Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a driving pump testing device and a testing method thereof. Background Art

[0002] Extracorporeal Membrane Oxygenation (ECMO) is mainly used to provide continuous extracorporeal respiration and circulation for patients with severe cardiopulmonary failure to maintain the lives of patients. The hand-cranked driving pump in the extracorporeal membrane oxygenation system is one of its components. The function of the hand-cranked driving pump is that when the electric medical pump or the main unit fails, the operator can pump blood for the patient by hand-cranking instead of the electric medical pump. Therefore, the hand-cranked driving pump is the last line of defense in case of emergency in the extracorporeal membrane oxygenation system. It is crucial to ensure the accuracy and reliability of the performance of the hand-cranked driving pump. However, the hand-cranked driving pump is not powered on and is driven by manpower. To ensure convenient and labor-saving operation, the hand-cranked driving pump is not suitable for carrying various precision detection and control modules. Therefore, challenges are posed to factors such as the state of the hand-cranked driving pump during actual and long-term operation, its reliability, and whether the displayed speed range is accurate.

[0045] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0046] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0047] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0048] In the present application, unless otherwise clearly specified and limited, if there are terms such as "mounted", "connected", "joined", "fixed", etc., these terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0049] In the present application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0050] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0051] Referring to Figure 1 As shown, an embodiment of the present application provides a driving pump test device, which includes a tooling base 1000, a positioning device 2000, a power device 3000 and a load assembly 4000. The positioning device 2000 is disposed on the tooling base 1000, and the positioning device 2000 is used to fix the driving pump 100 to be tested so that the driving pump 100 can be in a stable state to be detected. The positioning device 2000 can be implemented in various ways such as clamping and snap connection to fix the driving pump 100, as long as the driving pump 100 meets the requirements of height, angle and stability during the detection process. Continuing to refer to Figure 1 As shown, the positioning device 2000 may include a positioning mounting seat 2100 and a positioning clamping arm 2200. The positioning mounting seat 2100 is disposed on the tooling base 1000, and the driving pump 100 can be first assembled on the positioning mounting seat 2100 to determine the position of the driving pump 100.

[0052] Among them, the driving pump to be tested can be an electric driving pump or a hand-cranked driving pump. According to the different driving sources of the driving pump, it can be selected whether to use the power device 3000 to provide power support according to the needs. For example, when the driving pump to be tested is an electric driving pump, the electric driving pump can be powered on and rotated by itself, so there is no need for the power device 3000 to provide power support. At this time, only the electric driving pump needs to be fixed on the positioning device 2000, and a suitable load is applied to the output end of the electric driving pump in cooperation with the load assembly 4000. When the driving pump to be tested is a hand-cranked driving pump, the input end of the hand-cranked driving pump needs to be connected to the power device 3000 to obtain power support, the hand-cranked driving pump is fixed on the positioning device 2000, and a suitable load is applied to the output end of the hand-cranked driving pump in cooperation with the load assembly 4000.

[0053] Therefore, the positioning device 2000, the power device 3000 and the load assembly 4000 of the driving pump test device can form a modular usage form, and the positioning device 2000, the power device 3000 and the load assembly 4000 are selected according to the actual test object and test scenario to obtain corresponding function support. This modular design idea can achieve all-round scenario simulation of the driving pump and reliable detection conclusions through low-cost design.

[0054] To facilitate the installation of the drive pump 100, a first positioning area 2100a may also be provided on the positioning mounting base 2100, and the drive pump 100 is installed by using the first positioning area 2100a. The first positioning area 2100a may be constructed according to the shape characteristics of the drive pump 100. For example, the first positioning area 2100a is constructed as a groove or depression and other structures that are mutually adapted to the shape characteristics of the drive pump 100, or may be a protrusion and other structures that are mutually adapted to the corresponding depression area on the drive pump 100. Those skilled in the art can set the size, shape, etc. of the first positioning area 2100a according to actual needs, and no limitation is made here.

[0055] The positioning clamping arm 2200 is a structure used for clamping cooperation with the positioning mounting base 2100. The positioning clamping arm 2200 can adopt robotic arms in various adapted forms and can be movably arranged on the tooling base 1000 through structures such as a robotic base, so that the positioning clamping arm 2200 can move relative to the positioning mounting base 2100. When the positioning clamping arm 2200 moves away from the positioning mounting base 2100, the first positioning area 2100a on the positioning mounting base 2100 can be vacated, and the drive pump 100 can be installed in the first positioning area 2100a of the positioning mounting base 2100. Then when the positioning clamping arm 2200 moves closer to the positioning mounting base 2100, the positioning clamping arm 2200 can gradually approach the drive pump 100 and finally come into contact with each other, clamping and positioning the drive pump 100 between the positioning mounting base 2100 and the positioning clamping arm 2200.

