DETAILED DESCRIPTION

[0045] The features and exemplary embodiments of various aspects of the present application will be described in detail below, in order to make the purposes, technical solutions and advantages of the present application more clear and apparent, the present application will be further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, but not to limit the present application. The present application can be implemented without some of these specific details by those skilled in the art. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0046] It should be noted that, in this article, relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the elements defined by the statement "include" do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0047] In the related art, since the communication and control logic of the blood pumping catheter is simple at present, the communication between the control device and the blood pumping catheter can meet the use requirements by using only the communication mode of the electrical interface, but with the development of science and technology, for some relatively complex control logic, the electrical interface is limited by the transmission speed and affected by electromagnetic interference, resulting in that some relatively complex control logic of the blood pumping catheter cannot be implemented.

[0048] In addition, with the development of science and technology, in the future development process of the ventricular assist system, only the communication mode of the electrical interface cannot meet the control and communication requirements of the future ventricular assist system, and at present, optical communication is the mainstream communication mode, so the ventricular assist system will also have corresponding optical communication requirements in the future development process, and the current ventricular assist system only has an electrical interface. In order to adapt to future development, an optical communication interface also needs to be added to the ventricular assist system to meet the optical communication requirements. If the corresponding optical communication interface is added, it may cause multiple parallel production of the control device of the ventricular assist system, that is, one control device cannot meet the communication requirements of multiple different types and different functions of the blood pumping catheter on the market. If various types of blood pumping catheters need to be met at the same time, control devices with different communication interfaces need to be developed, which not only increases the cost of purchasing equipment for users, but also increases the difficulty of operating the equipment.

[0049] In order to solve the problems in the prior art, the embodiments of the present application provide a ventricular assist system. First, the ventricular assist system provided by the embodiments of the present application will be introduced.

[0050] Figure 1 The structure schematic diagram of the connection between the control device of the ventricular assist system provided by an embodiment of the present application and the blood pumping catheter 2 of the ventricular assist system is shown. As shown in Figure 1 The control device 1 of the ventricular assist system can include a first interface 11 and a second interface 12, the first interface 11 is used to transmit electrical signals, and the second interface 12 is used to transmit communication data;

[0051] The first interface 11 and / or the second interface 12 are configured to connect with the blood pumping catheter 2.

[0052] In the embodiment, the control device 1 can communicate with the blood pumping catheter 2 through the first interface 11 and the second interface 12. As an example, the first interface 11 can be configured to transmit a driving electrical signal for driving the blood pumping catheter 2 to work. The driving electrical signal can drive different types and different functions of the blood pumping catheter 2 to move in the human body. For example, the driving electrical signal can drive the sensor to collect physiological information of the target object, such as blood pressure, heart rate, and temperature. The second interface 12 can be configured to transmit data collected by the blood pumping catheter 2 and / or transmit the driving electrical signal for driving the blood pumping catheter 2 to work. The data can be physiological parameters or high-definition medical images. For some types of blood pumping catheters 2, the blood pumping catheter 2 can transmit both the data of the target object and the driving electrical signal through one interface. In the process of transmitting the data, the second interface 12 can realize high-speed optical fiber transmission. The data can be high-definition medical images collected by the blood pumping catheter 2 or a large number of physiological parameters.

[0053] In the embodiment, by providing the first interface 11 and the second interface 12 on the control device 1, during the operation of the ventricular assist system, no matter what data the blood pumping catheter 2 collects, such as physiological parameters or high-definition medical images, or the electrical signal transmitted by the control device 1 to the blood pumping catheter through the first interface 11, fast transmission can be realized. On the basis of optical transmission of the second interface 12, the complex control logic requirements of the blood pumping catheter 2 can be met. Moreover, for the interfaces of different types of blood pumping catheters 2, the control device 1 can better adapt to different functional types of blood pumping catheters to cope with different application scenarios and transmission requirements, thereby improving the compatibility and scalability of the control device 1, and improving the adaptability of the control device 1.

[0054] As an example, the first interface 11 can be an electrical interface, and the second interface 12 can be an optical interface or an optical-electrical composite interface.

