TECHNICAL AREA

[0002] Currently, due to the separate design of the blood pump catheter and control unit, timely communication between the pump catheter and control unit is necessary during operation of the ventricular assist device (VAD) to ensure proper functioning. This allows the control unit to transmit control signals to the blood pump catheter via a communication channel, thereby controlling its operation within the body. Simultaneously, for closed-loop control, the blood pump catheter also requires the communication channel to transmit physiological data from the body to the control unit. This facilitates the transmission of more precise control signals from the control unit to the blood pump catheter.

[0003] In this technology, various ventricular assist devices (VADs) utilize blood pump catheters with different communication types. To meet the control requirements of these catheters, control units with various interfaces for different communication types must be developed. However, a single control unit has limited adaptability to different blood pump catheters, meaning it cannot simultaneously meet the communication requirements of catheters with multiple communication types and functions. Therefore, there is an urgent need for a control unit that integrates both a VAD and a VAD itself. DISCLOSURE OF THE USE PATTERN

[0020] The features and exemplary embodiments of the various aspects of the present application are described in detail below. To present the objectives, technical solutions, and advantages of the present application more clearly and comprehensibly, a further detailed description of the present application is given below with reference to the drawings and specific embodiments. It is understood that the specific embodiments described here serve only to illustrate the present application and are not intended to limit it. For those skilled in the art, the present application can also be implemented without considering some of these specific details. The following description of the embodiments serves only to provide a better understanding of the present application by illustrating examples from the present application.It should be noted that relational terms such as "first" and "second" are used here merely to distinguish one entity or operation from another, without necessarily requiring or implying any actual relationship or order between these entities or operations. Furthermore, the terms "inclusive," "comprehensive," or other variations thereof are intended to denote non-exclusive inclusion.

Without further limitation, a term described as "comprehensive"...“The defined element does not imply that there are other identical elements in the process, procedure, object or device containing that element.”

[0021] In the technology in question, due to the currently simple communication and control logic of the blood pump catheter, communication between the control unit and the blood pump catheter can be achieved solely through an electrical interface. However, with technological advancements, the electrical interface may become incompatible with some more complex control logics due to limitations in transmission speed and the influence of electromagnetic interference. This could prevent the implementation of some more complex blood pump catheter control logics. Furthermore, with the technological progress in the future development of ventricular assist devices (VADs), communication via an electrical interface alone will no longer be sufficient to meet the control and communication requirements of future VADs.Currently, optical communication is the predominant communication method. Therefore, future development of ventricular assist devices (VADs) will also require corresponding optical communication capabilities. To adapt to future developments, VADs that currently only have electrical interfaces must be supplemented with optical communication interfaces. This is the only way to meet the requirements for optical communication. However, adding these optical communication interfaces may necessitate the parallel production of several variants of the VAD control unit. This means that a single control unit would not be able to meet the diverse communication requirements of the various types and functions of blood pump catheters available on the market.To support all types of blood pump catheters simultaneously, control units with different communication interfaces would have to be developed. This would not only increase the purchase price of the devices for users, but also complicate their operation.

[0022] To solve the problems of the prior art, an embodiment of the present application provides a ventricular assist device (VAD). The ventricular assist device provided by the embodiment of the present application will first be presented below.

[0023] Fig. Figure 1 shows a schematic structural representation of the connection between the blood pump catheter 2 and the control unit for a ventricular assist device according to an embodiment of the present application. As in Fig. As shown in Figure 1, the control unit 1 for a ventricular assist device can comprise a first interface 11 and a second interface 12, wherein the first interface 11 is configured to transmit electrical signals and the second interface 12 is configured to transmit communication data.

[0024] The first interface 11 and / or the second interface 12 is designed for connection to the blood pump catheter 2.

