Body surface conduit fixing device – Type I

Body Surface Conduit Fixing Device – Type I

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Rotating Nut and Slider Mechanical Locking System

• Primary Use: Provides a sterile, single-use catheter fixation device featuring a mechanical locking system composed of a rotating nut and slider mechanism , designed to securely fasten medical conduits without relying on adhesive contact with the catheter surface.

• How it helps: For the intensive care unit (ICU) nurse and vascular access specialist, the Type I device employs a positive-locking mechanical interface that engages around the catheter via a slider mechanism that is tightened using a rotating nut . This design allows clinicians to achieve secure fixation with precise tension control, accommodating various catheter diameters without requiring multiple device sizes. For the patient, this mechanical locking ensures the catheter remains firmly in place even during patient movement, coughing, or repositioning, significantly reducing the risk of accidental dislodgement without the need for suture placement.

2. Sponge Pad for Patient Comfort and Pressure Relief

• Primary Use: The Type I device incorporates a soft sponge pad/sponge cushion positioned between the locking mechanism and the patient’s skin , providing cushioning that prevents pressure ulcers and distributes device weight across a broader surface area.

• How it helps: For the wound care nurse and long-term catheter management team, the integrated sponge layer serves as a protective barrier that absorbs shear forces and relieves pressure from the catheter hub against the skin. This design is particularly valuable for patients requiring extended catheter dwell times, those with diminished sensation (such as diabetic neuropathy or spinal cord injury), or patients who are sedated and unable to reposition themselves. For the patient, the sponge cushioning prevents the development of pressure injuries at the catheter exit site—a common complication that can lead to pain, infection, and premature catheter removal.

3. Housing with Bite Block for Oral/Endotracheal Applications

• Primary Use: The Type I configuration includes a housing component incorporating a bite block (牙垫) and cheek fixation straps , specifically designed for oral placement to secure endotracheal tubes and prevent patients from biting down on the airway device.

• How it helps: For the anesthesiologist, respiratory therapist, and critical care nurse, the Type I device serves as an endotracheal tube fixation system that combines a bite block to prevent tube occlusion from patient biting, with adjustable cheek straps to secure the tube position . The bite block maintains an open oral airway, while the integrated tube channel holds the endotracheal tube at the correct depth . For the intubated patient, this dual-function design prevents the life-threatening complication of tube occlusion from biting, reduces the risk of accidental extubation, and minimizes trauma to the lips, teeth, and oral mucosa from traditional tape fixation methods.

4. Cheek Fixation Straps for Secure Positioning

• Primary Use: The Type I device is equipped with cheek fixation straps (面颊固定带) that wrap around the patient’s head or face , providing circumferential securement that distributes retention forces across a broader area rather than concentrating them at the catheter insertion site.

• How it helps: For the ICU nurse managing a patient with an endotracheal tube or other oral conduit, the cheek straps offer an alternative to traditional adhesive tape fixation, which can cause skin breakdown on the face with prolonged use. The adjustable straps allow for tension customization and can be repositioned without removing adhesive from the skin. For the patient, this strap-based securement reduces the risk of facial skin irritation and Medical Adhesive-Related Skin Injury (MARSI) commonly associated with prolonged taping of oral tubes.

5. Multiple Component Assembly for Comprehensive Securement

• Primary Use: The Type I device is assembled from multiple components including a rotating nut, slider mechanism, sponge pad, housing (shell) with integrated bite block, and cheek fixation straps , working together as a unified catheter securement system.

• How it helps: For the clinician, the multi-component design allows each element to serve a distinct function: the rotating nut and slider provide mechanical clamping force on the catheter, the sponge pad cushions the patient’s skin, the housing with bite block maintains oral airway patency, and the cheek straps provide external stability . This modular approach allows for device adjustment without complete removal. For the patient, the comprehensive securement minimizes the need for multiple separate devices (bite block + tube holder + skin protectant) and reduces the number of separate adhesive applications to the skin.

