Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an anti-bounce external counterpulsation device. Background Art

[0002] As an important medical device for assisting the treatment of cardiovascular diseases, the core working principle of the external counterpulsation device is to apply external pressure to the human limbs through the periodic inflation and deflation of the cuff, so as to promote the limb blood reflux, thereby improving the heart blood supply and blood circulation. The existing external counterpulsation device mainly includes core components such as the cuff assembly, the control system, the air supply system, the monitoring system and the counterpulsation bed. Among them, the air supply system, as a key part to realize the inflation and deflation function of the cuff, is usually composed of a gas supply unit and a gas diversion connection seat. The gas diversion connection seat is fixedly connected to the bottom of the bed cover of the counterpulsation bed, and a plurality of connectors are arranged on the side close to the bed cover. The bed cover and the mattress of the counterpulsation bed are provided with through holes, and the connectors are located in the through holes. Each connector is connected to a trachea, and the trachea is connected to the cuff arranged above the counterpulsation bed. A plurality of inflation and exhaust ports are provided on the side of the gas diversion connection seat away from the counterpulsation bed, and each connector is connected to the corresponding inflation and exhaust port to form a gas transmission channel. The gas supply unit is connected to the inflation and exhaust ports to realize the function of inflating and discharging the gas in the cuff. During the treatment, the control system accurately controls the inflation and deflation timing of the cuff based on the patient's electrocardiogram signals and other physiological parameters collected in real time by the monitoring system, thus ensuring the safety and effectiveness of the treatment.

[0003] However, the existing technical solutions have obvious defects. In order to meet the treatment needs of patients of different heights and body shapes, existing devices generally adopt the design of lengthening the trachea to improve the versatility of the equipment. However, the structural design of the gas diversion connector fixed under the bed cover of the counterpulsation bed causes the connector to be too close to the patient's body. When the cuff is inflated, the upward lifting force generated by the filling of the trachea will directly act on the patient's body. For patients with lighter weight, this lifting force can easily cause their bodies to detach from the mattress, causing the patient's body to be in an unstable state during treatment. This unstable state not only seriously affects the patient's treatment experience, but also significantly increases the risk of accidents occurring to the patient during treatment, posing a direct threat to the patient's treatment safety and physical health. Utility Model Content

[0004] The utility model aims to provide an anti-bounce external counterpulsation device to ensure the stability and safety of the treatment process.

[0005] To achieve the above object, the utility model adopts the following technical solution: An anti-ballistic extracorporeal counterpulsation device, including a counterpulsation bed and a gas supply system. A fixed seat is fixedly connected below the bed cover of the counterpulsation bed. The fixed seat includes a bottom plate and side plates obliquely arranged on opposite sides of the bottom plate. The lower ends of the side plates are fixedly connected to the bottom plate, and the upper ends of the side plates are fixedly connected to the counterpulsation bed. The space between the counterpulsation bed and the bottom plate forms an outward-expanded adjustment chamber; the gas supply system includes a gas supply unit and a gas distribution connection seat. The gas distribution connection seat is fixedly connected below the bottom plate, and several quick connectors are provided on the side close to the bottom plate. The bottom plate is provided with first through holes corresponding to the quick connectors; Each quick connector is connected with a trachea, and the trachea passes through the counterpulsation bed and is connected with a bladder sleeve above it; The gas supply unit is installed on the gas distribution connection seat and can realize the functions of inflating the bladder sleeve and discharging the gas in the bladder sleeve.

[0006] The beneficial effect of this solution is: In this technical solution, by designing the space between the counterpulsation bed and the bottom plate as an outward-expanded adjustment chamber and moving the gas distribution connection seat down to the bottom of the bottom plate, the force-bearing points of the quick connectors are greatly reduced. When the trachea is inflated, the upward lifting force generated by the gas filling is effectively buffered by the trachea in the adjustment chamber, avoiding the direct action of the lifting force on the patient's body. This change in the mechanical conduction path enables even patients with a relatively light weight to maintain body stability during the treatment process, fundamentally eliminating the accidental risks caused by body shaking and providing a solid guarantee for the safety of the treatment process.

[0007] Regarding the problem of difficult trachea storage caused by the design of using a lengthened trachea in the existing device, the adjustment chamber formed by the bottom plate and the counterpulsation bed in this solution provides a dedicated storage space for the long trachea. Medical staff can flexibly adjust the pulling-out length of the trachea in the adjustment chamber according to the actual body type of the patient, which can not only ensure the close fit of the bladder sleeve to the patient's body but also avoid the problems of entanglement and mess caused by the overlong trachea, realizing the efficient adaptation of the device to patients with different heights and body types and significantly improving the clinical practicability of the device.

[0008] The outward-expanded adjustment chamber provides a space for the trachea to extend obliquely. When the trachea passes through the counterpulsation bed, it can be supported and guided by the side plates and extend to the bladder sleeve at a smoother angle. This layout reduces the bending degree of the trachea in the chamber, not only reducing the gas transmission resistance and ensuring the inflation and deflation efficiency but also avoiding blockage or damage of the trachea due to excessive bending, improving the reliability of the gas supply system.

