Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an anesthesia depth monitoring device based on electroencephalography (EEG). Background Technology

[0002] During surgery, the preoperative anesthesia process is extremely important. If the anesthesia dosage is incorrect or the surgical time is not well controlled, it will cause great surgical pain to the patient. If the anesthesia fails, the patient will twitch due to pain, which will seriously affect the surgical process and cause medical accidents. Anesthesia depth monitoring device is a reliable way to objectively monitor the depth of anesthesia. The observation and management of the depth of anesthesia is one of the main tasks during anesthesia. At present, anesthesia is divided into light anesthesia, surgical anesthesia and deep anesthesia in clinical practice. Using electroencephalography (EEG) to detect the depth of anesthesia is one of the recent research directions.

[0003] The existing anesthesia depth monitoring device includes a monitoring body 1, a data box 2 for collecting data, a sensor patch, and two transmission lines 4 of different lengths. The data box 2 is plugged into one end of each of the two transmission lines 4, and the other ends of the two transmission lines 4 are plugged into the monitoring body 1 and the sensor patch, respectively, so as to collect patient data through the sensor patch and transmit it to the monitoring body 1 for display. The length of the transmission line 4 used to connect the patch is much longer than the length of the transmission line 4 used to connect the monitoring body 1. For easy distinction, the longer transmission line 4 is designated as transmission line one 41, and the shorter one is designated as transmission line two 42.

[0004] The device detects the patient's brain waves and consciousness status by using a sensor patch on the patient's body surface. However, the monitoring line cannot be easily stored after use, which makes it inconvenient to quickly transfer the instrument. The monitoring line is also at risk of being lost. Therefore, this invention provides an anesthesia depth monitoring device based on electroencephalography. Summary of the Invention

[0005] The purpose of this invention is to provide an anesthesia depth monitoring device based on electroencephalography (EEG) to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An anesthesia depth monitoring device based on electroencephalography (EEG) includes a monitoring device body and an integrated part extending downward from the bottom of the monitoring device body. A driving structure is fixedly connected inside the integrated part. The driving structure is engaged with a lifting structure. A load-bearing structure is fixedly connected to the lifting structure. The load-bearing structure is slidably connected to the outer wall of the bottom of the integrated part. The driving structure drives the lifting structure to move vertically, thereby driving the load-bearing structure to move vertically. The supporting structure includes a base plate and a supporting plate. The end of the supporting plate near the first transmission line is rotatably connected to the upper side of the base plate. A cable management device is fixedly connected to the upper side of the supporting plate near the second transmission line, so that when the supporting structure rises, the cable management device rotates and automatically stores the first transmission line. The cable management device includes a winding ring fixedly connected to the upper side of the support plate for winding transmission line one, multiple winding rods, multiple limiting plates, and a rotating assembly. The multiple winding rods are distributed in a ring and fixed to the upper side of the winding ring. The multiple limiting plates are distributed in a ring around the outer periphery of the winding ring and fixedly connected to the upper side of the support plate. The inner wall of the limiting plate has a gap from the outer wall of the winding ring to limit the position of transmission line one.

[0007] Preferably, the limiting plate is trumpet-shaped and its height is lower than that of the winding rod. Under the action of the slope of the limiting plate, the transmission line one automatically stacks upward when it is wound. The outer wall of the winding ring has a groove for detachably fixing the end of the transmission line one. The inner wall of the winding ring has a notch. A spring one is fixedly connected to the bottom of the notch. A rotating plate is fixedly connected to the upper side of the spring one. The rotating plate protrudes from the inner wall of the winding ring.

[0008] Preferably, the rotating assembly includes a positioning ring, a driving ring, and a spring. The positioning ring is rotatably connected to the bottom of the integrated part and meshes with the driving structure. The driving ring is axially slidably connected to the inner wall of the positioning ring. The spring is located in the cavity formed by the driving ring and the positioning ring and abuts against the driving ring.

[0009] Preferably, the drive ring is positioned at a distance from the top of the winding rod, allowing the data box to be rotated out from the bottom of the integration section by rotating the support plate, making it easy to retrieve the data box; the end of the drive ring near the support plate is rotatably connected to a unidirectional rotating drive plate.

[0010] Preferably, the diameter formed by the side of the driving plate away from the driving ring is larger than the inner diameter formed by the side of the rotating plate away from the inner wall of the winding ring, and there is a gap between the driving plate and the inner wall of the winding ring; the driving ring rotates into the winding ring, the driving plate contacts the rotating plate, and drives the winding ring to rotate, thereby winding the wire. When the driving ring leaves the winding ring, the driving ring rotates in the opposite direction, and after the driving plate contacts the rotating plate, the driving plate rotates and fits against the outer wall of the driving ring.