[0055] In some embodiments, in the case where the second interface 12 is an optical-electrical composite interface, it can be used alone, that is, only the blood pumping catheter 2 is electrically connected with the control device 1 through the second interface 12, which can transmit both the electrical signal and any data collected by the blood pumping catheter 2, such as physiological parameters or high-definition medical images.

[0056] In some other embodiments, the communication types of the blood pumping catheter 2 can include a first communication type, a second communication type and a third communication type, wherein the first communication type is to communicate through the electrical interface only, the second communication type can be to communicate through the electrical interface and the optical communication interface, and the third communication type can be to communicate through the optoelectronic composite interface.

[0057] For the second communication type and the third communication type described above, the second interface 12 can adopt different design interfaces. In the case where the second interface 12 is an optical interface, the optical interface is used to transmit the data of the target object collected by the blood pumping catheter 2, that is, the optical interface needs to be used at the same time as the electrical interface, the electrical interface transmits the driving electrical signal for driving the blood pumping catheter 2 to work, and the optical transmission interface is used to transmit the data of the target object collected by the blood pumping catheter 2, so as to meet the control logic requirement of the blood pumping catheter 2 and the requirement of high-speed data transmission.

[0058] In the case where the second interface 12 is an optoelectronic composite interface, the optoelectronic composite interface is used to transmit the data of the target object collected by the blood pumping catheter 2 and transmit the driving electrical signal for driving the blood pumping catheter 2 to work, that is, the second interface 12 can be used for transmission of the joint of the two-in-one blood pumping catheter 2, which can not only transmit the driving electrical signal for driving the blood pumping catheter 2 to move in the human body, but also realize data transmission, such as physiological parameters and high-definition medical data.

[0059] In the embodiment, different second interfaces 12 are added according to different blood pumping catheters 2, which can not only meet the use requirements of blood pumping catheters 2 of different types and different functions, but also reduce the number of physical interfaces, better adapt to different application scenarios and transmission requirements, and improve the compatibility and scalability of the control device 1.

[0060] Reference Figure 2 In some other embodiments, in the case where the second interface 12 is an optoelectronic composite interface, the control device 1 can further include:

[0061] an optoelectronic detection chip 14, an input end of the optoelectronic detection chip 14 being electrically connected with the optoelectronic composite interface, and an output end of the optoelectronic detection chip 14 being electrically connected with the controller 13;

[0062] the optoelectronic detection chip 14 is used to detect the connection type of the blood pumping catheter 2;

[0063] the controller 13 is used to control the blood pumping catheter to operate according to the connection type detected by the optoelectronic detection chip 14.

[0064] In the embodiment, in the case that the second interface 12 is an optoelectrical composite interface, since the optoelectrical composite interface has both the function of transmitting the driving electrical signal of the electrical interface and the function of transmitting the data of the target object of the optical communication interface, that is, the optoelectrical composite interface can meet the three communication types of the blood pumping catheter 2, in order to accurately identify which function the optoelectrical composite interface specifically implements, the optoelectrical detection chip 14 can detect the communication type of the blood pumping catheter 2 connected to the optoelectrical composite interface, that is, whether the blood pumping catheter 2 connected to the optoelectrical composite interface specifically needs the optical communication function or the electrical communication function.

[0065] In some embodiments, the optional model of the optoelectrical detection chip 14 can be RTL8305SC.

[0066] It is worth noting that the external circuit connection structure of the detection chip can refer to the manual of the chip, and will not be described here.

[0067] Referring to Figure 3 , Figure 3 The specific structure of the optoelectrical composite interface is shown, and the first plug hole 122 is opened on the control device 1, and the first plug hole 122 is used to place the optoelectrical composite interface, and the optoelectrical composite interface can include:

[0068] The plug-in part 121 is adapted to the plug-in head of the blood pumping catheter 2;

[0069] The first plug hole 122 is opened on the plug-in part 121, and the transmission needle 123 is arranged in the first plug hole 122, and the transmission needle 123 is electrically connected with the control device 1;

[0070] The positioning assembly 124 is arranged at the position corresponding to the plug-in part 121 and the first plug hole 122, and the positioning assembly 124 is used to position the blood pumping catheter 2 when the blood pumping catheter 2 is plugged with the plug-in part 121.

