Laboratory leukocyte counter LC-1

Blood leukocyte counting counter LC-1 is designed for counting different types of blood cells (leukocyte formula) during its microscopic examination. Leukocyte counter LC-1 is used in laboratories of polyclinics, hospitals, research institutes and other medical institutions.

DEVICE AND OPERATING PRINCIPLE OF THE COUNTER:

The mechanism of the counter LC-1 is assembled in the base of the body, in the side walls of which the shaft is fixed. Ten digits (from 0 to 9) are printed on the cylindrical surface of the digital drums at regular intervals. There are teeth on the end of the drum along the circumference. There is a leaf spring inside the drum. There are groups of drums showing three-digit numbers on the shaft. Each group has its own lever with a dog. The pawls are pressed by springs to the teeth of the drums. On the ends of the levers, located on the axis , the keys are fixed. Eight keys of the laboratory counter for counting the leukocyte formula of blood LC-1 are used for counting certain blood cells. The lever with the doggie also interacts with the drums in the "AMOUNT" window, which sums up the total number of counts. Each time the key is pressed all the way down, the unit drum rotates by 36°, i.e. one unit. After the ninth key is pressed, the first tooth of the dog, which rotates the unit drum, enters the slot. The second tooth of the dog enters into engagement with the drum of tens. When the key is pressed for the tenth time, both the drum of units rotates and the drum of tens rotates, showing the number "0" and the number "1". Similarly, with each hundredth key press, the third tooth of the dog rotates the drum of hundreds by one. The lever automatically sums the total number of all counts at each count. At every one hundred total counts, the striker will give a signal by striking a bell. The levers are reset by springs. The leukocyte counter is reset to zero by turning the knob.
