Problems solved by technology

Some prior art devices contain multiple complex parts that add significantly to manufacturing costs and interfere with the user's ability to feel when the needle is properly inserted into the patient
Other devices are unstable in positioning, require two-handed operation, or tend to retract the needle prematurely during shipping, storage, or handling

Embodiment Construction

[0031] refer to Figure 1-8 An embodiment of an IV catheter introducer 10 of the present invention includes a plunger assembly 12, a housing 14, a needle assembly 18, a retraction spring 80, a catheter hub assembly 16, and is disposed between the housing 14 and the catheter hub assembly 16. Conduit hub seal 58, and removable cover 76. Although a retractable needle is not required for use with the catheter hub seal 58 of the present invention, use of a retractable needle can reduce the chance of accidental needle stick injury once the housing 14 is separated from the catheter hub 16 and the needle 46 is withdrawn from the flexible sleeve 74. possibility. Plunger assembly 12, housing 14, body portions of retractable needle assembly 18, catheter hub assembly 16, and cover 76 may be made from a PDA-approved moldable polymer material, although it should be understood that the different portions may comprise different Material. The catheter hub seal 58 may be made of a polymeric ...

Abstract

A catheter introducer having a catheter hub seal that is engageable with the rear opening of the catheter hub to impede liquid flow out of the catheter hub following catheter insertion and subsequent withdrawal of the needle following separation of the housing from the catheter hub. The catheter hub seal is preferably made of a rubbery material and can be disposed between the housing and catheter assembly or can be attachable to the catheter assembly.

Description

technical field [0001] The present invention is a medical device for inserting a catheter into a patient, and more particularly relates to a catheter introducer for obtaining access to a blood vessel. One aspect of the invention relates to a catheter introducer having a catheter hub seal, which may be made of rubber material, which reduces leakage of bodily fluids such as blood out of the rear opening of the catheter hub after insertion of the catheter And reduce separation of the housing from the hub after the needle inserted therebetween is withdrawn. Another aspect of the present invention relates to an intravenous ("IV") catheter having an elastomeric hub seal that protects the patient from external contamination that would otherwise pass through after insertion of the catheter and removal of the needle used during insertion. The rear opening of the catheter hub enters the patient's blood vessel. The needle can be manually withdrawn using a biasing and retracting mechani...
