Regulator Jar Assemblies and Flowmeter Humidifier Bottles for Hospital Procurement Teams
Ward gas hardware is the part of a hospital nobody photographs and everybody depends on. A suction regulator that hesitates at the wall outlet, an oxygen flowmeter that reads vague at 4 L/min, a humidifier bottle that fogs the wrong way — each one turns a routine round into a maintenance call. For distributors carrying hospital accounts, these are also the items that move fastest and get reordered hardest, because they sit on every ward trolley rather than in a single theatre.
NINGBO HUASHENG MEDICAL EQUIPMENT CO.,LTD. builds exactly that layer of the medical gas chain: vacuum regulator jar assemblies, cylinder-mounted oxygen regulators with flowmeters, and wet oxygen inhaler sets with humidifier bottles. The range is designed for procurement teams who need consistent ward hardware they can stock, replace and re-order without re-qualifying a new supplier every season.
Vacuum Regulator Jar Assemblies: Suction Control Built Around the Gauge
The suction side of the catalogue is led by a regulator assembly that mounts directly onto a graduated collection jar, so the reading and the collection sit in one hand-held unit. The chrome-plated body carries an analog vacuum gauge scaled in MPa, marked from 0 through 0.02, 0.04, 0.06 and 0.08 with a negative end at -0.1, giving clinical staff a clear dial to work against rather than an anonymous knob. A color band on the dial face marks the working zone so a nurse can confirm the setting at a glance during a busy round.
Control is a rotary valve with three molded positions — VAC, OFF and NO — printed with a directional arrow on the knob face. That is a deliberate design choice: it means suction is either on, isolated, or vented, and the state can be read without turning the device to find a label. The regulator connects to the jar through a metal cap fitting, and the jar itself carries a printed graduation in millilitres.
The images show two jar configurations. The larger unit uses a 500 ml clear jar with a bright lid secured by two stainless side latches, a robust arrangement for wards where jars are handled, emptied and re-seated several times per shift. The smaller unit uses a 200 ml jar with a screw-on domed lid and a molded outlet nozzle, sized for bedside and transport use where a compact footprint matters more than volume.
Both jars are transparent with molded volume markings, so fluid level is visible from across the trolley. Both assemblies use the same chrome regulator head and the same gauge format, which simplifies spares holding — one head type, two jar sizes, fewer part numbers on the shelf.
Wet Oxygen Inhaler Sets: Flow Tube, Humidifier and Outlet in One Body
The oxygen side of the range is a wet-type inhaler built around a vertical tapered flow tube with a visible float ball, mounted on a polished metal body with a knurled control knob and an oxygen outlet nipple. The label on the body identifies the model series as HS-KRQ-1, states a flow range of 1–10 L/min and an accuracy class of 4, together with the production date, lot number and a PA marking.
Below the body sits the humidifier bottle, molded in clear material with a green dip tube running down the centre and a colored collar at the joint. The bottle is filled to the marked line; gas passes through the water column and arrives at the patient warmed and moistened rather than dry. Three bottle variants appear across the catalogue photos — a deep teal body with green fittings, a lighter teal body with a green cap and side nozzle, and a variant with a green lid and larger collar — which gives buyers room to match existing stock or standardize on one colour for a ward.
Fittings are a practical detail worth flagging. The outlet is a stepped metal nipple that accepts standard oxygen tubing, and the inlet side uses a threaded metal connector with a knurled collar so the set can be attached to a wall outlet, a regulator outlet or a cylinder yoke depending on the configuration ordered. The body-to-bottle joint is threaded, so bottles can be removed for cleaning and refilling without disturbing the flow setting above.
Cylinder-Mounted Regulator and Flowmeter Combinations
For cylinder-based oxygen supply there is a combined unit: a chrome-plated pressure regulator with a green anodized adjusting knob, feeding a horizontal flow tube with a graduated scale, with the humidifier bottle mounted at a right angle. The pressure gauge is scaled 0 to 25 MPa, and the green knob carries a directional arrow for opening the supply. Because the flow tube sits horizontally, the float reads correctly whether the cylinder stands upright or is laid in a trolley bracket — a detail that matters in recovery rooms and ambulance stock.
This configuration is the one most buyers order in volume. One part number covers cylinder connection, pressure indication, flow control and humidification, which reduces the number of fittings a hospital stores and the number of connections that can be assembled incorrectly at 3 a.m.
Where These Products Earn Their Place
The realistic order book for this range looks like this: general wards and isolation rooms needing bedside suction with a visible collection jar; emergency departments and triage where suction must be reachable in seconds; operating theatres and recovery where a horizontal flow tube fits a rail-mounted setup; ambulance and transport kits where the compact 200 ml jar assembly is the right size; nursing homes, clinics and dental surgeries running lighter but continuous suction; and oxygen therapy corners in respiratory units where humidified delivery is standard practice.
What Distributors Should Actually Check Before Ordering
Three things decide whether this kind of hardware sells well in a market.
Connection standards come first. Wall outlets and cylinder valves differ by country and by hospital. Buyers should confirm the inlet fitting thread and outlet nipple diameter against the gas outlet standard used in their market before placing a first order, and confirm the connector for each SKU in writing.
Then consumable logic. Jars, bottles and tubing get replaced far more often than regulator heads. A supplier that can ship bottle and jar components separately — in consistent colours and with matching threads — saves the buyer from scrapping an entire assembly because a single jar cracked.
Then documentation. Product labels carrying model number, flow range, accuracy class, production date and lot number do more than satisfy auditors; they let a service engineer in year three identify exactly which batch a unit came from. Buyers evaluating a new supplier should ask to see the label layout before the first shipment, not after.
Working With Ningbo Huasheng
The company operates from Kandun Industrial Zone in Cixi, Zhejiang — the export belt that has supplied medical gas fittings and instrument hardware worldwide for decades, with the component and machining supply chain on the doorstep. The product line is deliberately narrow: regulator heads, graduated jars, oxygen flowmeters with humidifier bottles, and the fittings that connect them. That focus makes for straightforward sourcing conversations, because the answer to a technical question about a jar thread or a gauge scale sits with the people who build the assembly rather than three tiers up a supply chain.
For distributors, the practical benefit is range coherence. A single supplier covering vacuum regulation, oxygen flow control and humidification means one set of connection standards, one set of bottle colours, and one spares catalogue across an entire ward gas programme.
Next Step
If you are building or refreshing a ward gas hardware line, send your required connection standards, jar volumes and flow ranges, and ask for a quotation matched to your market's outlet configuration. Sample orders and mixed-container loads are the usual starting point for new distributor relationships.
