Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a ventricular assist system host. Background Technology

[0002] Ventricular assist devices (VADs) are primarily used in percutaneous coronary intervention (PCI) to provide cardiac pumping function for patients with heart failure, helping their hearts to quickly return to normal circulatory support. The VAD pumps blood from the left ventricle into the aorta, and then distributes it throughout the body via systemic circulation. VADs require a main unit or controller to manage their operating parameters and display their status to achieve effective blood pumping assistance. The main unit of the VAD system includes various interfaces for connecting accessories, infusion set mounting points, and displays for parameters and physiological signals. The proper placement of these components is crucial for both the effectiveness of the VAD and its overall aesthetics. Utility Model Content

[0003] The purpose of this invention is to provide a ventricular assist system host that can improve flushing effect and has a reasonable layout.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a ventricular assist system host, including a housing, a main control module is provided in the inner cavity of the housing, a display and an infusion set mounting position are provided at the front of the housing, the infusion set mounting position includes a slot arranged vertically, the shape of the slot matches the shape of the infusion set housing, a drive shaft is provided at the bottom of the slot protruding into the cavity, the drive shaft cooperates with a coupling provided on the infusion set housing to drive the piston movement inside the infusion set housing.

[0005] Furthermore, a recessed part is provided on the side of the display box, which is arranged vertically. The slot is located on the upper part of the recessed part. The upper and lower cavity walls of the recessed part are respectively provided with slots for holding the infusion set inlet tube and outlet tube. A cover plate is hinged to one vertical side of the recessed part, and a locking structure that cooperates with the locking tongue on the cover plate is provided on the other vertical side.

[0006] Furthermore, the enclosure includes a main enclosure and a side enclosure located on one side of the main enclosure. The main control module is located inside the main enclosure, the display is located at the front of the main enclosure, the infusion set mounting position is located at the front of the side enclosure, a motor is located inside the side enclosure, the front surface of the side enclosure above and below the recess is arc-shaped, and the bottom of the side enclosure is higher than the bottom of the main enclosure, while the top of the side enclosure is lower than the top of the main enclosure.

[0007] Furthermore, a photoelectric composite cable interface is provided on the side wall of the side enclosure, and a cover is provided on the photoelectric composite cable interface. The cover is hinged to the side wall of the enclosure via a shaft. The spring force drives the cover to rotate around the shaft to the blocking position of the photoelectric composite cable interface, or an external force overcomes the spring force to drive the cover to rotate around the shaft to the exposed clearance position of the photoelectric composite cable interface.

[0008] Furthermore, the side wall of the main body is provided with a groove, in which a switch, power cord interface and various parallel ports are provided, and a baffle that forms an openable connection with the side of the groove is provided at the groove opening.

[0009] Furthermore, a spare control knob is provided on the side wall of the upper part of the groove.

[0010] Furthermore, a clamping plate is provided on the back of the main body. One side of the clamping plate is rotated with the main body via a pivot. The spring force drives the clamping plate to fit tightly against the back of the body. External force overcomes the spring force and drives the clamping plate to rotate around the pivot. Rubber pads are also provided at the clamping plate position and on the body surface below the clamping plate.

[0011] Furthermore, the clamping plate is U-shaped, and the back of the box has an annular recess that matches the shape of the clamping plate. A grounding post is also provided on the back of the box.

[0012] Furthermore, ventilation grilles are provided on the upper and bottom of the back of the main body, and a handle is provided on the top of the main body.

[0013] In the above scheme, the infusion set installation position is arranged vertically as a whole. This vertical arrangement is not a completely vertical arrangement, but a roughly vertical arrangement with a small angle to the vertical direction. This is related to the degree of inclination of the front surface of the box. In this way, when the infusion set is placed in the slot, the piston cylinder of the infusion set is also arranged roughly vertically as a whole. Therefore, it is beneficial to ventilate the air bubbles in the infusion set. At the same time, the resistance to liquid flow is reduced, the liquid delivery is smoother, the cleaning effect on the ventricular assist device is better, and the auxiliary effect of the entire ventricular assist system is improved.