[0011] Preferably, a protective part is fixedly connected to the upper side of the support plate for embedding the data box to keep it fixed; the display side of the monitor body is set as the front, and the side away from the display side is set as the back.

[0012] Preferably, the integrated part has a second groove near the bottom of the monitor body; the drive structure includes a motor, a rotating shaft, a central shaft and a connecting ring connected to the bottom of the integrated part. The rotating shaft is rotatably connected inside the second groove and fixedly connected to the motor, while protruding from the back of the monitor body. One end of the central shaft is engaged with the rotating shaft, and the other end passes through the integrated part and is engaged with the connecting ring. At the same time, the connecting ring is engaged with the positioning ring, thereby driving the positioning ring to rotate.

[0013] Preferably, the lifting structure includes a lifting shaft, a pair of lifting rods, and four sliding rods. The top end of the lifting shaft is rotatably connected to a fixed part extending from the back of the monitor body, the middle part is engaged with a rotating shaft, and the bottom end is threaded with a threaded ring. One end of the lifting rod is fixedly connected to the threaded ring, and the other end is fixedly connected to the sliding rod. The bottom ends of the four sliding rods are respectively fixedly connected to the two ends of the base plate and slidably connected to the monitor body.

[0014] Preferably, the upper part of the lifting rod is fixedly connected to a storage groove for storing the power cord connecting the monitor body and the power supply; when the rotating shaft rotates, it drives the lifting shaft to rotate, causing the threaded ring to drive the lifting rod to move axially, thereby driving the sliding rod to slide up and down, and causing the base plate and the sliding rod to move up and down.

[0015] Preferably, the front and back sides of the monitor body are provided with grooves 3, and a support rod is rotatably connected in the grooves 3. When the monitor body is tilted, the support rod on the corresponding side rotates out of the groove 3 to abut against the support surface, thereby supporting the monitor body and preventing damage to the monitor body.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention has a simple structure and is easy to operate. By integrating the part extending from the bottom of the monitor body with the lifting structure, cable management device and bearing structure, it replaces manual cable winding and achieves the effect of automatic cable winding. It also integrates the transmission line, data box and monitor body for easy carrying. It can also avoid the problem of forgetting to bring the transmission line or data box when moving to other places, or being unable to find it due to improper storage. It is also more convenient to carry. The inclined limiting plate, the winding ring, and the winding rod work together to wind the transmission line around the outside of the winding ring and the winding rod. The limiting plate forces the transmission line to gradually accumulate upwards as it winds around the inner wall of the limiting plate, thus accommodating longer transmission lines. At the same time, the winding process and the rising of the supporting structure are carried out simultaneously. The transmission line and data box are placed inside the bottom of the integration section, which improves the storage efficiency and prevents the loss of the transmission line or storage box. The lifting structure and drive structure are located on the back of the monitor body and inside the integration section, respectively. When in use, the sliding rod is also located on the lower side of the front, away from the display screen, so that the operator will not affect the viewing of the display screen when using it.

[0019] Example 1:

[0020] Please see Figure 1-6 The present invention provides a technical solution: such as Figure 1-2 As shown, an anesthesia depth monitoring device based on electroencephalography (EEG) includes a monitoring body 1 and an integrated section 11 extending downward from the bottom of the monitoring body 1. A drive structure 5 is fixedly connected inside the integrated section 11. The drive structure 5 is engaged with a lifting structure 6. A support structure 7 is fixedly connected to the lifting structure 6. The support structure 7 is slidably connected to the outer wall of the bottom of the integrated section 11. The drive structure 5 drives the lifting structure 6 to move vertically, thereby driving the support structure 7 to move vertically. The length of the transmission line 4 used to connect the patch is much longer than the length of the transmission line 4 used to connect the monitoring body 1. The display side of the monitoring body 1 is the front, and the side away from the display side is the back. The supporting structure 7 includes a base plate 71 and a supporting plate 72. One end of the supporting plate 72 near the second transmission line 42 is rotatably connected to the upper side of the base plate 71. A protective part 721 is fixedly connected to the upper side of the supporting plate 72 for embedding the data box 2 to keep it fixed. A cable management device 73 is fixedly connected to the upper side of the supporting plate 72 near the second transmission line 42, so that when the supporting structure 7 rises, the cable management device 73 rotates and automatically collects the first transmission line 41, thereby replacing manual cable collection.

