Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to an external counterpulsation device. Background Technology

[0002] External counterpulsation (ECP) devices are key equipment in the adjuvant treatment of cardiovascular diseases, and their structural design directly affects treatment efficacy and patient safety. Existing devices mainly consist of a gas supply system, a control system, a monitoring system, a counterpulsation bed, and a balloon assembly. These components work together to achieve the treatment function. Specifically, the balloon is located at the top of the counterpulsation bed, and a first-order male connector mounted on it connects to the gas supply system via an endotracheal tube. The gas supply system includes a gas supply unit and a gas shunt connector. The gas shunt connector is fixed under the bed cover of the counterpulsation bed, and several second-order male connectors are located on the side near the bed cover. Both the bed cover and mattress of the counterpulsation bed have through holes, and the connectors are located within these holes. Both ends of the endotracheal tube have female connectors, which are threaded to the first and second-order male connectors, respectively. The gas supply unit is installed on the gas shunt connector and is responsible for inflating and deflating the balloon. During treatment, the control system precisely regulates the timing of balloon inflation and deflation based on real-time physiological parameters such as the patient's electrocardiogram collected by the monitoring system, ensuring the safety and effectiveness of the treatment.

[0003] However, this technical solution has significant drawbacks in practical applications: Firstly, while an extended trachea design is used to accommodate patients of different body types, the structure of the gas shunt connector fixed to the bottom of the counterpulsation bed results in the No. 2 connector being too close to the patient's body. When the cuff is inflated, the lifting force generated by the inflation of the gas in the trachea can easily cause lighter patients to detach from the mattress, leading to instability in their physical condition during treatment. Secondly, the cuff and trachea, as well as the trachea and gas shunt connector, are all connected by threads. In clinical practice, repeated twisting and turning are required to complete the assembly and disassembly, which is not only cumbersome and time-consuming, but also prone to loosening due to thread wear after long-term use, causing gas leakage problems. This, in turn, affects the accuracy of cuff inflation and deflation, threatening the treatment effect and equipment reliability. Utility Model Content

[0004] This utility model aims to provide an external counterpulsation device to solve the problem in the prior art where the gas shunt connector is fixed to the bottom of the counterpulsation bed, causing the No. 2 connector to be close to the patient's body, which in turn leads to instability during treatment. At the same time, it improves the defects of the threaded connection, such as cumbersome disassembly and assembly and easy leakage.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an external counterpulsation device, including a counterpulsation bed, a gas supply system, and several air tubes. A U-shaped fixing seat is fixedly connected to the bottom of the counterpulsation bed cover; several sleeves are provided on the top of the counterpulsation bed, and each sleeve is equipped with a No. 1 male connector; the gas supply system includes a gas diversion connector and a gas supply unit. The gas diversion connector is fixedly connected to the bottom of the U-shaped fixing seat. Several No. 2 male connectors are installed on the side of the gas diversion connector near the U-shaped fixing seat. The U-shaped fixing seat has a No. 1 through hole corresponding to the connector. Both ends of the air tubes are equipped with female connectors. The No. 2 male connector engages with the female connector at one end of the air tube, and the female connector at the other end of the air tube passes through the counterpulsation bed and engages with the No. 1 male connector; the gas supply unit is installed on the gas diversion connector and can realize the function of inflating and deflating the air tubes.

[0006] The beneficial effects of this solution are as follows: This technical solution upgrades the device's performance through structural innovation and optimized connection methods. First, it focuses on enhancing treatment stability and safety. Addressing the issue that existing devices, due to the gas shunt connector being fixed under the counterpulsation bed's cover, cause the second connector to be close to the patient, and the tracheal inflation lifting force can easily cause lighter patients to detach from the mattress, this solution adds a U-shaped fixing seat to the bottom of the counterpulsation bed, moving the gas shunt connector lower and fixing it there. By adjusting the chamber and changing the transmission path of the tracheal lifting force, the force generated by gas inflation is effectively dispersed, significantly reducing patient body displacement and eliminating monitoring signal fluctuations and unexpected risks caused by body movement at the source, thus significantly improving treatment safety and comfort.

