Description

Technical Field

[0001] This utility model relates to surgical instruments for electrotherapy, magnetotherapy or ultrasound therapy, and specifically to an electrode patch device and a defibrillator for animal cardiopulmonary resuscitation. Background Technology

[0002] Cardiac arrest refers to the sudden cessation of the heart's pumping function, the disappearance of large artery pulsation and heart sounds, and severe ischemia and hypoxia in vital organs such as the brain and heart, leading to death. Defibrillation, which requires selecting effective energy and generating sufficient current through the defibrillator to remove ventricular fibrillation and restore sinus rhythm, remains the only effective method for treating patients with ventricular fibrillation.

[0003] In animal experiments, the main animal models used for cardiac arrest resuscitation are dogs, pigs, rabbits, and rats. Defibrillators are typically used for cardiopulmonary resuscitation. Defibrillators are generally equipped with a defibrillator handle, but this handle is usually designed to fit the human body. The handle is relatively large compared to the animal, so in animal (e.g., rat) defibrillation experiments, the bottom of the handle does not easily fit the animal, leading to defibrillation failure. While using a smaller handle reduces the size of the bottom, in actual use, the rest of the handle can easily touch the animal, causing leakage or short circuits, also leading to defibrillation failure. Furthermore, the large size of the handle makes transportation difficult. Therefore, a miniaturized defibrillation device suitable for animal defibrillation is needed. Utility Model Content

[0004] The electrode patch device and defibrillator of this invention for animal cardiopulmonary resuscitation can effectively solve the problem that the electric shock handle is not conducive to defibrillation in animals in the prior art.

[0005] According to one aspect of the present invention, an electrode patch device for animal cardiopulmonary resuscitation is provided, comprising:

[0006] Electrode plates;

[0007] An insulating sheet, connected to the electrode sheet, is used to cover the electrode sheet;

[0008] An insulated handle is provided for a wire to pass through after being energized. The insulated handle has a conductive end embedded between the electrode plate and the insulating plate. The wire is electrically connected to the electrode plate through the conductive end.

[0009] In some embodiments, the conductive end is provided with a conductive plate electrically connected to the wire, the conductive plate abutting against the electrode plate to electrically connect the electrode plate, and the conductive plate covering the wire. Thus, the electrode plate facilitates the uniform transfer of power to the electrode plate, avoids direct contact between the wire and the electrode plate, and prevents wire leakage.

[0010] In some embodiments, the electrode sheet has an electrode groove, and the conductive end drives the conductive sheet to move along the electrode groove. The conductive sheet is positioned and electrically connected to the electrode sheet through the electrode groove. Therefore, the electrode groove facilitates the positioning of the conductive sheet, preventing excessive movement of the conductive end or even detachment from the electrode sheet, resulting in a more compact fixation of the conductive end.

[0011] In some embodiments, a connecting assembly is also included, which passes through the conductive end and is detachably connected to the electrode plate and the insulating plate to secure the insulating handle. Thus, the connecting assembly further secures the insulating handle, which can be detachably connected to the electrode plate and the insulating plate for easy replacement.

[0012] In some embodiments, the conductive end has a connection hole, and the connection assembly includes:

[0013] An insert having a connecting post and a pressure plate;

[0014] A locking member having a socket for connection with the connecting post;

[0015] The connecting post passes through the electrode plate and the insulating plate and is inserted into the connecting hole. The pressure plate abuts against the electrode plate. The locking member is detachably connected to the connecting post to press against the insulating plate. Thus, the conductive end is limited on the electrode plate by the insert and locked by the locking member.

[0016] In some embodiments, the connecting column is provided with a limiting portion, and the locking member is provided with a locking portion. The locking member moves along the connecting column through the insertion hole, causing the locking portion to engage with the limiting portion to fix the conductive end between the electrode sheet and the insulating sheet. Thus, the locking member and the insert are detachably connected by the engagement of the limiting portion and the locking portion.

