Body surface conduit fixing device – Type B

Body Surface Conduit Fixing Device – Type B

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Securement of Epidural and Central Venous Catheters

• Primary Use: Provides a sterile, single-use adhesive device with a specialized mechanical fixation clamp (or locking cradle) designed to securely anchor epidural catheters, central venous catheters (CVCs), and peripherally inserted central catheters (PICCs) to the patient’s skin without sutures .

• How it helps: For the anesthesiologist, interventional radiologist, and critical care nurse, the Type B device features a rigid or semi-rigid locking mechanism that securely grips the catheter hub or wings, preventing pistoning (back-and-forth movement) and accidental dislodgement . Unlike standard tape, the fixation clamp holds the catheter without compressing the lumen, maintaining flow integrity. For the patient receiving epidural analgesia, chemotherapy, or long-term antibiotics, this secure fixation eliminates the pain of suture removal and reduces the risk of catheter-related bloodstream infections (CRBSI) by preventing skin flora migration along the catheter tract.

2. Universal Compatibility with Multiple Conduit Types

• Primary Use: Engineered with an adjustable fixation cradle that accommodates a wide range of catheter diameters and connector sizes, including central lines, drainage catheters, arterial lines, and feeding tubes .

• How it helps: For the hospital supply chain manager and intensive care unit (ICU) clinician, the Type B device reduces inventory complexity by using a single fixation device across multiple catheter types. The adjustable cradle (often utilizing a “snap-on” or “click-lock” design) fits various manufacturers’ catheter wings without modification. For the patient, this means the nursing staff always has the correct securement device readily available, reducing delays in catheter dressing changes and minimizing the risk of accidental line pulls during patient turning or transport.

3. Skin-Friendly Adhesive Base with Hydrocolloid Protection

• Primary Use: Incorporates a soft, hypoallergenic adhesive pad (typically polyurethane film or non-woven fabric) that adheres to the percutaneously, providing a stable base for the fixation clamp while protecting the fragile skin of critically ill or irradiated patients .

• How it helps: For the wound care nurse and dermatology liaison, the Type B device features a gentle acrylic or silicone adhesive that minimizes the risk of Medical Adhesive-Related Skin Injury (MARSI). The integrated hydrocolloid or foam layer wicks moisture away from the insertion site, reducing maceration associated with sweat or serous drainage. For the patient with sensitive skin, history of radiation therapy, or long-term central access (e.g., oncology patients), this gentle but secure adhesion prevents painful skin tears and contact dermatitis, allowing for extended wear times (up to 7 days) without the need for painful re-taping.

4. Integrated Strain Relief for High-Flow and Large-Bore Catheters

• Primary Use: Features a reinforced strain relief channel that redirects tubing stress vectors away from the catheter insertion site, preventing kinking and pullout of large-bore hemodialysis or apheresis catheters .

• How it helps: For the dialysis nurse and apheresis specialist, the Type B device includes a built-in “J-loop” or “stress-relief” channel that absorbs the torque generated by heavy IV tubing. This prevents the catheter from being pulled out of the vessel during patient position changes. For the patient undergoing renal replacement therapy or stem cell collection, this strain relief prevents the sudden, painful sensation of the catheter tugging at the insertion site, allowing them to sleep or sit comfortably during long procedures (often 4-6 hours).

5. Visual Site Inspection Window for Infection Surveillance

• Primary Use: Manufactured with a transparent film or fenestrated window that allows clinicians to directly visualize the catheter insertion site for early signs of infection (erythema, drainage, swelling) without removing the securement device .

• How it helps: For the infection control practitioner and bedside nurse, the transparent backing provides continuous visibility of the “VAD” site. This facilitates compliance with the “Daily Review of Necessity” protocols and allows for instant assessment of site integrity during hourly rounding. For the patient, this transparency means the device does not need to be changed unnecessarily just to check the skin, reducing the frequency of dressing changes, which can be both painful and costly.

SECONDARY & SUPPORTIVE USES

1. Peripheral Nerve Catheter Stabilization: Used in regional anesthesia to secure catheters for continuous peripheral nerve blocks (femoral, sciatic, brachial plexus), preventing dislodgement that would interrupt post-operative pain control .

2. Chest Tube and Surgical Drain Management: Secures thoracostomy tubes and Jackson-Pratt (JP) drains to the chest or abdomen, preventing pullout that could lead to pneumothorax or surgical site infection .

3. Endotracheal Tube Fixation (Oral/Nasal): Modified Type B devices are used in anesthesia and critical care to anchor endotracheal tubes to the face, replacing traditional tape and reducing facial skin breakdown .

4. Nasogastric and Orogastric Tube Securement: Used to affix feeding tubes to the nose or cheek, preventing accidental removal which requires radiographic confirmation for re-placement .

5. Tracheostomy Tube Holder: Functions as a securement device for tracheostomy flanges, preventing tube dislodgement and reducing the risk of tracheal injury .

6. Hemodialysis Catheter Anchor: Specifically designed for large-bore dialysis catheters to withstand the high flow rates and patient movement during treatment, preventing venous stenosis caused by mechanical irritation .

7. Cardiovascular Monitoring Line Fixation: Used to hold arterial lines (A-lines) and pulmonary artery catheters in place in the ICU to ensure continuous hemodynamic monitoring accuracy .

8. Urinary Catheter Stabilization: Secures Foley catheters to the patient’s leg, preventing urethral traction and reducing the risk of catheter-associated urinary tract infections (CAUTI) .

9. Wound Drainage Tube Management: Attaches to surgical drains (e.g., Hemovac, Blakes) exiting the wound to prevent tugging and tension on the fresh incision line .

10. Interventional Radiology Access Site Care: Used to fix sheaths and dilators during interventional procedures to maintain vascular access without manual holding .

11. Pediatric Catheter Securement: Provides a secure, low-profile anchor for pediatric patients with small vasculature and highly mobile skin, reducing the risk of extravasation from dislodged IVs .

12. Patient-Controlled Analgesia (PCA) Line Protection: Holds PCA tubing securely in place so that the patient does not dislodge the line during sleep or ambulation .

13. Cerebral Spinal Fluid (CSF) Drainage System Securement: For patients with external ventricular drains (EVDs) or lumbar drains, the Type B device ensures the critical zero-level reference point remains stable to prevent over-drainage .

14. No-Sting Removal Protocols: Designed to be used in conjunction with silicone-based adhesive removers to facilitate pain-free device changes for burn or graft patients .

15. Home Healthcare Long-Term Line Management: Used by visiting nurses for patients with Port-a-Caths or PICC lines receiving home infusions, ensuring secure access without requiring professional suture removal .

16. Pre-hospital and Emergency Room Securement: Quickly applied in trauma bays to stabilize emergency lines (chest tubes, central lines) before the patient is transported to radiology or the ICU .

17. Magnetic Resonance Imaging (MRI) Compatibility: Type B devices are typically manufactured without metal components, making them safe to wear during MRI scans .
