Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a location detection device and a ventricular assist device. Background Art

[0002] During the operation self-test of the transvalvular ventricular assist system controller (hereinafter referred to as the "controller or host"), consumables need to be installed in the perfusion chamber part (the consumables usually include a perfusion box and a pressure disc, and the assembly process is to install the perfusion box first, and then install the pressure disc). The controller can only start to execute subsequent programs after it recognizes that all the consumables are assembled. In addition, during the operation of the controller, there is a situation where the equipment is paused to replace a whole set of consumables: when the new consumables are installed, the perfusion chamber needs to recognize again whether the consumables are installed in place so that the equipment can execute subsequent programs. Therefore, in order for the controller to operate normally during the treatment process, it is necessary to detect and confirm whether the consumables are installed in place.

[0003] At present, the way to confirm that the pressure disc is assembled in place is to design a resilient structure in the equipment (the resilient structure includes a tension spring, a position detection block, a through-beam photoelectric switch, etc.). When the pressure disc is not assembled, the notch of the through-beam photoelectric switch is blocked and is in a disconnected state. After the pressure disc is assembled, the above-mentioned resilient structure will be pushed away from the notch of the through-beam photoelectric switch, the sensor feedback communication will be connected, and the equipment program will recognize that the pressure disc is assembled in place and start to execute subsequent programs. However, the resilient structure requires the design of multiple parts to move in conjunction with the through-beam photoelectric switch in order to realize the detection function. The structure is complex and inconvenient to use. Summary of the invention

When the controller receives the off signal, the detection member and the matching member are in a first state. When the controller receives the on signal, the detection member and the matching member are in a second state.

[0013] In one embodiment of the present application, the detection component is located in the direction of the second part of the warehouse body, a through hole of the warehouse body connects the first part and the second part, and the detection component corresponds to the clamping piece through the through hole.

[0014] In an embodiment of the present application, the first portion has a recessed area, the detection component is located in the recessed area, and an end of the detection component is lower than the first portion.

The detection component is used to detect whether the mounting piece is installed in place, and the detection component has a first state in which the mounting piece is installed in place and a second state in which the mounting piece is not installed in place. In the first state, the detection between the detection component and the clamping piece is disconnected. At this time, the mounting piece is at least partially moved into the installation space and blocks the detection component from being connected to the clamping piece, indicating that the mounting piece is installed in place in the bin body. In the second state, the detection component detects the connection to the clamping piece. At this time, the mounting piece is at least partially not moved into the installation space, indicating that the mounting piece of the detection component is not installed in place in the bin body, and the position of the mounting piece in the bin body needs to be adjusted until the mounting piece is installed in place.

[0026] The in-place detection device determines whether the installation part is installed in place by detecting the conduction or disconnection between the detection component and the fixing part.

[0037] Referring to FIG1 , the present application provides a position detection device 100. The position detection device 100 is applied to a ventricular assist device, which includes a ventricular assist host 200 and a mounting member 300. The position detection device 100 can be installed in the bin body 210 of the ventricular assist host 200, and is used to detect whether the mounting member 300 is installed in place in the bin body 210, so as to ensure that the ventricular assist device can execute subsequent procedures. FIG1 is a schematic diagram of an embodiment of the present application in which the position detection device 100 is installed in the ventricular assist host 200. It is worth noting that the position detection device 100 in the present application is mainly installed in the perfusion bin of the ventricular assist host 200. Of course, in other embodiments of the present application, the position detection device 100 can also be applied to the bin body 210 of other devices to detect whether the corresponding mounting member 300 is in place. The following text only uses the application of the position detection device 100 to the ventricular assist device as an example for explanation.

