Description

TECHNICAL FIELD

[0001] The utility model relates to counterpulsation device technical field, specifically related to a compact counterpulsation device. BACKGROUND

[0002] Counterpulsation device is a kind of medical equipment for heart auxiliary treatment, mainly used to improve heart function, increase coronary blood flow and improve myocardial oxygen supply.Counterpulsation device usually includes air bag, control system, gas storage tank and connecting pipeline and other key components.The working principle is based on synchronous trigger mechanism, and in diastolic phase, air bag is inflated to compress lower limb blood vessels, force blood to flow upwards, increase the cardiac blood volume;And in systolic phase, air bag deflates to release the pressure on blood vessels, so that blood flows smoothly into the heart.The periodic inflation and deflation process can effectively enhance the pumping function of heart, and is suitable for the treatment of acute myocardial infarction, cardiogenic shock, unstable angina and other cardiovascular diseases.

[0003] In order to ensure that the air pressure of air bag is more smooth, the capacity of gas storage tank is a key factor.Under normal circumstances, the larger the gas storage capacity, the more smooth the air pressure change of single air bag, thereby providing more stable treatment effect.In order to increase the gas storage capacity, larger gas storage tank is usually used, however, increasing the gas storage tank will lead to the increase of the volume of the whole counterpulsation device, occupy more space, affect the portability and use convenience of the device.In order to solve this problem, the applicant developed an extracorporeal counterpulsation multi-container combination device (publication number: CN215566507U;application date: 2021-06-03).The device replaces the existing single gas storage container by combining multiple small gas storage containers, and the multiple small gas storage containers have smaller volume than the single large gas storage container, which can be more flexibly arranged in the bed frame, and fully utilize the limited space.Although the multi-container combination device solves the problem of the increase of the volume of gas storage tank to some extent, it is found in actual application that the gas storage tank of the device still occupies a large space, which limits the further increase of the gas storage capacity. UTILITY MODEL CONTENTS

[0004] The utility model intends to provide a compact counterpulsation device to solve the problem that the gas storage capacity of prior art occupies larger space, which leads to the difficulty of further increasing the gas storage capacity.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0007] Preferably, as an improvement, the left gas storage tank group and the right gas storage tank group are arranged close to the inner wall of the bed body.

[0008] Preferably, as an improvement, the main gas storage tank is communicated with a first gas outlet pipe at both ends, the first gas storage tank is communicated with a gas inlet pipe at the side facing the main gas storage tank, and the first gas outlet pipe is communicated with the gas inlet pipe; the main gas storage tank is further communicated with a second gas outlet pipe, the second gas outlet pipe is communicated with a first electromagnetic valve, and the second gas outlet pipe is communicated with the air bag through the first electromagnetic valve; the second gas storage tank is communicated with a gas outlet pipe at the side facing the middle part of the bed body, the gas outlet pipe is communicated with a second electromagnetic valve, and the gas outlet pipe is communicated with the air bag through the second electromagnetic valve.

[0009] Preferably, as an improvement, the electric control chamber and the gas supply chamber are arranged on both sides of the gas storage chamber respectively, the main gas storage tank is arranged close to the electric control chamber, the bottom outer side of the bed body is provided with a heat dissipation pipe, and the gas supply mechanism is communicated with the main gas storage tank through the heat dissipation pipe.

[0010] Preferably, as an improvement, the electric control chamber is communicated with the gas storage chamber, a heat dissipation port is opened at the bottom of the electric control chamber, a heat dissipation fan is installed at the heat dissipation port, and the heat dissipation fan is arranged at the side of the main gas storage tank.

[0011] Preferably, as an improvement, the first gas storage tank and the second gas storage tank are communicated through a connecting pipe.

[0012] Preferably, as an improvement, a gap is left between the left gas storage tank group and the inner wall of the bed body, and a gap is left between the right gas storage tank group and the inner wall of the bed body.

[0013] Preferably, as an improvement, a fixing frame is fixed at the bottom of the first gas storage tank and the second gas storage tank, the fixing frame is detachably connected with the bed body, and a gap is left between the bottom of the first gas storage tank, the bottom of the second gas storage tank and the bed body.

[0014] Preferably, as an improvement, the volume, shape and size of the first gas storage tank and the second gas storage tank are the same.

[0015] Preferably, as an improvement, an electric control box is arranged in the electric control chamber, and the electric control box is arranged above the heat dissipation fan.

