Description

Technical Field

[0001] This utility model relates to the field of gas storage for counterpulsation devices, specifically to a non-circular gas storage tank structure for an external counterpulsation device. Background Technology

[0002] External counterpulsation (ECP) is a therapy that uses non-invasive external pressure on the limbs to relieve and eliminate angina symptoms and improve the hypoxia and ischemia state of vital organs. It primarily uses inflatable bladders wrapped around the limbs and buttocks. During diastole, the bladders are inflated and pressurized, prompting blood from the limb arteries to return to the aorta, significantly increasing diastolic pressure, increasing blood flow to the heart, and reducing cardiac afterload. During systole, the bladders are rapidly deflated, releasing pressure and causing a decrease in systolic pressure in the aorta, minimizing resistance during cardiac ejection and accelerating blood flow to distal organs, thus achieving the counterpulsation effect. External counterpulsation can promote blood circulation, increase blood flow to vital organs such as the heart and brain, thereby helping to improve the supply of nutrients and oxygen to various parts of the body.

[0003] In order to inflate the airbags, the counterpulsation device includes an air tank. Since the counterpulsation device has many airbags, a lot of gas is needed to quickly and fully inflate the airbags. This results in the need for a large air tank to hold the gas. If the air tank is a common cylindrical shape, the volume of the air tank is large, and when placed inside the counterpulsation device, it can easily obstruct the installation of adjacent structures.

[0004] To address the aforementioned issues, the applicant, in patent application number 202411699424.1, disclosed an integrated external counterpulsation mobile device. This design incorporates multiple vertical and multiple horizontal air tanks forming a frame structure. A horizontal air tank is positioned between each pair of adjacent vertical air tanks, with both ends of the horizontal air tank connected to the connected vertical air tanks. This allows the air tanks to serve as the supporting frame for the counterpulsation mobile device's outer shell, replacing the internal support structure of the counterpulsation device, thereby reducing the device's size and weight and facilitating miniaturization.

[0005] However, in the aforementioned mobile counterpulsation machine, the compressor is located inside the structural frame. In actual implementation, it was found that when the length and width of the counterpulsation machine housing are the same, the lower end of the vertical air tank is located between the compressor and the housing. Therefore, the length and width of the compressor need to be smaller to be installed inside the structural frame. However, reducing the size of the compressor will undoubtedly reduce the power of the compressor, resulting in the compressor being unable to provide more gas to the air tank per unit time, which in turn causes a delay in the expansion of the air bladder. Utility Model Content

[0006] The present invention aims to provide an irregularly shaped gas tank structure for an external counterpulsation device, in order to solve the problem that the gas tank can only accommodate a small compressor, resulting in a delay in the inflation of the air bladder.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an irregularly shaped gas storage tank structure for an external counterpulsation device, comprising multiple vertical gas tanks and multiple horizontal gas tanks. The horizontal gas tanks are distributed between two adjacent vertical gas tanks and are interconnected. The multiple vertical gas tanks and multiple horizontal gas tanks together form a structural frame. The multiple vertical tanks are all installed above the compressor. The multiple horizontal gas tanks are divided into a first tank and a second tank. The connection between the first tank and the adjacent vertical gas tank is located at the lower part of the vertical gas tank.

[0008] The beneficial effects of this plan are:

[0009] In this design, the gas tank structure is installed above the compressor. Therefore, the installation of the compressor is no longer limited by the gas tank structure, and a compressor with greater power can be selected based on the size of the outer shell. That is, with the same outer shell size, the compressor size can be larger, thereby providing more gas per unit time when the external counterpulsation device is working, so that the airbag can inflate more quickly and improve the airbag's response efficiency.

[0010] Secondly, because the gas tank structure is located above the compressor, the compressor's heat dissipation is no longer blocked by the gas tank structure. Furthermore, the gas tank structure is relatively independent from the compressor, and there is more space around the gas tank, making it easier for the heat inside the gas tank to dissipate, thereby improving the heat dissipation efficiency of the gas tank structure.

[0011] Finally, with the same height for the outer casing and the compressor, the gas tank structure in this solution does not require installation space for the compressor, so the vertical gas tank can be set to be shorter and wider. That is, the vertical gas tank has a larger diameter and a smaller height, which makes the center of gravity of the structural frame composed of the vertical and horizontal gas tanks lower and less likely to tip over during movement.

[0012] Furthermore, the cross-sectional area of ​​at least one transverse gas tank inner wall is larger than the cross-sectional area of ​​the vertical gas tank.

[0013] The beneficial effects of this solution are: the horizontal gas tank in this solution can better connect adjacent vertical gas tanks, allowing the gas to flow at a greater speed between the vertical and horizontal gas tanks.

[0014] Furthermore, the connection point between the second tank and the adjacent vertical gas tank is located at the top of the vertical gas tank.

[0015] The beneficial effects of this solution are: the staggered connection positions of the first and second tanks with the adjacent vertical gas tanks ensure that there are no dead corners in the vertical gas tanks where gas cannot flow out.

