Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an electrocardiograph lead electrode sheet for emergency use. Background Art

[0002] The electrocardiograph is an important device for monitoring and recording heart function. Its medical principle is to transmit the electrocardiogram vectors generated during the depolarization and repolarization of the heart to various parts of the body through volume conduction, and generate a potential difference. The electrodes are positioned and fixed on the human skin and connected to the electrocardiograph through a conductive wire bundle to automatically draw an electrocardiogram. The conductive wire bundle that places the electrodes and is connected to the electrocardiograph is called an electrocardiogram lead.

[0003] In clinical practice, an electrocardiograph is often needed for some critically ill patients or heart disease patients. The electrocardiograph can monitor and record the patient's electrocardiogram in real time, and is mainly composed of lead wires and electrodes. Most of the existing electrocardiograph electrodes are fixed to the designated position on the patient's skin surface by adhesive sheets, and then the lead wires are connected to the electrodes, so as to continuously monitor the patient's physiological parameters and provide a basis for doctors to deal with emergencies and treatment.

[0004] Traditional technology uses a self-healing rubber balloon connected to a metal suction cup and used in conjunction with it. The rubber balloon is pressed to exhaust air. While the rubber balloon self-recovers, the metal suction cup forms a negative pressure and is adsorbed on the patient's epidermis. A set of buckles are set on both sides of the metal suction cup to clip on the external lead harness. Its disadvantages are: large size and heavy weight, which are not suitable for patients with dry skin or thin bodies, and are easily dropped due to external interference, resulting in a poor treatment experience.

[0005] In order to further improve and solve the above problems and ensure the accuracy of the electrode transmission signal monitoring, the existing technology uses thin electrode sheets. When sticking electrode sheets on patients in relatively dry seasons, it is necessary to first apply conductive liquid to the patient's skin surface to promote the conductivity of the skin, so that the electrophysiology of the heart can be more accurately fed back to the electrocardiograph. After applying the conductive liquid on the skin surface, multiple electrode sheets are transferred to the designated positions, and then the electrode sheets are connected to the lead wires. They are light in weight and not easily dropped due to structural interference.

[0006] For existing thin electrode sheets, because the electrode sheets are attached to the skin surface for a long time, the conductive liquid applied between the electrode sheets and the skin is easy to evaporate, affecting the conductivity of the skin, resulting in inaccurate ECG data monitored, collected and recorded, so it is necessary to add conductive liquid intermittently. Because the ECG of emergency patients has high requirements for accuracy and timeliness, if the conductive liquid is added temporarily after the ECG machine is turned off or in the middle, for emergency patients, inaccurate ECG signal recording may occur, resulting in later medical diagnosis errors, so the electrode sheets cannot be repeatedly uncovered to add conductive liquid. Therefore, the operation is more troublesome.

[0007] In addition, since the lead electrodes must be attached to the skin surface of the patient's chest or abdomen, on the one hand, the patient's breathing will cause local fluctuations, causing the lead electrodes to slip off. On the other hand, for elderly patients, thin patients, and patients with dry skin, the lead electrodes will not have sufficient contact with the skin, making them more likely to fall off, resulting in structural instability. All of the above will increase the interference waves and artifacts of the ECG machine, resulting in inaccurate ECG signal recording.

[0008] Therefore, it is urgent to design an emergency electrocardiograph lead electrode sheet that has good fixing effect, is not easy to fall off, has strong adhesion, good air permeability, and is conducive to efficient clinical use. Utility Model Content

[0009] In view of the problems existing in the prior art, the utility model provides an emergency electrocardiograph lead electrode sheet. After adopting the emergency electrocardiograph lead electrode sheet, on the one hand, through the design of the first conductive gel layer and the second conductive gel layer, the conductive gel layer is not easy to volatilize, has good conductivity and adhesion, is soft in material, has good hydrophilicity, does not irritate the skin, has moderate viscosity, and has long-lasting viscosity, so that the lead electrode sheet can be better attached to the patient's skin without affecting the conductivity of the skin, so that the electrophysiology of the heart can be more accurately fed back to the electrocardiograph;

[0010] On the other hand, a conductive elastic member is connected to the side of the first conductive gel layer away from the supporting layer. The conductive elastic member can shrink when under pressure and recover when not under pressure. When the patient's breathing causes local fluctuations, or for elderly patients, thin patients and patients with dry skin, the lead electrode sheet can fully adapt to the skin contact part to ensure that the second conductive gel layer on the conductive elastic member can fully contact the skin contact part, improve the stability of the conductive signal, and avoid large interference waves and artifacts in the electrocardiograph, which makes the electrocardiograph record inaccurate.

