Abstract
Embodiments disclose a disposable protective assembly apparatus for a dental syringe body of a dental syringe. The apparatus is a combination of a disposable syringe tip and a disposable protective sleeve, the sleeve being pre-attached to the syringe tip, and the sleeve being in a pre-folded position to be quickly and easily slid over the dental syringe prior to a dental operation.
Claims20
A disposable integral assembly apparatus for a dental syringe body of a dental syringe, said apparatus comprising:
- a) a syringe tip configured to connect to said dental syringe body of a dental syringe;
- and b) a sleeve, wherein said sleeve comprises an extruded portion proximal to an end of said syringe tip that connects to said dental syringe, wherein said extruded portion concomitantly connects an outer surface of said syringe tip to said sleeve, and wherein said extruded portion:
- i) is not in a fixed position relative to said syringe tip and ii) is configured so as to avoid detachment of said syringe tip from said sleeve, wherein when an open end of said sleeve distal to said extruded portion slides over said dental syringe body, an air seal is formed preventing contaminants from transferring to or from said dental syringe body through an end of said sleeve proximal to said extruded portion, and wherein said sleeve is adapted to engage with said body of the dental syringe and wherein said sleeve includes adhesive tape(s), slide channel, drawstring(s), buckle sets or combinations thereof.
A dental syringe system, the system comprising:
- a) a dental syringe body;
- b) a syringe tip configured to connect to said dental syringe body of a dental syringe;
- and c) a sleeve, wherein said sleeve comprises an extruded portion proximal to an end of said syringe tip that connects to said dental syringe, wherein said extruded portion concomitantly connects an outer surface of said syringe tip to said sleeve, and wherein said extruded portion:
- i) is not in a fixed position relative to said syringe tip and ii) is configured so as to avoid detachment of said syringe tip from said sleeve, wherein when an open end of said sleeve distal to said extruded portion slides over a dental syringe body, an air seal is formed preventing contaminants from transferring to or from said dental syringe body through an end of said sleeve proximal to said extruded portion, wherein said extruded portion forms a non-zero angle between said sleeve proximal to a distal end of said syringe tip and the end of the sleeve proximal to a retainer assembly of the dental syringe body when attached thereto, which formed non-zero angle delimits said air seal, wherein said sleeve is configured to slide onto said dental syringe body to cover said dental syringe body during operation and slide off of said dental syringe body after said operation, and wherein said sleeve is adapted to engage with said body of the dental syringe and wherein said sleeve includes adhesive tape(s), slide channel, drawstring(s), buckle sets or combinations thereof.

A method of protecting a dental syringe body, the method comprising:
- a) seating a syringe tip of a disposable integral assembly apparatus in a retainer assembly of said dental syringe body of a dental syringe, wherein said apparatus comprises:
- i) a syringe tip configured to connect to said dental syringe body of said dental syringe;
- and ii) a sleeve, wherein said sleeve comprises an extruded portion proximal to an end of said syringe tip that connects to said dental syringe, wherein said extruded portion concomitantly connects an outer surface of said syringe tip to said sleeve, wherein said extruded portion is not in a fixed position relative to said syringe tip and is configured so as to avoid detachment of said syringe tip from said sleeve, and wherein when an open end of said sleeve distal to said extruded portion slides over a dental syringe body, an air seal is formed preventing contaminants from transferring to or from said dental syringe body through an end of said sleeve proximal to said extruded portion;
- and b) sliding said sleeve down said dental syringe body, wherein said sleeve covers the dental syringe body during operation and slides off of the dental syringe body after said operation, and wherein said sleeve engages with said body of the dental syringe via adhesive tape(s), slide channel, drawstring(s), buckle sets or combinations thereof.
