Detailed description of the invention
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, described bedplate is arranged on below the lower back of the human body of horizontal position when deployed; Anchor post 3, is vertically fixed on the fixing point 2 of the side of bedplate 1; Portable stanchion 9, is equipped with abdominal part pressure head 10 bottom it, for contacting and oppress the abdominal part of the human body at horizontal position; Arching pressure arm 6, its one end is connected with described anchor post 3 by the first joint 4 adjustable ground, and the other end 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 carries out cardiopulmonary resuscitation (CPR) on operating-table or sick bed, the first joint 4 on anchor post 3 is opened, with umbilicus be index point by the bedplate 1 of level to be placed in below patient's lower back with patient's long axis normal direction.Then, on the abdominal part by portable stanchion 9, pressure head 10 being placed on the human body of horizontal position, again by regulating the first joint 4 on anchor post 3 and the second joint 8 on portable stanchion 9, and regulate radian and the length of arching pressure arm, can for the pressure head 10 on the corresponding adjustment abdominal part of the size of ventral aorta pressure, position and action direction at the position of body surface, make abdominal part pressure head skin surface corresponding with human body ventral aorta in vitro reach optimum contact, reach the object of external ventral aorta far-end temporary interruption.Therefore; can effectively from external by ventral aorta Distal blood flow temporary interruption; increase distal aorta resistance; improve alteration of left ventricular afterload; thus effectively increase coronary perfusion pressure (CPP); improve the vitals such as the heart, brain, kidney and continue blood perfusion, so that improve sudden cardiac arrest patient rescue recovery success rate.
During concrete manufacture, as required, the shape of bedplate can be made following shape: rectangle, square, rhombus, polygon, circle, ellipse etc.
For the ease of handling and regulating external ventral aorta far-end blocking vessel of the present invention, as shown in Figure 1, on the first joint 4, first joint knob 5 can be housed, also on second joint 8, second joint knob 7 can be housed.
Implementation and operation method: (when human body horizontal position such as, put down and crouch when ground or bed surface), direction vertical with cephalocaudal axis for bedplate (1) is inserted into flat crouching between the human waist and back and ground (or bed surface) of ground (bed surface).Unclamp first joint knob 5, abdominal part pressure head 10 aims at body surface symbol (such as, using human body umbilicus as body surface symbol), down force pressure arm 6, by abdominal part pressure head 10 to the pressurization of lumbar vertebra direction, as abdominal part pressure head contact umbilicus position by direction and location-appropriate adjustment, keeps portable stanchion (9) vertical with human coronary face in deviation adjustable second joint 8 slightly, to ensure ventral aorta far-end to be pressed on lumbar vertebra, reach the object of extracorporeal blocking ventral aorta Distal blood flow.
Due to body fat or the individual variation of becoming thin, when using external ventral aorta far-end blocking vessel of the present invention to overweight people, two joints can be opened simultaneously, make " opening " between bedplate and portable stanchion and abdominal part pressure head enough large, be convenient to quick and precisely be placed into position when device uses.
Embodiment two: the application testing experiment 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, male and female are regardless of, body weight (13.7 ± 2.3) kg.
Examination on experimental operation is as follows: animal pre-operative anxiety 12 h, weighs, through forelimb superficial intravenous infusion, and injection pentobarbital sodium (30 mg/kg) anesthesia.Anaesthetize successfully, tracheal intubation is unobstructed with Hold up voltage road.Being lain on the back by animal dog is fixed on operating-table, and vascular puncture is put pipe position and shaved hair, Thoracic Limb Arteries puncture and intubation dynamic monitoring pressure of the radial artery, foreleg vein puncture and intubation dynamic monitoring central venous pressure.Hind leg artery and vein puncture and intubation dynamic monitoring femoral artery and femoral vein pressure.After in stable condition Deng animal, the indexs such as the forward and backward limb arteriotony of synchronous recording, central venous pressure, femoral vein pressure.Monitor is the multi-functional physiological monitor of Hewlett-Packard 1 186A type, connects forward and backward limb monitoring channel respectively; Monitor every physical signs.
When the complete dog of above-mentioned preparation lies on the back and is fixed on operating-table, direction vertical with dog cephalocaudal axis for the bedplate 1 of apparatus of the present invention is placed in and tests dog lower back.Unclamp first joint knob 5, abdominal part pressure head 10 aims at dog midline abdominal ventral aorta section far away, the most remarkable position of arteriopalmus (as body surface symbol), down force pressure arm 6, abdominal part pressure head 10 is pressurizeed to lumbar vertebra direction, as direction and location-appropriate adjust in deviation adjustable second joint 8 by abdominal part pressure head contact abdominal region slightly, keep portable stanchion 9 and operation table surface perpendicular, to ensure section far away for dog ventral aorta to be pressed on lumbar vertebra, ventral aorta is squeezed to bilateral femoral arterial pollex to lumbar vertebral body disappear, now for abdominal aorta flow blocks successfully.And first joint knob 5 and second joint knob 7 are tightened, reach the object of extracorporeal blocking ventral aorta Distal blood flow.Resistance break time≤30 minutes.
Experimental result is as follows:
1, after being anesthetized live body test: the forward and backward coronary perfusion pressure of external Abdominal aortic crossclamping (CPP) average is increased to 107.54mmHg by 99.84.
2, when smother play causes cardiac arrest after being anesthetized: during free-hand chest compression cardio-pulmonary resuscitation, the forward and backward coronary perfusion pressure of external Abdominal aortic crossclamping (CPP) average is increased to 40.71mmHg by 22.68.
