The invention discloses a double-faced sound production wall map, an implementation method thereof and a double-faced button implementation circuit and method. The double-faced button implementation circuit comprises a first printed circuit, a second printed circuit and an insulation layer. The first printed circuit is provided with N first contacts, a first switch contact and a second switch negative electrode contact; the second printed circuit is provided with N second contacts, a second switch contact and a first switch negative electrode contact. The first contacts are arranged on X first guide lines, and the second contacts are arranged on Y second guide lines. The insulation layer is clamped between the first printed circuit and the second printed circuit. Through holes are formed in the positions opposite to all the contacts. The first switch contact and the second switch contact are pressed to generate a first selection signal and a second selection signal respectively. The first contact and the second contact are pressed to generate a first using signal and a second using signal respectively. A control unit recognizes the states of the corresponding first contacts and the states of the corresponding second contacts through the first selection signal, the second selection signal, the first using signal and the second using signal. The double-faced sound production function of the wall map is achieved, the voiced teaching contents are enriched, and the space utilization rate of products is improved.

The invention discloses a showcase for marketing major education in the technical field of marketing education, which comprises vertical plate, a case body, a rotating frame and a display plate. Through classifying and placing the articles to be displayed on the display plate and a rotating plate of the rotating frame, the commodity storage amount and type in the showcase are improved, the teaching content of a teacher is enriched; the rotating frame can always keep rotation through the driving of a third motor, thus the products on the rotating plate are comprehensively displayed and convenient to check, the learning initiative of students can be improved; the bottom part of the display plate is sleeved with a second screw bar through a fixing block, the display plate can forwards move along the second screw rod through the rotating second screw bar, thereby facilitating teachers and students to check and learn about displayed products and improve the teaching quality and effect; whencommodities are not required to display, the case bodies at both sides can rotate inwards in relative to the slide block at the top end through the second motor and the fixing shaft; then the slide block drives the case body to move towards inside through the first screw rod, thus the case bodies at both sides are folded and convenient to place and move.

An intelligent capacity therapy instrument includes a central processing unit, an internal storage device, a power supply device, a keyboard device, a display device, an alarm device, an input control circuit, a monitor interface, a fluid velocity monitor and a fluid velocity controller. The internal storage device is used for storing program instructions and the volume treatment decision-making plan for the perioperative period and records of patient volume treatment pre-stored by the central processing unit. According to the patient-related information input by the keyboard device, the central processing unit extracts the corresponding volume treatment decision-making plan from the internal storage device for processing and formulates the patient's preliminary volume treatment plan; executes the patient's volume treatment plan according to the working mode selected by the doctor; The patient's physiological parameters transmitted by the monitor are automatically fed back to adjust the volume therapy plan, and the patient's volume therapy record is stored in the internal storage device; according to the obtained signal for determining the infusion rate, the infusion rate is monitored in real time and fed back to correct the infusion rate.
