Description

Technical Field

[0001] This utility model relates to the technical field of ankle bracelets, and more particularly to a fixing device, an ankle bracelet device and system for preventing mental patients from escaping, for use by mental patients. Background Technology

[0002] Patients with mental illness, especially those with severe mental illness or in an acute phase, often pose a risk of running away, self-harm, or harming others. This not only threatens the safety of the patients themselves and those around them, but also presents significant management challenges for medical and nursing staff.

[0003] In recent years, electronic monitoring equipment has been gradually applied in the management of mental illness patients. For example, GPS-based trackers can monitor the patient's location in real time. However, most existing electronic monitoring equipment lacks effective immediate intervention methods. Once a patient is found to have escape tendencies, manual intervention is often the only option, which is slow and difficult to effectively stop the escape, while also consuming significant manpower and resources. Furthermore, some mental illness patients exhibit violent behavior during episodes, such as fighting, endangering the safety of others. Although some monitoring devices are attached to the patient's clothing to detect aggressive behavior, medical staff may not be able to locate the patient in time, and injuries may have already occurred by the time they are found. Additionally, caregivers face the risk of being attacked themselves while trying to stop the patient's aggressive behavior.

[0004] Some existing ankle bracelets only have monitoring functions and cannot intervene in the patient's behavior. Moreover, their structure is often complex, making them inconvenient to wear and affecting the patient's daily life.

[0005] To address the problems in existing technologies, such as the inability to promptly detect or stop patients from escaping or attacking others, and the inconvenience of wearing ankle bracelets due to their complex structure. Utility Model Content

[0203] How to use this utility model:

[0204] (a) Locking

[0205] When locked, the third fixing element 1031 is in a fixed state; the pushing pressing element 1051 moves along the first sliding element 1012 toward the first fixing element 1011, and drives several eighth sliding elements 1054 to slide relative to the corresponding several second sliding elements 1014. The second fixing element 1021 moves closer to the third fixing element 1031. Several second locking elements 1041 respectively enter the corresponding fourth sliding element 1024 and second sliding element 1014, and abut against the bottom end of the second stop element 1055. The first movable element 1052 pushes several first locking elements 1025 to slide on the corresponding fourth sliding element 1024 and separate them from each other, so that the first locking elements 1025 respectively lock the corresponding second locking elements 1041. The first reset element 1029 is in an open state, and the second movable element 1053 enters the seventh sliding element 1032.

[0206] (II) Unlock

[0207] Pulling the pressing element 1051 away from the first fixed element 1011 causes the first movable element 1052 to move upward. The first stop element 1015 restricts the position of the second stop element 1055 to prevent the eighth sliding element 1054 from sliding out of the corresponding second sliding element 1014. The first movable element 1052 separates from the first locking element 1025, the first reset element 1029 retracts, and several sixth sliding elements 1027 slide relative to the corresponding fifth sliding elements 1026. Several first locking elements 1025 converge to release the lock on the second locking element 1041, and the second locking element 1041 slides out of the second sliding element 1014 and the fourth sliding element 1024.

[0208] The technical effects of this utility model are as follows: by using the movable unit to set up a structure with different upper and lower radial dimensions, and slidingly connecting it with the second fixed unit to change the state of the second fixed unit, the second fixed unit can be locked or unlocked with the locking unit. This not only easily fixes the relative positions of the first fixed unit, the second fixed unit, and the third fixed unit, making them less likely to detach, but also makes disassembly simple and convenient.

[0300] In some embodiments, the power supply element 2073 is a battery, including but not limited to a lithium battery.

[0301] The usage method of this embodiment is as follows:

[0302] (a) Ankle ring fixation

[0303] In use, the wearable element 2011 is first placed on the patient's ankle, and the third mounting element 2051 is placed between the first mounting element 2031 and the second mounting element 2041. Then, the second movable element 1053 and the first movable element 1052 are slidably connected to the ninth sliding element 2032 and the eleventh sliding element 2052, respectively. At the same time, the first limiting element 1016 slides relative to the second limiting element 2033 and the third limiting element 2053 until the second fixing element 1021 and the third fixing element 1031 abut against each other. Following the steps of Embodiment 1, the second locking element 1041 is locked to the first locking element 1025. The bottom end of the second movable element 1053 is slidably connected to the tenth sliding element 2042, and the second magnetic element 2043 is locked to the first magnetic element 1056. The wearable element 2011 is then fixed to the patient's ankle.

