A VAVD consists of a control unit and an interventional pump system used in conjunction with the control unit. The control unit primarily includes a console, an interventional pump drive unit, and a fluid drive unit. The fluid drive unit houses the flushing tubing and the flushing pump. The fluid drive unit controls the flushing pump, and the flushing tubing and pump work together to deliver flushing fluid, preventing blood from entering the interventional pump catheter and causing thrombosis, thus ensuring patient safety.

Detailed Implementation

[0084] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0085] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to limit the scope of this disclosure. As used in the specification and appended claims of this disclosure, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the embodiments of this disclosure, “one or more” refers to one, two, or more than two; “and / or” describes the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0086] The term "multiple" in this disclosure refers to two or more embodiments. It should be noted that in the description of the embodiments in this disclosure, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance, nor as indicating or implying order.

[0087] The terms "parallel" and "perpendicular" used in this disclosure refer to "basically parallel" and "basically perpendicular" in actual operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.

[0088] The “plane” mentioned in this disclosure refers to a “plane that is substantially parallel to the horizontal plane” in actual operation.

[0089] This disclosure provides a fluid handling device, a control device, and a transcatheter ventricular assist device to prevent the various branches of the flushing pipeline from becoming entangled, making it easier for operators to install the flushing pipeline and reducing the installation error rate of the flushing pipeline.

[0090] For ease of explanation, the transcatheter ventricular assist device provided in the embodiments of this disclosure will be described first.

[0091] A transcatheter ventricular assist device (TAVED) includes a control unit (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 support for patients with relevant indications. Users can monitor the system status and patient physiological parameters on the control host interface and adjust the speed of the interventional pump to provide different levels of circulatory support according to the patient's needs, thereby temporarily maintaining blood circulation to the patient's vital organs and relieving the burden on the heart.

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

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

[0094] The delivery system mainly consists of a dilator, an interventional sheath, and a delivery device. The system dilates blood vessels and provides access for the interventional pump to be inserted into the heart. The delivery device and interventional sheath function to retract the pump head. The delivery device and dilator are removed after the interventional pump is in place. The interventional sheath remains in the patient's blood vessel until the interventional pump is removed; during removal, the sheath continues to retract the pump head.

[0095] The flushing tubing includes a flushing kit and an arterial pressure monitoring kit, with a flushing pump installed on the flushing kit. The flushing pump is driven by a fluid drive unit in the control unit, which pumps the flushing fluid into the interventional pump, thus preventing blood from entering the interventional pump drive catheter. The fluid drive unit can be understood as the flushing pump drive unit.

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

[0097] The interventional pump drive unit 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 a knob on the control panel. During operation, if any high-risk situation occurs, the interventional pump drive unit will send an alarm signal to the control panel.

[0098] The console provides users with a simple and intuitive operating interface, enabling the following functions: monitoring the operating status of the transcatheter ventricular assist device; displaying system operating status and patient physiological data, including rotational speed, blood pressure, and flow rate; controlling the rotational speed of the drive motor and flushing pump; supporting the setting of alarm thresholds and system parameters; the console provides different levels of alarms and automatically records various alarm information, with relevant charts displayed in the summary report.

[0099] In the aforementioned transcatheter ventricular assist device, after the drive catheter handle, flushing tubing, and fluid drive device are connected, a flushing channel is formed. The drive catheter handle includes a drive catheter flushing tubing inlet connector, a drive catheter flushing tubing outlet connector, an arterial pressure measurement tubing inlet connector, and an arterial pressure measurement tubing outlet connector.

[0100] The inlet and outlet connectors of the drive catheter flushing line are connected to the flushing tubing in the flushing kit. The inlet connector of the arterial pressure measurement line is connected to the tubing of the arterial pressure measurement kit (arterial pressure measurement line). The flushing fluid is connected to the pressure measurement interface of the interventional sheath via the outlet connector of the arterial pressure measurement line. The gap between the interventional sheath and the drive catheter, and the connection between the drive catheter handle and the arterial pressure measurement line, form the arterial pressure measurement pathway.

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

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

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

[0104] In some other embodiments, the console 200 may be selected to have only the status applicable to the interventional artificial heart.

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

[0106] In practice, the fluid drive device 100 may not be installed on the control console 200, for example, the fluid drive device 100 may be installed separately.

[0107] The fluid drive device 100 provided in the embodiments of this disclosure is described in detail below.

[0108] As shown in Figure 2, the fluid driving device 100 provided in this embodiment of the present disclosure is used to drive fluid in the flushing line 4B into an interventional device (e.g., an interventional pump), and the flushing line 4B includes a line branch 41.

[0109] The fluid drive device 100 includes a placement area 3, which corresponds to a pipeline branch 41. The placement area 3 has at least three mounting positions 31 arranged in a first axial direction. As shown in Figure 2, the mounting positions 31 can be grooves. In practice, the mounting positions 31 can also be structures or holes with clamping portions on both sides. The mounting positions 31 can be directly formed from the drive housing 2 of the fluid drive device 100; the mounting positions 31 can also be relatively independent from the drive housing 2, and the mounting positions 31 can be set on the drive housing 2 by means of bonding, snap-fitting, welding, etc.; the mounting positions 31 can also be the part of the flushing pump that clamps the pipeline.

[0110] The structures of all mounting positions 31 arranged along the first axis can be the same or different. For example, as shown in FIG2, there are three mounting positions 31 arranged along the first axis in the first placement area 3a, namely the first mounting position 311a, the second mounting position 312a, and the third mounting position 313a of the first placement area; wherein, the first mounting position 311a 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 of the flushing pump 1 (injection pump 1a) that holds the pipeline. In the second placement area 3b, there are three mounting positions 31 arranged along the first axis, namely the first mounting position 311b, the second mounting position 312b, and the third mounting position 313b of the second placement area; wherein, the first mounting position 311b 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 of the flushing pump 1 (circulation pump 1b) that holds the pipeline.

[0111] Pipe branches 41 are sequentially installed at at least three mounting positions 31, connected in an adjacent inlet / outlet sequence. These adjacent mounting positions refer to those adjacent along the first axial direction within each placement area. For example, the first mounting position 311a and the third mounting position 313a of the first placement area are adjacent mounting positions, as are the second mounting position 312a and the third mounting position 313a. The fluid outlet of one adjacent mounting position and the fluid inlet of the other are located on the same side of the second axial direction, where the first and second axial directions intersect. Within their corresponding placement areas 3, the pipe branches 41 exhibit an S-shaped wavy curve.

