MEDICAL CATHETER AND MEDICAL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240008916 titled 'MEDICAL CATHETER AND MEDICAL DEVICE
Simplified Explanation
The patent application describes a medical catheter and device that includes a catheter assembly with a needle channel, a needle assembly partially disposed in the needle channel, and a handle assembly with a grip and an advancement member. The advancement member is connected to the grip and can move relative to it to drive the needle assembly along the needle channel. There is also a first monitoring device that senses the arrival of the metal needle at a predefined position and generates a target signal.
- The catheter assembly has a needle channel with a predefined position.
- The needle assembly includes a metal needle that can move in the axial direction of the needle channel.
- The handle assembly has a grip and an advancement member that can move relative to the grip.
- The advancement member drives the needle assembly to move along the needle channel.
- The first monitoring device senses the arrival of the metal needle at the predefined position and generates a target signal.
- Monitoring of the movement distance of the advancement member relative to the grip starts when the metal needle reaches the predefined position.
- The movement distance accurately characterizes the length of the metal needle that has extended out of the catheter assembly.
Potential applications of this technology:
- Medical procedures requiring the use of catheters and needles, such as intravenous therapy, blood sampling, or drug delivery.
- Minimally invasive surgeries where precise control and monitoring of needle insertion and retraction are necessary.
Problems solved by this technology:
- Accurate monitoring of the length of the metal needle that has extended out of the catheter assembly.
- Improved control and precision in needle insertion and retraction during medical procedures.
- Enhanced therapeutic outcomes by ensuring the correct positioning and depth of needle insertion.
Benefits of this technology:
- Improved safety and efficiency in medical procedures involving catheters and needles.
- Reduced risk of complications or injuries due to accurate monitoring and control of needle insertion.
- Enhanced patient comfort and satisfaction through precise and controlled needle movements.
Original Abstract Submitted
a medical catheter and a medical device, including: a catheter assembly defining a needle channel comprising a distal section with a predefined position; a needle assembly () partially disposed in the needle channel and comprising a metal needle (), the needle assembly () movable in an axial direction of the needle channel so that the metal needle () passes by or reaches the predefined position; a handle assembly () comprising a grip () and an advancement member, the advancement member connected to the grip () and configured to be moveable relative to the grip (), the advancement member configured to drive the needle assembly () to move along the needle channel; and a first monitoring device configured to sense the arrival of the metal needle () at the predefined position and responsively generate a first target signal. during movement of the needle assembly () driven by the advancement member away from the grip (), monitoring on a movement distance of the advancement member relative to the grip () is commenced at the time when the metal needle () reaches the predefined position as monitored by the first monitoring device. the movement distance can accurately characterize a length of the metal needle () that has extended out of the catheter assembly, resulting in improved therapeutic outcomes.
