I. Raw Material Specification

The core raw material of rectal silicone catheters is 60 Shore A medical fumed silica silicone, a high-quality silicone material exclusively for medical applications that fully complies with manufacturing standards for medical consumables. It is engineered for direct contact with human anorectal tissue, with key raw material properties detailed below:

1. Safe & Compliant Material Composition：Medical fumed silicone is odorless, non-toxic and harmless, free of heavy metals, plasticizers and other hazardous substances. It delivers excellent biocompatibility, enabling direct contact with human mucous membranes without triggering allergies, irritation, inflammation or other adverse reactions. It meets safety criteria for implantable and skin-contact medical supplies, and is suitable for the delicate skin and mucosal environment of the human anorectal region.

2. Hardness Optimized for Clinical Use：Formulated at 60 Shore A hardness, the material strikes an ideal balance between softness and rigidity with uniform toughness. It retains the conformable softness of silicone to fit the physiological curves of the human rectum, eliminating friction injury and stinging pain caused by overly rigid tubing. Meanwhile, it offers robust structural support and deformation resistance: it resists collapse, kinking and distortion during use to maintain unobstructed fluid flow, meeting the operational demands of clinical procedures.

3. Superior Physical Properties：Medical fumed silicone features high purity, a dense, fine texture and smooth, non-porous surfaces that resist bacterial and dirt adhesion. It boasts outstanding temperature resistance, anti-aging performance and tear strength, tolerating standard medical disinfection and sterilization cycles without cracking, yellowing or degradation. Its stability and service life far exceed conventional silicone raw materials.

4. Certified Cleanroom Grade Purity：This dedicated medical-grade raw material undergoes purification treatment at the factory to achieve ultra-low impurity content, eliminating dust and particulate contamination at the source. It supports precision manufacturing in cleanroom environments, ensuring finished products meet baseline cleanliness standards for sterile medical consumables.

III. Manufacturing Process

Rectal silicone catheters are produced via one-piece compression molding. The entire workflow, including production, inspection and warehousing, is carried out in a dust-free cleanroom. Featuring precise craftsmanship and strict quality control, this process reliably guarantees product precision, sealing performance and sterile cleanliness. The core manufacturing procedures are specified as follows:

Raw Material Pretreatment

The 60 Shore A medical fumed silicone undergoes secondary screening, purification and rubber mixing to eliminate trace impurities within the raw material. This homogenizes the density and hardness of the silicone compound, ensures consistent performance across all batches, and prevents product defects stemming from raw material imperfections.

Precision One-Piece Compression Molding

Custom precision molds dedicated to medical-grade silicone are adopted. High-temperature compression molding forms the entire catheter structure in a single integrated step, with no splicing or bonding operations throughout production. The one-piece molding process completely eliminates hidden risks such as gaps, pinholes and detachment common in traditional spliced products. It delivers uniform tube walls, integral structures and superior sealing performance, while precisely controlling dimensional parameters including tube inner/outer diameter, length and curvature for exceptional product consistency.

Refined Post-Processing Treatment

Molded products go through edge trimming, polishing and flattening to remove burrs and sharp edges, ensuring smooth inner and outer catheter walls and eliminating risks of lacerating human rectal mucous membranes during intubation. Stress relief treatment is also implemented to boost the product’s flexibility and fatigue resistance, preventing deformation during long-term use.

100% Full Inspection in Cleanroom Environment

All products circulate within a standardized dust-free cleanroom at every stage to avoid contamination by ambient dust and bacteria. Finished products undergo 100% full inspection; each unit is individually tested for core indicators including dimensional accuracy, surface integrity, tube wall smoothness, flexibility and sealing performance to filter out defective and non-conforming products.

Sterilization Treatment & Warehousing

Products passing full inspection receive professional medical sterilization and dust-free packaging, then are stored in strict compliance with medical consumable warehousing standards under fully closed-loop management. This ensures all outgoing products are clean, sterile and qualified to meet stringent clinical medical requirements.

IV. Product Application Scenarios

Thanks to its safe soft texture, sterile cleanliness and excellent adaptability, the rectal silicone catheter is widely used in clinical departments of hospitals at all levels, rehabilitation institutions, home care and other settings. Its core applicable scenarios are listed below:

1. Clinical Anorectal Diagnosis & TreatmentSuitable for routine examinations and adjuvant therapies in the Department of Anorectal Medicine, Gastroenterology and General Surgery. It supports clinical procedures including rectal drug administration, enema irrigation, intestinal cleansing and effusion drainage. The soft catheter fits the physiological structure of the intestinal tract, effectively reducing patients’ discomfort during diagnosis and treatment and improving clinical safety.

2. Postoperative Rehabilitation CareFor patients recovering from anorectal or intestinal surgeries, the catheter can be used for postoperative intestinal cleansing, drug infusion and wound medication delivery. It prevents secondary damage to fragile postoperative wounds caused by rigid instruments, facilitates wound healing, and meets patients’ demands for repeated long-term postoperative care.

3. Home Care for Chronic DiseasesIdeal for home enema and intestinal care of patients suffering from constipation and chronic intestinal disorders. The non-irritating safe material enables easy operation and high patient tolerance for daily home rehabilitation care, greatly enhancing comfort and safety during household nursing.

4. Specialized Care for Pediatrics & GeriatricsConsidering the delicate intestinal tracts of children and fragile anorectal mucous membranes of elderly people, this 60-Shore-A moderate-hardness silicone catheter is mild and non-irritating. It is applicable to pediatric intestinal drug delivery and constipation relief care, as well as intestinal drainage and cleansing care for elderly patients, satisfying the medical nursing demands of special populations.

5. Rehabilitation PhysiotherapyUsed for adjuvant intestinal function rehabilitation care in rehabilitation departments. Gentle and safe catheter-assisted operations help improve intestinal peristalsis and unblock intestines, supporting physiotherapy for patients with intestinal dysfunction.
