Help with Apex Page Redirect Controller.

Hey All. Hoping to get some help on a Controller issue I can't resolve. I'm pulling a parameter from a URL and using that in a SOQL query that will feed my redirect Parameter. Im getting a "Method does not exist or incorrect signature: void put(String, Account) from the type Map" error.

Here is my code. Thank you very much in advance.

public class MyController {

private final Account account;

public MyController() {
account = [SELECT FirstName,LastName,Measurement_Summary_ID__C FROM Account
WHERE Id = :ApexPages.currentPage().getParameters().get('recid')];
}

public PageReference validateAndRedirect(){

//Write your logic here and redirect
PageReference pageRef = new PageReference('/apex/Patient_Health_Dashboard');
pageRef.setRedirect(true);
pageRef.getParameters().put('id',account);
return pageRef;

}
}
