[0084] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

It should be noted that in the description of the embodiments of the present application, the words "first", "second", etc. are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0086] The "parallel" and "perpendicular" involved in this application are "substantially parallel" and "substantially perpendicular" in actual operation. "Substantially parallel" can be understood as parallel with a certain error, and similarly, "substantially perpendicular" can be understood as perpendicular with a certain error.

[0087] The “plane” referred to in this application is a “plane substantially parallel to the horizontal plane” in actual operation.

[0088] For ease of understanding, the technical terms involved in this application are explained and described below.

[0089] The embodiments of the present application provide a fluid handling device, a control device and a transcatheter ventricular assist device to prevent the various pipeline branches of the flushing pipeline from being entangled with each other, facilitate the operator to install the flushing pipeline, and reduce the installation error rate of the flushing pipeline.

[0090] For ease of description, the transcatheter ventricular assist device provided in an embodiment of the present application is first described below.

[0091] The transcatheter ventricular assist device includes a control device, also known as a control host, and an interventional pump system used in conjunction with it. It is an interventional blood pump that can provide mechanical circulatory assistance to patients with relevant indications. Users can monitor the system status and patient physiological parameters on the control host interface, and provide different degrees of circulatory assistance by adjusting the speed of the interventional pump according to the patient's needs, thereby temporarily maintaining blood circulation in the patient's vital organs and unloading the heart.

[0092] The interventional pump system mainly includes the interventional pump, delivery system and flushing pipeline.

[0093] The interventional pump mainly includes a drive catheter handle, a drive catheter and a pump head. The interventional pump can be percutaneously inserted into the heart through a peripheral blood vessel, and the pump head will be inserted between the left ventricle and the ascending aorta. The blood inlet of the pump head will be inserted into the left ventricle, and the blood outlet of the pump head will be inserted into the ascending aorta, thereby pumping blood from the left ventricle into the aorta to achieve ventricular assist function.

[0094] The delivery system mainly includes a dilator, an interventional sheath, and an introducer. The delivery system is used to dilate blood vessels and provide a pathway for the interventional pump to be placed into the heart. The introducer and interventional sheath have the function of folding the pump head. The introducer and dilator will be removed after the interventional pump is placed in place. The interventional sheath will continue to exist in the patient's blood vessels until the interventional pump is removed. When the interventional pump is removed, the interventional sheath will also play the role of folding the pump head.

[0095] The flushing pipeline includes a flushing kit and an arterial pressure measurement kit, and a flushing pump is installed on the flushing kit. The fluid drive device of the control host drives the flushing pump, which can pump the flushing fluid into the interventional pump, thereby preventing blood from entering the interventional pump drive catheter. Among them, the fluid drive device can be understood as a flushing pump drive device.

[0096] The control host mainly includes: a control console, an interventional pump drive device, and the fluid drive device mentioned above.

[0097] The interventional pump drive device can be connected to the interventional pump to drive the impeller in the pump head to rotate, thereby pumping blood from the left ventricle into the ascending aorta. The speed of the drive motor can be set by rotating the knob on the console. During operation, if any high-risk situation occurs, the interventional pump drive device will send an alarm signal to the console.

[0098] The console provides users with a simple and intuitive operating interface to achieve the following functions: monitor the operating status of the transcatheter ventricular assist device; display the system operating status and patient physiological data, including speed, blood pressure and flow; control the speed of the drive motor and flushing pump; support the setting of alarm thresholds and system parameters; the console provides different levels of alarms and automatically records various alarm information, and related charts will be displayed in the summary report.

[0099] In the above transcatheter ventricular assist device, after the driving catheter handle, the flushing pipeline, and the fluid driving device are connected, a flushing channel will be formed. The driving catheter handle includes a driving catheter flushing pipeline inlet connector, a driving catheter flushing pipeline outlet connector, an arterial pressure measurement pipeline inlet connector, and an arterial pressure measurement pipeline outlet connector.

[0100] The driving catheter flushing pipeline inlet connector and the driving catheter flushing pipeline outlet connector are respectively connected to the pipeline (flushing pipeline) in the flushing kit. The arterial pressure measurement pipeline inlet connector is connected to the pipeline (arterial pressure measurement pipeline) of the arterial pressure measurement kit, and the flushing fluid is connected to the pressure measurement interface of the intervention sheath through the arterial pressure measurement pipeline outlet connector. The gap between the intervention sheath and the driving catheter, the driving catheter handle and the arterial pressure measurement pipeline are connected to form an arterial pressure measurement path.

[0101] like Figure 1 As shown, the interventional pump driving device 2B is connected to the driving catheter handle 3B, and the driving catheter handle 3B needs to be connected to the pipeline branch of the flushing pipeline.

[0102] The fluid driving device 100 is placed on the console 200 . Both the fluid driving device 100 and the console 200 can be understood as components in the control device 1B.

[0103] In some embodiments, the console 200 has a first state for application to an extracorporeal magnetically levitated artificial heart and a second state for application to an interventional artificial heart; in the first state, the magnetically levitated motor is disposed on the console 200; in the second state, the fluid drive device 100 is disposed on the console 200.

[0104] In some other embodiments, the console 200 may be selected to have only a state for application to an interventional artificial heart.

[0105] The structure and shape of the console 200 are selected according to actual conditions, and this embodiment does not limit this.

[0106] In actual situations, the fluid driving device 100 may not be arranged on the console 200 , for example, the fluid driving device 100 may be arranged separately.

[0107] The fluid driving device 100 provided in the embodiment of the present application is described in detail below.

[0108] like Figure 2 As shown, the fluid driving device 100 provided in the embodiment of the present application is used to drive the fluid in the flushing pipeline 4B to enter the interventional instrument (such as an interventional pump), and the flushing pipeline 4B includes a pipeline branch 41.

[0109] The fluid drive device 100 includes a placement area 3, which corresponds to the pipeline branch 41. The placement area 3 is provided with at least three installation positions 31 arranged in the first axial direction. Figure 2 As shown, the mounting position 31 can be a groove. In actual situations, the mounting position 31 can also be a structure or a hole with clamping parts on both sides. The mounting position 31 can be directly formed by the drive housing 2 of the fluid drive device 100; the mounting position 31 can also be relatively independent of the drive housing 2, and the mounting position 31 can be set on the drive housing 2 by bonding, clamping, welding, etc.; the mounting position 31 can also be a part of the flushing pump that clamps the pipeline.

[0110] The structures of all the mounting positions 31 arranged in the first axial direction may be the same or different. Figure 2 As shown, in the first placement area 3a, there are three mounting positions 31 arranged in the first axial direction, namely the first mounting position 311a of the first placement area, the second mounting position 312a of the first placement area and the third mounting position 313a of the first placement area; wherein the first mounting position 311a of the first placement area and the second mounting position 312a of the first placement area are both grooves, which can be set on the drive housing 2 or formed by the drive housing 2; the third mounting position 313a of the first placement area is the part that clamps the pipeline in the flushing pump 1 (infusion pump 1a). In the second placement area 3b, there are three mounting positions 31 arranged in the first axial direction, namely the first mounting position 311b of the second placement area, the second mounting position 312b of the second placement area and the third mounting position 313b of the second placement area; wherein the first mounting position 311b of the second placement area and the second mounting position 312b of the second placement area are both grooves, which can be set on the drive housing 2 or formed by the drive housing 2; the third mounting position 313b of the second placement area is the part that clamps the pipeline in the flushing pump 1 (circulating pump 1b).

[0111] The pipeline branches 41 are sequentially arranged in at least three installation positions 31 in the order of connecting the inlet and outlet of adjacent installation positions. The adjacent installation positions refer to the installation positions adjacent along the first axial direction in each placement area. For example, the first installation position 311a of the first placement area and the third installation position 313a of the first placement area are adjacent installation positions, and the second installation position 312a of the first placement area and the third installation position 313a of the first placement area are adjacent installation positions. The fluid outlet of one of the adjacent installation positions and the fluid inlet of the other are distributed on the same side of the second axial direction, and the first axial direction and the second axial direction intersect. The pipeline branch 41 is curved in the shape of an "S"-shaped wave curve in its corresponding placement area 3.

