Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an external counterpulsation device. Background Art

[0002] As a key device for auxiliary treatment of cardiovascular diseases, the structural design of the external counterpulsation device directly affects the treatment effect and patient safety. The existing device is mainly composed of an air supply system, a control system, a monitoring system, a counterpulsation bed and a bag cuff assembly, and each part works together to achieve the treatment function. Specifically, the bag cuff is set on the top of the counterpulsation bed, and the No. 1 male connector installed on it is connected to the air supply system through a trachea; the air supply system includes an air supply unit and a gas diversion connection seat, and the gas diversion connection seat is fixed under the bed cover of the counterpulsation bed. A number of No. 2 male connectors are provided on the side close to the bed cover. The bed cover and mattress of the counterpulsation bed are provided with through holes, and the connectors are located in the through holes. Both ends of the trachea are provided with female connectors, and the two female connectors are respectively threaded with the No. 1 male connector and the No. 2 male connector. The air supply unit is installed on the gas diversion connection seat and is responsible for completing the inflation and deflation operation of the bag cuff. During the treatment process, the control system accurately controls the inflation and deflation timing of the bag cuff based on the patient's electrocardiogram signals and other physiological parameters collected in real time by the monitoring system, providing a guarantee for the safety and effectiveness of the treatment. However, this technical solution has significant defects in actual application: on the one hand, an extended trachea design is adopted to adapt to patients of different body sizes, but the gas diversion connector is fixed to the structure at the bottom of the counterpulsation bed, which causes the No. 2 male connector to be too close to the patient's body. When the cuff is inflated, the lifting force generated by the gas filling in the trachea can easily cause the body of lighter patients to detach from the mattress, resulting in unstable physical condition during treatment; on the other hand, threaded connections are adopted between the cuff and the trachea, and between the trachea and the gas diversion connector. In clinical operations, repeated twisting is required to complete disassembly and assembly, which is not only cumbersome and time-consuming, but also prone to loose connection due to thread wear after long-term use, causing gas leakage, which in turn affects the inflation and deflation accuracy of the cuff, posing a threat to the treatment effect and equipment reliability. Summary of the invention

[0003] The present invention aims to provide an extracorporeal counterpulsation device to solve the problem in the prior art that the gas shunt connection seat is fixed to the bottom of the counterpulsation bed, causing the No. 2 connecting male head to be close to the patient's body, thereby causing body instability during treatment, while improving the defects of cumbersome assembly and disassembly of the threaded connection and easy leakage.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an external counterpulsation device, comprising a counterpulsation bed, an air supply system and a plurality of trachea, wherein a U-shaped fixing seat is fixedly connected under the bed cover of the counterpulsation bed; a plurality of bag sleeves are arranged on the top of the counterpulsation bed, and a No. 1 connecting male head is installed on each bag sleeve; the air supply system comprises a gas diversion connecting seat and a gas supply unit, the gas diversion connecting seat is fixedly connected under the U-shaped fixing seat, a plurality of No. 2 connecting male heads are installed on the side of the gas diversion connecting seat close to the U-shaped fixing seat, a No. 1 through hole corresponding to the connecting head is arranged on the U-shaped fixing seat, a connecting female head is installed at both ends of the trachea, the No. 2 connecting male head is snap-fitted with the connecting female head at one end of the trachea, and the connecting female head at the other end of the trachea passes through the counterpulsation bed and is snap-fitted with the No. 1 connecting male head; the air supply unit is installed on the gas diversion connecting seat, and can realize the function of inflating and discharging the gas in the bag sleeve.

[0005] The beneficial effects of this solution are as follows: This technical solution achieves device performance upgrades through structural innovation and connection method optimization: First, it focuses on strengthening treatment stability and safety. In view of the problem that the existing device has the gas shunt connection seat fixed under the bed cover of the counterpulsation bed, resulting in the No. 2 male connector being close to the patient and the tracheal inflation lifting force easily causing the body of a lighter patient to leave the mattress, this solution adds a U-shaped fixing seat to the bottom of the counterpulsation bed and moves the gas shunt connection seat down and fixes it to its bottom. By adjusting the chamber to change the conduction path of the tracheal lifting force, the force generated by gas filling can be effectively dispersed, and the patient's body lifting displacement can be greatly reduced, eliminating the monitoring signal fluctuations and accidental risks caused by body shaking from the root, significantly improving the safety and comfort of treatment. Secondly, it improves the stability of treatment effects and maintenance efficiency. The use of snap-on connections instead of traditional threaded connections allows the trachea to be quickly disassembled and assembled without twisting, greatly shortening clinical maintenance time and improving disassembly and assembly efficiency. This technical solution achieves a tight fit through mechanical snap-on connections, avoiding the loosening of threaded connections due to long-term wear, eliminating the risk of gas leakage from a structural design perspective, ensuring the sealing and stability of the gas supply system, and thus ensuring that the therapeutic effect of the external counterpulsation device is not affected by the wear of connecting components. In addition, no additional tools are required during the operation, reducing the difficulty of maintenance, providing convenience for rapid clinical replacement of cuffs or inspection of trachea, and further enhancing the reliability and safety of equipment use.

