Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a chest electrode. Background Technology

[0002] In today's era of rapid advancements in medical technology, accurate diagnosis and effective monitoring are crucial for ensuring patients receive timely and accurate treatment. Among numerous medical devices, electrocardiogram (ECG) electrodes, as key components for collecting vital physiological parameters such as electrocardiogram signals, directly impact the accuracy and reliability of medical diagnoses.

[0003] With the increasing demands for medical quality and the continuous innovation of medical technology, existing chest electrodes have the following shortcomings in practical use: primarily two issues related to detachment. One is the easy separation of the bulb from the base, and the other is the tendency for the chest electrode to detach from the patient's skin. This is due to insufficient negative pressure. The existing chest electrodes use elastic rubber bulbs, which may not fully rebound during use, and after prolonged use, the rubber bulbs gradually fatigue and age, leading to reduced elasticity. This results in the bulbs not fully expanding and contracting when adhering to the skin, reducing their ability to generate negative pressure and consequently decreasing the adhesion. Therefore, the chest electrode proposed in this application is presented. Utility Model Content

[0026] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] like Figures 1 to 2 As shown, a chest electrode 1 includes a base 10 and a suction ball 20. The suction ball 20 includes an upper hemisphere 21, a lower hemisphere 22, a reinforcing ring 30, and several reinforcing ribs 40. The lower hemisphere 22 has a sleeve 221, which is fitted onto the base 10 and communicates with the base 10. The upper hemisphere 21 is disposed on the lower hemisphere 22 so that the upper hemisphere 21 and the lower hemisphere 22 together form an air chamber, and the air chamber communicates with the sleeve 221. The reinforcing ring 30 is disposed at the position where the upper hemisphere 21 and the lower hemisphere 22 are connected. Each reinforcing rib 40 is disposed on the inner wall of the upper hemisphere 21, and one end of each reinforcing rib 40 is connected to each other, and the other end of each reinforcing rib 40 extends to the inner wall of the lower hemisphere 22.

[0031] It should be noted that both the upper hemisphere 21 and the lower hemisphere 22 are bowl-shaped structures, and the upper hemisphere 21 and the lower hemisphere 22 are the same size, so that when the upper hemisphere 21 and the lower hemisphere 22 are interlocked, they can form a sphere, and together they form a spherical air chamber on one side. Furthermore, the sleeve 221 tends to be a circular tube structure, with its two ends connected. One end of the sleeve 221 is set on the lower hemisphere 22 and communicates with the interior of the air chamber. The sleeve 221 is fitted onto the base 10 so that the interior of the air chamber can communicate with the base 10. Furthermore, a number of reinforcing ribs 40 are provided on the inner sidewall of the upper hemisphere 21, and one end of each reinforcing rib 40 is connected to each other. Furthermore, the other ends of each reinforcing rib 40 are distributed at intervals on the inner wall of the upper hemisphere 21 and extend to the inner wall of the lower hemisphere 22. When the suction ball 20 is squeezed by external force, both the upper hemisphere 21 and the lower hemisphere 22 are concave inward, which in turn causes each reinforcing rib 40 to concave inward as well. This allows the gas inside the air chamber to flow from the sleeve opening 221 to the base 10 and then out of the base 10. Since the suction ball 20 is made of elastic rubber ball, when the suction ball 20 is freed from the external force, each reinforcing rib 40 together supports the upper hemisphere 21 and the lower hemisphere 22 to quickly return to their original shape. At the same time, this allows air to flow from the base 10 through the sleeve opening 221 into the air chamber more quickly. Furthermore, each reinforcing rib 40 is spaced apart on the inner sidewall of the upper hemisphere 21 and the lower hemisphere 22, thereby increasing the wall thickness of the suction ball 20, improving the elasticity and adsorption capacity of the suction ball 20, reducing the time it takes for the suction ball 20 to gradually fatigue and age after long-term use, and thus improving the service life of the chest electrode 1 of this application.

[0032] like Figures 1 to 4 As shown, in one embodiment, the reinforcing ring 30 includes a ring band 31 and a plurality of reinforcing bars 32. The ring band 31 is disposed at the position where the upper hemisphere 21 and the lower hemisphere 22 are connected. Each reinforcing bar 32 is disposed at intervals on both sides of the ring band 31. A portion of each reinforcing bar 32 extends to the upper hemisphere 21, and another portion of each reinforcing bar 32 extends to the lower hemisphere 22.

[0033] It should be noted that since the openings of the upper hemisphere 21 and the lower hemisphere 22 are at their maximum diameters, and the elasticity at the maximum diameter of a sphere is less than that at its minimum diameter, the upper hemisphere 21 and the lower hemisphere 22 are joined together at their maximum diameters to form a sphere, thereby creating an air chamber inside. Furthermore, a ring band 31 is positioned at the connection point between the upper hemisphere 21 and the lower hemisphere 22, with one half of the ring band 31 located on the upper hemisphere 21 and the other half on the lower hemisphere 22, to increase the elasticity at the connection point. Simultaneously, each force-adding strip 32 is spaced apart on both sides of the ring band 31. Since one half of the ring band 31 is located on the upper hemisphere 21, one half of each force-adding strip 32 extends from one side of the ring band 31 to the upper hemisphere 21; similarly, the other half of the ring band 31 is located on the lower hemisphere 22, allowing the other half of each force-adding strip 32 to extend from the other side of the ring band 31 to the lower hemisphere 22. This increases the elasticity at the connection between the upper hemisphere 21 and the lower hemisphere 22.

[0034] like Figure 5 As shown, in one embodiment, the base 10 includes a suction cup 13, an electrode plate 11, and a retaining tube 12. One end of the retaining tube 12 is disposed on the electrode plate 11, and the other end of the retaining tube 12 is inserted into the sleeve 221 and the retaining tube 12 is connected to the sleeve 221. The suction cup 13 is disposed on the side of the electrode plate 11 away from the retaining tube 12 and the suction cup 13 is connected to the electrode plate 11.

[0035] It should be noted that the electrode 11 is disposed on the suction cup 13 and located between the suction cup 13 and the card tube 12. When the suction cup 13 is attached to the skin, the electrode 11 can quickly transmit the electrical signal received by the suction cup 13. Furthermore, the clamping tube 12 is provided with several retaining rings 121, which are spaced apart on the outer side wall of the clamping tube 12. The inner side wall of the sleeve 221 is provided with several inner grooves 2211, and each inner groove 2211 corresponds to each retaining ring 121. When the clamping tube 12 is inserted into the sleeve 221, the clamping tube 12 simultaneously drives each retaining ring 121 to be inserted into the sleeve 221 and engaged with each inner groove 2211, so that the clamping tube 12 can be firmly fixed on the sleeve 221. Furthermore, the width of the inner groove 2211 is slightly smaller than the width of the retaining ring 121, so that after each retaining ring 121 is engaged in the inner groove 2211, the inner groove 2211 can clamp each retaining ring 121, thereby sealing the clamping tube 12 in the sleeve 221.

[0036] It should be noted that the retaining ring 121 closest to the suction ball 20 has a beveled part, and the beveled part faces the suction ball 20, so that when the suction ball 20 is engaged with the retaining tube 12, the sleeve 221 on the suction ball 20 can be smoothly fitted onto the retaining tube 12 by being guided by the beveled part.

[0037] It should be noted that the electrode pad 11 is provided with an electrode socket, which is circular in shape, so that one end of the wire is inserted into the electrode socket so that the electrical signal received on the suction cup 13 can be transmitted to the receiving device through the wire. (For example, the wire is a lead wire structure, and the receiving device is the main unit of the electrocardiogram detection device).

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
