Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a reinforced structure of a portable external counterpulsation device. Background Art

[0002] EECP is a method of non-invasively pressing the lower body externally to relieve and eliminate angina symptoms and improve the hypoxic-ischemic state of important organs of the body. It is also a medical device used to prevent and treat cardiovascular and cerebrovascular diseases. Traditional EECP devices use air bags wrapped around the limbs and buttocks to inflate and pressurize the air bags during the diastole of the heart, prompting blood from the limb arteries and veins to return to the heart, significantly increasing diastolic pressure, improving blood perfusion of important organs such as the heart and brain, and reducing cardiac afterload; during the systole of the heart, the air bags are quickly deflated, the pressure is relieved, and the systolic pressure in the aorta is reduced, minimizing the resistance of the heart's ejection phase, and accelerating the blood flow to the distal end, thereby achieving the counterpulsation effect.

[0003] Traditional extracorporeal counterpulsation devices usually include a counterpulsation bed and a control host. The counterpulsation bed is internally integrated with components such as an air compressor, a frequency converter, an air tank, and a solenoid valve group. It weighs 400-500 kilograms and is not convenient to move, so it is only suitable for hospitals. When patients need to use extracorporeal counterpulsation devices for rehabilitation treatment, they need to go to the hospital every day, which is very inconvenient for patients. In response to the above problems, miniaturized extracorporeal counterpulsation devices have appeared in the industry, which are easy to move, but the way to achieve movement is to install pulleys at the bottom, which is not convenient for transportation and other application scenarios. Summary of the invention

[0004] The object of the present invention is to provide a reinforced structure of a portable external counterpulsation device which has high structural strength and is easy to carry.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a reinforcement structure of a portable external counterpulsation device, including a box body, a handle is arranged on the side of the box body, and a reinforcement plate is arranged at a position corresponding to the handle in the box body and the two are fixedly connected.

[0006] Furthermore, the reinforcing plate includes a strip, the length direction of the strip is arranged in the vertical direction, a ring is provided at the upper end of the strip, the ring is sleeved on the outer periphery of the handle and fixed, and the lower end of the ring is fixed to the isolation box for installing the compressor.

[0007] Furthermore, the isolation box is arranged at the lower part of the box body, and the isolation box includes a first chamber and a second chamber distributed laterally. The compressor is placed and fixed in the first chamber, the motor driver and the switching power supply are arranged in the second chamber, and the lower end of the strip is fixed to the top plate of the isolation box by bolts.

[0008] Furthermore, a retaining ring extends from the inner wall of the box toward the inner cavity, the retaining ring abuts against the upper part of the top plate and forms a limiting fit, a mounting plate is provided at the lower end of the strip, and bolts pass through the mounting plate, the retaining ring and the through holes on the top plate in sequence to fix the three together.

[0009] Furthermore, the handle is an embedded structure, including a groove sunken into the inner cavity of the box, a buckle plate is provided on the top of the inner wall of the groove protruding downward, the groove forms a raised portion in the inner cavity of the box, and the ring of the reinforcing plate is sleeved on the outer periphery of the raised portion and fixedly connected by bolts.

[0010] Furthermore, the cross section of the collar is in the shape of a rectangular plate with a certain width, and the rectangular plate fits the outer periphery of the raised portion.

[0011] Furthermore, the strips are arranged close to the inner wall of the box, and reinforcing ribs are arranged at the connection between the strips, the collar and the mounting plate.

[0012] Furthermore, a set of handles and reinforcement plates are symmetrically arranged on both sides of the box body.

[0013] In the above solution, since the EVCP device has a certain weight, considering safety and reliability, a reinforcing plate is provided inside the box corresponding to the handle to enhance the structural strength of the handle and ensure safety and reliability when the handle is lifted. When there is a need to transport the EVCP device, only the handle needs to be lifted to switch between different application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] According to the content of "Handles and other lifting devices" in clause 9.4.4 of GB9706.1-2020 standard, requirement c) the lifting devices or handles on portable ME equipment should be able to withstand the following loading test: the handles and their accessories can withstand an external force of 4 times the weight of the ME equipment applied in any direction during normal use and transportation. These requirements ensure the safety and reliability of medical electrical equipment during movement and operation, and prevent equipment from falling or operating errors caused by damage to the handles or lifting devices.

[0016] Combine the following Figure 1-Figure 6 The present invention is described in further detail.