[0112] For example, Figure 2 As shown, the two sides on the second axis are respectively the right side and the left side of the second axis as an example ( Figure 2 The right side and the left side shown in the figure are only exemplary and can be interchanged), the two pipeline branches 41 are respectively the first pipeline branch 41a and the second pipeline branch 41b, there are two placement areas which are respectively the first placement area 3a and the second placement area 3b, the multiple mounting positions 31 of the first placement area 3a include the first mounting position 311a of the first placement area, the second mounting position 312a of the first placement area and the third mounting position 313a of the first placement area, the multiple mounting positions 31 of the second placement area 3b include the first mounting position 311b of the second placement area, the second mounting position 312b of the second placement area and the third mounting position 313 of the second placement area. The first pipeline branch 41a is installed in the first placement area 3a, specifically, the first pipeline branch 41a is installed in the first installation position 311a of the first placement area, the second installation position 312a of the first placement area and the third installation position 313a of the first placement area; the second pipeline branch 41b is installed in the second placement area 3b, specifically, the second pipeline branch 41b is installed in the first installation position 311b of the second placement area, the second installation position 312b of the second placement area and the third installation position 313 of the second placement area.

[0113] The first pipeline branch 41a extends from the first installation position 311a of the first placement area to the left side of the second axial direction, enters the third installation position 313a of the first placement area on the left side of the second axial direction and extends to the right side of the second axial direction, then enters the second installation position 312a of the first placement area on the right side of the second axial direction and extends to the left side of the second axial direction, so that the first pipeline branch 41a is in a curved shape similar to an "S"-shaped wave curve in its corresponding first placement area 3a. Of course, there are other installation methods for the first pipeline branch 41a, for example, the first pipeline branch 41a is first installed at the second installation position 312a of the first placement area, then installed at the third installation position 313a of the first placement area, and then installed at the first installation position 311a of the first placement area.

[0114] The second pipeline branch 41b extends from the first installation position 311b of the second placement area to the right side of the second axial direction, enters the third installation position 313b of the second placement area on the right side of the second axial direction and extends to the left side of the second axial direction, then enters the second installation position 312b of the second placement area on the left side of the second axial direction and extends to the right side of the second axial direction, so that the second pipeline branch 41b is in a curved shape similar to an "S"-shaped wave curve in its corresponding second placement area 3b. Of course, there are other installation methods for the second pipeline branch 41b, for example, the second pipeline branch 41b is first installed at the second installation position 312b of the second placement area, then installed at the third installation position 313b of the second placement area, and then installed at the first installation position 311b of the second placement area.

[0115] In the above-mentioned fluid drive device, because the pipeline branch 41 is in a curved shape similar to an "S"-shaped wave curve in its corresponding placement area 3, this prevents the pipeline branch 41 from being entangled or knotted. At the same time, after such a design, the distribution of the pipeline branch 41 itself is planned, which facilitates the operator to install the pipeline branch 41, reduces the installation error rate of the pipeline branch 41 itself, and effectively reduces the installation time and installation error rate of the flushing pipeline 4B.

[0116] In the above fluid driving device, because the pipeline branch 41 is curved like an "S"-shaped wave curve in its corresponding placement area 3, the fluids corresponding to two adjacent installation positions 31 in at least three installation positions 31 in the placement area 3 flow in opposite directions. Figure 2 As shown, in the part of the first pipeline branch 41a at the second installation position 312a of the first placement area, the fluid flows from the left side to the right side, in the part of the first pipeline branch 41a at the third installation position 313a of the first placement area, the fluid flows from the right side to the left side, and in the part of the first pipeline branch 41a at the first installation position 311a of the first placement area, the fluid flows from the left side to the right side. Therefore, for the first placement area 3a, the fluid flow direction at the second installation position 312a of the first placement area is opposite to the fluid flow direction at the third installation position 313a of the first placement area, and the fluid flow direction at the third installation position 313a of the first placement area is opposite to the fluid flow direction at the first installation position 311a of the first placement area; the same is true for the second placement area 3b, which will not be repeated here.

[0117] It should be noted that the “S”-shaped wave curve can be understood as a serpentine wave curve. Figure 2 The shape of the first pipeline branch 41a and the form of the second pipeline branch 41b are shown.

[0118] Figure 3Four types of "S" wave curves are shown. Figure 2 and Figure 3 As shown, the shape of the first pipeline branch 41a can also be Figure 3 (1) The curved shape of the "S"-shaped wave curve shown in Figure 3 (3) The curved shape of the "S"-shaped wave curve shown in FIG. 4; The shape of the second pipeline branch 41b can also be Figure 3 (2) The curved shape of the "S"-shaped wave curve shown in Figure 3 (4) The curved shape of the "S"-shaped wave curve shown.

[0119] In actual situations, the “S”-shaped wave curve is not limited to Figure 2 and Figure 3 The shape shown may also be other “S”-shaped wave curves, which is not limited in the embodiments of the present application.

[0120] There are multiple pipeline branches 41 in the flushing pipeline 4B, and there are multiple placement areas 3 in the fluid drive device 100. It should be noted that multiple means two or more.

[0121] At least some of the multiple pipeline branches 41 correspond to the multiple placement areas 3 one by one, and the multiple placement areas 3 are arranged in the second axial direction.

[0122] It should be noted that at least some of the multiple pipeline branches 41 correspond one-to-one to the multiple placement areas 3. Exemplarily, the multiple pipeline branches 41 are three pipeline branches 41, and two pipeline branches 41 among the three pipeline branches 41 correspond one-to-one to the two placement areas 3; the multiple pipeline branches 41 are three pipeline branches 41, and the three pipeline branches 41 correspond one-to-one to the three placement areas 3; the multiple pipeline branches 41 are four pipeline branches 41, and two pipeline branches 41 among the four pipeline branches 41 correspond one-to-one to the two placement areas 3.

[0123] In the above structure, at least some of the multiple pipeline branches 41 can be located in different placement areas 3. Moreover, since the multiple placement areas 3 are arranged in the second axial direction, the multiple pipeline branches 41 corresponding to the placement areas 3 can be arranged along the second axial direction, thereby realizing isolation between different pipeline branches 41 and avoiding mutual entanglement and knotting of different pipeline branches 41. At the same time, each pipeline branch 41 corresponding to the placement area 3 has a specific placement area 3, which facilitates the operator to install each pipeline branch 41 corresponding to the placement area 3, reduces the probability of installation misalignment between multiple pipeline branches 41, and effectively reduces the installation time and installation error rate of the flushing pipeline 4B.

[0124] Through the above analysis, it can be known that the fluid driving device provided in the embodiment of the present application can realize that each pipeline branch 41 corresponding to the placement area 3 is in a curved shape of an "S"-shaped wave curve in its corresponding placement area 3, which effectively avoids the entanglement and knotting of multiple pipeline branches 41 with each other, and also avoids the entanglement and knotting of the pipeline branches 41 themselves. At the same time, the distribution of the pipeline branches 41 themselves and the distribution of each pipeline branch 41 corresponding to the placement area 3 are planned, which facilitates the operator to install the flushing pipeline 4B, and effectively reduces the installation time and installation error rate of the flushing pipeline 4B.

[0125] In some embodiments, in order to facilitate the placement of the pipeline branch 41 in the installation position 31, the pipeline direction corresponding to at least one installation position 31 in the placement area 3 may be selected to be along the second axial direction. Based on this, the pipeline direction corresponding to at least three installation positions 31 in the placement area 3 may also be selected to be along the second axial direction.

[0126] For example, Figure 2 As shown, the pipeline corresponding to the first installation position 311a of the first placement area runs along the second axial direction, the pipeline corresponding to the second installation position 312a of the first placement area runs along the second axial direction, the pipeline corresponding to the first installation position 311b of the second placement area runs along the second axial direction, and the pipeline corresponding to the second installation position 312b of the second placement area runs along the second axial direction.

[0127] It should be noted that the pipeline corresponding to the installation position 31 refers to the part of the pipeline in the pipeline branch 41 located in the installation position 31.

[0128] In the above embodiment, the pipeline corresponding to at least one installation position 31 runs along the second axial direction, so that the pipeline will not bend in the installation position 31, shortening the length of the bending part of the pipeline branch 41 and reducing the fluid flow resistance in the pipeline branch 41; at the same time, the pipeline can extend out of the installation position 31 along the second axial direction, and the pipeline extended along the second axial direction can be easily bent to one side on the first axial direction and enter another installation position 31, which can increase the bending angle of the pipeline branch 41 between two adjacent installation positions 31, thereby facilitating the operator to install the pipeline branch 41.

