AI Technical Summary

Problems solved by technology

[0006] However, with conventional infusion sets there is a problem that the introducer needle and catheter can move relative to each other before and during insertion of the catheter
[0007] However, due to relative motion between the introducer needle and catheter, proper placement distance is sometimes not maintained
If not placed at an appropriate distance, puncture resistance will increase and may cause significant pain to the patient

Abstract

The present disclosure relates to a needle hub (10) comprising a core mounting structure (27), a first panel (28) and a second panel (29) connected to the core mounting structure (27). An opening is formed between the first panel (28) and the second panel (29); an introducer needle (72) is fixedly attached to the core mounting structure (27) for insertion into a patient;and actuating rods (16, 18)that are longitudinally cantilevers from the core mounting structure (27) at their central portion and have actuation buttons (12, 14) disposed at the free proximal end and are set free The paw at the far end (24, 26). The present disclosure also relates to an insertion device including the needle seat.

Description

technical field [0001] The present invention relates generally to needle hubs and, more particularly, to introducer hubs for use with infusion sets such as hypodermic infusion sets used with infusion pumps in the infusion of insulin and other medications. Background technique [0002] One mode of insulin infusion therapy for diabetes involves infusion pump therapy via a catheter, needle, or other type of cannula. Infusion pumps offer the advantages of continuous infusion of insulin, precise dosing, and programmable dosing schedules. Together these advantages lead to more accurate blood sugar control. In this mode of insulin infusion therapy, the infusion pump remains attached to the user and the desired dose of insulin is delivered to the user through the infusion pump. [0003] One type of cannula is a catheter, which is usually a tube that can be inserted into the body to enable administration of fluids. In infusion pump therapy, catheters can vary in type and size, but...
