Description

Technical Field

[0001] This application belongs to the field of medical devices, and in particular relates to a medical controller. Background Technology

[0002] In the field of medical technology, ventricular assist devices (VADs) are used to provide hemodynamics for patients with heart failure, helping the heart pump blood throughout the body. A VAD consists of a distal catheter pump and a proximal controller, operated by the physician. The catheter pump is inserted percutaneously into the patient's blood vessel and positioned in the left ventricle. Activation of the controller initiates the pump's operation, allowing blood to enter through the inlet and exit through the outlet. The pump thus fulfills its function of pumping blood from the left ventricle to the aorta and then to the rest of the body, replacing the heart's role in this process.

[0003] Throughout the procedure, the doctor can control the remote catheter pump via a controller on the operating terminal. When the controller adjusts the parameters of the catheter pump, such as current and speed, the catheter pump will make corresponding parameter changes based on the controller's signals. Furthermore, the controller transmits the relevant parameter data to the controller's user interface, allowing the doctor to obtain specific data and make timely adjustments based on the status of the catheter pump to help the patient's cardiac indicators return to normal.

[0004] In addition, the controller is also used to alert and warn doctors. When the catheter pump is in an abnormal state, the catheter pump will transmit an abnormal signal to the controller, and the indicator light on the controller will light up. Traditional controllers have poor display effects on the main unit, and the warning effect is not obvious, or the indicator light is glaring and can damage the eyes. Summary of the Invention

[0057] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0058] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0059] One embodiment of this application provides a medical controller 10. (See also...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 The medical controller 10 is used to regulate the catheter pump. The medical controller 10 includes a housing 11 and a prompting mechanism 12. The housing 11 includes a front housing 111; the prompting mechanism 12 is installed inside the front housing 111 and includes a light guide post 121 and a light-emitting element 122. The light guide post 121 is embedded in the front housing 111. The first end a of the light guide post 121 in the first extension direction 1001 is exposed outside the housing 11 and has a first inclined surface 1211 and a second inclined surface 1212 arranged at an angle. The second end b of the light guide post 121 in the first extension direction 1001 has a third inclined surface 1213, which is directly opposite to the light-emitting element 122. The third inclined surface 1213 is not parallel to the first inclined surface 1211 and / or the third inclined surface 1213 is not parallel to the second inclined surface 1212.

[0060] Specifically, the prompting mechanism 12 is installed inside the front housing 111, with a portion protruding from the front housing 111 of the medical controller 10. This prompting mechanism 12 is used to alert the doctor when the medical controller 10 is in an abnormal state. The prompting mechanism 12 includes a light guide post 121 and a light-emitting element 122. The light guide post 121 is embedded in the front housing 111, and its first extending direction 1001 is from the inside of the front housing 111 to the outside. The light guide post 121 has a first end a and a second end b arranged opposite each other in the first extending direction 1001. The second end b is the light incident end, and the first end a is the light emitting end. The first end a is exposed outside the front housing 111, and the first end a forms a first inclined surface 1211 and a second inclined surface 1212 arranged at an angle. The second end b has a third inclined surface 1213, and the third inclined surface 1213 is positioned directly opposite the light-emitting element 122. That is, the light on the light-emitting element 122 enters the light guide column 121 obliquely through the third inclined surface 1213. After reflection and refraction inside the light guide column 121, the light is emitted from the first inclined surface 1211 and the second inclined surface 1212.

[0061] contrast Figure 5 In (1) and (2), the light guide column 121 of this application is designed as in (1). In (1), the first inclined surface 1211 and the second inclined surface 1212 of the light guide column 121 are set at an angle; in (2), the first inclined surface 1211 and the second inclined surface 1212 of the light guide column 121 are set coplanarly, and the side of the light guide column 121 embedded in the front shell 111 is set as a plane. Compared with (2), the design of the first inclined surface 1211 and the second inclined surface 1212 of the light guide column 121 in (1) significantly increases the display range angle of the light, making it easier for doctors to identify the light emitted by the prompting mechanism 12.

