Description

Technical Field

[0001] This invention relates to the field of catheter anti-dislodgement technology, specifically to an alarm device for preventing accidental catheter removal. Background Technology

[0002] In current clinical nursing practice, patients with indwelling catheters such as gastric tubes, drainage tubes, and central venous catheters often accidentally pull out their tubes due to confusion, restlessness, or unconscious behavior during sleep. This can lead to serious medical complications, prolonged hospital stays, and even threaten the patient's life.

[0003] Existing methods for preventing tube removal mainly rely on physical restraints, increased patrols, or the use of simple fixing devices. However, these methods either raise ethical and comfort issues or fail to provide timely and proactive alarms, often only being discovered after the tube removal incident has occurred, thus missing the best opportunity for intervention.

[0004] Therefore, an alarm device to prevent accidental pipe pulling is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an alarm device to prevent accidental pipe pulling, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an alarm device for preventing accidental pipe pulling, comprising a pull rope, a flexible patch and a mounting box, wherein a wireless transmission module is fixedly connected to the inner bottom wall of the mounting box, a buzzer is installed inside the mounting box, and a microprocessor is installed inside the mounting box.

[0007] Preferably, the flexible patch is arranged in three layers, one above the other. The outer side of the flexible patch in the middle layer is provided with a miniature socket, and the outer side of the mounting box is provided with a male connector. The miniature socket and the male connector are inserted into each other. Both the mounting box and the flexible patch are gourd-shaped designs, and the mounting box is flexible and bendable.

[0008] Preferably, the non-adhesive surface of the flexible patch is provided with a microelectrode sensor array for monitoring its contact state with the skin, and the flexible patch is electrically connected to the wireless transmission module.

[0009] Preferably, the microprocessor is internally electrically connected to the wireless transmission module. The microprocessor is configured to receive and process the sensing signals of the microelectrode sensing array. The wireless transmission module mainly receives signals from the flexible patch. When the flexible patch is normally attached to the patient's body, the wireless transmission module receives a positive signal. When the flexible patch is detached from the patient's body, the wireless transmission module receives a negative signal.

[0010] Preferably, the microprocessor is electrically connected to the buzzer. When the wireless transmission module receives a negative signal and transmits it to the microprocessor, the microprocessor controls the buzzer to sound an alarm.

[0011] Preferably, an adhesive patch is provided on the side of the pull cord away from the flexible patch. The adhesive patch is made of a flexible material and can be attached to the medical tubing.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] This invention achieves continuous monitoring of the device's own bonding status through flexible patches and their integrated microelectrode sensing array, providing an important preventive early warning function. The microprocessor's real-time analysis of the impedance signal of the microelectrode array can sensitively identify different bonding failure modes such as patch edge lifting and center detachment, and issue an early warning before the pipeline is actually pulled, thereby upgrading passive alarm to proactive risk prevention. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the overall structure of the present invention.

[0015] The components include: 1. pull rope; 2. mounting box; and 4. flexible patch. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This invention provides the following technical solutions:

[0018] Please see Figure 1 An alarm device for preventing accidental pipe pulling includes a pull rope 1, a flexible patch 4, and a mounting box 2. A wireless transmission module is fixedly connected to the inner bottom wall of the mounting box 2. A buzzer is installed inside the mounting box 2, and a microprocessor is installed inside the mounting box 2.

[0019] The flexible patch 4 consists of three layers arranged vertically. The outer side of the middle layer flexible patch 4 is equipped with a miniature socket, and the outer side of the mounting box 2 is equipped with a male connector. The miniature socket and the male connector are connected. Both the mounting box 2 and the flexible patch 4 have a gourd-shaped design. The mounting box 2 is flexible and bendable.

[0020] The non-adhesive surface of the flexible patch 4 is provided with a microelectrode sensor array for monitoring its contact state with the skin, and the flexible patch 4 is electrically connected to the wireless transmission module.

[0021] The microprocessor is internally electrically connected to the wireless transmission module. The microprocessor is configured to receive and process the sensing signals of the microelectrode sensing array. The wireless transmission module mainly receives signals from the flexible patch 4. When the flexible patch 4 is normally attached to the patient's body, the wireless transmission module receives a positive signal. When the flexible patch 4 is detached from the patient's body, the wireless transmission module receives a negative signal.

[0022] The microprocessor is electrically connected to the buzzer. When the wireless transmission module receives a negative signal and transmits it to the microprocessor, the microprocessor controls the buzzer to sound an alarm.

[0023] An adhesive patch is provided on the side of the pull rope 1 away from the flexible patch 4. The adhesive patch is made of flexible material and can be attached to the medical tubing.

[0024] The non-adhesive surface of the flexible patch 4 is equipped with a microelectrode sensor array, and a microprocessor is configured to process its sensor signals. By monitoring the change in the contact impedance between the skin and the patch through the electrode array, it can determine whether the adhesive is loose or detached. The microprocessor then analyzes and judges the results, thereby achieving a preventive alarm for adhesive failure.

[0025] In use, medical staff first attach the flexible patch 4 to the patient's skin and connect it to the male connector on the outside of the mounting box through the micro socket on it. In the event of accidental tube removal, the microprocessor immediately drives the buzzer to sound an alarm.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
