Specific embodiment
Embodiment one: the preparation of external ventral aorta far-end blocking vessel of the present invention
External ventral aorta far-end blocking vessel of the present invention, as shown in Figure 1, comprising: the bedplate 1 of level, when
During use, described bedplate is arranged on below the lower back of the human body of horizontal position；Fixing pillar 3, is vertically fixed on bedplate
On the fixing point 2 of 1 side；Portable stanchion 9, its bottom equipped with abdominal part pressure head 10, for contacting and oppressing the people in horizontal position
The abdominal part of body；Arching pressure arm 6, its one end is connected with described fixing pillar 3 by the first joint 4 adjustable ground, the other end
It is connected with described portable stanchion 9 by second joint 7 adjustable ground.
The operation principle of external ventral aorta far-end blocking vessel of the present invention is: when patient lies supine in operating-table or
When cardiopulmonary resuscitation (cpr) is carried out on sick bed, the first joint 4 on fixing pillar 3 is opened, with umbilicuss for index point by level
Bedplate 1 to be placed in below patient's lower back with patient's major axis vertical direction.Then, by portable stanchion 9, pressure head 10 is put
Put on the abdominal part of the human body of horizontal position, then by adjusting the on the first joint 4 and portable stanchion 9 on fixing pillar 3
Two joints 8, and adjust radian and the length of arching pressure arm, size, position and the effect side of ventral aorta pressure can be directed to
To the pressure head 10 on corresponding adjustment abdominal part at the position of body surface, make abdominal part pressure head corresponding with human body ventral aorta in vitro
Skin surface reach optimum contact, reach the purpose of external ventral aorta far-end temporary interruption.Therefore, it can effectively from body
Outer ventral aorta Distal blood flow temporary interruption is increased distal aorta resistance, improve alteration of left ventricular afterload, thus effectively increasing
Plus coronary perfusion pressure (cpp), to improve the vitals such as the heart, brain, kidney and to continue blood perfusion, so that improve sudden cardiac arrest suffering from
Person's rescue recovery success rate.
Concrete when manufacturing, as needed the shape of bedplate can be made following shape: rectangle, square, rhombus,
Polygon, circle, ellipse etc..
For the ease of manipulating and adjusting external ventral aorta far-end blocking vessel of the present invention, as shown in figure 1, permissible
Equipped with the first joint knob 5 it is also possible to equipped with second joint knob 7 on second joint 8 on the first joint 4.
Implement operational approach: in human body horizontal position (when for example, prostration is on ground or bed surface), by bedplate (1) and body
The vertical direction of long axis of body is inserted into prostration between the human waist and back of ground (bed surface) and ground (or bed surface).Unclamp first
Individual joint knob 5, abdominal part pressure head 10 be aligned body surface symbol (for example, using human body umbilicuss as body surface symbol), down force pressure arm 6,
Abdominal part pressure head 10 is pressurizeed to lumbar vertebra direction, such as adjustable second joint 8 of abdominal part pressure head contact umbilicuss position slightly deviation will
Direction and location-appropriate adjustment, keep portable stanchion (9) vertical with human coronary face, to ensure for ventral aorta far-end to be pressed in waist
On vertebra vertebral body, reach the purpose of extracorporeal blocking ventral aorta Distal blood flow.
Due to body fat or the individual variation become thin, when using external ventral aorta of the present invention remote overweight people
During the blocking vessel of end, two joints can be opened simultaneously, make " opening " foot between bedplate and portable stanchion and abdominal part pressure head
Enough big, it is easy to quick and precisely be placed into position when device uses.
Embodiment two: the application test experiments of external ventral aorta far-end blocking vessel of the present invention
Experiment material: 6 healthy adult experimental dog, provided by Hospital of Southern Medical University Experimental Animal Center, female
Hero is regardless of, body weight (13.7 ± 2.3) kg.
Examination on experimental operation is as follows: animal pre-operative anxiety 12 h, weighs, and through forelimb superficial intravenous infusion, injects pentobarbital
Sodium (30 mg/kg) is anaesthetized.After anesthesia success, tracheal intubation is to maintain respiratory passage unblocked.Animal dog is lain on the back and is fixed on operating-table
On, vascular puncture puts pipe portion position shaving, Thoracic Limb Arteries puncture and intubation dynamic monitoring pressure of the radial artery, and foreleg vein puncture and intubation is dynamic
Monitoring center's venous pressure.Hind leg artery and vein puncture and intubation dynamic monitoring femoral artery and femoral vein pressure.After stable etc. animal state,
The indexs such as synchronous recording forward and backward limb arteriotony, central venous pressure, femoral vein pressure.Monitor is that Hewlett-Packard 1 186a type is many
Function physiological monitor, connects forward and backward limb monitoring passage respectively；The every physical signs of monitoring.
Above-mentioned preparation finishes dog and lies on the back when being fixed on operating-table, will apparatus of the present invention bedplate 1 long with dog body
The vertical direction of axle is placed in test dog lower back.Unclamp first joint knob 5, abdominal part pressure head 10 is directed at dog midline abdominal abdomen master
The most notable position (as body surface symbol) of tremulous pulse distal section, arteriopalmuses, down force pressure arm 6, by abdominal part pressure head 10 to lumbar vertebra direction
Pressurization, such as abdominal part pressure head contact abdominal region slightly deviation can adjust second joint 8 and adjust direction and location-appropriate, keeps
Portable stanchion 9 is perpendicular with operation table surface, to ensure dog ventral aorta distal section is pressed on lumbar vertebra, by ventral aorta to waist
Vertebral body extrudes and disappears to bilateral femoral arterial pollex, now blocks successfully for abdominal aorta flow.And by first joint knob 5 He
Second joint knob 7 is tightened, and reaches the purpose of extracorporeal blocking ventral aorta Distal blood flow.Xining 30 minutes.
Experimental result is as follows:
1st, live body test after being anesthetized: external Abdominal aortic crossclamping forward and backward coronary perfusion pressure (cpp) average by
99.84 increasing to 107.54mmhg.
2nd, when smother play causes cardiac arrest after being anesthetized: during free-hand chest compression cardio-pulmonary resuscitation, external ventral aorta resistance
Disconnected forward and backward coronary perfusion pressure (cpp) average increases to 40.71mmhg by 22.68.
