Description

Technical Field

[0001] This invention belongs to the field of post-oral surgical instruments, specifically relating to an intelligent monitoring device for post-mental surgery. Background Technology

[0002] Chin augmentation surgery is a common oral plastic surgery procedure used to correct the shape of the chin. After the surgery, patients need to have a drainage tube placed in the surgical area to drain blood and fluid from the interstitial spaces. Postoperative pain management is also crucial.

[0003] Currently, postoperative drainage and analgesia are usually performed independently. Traditional drainage uses negative pressure drainage, with a drainage tube inserted into the surgical area and the other end connected to a syringe. This requires manual monitoring by medical staff or the patient, and periodic aspiration. However, manual aspiration is often delayed. If aspiration is not timely, it will lead to fluid accumulation. Fluid accumulation can easily lead to the absorption of fluid by tissue fluid, which can then cause infection. At the same time, a large accumulation of fluid can cause swelling in the surgical area, which can deform and compress the trachea, posing a risk of suffocation.

[0004] Pain relief is administered manually. A catheter is inserted into the surgical area, with a syringe attached to the other end. Medical staff administer the medication manually at regular intervals. Drainage must be stopped before administration, and resumed once the anesthetic is expected to take effect. The administration process is cumbersome, and errors or omissions are easily made when medical staff are busy. Furthermore, the drainage tube is not specifically designed for the chin nerves. There are two nerve trunks in the chin, and conventional catheters can only allow the medication to diffuse freely into the surgical area to the nerve trunks, but cannot deliver it precisely to the nerve trunks, resulting in poor drug targeting.

[0005] Therefore, there is an urgent need to develop an intelligent and automated monitoring device that integrates intelligent drainage and targeted analgesia for mentoplasty. Summary of the Invention

[0006] To address the aforementioned issues, this invention proposes an intelligent monitoring device for post-genioplasty surgery that integrates drug administration and drainage, achieving full automation and integration of the entire process, including automatic drainage, automatic monitoring, and intelligent drug administration. This significantly reduces the workload of medical staff and improves accuracy and comfort.

[0007] The specific solution is as follows: a smart monitoring device for post-genioplasty surgery, comprising a drainage unit, a drug delivery unit, and a control unit, wherein the drainage unit and the drug delivery unit are both connected to the control unit; The drainage unit includes a drainage container, which is connected to an implantation tube and an air suction mechanism to create negative pressure inside the drainage container for drainage. The drug delivery unit and the implantation tube are connected. The implantation tube has independent channels for drainage and drug delivery. The control unit controls the drug delivery unit to deliver anesthetic to the implantation tube. A fluid detector is installed at the implantation site to monitor the outflow of accumulated fluid; The drainage container is equipped with a liquid level monitor and a weight sensor that are connected to the control unit. The liquid level monitor is used to acquire liquid level data, and the weight sensor is used to acquire liquid weight data. The control unit can calculate the continuous time period data variables of liquid level data and weight data, thereby adjusting the delivery volume of anesthetic.

[0008] Preferably, the implantable tube includes a drug delivery chamber and a drainage chamber as independent channels for drainage and drug delivery. The drug delivery chamber and drainage chamber of the implanted tube are integrated into one part and extend to the nerve trunks on both sides. The drug delivery chamber and drainage chamber of the implanted tube outside the body are separated. The drug delivery chamber and the drug delivery unit are connected, and the drainage chamber and the drainage container are connected.

[0009] To avoid having too many tubes implanted in the surgical area, the internal implant is integrated to reduce space occupation, improve the patient's experience, and increase comfort during drainage; while the external implant is separate to facilitate monitoring.

[0010] Preferably, the sidewall of the drainage cavity has several drainage holes, and the outer wall of the drainage cavity has multiple protrusions randomly distributed to support the muscle tissue at the implantation site and prevent it from blocking the drainage holes. To address the issues of uneven drainage and easy blockage by muscles in a single drainage hole, the drainage cavity has multiple drainage holes distributed on the side wall, along with multiple protrusions, forming multiple drainage spaces and achieving simultaneous drainage from multiple points, resulting in a relatively uniform drainage effect.

[0011] Preferably, the liquid detector includes an infrared light source and a photosensitive receiver, which are fixed at relative positions on the surface of the drainage cavity. The drainage cavity is transparent or has a transparent window, and the photosensitive receiver is connected to the control unit.

[0012] Infrared detection is non-contact, unlike pressure detection methods which directly contact the liquid, thus avoiding contamination issues. It can be reused multiple times without hygiene concerns. Furthermore, the transmission and reflection of infrared rays in air and liquids differ greatly, resulting in high detection sensitivity.

[0013] Preferably, the liquid level monitor includes an ultrasonic sensor, which is located at the bottom of the drainage container and is attached to the bottom surface of the drainage container through a coupling pad. During detection, the coupling pad is in close contact with the surface of the drainage container to emit ultrasonic waves. After the ultrasonic waves encounter the liquid surface, they are reflected and received again by the ultrasonic sensor. The signal is transmitted to the control unit, and the control unit can calculate the liquid level height.

