Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to an auxiliary device for electrocardiography. Background Technology

[0002] An electrocardiogram (ECG) is a medical device that examines patients by capturing changes in various bioelectrical phenomena within the human body. Since human bioelectricity is very weak, the contact between the electrodes and the skin directly affects the accuracy of the ECG readings. Currently, a common method is to apply conductive solution (clinically, alcohol diluted with tap water is used instead) to the contact area between the electrodes and the skin using a sterile cotton ball. However, this method has the following drawbacks: Because there are many electrodes, applying the conductive solution is tedious and time-consuming, which affects the speed of electrocardiogram examination, increases the workload of medical staff, and consumes a large amount of disinfectant cotton balls and medical alcohol.

[0003] Because the conductive liquid (alcohol mixed with tap water) is volatile, a long application interval can cause differences in the contact conditions of each electrode point, thus affecting the accuracy of the electrocardiogram examination. In addition, the evaporation of alcohol in cold weather can also cause some discomfort to patients. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing an auxiliary device for electrocardiography using a self-flowing conductive fluid. This invention has a simple structure, is easy to use, significantly improves examination efficiency and accuracy, reduces the workload of medical staff, and enhances patient comfort.

[0005] This invention is achieved through the following technical solution: providing an auxiliary device for electrocardiography using a self-flowing conductive liquid, comprising a clip electrode, a suction cup electrode, a multi-compartment container, a support rod, locking wheels, a container cap, conductive liquid, a heating device, and a capillary tube. The multi-compartment container has multiple compartments; one end of the capillary tube is inserted into a compartment of the multi-compartment container after passing through the container cap, and the other end is fixed to the clip electrode or suction cup electrode. The multi-compartment container is fitted onto the support rod and can slide up and down; after the relative height is adjusted, it is fixed with the locking wheels. The heating device is fitted onto the multi-compartment container and is used to heat the conductive liquid in cold weather. Under the combined action of siphon and capillary effect, the conductive liquid remains in a static flow state at the electrode ports, allowing the conductive liquid to be evenly applied to the skin when the electrodes move on the skin. This invention has a simple structure, is easy to use, significantly improves examination efficiency and accuracy, reduces the workload of medical staff, enhances patient comfort, and greatly saves on medical consumables.

[0006] In clinical practice, during electrocardiogram (ECG) examinations, the conductive fluid remains stationary at the electrode ports due to the combined effects of siphon and capillary action. As the electrode moves across the skin, the conductive fluid is evenly spread. This invention features a simple structure, ease of use, significantly improved examination efficiency and accuracy, reduced workload for medical staff, enhanced patient comfort, and substantial savings in medical consumables.

[0007] In the above-mentioned auxiliary device for electrocardiography using self-flowing conductive fluid, the multi-compartment container is a cylinder with a through hole in the middle, the size of which is adapted to the support rod, and the multi-compartment container is divided into multiple compartments.

[0008] In the above-mentioned auxiliary device for electrocardiography using a self-flowing conductive liquid, the container cap is provided with multiple through holes, the diameter of which is slightly larger than the outer diameter of the capillary tube to facilitate the passage of the capillary tube.

[0009] In a preferred embodiment of the above-mentioned auxiliary device for electrocardiography using a self-flowing conductive liquid, both the clamp electrode and the suction cup electrode have a small hole on their metal blocks, the inner diameter of which matches the outer diameter of the capillary tube. One end of the capillary tube is inserted into the small hole and fixed with glue.

[0010] In the aforementioned auxiliary device for electrocardiography using a self-flowing conductive liquid, the capillary is preferably composed of multiple plastic tubes of different diameters, which enhances the strength of the capillary and prevents it from bending and becoming blocked.

[0011] The beneficial effects of this invention are as follows: This invention has a simple structure, is easy to use, greatly improves examination efficiency and accuracy, reduces the workload of medical staff, enhances patient comfort, and saves a lot of medical consumables.

[0013] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0014] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1, as Figure 2 As shown, an auxiliary device for electrocardiography using a self-flowing conductive fluid includes a clip electrode (1), a suction cup electrode (2), a multi-compartment container (3), a support rod (4), a locking wheel (5), a container cap (6), conductive fluid (7), a heating device (8), and a capillary tube (9). The multi-compartment container (3) has multiple compartments F, each compartment F being filled with conductive fluid (7). Clinically, alcohol mixed with tap water is usually used instead of conductive fluid, which has both conductive and disinfecting functions. One compartment F corresponds to one clip electrode (1) or one suction cup electrode (2) to prevent series interference during bioelectrical data collection, which would affect the accuracy of the examination. The capillary tube... One end of the tube (9) passes through the through hole E of the container cap (6) and is inserted into the compartment F of the multi-compartment container (3). It is tied together with the conductive wire in the middle and the other end is fixed to the clip electrode (1) or the suction cup electrode (2). Under the combined action of siphon and capillary effect, the conductive liquid always remains in a static flow state at the clip electrode (1) or the suction cup electrode (2). When the electrode moves on the patient's skin, the conductive liquid can be evenly applied to the patient's skin. The multi-compartment container (3) is fitted on the support rod (4) and can slide up and down. After adjusting the height difference, it is fixed with the locking wheel (5). The heating device (8) is fitted on the multi-compartment container (3).

[0016] When performing an electrocardiogram on a patient, there is no need to treat the patient's skin with a sterile cotton ball soaked in conductive liquid. The conductive liquid used in clinical practice is actually alcohol mixed with tap water, which has the dual functions of conductivity and disinfection. The clip electrode (1) and suction cup electrode (2) are moved back and forth on the patient's skin, and the conductive liquid can be evenly applied to the patient's skin. In cold weather, the heating device (8) is turned on to heat the alcohol to a suitable temperature, and a fast and accurate examination process is completed.

[0017] The above-mentioned conductive liquid self-flowing electrocardiogram auxiliary device has a multi-compartment container (3) which is a cylinder with a through hole in the middle, the size of which is adapted to the support rod (4), and the multi-compartment container (3) is divided into multiple compartments F.

[0018] The above-mentioned conductive liquid self-flowing electrocardiogram auxiliary device has multiple through holes E on the container cap (6), the diameter of which is slightly larger than the outer diameter of the capillary tube, so that the capillary tube can pass through.

[0019] In the aforementioned auxiliary device for electrocardiography using a self-flowing conductive liquid, both the clamp electrode (1) and the suction cup electrode (2) have a small hole on their metal blocks, the inner diameter of which matches the outer diameter of the capillary tube. One end of the capillary tube is inserted into the small hole and fixed with glue.

[0020] The above-mentioned auxiliary device for electrocardiogram with self-flowing conductive liquid has a capillary (9) made of multiple plastic tubes of different diameters, which enhances the strength of the capillary and prevents the capillary from bending and clogging.

[0021] This invention has a simple structure, is easy to use, greatly improves examination efficiency and accuracy, reduces the workload of medical staff, enhances patient comfort, and saves a lot of medical consumables.

[0022] Of course, the above description is not limited to the examples above. Technical features not described in this invention can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solutions of this invention and are not intended to limit this invention.