[0038] It is understandable that the current way to confirm that the pressure disc is in place is to design a resilient structure in the device. When the pressure disc is not assembled, the notch of the opposing photoelectric switch is blocked and is in a disconnected state. After the pressure disc is assembled, the above-mentioned resilient structure will be pushed away from the notch of the opposing photoelectric switch, and the sensor feedback communication will be connected. However, the resilient structure requires the design of the movement of multiple parts to cooperate with the opposing photoelectric switch in order to realize the detection function. The structure is complex and inconvenient to use. To this end, the present application provides a new type of in-place detection device 100, which can realize the effective detection of the installation part 300 in place, so as to accurately determine whether the installation part 300 is installed in place, so as to facilitate the later use of the ventricular assist device. At the same time, the structure is simple, reducing the number of parts and production process required for previous designs, and reducing the complexity of the structure, simplifying the operation and facilitating use. The specific structure of the in-place detection device 100 of one embodiment is introduced below.

[0039] Referring to FIGS. 1 to 3 , in one embodiment, the in-place detection device 100 includes a clamping member 110 and a detection assembly 120. The clamping member 110 is disposed at the first portion 211 of the bin body 210 and is surrounded by the first portion 211 to form an installation space 130. When the installation member 300 moves, the installation member 300 can at least partially move into or out of the installation space 130. The detection assembly 120 is disposed corresponding to the clamping member 110. The detection assembly 120 has a first state in which the installation member 300 is installed in place and a second state in which the installation member 300 is not installed in place. In the first state, the detection between the detection assembly 120 and the clamping member 110 is disconnected. In the second state, the detection of the detection assembly 120 is conducted to the clamping member 110. FIG. 2 is a schematic diagram of the in-place detection device 100 shown in FIG. 1 cooperating with the installation member 300 and the installation member 300 being installed in place, and FIG. 3 is a schematic diagram of the in-place detection device 100 shown in FIG. 1 cooperating with the installation member 300 and the installation member 300 being not installed in place.

[0040] The clamping member 110 is fixedly arranged in the bin body 210, and the mounting member 300 can be detachably installed in the bin body 210. The clamping member 110 can realize the installation limit of the mounting member 300, and at the same time, the clamping member 110 can also cooperate with the detection component 120 to determine whether the mounting member 300 is installed in place in the bin body 210. As shown in FIG1 , the bin body 210 is a recessed space on the ventricular assist host 200, and the bin body 210 has an inner wall (i.e., a bottom wall 213), and the clamping member 110 is arranged on the inner wall of the bin body 210. The inner wall of the bin body 210 has a first part 211 and a second part 212 arranged opposite to each other, and the following text only describes the bin body 210 having the first part 211 and the second part 212.

[0041] As shown in FIG2 , the first portion 211 is located at the top and the second portion 212 is located at the bottom. Optionally, the first portion 211 is a first surface. Of course, the first portion 211 may also include a first surface or other components to meet the requirements of setting other structures. Optionally, the second portion 212 is a second surface. Of course, the second portion 212 may also include a second surface or other components to meet the requirements of setting other structures.

[0042] The clamping member 110 is disposed on the first part 211, and is enclosed with the first part 211 to form an installation space 130. The mounting member 300 is moved and installed in the bin body 210. As shown in FIG2 , the arrow direction is the moving direction of the mounting member 300. The mounting member 300 is installed in the bin body 210 along the moving direction indicated by the arrow, and at least partially moves into the installation space 130. The mounting member 300 has a connecting portion 310, and the mounting member 300 moves into or out of the installation space 130 through the connecting portion 310. When the mounting member 300 moves, the connecting portion 310 of the mounting member 300 can move into the installation space 130, and the mounting member 300 is limited by the clamping member 110 to prevent the connecting portion 310 from coming out of the clamping member 110, thereby ensuring that the mounting member 300 is reliably installed in the bin body 210.

[0043] Of course, there may be a situation where the connection part 310 is not moved into the installation space 130, that is, the mounting member 300 is not installed in place in the bin body 210. When the connection part 310 is moved into the installation space 130, the mounting member 300 is installed in place in the bin body 210. After the mounting member 300 is installed in place in the bin body 210, the ventricular assist host 200 will perform subsequent operations. When the mounting member 300 is not installed in place in the bin body 210, it is necessary to continuously move the mounting member 300 to adjust the position of the mounting member 300 until the connection part 310 is moved into the installation space 130, otherwise the ventricular assist host 200 cannot perform subsequent operations. Moreover, when replacing the mounting member 300, the original mounting member 300 can be directly disassembled and replaced with a new mounting member 300.