[0014] Ultrasonic testing is non-contact, thus avoiding contamination issues caused by contact with liquid. Furthermore, ultrasound can directly measure liquid levels without being affected by the liquid's properties, ensuring accurate results. Its detection method is continuous monitoring, not fixed-point monitoring. Compared to infrared monitoring, it does not require waiting for the liquid level to reach a certain mark before triggering monitoring, exhibiting strong dynamic change capture performance and being unrestricted by distance.

[0015] If the ultrasonic sensor is placed directly close to the drainage container, the transmission of ultrasonic waves will be affected by the acoustic impedance of the air, causing the reflected waves to fail to reach the liquid surface, thus resulting in detection failure. Therefore, a coupling pad needs to be set to fill the gap between the ultrasonic sensor and the drainage container.

[0016] Alternatively, the liquid level monitor includes a multi-point array of infrared light sources, all of which are distributed perpendicular to the axis of the drainage container, and the number of photosensitive receivers corresponds to the number of infrared light sources and their positions are set opposite to them.

[0017] Infrared monitoring is also non-contact. Compared to ultrasonic monitoring, infrared monitoring does not need to consider acoustic impedance issues, but its continuity is relatively weaker than that of ultrasonic monitoring.

[0018] Preferably, the weight sensor obtains the weight of the first drainage fluid as M1, and the weight of the second drainage fluid as M2 after a unit time period. The control unit calculates the change in the weight of the drainage fluid per unit time as X by subtracting M2 from M1. The control unit sets the changes in the weight of the drainage fluid measured in consecutive time periods as X1, X2, X3... to form data.

[0019] If the first measurement of M1 is 0g, and the second measurement of M2 is 3.2g, then X1 is 3.2g; if the third measurement of M3 is 6.8g, then X2 is 3.6g...; and so on, we can obtain X1, X2, X3...

[0020] The weight sensor monitors weight changes in real time. The control unit calculates the change X every unit of time. The value per unit of time can be adjusted according to the patient's physical condition. Doctors can judge the previous data. If they judge that the patient has a large amount of fluid exudation and the exudation rate is fast, they can adjust the unit of time accordingly.

[0021] The change in the weight of the effusion, X, shows a regular curve that first increases and then decreases throughout the entire drainage period from start to finish. When X reaches its maximum value Xm, it begins to decline. During the decline period of the regular curve, if X2 > X1 occurs multiple times consecutively, preferably at least twice consecutively, or if X2 > Xm occurs suddenly, then the patient's wound effusion drainage is considered abnormal. If the liquid level monitor detects no change in liquid level for a period of time, the control unit controls the weight sensor to perform multiple consecutive weighings. If the X value is 0 after multiple weighings, it is determined that the liquid accumulation is abnormal. The control unit is connected to an alarm, which will be triggered when abnormal discharge of accumulated liquid is detected.

[0022] The weighing of the effusion may be subject to errors, and the amount of effusion discharged may fluctuate irregularly over a short period of time. Therefore, occasionally X2 > X1 may occur. This situation does not need to be judged as abnormal discharge. However, the error will not occur continuously. When X2 > X1 occurs continuously, it indicates that the patient's wound effusion discharge is abnormal.

[0023] If the measured value X2 suddenly exceeds Xm, it indicates abnormal fluid drainage and the possibility of sudden wound rupture, requiring immediate alarm and inspection.

[0024] In the early stages of drainage, the drainage volume will gradually increase. As the wound heals, the drainage volume will gradually decrease. If the drainage volume suddenly and continuously increases, it indicates a sudden problem in the healing process. At this time, the alarm will be triggered to alert the patient and medical staff, and further examination may be necessary.

[0025] If the fluid level does not change within a certain period of time during normal drainage, and the weight sensor does not show any increase in weight, there is a possibility of machine malfunction or pipeline blockage. An alarm should be triggered to notify medical staff for troubleshooting.

[0026] Preferably, the control unit is connected to a timer, and the control unit controls the drug delivery unit to automatically administer the drug according to the unit time. At this time, the value of the unit time must match the duration of the anesthetic's effect. The initial dosage is administered according to the clinical standard value, and the subsequent dosage is adjusted appropriately according to the calculated change in fluid accumulation. When X2 > X1, it reflects an increasing trend in fluid accumulation, and the delivery volume of the anesthetic is increased accordingly according to the clinical standard; when X2 < X1, it reflects a decreasing trend in fluid accumulation, and the delivery volume of the anesthetic is reduced accordingly.

[0027] Changes in the amount of fluid accumulation reflect the wound healing process. As the wound gradually heals and the pain decreases, the dosage of anesthetic should be gradually reduced.

[0028] Preferably, a recording electrode is provided near the nerve trunk in the implantation tube. The recording electrode senses electromyographic activity to reflect the effect of the anesthetic. The implantation tube is integrated with a wire, and the recording electrode is connected to an electromyography (EMG) device through the wire. The EMG device records the signal from the recording electrode to form EMG information. The EMG device and the control unit are connected to share the EMG information. The control unit determines whether to administer medication based on the EMG information.

