Description

First-aid hemostatic bandage

Technical Field

The utility model belongs to a medical emergency apparatus, in particular to an emergency hemostatic bandage. It is suitable for first-aid hemostasis in the battle (field), disaster site or in front of hospital.

Background

Hemorrhage is often caused by war hour and peacetime trauma, and the data analysis of the first-aid injury condition of Yilac Afghanistan combat of the Med army finds that the major hemorrhage, the tension pneumothorax and the airway obstruction are lethal factors which can be saved in the combat field, wherein the major hemorrhage accounts for about 60 percent. Therefore, the hemostatic bandaging is an important technical means for stabilizing the injury and reducing the death rate in the pre-hospital emergency or the war (present) emergency. Meanwhile, the wound surface is firmly bound, so that further pollution can be prevented, and infection can be initially prevented. At present, the conditions of military and civil bandaging equipment in China are as follows: the function is single, the dressing is separated from the bandage, the dressing speed is slow, and the operation is time-consuming and labor-consuming; although the dressing such as the military triangle towel first-aid kit, the bandage type first-aid kit and the like is combined with the triangle towel or the bandage, the triangle towel and the bandage are made of non-elastic cloth, and the static pressure is low, so when the triangle towel or the bandage is used for hemostasis or fracture fixation, the phenomenon of looseness or even looseness can occur along with the time. Has no water resistance, is easy to wet in a rainwater environment or during emergency treatment in water operation, and harmful substances or microorganisms in water can permeate into the wound surface along with water.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, the emergency hemostatic bandage comprises a main dressing pad 1, a movable dressing pad 2, a bandage 3, an outer port indicator strip 4 and a hasp rod 5, wherein the outer port indicator strip 4 and the hasp rod 5 are respectively positioned at two opposite ends of the bandage 3, the main dressing pad 1 is fixed on the bandage 3 at a position 15cm-35cm away from the outer port indicator strip 4, the fixing mode can be fixed on the bandage 3 through a sewing process or sleeved on the bandage 3 in a sleeve mode, the position of the main dressing pad 1 fixed on the bandage 3 can be properly adjusted along the length direction of the bandage 3, and the size of the main dressing pad 1 can be set into different specifications according to needs. In this embodiment the removable dressing pad 2 is a separate piece that can be used depending on whether the wound is through or if it is desired to pack the wound. The bandage 3 is made of a self-adhesive elastic material which is made of spandex or a textile woven with spandex yarns, and the surface of the spandex is sprayed with natural latex particles or polyacrylate adhesive particles. Any position of the bandage 3 can be torn off by hand. In this embodiment, the bandage 3 has a rectangular frame 32 which is different in color from the body of the bandage and which can display the stretch ratio, and the stretch ratio of the bandage and the pressure generated can be preliminarily determined by changing the shape of the rectangular frame 32. The end of the bandage 3 close to the outer port indicating strip 4 is also provided with a fixing hole, when in use, the fixing hole 31 can be sleeved on the finger, the wrist, the toe and the ankle, the self-adhesive elastic bandage has elasticity, and the hole can be enlarged. As shown in fig. 5, after the bandage is wound, the clip 51 of the buckle bar 5 can be used to hold any wound bandage, and the anti-loosening thorn-shaped protrusion 52 can further improve the fixing effect of the bandage end.

As shown in fig. 2, the bandage roll outer port is not provided with a pressure indicating line.

As shown in fig. 3, the main dressing pad 1 comprises a wound contact layer 11, an exudate absorption layer 12 and a hydrophobic barrier layer 13, wherein the wound contact layer 11 is made of natural biological materials. The wound contact layer 11 is made of a material having a function of inducing blood coagulation, such as chitosan fiber, calcium alginate fiber, collagen, modified starch, and other natural biomaterials, but not limited to the above materials. The exudate absorbing layer 12 is made of highly hygroscopic fiber such as absorbent cotton, viscose fiber, calcium alginate fiber, and highly water-absorbent resin fiber, but not limited thereto. The hydrophobic barrier layer 13 is a thermoplastic polyurethane film or hydrophobic ethylene-propylene fiber, but is not limited to the above materials.

The three-layer structure is sewn into a whole through a sewing process or the three layers are compounded through a needle-punched non-woven fabric process. In this case, the hydrophobic barrier layer 13, i.e. the outer layer, lies against the surface of the bandage 3. The main dressing pad can be threaded or sewn directly onto the bandage. The advantage of wearing the fixed mode of cover lies in can adjusting main dressing pad position according to the position of injury, and the advantage of making up fixed mode lies in wrapping up more firmly.

As shown in fig. 4, the movable dressing pad 2 is in the case of two wound contact layers 11. The wound contact layer 11 is made of natural biological materials. The two surfaces of the movable dressing pad 2 are wound contact layers 11, and the wound contact layers 11 are made of natural biomaterials, such as chitosan fibers, calcium alginate fibers, silk fibroin films and the like, but not limited to the above materials.

The removable dressing pad 2 may also be used for cover dressing across the wound surface on either side of the wound. The movable dressing pad is a single-layer or multi-layer wound contact layer 11, and a exudate absorption layer can be compounded in the contact layer. The movable dressing pad can be an independent piece and can also be sleeved on the bandage belt body in a penetrating way.

The sizes of the main dressing pad 1 and the movable dressing pad 2 are set into different specifications according to the size of the wound surface.

The above-mentioned embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention, and the present invention is not limited by the design concept of the present invention, and the technical solutions of the present invention are all suitable for various modifications and improvements made by the technical personnel in the field.