[0112] For example, as shown in Figure 2, taking the right and left sides of the second axis as examples (the right and left sides shown in Figure 2 are just examples, and the right and left sides can be interchanged), the two pipe branches 41 are the first pipe branch 41a and the second pipe branch 41b, and there are two placement areas, namely 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, the second mounting position 312a 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, the second mounting position 312b and the third mounting position 313 of the second placement area. The first pipe branch 41a is installed in the first placement area 3a. Specifically, the first pipe branch 41a is installed in the first mounting position 311a, the second mounting position 312a, and the third mounting position 313a of the first placement area. The second pipe branch 41b is installed in the second placement area 3b. Specifically, the second pipe branch 41b is installed in the first mounting position 311b, the second mounting position 312b, and the third mounting position 313 of the second placement area.

[0113] The first pipe branch 41a extends from the first mounting position 311a in the first placement area to the left side of the second axis, enters the third mounting position 313a in the first placement area from the left side of the second axis and extends to the right side of the second axis, then enters the second mounting position 312a in the first placement area from the right side of the second axis and extends to the left side of the second axis, so that the first pipe branch 41a has a curved shape similar to an "S" shaped wave within its corresponding first placement area 3a. Of course, the first pipe branch 41a can also be installed in other ways, such as first installing the first pipe branch 41a in the second mounting position 312a of the first placement area, then installing it in the third mounting position 313a of the first placement area, and then installing it in the first mounting position 311a of the first placement area.

[0114] The second pipe branch 41b extends from the first mounting position 311b in the second placement area to the right side of the second axis, enters the third mounting position 313b in the second placement area from the right side of the second axis and extends to the left side of the second axis, then enters the second mounting position 312b in the second placement area from the left side of the second axis and extends to the right side of the second axis, so that the second pipe branch 41b has a curved shape similar to an "S" shaped wave within its corresponding second placement area 3b. Of course, the second pipe branch 41b can also be installed in other ways, such as first installing the second pipe branch 41b in the second mounting position 312b of the second placement area, then installing it in the third mounting position 313b of the second placement area, and finally installing it in the first mounting position 311b of the second placement area.

[0115] In the aforementioned fluid drive device, because the pipeline branch 41 has an "S"-shaped wavy curve within its corresponding placement area 3, the pipeline branch 41 is prevented from tangling or knotting. At the same time, this design facilitates the distribution of the pipeline branch 41, making it easier for operators to install the pipeline branch 41, reducing the installation error rate of the pipeline branch 41, and effectively reducing the installation time and error rate of the flushing pipeline 4B.

[0116] In the aforementioned fluid drive device, because the pipe branch 41 has an S-shaped wavy curve within its corresponding placement area 3, the fluid flow directions corresponding to adjacent installation positions 31 in at least three installation positions 31 in the placement area 3 are opposite. For example, as shown in FIG2, in the portion of the first pipe branch 41a at the second installation position 312a in the first placement area, the fluid flows from left to right; in the portion of the first pipe branch 41a at the third installation position 313a in the first placement area, the fluid flows from right to left; and in the portion of the first pipe branch 41a at the first installation position 311a in the first placement area, the fluid flows from left to right. Therefore, for the first placement area 3a, the fluid flow directions at the second installation position 312a and the third installation position 313a are opposite, and the fluid flow directions at the third installation position 313a and the first installation position 311a are opposite. The same applies to the second placement area 3b, which will not be elaborated further here.

[0117] It should be noted that the "S"-shaped wave curve can be understood as a serpentine wave curve. The "S"-shaped wave curve is not limited to the shape of the first pipeline branch 41a and the form of the second pipeline branch 41b shown in Figure 2.

[0118] Figure 3 shows four types of "S"-shaped wave curves. Combining Figures 2 and 3, the shape of the first pipeline branch 41a can also be the curved shape of the "S"-shaped wave curve shown in Figure 3(1), or the curved shape of the "S"-shaped wave curve shown in Figure 3(3); the shape of the second pipeline branch 41b can also be the curved shape of the "S"-shaped wave curve shown in Figure 3(2), or the curved shape of the "S"-shaped wave curve shown in Figure 3(4).

[0119] In practice, the “S”-shaped wave curve is not limited to the shape shown in Figures 2 and 3, and can also be other “S”-shaped wave curves. This disclosure does not limit this.

[0120] The number of pipe branches 41 in the flushing pipe 4B is multiple, and the number of placement areas 3 in the fluid drive device 100 is multiple. It should be noted that "multiple" means two or more.

[0121] At least some of the multiple pipe branches 41 correspond one-to-one with multiple placement areas 3, and the multiple placement areas 3 are arranged in the second axis.

[0122] It should be noted that at least some of the multiple pipe branches 41 correspond one-to-one with multiple placement areas 3. For example, the multiple pipe branches 41 may be three pipe branches 41, in which two pipe branches 41 correspond one-to-one with two placement areas 3; the multiple pipe branches 41 may be three pipe branches 41, in which three pipe branches 41 correspond one-to-one with three placement areas 3; the multiple pipe branches 41 may be four pipe branches 41, in which two pipe branches 41 correspond one-to-one with two placement areas 3.

[0123] In the above structure, at least some of the multiple pipe branches 41 can be located in different placement areas 3. Moreover, since the multiple placement areas 3 are arranged along the second axis, the multiple pipe branches 41 corresponding to the placement areas 3 can be arranged along the second axis, realizing the isolation between different pipe branches 41 and avoiding the different pipe branches 41 from getting tangled or knotted together. At the same time, each pipe branch 41 corresponding to the placement area 3 has a specific placement area 3, which facilitates the installation of each pipe branch 41 corresponding to the placement area 3 by the operator, reduces the probability of misalignment between multiple pipe branches 41, and effectively reduces the installation time and installation error rate of the flushing pipe 4B.

[0124] As can be seen from the above analysis, the fluid drive device provided in this embodiment can make each pipe branch 41 in the corresponding placement area 3 bend into an "S"-shaped wave curve within its corresponding placement area 3, effectively avoiding the entanglement and knotting between multiple pipe branches 41, as well as the entanglement and knotting of the pipe branches 41 themselves. At the same time, the distribution of the pipe branches 41 themselves and the distribution of each pipe branch 41 corresponding to the placement area 3 are planned, which facilitates the installation of the flushing pipe 4B by the operator and effectively reduces the installation time and installation error rate of the flushing pipe 4B.