[0029] Electromyography (EMG) is used to reflect muscle activity, thereby indicating whether the anesthetic is effective. Drainage can be resumed once the anesthetic takes effect. As the anesthetic gradually wears off, the EMG signal gradually increases. A threshold is pre-set; when the EMG activity exceeds the threshold, another dose can be administered. By monitoring the EMG signal as the basis for drug administration, the timing of drug administration and drainage can be controlled more precisely, facilitating a smooth transition between the two processes and maximizing the effectiveness of the anesthetic. At the same time, it takes into account the differences between patients, solving the problem of drug administration errors caused by differences in patient constitution. This makes the device more adaptable, suitable for both automated and manual drug administration.

[0030] Preferably, the control unit is set with a threshold A relative to the electromyographic information, and the control unit is connected to a drug administration button for autonomous drug administration. When the drug administration button is pressed, the control unit compares the real-time electromyographic information B with the threshold A. When B > A, it indicates that the anesthetic has failed, and the control unit controls the drug delivery unit to administer the drug. When B < A, it indicates that the anesthetic has not worn off, and the control unit provides deceptive feedback to the patient.

[0031] The system includes a self-administered dosing button, which, compared to automatic dosing, aims to reduce the frequency of anesthetic administration and minimize nerve damage caused by the drug. When the button is pressed, the control unit first determines whether the current electromyographic (EMG) activity meets the dosing criteria based on EMG data. The EMG signal forms a wave-like graph; once the anesthetic takes effect, the amplitude and frequency of this wave decrease until it disappears completely and becomes a straight line. An amplitude threshold A is set according to medical standards. If the EMG amplitude is greater than threshold A, it indicates that the anesthetic has failed, and dosing is permitted. If the EMG amplitude is less than threshold A, it indicates that the anesthetic has not failed or has not completely failed. In this case, the pain sensation is more psychological, so the system can provide the patient with a false sense of "successful dosing" without actually administering the medication, thus alleviating their psychological distress.

[0032] Preferably, the drug delivery unit includes a drug storage tank and a delivery mechanism. One end of the drug storage tank is connected to the implantation tube, and the delivery mechanism includes a hydraulic push rod and a piston connected thereto. The piston and the inner wall of the drug storage tank are connected in a cooperative manner.

[0033] Alternatively, the drug delivery unit has multiple parallel drug storage tanks, including a first drug storage tank and a second drug storage tank. The first drug storage tank is used to store anesthetics, and the second drug storage tank is used to store anti-inflammatory drugs. Both the first and second drug storage tanks are equipped with drug delivery pumps, which are connected to drug delivery branch tubes. Multiple drug delivery branch tubes converge into a main drug delivery tube, which is connected to the drug delivery chamber. Both the first and second drug storage tanks are equipped with level sensors to detect the amount of drug solution. Preferably, the drainage unit, drug delivery unit, and control unit are integrated into the monitoring host, and the drainage container and implantation tube are detachable from the monitoring host; To address hygiene and contamination issues, the implantation tube and drainage container are disposable consumables, separate from the monitoring host. They are detachably connected to the monitoring host and replaced each time they are used, thus avoiding cross-infection and bacterial growth.

[0034] Preferably, the monitoring host also includes a housing, and the drainage unit, drug delivery unit and control unit are all located inside the housing. The housing has an opening on the side opposite to the direction of the implantation tube and is provided with a cover. The cover is provided with an active channel for the implantation tube to pass through. The housing of the monitoring host is designed to be openable, which facilitates the replacement of the drainage container and the connection of the implantation tube.

[0035] Alternatively, the monitoring unit may also include a housing with a track inside, on which the drainage unit, drug delivery unit, and control unit are fixed to the bottom surface, and the bottom surface and the housing are slidably connected by the track; the housing of the monitoring unit is designed as a drawer to facilitate the replacement of the drainage container and the connection of the implantation tube.

[0036] Preferably, one end of the implantation tube and the drainage container is provided with a tip connector, the tip connector is provided with a valve, the tip connector is fixed relative to the monitoring host, and the tip of the tip connector is sealed to the drainage container. The top of the drainage container is equipped with a sealing cap, which is made of a flexible and soft material. The pointed end of the cap pierces the sealing cap and extends into the drainage container.

[0037] To address the complexities of docking the drainage container and the implantation tube, this application employs a pointed connector with a sharp tip and a rubber sealing cap. The combination of these two components not only ensures simple and convenient operation but also provides a strong seal.

[0038] Preferably, the valve includes an elastic baffle plate, with multiple baffle plates circumferentially distributed and fitted together to form a closed surface; when the connector and the drainage container are connected under negative pressure, the baffle plate opens under the action of negative pressure, allowing the drainage fluid to flow; when the connector is pulled out and the negative pressure state of the drainage container disappears, the baffle plate closes under its own elastic force, thus closing the valve when the connector is pulled out.

