Syringe backstop

In a connection device, when a cannula holding member is in a use state, a position of an end portion of an outer cylindrical portion on a retracted position side does not protrude to the retracted position side, with respect to a position of an end portion of an inner cylindrical portion on the retracted position side. Thereby, a connection device including a structure capable of holding a vial by holding means irrespective of the size of the vial can be provided.

Connection device

The invention is configured so that pressurized gas from a pressurized gas supply source passes through a pressurized gas channel provided in a main body of a powder spraying device and is sprayed out. A powder container containing powder such as medical agents is provided on the main body. The powder within the powder container is supplied to the pressurized gas channel and is sprayed together with the pressurized gas. An eccentric rotor with a center of gravity deviated from a center of rotation is provided in the main body. When spraying the powder together with the pressurized gas, vibrations are applied to the main body and the powder container by a rotation of the eccentric rotor. The powder can be thereby mixed more evenly with the pressurized gas.

Powder spraying device

An administration device can discharge a prescribed, equal amount of medicine a number of times by spraying. A spraying device includes a barrel; a gasket provided slidably movable in liquid-tight manner in the barrel; a rod coupled to a base end of the gasket; and a regulating member provided on the barrel, having a projection that can slidably fit with the guide groove. The guide groove includes at least first and second continuous administering grooves. The second administering groove is configured to include a transitional portion extending in the circumferential direction with a groove wall on the base end side aligned with the base end of the first administering portion, and a second administering portion extending from the transitional portion to a base end along the longitudinal direction. An energizing protrusion engageable with the projection is provided at a boundary between the transitional portion and the second administering portion.

Spraying device

A nasal cavity administration container includes a body section including a medical fluid storage section having an opening and a plunger having a pressing part, and a plunger moving amount regulation member having a stopper and being engaged with the body section, an engagement with the body section being relieved only in a state where the pressing part abuts on the stopper. When the plunger is pushed into the medical fluid storage section, the plunger moves forward until the pressing part abuts on the stopper. The plunger is further pushed into the medical fluid storage section with the plunger moving amount regulation member detached from the body section. The nasal cavity administration container can administer a medical fluid easily and appropriately.

Nasal cavity administration container

A liquid agent container includes the container's main unit, a cap, an intermediate member, and an internal stopper. The cap is provided with a liquid agent discharging path and an air introducing path. The intermediate member has a tube projecting toward the interior of the main unit. Between a liquid agent introducing path and the liquid agent discharging path a hydrophilic filter is provided, and between an air supplying path communicating with the air introducing path and an air delivering path a filter is provided. The air delivering path communicates with the interior of the main unit via a check valve, with an annular valve having an inner circumferential surface in contact with an outer circumferential surface of the tube, to pass air only in a direction toward the interior of the main unit. The present invention can provide a liquid agent container including a check valve readily fabricated and ensuring preventing a liquid agent from flowing back.

Liquid agent container

A connection device includes a main holder including a syringe holder to be attached to a syringe and a cannula holder which includes a double-head cannula. The cannula holder is located at a retracted position retracted with respect to the syringe holder in the pre-use state, and is advanced to an advanced position abutting on the syringe holder in the use state. The connection device further includes a separation preventing mechanism which engages the syringe to prevent separation of the syringe from the syringe holder in the state where the cannula holder is located at the retracted position. When the cannula holder is located at the advanced position, the separation preventing mechanism releases an engagement state with the syringe to permit the separation of the syringe from the syringe holder.

A transfer needle comprises: a liquid-specific member; and a medicament-specific member to be separably connected or joined to the liquid-specific member in a liquid-tight state. The liquid-specific member comprises: a liquid-specific hollow needle projecting toward the opposite side from the medicament-specific member. The medicament-specific member comprises: a medicament-specific hollow needle projecting toward the opposite side from the liquid-specific member and communicating with the liquid-specific hollow needle. A female luer is provided on at least one of the liquid-specific member and the medicament-specific member at a position opposing to the other. The female luer communicates with the one hollow needle and is separably connected with an injection needle connecting portion of a syringe in a liquid-tight state.

Transfer needle

A liquid drug container comprises a container body; a nozzle memberliquid-tightly mounted on the container body; and a nozzle capfitted on the nozzle member. A nozzle holeof the nozzle memberis covered with a hydrophilic filer, and a top wall of the nozzle memberis provided with an air holecovered with a hydrophobic filter. The nozzle membermay be provided with a filter-mounting memberfor attachment of the filters. Also, the nozzle membermay be provided with a flow control member that controls air flowing into the container body through the air hole.