[0062] contrast Figure 6 (3), (4), and (5). The light guide post 121 of this application is designed as (3), where the third inclined surface 1213 is not parallel to the first inclined surface 1211, and the third inclined surface 1213 is not parallel to the second inclined surface 1212; in (4), the third inclined surface 1213 is parallel to the first inclined surface 1211; and in (5), the third inclined surface 1213 is parallel to the second inclined surface 1212. Comparing (4) and (5), in (3), the third inclined surface 1213 of the light guide post 121 of this application is not parallel to the first inclined surface 1211 and the second inclined surface 1212. Light can undergo multiple refractions and diffuse reflections within the light guide post 121, which can reduce the probability of light directly exiting the light guide post 121, making the light guide post 121 have a better soft light effect on the light-emitting element 122 and the light more uniform.

[0063] In one embodiment of this application, the included angle between the first inclined plane 1211 and the second inclined plane 1212 is 90-150°. Preferably, in this embodiment, the included angle between the first inclined plane 1211 and the second inclined plane 1212 is designed to be 120°. (Refer to...) Figure 4 The front shell 111 includes a first shell 1111 and a second shell 1112, with an included angle of 120° between the first shell 1111 and the second shell 1112. A light guide post 121 is embedded at the junction of the first shell 1111 and the second shell 1112. Designing the included angle of the first inclined surface 1211 and the second inclined surface 1212 to 120° ensures that the first inclined surface 1211 is coplanar with the outer wall of the first shell 1111, and the second inclined surface 1212 is coplanar with the outer wall of the second shell 1112. The prompting mechanism 12 is partially exposed in the front shell 111 of the medical controller 10, and is used to prompt the doctor when the medical controller 10 is in an abnormal state.

[0064] Specifically, the light-emitting element 122 includes a plurality of LED beads 1221 arranged in a straight line, or an array of LED beads 1221 forming an LED bead matrix, which is not limited here.

[0065] In one embodiment of this application, reference is made to Figure 3 The third inclined plane 1213 is not perpendicular to the first extending direction 1001. If the third inclined plane 1213 were designed to be perpendicular to the first extending direction 1001, such as... Figure 7 The probability of light rays directly exiting the light guide post 121 increases. The third inclined surface 1213 of this application is not perpendicular to the first extension direction 1001, which allows light rays to undergo multiple refractions and diffuse reflections within the light guide post 121, further reducing the probability of light rays directly exiting the light guide post 121, and further enhancing the soft light effect of the light guide post 121 on the light-emitting element 122.

[0066] In one embodiment of this application, the light guide post 121 is transparent and frosted. The light guide post 121 is made of polycarbonate material with a light-diffusing powder, and has a slightly whitish transparent frosted appearance, making the internal components of the medical controller 10 invisible from the outside, and also ensuring more uniform light guidance to the light-emitting element 122. In other embodiments, the light guide post 121 may also be made of milky white acrylic.

[0067] In one embodiment of this application, reference is made to Figure 1 and Figure 8 The housing 11 also includes a middle housing 112 and a rear housing 113. The middle housing 112 is open at both ends. The front housing 111 covers one open end of the middle housing 112, and the rear housing 113 covers the other open end of the middle housing 112. The front housing 111, the middle housing 112 and the rear housing 113 enclose each other to form a cavity for accommodating electronic components.

[0068] In one embodiment of this application, reference is made to... Figure 1 , Figure 9 , Figure 10 and Figure 11The bottom of the middle shell 112 includes a locking connector 1121; the medical controller 10 also includes a movable platform 13, which is provided with a plug-in hole 131 and a locking mechanism 132; after the locking connector 1121 is inserted into the plug-in hole 131, it engages with the locking mechanism 132 to lock the shell 11. Specifically, the medical controller 10 also includes a movable platform 13, the shape of which is not limited, and can be a trolley platform, a movable cabinet platform, a movable desktop, etc. The shell 11 is inserted into the plug-in hole 131 on the movable platform 13 through the locking connector 1121 at the bottom of the middle shell 112, and engages with the locking mechanism 132 designed on the side of the movable platform 13 opposite to the shell 11, thereby locking the shell 11 and the movable platform 13 to keep the shell 11 stable and prevent it from falling when moving or transporting it.

