Import Csf Flow Control Valve Small (L.M.H) 04120 — Buy in Bulk from Supplier in Taiwan

The Csf Flow Control Valve Small (l.M.H) 04120 is a precision medical device designed for cerebrospinal fluid drainage in neurosurgical applications. It operates via dual pressure membranes that regulate flow based on patient posture, maintaining consistent intracranial pressure when the patient transitions from horizontal to vertical positions. The valve is calibrated for low flow rates, typically 1 to 4 ml per hour, and is compatible with standard peritoneal catheters used in hydrocephalus management.

The valve body is constructed from medical-grade polycarbonate with silicone sealing components, ensuring biocompatibility and resistance to long-term fluid exposure. The slit valve mechanism at the distal end responds to negative pressure changes during posture shifts, preventing siphoning without requiring external adjustments. This design aligns with standard ISO 10555-1 requirements for CSF shunt components, though no certification documents are provided by the supplier.

This valve is primarily purchased by neurosurgical hospitals, spinal implant distributors, and medical device importers serving Asia-Pacific markets. It is supplied in sterile, single-use packaging with no reusable components. Buyers should confirm compatibility with their catheter system and verify the flow rate tolerance range, as the supplier does not specify exact pressure thresholds. Packaging is in blister packs of 10 units, with bulk orders typically shipped in cartons of 100.

Wellong Instruments Co., Ltd. is a Taiwan-based manufacturer specializing in neurosurgical flow control devices. The company is registered with the Taiwan Food and Drug Administration and maintains a harbor-tier trust rating based on business verification status. The supplier does not publish clinical data, test reports, or client lists, and response metrics are not available on the listing.

The supplier focuses exclusively on passive mechanical valves for CSF drainage, with no indication of active pump systems or electronic components. Their product line appears limited to a small set of valve models, including the 04120 variant. There is no evidence of export history, ISO certification, or in-house testing facilities beyond what is implied by their product design.
