AFAIS the One2Many definition should be:
z_medical_history = fields.One2Many(
'gnuhealth.z_medical_history',
'patient', 'Patient Medical History', help='Enter the Patient
Medical History'
' for the patient.')
Note the second parameter must be the name of the Many2One field of
the related model.

If you need to access the information of z_medial_history from another
model either you link it directly or you create a Function field. I
guess the latter is what you're looking for. So you need something
like this:
z_medical_history =
fields.Function(fields.Many2Many('gnuhealth.z_medical_history',
None, None, 'Historial Medico del Paciente'), 'get_z_medial_history')
