Visionstar LS-HV

Three Stage Pulse Vacuum

Three pulse vacuum stages reach minus 0.081 MPa, which the manufacturer relates to completely extracting inner air from dressings and from type A and type B hollow appliances.

Vacuum Drying After Sterilising

Multiple pulse vacuum drying follows on from the sterilising stage, which the manufacturer relates to a good sterilising result on the loads that are being processed.

Fully Automatic Route

Water inlet, pulse vacuum, heating, sterilising, draining, exhausting and vacuum drying are all described as running automatically under microcomputer control.

Four Fixed Programs

Programs cover appliance, medical dressing, rubber and fluid loads, and the manufacturer states that a program can also be set as the individual user requires.

Bacteria Filter

A bacteria filter ensures the air entering the vacuumed chamber is sterile, which the manufacturer relates to avoiding second time contamination of a processed load.

Comprehensive Display

The digital display shows temperature, pressure, time, vacuum rate and cycle status dynamically, operated through touch type keys upon the front panel.

Three Chamber Capacities

Volumes of 50L, 75L and 100L are offered, at 340 by 550mm, 400 by 600mm and 440 by 650mm, all sharing 0.22 MPa working pressure and a 134 degree working temperature.

Testing Connector and Heating

A PY/TT testing connector is fitted specifically for running tests, and an immersed heating tube is described as providing high heating efficiency throughout the whole cycle.

Hollow Instruments and Lumened Devices

This is the case pulse vacuum exists to address. Steam cannot reach the inside of a lumen while air remains there, and a gravity vessel relying on displacement cannot be relied upon to clear it. Three vacuum pulses extract that air actively before heating, which is exactly why the manufacturer names type A and type B hollow appliances specifically among the loads that this particular range is intended to process.

Wrapped and Packaged Loads

Wrapped packs present much the same difficulty as hollow devices, since the wrapping holds air against the instruments held inside it. Pulse vacuum removes that air, and vacuum drying afterwards means the pack leaves the chamber dry rather than damp. A damp pack can draw contamination through its own wrapping as it cools, so both stages matter a great deal indeed for anything destined for storage.

Laboratory Media and Mixed Loads

Four fixed programs covering appliance, dressing, rubber and fluid loads acknowledge that these materials all behave differently and need different handling. Fluid loads in particular require care that an instrument program does not provide. That a further program can be set as required gives a laboratory scope to define its own conditions for its own particular materials.

Departments With Validation Requirements

A PY/TT testing connector is provided specifically for running tests, and the display also reports the vacuum rate alongside the temperature, pressure and time. For a department that must demonstrate air removal and steam penetration are both working, equipment built to be tested is considerably easier to govern than equipment that merely runs a cycle and then reports nothing.

Air Removed Rather Than Displaced

The difference between this range and a gravity vessel is fundamental rather than incremental. Three vacuum pulses to minus 0.081 MPa actively extract air from lumens and packs before steam is admitted, where a gravity machine depends on steam pushing air ahead of it and cannot guarantee the result in a hollow device. For any department processing lumened instruments, that distinction determines whether the equipment is fit for the work at all in the first place.

Dry Loads and a Dry Room

Vacuum drying leaves packs dry enough for storage, and the steam water inner circulation system means no steam is discharged into the room. Those two together address both ends of the problem: a load that would otherwise come out damp, and a working space that would otherwise need ventilation sized for repeated steam releases throughout the whole of a working day.

Built to Be Tested and Controlled

A dedicated testing connector, a display reporting vacuum rate alongside temperature and pressure, four defined programs and the ability to set another mean this range suits a department that has to document what it does. Equipment that reports its own conditions and accepts routine testing is far simpler to bring into a written decontamination procedure than equipment that offers only a start button.

The Visionstar LS-HV range offers three vertical pulse vacuum sterilisers at 50L, 75L and 100L, with chambers of 340 by 550mm, 400 by 600mm and 440 by 650mm. All three share 0.22 MPa working pressure, 0.23 MPa maximum, a 134 degree working temperature, heat average within plus or minus 1 degree and a 0 to 99 minute timer. Three pulse vacuum stages reach minus 0.081 MPa, vacuum drying follows sterilising, four fixed programs are provided with a further one settable, and a bacteria filter, PY/TT testing connector, immersed heating tube, microcomputer control, hand wheel quick open door, self inflating seal and steam water inner circulation are all fitted.

Two rows need checking rather than accepting. The temperature adjust range is printed as 0 to 134 degrees, and a lower bound of 0 degrees is not a meaningful sterilising condition. The bacteria filter rating is printed in a garbled form and has not been reproduced as a figure here. Both should be confirmed with Medigear.uk. The electrical specification is likewise not reproduced, and nothing here should be read as a claim about testing or regulatory approval.

If your department processes hollow instruments or wrapped packs, or has to demonstrate air removal as part of a decontamination procedure, speak to Medigear.uk. As a verified medical equipment supplier working across medical, dental, rehabilitation and aquatic therapy settings, the team will confirm which capacity suits your loads and what documentation accompanies it.