[0129] In actual situations, the direction of the pipeline corresponding to the installation position 31 may be selected to be relatively inclined with respect to the second axis, or the direction of the pipeline corresponding to the installation position 31 may be in other directions, which is not limited in the embodiments of the present application.

[0130] As described above, the plurality of placement areas 3 include a first placement area 3a and a second placement area 3b, and the plurality of pipeline branches 41 include a first pipeline branch 41a and a second pipeline branch 41b; wherein the first pipeline branch 41a is placed in the first placement area 3a, and the second pipeline branch 41b is placed in the second placement area 3b. In order to ensure that the first pipeline branch 41a is curved like an "S"-shaped wave curve in its corresponding first placement area 3a, and the second pipeline branch 41b is curved like an "S"-shaped wave curve in its corresponding second placement area 3b, the curved shape of the first pipeline branch 41a and the curved shape of the second pipeline branch 41b can be selected to be axially symmetrical.

[0131] like Figure 2 As shown, part of the pipeline between the first installation position 311a in the first placement area and the third installation position 313a in the first placement area in the first pipeline branch 41a is on the left side of the first placement area 3a, and part of the pipeline between the first installation position 311b in the second placement area and the third installation position 313b in the second placement area in the second pipeline branch 41b is on the right side of the second placement area 3b; part of the pipeline between the third installation position 313a in the first placement area and the second installation position 312a in the first placement area in the first pipeline branch 41a is on the right side of the first placement area 3a, and part of the pipeline between the third installation position 313b in the second placement area and the second installation position 312b in the second placement area in the second pipeline branch 41b is on the left side of the second placement area 3b; the part of the first pipeline branch 41a away from the first placement area 3a is located on the left side of the first placement area 3a, and the part of the second pipeline branch 41b away from the second placement area 3b is located on the right side of the second placement area 3b.

[0132] Taking the installation of the first pipeline branch 41a, the connecting vessel connecting the first pipeline branch 41a and the second pipeline branch 41b in sequence as an example, the first pipeline branch 41a passes through the second installation position 312a of the first placement area from left to right, bends to the left side of the first placement area 3a, enters the third installation position 313a of the first placement area and extends out from the left side of the first placement area 3a, bends to the right side of the first placement area 3a and enters the first installation position 311a of the first placement area; install the connector; then install the second pipeline branch 41b. Since the bending shape of the first pipeline branch 41a and the bending shape of the second pipeline branch 41b are axially symmetrical, the second pipeline branch 41b is installed in the first installation position 311b of the second placement area from left to right in the second placement area 3b, and extends out from the right side of the second placement area 3b. In this way, the first placement area can be realized. The pipeline of the first installation position 311a and the pipeline of the first installation position 311b of the second placement area are arranged in parallel or on the same axis, which reduces the bending of the flushing pipeline 4B, thereby reducing the fluid flow resistance in the flushing pipeline 4B; the second pipeline branch 41b extends from the right side of the second placement area 3b to the first installation position 311b of the second placement area, bends to the left side of the second placement area 3b, and enters the third installation position 313b of the second placement area. In this way, the second pipeline branch 41b is installed on the right side of the second placement area 3b, which increases the space for installing the second pipeline branch 41b, thereby facilitating the operator to install the second pipeline branch 41b; the second pipeline branch 41b extends from the left side of the second placement area 3b to the third installation position 313b of the second placement area, bends to the right side of the second placement area 3b, enters the first installation position 311b of the second placement area, and extends from the right side of the second placement area 3b.

[0133] Taking the example of installing the communicating vessel first and then installing the first pipeline branch 41a and the second pipeline branch 41b, after the communicating vessel is installed, the first pipeline branch 41a extends to the left in the second axial direction, and the second pipeline branch 41b extends to the right in the second axial direction. The first pipeline branch 41a extends from the left side of the first placement area 3a to the first installation position 311a of the first placement area, and the first pipeline branch 41a bends to the right side of the first placement area 3a and enters the third installation position 313a of the first placement area, and then extends from the right side of the first placement area 3a to the third installation position 313a of the first placement area, and the first pipeline branch 41a extends to the first placement area 3a. After bending to the left side of the second placement area 3a, the second pipeline branch 41b enters the second installation position 312a of the first placement area and extends from the left side of the first placement area 3a; the second pipeline branch 41b extends from the right side of the second placement area 3b to the first installation position 311b of the second placement area, the second pipeline branch 41b bends to the left side of the second placement area 3b and enters the third installation position 313b of the second placement area, and then extends from the left side of the second placement area 3b to the third installation position 313b of the second placement area, the second pipeline branch 41b bends to the right side of the second placement area 3b and enters the second installation position 312b of the second placement area and extends from the right side of the second placement area 3b. In this way, the mutual interference between the installation of the first pipeline branch 41a and the second pipeline branch 41b is avoided, which makes it convenient for the operator to install the first pipeline branch 41a at the first installation position 311a of the first placement area, and the second pipeline branch 41b at the first installation position 311b of the second placement area; at the same time, the pipeline of the first installation position 311a of the first placement area and the pipeline of the first installation position 311b of the second placement area can be arranged in parallel or coaxially, thereby reducing the bending of the flushing pipeline 4B, thereby reducing the fluid flow resistance in the flushing pipeline 4B.

[0134] In combination with the above content, it can be seen that the bending shape of the first pipeline branch 41a and the bending shape of the second pipeline branch 41b are axially symmetrical, which reduces the bending of the flushing pipeline 4B, thereby reducing the fluid flow resistance in the flushing pipeline 4B; it also facilitates the operator to install the first pipeline branch 41a in the first installation position 311a of the first placement area, and the second pipeline branch 41b in the first installation position 311b of the second placement area, thereby facilitating the operator to install the flushing pipeline 4B.

[0135] Optionally, the first placement area 3a and the second placement area 3b are respectively the placement areas 3 at the two ends of the second axis. In addition to the above-mentioned technical effects, such a setting can also reduce the impact of other pipeline branches 41 on the installation of the first pipeline branch 41a, and reduce the impact of other pipeline branches 41 on the installation of the second pipeline branch 41b, further facilitating the operator to install the flushing pipeline 4B.

[0136] Of course, the bending shape of the first pipeline branch 41a may be selected to be consistent with the bending shape of the second pipeline branch 41b, and is not limited to the above embodiment.

[0137] It should be noted that the bending shape is axisymmetric, which means that the bending direction is axisymmetric. For example, Figure 3 (1) The curve and Figure 3 (2) The curve shown in the figure is axisymmetric. Figure 3 (3) The curve and Figure 3 The bending shape of the curve shown in (4) is axisymmetric. Figure 3 (1) The curve and Figure 3 (3) The curvature of the curve shown in Figure 1 is consistent. Figure 3 (2) The curve and Figure 3 (4) The curvature of the curve shown remains consistent.

[0138] As described above, the at least three installation positions 31 corresponding to the first pipeline branch 41a include a first installation position, a second installation position and a third installation position. It can be understood that the first installation position 311a of the first placement area is a first installation position, and the first installation position 311b of the second placement area is another first installation position; the second installation position 312a of the first placement area is a second installation position, and the second installation position 312b of the second placement area is another second installation position; the third installation position 313a of the first placement area is a third installation position, and the third installation position 313b of the second placement area is another third installation position.

[0139] In order to facilitate the placement of the pipeline branch 41 and effectively avoid the pipeline branch 41 from being entangled itself, a first installation position can be selected to install the end of the pipeline branch 41 close to the branch intersection, a second installation position can be selected to install the end of the pipeline branch 41 away from the branch intersection, and a third installation position can be selected to be between the first installation position and the second installation position in the first axial direction; wherein the branch intersection refers to the intersection and connection of multiple pipeline branches 41.

[0140] Exemplarily, the first mounting position 311a of the first placement area is used to install one end of the first pipeline branch 41a close to the branch intersection, the second mounting position 312a of the first placement area is used to install one end of the first pipeline branch 41a away from the branch intersection, and the third mounting position 313a of the first placement area is between the first mounting position 311a of the first placement area and the second mounting position 312a of the first placement area in the first axial direction; the first mounting position 311b of the second placement area is used to install one end of the second pipeline branch 41b close to the branch intersection, the second mounting position 312b of the second placement area is used to install one end of the second pipeline branch 41b away from the branch intersection, and the third mounting position 313b of the second placement area is between the first mounting position 311b of the second placement area and the second mounting position 312b of the second placement area in the first axial direction; wherein, the branch intersection refers to the intersection and connection of multiple first pipeline branches 41a and second pipeline branches 41b.