[0016] The principle and beneficial effects of the present scheme are as follows:

[0017] 1. This solution utilizes a main gas storage tank, a left gas storage tank group, and a right gas storage tank group connected together for gas storage. Compared to using only a single large gas storage tank, this method makes better use of the gas storage chamber space. Furthermore, the left and right gas storage tank groups are vertically oriented, further reducing the footprint of the gas storage tanks. Within the same footprint, connecting the first and second gas storage tanks to form a gas storage tank group can further increase the gas storage capacity without increasing the equipment size.

[0018] This solution retains the horizontal main gas storage tank, achieving a balance between a small footprint and large gas storage capacity. If two vertical gas storage tanks were installed in the same location as the main tank, the gas storage capacity would be relatively reduced; conversely, installing two gas storage tank groups would increase the equipment size. Therefore, this solution combines a horizontal main gas storage tank with vertical gas storage tank groups, achieving a significant increase in gas storage capacity within the original volume and space constraints.

[0019] 2. The left and right gas storage tank groups are positioned opposite each other on the inner wall of the bed, with sufficient space left between them for pipeline connections. The outlet pipe of the second gas storage tank faces the central open area, facilitating centralized pipeline connections between the left and right gas storage tank groups for easy connection and management. The first outlet pipe of the main gas storage tank is located at both ends, allowing for easy connection to the left and right gas storage tank groups located on both sides, reducing pipeline length and avoiding problems such as high cost, inconvenient installation, and large space occupation caused by excessive pipeline length.

[0020] 3. This design places the main gas storage tank close to the electrical control room, away from the gas supply room. This allows for sufficient space between the gas supply mechanism and the main gas storage tank to install cooling pipes, effectively dissipating heat from the gas output by the gas supply mechanism before it is introduced into the main gas storage tank. The cooling pipes are located on the outer side of the bottom of the bed, allowing them to contact the ambient air and improving heat dissipation.

[0021] 4. The electrical control room and the gas storage chamber are connected. The cooling fan is located in the electrical control room. When the cooling fan operates, the hot air in both the electrical control room and the gas storage chamber can be drawn out, achieving heat dissipation for both chambers. This eliminates the need for multiple cooling systems, simultaneously cooling both the electrical control room and the gas storage chamber, saving equipment costs. Furthermore, this solution suspends the electrical control box above the cooling fan, allowing the fan to also dissipate heat from the box during operation.

[0022] 5. In this design, the first and second air storage tanks have the same shape, structure, and dimensions, ensuring a balanced and stable internal air pressure. The first and second air storage tanks are connected by a connecting pipe, creating a gap between them. Additionally, gaps are also provided between the first and second air storage tanks and the inner wall and bottom of the bed, increasing their heat dissipation area. When the cooling fan is drawing air, all surfaces of the first and second air storage tanks can dissipate heat, resulting in excellent cooling performance. Similarly, a gap is also provided between the bottom of the main air storage tank and the bottom of the bed, ensuring good heat dissipation for the main air storage tank.

[0023] This solution uses a heat dissipation pipe to cool the gas output from the gas supply mechanism, and a cooling fan to cool the gas storage chamber. In addition, the vertical arrangement of the first and second gas storage tanks ensures good gas cooling effect, thereby improving the patient's treatment comfort.

[0024] In summary, the vertical arrangement of the left and right gas storage tank groups in this scheme not only increases the gas storage capacity without increasing the equipment size and reducing the footprint of the gas storage tanks, but also provides better heat dissipation for the gas storage tanks.

[0029] The following detailed description illustrates the specific implementation method:

[0030] The reference numerals in the accompanying drawings include: bed body 1, electrical control room 2, air storage room 3, air supply room 4, heat dissipation vent 5, electrical control box 6, main air storage tank 7, left air storage tank group 8, right air storage tank group 10, main air inlet pipe 11, first air outlet pipe 12, second air outlet pipe 13, air inlet pipe 14, air supply pipe 16, first air storage tank 17, second air storage tank 18, air outlet pipe 19, fixing frame 20, and heat dissipation pipe 21.

[0031] Example:

[0032] like Figure 1As shown in the figure, a compact counterpulsation device includes a bed body 1, which is internally divided from left to right into an electric control chamber 2, an air storage chamber 3 and a gas supply chamber 4. The electric control chamber 2 and the air storage chamber 3 are communicated, and the air storage chamber 3 and the gas supply chamber 4 are separated by a partition. The bottom of the electric control chamber 2 is provided with a heat dissipation port 5, and a heat dissipation fan (not shown in the figure) is installed at the heat dissipation port 5. An electric control box 6 is installed above the heat dissipation fan.