[0007] Secondly, it improves the stability of treatment effects and maintenance efficiency. The use of snap-fit ​​connections instead of traditional threaded connections allows for quick and easy installation and removal of the endotracheal tube without the need for screwing, significantly reducing clinical maintenance time and improving efficiency. This design achieves a tight fit through mechanical snap-fit, avoiding loosening issues caused by wear and tear from threaded connections over time. The structural design eliminates the risk of gas leakage, ensuring the airtightness and stability of the gas supply system, thus guaranteeing that the treatment effect of the external counterpulsation device is not affected by wear and tear on connecting components. Furthermore, the operation requires no additional tools, reducing maintenance difficulty and providing convenience for quick replacement of the cuff or inspection of the endotracheal tube in clinical practice, further enhancing the reliability and safety of the equipment.

[0008] Furthermore, the U-shaped fixation seat includes a base plate and side plates inclined on opposite sides of the base plate. The lower end of the side plates is fixedly connected to the base plate, and the upper end of the side plates is fixedly connected to the counterpulsation bed. The space between the counterpulsation bed and the base plate forms an outwardly expanding adjustment chamber.

[0009] The beneficial effects of this solution are as follows: Addressing the challenges of tracheal tube storage caused by the extended trachea design in existing devices, this solution provides a dedicated storage space for the long trachea within the adjustable chamber formed by the base plate and the counterpulsation bed. Medical staff can flexibly adjust the length of the trachea pulled out within the adjustable chamber according to the patient's actual body shape. This ensures a close fit between the cuff and the patient's body while avoiding entanglement and clutter caused by excessively long trachea. This achieves efficient adaptation of the device to patients of different heights and body types, significantly improving the device's clinical usability.

[0010] The outward-expanding adjustable chamber provides space for the trachea to extend at an angle. As the trachea passes through the counterpulsation bed, it can be guided by the support of the side plates to extend into the cuff at a smoother angle. This layout reduces the degree of bending of the trachea within the chamber, which reduces gas transmission resistance, ensures efficient inflation and deflation, and prevents blockage or damage to the trachea due to excessive bending, thereby improving the reliability of the gas supply system.

[0011] Furthermore, the gas supply unit includes a compressor, a No. 1 gas storage tank, and a No. 2 gas storage tank. The outlet of the compressor is connected to the No. 1 gas storage tank, and the No. 1 gas storage tank is connected to the No. 2 gas storage tank. Several gas supply pipes are connected to the No. 2 gas storage tank. Several filling and discharging ports are provided at the bottom of the gas diversion connection seat. The gas supply pipes and filling and discharging ports correspond one-to-one and are interconnected. Each gas supply pipe is equipped with a two-way solenoid valve to control the filling and discharging of gas.

[0012] The beneficial effects of this solution are as follows: The air supply unit adopts a combined design of "compressor + dual air tanks + bidirectional solenoid valve". The compressor continuously supplies air to the first air tank, which is then pressure-stabilized before being delivered to the second air tank, forming a stable air pressure source. When the bidirectional solenoid valve is open, the compressed air in the second air tank is quickly filled into the bladder through the air supply pipe, achieving precise inflation; when it is opened in the reverse direction, the gas in the bladder is discharged through the bidirectional solenoid valve.

[0013] Furthermore, a connecting tube is fixedly connected to the sheath, and the connecting tube communicates with the inner cavity of the sheath. The first male connector includes a first connecting nut and a first insertion tube. The first insertion tube includes a first threaded section and a first insertion section connected in sequence. The outer wall of the first threaded section is provided with external threads. The first threaded section is threadedly connected to the first connecting nut. The connecting tube is fixed on the first threaded section by the first connecting nut. The first insertion section is inserted into the female connector and engages with the female connector.