[0025] In this embodiment, the control unit 1 can communicate with the blood pump catheter 2 via the first interface 11 and the second interface 12. For example, the first interface 11 can be configured to transmit an electrical control signal to control the operation of the blood pump catheter 2. Using this electrical control signal, various types and functions of blood pump catheters 2 can be controlled for movement within the human body.Using the example of a blood pump catheter 2 with sensors, the control signal enables the sensors to acquire physiological information of the target subject, such as blood pressure, heart rate, and temperature; The second interface 12 can be configured to transmit the target subject data acquired by the blood pump catheter 2 and / or to transmit the electrical control signal to control the operation of the blood pump catheter 2, where the data may include physiological parameters or high-resolution medical images; For some types of blood pump catheters 2, this type of blood pump catheter 2 can transmit both the target subject data and the electrical drive signal via a single interface.During data transmission, the second interface 12 enables high-speed transmission via fiber optic cable, where the data may include high-resolution medical images acquired by the blood pump catheter 2 or a variety of physiological parameters.

[0026] It should be noted that in some embodiments, the blood pump catheter 2 can be a blood pump catheter in a broader sense or any catheter with a blood pumping function. For example, it can be a catheter that simply pumps blood, or a catheter that both pumps blood and filters thrombi.

[0027] In this embodiment, the integration of a first interface 11 and a second interface 12 on the control unit 1 enables rapid data transmission during operation of the ventricular assist device (VAD). This applies regardless of the type of data acquired by the blood pump catheter 2, such as physiological parameters or high-resolution medical images, or the electrical signal transmitted from the control unit 1 to the blood pump catheter via the first interface 11. Thanks to the optical transmission via the second interface 12, the complex requirements of the control logic of the blood pump catheter 2 can be met. Furthermore, the second interface 12 allows the control unit 1 to better adapt to different functional types of blood pump catheters 2, thus accommodating various application scenarios and transmission requirements.This improves the compatibility and scalability of the control unit 1 and thus increases the adaptability of the control unit 1. For example, the first interface 11 can be an electrical interface, while the second interface 12 can be an optical interface or an optoelectronic composite interface.

[0028] In some embodiments, the second interface 12, if it is an optoelectronic composite interface, can be used independently. That is, the blood pump catheter 2 is electrically connected to the control unit 1 exclusively via the second interface 12, thus enabling the transmission of both electrical signals and any data acquired by the blood pump catheter 2, such as physiological parameters or high-resolution medical images.

[0029] In some further embodiments, the communication types of the blood pump catheter 2 can include a first communication type, a second communication type and a third communication type, wherein the first communication type is communication exclusively via the electrical interface, the second communication type can be communication via both the electrical interface and an optical communication interface, and the third communication type can be communication via the optoelectronic composite interface.

[0030] Regarding the second and third communication types mentioned above, the second interface can employ 12 different interface designs. If the second interface 12 is an optical interface, it serves to transmit the data of the target object acquired by the blood pump catheter 2. This means that this optical interface must be used simultaneously with the electrical interface, with the electrical interface transmitting the electrical control signal to control the operation of the blood pump catheter 2, while the optical interface is designed to transmit the data of the target subject acquired by the blood pump catheter 2. Thus, the requirements of the control logic and high-speed data transmission of the blood pump catheter 2 are met.

[0031] If the second interface 12 is an optoelectronic interface, it is designed to transmit the target object data acquired by the blood pump catheter 2, as well as the electrical control signal for controlling the operation of the blood pump catheter 2. This means that this second interface 12 can be designed for transmission via the dual-function connector of the blood pump catheter 2, thereby enabling both the transmission of the electrical control signal for controlling the movement of the blood pump catheter 2 within the human body and the transmission of data such as physiological parameters and large volumes of high-resolution medical data.

[0032] In this embodiment, the addition of different second interfaces 12 corresponding to the different blood pump catheters 2 not only meets the usage requirements of different types and functions of blood pump catheters 2, but also reduces the number of physical interfaces, adapts better to different application scenarios and transmission requirements, and improves the compatibility and scalability of the control unit 1.