[0069] In one embodiment of this application, reference is made to... Figure 11 , Figure 12 and Figure 13 The locking connector 1121 has a protrusion 1121a at the end away from the middle shell 112, and a snap-fit ​​groove 1121b is formed between the protrusion 1121a and the bottom of the shell 11. The movable platform 13 has a mounting groove 133 on the side facing away from the shell 11, and the mounting groove 133 communicates with the insertion hole 131. The locking mechanism 132 includes two snap-fit ​​parts 1321 and a first elastic member 1322. The two snap-fit ​​parts 1321 are arranged opposite to each other and are movably disposed in the mounting groove 133. The snap-fit ​​parts 1321 can be engaged in the snap-fit ​​groove 1121b after the protrusion 1121a extends into the mounting groove 133 through the insertion hole 131; the first elastic member 1322 drives the two snap-fit ​​parts 1321 to move closer to each other.

[0070] Specifically, refer to Figure 12 The locking connector 1121 has a protrusion 1121a and a snap-fit ​​groove 1121b. (Refer to...) Figure 13 The movable platform 13 has a insertion hole 131 on the side facing the housing 11 and a mounting groove 133 on the side facing away from the housing 11, which communicates with the insertion hole 131. The locking mechanism 132 includes two latching parts 1321 and a first elastic member 1322. The two latching parts 1321 are arranged opposite each other and are movably disposed in the mounting groove 133. The first elastic member 1322 drives the two latching parts 1321 to move closer together. After the protrusion 1121a of the locking connector 1121 extends into the mounting groove 133 through the insertion hole 131, the first elastic member 1322 deforms, and the two latching parts 1321 move away from each other. The latching groove 1121b of the locking connector 1121 engages with the two latching parts 1321 to lock the housing 11.

[0071] In one embodiment of this application, the protrusion 1121a has a guide surface A on the side facing away from the housing 11. When the locking connector 1121 extends into the mounting groove 133, the guide surface A contacts the snap-fit ​​portion 1321 and overcomes the elastic force of the first elastic member 1322, thereby driving the two snap-fit ​​portions 1321 away from each other so that the protrusion 1121a can be snapped in. Specifically, the protrusion 1121a has a guide surface A, which is designed with an incline. This facilitates the protrusion 1121a to overcome the elastic force of the first elastic member 1322 after it enters the insertion hole 131, thereby driving the two snap-fit ​​portions 1321 away from each other so that the protrusion 1121a can be snapped in.

[0072] In one embodiment of this application, reference is made to... Figure 13 , Figure 14 and Figure 15 The locking mechanism 132 also includes a movable plate 134 and a handle 135. The movable plate 134 is slidably disposed in the mounting groove 133. A strip groove 1341 is provided on the movable plate 134, which is positioned opposite to the insertion hole 131. Two latching parts 1321 are movably disposed on the movable plate 134. The movable plate 134 can slide along the first direction x to move the latching parts 1321 away from the insertion hole 131 and disengage from the locking connector 1121. The movable plate 134 can slide along the second direction y, which is opposite to the first direction x, to move the latching parts 1321 to a position opposite to the insertion hole 131. The handle 135 is connected to the movable plate 134 and extends to the edge of the movable table 13.

