Description

Region selection indicating device of venous indwelling needle under ultrasonic guidance

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to regional selection indicating device of needle is kept somewhere to vein under ultrasonic guidance.

Background

The venous indwelling needle is also called as venous trocar. The core components include a flexible catheter/cannula that can be indwelling in a blood vessel, and a stainless steel puncture guiding stylet. When in use, the catheter and the needle core are punctured into a blood vessel together, after the catheter completely enters the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel so as to carry out infusion treatment.

When selecting the puncture site of the intravenous access of the indwelling needle, the following principles are generally followed:

1. arm preferences for central venous catheter site selection are discussed with the patient and suggested selection of a non-dominant arm.

2. The puncture should be done away with the medial aspect of the wrist to avoid pain and damage to the radial nerve. The position of the vascular access device for catheterization should avoid the limb joint; areas of pain upon palpation; damaged areas and sites distal to these damaged areas, such as areas with open wounds; areas of infection on the extremities; damaged blood vessels (e.g., bruised purple, oozing, phlebitis, hardened, stringy, or engorged blood vessels); the location of the venous valve; sites where extravasation or extravasation previously occurred and areas where surgery was planned.

3. Selecting a puncture part to avoid the tail end of the upper limb which receives the side mammary gland operation to clean the axillary lymph nodes and has lymphedema or arteriovenous fistula/transplantation; after radiation treatment of the side of the body; or affected limbs after cerebrovascular accident. Unnecessary venipuncture of the peripheral vein of the distal end of the upper limb intended for future vascular access is avoided for patients with chronic kidney disease. A collaborative discussion about the benefits and risks of using affected limb veins should be conducted with the patient and with a qualified independent practitioner (LIP).

4. The placement of hemodialysis fistulas, vascular prostheses, and catheters for infusion therapy requires instruction from a nephrologist or qualified independent practitioner, except in an emergency.

5. Peripheral venous indwelling needle placement is performed using Ultrasonography (US) on adult and pediatric patients who have difficulty finding venous access and/or failed venipuncture attempts.

The problems existing at present are as follows:

when the ultrasonic examination method is used for placement, after the ultrasonic guidance is used for obtaining the optimal arm blood vessel retention position, the back area of the hand is not finely divided, so that medical staff who perform puncture operation cannot know the optimal puncture arm position more clearly and directly, and the retention failure rate of the retention needle is increased.
