Description

Technical Field

[0001] This utility model relates to the field of external counterpulsation device technology, specifically to an integrated external counterpulsation mobile machine. Background Technology

[0002] External counterpulsation (ECP) is a non-invasive method of applying pressure to the lower body to relieve and eliminate angina symptoms and improve the hypoxia and ischemia of vital organs. It is also a medical device used to prevent and treat cardiovascular and cerebrovascular diseases. It works by inflating balloons wrapped around the limbs and buttocks. During diastole, the balloons are inflated and pressurized, causing blood to flow back from the limb arteries to the aorta, significantly increasing diastolic pressure, increasing blood flow to the heart, and reducing cardiac afterload. During systole, the balloons 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 sites, thus achieving the counterpulsation effect.

[0003] Utility model patent application number CN201710325563.1 discloses a mobile external counterpulsation device, which includes an isolation box, a working air circuit system, a cooling air circuit system, and electrical components, all of which are located within the isolation box. The working air circuit system includes an air filter, a compressor, a radiator, and an air tank, which are connected in series via air pipes. The compressor and radiator are installed in the lower isolation box, and the air tank is installed in the upper isolation box. Its advantage is that it can effectively reduce the floor space and ensure heat dissipation while reducing the volume. However, in this device, the air tank needs to be placed separately and separated from other components, resulting in low space utilization. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by proposing an integrated external counterpulsation mobile device. By designing the outer shell structure and internal frame, sufficient installation space is provided for internal components, greatly improving the integration of the external counterpulsation mobile device and reducing its space occupation.

[0006] II. Specific Technical Solutions

[0007] An integrated external counterpulsation mobile device includes a housing, a structural frame disposed within the housing, and a gas supply system. The housing comprises a lower housing and an upper housing, with the upper housing covering the perimeter of the structural frame. The bottom of the structural frame is fixedly connected to the upper side of the lower housing. The structural frame includes multiple vertical gas cylinders and multiple horizontal gas cylinders, with a horizontal gas cylinder positioned between each pair of adjacent vertical gas cylinders. The two ends of each horizontal gas cylinder are connected to the connected vertical gas cylinders. The gas supply system includes a compressor and a connecting gas path, wherein the connecting gas path includes a connection for the compressor and the structural frame, and both the compressor and the connecting gas path are disposed inside the structural frame. Casters are also provided at the bottom of the lower housing, and handrails are provided at the top of the upper housing.

[0008] Implementation principle and working principle:

[0009] Unlike existing technologies, where gas tanks are separate in counterpulsation devices, this solution connects vertical and horizontal gas tanks to form a support frame for the integrated mobile external counterpulsation machine. This replaces the internal support structure of the counterpulsation device, reducing its size and weight. Furthermore, the interconnectedness of multiple gas tanks ensures sufficient gas storage capacity and eliminates the need for multiple inlets and outlets, simplifying the structure. The compressor and main components of the gas supply system are located within the structural frame. This design offers higher integration and facilitates miniaturization compared to existing separate gas tank setups. Maintenance is convenient; only the upper casing or one side needs to be disassembled for access through the structural frame. The inclusion of casters and handrails enhances the ease of movement and mobility of the external counterpulsation machine.

[0010] Preferably, the structural frame is a cuboid frame, and there are four vertical gas tanks forming the four side ribs of the cuboid frame. The bottom of each vertical gas tank is fixedly installed on the upper side of the lower shell. There are at least two sets of horizontal gas tanks, and the two ends of each set of horizontal gas tanks are connected to the adjacent vertical gas tanks. Each set of horizontal gas tanks in the cuboid frame has two columns, located on the upper side of an opposite face of the cuboid frame. The advantages of this preferred design are that setting the structural frame as a cuboid frame is more conducive to the assembly of the upper and lower shells, and the structure is simple. Setting one set of horizontal gas tanks on the upper side of the cuboid frame leaves enough open space, which provides sufficient operating space for maintenance, making it simple and convenient.

[0011] Preferably, a first mounting plate is provided on the upper part of the structural frame, and the two ends of the first mounting plate are respectively connected to the upper parts of two adjacent vertical gas tanks. Multiple joints are provided on the first mounting plate, including air inlet joints and air outlet joints. The beneficial effect of this preferred embodiment is that by setting the first mounting plate on the upper part of the adjacent vertical gas tanks, the multiple joints on it have a certain height, which facilitates the connection of the joints for air outlet and air inlet to ensure the smooth operation of the external counterpulsation.

