Suction Units & Vacuum Extractors Lab Equipment Manufacturer, Supplier and Exporter in India

This listing holds 23 items in the SUVE series, SUVE-0001 to SUVE-0023, and it contains two entirely different kinds of device that happen to share the word vacuum. Suction units are aspirators for clearing airways and fluids. Vacuum extractors are obstetric instruments for assisted delivery. They are not related and their accessories are not interchangeable, so check which family an item belongs to before you quote it.

The two families

Note that the suction cups at SUVE-0016 and SUVE-0017 are ventouse cups for the vacuum extractors, not accessories for the aspirators. Note too that the Malmstrom pattern is spelled Malstrom in the listing.

Suction units: two numbers, and you need both

A suction unit is defined by a pair of figures, and a quotation that gives only one tells you half the story:

One further figure is worth asking for: the time to reach working vacuum. One unit in this listing states that it reaches its vacuum within 45 seconds, which is the sort of figure that matters at a bedside.

Note that two codes label a figure in mmHg as a flow rate. A figure in mmHg is a pressure, not a flow, so treat that as the vacuum level and ask separately for the displacement in litres per minute.

A vacuum regulator is not optional

For airway suction, and especially for paediatric and neonatal airway suction, the vacuum must be regulated and limited, because excessive vacuum injures mucosa. So on any unit intended for airway use, confirm that a vacuum regulator and a readable gauge are fitted, that the vacuum can be set low as well as high, and what the lowest settable level is. A unit that only runs at its maximum is a theatre or field aspirator, not an airway unit for a children's ward.

The rest of the suction specification

• Pump type. The listing names oil rotary and piston pumps. An oil rotary pump reaches a high vacuum but needs oil checks and changes; a piston pump is oil-free and lower maintenance; a diaphragm pump is oil-free but reaches less vacuum. Ask which is fitted and what the maintenance schedule is, and for an oil-immersion unit ask which oil and how often.
• Overflow protection. Ask whether a float or shut-off valve prevents fluid reaching the pump. This is the single feature that most often decides whether a suction unit survives its first serious use.
• Bacterial filter. Whether one is fitted, and the replacement part number and price.
• Jars. Capacity, number of jars, material, whether autoclavable, and whether graduated. Ask the price of a spare jar; a dropped jar should not take the unit out of service.
• Duty cycle. Whether the unit is rated for continuous or intermittent running. A theatre unit needs a continuous rating.
• Power and fallback. The dual-mode electric-plus-foot machines and the battery and AC/DC units exist for places where the supply fails or does not reach. For a battery unit ask the runtime and recharge time; for an ambulance, confirm the DC voltage.
• Noise and mounting. Noise level, and whether the unit is a trolley model, portable or bench. The trolley model (SUVE-0021) is the theatre pattern.
• Consumables. SUVE-0019 is tubing and SUVE-0023 is a standard consumables item. Ask exactly what the consumables item contains, and order tubing and catheters with the machine.

Vacuum extractors: the cup is the decision

Three extractors and two cup materials are listed, and the choice of cup is a clinical one rather than a price one.

For any extractor, ask for the cup sizes available, whether the gauge is clearly readable in the units your protocol uses, whether the vacuum can be raised gradually and released quickly, and the permitted sterilisation method and cycle count for the cups. The vacuum level used is set by your own clinical protocol, so confirm the gauge covers that range with usable resolution.

Before ordering

Suction units and vacuum extractors are regulated medical devices. Confirm the registration or clearance each item holds in your country of use and verify it with your own regulator. Several product titles here carry model or brand names rather than specifications, and two differ only by a numeral suffix; ask the sales team to confirm in writing what distinguishes them and exactly what is supplied against each code. Any performance figure quoted is confirmed in writing on the quotation. Ray Export supplies the equipment and holds no approval on your behalf.

Request a quote

For a suction unit, give the vacuum and the free air displacement you need, say whether it is for airway use and therefore needs a regulator, and state the power arrangement. For an extractor, give the cup material and sizes. For example High Flow Suction Unit (SUVE-0002) with a regulator, two autoclavable jars and spare tubing. Contact Ray Export for prices, specifications and lead times.