[0056] Similar to the first positioning area 2100a on the positioning mounting base 2100, to facilitate the installation of the drive pump 100, a similar second positioning area 2200a may also be provided on the positioning clamping arm 2200, and the drive pump 100 is installed by using the second positioning area 2200a. The second positioning area 2200a may be constructed according to the shape characteristics of the drive pump 100. For example, the second positioning area 2200a is constructed as a groove or depression and other structures that are mutually adapted to the shape characteristics of the drive pump 100, or may be a protrusion and other structures that are mutually adapted to the corresponding depression area on the drive pump 100. Those skilled in the art can set the size, shape, etc. of the second positioning area 2200a according to actual needs, and no limitation is made here.

[0057] Continue to refer to Figure 1As shown, the power device 3000 is arranged on the tooling base 1000. The output end of the power device 3000 is used to connect to the drive pump 100, and its function is to apply a power source to the drive pump 100. A rotation detection device 3100 can be assembled at the output end of the power device 3000. According to different sources of the drive pump, the output end of the power device 3000 can selectively use the rotation detection device 3100 to detect data such as torque and rotational speed. For example, when the drive pump 100 is an electric drive pump or a hand-operated drive pump, it can be selected whether to use the rotation detection device 3100 to connect to the input end of the drive pump 100. For example, when the drive pump 100 is a hand-operated drive pump, it can be selected to use the rotation detection device 3100 to connect to the input end of the drive pump 100. When the drive pump 100 is an electric drive pump, it is not necessary to use the rotation detection device 3100 to connect to the input end of the drive pump 100.

[0058] The output end of the power device 3000 can be connected to the input end of the drive pump 100 through the rotation detection device 3100. When the power device 3000 provides a power source to drive the drive pump 100 to rotate, the rotation detection device 3100 is located between the output end of the power device 3000 and the input end of the drive pump 100, and can detect data such as the torque and rotational speed of the drive pump 100. For example, the rotation detection device 3100 can adopt a torque and rotational speed sensor to simultaneously detect the torque and rotational speed of the drive pump 100. Moreover, a transmission shaft 3200 can be assembled at the output end of the rotation detection device 3100, so that the output end of the rotation detection device 3100 and the input end of the drive pump 100 are connected through the transmission shaft 3200. Since the actual drive pump 100 has a handle, the transmission shaft 3200 can also be replaced with other suitable transmission adapters that can be connected to the handle, so that the reliability of the handle can also be tested simultaneously.

[0059] The load component 4000 can also be arranged on the tooling base 1000. The purpose of the load component 4000 is to provide the required load to the drive pump 100, simulate the operation of the drive pump 100, and then detect the operating performance of the drive pump 100. The load component 4000 can be connected to the output end of the drive pump 100 to apply load forces in different directions such as a circumferential rotational torque and an axial force to the drive pump 100. The application of various load forces can be carried out by one device, or by two or more devices in cooperation. Those skilled in the art can set the application methods of various load forces according to actual needs. For example, in one embodiment, the load component 4000 can include a first load device 4100 and a second load device 4200. The first load device 4100 is used to connect to the output end of the drive pump 100, and the first load device 4100 is responsible for applying a rotational load torque to the output end of the drive pump 100. The second load device 4200 is used to connect to the output end of the drive pump 100, and the second load device 4200 is responsible for applying an axial load force to the output end of the drive pump 100.

[0060] The first load device 4100 and the second load device 4200 can both be directly connected to the output end of the driving pump 100. Or in one embodiment, the first load device 4100 can be used to be directly connected to the output end of the driving pump 100, the second load device 4200 is connected to the first load device 4100, and then is connected to the output end of the driving pump 100 through the first load device 4100. Similarly, the second load device 4200 can be used to be directly connected to the output end of the driving pump 100, the first load device 4100 is connected to the second load device 4200, and then is connected to the output end of the driving pump 100 through the second load device 4200. Those skilled in the art can select the connection mode between the first load device 4100 and the second load device 4200 and the output end of the driving pump 100 according to actual needs, which is not limited herein.

[0061] The first load device 4100 applies a rotational load torque to the output end of the driving pump 100, and a torque control device such as a hysteresis brake can be used. The second load device 4200 applies an axial load force to the output end of the driving pump 100, and the elastic force applied axially can be used as the axial load force. For example, referring to Figure 2 As shown, the second load device 4200 can include a guiding track 4200a and a guiding member 4200b. The guiding track 4200a is arranged on the tooling base 1000, the guiding member 4200b is movably assembled on the guiding track 4200a along the guiding track of the guiding track 4200a, and the guiding member 4200b can be locked at any position of the guiding track 4200a. The first load device 4100 is used to be connected to the output end of the driving pump 100, and the guiding member 4200b is elastically connected to the first load device 4100 through an elastic member 4200c. When the guiding member 4200b moves along the guiding track 4200a, the guiding member 4200b will pull or compress the elastic member 4200c. The elastic member 4200c generates a corresponding elastic force due to being pulled or compressed, and this elastic force will be applied to the output end of the driving pump 100. This elastic force is the axial load force applied to the output end of the driving pump 100.