[0020] like Figures 1-6 As shown, a ventricular assist system main unit includes a housing 10. A main control module (not shown) is housed within the housing 10. A display 20 and an infusion set mounting position 30 are located at the front of the housing 10. The display 20 has a touchscreen function, enabling human-computer interaction for selecting and inputting control parameters. Simultaneously, the screen of the display 20 can display real-time operating parameters of the ventricular assist device and the patient's physiological information. The infusion set mounting position 30 includes a vertically arranged slot 31, the shape of which matches the shape of the infusion set housing. A drive shaft 32 protrudes from the bottom of the slot 31 into the cavity, and the drive shaft 32 cooperates with a coupling on the infusion set housing to drive the piston movement within the infusion set housing.

[0021] In existing designs, the infusion set mounting position 30 is mostly located at the front of the housing 10, below the display 20, and is placed horizontally. This means the piston cylinder of the infusion set is horizontally positioned. This placement is not conducive to the evacuation of air bubbles from the infusion set, and the infusion outlet tube needs to extend through a winding loop to the bottom of the main unit, which inevitably leads to greater resistance to fluid flow and is detrimental to fluid delivery. In this application, the infusion set mounting position 30 is arranged vertically. This vertical arrangement is not a completely vertical direction, but rather a roughly vertical direction with a small angle to the vertical direction. This is related to the inclination of the front surface of the housing 10. Thus, when the infusion set is placed in the slot 31, the piston cylinder of the infusion set is also roughly vertical, which is beneficial for evacuating air bubbles from the infusion set. At the same time, the infusion outlet tube extends directly to the bottom of the main unit, thus reducing fluid flow resistance, making fluid delivery smoother, improving the cleaning effect on the ventricular assist device, and enhancing the overall assistive effect of the ventricular assist system.

[0022] Furthermore, a vertically oriented recess 33 is provided on the housing 10 beside the display 20. The slot 31 is located in the upper part of the recess 33, and the inner cavity of the recess 33 below the slot 31 is used to accommodate a section of the outlet tube. For some infusion sets, a sensing component for measuring liquid pressure (not shown in the figure) is provided on the outlet tube. In this case, a slot-like structure can be provided in the cavity of the recess 33 to hold and fix the sensing component. The upper and lower cavity walls of the recess 33 are respectively provided with tube grooves 34 for holding the infusion set's inlet and outlet tubes. A cover plate 35 is hinged to one vertical side of the recess 33, and a locking structure 36 that engages with the locking tongue on the cover plate 35 is provided on the other vertical side. Under normal circumstances, the cover plate 35 covers the recess 33, giving the main unit a beautiful and elegant appearance. When the infusion set is needed, the cover plate 35 is opened to expose the recess 33, and then the infusion set is inserted into the slot 31. At this time, the coupling on the infusion set is precisely connected to the drive shaft 32. When the motor 40 rotates, it can drive the piston inside the infusion set to pump the liquid. The infusion set's inlet tube and infusion tube pass through the tube groove 34. Preferably, the tube groove 34 continues to extend vertically towards the front surface of the housing 10. This way, after the infusion set is placed in position, the cover plate 35 can be closed without affecting the liquid delivery, and the inlet tube and infusion tube can also be limited.

[0023] As a preferred embodiment of this utility model, the housing 10 includes a main housing 11 and a side housing 12 disposed on one side of the main housing 11. The main control module is disposed inside the main housing 11, the display 20 is disposed at the front of the main housing 11, and the infusion set mounting position 30 is also disposed at the front of the side housing 12. A motor 40 is disposed inside the side housing 12. The front surface of the side housing 12 above and below the recess 33 is arc-shaped, and the inlet pipe and infusion pipe extend along the arc-shaped surface, which will not interfere with the closing of the cover 35, and the design is aesthetically pleasing. Furthermore, the bottom of the side housing 12 is higher than the bottom of the main housing 11, and the top of the side housing 12 is lower than the top of the main housing 11. Here, the main housing 11 and the side housing 12 are separated by a partition, so the motor 40 inside the side housing 12 will not generate electromagnetic interference to the main control module, and the heat emitted by the motor 40 during operation will not affect the main control module, thereby ensuring the stability and safety of the main control module.

