Abstract
In this study, we consider the nondimensionalized wound/slough interaction model [1] and develop it to have impulsive effects which can be stated as
𝑈𝑡=Δ𝑈+𝑁1(𝑈,𝑉),𝒙∈[0,1]𝑛,𝑡>0𝑉𝑡 = 𝐷Δ𝑉 + 𝑁2(𝑈, 𝑉) + 𝐼𝑖(V(𝑡𝑖, 𝒙)), 𝑖 = 0,1,2, …
where Δ is the usual Laplace operator for 𝑛=1,2,3; 𝐷 is a nondimensional parameter accounting for cellular diffusion; 𝑁1 and 𝑁2 are the reaction terms; 𝑈,𝑉 are the cellular density of wound and slough respectively. The impulsive effects are used to simulate medical treatment technique known as debridement [2] which is implemented at 𝑡=𝑡1,𝑡2,… to speed up the healing process, the 𝐼𝑖(.)’s are control functions to be determined to achieve optimal healing.
Keywords: Wound healing; Impulsive differential equations; Debridement.
