Method for Injecting a Liquid Substance and Apparatus

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention presents a novel needle-free injection method and device for delivering liquid substances, such as drugs or vaccines, into materials (especially biological tissue). It works by freezing a portion of the liquid to create a solid (ice) projectile, which is propelled into the target material using pressure. The projectile forms a channel into which the remaining liquid substance is then injected. The apparatus is designed for repeated use, reducing waste and avoiding needle-related issues.

Use CasesContent extracted from patent full text and abstract with AI.

• Intramuscular, subcutaneous, or intradermal injection of vaccines or medications in humans or animals without needles
• Mass immunization campaigns where waste reduction and device reusability are critical
• Drug administration for needle-phobic patients or in pediatric care
• Veterinary medicine for livestock or pets where rapid, low-waste injections are needed
• Injecting liquid substances into non-biological materials for industrial or research applications requiring localized delivery without contamination

BenefitsContent extracted from patent full text and abstract with AI.

• Eliminates the need for conventional needles, reducing needle-stick injury risks and patient anxiety
• Significantly reduces medical waste since the apparatus is reusable and doesn't rely on disposable parts
• Minimizes the risk of cross-contamination between patients because the device operates with no direct contact
• Allows precise control over the injection depth and volume, suitable for a wide range from nanoliters to milliliters
• Prevents back-splash and ensures localized delivery of the substance, leading to higher efficacy and cleaner administration
• Compatible with many drugs and vaccines, even those stable during freezing
• Potentially lowers costs associated with single-use injectors and medical waste management