[0011] In addition, an adhesive layer is provided on the outer edge of the first conductive gel layer, with the help of which the lead electrode sheet can be fixed to the patient's skin. A lead interface is provided in the circumferential direction of the conductive ball head, and the lead interface is connected to the external lead harness. This applies vertical pressure to the top of the center position of the lead electrode sheet, which can further increase the pressure of the lead electrode sheet on the skin contact part, making it more firmly and tightly bonded to the skin and not easy to slip off, thereby avoiding the problem of the lead electrode sheet being easy to slip due to the eccentric connection of the lead electrode sheet, which generates a large eccentric force.

[0012] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0013] The present application proposes an emergency electrocardiograph lead electrode sheet, comprising:

[0014] A conductive ball head, wherein the conductive ball head is provided with a lead interface in the circumferential direction, and the lead interface is used to connect with an external lead harness;

[0015] A support layer, wherein the support layer is provided with a through hole, and the through hole accommodates the upper end of the conductive ball head to pass through;

[0016] a first conductive gel layer connected to the support layer, wherein a T-shaped limiting hole is provided inside the first conductive gel layer, the lower end of the conductive ball head is buried in the T-shaped limiting hole, and an adhesive layer is provided on the outer edge of the first conductive gel layer;

[0017] A conductive elastic member connected to a side of the first conductive gel layer away from the support layer, wherein the conductive elastic member can shrink when under pressure and can self-recover when not under pressure;

[0018] a second conductive gel layer connected to a side of the conductive elastic member away from the first conductive gel layer;

[0019] The design of the above technical solution, on the one hand, through the design of the first conductive gel layer and the second conductive gel layer, the conductive gel layer is not easy to volatilize, has good conductivity and adhesion, and is soft, so that the lead electrode sheet can be better attached to the patient's skin without affecting the conductivity of the skin, thereby enabling the electrophysiology of the heart to be more accurately fed back to the electrocardiograph;

[0020] On the other hand, the first conductive gel layer of the present application is connected to a conductive elastic member on the side away from the supporting layer. The conductive elastic member can shrink when under pressure and can recover when not under pressure. When the patient's breathing causes local fluctuations, or for elderly patients, thin patients and patients with dry skin, the lead electrode sheet can fully adapt to the skin contact part, ensuring that the second conductive gel layer on the conductive elastic member can fully contact the skin contact part, improving the stability of the conductive signal, and avoiding large interference waves and artifacts in the electrocardiograph, which makes the electrocardiograph record inaccurate.

[0021] In addition, an adhesive layer is provided at the outer edge of the first conductive gel layer of the present application, and the lead electrode sheet can be fixed to the patient's skin with the help of the adhesive layer. A lead interface is provided in the circumferential direction of the conductive ball head, and the lead interface is connected to the external lead harness. This applies vertical pressure to the top of the center position of the lead electrode sheet, which can further increase the pressure of the lead electrode sheet on the skin contact part, making it more firmly and tightly bonded to the skin and not easy to slip off, thereby avoiding the problem of the lead electrode sheet being easy to slip due to the eccentric connection of the lead electrode sheet, which generates a large eccentric force.

[0022] In order to solve the technical problem, the further technical solution adopted by the utility model is:

[0023] Optionally, in the above-mentioned lead electrode sheet for an emergency electrocardiograph, the first conductive gel layer and the adhesive layer are both provided with a first release layer on a side away from the supporting layer, and the second conductive gel layer is provided with a second release layer on a side away from the conductive elastic member;

[0024] The design of the above technical solution, through the structural design of the first release layer and the second release layer, can well protect the surface hygiene of the first conductive gel layer, the adhesive layer and the second conductive gel layer, and ensure good bonding performance.

[0025] Further optionally, the above-mentioned lead electrode sheet for emergency electrocardiograph, wherein the lead electrode sheet further comprises a protective cover made of rubber material, and the protective cover is used to partially cover the lead electrode sheet;

In addition, it can also prevent the first release layer and the second release layer from falling off abnormally under the action of external force.

