Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an electrode plug connection structure with an anti-drop function and a defibrillator. Background Art

[0002] Cardiac arrest can cause a momentary interruption of blood circulation, making it impossible for the brain and other important organs of the body to obtain sufficient oxygen and nutrition. After 20 seconds of cerebral circulation cessation, the patient will lose consciousness, and after 5 minutes of complete cerebral hypoxia, irreversible brain damage will occur. Therefore, it is crucial for everyone to improve their awareness and ability to respond to this emergency. A defibrillator is a medical device specifically used to rescue patients with cardiac arrest. It uses a strong pulse current through the heart to eliminate arrhythmias and restore sinus rhythm. It is a medical device that is essential for all departments of the hospital.

[0003] The defibrillator includes a main unit and a defibrillation electrode plate, the electrode plate is connected to an electrode plug via a wire, an electrode connector is fixedly provided on the main unit, and the electrode plug is plugged into the electrode connector. In the prior art, the connection reliability between the electrode plug and the electrode connector is insufficient. Due to the complexity of the emergency scene, medical staff may pull the wire during operation, which may easily cause poor contact or fall off of the electrode plug, delaying emergency treatment. Summary of the invention

[0004] The first purpose of the present invention is to provide an electrode plug connection structure with an anti-dropping function to address the problem that the connection reliability between the electrode plug and the electrode connection socket of the defibrillator in the prior art is insufficient, and when the wire is accidentally pulled, the electrode plug is likely to have poor contact or fall off, thereby delaying emergency treatment. The second purpose of the present invention is to provide a defibrillator.

[0005] In order to achieve the above first purpose, the technical solution adopted by the present invention is: The cam is adapted to engage the cam body of the electrode connector and to engage the camming member with the cam body being rotatably mounted on the cam body and the camming member being rotatably mounted on the cam body.

[0006] According to the present invention adopting the above-mentioned technical solution, when the plug body is plugged into the electrode connection seat, the card block on the rotary lock buckle is carded into the card slot on the electrode connection seat, and the card engagement force of the two makes the connection between the plug body and the electrode connection seat more firm and reliable and not easy to fall off compared with the prior art; at the same time, due to the abutment effect of the end of the elastic member, even if the rotary lock buckle is rotated by an external force, after the external force is removed, the rotary lock buckle will be reset to the card engagement state with the electrode connection seat, so the connection between the plug body and the electrode connection seat is stable and reliable; when it is necessary to pull out the electrode plug, by pulling the movable sleeve, the rotary lock buckle can be driven to rotate until the card block is disengaged from the card slot, and then it can be pulled out, which is convenient and quick to operate; compared with the problem that the connection reliability between the electrode plug and the electrode connection seat of the defibrillator in the prior art is insufficient, when the wire is accidentally pulled, it is easy to cause the electrode plug to have poor contact or fall off, delaying emergency treatment, the connection structure between the electrode plug and the electrode connection seat in the present invention is more firm and reliable, when the wire is accidentally pulled, it will not cause the electrode plug to have poor contact or fall off, ensuring timely emergency treatment.

[0007] Furthermore, the guide bevel is provided on the side of the card block facing the electrode connecting seat; during the process of inserting the plug body into the electrode connecting seat, the electrode connecting seat abuts against the guide bevel and pushes the rotary lock to rotate and compress the elastic member; when the plug body is plugged into place, the rotary lock rebounds until the card block is engaged in the card slot; by providing the guide bevel on the card block, when installing the electrode plug, the plug body is pressed down, the electrode connecting seat abuts against the guide bevel, pushing the rotary lock to rotate, and the elastic member is compressed. When the plug body and the electrode connecting seat are plugged into place, under the action of the elastic member, the rotary lock rebounds, the card block is engaged with the card slot, and the electrode plug is installed, and the operation is convenient and quick.

[0008] Furthermore, the rotary lock is block-shaped, and a rotating shaft and the blocking block are respectively provided at two opposite ends of the rotary lock, and the rotary lock is rotatably installed on the side of the plug body through the rotating shaft, and the blocking block is arranged on the side of the rotary lock away from the plug body; the two ends of the elastic member respectively abut the side of the plug body and the side of the rotary lock close to the plug body; the end of the plug connecting socket close to the electrode plug is the connecting end, the plug body is inserted into the connecting end, and the blocking groove is arranged on the inner wall of the connecting end.

[0009] Furthermore, a receiving groove is provided on the side of the plug body, the rotary lock is rotatably installed in the receiving groove, and the clamping block extends out of the receiving groove; such an arrangement reduces the volume of the overall structure.

[0010] Furthermore, the plug body includes a first bracket and a second bracket that are fixedly connected, and the first bracket and the second bracket together form the accommodating groove and the rotating shaft slot for accommodating the rotating shaft; such a configuration facilitates the installation of the rotating lock and its rotating shaft.

[0011] Furthermore, the number of the rotary locks is one or more; when the number of the rotary locks is multiple, they are evenly arranged circumferentially on the side of the plug body; multiple rotary locks can be set to ensure the connection reliability between the electrode plug and the electrode connecting socket.

[0012] Furthermore, a limiting groove is provided on the outer wall of the plug body, and a limiting slider is provided on the inner wall of the movable sleeve. The limiting slider can be axially slidably installed in the limiting groove, and the opposite end surfaces at both ends of the limiting groove are used to limit the sliding range of the limiting slider; the axial movable range of the movable sleeve on the socket body is limited by the above structure, thereby preventing the movable sleeve from falling off the socket body.

[0013] To achieve the second purpose, the present invention adopts the following technical solution: A defibrillator comprises a main unit and a defibrillation electrode plate, and also comprises the above-mentioned electrode plug connection structure with an anti-detachment function, wherein the electrode connection seat is fixedly mounted on the main unit, and the electrode plug is connected to the defibrillation electrode plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the connection structure between the electrode plug and the electrode connecting socket is more firm and reliable, and when the wire is accidentally pulled, it will not cause poor contact or fall off of the electrode plug, thereby ensuring timely emergency treatment; a movable sleeve is provided, and when it is necessary to pull out the electrode plug, the movable sleeve can be pulled to drive the rotating lock to rotate until the card block and the card slot are disengaged, and then the plug can be pulled out, which is convenient and quick to operate; when installing the electrode plug, only the plug body needs to be pressed down, and after it is plugged into the electrode connecting socket, the card block and the card slot will automatically clamp, which is convenient and quick to operate; the defibrillator has the same technical effect as the aforementioned connection structure.