[0304] (II) Pulsed Current Stimulation

[0305] The positioning unit 2060 monitors the patient's location information in real time. When the patient's location is detected to be outside the preset range, the control system determines that the patient is about to escape. Or, when the control system detects that the patient is about to escape or commit violence against others, the control system controls the first voltage conversion element 2022 and the first output element 2024 to output low-voltage current, and controls the second voltage conversion element 2023 and the second output element 2025 to output high-voltage current, thereby stimulating the patient with a brief pulse current to cause leg muscle pain or spasm, temporarily losing the ability to move, thereby interfering with the patient's behavior of attacking others or escaping.

[0306] (III) Unlock

[0307] When the ankle bracelet needs to be replaced or recharged, a strong magnetic disassembly device is used to disconnect the second magnetic element 2043 from the first magnetic element 1056, and the locking connection between the second locking element 1041 and the first locking element 1025 is released using the method and steps of Embodiment 1. The fixing device 1000 is then separated from the second mounting element 2041, the third mounting element 2051 and the first mounting element 2031 in succession, thereby releasing the wearable element 2011.

[0308] The technical effects of this embodiment are as follows: By using a positioning unit to monitor the patient's location information and connecting the central control unit to the control system, when the patient attempts to escape or attacks others, the pulse stimulation unit can be automatically controlled to stimulate the patient's legs with pulse current. This can effectively and promptly prevent the patient from escaping or attacking others and causing injury, solving the problem of not being able to stop the patient from escaping or attacking others in time. Furthermore, by using the first mounting unit, the second mounting unit, the third mounting unit, and the fixing device in conjunction, it has an anti-disassembly function. It can not only easily fix the wearable unit to the patient's leg to prevent the patient from disassembling it, but also does not affect the patient's daily activities, solving the problem of the inconvenience of wearing the complex structure of the anklet.

[0321] In some embodiments, the reinforcing element 2081 is a soft metal wire, including but not limited to stainless steel wire.

[0322] The technical effects of this embodiment are as follows: the reinforcement unit can effectively prevent patients from damaging the wearable unit and can extend the service life of the wearable unit.

[0328] In some of these embodiments, the first warning element 2091 includes, but is not limited to, a flashlight.

[0329] Furthermore, the warning unit 2090 also includes a second warning element 2092. The second warning element 2092 is disposed in the wearable unit 2010 and connected to the central control unit 2070, and is used to provide an audible warning when the patient is stimulated.

[0330] Specifically, the second warning element 2092 is disposed on the protection element 2021 and connected to the central control element 2071.

[0331] In some of these embodiments, the second warning element 2092 includes, but is not limited to, a speaker.

[0332] The usage method of this embodiment is as follows:

[0333] When the control system controls the pulse stimulation unit 2020 to provide pulsed current stimulation to the patient, or detects that the patient is trying to escape or attack others, it simultaneously controls the first warning element 2091 and the second warning element 2092 to provide an alert, so as to help staff quickly find the patient and take timely remedial measures.

[0334] The technical effects of this embodiment are as follows: By using the warning unit, a timely warning can be given when the patient exhibits escape behavior, attacks others, or is subjected to pulsed current stimulation. This alerts the patient or helps staff quickly locate the patient's position and take timely remedial measures, effectively preventing the situation from worsening and solving the problem of patients not being detected in time when they escape or attack others.

[0340] More specifically, the remote control device 3000 is communicatively connected to the central control element 2071.

[0341] The method of use in this embodiment is as follows: When the remote control device 3000 detects that the patient is attacking others through other monitoring devices, or when it detects that the patient is trying to escape through other monitoring devices, it matches the positioning information of the positioning unit 2060. If the escape is confirmed, the central control element 2071 automatically controls the pulse stimulation unit 2020 to stimulate the patient with pulse current.

[0342] The technical effects of this embodiment are as follows: By using a remote control device, the patient's behavior can be monitored from multiple angles, and the pulse current stimulation can be automatically controlled to be applied to the patient, resulting in a more timely and effective response.
