Description

Technical Field

[0001] This invention relates to the field of electrical impedance imaging technology, and in particular to an electrical impedance imaging information acquisition device. Background Technology

[0002] Acute respiratory distress syndrome (ARDS) is a clinical syndrome characterized by persistent hypoxemia, caused by intrapulmonary or extrapulmonary factors. It is a common and serious respiratory critical illness that severely threatens human health. As early as World War I, Pasteur termed extensive atelectasis caused by chest injuries in soldiers as pulmonary contusion. In 1945, Burford et al. termed lung damage caused by chest and abdominal injuries as wet lung. In 1946, Brewer et al. reported increased respiratory secretions in war wound patients and termed it wet lung syndrome. In 1948, Moon first described acute respiratory distress following trauma, burns, sepsis, and major surgery. Pulmonary edema as a complication of non-chest trauma was documented during the Korean War. It received further attention during the Vietnam War, with hundreds of critically ill patients with non-chest war injuries frequently developing shock lung, then known as Da Nang Lung. Because there are over 100 primary diseases that can cause ARDS, and some of these diseases, although unrelated to the respiratory system, can still cause symptoms such as respiratory distress, this has led to confusion in nomenclature. Over the past half-century, more than 30 synonyms for ARDS have emerged. Since the concept of ARDS was first proposed in 1967, scientists from various countries have conducted extensive research to improve the prognosis of ARDS patients.

[0003] Despite the rapid development of clinical medicine, ARDS remains a common cause of respiratory failure in critically ill patients, and its high incidence and mortality rates have not been significantly improved [2]. A study published in JAMA in 2016 analyzed 459 intensive care units (ICUs) in 50 countries. The data showed that the mortality rate of ARDS still reached more than 40%, and domestic epidemiological data showed that the rate was as high as 50-68.7%. Various drug treatments have not shown that they can significantly improve the prognosis of ARDS, and mechanical ventilation is still the main intervention and adjuvant treatment for ARDS.

[0004] Current mechanical ventilation systems, due to improper ventilator parameter settings or failure to adjust parameters in a timely manner when the patient's condition changes, can lead to increased lung tissue permeability, resulting in fluid accumulation, lung collapse injury, and inflammatory responses. Currently, the function of matching ventilator parameter settings to the patient's respiratory status during mechanical ventilation cannot respond quickly, or provide rapid feedback.

[0005] Therefore, while existing clinical technologies can meet the needs of ARDS diagnosis and assessment, none of them can achieve real-time monitoring of lung ventilation distribution during mechanical ventilation in ARDS patients.

[0006] There is an urgent clinical need for a device that can be used for bedside monitoring and real-time dynamic functional imaging technology to monitor and evaluate the lung ventilation status and PEEP titration process during mechanical ventilation in ARDS patients. Summary of the Invention

For example, in the case of infectious diseases such as rabies, it can reduce the situation where patients struggle and cause harm to medical staff; or in the case of other airborne infectious diseases during the viral replication period, it can reduce the frequency of medical staff having direct contact with patients, thereby improving the work safety of medical staff.

[0045] In addition, since the determination of the extrusion volume and dripping position of the conductive emulsion is fully automated, it can reduce the possibility of inaccurate monitoring results caused by excessive displacement of the electrode plate during operation by medical staff.

Detailed Implementation

[0065] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0066] according to Figure 1-11 As shown, this embodiment of the invention provides an electrical impedance imaging information acquisition device, including: an acquisition unit and a monitoring unit 1. The acquisition unit is used to acquire resistance information and transmit the resistance information to the monitoring unit 1; the monitoring unit 1 is used to perform imaging based on the resistance information and feed the imaging information back to the mechanical ventilation device 2; and is used to adjust the air output of the mechanical ventilation device 2 in real time.

[0067] The acquisition unit includes an electrode strip 5 and an electrode wire 4. Multiple boxes 27 are evenly distributed on the electrode strip 5, and each box 27 is provided with an electrode. Each electrode is connected to the monitoring unit 1 through the electrode wire 4.

[0068] In this invention, the electrode strip 5 is used to fit the patient's chest cavity through the electrode pad 37, thereby realizing the acquisition of information from the chest cavity using the electrode pad 37. The information acquired from the chest cavity is further fed back to the monitoring unit 1 through the electrode wire 4. The monitoring unit and the mechanical ventilation device 2 are connected through the signal wire 6, and the monitoring unit is used to control the oxygen output of the mechanical ventilation device 2 according to the respiratory information of the monitoring unit 1.

