RESUMEN

Objective:To design a simple, energy saving, environmental protection, safety of the use of a new type of medical lamp with infrared light disinfection.Methods: Set the controller in the middle of the upright column of lamp, the controller side is provided with a flexible hose, and the end of the flexible hose is provided with a patch, the patch is placed in the patient's side. The back side of the skin is provided with a temperature sensor, a controller and a temperature sensor and a baking lamp. The controller is provided with an alarm, when over temperature will alarm.Results: The new type of infrared light disinfection and baking lamp is reasonable structure, mobile convenience. The alarm can automatically turn off the lights and alarm when the chip temperature is too high.Conclusion: The developed lamp device has the advantages of convenient use, strong practicability and long service life. It’s very worthy of promotion.

RESUMEN

Laparoscopic minimally invasive surgery technology is rapidly developing in the tumor treatment field. Due to the lack of space perception of the previous 2 D laparoscopic surgery, it has been unable to meet the current needs, and then 3 D laparoscopic technology emerged and got widely development. This paper summarizes the difference between the 3 D laparoscopic technique and traditional 2 D laparoscopic technology, and then analyzes the classification of 3 D signal display technology and common format. At the same time, this paper introduces the integration operating room structure with 3 d technology, signal format, and signal transmitting method. Finally, this paper prospected the application foreground for 3 D laparoscopic technology in the operating room.

RESUMEN

Objective:To develop a new type of biopsy sampling device which is usable, easy practice and has long service life.Methods:Pneumatic alarm device is added to the traditional biopsy system. During the process of doctor draw piston stem, when the syringe tube was blocked, air can drive the sealing cover open due to the external pressure is greater than the pressure of the cylinder, it is from the holes into the cylinder body to maintain the pressure balance and trigger the air alarm device alarm; when cylinder pressure restored normally, rod drives the sealing cover is closed under the action of the spring.Results: The new system is able to control the biopsy sampling pull the speed of the piston stem, and can automatically exhaust and alarm on the needle plug.Conclusion: The utility model has the advantages of convenient use, strong practicability and long service life. It’s worthy of popularization.

RESUMEN

Objective:To analyze the relationship between the concentration of glucose and the impedance of human blood, and study the relationship between human blood glucose detection and human blood impedance.Methods:The system adopts the AD5933 digital frequency synthesizer (DDS) in the excitation signal is produced, imposed on the impedance under test, the ADC acquisition signal and sent to the corresponding chip DFT digital processing module, measurement results through the I2C sent to the microcontroller, again by the single-chip microcomputer and PC computer communication, the computer shows that the impedance values. Results:The instrument can realize the resistor, capacitor, inductance, glucose solution impedance measuring rapidly and accurately, through experimental verify that resistive impedance deviation from the mean is 0.04, phase deviation from the mean is 0.15°.Conclusion:The glucose concentration of aqueous solution was linearly correlated with the impedance, the correlation coefficient greater than 0.99.