[0012] Preferably, the compressor is fixedly mounted on the upper part of the lower housing, and a shock-absorbing pad is provided between the compressor and the lower housing. The connecting air path includes an air injection pipe, the two ends of which are respectively connected to the air outlet of the compressor and the air inlet of the structural frame. The air inlet of the compressor is equipped with a silencer box. The connecting air path includes an air outlet pipe and an air exhaust pipe. One end of the air outlet pipe is connected to the air outlet of the structural frame, and the other end of the air outlet pipe is connected to the air inlet connector. An air inlet solenoid valve is also provided on the air outlet pipe. One end of the air exhaust pipe is connected to the air exhaust connector, and the other end of the air exhaust pipe is connected to the silencer box. An air exhaust valve is also connected to the air exhaust pipe. The preferred embodiment features a solenoid valve. The shock-absorbing pad between the compressor and the lower housing helps reduce vibration and noise during compressor operation. The compressor inlet silencer further reduces noise. The structural frame consists of multiple interconnected gas tanks. The compressed gas is discharged via the outlet pipe for counter-pulsation. The exhaust speed and volume are controlled by the intake solenoid valve. During counter-pulsation, the gas used for counter-pulsation is discharged. The connected silencer effectively reduces exhaust noise, improving quietness and comfort during counter-pulsation.

[0013] Preferably, the upper shell includes two side plates, which are symmetrically arranged on both sides of the structural frame. A grid connecting plate is provided on one side of each side plate, and the two ends of the grid connecting plate are respectively connected to the corresponding side plate. A rear cover is provided on the other side of each side plate, and the two ends of the rear cover are respectively connected to the two side plates. The beneficial effect of this preferred embodiment is that the grid connecting plate can not only serve as a connection but also facilitate airflow exchange with the outside, which is convenient for heat dissipation and air intake. The side plates, rear cover and grid connecting plate constitute most of the upper shell, which can be directly fitted onto the frame during assembly, effectively reducing the assembly process and difficulty.

[0014] Preferably, a sliding groove is provided on both side plates, the sliding groove being located on the side where the grid connecting plate is located; the upper housing also includes an upper cover plate, the upper cover plate being an L-shaped cover plate, one end of the L-shaped cover plate being slidably connected in the sliding groove, and the other two sides of the L-shaped cover plate being connected to the top of the side plates respectively; the beneficial effect of this preferred embodiment is that, in this solution, the sliding groove provided in front of the side plates allows the L-shaped cover plate to be directly inserted into the sliding groove during assembly, and then the other side of the L-shaped cover plate to overlap with the top of the side plate, effectively reducing the assembly difficulty and workload, and also reducing the amount of screws or clips used, making it simple and convenient.

[0015] Preferably, a second mounting plate is provided between a group of horizontal gas tanks located at the upper end of the vertical gas tank. A support tube is provided on the upper part of the second mounting plate, the support tube passes through the upper cover plate, and a locking nut is provided on the support tube. The bottom of the locking nut abuts against the upper part of the upper cover plate. A cooling fan is provided at the lower part of the second mounting plate. The beneficial effect of this preferred embodiment is that, since the upper cover plate may still be loose between itself and the side plates after installation, it is necessary to fix the upper cover plate. The upper cover plate is clamped between the support tube and the second mounting plate by the cooperation of the support tube and the locking nut, and the upper cover plate is stably fitted by cooperating with the sliding groove at the front end. When the compressor is working, the heat generated will rise. The fan below the second mounting plate will generate a downward airflow to carry the heat to the bottom, and dissipate heat through the vents on the grid connecting plate and the side plate. The cooling fan will also directly act on the compressor for heat dissipation.

[0016] Preferably, a controller is installed at the end of the support tube; an emergency stop switch, a power switch, an ECG connector, and a finger pulse connector are also provided on the first mounting plate; the controller is electrically connected to the ECG connector, the finger pulse connector, the air intake solenoid valve, and the exhaust solenoid valve, respectively; the beneficial effect of this preferred embodiment is that by placing the controller at the end of the support tube, the overall appearance is more compact and aesthetically pleasing. The controller can also automatically or manually collect or control data from the ECG connector, the finger pulse connector, the air intake solenoid valve, and the exhaust solenoid valve, resulting in better overall controllability of the equipment.