[0033] With reference to Fig. 2 In some further embodiments, where the second interface 12 is an optoelectronic composite interface, the control unit 1 may also include the following: An optoelectronic detection chip 14, wherein the input terminal of the optoelectronic detection chip 14 is electrically connected to the optoelectronic compound interface and the output terminal of the optoelectronic detection chip 14 is electrically connected to the controller 13; An optoelectronic detection chip 14 designed to detect the connection type of the blood pump catheter 2; A controller 13 designed to control the operation of the blood pump catheter based on the connection type detected by the optoelectronic detection chip 14.

[0034] In this embodiment, where the second interface 12 is an optoelectronic interface, the optoelectronic interface functions both as an electrical interface capable of transmitting electrical control signals and as an optical communication interface capable of transmitting data from the target object. This means the optoelectronic interface can support the three communication types of the blood pump catheter 2 mentioned above. Therefore, to accurately identify the specific function performed by the optoelectronic interface, the optoelectronic detection chip 14 can detect the communication type of the blood pump catheter 2 connected to the optoelectronic interface, i.e., determine whether the blood pump catheter 2 requires optical or electrical communication.

[0035] In some embodiments, it is possible to use an optional model of the RTL8305SC for the optoelectronic detection chip 14. It should be noted that the circuit structure of the external circuitry of the detection chip can be found in the user manual for this chip and is not explained in detail here.

[0036] With reference to Fig. 3 shows Fig. 3. The specific structure of the optoelectronic interface. A first plug-in bore 122 is provided in the control unit 1. The first plug-in bore 122 is designed to accommodate the optoelectronic interface, which may include the following: A plug-in element 121, wherein the plug-in element 121 is adapted to the plug-in head of the blood pump catheter 2; A first plug-in bore 122, which is inserted into the plug-in element 121, wherein a transmission guide needle 123 is arranged in the first plug-in bore 122, the transmission guide needle 123 being electrically connected to the control unit 1; A positioning arrangement 124, which is arranged at a position of the plug element 121 corresponding to the first plug hole 122, wherein the positioning arrangement 124 is designed to position the blood pump catheter 2 when the blood pump catheter 2 is plugged into the plug element 121.

[0037] In this embodiment, the plug-in element 121 can be plugged into the control unit 1 or permanently connected to the control unit 1 at the position of the first plug-in bore 122. This means that different connection types can be used for blood pump catheters 2 with different plug-in types. When establishing optical communication between the blood pump catheter 2 and the control unit 1, the blood pump catheter 2 can be inserted into the first plug-in bore 122 by means of the positioning arrangement 124, so that the blood pump catheter 2 comes into contact with the transmission guide needle 123, enabling the control unit 1 to transmit electrical drive signals to the blood pump catheter 2 via the transmission guide needle 123. Furthermore, it can receive data transmitted from the blood pump catheter 2 via the transmission guide needle 123, such as...Physiological parameters and medical images were received.

[0038] In some embodiments, the blood pump catheter 2 is provided with a positioning block, and the positioning arrangement 124 may include the following: A second plug hole 1241, which is provided concentrically to the first plug hole 122, wherein a positioning groove 1242 is provided along the circumference of the second plug hole 1241; A positioning block attached to the blood pump catheter 2, wherein the diameter of the positioning block is adapted to the positioning groove 1242 so that the positioning block can be inserted into the positioning groove 1242.

[0039] In this embodiment, the number of positioning grooves 1242 can be three, which facilitates the positioning of the blood pump catheter 2 with the optoelectronic composite interface to ensure that the blood pump catheter 2 can be inserted accurately and quickly into the optoelectronic composite interface.