[0141] In the above structure, the correspondence between different positions of the pipeline branch 41 and different installation positions improves the installation stability of the pipeline branch 41, facilitates the placement of the pipeline branch 41, and effectively avoids the pipeline branch 41 from being entangled or tangled.

[0142] In actual situations, the first installation position 31 , the second installation position and the third installation position may also be selected to install other parts of the pipeline branch 41 , and this embodiment of the present application does not limit this.

[0143] In some embodiments, the fluid-driven device 100 includes multiple flushing pumps 1, and the multiple flushing pumps 1 include an infusion pump 1a and a circulation pump 1b. The infusion pump 1a is arranged in the first placement area 3a, and the circulation pump 1b is arranged in the second placement area 3b; the first pipeline branch 41a includes an infusion tube, and the second pipeline branch 41b includes a circulation inlet tube; the infusion tube is connected to the liquid storage device, and the infusion pump 1a is provided with a third installation position 313a in the first placement area corresponding to the infusion tube, and the infusion pump 1a is used to pump the fluid in the liquid storage device into the interventional instrument through the flushing pipeline 4B; the circulation inlet tube is connected to the flushing liquid inlet of the interventional instrument, and the circulation pump 1b is provided with a third installation position 313b in the second placement area corresponding to the circulation inlet tube, and the circulation pump 1b is used to drive the fluid to circulate between the interventional instrument and the flushing pipeline 4B. In this way, a fluid driving mode of the infusion pump 1a and the circulation pump 1b is provided, and the pump speed of the fluid pumped into the interventional device can be adjusted by adjusting the pump speed of the infusion pump 1a and the circulation pump 1b; the correspondence between the infusion tube and the infusion pump 1a, and the correspondence between the circulation inlet tube and the circulation pump 1b are also achieved, ensuring the connection between the infusion tube and the infusion pump 1a, and the connection between the circulation inlet tube and the circulation pump 1b, reducing the probability of the infusion tube and the circulation pump 1b being connected, and the probability of the circulation inlet tube and the infusion pump 1a being connected, and facilitating the operator to install the flushing pipeline 4B. In addition, by providing the third installation position for the infusion pump 1a and the circulation pump 1b themselves, it is avoided to reserve another position to set the third installation position, effectively reducing the volume of the entire fluid driving device, and simplifying the structure of the entire fluid driving device.

[0144] In the embodiment of the present application, in the fluid driving mode of the infusion pump 1a and the circulation pump 1b dual pumps connected in series, the multiple pipeline branches 41 also include a third pipeline branch, and the third pipeline branch is placed in the placement area corresponding to it. The placement area corresponding to the third pipeline branch 41c can be on the pipeline fixing component 22 or other positions.

[0145] The third pipeline branch 41c may include a circulation outlet pipe 41c, the infusion pipe, the circulation inlet pipe and the circulation outlet pipe 41c are connected to each other, and the fluid driving device 100 further includes a fourth installation position 4 corresponding to the circulation outlet pipe 41c. In this way, the entanglement between the circulation outlet pipe 41c and the infusion pipe and the entanglement between the circulation outlet pipe 41c and the circulation inlet pipe are avoided, and the probability of entanglement between the pipeline branches 41 in the flushing pipeline 4B is further reduced.

[0146] In order to simplify the structure of the fluid driving device and facilitate the placement of the infusion tube, the circulation inlet tube and the circulation outlet tube 41c, the fourth mounting position 4, the first mounting position 311a of the first placement area corresponding to the infusion tube and the first mounting position 311b of the second placement area corresponding to the circulation inlet tube can be selected to be arranged in the same mounting part, such as the pipeline fixing assembly 22.

[0147] like Figure 4-Figure 7As shown, in some embodiments, the fluid drive device 100 includes a drive housing 2, and the drive housing 2 includes a drive housing body 21 and a pipeline fixing assembly 22; wherein the pipeline fixing assembly 22 is detachably mounted on the drive housing body 21, and the pipeline fixing assembly 22 is used to place the branch intersection portion of the flushing pipeline 4B, and the branch intersection portion is a portion where multiple pipeline branches 41 are intersected and connected. Exemplarily, the multiple pipeline branches 41 of the flushing pipeline 4B include a first pipeline branch 41a, a second pipeline branch 41b, and a circulation outlet pipe 41c, and the branch intersection portion includes: the intersection of the first pipeline branch 41a, the second pipeline branch 41b, and the circulation outlet pipe 41c, the portion of the first pipeline branch 41a close to the branch intersection, the portion of the second pipeline branch 41b close to the branch intersection, and the portion of the circulation outlet pipe 41c close to the branch intersection.

[0148] As mentioned above, the fluid drive device has a placement area 3, and the first mounting position of each or at least one placement area 3 is set on the pipeline fixing component 22. Exemplarily, the first mounting position 311a of the first placement area and the first mounting position 311b of the second placement area are set on the pipeline fixing component 22.

[0149] As mentioned above, the fluid driving device 100 further includes a fourth installation position 4 corresponding to the circulation outlet pipe 41 c . In this case, the fourth installation position 4 is disposed on the pipeline fixing assembly 22 .

[0150] In the above embodiment, by placing the branch intersection part of the flushing pipeline 4B in the pipeline fixing assembly 22, the pipeline fixing assembly 22 is detachably mounted on the driving housing body 21. In this way, when the design of the flushing pipeline is changed, for example, the communication vessels connecting the various pipeline branches are changed, only the mechanical design of the pipeline fixing assembly 22 can be changed without changing the entire driving housing 2; when different flushing pipelines are used, for example, different communication vessels of the flushing pipelines are used, the corresponding pipeline fixing assembly 22 can be replaced without replacing the entire driving housing 2. Therefore, the above structure improves the adaptability of the fluid drive device 100 and reduces the cost.

[0151] In order to facilitate the installation of the pipeline fixing component 22, the drive housing body 21 can be optionally provided with a groove 2103, and the pipeline fixing component 22 can be detachably arranged in the groove 2103. In this way, the groove bottom wall of the groove 2103 supports the pipeline fixing component 22, thereby facilitating the installation of the pipeline fixing component 22.

[0152] like Figure 2 , Figure 4 , Figure 8-Figure 10As shown, in the embodiment of the present application, the fluid drive device 100 includes a flushing pump 1 and a drive housing 2, and the drive housing 2 includes a fixedly connected drive upper housing 2101 and a drive bottom housing 2102; wherein, at least three mounting positions are arranged on the drive upper housing 2101; the motor 11 of the flushing pump 1 is fixed to the inner side of the drive upper housing 2101; the control module 6 of the fluid drive device 100 is arranged on the inner side of the drive bottom housing 2102, and the control module 6 is connected to the motor 11 and is used to control the motor 11. In this way, according to the structure of the drive housing 2, the motor 11 of the flushing pump 1 and the control module 6 are reasonably arranged, which improves the structural compactness of the entire fluid drive device 100 and facilitates the connection of the control module 6 and the motor 11.

[0153] It should be noted that, when the drive housing 2 includes the drive housing body 21 and the pipe fixing assembly 22, the first mounting position of at least three mounting positions 31 is arranged on the drive upper housing 2101 through the pipe fixing assembly 22. The drive upper housing 2101 and the drive bottom housing 2102 can both be understood as a part of the drive housing body 21.

[0154] Combination Figure 7 and Figure 8 As shown, the driving upper shell 2101 includes a first platform portion 21011, a second platform portion 21013 and an inclined portion 21012, the first platform portion 21011 is higher than the second platform portion 21013, the inclined portion 21012 connects the first platform portion 21011 and the second platform portion 21013, and the first platform portion 21011, the inclined portion 21012 and the second platform portion 21013 are sequentially connected in the first axial direction; wherein, the motor 11 is installed on the inclined portion 21012, which can be understood as the flushing pump 1 is installed on the inclined portion 21012. In this way, compared with the fully flat structure, the structure of the driving upper shell 2101 can save volume, so that the driving casing 2 is easy to adapt to the console 200; compared with the fully inclined structure, the first platform part 21011 and the second platform part 21013 of the driving upper shell 2101 are easier to install the flushing pipeline 4B, making the installation of the flushing pipeline 4B more stable; the flushing pump 1 is installed on the inclined part 21012, which makes it easier for the operator to operate the flushing pump 1 and also convenient to install the flushing pipeline 4B on the flushing pump 1; a control module also needs to be installed at the bottom of the flushing pump 1, and the motor 11 is suspended and fixed on the inclined part 21012, reserving space for installing the control module, thereby improving the structural compactness of the entire device and facilitating the heat dissipation of the motor 11.