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

[0126] For example, as shown in Figure 2, the pipe routing corresponding to the first mounting position 311a in the first placement area is along the second axis, the pipe routing corresponding to the second mounting position 312a in the first placement area is along the second axis, the pipe routing corresponding to the first mounting position 311b in the second placement area is along the second axis, and the pipe routing corresponding to the second mounting position 312b in the second placement area is along the second axis.

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

[0128] In the above embodiment, at least one mounting position 31 corresponds to a pipeline route along the second axial direction. This prevents the pipeline from bending in the mounting position 31, shortens the bending length of the pipeline branch 41, and reduces the fluid flow resistance within the pipeline branch 41. At the same time, the pipeline can extend out of the mounting position 31 along the second axial direction. The pipeline extending along the second axial direction can bend to one side of the first axial direction and enter another mounting position 31, which can increase the bending angle of the pipeline branch 41 between two adjacent mounting positions 31, thereby facilitating the operator to install the pipeline branch 41.

[0129] In practice, the direction of the pipe corresponding to the installation position 31 can be chosen to be relatively inclined to the second axis, or the direction of the pipe corresponding to the installation position 31 can be other directions. This embodiment does not limit this.

[0130] As mentioned above, the multiple placement areas 3 include a first placement area 3a and a second placement area 3b, and the multiple pipe branches 41 include a first pipe branch 41a and a second pipe branch 41b; wherein, the first pipe branch 41a is placed in the first placement area 3a, and the second pipe branch 41b is placed in the second placement area 3b. In order to ensure that the first pipe branch 41a has a bend shape similar to an "S" shaped wave curve in its corresponding first placement area 3a, and the second pipe branch 41b has a bend shape similar to an "S" shaped wave curve in its corresponding second placement area 3b, the bending shape of the first pipe branch 41a and the bending shape of the second pipe branch 41b can be selected to be axially symmetrical.

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

[0132] Taking the sequential installation of the first pipe branch 41a, the connector connecting the first pipe branch 41a and the second pipe branch 41b, and the second pipe branch 41b as an example, the first pipe branch 41a passes through the second mounting position 312a of the first placement area from left to right, bends to the left of the first placement area 3a and enters the third mounting position 313a of the first placement area, extending to the left of the first placement area 3a, and bends to the right of the first placement area 3a and enters the first mounting position 311a of the first placement area; the connector is installed; then the second pipe branch 41b is installed. Since the bending shape of the first pipe branch 41a and the bending shape of the second pipe branch 41b are axially symmetrical, the second pipe branch 41b is installed from the left to the right of the second placement area 3b in the first mounting position 311b of the second placement area, and extends from the right of the second placement area 3b. In this way, the first pipe branch 41a can be connected to the second pipe branch 41b. The pipes at the first mounting position 311a and the first mounting position 311b in the second placement area are arranged parallel or coaxially, reducing the bending of the flushing pipe 4B and thus reducing the fluid flow resistance within the flushing pipe 4B. The second pipe branch 41b extends from the right side of the second placement area 3b at the first mounting position 311b of the second placement area, bends to the left side of the second placement area 3b, and enters the third mounting position 313b of the second placement area. This increases the space for installing the second pipe branch 41b on the right side of the second placement area 3b, making it easier for operators to install the second pipe branch 41b. The second pipe branch 41b extends from the left side of the second placement area 3b at the third mounting position 313b of the second placement area, bends to the right side of the second placement area 3b, enters the first mounting position 311b of the second placement area, and extends out from the right side of the second placement area 3b.

[0133] Taking the installation of the communicating vessel first, followed by the installation of the first pipe branch 41a and the second pipe branch 41b as an example, after the communicating vessel is installed, the first pipe branch 41a extends to the left along the second axis, and the second pipe branch 41b extends to the right along the second axis. The first pipe branch 41a extends from the left side of the first placement area 3a to the first mounting position 311a of the first placement area. After bending to the right side of the first placement area 3a, the first pipe branch 41a enters the third mounting position 313a of the first placement area, and then extends from the right side of the first placement area 3a to the third mounting position 313a of the first placement area. The first pipe branch 41a extends towards the first placement area... After bending to the left, 3a enters the second mounting position 312a of the first placement area and extends from the left side of the first placement area 3a; the second pipe branch 41b extends from the right side of the second placement area 3b to the first mounting position 311b of the second placement area, bends to the left side of the second placement area 3b and enters the third mounting position 313b of the second placement area, then extends from the left side of the second placement area 3b to the third mounting position 313b of the second placement area, bends to the right side of the second placement area 3b and enters the second mounting position 312b of the second placement area and extends from the right side of the second placement area 3b. This avoids mutual interference between the installation of the first pipeline branch 41a and the second pipeline branch 41b, making it easier for operators 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. At the same time, it can realize that the pipelines in the first installation position 311a of the first placement area and the pipelines in the first installation position 311b of the second placement area are arranged in parallel or coaxially, reducing the occurrence of bends in the flushing pipeline 4B, thereby reducing the fluid flow resistance in the flushing pipeline 4B.

[0134] Based on the above, 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 makes it easier for operators to install the first pipeline branch 41a in the first installation position 311a in the first placement area and the second pipeline branch 41b in the first installation position 311b in the second placement area, thus facilitating the installation of the flushing pipeline 4B.

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

[0136] Of course, the bending shape of the first pipeline branch 41a can also be made 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 axially symmetrical, which means that the bending direction is axially symmetrical. For example, the bending shapes of the curves shown in Figure 3(1) and Figure 3(2) are axially symmetrical, the bending shapes of the curves shown in Figure 3(3) and Figure 3(4) are axially symmetrical, the bending shapes of the curves shown in Figure 3(1) and Figure 3(3) are consistent, and the bending shapes of the curves shown in Figure 3(2) and Figure 3(4) are consistent.

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

[0139] To facilitate the placement of the pipe branch 41 and effectively prevent the pipe branch 41 from tangling, a first mounting position can be selected for installing the end of the pipe branch 41 near the branch junction, a second mounting position can be selected for installing the end of the pipe branch 41 away from the branch junction, and a third mounting position can be selected between the first and second mounting positions in the first axial direction; wherein, the branch junction refers to the junction where multiple pipe branches 41 meet and connect.

