在Excel VBA中实例化另一个类中的对象

I'm working on a project using Excel VBA where I have a number of datasets, each populated with a number of 'patients' which have a number of parameters (such as treatment, outcome etc.). To handle this, I intend to create a class called 'patient', with properties such as treatment and outcome. Then create a class called 'dataset', with a public property of 'patient'. I've created the classes, and I can instantiate a dataset object. But how do I go about instantiating patient object, or ideally an array of patient objects within the dataset object?I'm working on a project using Excel VBA where