[0017] like Figure 1-Figure 3 As shown, a reinforced structure of a portable external counterpulsation device includes a box body 10, a handle 20 is arranged on the side of the box body 10, and a reinforcing plate 30 is arranged at a position corresponding to the handle 20 in the box body 10, and the two are fixedly connected. The external counterpulsation device in the present invention is a miniaturized, light-weight, and easy-to-carry integrated device. In order to meet the purpose of easy carrying, a handle 20 is arranged on the side of the box body 10. When there is a need to transport the external counterpulsation device, only the handle 20 needs to be lifted to achieve switching between different application scenarios. Since the external counterpulsation device has a certain weight, considering safety and reliability, a reinforcing plate 30 is arranged inside the box body 10 corresponding to the handle 20 to enhance the structural strength at the handle 20 and ensure safety and reliability when lifting the handle 20.

[0018] As a preferred embodiment of the present invention, refer to Figure 3-Figure 5 The reinforcing plate 30 includes a strip 31, the length direction of the strip 31 is arranged in the vertical direction, a collar 32 is provided at the upper end of the strip 31, the collar 32 is sleeved and fixed on the outer periphery of the handle 20, and the lower end of the collar 32 is fixed to the isolation box 40 for installing the compressor 41. In the entire EVCP device, the compressor 41 is the heaviest part, so the lower end of the strip 31 is directly fixed to the isolation box 40 for installing the compressor, and the collar 32 at the upper end of the strip 31 is sleeved on the outer periphery of the handle 20. When the handle 20 is lifted, it is equivalent to lifting the collar 32, and the isolation box 40 and its internal accessories are lifted by the strength of the reinforcing plate 30, instead of using the handle 20 body made of plastic or other non-metallic materials to lift the isolation box 40 and its internal accessories. The handle 20 only plays the role of being easy to carry and grasp, thereby ensuring the safety and reliability of lifting.

[0019] Further, such as Figure 6As shown, the isolation box 40 is arranged at the lower part of the box body 10, and the isolation box 40 includes a first chamber 42 and a second chamber 43 which are distributed laterally, a compressor 41 is placed in the first chamber 42 and fixed, a motor driver 44 and a switching power supply 45 are arranged in the second chamber 43, and the lower end of the strip is fixed to the top plate 46 of the isolation box 40 by bolts. Here, the isolation box 40 for installing the compressor 41, the motor driver 44 and the switching power supply 45 is arranged at the lower part of the box body 10, and the compressor 41 is the heaviest component among all the components of the entire external counterpulsation device. This arrangement ensures the stability of the entire external counterpulsation device.

[0020] In order to ensure the stability of the position of the isolation box 40, the inner wall of the casing 10 extends to the inner cavity with a retaining ring 11, which is blocked on the top plate 46 and forms a limit fit, so that the position of the isolation box 40 is limited to the bottom of the casing 10, and the stability of the whole counterpulsation device is further enhanced. In addition, the lower end of the strip 31 is provided with a mounting plate 33, and bolts pass through the through holes provided on the mounting plate 33, the retaining ring 11 and the top plate 46 in sequence to fix the three together. The mounting plate 33 is an angle that fits the upper plate surface of the retaining ring 11, and it is best that the plate surface is in the horizontal plane. Because the retaining ring 11 is integrally formed with the casing 10, the bolts directly fix the mounting plate 33, the casing 10 and the isolation box 40 together to improve the overall strength.

[0021] In order to facilitate carrying and grasping by hand, the handle 20 is an embedded structure, including a groove 21 sunken into the inner cavity of the box body 10, and a buckle plate 22 is provided on the top of the inner wall of the groove 21 protruding downward. By putting the hand into the groove 21 and buckling the buckle plate 22, the box body 10 can be lifted tightly. The groove 21 forms a raised portion in the inner cavity of the box body 10, and the ring 32 of the reinforcing plate 30 is sleeved on the outer periphery of the raised portion and fixedly connected by bolts, which is equivalent to putting the hand into the ring 32 and lifting the ring 32.

[0022] In order to further improve the overall strength, the cross-section of the ring 32 is a rectangular plate with a certain width, and the rectangular plate fits the outer periphery of the raised portion, so that the handle 20 is evenly stressed to avoid stress concentration.

[0023] The strip plate 31 is arranged close to the inner wall of the box body 10, which plays a role of a skeleton to prevent the box body 10 from deforming, and does not hinder the arrangement of other components in the box body 10. The strip plate 31 is connected with the ring 32 and the mounting plate 33 with reinforcing ribs to further increase the overall strength of the reinforcing plate 30.

[0024] Furthermore, a set of handles 20 and reinforcing plates 30 are symmetrically arranged on both sides of the box 10, so that one person can carry it, or two people can carry it on each side. The entire EVCP device is 55 cm long, 34 cm wide, and 60 cm high. It is small in size and occupies little space. It is suitable for multiple scenarios in hospitals and homes, and weighs only 25 kg. An adult can also carry and transport it easily.

[0025] The above shows and describes the basic principles, main features and characteristics of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
