanding that the student divides organ to the partes corporis humani, but its form of expression is more single, is unfavorable for cultivating students'interest in learning and strengthens students'ability for practice and creativity.

(3), the utility model content: the technical matters that the utility model will solve is: not enough to prior art, provide that a kind of function is strong, the form of expression vividly intuitively medical educational use electric chart.

The technical scheme of the utility model: a kind of medical educational is used electric chart; Contain translucent wall chart paper and control circuit; Be printed with medical educational figure on the front surface of wall chart paper; Contain N study position on the medical educational figure, on the back surface of wall chart paper and corresponding each place, study position N luminous indicating lamp and N tactile sensor are installed respectively, the input end of control circuit is connected with N tactile sensor; The pilot lamp output terminal of control circuit is connected with N luminous indicating lamp, and N is the natural number more than or equal to 1.

Control circuit contains microprocessor, a N touch perception circuit; N tactile sensor is connected with N input end that touches the perception circuit respectively; N output terminal that touches the perception circuit is connected with N input end of microprocessor, and the signal of the N of microprocessor pilot lamp output terminal amplifies N luminous indicating lamp of rear drive through triode respectively.

Each touches the perception circuit and contains first electric capacity, second electric capacity, the 3rd electric capacity, first resistance, second resistance, first diode, second diode; Tactile sensor is connected with the frequency output terminal of microprocessor through first electric capacity; Tactile sensor also is connected with the negative pole of first diode, the positive pole of second diode through second electric capacity; The plus earth of first diode; The negative pole of second diode is through the parallelly connected ground connection of second resistance and the 3rd electric capacity, and also through first resistance eutral grounding, the negative pole of second diode is connected with the input end of microprocessor tactile sensor.

Luminous indicating lamp is the LED luminotron, and the model of microprocessor is 89C2051.

Also contain voice module in the control circuit, the speech output end of microprocessor is connected with the input end of voice module, and the output terminal of voice module connects loudspeaker.

The beneficial effect of the utility model: 1. the utility model each study position on medical educational figure is equipped with luminous indicating lamp and tactile sensor; When the operator touches this study position with hand; This study position can be luminous, broadcasts the specific descriptions of announcer to this learning section bit position, form and structure simultaneously in the loudspeaker.This electric chart sound spectrogram is also luxuriant, residence is learned in pleasure; With Ju not the lively mode of lattice; Let the student in cheerful and light-hearted atmosphere, initiatively learn and grasp each organ of human body unawares, improved students'interest in learning, strengthened students'ability for practice and creativity.
