Detailed Description
In the following description, numerous technical details are set forth in order to provide a better understanding of the present application. However, it will be understood by those skilled in the art that the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The utility model discloses a first embodiment relates to a by aorta counterpulsation device. Fig. 1 is a schematic structural diagram of a periaortic counterpulsation apparatus according to the present embodiment when a balloon is inflated.
Specifically, as shown in fig. 1, the periaortic counterpulsation device comprises an air bag, an air tube, an air pump, a control mechanism 15 and an electrocardio sensor 16, wherein the air pump is an electric air pump, reference numeral 3 in the figure denotes a human heart, and reference numeral 5 denotes a descending aorta. The air bag is positioned at the outer side of an ascending aorta 4 in a thoracic cavity 1 of a human body enclosed by muscle tissues 2 of the human body and is contacted with the outer wall of the aorta, the air pump 11 is positioned outside the human body, the air pipe is respectively connected with the air bag and the air pump, and the control mechanism 15 is respectively and electrically connected with the air pump and the electrocardio sensor 16 through a cable 17.
The air bags comprise a first air bag 6 and a second air bag 7, as shown in fig. 3 to 5, the first air bag 6 and the second air bag 7 are both composed of air bag hard membranes 18 and air bag soft membranes 19, the first air bag 6 and the second air bag 7 are respectively and symmetrically distributed on two sides of the aorta 4, and the contact surfaces of the first air bag 6 and the second air bag 7 and the outer wall of the aorta 4 are oval. The trachea includes a first 8, a second 9 and a main 10 trachea. First trachea 8 is connected with first gasbag 6, and second trachea 9 is connected with second gasbag 7, and main tracheal first end is connected with first trachea 8 and second trachea 9, and main tracheal second end is connected with the air pump.
The electric air pump comprises an air chamber 11, an air plug 12, a push rod 13 and a driving mechanism 14, wherein the first end of the push rod 13 is connected with the air plug 12, and the second end of the push rod 13 is connected with the driving mechanism 14.
In this embodiment, the elliptical shape of the contact surface is more preferable for attaching the balloon to the outer wall of the aorta. After the control mechanism and the electrocardio sensor are added into the aorta side counterpulsation device, the control structure can compress the aorta vessel wall at a proper time phase with rhythm synchronous with heart rate by receiving the electrocardio control electric air pump transmitted by the electrocardio sensor, thereby effectively improving the left heart output in an external connection mode and reducing the heart load.
Furthermore, it is understood that in other embodiments of the present invention, the contact surface may have other shapes, such as circular, rectangular, etc. The air pump may also be non-electric, e.g. a manual air pump, to be used in emergency situations where there is a power failure.
Because the hardness of the part of the air bag contacted with the outer wall of the aorta is smaller, the air bag is beneficial to the joint with the wall of the aorta, the aorta is compressed softly, and the hardness of the part of the air bag not contacted with the outer wall of the aorta is larger, and the pressure can be effectively generated on the outer wall of the aorta. Therefore, the hardness of the portion of the balloon in contact with the outer wall of the aorta is lower than the hardness of the portion of the balloon not in contact with the outer wall of the aorta. Namely, the first air bag 6 and the second air bag 7 are both composed of an air bag hard film 18 and an air bag soft film 19.
The air bag positioned outside the aorta of the human body can compress and expand the wall of the aorta vessel in the process of inflating or inhaling the air pump, so that the left heart output is effectively adjusted and improved in an external mode, and the heart load is reduced. For example, in the application of the periaortic counterpulsation device of the present invention, the electrocardiograph sensor can be worn on the wrist or chest to transmit the electrocardiograph signals to the control mechanism 15, the control mechanism processes the electrocardiograph signals and then sends signals to the driving mechanism 14, and the driving mechanism 14 controls the motion frequency of the air plug, so that the deploying and retracting frequency of the air bag soft membrane is consistent with the electrocardiograph frequency. When the air plug 12 is pushed forwards, the air plug 12 compresses air into the two air bags 6 and 7 through the main air pipe 10 and the two branch air pipes 8 and 9, so that air bag soft membranes 19 of the two air bags expand outwards to compress the aorta 4, and the blood supply pressure is improved; when the air plug is stretched backwards, the air in the two air bags is pumped out, and the soft membranes of the air bags shrink inwards, so that the blood pressure of the aorta 4 is restored.
The second embodiment of the utility model relates to a beside-aorta counterpulsation device. The second embodiment is an improvement over the first embodiment in that the balloon is annular and surrounds the aorta 4. The air bag surrounding the outer side of the aorta 4 can more effectively press the aorta in an inflated and deflated state, thereby effectively regulating the blood pressure supplied to the aorta.
