摘要： An apparatus for dosing a liquid medicine has a balloon (1), a housing (3) and a delivery assembly `b`. The balloon receives and discharges a liquid medicine under pressure. The housing enclosing the balloon has an opening communicating with the assembly `b` in which a flow regulator (10) is installed. The balloon (1) is composed of flat and expansible sheets secured to both side rims of a short cylindrical frame (2). The flat sheets constituting the balloon are of an even thickness over their whole area, even after being inflated with the medicine, so that the pressure as well as the flow rate of the medicine effluent from the balloon will scarcely vary at the mouth over the course of time. Thus, the liquid medicine is dosed to a patient at a constant flow rate through the regulator.

摘要： A liquid medicine self-administration device including a flexible reservoir, an operating member, a pushing member to move with respect to the operating member and to induce pressure deformation of the reservoir, and engaging means engages the operating member. With the operating member engaged by the engaging means, the pushing member is relatively moved to the operating member based on restoring force of a spring member to push the reservoir by the pushing member. By disengaging means moving in unison with the pushing member, the engaging means is released from an engaged state with respect to the operating member, when the pushing member has moved to a predetermined location while pushing the reservoir.

摘要： A multi-stage type flow rate switching device is provided which simplifies switching of flow paths and which rarely causes erroneous operation. The multi-stage type flow rate switching device includes a constant flow rate path 2 and a variable flow rate path 3 arranged in parallel between a liquid medicine flow inlet port 1 and a liquid medicine flow outlet port 4 where the variable flow rate path 3 can change the flow rate by means of a three-way stopcock 33. Although the flow rate can be switched in four stages when one variable flow rate path 3 is arranged as shown by FIG. 1, the flow rate can be switched in further multi-stages by providing two or more of the variable flow rate paths 3.