[0069] Furthermore, the monitoring unit 1 adjusts the air pressure of the ventilation tubing 3 of the mechanical ventilation device 2 based on the collected chest cavity information, so that the air pressure output from the ventilation tubing 3 meets the respiratory pressure required by the patient. This reduces the need for oxygen to enter the patient's lungs when the patient experiences respiratory distress, thereby alleviating the symptoms of respiratory distress. Therefore, this invention, by more accurately monitoring the patient's respiratory data and adjusting the oxygen output of the mechanical ventilation device based on the precise respiratory data, enables the patient to reduce complications related to respiratory distress. It can also provide timely response or rapid feedback of the patient's lung parameters during mechanical ventilation for patients with respiratory distress, thereby reducing the occurrence of ventilation-related lung injury caused by excessively high or low positive end-expiratory pressure (PEEP) during mechanical ventilation.

[0070] In one embodiment, the electrode strip 5 includes: a ring track 25, which is mounted on an operating table 7 and fitted onto the bed board of the operating table 7. The bottom surface or sides of the bed board of the operating table 7 are connected to the annular inner wall of the ring track 25 via multiple sixth links 36; multiple boxes 27 are spaced apart on the ring track 25, and each box 27 is provided with multiple electrode outlets 28 for extending electrode pads 37; the head of the operating table 7 is provided with a backrest 8, and the backrest 8 contains... A cabin 10 is provided, and a sealing door 9 is provided on the side of the cabin 10 near the bed board. First motors 32 are installed at intervals on the inner wall of the side of the cabin 10 away from the sealing door 9. Each first motor 32 is connected to a fifth link 31. The other end of each fifth link 31 is rotatably connected to one side of the annular track 25. Multiple fourth links 26 are evenly distributed on the other side of the annular track 25. The fourth links 26 and the box 27 sleeved on the annular track 25 cooperate with each other and are used for the box 27 to rotate around the annular track 25.

[0071] The annular inner wall of the annular track 25 is provided with a second groove 43, and a second slider 39 is slidably disposed on the second groove 43. The end of the second slider 39 away from the second groove 43 is supported on the two sides or the bottom surface of the operating table 7 through a sixth connecting rod 36. The side of the annular track 25 near the backrest 8 is slidably connected to the fifth connecting rod 31. The outer wall of the annular structure of the annular track 25 is provided with a first meshing groove 29. A vertical rod 42 is supported on the bottom surface of the operating table 7. A second motor 41 is installed on one side of the vertical rod 42. The output end of the second motor 41 is connected to a first rotating shaft 34. The other end of the first rotating shaft 34 is connected to a gear 33. The gear 33 and the first meshing groove 29 mesh with each other and are used to drive the annular track 25.

[0072] The box 27 is designed as a ring structure, and each ring structure has a second meshing groove 35 on its inner wall. The second meshing groove 35 is an internal meshing tooth, and the teeth of the internal meshing tooth are circular arc gear 33. The second meshing groove 35 meshes with the fourth connecting rod 26 and rotates according to the rotation of the ring track 25. An electrode rod 38 extending outward from the electrode outlet 28 is provided inside the box 27. The extended end of the electrode rod 38 is used to connect to the electrode plate 37, and the electrode plate 37 is used to be placed in the patient's chest cavity. The electrode rod 38 is fixed on an adjustment mechanism, which is used to adjust the position of the electrode rod 38.

[0073] In this embodiment, the annular track 25 of the ring structure can extend outward from the cabin 10 of the backrest 8 when in use, and can be stored in the cabin 10 when not in use, so as to save space.

[0074] In practice, the sealing door 9 is first opened and the first motor 32 is started. After the first motor 32 starts working, it will extend and retract the fifth link 31. The fifth link 31 extends and retracts with the start of the first motor 32, thereby sending the annular track 25 out of the cabin 10 of the backrest 8. Since the annular track 25 is mounted on the operating table 7 through the sixth link 36, the annular structure of the annular track 25 will move horizontally on the operating table 7 with the fifth link 31 after the first motor 32 starts, so that the annular track 25 reaches the predetermined position of the patient's chest cavity.