[0014] The beneficial effects of this solution are as follows: This technical solution, through the separate design of the connecting tube and the No. 1 male connector, achieves rapid connection between the cuff and the No. 1 male connector while ensuring a tight seal. The snap-fit ​​engagement between the No. 1 insertion section and the female connector allows for quick assembly and disassembly. When the cuff needs to be replaced, simply separating the snap-fit ​​section allows for quick disconnection of the trachea and cuff, without needing to remove the entire connection assembly, significantly improving clinical efficiency. Furthermore, the snap-fit ​​method simplifies the operation while providing stable connection force through mechanical snap-fit, effectively ensuring safety during clinical use.

[0015] Furthermore, each No. 2 male connector is connected to the corresponding inflation / deflation port. The No. 2 male connector includes a fixed section, a positioning section, and a No. 2 threaded section connected in sequence. The No. 2 threaded section is threadedly connected to the gas diversion connector seat. The fixed section is inserted into the female connector and engages with the female connector.

[0016] The beneficial effects of this solution are as follows: This technical solution achieves functional zoning optimization of the connection structure through the segmented design of the fixed section, positioning section and No. 2 threaded section. The snap-fit ​​cooperation between the fixed section and the female connector can quickly complete the disassembly and assembly of the gas tube and the gas diversion connector, significantly improving operational efficiency. The threaded connection between the No. 2 threaded section and the gas diversion connector ensures the stability of the No. 2 male connector on the gas diversion connector.

[0017] Furthermore, each female connector includes a No. 2 connecting nut, a No. 2 insertion tube, and a sliding sleeve. The No. 2 insertion tube comprises a sliding section, a limiting section, a No. 3 threaded section, and a No. 2 insertion section connected in sequence. The air tube is inserted into the No. 2 insertion section and fixed by threaded connection between the No. 2 connecting nut and the No. 3 threaded section. The sliding section is provided with annular limiting rings and annular positioning platforms at intervals. Several mounting holes are provided circumferentially on the sliding section between the annular limiting rings and the annular positioning platforms. A steel ball is movably disposed in each mounting hole for installation. An elastic element is fitted on the sliding section between the hole and the annular positioning platform. The sliding sleeve is slidably fitted on the sliding section and leaves a gap with the limiting section. The outer wall of the first insertion section is provided with a first annular groove. The first insertion section is inserted into the female connector near the first male connector. When the sliding sleeve slides, it can push the steel ball into the first annular groove. The outer wall of the fixed section is provided with a second annular groove. The fixed section is inserted into the female connector near the second male connector. When the sliding sleeve slides, it can push the steel ball into the second annular groove.

[0018] The beneficial effects of this solution are as follows: The design, which uses a sliding sleeve to push the steel ball into the annular groove, enables a "sliding engagement-sliding unlocking" one-handed operation mode for connecting the endotracheal tube to either the No. 1 or No. 2 male connector. During connection, simply insert the male connector into the female connector and push the sliding sleeve; the steel ball will automatically engage in the annular groove with the assistance of the elastic element. During disassembly, the sliding sleeve compresses the elastic element, disengaging the steel ball from the annular groove. No twisting or additional tools are required, significantly improving clinical assembly and disassembly efficiency, making it particularly suitable for rapid deployment in emergency treatment scenarios.

[0019] The elastic element stores elastic potential energy as the sliding sleeve slides, automatically resetting and maintaining the steel ball's locked state after the sleeve is released, preventing accidental unlocking due to accidental contact or vibration. This "locking-resetting" mechanical self-locking mechanism ensures that the connection remains stable during the periodic pressure changes of the balloon's inflation and deflation, making it more adaptable to dynamic treatment environments and reducing the risk of connection failure compared to traditional threaded connections.

[0020] Furthermore, a receiving groove is provided on the inner side wall of the sliding section, and a sealing ring is fixedly connected inside the receiving groove.

[0021] The beneficial effects of this solution are as follows: Due to the setting of the sealing ring, when the No. 1 or No. 2 male connector is inserted into the groove on the inner side wall of the sliding section, the sealing ring is tightly fitted with the outer side wall of the male connector, forming a physical sealing barrier, effectively blocking the gas leakage path and significantly improving the airtightness of the connection.

[0022] Furthermore, an annular sealing platform is fixedly connected to the outer wall of the second insertion section, and the outer diameter of the annular sealing platform is adapted to the inner diameter of the trachea.