[0140] For example, the first mounting position 311a of the first placement area is used to install the end of the first pipe branch 41a near the branch junction, the second mounting position 312a of the first placement area is used to install the end of the first pipe branch 41a away from the branch junction, and the third mounting position 313a of the first placement area is located between the first mounting position 311a 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 the end of the second pipe branch 41b near the branch junction, the second mounting position 312b of the second placement area is used to install the end of the second pipe branch 41b away from the branch junction, and the third mounting position 313b of the second placement area is located between the first mounting position 311b and the second mounting position 312b of the second placement area in the first axial direction; wherein, the branch junction refers to the junction of multiple first pipe branches 41a and second pipe branches 41b.

[0141] In the above structure, the correspondence between the different positions and different installation locations of the pipe branch 41 improves the installation stability of the pipe branch 41, facilitates the placement of the pipe branch 41, and effectively avoids the pipe branch 41 from getting tangled or knotted.

[0142] In practice, the first mounting position 31, the second mounting position and the third mounting position can also be selected for installing other parts of the pipeline branch 41, and this embodiment does not limit this.

[0143] In some embodiments, the fluid drive device 100 includes a plurality of flushing pumps 1, each flushing pump 1 including an infusion pump 1a and a circulation pump 1b. The infusion pump 1a is disposed in a first placement area 3a, and the circulation pump 1b is disposed in a second placement area 3b. A first pipeline branch 41a includes an infusion pipe, and a second pipeline branch 41b includes a circulation inlet pipe. The infusion pipe is connected to a storage device. The infusion pump 1a has a third mounting position 313a in the first placement area corresponding to the infusion pipe. The infusion pump 1a is used to pump fluid from the storage device into the interventional device through the flushing pipeline 4B. The circulation inlet pipe is connected to the flushing fluid inlet of the interventional device. The circulation pump 1b has a third mounting position 313b in the second placement area corresponding to the circulation inlet pipe. The circulation pump 1b is used to drive fluid to circulate between the interventional device and the flushing pipeline 4B. This provides a fluid drive system with two pumps, infusion pump 1a and circulation pump 1b, connected in series. By adjusting the pump speeds of infusion pump 1a and circulation pump 1b, the pump speed at which fluid is pumped into the interventional device can be adjusted. It also ensures the correspondence between the infusion tubing and infusion pump 1a, as well as the correspondence between the circulation tubing and circulation pump 1b, guaranteeing connections between these systems. This reduces the likelihood of connections between the infusion tubing and circulation pump 1a, and facilitates the installation of the flushing tubing 4B by the operator. Furthermore, the presence of a third mounting position on both infusion pump 1a and circulation pump 1b eliminates the need for additional pre-reserved space, effectively reducing the overall size of the fluid drive device and simplifying its structure.

[0144] In this embodiment of the present disclosure, in the fluid drive mode of dual pumps 1a and 1b connected in series, the plurality of pipeline branches 41 further include a third pipeline branch, which is placed in its corresponding placement area. The placement area corresponding to the third pipeline branch 41c can be on the pipeline fixing assembly 22 or other locations.

[0145] The third pipeline branch 41c may include a circulation outlet pipe 41c, and the infusion pipe, circulation inlet pipe, and circulation outlet pipe 41c are interconnected. The fluid drive device 100 also includes a fourth mounting position 4 corresponding to the circulation outlet pipe 41c. In this way, entanglement between the circulation outlet pipe 41c and the infusion pipe, as well as between the circulation outlet pipe 41c and the circulation inlet pipe, is avoided, further reducing the probability of entanglement between pipeline branches 41 in the flushing pipeline 4B.

[0146] To simplify the structure of the fluid drive device and facilitate the placement of the inlet pipe, the circulation inlet pipe, and the circulation outlet pipe 41c, the fourth mounting position 4, the first mounting position 311a of the first placement area corresponding to the inlet pipe, and the first mounting position 311b of the second placement area corresponding to the circulation inlet pipe can be located in the same mounting part, such as the pipeline fixing assembly 22.

[0147] As shown in Figures 4-7, in some embodiments, the fluid drive device 100 includes a drive housing 2, which includes a drive housing body 21 and a pipeline fixing assembly 22. The pipeline fixing assembly 22 is detachably mounted on the drive housing body 21 and is used to house the branch junction of the flushing pipeline 4B, which is the junction where multiple pipeline branches 41 intersect. For example, 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. The branch junction includes the junction of the first pipeline branch 41a, the second pipeline branch 41b, and the circulation outlet pipe 41c; a portion of the first pipeline branch 41a near the junction; a portion of the second pipeline branch 41b near the junction; and a portion of the circulation outlet pipe 41c near the junction.

[0148] As described above, the fluid drive device has a placement area 3, and a first mounting position of each or at least one placement area 3 is provided on the pipe fixing assembly 22. For example, a first mounting position 311a of the first placement area and a first mounting position 311b of the second placement area are provided on the pipe fixing assembly 22.

[0149] As mentioned above, the fluid drive device 100 also includes a fourth mounting position 4 corresponding to the circulation outlet pipe 41c. In this case, the fourth mounting position 4 is located on the pipe fixing assembly 22.

[0150] In the above embodiments, by placing the branch junction of the flushing pipe 4B on the pipe fixing assembly 22, the pipe fixing assembly 22 is detachably installed on the drive housing body 21. Thus, if the flushing pipe design changes, for example, if the connectors linking the various pipe branches change, only the mechanical design of the pipe fixing assembly 22 needs to be modified, without changing the entire drive housing 2. Similarly, if different flushing pipes are used, for example, if the connectors of the flushing pipes are different, the corresponding pipe fixing assembly 22 can be replaced without replacing the entire drive housing 2. Therefore, the above structure improves the adaptability of the fluid drive device 100 and reduces costs.

[0151] To facilitate the installation of the pipe fixing component 22, the drive housing body 21 can be provided with a groove 2103, in which the pipe fixing component 22 is detachably installed. In this way, the bottom wall of the groove 2103 supports the pipe fixing component 22, thereby facilitating its installation.

