Example 1
Referring to fig. 1-11, a disposable electrode structure 100 of a defibrillator according to a first embodiment of the present invention includes a pole assembly 110 and a pole assembly 120, the pole assembly 110 includes a base 111 and a pole member 112, the pole member 112 is sleeved in the base 111, and the pole member 112 is formed with a jack 1121; the pole inserting assembly 120 comprises a plug body 121, a pole inserting piece 122 and a limiting ring 123, the pole inserting piece 122 is sleeved in the plug body 121, the pole inserting piece 122 comprises a wire body 1221 and an elastic deformation end 1222 connected with the wire body 1221, the elastic deformation end 1222 stretches out and draws back along the radial direction, the limiting ring 123 is sleeved on the elastic deformation end 1222 and is used for limiting the elastic deformation end 1222 to expand along the radial direction, so that the elastic deformation end 1222 is spliced in the jack 1121; when the elastically deformed end 1222 is inserted into the insertion hole 1121, the limiting ring 123 is pushed by the pole piece 112 in the axial direction of the wire body 1221, so that the limiting ring 123 releases the limitation of the elastically deformed end 1222, and when the elastically deformed end 1222 is inserted into the insertion hole 1121 to be pulled out of the insertion hole 1121, the elastically deformed end 1222 expands in the radial direction, so as to limit the pole piece 122 from being repeatedly inserted into the pole piece 112. In particular applications, a transient high energy pulse is applied to the heart during defibrillation, typically for a duration of 4 to 10ms and with an electrical energy of 40 to 400J (joules). Devices for defibrillation of a heart are known as defibrillators, which are capable of performing electrical shock cardioversion, i.e., defibrillation. When a patient develops severe tachyarrhythmias, such as atrial flutter, atrial fibrillation, supraventricular or ventricular tachycardia, etc., various degrees of hemodynamic dysfunction are often caused. Particularly when the patient has ventricular fibrillation, the heart is shot and blood circulation is stopped because the ventricles have no integral contraction capacity, and if the patient is not rescued in time, the patient is often dead due to the overlong cerebral hypoxia time. If a defibrillator is adopted, a certain energy current is controlled to pass through the heart, so that certain arrhythmia can be eliminated, and the heart rhythm can be recovered to be normal, thereby rescuing and treating the heart disease patient. However, the existing plugs of the electrode pads of the defibrillator 10 on the market are basically reusable plugs, so that certain people or mechanisms cannot avoid the repeated use of the electrode pads in order to save cost, the electrode pads are generally disposable products, if the repeated use is performed, the defibrillation effect is greatly reduced, the special structure is designed to solve the problem that the electrode pads in the defibrillator 10 are repeatedly used in critical time, in particular, the elastic deformation end 1222 is arranged at the tail end of the electrode pads 122, the elastic deformation end 1222 can elastically stretch in the radial direction, when the electrode pads 122 are not inserted into the jack 1121 of the electrode pads 112, at this time, the electrode pads connected to one end of the electrode pads 122 are not used, and the limiting ring 123 is sleeved on the elastic deformation end 1222 to limit the elastic deformation end 1222 to expand in the radial direction, so that the elastic deformation end 1222 can be inserted into the jack 1121, and the limiting ring 1222 is inserted into the jack 1121, in the process that the limiting ring 123 pushes the limiting ring 123 towards the electrode pads 112, and the electrode pads 122 are completely connected to the electrode pads 112 in the axial direction of the electrode pads 112, and the current can be completely deformed to the electrode pads 112, when the electrode pads 122 are completely connected to the electrode pads 112, the electrode pads 122 are completely and the electrode pads 112 are completely deformed to the electrode pads 112, the electrode pads 122 can be completely deformed to the electrode pads 112 are completely and the electrode pads are completely deformed when the electrode pads 122 are connected to the electrode pads 112, and the electrode pads are completely deformed to the electrode pads are electrically, and the electrode pads are electrically conductive, the electrode sheet after use is pulled out of the electrode connector 112 together with the electrode connector 122, and at this time, the elastically deformed end 1222 is elastically deformed along the radial direction, so that the electrode connector 122 cannot be repeatedly inserted into the electrode connector 112, and thus, the repeated use of the electrode sheet is avoided from the physical structure, thereby improving the defibrillation effect and reducing the risk of the rescued object.
In one possible embodiment, the elastically deformable end 1222 includes petals 12221, at least two petals 12221 are disposed around the space and connected to one end of the wire 1221, when the stop collar 123 is sleeved outside the petals 12221, the petals 12221 are compressed and closed by the stop collar 123 to allow the petals 12221 to be inserted into the insertion hole 1121, and when the stop collar 123 is pushed away from the petals 12221 by the connector 112, the petals 12221 expand radially to a diameter greater than the diameter of the insertion hole 1121 to limit insertion of the petals 12221 into the insertion hole 1121. In a specific application, one end of the petal 12221 is connected to the wire 1221, the outer side of the other end of the petal 12221 is compressed and closed by the limiting ring 123, and because the limiting ring 123 is elastically and outwardly tensioned by the petal 12221, the limiting ring 123 is kept on the petal 12221, and meanwhile, the diameter of the compressed petal 12221 is smaller than that of the jack 1121, so that the petal 12221 can be inserted into the jack 1121, when the limiting ring 123 is pushed away from the constraint end of the petal 12221 by the pole piece 112, the petal 12221 gradually expands in the radial direction, so that the diameter of the petal 12221 is equal to that of the jack 1121, and the petal 12221 is elastically abutted against the inner wall of the jack 1121, thus, after the force applied by the pole piece 122 is removed, the pole piece 122 can still be tightly connected with the pole piece 112, and the electrical contact between the pole piece 122 and the pole piece 112 is improved; when the petal 12221 is pulled out of the insertion hole 1121, the petal 12221 is deformed under natural elastic recovery, so that the diameter of the petal 12221 is larger than that of the insertion hole 1121, and the connector cannot be repeatedly inserted into the connector 112.
In one possible embodiment, the petal 12221 includes a base 12201, a middle 12202, a top 12203, and a boss 12204, the base 12201 is connected to the wire 1221, the middle 12202 is connected between the base 12201 and the top 12203, the boss 12204 protrudes radially from the middle 12202, the stop collar 123 is sleeved between the middle 12202 and the top 12203, and the stop collar 123 is elastically isolated from the base 12201 by the boss 12204. In a specific application, the petal-shaped body 12221 includes a base 12201, a middle 12202, a top 12203 and a boss 12204, the base 12201 is connected to the wire 1221, the radial deformability is minimum, the top 12203 is far away from the base 12201, the middle 12202 is connected between the base 12201 and the top 12203, and the radial deformability is between the two, wherein the boss 12204 is radially protruding on the middle 12202, and the stop ring 123 is sleeved between the middle 12202 and the top 12203, so that the petal-shaped body 12221 can be restrained from being radially expanded and deformed, the petal-shaped body 12221 can be elastically expanded and restrained from being accidentally separated from the stop ring 123, and the boss 12204 is arranged on the middle 12202, so that the stop ring 123 cannot enter the base 12201 without external force, and thus the influence of the accidental opening of the petal-shaped body 12221 on normal use is avoided.
