IEC 62366-可用性报告范例-Humidifier

Usability File MLD 9.05eBS EN 62366:2008Documentation of Compliance1 Inputs to the USABILITY SPECIFICATION1.1 Specification of the INTENDED USE/INTENDED PURPOSE1.1.1 DescriptionThe ACME Bubble Humidifier has been design specifically to be used with Oxygen. The unit can be used in most types of medical environments such as Hospital, Medical Centres, Ambulances and Domestic purposes.The humidifier works by conducting gas down the small internal tube that is submerged in water.The gas passes through the diffuser (sintered metal), which breaks the gas into small bubbles,increasing the surface area. The bubbles float passively to the surface, absorbing water vapour.The humidified gas then flows out through the outlet. The bottle component is moulded inautoclavable HDPE.The Humidifier has been designed to connect to Flowmetering Devices via a 9/16 Connector and that can provide a flow rates from 2 to 6 Lpm with a backpressure of 4 bar.1.1.2 EQUIPMENT application specification1.1.2.1 Medical purposeTo humidify the medical gas flow (Oxygen) to a patient e.g. via attached tubing and facemask.1.1.2.2 PATIENT populationa) Age: newborn to geriatricb) Weight: > 2.5 kgc) Health: not relevantd) Nationality: multiplee) PATIENT state:- PATIENT is not the OPERATOR1.1.2.3 Part of body or type of tissue applied to or interacted withNo direct contact with the patient – though attached tubing and facemask would contact noseand mouth.1.1.2.4 Intended OPERATORTrained medical or paramedical staff who understand how to connect to a flowmeter and the use of humidified oxygen.1.1.2.5 Applicationa) EnvironmentGeneral:- Hospital- Care Home/Hospice- Ambulance- Could be damaged by impact e.g. dropping or collision, then not function.- When functioning is shall keep humidifying the oxygen..Conditions of visibility:- Ambient luminance 100 – 500 lux- Viewing distance 20 cm to 1 metre- Viewing angle: normal to the scale ± 20°Physical:- Working pressure 400 kPa- Operation range 2 to 6 Lpm recommended- Permitted leakage - zero- Normal ambient conditions apply.b) Frequency of use:- Once a year up to 10+ times a dayc) Mobility:- Intended to be fixed to gas supply, which could be on a mobile trolley.1.2 PRIMARY OPERATING FUNCTION1.2.1 Frequently used functionsa) Filling with waterb) Reading scalec) Attaching to/removing from gas supply/flowmeterd) Attaching to patient tubing/facemask.e) Cleaning – can be sterilisedf) Storing1.2.2 Functions related to SAFETYa) Reading scale – especially when water supply exhaustedb) Supplying correct flow for condition/patientc) Cleaningd) Servicing & maintenance1.3 Risk analysis1.3.1 INTENDED USE/INTENDED PURPOSESee 1.11.3.2 USER PROFILESee 1.1.2.41.3.3 Things That could go wrongSources: Literature, Device Alerts, Sales, Healthcare Staff, Risk Analysis etca) During normal use:- Water has run out → level not visibleb) Use Errors:- Not refilling- Applying excessive force/mechanical stress/tampering- Dropping/Impact- Blockage- Leakagec) Environment:- Explosion when exposed to ignition sourced) Patient:- Tamperinge) Reading:- Not reading water level correctlyf) Hygiene:- Cross-contamination1.3.4 Task requirementsa) Clearly recognisable instructions on bottleb) Easily assembled/disassembledc) Readable/legible scaled) Easy cleaning of devicee) Light-weight designf) Easy to service & maintain1.3.5 The context of useSee 1.1.2.51.3.6 Information on HAZARDS known for existing deviceIncluded in 1.3.31.3.7 Resulting HAZARDOUS SITUATIONS and HARMSa) No humidification → improper treatmentb) Too much O2 administered over time – i.e. no CO2 content for breathing responsec) Ineffective therapy e.g. for COPD if Air rather than O2 administered/Hypoxiad) Introducing contaminants to the bodye) Used with patients whose supraglottic airways have been bypassed1.3.8 Preliminary review of the USER INTERFACE conceptNote: This review could be conducted utilizing a combination of cognitive walkthroughs, mock-up testing and early prototype testing.a) Connection into appropriate oxygen flowmeter:- Flowmeters labelled & body/knob colour coded (black – AIR;