[0009] Furthermore, the counterpulsation bed includes a bed frame, a bed cover is fixedly connected to the top of the bed frame, a mattress is laid above the bed cover, several second through holes for the trachea to pass through are provided on the bed cover, and several third through holes for the trachea to pass through are provided on the mattress.

[0010] The beneficial effects of this solution are as follows: In this technical solution, a mattress is laid above the bed cover. The mattress can provide a soft and comfortable support surface for the patient, significantly improving the body sensation comfort during the treatment process and avoiding the pressure and discomfort caused by the hard bed cover. At the same time, the second and third through holes on the bed cover and the mattress form a through path, enabling the trachea to extend from the bottom of the counterpulsation bed through the interior of the bed body to above the mattress, avoiding the risk of compression or entanglement of the trachea exposed to the patient.

[0011] Furthermore, the gas shunt connection seat includes a shunt plate and a mounting plate. The mounting plate is fixedly connected below the fixed seat, the shunt plate is hermetically connected below the mounting plate, and several air charging and discharging ports are provided at the bottom of the shunt plate. The air supply unit is communicated with the air charging and discharging ports; the quick connectors are installed on the top of the mounting plate, and each quick connector is connected to the corresponding air charging and discharging port at the bottom of the shunt plate to form a gas transmission channel.

[0012] The beneficial effects of this solution are as follows: By splitting the gas shunt connection seat into a combined structure of a shunt plate and a mounting plate, a functional modular design is realized. The fixed connection between the mounting plate and the fixed seat ensures the stability of the installation of the shunt device; the hermetic connection between the shunt plate and the mounting plate effectively prevents gas leakage and ensures the stable pressure of the air supply system. The corresponding communication design between the air charging and discharging ports and the quick connectors makes the gas transmission path clear and the layout regular, facilitating the accurate distribution of air flow to each trachea and cuff, improving the inflation efficiency and uniformity. At the same time, the modular structure is convenient for later disassembly, maintenance and replacement of components, reducing the maintenance difficulty and improving the reliability and service life of the equipment.

[0013] Furthermore, the air supply unit includes a compressor and a gas storage tank. The gas storage tank is communicated with the outlet of the compressor. Several air supply main pipes are provided on the gas storage tank. The air supply main pipes are in one-to-one correspondence and communication with the air charging and discharging ports at the bottom of the shunt plate, and a two-way solenoid valve is installed on each air supply main pipe.

[0014] The beneficial effects of this solution are as follows: Adopting the air supply mode of "compressor + gas storage tank" can ensure a stable and sufficient air source supply. The compressor continuously works to inflate the gas storage tank, and the gas storage tank serves as a buffer unit, effectively avoiding air pressure fluctuations caused by instantaneous gas consumption and ensuring a smooth inflation process of the cuff. The corresponding communication design between the air supply main pipe and the air charging and discharging port of the shunt plate makes the gas transmission path clear. With the precise opening and closing control of the two-way solenoid valve, it can not only quickly inflate and pressurize the cuff, but also quickly exhaust and decompress during the cardiac contraction period, accurately matching the rhythm of extracorporeal counterpulsation treatment.

[0015] Furthermore, side doors are hinged on both sides of the bed frame, and the side doors are located at both ends of the fixed seat.

[0016] The beneficial effects of this solution are as follows: Due to the setting of the side door, this technical solution constructs an efficient and convenient maintenance channel. When the trachea is aged, damaged, etc. and needs to be replaced, you only need to open the side door to quickly access the internal trachea without removing the main structures such as the bed cover and the fixed seat, which greatly simplifies the replacement process and significantly improves maintenance efficiency. At the same time, the side door can effectively shield the trachea and other internal components, which can not only keep the appearance of the counterpulsation bed neat, but also prevent patients from accidentally touching the trachea and causing accidents, taking into account both practicality and safety.

[0017] Furthermore, universal wheels are installed on the four corners of the bottom of the bed frame.

[0018] The beneficial effects of this solution are as follows: the universal wheels installed at the four corners of the bottom of the bed frame give the device flexible mobility. Medical staff can easily push the device to move between different areas such as wards and treatment rooms to quickly respond to patient treatment needs. The 360-degree free steering feature of the universal wheels allows the device to flexibly adjust its direction in a small space, avoiding collisions with surrounding equipment and walls, and reducing the risk of equipment damage. At the same time, during emergency treatment, the device can be quickly moved to the patient's side, improving the efficiency of medical resource allocation, and greatly enhancing the convenience and clinical applicability of the external counterpulsation device.

[0024] Example

[0025] This embodiment provides a stable and safe anti-bounce external counterpulsation device, which can adapt to patients of different heights and body shapes through structural innovation, especially ensuring the stability of light patients during treatment. The specific implementation of the device is described in detail below, and the related structures not innovated by this patent adopt the existing technology and are not described here.

