Creating a new HL7 message
# create a message
msg = HL7::Message.new
# create a MSH segment for our new message
msh = HL7::Message::Segment::MSH.new
msh.recv_app = "ruby hl7"
msh.recv_facility = "my office"
msh.processing_id = rand(10000).to_s
msg << msh # add the MSH segment to the message
puts msg.to_s # readable version of the message
puts msg.to_hl7 # hl7 version of the message (as a string)
puts msg.to_mllp # mllp version of the message (as a string)Parse an existing HL7 message
raw_input = open( "my_hl7_msg.txt" ).readlines
msg = HL7::Message.new( raw_input )
puts "message type: %s" % msg[:MSH].message_typeSetting :format for element of segment allows you to get hash:
class HL7::Message::Segment::PID < HL7::Message::Segment
...
add_field :patient_name, {:format => HL7::Message::DataTypes.XPN}
end
>> msg[:PID].patient_name
=> {"family_name"=>"Connor", "given_name"=>"John", "middle_name"=>"T", "suffix"=>"", "prefix"=>"", "degree"=>"", "name_type_code"=>"L", "origin"=>"Connor^John^M^^^^L"}
>> msg[:PID].patient_name['origin']
=> "Connor^John^M^^^^L"See the LICENSE file.
