This is the face of 91-year-old Ivy Bellamy, battered and bruised in her Harrow home after she was left in the hands of professional carers.  
Less than four months later the great-grandmother's head was smashed open in another accident forcing her to spend 12 days in Northwick Park Hospital.
Her devastated sons are demanding to know why Care UK Harrow, which provides home care to about 350 people in the borough, let this happen to their vulnerable mother.
Raymond Bellamy, 59, who lives with Ivy and his father Richard, 94, in Worple Way, Rayners Lane, said: "The first time mum was injured I went straight to the hospital where she was by herself.
"Her face was so bruised I walked straight past her. I didn't recognise my own mum."
Mrs Bellamy, who has dementia, had been hit in the face with the arm of a hoist while under supervision of Care UK Harrow.  
The group continued visiting Mrs Bellamy but on July 26 Raymond found his mother in her bedroom with blood pouring from her head.
It is believed she slipped through a sling attached to the hoist during a home visit and split her head open. It later emerged the wrong sling had been used.
Brother Alan, 62, who lives in Sandringham Crescent, said: "Because of her dementia mum can't yell out, she can't communicate.
"We were totally devastated. You could tell by her face she was in shock, in pain and finding it hard to breath. When we found out the wrong sling had been used we demanded an investigation and a re-enactment which should have been carried out after the first incident.
"Why were they using the wrong equipment and where did it come from? For this to happen twice in four months is unbelievable."
The re-enactment was carried out on August 1 which proved the wrong equipment had been used and the sling was taken away.
A spokeswoman for Care UK said: "Care workers acted correctly and in accordance with best practice.
"Following the investigation social services have installed a different type of sling at the property. Mrs Bellamy's sons have since confirmed they are happy for Care UK to continue to provide care for their mother."
Harrow Council, which has a contract with the group, says an investigation is ongoing.
Councillor Barry Macleod-Culliane (Conservative), responsible for adults and housing, said: "To ensure that any further concerns and queries have been fully addressed the council has arranged for a care manager to contact them immediately and we are closely monitoring the delivery of the care contract."