[0152] As shown in Figures 2, 4, and 8-10, in this embodiment of the present disclosure, the fluid drive device 100 includes a flushing pump 1 and a drive housing 2. The drive housing 2 includes a fixedly connected upper drive housing 2101 and a lower drive housing 2102. At least three mounting positions are provided on the upper drive housing 2101. The motor 11 of the flushing pump 1 is fixed to the inner side of the upper drive housing 2101. The control module 6 of the fluid drive device 100 is located on the inner side of the lower drive housing 2102. The control module 6 is connected to the motor 11 and used to control the motor 11. Thus, based on the structure of the drive housing 2, the motor 11 of the flushing pump 1 and the control module 6 are rationally arranged, improving the overall structural compactness of the fluid drive device 100 and facilitating the connection between 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 pipeline fixing assembly 22, the first of the at least three mounting positions 31 is disposed on the drive upper housing 2101 via the pipeline fixing assembly 22. Both the drive upper housing 2101 and the drive bottom housing 2102 can be understood as part of the drive housing body 21.

[0154] As shown in Figures 7 and 8, the drive housing 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. The first platform portion 21011, the inclined portion 21012, and the second platform portion 21013 are sequentially connected in the first axial direction. The motor 11 is mounted on the inclined portion 21012, which can be understood as the flushing pump 1 being mounted on the inclined portion 21012. In this way, the structure of the drive housing 2101 saves volume compared to the fully flat structure, making the drive housing 2 easier to adapt to the control console 200. Compared to the fully inclined structure, the first platform part 21011 and the second platform part 21013 of the drive housing 2101 are easier to install the flushing pipe 4B, making the installation of the flushing pipe 4B more stable. The flushing pump 1 is installed on the inclined part 21012, making it easier for the operator to operate the flushing pump 1 and also making it easier to install the flushing pipe 4B on the flushing pump 1. The bottom of the flushing pump 1 also needs to be equipped with a control module. The motor 11 is suspended and fixed on the inclined part 21012, which reserves space for the installation of the control module, improves the structural compactness of the entire device, and also facilitates the heat dissipation of the motor 11.

[0155] In the above structure, the infusion pump 1a has a lower rotational speed, while the circulation pump 1b has a higher rotational speed. By mounting the circulation pump 1b on the inclined part 21012, the flushing fluid is subjected to both the force of the circulation pump 1b and gravity, which increases the flow rate of the circulation pump 1b, facilitates the circulation of the flushing fluid, and also helps to meet the high rotational speed requirement of the circulation pump 1b.

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

[0157] As described above, the multiple placement areas 3 include a first placement area 3a and a second placement area 3b. The first placement area 3a includes a portion of a first platform portion 21011, a portion of a second platform portion 21013, and a portion of an inclined portion 21012, with the pipe fixing assembly 22 disposed on the first platform portion 21011. Specifically, the first mounting position 311a of the first placement area is located on the first platform portion 21011, the second mounting position 312a of the first placement area is located on the second platform portion 21013, and the third mounting 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 mounting position 311b of the second placement area is located on the first platform portion 21011, the second mounting position 312b of the second placement area is located on the second platform portion 21013, and the third mounting position 313b of the second placement area is located on the inclined portion 21012. In this configuration, the pipe routing corresponding to the first mounting position 311a in the first placement area is along the second axial direction, and the pipe routing corresponding to the second mounting position 312a in the first placement area is also along the second axial direction. This allows the first pipe branch 41a to fit more closely to the surfaces of the first platform portion 21011 and the second platform portion 21013, improving the installation stability of the first pipe branch 41a. Simultaneously, the first pipe branch 41a will not bend at either the first mounting position 311a or the second mounting position 312a in the first placement area, shortening the length of the bent portion of the first pipe branch 41a and reducing the size of the first pipe... The fluid flow resistance within branch 41a; simultaneously, after the first pipe branch 41a extends out of the first mounting position 311a of the first placement area along the second axis, it is convenient to bend to one side of the first axis and enter the third mounting position 313a of the first placement area, which can increase the bending angle of the pipe branch 41 between the first mounting position 311a and the third mounting position 313a of the first placement area. Correspondingly, it can also increase the bending angle of the pipe branch 41 between the third mounting position 313a and the second mounting position 312a of the first placement area, thereby facilitating the operator to install the first pipe branch 41a.

[0158] Correspondingly, the pipe routing corresponding to the first mounting position 311b in the second placement area is along the second axis, and the pipe routing corresponding to the second mounting position 312b in the second placement area is also along the second axis. This improves the installation stability of the second pipe branch 41b, shortens the length of the bent portion of the second pipe branch 41b, reduces the fluid flow resistance in the second pipe branch 41b, and also makes it easier for operators to install the second pipe branch 41b.

[0159] As mentioned above, the multiple pipeline branches 41 also include a third pipeline branch, the placement area of ​​which includes a portion of the first platform section 21011.

[0160] As shown in Figures 8 and 9, the fluid drive device 100 also includes a motor support assembly 5, through which the motor 11 is fixed to the inclined portion 21012. 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 fixation of the motor 11.

[0161] The specific structure of the motor support assembly 5 is selected according to the actual situation. In some embodiments, the motor support assembly 5 includes: a support ramp 51, a support top plate 52 fixedly connected to the top end of the support ramp 51, and a support bottom plate 53 fixedly connected to the bottom end of the support ramp 51; wherein, the support ramp 51 is provided with a through hole 5101 through which the motor 11 passes, the motor 11 is fixed to the support ramp 51, the support top plate 52 is fixed to the first platform portion 21011 or the inclined portion 21012, and the support bottom plate 53 is fixed to the second platform portion 21013 or the inclined portion 21012. In this way, the structure of the motor support assembly 5 is adapted to the structure of the drive upper housing 2101, which facilitates the fixed connection between the motor support assembly 5 and the drive upper housing 2101; moreover, at least two of the inclined portion 21012, the first platform portion 21011 and the second platform portion 21013 of the drive upper housing 2101 can be 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 housing 2101.

[0162] As mentioned above, the fluid drive device has multiple flushing pumps 1. As shown in Figures 2, 7, and 10, at least two flushing pumps 1 can be selected and distributed sequentially along the second axis. The control module 6 is equipped with a radiator 62, which is located between the motors 11 of two adjacent flushing pumps 1 along the second axis. In this way, the space between the motors 11 of two adjacent flushing pumps 1 along the second axis is fully utilized, improving the structural compactness of the fluid drive device and helping to reduce the size of the fluid drive device.

[0163] As described above, the fluid drive device 100 is placed on the console 200. Referring to Figures 2, 6, 10-12, and 22, in some embodiments, the console 200 includes a tilted back panel 201 and a base 202, forming a placement space between the tilted back panel 201 and the base 202 to accommodate the fluid drive device 100. The fluid drive device 100 includes a tilted 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 both the bottom wall 2105 and the inclined rear wall 2106 are walls of the drive base 2102.

