[0002] Falling is the number one killer of accidental injuries to the elderly. There are a large number of elderly people falling in our country every year. The consequences are very serious if the elderly cannot receive treatment after falling. For this reason, there are various elderly fall alarms on the market, which are used to give an alarm after the elderly fall, attract the attention of outsiders and provide help, and the fall alarms play a positive role. The fastest rescue after the elderly fall is the best solution to avoid more serious post-injury. The working principles of various elderly fall alarms on the market are to judge whether the elderly fall by the information collected by an electronic detector or a sensor, and then the command controller controls whether to activate the alarm. It has the following deficiencies: 1. The more electronic components, the higher the cost; 2. The accuracy of the information detected by the electronic detector or collected by the sensor is affected by various factors. Whether the accuracy is accurate or not directly affects the actual use effect; 3. In reality, the qualification rate of no component reaches 100%. The combined qualification rate of multiple components is even lower. In theory, the more electronic components, the higher the probability of failure; Content of the Utility Model

[0003] In order to overcome the above deficiencies of the existing elderly fall alarms, the utility model provides a wearable elderly fall alarm. This alarm is worn on the waist or arm of the elderly, and uses the sliding of the conductive metal beads in the trigger to control whether to activate the alarm. When the elderly person falls, the conductive metal beads in the trigger slide under the action of the kinetic energy generated during the fall or the gravity of the conductive metal beads, so that the two contacts of the trigger are connected, thereby turning on the power supply of the alarm unit and giving an alarm. The alarm forms are: sound alarm, light alarm or a combined alarm of sound alarm and light alarm, so as to attract the attention of outsiders and provide help, so that the fallen elderly can get the fastest rescue. The greatest truth is the simplest. A simple and direct technical solution is the most reliable.

[0004] The technical solution adopted by the present utility model to solve its technical problems is as follows: A wearable elderly fall alarm, comprising: a housing, an alarm unit, a power cord, a battery, and a trigger. The characteristics are: the alarm unit, the power cord, the battery, and the trigger are installed in the housing. The alarm unit, the battery, and the trigger are connected by three power cords. One power cord connects the alarm unit and the battery, the second connects the battery and contact point two, and the third connects contact point one and the alarm unit. The trigger is responsible for controlling whether the alarm unit emits an alarm, and the battery is responsible for providing electrical energy; the trigger consists of: a housing, contact point one, contact point two, and a conductive metal bead. Contact point one, contact point two, and the conductive metal bead are installed in the housing. Contact point one and contact point two are in an open state under normal circumstances or when the elderly do not fall. The conductive metal bead can slide within the designed range. When the elderly fall, the conductive metal bead in the trigger slides under the action of the kinetic energy generated when the elderly fall or the self-gravity of the conductive metal bead, so that the two contact points in the trigger are connected, thereby turning on the power supply of the alarm unit and emitting an alarm. When the elderly get up or are helped up, the conductive metal bead slides under the action of its own gravity, so that the two contact points in the trigger are disconnected, thereby turning off the alarm function; the alarm form of the alarm unit: sound alarm, light alarm, or a combined alarm of sound alarm and light alarm. The battery is a disposable battery or a rechargeable battery.