[0155] In the above structure, the rotation speed of the infusion pump 1a is relatively low, and the rotation speed of the circulation pump 1b is relatively high. The circulation pump 1b is installed on the inclined portion 21012, so that the flushing liquid is not only subjected to the force of the circulation pump 1b, but also to the gravity, which can increase the flow rate of the circulation pump 1b, facilitate the circulation of the flushing liquid, and also facilitate meeting the high rotation speed requirement of the circulation pump 1b.

[0156] It should be noted that the inclined portion 21012 is provided with a flushing pump mounting hole 2104 for mounting the flushing pump 1, and the flushing pump mounting hole 2104 corresponds to the flushing pump 1. In the case where one flushing pump 1 is an infusion pump 1a and one flushing pump 1 is a circulation pump 1b, one flushing pump mounting hole 2104 is an infusion pump mounting hole 2104a, and one flushing pump mounting hole 2104 is a circulation pump mounting hole 2104b.

[0157] As described above, the plurality of placement areas 3 include a first placement area 3a and a second placement area 3b. The first placement area 3a includes a portion of the first platform portion 21011, a portion of the second platform portion 21013, and a portion of the inclined portion 21012, and the pipeline fixing assembly 22 is disposed on the first platform portion 21011. Specifically, the first installation position 311a of the first placement area is located on the first platform portion 21011, the second installation position 312a of the first placement area is located on the second platform portion 21013, and the third installation position 313a of the first placement area is located on the inclined portion 21012. The second placement area 3b includes a portion of the first platform portion 21011, a portion of the second platform portion 21013, and a portion of the inclined portion 21012. Specifically, the first installation position 311b of the second placement area is located on the first platform portion 21011, the second installation position 312b of the second placement area is located on the second platform portion 21013, and the third installation position 313b of the second placement area is located on the inclined portion 21012. In this case, the pipeline corresponding to the first installation position 311a of the first placement area runs along the second axial direction, and the pipeline corresponding to the second installation position 312a of the first placement area runs along the second axial direction. In this way, the first pipeline branch 41a can be more closely fitted to the surface of the first platform portion 21011 and the surface of the second platform portion 21013, thereby improving the installation stability of the first pipeline branch 41a. At the same time, the first pipeline branch 41a will not bend in the first installation position 311a of the first placement area and the second installation position 312a of the first placement area, thereby shortening the length of the bent portion of the first pipeline branch 41a and reducing the length of the first pipeline branch 41a. The fluid flow resistance in the branch 41a; at the same time, after the first pipeline branch 41a extends out of the first installation position 311a of the first placement area along the second axial direction, it is convenient to bend to one side on the first axial direction and enter the third installation position 313a of the first placement area, which can increase the bending angle of the pipeline branch 41 between the first installation position 311a of the first placement area and the third installation position 313a of the first placement area, and correspondingly, the bending angle of the pipeline branch 41 between the third installation position 313a of the first placement area and the second installation position 312a of the first placement area can also be increased, thereby facilitating the operator to install the first pipeline branch 41a.

[0158] Correspondingly, the pipeline corresponding to the first installation position 311b of the second placement area runs along the second axial direction, and the pipeline corresponding to the second installation position 312b of the second placement area runs along the second axial direction, which also improves the installation stability of the second pipeline branch 41b, shortens the length of the bending part of the second pipeline branch 41b, reduces the fluid flow resistance in the second pipeline branch 41b, and facilitates the operator to install the second pipeline branch 41b.

[0159] As mentioned above, the plurality of pipeline branches 41 further include a third pipeline branch, and the placement area of ​​the third pipeline branch includes a portion of the first platform portion 21011 .

[0160] Combination Figure 8 and Fig. 9 As shown, the fluid drive device 100 further includes a motor support assembly 5, and the motor 11 is fixed to the inclined portion 21012 through the motor support assembly 5. In this way, the motor 11 is indirectly fixed to the inclined portion 21012 through the motor support assembly 5, which facilitates the installation and fixing of the motor 11.

[0161] The specific structure of the motor support assembly 5 is selected according to actual conditions. In some embodiments, the motor support assembly 5 includes: a support inclined plate 51, a support top plate 52 fixedly connected to the top of the support inclined plate 51, and a support bottom plate 53 fixedly connected to the bottom of the support inclined plate 51; wherein the support inclined plate 51 is provided with a through hole 5101 through which the power supply machine 11 passes, the motor 11 is fixed to the support inclined plate 51, the support top plate 52 is fixed to the first platform part 21011 or the inclined part 21012, and the support bottom plate 53 is fixed to the second platform part 21013 or the inclined part 21012. In this way, the structure of the motor support assembly 5 is adapted to the structure of the drive upper shell 2101, which facilitates the fixed connection between the motor support assembly 5 and the drive upper shell 2101; moreover, it can be achieved that at least two of the inclined part 21012, the first platform part 21011 and the second platform part 21013 of the drive upper shell 2101 are fixedly connected to the motor support assembly 5, thereby improving the reliability of the connection between the motor support assembly 5 and the drive upper shell 2101.

[0162] As mentioned above, the flushing pump 1 of the fluid drive device is multiple, combined with Figure 2 , Figure 7 and Fig.10 As shown, at least two flushing pumps 1 can be selected to be distributed in sequence along the second axial direction, and the control module 6 is provided with a radiator 62, which is located between the motors 11 of two adjacent flushing pumps 1 in the second axial direction. In this way, the space between the motors 11 of two adjacent flushing pumps 1 in the second axial direction is fully utilized, the compactness of the structure of the fluid drive device is improved, and the volume of the fluid drive device is reduced.

[0163] As mentioned above, the fluid driving device 100 is placed on the console 200. Figure 2 , Figure 6 , Figure 10-12 and Fig. 22 As shown, in some embodiments, the console 200 includes an inclined back plate 201 and a base 202, and a placement space for accommodating the fluid drive device 100 is formed between the inclined back plate 201 and the base 202. The fluid drive device 100 includes an inclined rear wall 2106, a bottom wall 2105, and a cable fixing structure 9. As described above, the fluid drive device 100 also includes a control module 6.

[0164] The inclined rear wall 2106 is in contact with the inclined back plate 201, and at least a portion of the bottom wall 2105 is in contact with the base 202. It should be noted that the bottom wall 2105 and the inclined rear wall 2106 are both wall surfaces of the driving bottom shell 2102.

[0165] A cable fixing structure 9 is provided on one side of the bottom wall 2105 in the first axial direction, and the cable fixing structure 9 has a wire passing hole 924. A control module 6 is provided on the other side of the bottom wall 2105 in the first axial direction. In the first axial direction, the installation width d of the cable fixing structure 9 and the control module 6 combined is greater than the installation width e of the base 202. The bottom wall 2105 includes a connected horizontal portion and a tilted portion, and the installation width e of the base 202 is equal to the width f of the horizontal portion of the bottom wall 2105. In this way, without changing the installation width e of the base 202 and the width f of the horizontal portion of the bottom wall 2105, the compactness of the structure of the fluid driving device 100 is improved, which is conducive to reducing the volume of the fluid driving device 100.

[0166] It should be noted that the drive cable 8 is connected to the control module 6 and passes through the cable hole 924 to be connected to the interface of the console 200 .

[0167] As mentioned above, in the first axial direction, the installation width d of the combined assembly of the cable fixing structure 9 and the control module 6 is greater than the installation width e of the base 202. In order to minimize the installation width d of the combined assembly of the cable fixing structure 9 and the control module 6, the installation area of ​​the cable fixing structure 9 and the installation area of ​​the control module 6 can be selected to have an overlapping area in the first axial direction. In order to achieve partial overlap of the installation area of ​​the cable fixing structure 9 and the installation area of ​​the control module 6 in the first axial direction, the control module 6 is provided with a first recessed portion 61, and a yielding area formed by the first recessed portion 61, and a part of the cable fixing structure 9 is located in the yielding area. In this way, the installation areas of the cable fixing structure 9 and the control module 6 partially overlap in the first axial direction, which can reduce the installation width d of the combined assembly of the cable fixing structure 9 and the control module 6, so as to facilitate the installation of the control module 6 and the cable fixing structure 9.