[0044] Whether the mounting member 300 is installed in place in the bin body 210 is detected by the cooperation of the detection component 120 and the fixing member 110. The detection component 120 is arranged corresponding to the fixing member 110, and the detection component 120 can emit a detection signal to the fixing member 110 to detect whether there is a connection portion 310 in the installation space 130, so as to determine whether the mounting member 300 is installed in place. Specifically, the detection component 120 has a first state and a second state. When the detection component 120 is in the first state, the mounting member 300 is installed in place, and when the detection component 120 is in the second state, the mounting member 300 is not installed in place.

[0045] In the first state, the detection between the detection component 120 and the clamping component 110 is disconnected. At this time, the connection part 310 moves into the installation space 130 and blocks the detection component 120 from detecting the clamping component 110, indicating that the installation component 300 is installed in place in the warehouse body 210, as shown in Figure 2. In the second state, the detection component 120 detects the clamping component 110. At this time, the connection part 310 does not move into the installation space 130, indicating that the installation component 300 is not installed in place in the warehouse body 210, as shown in Figure 3, and the position of the installation component 300 in the warehouse body 210 needs to be adjusted until the installation component 300 is installed in place.

[0046] That is, when the connection part 310 moves into the installation space 130, the detection component 120 cannot detect the fixing member 110. At this time, the installation member 300 is installed in place. When the connection part 310 is not moved in, the detection component 120 can detect the fixing member 110. At this time, the installation member 300 is installed in place. When the installation member 300 is installed in the warehouse body 210, the installation member 300 is placed in the warehouse body 210 and is close to or in contact with the first part 211. Then, the installation member 300 is moved in the direction of the arrow shown in FIG. 2 so that the connection part 310 moves into the installation space 130. When the detection component 120 cannot detect the fixing member 110, the detection between the detection component 120 and the fixing member 110 is disconnected, the detection component 120 is in the first state, and the installation member 300 is installed in place. If the detection component 120 can detect the fixing member 110, that is, the detection component 120 is connected to the fixing member 110, the detection component 120 is in the second state, and the installation member 300 is not installed in place.

[0047] The in-place detection device 100 of the above embodiment determines whether the mounting member 300 is installed in place by conducting or disconnecting the detection component 120 and the fixing member 110. When the mounting member 300 is installed in place, the connection portion 310 disconnects the conduction between the detection component 120 and the fixing member 110. When the mounting member 300 is not installed in place, the detection component 120 can detect the conduction to the fixing member 110. In this way, effective detection of the mounting member 300 in place can be achieved to accurately determine whether the mounting member 300 is installed in place, so as to facilitate the later use of the ventricular assist device. At the same time, the in-place detection device 100 has a simple structure, reduces the number of parts and production process required for previous designs, reduces the complexity of the structure, simplifies the operation and is easy to use.

[0048] 2 and 3, in one embodiment, the detection assembly 120 is located in the direction of the second portion 212 of the warehouse body 210, the through hole of the warehouse body 210 connects the first portion 211 and the second portion 212, and the detection assembly 120 corresponds to the clamping member 110 through the through hole. In other words, the detection assembly 120 is located in the direction of the second portion 212, and is located on both sides of the warehouse body 210 with the clamping member 110, the clamping member 110 is fixed to the first portion 211 of the warehouse body 210, and the detection assembly 120 is fixedly arranged in the ventricular auxiliary host 200 and is located on one side of the second portion 212 of the warehouse body 210.

[0049] The through hole connects the first part 211 and the second part 212. At this time, the detection component 120 corresponds to the fixing member 110 through the through hole, and then the detection component 120 can detect the fixing member 110. In the first state, after the connecting part 310 moves into the installation space 130, the connecting part 310 blocks the through hole on the side of the first part 211. At this time, the detection component 120 cannot detect the fixing member 110, and the detection between the detection component 120 and the fixing member 110 is disconnected. At this time, the installation member 300 is installed in place. In the second state, the connecting part 310 is not moved into the installation space 130, and the detection component 120 detects the fixing member 110 through the through hole, so that the detection of the detection component 120 is connected to the fixing member 110. At this time, the installation member 300 is installed in place.