[0023] The beneficial effects of this solution are as follows: The matching design of the outer diameter of the annular sealing platform and the inner diameter of the air pipe in this technical solution forms a tight interference fit when the air pipe is connected, effectively filling the annular gap between the air pipe and the No. 2 insertion section, avoiding lateral leakage of gas during transmission, significantly improving the airtightness of the connection part, and ensuring the pressure stability of the gas supply system.

[0024] Furthermore, a computer bracket is installed on the side of the counterpulsation bed, and a computer is mounted on the bracket.

[0025] The beneficial effects of this solution are as follows: Compared to mounting the computer stand at the end of the counterpulsation bed, side mounting significantly optimizes the clinical operating space and equipment layout. End mounting can easily cause medical staff to bump into the computer stand during operation, while side mounting allows the computer screen to maintain the optimal viewing angle with the operator, making it easier for medical staff to flexibly adjust their standing position on both sides of the bed and avoiding obstruction and space occupation during operation.

[0026] Furthermore, the computer bracket includes a support rod, a connecting cover, and a shielding cover connected in sequence. The connecting cover is located at the end of the support rod away from the counterpulsation bed and is used to install the computer. The shielding cover is located at the end of the connecting cover close to the counterpulsation bed. The computer's data cable can be connected to the computer in sequence through the support rod, the connecting cover, and the shielding cover. The shielding cover can cover the connection point between the data cable and the computer.

[0027] The beneficial effects of this solution are as follows: the support rod, connecting cover, and shielding cover form a closed cable channel, which neatly organizes the data cables that were originally scattered on the counterpulsation bed, avoiding the tangling of cables and airways on the counterpulsation bed, making the overall layout of the equipment more orderly, significantly improving the operating environment for medical staff. At the same time, the closed cable routing design reduces physical damage to data cables caused by friction, pulling, and stepping, effectively avoiding problems such as damage to the cable sheath and breakage of internal wires, extending the service life of data cables, and reducing equipment maintenance costs. The shielding cover can cover the connection points between the data cables and the computer, reducing the risk of short circuits or leakage caused by dust and liquid intrusion into the connection points, providing a safer operating environment for medical staff and patients.

[0041] like Figure 1 The external counterpulsation device shown includes a counterpulsation bed 1, an air supply system, and several sleeves 2.

[0042] like Figure 1 As shown, the counterpulsation bed 1 includes a bed frame 3, which serves as the basic support structure. A bed cover 4 is bolted to the top of the bed frame 3, and a mattress 5 is placed on top of the bed cover 4 to provide the patient with a comfortable treatment position. In addition, casters 6 are installed at the four corners of the bottom of the bed frame 3 to facilitate flexible movement and position adjustment of the device.

[0043] like Figure 1-2 As shown, a U-shaped fixing seat 7 is bolted to the bed frame 3 at the bottom of the bed cover 4. The U-shaped fixing seat 7 includes a base plate and side plates inclined on the left and right sides of the base plate. The lower end of the side plate is bolted to the base plate, and the upper end of the side plate is bolted to the bed frame 3. The space between the base plate and the bed cover 4 forms an outwardly expanding adjustment chamber 8, which facilitates the storage of the air tube 16 and avoids the problems of tangling and mess caused by the excessive length of the air tube 16. Side doors 9 are hinged to the bed frame 3 on both the front and rear sides of the U-shaped fixing seat 7. When the side doors 9 are closed, they can cover the internal air tube 16, improving the aesthetics of the counterpulsation bed 1; when opened, they allow direct access to the air tube 16, enabling quick inspection or replacement operations and optimizing maintenance convenience.

[0044] like Figure 2-3 As shown, the gas supply system includes a gas supply unit and a gas distribution mounting base. The gas distribution mounting base includes a distribution plate 10 and a mounting plate 11. The mounting plate 11 is bolted to the bottom of the base plate, and the distribution plate 10 is sealed to the bottom of the mounting plate 11. The bottom of the distribution plate 10 has three inflation / deflation ports 12. The top of the mounting plate 11 is equipped with several No. 2 male connectors 13, each of which is connected to the corresponding inflation / deflation port 12 at the bottom of the distribution plate 10, forming a gas transmission channel. The bottom of the U-shaped fixing base 7 has a No. 1 through hole corresponding to the No. 2 male connector 13, and the No. 2 male connector 13 can pass through the No. 1 through hole.

