Import Bladder Valve — Buy in Bulk from Supplier in China

The bladder valve from Hangzhou Qiushi Medical Co., Ltd is a medical-grade device designed for urinary management, featuring a patented design (zl03204214.0) that enables one-way flow control with minimal leakage risk. It is constructed from medical-grade silicone and thermoplastic elastomers, with a diameter of 8mm and a length of 45mm, compatible with standard catheter systems. The valve operates without external power and requires no manual activation, relying on pressure differentials to open and close.

The materials used are tested for biocompatibility per ISO 10993-5 and are free from phthalates and latex. The internal sealing mechanism uses a self-closing diaphragm, a standard feature in clinical-grade intermittent catheterization valves. Typical industry tolerances for flow rate range between 15 to 25 mL per second under 20 cm H2O pressure, which this unit meets without external adjustment. Surface finish is smooth to reduce friction and biofilm accumulation during use.

This valve is used in home care, long-term care facilities, and hospitals for patients with neurogenic bladder or spinal cord injuries. Buyers include medical equipment distributors, rehabilitation centers, and home health agencies. Packaging is sterile, single-use, and sealed in polyethylene with desiccant. Minimum order quantities are negotiable, with standard lead times of 15 to 20 days for bulk orders. Shipping terms include FOB Shanghai and CIF destination ports, with payment via T/T or L/C.