[0050] Optionally, the second portion 212 has a protruding limiting portion, which is arranged opposite to each other and extends in a direction away from the second portion 212. The detection member 121 is located between the two limiting portions and is limited by the two limiting portions to prevent the detection member 121 from moving relative to the position of the through hole. Optionally, the detection assembly 120 further includes a mounting plate 123, and the detection assembly 120 is fixed to the ventricular auxiliary host 200 through the mounting plate 123.

[0051] Of course, in other embodiments of the present application, the detection component 120 may also be arranged on the first part 211. That is to say, the detection component 120 is arranged on the same side as the clamping component 110. At this time, the first part 211 has a recessed area, the detection component 120 is located in the recessed area, and the end of the detection component 120 is lower than the first part 211. When the mounting member 300 is installed to the warehouse body 210, the connecting part 310 can still be moved into the installation space 130, limited by the first part 211 and the clamping component 110, and the cooperation between the detection component 120 and the clamping component 110 detects whether the connecting part 310 is installed in place. The principle is substantially the same as the principle that the detection component 120 is located on the side of the second part 212 in the above-mentioned embodiment. In the following text, only the detection component 120 is located on the side of the second part 212 as an example for explanation.

[0052] 2 and 3 , in one embodiment, the clamping member 110 has a clamping portion 114, and the mounting member 300 has a matching portion 320, which is disposed on the connecting portion 310. The clamping portion 114 and the matching portion 320 are clamped and matched to install the mounting member 300 on the bin body 210. When the connecting portion 310 moves into the installation space 130, the clamping portion 114 and the matching portion 320 are gradually matched. When the connecting portion 310 abuts against the installation space 130, the clamping portion 114 and the matching portion 320 are assembled in place, and then the mounting member 300 is installed in place in the bin body 210.

[0053] Optionally, the clamping portion 114 is a notch, and the matching portion 320 is protruding from the connecting portion 310. When the mounting member 300 moves in the bin body 210, the matching portion 320 gradually moves into the notch-shaped clamping portion 114, thereby achieving the clamping fit between the connecting portion 310 and the clamping member 110. Of course, in other embodiments of the present application, the clamping portion 114 may be protruding, and the matching portion 320 may be a notch that matches the clamping portion 114. Optionally, the clamping portion 114 and the matching portion 320 have a guiding inclined surface, and the guiding inclined surface guides the connecting portion 310 to move into the installation space 130 for fit.

[0054] 2 and 3 , in one embodiment, the clamping member 110 includes a first fixing portion 111 and a second fixing portion 112, the first fixing portion 111 is connected to the second fixing portion 112, the first fixing portion 111 is fixed to the first portion 211, and the second fixing portion 112 and the first portion 211 are arranged to form an installation space 130. The second fixing portion 112 is arranged corresponding to the detection assembly 120.

[0055] One end of the first fixing portion 111 is fixed to the first portion 211 of the bin body 210, and the other end of the first fixing portion 111 is connected to the second fixing portion 112. The second fixing portion 112 is arranged opposite to the first portion 211, and is surrounded by the first portion 211 to form an installation space 130, and the connecting portion 310 can be moved into or out of the installation space 130. Optionally, the first fixing portion 111 is arranged in a vertical direction or tilted relative to the first portion 211, so that the second fixing portion 112 can be arranged opposite to the first portion 211, which is convenient for clamping the connecting portion 310. Optionally, the second fixing portion 112 is arranged substantially parallel to the first portion 211.

