Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a fixing device for electrocardiogram electrodes. Background Art

[0002] Electrocardiographs are instruments used to record physiological electrical signals generated by heart activity and are commonly used in hospitals at all levels. When in use, electrodes are used to obtain bioelectrical phenomena and transmit them to the electrocardiograph through wires. Currently, the electrodes commonly used in clinical practice are button electrodes.

[0003] As attached Figure 1 As shown, the electrocardiogram button electrode of the prior art includes a fixing head 01, a fixing buckle 02 installed on the top of the fixing head 01 and an electrode wire 03, one end of the fixing head 01 connected to the electrode wire 03 is a connecting shell 04, and a fixing device used to match the electrocardiogram button electrode and fix the button electrode on the patient is a snap-on electrode patch, as shown in the attached Figure 2 As shown, the snap-on electrode patch includes a patch 1 and a hidden buckle 2 that passes through the patch 1. When used clinically, the fixing buckle 02 is first snapped onto the hidden buckle 2 to connect the fixing head 01 to the patch 1, and then the patch 1 is pasted to the position where the patient needs to fix the electrode.

[0004] Since the patch has a large contact area with the human body, the patch is not easy to fall off. However, the ECG button electrode and the patch are only connected by the buckle and the fixing buckle, and the connection strength is low. Under the action of external force, the fixing head and the patch are easily separated, causing the ECG button electrode to fall off, affecting ECG monitoring. Utility Model Content

[0005] The utility model aims to provide a fixing device for electrocardiogram electrodes, so as to solve the technical problem that the connection strength of the electrocardiogram button-type electrode patch is low in the prior art, which makes the electrodes easy to fall off.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0008] As a preferred solution of the utility model, the top of the blocking plate is arranged as a slope inclined downward, and the slopes on the two blocking plates are arranged opposite to each other.

[0009] As a preferred solution of the utility model, a pressing block is provided on the top of the blocking plate, and the pressing block is slidably connected to the limiting plate in the vertical direction through a slider on one side of the pressing block close to the limiting plate, and a lower pressure plate is fixedly connected to the bottom of the other side of the pressing block, and the lower pressure plate is arranged directly above the inclined surface, so that when the pressing block is subjected to a downward force, the lower pressure plate squeezes the blocking plate to move the blocking plate toward the side of the spring.

[0011] The utility model limits and fixes the fixed head of the electrocardiogram button electrode by providing a limit plate and a blocking plate, thereby improving the connection strength between the button electrode and the patch, making it difficult for the button electrode and the patch to be separated, thereby improving the connection tightness between the button electrode and the patient, being able to withstand greater pulling force, and making it difficult for the button electrode to fall off.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 3 As shown, the present invention provides a fixing device for electrocardiogram electrodes, which mainly limits and fixes the fixing head 01 of the electrocardiogram button electrode through a limiting plate 3 and a blocking plate 5.

[0021] The fixing device of the electrocardiogram electrode includes a patch 1 and a concealed buckle 2. A limiting plate 3 is fixedly connected to one side of the patch 1 connected to the fixed head 01. A limiting groove 4 matching the outer surface of the fixed head 01 is opened on the top of the limiting plate 3. Both sides of the inner wall of the limiting groove 4 corresponding to the connecting shell 04 are provided with blocking plates 5. A spring 6 is fixedly connected between the blocking plate 5 and the inner wall of the limiting groove 4, and the blocking plate 5 is slidably connected to the limiting plate 3 in the horizontal direction through a sliding rod 7, so that when the fixing buckle 02 on the fixed head 01 is buckled with the concealed buckle 2, the fixed head 01 is clamped in the limiting groove 4, and the limiting plate 3 limits the top of the fixed head 01, thereby preventing the fixed head 01 from moving up.

[0022] The ECG button electrode used in the prior art is connected to the patch 1 only by the buckle 2 and the fixing buckle 02, and the connection strength is low. Under the action of external force, the fixing head 01 is easily separated from the patch 1, thereby causing the ECG button electrode to fall off. Therefore, it is necessary to develop a fixing device for ECG electrodes that is not easy to fall off.

[0023] In this embodiment, a limiting plate 3 and a blocking plate 5 are provided to limit and fix the fixed head 01 of the electrocardiogram button electrode, thereby improving the connection strength between the button electrode and the patch 1, making it difficult for the button electrode and the patch 1 to be separated, thereby improving the connection tightness between the button electrode and the patient, being able to withstand greater pulling force, and making it difficult for the button electrode to fall off.

[0024] In actual use, 1. snap the fixing head 01 into the limiting groove 4, and make the fixing buckle 02 on the fixing head 01 buckle with the hidden buckle 2;

[0025] 2. During the process of the fixing head 01 and the limiting groove 4 being clamped together, the connecting shell 04 squeezes the blocking plate 5, so that the spring 6 is compressed, and the blocking plate 5 moves toward the limiting plate 3 until the connecting shell 04 moves to the bottom of the limiting groove 4. At this time, due to the rebound force of the spring 6, the blocking plate 5 moves away from the limiting plate 3, so that the blocking plate 5 moves to the top of the connecting shell 04, limiting the top of the connecting shell 04;

[0026] 3. Fix the device on the patient through patch 1.

[0027] Since the blocking plate 5 limits the top of the fixing head 01, the fixing head 01 is not easily separated from the patch 1 when subjected to an upward pulling force.

[0028] As a preferred embodiment of this embodiment, the top of the blocking plate 5 is set as a slope 8 tilted downward, and the two upper slopes 8 of the blocking plates 5 are arranged opposite to each other. Since the connecting shell 04 is a downward force, in order to better move the blocking plate 5 to both sides of the connecting shell 04, the top of the blocking plate 5 is set as a slope 8 tilted downward.

[0029] Furthermore, in order to facilitate the separation of the fixed head 01 from the patch 1, a pressing block 9 is provided on the top of the blocking plate 5. The pressing block 9 is slidably connected to the limiting plate 3 in the vertical direction through a slider 10 on one side of the pressing block 9 close to the limiting plate 3. A lower pressing plate 11 is fixedly connected to the bottom of the other side of the pressing block 9, and the lower pressing plate 11 is arranged just above the inclined surface 8, so that when the pressing block 9 is subjected to a downward force, the lower pressing plate 11 squeezes the blocking plate 5 and moves the blocking plate 5 toward the side of the spring 6. When the fixed head 01 needs to be separated from the patch 1, the pressing block 9 is pressed downward, so that the slider 10 slides down in the limiting plate 3, and the lower pressing plate 11 presses the inclined surface 8 downward, so that the blocking plate 5 moves toward the two sides of the connecting shell 04. At this time, a pulling force is applied upward to the fixed head 01, so that the fixed head 01 is separated from the patch 1. Since it is necessary to apply a downward pressing force and an upward pulling force at the same time in this embodiment, it is not easy to pull out the fixed head 01 in actual use.

[0030] In order to allow the fixing head 01 to be smoothly inserted and removed, when the spring 6 is in the initial state, the distance between the two blocking plates 5 is smaller than the width of the connecting shell 04, and when the spring 6 is compressed, the distance between the two blocking plates 5 is larger than the width of the connecting shell 04;

[0031] The distance between the two lower pressing plates 11 is greater than the width of the connecting shell 04 .

[0032] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