[0021] like Figure 2-4As shown, the cable management device 73 includes a winding ring 731 fixedly connected to the upper side of the support plate 72 for winding the transmission line 41, multiple winding rods 732, multiple limiting plates 733, and a rotating assembly 734. The multiple winding rods 732 are arranged in a ring and fixed to the upper side of the winding ring 731. The multiple limiting plates 733 are arranged in a ring around the outer periphery of the winding ring 731 and fixedly connected to the upper side of the support plate 72. The inner wall of the limiting plate 733 has a certain gap from the outer wall of the winding ring 731 to limit the position of the transmission line 41. The limiting plates 733 are trumpet-shaped, with a vertical height lower than the winding rods 732. The diameter of the ring formed by the multiple limiting plates 733 gradually increases from bottom to top. When the winding ring 731 drives the transmission line 41 to rotate, the transmission line 41 is wound around the winding ring 731. The outer wall of the winding ring 731 forms the first winding layer, and gradually expands to the inner wall of the limiting plate 733. Under the action of the inclined slope of the limiting plate 733, the remaining transmission line 41 is located on the upper layer of the first transmission line 41. Similarly, when the height of the winding ring 731 is insufficient, it can continue to wind upward to the outer wall of the winding rod 732 to avoid all the transmission lines 41 piling up at the bottom layer, and at the same time, it can wind a longer transmission line 41. The outer wall of the winding ring 731 has a groove 7311 for detachably fixing the end of the transmission line 41. The inner wall of the winding ring 731 has a notch, and a spring 7312 is fixedly connected to the bottom of the notch. A rotating plate 7313 is fixedly connected to the upper side of the spring 7312. The rotating plate 7313 protrudes from the inner wall of the winding ring 731. The rotating assembly 734 includes a positioning ring 741, a driving ring 742, and a spring 743. The positioning ring 741 is rotatably connected to the bottom of the integrated part 11 and meshes with the driving structure 5. The driving ring 742 is axially slidably connected to the inner wall of the positioning ring 741. The spring 743 is located in the cavity formed by the driving ring 742 and the positioning ring 741 and abuts against the driving ring 742. In its natural state, the driving ring 742 is a certain distance away from the top of the winding rod 732, so that the data box 2 can be rotated out from the bottom of the integrated part 11 by rotating the support plate 72, making it easy to pick up the data box 2. A driving plate 7421 is rotatably connected to the end of the driving ring 742 near the support plate 72. The driving plate 7421 can rotate in one direction. The straight line formed by the side of the driving plate 7421 away from the driving ring 742 is... The diameter is larger than the inner diameter formed on the side of the rotating plate 7313 away from the inner wall of the winding ring 731, and there is a certain gap between the rotating plate 7313 and the inner wall of the winding ring 731. When the carrying plate 72 drives the wire management device 73 to move towards the integration part 11, the driving ring 742 will gradually rotate and enter the inner wall of the winding ring 731. As the driving ring 742 rotates, the driving plate 7421 contacts the rotating plate 7313 and begins to drive the winding ring 731 to rotate, thereby winding the wire. When the carrying plate 72 drives the wire management device 73 to move away from the integration part 11, the driving plate 7421 contacts the rotating plate 7313, drives the plate 7421 to rotate and fits against the outer wall of the driving ring 742, thereby causing the driving ring 742 to disengage from the winding ring 731 and not drive the winding ring 731 to rotate.

[0022] like Figure 2 , 5 As shown in Figure 6, the drive structure 5 includes a motor, a rotating shaft 51, a central shaft 52, and a connecting ring 53. The integrated part 11 has a groove 2 near the bottom of the monitor body 1. The rotating shaft 51 is rotatably connected to the inside of the groove 2 and fixedly connected to the motor. It also protrudes from the back of the monitor body 1. One end of the central shaft 52 is engaged with the rotating shaft 51, and the other end passes through the integrated part 11 and is engaged with the connecting ring 53. At the same time, the connecting ring 53 is engaged with the positioning ring 741, thereby driving the positioning ring 741 to rotate. The connecting ring 53 is rotatably connected to the bottom of the integrated part 11. The motor is linearly connected to an up switch and a down switch. The switches are installed on the top of the monitor body 1 and the motor is started or stopped by pressing.

