The "Without Logo Printing" option suggests a base price for standard units, while custom branding adds to the cost.

Minimum Order Quantity (MOQ) is another critical cost determinant. The observed MOQ range is 1 to 300 units. Purchasing at the lower end of this spectrum (MOQ 1) may result in a higher unit price due to the lack of economies of scale. Conversely, ordering at the higher end (up to 300 units) may unlock significant cost savings per unit. Packaging also impacts logistics costs; options range from "Color Box" for individual retail or hospital ward use to "Export Standard Ctns" or "20PCS/CTN" for bulk shipping. Buyers should calculate the total landed cost, including packaging and shipping, rather than focusing solely on the unit price.

Typical Applications and Clinical Use Cases

Wall-mounted oxygen flowmeters with humidifiers are primarily designed for clinical environments where continuous and reliable oxygen delivery is necessary. The "Usage" attribute explicitly states compatibility with "Oxygen Tanks/Cylinders," making these units suitable for hospitals, clinics, and long-term care facilities. The "Group" attribute identifies the target demographic as "Adult," indicating that these specific models are calibrated for adult respiratory needs.

The inclusion of a 170ml reusable humidifier is specifically for "Oxygen Breathing," addressing the issue of dry gas delivery which can cause discomfort and tissue damage in patients receiving high-flow oxygen. This makes the equipment ideal for post-operative care, chronic respiratory disease management, and emergency room settings. The "Application" attribute lists "Transportation," which may imply that these units are robust enough for use in ambulances or mobile medical units, although the "Wall Type" designation suggests a fixed installation is the primary use case.

The "Purpose" is clearly defined as "for Oxygen Breathing," confirming the device's role in therapeutic gas delivery. The "Item Name" often includes descriptors like "Medical High Quality Tube-Flow Regulator," highlighting the dual function of flow regulation and pressure management. These devices are essential for ensuring that the oxygen delivered is not only at the correct flow rate but also at the correct pressure to prevent barotrauma while maintaining patient comfort through humidification.

Supplier Evaluation and Quality Assurance

When evaluating suppliers for medical oxygen flowmeters, buyers must look beyond the basic product listing. The "prod_origin" is consistently listed as "China," with specific mentions of "Ningbo, China" as a manufacturing hub. This geographic concentration suggests a mature supply chain but requires due diligence regarding the specific factory's capabilities.
