Description

Mechanical transmission device having a multi-position rotating element Inserting a needle into a patient's vascular structure tends to cause anxiety for both the patient and the medical staff for various reasons. Blood collection typically begins with needle insertion. Attempts have been made to use peripheral venous catheters (PIVCs) to collect blood from a patient's vascular structure, which can reduce the number of needle insertions experienced by the patient. A common type of IV catheter is the over-the-needle PIVC. As the name implies, the over-the-needle PIVC can be mounted on an inducer needle having a sharp distal tip. The sharp distal tip can be used to puncture the patient's skin and vascular structures. Insertion of the PIVC into the vascular structure can be performed after puncturing the vascular structure with the needle. The needle and PIVC are typically inserted into the vascular structure through the patient's skin at a small angle, with the bevel of the needle facing away from the patient's skin. Once the placement of the needle within the vascular structure is confirmed, medical personnel can temporarily block the flow within the vascular structure and retract the needle, leaving the PIVC in place for subsequent blood collection and/or fluid infusion. There are several limitations to current PIVC blood collection approaches. The use of current PIVCs to draw blood is slow and somewhat inefficient, particularly when the patient has different endovenous access routes or veins that are difficult for medical personnel to access. Additionally, blood samples obtained via PIVCs may often have to be discarded due to concerns regarding sample quality. Furthermore, the use of current PIVCs to draw blood can result in catheter kinking. Moreover, PIVCs can be narrow, crushed, or clogged over time, leading to PIVC failure.
