About B. Braun Company

Product Introduction

B. Braun arterial and venous indwelling needleThe Braun Intrinsic Safety IV Catheter is a high bypass peripheral venous access device developed and produced by the German Braun Medical Group, specifically designed for clinical infusion therapy, drug infusion, and blood collection. This product adopts fully automatic passive safety protection technology, combined with a dual blood return confirmation system, to provide medical staff with a safe and accurate venipuncture solution, while maximizing patient comfort. The product complies with the ISO 10555-1/5 international standard and does not contain DEHP, latex, or PVC components. It is suitable for various patient groups such as adults, children, and newborns.

Core functions and clinical roles

B. Braun arterial and venous indwelling needleIt is a core device in the field of modern intravenous therapy, and its main clinical functions are reflected in the following aspects:

Establishing reliable venous access: As a key tool for peripheral intravenous infusion, this product can establish a stable and long-term liquid infusion channel in the patient's peripheral vein. Compared to traditional steel needles, indwelling needles can be retained in blood vessels for 72-96 hours or even longer, significantly reducing the pain caused to patients by repeated punctures, while also reducing the risk of vascular damage and infection caused by multiple punctures.

Multi scenario treatment support: suitable for various clinical scenarios such as continuous infusion therapy, intermittent drug injection, intravenous nutrition support, blood transfusion therapy, blood sample collection, and hemodynamic monitoring. Especially for patients who require long-term intravenous treatment, such as chemotherapy, antibiotic therapy, or critically ill patients, the use of indwelling needles significantly improves treatment compliance and nursing efficiency.

Ultrasound guided deep vein access: The Braun deep vein indwelling needle series is designed for patients with difficult vascular access, and can enter deeper veins under ultrasound guidance. It is suitable for obese patients, patients with poor vascular conditions, or patients with superficial vein damage, effectively avoiding invasive procedures such as central venous catheterization (CVC) or peripheral central venous catheterization (PICC).

Product design and technological advantages

The Braun arteriovenous catheter integrates multiple innovative technologies in its structural design to ensure the success rate of puncture and ease of operation

Universal back cut needle tip design: using a unique seven blade polishing process (ordinary needles have four blades), the needle tip is precisely ground to form a triangular incision, combined with a back cut inclined surface design, allowing for multi angle puncture at 15-45 degrees, which can achieve precise puncture of superficial veins and meet the needle insertion needs of deep blood vessels. This design significantly reduces puncture trauma, lowers the risk of vascular wall damage, and improves the success rate of the first CI puncture.

Double blood return confirmation technology: The innovative Double Flashback technology provides two independent blood return observation windows. The first CI needle core confirms that the needle tip has entered the vascular lumen, and the second catheter confirms that the catheter has been fully inserted into the blood vessel. This dual confirmation mechanism effectively avoids puncture failure caused by incomplete catheterization due to only the needle core returning blood, significantly improving the success rate of a single puncture.

Ergonomic wing design: The product is available in two models: Winged and Non winged. The winged design is equipped with a wide and stable butterfly wing, which is convenient for medical staff to hold, fix and operate the needle, especially suitable for situations that require precise control of the puncture angle; The wingless design reduces tissue stimulation and is suitable for patients with higher comfort requirements.

Transparent observation window and detachable exhaust plug: The catheter base is equipped with a transparent observation section for easy visual confirmation of blood return; The detachable ventilation plug design allows for the connection of a syringe for blood collection or pressure monitoring, enhancing the product's versatility.

Material characteristics and biocompatibility

The material selection of the Braun arteriovenous catheter reflects the extreme pursuit of patient safety and comfort:

Polyurethane (PUR) catheter material: Made of high-quality polyurethane material, it has excellent biocompatibility and blood compatibility. After entering the blood vessels, this material will automatically soften by about 50%, floating and adhering to the vessel wall, significantly reducing mechanical stimulation to the vascular endothelium and lowering the incidence of phlebitis. At the same time, the softened catheter can increase the flow rate by up to 50%, and the 24G specification catheter can achieve the flow rate of the traditional 22G catheter, achieving the effect of 'small needle, large flow'.

Alternative to Fluorinated Ethylene Propylene (FEP): For clinical scenarios that require stiffer catheters (such as arterial catheterization), FEP material options are provided to ensure the stability of the catheter during high-pressure injection or arterial monitoring.

Stainless steel chromium nickel steel needle core: The guide needle is made of medical grade stainless steel material imported from Germany, which has undergone special heat treatment process and has high hardness and excellent toughness, ensuring the sharpness of puncture while avoiding the risk of needle breakage. The needle hub is made of ABS engineering plastic, and the protective sheath and catheter hub are made of PP material. The overall structure is sturdy and durable.

Environmentally friendly additive free design: The entire range of products does not contain phthalates (DEHP), natural rubber latex, or polyvinyl chloride (PVC), eliminating the release of potential allergens and harmful substances. It is particularly suitable for sensitive patients and newborns, and meets modern medical environmental protection requirements.

Security protection mechanism

The safety performance of the Braun arteriovenous catheter is its core competitive advantage, and it adopts a fully automatic passive safety protection system:

Fully automatic passive safety shield: The safety device is automatically activated when the needle core is fully withdrawn from the catheter, without the need for medical personnel to manually operate or press any buttons. The protective shield instantly covers the needle tip and locks it in place, forming a physical barrier that effectively prevents needlestick injuries after use. This mechanism cannot be bypassed or invalidated, completely eliminating occupational exposure risks caused by human negligence or hasty operation.

Anti re insertion design: The activated safety shield mechanically locks the needle tip to prevent it from being pushed back into the catheter, avoiding accidental punctures or product misuse, providing extreme protection for medical staff.

Multi pathway blood control technology (Safety 2 series): The high-end model is equipped with a multi-channel blood control connector, which can prevent blood reflux without compressing the blood vessels during the puncture process, significantly reducing the risk of blood exposure and contamination. The connector design allows for multiple needle free connections and automatically seals upon each insertion, reducing the risk of catheter-related bloodstream infections (CRBSI).

X-ray opaque marking: The catheter is equipped with X-ray imaging stripes, which facilitate the confirmation of the catheter position during imaging examinations and prevent catheter displacement or ectopic detection in a timely manner.

Applicable departments and clinical applications

The Braun arteriovenous catheter is widely used in multiple clinical departments of medical institutions at all levels

Emergency department and ICU: Rapid establishment of venous access is the key to rescuing critically ill patients. The rapid blood return confirmation and safety design of the Braun indwelling needle are particularly suitable for emergency catheterization in high-pressure environments. The deep vein series can meet the rescue needs of patients with difficult vascular access.

Oncology and Chemotherapy Centers: Patients who require long-term treatment with chemotherapy drugs often have poor vascular conditions. The soft PUR material of the Braun indwelling needle can reduce the stimulation of chemotherapy drugs on blood vessels, prolong the indwelling time, and reduce the pain of repeated punctures.

Operating Room and Anesthesiology Department: Reliable venous access is required for perioperative fluid management, anesthesia administration, and intraoperative monitoring. The product supports 300 PSI high-pressure injection (18-24G specification) to meet the rapid infusion needs of contrast agents.

Pediatrics and neonatology: latex free and DEHP free design ensures safe use for newborns; Fine specification selection (24G) suitable for small blood vessels in children, reducing puncture trauma.

General wards and outpatient clinics: Basic medical scenarios such as routine infusion therapy, antibiotic administration, and nutritional support, with Braun indwelling needles providing an economical and reliable solution.