[0024] For connection to the ventricular assist device, a photoelectric composite cable interface 121 is provided on the side wall of the side housing 12. A cover 122 is provided on the photoelectric composite cable interface 121. The cover 122 is hinged to the side wall of the housing 12 via a shaft 123. A spring force drives the cover 122 to rotate around the shaft 123 to the position where it blocks the photoelectric composite cable interface 121, or an external force overcomes the spring force to drive the cover 122 to rotate around the shaft 123 to the exposed position where the photoelectric composite cable interface 121 is exposed. Integrating the power cable interface and the fiber optic cable interface into one interface not only optimizes the structure of the ventricular assist device but also reduces the number of interfaces and operation time. When not in use, the cover 122 covers the photoelectric composite cable interface 121 to protect the interface and prevent dust from entering. When in use, the cover 122 is rotated by hand to expose the photoelectric composite cable interface 121, and the connector of the ventricular assist device can be inserted.

[0025] The main enclosure 11 has a groove 111 on its side wall, which houses a switch, a power cord interface, and various parallel ports. A baffle 112, which opens and closes with the side of the groove, is located at the groove opening. The interface directly connected to the ventricular assist device—the photoelectric composite cable interface 121—is located on one side of the enclosure 10, while interfaces not directly connected to the ventricular assist device (switch, power cord interface, and various parallel ports) are located on the other side of the enclosure 10. This design avoids wiring confusion and further improves the overall system safety.

[0026] The monitor 20 in the main unit has a touch screen function. To further improve the safety performance of the entire device, a spare control knob 113 is provided on the side wall of the upper part of the recess 111. In case the touch screen function of the monitor 20 malfunctions, the control knob 113 can be used to select options, providing double protection and higher safety performance.

[0027] In some usage scenarios, the main unit needs to be placed on a trolley. In order to fix the main unit to the trolley, we provide a clamping plate 114 on the back of the main housing 11. One side of the clamping plate 114 is rotated with the main housing 11 via a pivot. The spring force drives the clamping plate 114 to fit tightly against the back of the main housing 11. External force overcomes the spring force and drives the clamping plate 114 to rotate around the pivot. Rubber pads 115 are also provided at the position of the clamping plate 114 and on the surface of the main housing 11 below the clamping plate 114. When not in use, the clamp 114 is pressed against the back of the main housing 11 by the spring force. When it is necessary to fix the main unit to the trolley, the clamp 114 is rotated around the pivot to lock the clamp 114 in a specific position on the trolley. Then the clamp 114 is released and the clamp 114 is clamped to the trolley by the spring force to achieve fixation. In order to prevent the trolley from damaging the surface of the main housing 11, a rubber pad 115 is provided for isolation and protection. The rubber pad 115 is preferably made of hard material, which can not only protect the main housing 11, but also increase the stability of the main unit.

[0028] Furthermore, the clamping plate 114 is U-shaped, and the back of the main housing 11 is provided with an annular recess 116 that matches the shape of the clamping plate 114. A grounding post 117 is also provided on the back of the housing 11. In this way, under normal conditions, the clamping plate 114 is fitted into the annular recess 116 and is flush with the back of the main housing 11. In order to facilitate gripping the clamping plate 114, an auxiliary recess can be extended at a suitable position in the annular recess 116 to facilitate finger insertion.

[0029] Furthermore, the upper and lower back of the main enclosure 11 are equipped with heat dissipation grilles to dissipate heat in a timely manner and ensure the normal operation of the host. If necessary, a cooling fan can be added inside the main enclosure 11. To facilitate the movement of the enclosure 10, a handle 118 is provided on the top of the main enclosure 11. The host can be easily moved by holding the handle 118.