[0071] In the embodiment, the plug-in part 121 can be plugged with the control device 1, and can also be fixedly connected with the control device 1 at the position of the first plug hole 122, that is, different connection modes can be adopted for the blood pumping catheter 2 with different types of plug-in heads, when the blood pumping catheter 2 establishes optical communication with the control device 1, the blood pumping catheter 2 can be plugged into the first plug hole 122 according to the positioning of the positioning assembly 124, the blood pumping catheter 2 contacts with the transmission needle 123, and the control device 1 can transmit the driving electrical signal to the blood pumping catheter 2 through the transmission needle 123, and can also receive the data transmitted by the blood pumping catheter 2 through the transmission needle 123, such as physiological parameters and medical images.

[0072] In some embodiments, specifically, the positioning block is arranged on the blood pumping catheter 2, and the positioning assembly 124 can include:

[0073] A second plug hole 1241 concentric with the first plug hole 122 is provided, and a positioning groove 1242 is provided along the circumference of the second plug hole 1241;

[0074] The pump blood catheter 2 is provided with a positioning block, and the diameter of the positioning block is matched with the positioning groove 1242, so that the positioning block can be plugged into the positioning groove 1242.

[0075] In this embodiment, the number of positioning grooves 1242 can be three, which facilitates the positioning of the pump blood catheter 2 and the optoelectronic composite interface, so as to ensure that the pump blood catheter 2 can be accurately and quickly inserted into the optoelectronic composite interface.

[0076] In this embodiment, when the pump blood catheter 2 is plugged into the first plug hole 122, the staff can align the positioning block of the pump blood catheter 2 with the positioning groove 1242, and then plug the positioning block into the positioning groove 1242. At the same time when the positioning block is plugged into the positioning groove 1242, the plug 23 of the pump blood catheter 2 is plugged into the first plug hole 122. The pump blood catheter 2 can transmit the collected data such as physiological parameters or medical images through the transmission needle 123. Through the shielding effect of the plug-in part 121, the external interference between the pump blood catheter 2 and the control device 1 can be reduced, the influence of electromagnetic interference on light transmission can be isolated, and stable communication between the pump blood catheter 2 and the control device 1 can be ensured.

[0077] In some other embodiments, in order to ensure the signal quality of the optoelectronic composite interface, the control device 1 can further include:

[0078] A filter 15, an input end of the filter 15 is connected with an output end of the optoelectronic detection chip 14;

[0079] A signal detector 16, an input end of the signal detector 16 is electrically connected with an output end of the filter 15, and an output end of the signal detector 16 is electrically connected with the controller 13.

[0080] As an example, the signal detector 16 is used to detect the quality of the data received by the second interface 12.

[0081] In this embodiment, the filter 15 can filter the physiological parameters and high-definition medical images collected by the pump blood catheter 2, so as to ensure the accuracy of the physiological parameters and high-definition medical images received by the control device 1. At the same time, through the signal detection module, the signal connected between the pump blood catheter 2 and the control device 1 can be detected, so as to ensure the quality of the data transmitted by the pump blood catheter 2. The data received by the control device 1 can be physiological parameters or medical images.

[0082] It is worth noting that the signal detector 16 is a detector capable of detecting the connection stability and the quality of the transmitted data of the optoelectronic composite interface in the related art, and will not be described here.

[0083] As an example, the filter 15 can process the optical signal and the electrical signal at the same time, or can provide the filtering function when converting between the optical signal and the electrical signal to filter out the interference signal, ensuring stable transmission of the signal.

[0084] In some other embodiments, a shielding layer can also be arranged around the second interface 12 to reduce the interference of electromagnetic waves.

[0085] In some other embodiments, in order to ensure the stability of the blood pumping conduit 2 in optical signal transmission, the control device 1 can further comprise:

[0086] The optoelectronic coupler 17 is electrically connected to the optoelectronic composite interface at the input end, and is electrically connected to the filter 15 at the output end.

[0087] In the embodiment, the optoelectronic coupler 17 is used to electrically isolate the optoelectronic composite interface.

