Harvest 250 Pump - Mid-Range Digital Pressure Pump for Active Mattresses.
- Four Selectable Therapy Modes - the Harvest 250 provides alternating pressure therapy, constant low-pressure mode (CLP), max inflate mode, and a dedicated seated mode; CLP maintains all cells at a consistent low inflation pressure for residents who cannot tolerate the movement of the alternating cycle; max inflate firms the surface for transfers and repositioning; seated mode adjusts pressure to the higher interface load associated with the resident sitting upright at 40-75mmHg, compared to the 18-55mmHg mattress range used in the lying position.
- Comfort Settings 1-8 Covering Under 30kg to 200kg - the eight comfort settings allow pressure to be calibrated to the resident's weight from under 30kg (setting 1) through to 200kg (setting 8); accurate weight-matched calibration is a clinical requirement for effective alternating pressure therapy because under-pressured cells bottom out under the resident's load while over-pressured cells do not conform adequately to the body profile; the setting documentation must be recorded in the equipment register alongside the resident's weight at the time of calibration.
- LED Display, Lockout, and Power Failure Alarms - the LED display shows current therapy mode and comfort setting with clear visual confirmation; the lockout function prevents unauthorised adjustment of settings by residents, visitors, or untrained staff; audible and visual alarms activate on low pressure, cycle fault, and power failure events; power failure alarm is particularly important for overnight monitoring in care homes where a pump disconnection or power interruption may go undetected without audible notification.
- Compatible with All Harvest Active Overlays and Replacement Mattresses - the Harvest 250 is compatible with the full range of Harvest active overlay and standard replacement mattresses, providing the widest mattress compatibility of any Harvest pump; it is not compatible with the bariatric 1200mm mattresses requiring the Harvest 3; EN60601-1 and EN60601-1-2 certified; voltage 230v/50Hz, fuse T 1AL 250V; 1.7kg; 275 x 175 x 116.5mm.
Harvest 250 Pump - Digital - 4 Therapy Modes - 200kg SWL - All Harvest Overlays and Replacements
The Harvest 250 is a digital mid-range pressure pump providing four selectable therapy modes - alternating, CLP, max inflate, and seated - for active mattress systems in community, residential, and nursing home settings. Eight comfort settings cover residents from under 30kg to 200kg. The LED display and lockout function support safe, consistent operation; audible and visual alarms cover low pressure, cycle fault, and power failure. Compatible with all Harvest active overlays and standard replacement mattresses. EN60601-1 and EN60601-1-2 certified. SWL up to 200kg on compatible mattresses.

Regulatory Compliance
The Harvest 250 meets EN 60601-1 and EN 60601-1-2 medical electrical equipment safety and electromagnetic compatibility standards. As the powered component of a Class IIa active medical device system under MDR 2017/745, the pump and connected mattress must be documented together in the equipment register with SWL verified against the resident's weight before deployment per MHOR 1992. Comfort setting must be documented at calibration alongside the resident's weight at the time. The lockout function must be engaged after calibration to protect the therapy setting. Power failure and low-pressure alarm functionality must be tested at deployment and the test result recorded for CQC Regulation 12 readiness.
Frequently Asked Questions
What is constant low-pressure mode and when is it clinically selected over alternating therapy?
Constant low-pressure mode maintains all air cells in the mattress at a consistent, simultaneously inflated low pressure rather than alternating between inflated and deflated states. The clinical effect is a uniformly soft, conforming surface that reduces interface pressure across the whole body contact area to the lowest level that maintains the resident above the mattress base. CLP is selected when the resident cannot tolerate the movement associated with the alternating cycle, which may be caused by severe pain from complex wounds, fractures, post-surgical conditions, or spinal instability where cell movement during the cycle causes distress or is clinically contraindicated. It may also be selected for short periods during medical procedures or examinations that require the resident to remain still. Alternating therapy remains the primary mode for pressure injury prevention and treatment per NICE CG179 because the dynamic offloading of each body zone in sequence provides greater tissue reperfusion than a static low-pressure surface; CLP is a supplementary mode for specific clinical indications rather than a routine alternative to alternating therapy.
How is the comfort setting calibrated for a specific resident, and can it be changed once set?
The comfort setting is selected by the prescribing clinician or therapist based on the resident's weight, with setting 1 appropriate for residents under 30kg and setting 8 for residents up to 200kg. The relationship between comfort setting and cell inflation pressure is designed so that the cells fully inflate under the resident's weight at the correct therapeutic pressure without bottoming out or over-inflating. After initial calibration, the carer should observe the mattress during use: cells that are visually flat under the resident after the inflation phase indicate under-inflation (setting too low); a surface that feels very firm with minimal conformation indicates over-inflation (setting too high). The lockout function should be engaged after calibration to protect the setting from inadvertent change. If the resident's weight changes significantly - weight loss exceeding 5kg or weight gain - the setting should be recalibrated and the updated setting and weight documented in the equipment register. The lockout must be disengaged by the authorised carer for recalibration and re-engaged immediately after.
