Description

Technical Field

[0001] The utility model relates to the technical field of extracorporeal antipulsation devices, in particular to a combined gas storage tank. Background Art

[0002] EECP is a method of non-invasively applying external pressure to the lower body to alleviate and eliminate angina symptoms and improve hypoxia-ischemia in vital organs. It is also a medical device used to prevent and treat cardiovascular and cerebrovascular diseases. It involves inflating and pressurizing balloons wrapped around the limbs and buttocks during diastole, driving blood from the limb arteries back into the aorta, significantly increasing diastolic pressure, increasing blood flow to the heart, and reducing cardiac afterload. During systole, the balloons are rapidly deflated, relieving pressure and causing a decrease in systolic pressure in the aorta. This minimizes resistance during the ejection phase and accelerates blood flow to the distal end, achieving the EECP effect.

[0012] Preferably, there are two groups of horizontal gas tanks, each group has two horizontal gas tanks, and the two groups of horizontal gas tanks are respectively located on two opposite surfaces of the rectangular frame, wherein both ends of a gas storage tank of one group of horizontal gas tanks are connected to the upper part of the vertical gas tank, and both ends of the other group of horizontal gas tanks are connected to different height positions of the vertical gas tank.

[0013] Preferably, the radii of the vertical gas tank and the horizontal gas tank are equal, and the heights of the vertical gas tanks are consistent. This has the advantage that the resulting multi-prism frame structure has better consistency and can be well connected by welding or other means.

[0025] Example 1 Figure 1 and Figure 2 As shown:

[0026] A combined gas storage tank includes multiple vertical gas tanks 1 and multiple horizontal gas tanks 2, wherein the multiple vertical gas tanks 1 are parallel to each other, each horizontal gas tank 2 is arranged between two adjacent vertical gas tanks 1, and both ends of the horizontal gas tank 2 are connected to the corresponding vertical gas tank 1; the multiple vertical gas tanks 1 and the multiple horizontal gas tanks 2 form a polygonal column frame.

[0027] During specific implementation, in this scheme, there are four vertical gas tanks 2, and there are also four horizontal gas tanks 1. The horizontal gas tanks 2 are connected one by one between adjacent vertical gas tanks 1. The vertical gas tanks 1 and the horizontal gas tanks 2 form a rectangular frame, in which the vertical gas tanks 1 are specifically side ribs; the horizontal gas tanks 2 are all located in the middle and upper part of the vertical gas tanks 1. The advantage of this is that the horizontal gas tanks are set in the middle and upper part of the vertical gas tanks. During maintenance, it is possible to reach into the interior through the frames of the horizontal gas tanks and the vertical gas tanks for maintenance, and the operating space is larger.

[0028] During implementation, in order to make the formed rectangular frame structure more consistent and facilitate welding, the radii of the vertical gas tank 1 and the horizontal gas tank 2 are equal, and the height of the vertical gas tank 1 is consistent.

[0029] During implementation, a mounting ear 3 is provided at the bottom of the vertical gas tank 1. The end of the mounting ear 3 is folded and perpendicular to the vertical gas tank 1, and a mounting hole is opened at the end of the mounting ear 3; a mounting plate 4 is provided at the bottom of the vertical gas tank 1, and the vertical gas tank 1 is fixedly connected to the mounting plate 4 through the mounting hole of the mounting ear 3; through the coordinated arrangement of the mounting plate and the mounting ear, it is convenient to install the vertical gas tank on the same plane to ensure its stability. The arrangement of the mounting plate also facilitates the overall movement and installation of the vertical gas tank.

[0030] Working principle:

[0031] The gas storage tank of this solution is composed of a vertical gas tank 1 and a horizontal gas tank 2 that are interconnected. The horizontal gas tank 2 connects multiple vertical gas tanks 1 one by one to form a large gas storage tank with a larger gas capacity. Among them, the horizontal gas tank 2 and the vertical gas tank 1 generation steel frame are used as structural support to reduce the size and weight of the equipment, increase the strength, and the space inside the frame can accommodate other components, thereby increasing the integration level and being more conducive to miniaturization of the external counterpulsation device.

[0032] Example 2:

[0033] like Figure 3 , different from Example 1, in this embodiment, there are two groups of horizontal gas tanks 2, each group of horizontal gas tanks 2 has two, and the two groups of horizontal gas tanks 2 are respectively located on two opposite surfaces of the rectangular frame, and one gas storage tank of one group of horizontal gas tanks 2 is connected at both ends to the upper part of the vertical gas tank 1 to leave enough operating space for maintenance, and the other two ends of the horizontal gas tanks 2 are connected to different height positions of the vertical gas tank 1, where the different heights include being connected to the upper and lower ends of the vertical gas tank 1, both at the lower part of the vertical gas tank 1 or both at the upper part of the vertical gas tank; the horizontal gas tanks 2 at different connection positions have different lengths, different gas capacities, and different strength specifications after connection, which can be selected according to lightweight requirements or gas capacity requirements, and have a wider range of applications.

[0034] Example 3:

[0035] like Figure 4 , this embodiment is different from Embodiments 1 and 2 in that, in this embodiment, a connecting portion 5 is provided at one end or both ends of the vertical gas tank 1. In this embodiment, the connecting portion 5 can be integrally formed with the end of the vertical gas tank 1 or welded to the end of the vertical gas tank 1; in this embodiment, the connecting portion 5 is a hollow tube, the inner wall of which is welded or integrally formed with the outer wall of the vertical gas tank 1. When two vertical gas tanks 1 are spliced, only welding is required to form vertical gas tanks 1 of different specifications. The advantage of this is that only one specification of vertical gas tanks needs to be produced, and different specification requirements can be met by splicing, which has a wider range of applications and lower costs.