[0062] As the guiding component 4200b moves along the guiding track 4200a, the tensile or compressive force on the elastic component 4200c changes, causing the axial load force exerted by the elastic component 4200c on the output end of the driving pump 100 to change accordingly. After the magnitude of the axial load force applied by the elastic component 4200c is adjusted, the guiding component 4200b can be locked at the current position on the guiding track 4200a, so that the axial load force applied by the elastic component 4200c can be determined. Among them, the guiding component 4200b can be locked on the guiding track 4200a in various ways such as clamping, threaded connection, bonding, and clamping. Those skilled in the art can select appropriate locking and unlocking methods according to actual needs, which are not limited herein.

[0063] In addition, the second load device 4200 may further include a connecting component 4200d. The connecting component 4200d is also movably assembled on the guiding track 4200a along the guiding trajectory of the guiding track 4200a, and the connecting component 4200d can be locked at any position on the guiding track 4200a. Similar to the locking method of the guiding component 4200b, the connecting component 4200d can also be locked on the guiding track 4200a in various ways such as clamping, threaded connection, bonding, and clamping. Those skilled in the art can select appropriate locking and unlocking methods according to actual needs, which are not limited herein. Therefore, referring to Figure 2 As shown, the connecting component 4200d can be used to connect to the first load device 4100, so that one end of the guiding component 4200b moves along the guiding track 4200a, the other end can be connected to the elastic component 4200c, and the elastic component 4200c is further connected to the first load device 4100 through the connecting component 4200d.

[0064] A flexible coupling 3300 can be provided at the input end of the load assembly 4000, so that the load assembly 4000 and the output end of the driving pump 100 are connected through the flexible coupling 3300. The function of the flexible coupling 3300 is to provide tolerance capacity when the load assembly 4000 and the output end of the driving pump 100 cannot be coaxial. Moreover, position marks can be set on the flexible coupling 3300. Referring to Figure 3 As shown, a marking sensor 5000 is provided on the tooling base 1000, and the marking sensor 5000 is used to identify the position marks during the rotation of the flexible coupling 3300. Among them, the position marks can be various marks recognizable by the marking sensor 5000. For example, when the marking sensor 5000 is a color sensor, the position marks can be drawn on the flexible coupling 3300 with a red oil pen, and the color sensor will identify this mark.

[0065] In addition to using the first load device 4100 and the second load device 4200, the load component 4000 can also adopt a fluid circulation device. The fluid circulation device can be a fluid circulation system that can continuously provide flowing fluid according to requirements. The fluid circulation device can apply the circulating fluid to the output end of the driving pump 100. The fluid applied to the output end of the driving pump 100 can form a load form in a flowing state, simulating the working scenario of the driving pump 100 and verifying the performance of the driving pump 100.

[0066] When the power device 3000 starts and drives the driving pump 100 to rotate, when the driving pump 100 outputs a rotational speed, the rotational speed display panel of the driving pump 100 will light up the rotational speed indicator lights of the corresponding gears to display the real-time rotational speed of the driving pump 100. At this time, the flexible coupling 3300 also rotates synchronously accordingly. If a position mark is set on the flexible coupling 3300, the position mark on the flexible coupling 3300 is identified by the mark sensor 5000. As the flexible coupling 3300 rotates, the mark sensor 5000 will identify the number of times the position mark passes within a unit time, and then identify and generate a pulse signal to detect the actual output rotational speed of the driving pump 100, which is used to compare with the rotational speed display panel of the driving pump 100 to determine whether the rotational speed displayed by the driving pump 100 is accurate.

[0067] In one embodiment, the driving pump testing device includes a lifting device 6000. The lifting device 6000 is arranged on the tooling base 1000, and at least one of the power device 3000 and the load component 4000 is arranged on the lifting device 6000. The lifting device 6000 is used to adjust the height of at least one of the power device 3000 and the load component 4000 on the tooling base 1000 to adapt to driving pumps 100 of different sizes to form a coaxial arrangement with the power device 3000, the load component 4000, etc. The lifting device 6000 can include a first lifting platform 6100 and a second lifting platform 6200. The first lifting platform 6100 is arranged on the tooling base 1000, and the power device 3000 is arranged on the first lifting platform 6100. The first lifting platform 6100 is used to adjust the height of the power device 3000 on the tooling base 1000. The second lifting platform 6200 is arranged on the tooling base 1000, and the load component 4000 is arranged on the second lifting platform 6200. The second lifting platform 6200 is used to adjust the height of the load component 4000 on the tooling base 1000.

[0068] The driving pump testing device provided by the present application can simulate the actual load environment of the driving pump 100, and then test the performance and reliability of the driving pump 100 in the simulated actual load environment. When testing, reference can be made to Figure 1Fix the driving pump 100 on the positioning device 2000. Connect the output end of the power device 3000 to the input end of the driving pump 100 through a rotation detection device 3100 or the like to form a power connection and provide a power source for the driving pump 100. Connect the output end of the driving pump 100 to the load assembly 4000 to provide the load force required for the test of the driving pump 100. After starting the power device 3000, the output end of the driving pump 100 will drive the load assembly 4000 to rotate.
