Blackstone's CO2 insufflator fills the abdomen with carbon dioxide at a controlled pressure. That creates the working space for laparoscopic surgery and holds it steady as gas escapes through ports and suction. The target pressure can be anywhere from 5 to 30 mmHg. The photograph shows a panel titled gas insufflator, with readouts that appear to be labelled setting value and actual value in mmHg. There is also a flow readout in L/min and a fourth display with a reset key beneath it, which may count the gas used.

Flow is the figure to check. The sheet gives it as 10 to 30 L and stops there, without saying per minute, although the label on the flow readout points to litres per minute. Read that way, even the bottom setting is higher than the 1 to 3 L/min commonly chosen when gas first enters through a Veress needle. The needle's narrow bore holds flow down on its own, but a dedicated low flow start is still worth confirming. A flow key with three small lights beside the readout suggests stepped settings rather than continuous adjustment.

The pressure range fits the stages of a case. RCOG guidance on laparoscopic entry recommends 20 to 25 mmHg before the first trocar goes in, then 12 to 15 mmHg for the operation. The European Association for Endoscopic Surgery advises the lowest pressure that still gives an adequate view.

All of these sit between 5 and 30 mmHg. What the sheet leaves out is the safety side: over-pressure alarms and venting, occlusion warnings, low supply alerts, ts and the filter on the patient line. Medigear.uk is raising each with Blackstone before this CO2 insufflator is supplied.

Every laparoscopic list depends on the insufflator, whether the case is a cholecystectomy, an appendicectomy, a hernia repair, bowel surgery, or a gynaecological procedure. Entry is the first moment of risk. As gas starts to flow through the Veress needle, the team watches the actual pressure, and RCOG notes that a low opening pressure, under 8 mmHg, with gas flowing freely is the most useful sign of correct placement. The separate actual pressure readout supports that check.

Pressure has physiological consequences. A raised intra-abdominal pressure reduces venous return and splints the diaphragm, while absorbed carbon dioxide raises blood CO2, which the anaesthetist offsets through ventilation. The EAES guideline therefore recommends the lowest pressure that gives adequate exposure, and it treats end-tidal CO2 monitoring as mandatory during laparoscopy. The 5 mmHg floor allows low-pressure work, which the same guideline places at 5 to 7 mmHg.

Gas supply needs planning too. Carbon dioxide is chosen because it does not support combustion besides diathermy and dissolves readily in blood, which makes any embolism less dangerous than one of air. The photograph shows an adjustable two-gauge cylinder regulator and a blue hose, so the unit appears to run from a cylinder. That regulator must suit the valve on the hospital's medical CO2 cylinders and deliver the inlet pressure the insufflator expects, and neither detail is stated. A spare cylinder belongs on hand for long cases, and any low supply warning needs confirming.

Medigear.uk has asked Blackstone for the inlet pressure, the cylinder connection,n and the alarm behaviour of this CO2 insufflator.

Entry and Operating Pressures in One Range

Five to 30 mmHg spans the 20 to 25 mmHg often used for trocar entry and the 12 to 15 mmHg typical during surgery.

Room for Low-Pressure Work

The 5 mmHg floor allows the low-pressure pneumoperitoneum that European guidance describes at 5 to 7 mmHg.

Set and Actual Pressure Side by Side

Separate readouts, as the photograph shows, let staff compare the target with the pressure the abdomen has reached.

A Readout for Flow

Seeing flow in L/min helps the team judge how much gas is escaping through ports or suction.

A Possible Gas Volume Counter

A fourth readout with a reset key may track the gas used, which would help staff spot a leak.

Quiet Operation

A noise ceiling of 50 dB suits equipment that runs beside the team for the whole case, pending the weighting.

Low Power Draw

At 40 VA, this CO2 insufflator places little load on the stack's electrical supply.

No Transformer Needed

Any mains supply between 100 and 240 volts, at either frequency, powers the unit wherever it is installed.

Pressure Range

5 to 30 mmHg.

Flow Range

10 to 30, printed in litres without a time unit.

Readouts

Supply Indicator

Three lights under a pressure label.

Gas Outlet

Metal connector on the front panel.

Noise

50 dB or less.

Rated Power

40 VA.

Stated Application

Laparoscopic surgery.

On paper, the Blackstone CO2 insufflator covers the pressures a laparoscopic list needs, from a 5 mmHg low-pressure setting to the 20 to 25 mmHg used for entry, with a readout for the pressure reached beside the target and a quiet, low-power design. The open questions concern flow and safety. Flow is printed without a time unit; its lowest setting is higher than the rate usually chosen to start through a Veress needle, and no alarms, venting, or filter are described. The gas supply also needs defining, from the cylinder connection to the inlet pressure. Medigear.uk has put all of this to Blackstone and will share the answers with the surgeons, anaesthetists and engineers weighing up a new insufflator for their theatres.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

It creates the pneumoperitoneum for laparoscopic surgery and then keeps it at the set pressure, topping up the gas lost through ports, instrument changes, and suction. The target can sit anywhere in its 5 to 30 mmHg range, and the photograph shows readouts for that target, the pressure actually reached, and the flow. Blackstone names laparoscopic surgery as the application.

The sheet omits the time unit, so the figure is incomplete as printed. The label under the flow readout in the photograph points to litres per minute, the usual unit for insufflators, and that is the most likely meaning. The three lights beside the flow readout also suggest the flow is chosen in steps rather than set freely, and Blackstone is being asked to confirm both points.

It can supply the gas, but the details matter. Guidance from RANZCOG suggests starting insufflation at a low flow such as 1 to 3 L/min, and this unit's lowest listed flow is higher. A Veress needle restricts flow by its narrow bore, which limits the effect, yet many insufflators include a separate low-flow mode for entry, and none is confirmed here. The actual pressure readout lets the team check the opening pressure as gas begins to enter.

It runs from a floor of 5 mmHg to a ceiling of 30 mmHg. The RCOG Green-top Guideline on laparoscopic entry advises building to 20 to 25 mmHg ahead of the primary trocar and dropping to 12 to 15 mmHg once the trocars are in place, and both fall inside that range. European guidance favours the smallest pressure that still exposes the field, and the 5 mmHg floor leaves room for low-pressure technique.

The sheet lists none. Only the paired display of target and actual pressure shows up in the photograph as a safety aid. An insufflator is normally expected to warn when pressure exceeds the set value and to vent the excess, to flag a blocked line and to alert staff when the gas supply runs low, and Blackstone has been asked which of these this CO2 insufflator provides.

The photograph shows a brass cylinder regulator with two gauges and a blue hose, which points to a cylinder feed. The inlet pressure, the cylinder valve connection, the medical certification of that regulator, and any option for a piped CO2 supply are all unstated. Those details decide whether this CO2 insufflator will connect to the cylinders a hospital already uses.

No heater is described, so the gas will enter at the temperature of the supply. A hydrophobic filter on the patient line normally protects both the patient and the unit from contamination and fluid backflow. The clear tubing in the photograph may carry one, but the sheet does not say so, so the filter specification has been requested along with the tubing details.

Beyond flow, filter, and alarms, the open items are the model number, the gas inlet specification, the electrical classification,n and the regulatory position under CE or UKCA marking. Physical data are also missing, including weight and the size of the unit and its carton, and so are warranty terms and delivery lead time. Every item has gone to Blackstone together.
