Most ward gas installations are not judged by the pipeline behind the wall. They are judged by the hardware a nurse clips onto the outlet at three in the morning. If the flowmeter float sticks, or the lid of a suction jar fails to seal, the entire installation takes the blame. NINGBO HUASHENG MEDICAL EQUIPMENT CO.,LTD. builds at that level — the bedside connection, the bottle in the nurse's hand, the knob a patient's family member may turn without training.
Our catalogue covers three families that sit on the working end of a hospital gas system: wet oxygen inhalers (flowmeter with humidifier bottle), vacuum regulators with graduated collection jars, and cylinder pressure regulators. They are simple devices. That is exactly why they are hard to build well — nothing hides a bad seal, a stiff valve or a faded scale.
Wet oxygen inhalers: flowmeter and humidifier in one body
The inhaler shown in our range carries the model designation HS-KRQ-1, with a stated flow range of 1–10 L/min and an accuracy class printed on the body label. The design is the classic wet type: oxygen enters a chrome-finished metal body, passes through a needle valve controlled by a ribbed knob, and is bubbled through sterile water in a transparent humidifier bottle before reaching the patient's cannula or mask.
What matters to a buyer is what the photographs make plain. The tapered metering tube is clear and generously sized, so the float reads easily from a standing position rather than requiring a nurse to lean in over a bed. The scale is engraved alongside the tube, not printed on a sticker that lifts after a year of disinfectant. The humidifier bottle is a single-piece transparent cylinder with a wide mouth, a moulded diffuser stem running down the centre, and a screw collar that seats the body with a quarter turn. Some variants in the range use a green-tinted bottle and a green top cap, others a clear body with a blue control knob — useful for colour-coding by department or by market preference.
The outlet nipple is a stepped metal spout sized to take standard oxygen tubing and held by a knurled retaining nut, so the fitting can be swapped for a different connector standard without replacing the whole inhaler. The inlet side is a matching knurled fitting that tightens onto the wall outlet or cylinder yoke by hand. Both are chrome-plated, both survive the wipe-down routine that plastic fittings slowly lose.
Vacuum regulators with graduated collection jars
The suction side of the range is built around a regulator body with an integrated diaphragm gauge and a three-position rotary selector marked VAC, OFF and NO. That selector is the piece of user-interface design worth pointing out to distributors: the positions are visible from arm's length, the knob has a positive detent at each stop, and the OFF position sits physically between the two working modes. A clinician reaching for suction in a hurry can see, not guess, what state the device is in.
The gauge face reads in MPa on a scale from -0.1 to 0.06, with colour bands marking the working and warning zones. Two jar sizes appear in the range: a 500 mL graduated cylinder with a bright orange lid and stainless over-centre side latches, and a 200 mL cylinder with a white domed lid and a screw collar. Both jars carry moulded graduations in blue with 100 mL intervals on the larger unit and 50 mL intervals on the smaller, plus a fill-temperature reference moulded into the base. The lids carry an angled patient port and a straight vacuum port, both barbed to grip tubing.
For a distributor, the jar is the consumable half of the product. Lids crack, cylinders cloud after repeated washing, and gaskets harden. A supplier who can ship replacement bottles and lids as separate line items keeps a hospital buying for years instead of once.
Cylinder regulators
The third family is the cylinder-side regulator: a chrome-plated brass body with a 0–25 MPa high-pressure gauge, a large green control knob and a hex inlet nut for the cylinder connection. The dial carries a clear prohibition mark against oil and grease — standard practice for any oxygen-wetted component, and a detail that tells an inspecting buyer the labelling was thought through rather than pasted on.
Where these devices actually live
Ward and ICU bedside outlets account for the bulk of demand, but the same hardware turns up in recovery rooms, emergency bays, ambulance interiors, dialysis units, neonatal stations, dental surgeries and small clinics where a single wall outlet has to serve several functions across a day. Oxygen concentrator installations in home-care programmes also use wet inhalers to humidify dry concentrate output. Suction regulators with collection jars are equally at home in operating theatres, delivery rooms, wound-care clinics and veterinary practices.
That spread of end users is the reason a mixed container works: flowmeters, vacuum regulators, jar sizes and cylinder regulators can be combined in one order, matched to the fittings a given market expects.
What buyers should look at before ordering
First, gauge units. The MPa face used across our range suits most of Asia, Europe and Latin America. Markets working in kPa, bar or cmH2O need the dial confirmed at the quotation stage, because a unit mismatch is the most common reason a shipment arrives technically correct and clinically unhelpful.
Second, inlet fittings. Wall outlets differ by country and sometimes by hospital. Confirm the connector standard — the body, valve and bottle stay the same; the inlet adaptor changes.
Third, the consumable plan. Distributors who bundle replacement bottles, lids and gaskets into their first order avoid the situation where a working regulator is idle for want of a two-dollar part.
Fourth, labelling. Model code, flow range, accuracy class and manufacturer name belong on the body, permanently, in a form that survives disinfection. Ours are printed on metal.
