Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to an anesthesia monitoring and control device. Background Art

[0002] When performing orthopedic surgery on the arm, local regional anesthesia is usually used. Anesthesia affects the central nervous system through drugs, causing the patient to temporarily lose perception and consciousness, thereby ensuring the smooth progress of the operation. Monitoring during anesthesia refers to the continuous monitoring and evaluation of the patient's vital signs, respiratory circulation and other important indicators during the anesthesia process. Changes in these data can reflect the effect of anesthetic drugs and the patient's physical condition. When the patient is in a state of deep anesthesia, symptoms such as loss of consciousness and muscle relaxation may occur; while superficial anesthesia may cause the patient to experience pain, discomfort and other reactions. In order to maintain the patient's anesthesia effect, the anesthesiologist needs to continuously add anesthetics according to the progress of the operation and the patient's response to keep the patient in a stable state of anesthesia.

[0003] Existing anesthesia detection and control devices usually use professional equipment to record the patient's physiological parameters in real time, such as heart rate, blood pressure, blood oxygen saturation, end-tidal carbon dioxide concentration, etc. However, the change of heart rate in the heart rate monitoring device may lag behind the change of the patient's actual physiological state, and the reaction of anesthetic drugs may affect the accuracy of the heart rate, resulting in deviations in the monitoring results.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] See also Figures 1 to 10 ,The present invention provides a technical solution: an anesthesia monitoring and control device, comprising: a fixing pad 001;

[0040] Also includes:

[0041] A first traction wheel 002, which is disposed above the fixing pad 001 and is used to effectively pull the patient's fingers;

[0042] A traction adjustment component 003, which is disposed inside the first traction wheel 002 and is used to adjust according to the length of the patient's finger;

[0043] The tightening wheel 004 is disposed below the traction seat 220 and is used to assist the traction assembly so that the patient's fingers can be tightened;

[0044] Detection wheel 005, which is arranged behind the take-up wheel 004 and is used to detect the state of the first traction wheel 002;

[0045] The traction detection component 006 is arranged inside the detection wheel 005. The traction detection component 006 is used to detect the patient's finger dynamics to determine the patient's anesthesia status.

[0046] Among them, after the medical staff performs regional tissue anesthesia on the patient's arm, they place the patient's arm on the fixing pad 001, and adjust the position of the fixing pad 001 according to the position of the patient's arm. Then, the staff tightens the patient's four fingers except the thumb through the first traction rope 210, and makes adaptive adjustments according to the length and bending state of the patient's fingers. When the orthopedic operation time is long, the effect of the anesthetic drug will weaken over time, or the patient will react weakly to the anesthetic drug, so that the patient begins to feel pain or discomfort in the arm, and the direct reaction finger will curl up towards the palm, so that the traction detection component 006 will immediately detect the finger dynamics and determine whether the patient is in deep anesthesia, so as to monitor the patient's anesthesia state in real time during the orthopedic operation.

[0047] The bottom end of the fixing pad 001 is slidably connected to a positioning seat 110 , the front end of the positioning seat 110 is slidably connected to a fixing rail 120 , and the sides of the positioning seat 110 and the fixing rail 120 are both provided with mounting screws 130 .

[0048] Among them, the fixed rail 120 is fixed to the operating table, and the medical staff can adjust the horizontal and vertical positions of the fixed pad 001 according to the positioning seat 110, so as to facilitate the first traction wheel 002 to be close to the patient's fingers and facilitate the first traction rope 210 to restrain the fingers. After adjusting the position of the fixed pad 001, the installation screw 130 can be respectively penetrated into the fixed rail 120 and the positioning seat 110 to fix the position of the fixed pad 001.

[0049] Four first traction wheels 002 are provided, and the front ends of the four first traction wheels 002 are fixedly connected to the first traction rope 210, the outer wall of the first traction wheel 002 is rotatably connected to the traction seat 220, the traction seat 220 is fixedly connected to the fixed pad 001, the interior of the first traction wheel 002 is movably connected to the second traction wheel 230, and one side of the second traction wheel 230 is fixedly connected to the second traction rope 240.

[0050] The traction adjustment assembly 003 includes a movable wheel 301, the outer wall of the movable wheel 301 is fixedly connected to a sliding seat 302, the interior of the sliding seat 302 is slidably connected to a positioning block 303, the top of the positioning block 303 is inclined, the top of the positioning block 303 is meshingly connected to a positioning ring 304, the positioning ring 304 is fixedly connected to the first traction wheel 002, the movable wheel 301 is fixedly connected to the second traction wheel 230, the bottom end of the positioning block 303 is fixedly connected to a return spring 305, the bottom end of the return spring 305 is fixedly connected to a fixing rod 306, the fixing rod 306 is fixedly connected to the movable wheel 301, the fixing rod 306 is rotatably connected to the traction seat 220, a coil spring 307 is installed inside the fixing rod 306, and the coil spring 307 is fixedly connected to the traction seat 220.

[0051] An adjustment groove 310 is formed on the outer wall of the traction seat 220 . An adjustment block 320 is disposed inside the adjustment groove 310 . The adjustment block 320 is fixedly connected to the positioning block 303 .

