Description

Technical Field

[0001] The utility model relates to the technical field of safety testing of artificial assisted heart controllers, in particular to a withstand voltage testing device for artificial assisted heart controllers. Background Art

[0002] To ensure that the artificial heart controller (hereinafter referred to as the controller) can still operate normally and maintain safety performance in potential high-voltage situations, such as sudden power surges or failures of external electrical equipment, and to ensure that the controller can operate normally without damage or danger, the controller must undergo high-voltage withstand testing with a test voltage of up to approximately 4kV.

[0003] The existing testing method relies on manual operation, where the operator, wearing insulating gloves, holds a test gun in contact with the outer casing of the product's controller before conducting the test. This testing method poses significant safety risks and also poses risks such as poor contact during operation, resulting in inconsistent and unstable controller withstand voltage tests.

[0004] Therefore, how to improve the withstand voltage test method of the controller has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The utility model aims to solve the technical problems existing in the prior art and provides a pressure-resistant test device for an artificial assisted heart controller, which can improve the consistency of the pressure-resistant test of the controller.

[0006] The technical solution of the present utility model is achieved through the following measures: a pressure test device for an artificial assisted heart controller, comprising a base plate and a support column arranged on the base plate; a test assembly is provided on the support column; the test assembly includes a support arm, one end of the support arm is socketed with the support column, and the other end is provided with a test unit; the test unit includes a probe slidably arranged with the support arm.

[0007] Furthermore, the support column is also provided with a first limiting unit.

[0008] Furthermore, the test unit includes a limiting column, the limiting column is sleeved with a shaft sleeve, and the lower end of the limiting column is connected to the measuring head through an insulating sleeve.

[0009] Furthermore, an indicator light is provided on the support arm.

[0010] Furthermore, a second limiting unit is provided on the bottom plate.

[0011] The utility model relies on a support arm arranged on a support column, and a probe is arranged on the support arm. During the test process, the probe is relied on to maintain contact with the outer shell of the controller, replacing the existing operation mode in which the operator holds a test gun in contact with the outer shell of the controller, which greatly reduces the risk of electric shock for the operator during the test process, and at the same time reduces factors such as poor contact and test misoperation caused by human factors during the test process, thereby ensuring the consistency and stability of the controller voltage resistance test process.

[0020] In the description of the present utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0021] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0022] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] like Figures 1-4 As shown, the pressure test device of an artificial assisted heart controller 100 involved in this embodiment includes a base plate 110 and a support column 200 arranged on the base plate 110; a test component is provided on the support column 200; the test component includes a support arm 210, one end of the support arm 210 is connected to the support column 200, and the other end is provided with a test unit 220; the test unit 220 includes a probe 221 slidably set with the support arm 210.

[0024] In the present invention, the base plate 110 provides a stable support platform, and the support column 200 is longitudinally arranged on the base plate 110. A cylindrical support column 200 can be selected to provide support and positioning for the test assembly. The design of the support column 200 can be adjusted as needed to accommodate cardiac controllers 100 of different shapes and sizes. A test assembly is slidably arranged on the support column 200. The test assembly includes a horizontally arranged support arm 210. The support arm 210 has a block-shaped structure with a rectangular or square cross-section. Through holes are provided on both sides of the support arm 210. The side closest to the support column 200 is connected to the support column 200 through the through hole, ensuring the stability and accuracy of the test unit 220. The test unit 220 is installed in the through hole on the other side of the support arm 210 for performing a pressure test. The test unit 220 includes a slidable probe 221 for maintaining contact with the outer shell of the cardiac controller 100.

[0025] During the test, the probe 221 is electrically connected to the test voltage. The connection method between the probe 221 and the test voltage is conventional in the art. For example, electrodes can be provided on the probe 221 and the electrodes can be electrically connected to the test voltage using existing connection methods. When the withstand voltage test is not being performed, the probe 221 is disconnected from the test voltage. At this time, the probe 221 is in a free state, and the end of the probe 221 is lower than the upper surface of the controller 100. When the withstand voltage test is required, the probe 221 is raised so that its end is higher than the upper surface of the controller 100, and then the support arm 210 is rotated. The probe 221 is then freed again. At this time, the probe 221 abuts against the upper surface of the controller 100. Finally, the probe 221 is electrically connected to the test voltage, and the withstand voltage test can be performed.