[0039] To address the issue of fluid leakage when removing the implantation tube during drainage container replacement, this application incorporates a valve designed for use under negative pressure conditions. This valve automatically closes when the implantation tube is removed, preventing fluid leakage, avoiding contamination of the monitoring unit, and better meeting hygiene requirements.

[0040] Preferably, a hydrophobic filter is provided between the drainage container and the air intake mechanism to prevent accumulated liquid from entering the air intake mechanism; an exhaust pipe is connected to the sealing cap, the exhaust pipe is connected to the drainage container, and the exhaust pipe is equipped with a hydrophobic filter.

[0041] To prevent the suction mechanism from being contaminated by accumulated liquid, this application installs a hydrophobic filter on the exhaust pipe used for drawing negative pressure, allowing only gas to pass through and preventing liquid from passing through, thus avoiding hygiene problems caused by accumulated liquid flowing into the suction mechanism.

[0042] Preferably, the drainage unit further includes a container fixing component, the bottom of which is connected to a telescopic component, and the container fixing component includes at least one fixing cavity, in which the drainage container is placed.

[0043] The telescopic component moves the container fixing part, realizing the mechanical control of the insertion of the drainage container and the implantation tube, which improves the degree of automation and reduces the need for manpower.

[0044] Preferably, the drainage container is a bottle or a bag, and the container fixing component is equipped with a fixing clip. When the drainage container is a bottle, the fixing clip is adapted to the shape of the bottle. When the drainage container is a bag, the fixing clip is adapted to the shape of the bottle. After the medical staff puts the drainage container in, they control the fixing clip to fix the drainage container.

[0045] The retaining clamp includes a drive unit and a clamp head, which is detachably configured to allow for removal depending on the type of drainage container.

[0046] Preferably, the container fixing component includes multiple fixing cavities, a rotating component is provided at the bottom of the container fixing component, and a locator is provided at the anti-drip interface.

[0047] Multiple drainage containers can be rotated and switched, and automatically connected to the implantation tube with the locator, reducing the number of times drainage containers need to be changed manually and enhancing the portability of the device.

[0048] The beneficial effects of this invention are as follows: (1) The present invention realizes integrated intelligent monitoring of automatic drainage and automatic drug administration. The drug administration unit and drainage unit are integrated into one unit through the control unit, so that the two processes can be switched intelligently and synchronously, reducing the frequent need for personnel, simplifying the manual operation process of traditional drug administration and drainage, and reducing labor.

[0049] (2) The present invention realizes intelligent collaborative control of drainage and drug administration. Through the collaborative feedback of liquid detector, liquid level monitor and weight sensor, the control unit can monitor the weight of the accumulated fluid in real time and dynamically adjust the dosage of anesthetic, realizing precise matching of drug administration and wound healing process, and significantly improving the safety of postoperative recovery.

[0050] (3) The present invention adopts a multi-level precise monitoring and abnormal early warning mechanism. By combining non-contact infrared liquid detection with ultrasonic / array infrared liquid level monitoring, it realizes high-sensitivity and pollution-free continuous dynamic monitoring of the drainage process. By analyzing the trend of the drainage fluid volume change, it can intelligently identify normal healing and abnormal conditions and trigger alarms in time, providing key decision support for medical staff.

[0051] (4) The drug administration control scheme of the present invention has the advantages of high precision and low cost. By integrating low-cost recording electrodes on a disposable implantable tube, electromyography is monitored. The muscle activity signal is used as the basis for drug administration. This not only achieves precise control and individualized adaptation of drug administration time, but also controls the cost of consumables and reduces production consumption.

[0052] (5) This invention implements the basic requirements of hygiene protection. Key contact components such as the implantation tube and drainage container are all designed as detachable disposable consumables to effectively prevent cross-infection. At the same time, the connector of the implantation tube is equipped with a negative pressure triggered automatic valve, which automatically seals to prevent leakage when pulled out. A hydrophobic filter is set at the connection between the suction mechanism and the drainage container, which only allows gas to pass through and avoids liquid accumulation from contaminating the suction mechanism.

[0053] (6) The present invention adopts a specially optimized implantation tube structure to improve patient comfort and drainage effect. The implantation tube body adopts an integrated design of drug delivery chamber and drainage chamber, which reduces the space occupied in the tissue and increases patient comfort. At the same time, the drainage chamber sidewall is provided with a porous and random protrusion structure, which effectively supports the surrounding tissue and prevents blockage, ensuring the uniformity and smoothness of the drainage area. In addition, the ends of the implantation tube body also extend towards the nerve trunk, realizing targeted drug delivery, improving the speed of anesthetic action and enhancing the analgesic effect.

