Description

Technical Field

[0001] The utility model relates to the technical field of electrocardiogram measurement, in particular to an electrocardiogram-specific electrode sheet and an electrocardiogram lead suction head. Background Art

[0002] An electrocardiogram (ECG) is a technique that uses an electrocardiograph (ECG) machine to record the changes in electrical activity during each cardiac cycle from the body's surface. Electrodes are placed on different parts of the body and connected to the positive and negative electrodes of the ECG machine's ammeter via lead wires. This circuit connection method for recording the ECG is called an ECG lead system. The widely adopted international lead system is called the conventional 12-lead system, which includes limb leads connected to the limbs and chest leads connected to the chest.

[0003] However, in the existing ECG lead process, when the lead tip and the electrode sheet are connected through the lead wire, the connection is generally achieved only by engaging the end of the lead wire with the tip and the end of the electrode sheet respectively. This connection is very unstable. When the patient's body shakes, the end of the lead wire may cause it to fall off from the tip or the electrode sheet, which can easily cause poor contact. In particular, the electrode sheet connected to the patient's limbs is prone to fall off when the lead wire and the electrode sheet are cross-connected due to the unevenness of the limbs. The electrode sheet may also fall off from the patient's limb due to insufficient contact with the skin, thereby affecting the measurement accuracy of the ECG. In this regard, the present design proposes a special ECG electrode sheet and an ECG lead tip. Utility Model Content

[0004] The purpose of the present invention is to provide an electrocardiogram (ECG) electrode sheet and an ECG lead suction head, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention proposes an electrocardiogram electrode sheet and an electrocardiogram lead suction head, comprising an electrode sheet body, a branch lead wire, a connecting suction head, and a fixing assembly installed at the upper ends of the electrode sheet body and the connecting suction head;

[0006] The fixing component includes a first silicone gel in the middle position of one side of the electrode sheet body, a second silicone gel is fixed at the four corners of one side of the electrode sheet body, a connecting wire is inserted and connected to the other side of the electrode sheet body, and the connecting wire passes through the inner wall of the electrode sheet body and is connected to the first silicone gel, one end of the connecting wire and one side of the connecting head are connected to the docking shaft, the outer walls of one end of the two docking shafts are equidistantly provided with storage holes, the inner wall of each of the storage holes is inserted with a buckle, and a spring is fixed on one side of the inner wall of each of the storage holes, and one end of each spring is fixedly connected to one end of each buckle.

[0007] In one example, rubber bands are fixed to the edges of both ends of one side of the electrode sheet body, and felt is fixed to one side of the two rubber bands.

[0008] In one example, the multiple ends of the branch lead wires are fixedly connected to connectors, a clamping hole is opened on one side of each connector, and the outer walls of one end of the two docking shafts are respectively connected with the inner walls of two of the clamping holes.

[0009] In one example, the inner wall of each of the clamping holes is provided with a plurality of limiting grooves at equal distances, and the outer wall of one end of each buckle is respectively interlaced and connected with the inner wall of each limiting groove.

[0010] In one example, a rubber airbag is installed at one end of the connecting nozzle, and an inner wall of one end of the rubber airbag is in communication with an inner wall of the connecting nozzle.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: when the tap lead wire connects the connecting tip and the electrode sheet lead, a docking shaft with a fixing component is provided on the connecting tip and the electrode sheet body, and the connector on the tap lead wire is clamped into the docking shaft, so that it squeezes the buckle and compresses the spring, and then the buckle is probed into the limiting groove on the connector by the spring, so that the connector, the connecting tip and the electrode sheet body can be firmly fixed, and when the electrode sheet is connected to the limb, the rubber strap and felt on the electrode sheet body are wrapped around the limb to fix the electrode sheet body and tightly adhere to the skin of the limb, thereby solving the problems of easy detachment of the existing lead tip and the motor sheet during connection due to shaking and poor contact of the electrode sheet when connected to the limb due to uneven skin contact surface, thereby improving the accuracy of electrocardiogram measurement.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5 The utility model provides a technical solution: an electrocardiogram electrode sheet and an electrocardiogram lead suction head, comprising an electrode sheet body 1, a branch lead wire 2, a connecting suction head 3, and a fixing component 4 installed on the upper ends of the electrode sheet body 1 and the connecting suction head 3;

