Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to an electrode consumable insertion detection device. Background Technology
[0002] In the use of medical devices, electrode consumables are often required for various medical procedures, such as electrical stimulation therapy. To ensure the normal operation of the device and the safety and effectiveness of medical procedures, accurately detecting whether the electrode consumables are correctly inserted into the device interface is crucial. Traditional detection methods may suffer from inaccuracies and low reliability, failing to meet the increasingly demanding performance requirements of medical devices. Below are some traditional methods for detecting electrode insertion:
[0003] Manual visual inspection: Operators determine the insertion status by directly observing whether the electrode is inserted into the correct position on the interface. This inspection method is highly subjective and prone to misjudgment; it cannot be automated and is inefficient; for interfaces with complex internal structures or those difficult to observe directly, it cannot accurately determine the insertion status.
[0004] Mechanical contact testing: This method determines whether the electrode is properly inserted by measuring the physical changes in the mechanical structure, such as displacement and pressure, caused by the insertion of the electrode consumable. For example, a microswitch is installed at the interface; when the electrode is inserted and pushes the switch, the switch state changes, thus sending an insertion signal. However, mechanical parts are prone to wear, and long-term use may lead to a decrease in detection accuracy; it also has certain requirements for insertion force and angle, and improper insertion may result in inaccurate detection; furthermore, it cannot detect finer details such as whether the electrode has become loose after insertion.
[0005] Electrical detection: This method relies on the electrical circuit formed after electrode insertion or changes in electrical parameters for detection. For example, electrode pins are placed at the interface. When a disposable electrode is inserted, the pins contact the corresponding electrode on the electrode, completing the circuit. Changes in electrical parameters such as current and resistance are then detected to determine the insertion status. Electrical detection requires high conductivity and contact stability from the electrodes. Oxidation, contamination, or poor contact on the electrode surface can lead to detection failure.
[0006] Therefore, accurately determining whether electrode consumables are correctly inserted into the device interface is a focus of attention for those skilled in the art. Utility Model Content
[0007] The purpose of this invention is to provide an electrode consumable insertion detection device that can accurately determine whether the electrode consumable is correctly inserted into the device interface.
[0008] To achieve the above objectives, this utility model provides an electrode consumable insertion positioning detection device, comprising:
[0009] Multiple consumable interfaces are provided. After the electrode consumable is inserted into the corresponding consumable interface, it can be connected to the device.
[0010] Multiple sets of infrared receivers and infrared transmitters are arranged opposite each other on the outer periphery of the corresponding consumable interface, and are arranged obliquely.
[0011] The consumable interface has a protruding annular outer edge, and two opposing slots are provided on the annular outer edge, which serve as infrared light paths.
[0012] When the electrode consumable is inserted into the consumable interface, the electrode consumable will block the infrared transmission path between the infrared emitting tube and the infrared receiving tube, so that the infrared light received by the infrared receiving tube is blocked or weakened.
[0013] A control unit is connected to the infrared receiver tube; the control unit is preset with an infrared receiving state when the electrode consumable is not inserted; if the current state is reversed compared with the state when the electrode consumable is not inserted, it is determined that the electrode consumable has been inserted.
[0014] A status indicator light, connected to the control unit, is located near each of the consumable interfaces and is used to indicate the current connection status of the electrode consumables in the consumable interface based on the judgment result of the control unit.
[0015] In an optional embodiment, the positioning detection device includes a panel cover, a circuit board, and a panel bottom shell arranged sequentially from top to bottom;
[0016] The upper cover of the panel has holes for consumable interfaces and holes for status indicator lights;
[0017] The circuit board has through holes corresponding to the consumable interface holes, status indicator lights corresponding to the status indicator light holes, and infrared receiver tubes and infrared emitters tubes arranged opposite to each other.
[0018] The bottom shell of the panel is provided with a consumable interface corresponding to the consumable interface hole.
[0019] In optional solutions, the consumable interface has multiple types to accommodate different types of electrode consumables.
[0020] In an optional configuration, when an electrode consumable experiences a connection abnormality, causing intermittent blockage of the infrared transmission path, the control unit controls the status indicator light to issue an alarm signal.
[0021] The beneficial effects of this utility model are as follows:
[0022] When the electrode consumable is inserted into the consumable interface, it blocks the infrared transmission path between the infrared emitting tube and the infrared receiving tube, thus blocking or weakening the infrared light received by the infrared receiving tube. By comparing the current state with the state when the electrode consumable is not inserted, it is possible to accurately determine whether the electrode consumable is inserted into the interface. The angled design of the infrared component effectively prevents foreign objects from falling in and blocking the light path, as well as mutual interference between adjacent interface channels.

