Description

Inflatable pressure tourniquet for limbs

technical field

The utility model relates to an inflatable and pressurized tourniquet for limbs, which belongs to the technical field of medical auxiliary appliances.

Background technique

The tourniquet is used to provide bloodless surgical vision in medical emergency or surgery for limb trauma. Its function is to compress the blood vessels of the limb by inflating the air bag, block the blood circulation of the limb, and thus prevent the bleeding of the wound to the greatest extent. At present, when hemostasis is performed on a large area of a limb, a plurality of airbags arranged side by side are generally used to increase the contact area with the limb, so as to achieve the purpose of hemostasis in a large area. However, after the airbag is inflated, the mutually contacting ends of two adjacent airbags cannot be sufficiently fitted, so that the airbag cannot apply pressure to the limb located there, thereby affecting the effect of hemostasis.

Utility model content

Inflate the air bag through the inflation port to make the air bag compress the blood vessels of the patient's limbs, so as to achieve the purpose of hemostasis in a large area. On the end of the other adjacent airbag, after the airbag is inflated, the end of one of the airbags can press against the end of the other adjacent airbag, so that the ends of the two adjacent airbags that are in contact with each other can fit more fully, so as to The contact area between the end of the airbag and the limb is increased, so that the airbag can apply pressure to the limb located at the end of the airbag, and can effectively reduce the area on the limb that cannot be pressed, thereby ensuring the effect of hemostasis.

Preferably, the two ends of the two adjacent airbags overlap each other after being inflated to form a right-angled triangular prism structure respectively, and the inclined surfaces formed by the two ends are in contact with each other.

By forming a right-angled triangular prism structure at the two ends of the two adjacent airbags overlapping each other, and the inclined surfaces formed at the two ends are in contact with each other, the ends of the two adjacent airbags that are in contact with each other can fit more fully. In order to ensure the effect of hemostasis, and to make the two overlapping ends of two adjacent airbags contact each other through inclined surfaces, so that they have a larger contact area, so as to ensure that the ends of the airbags have sufficient pressure after inflation.

Preferably, a Velcro is provided between the inclined surfaces of the two ends of the two adjacent airbags overlapping each other to realize the bonding and fixing.

By providing a Velcro between the inclined surfaces of the two overlapping ends of the two adjacent airbags to realize the bonding and fixing, the two overlapping ends of the two adjacent airbags can be kept in a fully attached state. , for stable compression of the patient's limb.

Preferably, the angles and directions of the inclined surfaces of the end portions of each of the airbags are the same.

By arranging the same angle and orientation of the slope of each air bag end, the pressure of each air bag end can be made approximately the same, so as to apply even pressure to the patient's limb.

Preferably, the fixing structure includes two straps disposed on opposite sides of the tourniquet body in the width direction, the straps include a connection end fixed to the width end of the tourniquet body and a free end extending outward, one of which is One of the straps is sleeved with a locking buckle for adjusting the length of the strap, and the free end of the other strap is fixed with a connecting buckle for inserting and fixing with the locking buckle to connect the two straps. The free ends are snapped together.

By having two straps disposed on opposite sides of the tourniquet main body in the width direction in the fixing structure, the strap includes a connection end fixedly connected with the width end of the tourniquet main body and a free end extending outward, wherein one strap The upper sleeve is provided with a locking buckle for adjusting the length of the strap, and the free end of the other strap is fixed with a connecting buckle for inserting and fixing with the locking buckle to fasten the free ends of the two straps together. , so that the free ends of the two straps can be fastened to each other through the plug-in cooperation of the locking buckle and the connecting buckle, so that the tourniquet main body can be fixed on the patient's limb, and the length of the strap can be adjusted to be suitable for different patients to achieve the best hemostatic effect.

Preferably, the inflation port is provided with a control valve, and the airbag is provided with an air pressure monitor.

By having a control valve on the inflation port and an air pressure monitor in the air bag, the air bag can be inflated and deflated by controlling the opening and closing of the valve. can be replenished in time.

Therefore, the present invention can make the ends of two adjacent airbags in contact with each other fit more fully, so as to increase the contact area between the end of the airbag and the limb, so that the airbag can press the limb located at the end of the airbag. , and can effectively reduce the area on the limb that cannot be pressed, so as to ensure the effect of hemostasis and other advantages.