[0026] likeFigure 1 A bulletproof extracorporeal counterpulsation device as shown, including a counterpulsation bed and a gas supply system.

[0027] As Figure 1-2 shown, the counterpulsation bed includes a bed frame 1, and the bed frame 1 serves as a basic support structure. A bed cover 2 is installed on its top through bolts. A number of second through holes 12 are opened on the bed cover 2. A mattress 3 is laid above the bed cover 2. A number of third through holes 13 are opened on the mattress 3. The mattress provides a comfortable treatment position for the patient. In addition, universal wheels 4 are installed at the four corners of the bottom of the bed frame 1, facilitating the flexible movement and position adjustment of the device.

[0028] As Figure 1-2 shown, a fixing seat 5 is installed on the bed frame 1 below the bed cover 2 through bolts. The fixing seat 5 includes a bottom plate and side plates inclined on the left and right sides of the bottom plate. The included angle between the side plates and the horizontal direction is 55° - 60°. There are two second through holes 12 near one side of the side plates above the side plates. The lower ends of the side plates are installed on the bottom plate through bolts, and the upper ends of the side plates are installed on the bed frame 1 at the bottom of the bed cover 2 through bolts. The space between the bottom plate and the bed cover 2 forms an outward-expanded adjustment chamber 6, and the height of the adjustment chamber 6 is 20 - 25 cm; it is convenient to store the trachea 14 and avoid problems such as entanglement and mess caused by the excessive length of the trachea 14. Side doors 7 are hinged on the front and rear sides of the bed frame 1. The side doors 7 are located at both ends of the fixing seat 5. It should be noted that the front and rear sides of the fixing seat 5 are its two ends, and the left and right sides of the fixing seat 5 are defined as its two sides. When the side doors 7 are closed, they can block the internal trachea 14 and improve the aesthetics of the counterpulsation bed; when opened, it is convenient to directly touch the trachea 14 and quickly complete the maintenance or replacement operation, optimizing the maintenance convenience. In this embodiment, the height of the adjustment chamber is 22 cm, and the included angle between the side plates and the horizontal direction is 58°. In this technical solution, the included angle between the side plates and the horizontal direction is set to 55° - 60°, making the space of the adjustment chamber 6 more open and the spatial distribution in the horizontal and vertical directions more reasonable, providing sufficient space for the layout of the trachea 14. This angle can also make the two second through holes 12 accurately located above the side plates. When the trachea 14 led out from the quick connector 11 of the gas shunt connection seat passes through the bed cover 2, it can be supported and guided by the side plates, and the routing can be more reasonably planned. After the trachea 14 passes through the second through holes 12 above the side plates, it can extend to the bladder sleeve 15 above the mattress 3 at a more natural angle, reducing the bending degree in the adjustment chamber 6. This is not only beneficial to the smooth transmission of gas but also reduces the possibility of blockage or damage of the trachea 14 due to excessive bending, improving the stability and reliability of the gas supply system.

[0029] As Figure 2-3As shown in the figure, the air supply system includes an air supply unit and a gas shunt connection seat. The gas shunt connection seat includes a shunt plate 8 and a mounting plate 9. The mounting plate 9 is mounted below the fixed seat 5 by bolts. The shunt plate 8 is sealingly connected below the mounting plate 9. Three air charging and discharging ports 10 are provided at the bottom of the shunt plate 8. A number of quick connectors 11 are mounted on the top of the mounting plate 9. Each quick connector 11 is communicated with the corresponding air charging and discharging port 10 at the bottom of the shunt plate 8 to form a gas transmission channel. A first through hole corresponding to the quick connector 11 is provided at the bottom of the fixed seat 5, and the quick connector 11 can pass through the first through hole. A number of second through holes 12 are provided on the bed cover 2, and a number of third through holes 13 are provided on the mattress 3. An air pipe 14 is connected to each quick connector 11. The air pipe 14 passes through the second through hole 12 and the third through hole 13 in sequence and extends above the mattress 3. An airbag sleeve 15 is mounted at the upper end of the air pipe 14. The air supply unit includes a compressor and a gas storage tank. The compressor and the gas storage tank are both mounted on the bed frame 1 below the gas shunt connection seat by bolts. The gas storage tank is communicated with the air outlet of the compressor. Three air supply main pipes are connected to the gas storage tank. The air supply main pipes correspond to and are communicated with the air charging and discharging ports 10 at the bottom of the shunt plate 8 one by one. A two-way solenoid valve is mounted on each air supply main pipe to control the charging and discharging of the gas.

[0030] The specific implementation process is as follows:

[0031] During the treatment process, the patient lies on the mattress 3, and the airbag sleeve 15 is wrapped around the patient's lower limbs and buttocks. The control system accurately controls the operation of the compressor and the two-way solenoid valve according to the patient's physiological parameters (such as electrocardiogram signals) collected by the monitoring system in real time, realizing the accurate regulation of the air charging and discharging timing of the airbag sleeve 15, and providing a reliable guarantee for the treatment safety and effect.

[0032] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics known in the solutions are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