[0033] In combination Figure 2 And Figure 3 As shown in the figure, a horizontal main air storage tank 7 is installed in the air storage chamber 3. The main air storage tank 7 is arranged on the right side of the heat dissipation fan. Specifically, a fixing frame 20 is welded to the bottom of the main air storage tank 7, and the fixing frame 20 is fixed to the bottom plate of the bed body 1 by screws. The bottom of the main air storage tank 7 is elevated by the fixing frame 20, so that a gap is left between the main air storage tank 7 and the bottom plate of the bed body 1, facilitating heat dissipation.

[0034] A vertical left air storage tank group 8 and a vertical right air storage tank group 10 are installed on the right side of the main air storage tank 7. The left air storage tank group 8 and the right air storage tank group 10 are oppositely arranged. The left air storage tank group 8 and the right air storage tank group 10 are arranged close to the inner wall of the bed body 1 but leave a gap between the left air storage tank group 8 and the right air storage tank group 10 and the inner wall of the bed body 1, so as to facilitate heat dissipation. The left air storage tank group 8 and the right air storage tank group 10 each include two communicated first air storage tanks 17 and second air storage tanks 18. The first air storage tanks 17 and the second air storage tanks 18 are communicated by connecting pipes. The first air storage tanks 17 and the second air storage tanks 18 are also welded with fixing frames 20 at the bottom. The fixing frames 20 are fixed to the bottom plate of the bed body 1 by screws. The bottom of the first air storage tank 17 and the bottom of the second air storage tank 18 are elevated by the fixing frames 20, so that gaps are left between the bottom of the first air storage tank 17 and the bed body 1 and between the bottom of the second air storage tank 18 and the bed body 1, facilitating heat dissipation. The first air storage tanks 17 and the second air storage tanks 18 are identical in shape, structure and size, so as to ensure that the air pressure in the tanks is balanced and stable.

[0035] A gas supply mechanism (not shown in the figure) is installed in the gas supply chamber 4. In this embodiment, the gas supply mechanism is a compressor. In combination Figure 4As shown, the bottom outer side of the bed body 1 is provided with a heat dissipation pipe 21, the heat dissipation pipe 21 is arranged in an S shape, the air supply pipe 16 of the air supply mechanism is communicated with the heat dissipation pipe 21 after passing through the bottom plate of the bed body 1, and the air supply pipe 16 is communicated with the main air inlet pipe 11 of the main gas storage tank 7 through the heat dissipation pipe 21, so that the compressed air output by the air supply mechanism is cooled through the heat dissipation pipe 21 and then enters the main gas storage tank 7. The first air outlet pipe 12 is communicated with the two ends of the main gas storage tank 7, and the two first gas storage tanks 17 are communicated with the air inlet pipes 14 on the side facing the main gas storage tank 7. The two first air outlet pipes 12 are respectively communicated with the two air inlet pipes 14. The second air outlet pipe 13 is further communicated with the main gas storage tank 7, and the second air outlet pipe 13 is used to communicate with the air bag on the bed body 1. Specifically, the second air outlet pipe 13 is communicated with a first electromagnetic valve (not shown in the figure), and the second air outlet pipe 13 is communicated with the air bag through the first electromagnetic valve. The two second gas storage tanks 18 are communicated with the air outlet pipes 19 on the side facing the middle part of the bed body 1, and the two air outlet pipes 19 are communicated with a second electromagnetic valve (not shown in the figure) through a three-way joint, and then the second electromagnetic valve is communicated with the air bag.

[0036] In actual use, the compressed air enters the heat dissipation pipe 21 through the air supply mechanism, is exchanged with air through the heat dissipation pipe 21, and then enters the main gas storage tank 7, and then enters the left gas storage tank group 8 and the right gas storage tank group 10, and finally enters the air bag through the second air outlet pipe 13 and the air outlet pipe 19. The first electromagnetic valve and the second electromagnetic valve are used to control the on-off of the compressed air. The present scheme uses the main gas storage tank 7, the left gas storage tank group 8 and the right gas storage tank group 10 to communicate to store gas, which can better utilize the space of the gas storage chamber 3 compared with using only one large gas storage tank. On this basis, the left gas storage tank group 8 and the right gas storage tank group 10 use vertical gas storage tanks, which can further reduce the floor space occupied by the gas storage tanks; and the left gas storage tank group 8 and the right gas storage tank group 10 are arranged along the inner wall of the bed body 1, leaving a pipeline connection space in the middle, which is convenient for connecting and managing the pipeline.

[0037] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should be regarded as the protection scope of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