SECONDARY & SUPPORTIVE USES

1. Endotracheal Tube Fixation for Mechanically Ventilated Patients: Secures endotracheal tubes in patients requiring mechanical ventilation, with the bite block preventing tube occlusion from patient biting and the straps securing tube position .

2. Tracheostomy Tube Stabilization: Some Type I configurations may be adapted for use with tracheostomy tubes, providing an external securement mechanism that reduces tube movement and prevents accidental decannulation.

3. Oropharyngeal Airway Securement: Used to hold oropharyngeal airways in place during anesthesia or sedation, preventing displacement that could compromise airway patency.

4. Nasogastric Tube Fixation (Oral Route): Secures nasogastric or orogastric feeding tubes in patients where nasal placement is contraindicated (e.g., facial trauma, nasal surgery, coagulopathy), using the bite block to prevent tube damage from biting.

5. Oral Suction Catheter Securement: Holds oral suction catheters in position for patients requiring frequent oral suctioning, maintaining access while reducing manual holding requirements.

6. Dental Procedures Requiring Mouth Opening: Used during oral surgery or dental procedures to maintain mouth opening while protecting the endotracheal tube from damage.

7. Mouth Piece Holder for Pulmonary Function Testing: May be adapted to hold mouth pieces for pulmonary function testing or sleep study equipment.

8. Intraoperative Anesthesia Airway Management: Used in operating rooms during general anesthesia to secure endotracheal tubes during surgical procedures.

9. Emergency Department Airway Securement: Quickly applied in emergency situations to stabilize endotracheal tubes before patient transport to the ICU or radiology.

10. Post-Anesthesia Care Unit (PACU) Airway Management: Secures endotracheal tubes for patients emerging from anesthesia, where coughing or agitation increases the risk of accidental extubation.

11. Burn Patient Airway Securement: Used for intubated burn patients where facial skin trauma precludes traditional tape fixation; the strap-based securement avoids adhesive application to damaged skin.

12. Trauma Patient Airway Management: Applied in trauma bays for intubated patients with facial injuries where tape adhesion is compromised by blood, moisture, or wounds.

13. Prone Positioning Airway Securement: Used during prone positioning procedures (e.g., spinal surgery, ARDS management), where gravity and positioning increase the risk of tube dislodgement.

14. Transport Airway Stabilization: Secures endotracheal tubes during intra-hospital or inter-facility patient transport, where movement and vibration can cause tube migration.

15. MRI-Compatible Airway Securement: The Type I device may contain minimal metal components; verify individual product specifications for MRI compatibility.

16. Extended ICU Stay Airway Management: Used for patients requiring prolonged intubation where facial skin integrity preservation is a priority and traditional tape causes breakdown.

17. Pediatric Airway Securement: Smaller-sized Type I devices may be available for pediatric patients, where secure tube fixation is critical but adhesive tape may cause skin damage.

18. Facial Burns and Skin Graft Protection: Particularly useful for patients with facial burns or recent facial skin grafts where adhesive tape is contraindicated.

19. Head and Neck Surgery Recovery: Secures airway devices in post-operative head and neck surgery patients where anatomy may be altered or dressings cover the face.

20. Neurologically Impaired Patient Airway Management: Used for patients with altered mental status, agitation, or seizure disorders who are at increased risk of self-extubation.

21. Long-Term Acute Care (LTAC) Airway Management: Provides durable, extended-wear securement for patients requiring prolonged mechanical ventilation in long-term acute care facilities.

22. Home Mechanical Ventilation: May be used by home healthcare providers for ventilator-dependent patients at home, where family caregivers can manage the device without specialized adhesive removal techniques.

23. Palliative Care Airway Management: For terminally ill patients requiring intubation, the strap-based system reduces the burden of frequent tape changes.

24. Interfacility Transport Airway Stabilization: Used by transport teams (air or ground) to ensure endotracheal tube security during patient transfers between facilities.

25. Operating Room Post-Extubation Airway Protection: May be used to secure oral airways during the immediate post-extubation period to maintain airway patency.