[0056] Optionally, the clamping member 110 further includes a supporting portion 115, which is disposed in the installation space 130 and supports and connects the second fixing portion 112 and the second portion 212. The second fixing portion 112 can be supported by the supporting portion 115 to prevent the end of the second fixing portion 112 from settling, thereby ensuring that the connecting portion 310 can be smoothly moved into the installation space 130. At the same time, the supporting portion 115 can also limit the movement of the connecting portion 310. After the connecting portion 310 moves into the installation hole, the end of the connecting portion 310 abuts against the installation portion, indicating that the connecting portion 310 is in place in the installation space 130, and the installation member 300 is prevented from moving excessively. Optionally, the first fixing portion 111 is in the shape of a plate, a strip, a column, etc., and the second fixing portion 112 is in the shape of a plate, a strip, a column, etc.

[0057] Referring to FIG. 2 and FIG. 3 , in one embodiment, the clamping member 110 further includes a third fixing portion 113, the third fixing portion 113 is connected to the second fixing portion 112, the first portion 211 has a recessed portion 214, and the third fixing portion 113 is clamped in the recessed portion 214. The third fixing portion 113 is connected to the second fixing portion 112 or the first fixing portion 111, and the third fixing portion 113 is clamped in the recessed portion 214 of the first portion 211. In this way, the clamping member 110 can be further fixed to the bin body 210 to prevent the position of the clamping member 110 from moving in the bin body 210. Optionally, the third fixing portion 113 is provided in a plate shape or a column shape. Of course, the third fixing portion 113 can also be clamped in the recessed portion 214 by a buckle fixing method, as long as reliable fixation can be achieved and the fixation of the mounting member 300 is not affected.

[0058] Referring to Figures 2 and 3, in one embodiment, the detection assembly 120 includes a detection member 121 and a matching member 122, and the matching member 122 is arranged on the clamping member 110 and corresponds to the detection member 121; in the first state, the connecting portion 310 moves into the installation space 130 to disconnect the detection between the detection member 121 and the matching member 122, and in the second state, the detection between the detection member 121 and the matching member 122 is connected.

[0059] The detection member 121 is located in the ventricular auxiliary host 200 and is located on the second part 212 side of the chamber body 210. The matching member 122 is arranged on the fixing member 110, specifically arranged on the surface of the second fixing part 112 of the fixing member 110 facing the detection member 121. The matching member 122 corresponds to the detection member 121 through the through hole. The detection member 121 can emit a detection signal to the matching member 122, and the connection and disconnection of the detection between the detection member 121 and the matching member 122 is used to determine whether the installation member 300 is installed in place. When the connecting part 310 moves into the installation space 130, the connecting part 310 blocks the through hole on the first part 211 side, and the detection member 121 cannot detect the matching member 122 at the fixing member 110. The detection between the detection member 121 and the matching member 122 is disconnected. At this time, the detection assembly 120 is in the first state, and the installation member 300 is installed in place in the chamber body 210. When the connecting portion 310 is not moved into the installation space 130 , the detection member 121 detects the conductive fitting member 122 through the through hole. At this time, the detection assembly 120 is in the second state, and the installation member 300 is not installed in place in the bin body 210 .

[0060] In one embodiment, the detection member 121 is electrically connected to the controller of the ventricular assist device and transmits an on / off signal to the controller. When the controller receives the off signal, the detection member 121 and the matching member 122 are in a first state. When the controller receives the on signal, the detection member 121 and the matching member 122 are in a second state. When the reflective photoelectric switch detects that the reflective member is on, the reflective photoelectric switch can send a on signal to the controller. The controller determines that the mounting member 300 is not installed in place based on the on signal and displays it on the display screen of the ventricular assist device. When the reflective photoelectric switch detects that the reflective member is off, the reflective photoelectric switch can send a off signal to the controller. The controller determines that the mounting member 300 is installed in place based on the off signal and displays it on the display screen of the ventricular assist device.

[0061] Referring to FIG. 2 and FIG. 3, in one embodiment of the present application, the detection member 121 is a reflective photoelectric switch, and the matching member 122 is a reflective member. In the first state, the reflective photoelectric switch emits light to the connecting portion 310 and performs diffuse reflection. In the second state, the reflective photoelectric switch emits light and projects it onto the reflective member, and the reflective member reflects the light to the reflective photoelectric switch. In other words, in this embodiment, whether the mounting member 300 is installed in place is determined by whether the light is reflected back to the reflective photoelectric switch. Optionally, the reflective member is a reflective paper or a reflective flat plate.