Frequently asked questions

Are the suction cups SUVE-0016 and SUVE-0017 accessories for the suction units?

No. Despite the name, SUVE-0016 (silicone) and SUVE-0017 (stainless steel) are ventouse cups for the obstetric vacuum extractors, not accessories for the aspirators. This listing combines two unrelated families that share the word vacuum: suction units for clearing airways and fluids, and vacuum extractors for assisted delivery. Check which family each code belongs to before you quote it, and order tubing (SUVE-0019) and catheters with a suction machine rather than assuming the cups fit it.

Which two figures define a suction unit?

The vacuum level in mmHg, which governs how strongly the unit lifts, and the free air displacement in litres per minute, which governs how fast it clears. Units here state vacuum figures including about -550, -650, -710 and -720 mmHg, and displacement from about 15 L/min on the portable unit to 30 to 38 L/min on the mains units. A high vacuum with a low flow evacuates slowly; a high flow with a low vacuum will not lift thick secretions. Two codes label an mmHg figure as a flow rate, so ask separately for the displacement.

Does a suction unit for airway use need a vacuum regulator?

Yes. For airway suction, and especially paediatric and neonatal airway suction, the vacuum must be regulated and limited, because excessive vacuum injures mucosa. On any unit intended for airway use, confirm that a vacuum regulator and a readable gauge are fitted, that the vacuum can be set low as well as high, and what the lowest settable level is. A unit that only runs at its maximum is a theatre or field aspirator, not an airway unit for a children's ward. Ask too how long it takes to reach working vacuum.

Which pump type and safety features should a suction unit have?

The listing names oil rotary and piston pumps. An oil rotary pump reaches a high vacuum but needs oil checks and changes; a piston pump is oil-free and lower maintenance; a diaphragm pump is oil-free but reaches less vacuum. For an oil-immersion unit ask which oil and how often. Ask whether a float or shut-off valve stops fluid reaching the pump, the feature that most often decides whether a unit survives its first serious use, and whether a bacterial filter is fitted, with its replacement part number.

Which suction units suit theatre, wards without reliable power, or ambulances?

A theatre unit needs a continuous duty rating; the trolley model SUVE-0021 is the theatre pattern. Where the supply fails or does not reach, the dual-mode electric-plus-foot machines, the foot-operated units and the battery and AC/DC units are the options. For a battery unit, ask the runtime and recharge time, and for an ambulance confirm the DC voltage. For any unit, ask jar capacity, number and material, whether jars are autoclavable and graduated, the noise level, and whether spare jars are available so a dropped jar does not take the unit out of service.

Which vacuum extractor cup should we choose?

The choice is clinical. The rigid metal Malmstrom pattern (SUVE-0013, SUVE-0017) holds better on difficult and rotational positions at the cost of more scalp marking. The Bird type SUVE-0014 is a modified rigid pattern with central traction. The soft silicone cup SUVE-0016 is gentler and generally preferred for straightforward positions but more prone to detaching. SUVE-0013 and SUVE-0014 are manual with the hand pump SUVE-0018; SUVE-0015 is electric. Ask the cup sizes, gauge units and resolution, gradual raise and quick release, and the sterilisation method and cycle count for the cups.

Key takeaways

• Two unrelated families: suction units and obstetric vacuum extractors share a listing but not their accessories.
• Read both suction figures: vacuum in mmHg and free air displacement in L/min decide performance together.
• Airway use needs a regulator: confirm a readable gauge and a low settable level, especially for paediatric and neonatal suction.
• Overflow protection saves the pump: ask whether a float or shut-off valve is fitted, and whether there is a bacterial filter.
• Match power to the setting: continuous duty for theatre, foot, battery or AC/DC units where the supply is unreliable.
• The extractor cup is a clinical choice: rigid metal, Bird type or soft silicone, with manual or electric vacuum.