[0006] Furthermore, the U-shaped fixing seat includes a bottom plate and side plates obliquely arranged on opposite sides of the bottom plate, the lower end of the side plate is fixedly connected to the bottom plate, the upper end of the side plate is fixedly connected to the counterpulsation bed, and the space between the counterpulsation bed and the bottom plate forms an outward-expanding adjustment chamber.

[0007] The beneficial effects of this solution are as follows: In response to the problem of tracheal storage caused by the elongated tracheal tube design in existing devices, the adjustment chamber formed by the bottom plate and the counterpulsation bed in this solution provides a dedicated storage space for the long tracheal tube. Medical staff can flexibly adjust the length of the tracheal tube pulled out in the adjustment chamber according to the actual body shape 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 overly long tracheal tube, achieving efficient adaptation of the device to patient groups with different heights and body shapes and significantly improving the clinical practicability of the device.

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

[0009] Furthermore, the air supply unit includes a compressor, a first air storage tank, and a second air storage tank. The air outlet of the compressor is connected to the first air storage tank, the first air storage tank is connected to the second air storage tank, and a number of air supply pipes are connected to the second air storage tank. A number of air charging and discharging ports are provided at the bottom of the gas distribution connection seat. The air supply pipes and the air charging and discharging ports correspond to each other and are connected to each other. A two-way solenoid valve is installed on each air supply pipe to control the charging and discharging of gas.

[0010] The beneficial effects of this solution are as follows: The air supply unit adopts a combined design of "compressor + double air storage tanks + two-way solenoid valve". The compressor continuously supplies gas to the first air storage tank, which is then delivered to the second air storage tank after being stabilized in pressure by the first air storage tank to form a stable air pressure source. When the two-way solenoid valve is opened, the compressed air in the second air storage tank quickly fills the bladder sleeve through the air supply pipe to achieve precise inflation; when it is opened in the reverse direction, the gas in the bladder sleeve is discharged through the two-way solenoid valve.

[0011] Furthermore, a connecting pipe is fixedly connected to the bladder sleeve and is in communication with the inner cavity of the bladder sleeve. The first connecting male head includes a first connecting nut and a first insertion pipe. The first insertion pipe includes a first threaded section and a first insertion section connected in sequence. The outer wall of the first threaded section is provided with an external thread, and the first threaded section is threadedly connected to the first connecting nut. The connecting pipe is fixed to the first threaded section through the first connecting nut. The first insertion section is inserted into the connecting female head and is in snap-fit connection with the connecting female head.

[0012] The beneficial effects of this solution are as follows: Through the split design of the connecting pipe and the first connecting male head, this technical solution ensures the sealing effect while achieving the quick connection between the bladder sleeve and the first connecting male head; the clamping method between the first insertion section and the connecting female head can quickly complete the installation and disassembly operations of the two. When the bladder sleeve needs to be replaced, only the clamped part needs to be separated to quickly disassemble the connection between the trachea and the bladder sleeve, without removing the entire connection assembly, significantly improving the clinical use efficiency. In addition, while simplifying the operation steps, the clamping method provides a stable connection force through mechanical clamping, effectively ensuring the safety during clinical use.

[0013] Furthermore, each second connecting male head is connected to the corresponding air charging and discharging port. The second connecting male head includes a fixed section, a positioning section, and a second threaded section connected in sequence. The second threaded section is threadedly connected to the gas distribution connection seat. The fixed section is inserted into the connecting female head and is in clamping cooperation with the connecting female head.

[0014] The beneficial effects of this solution are as follows: Through the segmented design of the fixed section, the positioning section, and the second threaded section, this technical solution realizes the optimization of the functional partition of the connection structure. The clamping cooperation between the fixed section and the connecting female head can quickly complete the disassembly and assembly of the trachea and the gas distribution connection seat, significantly improving the operation efficiency; the threaded connection between the second threaded section and the gas distribution connection seat ensures the stability of the second connecting male head on the gas distribution connection seat.