[0168] Since the control module 6 is provided with the first recessed portion 61, the width of the control module 6 in the first axial direction is reduced. In order to ensure that there is sufficient circuit design space on the control module 6, the control module 6 may also be provided with a first protruding portion 63, so that the width of the control module 6 in the first axial direction is guaranteed to remain unchanged or change slightly. In order to accommodate the first protruding portion 63, the inclined rear wall 2106 is provided with a second protruding portion 21061, which protrudes toward the outside of the inclined rear wall 2106, and is used to accommodate the first protruding portion 63. In this way, the inclined rear wall 2106 provides a space for accommodating the control module 6, which can effectively improve the structural compactness of the fluid drive device 100 and reduce the volume of the fluid drive device 100.

[0169] In actual situations, other methods may be selected to achieve that the installation width d of the combined assembly of the cable fixing structure 9 and the control module 6 is greater than the installation width e of the base 202. This embodiment of the present application does not limit this.

[0170] In the fluid driving device 100, the control module 6 is connected to the console 200 via a driving cable 8. The shaking of the driving cable 8 will cause unstable signal transmission and affect the performance of the fluid driving device 100. Therefore, in order to improve the stability of signal transmission, there is a need to firmly fix the driving cable 8, and the more firmly the driving cable 8 is fixed, the better.

[0171] like Figure 10-Figure 16 As shown, the fluid driving device 100 further includes a cable bracket 7, which is placed on the cable fixing structure 9, and the cable bracket 7 is used to fix the driving cable 8 between the control module 6 and the console 200. In this way, the driving cable 8 is fixed by the cable bracket 7, which improves the firmness of the driving cable 8 and reduces the shaking degree of the driving cable 8, thereby improving the stability of signal transmission and the reliability of the connection between the control module 6 and the console 200; it is also convenient for the driving cable 8 to extend from the control module 6 to the console 200, that is, it is convenient for the driving cable 8 to be routed.

[0172] In some embodiments, the cable bracket 7 includes a first bracket 71 and a second bracket 72; the cable fixing structure 9 includes a first protrusion 91 and a second protrusion 92 protruding toward the inner side of the bottom wall 2105, and the first protrusion 91 is closer to the control module 6 than the second protrusion 92; the second bracket 72 and the second protrusion 92 are connected, the first bracket 71 is located above the second bracket 72, and the two ends of the first bracket 71 are respectively placed on the first protrusion 91 and the second protrusion 92, and the first bracket 71 and the second bracket 72 are spliced ​​up and down to fix the drive cable 8 between the control module 6 and the console 200.

[0173] The first convex body 91 and the second convex body 92 protrude from the bottom wall 2105 itself to the inner side of the bottom wall 2105. On the inner side of the bottom wall 2105, that is, inside the drive housing 2, the surface of the first convex body 91 includes the first convex body top wall 911 and the first convex body side wall 912, and the surface of the second convex body 92 includes the second convex body top wall 921 and the second convex body side wall 922. The second bracket 72 can be fixed on the surface of the second convex body 92, such as the second convex body top wall 921 and / or the second convex body side wall 922. The first bracket 71 can be fixed to the first convex body top wall 911 and the second convex body side wall 922, or can be fixed to the first convex body top wall 911 and the second convex body top wall 921, etc. As described above, the cable fixing structure 9 is provided with a wire hole 924, and the wire hole 924 can be provided on the second convex body top wall 921 of the second convex body 92.

[0174] In the above embodiment, the cable bracket 7 includes two parts, a first bracket 71 and a second bracket 72. The first bracket 71 and the second bracket 72 are spliced ​​up and down to fix the drive cable 8 between the control module 6 and the console 200. In this way, the second bracket 72 can be installed first, and then the drive cable 8 can be placed on the cable fixing structure 9 and the second bracket 72, and the drive cable 8 can be passed through the wire hole 924, and then the first bracket 71 can be installed. In this way, compared with the drive cable 8 directly passing through the round hole, it is convenient to route the drive cable 8, thereby facilitating the fixing of the drive cable 8; the end of the drive cable 8 has a connector, and the connector is usually larger than the cable diameter of the drive cable 8. If the drive cable 8 directly passes through the round hole, the round hole is larger due to the influence of the connector, resulting in a poor limiting effect on the drive cable 8. In this case, the first bracket 71 and the second bracket 72 are spliced ​​up and down to fix the drive cable, which will not be affected by the connector, and the hole for the drive cable 8 to pass through can be smaller, thereby improving the limiting effect on the drive cable 8; at the same time, the second bracket 72 is installed first and then the first bracket 71, and the first bracket 71 and the second bracket 72 are spliced ​​up and down, which facilitates the connection between the first bracket 71 and the second bracket 72, and then facilitates the fixing of the drive cable 8.

[0175] In order to facilitate the cable bracket 7 to fix the drive cable 8, a first semicircular hole 7105 can be provided on the side of the first bracket 71 away from the control module 6 along the first axis, and a second semicircular hole 7201 can be provided on the side of the second bracket 72 away from the control module 6 along the first axis. The first semicircular hole 7105 and the second semicircular hole 7201 are spliced ​​to form a first wire hole for the drive cable 8 to pass through. In this way, the cable bracket 7 is provided with a first wire hole on the side away from the control module 6, and the first wire hole limits the drive cable 8, which facilitates the drive cable 8 to pass through the wire hole 924; at the same time, the first semicircular hole 7105 and the second semicircular hole 7201 are spliced ​​to form the first wire hole. During the installation process, the drive cable 8 needs to be placed in the second semicircular hole 7201 first. In this way, the semicircular structure of the second semicircular hole 7201 can effectively limit the drive cable 8, thereby reducing the degree of shaking of the drive cable 8 in the second semicircular hole 7201 during the installation of the first bracket 71, thereby facilitating the fixing of the drive cable 8; moreover, the first semicircular hole 7105 and the second semicircular hole 7201 are spliced ​​to form the first wire hole. This structure also has the technical effect brought about by the splicing mentioned above, which will not be repeated here.

[0176] In order to facilitate the cable bracket 7 to fix the drive cable 8, it is also possible to select that the first bracket 71 is provided with an arched mounting portion 7101 on one side close to the control module 6 along the first axial direction, and the first convex body 91 is provided with a cable support portion 913. For example, the cable support portion 913 is arranged on the top wall 911 of the first convex body; when the first bracket 71 is fixedly connected to the first convex body 91 up and down, the arched mounting portion 7101 and the cable support portion 913 are spliced ​​to form a second through hole for the drive cable 8 to pass through. In this way, the cable bracket 7 is provided with a second through hole on the side close to the control module 6, and the second through hole limits the drive cable 8, thereby reducing the shaking degree of the part of the drive cable 8 connected to the control module 6, and effectively improving the connection stability of the drive cable 8 and the control module 6; moreover, the arched mounting portion 7101 and the cable support portion 913 are spliced ​​to form the second through hole, and this structure also has the technical effect brought about by the splicing mentioned above, which will not be repeated here.

[0177] It should be noted that the arched mounting portion 7101 is arched, and the arched mounting portion 7101 has a first recessed groove, and the cable support portion 913 has a second recessed groove. After the arched mounting portion 7101 and the cable support portion 913 are spliced, the first recessed groove and the second recessed groove are spliced ​​to form the above-mentioned second through-line hole. The arched mounting portion 7101 can be one or more than two. When there are more than two arched mounting portions 7101, any two arched mounting portions 7101 are sequentially distributed along the axial direction of the second through-line hole. Correspondingly, the cable support portion 913 can be one or more than two. When there are more than two cable support portions 913, any two cable support portions 913 are sequentially distributed along the axial direction of the second through-line hole.

[0178] In actual situations, the first wire hole and the second wire hole can be set at the same time. In this way, the fixing effect of the drive cable 8 is improved, and it is also convenient to control the direction of the drive cable 8. When the first wire hole and the second wire hole are set at the same time, the second wire hole is located between the first wire hole and the control module 6, and the first wire hole is lower than the second wire hole. In this way, the first wire hole and the second wire hole constrain the two positions of the drive cable 8, which is convenient for controlling the direction of the drive cable 8, so that the installation is convenient for the drive cable 8.