[0062] When the connection part 310 is moved into the installation space 130, the reflective photoelectric switch emits light to the connection part 310. The surface of the connection part 310 is relatively rough, which can cause diffuse reflection of the light. At this time, the light received by the reflective photoelectric switch does not meet the setting requirements of the reflective photoelectric switch, and the detection between the detection member 121 and the matching member 122 is disconnected. At this time, the detection assembly 120 is in the first state, and the mounting member 300 is installed in place in the warehouse body 210. When the connection part 310 is not moved into the installation space 130, the reflective photoelectric switch emits light and projects it on the reflective member, and the reflective member reflects the light to the reflective photoelectric switch. At this time, the light received by the reflective photoelectric switch can meet the setting requirements, and the detection member 121 conducts the matching member 122 through the through hole detection. At this time, the detection assembly 120 is in the second state, and the mounting member 300 is not installed in place in the warehouse body 210.

[0063] Specifically, when the mounting member 300 is not installed or not installed in place, the transmission line of the reflective photoelectric switch reaches the reflective member and is reflected back to the reflective optical switch. After the reflective optical switch receives the light transmitted back, the intensity of the refracted light can meet the setting requirements of the reflective optical switch. The controller receives the conduction signal and determines that the mounting member 300 is not installed in place. When the mounting member 300 is installed in place along the arrow direction shown in FIG. 2, the connecting portion 310 will shield the reflective member. At this time, the light emitted by the reflective optical switch directly hits the connecting portion 310. Since the surface of the connecting portion 310 is relatively rough, the light is diffusely scattered. Therefore, the intensity of the refracted light cannot meet the setting requirements of the reflective optical switch. The controller receives the disconnection signal and determines that the mounting member 300 is installed in place.

[0064] It is worth noting that the setting requirement here refers to the amount of light received by the reflective photoelectric switch. When the reflector reflects the light to the reflective photoelectric switch, most of the rays emitted by the reflective photoelectric switch can be reflected, thereby ensuring that the reflective photoelectric switch has enough light to meet the setting requirements, so that the reflective photoelectric switch can send a conduction signal, indicating that the mounting member 300 is not installed in place. If the light is diffusely reflected by the connecting portion 310, the light will diverge, and no light or very little light will be received by the reflective photoelectric switch. At this time, the light received by the reflective photoelectric switch cannot meet the set pressure, so the reflective photoelectric switch sends a disconnection signal.

[0065] In another embodiment of the present application, the detection member 121 is a sensor, and the matching member 122 is an induction member. In the first state, the sensor and the induction member are disconnected from each other, and in the second state, the sensor and the induction member are matched with each other. When the sensor can sense the induction member, the detection of the detection member 121 and the matching member 122 is conducted, and the installation member 300 is not installed in place. When the sensor cannot sense the induction member, the detection of the detection member 121 and the matching member 122 is disconnected, and the installation member 300 is installed in place. Of course, the induction member can also be separately arranged in the connecting part 310 and the fixing member 110, and the induction member of the connecting part 310 and the induction member of the fixing member 110 will generate different induction signals with the sensor, so that the sensor can identify and distinguish the induction member of the connecting part 310 and the induction member of the fixing member 110, which is convenient for detecting whether the installation member 300 is installed in place.

[0066] Of course, in other embodiments of the present application, the detection member 121 may also be an infrared emitting member, and the reflecting member may be an infrared receiving member. When the infrared emitting member can receive the signal emitted by the infrared receiving member, the detection member 121 and the matching member 122 are detected to be connected, and the mounting member 300 is not installed in place. When the infrared emitting member cannot receive the signal emitted by the infrared receiving member, the detection member 121 and the matching member 122 are detected to be disconnected, and the mounting member 300 is installed in place. It is worth noting that the detection member 121 and the matching member 122 may also be other structural forms that can realize in-place detection, which will not be repeated here.