[0017] Preferably, a mounting base is detachably provided at the bottom of the lower housing, the casters are located at the bottom of the mounting base, and both ends of the handrail pass through the upper housing and are connected to the upper ends of two adjacent vertical air tanks. The advantages of this preferred embodiment are that the mounting base facilitates the installation of the lower housing and ensures its integrity. The need for the mounting base can be determined according to the actual situation, resulting in better versatility. The casters and handrails facilitate the movement of the counterpulsation mobile device, making its movement more effortless. The handrails are located on the vertical air tanks, which improves the connection strength of the handrails and makes them less prone to damage.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. Compared with existing external counterpulsation devices, this solution transforms the structure of the gas storage tank into a structural frame, saving the supporting structure within the structural frame. This achieves weight reduction while ensuring the structural strength of the gas storage tank. In this design, the compressor and connecting gas lines in the gas supply system can be integrated into the interior of the structural frame, greatly improving the overall integration of the device and making it more conducive to miniaturization.

[0020] 2. In this design, the side panels, grid connecting plates, and rear cover plates are part of the upper housing, which reduces the workload during assembly and saves the screws or clips used for connection. At the same time, the upper cover plates are fitted and installed by slotting, further saving the use of fixing components. The upper cover plates in the upper housing are fixed by the cooperation of the bracket tube and the locking nut, and the locking nut is located on the outside of the upper cover plates, making disassembly and assembly convenient.

[0021] During maintenance, simply open the rear cover and the window formed by the structural frame allows for inspection and replacement of parts. For overall disassembly, loosen the locking nut to remove the top cover, and then move the integrated structure of the side panel, grid connecting plate, and rear cover upwards to complete the disassembly. Because it uses fewer screws or other fasteners, disassembly and assembly are more convenient.

[0022] 3. In this solution, the air storage tank is formed by connecting multiple horizontal and vertical air tanks in sequence. Compared with the method of setting a separate air storage tank, it has a larger surface area and better heat dissipation effect. Furthermore, in actual use, the higher temperature part of the compressed air rises under the action of buoyancy, while the lower temperature part of the air sinks. Through the cooling fan set on the top of the second mounting plate, the heat of the upper part of the hot air can be effectively discharged to the outside of the housing through the airflow, i.e., the vents set on the grid connecting plate or the housing.

[0023] 4. This solution is more in line with physical principles when dissipating heat, resulting in better heat dissipation, energy saving, and environmental protection. The structural frame, as an air storage tank, can improve heat dissipation, save space, and ensure support strength. At the same time, this solution reduces the use of the internal support structure of the shell, thus achieving lightweighting. Attached Figure Description

[0035] like Figure 1 , Figure 4 and Figure 5 As shown: An integrated external counterpulsation mobile machine includes a housing 1, a structural frame 2 installed within the housing 1, and a gas supply system 3, wherein, as... Figure 1The housing 1 includes a lower housing 101 and an upper housing 102. The upper housing 102 is mounted around the horizontal circumference of the structural frame 2, and is threaded to the upper surface of the lower housing 101 at the bottom of the structural frame 2; as shown Figure 2 and Figure 4 The structural frame 2 includes multiple vertical air tanks 201 and multiple horizontal air tanks 202. Specifically, a horizontal air tank 202 is installed between each pair of adjacent vertical air tanks 201, and both ends of the horizontal air tank 202 are connected to the vertical air tanks 201 connected thereto; for example... Figure 5 The gas supply system 3 includes a compressor 301 and a connecting gas line 302, wherein the connecting gas line 302 connects the compressor 301 and the structural frame 2, and both the compressor 301 and the connecting gas line 302 are installed inside the structural frame 2.

[0036] The basic principle of this scheme is:

[0037] Unlike existing technologies, where the gas storage tank is a separate component in counterpulsation devices, this solution uses a vertical gas tank 201 and a horizontal gas tank 202 connected together. This forms an integrated external counterpulsation mobile machine housing 1 with a structural frame 2, replacing the internal support structure and effectively reducing the size and weight of the device. Furthermore, the interconnectedness of multiple horizontal gas tanks 202 and vertical gas tanks 201 ensures sufficient gas storage capacity and eliminates the need for multiple air outlets and inlets, simplifying the structure of the frame 2. The compressor 301 and main components of the gas supply system 3, including the connecting gas path 302, are located within the frame 2. This design offers higher integration compared to existing separate gas tanks, facilitating miniaturization of the counterpulsation device. During maintenance, only the upper housing 102 or one side of it needs to be disassembled for inspection through the gaps in the frame 2, making operation convenient.