Detailed Implementation

[0056] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0057] In the description of this application, it should be understood that the terms indicating connection relationships should be interpreted broadly. In this application, the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0058] Example 1 like Figure 1-3 As shown in Figures 6-11, an intelligent monitoring device for post-mental plasty surgery includes a drainage unit 11, a drug delivery unit 12, and a control unit 13, wherein the drainage unit 11 and the drug delivery unit 12 are both connected to the control unit 13; The drainage unit 11 includes a drainage container 111, which is connected to an implantation tube 2 and an aspiration mechanism 112, so that a negative pressure is formed inside the drainage container 111 for drainage. The drug delivery unit 12 is connected to the implantation tube 2. The implantation tube 2 is provided with independent channels for drainage and drug delivery. The control unit 13 controls the drug delivery unit 12 to deliver anesthetic to the implantation tube 2. A liquid detector 113 is installed at the implantation tube 2 to monitor the outflow of accumulated fluid. The drainage container 111 is equipped with a liquid level monitor 114 and a weight sensor 115 that are connected to the control unit 13. The liquid level monitor 114 is used to acquire liquid level data of the accumulated liquid, and the weight sensor 115 is used to acquire weight data of the accumulated liquid. The control unit 13 can calculate the continuous time period data variables of the liquid level data and weight data, thereby adjusting the delivery amount of anesthetic.

[0059] The intake mechanism 112 includes an air pump 1122 and an intake pipe 1121 connected thereto. The intake pipe 1121 is connected to the exhaust pipe 1112 of the drainage container 111.

[0060] The implantable tube 2 includes a drug delivery chamber 21 and a drainage chamber 22. The portion of the drug delivery chamber 21 and the drainage chamber 22 implanted in the body are integrated and extend to the nerve trunks on both sides. The portion of the drug delivery chamber 21 and the drainage chamber 22 outside the body are separated. The drug delivery chamber 21 is connected to the drug delivery unit 12, and the drainage chamber 22 is connected to the drainage container 111.

[0061] To avoid having too many tubes implanted in the surgical area, the internal implant is integrated to reduce space occupation, improve the patient's experience, and increase comfort during drainage; while the external implant is separate to facilitate monitoring.

[0062] The sidewall of the drainage cavity 22 has several drainage holes 221, and the outer wall of the drainage cavity 22 has several protrusions 222 randomly distributed to support the muscle tissue at the implantation site and prevent it from blocking the drainage holes 221. To address the issues of uneven drainage and easy blockage by muscles in a single drainage hole 221, the drainage cavity 22 has multiple drainage holes 221 distributed on its side wall, along with multiple protrusions 222, forming multiple drainage spaces and achieving simultaneous drainage from multiple locations, resulting in a relatively uniform drainage effect.

[0063] The liquid detector 113 includes an infrared light source 1141 and a photosensitive receiver 1142. The infrared light source 1141 and the photosensitive receiver 1142 are fixed at relative positions on the surface of the drainage cavity 22. The drainage cavity 22 is transparent or has a transparent window. The photosensitive receiver 1142 is connected to the control unit 13.

[0064] Infrared detection is non-contact, unlike pressure detection methods which directly contact the liquid, thus avoiding contamination issues. It can be reused multiple times without hygiene concerns. Furthermore, the transmission and reflection of infrared rays in air and liquids differ greatly, resulting in high detection sensitivity.

[0065] The liquid level monitor 114 includes an infrared light source 1141 arranged in a multi-point array. The infrared light sources 1141 are all distributed perpendicular to the axis of the drainage container 111. The number of photosensitive receivers 1142 corresponds to the number of infrared light sources 1141 and their positions are arranged opposite to them.

[0066] Infrared monitoring is also non-contact. Compared to ultrasonic monitoring, infrared monitoring does not need to consider acoustic impedance issues, but its continuity is relatively weaker than that of ultrasonic monitoring.

[0067] The weight sensor 115 is a high-precision sensor, and its accuracy should be at least 0.1g. The weight sensor 115 obtains the weight of the first drainage fluid as M1, and the weight of the second drainage fluid as M2 after a unit time period. The change in the weight of the drainage fluid per unit time is calculated by subtracting M2 from M1. The control unit 13 sets the changes in the weight of the drainage fluid measured in consecutive time periods as X1, X2, X3... to form data.

[0068] The change in the weight of the effusion, X, shows a regular curve that first increases and then decreases throughout the entire drainage period from start to finish. If X2 > X1 occurs multiple times consecutively, preferably at least twice consecutively, during the decreasing period of the regular curve, the patient's wound effusion drainage is considered abnormal. The weighing of the effusion may be subject to errors, and the amount of effusion discharged may fluctuate irregularly over a short period of time. Therefore, occasionally X2 > X1 may occur. This situation does not need to be judged as abnormal discharge. However, the error will not occur continuously. When X2 > X1 occurs continuously, it indicates that the patient's wound effusion discharge is abnormal.

[0069] The control unit 13 is connected to an alarm, which will trigger when an abnormality in the discharge of accumulated liquid is detected.

[0070] In the early stages of drainage, the drainage volume will gradually increase. As the wound heals, the drainage volume will gradually decrease. If the drainage volume suddenly and continuously increases, it indicates a sudden problem in the healing process. At this time, the alarm will be triggered to alert the patient and medical staff, and further examination may be necessary.

