Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of Portable magnetic sensing locating guide device and its method.
Background technology
In medical field, massive haemorrhage is common clinical acute disease in Acute Spontaneous massive haemorrhage or operation, and the state of an illness is endangered
Anxious, the moment can lead to patient's haemorrhagic shock and threat to life, such as spitting of blood, spitting blood, have blood in stool, hematuria, severe postpartum hemorrhage, art
In with post-operative hemorrhage volume, wound massive haemorrhage etc.;Using artery or aorta after balloon bloodstream blocking art or percutaneous transcatheter closure, can be carved with
Blocking blood flow is imitated, thoroughly stops blooding, is most timely, effective life saving measure.Balloon occlusion or closure refer under local anaesthesia, percutaneously
Through peripheral blood vessel(Femoral artery, arteria brachialis etc.)It punctures, is introduced into aorta and arterial branch at different levels and carry expansible comply with
Property sacculus or non-compliance foley's tube, in bleeding internal organs Nutrient arteries or Nutrient arteries open area or its nearly heart section
Main artery balloon occlusion blood flow achievees the purpose that stop blooding at once.
Existing artery or aortectasia foley's tube blocking blood flow, operation must x-ray real-time fluoroscopic shadows in vitro
Picture(Digital subtraction angiography-DSA)Guiding under complete, external X-ray examination has the function of accurate Anatomical orientation in real time, can
With panorama, in real time operation and operational circumstances of the monitoring foley's tube in body cavities, it is widely used by clinic, but x-ray is real
When have an X-rayed digitized video(DSA)Guiding is lower to be operated, and needs expensive DSA equipment and special intervention operating room or high standard

Spontaneous massive haemorrhage and operation massive haemorrhage can be not only happened in hospital, this convenient for being instantly available the place of rescue, more
More conventional spontaneous massive haemorrhage, be in the case where having no sign, be happened at non-medically, in daily life occasion, such as
Occur suddenly in the daily lifes scene such as community, family, station, square, road, tourist site, need to take immediate measure, take action
Arteries and veins or aorta after balloon expansion blocking blood flow treatment, in bleeding internal organs Nutrient arteries, the aorta of Nutrient arteries open area
Or blocking blood flow in proximal part aorta, reach the therapeutic effect stopped blooding immediately.All do not have DSA on almost all of ambulance
Equipment, it is difficult to which guiding in real time foley's tube percutaneously punctures the process of merging target area through peripheral blood vessel, can not be timely and accurate
Carry out artery or aorta after balloon expansion blocking blood flow.When many battlefield first aids, burst natural calamity, rescue scene connects
Basic supply of electric power does not all have, and unlikely sets up installation DSA iconography guiding equipment;In addition to this, even if in hospital
Face, also certain patients, such as pregnant and lying-in women, child etc. consider that the foley's tube of uncomfortable DSA guiding is placed in for radiation safety
Method, for example, x-ray sensitive group or sensitive internal organs position person intubation, infant, children, standby pregnant person, pregnancy person, reproduction body of gland
(Male testical, women ovary), high function body of gland(Adrenal gland, thymus gland, thyroid gland, pituitary etc.), carry out the x-rays such as conduit insertion
The interventional radiology operation of image Hygienic monitoring on hands of childhood, can be by the x-ray radiation of doses, and such crowd and privileged sites are by one
Determine the x-ray radiation of dosage, it is possible to produce permanent body harm, so cannot be grasped with external x-ray real-time fluoroscopic image
It operates.