[0165] The bottom wall 2105 has a cable fixing structure 9 on one side along the first axial direction, and the cable fixing structure 9 has a cable through hole 924. A control module 6 is provided on the other side of the bottom wall 2105 along the first axial direction. Along the first axial direction, the mounting width d of the combined assembly of the cable fixing structure 9 and the control module 6 is greater than the mounting width e of the base 202. The bottom wall 2105 includes a horizontal portion and a raised portion, and the mounting width e of the base 202 and the width f of the horizontal portion of the bottom wall 2105 are equal. Thus, without changing the mounting width e of the base 202 and the width f of the horizontal portion of the bottom wall 2105, the structural compactness of the fluid drive device 100 is improved, which is beneficial for reducing the volume of the fluid drive 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 connect 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. To minimize the installation width d of the combined assembly of the cable fixing structure 9 and the control module 6, the installation areas of the cable fixing structure 9 and the control module 6 can overlap in the first axial direction. To achieve partial overlap between the installation areas of the cable fixing structure 9 and the control module 6 in the first axial direction, the control module 6 is provided with a first recess 61, forming a clearance area in which a portion of the cable fixing structure 9 is located. This achieves partial overlap between the installation areas of the cable fixing structure 9 and the control module 6 in the first axial direction, reducing the installation width d of the combined assembly of the cable fixing structure 9 and the control module 6, thus facilitating the installation of the control module 6 and the cable fixing structure 9.

[0168] Because the control module 6 has a first recess 61, its width in the first axial direction is reduced. To ensure sufficient space for circuit design on the control module 6, it can also have a first protrusion 63. This ensures that the width of the control module 6 in the first axial direction remains constant or changes only slightly. To accommodate the first protrusion 63, the inclined rear wall 2106 has a second protrusion 21061, which protrudes outward from the inclined rear wall 2106 and serves to accommodate the first protrusion 63. Thus, the inclined rear wall 2106 provides space to accommodate the control module 6, effectively improving the structural compactness of the fluid drive device 100 and reducing its volume.

[0169] In practice, other methods can be chosen to achieve this: 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 does not limit this.

[0170] In the fluid drive device 100, the control module 6 and the control console 200 are connected via a drive cable 8. Shaking of the drive cable 8 can cause unstable signal transmission, affecting the performance of the fluid drive device 100. Therefore, to improve the stability of signal transmission, there is a need to securely fix the drive cable 8, and the more securely it is fixed, the better.

[0171] As shown in Figures 10-16, the fluid drive device 100 also includes a cable bracket 7, which is placed on the cable fixing structure 9. The cable bracket 7 is used to fix the drive cable 8 between the control module 6 and the control console 200. In this way, fixing the drive cable 8 with the cable bracket 7 improves the rigidity of the drive cable 8, reduces the degree of shaking of the drive cable 8, thereby improving the stability of signal transmission and the reliability of the connection between the control module 6 and the control console 200; it also facilitates the extension of the drive cable 8 from the control module 6 to the control console 200, thus making the routing of the drive cable 8 easier.

[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 inward to the bottom wall 2105, the first protrusion 91 being 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, 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 ​​vertically to fix the drive cable 8 between the control module 6 and the console 200.

[0173] The aforementioned first protrusion 91 and second protrusion 92 protrude inward from the bottom wall 2105 itself. Inside the bottom wall 2105, i.e., inside the drive housing 2, the surface of the first protrusion 91 includes a first protrusion top wall 911 and a first protrusion side wall 912, and the surface of the second protrusion 92 includes a second protrusion top wall 921 and a second protrusion side wall 922. The second bracket 72 can be fixed to the surface of the second protrusion 92, for example, the second protrusion top wall 921 and / or the second protrusion side wall 922. The first bracket 71 can be fixed to the first protrusion top wall 911 and the second protrusion side wall 922, or it can be fixed to the first protrusion top wall 911 and the second protrusion top wall 921, etc. As mentioned above, the cable fixing structure 9 is provided with a wire through hole 924, which can be provided on the second protrusion top wall 921 of the second protrusion 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 ​​together 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 cable hole 924 before the first bracket 71 is installed. In this way, compared to the drive cable 8 passing directly through the round hole, the routing of the drive cable 8 is more convenient, thus facilitating the fixing of the drive cable 8. The end of the drive cable 8 has a connector, which is usually larger than the diameter of the drive cable 8. If the drive cable 8 passes directly through the round hole, the round hole will be larger due to the connector, resulting in a poor limiting effect on the drive cable 8. However, in this case, the first bracket 71 and the second bracket 72 are spliced ​​vertically to fix the drive cable, which is not affected by the connector. 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 is installed. The first bracket 71 and the second bracket 72 are spliced ​​vertically, which facilitates the connection between the first bracket 71 and the second bracket 72, thus facilitating the fixing of the drive cable 8.

[0175] To facilitate the fixing of the drive cable 8 by the cable bracket 7, the first bracket 71 can be provided with a first semi-circular hole 7105 on the side away from the control module 6 along the first axis, and the second bracket 72 can be provided with a second semi-circular hole 7201 on the side away from the control module 6 along the first axis. The first semi-circular hole 7105 and the second semi-circular hole 7201 are spliced ​​together to form a first through hole for the drive cable 8 to pass through. Thus, the cable bracket 7 has a first through hole on the side away from the control module 6. The first through hole limits the drive cable 8, making it easy for the drive cable 8 to pass through the through hole 924. At the same time, the first semicircular hole 7105 and the second semicircular hole 7201 are spliced ​​together to form the first through hole. During installation, 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, 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 fixation of the drive cable 8. Moreover, the first semicircular hole 7105 and the second semicircular hole 7201 are spliced ​​together to form the first through hole. This structure also has the technical effect brought about by splicing mentioned above, which will not be repeated here.

[0176] To facilitate the fixing of the drive cable 8 by the cable bracket 7, the first bracket 71 can be provided with an arched mounting portion 7101 on the side of the first bracket 71 near the control module 6 along the first axis, and the first protrusion 91 can be provided with a cable support portion 913. For example, the cable support portion 913 is provided on the top wall 911 of the first protrusion. When the first bracket 71 and the first protrusion 91 are fixedly connected vertically, the arched mounting portion 7101 and the cable support portion 913 are spliced ​​together 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 near the control module 6. The second through hole limits the drive cable 8, thereby reducing the degree of shaking of the part of the drive cable 8 connected to the control module 6 and effectively improving the connection stability between the drive cable 8 and the control module 6. Moreover, the arched mounting portion 7101 and the cable support portion 913 splicing together to form a second through hole also have the technical effects brought about by splicing mentioned above, which will not be repeated here.