[0075] Next, if the motor outlet position on the surface of the box 27 is offset, i.e., it cannot fit the patient's chest cavity, the second motor 41 is activated. After the second motor 41 is activated, it can rotate the first rotating shaft 34. The first rotating shaft 34 rotates the gear 33. The gear 33 further engages with the first meshing groove 29 on the outer wall of the annular track 25, thereby realizing the purpose of rotating the box 27 with the annular track 25. Since the multiple fourth connecting rods 26 provided on one side of the annular track 25 can mesh with the second meshing groove 35 on the inner wall of the annular box 27, the annular track 25 can rotate with the gear 33 and rotate the box 27 through the fourth connecting rods 26; that is, the box 27 can rotate independently on the annular track 25, thereby moving the electrode outlet 28 provided on the box 27.

[0076] In actual use, human skin is the part of the body with the worst conductivity. Oils, dander, sweat and other deposits on the skin surface can also hinder the passage of current, which can cause the electrode pad 37 to detach from the chest cavity or make poor contact. Therefore, during long-term monitoring, the conductivity of the electrode pad 37 will decrease after the patient sweats in the chest cavity. At this time, by using the extension and retraction of the fifth link 31 and the rotation of the box 27 on the annular track 25, the position of the electrode outlet 28 can be adjusted. This allows the position of the electrode outlet 28 to be adjusted without changing the patient's body position, thereby enabling the electrode pad 37 to be replaced at multiple monitoring points in one area. This reduces the situation where the impedance of the electrode pad 37 increases due to sweat accumulation in one area after prolonged contact with the electrode pad 37.

[0077] To facilitate the stable installation of the annular track 25 on the operating table 7, the second sliding groove 43 provided on the annular inner wall of the annular track 25 can be used to install it on the operating table 7 via the sixth connecting rod 36. Furthermore, the other end of the sixth connecting rod 36 is slidably disposed on both sides or the inner bottom surface of the operating table 7 via a sliding rail structure. This allows the sixth connecting rod 36 to reciprocate on the operating table 7 along with the sliding rail structure when the annular sliding rail reciprocates with the fifth connecting rod 31, thereby achieving the purpose of supporting the annular track 25.

[0078] The outer wall of the annular track 25 is also provided with annular limiting rods 40 at intervals. The annular inner wall of the annular limiting rod 40 is connected to the seventh connecting rod 64. The end of the seventh connecting rod 64 away from the annular limiting rod 40 is connected to the slide rail structure provided on the operating table 7. The two ends of the annular limiting rod 40 are respectively connected to the box body 27 and are used to support or mount the box body 27 on the annular track 25.

[0079] Both sides of the box body 27 are provided with annular sliding grooves, which are used for sliding the end of the annular limiting rod 40.

[0080] The annular track 25 is composed of multiple arc-shaped tracks spliced ​​together. The splicing ends of each arc-shaped track are connected by buckles 44 to form an annular track 25 with an annular structure. This allows the annular track 25 to have its annular inner diameter adjusted or selected, so that it can be matched with different models or uses of operating tables 7 during installation and use.

[0081] In one embodiment, the adjustment mechanism includes: a second sliding plate 52, one side of which is connected to an electrode rod 38 or a third motor for driving the electrode rod 38; the other side of the second sliding plate 52 is provided with a second fixed platform 49, the second fixed platform 49 is threadedly connected to a screw 50, the screw 50 is mounted on the inner wall of the housing 27 via two first fixed platforms 48, one end of the screw 50 is connected to a second rotating shaft 51, the other end of the second rotating shaft 51 is connected to a fourth motor, the fourth motor is used to drive the second rotating shaft 51 to rotate the screw 50; one side of the second sliding plate 52 is connected to a first sliding plate 47, the first sliding plate 47 and the second sliding plate 52 form an L-structure, the surface of the first sliding plate 47 near the L-shaped opening of the L-structure is provided with a slide rail 60, a horizontal plate 45 is also provided inside the housing 27, a second slide rail 46 is provided on the horizontal plate 45, the second slide rail 46 and the slide rail 60 cooperate with each other and are used for the reciprocating movement of the first sliding plate 47 and the second sliding plate 52 inside the housing 27.

[0082] In the previous embodiment, the purpose was that the fifth link 31 could adjust the position of the annular track 25 on the plane of the operating table 7, that is, the extension and retraction of the fifth link 31 could enable the box 27 to reciprocate above the operating table 7, and the direction of the reciprocating motion was adjusted from the head to the foot of the bed; at the same time, the rotation of the gear 33 could enable the box 27 itself to rotate on the annular track 25, thereby enabling the electrode outlet 28 on the box 27 to be adjusted, that is, to ensure that the motor outlet on the box 27 could be adjusted with the patient's body, so that the electrode pad 37 could better fit the patient's chest cavity.