[0027] Further optionally, in the above-mentioned lead electrode sheet for an emergency electrocardiograph, the protective cover is provided with a curling edge and an abutting portion, the curling edge abuts against the supporting layer, and the abutting portion abuts against the second release layer;

[0028] In the design of the above technical solution, the rubber protective cover is designed with a curled edge and abutting portion, which can shrink and squeeze the lead electrode sheet and is not easy to fall off the lead electrode sheet.

[0029] Optionally, in the above-mentioned lead electrode sheet for an emergency electrocardiograph, a trapezoidal receiving groove is provided at a central position of a side of the first conductive gel layer away from the supporting layer, and the trapezoidal receiving groove accommodates the displacement movement of the conductive elastic member and the second conductive gel layer;

[0030] The design of the above technical solution, by opening a trapezoidal receiving groove at the center of the first conductive gel layer, ensures that the conductive elastic member is not interfered by the structure during the expansion and contraction process, thereby ensuring that it can successfully complete the functions of contraction under pressure and self-recovery without pressure.

[0031] Further optionally, in the above-mentioned lead electrode sheet for an emergency electrocardiograph, the conductive elastic member is a metal bellows, a wave spring or a conductive sponge;

[0032] The design of the above technical solutions uses metal bellows, wave springs or conductive sponges, all of which have the physical properties of shrinking under pressure and self-recovering when not under pressure, and are implementation options for conventional technical solutions.

[0033] Optionally, in the above-mentioned lead electrode sheet for an emergency electrocardiograph, the support layer is made of polypropylene material or polyester resin material;

[0034] In the design of the above technical solution, since the support layer plays a functional role in structural protection and structural stability of the lead electrode sheet, its compression resistance, corrosion resistance and deformation resistance should be good, so polypropylene or polyester resin material with better performance is used.

[0035] Optionally, in the above-mentioned lead electrode sheet for an emergency electrocardiograph, the through hole and the T-shaped limiting hole are located on the same axis, and the through hole is connected to the T-shaped limiting hole;

[0036] The design of the above technical solution, through the design of the penetration hole and the T-shaped limiting hole, enables the conductive ball head to be smoothly buried in the first conductive gel layer and pass through to be exposed on the supporting layer, which is beneficial to the structural stability of the conductive ball head.

[0037] Optionally, in the above-mentioned lead electrode sheet for an emergency electrocardiograph, the inner surface of the lead interface has a thread or a rough portion;

[0038] The design of the above technical solution, through the design of the thread or rough part on the inner surface of the lead interface, enables the external lead harness to be plugged into the lead interface and is not easy to fall off.

[0040] In the design of the above technical solution, one end of the conductive ball head is designed as a metal ball head, so that the lead electrode sheet is easy to manually take out and place, and the other end of the conductive ball head is designed as a metal T-shaped columnar body, so that it can be buried inside the first conductive gel layer and is not easy to fall off from the first conductive gel layer.

[0041] Compared with the prior art, this application has the following technical effects:

[0042] On the one hand, the present application adopts the design of the first conductive gel layer and the second conductive gel layer. Since the conductive gel layer is not easy to volatilize, has good conductivity and adhesion, is soft, has good hydrophilicity, does not irritate the skin, has moderate viscosity, and has long-lasting viscosity, the lead electrode sheet can be better attached to the patient's skin without affecting the conductivity of the skin, thereby enabling the electrophysiology of the heart to be more accurately fed back to the electrocardiograph;

[0043] On the other hand, the first conductive gel layer of the present application is connected to a conductive elastic member on the side away from the supporting layer. The conductive elastic member can shrink when under pressure and can recover when not under pressure. When the patient's breathing causes local fluctuations, or for elderly patients, thin patients and patients with dry skin, the lead electrode sheet can fully adapt to the skin contact part, ensuring that the second conductive gel layer on the conductive elastic member can fully contact the skin contact part, improving the stability of the conductive signal, and avoiding large interference waves and artifacts in the electrocardiograph, which makes the electrocardiograph record inaccurate.

[0044] In addition, an adhesive layer is provided at the outer edge of the first conductive gel layer of the present application, and the lead electrode sheet can be fixed to the patient's skin with the help of the adhesive layer.