[0073] Specifically, the movable plate 134 is provided with a strip groove 1341, which is positioned directly opposite the insertion hole 131. Two snap-fit ​​parts 1321 are movably mounted on the movable plate 134, and a handle 135 is fixedly connected to the movable plate 134. (Refer to reference...) Figure 13 and Figure 15 When the handle 135 is pulled in the first direction x, the movable plate 134 slides along the first direction x, causing the locking part 1321 to move away from the insertion hole 131 and disengage from the locking connector 1121, thus achieving the unlocking purpose. At this time, the housing 11 can be removed. (Refer to reference) Figure 13 and Figure 14 After the handle 135 is released, the handle 135 returns to its original position, and the movable plate 134 slides along the second direction y, which is opposite to the first direction x, so that the locking part 1321 moves to the position directly opposite the insertion hole 131.

[0074] In one embodiment of this application, the locking mechanism 132 further includes a second elastic element 136. The second elastic element 136 is disposed in the mounting groove 133, with one end connected to the movable plate 134 facing the first direction x, and the other end connected to the inner wall of the mounting groove 133. The second elastic element 136 drives the movable plate 134 to move in the second direction y. Specifically, when the handle 135 is pulled in the first direction x, the movable plate 134 slides along the first direction x, compressing the second elastic element 136. The locking part 1321 moves away from the insertion hole 131 and disengages from the locking connector 1121, achieving the unlocking purpose. At this time, the housing 11 can be removed. When the handle 135 is released, the handle 135 returns to its original position, the second elastic element 136 regains its elasticity, and drives the movable plate 134 to slide in the second direction y, causing the locking part 1321 to move to a position directly opposite the insertion hole 131.

[0075] In one embodiment of this application, the latching part 1321 is rotatably disposed on the movable plate 134, and the first elastic element 1322 is a torsion spring, which drives the two latching parts 1321 to rotate relative to each other and move closer; or, the two latching parts 1321 are slidably disposed relative to each other on the movable plate 134, and the first elastic element 1322 is a spring, which drives the two latching parts 1321 to slide relative to each other and move closer.

[0076] Specifically, refer to Figure 13 When the snap-fit ​​part 1321 is rotatably mounted on the movable plate 134, the first elastic element 1322, which is a torsion spring, can be rotatably mounted on the movable plate 134. When the locking connector 1121 extends from the insertion hole 131 into the strip groove 1341 of the movable plate 134, the torsion spring deforms, and the two snap-fit ​​parts 1321 rotate toward the side away from the movable plate 134. The locking connector 1121 smoothly inserts into the insertion hole 131, and the two snap-fit ​​parts 1321 engage with the snap-fit ​​groove 1121b of the locking connector 1121.

[0077] Reference Figure 16 When the two locking parts 1321 are slidably disposed relative to each other on the movable plate 134, the first elastic element 1322 is a spring, which can achieve relative sliding disposal on the movable plate 134. When the locking connector 1121 extends from the insertion hole 131 into the strip groove 1341 of the movable plate 134, the spring deforms, and the two locking parts 1321 move according to... Figure 16 The two parts 1321 are separated to the sides and move away from each other in the direction of the middle arrow. The locking connector 1121 is smoothly inserted into the insertion hole 131, and the two snap-fit ​​parts 1321 snap into the snap-fit ​​groove 1121b of the locking connector 1121.

[0078] In one embodiment of this application, the movable plate 134 has a first limiting groove 1342 extending along its sliding direction, and a limiting block 1323 is provided at the bottom 13 of the movable platform, the limiting block 1323 being located within the first limiting groove 1342. The limiting block 1323, located within the first limiting groove 1342, can limit the movement distance of the handle 135, allowing the maximum pulling force of the handle 135 to be designed to be 5-30N for ease of use. Simultaneously, it prevents the movement direction of the handle 135 from deviating.

[0079] In one embodiment of this application, reference is made to... Figure 8 , Figure 9 and Figure 10 The bottom of the middle shell 112 is also provided with at least one foot pad 1122, and the movable platform 13 is provided with a corresponding receiving groove 137. After the locking connector 1121 is inserted into the insertion hole 131 and engaged with the locking mechanism 132, the foot pad 1122 abuts against the receiving groove 137, which can improve the stability of the shell 11 placed on the movable platform 13.