[0017] In some embodiments, the connecting assembly further includes an elastic washer disposed between the insulating sheet and the locking member, which deforms under force when the locking member is detachably connected to the connecting post. Thus, the elastic washer helps to provide elastic force when pressing the insulating sheet, resulting in a tighter fit between the insert and the locking member, making it less prone to detachment.

[0018] In some embodiments, the electrode sheet has a recessed groove, and when the locking member is detachably connected to the connecting column, the pressure plate abuts against the recessed groove. This helps to confine the pressure plate within the recessed groove, minimizing the impact on the conductivity of the electrode sheet.

[0019] In some embodiments, the pressure plate is provided with a conductive portion that passes through the recessed groove and makes conductive contact with the conductive sheet, thereby electrically connecting the pressure plate to the electrode sheet. This conductive portion facilitates more uniform conductivity of the electrode sheet.

[0020] On the other hand, a defibrillator for animal cardiopulmonary resuscitation is provided, including the above-mentioned electrode patch device for animal cardiopulmonary resuscitation and an electrocardiogram monitoring device, wherein one end of the lead wire is provided with a first connector and the electrocardiogram monitoring device is provided with a second connector, and the first connector and the second connector are detachably connected to allow the lead wire to be energized.

[0021] The electrode patch device and defibrillator of this invention for animal cardiopulmonary resuscitation have the following advantages compared with the prior art:

[0022] This application simplifies the structure of the defibrillation handpiece by embedding an insulating handle with electrode pads and insulating sheets, and energizing the electrode pads by passing wires through the insulating handle. The electrode pads are smaller in size, can better adapt to the animal's body shape and fit the animal's contact surface, and are easier to store and transport. The insulating handle and insulating sheets help to avoid leakage during use. In comparison, defibrillation with electrode pads can output electrotherapy parameters that are more consistent with the animal, thereby improving the efficiency of high-quality cardiopulmonary resuscitation and the success rate of model establishment in experimental animals.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] This utility model relates to an electrode patch device for animal cardiopulmonary resuscitation, which is suitable for animal cardiac arrest resuscitation. It can be electrically connected to defibrillation equipment or electrocardiogram monitoring equipment. It is small in size and has good insulation performance, which is conducive to miniaturization of existing electric shock handles.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings.

[0038] Figure 1 An electrode patch device for animal cardiopulmonary resuscitation according to one embodiment of the present invention is schematically shown. Figure 1 As shown, the electrode patch device for animal cardiopulmonary resuscitation includes an electrode patch 1, an insulating patch 2, and an insulating handle 3.

[0039] like Figure 1 , Figure 3 As shown, electrode pad 1 can be a conventional medical device electrode patch. Electrode pad 1 transmits specific electrical signals to the human body through its conductive material to achieve therapeutic or monitoring effects. Electrode pad 1 generally has a backing layer to provide support, protect the conductive material, and ensure that the electrode patch is not easily deformed during use. Electrode pad 1 also has an adhesive to firmly adhere to the skin and prevent it from falling off during use. Insulating sheet 2 is connected to electrode pad 1, mainly through conductive gel adhesion. Insulating sheet 2 is specifically adhered to the edge of electrode pad 1 to form a surrounding effect. Insulating sheet 2 can cover electrode pad 1 to protect electrode pad 1 from affecting conductivity. Insulating sheet 2 also has the effect of isolating leakage current on the other side of electrode pad 1 to protect the user. The material of insulating sheet 2 is rubber, silicone, or PE, PP, etc. Preferably, electrode pad 1 and insulating sheet 2 have the same size, with the length d ranging from 4cm to 4.5cm and the width w ranging from 3.5cm to 4cm. Preferably, the length d is 4.3cm and the width w is 3.8cm to better suit the body size of rats. Optionally, the insulating sheet 2 is marked with colored markings to distinguish the use side of the electrode sheet 1 or the insulating sheet 2.