[0088] In the embodiment, the optoelectronic coupler 17 can electrically isolate the optical signal and the electrical signal in the blood pumping conduit 2, and can cut off the propagation path of the signal, thereby improving the anti-interference ability.

[0089] In addition, the optoelectronic coupler 17 has the characteristics of small input impedance, no electrical connection between the output loop and the input loop, etc., which can effectively suppress the interference signal and ensure the stable transmission of the optical signal and the electrical signal.

[0090] Referring to Figure 2 In some other embodiments, in order to facilitate the user to understand the communication type of the blood pumping conduit 2 and monitor the connection performance of the blood pumping conduit 2, the control device 1 can further comprise:

[0091] A display, which is electrically connected to the controller 13;

[0092] The display is used to display the connection type of the blood pumping conduit 2 connected to the second interface 12.

[0093] A timer 18, which is electrically connected to the controller 13;

[0094] An alarm 19, which is electrically connected to the controller 13;

[0095] In the case that the connection time counted by the timer 18 exceeds the preset time threshold of the controller 13, the alarm 19 outputs an alarm signal.

[0096] In the embodiment, when the blood pumping catheter 2 is communicatively connected with the control device 1 through the second interface 12, the display of the control device 1 can display the connection type of the blood pumping catheter 2 connected with the second interface 12, for example, the connection type can be an optical interface connection, and can also be an optical-electric composite interface connection.

[0097] Further, when the blood pumping catheter 2 is plugged into the second interface 12, the timer 18 starts timing, and if the connection time counted by the timer 18 exceeds the preset time threshold of the controller 13, it means that the blood pumping catheter 2 is connected with the control device 1 for too long, and the controller 13 sends an alarm signal to the alarm 19, and the alarm 19 outputs the alarm signal.

[0098] For example, the alarm 19 can be an audible and light alarm 19, and when the alarm 19 outputs the alarm signal, the audible and light alarm 19 starts working.

[0099] In some other embodiments, the application also provides a ventricular assist system, which refers to Figure 1 The ventricular assist system can include:

[0100] The control device 1 described above;

[0101] The blood pumping catheter 2 is connected with the control device through the first interface 11 and / or the second interface 12.

[0102] In the embodiment, the control device 1 can communicate with the blood pumping catheter 2 through the first interface 11 and the second interface 12, for example, the first interface 11 can be used to transmit a driving electrical signal for driving the blood pumping catheter 2 to work, and the driving electrical signal can drive different types and different functions of the blood pumping catheter 2 to move in the human body, for example, the driving electrical signal can drive the sensor to collect physiological information of the target object, such as blood pressure, heart rate and temperature; the second interface 12 can be used to transmit data collected by the blood pumping catheter 2 and / or transmit a driving electrical signal for driving the blood pumping catheter 2 to work, wherein the data can be physiological parameters or high-definition medical images; for some types of blood pumping catheter 2, the blood pumping catheter 2 can transmit data and driving electrical signals through one interface, and in the process of transmitting data, the second interface 12 can realize high-speed optical fiber transmission, wherein the data can be high-definition medical images collected by the blood pumping catheter 2, or a large number of physiological parameters.

[0103] Referring to Figure 4 In some other embodiments, in order to ensure stable communication between the blood pumping catheter 2 and the control device 1, and to adapt to multiple types of blood pumping catheters 2 through one control device 1, an adaptive plug 23 is also needed, specifically, the blood pumping catheter 2 can include:

[0104] the electric wire 21 and the light transmission wire 22 are covered by the insulating member 24;

[0105] The electric wire 21 and the light transmission wire 22 are connected with the plug 23, and the diameter of the plug 23 is adapted to the diameter of the first interface 11 and / or the second interface 12.

[0106] In the embodiment, in order to ensure that the blood pumping conduit 2 can stably communicate with the control device 1, for the blood pumping conduit 2 of the third communication type, the electric wire 21 and the light transmission wire 22 can be connected with the plug 23, and the plug 23 is plugged into the first interface 11 or the second interface 12 according to the connection of different types of wires. Meanwhile, the insulating member 24 can cover the electric wire 21 and the light transmission wire 22, so as to ensure the safety of the ventricular assist system and reduce the interference of data transmission.
