Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, specifically to an electrocardiogram (ECG) suction bulb base auxiliary fixation device. Background Technology

[0002] Electrocardiography (ECG) is a primary means of clinical diagnosis of heart disease. It involves the ECG machine's electrodes contacting the skin to collect electrical activity signals from the heart, providing accurate diagnostic data for medical professionals. It is widely used in routine examinations, disease screening, and disease monitoring in medical institutions at all levels. Currently, the ECG electrodes used in clinical practice are primarily fixed by the suction of the electrode itself against the skin to ensure stable signal acquisition. While this traditional method meets basic clinical needs in the general population, it presents challenges for certain groups, particularly the elderly and frail. Elderly individuals with declining bodily functions have very little subcutaneous fat, loose and inelastic skin, making it difficult to create an effective seal. This prevents the suction of the ECG electrode from being fully utilized, leading to a high risk of electrode detachment. Even with repeated adjustments to the suction bulb position and pressure reinforcement by medical staff, it is difficult to achieve stable fixation of the suction bulb. This not only affects the continuity and accuracy of ECG signal acquisition, leading to errors in examination results and delaying disease diagnosis, but may also increase physical discomfort and psychological burden on the elderly due to repeated operations, thus reducing the examination experience.

[0003] In existing technologies, some ECG fixation devices primarily address issues such as lead wire entanglement and the inability to secure specific lead electrodes. For example, they utilize electrode bands and fixation rings to organize and secure the leads. However, they do not address the core challenge of poor suction bulb adhesion and fixation in elderly, thin individuals due to inelastic skin and minimal subcutaneous fat. Other auxiliary fixation devices attempt to solve the problem of suction bulb detachment, but their complex structures, cumbersome operation, and poor adaptability prevent them from flexibly adapting to elderly individuals of different body types, thus failing to meet the actual needs of clinical use. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, the present invention provides an auxiliary fixation device for an electrocardiogram suction bulb base.

[0005] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: An auxiliary fixation device for an electrocardiogram (ECG) suction bulb base includes a clamping part and an adsorption part.

The cross structure includes a cross rod and a cross middle rod, and a central shaft is provided between the cross rod and the cross middle rod. The fork rod is fixedly connected to the central shaft, the cross middle rod is rotatably connected to the central shaft, and a central spring is fixedly connected between the fork middle rod and the central shaft. The cross rod is fixedly connected to the first clamping ring at one end near the clamping end, and the cross middle rod is fixedly connected to the second clamping ring at one end near the clamping end; the clamping assembly also includes a control handle as a control end, and the cross rod and the cross middle rod are fixedly connected to the control end side with the control handle.

[0007] Preferably, the expansion assembly includes an extension arm, the first end of which is fixedly connected to the clamping ring, the extension arm extends away from the center of the clamping ring and extends to one side of the clamping ring axis, and the second end of the extension arm is fixedly connected to an attachment shell, the attachment shell being provided with an adsorption assembly.

[0008] Preferably, the linkage assembly includes a linkage handle, a control seat is fixedly connected to the side of the control handle away from the other control handle, a control shaft is fixedly connected to the middle of the control seat, a linkage seat is fixedly connected to the linkage handle, the linkage seat is rotatably connected to the control shaft, and a linkage spring is fixedly connected between the linkage seat and the control seat. The control handle has an arc groove on the side near the linkage handle. An arc handle is fixedly connected to the linkage handle on the side near the arc groove. The arc handle slides within the arc groove. A control tube is fixedly connected inside the control handle and communicates with the arc groove. A control branch tube is fixedly connected to the end of the control tube away from the linkage handle. The control branch tube is fixedly connected to the cross rod and the cross middle rod respectively. A diverter tube is fixedly connected inside the clamping ring and is fixedly connected to the control branch tube. A branch tube is fixedly connected to the diverter tube at the corresponding position of the extension arm. The branch tube is fixedly connected inside the extension arm, and the end of the branch tube away from the clamping ring communicates with the inside of the attachment shell.

[0009] Preferably, the adsorption assembly includes a sliding plate slidably connected to an attachment shell, a piston fixedly connected to the lower side of the attachment shell, a fixed plate fixedly connected to the lower side of the attachment shell, a sliding cylinder fixedly connected to the upper side of the fixed plate, the piston slidably connected to the sliding cylinder, a suction cup fixedly connected to the lower side of the fixed plate, the suction cup communicating with the sliding cylinder, and the branch tube located on the side of the sliding plate away from the fixed plate.

[0010] Preferably, the distance between the end face of the attachment shell on the suction cup side and the extension arm is smaller than the distance between the end face of the suction cup and the extension arm.

[0011] Preferably, the clamping ring is provided with two extension arms, and the positions of the attachment shell are arranged in a circular four-point array relationship.

[0012] Preferably, the attachment shell contains four suction cups, which are made of silicone and are smaller than the size of the suction base.

[0013] Preferably, the existing suction ball has a suction seat on its lower side, and a connecting neck is provided between the suction ball and the suction seat, with a connecting frame connected to the connecting neck.

[0014] The beneficial effects of this invention are: An auxiliary fixation device for an electrocardiogram (ECG) suction bulb base is disclosed. During use, two fingers are placed on the two linkage handles and squeezed. Initially, the linkage handles move closer to the control handle, causing the arc handle to compress gas within the arc groove. This gas is then pushed between the attachment shell and the sliding plate through the control tube, control branch tube, shunt tube, and shunt branch tube. The sliding plate then drives the piston downwards within the slide cylinder. As compression continues, the cross structure shifts, causing the two clamping rings to open and clamp onto the upper connecting neck of the clamping bracket. At this point, the extension arms carried by the clamping rings move the attachment shell around the suction base, allowing it to contact the skin via silicone suction cups while maintaining contact between the suction base and the skin. Releasing the fingers causes the control handle to reset under the action of the central spring, and the clamping rings clamp onto the connecting neck. Finally, as the fingers are released, the linkage handles are released by the linkage spring. The mechanism resets the suction cups by drawing air from the arc groove, reducing the amount of gas between the sliding plates and causing the piston to move upward within the cylinder. This reduces the air pressure on the suction cups, generating suction. During operation, a single pressing action triggers two actions: opening the clamping ring and applying negative pressure. The negative pressure control is located close to the pressing control, allowing for control without changing the operation. Logically, squeezing the control handle synchronizes the opening of the clamping ring and the release of the suction cups, while releasing the control handle synchronizes the clamping ring clamping and the negative pressure suction of the suction cups. The use of silicone material, a structure smaller than the suction cup itself, and multiple suction cups distributed around the perimeter solves the problem of suction cups being unable to adhere to and fix the skin of elderly, thin individuals with inelastic skin and little subcutaneous fat.
