Handheld gas spray systems for mixing and dispensing multi-component compositions.

A device for delivering an agent may comprise: a housing defining an enclosure. The housing may be configured to store an agent. The device may further comprise an inlet, in fluid communication with the enclosure, for receiving a flow of pressurized fluid; an outlet in fluid communication with the enclosure; and a filter disposed within the enclosure. Pores of a wall of the filter may be configured such that the fluid is permitted to pass through the pores into a channel defined by an inner surface of the wall. An actuation member may be configured to transition between a first configuration, in which portions of the agent disposed proximally to the actuation member are prevented from passing distally of the actuation member, and a second configuration, in which portions of the agent disposed proximally of the actuation member are capable of passing distally of the actuation member.

An aerosol spray device includes a container having first and second fluid reservoirs disposed therein that are divided from one another. The first fluid reservoir holds a first mixture including a first aerosol propellant and a first part of a silicone based topical skin adhesive that is dissolved in the first aerosol propellant. The second fluid reservoir holds a second mixture including a second aerosol propellant and a second part of the silicone based topical skin adhesive that is dissolved in the second aerosol propellant. An aerosol spray dispensing system is connected with the container, which is configured to combine the first and second mixtures to form the silicone based topical skin adhesive and dispense the silicone based topical skin adhesive from the container as an aerosol spray.

A medical device that includes a body configured to store a first substance and a second substance, a shaft extending distally from the body and having a distal end, and a pressure source in fluid communication with the first substance, the second substance, and the shaft. Pressurized medium from the pressure source is configured to deliver the first substance through the shaft and out of the distal end, deliver the second substance through the shaft, separate from the first substance, and out of the distal end, and be delivered through the shaft separate from the first substance and the second substance, and out of the distal end. The pressurized medium mixes the first substance and the second substance externally of the shaft as the first and second substances exit the distal end.

A clotting agent delivery system comprises a frame, a passageway extending along the frame, a discharge opening connected to the passageway, a clotting agent reservoir fluidly connected to the passageway to hold a clotting agent substance, a valve in the passageway to control flow of the substance through the passageway, and an actuator to allow propellent to flow into the passageway, wherein the valve and clotting agent reservoir cooperate to provide clotting agent substance to the discharge opening at constant pressure using the propellant. A method for delivering a clotting agent comprises inserting a delivery catheter into an anatomic area, coupling a clotting agent delivery system to the delivery catheter, the clotting agent delivery system having a reservoir of a clotting agent, operating a valve to release propellant for propelling the clotting agent, and conveying the propellant and the clotting agent to the delivery catheter at a constant pressure.

An adapter manifold having an adapter body and a syringe applicator, wherein the adapter body has substantially parallel inlet ports and substantially parallel exit ports, the inlet ports spaced an axial distance apart which is different from an axial distance between the exit ports, to accommodate the syringe applicator which has multiple substantially parallel syringes, and substantially parallel syringe connectors in fluid communication with the inlet ports having Luer-type receivers on proximal ends thereof, wherein the syringe connectors are biased toward a proximal end of the adapter body.

A powder spray device includes a funnel member, a first three-way joint, an air-current supply tube, a discharge tube, a vibration motor, a bypass air-current tube, and a switching mechanism. The first three-way joint has a first opening connected to an outlet at a lower end of the funnel member. The air-current supply tube and discharge tube are respectively connected to second and third openings of the first three-way joint. The vibration motor is fixed onto an outer surface of a funnel body of the funnel member. The bypass air-current tube branches off from the air-current supply tube and is connected to the discharge tube. The switching mechanism switches from and to standby state, in which compressed gas is sent only through the bypass air-current tube, to and from spray-coating state, in which compressed gas is sent out through the air-current supply tube, and also through the bypass air-current tube.

A medical device including an application device with a first fluid path and a container movably attached to the application device. The container and the application device have a second fluid path therethrough, the container includes an inner chamber that is intermediate proximal and distal portions of the second fluid path, the inner chamber is fluidly isolated from the proximal portion of the second fluid path at a first position of the container, and the inner chamber is fluidly coupled to the proximal and distal portions of the second fluid path at a second position of the container. The first fluid path bypasses the container and the passage of fluid through the first fluid path is separately controllable from the passage of fluid through the second fluid path.

Proposed is a hemostatic sprayer for stopping a flow of blood from a bleeding portion of the human body, the hemostatic sprayer including a powder casing inside which an accommodation space is formed and which includes inlet and outlet ports, hemostatic in the form of powders being pre-stored in the accommodation space, and the inlet and outlet ports connecting thereto, and a receptacle inside which gas is compressed and pre-stored and which has a supply port on one side, the supply port separably connecting to the inlet port, wherein the supply port is open as a result of pressing by the powder casing, wherein, through the open supply port, the gas is supplied with a preset pressure toward the inlet port and flows into the accommodation space through the inlet port, and wherein the gas flowing is discharged together with the hemostatic through the outlet port while scattering the hemostatic.

The present disclosure relates to an in vivo duct repair device and an operating method thereof. The in vivo duct repair device includes a catheter; a nozzle assembly, two axial ends thereof including a supplying end and a spraying end, respectively, the nozzle assembly having a first material flow channel arranged inside the nozzle assembly, a first material spout communicated with the first material flow channel and spraying a first material radially outwards, a second material flow channel arranged inside the nozzle assembly and isolated from the first material flow channel and a second material spout communicated with the second material flow channel and spraying a second material radially outwards, and the nozzle assembly being configured to enter the catheter and extend the spraying end out of an introducing end of the catheter; and a drive device connected to the supplying end.
