Description

Technical Field

[0001] The present invention relates to the technical field of cardiac defibrillators, and specifically to a cardiac defibrillator and its usage method. Background Art

[0002] A cardiac defibrillator is a key medical device used to treat severe arrhythmias, especially life-threatening arrhythmias such as ventricular fibrillation and pulseless ventricular tachycardia. Its basic working principle is to restore the normal cardiac rhythm by delivering a certain amount of electrical energy to the heart. In emergency scenarios, the rapid and accurate use of a cardiac defibrillator is crucial for saving the patient's life.

[0003] However, traditional defibrillators usually come with only one set of electrode patches. In emergency situations, continuous defibrillation operations may be required, or the electrode patches may be placed in the wrong position, necessitating the replacement of the patches and restarting the defibrillation. This requires the operator to search for new electrode patches after each use. When installing traditional electrode patches, the data cable often needs to be precisely aligned with a specific interface to ensure normal signal transmission, which increases the installation difficulty and time. Especially in a tense emergency rescue environment, any additional operation steps may cause delays and increase the risk of incorrect operations. Due to the above reasons, both the initial installation and subsequent replacement of electrode patches waste valuable rescue time. In emergency medical situations such as cardiac arrest, every second counts. Reducing unnecessary operation time is decisive for improving the survival rate of patients. Therefore, a cardiac defibrillator and its usage method are needed to solve the above problems. Summary of the Invention

[0017] A method for using a cardiac defibrillator, comprising the following steps:

[0018] Step 1: Turn on the power switch of the defibrillator host, and conduct device operation explanations through the speaker;

[0019] Step 2: Take out the electrode patches, remove the carrier plate from the protective case, and remove the electrode patches on the carrier plate;

[0020] Step 3: Install the electrode patches. According to the patient's physical condition, closely attach the electrode patches to the corresponding positions on the patient's chest to make the electrode patches fit the patient's skin;

[0021] Step 4: Perform defibrillation. Press the defibrillation button. The defibrillator host transmits the energy required for defibrillation to the electrode patches through the cooperation of the first magnetic adsorption electrode and the second magnetic adsorption electrode, and performs cardiac defibrillation on the patient. During the operation, closely monitor the changes in vital signs such as the patient's heart rate on the display screen;

[0022] Step 5: Replace the electrode cartridge. After defibrillation is completed, press the ejection button, the ejection mechanism is activated, the motor drives the turntable to rotate, and through the cooperation of the eccentric rotating shaft and the horizontal chute, the extrusion frame slides downward and inserts into the gap between the electrode cartridge and the defibrillator host, and squeezes the used electrode cartridge at the top towards the outlet until it pops out over the elastic limit strip, and the electrode cartridge below quickly replenishes to the top;

[0023] Step 6: End the operation. After the rescue is over, turn off the power switch, check the number of remaining electrode cartridges in the electrode compartment, and replenish the electrode cartridges in a timely manner.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By arranging a plurality of independent electrode cartridges stacked in the bottom electrode compartment, and cooperating with the ejection mechanism including a motor-driven turntable, an eccentric rotating shaft and an extrusion frame with an arc-shaped spring piece, the present invention solves the problem that traditional single electrode patches cannot be continuously used. When the ejection button is pressed, the motor drives the turntable to rotate, the extrusion frame is pushed horizontally by the eccentric rotating shaft, and the used electrode cartridge is ejected from the outlet by using the arc-shaped spring piece. At the same time, the electrode cartridge below automatically moves up under the action of the compression spring to complete standby replacement. This design realizes the use-and-discard and quick switching of the electrode cartridge in an emergency scenario, avoids the decrease in electrode fitting degree or poor contact caused by repeated use, and greatly shortens the operation interruption time.

[0026] 2. Through the sliding fit between the first guiding chute on the side of the electrode box and the guiding rib in the electrode bin, as well as the limiting plate and elastic limiting strip structure at the top, the present invention ensures that the electrode box only moves along the preset path during the ejection process, preventing shaking or jamming. When the electrode box reaches the top, the first magnetic adsorption electrode and the second magnetic adsorption electrode are automatically adsorbed and conducted, and the cleaning roller is used to dynamically clean the contact surface, and the brush hairs remove the oxide layer or stains. This combined structure not only ensures the physical positioning accuracy during the replacement of the electrode box, but also maintains the stability of the circuit connection through the magnetic adsorption conduction and self-cleaning functions, effectively avoiding the risk of virtual connection in signal transmission.

[0027] 3. The present invention is provided with a pull ring with a torsion spring at the side end of the carrier plate, and in combination with the bevel treatment of the extraction opening, enables the operator to quickly hook the pull ring to extract the electrode box; at the same time, the finger grooves on the carrier plate are correspondingly designed with the lugs of the electrode patch, and combined with the release layer process, realizes the quick peeling of the electrode patch. These detailed designs reduce the operation complexity, reduce the probability of misoperation of the rescue personnel in the high-voltage environment, make the equipment more in line with the ergonomic requirements, and ultimately improve the overall rescue success rate.

