By sticking a fixed method improvement can reduce sticking curl, avulsion. Traditional apply fixed method will associate labels fixed distance patches outside edge 2 ~ 3 cm catheter, insulin activity in patients with easy pull catheter, deputy label will be smaller tore off, if not properly disposed of as follow-up activities pull catheter, and make the patches curly degloving slip until a needle. And the improved apply fixed method will associate labels overlap in patches near catheter edge is 0.2 ~ 0.3 cm, not only enhances the transparent apply the paste viscosity, is not influenced by patients when pull catheter, so difficult to apply the paste curly, avulsion and needle sliding out events. Sticking fixed improvement method can enhance the robustness, needle in subcutaneous move not easily, not easy to happen patches curly degloving, bleeding and needles slippage, and the pain in patients with discomfort also greatly reduced. 1.2 method 1.2.1 Group apply traditional fixed method By insulin pump embedded operation flow pump, put the transparent after sticking above fixed in the needle, needle is located in the patches are central, deputy labels will apply (fill in the date, time, signature) stick to 2 ~ 3 cm from sticking edges, fixed on the insulin pump tube, properly placed insulin pump, informed patient attention with pump. 1.2.2 improvement group sticking fixed method Pump flow with the traditional group, put the transparent after sticking above fixed in the needle, needle is located in the patches are central, will apply vice labels to stick on transparent edge patches (near the catheter end), the deputy edges overlap in sticking label 0.2 ~ 0.3 cm, properly placed insulin pump, give attention to patients.
