A small, light and inexpensive pocket flicker (P.F.) apparatus for measuring fatigue was designed, fabricated and tested. The apparatus, being composed of a light emitting diode and a variable resistor with a scale, is so compact that it can be carried in a shirt pocket. Thus, critical fusion frequency (CFF) values can be easily determined at a working place and the load involved is small when compared to other physical fatigue measurements and earlier CFF apparatuses. Moreover, the apparatus is so inexpensive that it can be widely used. To compare the performance of the P.F. apparatus with earlier apparatuses, the following experiments were performed. CFF values were measured at the same time with the pocket type apparatus, blinking type apparatus and sector type apparatus and the results were compared. The subjects were 13 males and 5 females with their age ranging from 21 to 52 years. The total number of measurements was 132. The CFF values measured with these three apparatuses showed a significant correlation. The correlation coefficient between the CFF values measured with the sector type apparatus and blinking type apparatus was high, but the slope of the regression line was not one. Hence, in comparing the values measured with another apparatus, we should be aware of the differences between these data. The correlation coefficients between the CFF values measured with P.F. apparatus and with sector type apparatus or blinking type apparatus were not higher than those between the CFF values measured with sector type apparatus and blinking type apparatus.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

A cigarette-smoke dosage apparatus for controlled smoke dosages is constructed particularly for rodents. This apparatus can be adapted to their oral cavity, in which a minimizing of the distance between the cigarette and the oral cavity is obtained. The construction and characteristics of the apparatus is presented. The apparatus can be used in studies concerning the effect on lung clearance of cigarette smoke with or without simultaneous exposure to different air pollutants. 相似文献

An apparatus for automatic lung straightening may be used in medical technologies employed in thoracic (lung) surgery in the postoperative rehabilitation of a patient. This apparatus may automatically (without a physician's or a nurse observance) maintain tension relief in the pleural cavity in the patient on an individual basis, which is required for complete lung strengthening. Its use greatly reduces the number of postoperative complications in the lung, such as residual cavities, edema, and empyema of the pleura. This apparatus is to go into quantity production as a cheap, expendable device to prevent AIDS and hepatitis. 相似文献

AIM. To evaluate an apex locator in determining the working length of root canals and detecting micro-communications with the pulp chamber. METHODS. The apparatus was tested on 21 patients, aged 18 - 70, who received endodontic treatment of 34 teeth with 45 root canals. The apparatus was used in compliance with the instructions of the manufacturer. The precision of the instrument was determined by a radiograph of the tooth with a file inserted in it at a depth equal to the length determined with the Apex locator. The obtained results were divided into three groups: canals determined as longer; canals in which the outline of the instrument was close to the roentgenologic apex; and canals determined as shorter. CONCLUSION. The average deviation from the roentgenologic apex was 1.17 mm, which is, in fact, the area of the physiological apex opening - the ideal limits for treatment and obturation. The apparatus can be successfully used to make differential diagnosis is useful of deep caries with pulpitis chronica ulcerosa. It is ergonomic and easy to use. 相似文献