[0033] Example 1
[0034] Reference Figures 1 to 3 This embodiment provides an electrode consumable insertion positioning detection device 1, comprising:
[0035] Multiple consumable interfaces 9 are provided. After the electrode consumable 2 is inserted into the corresponding consumable interface 9, it is connected to the device.
[0036] Multiple sets of infrared receiver tubes 8 and infrared emitter tubes 10 are arranged opposite each other on the outer periphery of the corresponding consumable interface 9, and are arranged obliquely.
[0037] The consumable interface 9 has a protruding annular outer edge on its outer periphery, and two opposing slots 7 are provided on the annular outer edge, which serve as infrared light paths.
[0038] When electrode consumable 2 is inserted into consumable interface 9, electrode consumable 2 will block the infrared transmission path between infrared emitting tube 10 and infrared receiving tube 8, so that the infrared light received by infrared receiving tube 8 is blocked or weakened.
[0039] The control unit is connected to the infrared receiver tube 8; the control unit is preset with an infrared receiving state when the electrode consumable is not inserted; if the current state is reversed compared with the state when the electrode consumable is not inserted, it is determined that the electrode consumable has been inserted.
[0040] Status indicator 6, connected to the control unit, is located near each of the consumable interfaces 9 and is used to indicate the current connection status of the electrode consumable 2 in the consumable interface 9 according to the judgment result of the control unit.
[0041] Specifically, in this embodiment, the consumable interface 9 has multiple types to accommodate different types of electrode consumables 2. Various types of electrode consumables 2 connect to the device through the consumable interface 9. A status indicator light 6 is designed directly above the consumable interface to indicate the connection status of the electrode consumable 2 to the user. The infrared receiver 8 and infrared transmitter 10 are angled, and the connection line of the slot 7 is also angled, such as at 45°. This serves two purposes: first, to prevent foreign objects from falling into the bottom of the interface and blocking the infrared path; and second, to prevent mutual interference between adjacent consumable interface channels in the horizontal slot.
[0042] In this embodiment, the positioning detection device includes a panel cover 3, a circuit board 4, and a panel bottom shell 5 arranged sequentially from top to bottom. The panel cover 3 has a consumable interface hole and a status indicator hole. The circuit board 4 has a through hole corresponding to the consumable interface hole, a status indicator 6 corresponding to the status indicator hole, and an infrared receiver 8 and an infrared emitter 10 arranged opposite to each other. The panel bottom shell 5 has a consumable interface 9 corresponding to the consumable interface hole. The electrode consumable 2 can be inserted into the consumable interface 9 through the consumable interface hole at the front to connect with the device.
[0043] When the device is started, the infrared emitting tube 10 continuously emits infrared light using a specific carrier pulse. When the electrode consumable 2 is not inserted into the consumable interface 9, the infrared light is successfully received by the infrared receiving tube 8. The infrared receiving tube 8 decodes the received specific carrier infrared signal and transmits the status to the control unit. The control unit is preset with the infrared reception status when the consumable is not inserted.
[0044] When electrode consumable 2 is inserted into consumable interface 9, it blocks the infrared transmission path between infrared emitting tube 10 and infrared receiving tube 8, causing the infrared light received by infrared receiving tube 8 to be blocked or significantly weakened. Infrared receiving tube 8 decodes the changed signal and transmits the new state to the control unit. The control unit compares and analyzes the received state change. If the state is reversed compared to the state when the consumable is not inserted, it is determined that electrode consumable 2 has been inserted. At this time, the control unit can activate the relevant functions of the medical device according to the device's operating program, such as performing a discharge operation according to the set pulse parameters.
[0045] If, during equipment operation, the infrared transmission path is intermittently blocked due to loosening of the electrode consumable 2 or other abnormalities, the signal strength received by the infrared receiver tube 8 will fluctuate. Upon detecting this abnormal signal change, the control unit will immediately control the status indicator 6 to issue an alarm signal and stop the equipment output. Alternatively, it may flash the indicator light to remind the operator to promptly check the insertion status of the electrode consumable 2 and take appropriate action, ensuring the safety and normal operation of the medical procedure.
[0046] This embodiment has the following characteristics:
[0047] Multifunctional integration: This positioning detection device integrates an interface for connecting electrode consumables to the equipment, as well as a status indicator light for displaying the connection status of electrode consumables. This allows users to intuitively understand the connection status of electrode consumables and integrates connection and status prompt functions.
