AI Technical Summary
Drowning accidents occur frequently in primary and secondary school students and tourists in the waters, and the existing technology lacks effective prevention and rescue measures, resulting in frequent drowning tragedies.
A wearable buoyancy sheet and buoyancy backpack are designed. The buoyancy sheet is composed of pearl cotton sheets and waterproof membrane cloth bags, and is equipped with elastic straps to facilitate wear on the chest; the buoyancy backpack is embedded in the backpack to provide additional buoyancy and rescue tools.
By wearing buoyancy tablets or backpacks, users can gain buoyancy in the water and avoid drowning; at the same time, buoyancy backpacks provide a new rescue method, where rescuers throw buoyancy backpacks to those who fall into the water without going into the water, improving rescue efficiency and safety.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anti-drowning life-saving, and particularly relates to a wearable buoyancy sheet and a buoyancy backpack. Background Art
[0002] Drowning accidents among primary and middle school students occur from time to time. Some are due to falling into the water during school or play, and some are caused by drowning while playing in waters without supervision.
[0003] When people travel and relax, drowning incidents also occur from time to time, especially among underage tourists who play in the water or accidentally fall into the water.
[0004] When a drowning accident occurs, classmates, family members or those who act bravely for a just cause often rescue the drowning person without considering their own safety, resulting in multiple drowning tragedies.
[0005] After a drowning accident occurs, there are rarely any rescue equipment at the scene, which always makes people feel helpless and heartbroken. Summary of the Invention
[0006] In order to reduce drowning accidents, the purpose of the utility model is to provide a wearable buoyancy sheet and a buoyancy backpack. The wearable buoyancy sheet is worn on the body when playing in a safe water area to prevent drowning; the buoyancy backpack provides buoyancy in case of accidental falling into the water to prevent drowning.
[0007] A wearable buoyancy sheet of the utility model includes a buoyancy sheet and a fastening strap. The buoyancy sheet includes an EPE sheet and a waterproof membrane cloth bag for wrapping the EPE sheet. A buttonhole is provided on each of the two sides of the waterproof membrane cloth bag, and the fastening strap is threaded through the buttonholes.
[0008] The wearable buoyancy sheet of the utility model is used as follows: when playing in a safe water area or practicing swimming in a swimming pool, to prevent accidents, the buoyancy sheet can be worn on the chest through the fastening strap. When accidentally entering a deep water area, hold the buoyancy sheet in front of the chest with both hands, and the buoyancy sheet provides buoyancy to avoid drowning.
[0009] Further, the waterproof membrane cloth bag includes three chambers. The middle part is a cavity for the EPE sheet, and the left and right ends are air chambers. The air chambers at both ends are communicated with the middle cavity, and the whole waterproof membrane cloth bag is an airtight cavity. An inflation nozzle is installed on the waterproof membrane cloth bag; the waterproof membrane cloth bag can be inflated through the inflation nozzle.
[0010] Further, the waterproof membrane cloth bag is made of TPU membrane cloth by heat sealing.
[0011] The present utility model also provides a buoyancy backpack, which includes a backpack and the wearable buoyancy sheet of the present utility model. A back pocket is provided on the back of the backpack, and the wearable buoyancy sheet is installed in the back pocket; further, the opening of the back pocket is at the lower part, and the opening is switched by a zipper or a magic tape.
[0012] The buoyancy backpack of the present utility model is used as follows. When accidentally falling into the water during school or play, hold the backpack in front of the chest. After multiple underwater tests, when one hand grabs the shoulder strap of the backpack at the shoulder position and lifts the backpack upward, the other hand grabs the side of the backpack and flips it to the front of the chest and hugs it tightly. This method is the simplest and quickest. The shoulder straps of the backpack can remain on the arms, improving safety and reliability. After holding the backpack in front of the chest, if there are heavy objects with a large density in the backpack, open the backpack with one hand and take out the heavy objects and throw them away. The wearable buoyancy sheet in the backpack provides buoyancy to avoid drowning; more often, when someone else falls into the water, take out the heavy objects in the backpack and throw the buoyancy backpack to the drowning person for rescue. The rescuer does not need to enter the water, providing a new way for rescuing drowning people and being able to save more lives.
[0013] A wearable buoyancy sheet of the present utility model includes a buoyancy sheet and a fastening strap. The buoyancy sheet includes an EPE sheet and a waterproof membrane bag for sleeving the EPE sheet. The fastening strap is threaded through the buckle holes on both sides of the waterproof membrane bag. Before playing in the water, the buoyancy sheet can be worn on the chest through the fastening strap. The buoyancy sheet provides buoyancy to avoid drowning, and is simple and convenient to use; the present utility model also provides a buoyancy backpack, with a back pocket provided on the back of the backpack, and the wearable buoyancy sheet is installed and stored in the back pocket. When accidentally falling into the water, hold the backpack in front of the chest, and the wearable buoyancy sheet in the backpack provides buoyancy to avoid drowning. When someone else falls into the water, take out the heavy objects in the backpack and throw the buoyancy backpack to the drowning person for rescue. The rescuer does not need to enter the water, providing a new way for rescuing drowning people and being able to save more lives. Description of the Drawings