Both ends of the air tube 16 are equipped with female connectors 17. The female connector 17 at the lower end of the air tube 16 engages with the male connector 13. The female connector 17 at the upper end of the air tube 16 passes through the second through hole 14 and the third through hole 15 and extends to the top of the mattress 5, where it engages with the male connector 18 on the sleeve 2.

[0045] like Figure 4-6 As shown, each female connector 17 includes a second connecting nut 19, a second insertion tube, and a sliding sleeve 20. The second insertion tube, from top to bottom, consists of a sliding section 21, a limiting section 22, a third threaded section 23, and a second insertion section 24. The sliding section 21, limiting section 22, third threaded section 23, and second insertion section 24 are integrally formed. An annular limiting ring 25 is glued to the outer wall of the sliding section 21. Below the annular limiting ring 25, the sliding section 21 has four mounting holes along its circumference, and a steel ball 26 is movably disposed in each mounting hole. A receiving groove is formed on the inner wall of the sliding section 21 below the mounting holes, and a sealing ring 27 is glued to the receiving groove. Below the sealing ring 27, an annular positioning platform 28 is integrally formed on the outer wall of the sliding section 21, and an elastic element 29 is sleeved on the top of the sliding section 21 of the annular positioning platform 28. The sliding sleeve 20 is mounted on the sliding section 21 and maintains a distance from the limiting section 22. An annular pressing platform 30 is integrally formed on the inner wall of the sliding sleeve 20, and the limiting section 22 and the annular limiting ring 25 limit both ends of the sliding sleeve 20. An annular sealing platform 31 is integrally formed on the outer wall of the upper end of the second insertion section 24. The outer diameter of the annular sealing platform 31 matches the inner diameter of the air tube 16. When the air tube 16 is inserted into the second insertion section 24, the annular sealing platform 31 abuts against the inner wall of the air tube 16. The outer wall of the third threaded section 23 has external threads, and it is threadedly connected to the third threaded section 23 through the second connecting nut 19, clamping the air tube 16 between the second connecting nut 19 and the annular sealing platform 31. In this embodiment, the elastic element 29 is a compression spring.

[0046] like Figure 5As shown, a connecting tube 32 is glued to the bottom of the bladder sleeve 2. The connecting tube 32 is I-shaped and communicates with the inner cavity of the bladder sleeve 2. A first connecting male connector 18 is connected to the lower end of the connecting tube 32. The first connecting male connector 18 includes a first connecting nut 33 and a first insertion tube. The first insertion tube consists of a first threaded section 34 and a first insertion section 35 from top to bottom. The first threaded section 34 and the first insertion section 35 are integrally formed. The outer wall of the first threaded section 34 has external threads. The first threaded section 34 is threadedly connected to the first connecting nut 33. The connecting tube 32 is fixed to the first threaded section 34 by the first connecting nut 33. The outer wall of the first insertion section 35 is smooth and has a first annular groove. When the connecting female connector 17 at the upper end of the air tube 16 is connected to the first connecting male connector 18, the steel ball 26 in the connecting female connector 17 can be inserted into the first annular groove. At the same time, the sealing ring 27 abuts against the outer wall of the first insertion section 35 to achieve a seal. During disassembly, slide the sliding sleeve 20 downwards to compress the elastic element 29, release the constraint of the annular pressing table 30 on the steel ball 26, and then remove the connecting female head 17. After releasing the sliding sleeve 20, the sliding sleeve 20 will return to its original position under the action of the compression spring.