[0071] The drug delivery unit 12 includes a drug storage tank 121 and a pushing mechanism 122. One end of the drug storage tank 121 is connected to the implantation tube 2. The pushing mechanism 122 includes a hydraulic push rod and a piston connected thereto. The piston and the inner wall of the drug storage tank 121 are connected in a cooperative manner. A recording electrode 123 is provided near the nerve trunk in the implantation tube 2. The recording electrode 123 senses electromyographic activity to reflect the effect of the anesthetic. The recording electrode 123 is connected to an electromyography device 128 through a wire 124 integrated in the implantation tube 2. The electromyography device 128 records the signal of the recording electrode 123 to form electromyographic information. The electromyography device 128 is connected to the control unit 13 to share the electromyographic information.

[0072] Electromyography (EMG) is used to reflect muscle activity, thereby indicating whether the anesthetic is effective. Drainage can be resumed when the anesthetic is effective, and the EMG will gradually increase as the anesthetic wears off.

[0073] The control unit 13 automatically administers medication based on electromyographic information and adjusts the anesthetic dosage in conjunction with changes in drainage volume. When X2 > X1, it reflects an increasing trend in fluid accumulation, and the amount of anesthetic delivered increases accordingly; when X2 < X1, it reflects a decreasing trend in fluid accumulation, and the amount of anesthetic delivered decreases accordingly.

[0074] If the first dose is the standard value V, and X2 > X1 for the second dose, then the second dose V1 is greater than V. Similarly, if X3 < X2 for the third dose, then the third dose V2 < V1. Each dose is increased or decreased relative to the previous dose, and the dosage conforms to the clinical standard. The amount of fluid drainage reflects the wound healing process. As the wound gradually heals and the pain decreases, the dosage of anesthetic should be gradually reduced.

[0075] The following example illustrates the above principle using data: Based on clinical experience, the theoretical total drainage time is 24 hours, and the total drainage volume is approximately 50ml-100ml depending on the patient's condition. The effusion is a mixed solution of blood and tissue fluid, and its density is not constant. The density of blood is 1.050-1.060 g / ml, and the density of tissue fluid is 1.0-1.06 g / ml, both of which are very close to the density of water. Therefore, in clinical practice, the density of the effusion is often converted to the density of water, i.e., 1g / ml. The anesthetic used is lidocaine, a short-acting anesthetic that takes effect through local immersion. Its effect lasts for 1-2 hours, but the duration can vary depending on the patient's constitution. The unit time can also be adjusted based on the duration of the effect. Here, we take the theoretical value of 2 hours, so the unit time is 2 hours. Short-acting anesthetics take effect quickly and have a short duration. Patients are less likely to develop drug resistance with long-term use, so the impact of drug resistance on the duration of the effect can be ignored.

[0076]

[0077] The above charts can be used to form the following: Figure 3 The change curve shown; From the above table and Figure 3It can be seen that in the first 6 hours after the drainage begins, the fluid accumulation will continue to increase due to the lack of wound healing, forming an upward cycle. Around 6 hours later, X3 reaches its maximum value and begins to enter a downward cycle. During the downward cycle, X7 suddenly appears to be greater than X6, and X8 appears to be greater than X7 in succession. At this point, an abnormality in drainage is determined, an alarm is triggered, medical staff make a diagnosis, and after diagnosis, X gradually decreases and tends to return to normal. Finally, the drainage volume approaches 0, and the drainage ends.

[0078] The drainage unit 11, the drug delivery unit 12 and the control unit 13 are integrated into the monitoring host 1, and the drainage container 111 and the implantation tube 2 are detachable from the monitoring host 1; To address hygiene and contamination issues, both the implantation tube 2 and the drainage container 111 are disposable consumables, set up independently of the monitoring host 1. They are detachably connected to the monitoring host 1 and are replaced each time they are used, thus avoiding cross-infection and bacterial growth.

[0079] The monitoring host 1 also includes a housing 14, in which the drainage unit 11, the drug delivery unit 12, and the control unit 13 are all located. The housing 14 has an opening on the side facing the insertion direction of the implantation tube 2 and is provided with a cover. The cover is provided with a drug delivery interface, a drainage fixing port, and a wire interface. The drug delivery interface is connected to the drug storage tank 121. The drainage fixing port and the sealing cover 1111 are positioned correspondingly. The wire interface is connected to the control unit 13. It is also provided with an active channel 141 for the implantation tube 2 to pass through. The housing 14 of the monitoring host 1 is designed to be openable, which facilitates the replacement of the drainage container 111 and the connection of the implantation tube 2.

[0080] The end of the implantation tube 2 connected to the drainage container 111 is provided with a tip connector 23, the tip connector 23 is provided with a valve 231, the tip connector 23 is fixed relative to the monitoring host 1, and the tip of the tip connector 23 is sealed to the drainage container 111. The top of the drainage container 111 is provided with a sealing cap 1111, which is made of a flexible and soft material. The pointed connector 23 pierces the sealing cap 1111 and extends into the drainage container 111.