[0040] In this embodiment, when inserting the blood pump catheter 2 into the first insertion hole 122, the operator can align the positioning block of the blood pump catheter 2 with the positioning groove 1242 and then insert the positioning block into the positioning groove 1242. Simultaneously with the insertion of the positioning block into the positioning groove 1242, the connector 23 of the blood pump catheter 2 is inserted into the first insertion hole 122. This allows the blood pump catheter 2 to transmit the acquired data—for example, physiological parameters or medical images—via the transmission guide needle 123. The shielding effect of the connector element 121 also reduces external interference between the blood pump catheter 2 and the control unit 1, isolates electromagnetic interference from the optical transmission, and ensures stable communication between the blood pump catheter 2 and the control unit 1.

[0041] In some further embodiments, the control unit 1 can also include the following to ensure the quality of the signal transmitted via the optoelectronic interface: A filter 15, wherein the input terminal of the filter 15 is connected to the output terminal of the optoelectronic detection chip 14; A signal detector 16, wherein the input terminal of the signal detector 16 is electrically connected to the output terminal of the filter 15 and the output terminal of the signal detector 16 is electrically connected to the control 13.

[0042] As an example, the signal detector 16 is designed to check the quality of the data received via the second interface 12.

[0043] In this embodiment, the filter 15 is able to filter the physiological parameters and high-resolution medical images acquired by the blood pump catheter 2 to ensure the accuracy of the physiological parameters and high-resolution medical images received by the control unit 1. Simultaneously, the signal detection module can monitor the communication signal between the blood pump catheter 2 and the control unit 1 to ensure the quality of the data transmitted by the blood pump catheter 2, which may include physiological parameters or medical images.

[0044] It should be noted that signal detector 16 is a detector from the relevant technology, which can be used to check the connection stability of the optoelectronic interface as well as the quality of the transmitted data. This will not be explained in more detail here.

[0045] For example, the filter 15 can process optical and electrical signals simultaneously, or provide a filter function during the conversion between optical and electrical signals to filter out interference signals and ensure stable signal transmission.

[0046] In some further embodiments, a shielding layer can also be provided around the second interface 12 to reduce interference from electromagnetic waves.

[0047] In some further embodiments, the control unit 1 can also include the following to ensure the stability of the optical signal transmission used in the blood pump catheter 2: An optocoupler 17, wherein the input terminal of the optocoupler 17 is electrically connected to the optoelectronic interface and the output terminal of the optocoupler 17 is electrically connected to the filter 15.

[0048] In this embodiment, the optocoupler 17 is designed for electrical isolation of the optoelectronic interface.

[0049] In this embodiment, the optocoupler 17 can electrically isolate the optical and electrical signals in the blood pump catheter 2, while simultaneously interrupting the signal propagation paths and increasing interference immunity.

[0050] Furthermore, the optocoupler 17 is characterized by a low input impedance and no electrical connection between the output and input circuits, thus effectively suppressing interference signals and ensuring stable transmission of optical and electrical signals. With reference to Fig. 2 In some further embodiments, the control unit 1 may also include the following to facilitate user understanding of the communication type of this blood pump catheter 2 and to monitor the connection performance of the blood pump catheter 2: A display, wherein the display is electrically connected to the control unit 13; The display is designed to indicate the connection type of the blood pump catheter 2 connected to the second interface 12; A timer 18, wherein the timer 18 is electrically connected to the control unit 13; An alarm 19, wherein the alarm 19 is electrically connected to the control unit 13; If the connection duration recorded by the timer 18 exceeds the preset time threshold of the controller 13, the alarm 19 emits an alarm signal.

[0051] In this embodiment, when the blood pump catheter 2 is communicatively connected to the control unit 1 via the second interface 12, the display of the control unit 1 can show the connection type of the blood pump catheter 2 connected to the second interface 12. For example, the connection type could be an optical interface connection or an optoelectronic composite interface connection.

[0052] Furthermore, the timer 18 begins timing as soon as the blood pump catheter 2 is inserted into the second interface 12. If the connection duration recorded by the timer 18 exceeds the preset time threshold of the controller 13, this indicates a connection timeout between the blood pump catheter 2 and the controller 1. The controller 13 then sends an alarm signal to the alarm 19. The alarm 19 then emits an alarm signal.