[0080] In one embodiment of this application, the medical controller 10 includes a switching mechanism 14, which is disposed at one end of the front housing 111. The switching mechanism 14 includes a front cover 141, a suction pad 142, a pop-up mechanism 143, and a micro switch 144. The front cover 141 is rotatably disposed on the front housing 111 and can rotate to move closer to or further away from the front housing 111. The suction pad 142 is disposed on the front cover 141, and the pop-up mechanism 143 and the micro switch 144 are fixedly disposed on the front housing 111. Microswitch 144 is connected to the main control unit and is used to transmit signals to the main control unit. When the front cover 141 is placed on the front shell 111, the pop-up device 143 attracts the suction plate 142. When the front cover 141 is pressed, the pop-up device 143 moves away from the front cover 141. When the pop-up device 143 reaches the first position, the pop-up device 143 and the suction plate 142 are completely attracted. The front cover 141 presses the microswitch 144, and the microswitch 144 triggers the signal of the main control unit, indicating that the front cover 141 is in the closed state.

[0081] Specifically, the switching mechanism 14 of the medical controller 10 is used to house the irrigation box and the bubble sensor, and is used to detect the switching signal and transmit the switching signal to the main control unit when the two are disassembled. The irrigation box is used to provide power and deliver irrigation fluid to the catheter pump to provide an anticoagulant effect, and the bubble sensor is used to detect the pressure of the irrigation fluid. (Refer to...) Figure 17 , Figure 18 and Figure 19The front cover 141, along with the suction plate 142, the pop-up mechanism 143, and the micro switch 144, provides feedback for opening and closing the front cover 141. The suction plate 142 is mounted on the front cover 141, while the pop-up mechanism 143 and the micro switch 144 are fixedly mounted on the front shell 111. The pop-up mechanism 143 contains a movable part 1431, which has a magnetic attraction device for attracting the suction plate 142. The micro switch 144 is connected to the main control unit and is used to transmit signals to the main control unit.

[0082] When the front cover 141 is placed on the front shell 111, the front cover 141 presses down on the movable part 1431 at the front end of the pop-up device 143. The movable part 1431 is compressed and simultaneously attracts the suction plate 142. When the front cover 141 is pressed down, the movable part 1431 moves away from the front cover 141. When the movable part 1431 of the pop-up device 143 reaches the first position, the pop-up device 143 and the suction plate 142 are completely attracted. At the same time, the front cover 141 presses the micro switch 144. The micro switch 144 triggers the locking signal of the main control unit, indicating that the front cover 141 is in the closed state.

[0083] In one embodiment of this application, after the pop-up device 143 reaches the first position, the front cover 141 is pressed further, and the pop-up device 143 reaches the second position. The pop-up device 143 pops open to the side of the front cover 141, the front cover 141 moves away from the micro switch, the micro switch 144 resets, the signal of the main control unit disappears, indicating that the front cover 141 is in the open state; wherein, the distance between the second position and the front cover 141 is greater than the distance between the first position and the front cover 141.

[0084] Specifically, after the pop-up release 143 reaches the first position, the front cover 141 is in the closed state. If the front cover 141 is pressed further, causing the pop-up release 143 to reach the second position, the pop-up release 143 will pop open to the side of the front cover 141, the front cover 141 will move away from the micro switch 144, the micro switch 144 will reset, the locking signal of the main control unit will disappear, indicating that the front cover 141 is in the open state.

[0085] It should be noted that, referring to Figure 20 The front shell 111 has a first buckle 1113, and the front cover 141 has a pivot 1411 and a ring 1412. The pivot 1411 passes through the ring 1412, and the exposed part of the pivot 1411 is engaged with the first buckle 1113. This allows the pivot 1411 to be hidden inside the front shell 111. The slot is hidden at the bottom, and there are no seams when viewed from the front of the shell 11, making it simple and beautiful.