[0026] This design replaces the traditional handheld test gun method, effectively reducing the risk of electric shock to operators and preventing the impact of human factors on the testing process, such as poor contact and misoperation. This ensures the reliability of test results and reduces the risk of operator error and accidents during testing.

[0027] In other embodiments of the present application, a first limiting unit 201 is further provided on the support column 200. Figures 1-4As shown, the first limiting unit 201 adopts a clamp structure, specifically including a first limiting plate, a through hole and a notch are provided on the right side of the first limiting plate, and a fastening screw is also provided at the notch. The first limiting plate is sleeved on the support column 200 through the through hole, and then the fastening screw is locked to fix the relative position of the first limiting plate and the support column 200. In the present application, the first limiting unit 201 is used to limit the up and down movement direction of the support arm 210. When it is suitable for different models of controllers 100, the relative position of the first limiting plate and the support column 200 is adjusted, thereby controlling the relative position of the support arm 210. In the present utility model, the first limiting unit 201 is used to limit the up and down movement direction of the support arm 210 to avoid changes in the test results caused by changes in the position of the support arm 210 during the test, thereby ensuring the accuracy of the test results.

[0028] In other embodiments of this application, refer to Figure 5 As shown, the test unit 220 includes a limit column 222, which is sleeved with a shaft sleeve 223. The lower end of the limit column 222 is connected to the probe 221 through an insulating sleeve. The limit column 222 is used to limit the upward movement of the probe 221. Different limit columns 222 can be replaced according to the different controllers 100 being tested. The shaft sleeve 223 is fixedly set in the through hole of the support arm 210 to provide support and positioning. An insulating sleeve is also provided at the lower end of the shaft sleeve 223, wherein one end of the insulating sleeve is connected to the probe 221, and the other end of the insulating sleeve is sleeved with the limit column 222. By providing insulating sleeves at intervals in the test unit 220, the high voltage on the probe 221 is prevented from being transmitted to the support arm 210, thereby improving the safety of the device. In other embodiments, a spring 224 is further provided between the insulating sleeve and the shaft sleeve 223, wherein both ends of the spring 224 are fixedly connected to the insulating sleeve and the shaft sleeve 223 respectively. When the spring 224 is in a free state, the end of the probe 221 is lower than the upper surface of the controller 100. When the spring 224 is in a compressed state, the end of the probe 221 is higher than the upper surface of the controller 100. By providing the spring 224, it is ensured that the probe 221 and the upper surface of the controller 100 are always in abutment during the test.

[0029] Insulating sleeves are provided at intervals within the test unit 220 to prevent high voltage electricity from being transmitted to the support arm 210 through the probe 221. This design can effectively improve the safety of the device and reduce the risk of electric shock to operators.

[0030] In other embodiments of this application, refer to Figure 2-Figure 4As shown, an indicator light 230 is provided on the support arm 210. In a specific implementation, the support arm 210 is further provided with an indicator light 230 and a control module that are interconnected, and a sensor that is electrically connected to the indicator light 230 and the control module is provided at the end of the probe 221. The control module may include a control power supply 240 provided on the support arm 210, and a switch provided on the support arm 210, or a remote control unit is used. When the probe 221 contacts the upper surface of the controller 100, the sensor transmits a signal, the control module issues a command, and the indicator light 230 lights up. At this time, the control module issues another command to electrically connect the probe 221 to the test voltage, thereby further improving the safety of the device and the consistency of the test structure.

[0031] In other embodiments of this application, refer to Figures 1 to 4 The base plate 110 is also provided with a second limiting unit 111. The second limiting unit 111 is used to limit the position of the controller 100 on the base plate 110, preventing the controller 100 from moving during the test. The second limiting unit 111 further secures the controller 100, thereby improving the accuracy and consistency of the test.