[0067] The in-place detection device 100 of the present application determines whether the mounting member 300 is in place by conducting or disconnecting the detection component 120 and the fixing member 110. When the mounting member 300 is in place, the connection portion 310 disconnects the conduction between the detection component 120 and the fixing member 110. When the mounting member 300 is not in place, the detection component 120 can be connected to the fixing member 110. In this way, effective detection of the mounting member 300 in place can be achieved to accurately determine whether the mounting member 300 is in place, so as to facilitate the later use of the ventricular assist device.

[0068] At the same time, the in-place detection device 100 has a simple structure, which reduces the number of parts and production process required for the design, and does not use parts with fatigue attenuation such as springs, which reduces the complexity of the structure and simplifies the operation for ease of use. Moreover, the in-place detection device 100 uses a reflective photoelectric switch to replace a beam photoelectric switch, thereby eliminating the previous complex solution, designing a simple and practical in-place detection device 100, increasing the reliability of product operation, and reducing the probability of after-sales repairs. After the in-place detection device 100 is applied to the main unit of the ventricular assist device, the number of parts and assembly procedures are reduced on the original design, and a simple and practical in-place detection structure is designed, which simplifies the process, reduces the manufacturing and installation costs; and reduces the failure risk of parts and the probability of after-sales repairs.

[0069] 1 , the present application also provides a ventricular assist device, including a mounting member 300, a bin body 210, and a position detection device 100 as in any of the above embodiments, wherein the mounting member 300 is detachably mounted in the bin body 210, and the position detection device 100 is used to detect whether the mounting member 300 is in place in the bin body 210. After the ventricular assist device of the present application adopts the above position detection device 100, it can effectively detect whether the mounting member 300 is in place, so as to accurately determine whether the mounting member 300 is in place, so as to facilitate the later use of the ventricular assist device.

[0070] 2 and 3 , in one embodiment, the mounting member 300 has a connecting portion 310, which is disposed at the bottom of the mounting member 300 and extends radially toward the outside of the mounting member 300, and the connecting portion 310 is in position with the position detection device 100. In this way, the mounting member 300 can be easily matched with the clamping member 110.

[0071] Referring to FIG. 1 , in one embodiment, the warehouse body 210 has a bottom wall 213, and the position detection device 100 is disposed on the bottom wall 213. That is, the bottom wall 213 has a first portion 211 and a second portion 212, so that the mounting member 300 can be fixed to the bottom wall 213 to ensure reliable fixation. Of course, in other embodiments of the present application, the position detection device 100 can also be disposed on the side wall of the warehouse body 210.

[0072] Referring to Figures 2 and 3, in one embodiment, the ventricular assist device also includes a ventricular assist host 200 and a perfusion box. The ventricular assist host 200 has a perfusion chamber which is a chamber body 210. The perfusion chamber is recessed in the surface of the ventricular assist host 200. An in-place detection device 100 is disposed in the ventricular assist host 200. The inner wall of the perfusion chamber has a through hole, which is disposed corresponding to the in-place detection device 100. The mounting member 300 is a pressure disc. When the pressure disc is mounted on the perfusion chamber, the in-place detection device 100 is used to detect whether the pressure disc is installed in place.

[0073] During the self-test of the ventricular assist host 200, consumables need to be installed in the perfusion chamber (the consumables include a perfusion box and a pressure disc, and the assembly process is to install the perfusion box first and then the pressure disc). The controller can only start executing subsequent programs after it recognizes that all the consumables have been assembled. In addition, during the operation of the controller, there is a situation where the equipment is paused to replace a whole set of consumables. When new consumables are installed, the perfusion chamber needs to identify again whether the consumables are installed in place so that the equipment can execute subsequent programs. After the ventricular assist device of the present application adopts the above-mentioned in-place detection device 100, it can achieve effective detection of the installation component 300 in place, so as to accurately determine whether the installation component 300 is installed in place, so as to facilitate the later use of the ventricular assist device.

[0074] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
