Endoscope reprocessor

An endoscope reprocessor includes: a first fluid supply section configured to supply a fluid to a forceps plug pipe sleeve of an endoscope; a second fluid supply section configured to supply a fluid to a suction pipe sleeve; and a control section, wherein the control section performs: first control of driving the first fluid supply section and the second fluid supply section at the same time; second control of driving the first fluid supply section such that a flow rate of the second fluid supply section becomes lower than a flow rate of the first fluid supply section; and third control of driving the second fluid supply section such that the flow rate of the first fluid supply section becomes lower than the flow rate of the second fluid supply section after the first control or the second control.

A liquid supply apparatus includes: a storing tank configured to store a liquid; a supply conduit through which the liquid remained inside the supply conduit flows reversely into the storing tank by a predetermined amount over time, the supply conduit having a first end portion connected to the storing tank; a liquid feeding section which is arranged at the storing tank or the supply conduit, and which is configured to feed the liquid from the storing tank to a second end portion of the supply conduit; a time measuring section which measures an elapsed time from stop of the liquid feeding by the liquid feeding section; and a control section which is connected to the liquid feeding section and the time measuring section and which is configured to drive the liquid feeding section for a predetermined time based on a length of the elapsed time.

Liquid supplying apparatus and endoscope reprocessing apparatus

Endoscope connection portions, a fluid feeding duct, a liquid supply duct, a pump, a first atmospheric exposure duct including one end connected to the fluid feeding duct and the other end exposed to atmosphere, a relief valve disposed at an intermediate position of the first atmospheric exposure duct, a first stop section disposed at an intermediate position of the first atmospheric exposure duct, and a control section that performs control to supply a liquid to ducts of endoscopes and controls at least opening/closing operation of the first stop section are included.

Endoscope cleaning/disinfecting apparatus

A medical system includes: a treatment instrument having an insertion portion configured by an exterior member, and an insertion member that is inserted into the exterior member and is longer than the exterior member; an insertion portion inserting/pulling-out device to transmit a driving force to the exterior member or the insertion member configuring the insertion portion of the treatment instrument, the insertion portion inserting/pulling-out device advancing/retreating at least one of the exterior member and the insertion member; and a driving force non-transmitting portion provided to the insertion member, the driving force non-transmitting portion preventing a driving force of the insertion portion inserting/pulling-out device from being transmitted to the exterior member when the insertion member is moved by a predetermined distance.

Medical system and endoscope system

The present invention includes a storing section that stores a chemical, an opening provided in an upper surface, a concave portion formed in a first side face, and an inclined face that is formed at a face on an upper surface side of the concave portion and that inclines towards the upper surface side. The center of the concave portion is positioned so as to deviate from the central axis at the first side face.

Chemical bottle for endoscope cleaning/disinfecting apparatus

A disinfecting chemical bottle includes a bottle body including a storing section that stores a chemical used for cleaning/disinfecting an endoscope and a mouth portion including an opening portion from which the chemical freely flows out, a first conductive portion provided so as to be exposed in an inner portion and an outer portion of the bottle body, and a second conductive portion provided at a position different from that of the first conductive portion so as to be exposed in the inner portion and the outer portion of the bottle body, the second conductive portion being electrically connectable to the first conductive portion via the chemical in the bottle body.

Chemical bottle for endoscope cleaning/disinfecting apparatus and endoscope cleaning/disinfecting apparatus

A treatment instrument operation unit is provided with a drive unit, an operation portion installation section and a command signal output section. The drive unit drives an operation portion for operating each treatment section of the respective treatment instruments. The operation portion is attached to the operation portion installation section provided to the drive unit. The command signal output section outputs an installation start signal to a controller for notifying that the installation of the treatment instrument has begun upon installation of the operation portion in the operation portion installation section. After outputting the installation start signal from the command signal output section to the controller, the drive unit drives the operation portion installation section to the position where the operation portion is allowed to be installed based on the control signal outputted form the controller.

Treatment instrument operation unit and medical system with treatment instrument operation unit

An apparatus is provided which assists operations required for a medical instrument. A tubular portion and a therapeutic member of the instrument are inserted through a channel of an insertion tube of an endoscope. In the apparatus, a first drive unit enables the therapeutic member to perform the desired therapeutic operations responsively to a first command signal and a second drive unit enables the tubular portion inserted in the channel to convey responsively to a second command signal. An input device is provided at which two kinds of commands are allowed to be inputted command by command. The two kinds of commands allow the therapeutic member and the tubular portion to be driven in parallel with each other. A controller provides the first and second drive units with the first and second command signals, respectively, in accordance with the two kinds of commands.

Apparatus for assisting operations of medical instrument attached to endoscope

An endoscope cleaning/disinfecting apparatus connector according to the present invention includes a cleaning/disinfecting apparatus connection section, a circulating section and a discharge section, wherein the discharge section communicates with the circulating section and includes a first channel that discharges a fluid R that passes through the circulating section into a pipe sleeve, a second channel that branches from the first channel and discharges the fluid R to the periphery of the pipe sleeve, and an opening/closing section that is provided in a branch section that branches from the first channel to the second channel or in the second channel, is freely expandable/contractible according to a flow rate of a fluid and blocks the second channel when the flow rate of the fluid is a predetermined amount or higher.

Endoscope cleaning/disinfecting apparatus connector and endoscope cleaning/disinfecting apparatus
