Abstract: A relaxation oscillator includes a start-up circuit. During the start-up period of the relaxation oscillator, two output signals from the relaxation oscillator are controlled to be complementary signals by the start-up circuit according to a control signal. Consequently, the relaxation oscillator can be started up successfully. The relaxation oscillator can generate periodic square wave signals. Moreover, during the start-up period of the relaxation oscillator, the generation of the deadlock situation can be avoided.

Abstract: A clinical specimen detector includes a clip having a clamping end and a pressing end; and wherein a pair of compressing slices are disposed on the clamping end, and a channel is disposed in the lower end of at least one of the pair of compressing slices. A detecting reagent test chip is attached to the outer surface of the compressing slice. The lower end of the detecting reagent test chip is substantially aligned with and is adjacent to the channel. The lower ends of the compressing slices clamp an adsorptive material adsorbed with body fluid such that the body fluid can be released from the adsorptive material because of the compression of the compressing slices and can be delivered to the lower end of the detecting reagent test chip via the channel, so as to perform disease testing and physiological condition testing with the detecting reagent test chip.

Abstract: The present invention discloses a clinical specimen sampler, including a filtering device; and a sampling device. The sampling device includes a sampling adsorber and a rod. The sampling adsorber is connected with one end of the rod, and the sampling adsorber is encompassed in the filtering device. The sampling adsorber is utilized to absorb the body fluid secreted by the intima of an organ, and the filtering device is employed to prevent the mucosal tissue of the intima of the organ from entering the sampling adsorber and enable the body fluid secreted by the intima of the organ to enter the sampling adsorber, so as to be absorbed by the sampling adsorber.
