2. Description of the Related Art
At present, ships are usually equipped with lifesaving devices, such as life buoys and life jackets for use by individuals, or life rafts and lifeboats for use by more than one person. The above lifesaving devices have the following disadvantages:
(1) The life buoy or life jacket used by individuals can only prevent a person who falls into water from sinking, without insulating the person from the cold water which can freeze the person to death if the time before rescue is too long;
(2) The life raft used by more than one person is difficult to be equipped onto a small ship. In addition, the life raft should be operated by a skilled person. Thus, when a marine disaster happens, the life raft tends to be overturned due to incorrect manipulations in emergency or stormy ocean wave circumstance;
(3) Marine search and rescue is difficult because the above lifesaving devices are usually moved far away from the disaster place by the storm and wave at ocean.
The present invention provides a heat-retaining lifesaving appliance which overcomes the disadvantages of the conventional life buoys and life jackets, such as a rescuee is immersed directly into cold water or is suffocated, to enable one person can rapidly operate the heat-retaining lifesaving appliance of the present invention to save himself or herself.
In order to achieve the above objects of the present application, a heat-retaining lifesaving appliance is provided. It comprises a spherical helmet, a life buoy and a heat-retaining sack body which are integrally sealed. The heat-retaining sack body comprises an external surface layer and an internal layer. A waterproof zip is provided on the heat-retaining sack body and the spherical helmet, respectively, and an air inflation spout is provided on the heat-retaining sack body and the life buoy, respectively. The life buoy is provided between the spherical helmet and the heat-retaining sack body, and the spherical helmet is provided thereon with a sight glass and a breathing cap.
In the heat-retaining lifesaving appliance, the breathing cap comprises an indicating lamp cover, a breathing tube and an air inlet. The air inlet is provided with a one-way valve comprising two ball floats, and the breathing tube is connected to a breathing nozzle.
In the heat-retaining lifesaving appliance, the spherical helmet is provided therein with a distress-call signal generator, a breathing nozzle connected to the breathing cap, and a discharging valve for discharging expiration.
In the heat-retaining lifesaving appliance, the heat-retaining sack body is cylindrical or in a shape of one-piece garment.
In the heat-retaining lifesaving appliance, the air inflation spout comprises an internal air inflation spout and an external air inflation spout.
Furthermore, the external surface layer and internal layer of the lifesaving appliance are made of bonded waterproof cloth, with air inflated therebetween. The sight glass is made of Perspex. The breathing cap has a function of providing fresh air for users, and the expiration is discharged through the discharging valve. The breathing cap is made of PVC (polyvinyl chloride) and is provided at the top end thereof with a red indicating lamp cover which is made of Perspex. The one-way valve that comprises plastic ball floats is provided in the two air inlets of the breathing cap. The breathing tube is made of rubber and the breathing nozzle for breath is made of plastic rubber.
When in use, a valve of an air inflation steel cylinder which is connected to the air inflation spout is firstly opened, or a manual air inflation apparatus can also be used. Then the external surface layer, the internal layer and the life buoy are inflated. The steel cylinder is thrown away when the heat-retaining sack body is completely inflated. Then the user puts on the heat-retaining lifesaving appliance with his back toward the waterproof zip, steps into the appliance and squats himself down. Subsequently, the zip on the chest and the helmet is zipped on. When the zip is zipped on completely, two metal pieces at the end of the zip come into contact with each other, meanwhile, the distress-call signal generator and the red indicating lamp are turned on synchronously. Then the user can hold the breathing spout in mouth and jump into the sea water.
In the case of using a heat-retaining lifesaving appliance having a sack body in a shape of one-piece garment, the user can stand astraddle at the middle of the life buoy and inflate the appliance with an air inflation steel cylinder. The steel cylinder is thrown away when the heat-retaining sack body is completely inflated. Then the user zips on the zip on the chest and the helmet, holds the breathing spout in mouth and jumps into the sea water.
The user can also perform inflation through the internal air inflation spout.
The heat-retaining lifesaving appliance of the present invention has the following advantages:
(1) Individuals can save themselves rapidly when a disaster happens;
(2) The rescuee does not contact with water directly. In addition, an air isolation layer is present and the person in the appliance is in a squatting posture. Thus the area of dissipation is decreased;
(3) The automatic distress-call signal generator and the red indicating lamp on the spherical helmet facilitate the marine search and rescue. Thus the present invention is especially suitable for use by aged people and children.