[0086] In one embodiment of this application, reference is made to Figure 21 The front cover 141 includes a first limiting part 1413. When the front cover 141 is opened to the maximum angle, the first limiting part 1413 abuts against the front shell 111, thereby limiting the front cover 141 when it is opened.

[0087] In one embodiment of this application, reference is made to Figure 22 The front shell 111 has snap-fit ​​wings 1114 on both sides facing the middle shell 112, and the middle shell 112 has second limiting grooves 1123 on both sides facing the front shell 111. The snap-fit ​​wings 1114 and the second limiting grooves 1123 are interlocked to lock the front shell 111 and the middle shell 112. The interlocking of the snap-fit ​​wings 1114 and the second limiting grooves 1123 facilitates the installation guidance of the front shell 111 and the middle shell 112 and increases the connection strength, while also concealing the assembly gap.

[0088] In one embodiment of this application, reference is made to Figure 23 A fan structure is installed within the accommodating cavity. An air inlet 1124 is located at the bottom of the middle shell 112, and an air outlet 1131 is located on the rear shell 113. The fan structure draws air in through the air inlet 1124 and exhausts it through the air outlet 1131. Specifically, a fan structure is installed within the accommodating cavity formed by the front shell 111, middle shell 112, and rear shell 113. The fan structure draws air in through the air inlet 1124 and exhausts it through the air outlet 1131 to achieve active heat dissipation.

[0089] In one embodiment of this application, reference is made to Figure 24 The air outlet 1131 is set to open at an angle downwards. This angled downwards design ensures that when the operator stands behind the medical control unit 10, the dissipated air is exhausted downwards from the air outlet 1131, avoiding direct airflow onto the human body and causing discomfort.

[0090] In one embodiment of this application, the front shell 111 has a first water-guiding slope 1115, and the middle shell 112 has a second water-guiding slope 1125. By designing the first and second water-guiding slopes 1115 and 1125, water can flow down along these slopes when external water accumulates. Even if a small amount of liquid enters the medical control 10, it can be discharged through the air inlet 1124 at the bottom of the middle shell 112. Similarly, the air outlet 1131 of the rear shell 113 is angled downwards to facilitate water flow and prevent some water from entering the medical control 10. It should be noted that, considering waterproofing, the edge openings or devices of the medical control 10 are all sealed.

[0091] In one embodiment of this application, a handle 1126 is provided on the top of the middle shell 112, and the handle 1126 is integrally formed with the middle shell 112. A first reinforcing rib 1127 is provided on the side of the middle shell 112 facing the handle 1126; a second reinforcing rib 1128 extending to both sides of the middle shell 112 is provided on the side of the middle shell 112 away from the handle 1126. Specifically, the integral forming design of the handle 1126 and the middle shell 112 eliminates the need for an additional handle structure on the medical control 10. The integral forming design helps improve the waterproof performance of the medical control 10 and is also more aesthetically pleasing. The first reinforcing rib 1127 on the side of the middle shell 112 facing the handle 1126 has a thickness that can be designed to be 1mm-5mm, which can prevent stress concentration when lifting the shell 11. The second reinforcing rib 1128 on the side of the middle shell 112 away from the handle 1126 can distribute the force to the entire body when lifting the shell 11.

[0092] In other embodiments, two lug structures can be designed instead of handle 1126, or a flip-up handle can be installed, while still ensuring a seamless housing design.

[0093] In summary, the medical controller 10 used in this application includes a prompting mechanism 12, which includes a light guide post 121. The light guide post 121 includes a first inclined surface 1211 and a second inclined surface 1212 designed at an angle to each other, and a third inclined surface 1213 is not parallel to the first inclined surface 1211, nor parallel to the second inclined surface 1212. This increases the light emission range of the prompting mechanism 12, making it easy to identify while providing soft and uniform light. The locking connector 1121 and the locking mechanism 132 of the medical controller 10 work together to stably fix the housing 11 to the movable table 13, facilitating the doctor's movement and operation of the device.

[0094] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