[0052] The first traction rope 210 is used to traction the patient's finger. The medical staff can press the adjustment block 320 downward, so that the adjustment block 320 drives the positioning block 303 to slide downward inside the slide seat 302. After the positioning ring 304 loses the connection with the positioning block 303, the medical staff can rotate the first traction wheel 002 to complete the retraction and release of the first traction rope 210 and adjust the length of the first traction rope 210 to adapt to the position of the patient's finger under anesthesia. After the medical staff has adjusted it, they can release the adjustment block 320 and reset the spring 305. Immediately drive the positioning block 303 back to the original position, so that the positioning block 303 is meshed and connected with the positioning ring 304. When the first traction rope 210 is driven by the finger, the second traction rope 240 will be driven at the same time, so that the traction detection component 006 can accurately detect the movement of the first traction rope 210. The medical staff adjusts the positions of the four first traction ropes 210 one by one to make the monitoring result of the device more accurate. At the same time, during the adjustment process, the second traction rope 240 may not be driven by the first traction rope 210, so as to avoid affecting the detection result of the traction detection component 006;

[0053] Furthermore, after the first traction rope 210 is adjusted, the coil spring 307 will drive the second traction wheel 230 back to its original position to prevent the second traction wheel 230 from being affected when the medical staff adjusts the first traction wheel 002, thereby affecting the monitoring result of the traction detection component 006.

[0054] There are four tightening wheels 004, and the four tightening wheels 004 correspond to the positions of the four first traction wheels 002 one by one. The tightening wheel 004 is slidingly connected to the second traction rope 240, and the other end of the second traction rope 240 is fixedly connected to the detection wheel 005. The outer wall of the detection wheel 005 is rotatably connected to the fixed shell 330, and a tightening spring 340 is arranged between the fixed shell 330 and the detection wheel 005.

[0055] The tightening wheel 004 can tighten the second traction rope 240 to ensure that the second traction rope 240 is in a tensioned state;

[0056] The traction detection component 006 includes a locking rod 601, a locking groove 602 is provided at the bottom end of the locking rod 601, a movable spring 603 is arranged inside the locking groove 602, a locking block 604 is fixedly connected to the bottom end of the movable spring 603, a first connecting rod 605 is arranged at the bottom end of the locking block 604, the first connecting rod 605 is movably connected to the fixed shell 330, the bottom end of the first connecting rod 605 is movably connected to the detection wheel 005, a connecting rod 606 is fixedly connected to the outer wall of the locking rod 601, a baffle 607 is fixedly connected to the end of the connecting rod 606, and a pressure sensor 608 is arranged below the baffle 607

[0057] The top end of the detection wheel 005 is movably connected to a second connecting rod, and the other end of the second connecting rod is rotatably connected to the locking rod 601 .

[0058] When the anesthesia effect of the patient weakens, the patient's fingers will curl inward, thereby pulling the second traction rope 240 through the first traction rope 210. During the pulling process of the second traction rope 240, the detection wheel 005 rotates inside the fixed shell 330, and the first connecting rod 605 movably connected to the detection wheel 005 will move up and at the same time press against the locking block 604, so that the locking block 604 is retracted into the locking groove 602, and the connecting rod 606 can be movable. Since the second connecting rod is respectively connected to the detection wheel 005 and the locking rod 601, after the locking rod 601 can move, the detection wheel 005 drives the locking rod 601 to rotate inside the fixed shell 330 through the second connecting rod, and the locking rod 601 will drive the baffle 607 to rotate synchronously when rotating, and the baffle 607 will press the pressure sensor 608, and the patient will be given additional anesthetics, so that the patient can be in a deep anesthesia state during orthopedic surgery;

[0059] At the same time, when the locking blocks 604 inside the four fixed shells 330 are all retracted into the locking grooves 602, the connecting rod 606 and the baffle 607 will move. When all four fingers are curled up, it indicates that the patient's anesthesia effect is weakened, which prevents the medical staff from misjudging the traction component due to excessive surgical movements causing the arms to shake due to knocking movements.

[0060] Embodiment 2

[0061] like Figure 11-12 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that an injection tube 710 is fixedly connected to one side of the fixed pad 001, the bottom end of the injection tube 710 is connected to the injection needle 720, a dust cover 730 is provided at the top end of the injection tube 710, and an injection assembly 007 is provided inside the dust cover 730.

[0062] The injection assembly 007 includes an injection screw 701, which passes through a dust cover 730. The bottom end of the injection screw 701 is fixedly connected to a piston 702. Positioning grooves 703 are provided on both sides of the injection screw 701. An engaging block 704 is slidably connected inside the positioning groove 703. The engaging block 704 is fixedly connected to the dust cover 730. The outer wall of the injection screw 701 is threadedly connected to a first bevel gear 705. The side of the first bevel gear 705 is meshedly connected to a second bevel gear 706. A motor 707 is installed at the rear end of the second bevel gear 706.

[0063] Among them, the medical staff inserts the injection needle 720 into the patient's arm to perform regional tissue anesthesia. An appropriate amount of anesthetic solution is placed in the injection tube 710. When the pressure sensor 608 senses the pressure, it will immediately start the motor 707. The motor 707 drives the first bevel gear 705 to drive the second bevel gear 706 to rotate. Since the engaging block 704 limits the injection screw 701, when the second bevel gear 706 rotates, it will drive the injection screw 701 to move downward, so that the piston 702 injects the anesthetic solution in the injection tube 710 into the patient's body, so that the patient's arm can maintain a deep anesthesia state.
