AI Technical Summary

Problems solved by technology

However, these solutions do not fully meet the needs
Vial adapters require significant additional time to install or exchange vials for blunt cannula access
In addition, pre-piercing the septum during assembly is often difficult to confirm visually
Piercing the septum with a sharp needle and syringe prior to insertion of a blunt cannula has the double disadvantage of using a sharp needle, which is exactly what the use of a blunt cannula is intended to avoid, while being used for accessing vials or injection ports Additional fee for sharp needle and blunt cannula two needle system

Embodiment Construction

[0035] As shown in the exemplary drawings for purposes of illustration, there is shown an embodiment of a blunt cannula and insertion needle assembly, generally designated by reference numeral 10, made in accordance with the principles of the present invention, which assembly can be inserted into the blunt cannula Tubing 20 simply and quickly pierces a septum typically used on a medicament bottle or IV port (not shown) prior to obtaining or infusing fluids.

[0036] More specifically, as shown in Figures 1 and 2, assembly 10 is designed to completely contain a sterile syringe 18 and blunt cannula 20, and to retain insertion needle 15 from contamination and accidental sticking. Syringe 18 includes a hollow cylinder 57 and a plunger 38 . The plunger 38 includes a plunger head 58 and a plunger rod 40 attached to the head 58 . The plunger head 58 is slidably disposed within the barrel 57 and is in sealing contact with the inner surface of the barrel 57 . The rod 40 protrudes fro...

Abstract

The present invention relates to an access device which is provided as part of the packaging of a blunt tip cannula or blunt tip cannula / syringe combination. The access device is preferably positioned within an elongate sheath which also protects the blunt tip cannula and which also includes an internal barrier which separates the distal end of the blunt cannula from the distal end of the access device and protects one of the access pin or blunt tip cannula from exposure or contamination while the other is being used.

Description

technical field [0001] The present invention generally relates to an insertion device for use on a blunt cannula. In particular, the present invention relates to a system of components formed by a blunt cannula and insertion needle which greatly facilitates the user. Background technique [0002] Medical containers such as vials are commonly used to store large quantities of pharmaceuticals under sterile conditions prior to use. Most commonly, these medicament bottles allow access to the medicament inside through a septum made of a relatively thick, elastomeric material. The thick septum can be pierced with a sharp needle to gain access to the interior of the vial and can be resealed after the needle is withdrawn. The diaphragm is thick enough to maintain its integrity after multiple uses. [0003] Medical tubing, such as IV tubing, often has an injection portion to allow medication or other injectable fluids to enter the IV tubing. These injection parts usually include ...
