Mui Scientific Anorectal Balloon Catheters: SR1B vs SR2B Comprehensive Comparison

When selecting the right anorectal expulsion catheter for your medical practice, understanding the key differences between Mui Scientific's SR1B and SR2B models is crucial for optimal patient outcomes. Both single-use PVC manometric catheters are designed for evaluating muscular contractions of the rectum, but they serve different clinical needs.

Product Overview Comparison

Key Differences: Inflation Medium

SR1B: Air-Only Inflation

The SR1B anorectal balloon catheter is specifically designed for air inflation only. This model includes a critical safety warning: "risk of balloon detachment or rupture if balloon filled with water". The air-only design makes it ideal for:

• Standard balloon expulsion tests

• Biofeedback training with handheld devices

• Practices prioritizing balloon safety and integrity

• Procedures where water inflation is contraindicated

SR2B: Dual Inflation Capability

The SR2B manometric catheter offers enhanced versatility with both air and water inflation options. This dual capability provides:

• Greater procedural flexibility

• Accommodation for different clinical protocols

• Options for both air-sensitive and water-sensitive patients

• Compliance with varying institutional preferences

Clinical Applications & Indications

Both anorectal expulsion catheters share identical clinical indications and applications:

Balloon Expulsion Function

1. Water-based lubricant application for insertion assistance

2. Catheter insertion through anus to 8-10cm depth

3. 3-way stopcock attachment for controlled inflation

4. Patient expulsion attempt within 2-5 minutes for normal function assessment

5. Immediate disposal post-procedure to prevent reuse

Biofeedback Applications

Both models excel in biofeedback training with handheld devices, enabling real-time pressure monitoring and patient education. The squeeze pressure measurements display directly on connected handheld devices, facilitating effective pelvic floor rehabilitation.

Storage & Handling Requirements

Both single-use manometric catheters maintain identical storage specifications:

• Temperature range: 15°C - 30°C (60.8°F – 80.6°F)

• Humidity limits: 10% - 75%

• Storage environment: Dry and clean location

• Manufacturer warranty: 6 months from purchase date

Safety Considerations & Contraindications

Universal Contraindications

Both models share the same contraindications:

• Rectal stenosis or structural deformities

• Active rectal disease increasing perforation risk

• Conditions causing unacceptable distention risks

Model-Specific Safety Notes

• SR1B: Never use water inflation - risk of balloon detachment

• SR2B: Safe for both air and water inflation

• Both require proper aseptic technique and universal barrier precautions

Target Patient Population

Both anorectal balloon catheters serve broad patient populations without specific demographic restrictions. Usage decisions remain at the discretion of medical personnel with professional training in gastrointestinal manometry.

Choosing the Right Model for Your Practice

Select SR1B When:

• Your protocol exclusively uses air inflation

• Maximum balloon safety is paramount

• Budget considerations favor single-inflation capability

• Staff training focuses on air-only procedures

Select SR2B When:

• Procedural flexibility is essential

• Multiple inflation methods are required

• Patient populations have varying sensitivities

• Institutional protocols mandate water inflation options
