One of these disadvantages is high price that the majority of the patients cannot afford; the other is large volume that is not easy to carry;another disadvantage is lack of reliabilityand stability in some simple negative -pressure devices despite their low prices.
In order to overcome the above disadvantages and meet the clinical needs of patients, this paper has referred to the Guidelines for Negative Pressure Wound Therapy in Europe, used the hospital’s existing materials and self-designed a pocket-type negative-pressure wound closure device.
This device is characterized by small volume (may be put into pockets), adjustable negative pressure, low price, reliable performance . This device can reduce the cost of high technology and belongs to a leading technology in China. This device can shorten the healing time of chronic wounds in clinical practice and reduce the total cost of the therapy, which conforms to the current situation of Chinese people’s livelihood and is widely recognized by the majority of patients. This device has obtained three China National Utility Model Patents in 2014, with patent No. 201420305835.3, 291420305940.7 and 201420305942.6 respectively.