[0015] Furthermore, each connecting female head includes a second connecting nut, a second insertion pipe, and a sliding sleeve. The second insertion pipe includes a sliding section, a limiting section, a third threaded section, and a second insertion section connected in sequence. The trachea is inserted into the second insertion section and is fixed by the threaded connection between the second connecting nut and the third threaded section; annular limiting rings and annular positioning platforms are arranged at intervals on the sliding section. On the sliding section between the annular limiting ring and the annular positioning platform, a number of installation holes are provided along its circumferential direction. A steel ball is movably arranged in each installation hole. An elastic member is sleeved on the sliding section between the installation hole and the annular positioning platform. The sliding sleeve is slidably sleeved on the sliding section and has a spacing from the limiting section. A first annular clamping groove is provided on the outer side wall of the first insertion section. The first insertion section is inserted into the connecting female head near one end of the first connecting male head. When the sliding sleeve slides, it can push the steel ball into the first annular clamping groove; a second annular clamping groove is provided on the outer side wall of the fixed section. The fixed section is inserted into the connecting female head near one end of the second connecting male head. When the sliding sleeve slides, it can push the steel ball into the second annular clamping groove.

[0016] The beneficial effects of this solution are as follows: Through the design of the sliding sleeve sliding to push the steel ball into the annular groove, a single-handed operation mode of "sliding engagement - sliding unlocking" between the trachea and the first male connector or the second male connector is achieved. When connecting, simply insert the male connector into the female connector and push the sliding sleeve, and the steel ball can automatically snap into the annular groove with the assistance of the elastic component; when disassembling, slide the sliding sleeve to compress the elastic component to disengage the steel ball from the annular groove, without the need for screwing or additional tools, significantly improving the clinical disassembly and assembly efficiency, especially suitable for rapid deployment in emergency treatment scenarios.

[0017] The elastic component stores elastic potential energy when the sliding sleeve slides, and automatically resets after releasing the sliding sleeve to maintain the clamping state of the steel ball, avoiding accidental unlocking caused by accidental touch or vibration. This mechanical self-locking mechanism of "clamping - resetting" ensures that the connection part always remains stable during the periodic pressure changes of the inflation and deflation of the balloon sleeve, and can better adapt to the dynamic treatment environment compared with traditional threaded connections, reducing the risk of connection failure.

[0018] Furthermore, a receiving groove is provided on the inner side wall of the sliding section, and a sealing ring is fixedly connected in the receiving groove.

[0019] The beneficial effects of this solution are as follows: Due to the setting of the sealing ring in this technical solution, when the first male connector or the second male connector is inserted, the sealing ring in the receiving groove on the inner side wall of the sliding section closely fits 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 part.

[0020] Furthermore, an annular sealing platform is fixedly connected to the outer side wall of the second plugging section, and the outer diameter of the annular sealing platform is adapted to the inner diameter of the trachea.

[0021] The beneficial effects of this solution are as follows: The adaptation design of the outer diameter of the annular sealing platform to the inner diameter of the trachea in this technical solution forms a tight interference fit when the trachea is sleeved, effectively filling the annular gap between the trachea and the second plugging 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.

[0022] Furthermore, a computer bracket is installed on the side of the counterpulsation bed, and a computer is installed on the computer bracket.

[0023] The beneficial effects of this solution are as follows: Compared with installing the computer bracket at the end of the counterpulsation bed, installing it on the side can significantly optimize the clinical operation space and equipment layout. Installing it at the end easily causes the medical staff's body to collide with the computer bracket during operation, while installing it on the side can keep the computer screen at the best viewing angle with the operator, facilitating the medical staff to flexibly adjust their standing positions on both sides of the bed body, avoiding operation obstruction and space occupation.

[0024] Further, the computer support includes a support rod, a connection cover, and a shielding cover that are connected in sequence. The connection cover is provided at one end of the support rod away from the counterpulsation bed, and the connection cover is used to install the computer. The shielding cover is provided at one end of the connection cover close to the counterpulsation bed. The data cable of the computer can be connected to the computer through the support rod, the connection cover, and the shielding cover in sequence, and the shielding cover can cover the connection part between the data cable and the computer.

[0025] The beneficial effects of this solution are as follows: The support rod, the connection cover, and the shielding cover form a closed cable channel, which orderly houses the data cables that were originally scattered on the counterpulsation bed, avoiding the entanglement of cables and air tubes on the counterpulsation bed, making the overall layout of the equipment more regular, significantly improving the operation environment of medical staff. At the same time, the closed wiring design reduces physical damage to the data cables caused by friction, pulling, trampling, etc., effectively avoiding problems such as cable outer skin damage and internal wire breakage, extending the service life of the data cables, reducing the equipment maintenance cost. The shielding cover can cover the connection part between the data cable and the computer, reducing the potential short - circuit or leakage hazards caused by dust and liquid intrusion into the connection part, providing a safer use environment for medical staff and patients.