[0048] The structure is rationally layered: it consists of a top cover, a circuit board, and a bottom cover. The top cover has dedicated consumable interface holes and status indicator holes to ensure connection and display; the circuit board carries the electronic components that realize the infrared detection function; the bottom cover serves as the circuit board mounting base and is designed with an infrared light path to ensure the optical path for infrared detection. Each part has a clear division of labor and works together in a coordinated manner.
[0049] Special angle installation: The infrared emitting tube and the infrared receiving tube are installed at a 45° angle on both sides of the consumable interface. This angle design avoids the problem of foreign objects falling into the bottom of the interface and blocking the infrared path when the vertical slot is cut. On the other hand, it prevents mutual interference between adjacent interface channels when the horizontal slot is cut. At the same time, it also takes into account the good detection sensitivity under different consumable insertion depths and reduces the offset of the optical path caused by vibration and other factors, effectively improving the detection accuracy and stability.
[0050] Comprehensive coverage of abnormal situations: It can comprehensively monitor a variety of abnormal situations, such as abnormal infrared transmission caused by loose or damaged electrode consumables, as well as abnormalities in the infrared detection system caused by internal circuit failures. It can issue alarm signals with different flashing patterns through status indicator lights for different abnormalities and stop the equipment output, so as to facilitate operators to quickly identify and deal with problems and ensure the safety of medical operations.
[0051] This embodiment has the following beneficial effects:
[0052] Precise insertion status determination:
[0053] Effect: By comparing the current state with the state when the consumable is not inserted, it can accurately determine whether the electrode consumable is inserted into the interface. It can accurately identify whether the electrode consumable is normally inserted, not inserted, or has become loose during insertion. Compared to traditional detection methods (such as simple mechanical contact or simple electrical detection methods, which are easily affected by poor contact, electromagnetic interference, etc., leading to misjudgments), this embodiment greatly improves the accuracy of detection, ensuring that medical devices can perform subsequent operations based on accurate consumable insertion status information, such as discharging according to set parameters, thereby improving the reliability and effectiveness of medical operations.
[0054] Advantages of a stable optical path design:
[0055] The infrared beam transmitter features a unique design with its 45° installation on both sides of the consumable interface. Combined with a carefully designed infrared light path on the bottom of the panel, this effectively prevents foreign objects from obstructing the light path and avoids interference between adjacent interface channels. Furthermore, it maintains stable infrared transmission and reception at different consumable insertion depths and during long-term use, ensuring stable and reliable detection signals. Compared to conventional optical detection methods where the optical path is susceptible to interference from environmental factors (such as dust, debris, or crosstalk between adjacent optical paths), the optical path design in this embodiment offers higher stability, further guaranteeing the accuracy of the detection results. This allows the medical device to consistently and accurately detect consumable insertion even in complex operating environments.
[0056] Comprehensive anomaly monitoring and alarms:
[0057] It can comprehensively monitor a variety of possible anomalies, including loose or damaged electrode consumables and malfunctions in the infrared detection system caused by internal circuit faults. Once an anomaly is detected, the control unit will immediately control the status indicator light to emit alarm signals with different flashing patterns and stop the equipment output. Operators can quickly determine the cause of the anomaly and take appropriate action based on the flashing pattern of the indicator light.
[0058] Traditional manual visual inspection or some simple detection devices often fail to detect these anomalies comprehensively and in a timely manner. This embodiment realizes automated and comprehensive anomaly monitoring and alarm reminders, which greatly reduces the risk of medical accidents caused by abnormal consumable connections and comprehensively protects the safety of equipment and patients during medical operations.
[0059] Intuitive status display:
[0060] A status indicator light is designed directly above the consumable interface, clearly indicating the connection status of the electrode consumables to the user. Whether the connection is normal, the insertion is abnormal, or a malfunction has occurred, the user can obtain relevant information at a glance. Compared to devices without status indicators or with less intuitive indicators, this embodiment allows operators to quickly understand the connection status of the electrode consumables and the device. It eliminates the need for complex operations or additional tests to determine the device status, saving time and improving the convenience and overall efficiency of medical procedures.
[0061] Integrated panel components:
[0062] By integrating consumable interfaces, infrared detection circuit boards, and status indicator lights onto a single panel assembly, the various components are rationally laid out and work together seamlessly. This achieves both a compact device design and ensures efficient collaborative operation of all functions. Compared to some device designs with scattered functional modules and complex connections, the integrated panel assembly in this embodiment makes the overall structure of the device simpler and easier to maintain. It also improves efficiency and reduces costs during production and assembly, and reduces potential malfunctions caused by complex component connections, thereby enhancing the overall stability and reliability of the equipment.
[0063] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
