  • Patent number: 8562209
    Abstract: The invention discloses a method to control the work of electronic thermometer by using the position of probe. The probe incased in a disposable sheath, wherein the pre-heating mechanism in the probe and the control switch is connected with the host of the electronic thermometer by wires; and by using the axial reciprocating motion of the probe to trigger the control switch to initiate the electronic thermometer. When using the invention, we use the movement for the assembling of the sheath to initiate the hearting process and measurement, to ensure that the disposable sheath is assembled on the probe, and then execute the measurement, so as to eliminate the possibility of cross infection completely. The invention also exempts the requirement for the users to the return back of the probe into the cavity after use, and brings convenience for the users: Meanwhile, the equipment structure is simple, and the machinery assembles are few by comparison, which effectively decrease the production cost.
