Hand-held gaseous injector assembly for delivering therapeutic gas
A recently granted patent (Publication Number: US11771593B2) describes a hand-held gaseous injector assembly designed to deliver therapeutic gas to a patient. The assembly includes a syringe body with an outlet and a plunger that defines a first chamber within the syringe body. A second chamber, containing a pressurized fluid, is connected to the first chamber through a channel and an aperture. An activation system releases the fluid from the second chamber into the first chamber.
The assembly also features an adjustable volume limiter that allows the user to select different volumes for the first chamber. A filter, connected to the outlet of the syringe body, removes impurities from the gas. A flow restrictor, connected to the filter, controls the flow of the gas from the first chamber to the exterior of the assembly. The flow restrictor generates back pressure, expanding the first chamber to the desired volume set by the adjustable volume limiter.
In one embodiment, the filter is removably connected to the syringe body, allowing for easy replacement. The flow restrictor may be a cap that engages the outlet of the filter. Alternatively, it may be a lumen that tapers from a larger size to a smaller size, restricting the flow of gas.
Another embodiment of the assembly includes a filling mechanism to direct the gas into the first chamber. This embodiment also includes a valve mechanism that can move between a first position, prohibiting the flow of gas, and a second position, allowing the flow of gas from the first chamber.
Overall, this patent describes a hand-held gaseous injector assembly with various components and mechanisms to deliver therapeutic gas to a patient. The adjustable volume limiter, filter, and flow restrictor work together to control the flow and volume of gas, ensuring accurate and controlled delivery. The assembly may also include a filling mechanism and a valve mechanism for added functionality. The ability to remove and replace the filter enhances convenience and maintenance.