[0016] Furthermore, the side of the first tank facing the outer shell is flat.

[0017] The beneficial effects of this solution are: the planar design allows the first tank to be closer to the outer shell, thereby reducing the gap between the first tank and the outer shell and improving the utilization efficiency of the internal space of the outer shell.

[0018] Furthermore, the top of the first tank is provided with an air outlet.

[0019] The advantage of this design is that the air outlet at the top allows for easier connection with the airbag above.

[0020] Furthermore, at least one of the first tank and the vertical gas tank is provided with an air inlet port.

[0021] The beneficial effect of this solution is that the compressor can more easily introduce gas into the gas tank structure through the nearest port.

[0022] Furthermore, at least one vertical gas tank is provided with a fixing assembly, which includes a fixing plate and at least two support rods. The fixing plate is distributed along the axial direction of the vertical gas tank, and the horizontal cross-section of the fixing plate is L-shaped. The fixing plate includes a first side plate and a second side plate. The first side plate is opposite to the outer shell, and the end of the second side plate is fixed to the vertical gas tank. The support rods are located in the space formed by the first side plate and the second side plate, and all the support rods are fixed at one end to the first side plate and at the other end to the vertical gas tank.

[0023] The beneficial effects of this solution are as follows: the L-shaped fixing plate has greater strength, enabling a better connection between the vertical gas tank and the outer shell, thus securing the vertical gas tank. The support rod further supports the fixing plate, preventing deformation and improving the securing effect on the vertical gas tank, thus preventing displacement.

[0024] Furthermore, a support plate is provided at the end of the first side plate. One end of the support plate is fixed to the first side plate, and the other end is bent toward the side closer to the vertical gas tank and fixed to the vertical gas tank.

[0025] The beneficial effects of this solution are: the support plate can support the end of the fixing plate, thereby further preventing deformation of the fixing plate and improving the fixing effect on the vertical gas tank. Attached Figure Description

[0030] Example

[0031] The implementation examples are basically as follows Figure 1 As shown, an external counterpulsation device with an irregularly shaped gas tank structure includes four vertical gas tanks 1 and four horizontal gas tanks. All the vertical gas tanks 1 and horizontal gas tanks are made of stainless steel and form a structural frame, which is located above the compressor. Specifically, a protective shell is first installed on the compressor, and then the structural frame is installed on the protective shell. The four vertical gas tanks 1 are located at the four corners of the compressor. The bottom of the vertical gas tanks 1 is welded with a mounting plate 11, which is bolted to the top of the protective shell to fix the bottom of the vertical gas tanks 1.

[0032] The vertical gas tank 1 also has a fixing component on the side wall facing the outer casing, combined with... Figure 2 The fixing assembly includes a fixing plate and two support rods 7. The fixing plate is vertically distributed and includes an integrally bent first side plate 2 and a second side plate 22. The first side plate 2 is attached to the inner wall of the outer shell and fixed to the outer shell with bolts. The second side plate 22 is perpendicular to the vertical gas tank 1 and welded to the side wall of the vertical gas tank 1. Each of the two support rods 7 is welded to the vertical gas tank 1 at one end and to the first side plate 2 at the other end to support the first side plate 2. The top of the first side plate 2 is also integrally bent to form a support plate 21. The upper end of the support plate 21 is inclined to the left, and the end of the support plate 21 is welded to the vertical gas tank 1 to prevent the fixing plate from deforming.

[0033] The four horizontal gas tanks are divided into two first tank bodies 3 and two second tank bodies 4. Each horizontal gas tank is fixed and connected to two adjacent vertical gas tanks 1. Specifically, the first tank bodies 3 are used to connect the two front vertical gas tanks 1 and the two rear vertical gas tanks 1. The front and rear side walls of the first tank bodies 3 are flat to reduce the gap with the outer shell and increase the space inside the structural frame. The cross-sectional areas of the two first tank bodies 3 and the right second tank body 4 are all larger than the cross-sectional area of ​​the vertical gas tanks 1. The two second tank bodies 4 are used to connect the two left vertical gas tanks 1 and the two right vertical gas tanks 1, respectively. In this embodiment, the connection points between the two first tank bodies 3 and the vertical gas tanks 1 are located at the lower part of the vertical gas tanks 1, and the connection points between the two second tank bodies 4 and the vertical gas tanks 1 are located at the upper part of the vertical gas tanks 1. The top of the first tank 3 on the front side is provided with multiple air outlet ports 5. The first tank 3 and one of the vertical tanks are provided with air inlet ports 6 on the side away from the outer shell. In actual implementation, the air outlet ports 5 are connected to the airbag of the counterpulsation device through pipes, and the air inlet ports 6 are connected to the air outlet of the compressor. Specifically, the position and number of air outlet ports 5 are determined according to the number and position of the airbags.

[0034] In this embodiment, the stainless steel material and the design of the gas tank, positioned above the compressor, allow heat to dissipate quickly, improving cooling efficiency. Furthermore, the gas tank structure no longer obstructs the installation of the compressor.