[0038] When implementing, such as Figure 2 and Figure 4 The structural frame 2 is a cuboid frame. In this design, there are four vertical gas tanks 201, forming the four side ribs of the cuboid frame. The bottom of each vertical gas tank 201 is fixedly installed on the upper side of the lower shell 101. There are at least two sets of horizontal gas tanks 202, and the two ends of each set of horizontal gas tanks 202 are connected to the adjacent vertical gas tanks 201. There are two horizontal gas tanks 202 in one set in the horizontal direction of the cuboid frame, located on the upper side of one opposite face of the cuboid frame. Fifthly, setting the structural frame 2 as a cuboid frame is more conducive to the assembly of the upper shell 102 and the lower shell 101, and the structure is simple. Welding one set of horizontal gas tanks 202 to the upper side of the structural frame 2 leaves enough open window, which provides sufficient operating space for maintenance, which is simple and convenient.

[0039] When implementing, such as Figure 2 and Figure 3 A first mounting plate 203 is provided on the upper part of the structural frame 2. The two ends of the first mounting plate 203 are respectively connected to the upper parts of two adjacent vertical air tanks 201. Multiple connectors 204 are installed on the first mounting plate 203. The connectors 204 include air inlet connectors 205 (the upper row) and air outlet connectors 206 (the lower row). The specific number of connectors 204 can be set according to the actual situation. The advantage of this setting is that by placing the first mounting plate 203 on the upper part of the adjacent vertical air tanks 201, the multiple connectors 204 on it have a certain height, which facilitates the connection of the connectors 204 for the exhaust and intake of the counterpulsation device, so as to ensure the smooth operation of external counterpulsation.

[0040] During implementation, the gas supply system 3, as shown in Figure 3, is a gas supply system. Figure 5 As shown, the compressor 301 is fixedly mounted on the upper part of the lower housing 101 by screws, and a shock-absorbing pad 303 is installed between the compressor 301 and the lower housing 101. In a specific implementation, the connecting air passage 302 includes an air injection pipe 304. One end of the air injection pipe 304 is connected to the air outlet of the compressor 301, and the other end of the air injection pipe 304 is connected to the air inlet of the air storage tank composed of the structural frame 2. Specifically, a silencer box 305 is connected in series with the air inlet of the compressor 301. In this embodiment, the installation of the shock-absorbing pad 303 between the compressor 301 and the lower housing 101 is beneficial to reducing the vibration and noise generated when the compressor 301 is running. The installation of the silencer box 305 at the air inlet of the compressor 301 is beneficial to reducing the noise when the compressor 301 is running and when it is exhausting.

[0041] When implementing, such as Figure 5 The connecting air passage 302 includes an outlet pipe 306 and an exhaust pipe 307. Specifically, one end of the outlet pipe 306 is connected to the outlet of the structural frame 2, and the other end is connected to the inlet connector 205. An inlet solenoid valve 308 is also installed on the outlet pipe 306. One end of the exhaust pipe 307 is connected to the exhaust connector 206, and the other end is connected to the silencer box 305. An exhaust solenoid valve 309 is also connected to the exhaust pipe 307. The advantage of this arrangement is that the structural frame 2 is composed of multiple interconnected air storage tanks, through... The exhaust pipe 306 is designed to output compressed gas for external counterpulsation. The intake solenoid valve 308 controls the exhaust speed and volume. The exhaust pipe 307 discharges the gas used for counterpulsation after the counterpulsation. The connected silencer 305 effectively reduces the noise during exhaust, improving the quietness and comfort during counterpulsation. At the same time, the gas passing through the silencer 305 returns to the structural frame 2 via the compressor 301. Since the recovered gas has a certain pressure, the compressor 301 consumes less energy.

[0042] When implementing, such as Figure 1 The upper shell 102 includes two side plates 103, which are symmetrically snapped onto both sides of the structural frame 2. A grid connecting plate 104 is integrally formed or snapped onto the front end of each side plate 103, and the two ends of the grid connecting plate 104 are respectively connected to the corresponding side plate 103. A rear cover 105 is provided on the other side of each side plate 103, and the two ends of the rear cover 105 are respectively connected to the two side plates 103. The advantage of this arrangement is that the grid connecting plate 104 can not only serve as a connection but also facilitate airflow exchange with the outside, which is convenient for heat dissipation and air intake. The side plates 103, the rear cover 105, and the grid connecting plate 104 constitute most of the upper shell 102, which can be directly fitted onto the structural frame 2 during assembly, effectively reducing the assembly process and difficulty.