[0083] Furthermore, in this embodiment, the electrode outlet 28 can be configured as a long strip structure, and the adjustment mechanism can adjust the spacing or position of two adjacent electrode pieces 37, thereby achieving the purpose of replacing monitoring of multiple monitoring points in a region; specifically, firstly, the fourth motor is started, and the fourth motor will rotate the second rotating shaft 51, further realizing the rotation of the screw 50 mounted on the first fixed platform 48 inside the box 27. After the screw 50 rotates, the threaded hole on the second fixed platform 49 and the screw 50 will cooperate with each other, further realizing the reciprocating motion of the second sliding plate 52 along the axial extension direction of the screw 50; further realizing the purpose of adjusting the position of the electrode rod 38 connected on the second sliding plate 52, thereby enabling the electrode piece 37 connected to the electrode rod 38 to be adjusted in the left and right directions above the operating table 7;

[0084] At this point, the operating table 7 is defined using x, y, and z axes. The height of the operating table 7 is the z-axis, the direction from the head to the foot of the operating table 7 is the y-axis, and the two sides of the operating table 7 are the x-axis. The reciprocating motion of the second sliding plate 52 allows the electrode plate to be adjusted in the x-axis direction. The fifth connecting rod 31 allows the electrode plate to be adjusted in the y-axis direction, and the retractable electrode rod 38 allows the electrode plate to move in the z-axis direction. Furthermore, by rotating the box 27 around the annular structure of the annular track 25, the fourth axis direction is adjusted, i.e., the box 27 rotates. This achieves the purpose of adjusting the position of the electrode pads 37 in multiple directions, ensuring that even with fewer personnel, the solution provided by this invention can achieve fully automatic placement or use of the electrode pads 37 to collect information from the patient's chest cavity. Two sets of the annular track 25 can be set at the head and foot of the bed respectively, thereby enabling the arrangement of 3-lead or 5-lead electrode pads 37 for the patient.

[0085] In this embodiment, by adjusting the position of the electrode collection points, the electrode can collect more accurate respiratory data, thereby assisting the mechanical ventilation device in regulating the oxygen output.

[0086] In one embodiment, the side of the first slide plate 47 away from the slide rail 60 is provided with a third slide groove 55, the third slide groove 55 is designed with a triangular structure, a third slider 54 is slidably disposed in the third slide groove 55, one end of the third slider 54 away from the third slide groove 55 is disposed on a second connecting post 53, a push rod 56 is provided on the circumferential outer wall of the second connecting post 53, the outer wall of the push rod 56 is movably sleeved on a limiting sleeve 57, the other end of the push rod 56 is connected to a second push plate 65, the second push plate 65 is used to squeeze the storage bladder 66, a bladder tube 67 is connected to the storage bladder 66, one end of the bladder tube 67 away from the storage bladder 66 is connected to an injection pipe 69; the box body 27 is provided with an outlet 30, the outer wall of the outlet 30 is provided with a conical annular limiting platform 68, the annular limiting platform 68 and the outlet 30 are both used for the extension of the injection pipe 69.

[0087] The second connecting post 53 has a second slot 62 on one side, and a limiting post 61 is provided at the bottom of the slot 62. A spring 63 is sleeved on the limiting post 61. The third slider 54 has a first slot 59 on one side, and the first slot 59 is sleeved on the limiting post 61. The third slider 54 reciprocates within the second slot 62.

[0088] One end of the spring 63 is fixedly connected to the bottom of the second slot 62, and the other end of the spring 63 is connected to the bottom of the first slot 59. The openings of the first slot 59 and the second slot 62 are arranged opposite to each other.

[0089] In this embodiment, alcohol or cleaning solution may be output through the outlet 30 to clean the location where the electrode pad 37 needs to be placed, thereby facilitating better contact between the electrode pad 37 and the skin of the patient's chest cavity, further reducing the possibility that the electrode pad 37 may not fit well due to human oil and dander in the chest cavity. During operation, the second sliding plate 52 will carry the first sliding plate 47 to reciprocate on the horizontal plate 45 during its reciprocating motion, further enabling the third slider 54 to reciprocate on the triangular third slide groove 55. Since the triangular third slide groove 55 can limit the range and position of the third slider 54, the third slider 54 will carry the second connecting column 53 and the push rod 56 to reciprocate.