[0039] Embodiment 1

[0040] Please refer to Figures 1-10 , a cardiac defibrillator, including a defibrillator main unit 1, several electrode boxes 2 are loaded in the defibrillator main unit 1, and an ejection mechanism 3 cooperating with the electrode box 2 is arranged in the defibrillator main unit 1;

[0041] A display screen 101, a power switch 102, a defibrillation button 103, a speaker 104 and an eject button 105 are arranged on the front end face of the defibrillator main unit 1;

[0042] An electrode compartment 106 is arranged at the bottom of the defibrillator main unit 1, the electrode box 2 is movably installed in the electrode compartment 106, and the electrode box 2 includes a protective shell 201, a carrier plate 202 and an electrode patch 203;

[0043] The ejection mechanism 3 includes an extrusion frame 301, a cleaning roller 302, a motor 303, a turntable 304, a gear 307 and a rack 306, and the ejection mechanism 3 is installed on the top of the electrode compartment 106 for ejecting the electrode box 2 out of the electrode compartment 106.

[0044] By arranging multiple groups of electrode boxes 2 at the bottom of the defibrillator main unit 1, compared with the traditional defibrillator equipped with only one electrode patch, it can continuously perform rescue operations in case of emergency, and can also prevent the user from misoperating and sticking to the wrong part. When uncovering and using again, the insufficient adhesion of the electrode patch may cause poor contact, affecting the rescue success rate. Moreover, the ejection mechanism 3 can quickly eject the used electrode box 2 and replace it with a new electrode box 2, saving precious rescue time during the emergency rescue process.

[0045] Furthermore, the electrode patch 203 is detachably mounted on the carrier plate 202, the carrier plate 202 is movably mounted within the protective housing 201, a first guiding chute 2012 is provided on the side end face of the protective housing 201, a guiding rib 1062 that is slidably engaged with the first guiding chute 2012 is provided on the inner wall side end face of the electrode chamber 106, an extraction opening 107 is provided at the top of the side end face of the electrode chamber 106, a chamber cover 108 fixed by bolts is provided at the bottom of the electrode chamber 106, and a compression spring 1081 is fixedly mounted on the upper end face of the chamber cover 108.

[0046] The compression spring 1081 on the chamber cover 108 pushes the electrode cartridge 2 upward. After the used electrode cartridge 2 is ejected by the ejection mechanism 3, the lower electrode cartridge 2 can quickly reach the top of the electrode chamber 106 for use in the next rescue. Through the cooperation of the first guiding chute 2012 and the guiding rib 1062, the sliding stability of the electrode cartridge 2 is improved, enabling it to displace horizontally only after reaching the top of the electrode chamber 106, thus preventing the electrode cartridge 2 from shaking within the electrode chamber 106.

[0047] Furthermore, a first magnetic adsorption electrode 2011 is provided on the side end face of the protective housing 201, a data line 2031 electrically connected to the first magnetic adsorption electrode 2011 is provided on the electrode patch 203, a second magnetic adsorption electrode 1061 that cooperates with the first magnetic adsorption electrode 2011 is provided at the end of the top of the electrode chamber 106 away from the extraction opening 107, a limiting plate 2014 is provided at the top of the protective housing 201, and an elastic limiting strip 1071 that restricts the sliding of the protective housing 201 is provided on the lower end face of the top of the extraction opening 107.

[0048] When the electrode cartridge 2 slides to the top of the electrode chamber 106 under the action of the compression spring 1081, the protective housing 201 and the defibrillator main unit 1 are automatically adsorbed and docked through the cooperation of the first magnetic adsorption electrode 2011 and the second magnetic adsorption electrode 1061, thereby enabling signal transmission between the electrode patch 203 and the defibrillator main unit 1. The bottom of the elastic limiting strip 1071 is of an arc structure, and the side end face of the limiting plate 2014 is of an inclined plane structure, enabling the protective housing 201 to be firmly engaged with the second magnetic adsorption electrode 1061 under the magnetic adsorption effect and the extrusion of the elastic limiting strip 1071, preventing loose connection.

[0049] Furthermore, a hidden groove 2024 is provided on the side end face of the carrier plate 202, a pull ring 2021 rotatably connected is provided within the hidden groove 2024, a torsion spring 2022 is provided on the pull ring 2021, the pull ring 2021 and the carrier plate 202 are elastically rotatably connected through the torsion spring 2022, and chamfering is performed on the top and bottom of the extraction opening 107.

