Abstract
The device for the administration for the delivery internal or sub-dermal therapeutic fluids to a human body comprising at least an ink-jet printing type head for the delivery of a pattern of liquid droplets in combination with a fluid supply system and means for controlling the supply and operation of the head. The jet pattern can be controlled in the x-y axes. Means for controlling the target along a "z" axis are provided in the form of a spacer and the focus of fluid may be controlled via an electromagnetic field system. Preferably, at least two heads are arranged so that the jets are emitted in a converging spray pattern directed to the same location, which is convenient for delivering binary components of a therapeutic compound which is unstable.
Description
PRECISION JET ADMINISTRATION OF THERAPEUTIC FLUIDS.
This invention relates to apparatus for the internal or subdermal administration of fluids such as therapeutic fluids, which may include inert fluid carriers with s colloidal active ingredients, non-active ingredients with a view to physical disruption. One object Is to allow local administration of therapeutic fluids generally, at a higher concentration than could safely be achieved by systemic administration.
0 According to the invention apparatus for the administration of therapeutic fluids to the human body comprises at least one jet printing head for the delivery of a pattern of liquid droplets, a supply system for the supply of fluid to the printing head, and means for controlling the supply and the operation of the head in accordance with a desired dosage of the fluid.
A practical embodiment of the invention Includes at least one printing head having a construction similar to that of an ink-Jet printing head. This is coupled to a supply of therapeutic fluid by way of an adjustable valve under the control of a controller which can be set to enable the head to deliver the fluid in accordance with a desired dose. The head may be placed close to the skin to administer the therapeutic fluid subdermally, for example for the treatment of superficial lesions (e g psoriasis). The head may be modified to allow the application of fluid to internal treatment sites 2s The jet pattern can be accurately controlled in the 'x-y' axes (i.e. a right angles to the direction of the jets). It may not be necessary to provide any control of the jets in the z-drection, especially if the penetrability of soft tissues does not vary significantly across a rage of subjects In the event of significant variability of penetration, some means of controlling the target would be desirable In some circumstances this means may be a physical spacer, but may comprise an electromagnetic field system which can control the focus of the fluid, which may mclude electrically charged or magnetic particles.
Ordinary inkjet printing heads have nozzles arranged so that the ink jets are s emitted in parallel streams. For the present invention the head preferably has nozzles disposed to provide a converging spray pattern.
The apparatus may comprise at least two heads for the delivery of different fluids to the same location. This represents a convenient delivery system for the binary (or n-ary) components of a therapeutic compound which is unstable. - 3
