Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrocardiograph technology, specifically to an adsorption device for preventing electrocardiogram lead wires from falling off. Background Technology
[0002] An electrocardiogram (ECG) is a technique that uses an ECG machine to record the changes in electrical activity of the heart during each cardiac cycle from the body surface. When medical staff perform an ECG on a patient, they need to use lead wires. One end of the lead wire is connected to the examination machine, and the other end is attached to the patient's body through a lead bulb. However, many patients are thin or elderly people with loose skin, which makes it difficult for the lead bulb to adhere effectively to the patient's body. Therefore, an anti-drop-off attachment device is needed.
[0003] According to the patent application CN218528749U, "This utility model discloses an adsorption device for electrocardiogram (ECG) leads, comprising: a connecting sleeve with multiple sliding grooves and a metal suction sleeve fixedly connected externally; a pushing component for smoothing loose skin and disposed on the connecting sleeve; and an adsorption component for adsorbing the entire device onto the patient and disposed within the connecting sleeve. This adsorption device for ECG leads effectively solves the problem that when patients are thin or elderly with loose skin, the lead bulb cannot be adsorbed, leading to a significant waste of manpower."
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] In use, this invention first uses a push rod to contact the skin, spreading it out, and then attaches to the skin via a metal suction sleeve. When the push rod unfolds, it stretches a tension spring, causing the push rod to slide a sliding block within a sliding groove via a connecting rod. However, once the sliding block reaches a certain position, it cannot be fixed, resulting in the push rod also becoming unstable. Furthermore, the tension spring pulls the push rod inward, causing it to detach from the skin. Therefore, an improved adsorption device for ECG leads to prevent detachment is needed to address these issues. Utility Model Content
[0006] The purpose of this invention is to provide an adsorption device for preventing the electrocardiogram lead wire from falling off, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an adsorption device for preventing the electrocardiogram lead wire from falling off, comprising a hollow cylinder, wherein an unfolding mechanism is provided on the outside of the hollow cylinder, and an adsorption mechanism is provided on the hollow cylinder.
[0008] The unfolding mechanism includes a positioning component and an unfolding component. The positioning component is disposed outside the hollow cylinder, and the unfolding component is disposed outside the hollow cylinder.
[0009] Preferably, the positioning component includes an external threaded ring, which is fixedly connected to the outside of the hollow cylinder. A nut is threadedly connected to the outside of the external threaded ring, and a sliding ring is slidably connected to the outside of the external threaded ring. A connecting rod is fixedly connected to the outside of the sliding ring for fixing the angle of the support rod.
[0010] Preferably, the external threaded ring has a groove inside, and the sliding ring has a protrusion at the corresponding position of the groove, and the protrusion slides inside the groove. The nut contacts the sliding ring to fix the position of the sliding ring.
[0011] Preferably, the unfolding assembly includes a positioning ring, which is fixedly connected to the outside of the hollow cylinder. A first connecting seat is fixedly connected to the outside of the positioning ring. A support rod is rotatably connected inside the first connecting seat. An anti-slip pad is fixedly connected to the end of the support rod away from the first connecting seat. A spring is fixedly connected between the support rod and the hollow cylinder. A slider is slidably connected inside the support rod. A second connecting seat is fixedly connected to the end of the slider away from the support rod. The second connecting seat is rotatably connected to the outside of the connecting rod for unfolding the skin.
[0012] Preferably, the support rod has a groove at the corresponding position of the slider, and the slider slides inside the groove to limit the second connecting seat.
[0013] Preferably, the adsorption mechanism includes a limiting ring rotatably connected to the inside of the hollow cylinder. A handle is fixedly connected to the top of the limiting ring, and a screw is fixedly connected to the bottom of the limiting ring. A threaded cylinder is threadedly connected to the outside of the screw, and a gasket is fixedly connected to the bottom of the threaded cylinder. The gasket is slidably connected to the inside of the hollow cylinder, and a metal suction cup is fixedly connected to the bottom of the hollow cylinder for extracting air from the inside of the hollow cylinder.
[0014] Preferably, the hollow cylinder has a groove at the corresponding position of the gasket, and the gasket slides inside the groove to limit the position of the gasket.
[0015] Compared with the prior art, this utility model provides an adsorption device for preventing the dislodgement of electrocardiogram lead wires, which has the following beneficial effects:
[0016] 1. This anti-dislodgement ECG lead uses an adsorption device. During use, pressing the device causes the anti-slip pad to contact the skin. The support rod then spreads out through the anti-slip pad, allowing the support rod to rotate and unfold inside the first connecting seat. Simultaneously, the spring is stretched, and the slider slides inside the groove of the support rod. The slider drives the second connecting seat, which in turn drives the connecting rod. The connecting rod drives the sliding ring, which slides outside the external threaded ring. Once the metal suction cup is fully in contact with the skin, the nut is turned. The nut moves outside the external threaded ring, contacting the sliding ring and fixing its position. This fixes the position of the support rod, effectively preventing it from tilting itself and lifting the device, thus improving stability and preventing errors during inspection.
[0017] 2. The anti-detachment ECG lead wire adsorption device, during use, the handle drives the limiting ring, the limiting ring drives the screw, the screw drives the threaded cylinder, the threaded cylinder electric washer slides inside the hollow cylinder, so that the metal suction cup is adsorbed on the skin, thus adsorbing the device on the human skin, so as to facilitate device detection and use.