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

[0178] In practice, both the first and second through holes can be selected. This improves the fixation of the drive cable 8 and facilitates control over its routing. With both holes present, the second through hole is located between the first through hole and the control module 6, and the first through hole is lower than the second. This design constrains the two positions of the drive cable 8, facilitating control over its routing and simplifying installation.

[0179] The following describes the specific structure of the cable bracket 7 and the connection structure between the cable bracket 7 and the cable fixing structure 9.

[0180] In this embodiment, 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; a first semi-circular hole 7105 is disposed on the inclined beam 7104, and both the arched mounting portion 7101 and the flat mounting portion 7102 are mounted on the second protrusion 92; the second bracket 72 is located on the bottom side of the crossbeam 7103. This facilitates the formation of a first through hole between the first bracket 71 and the second bracket 72, and also facilitates the placement of the first bracket 71 on the first protrusion 91 and the second protrusion 92.

[0181] To facilitate the installation of the first bracket 71, the top wall 911 of the first protrusion 91 is provided with a first fixing post 914, and the two ends of the arched mounting portion 7101 are provided with mounting posts 7108. The mounting posts 7108 and the first fixing posts 914 correspond one-to-one and are fixedly connected by fasteners. It should be noted that both the mounting posts 7108 and the first fixing posts 914 are hollow structures, that is, both the mounting posts 7108 and the first fixing posts 914 are provided with fixing holes. For ease of installation, one of the mounting posts 7108 and the first fixing posts 914 is fitted over the other. In this way, the mounting posts 7108 and the first fixing posts 914 can also guide each other, thereby facilitating the installation of the first bracket 71. Of course, the mounting posts 7108 and the first fixing posts 914 can be connected together, and this embodiment of the present disclosure does not limit this.

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

[0183] The second protrusion 92 has a second fixing post 923 on its second protrusion sidewall 922, and the flat plate mounting part 7102 and the second fixing post 923 are fixedly connected by fasteners.

[0184] As mentioned above, the second protrusion 92 is provided with a wire hole 924. In order to facilitate wire routing, the wire hole 924 can be located between the second fixing post 923 and the first fixing post 914.

[0185] In the first bracket 71, two parallel first limiting plates 7106 are provided at the connection between the crossbeam 7103 and the inclined beam 7104, which are used to limit the drive cable 8; two parallel second limiting plates 7107 are provided at the connection between the crossbeam 7103 and the arched mounting part 7101, which are used to limit the drive cable 8. In this way, part of the drive cable 8 is located between the two second limiting plates 7107 and part of the drive cable 8 is located between the two first limiting plates 7106. The first limiting plates 7106 and the second limiting plates 7107 constrain the direction of the drive cable 8, making it easier for the drive cable 8 to pass through the first through hole.

[0186] The first support 71 can be a single component, meaning that all components in the first support 71 are integral structures; or, at least two components in the first support 71 are separate structures, and this disclosure does not limit this.

[0187] In practice, the first support 71 can also be other structures, and is not limited to the above embodiments.

[0188] In this embodiment of the present disclosure, the second bracket 72 includes: a third limiting plate 7202, a connecting horizontal plate 7203, a mounting plate 7204, a fourth limiting plate 7205, and a second snap-fit ​​plate 7206.

[0189] The third limiting plate 7202 and the first bracket 71 are connected in a limiting manner. The bottom side of the crossbeam 7103 of the first bracket 71 is provided with limiting ribs 7109, which engage with the third limiting plate 7202. For example, there may be one limiting rib 7109 and two third limiting plates 7202, with the two third limiting plates 7202 engaging with the two sides of the limiting rib 7109; or, there may be two limiting ribs 7109 and two third limiting plates 7202, with the two third limiting plates 7202 limiting the two sides of the two limiting ribs 7109, or the two third limiting plates 7202 limiting the two limiting ribs 7109. The number of limiting ribs 7109 and third limiting plates 7202 can be adjusted, but this embodiment does not limit this.

[0190] Because the limiting rib 7109 and the third limiting plate 7202 cooperate to limit each other, the second support 72 can be prevented from sliding relative to the first support 71, thereby improving the stability of the second support 72.

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

[0192] To facilitate the connection between the second bracket 72 and the cable fixing structure 9, the second snap-fit ​​plate 7206 and the second protrusion 92 snap-fit ​​together. Specifically, there are at least two second snap-fit ​​plates 7206 distributed on both sides of the mounting plate 7204. The second snap-fit ​​plates 7206 snap-fit ​​onto the second protrusion sidewall 922 of the second protrusion 92. In this way, the second protrusion 92 does not need to have a separate snap-fit ​​structure, which simplifies the structure of the second protrusion 92.

[0193] To improve the stability of the second bracket 72, the side of the fourth limiting plate 7205, the connecting horizontal plate 7203, and the third limiting plate 7202 that is away from the mounting plate 7204 all abut against the first protrusion sidewall 912 of the first protrusion 91, and the other side of the fourth limiting plate 7205 abuts against the top wall 921 of the second protrusion. 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 also improves the stability of the second bracket 72.

[0194] As mentioned above, the second bracket 72 is provided with a second semi-circular hole 7201, which can be disposed on the mounting plate 7204. Two second snap-fit ​​plates 7206 are distributed on both sides of the second semi-circular hole 7201.

[0195] In the second bracket 72 mentioned above, the two third limiting plates 7202 can also limit the drive cable 8. In this way, the third limiting plates 7202 constrain the direction of the drive cable 8, making it easier for the drive cable 8 to pass through the first through hole.