[0020] The fixing component 4 includes a first silicone rubber 401 in the middle of one side of the electrode sheet body 1, and a second silicone rubber 402 is fixed at the four corners of one side of the electrode sheet body 1. A connecting wire 403 is inserted and connected to the other side of the electrode sheet body 1, and the connecting wire 403 passes through the inner wall of the electrode sheet body 1 and is connected to the first silicone rubber 401. One end of the connecting wire 403 and one side of the connecting tip 3 are connected to a docking shaft 404. The outer walls of one end of the two docking shafts 404 are equidistantly provided with receiving holes 405. The inner wall of each receiving hole 405 is inserted with a buckle 406, and one side of the inner wall of each receiving hole 405 is fixed with a spring 407. One end of each spring 407 is fixedly connected to one end of each buckle 406. When the electrode sheet body 1 is adsorbed on the skin of a patient other than a limb, the first silicone rubber 401 and the second silicone rubber 402 on one side of the electrode sheet body 1 can be directly used to contact and fit the skin. Then, the electrode sheet body 1 is adsorbed on the skin and connected to the connecting nozzle 3 adsorbed near the heart through the tapping lead 2 for current conduction. When the electrode sheet body 1 is attached to the patient's skin, the first silicone rubber 401 is connected to the docking shaft 404 and the tapping lead 2 through the connecting wire 403, so that the measured current can flow smoothly on the patient's body.

[0021] When in use, the connecting suction head 3 and the electrode sheet body 1 are respectively adsorbed on various parts of the patient's body, and then the connecting suction head 3 and the electrode sheet body 1 are connected through the tapping lead wire 2, and the tapping lead wire 2 is used to dock with the electrocardiograph to perform electrocardiogram measurement. In the connection process, the connectors 410 on each end of the tapping lead wire 2 are docked with the connecting suction head 3 and the electrode sheet body 1. When docking, the clamping hole 411 on one side of the connector 410 is clamped on the end of each docking shaft 404, and pressed hard to make the end of the docking shaft 404 clamped in the clamping hole 411, and the buckle 4 on the outer wall of the docking shaft 404 is clamped. 06 is squeezed and compressed, and the spring 407 shrinks in the receiving hole 405, so that the end of the docking shaft 404 can smoothly enter the clamping hole 411, and when each clamping buckle 406 is facing the limiting groove 412, the clamping buckle 406 is clamped into the limiting groove 412 under the elastic action of the spring 407, and the connector 410 is firmly docked with the connecting head 3 and the docking shaft 404 on the electrode body 1. After the measurement is completed, the connector 410 can be pulled off the docking shaft 404 with force, so that during the electrocardiogram measurement process, it is not easy to fall off and have poor contact due to loose connection, thereby improving the accuracy of electrocardiogram measurement;

[0022] Furthermore, rubber bands 408 are fixed to the edges of both ends of one side of the electrode sheet body 1, and felt 409 is fixed to one side of each of the two rubber bands 408. When the electrode sheet body 1 is connected and adsorbed on a limb, the rubber bands 408 at both ends of the electrode sheet body 1 are bound to each other, and the felt 409 on them are adsorbed to each other, so that the electrode sheet body 1 can be firmly adsorbed on the skin surface of the limb, which is not likely to cause poor contact or shaking and falling off.

[0023] Furthermore, multiple ends of the branch lead wire 2 are fixedly connected to the connector 410, and a card hole 411 is opened on one side of each connector 410, and the outer walls of one end of the two docking shafts 404 are respectively connected with the inner walls of two of the card holes 411, and the end of each buckle 406 is spherical. After being inserted into the limiting groove 412, it can be squeezed open by force to squeeze the spring 407 again and stored in the storage hole 405, and then the connector 410 can be pulled out from the docking shaft 404.

[0024] The inner wall of each latch hole 411 is provided with a plurality of limiting grooves 412 at equal distances, and the outer wall of one end of each latch 406 is respectively interlaced with the inner wall of each limiting groove 412;

[0025] Furthermore, a rubber airbag 5 is installed at one end of the connecting suction head 3, and the inner wall of one end of the rubber airbag 5 is connected to the inner wall of the connecting suction head 3. When the connecting suction head 3 is adsorbed near the patient's chest cavity, the air in the connecting suction head 3 is expelled by squeezing the rubber airbag 5, and then it is tightly attached to the skin surface. The pressure difference between the inside and the outside is separated, so that the connecting suction head 3 is tightly attached to the skin, making it difficult for the suction head to fall off during the electrocardiogram measurement, and the measurement is more stable.