[0081] To solve the complex problem of docking the drainage container 111 and the implantation tube 2, this application adopts a pointed connector 23 with a pointed tip and a rubber sealing cap 1111. The combination of the two is not only simple and convenient to operate, but also has strong sealing performance.

[0082] Valve 231 includes an elastic baffle. When the connector 23 and the drainage container 111 are connected under negative pressure, the baffle opens under the action of negative pressure, allowing the drainage fluid to flow. When the connector 23 is pulled out and the negative pressure state of the drainage container 111 disappears, the baffle closes under its own elastic force, thus closing valve 231 when the connector 23 is pulled out.

[0083] To address the issue of fluid leakage when removing the implantation tube 2 during drainage container 111 replacement, this application incorporates a valve 231 designed for use under negative pressure conditions. This valve automatically closes when the implantation tube 2 is removed, preventing fluid leakage, avoiding contamination of the monitoring unit 1, and better meeting hygiene requirements.

[0084] An exhaust pipe 1112 is connected to the sealing cap 1111. The exhaust pipe 1112 is connected to the drainage container 111. The exhaust pipe 1112 is equipped with a hydrophobic filter 1113.

[0085] To prevent the suction mechanism 112 from being contaminated by accumulated liquid, this application provides a hydrophobic filter 1113 on the exhaust pipe 1112 used for drawing negative pressure, so that only gas can pass through and no liquid can pass through, thus avoiding hygiene problems caused by accumulated liquid flowing into the suction mechanism.

[0086] The drainage unit 11 also includes a container fixing member 116, the bottom of which is connected to a telescopic component 117. The container fixing member 116 includes at least one fixing cavity 1161, and the drainage container 111 is placed in the fixing cavity 1161.

[0087] The telescopic component 117 drives the container fixing component 116 to move, realizing the mechanical control of the insertion of the drainage container 111 and the implantation tube 2, which improves the degree of automation and reduces the need for manpower.

[0088] The container fixing component 116 includes multiple fixing cavities 1161, a rotating assembly 118 is provided at the bottom of the container fixing component 116, and a positioner is provided at the anti-drip interface.

[0089] The drainage container 111 is a bottle container fixing component 116 with a fixing clip inside to completely fix the drainage container; The telescopic component 117 and the rotating component 118 can be implemented using existing technologies, so they will not be described in detail here.

[0090] Multiple drainage containers 111 can be rotated and switched, and automatically connected to the implantation tube 2 with the locator, reducing the number of times the drainage containers 111 need to be changed manually and enhancing the portability of the device.

[0091] During use, medical staff open the cover, place the drainage container 111 into the fixed cavity 1161, connect the exhaust pipe 1112 and the inlet pipe 1121, close the cover, connect the drug delivery chamber 21 of the implanted tube 2 to the drug delivery interface, fix the tip connector 23 of the drainage chamber 22 to the drainage fixation port, connect the wire 124 to the wire interface, and the rotating component 118 automatically positions the drainage container 111 and the connector 23 with the assistance of the positioner. The telescopic component 117 pushes the container fixing part 116 up to make the tip connector... The head 23 is inserted into the sealing cap 1111. The suction mechanism 112 draws air to create negative pressure inside the drainage container 111 to drain the accumulated fluid. During this process, the liquid detector 113 monitors the flow of the accumulated fluid. The liquid level monitor 114 monitors the liquid level height inside the drainage container 111. The weight sensor 115 takes the first measurement, weighs the empty drainage container 111 and records the weight as M1, setting this as the baseline 0. The recording electrode 123 records the electromyographic activity and transmits it to the control unit 13 to form an electromyogram. When inserting the implantation tube, anesthesia is administered according to the clinical standard dosage. The medication is administered, and the duration of the anesthetic's effect is recorded using electromyography to determine the unit time for the weight sensor 115 to measure the effusion weight. Once the anesthetic wears off, the unit time is determined. At this point, the weight sensor 115 weighs the effusion a second time to obtain the weight M2. From this point onward, weights are measured unit by unit time to obtain M3, M4, and so on, and the changes X1, X2, X3, and so on are calculated. Each measurement completes one medication cycle. At this point, drainage is stopped, and the dosage of anesthetic is increased or decreased based on the comparison of X and clinical standards. The medication is administered until the muscle... The electrocardiogram shows that drainage resumes after the anesthetic takes effect. During this process, according to the regular curve, if an abnormality is detected, an alarm is triggered. When the liquid level monitor 114 detects that the drainage container 111 is full, the control unit 13 controls the telescopic component 117 to descend, so that the full drainage container 111 and the connector 23 are disconnected. The rotating component 118 rotates to replace the new drainage container 111 and reconnects it to the connector 23 to continue drainage. After 24 hours, when the weight of the accumulated fluid is close to 0 and the liquid detector 113 detects no flow of accumulated fluid, the drainage ends.

[0092] Example 2; like Figure 4 As shown, the difference from Embodiment 1 is that in this embodiment:

[0093] After the drainage begins, it reaches its maximum value of X3 in about 6 hours and then enters a downward cycle. During the downward cycle, X7 suddenly appears to be greater than X6 and X7 is greater than the maximum value of X3. At this point, an abnormality is detected, an alarm is triggered, and medical staff make a diagnosis. After the diagnosis, X gradually decreases and tends to return to normal. Finally, the drainage volume approaches 0, and the drainage ends.