[0053] A specific example of an alarm 19 is an acoustic-optical alarm 19. When an alarm signal is issued by alarm 19, the acoustic-optical alarm 19 is activated.

[0054] In some further embodiments, an embodiment of the present application also provides a ventricular assist device. With reference to Fig. 1. The ventricular assist device can include the following: The aforementioned control unit 1; A blood pump catheter 2, wherein the blood pump catheter 2 is connected to the control unit via a first interface 11 and / or a second interface 12.

[0055] In this embodiment, the control unit 1 can communicate with the blood pump catheter 2 via the first interface 11 and the second interface 12. For example, the first interface 11 can be configured to transmit an electrical control signal to control the operation of the blood pump catheter 2. Using this electrical control signal, various types and functions of blood pump catheters 2 can be controlled for movement within the human body.Using the example of a blood pump catheter 2 with sensors, the control signal enables the sensors to acquire physiological information of the target subject, such as blood pressure, heart rate, and temperature; The second interface 12 can be configured to transmit the target subject data acquired by the blood pump catheter 2 and / or to transmit the electrical control signal to control the operation of the blood pump catheter 2, where the data may include physiological parameters or high-resolution medical images; For some types of blood pump catheters 2, this type of blood pump catheter 2 can transmit both the target subject data and the electrical drive signal via a single interface.During data transmission, the second interface 12 enables high-speed transmission via fiber optic cable, where the data may include high-resolution medical images acquired by the blood pump catheter 2 or a variety of physiological parameters.

[0056] With reference to Fig. 4 In some further embodiments, an adaptable connector 23 is also provided to ensure stable communication between the blood pump catheter 2 and the control unit 1 and to allow a single control unit 1 to be adapted to several types of blood pump catheters 2. In particular, the blood pump catheter 2 may comprise the following: An electrical conductor 21, an optical transmission line 22, a plug 23 and at least one insulating element 24, wherein the insulating element 24 encloses the electrical conductor 21 and the optical transmission line 22; The electrical line 21 and the optical transmission line 22 are connected to the connector 23, the diameter of which is adapted to the diameter of the first interface 11 and / or the second interface 12.

[0057] In this embodiment, to ensure stable communication between the blood pump catheter 2 and the control unit 1, the electrical line 21 and the optical transmission line 22 of the blood pump catheter 2 can be connected to the connector 23 for the aforementioned third communication type. Depending on the type of line to be connected, the connector 23 is plugged into either the first interface 11 or the second interface 12. Simultaneously, the insulating element 24 can enclose the electrical line 21 and the optical transmission line 22 to ensure the safe operation of the ventricular assist device and to reduce interference that could impair data transmission.

[0058] In a specific example where the blood pump catheter 2 includes an insulating element 24, the insulating element 24 can comprise a first section 241 and a second section 242. A section of the electrical conductor 21 and a section of the optical transmission line are jointly enclosed in the first section 241, while another section of the electrical conductor 21 and another section of the optical transmission line 22 are each enclosed in the two second sections 242.

[0059] In particular, the first section 241 of the insulating element 24 encloses with reference to Fig. 4 both the electrical line 21 and the optical transmission line 22. One of the second sections 242 of the insulating element 24 encloses the electrical line 21 and is inserted into the electrical interface together with the connector 23 connected to the electrical line 21. The other second section 242 of the insulating element 24 encloses the optical transmission line 22 and is inserted into the second interface 12 together with the connector 23 connected to the optical transmission line 22.

[0060] In an alternative embodiment of this exemplary embodiment, in which the electrical line 21 and the optical transmission line 22 are independent of each other, the insulating element 24 encloses the electrical line 21 and the optical transmission line 22 separately.

[0061] In particular, it shows Fig. 5 a schematic representation of an alternative communication link between a blood pump catheter 2 and a control unit 1 with reference to Fig. 5. This type of connection can be used for the first and second communication types mentioned above between the blood pump catheter 2 and the control unit 1.