[0196] In this embodiment, during installation, the second bracket 72 is first placed directly on the second protrusion 92, so that the second snap-fit ​​plate 7206 of the second bracket 72 and the side wall 922 of the second protrusion are snapped together, 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 passes through the cable support part 913 and the second semi-circular hole 7201 and through the wire hole 924 in sequence; 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 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, and the first bracket 71 and the cable fixing structure 9 clamp and fix 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 practice, the second support 72 can 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 mounted at the inclined portion 21012. When using the housing of another device as the drive housing 2, the width g of the drive housing 2 at its inclined portion 21012 is limited, and the thickness direction of the drive housing 2 at its inclined portion 21012 is the first axial direction. To ensure that the flushing pump 1 is installed within the limited space, the size of the flushing pump 1 needs to be minimized as much as possible, especially the size (motor height) of the motor 11 of the flushing pump 1. Furthermore, the control module 6 needs to be placed on the bottom side of the motor 11 of the flushing pump 1; to avoid interference between the motor 11 and the control module 6, the size (motor height) of the motor 11 also needs to be reduced.

[0199] In some embodiments, as shown in Figures 17-20, the flushing pump 1 further includes: a motor base cover 12, a grating gear disk 1301, and a grating sensor 1302. It should be noted that both the grating gear disk 1301 and the grating sensor 1302 can be understood as part of the speed sensor 13. In practice, the speed sensor 13 can also be of other types, and this disclosure does not limit its 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 gear disk 1301. To facilitate the connection between the rotating shaft and the grating gear disk 1301, the grating gear disk 1301 can be connected to the rotating shaft via a bearing 15 to ensure that the rotating shaft and the grating gear disk 1301 rotate synchronously.

[0201] The grating sensor 1302 includes a first end 13021 and a second end 13022, with a gap between the first end 13021 and the second end 13022 to accommodate the grating gear disk 1301. The motor bottom cover 12 is connected to the motor bottom wall 1101 and has a notch. The grating sensor 1302 is inserted into the notch to form a sealed space to cover the grating gear disk 1301. In this way, the grating sensor 1302 is externally mounted, and the motor bottom cover 12 and the grating sensor 1302 together form a sealed space. The motor bottom cover 12 does not need to completely surround the speed sensor 13 (the part of the motor bottom cover 12 that surrounds the grating sensor 1302), thus reducing the size of the motor bottom cover 12 and effectively reducing the volume of the entire flushing pump 1.

[0202] Furthermore, the distance between the bottom end of the motor base cover 12 and the bottom wall 1101 of the motor is less than or equal to the distance between the bottom end of the grating sensor 1302 and the bottom wall 1101 of the motor. This reduces the axial dimension of the motor base cover 12 on the motor 11, thereby reducing the volume of the flushing pump 1. Simultaneously, the bottom end and bottom side of the motor base cover 12 can accommodate other components, such as the components of the control module 6, improving the structural compactness of the fluid drive device 100.

[0203] In some embodiments, the grating sensor 1302 further includes a sensor fixing part 13023, and the motor bottom cover 12 includes a sensor mounting part. When the grating sensor 1302 is inserted into the notch, the sensor fixing part 13023 and the sensor mounting part are fixedly connected, and the sensor fixing part 13023 is located on the side of the sensor mounting part away from the motor bottom wall 1101. This facilitates the fixed connection of the grating sensor 1302 and the motor bottom cover 12, facilitates the assembly of the grating sensor 1302, and also ensures 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 base cover 12 are selected according to the actual situation. In some embodiments, the motor base cover 12 includes: a first base cover plate 1201, a second base cover plate 1202, and a base cover side plate 1203; wherein, the first base cover plate 1201 is located around the second base cover plate 1202, and the second base cover plate 1202 is farther away from the motor 11 than the first base cover plate 1201, and the base cover side plate 1203 connects the first base cover plate 1201 and the second base cover plate 1202; the first base cover plate 1201 is fixedly connected to the motor 11, and the grating sensor 1302 is fixedly connected to the second base cover plate 1202.

[0205] Of course, the motor base cover 12 can also be selected with other structures, and this embodiment does not limit this.

[0206] As shown in Figure 21, the fluid drive device 100 includes two flushing pumps 1, which are symmetrically arranged. When each flushing pump 1 includes a speed sensor 13, it also includes a connector 14. 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, which is also used to connect to the control module 6. For ease of wiring, the speed sensors 13 of the two flushing pumps 1 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 speed sensor 13 share one connector 14. This allows the control module 6 to control both the motor 11 and the speed sensor 13 using only one wiring harness, simplifying the structure and wiring. Alternatively, each flushing pump 1 can have two connectors 14, with the motor 11 and speed sensor 13 each connected to the control module 6 using a separate connector 14.

[0208] In the fluid drive device 100, the drive housing 2 is provided with at least one direction indicator to indicate the direction of fluid delivery within at least one pipeline branch 41. This facilitates the installation of the flushing pipeline 4B and the flushing pump 1.

[0209] The specific type and number of directional markers, for example, arrow markers, are selected according to the actual situation, and this disclosure does not limit this.

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

[0211] As shown in Figure 22, in some embodiments, the console 200 is provided with a second recess 203. As described above, the console 200 includes an inclined back plate 201 and a base 202, with the second recess 203 located on the inclined back plate 201. The console 200 has a first state for use in an external magnetically levitated artificial heart and a second state for use in an interventional artificial heart; in the first state, the second recess 203 is used to accommodate a magnetically levitated motor; in the second state, the second recess 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. This allows the first recess 61 of the control module 6 to make way for the cable fixing structure 9, thereby fixing the control module 6 and the cable fixing structure 9 simultaneously on the bearing plane formed by the base 202. This achieves partial overlap of the installation areas of the cable fixing structure 9 and the control module 6 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, making it easier to install the control module 6 and the cable fixing structure 9.

[0213] Because the control module 6 has a first recess 61, its width in the first axial direction is reduced. To ensure sufficient space for circuit design, the control module 6 can also have a first protrusion 63. This ensures that the width of the control module 6 in the first axial direction remains constant or changes only slightly. To accommodate the first protrusion 63, the inclined rear wall 2106 has a second protrusion 21061, which protrudes outward from the inclined rear wall 2106 and serves to accommodate the first protrusion 63. Thus, the inclined rear wall 2106 provides space to accommodate the control module 6, effectively improving the structural compactness of the fluid drive device 100 and reducing its volume, without requiring modification to the device structure of the control console 200.

[0214] In this way, the console 200 can be adapted to both the magnetic levitation motor and the fluid drive device 100, improving the adaptability of the console 200. At the same time, the external magnetic levitation artificial heart and the interventional artificial heart can use the same console 200 (i.e., the aforementioned console 200), reducing the types of consoles 200 and lowering the research and development costs.

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

[0216] The above description of the disclosed embodiments enables those skilled in the art to make or use this disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