[0032] As Figure 4-6 As shown in the figure, each connecting female head 17 includes a second connecting nut 19, a second insertion pipe and a sliding sleeve 20. The second insertion pipe is successively a sliding section 21, a limiting section 22, a third threaded section 23 and a second insertion section 24 from top to bottom. The sliding section 21, the limiting section 22, the third threaded section 23 and the second insertion section 24 are integrally formed. An annular limiting ring 25 is adhesively connected to the outer side wall of the sliding section 21. Four mounting holes are opened in the circumferential direction of the sliding section 21 below the annular limiting ring 25. A steel ball 26 is movably arranged in each mounting hole. A receiving groove is opened on the inner side wall of the sliding section 21 below the mounting hole, and a sealing ring 27 is adhesively connected in the receiving groove.

The connecting pipe 32 is fixed on the first threaded section 34 through the first connecting nut 33. The outer side wall of the first inserting section 35 is smooth and is provided with a first annular clamping groove. When the connecting female head 17 at the upper end of the air pipe 16 is connected to the first connecting male head 18, the steel ball 26 in the connecting female head 17 can be clamped into the first annular clamping groove, and at the same time, the sealing ring 27 abuts against the outer side wall of the first inserting section 35 to achieve sealing. During disassembly, the sliding sleeve 20 is slid downward to compress the elastic member 29, and the constraint of the annular pressing platform 30 on the steel ball 26 is released, so that the connecting female head 17 can be removed. After the sliding sleeve 20 is released, the sliding sleeve 20 resets under the action of the compression spring. As Figure 7-8 shown, the second connecting male head 13 is, from top to bottom, a fixing section 36, a positioning section 37 and a second threaded section 38.

During disassembly, the sliding sleeve 20 is slid upward to compress the compression spring, and the constraint of the annular pressing platform 30 on the steel ball 26 is released to separate them. After the sliding sleeve 20 is released, the structure resets.

[0034] As Figure 1 shown, the air 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 installed on the bed frame 3 below the flow dividing plate 10 through bolts.

A two-way solenoid valve is installed on each air supply pipe 43 to control the charging and discharging of gas.

[0035] As Figure 1 and Figure 9-10As shown in the figure, a computer bracket 44 is installed at the rear side of the bed frame 3 through bolts. A computer 45 is installed on the computer bracket 44, and the computer bracket 44 can hide the connecting line of the computer 45. Specifically, the computer bracket 44 includes a support rod 46, a rotating joint 47 and a connecting cover 48.

Due to the setting of the limiting block 50, the rotation angle of the rotating joint 47 can be limited, avoiding the twisting or extrusion of the data cable. A connecting seat 52 is connected to the left side surface of the connecting cover 48 through bolts. The rotating joint 47 is rotatably connected to the connecting seat 52 through a rotating shaft. Arc-shaped holes 53 are formed on both the front and rear sides of the connecting seat 52. Locking bolts 54 are threadedly connected to both the front and rear sides of the rotating joint 47. One end of the locking bolt passing through the arc-shaped hole 53 is threadedly connected with a fixing nut 55; the connecting cover 48 is installed on the left side surface of the computer 45 through bolts. A shielding cover 56 is installed below the connecting cover 48 through bolts. The connecting cover 48 is communicated with the shielding cover 56, and the shielding cover 56 can cover the connection part of the data cable and the computer 45. When installing the computer 45, first pass the data cable through the support rod 46, the rotating joint 47, the connecting cover 48 and the shielding cover 56 in sequence and connect it to the computer 45, then install the connecting cover 48 on the computer 45, and finally fix the support rod 46 on the bed frame 3, which can hide the data cable, avoid winding with the airbag connecting pipe 32, make the equipment layout regular, and improve the operation environment of medical staff. At the same time, the closed wiring design reduces the physical damage of the data cable caused by friction, pulling, trampling, etc., extends its service life, and reduces the equipment maintenance cost. In addition, medical staff can adjust the horizontal angle of the computer 45 through the cooperation of the limiting screw 51 and the annular limiting groove 49, and adjust the pitching angle by rotating the connecting seat 52, so that the computer 45 screen can flexibly change in both the horizontal and vertical dimensions, so as to adjust the screen to the best viewing angle according to their own height, sitting posture or operation habits, and relieve the visual fatigue and physical discomfort caused by long-term operation.