[0179] The specific structure of the cable bracket 7 and the connection structure between the cable bracket 7 and the cable fixing structure 9 will be described below.

[0180] In the embodiment of the present application, the first bracket 71 includes: an arched mounting portion 7101, a crossbeam 7103, an inclined beam 7104 and a flat mounting portion 7102; wherein one end of the crossbeam 7103 is connected to the arched mounting portion 7101, the other end of the crossbeam 7103 is connected to the bottom end of the inclined beam 7104, and the top end of the inclined beam 7104 is connected to the flat mounting portion 7102; the first semicircular hole 7105 is provided on the inclined beam 7104, and the arched mounting portion 7101 and the flat mounting portion 7102 are both installed on the second convex body 92; the second bracket 72 is located at the bottom side of the crossbeam 7103. In this way, it is convenient for the first bracket 71 and the second bracket 72 to form a first through hole, and it is also convenient for the first bracket 71 to be placed on the first convex body 91 and the second convex body 92.

[0181] In order to facilitate the installation of the first bracket 71, the first convex body top wall 911 of the first convex body 91 is provided with a first fixing column 914, and the two ends of the arched mounting portion 7101 are provided with mounting columns 7108, and the mounting columns 7108 and the first fixing columns 914 correspond to each other and are fixedly connected by fasteners. It should be noted that the mounting columns 7108 and the first fixing columns 914 are both hollow structures, that is, the mounting columns 7108 and the first fixing columns 914 are both provided with fixing holes. In order to facilitate installation, one of the mounting columns 7108 and the first fixing columns 914 is covered with the other, so that the mounting columns 7108 and the first fixing columns 914 can also guide each other, thereby facilitating the installation of the first bracket 71. Of course, the mounting columns 7108 and the first fixing columns 914 can be selected to be docked, and the embodiment of the present application does not limit this.

[0182] As mentioned above, the first protrusion 91 is provided with a cable support portion 913 . In order to improve the firmness of fixing the driving cable 8 , the cable support portion 913 may be selected to be located between the two first fixing columns 914 .

[0183] A second fixing column 923 is disposed on the second protrusion side wall 922 of the second protrusion 92, and the flat plate mounting portion 7102 and the second fixing column 923 are fixedly connected by a fastener.

[0184] As mentioned above, the second protrusion 92 is provided with a wire hole 924 . To facilitate wiring, the wire hole 924 can be selected to be located between the second fixing column 923 and the first fixing column 914 .

[0185] In the first bracket 71, two first limiting plates 7106 arranged side by side are provided at the connection of the cross beam 7103 and the inclined beam 7104, and the two first limiting plates 7106 are used to limit the driving cable 8; two second limiting plates 7107 arranged side by side are provided at the connection of the cross beam 7103 and the arched mounting portion 7101, and the two second limiting plates 7107 are used to limit the driving cable 8. In this way, part of the driving cable 8 is located between the two second limiting plates 7107, and part of the driving cable 8 is located between the two first limiting plates 7106, and the first limiting plates 7106 and the second limiting plates 7107 constrain the direction of the driving cable 8, so that the driving cable 8 can pass through the first wire hole.

[0186] The first bracket 71 may be one component, that is, all components in the first bracket 71 are an integrated structure; or, in the first bracket 71, at least two components are a split structure, which is not limited in the embodiment of the present application.

[0187] In actual situations, the first bracket 71 may also be selected to have other structures and is not limited to the above embodiment.

[0188] In the embodiment of the present application, the second bracket 72 includes: a third limiting plate 7202 , a connecting transverse plate 7203 , a mounting plate 7204 , a fourth limiting plate 7205 and a second clamping plate 7206 .

[0189] The third limiting plate 7202 is connected to the first bracket 71 in a limiting manner, wherein a limiting rib 7109 is provided on the bottom side of the crossbeam 7103 of the first bracket 71, and the limiting rib 7109 and the third limiting plate 7202 are matched in a limiting manner. For example, there is one limiting rib 7109, there are two third limiting plates 7202, and the two third limiting plates 7202 are matched in a limiting manner with both sides of the limiting rib 7109; or, there are two limiting ribs 7109, there are two third limiting plates 7202, the two third limiting plates 7202 are limited on both sides of the two limiting ribs 7109, or the two third limiting plates 7202 are limited between the two limiting ribs 7109. On this basis, the number of limiting ribs 7109 and the third limiting plates 7202 can be adjusted, and this embodiment of the present application does not limit this.

[0190] Since the limiting rib 7109 and the third limiting plate 7202 cooperate with each other in a limiting manner, the second bracket 72 can be prevented from sliding relative to the first bracket 71 , thereby improving the stability of the second bracket 72 .

[0191] The upper part of the connecting transverse plate 7203 is fixedly connected to the third limiting plate 7202, the lower part of the connecting transverse plate 7203 is fixedly connected to the fourth limiting plate 7205, one side of the connecting transverse plate 7203 is fixedly connected to the mounting plate 7204, the second clip plate 7206 is fixedly connected to the mounting plate 7204, and the second clip plate 7206 can also be fixedly connected to the connecting transverse plate 7203 and / or the fourth limiting plate 7205.

[0192] In order to facilitate the connection between the second bracket 72 and the cable fixing structure 9, the second clamping plate 7206 and the second protrusion 92 are clamped. Specifically, there are at least two second clamping plates 7206 and they are distributed on both sides of the mounting plate 7204. The second clamping plate 7206 is clamped on the second protrusion side wall 922 of the second protrusion 92. In this way, the second protrusion 92 does not need to have a separate clamping structure, which simplifies the structure of the second protrusion 92.

[0193] In order to improve the stability of the second bracket 72, the fourth limiting plate 7205, the connecting cross plate 7203 and the side of the third limiting plate 7202 away from the mounting plate 7204 are all against the first protrusion side wall 912 of the first protrusion 91, and the other side of the fourth limiting plate 7205 is against the second protrusion top wall 921. In this way, part of the structure of the second bracket 72 can be limited between the first protrusion 91 and the second protrusion 92, which facilitates the fixing of the second bracket 72 and improves the stability of the second bracket 72.

[0194] As mentioned above, the second bracket 72 is provided with a second semicircular hole 7201 , and the second semicircular hole 7201 can be provided on the mounting plate 7204 . The two second clamping plates 7206 are distributed on both sides of the second semicircular hole 7201 .

[0195] In the above-mentioned second bracket 72, the two third limiting plates 7202 can also limit the driving cable 8, so that the third limiting plates 7202 restrict the direction of the driving cable 8, making it easier for the driving cable 8 to pass through the first cable hole.

[0196] In the embodiment of the present application, during the installation process, the second bracket 72 is first placed directly on the second protrusion 92, so that the second clamping plate 7206 of the second bracket 72 is clamped with the second protrusion side wall 922, and part of the structure of the second bracket 72 is limited between the first protrusion 91 and the second protrusion 92; then the drive cable 8 is passed through the cable support portion 913 and the second semicircular hole 7201 in sequence and through the wire hole 924; then the first bracket 71 is placed on the first protrusion 91 and the second protrusion 92, so that the first bracket 71 and the second bracket 72 are limited and matched and spliced; finally, the first bracket 71 and the first protrusion 91, as well as the first bracket 71 and the second protrusion 92 are fixedly connected. In this way, the first bracket 71 and the cable fixing structure 9 are fixedly connected to achieve the first bracket 71 and the cable fixing structure 9 clamping and fixing the second bracket 72, which simplifies the installation of the second bracket 72, thereby simplifying the installation of the entire cable bracket 7.

[0197] In actual situations, the second bracket 72 may also be other structures and is not limited to the above embodiments.

[0198] As mentioned above, the flushing pump 1 of the fluid drive device 100 is installed at the inclined portion 21012. In the case of using the casing of other equipment as the drive casing 2, the width g of the drive casing 2 at its inclined portion 21012 is limited, and the thickness direction of the drive casing 2 at its inclined portion 21012 is the first axial direction. In order to ensure that the flushing pump 1 is installed in a limited space, it is necessary to reduce the size of the flushing pump 1 as much as possible, especially the size (motor height) of the motor 11 of the flushing pump 1. In addition, the control module 6 needs to be placed on the bottom side of the motor 11 of the flushing pump 1. In order to avoid interference between the motor 11 and the control module 6, it is also necessary to reduce the size (motor height) of the motor 11.