[0040] An insulating handle 3 is connected between the electrode pad 1 and the insulating sheet 2. The insulating handle 3 is for manual operation by medical personnel and is preferably made of plastic. It has a rod-shaped design and a through-hole structure for the passage of a lead wire 5. The lead wire 5 can be electrically connected to the electrode pad 1. The other end of the lead wire 5 is connected to an external defibrillator or ECG monitoring device 6 so that the lead wire 5 can be energized. The lead wire 5 can pass through the insulating handle 3 and connect to the electrode pad 1, effectively preventing leakage. Optionally, an insulating layer is provided on the outside of the insulating handle 3 to further enhance the insulation effect. The end of the insulating handle 3 is a conductive end 31. The lead wire 5 extends from the conductive end 31 to connect to the electrode pad 1. The conductive end 31 is embedded between the electrode pad 1 and the insulating sheet 2, allowing the conductive end 31 to be electrically connected to the electrode pad 1. The user can control the movement of the electrode pad 1 by operating the insulating handle 3, which also enhances the insulation performance.

[0041] In some implementations, such as Figure 2As shown, the insulating handle 3 has a bent or curved shape, which makes the insulating handle 3 form a handhold part 32 and a bent part 33. The insulating handle 3 has a "Z" shaped shape. The handhold part 32 and the bent part 33 have a height difference. The bent part 33 is integrally formed with the conductive end 31. When in use, the bent part 33 is closer to the surface of the animal, and the handle part can keep as far away from the surface of the animal as possible, so as to improve the ease of use of the insulating handle 3.

[0042] Furthermore, such as Figure 3 As shown, to improve the conductivity of the electrode plate 1, a conductive sheet 34 electrically connected to the wire 5 is provided at the conductive end 31. The conductive sheet 34 is made of metal to improve conductivity. The conductive sheet 34 is attached to the bottom surface of the conductive end 31, and the surface area of ​​the conductive sheet 34 is equal to the bottom area of ​​the conductive end 31, making the wire 5 conduct electricity more evenly. The conductive sheet 34 directly contacts the electrode plate 1 and covers the end of the wire 5, so that the end of the wire 5 is hidden in the insulating handle 3, thus making the structure more compact. Furthermore, an electrode groove 11 is provided on the electrode plate 1. The electrode groove 11 adopts a recessed opening groove structure, so that the side of the electrode plate 1 is an open structure. The conductive end 31 can drive the conductive sheet 34 to move along the electrode groove 11 to install the conductive sheet 34. The electrode groove 11 can also limit the conductive sheet 34, making it difficult for the conductive end 31 to move or slip. Therefore, the conductive sheet 34 can be positioned in the electrode groove 11.

[0043] like Figure 10 As shown, this application also provides a defibrillator for animal cardiopulmonary resuscitation, including the above-mentioned electrode patch device for animal cardiopulmonary resuscitation and an electrocardiogram monitoring device 6 or a defibrillator. One end of the lead wire 5 is provided with a first connector 51, and the electrocardiogram monitoring device 6 is provided with a second connector 61. The connectors can adopt the structure of a conventional USB plug or socket. The first connector 51 and the second connector 61 can be detachably connected so that they can be electrically connected to the electrode patch 1 after being energized.

[0044] When in use, the energized electrode 1 is attached to the animal's surface by holding the insulated handle 3. Usually, two insulated handles 3 with electrode 1 are needed, one positive and one negative, and then normal cardiopulmonary resuscitation is performed on the animal.

[0045] In some embodiments, such as Figure 4 As shown, a structure with replaceable electrode pad 1 and insulating pad 2 is provided to facilitate later replacement and use. The electrode patch device for animal cardiopulmonary resuscitation also includes a connecting component 7. The insulating handle 3 with conductive pad 34 can be detached from the electrode pad 1 when pulled forcefully and can be reinforced by the connecting component 7. The connecting component 7 can pass through the conductive end 31 and be detachably connected to the electrode pad 1 and the insulating pad 2, so that the insulating handle 3 is fixed between the electrode pad 1 and the insulating pad 2.

