In the critical journey of recovery following surgery, the body’s natural healing processes are both remarkable and delicate. One of the most common challenges surgeons and care teams face is the management of wound exudate—the fluid that accumulates in surgical sites. Left uncontrolled, this fluid can lead to seromas, hematomas, increased risk of infection, delayed wound healing, and significant patient discomfort. Effective drainage is not merely a procedural step; it is a fundamental pillar of successful surgical outcomes. For decades, the quest has been for a drainage system that is simultaneously powerful in its function yet supremely gentle in its interaction with the patient’s body and seamless in its integration into clinical workflow.
Enter the next generation of drainage technology: the CIODC Disposable Medical Silicone Negative Pressure Drainage System. This system, encompassing 100ml and 200ml drainage bulbs and versatile suction devices, redefines post-operative care. Crafted from medical-grade silicone and designed for single-use with independent, sterile packaging, it represents a harmonious blend of biocompatible material science, intuitive design, and clinical efficacy. Let us explore how this system transforms a routine clinical task into a cornerstone of gentle, effective healing.
Part 1: The Clinical Imperative: Why Effective Drainage Matters

The primary goal of any surgical drain is to create a controlled pathway for fluid to exit the body, preventing its accumulation in spaces where it can cause harm. Traditional systems often present a compromise. Bulbs may be difficult to compress fully or maintain consistent suction. Tubes can be stiff or irritating. The CIODC system is engineered to resolve these friction points by addressing the core needs of both the clinician and the patient:
- For the Patient: Minimizing Discomfort and Anxiety: A drain that tugs painfully, has a hard, bulky bulb, or requires complex manipulation adds to post-operative stress. Our system prioritizes patient comfort through its soft, pliable materials and streamlined design.
- For the Clinician: Ensuring Reliability and Ease of Use: A drainage system must provide consistent, measurable negative pressure, be easy to activate and maintain, and integrate clearly into patient monitoring protocols. It should be a tool that works with the clinical team, not one that demands constant troubleshooting.
- For the Outcome: Mitigating Risk and Promoting Healing: By providing reliable, gentle suction, the system helps approximate wound edges, reduces dead space, and facilitates the removal of fluids that could become a medium for infection, directly supporting faster, cleaner healing.
Part 2: The Foundation of Safety and Comfort: Medical Silicone
At the heart of the CIODC system is its choice of material: high-purity, medical-grade silicone. This is far from an arbitrary selection; it is the critical determinant of the system’s performance and patient tolerance.
- Biocompatibility and Hypoallergenic Properties: Silicone is renowned for its excellent biocompatibility, meeting stringent international standards for prolonged tissue contact. It is non-toxic, non-irritating, and hypoallergenic, drastically reducing the risk of inflammatory reactions or contact dermatitis in sensitive post-operative skin.
- Optimal “Medium-Soft” Hardness: The system is engineered with a specific, medium-soft durometer. This precise hardness offers the perfect balance: it is soft and flexible enough to conform comfortably to the patient’s body, minimizing pressure points and discomfort, yet firm and resilient enough to maintain its structural integrity. The bulb can be compressed and will rebound effectively to create suction, and the tubing resists kinking while remaining gentle on internal tissues and exit sites.
- Durability and Clarity: Medical silicone is inherently strong and resistant to tearing. The translucent, pure white color of the components allows for clear visual assessment of the fluid’s color, consistency, and volume—a crucial factor in monitoring for complications like bleeding or infection.
Part 3: Intelligent System Design for Precision Drainage
The CIODC system is not a single product but a versatile suite designed to meet diverse surgical and post-operative needs. Its intelligence lies in its adaptable components.
1. The Drainage Bulb: Consistent, Controllable Suction
Available in 100ml and 200ml capacities, the silicone bulb is the system’s engine.
- Easy Activation: Simply compressing the bulb before connecting it or closing its valve creates immediate negative pressure.
- Graduated Volume Markings: Clear, accurate markings on the bulb allow for precise measurement of output, an essential parameter for clinical decision-making regarding drain removal.
- Secure, Leak-Free Valve: The integrated valve system is designed for one-handed operation, maintaining a reliable seal to preserve suction and prevent accidental spillage of biohazardous fluid.
2. The Drainage Tube & Device: Tailored for the Procedure
The system offers two sophisticated designs for the suction device, connecting the bulb to the surgical site:
- The Bellows-Type (“风琴式”) Suction Device: This design features a corrugated, accordion-like section.
- Function: It allows the clinician to manually create and regulate negative pressure by extending and compressing the bellows. This offers direct, tactile control over the suction force applied.
- Applications: Ideal for procedures requiring intermittent or carefully modulated suction, or where a specific level of vacuum needs to be established and maintained. Available in ~10cm and ~50cm tube lengths to accommodate different anatomical depths and surgical site locations.
- The Heat-Sealed (“热合式”) Suction Device: This design utilizes a sleek, uniform tube.
- Function: It is designed to connect to a pre-compressed drainage bulb. The negative pressure is generated by the bulb’s rebound, providing steady, continuous suction. The heat-sealed construction ensures a perfect, seamless, and robust connection between components, eliminating potential weak points.
- Applications: Excellent for general continuous drainage needs. Its streamlined profile is less likely to catch on bedding or clothing. The ~30cm tube length offers a versatile option for a wide range of procedures.
Part 4: The Non-Negotiable Protocol: Single-Use and Independent Sterility

In modern medicine, the principles of infection prevention are paramount. The CIODC system is unequivocally designed as a single-use, disposable medical device.
- Eliminating Cross-Contamination: Reuse is strictly prohibited and dangerous. Even with reprocessing, microscopic biofilms can form within the lumen of the tubing or the bulb, presenting an unacceptable risk of transmitting pathogens between patients.
- Guaranteed Performance and Safety: Each unit is manufactured, sterilized, and packaged to perform optimally for one patient, one procedure. The material properties and valve integrity are assured only for this single application.
- Independent, Ready-to-Use Packaging: Every component—whether a standalone bulb or a complete suction device—is provided in its own sterile, sealed package. This “independent packaging” ensures the product’s sterility is maintained until the moment of use in the operating room or at the bedside. It simplifies inventory, guarantees hygiene, and enhances procedural efficiency.
Part 5: A Guide to Selection: Matching the System to Clinical Need
Choosing the right configuration is straightforward and ensures optimal results:
- For general wound drainage with moderate exudate: A 100ml bulb with a Heat-Sealed Suction Device (30cm) is often an excellent, versatile starting point.
- For drainage sites with higher expected output (e.g., in some abdominal or orthopedic surgeries): The 200ml bulb reduces the frequency of emptying.
- For procedures requiring direct clinician control over suction pressure or for specific surgical applications: The Bellows-Type Suction Device (choosing 10cm for superficial sites or 50cm for deeper cavities) provides that hands-on precision.