[0199] In some embodiments, Figure 17-Figure 20 As shown, the flushing pump 1 also includes: a motor bottom cover 12, a grating toothed disc 1301 and a grating sensor 1302. It should be noted that the grating toothed disc 1301 and the grating sensor 1302 can be understood as part of the speed sensor 13. In actual situations, the speed sensor 13 can also be of other types, which is not limited in the embodiment of the present application.

[0200] In the flushing pump 1, the motor 11 includes a rotating shaft and a motor bottom wall 1101, the rotating shaft extends from the motor bottom wall 1101 and is connected to the grating toothed disk 1301. In order to facilitate the connection between the rotating shaft and the grating toothed disk 1301, the grating toothed disk 1301 can be connected to the rotating shaft through a bearing 15 to ensure that the rotating shaft and the grating toothed disk 1301 rotate synchronously.

[0201] The grating sensor 1302 includes a first end 13021 and a second end 13022, and a gap is provided between the first end 13021 and the second end 13022 to accommodate the grating toothed disk 1301; the motor bottom cover 12 is connected to the motor bottom wall 1101, and the motor bottom cover 12 has a notch; the grating sensor 1302 is inserted into the notch to form a closed space to cover the grating toothed disk 1301. In this way, the grating sensor 1302 is externally arranged, and the motor bottom cover 12 and the grating sensor 1302 jointly form a closed space, and the motor bottom cover 12 does not need to completely surround the speed sensor 13 (the part of the motor bottom cover 12 surrounding the grating sensor 1302), so the size of the motor bottom cover 12 is reduced, and the volume of the entire flushing pump 1 is effectively reduced.

[0202] Furthermore, the distance between the bottom end of the motor bottom cover 12 and the motor bottom wall 1101 is less than or equal to the distance between the bottom end of the grating sensor 1302 and the motor bottom wall 1101. In this way, the size of the motor bottom cover 12 in the axial direction of the motor 11 is reduced, thereby reducing the volume of the flushing pump 1; at the same time, the bottom side of the bottom end of the motor bottom cover 12 can accommodate other components, such as components of the control module 6, etc., thereby improving the structural compactness of the fluid drive device 100.

[0203] In some embodiments, the grating sensor 1302 further includes a sensor fixing portion 13023, and the motor bottom cover 12 includes a sensor mounting portion; when the grating sensor 1302 is inserted into the notch, the sensor fixing portion 13023 and the sensor mounting portion are fixedly connected, and the sensor fixing portion 13023 is located on a side of the sensor mounting portion away from the motor bottom wall 1101. In this way, it is convenient to fix the grating sensor 1302 and the motor bottom cover 12, to facilitate the assembly of the grating sensor 1302, and to ensure that: the distance between the bottom end of the motor bottom cover 12 and the motor bottom wall 1101 is less than or equal to the distance between the bottom end of the grating sensor 1302 and the motor bottom wall 1101.

[0204] The shape and structure of the motor bottom cover 12 are selected according to actual conditions. In some embodiments, the motor bottom cover 12 includes: a first bottom cover bottom plate 1201, a second bottom cover bottom plate 1202 and a bottom cover side plate 1203; wherein the first bottom cover bottom plate 1201 is located at the periphery of the second bottom cover bottom plate 1202, and the second bottom cover bottom plate 1202 is farther away from the motor 11 than the first bottom cover bottom plate 1201, and the bottom cover side plate 1203 connects the first bottom cover bottom plate 1201 and the second bottom cover bottom plate 1202; the first bottom cover bottom plate 1201 is fixedly connected to the motor 11, and the grating sensor 1302 is fixedly connected to the second bottom cover bottom plate 1202.

[0205] Of course, the motor bottom cover 12 may also be selected to have other structures, which is not limited in the embodiment of the present application.

[0206] like Fig.21As shown, in the fluid drive device 100, there are two flushing pumps 1, and the two flushing pumps 1 are symmetrically arranged. In the case where the flushing pump 1 includes a speed sensor 13, the flushing pump 1 also includes a connector 14, and the motor drive line of the motor 11 and the sensor drive line of the speed sensor 13 are both connected to the connector 14, and the connector 14 is also used to connect to the control module 6. In order to facilitate wiring, the speed sensors 13 of the two flushing pumps 1 can be symmetrically arranged, and the connectors 14 of the two flushing pumps 1 can be symmetrically arranged.

[0207] In the above structure, each flushing pump 1 has one connector 14, and the motor 11 and the speed sensor 13 share one connector 14, so that the control module 6 can use only one wiring harness to control the motor 11 and the speed sensor 13 at the same time, which simplifies the structure and the wiring. Of course, it is also possible to choose to have two connectors 14 for each flushing pump 1, and the motor 11 and the speed sensor 13 are connected to the control module 6 using one connector 14 respectively.

[0208] In the fluid drive device 100, the drive housing 2 is provided with at least one direction mark, and the direction mark is used to indicate the fluid delivery direction in at least one pipeline branch 41. In this way, it is convenient to install the flushing pipeline 4B and the flushing pump 1.

[0209] The specific type and number of direction indicators, for example, the direction indicator is an arrow indicator, are selected according to actual conditions and are not limited in this embodiment of the present application.

[0210] As described above, the control device 1B provided in the embodiment of the present application includes the above-mentioned fluid driving device 100 and the above-mentioned console 200. Since the above-mentioned fluid driving device 100 has the above-mentioned technical effects, the above-mentioned control device 1B also has corresponding technical effects, which will not be repeated here.

[0211] like Fig. 22 As shown, in some embodiments, the console 200 is provided with a second recessed portion 203. As described above, the console 200 includes an inclined back plate 201 and a base 202, and the second recessed portion 203 is located at the inclined back plate 201. The console 200 has a first state for application to an extracorporeal magnetic levitation artificial heart, and a second state for application to an invasive artificial heart; in the first state, the second recessed portion 203 is used to accommodate a magnetic levitation motor; in the second state, the second recessed portion 203 is used to accommodate a second protrusion 21061 of the inclined rear wall 2106 of the fluid drive device 100.

[0212] When the second recess 203 accommodates the second protrusion 21061, part or all of the first protrusion 63 of the control module 6 is located within the area of ​​the second recess 203, so that the first recess 61 of the control module 6 can make way for the cable fixing structure 9, thereby fixing the control module 6 and the cable fixing structure 9 on the bearing plane formed by the base 202 at the same time, achieving partial overlap of the installation areas of the cable fixing structure 9 and the control module 6 in the first axial direction, and reducing the installation width d of the combined assembly of the cable fixing structure 9 and the control module 6, so as to facilitate the installation of the control module 6 and the cable fixing structure 9.

[0213] Since the control module 6 is provided with the first recessed portion 61, the width of the control module 6 in the first axial direction is reduced. In order to satisfy the requirement of sufficient circuit design space on the control module 6, the control module 6 may also be provided with a first protruding portion 63, so that the width of the control module 6 in the first axial direction can be ensured to remain unchanged or change slightly. In order to accommodate the first protruding portion 63, the inclined rear wall 2106 is provided with a second protruding portion 21061, which protrudes toward the outside of the inclined rear wall 2106, and the second protruding portion 21061 is used to accommodate the first protruding portion 63. In this way, the inclined rear wall 2106 provides a space for accommodating the control module 6, which can effectively improve the compactness of the structure of the fluid driving device 100 and reduce the volume of the fluid driving device 100, and there is no need to modify the device structure of the console 200.

[0214] In this way, the console 200 can be adapted to both the magnetic levitation motor and the fluid drive device 100, thereby improving the adaptability of the console 200; at the same time, the extracorporeal magnetic levitation artificial heart and the interventional artificial heart can use the same console 200 (i.e., the above-mentioned console 200), thereby reducing the types of consoles 200 and reducing R&D costs.

[0215] As described above, the transcatheter ventricular assist device provided in the embodiment of the present application includes the above-mentioned fluid driving device 100. Since the above-mentioned fluid driving device 100 has the above-mentioned technical effects, the above-mentioned transcatheter ventricular assist device also has corresponding technical effects, which will not be repeated here.