[0047] like Figure 7-8 As shown, the second male connector 13 consists of a fixed section 36, a positioning section 37, and a second threaded section 38 from top to bottom. The fixed section 36, positioning section 37, and second threaded section 38 are integrally formed. The second threaded section 38 is threadedly connected to the mounting plate 11. The outer wall of the fixed section 36 has a second annular groove 39. When the female connector 17 at the lower end of the air pipe 16 is connected to the second male connector 13, the steel ball 26 inside the female connector is engaged in the second annular groove 39, and the sealing ring 27 abuts against the outer wall of the fixed section 36 for a tight seal. For disassembly, sliding the sliding sleeve 20 upwards compresses the spring, releasing the constraint of the annular pressing platform 30 on the steel ball 26, allowing separation. After releasing the sliding sleeve 20, the structure returns to its original position.

[0048] like Figure 1 As shown, the gas supply unit includes a compressor 40, a first gas storage tank 41, and a second gas storage tank 42. The compressor 40, the first gas storage tank 41, and the second gas storage tank 42 are all bolted to the bed frame 3 below the diverter plate 10. The outlet of the compressor 40 is connected to the first gas storage tank 41 through a pipe. The first gas storage tank 41 is connected to the second gas storage tank 42 through a pipe. The second gas storage tank 42 is connected to three gas supply pipes 43. The three gas supply pipes 43 are respectively connected to three charging and discharging ports 12 at the bottom of the diverter plate 10. Each gas supply pipe 43 is equipped with a two-way solenoid valve to control the charging and discharging of gas.

[0049] like Figure 1 and Figure 9-10As shown, a computer bracket 44 is bolted to the rear side of the bed frame 3, and a computer 45 is mounted on the computer bracket 44. The computer bracket 44 can conceal the connection cable of the computer 45. Specifically, the computer bracket 44 includes a support rod 46, a rotating joint 47, and a connecting cover 48. Both the support rod 46 and the rotating joint 47 are hollow structures, and the support rod 46, the rotating joint 47, and the connecting cover 48 are connected in sequence. The lower end of the support rod 46 is bolted to the bed frame 3. An annular limiting groove 49 is provided on the outer side wall of the upper end of the support rod 46. A limiting block 50 is glued into the annular limiting groove 49. The rotating joint 47 is rotatably connected to the upper end of the support rod 46. A limiting screw 51 is threaded onto the rotating joint 47. The limiting screw 51 passes through the rotating joint 47 and abuts against the annular limiting groove 49. Due to the setting of the limiting block 50, the rotation angle of the rotating joint 47 can be limited, preventing the data cable from twisting or being squeezed. The left side of the connecting cover 48 is bolted to... A connecting base 52 is provided, and a rotating connector 47 is rotatably connected to the connecting base 52 via a rotating shaft. Arc-shaped holes 53 are provided on both the front and rear sides of the connecting base 52. Locking bolts 54 are threaded onto both the front and rear sides of the rotating connector 47. A fixing nut 55 is threaded onto one end of the locking bolt that passes through the arc-shaped hole 53. A connecting cover 48 is bolted to the left side of the computer 45. A shielding cover 56 is bolted to the bottom of the connecting cover 48. The connecting cover 48 and the shielding cover 56 are connected, and the shielding cover 56 can cover the connection point between the data cable and the computer 45. When installing the computer 45, the data cable is first passed through the support rod 46, rotating connector 47, connecting cover 48, and shielding cover 56 in sequence to connect to the computer 45. Then, the connecting cover 48 is installed on the computer 45. Finally, the support rod 46 is fixed to the bed frame 3. This method can hide the data cable, prevent it from tangling with the airbag connecting tube 32, make the equipment layout neat, and improve the operating environment for medical staff. Meanwhile, the enclosed cable management design reduces physical damage to data cables caused by friction, pulling, and stepping, extending their lifespan and reducing equipment maintenance costs. Furthermore, medical personnel can adjust the horizontal angle of the computer 45 using the limiting screw 51 and the annular limiting groove 49, and adjust the tilt angle by rotating the connecting seat 52. This allows the computer screen 45 to move flexibly in both horizontal and vertical dimensions, enabling them to adjust the screen to the optimal viewing angle according to their height, posture, or operating habits, thus alleviating visual fatigue and physical discomfort caused by prolonged operation.
