Description

Technical Field

[0001] The utility model relates to the technical field of pain perception monitors, in particular to a pain perception monitor and a connector. Background Art

[0002] The Pain and Nociception Monitor is intended for use in medical institutions. It is suitable for continuous, real-time monitoring of pain and nociception in patients undergoing surgery, anesthesia, or critical illness, providing a reference for clinical diagnosis and treatment. The monitor displays information such as sympathetic nervous system activity (SAS), vagal activity (VAS), stress response index (SRI), heart rate (HR), real-time heart rate deceleration (DCr), a real-time scatter plot, and a single-lead ECG waveform or pulse waveform.

[0003] In the existing technology, the connector is directly plugged into the monitor, and the connection method does not have a release structure. The connector can easily fall off the monitor due to accidental touch, which makes the stability and reliability of the monitor body low during operation. In addition, the sealing performance between the connector and the monitor body is poor, and the waterproof performance is insufficient. Therefore, we have launched a pain perception monitor and connector. Utility Model Content

[0004] The purpose of the present utility model is to provide a pain perception monitor and connector, which can prevent the connector from falling off when the monitor body is working, improve the stability and reliability of the monitor body when working, and improve the sealing performance between the connector and the monitor body, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A connector includes an electrode sheet, an electrode wire and a plug, wherein the electrode sheet and the plug are respectively fixedly arranged at the two ends of the electrode wire, a metal contact is provided at the other end of the plug, strip grooves are provided on both sides of the plug, a fixing ring is slidingly provided on the outside of the metal contact, the fixing ring is slidably connected to the outer wall of the plug, a locking mechanism is provided between the strip groove and the fixing ring, and the fixing ring is fixedly connected to the monitor body at the socket.

[0007] Furthermore, the locking mechanism includes two rotating plates, and the ends of the two rotating plates away from the metal contacts are rotatably connected to the strip grooves through a rotating shaft. The side walls of the rotating plates are provided with strip holes, and a sliding rod is provided for sliding in the strip holes. One end of the sliding rod is fixedly connected to the strip groove, and the other end of the sliding rod is fixedly provided with a round block. The sliding rod wall is movably provided with a spring at the position between the rotating plate and the strip groove. The rotating plate is fixedly provided with a wedge block at one end away from the rotating shaft, and the side wall of the fixing ring is provided with an annular groove that cooperates with the wedge block.

[0008] Furthermore, the diameter of the round block is greater than the width of the strip hole.

[0009] Furthermore, the spring is always in a compressed state.

[0010] Furthermore, a sealing ring is fixedly provided on one side of the fixing ring close to the plug.

[0011] Furthermore, the sealing ring is a high-temperature resistant rubber ring.

[0012] A pain perception monitor comprises a monitor body, wherein one side of the monitor body is provided with a touch display screen, and the other side of the monitor body is provided with a plurality of sockets matching with metal contacts of a plug.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The pain perception monitor and connector are equipped with a touch screen, a monitor body, an electrode line, an electrode sheet, a fixing ring, a plug, a spring, a rotating plate, a slide bar, a round block, a wedge block, a sealing ring, a jack, and a metal contact. The plug is inserted into the fixing ring, and the metal contact at one end of the plug is inserted into the jack. The fixing ring pushes the rotating plate to rotate through the inclined surface of the wedge block. The rotating plate squeezes the spring while rotating, and the slide bar slides in the strip hole. When the wedge block is engaged with the annular groove, the spring pushes the rotating plate to rotate and drives the wedge block to be engaged in the annular groove. At this time, the connector is connected to the monitor body, which can prevent the connector from falling off when the monitor body is working, improves the stability and reliability of the monitor body when working, and improves the sealing performance between the connector and the monitor body. The two rotating plates are pushed, and the rotating plates drive the wedge block to leave the annular groove, so that the plug can be taken out of the fixing ring. BRIEF DESCRIPTION OF THE DRAWINGS