[0023] like Figure 5-6As shown, the lifting structure 6 includes a lifting shaft 61, a pair of lifting rods 62, and four sliding rods 63. The top end of the lifting shaft 61 is rotatably connected to a fixed part extending from the back of the monitor body 1, the middle part is engaged with the rotating shaft 51, and the bottom end is threaded with a threaded ring. One end of the lifting rod 62 is fixedly connected to the threaded ring, and the other end is fixedly connected to the sliding rod 63. The bottom ends of the four sliding rods 63 are respectively fixedly connected to the two ends of the base plate 71 and are slidably connected to the monitor body 1. The rotation of the rotating shaft 51 drives the lifting shaft 61 to rotate, thereby causing the threaded ring to drive the lifting rod 62 to move axially, thereby causing the sliding rods 63 to slide up and down, and causing the base plate 71 and the sliding rods 63 to move up and down. The upper part of the lifting rod 62 is fixedly connected to a storage groove, which can be used to store the power cord of the monitor body 1 and the power supply. The bottom of the integration section 11 has an irregular side groove 111 to match the shape of the transmission line 4, protection section 721, data box 4, drive structure 5 and cable management device 7 on the support plate 72, so as to ensure the normal operation of the transmission line 4.

[0024] Working principle: From the time the monitor body 1 is closed until it is in use, the operator takes out the power cord from the storage slot, connects it to the power supply, and then presses the rise switch to start the motor. The motor drives the rotating shaft 51 to rotate, which in turn drives the lifting shaft 61 to rotate. This causes the lifting rod 62 to move the sliding rod 63 and the base plate 71 downward, thereby pushing the monitor body 1 upward in the opposite direction. At the same time, the rotation of the rotating shaft 51 drives the positioning ring 741 to rotate through the transmission of the central shaft 52 and the connecting ring 53. The positioning ring 741 drives the drive ring 742 to rotate. When the driving plate 7421 contacts the rotating plate 7313, the driving plate 7421 rotates and fits against the outer wall of the drive ring 742. As it rotates, it gradually rotates out from inside the winding ring 731. Then, the operator stops pressing the rise switch, the motor is turned off, the second transmission line 42 is taken out from one side and connected to the monitor body 1, the support plate 72 is rotated out, and the first transmission line 41 wrapped in the limiting plate 733 is taken out and connected to the sensing patch. When retracted, transmission line 41 is disconnected from the sensing patch, and its end is inserted into groove 7311. Then, the carrier plate 72 is rotated to the underside of the integrated part 11, the descent switch is pressed, and the motor is started. The motor rotates in reverse, causing the lifting rod 62 to move the sliding rod 63 and the base plate 71 upward, thereby pushing the monitoring instrument body 1 downward in the opposite direction. At the same time, the drive ring 742 gradually enters the winding ring 731. As the drive ring 742 rotates, the driving plate 7421 disengages from the attached state and contacts the rotating plate 7313, thereby driving the rotating plate 7313 and the winding ring 731 to rotate. The rotation of the winding ring 731 causes transmission line 41 to gradually wind around the outside of the winding ring 731. Under the action of the slope of the limiting plate 733, transmission line 41 continues to... Continue winding upwards; when transmission line 1 41 is wound, drive plate 7421 extends into the bottom of winding ring 731 and disengages from rotating plate 7313, no longer driving rotating plate 7313 to rotate. As the support plate 72 continues to rise, drive ring 742 begins to compress spring 743 (conversely, when in use, spring 743 will also return to the non-compressed state). When the support of sliding plate 63 on the monitor body 1 switches to the support of the bottom of integrated part 11 on the monitor body 1, stop pressing and turn off the motor; transmission line 2 42 can be unplugged or not as needed. If it needs to be unplugged, it needs to be unplugged before the motor starts after the support plate 72 rotates to the underside of integrated part 11, and then placed under integrated part 11; finally, unplug the power cord and place it in the storage slot.

[0025] It should be noted that during the winding process, when the drive ring 742 enters the winding ring 731, there is a contact between the end of the drive plate 7421 and the end of the rotating plate 7313. The rotating plate 7313 is pressed downward by the contact, which compresses the spring 7312, causing the rotating plate 7313 to be misaligned with the drive plate 7421. The contact disappears, the rotating plate 7313 rises, contacts the drive plate 7421 that has rotated one revolution, and rotates with the drive plate 7421.

[0026] Example 2:

[0027] Based on Example 1, such as Figure 1 , Figure 5 As shown, the monitor body 1 has grooves 3 on both the front and back sides. A support rod 12 is rotatably connected in the groove 3. When the sliding rod 63 is fully located on the outer periphery of the integrated part 11, the sliding rod 63 covers the bottom of the support rod 12 to prevent the support rod 12 from rotating out. When the monitor body 1 is in use, the sliding rod 63 slides downward, allowing the support rod 12 to rotate freely out of the groove 3. In case of an accident that causes the monitor body 1 to tilt forward or backward, the corresponding support rod 12 will rotate out first to contact the support surface to support the monitor body 1 and prevent damage to the monitor body 1.