[0090] Specifically, when the third slider 54 moves in the third slide groove 55 of the triangular structure, the position of the push rod 56 remains unchanged when it is located at the base of the triangle; when the third slider 54 slides from the base to the side of the triangular structure, the push rod 56 will move on the limiting sleeve 57 under the push of the reciprocating motion of the first slide plate 47; the limiting sleeve 57 is supported on the inner wall of the horizontal plate 45 or the box 27 by the support rod 58, thereby enabling the push rod 56 to perform linear motion;

[0091] Furthermore, the push rod 56 moves the second push plate 65, which squeezes the storage sac 66 during reciprocating motion, causing the liquid inside the storage sac 66 to flow out, thus achieving the purpose of output through the sac tube 67 and the injection pipe 69. During the output process, a sponge can be installed at the outlet of the injection pipe to achieve uniform liquid output. Furthermore, in order to facilitate cleaning of the patient's chest area skin and to allow the electrode pad 37 to fit better, the second motor 41 can be activated to drive the gear 33, causing the gear 33 to move along the annular track 25. This further causes the box 27 to rotate around the annular track 25, thereby allowing the liquid outlet 30 on the box 27 to rotate. This further utilizes the injection pipe with sponge to wipe the patient's skin, reducing the need for manual operation by medical staff and thus reducing direct contact between medical staff and patients when exposed to high-risk working environments.

[0092] In addition, when a patient needs defibrillation during electrocardiogram monitoring, conductive media such as alcohol, cleaning solution, conductive glue, conductive ointment, and conductive emulsion can be output through the outlet 30 set on the annular track 25. At the same time, after the conductive media is output, defibrillation can be performed on the patient through the defibrillator.

[0093] In actual use, the annular track 25 can be retracted into the cabin 10 with one click, or the position of the annular track 25 can be retained on the operating table 7, depending on the actual situation.

[0094] In this embodiment, cleaning the electrode collection points allows the electrodes to better fit the patient's chest cavity, reducing the electrode resistance and enabling the electrodes to collect more accurate respiratory data, thereby assisting the mechanical ventilation device in regulating oxygen output.

[0095] In one embodiment, the opening of the cabin 10 is provided with a first slide rail 11, and the sealing door 9 is provided with first sliders 12 on both the upper and lower sides of the side near the cabin 10. The first sliders 12 reciprocate on the first slide rail 11, and the sealing door 9 is a folding door structure. The top surface of the sealing door 9 is provided with first connecting posts 23 at intervals. The first connecting posts 23 are used to connect first connecting rods 14. A connecting frame 24 is connected between two first connecting rods 14. A third connecting post extending upward is provided between the first connecting rods 14 and the connecting frame 24. The top surface of the backrest 8 is provided with a Z-shaped track 13, and the third connecting post is slidably mounted on the Z-shaped track 13. The top surface of the backrest 8 is also provided with second connecting plates 18 at intervals. The end of the second connecting plate 18 away from the top surface of the backrest 8 is connected to the first connecting plate 1. 7. The first connecting plate 17 has a third connecting rod 16 at each end. The third connecting rod 16 is a tubular structure. A second connecting rod 15 is movably sleeved inside the tubular structure. The other end of the second connecting rod 15 is connected to the first push plate 22. The first push plate 22 is also provided with a U-shaped fixing frame 21. The U-shaped fixing frame 21 is located between the two second connecting rods 15. The U-shaped slot of the U-shaped fixing frame 21 is engaged and fixed on the first push plate 22. The other end of the U-shaped fixing frame 21 is connected to the third connecting plate 19. The other side of the third connecting plate 19 is connected to the side wall of the Z-shaped track 13. The lower surface of the first push plate 22 is used to install a telescopic motor. The telescopic end of the telescopic motor is provided with a defibrillator. Alternatively, the upper surface of the first push plate 22 is provided with a storage box for storing or placing items.

[0096] In this embodiment, the cabin 10 is used to store the defibrillator or the circular track 25. Specifically, when it is needed to work, a drive motor is provided on one side of the sealing door 9, and the drive motor can open or close the sealing door 9.