[0094] Example 3 like Figure 5As shown, the difference from Embodiment 1 is that in this embodiment, the control unit 13 does not control the drug delivery unit 12 to automatically administer drugs, but instead allows the patient to administer drugs independently by setting a drug delivery button.

[0095] The control unit 13 is set with a threshold A relative to the electromyographic information. The control unit 13 is connected to a drug administration button for autonomous drug administration. When the drug administration button is pressed, the control unit 13 compares the real-time electromyographic information B with the threshold A. When B > A, it indicates that the anesthetic has failed, and the control unit 13 controls the drug delivery unit 12 to deliver the drug. When B < A, it indicates that the anesthetic has not expired, and the control unit 13 provides deceptive feedback to the patient.

[0096] The system includes a drug administration button to allow patients to administer drugs autonomously. Compared to automatic drug administration, this feature aims to reduce the frequency of anesthetic administration and minimize nerve damage caused by the anesthetic. When the drug administration button is pressed, the control unit 13 first determines whether the current electromyographic (EMG) activity meets the drug administration criteria based on EMG information. The EMG graph is a wave-like line. When the anesthetic takes effect, the amplitude of the wave-like line decreases and the fluctuation frequency decreases until it disappears completely and becomes a straight line. An amplitude threshold A is set according to medical standards. When the amplitude of the EMG signal is greater than the threshold A, it indicates that the anesthetic has failed, and drug administration is allowed. When the amplitude of the EMG signal is less than the threshold A, it indicates that the anesthetic has not failed or has not completely failed. In this case, the pain sensation is more psychological, so the patient can be given a false feedback of "successful drug administration" without actually receiving the drug, thus providing psychological relief.

[0097] Example 4 The difference from Embodiment 1 is that: in this embodiment, no recording electrode 123 is provided at the implantation tube 2. In this embodiment, the control unit 13 is connected to a timer, and a flow meter is provided at the connection between the drug delivery unit 12 and the implantation tube 2. Both the timer and the flow meter are connected to the control unit 13, and the control unit 13 controls the drug delivery unit 12 to deliver drugs at regular intervals and in quantitative amounts.

[0098] The dosing interval is calculated based on the average effective time of the anesthetic, and the value of the unit time is equal to the average effective time. The dosage is controlled and detected by a flow meter.

[0099] Example 5 like Figure 12As shown, the difference from Embodiment 1 is that: in this embodiment, the liquid level monitor 114 does not use an infrared light source 1141 and a photosensitive receiver 1142. In this embodiment, the liquid level monitor 114 includes an ultrasonic sensor 1143. The ultrasonic sensor 1143 is located at the bottom of the drainage container 111 and is attached to the bottom surface of the drainage container 111 through a coupling pad 1144. During detection, the coupling pad 1144 is in close contact with the surface of the drainage container 111 and emits ultrasonic waves. After encountering the liquid surface, the ultrasonic waves are reflected and received again by the ultrasonic sensor 1143. The signal is transmitted to the control unit 13, and the control unit 13 can calculate the liquid level height.

[0100] Ultrasonic testing is non-contact, thus avoiding contamination issues caused by contact with liquid. Furthermore, ultrasound can directly measure liquid levels without being affected by the liquid's properties, ensuring accurate results. Its detection method is continuous monitoring, not fixed-point monitoring. Compared to infrared monitoring, it does not require waiting for the liquid level to reach a certain mark before triggering monitoring, exhibiting strong dynamic change capture performance and being unrestricted by distance.

[0101] If the ultrasonic sensor 1143 is placed directly close to the drainage container 111, the transmission of ultrasonic waves will be affected by the acoustic impedance of the air, causing the reflected bounce to fail to reach the liquid surface, thus causing the detection to fail. Therefore, a coupling pad 1144 needs to be set to fill the gap between the ultrasonic sensor 1143 and the drainage container 111.

[0102] Example 6 like Figure 13 As shown, the difference from Embodiment 1 is that: no propulsion mechanism is provided in this embodiment. The drug delivery unit 12 in this embodiment includes a drug storage tank 121 and a drug delivery pump 125. The drug delivery pump 125 is located in the drug storage tank 121 and is connected to the drug delivery chamber 21 of the implantation tube 2 through a pipe.

[0103] Example 7 like Figure 14 As shown, the difference from Embodiment 1 is that: in this embodiment, the drug delivery unit 12 has multiple drug storage tanks 121 arranged in parallel, each drug storage tank 121 is equipped with a corresponding drug delivery pump 125, the drug delivery pump 125 is connected to a drug delivery branch pipe 126, the drug delivery branch pipe 126 converges into the drug delivery main pipe 127, each drug delivery branch pipe 126 is equipped with a control valve, and the drug delivery main pipe 127 is connected to the drug delivery chamber 21.