[0050] A pull ring 2021 is provided on the side end face of the carrier plate 202, which facilitates quickly pulling out the carrier plate 202. When the electrode box 2 reaches the extraction opening 107, under the action of the torsion spring 2022, the pull ring 2021 automatically unfolds outward to the horizontal. By chamfering the edge of the extraction opening 107, the hand operation space is increased, facilitating quickly grasping the pull ring 2021 and quickly taking out the carrier plate 202.

[0051] Further, pulley wheels 2013 are evenly arranged on the upper end face of the protective shell 201 in a rotatably connected manner.

[0052] By means of the pulley wheels 2013, the friction between the protective shell 201 and the defibrillator main unit 1 and the lower electrode box 2 is reduced. Thus, when the ejecting mechanism 3 ejects the protective shell 201, the electrode box 2 can be ejected from the extraction opening 107 as directly as possible, reducing manual intervention.

[0053] Further, finger grooves 2023 are arranged at the edge of the upper end face of the carrier plate 202, and ear tabs 2032 corresponding to the positions of the finger grooves 2023 are arranged on the electrode patch 203.

[0054] An isolation layer is arranged on the carrier plate 202. The electrode patch 203 is attached to the carrier plate 202. By arranging the finger grooves 2023 on the carrier plate 202 and aligning the ear tabs 2032 of the electrode patch 203 with the finger grooves 2023, the electrode patch 203 can be conveniently and quickly peeled off from the carrier plate 202, improving the convenience of taking the electrode patch 203 and saving valuable rescue time.

[0055] Further, the motor 303 is fixedly installed on the inner wall side end face of the electrode bin 106, the turntable 304 is fixedly installed on the output shaft of the motor 303, an eccentric rotating shaft 3041 is arranged on the front end face of the turntable 304, and a transverse sliding groove 3012 which is slidably matched with the eccentric rotating shaft 3041 is arranged on the side end face of the extrusion frame 301.

[0056] The motor 303 drives the turntable 304 to rotate, so that the turntable 304 drives the eccentric rotating shaft 3041 to rotate around the output shaft of the motor 303, thereby generating a longitudinal displacement difference, driving the extrusion frame 301 to slide downward, inserting into the gap between the electrode box 2 and the defibrillator main unit 1, and extruding the electrode box 2 towards the extraction opening 107 until the electrode box 2 crosses the elastic limiting strip 1071 and pops out of the defibrillator main unit 1.

[0057] Further, an arc-shaped spring piece 3011 is arranged at the end of the extrusion frame 301 close to the electrode box 2, a guide plate 3013 is arranged at the top of the extrusion frame 301, and a second guide sliding groove 1063 which is slidably matched with the guide plate 3013 is arranged at the top of the electrode bin 106.

[0058] The electrode cartridge 2 is extruded by the arc-shaped spring piece 3011, enabling it to generate elastic deformation during the extrusion process and store elastic potential energy. When the pressure is large enough, it forces the electrode cartridge 2 to cross the elastic limit strip 1071, and the arc-shaped spring piece 3011 releases the elastic potential energy, which is converted into the kinetic energy of the electrode cartridge 2, causing it to pop out quickly.

[0059] Furthermore, the cleaning roller 302 is installed on the extrusion frame 301 and rotatably connected thereto. Brush hairs 3021 are evenly arranged on the surface of the cleaning roller 302. A gear 307 is fixedly installed on the cleaning roller 302, and a rack 306 meshing with the gear 307 is fixedly installed on the inner end surface of the side wall of the electrode chamber 106.

[0060] When the extrusion frame 301 drives the cleaning roller 302 to slide downward, the cleaning roller 302 is driven to rotate by itself through the cooperation of the gear 307 and the rack 306, so that the brush hairs 3021 on the surface of the cleaning roller 302 brush the second magnetic attraction electrode 1061, avoiding stains adhering to the surface of the second magnetic attraction electrode 1061, and rust and oxide layers can be brushed off by the steel brush hairs 3021, maintaining the conductivity of the first magnetic attraction electrode 2011 and the second magnetic attraction electrode 1061.

[0061] Embodiment 2

[0062] Please refer to Figures 1-10 , a method for using a cardiac defibrillator, including the following steps:

[0063] Step 1: Turn on the power switch 102 of the defibrillator main unit 1. At this time, the defibrillator starts self-checking to confirm that all functional modules of the device are operating normally. At the same time, the speaker 104 automatically turns on, and gives an explanation of the device operation in clear and standard voice, covering the basic functions of the defibrillator, the uses of each component, the key steps and precautions in the next operation process, to ensure that the operator can accurately understand the subsequent operation requirements;

[0064] Step 2: Take out the electrode patch 203. The operator quickly horizontally pulls out the carrier plate 202 from the protective case 201 after taking it out. The pulling process should be stable and rapid. Subsequently, pinch the ear 2032 at the edge of the electrode patch 203 and carefully remove it from the carrier plate 202, taking care not to touch the conductive surface of the electrode patch 203 to avoid contamination and affecting the conductive performance;

