Abstract:
1. A powder medicine administering apparatus comprising: an upper body including a lower surface, and a medicine storage chamber having an upper opening portion opened on the lower surface, and storing a powder medicine; a lower body including an upper surface, and a medicine receiving chamber which has a lower opening portion, and which is recessed in a downward direction from the lower opening portion, the lower body being relatively pivoted with respect to the upper body about a pivot axis so that the lower surface of the upper body is slidably moved on the upper surface of the lower body to be switched between a connection state in which the upper opening portion of the upper body is connected with the medicine receiving chamber of the lower body, and a non-connection state in which the upper opening portion of the upper body is not connected with the medicine receiving chamber of the lower body, the medicine storage chamber of the upper body being arranged to supply the powder medicine through the upper opening portion of the upper body to the medicine receiving chamber of the lower body in the connection state, the upper body being arranged to level the powder medicine supplied to the medicine receiving chamber by the relative slide movement of the upper body and the lower body, the medicine receiving chamber being moved from a standby position to a discharge position in which the medicine receiving chamber is connected with an air passage to discharge the powder medicine with air, the medicine receiving chamber being arranged to be moved in one section from the standby position to the discharge position so that the entire lower opening portion of the medicine receiving chamber is within the upper opening portion of the upper body, wherein the medicine receiving chamber is moved back and forth in the one section from a previous discharge position through the standby position to a next discharge position so that the entire lower opening portion of the medicine receiving chamber is within the upper opening portion of the medicine storage chamber, and wherein the medicine receiving chamber reaches the next discharge position after a first stroke, in which the medicine receiving chamber is moved from the previous discharge position to a return position so as to be switched from the non-connection state through the connection state to the non-connection state by passing the medicine receiving chamber below the upper opening portion of the medicine storage chamber by the relative slide movement of the upper body and the lower body to supply and level the powder medicine, and a second stroke, in which the medicine receiving chamber is moved from the return position to the next discharge position to be switched from the non-connection state through the connection state to the non connection state by passing the medicine receiving chamber below the upper opening portion of the medicine storage chamber by the relative slide movement of the upper body and the lower body to supply and level the powder medicine, and which is in a direction opposite to the first stroke.
