Probably you are looking for something (google "Oracle table functions"):
SQL> create table my_tab(pin VARCHAR2(7))
2 /
SQL> declare
2 arr INJURED_PEOPLE := INJURED_PEOPLE();
3 begin
4 arr.extend(2);
5 arr(1) := INJURED_PERSON('APIN',null,null,null,null,null,null);
6 arr(2) := INJURED_PERSON('BPIN',null,null,null,null,null,null);
7 INSERT INTO my_tab SELECT x.PIN FROM table(arr) x;
8 end;
9 /
SQL> select * from my_tab;
PIN
-------
APIN
BPIN
