Disposable Heparin Cap is a professional sterile medical infusion accessory specially designed for sealing and protecting the end of intravenous indwelling needles, central venous catheters and infusion pipelines. Manufactured from high-quality medical-grade transparent polypropylene (PP) shell and medical elastic sealing silicone pad, the product features a fully sealed barrier structure, puncture-resistant design and excellent biocompatibility. It adopts single-use sterile processing, which effectively avoids pipeline contamination, bacterial intrusion and cross-infection risks. Ergonomically optimized for standard Luer lock interface assembly, it is easy to install, tightly sealed and reusable for multiple punctures during the valid period, fully meeting the pipeline sealing and protection standards of hospitals, clinical wards, emergency departments and home infusion care, providing reliable safety guarantee for intravenous indwelling treatment.
The heparin cap adopts high-transparency medical PP material for the outer shell, which allows intuitive observation of internal pipeline status and residual liquid without visual obstruction. The built-in high-elastic medical silicone pad features excellent self-sealing performance, which can automatically close the puncture gap after repeated needle puncture, effectively preventing liquid leakage and external bacterial invasion. The standard universal Luer lock thread interface ensures tight and seamless locking connection with various indwelling needles and infusion catheters, avoiding loosening and falling off during use. The smooth outer shell structure prevents dust adhesion and bacterial growth, while the integrated fully enclosed design isolates external pollutants thoroughly. The product supports EO gas or gamma ray sterilization, complies with international and domestic medical device standards, and is suitable for clinical venous indwelling pipeline sealing and auxiliary protection in various medical scenarios.

Product Properties
1. Sterile and Safe, Anti-contamination: Adopts professional medical sterilization technology with sterility assurance level up to 10⁻⁶ and qualified EO residual content. Single-use design completely eliminates cross-infection and secondary pollution risks. Medical-grade raw materials are non-toxic, odorless and non-irritating to human blood vessels and tissues, ensuring safe and hygienic venous indwelling treatment.
2. Excellent Self-sealing & Leak-proof Performance: The high-elastic silicone pad has strong resilience and stable self-sealing ability. It can automatically and tightly close the puncture gap after multiple injections and punctures, effectively preventing infusion liquid leakage, blood backflow and pipeline blockage, maintaining stable pipeline sealing effect.
3. Standard Interface & Firm Connection: Adopts international standard Luer lock thread design, which can be tightly locked and assembled with all mainstream indwelling needles and venous catheters. It is not easy to loosen or fall off during patient movement and nursing operation, ensuring continuous and effective pipeline protection.
4. Visible Observation & Easy Nursing: The high-transparency shell allows real-time observation of internal pipeline liquid status and abnormal conditions, facilitating medical staff to judge pipeline patency and carry out standardized nursing operations, reducing hidden dangers of infusion complications.
5. Anti-bacterial Barrier & Pipeline Protection: The fully enclosed integrated structure effectively isolates external dust, bacteria and pollutants, avoiding bacterial colonization and pipeline infection caused by long-term indwelling of venous catheters, greatly reducing the incidence of infusion-related infections.
6. Cost-effective & Space-saving: Disposable use eliminates repeated cleaning and disinfection costs, reducing the operational burden of medical institutions. The compact and stackable structure saves storage and transportation space, with stable structure and no deformation during stacking, suitable for large-scale clinical application.
Application
1. Hospital Clinical Wards: Used for end sealing and sterile protection of peripheral venous indwelling needles and central venous catheters in internal medicine, surgery, pediatrics and oncology departments, suitable for intermittent infusion and long-term venous indwelling nursing.
2. Emergency & Intensive Care Departments: Applied for rapid pipeline sealing of emergency venous indwelling access and critically ill patients' central venous pipelines, ensuring pipeline patency and sterile safety during intermittent treatment intervals.
3. Home Health Care & Chronic Disease Infusion: Suitable for long-term home venous indwelling infusion treatment of chronic disease patients and postoperative rehabilitation patients, providing safe pipeline sealing protection and reducing the risk of household infusion infection.
4. Community Clinics & Grassroots Medical Institutions: Meet the daily venous indwelling needle sealing and infusion auxiliary nursing needs of grassroots medical institutions. With low cost and high safety, it is suitable for widespread daily medical nursing use.
5. Specialized Infusion & Rehabilitation Departments: Used for standardized pipeline protection in long-term chemotherapy infusion, parenteral nutrition infusion and rehabilitation nursing, ensuring long-term sterile and safe operation of venous access.

QA&QC

The Disposable Heparin Cap strictly complies with ISO 13485, CE and NMPA medical device quality management standards. Each production batch undergoes comprehensive and rigorous quality inspection, including material safety detection (BPA-free verification, medical biocompatibility evaluation, non-toxic and non-irritating test), interface assembly firmness calibration, silicone pad self-sealing performance test, pressure leakage resistance test and appearance full inspection. For sterile products, strict sterility validation is implemented, with EO residual content ≤10 μg/g and sterility assurance level reaching 10⁻⁶. All products are verified to be compatible with standard Luer lock infusion accessories and indwelling needles to ensure stable assembly and reliable sealing performance. Each batch is assigned an independent traceable batch number to realize full-process quality supervision from production to sales. Each package is equipped with a complete Instruction for Use (IFU), specifying standard assembly methods, nursing specifications and safety operation precautions.
Packing, Storage, Handling and Transportation
1. Packing: Sterile single heparin caps are individually sealed and packaged in medical paper-plastic composite bags or blister packs to ensure independent sterility. Batch products are packed in sturdy corrugated cartons with anti-collision and pressure-resistant protection. All packaging is clearly labeled with product name, specification, batch number, production date, expiration date and certification information.
2. Storage: Store in a clean, dry, dust-free and well-ventilated environment with temperature controlled at 2℃~30℃ and relative humidity ≤70%. Keep away from direct sunlight, high-temperature heat sources, sharp hard objects and corrosive chemical substances. Keep the original packaging sealed before use to avoid secondary pollution and performance attenuation.
3. Handling: For single-patient single use only, reuse and cross-use are strictly prohibited to prevent cross-infection. Before use, check whether the packaging is intact, free from damage, moisture and expiration. Discard the product immediately if the sterility is compromised or the sealing pad is damaged. Complete assembly and pipeline sealing operation in accordance with standard medical procedures, and dispose of waste products in accordance with medical waste management regulations.
4. Transportation: Transport in accordance with national and international medical device transportation specifications. Avoid violent collision, extrusion, moisture and long-term direct sunlight. The transportation environment temperature is controlled within 2℃~30℃ to ensure product packaging integrity, sterility and structural stability.
