1. Characteristics of polyurethane foam dressing
(1)Good water absorption: can effectively absorb wound exudate, such as in the application of skin graft donor site, can absorb the blood, lymph and exudate secreted by the wound, keep the wound dry and clean, and the middle layer of the polyurethane foam of Medifone water absorption rate of 1020%.
(2)Good air permeability: It can keep the wound ventilated and help the wound heal, for example, the polyurethane foam dressing that may be required in the operating room or intensive care unit of a high-level hospital needs to have a high air permeability.
(3)Good softness: It can adapt to the shape of the wound in different parts, provide a comfortable fit, and has elasticity, can protect the wound and prevent the wound from being damaged again.
(4)Heat insulation: with low heat conduction performance, it can effectively isolate the transfer of heat and play the role of heat preservation and insulation, which is suitable for some special heat insulation engineering scenarios.
2, the function of polyurethane foam dressing
(1)Promotes wound healing
It provides a moist environment, which is conducive to the wound healing process. The PU film on the outer layer of Medifang can provide a moist wound healing environment, and the PU film on the inner layer is distributed with a large number of microholes with a diameter of less than 20 microns, which can prevent new epithelial cells from growing into the hole and promote wound healing.
It can adsorb and retain the growth factors and cells in the wound, accelerating the repair and regeneration of the wound.
(2)Reduce pain and itching: A protective layer is formed to effectively isolate the wound from external stimuli and reduce the occurrence of pain and itching. For example, in the trial of polyurethane foam dressing used in the skin graft donor area of burn patients, the pain in the experimental group was less than that in the control group.
(3)Protect the wound: soft, elastic and breathable characteristics, can adapt to different parts of the wound shape, prevent wound damage, but also has a certain antibacterial and decompression functions, in the case of special wound care can play a role.