[0097] When the sealing door 9 is opened, the first sliders 12 at the upper and lower ends of the sealing door 9 will cooperate with the first slide rail 11 set at the opening end of the cabin 10 and achieve the purpose of opening the sealing door 9; during the opening process of the sealing door 9, the sealing door 9 moves on the Z-shaped track 13 through the first connecting column 23, carrying the first connecting rod 14 and another first connecting column 23 connected to the first connecting rod 14.

[0098] Since the Z-shaped track 13 is connected to the first push plate 22 through the third connecting plate 19, and the first push plate 22 is further movably mounted on the third connecting rod 16 through the second connecting rod 15, when the sealing door 9 moves, the first connecting columns 23 at both ends of the first connecting rod 14 will move, thereby pulling or driving the Z-shaped track 13 to move. The Z-shaped groove 20 of the Z-shaped track 13 will restrict the movement position of the first connecting column 23, thereby allowing the first push plate 22 connected to it to move horizontally from the top surface of the backrest 8 toward the top of the operating table 7, thereby realizing the purpose of horizontal movement of the defibrillator or storage box by using the sliding sleeve structure of the second connecting rod 15 and the third connecting rod 16.

[0099] If a defibrillator is used, the defibrillator will activate its telescopic motor based on the output of the conductive medium, and the telescopic motor will move the electrode plates of the defibrillator to the patient's chest cavity, thereby using the defibrillator to deliver an electric shock to the area of ​​the patient coated with the conductive medium for defibrillation.

[0100] If you bring a storage box, it will be convenient to store some first aid equipment or materials, such as first aid kits, so that you can take first aid measures for patients in case of an emergency.

[0101] In one embodiment, the second pusher 65 is used to expel the conductive medium stored in the storage sac 66, and to expel or apply the conductive medium into the patient's pleural cavity; the injection conduit 69 is also provided with a metering device, which expels the conductive medium according to the following method:

[0102] Step 1: Determine the extrusion position of the conductive medium and the extrusion amount of the conductive emulsion based on the preset position of the electrode strip 5.

[0103] Step 2: Based on the obtained extrusion position and extrusion amount, discharge the conductive medium from the outlet end of the device to the preset position;

[0104] Step 3: Based on the preset position of electrode strip 5 and the dripping position of conductive medium, start the telescopic motor and use the telescopic motor to send the defibrillator above the dripping position of conductive medium.

[0105] Step 4: Start the electrode pads 37 or the defibrillator.

[0106] This invention provides an electrical impedance imaging information acquisition device to enable timely response or rapid feedback of lung parameters in patients with respiratory distress syndrome undergoing mechanical ventilation, so as to reduce ventilation-related lung injury caused by excessively high or low positive end-expiratory pressure (PEEP) during mechanical ventilation.

[0107] In this embodiment, the conductive emulsion can determine the dripping position and dripping amount of the conductive emulsion according to the preset position of the electrode strip 5. Furthermore, the dripping position of the conductive emulsion delivered by the defibrillator is realized through the telescopic mechanism, and the electrode plate of the defibrillator is brought into contact with the conductive emulsion, so that the patient's electric shock point can be effectively attached to the electrode plate, thereby achieving the purpose of reliable power supply.

[0108] At the same time, it can also achieve the purpose of automatically squeezing conductive emulsion and placing electrode plates for patients of different heights, weights, or ages, reducing the situation of low work efficiency caused by insufficient nursing staff in hospitals.

[0109] At the same time, in special cases, it can also reduce the situation where medical staff have direct contact with patients. For example, in the case of infectious diseases such as rabies, it can reduce the situation where patients struggle and cause harm to medical staff; or in the case of other airborne infectious diseases during the viral replication period, it can reduce the frequency of medical staff having direct contact with patients, thereby improving the work safety of medical staff.

[0110] In addition, since the determination of the extrusion volume and dripping position of the conductive emulsion is fully automated, it can reduce the possibility of inaccurate monitoring results caused by excessive displacement of the electrode plate during operation by medical staff.

[0111] In addition, during actual use, the box 27 is provided with a flip cover, which is used to open or close the box 27, thereby enabling the internal components of the box 27 to be repaired or maintained.

[0112] In this embodiment, the conductive medium includes, but is not limited to, conductive media or cleaning liquids that facilitate better conductivity of the electrode sheet 37 or electrode plate, such as alcohol / cleaning liquid / conductive adhesive / conductive paste / conductive emulsion.

[0113] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