[0046] like Figure 5 , Figure 6 As shown, the connecting assembly 7 includes an insert 71, a locking member 72, and an elastic gasket 73. The insert 71 has a rod-shaped structure and can pass through the electrode plate 1, the insulating plate 2, and the insulating handle 3 through the shaft hole structure. The electrode plate 1 and the insulating plate 2 have corresponding through holes. The conductive end 31 has a connecting hole 311, which also passes through the conductive plate 34. The connecting hole 311 is also a through hole structure. The insert 71 has a connecting post 711 and a pressing plate 712. The connecting post 711 can be inserted into the connecting hole 311. The pressing plate 712 is connected to the bottom end of the connecting post 711 and can abut against the electrode plate 1. Furthermore, the electrode plate 1 is provided with a recessed groove 12. The recessed groove 12 has a groove structure and is adapted to the size of the pressing plate 712. The pressing plate 712 can abut against the recessed groove 12 so that the pressing plate 712 does not protrude from the electrode plate 1. The locking member 72 is used to cooperate with the insert 71 so that the conductive end 31 can be pressed and fixed. The locking member 72 can be made of plastic. When in use, the locking member 72 is located on one side of the insulating sheet 2. The locking member 72 adopts a ring structure with a socket 722 in the center. The socket 722 is a through hole structure. The locking member 72 is inserted into the connecting post 711 through the socket 722 and can be detachably connected to the connecting post 711 so that the electrode sheet 1 and the insulating sheet 2 can be pressed together.

[0047] Specifically, such as Figures 6-9 As shown, the connecting column 711 is provided with a limiting part 714, which protrudes from the side of the connecting column 711 and has a certain deformation capability. The limiting part 714 has an inclined surface along the side near the pressure plate 712. The locking member 72 is provided with a locking part 721, which is connected to the insertion hole 722. The locking part 721 adopts a groove structure, and the hole wall of the insertion hole 722 is provided with an inclined surface structure that slides with the limiting part 714. When the locking member 72 moves along the connecting column 711, the locking member 72 gradually locks along the inclined surface of the limiting part 714, and finally the limiting part 714 is engaged in the locking part 721, so that the connecting column 711 and the locking member 72 are engaged. The elastic gasket 73 is made of an insulating elastic material, such as silicone or rubber. The elastic gasket 73 has a through-hole structure and can be inserted into the connecting post 711. The elastic gasket 73 can provide the necessary elastic force when the locking member 72 is engaged, so that the locking member 72 and the connecting post 711 are engaged more tightly.

[0048] Optional, such as Figure 7 , Figure 8As shown, the pressure plate 712 is provided with a conductive part 713, which is an annular structure protruding along the direction of the connecting post 711. The pressure plate 712 and the conductive part 713 are made of conductive materials, such as conductive plastic or metal, or the same material as the electrode sheet 1. The connecting post 711 is made of insulating material. When the pressure plate 712 abuts against the edge of the recessed groove 12, the conductive part 713 can pass through the recessed groove 12 and abut against the conductive sheet 34 to form a contact conductivity and transmit it to the pressure plate 712. The pressure plate 712 then transmits the power to the electrode sheet 1 to achieve electrical connection, so that the pressure plate 712 can conduct electricity and increases the conductivity of the electrode sheet 1.

[0049] In use, the elastic washer 73 is inserted between the insulating sheet 2 and the locking member 72, and then the locking member 72 is gradually engaged with the connecting post 711, so that the pressure plate 712 can tightly abut against the electrode sheet 1. The locking member 72 and the connecting post 711 are engaged through the cooperation of the limiting part 714 and the engaging part 721. The elastic washer 73 provides elasticity to the locking member 72, so that the locking member 72 can maintain its engagement with the connecting post 711, while also helping to protect the shape of the insulating sheet 2 and the electrode sheet 1. When disassembly and replacement are required, simply press the limiting part 714 to disengage the locking member 72 from the connecting post 711.

[0050] The above description is merely a preferred embodiment of the present utility model. To simplify the description, not all possible combinations of the various technical features in the above embodiments have been described, and this is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