[0065] Step 3, install the electrode patch 203, accurately determine the fitting position of the electrode patch 203 according to the patient's physical condition, for adult patients, generally one electrode patch 203 is attached below the patient's right clavicle, and the other is attached to the outside of the left nipple, and the center of the electrode patch 203 is about 2.5-5 cm away from the nipple; for children, the position of the electrode patch 203 can be adjusted appropriately, one is placed on the upper right side of the chest, and the other is placed on the fifth intercostal space of the left anterior axillary line, and the electrode patch 203 is tightly attached to the corresponding position of the patient's chest, and gently pressed to ensure that the electrode patch 203 is completely fitted to the patient's skin without bubbles or wrinkles, so as to ensure good conductivity;

[0066] Step 4, implement defibrillation. Before pressing the defibrillation button 103, the operator needs to confirm again that the electrode patch 203 is correctly positioned and fits tightly, and loudly remind the surrounding personnel not to touch the patient and the bed to avoid the current during defibrillation causing harm to others. After pressing the defibrillation button 103, the internal circuit of the defibrillator host 1 is quickly turned on, and the preset energy required for defibrillation is stably and quickly transmitted to the electrode patch 203 through the cooperation of the first magnetic electrode 2011 and the second magnetic electrode 1061. The electrode patch 203 then releases the energy to the patient's heart to stimulate the heart to restore normal rhythm. During the operation, the operator should pay close attention to the changes in the patient's heart rate, pulse and other vital signs on the display screen 101;

[0067] Step 5, replace the electrode cartridge 2. After defibrillation is completed, if it is necessary to continue the defibrillation operation or prepare for the next possible defibrillation demand, the operator needs to press the ejection button 105. At this time, the ejection mechanism 3 is started, the motor 303 is powered on, and the turntable 304 is driven to rotate for one circle. The eccentric shaft 3041 on the front end surface of the turntable 304 then makes a circular motion around the output shaft of the motor 303. Through the sliding cooperation with the transverse slide groove 3012 on the side end surface of the extrusion rack 301, the extrusion rack 301 is caused to slide downward and accurately insert into the gap between the electrode cartridge 2 and the defibrillator host 1. The extrusion rack 301 is continuously squeezed downward to push the electrode cartridge 2 located at the top after use toward the removal port 107. Under the action of the squeezing force, the electrode cartridge 2 overcomes the resistance of the elastic limit strip 1071, passes over the limit strip and ejects the defibrillator host 1. At the same time, the electrode cartridge 2 below is quickly moved upward to the top under the action of the compression spring 1081 on the compartment cover 108, so as to be ready for the next use.

[0068] Step 6, End operation. After the rescue is over, the operator first turns off the power switch 102 to stop the defibrillator from working. Subsequently, open the electrode compartment 106 and carefully check the number of remaining electrode cartridges 2 in the electrode compartment 106. If the remaining quantity is insufficient, new electrode cartridges 2 need to be replenished in a timely manner according to the specified procedure to ensure that the defibrillator can operate normally during the next use. At the same time, conduct an external inspection of the defibrillator main unit 1 to check for any damage or stains. If there are stains, gently wipe them clean with a clean and soft damp cloth. Finally, place the defibrillator properly in the specified storage location and make a record of the equipment usage.

[0069] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

10. A method for using a cardiac defibrillator, applicable to a cardiac defibrillator as described in any one of the above claims 1-9, characterized in that, It includes the following steps: Step 1: Turn on the power switch (102) of the defibrillator host (1), and give an operation explanation of the device through the speaker (104). Step 2: Take out the electrode patch (203), take out the carrier plate (202) from the protective shell (201), and remove the electrode patch (203) on the carrier plate (202). Step 3: Install the electrode patch (203). According to the patient's physical condition, attach the electrode patch (203) to the corresponding position on the patient's chest to make the electrode patch (203) fit the patient's skin. Step 4: Perform defibrillation. Press the defibrillation button (103). The defibrillator host (1) transmits the energy required for defibrillation to the electrode patch (203) through the cooperation of the first magnetic attraction electrode (2011) and the second magnetic attraction electrode (1061) to perform a cardiac defibrillation operation on the patient. Step 5: Replace the electrode box (2). After defibrillation is completed, press the ejection button (105), and the ejection mechanism (3) is activated to extrude the used electrode box (2) at the top outward until it ejects from the defibrillator host (1), and the electrode box (2) below is replenished to the top. Step 6: End the operation. After the rescue is over, turn off the power switch (102), check the number of remaining electrode boxes (2) in the electrode chamber (106), and replenish the electrode box (2) in time.
