Description

Technical Field

[0001] The invention relates to the field of restraint belt anti-injury, in particular to an inflatable anti-loosening restraint belt. Background Art

[0002] For patients who are agitated, unconscious, have Alzheimer's disease, and are unable to cooperate with treatment and care, restraint belts are needed to prevent patients from hurting themselves, removing infusion tubes, gastric tubes, urinary catheters and other tubes, and tearing off ECG monitoring electrodes, which will affect further treatment and care. At present, the restraint belt is directly fixed on the patient's wrist. When the patient is agitated, it is easy to hurt the wrist because of the strong force. If it is fixed very tightly, although it is not easy to loosen, it is easy to hurt the patient and strangle the wrist. Therefore, how to protect the wrist while preventing it from loosening is an urgent problem that technicians in this field need to solve. Summary of the invention

[0003] The object of the present invention is to provide an inflatable anti-loosening restraint belt to solve the problems raised in the above background technology.

The airbag has toughness and can protect the wrist.

[0005] Preferably, the opening side of the fixing portion is connected by Velcro to achieve fixation. It can also be used in combination with a buckle, using existing technology, which will not be described in detail.

[0006] Preferably, the pressure regulating mechanism comprises an air tube connected to the airbag and an inflation joint arranged at the end of the air tube, and a switch is arranged on the air tube. When the switch is turned on, the air is inflated and deflated through the joint, which can be connected in the form of a syringe or in other forms.

[0007] Preferably, the airbag is annular in shape, which has a large contact area.

[0008] Preferably, the airbags are in the shape of strips arranged front and back, and a plurality of airbags are arranged at equal intervals and fixed on the inner side of the fixing part, and the airbags are connected by connecting pipes to achieve ventilation. The airbags arranged at intervals have better air permeability.

[0009] Preferably, it also includes an inflation mechanism disposed between the fixing portion and the belt body, and the inflation mechanism can inflate the airbag when the fixing portion is pulled to prevent a gap between the airbag and the wrist from being loosened. When the patient is agitated, the inflation mechanism can inflate the airbag, so that the airbag hardness is increased, the fixing force is increased, and it is not easy to produce a gap, thereby preventing loosening.

[0010] Preferably, the inflation mechanism comprises a piston mechanism disposed between the fixing portion and the belt body, and the piston mechanism is connected to the airbag via a conduit. The piston mechanism can inflate the airbag when pulled.

[0011] Preferably, the piston mechanism includes a piston cylinder and a piston block inserted in the piston cylinder, the piston cylinder is connected between the fixed part and the belt body, and the piston cylinder is open at one end close to the belt body, the piston block is connected to a piston rod passing through the bottom of the piston cylinder, and the end of the piston rod is fixedly connected to the fixed part, a piston hole corresponding to the piston rod is provided at the bottom of the piston cylinder, and a sealing ring sleeved on the piston rod is provided on the inner side of the piston hole to ensure sealing, and the conduit is connected to the piston cavity of the piston cylinder.

[0012] Preferably, it also includes a tough baffle plate arranged at the end of the piston rod, and the baffle plate is located on the outside of the piston cylinder and blocks the piston cylinder. The baffle plate prevents the piston cylinder from hurting the hand.

[0013] Preferably, the baffle is in the shape of an airbag, and the baffle is connected to the catheter through a branch tube. When the patient is agitated and pulled, the gas in the piston cylinder is filled into the baffle through the catheter, thereby increasing the hardness and preventing the patient from squeezing the piston cylinder with great force, thereby improving safety. At the same time, the baffle is inflated, the volume increases, the patient's hand movement space is reduced, and the range of hand movement is reduced, thereby reducing danger, avoiding loosening, and protecting the wrist.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The airbag can be inflated to protect the wrist and avoid injury. At the same time, the pressure can be adjusted through the trachea to prevent it from falling off; 2. When the patient is agitated and pulled, the piston block is pulled along with the piston rod and the fixed part, and the airbag is inflated through the catheter to increase the hardness of the airbag, avoid a gap between the airbag and the wrist, and prevent loosening, which not only protects the wrist but also prevents loosening. When the patient stops being agitated, the piston block returns to its position under the pressure of the airbag, thus maintaining a low-pressure comfortable state, thereby achieving both soft and hard states. As the patient's agitation changes, the agitation amplitude is large, the inflation force is large, the hardness of the airbag is increased, and a high-strength anti-loosening state is achieved, the anti-loosening effect is better, and the wrist will not be injured. The agitation stops, the low-pressure state is restored, the comfort level is improved, and the low-pressure state is achieved. The initial pressure can also be adjusted through the trachea.
