EOFLOW CO., LTD.

A method of disconnecting an electrical connection between a control module included in a medical liquid infusion apparatus and an internal device electrically connected to the control module, the method includes: bringing a tool into contact with a fracture portion formed to protrude outward from one side of the control module and having a control line formed therein; applying, by the tool, an external force to the fracture portion to fracture the fracture portion; and fracturing the control line by fracturing the fracture portion to disconnect the electrical connection between the control module and the internal device.

A medical liquid infusion apparatus includes: a first body to which a needle assembly is mounted, a control module installed in the first body, configured to control driving of the needle assembly, and electrically connected to an internal device, and a fracture portion formed to protrude outward from one side of the control module, and fractured by an external force to allow an electrical connection between the control module and the internal device to be disconnected.

A medical liquid injection device is provided. The medical liquid injection device includes a base body, a needle assembly mounted on the base body, a reservoir fluidly connected to the needle assembly and having a guide groove on an inner surface, and a driving unit configured to move a plunger disposed inside the reservoir.

A method and apparatus for determining an inactive time of a medical liquid dose calculator are provided. According to the method, an infusion error of a medical liquid infusion device may be detected, and an inactive time of the medical liquid dose calculator may be determined in response to detection of the infusion error.

A medical liquid discharge assembly includes: a driving part configured to move in a preset direction, a rotating part configured to come into contact with the driving part, and to rotate in one direction in response to the movement of the driving part, a tube part disposed adjacent to the rotating part and including a flexible material, a pressure-applying part configured to come into contact with the rotating part, and to come into contact with and apply pressure to the tube part in response to the rotation of the rotating part, and a locking part configured to move in a preset direction, and to fix a position of the pressure-applying part by coming into contact with and supporting one surface of the pressure-applying part while the pressure-applying part applies pressure to the tube part.

A medical liquid injection device includes: a reservoir assembly storing medical liquid in a storage space defined by a reservoir and a plunger moving linearly inside the reservoir, a needle assembly connected fluidly to the reservoir assembly to discharge the stored medical liquid, and a driving unit transmitting a driving force generated by a driving module to the plunger. The driving unit includes a rod member coupled to the plunger to move linearly together with the plunger, a wheel member rotating by the driving force, and a connection member having a catching portion that is movable in an axial direction of the wheel member and the rotation thereof with respect to the wheel member is limited around the axial direction.

The disclosed technology relates to a method for using a medicinal fluid injection device comprising a housing having an opening in a side surface thereof, a storage container arranged inside the housing and configured to store a medicinal fluid, an injection needle connected to the storage container and configured to inject the medicinal fluid when stored in the storage container through the opening, and a cover body covering the opening, wherein the cover body includes a cover part configured such that the a shape of the cover part changes according to air pressure caused by the injection needle.

A Liquid medicine injection apparatus includes: a needle portion having one or more needle bodies configured to be injected into a user's body, a reservoir portion configured to accommodate a medical liquid and receive power from a driving portion to deliver the medical liquid to the needle portion, a base portion on which the reservoir portion, the needle portion, and the driving portion are installed, a cover portion covering the base portion, and a sensor portion configured to measure blood sugar. In the cover portion, an insertion groove which has one side open and has a preset depth is formed, and the sensor portion is insertable into the insertion groove and is spatially separable from the base portion.