[0043] When implementing, such as Figure 1 The upper housing 102 also includes an upper cover plate 106, which is an L-shaped cover plate. One end of the L-shaped cover plate is slidably connected in the groove, and the other two sides of the L-shaped cover plate are respectively connected to the top of the two side plates. The top of the two side plates is recessed on the opposite side and then cooperates with the horizontal part of the L-shaped cover plate, so that the upper surface of the upper housing 102 is flat and easy to assemble. In this embodiment, the grooves opened in front of the two side plates 104 allow the vertical section of the L-shaped cover plate to be directly inserted into the groove during assembly, and then the horizontal section of the L-shaped cover plate is overlapped with the top of the side plate 104. This effectively reduces the assembly difficulty and workload, and also reduces the amount of screws or clips used, making it simple and convenient.

[0044] When implementing, such as Figure 2 and Figure 5To facilitate the locking of the upper cover plate 106, a second mounting plate 107 is welded between a group of horizontal gas tanks 202 located at the upper end of the vertical gas tank 201. A support tube 108 is welded to the upper surface of the second mounting plate, passing through the upper cover plate 106. A locking nut 109 is provided on the support tube 108, and when the upper cover plate is locked, the bottom of the locking nut 109 abuts against the upper part of the upper cover plate 209. A cooling fan 110 is provided at the lower part of the second mounting plate 107. The advantage of this arrangement is that, since the upper cover plate 106 may be in contact with the side plates 103 after installation... There will still be some looseness, so the upper cover plate 106 needs to be fixed. The upper cover plate 106 is clamped between the support tube 108 and the second mounting plate 107 by the cooperation of the set support tube 108 and the locking nut 109. The upper cover plate 106 is then stably fitted by cooperating with the sliding groove at the front end. When the compressor 301 is working, the heat generated will rise. The fan 110 below the second mounting plate 107 will generate a downward airflow to carry the heat to the bottom and dissipate heat through the ventilation holes on the grid connecting plate 104 and the side plate 103. The cooling fan 110 will also directly act on the compressor for heat dissipation.

[0045] When implementing, such as Figure 1 , Figure 2 and Figure 3 A controller 111 is installed at the upper end of the stent tube 108; an emergency stop switch 207, a power switch 208, an ECG connector 209, and a finger pulse connector 210 are also provided on the first mounting plate; the controller 111 is electrically connected to the ECG connector 209, the finger pulse connector 210, the intake solenoid valve 308, and the exhaust solenoid valve 309 respectively; in this embodiment, the controller 111 is installed at the end of the stent tube 108, making the overall appearance more compact and beautiful, and easier to operate. The controller 111 can also automatically or manually collect data or control the ECG connector 209, the finger pulse connector 210, the intake solenoid valve 308, and the exhaust solenoid valve 309, making the overall control performance of the external counterpulsation device better.

[0046] When implementing, such as Figure 1 and Figure 2A mounting base 112 is detachably provided at the bottom of the lower housing 101, and casters 113 are provided around the bottom of the mounting base 112. A handrail 114 is provided on the upper part of the upper housing 102, and both ends of the handrail 114 pass through the upper housing 102 and are connected to the upper ends of two adjacent vertical air tanks 201. The mounting base 112 facilitates the installation of the lower housing 101, ensuring the integrity of the lower housing 101. The need for the mounting base 112 can be determined according to the actual situation, which improves its versatility. The casters 113 and the handrail 114 facilitate the movement of the counterpulsation mobile machine, making it easier to move. The handrail 114 is located on the vertical air tank 201, which makes the connection strength of the handrail 114 better and less prone to damage.

[0047] The beneficial effects of this utility model are as follows:

[0048] Compared with existing external counterpulsation devices, this solution transforms the structure of the gas storage tank into a structural frame 2, saving the supporting structure within the shell 1. This achieves weight reduction while maintaining the structural strength of the gas storage tank. In this design, the compressor 301 and connecting gas passage 302 in the gas supply system 3 can be integrated into the interior of the structural frame 2, greatly improving the overall integration of the device and facilitating its miniaturization. The side plate 103, grid connecting plate 104, and rear cover plate 105 are part of the upper shell 102, reducing assembly workload and saving the screws or clips used for connection. The upper cover plate 106 is fitted with slots. The installation further reduces the use of fixing components; the upper cover plate 106 in the upper housing 102 is fixed by the cooperation of the bracket tube 108 and the locking nut 109, and the locking nut 109 is located on the outside of the upper cover plate 106, making disassembly and assembly convenient; during maintenance, only the rear cover 105 needs to be opened, and the inspection and component replacement can be achieved through the window formed at the rear end of the structural frame 2. When disassembling the whole, the locking nut 109 can be opened to remove the upper cover plate 106, and then the integrated structure of the side plate 103, the grid connecting plate 104 and the rear cover 105 can be moved upward to complete the disassembly. Since there are fewer screws or other fasteners, disassembly and assembly are more convenient.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims.
