Description

An improved first aid hemostasis device

Technical Field

The utility model relates to the technical field of medical supplies, in particular to an improved first aid hemostasis device.

Background technique

Blood is one of the most important components of the human body, accounting for about 8% of an adult's body weight, which is equivalent to 70 to 80 milliliters of blood per kilogram of body weight. A 70kg adult has about 5L of blood. It is responsible for the material exchange of all tissues and organs in the human body. If a person bleeds more than 30% of the total blood in a short period of time, he or she will die from excessive blood loss. Most deaths in traffic accidents, natural disasters, wars, etc. are caused by uncontrollable bleeding. Therefore, effective hemostasis plays a very important role in saving patients' lives. To achieve effective hemostasis, the use of hemostasis devices is indispensable.

At present, the hemostatic devices used clinically are generally tourniquets, i.e. gauze, which is wrapped around the wound to stop bleeding. For the position far from the joint on the limb, gauze can play a good compression hemostatic effect, while for the position close to the joint, such as the arm joint, since the joint is easy to bend, the tourniquet without elasticity such as gauze is directly used, which is very easy to be displaced or loosened due to the bending of the arm, and therefore, the hemostatic effect will be greatly affected. In addition, when the tourniquet in the prior art is wrapped on the wound layer by layer, the whole tourniquet is only attached together, so the air permeability is poor, and it is very easy to sweat, thereby causing infection.

The improved first aid hemostatic device according to the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

1 and 2 , an improved first aid hemostatic device according to an embodiment of the utility model includes an elastic cuff 10 , an elastic fixing belt 20 and a hemostatic assembly 30 .

The outer surface of the elastic sleeve 10 is provided with an escape hole 11 , and a strip-shaped positioning hole 12 is provided on both the front and rear sides of the escape hole 11 .

The elastic sleeve 10 is formed by connecting two ends of an elastic band, and has a certain elasticity, so it is suitable for patients with different arm sizes. The escape opening on the elastic sleeve 10 connects the inner and outer spaces of the elastic sleeve, and when the elastic sleeve 10 is put on the patient's arm, the escape hole 11 is opposite to the wound on the patient's arm.

The elastic fixing belt 20 is arranged on the right side of the elastic sleeve 10, and is used to wrap the elastic sleeve 10 on the patient's arm. The elastic fixing belt 20 is also made of elastic material, has elasticity, and is used to be bound to the patient's arm when the elastic sleeve 10 is sleeved on the patient's arm.

The hemostatic component 30 includes a connecting belt 31, a hemostatic patch 32 and a support seat 33; the connecting belt 31 is arranged on the outer surface of the elastic sleeve 10, the hemostatic patch 32 is arranged on the inner surface of the connecting belt 31, and is passed through the avoidance hole 11 to the inside of the elastic sleeve 10, and the support seat 33 is arranged on the outer surface of the connecting belt 31, and is used to prop up the elastic fixing belt 20 when the elastic fixing belt 20 is wrapped around the patient's arm, so that a breathable gap is formed between the elastic fixing belt 20 and the elastic sleeve 10.

The connecting belt 31 is arranged on the outer surface of the elastic sleeve 10 and covers the avoidance hole 11 on the elastic sleeve 10. The hemostatic patch 32 and the support seat 33 on the inner and outer surfaces of the connecting belt 31 are arranged relatively to each other up and down, wherein the hemostatic patch 32 is arranged relatively to the avoidance hole 11 and passes through the avoidance hole 11 to the inside of the elastic cuff, so as to stop the bleeding of the wound on the patient's arm, and the support seat 33 can prop up the fixing belt wrapped on the elastic sleeve 10, so that the part above the elastic sleeve 10 is away from the elastic sleeve 10. In this way, the fixing belt facilitates the formation of a certain gap between the elastic sleeves 10, that is, a breathable gap, to facilitate ventilation.

Specifically, when the present application is used, the elastic sleeve 10 is firstly sleeved on the joint of the patient's arm, and then the position of the wound is determined by two positioning holes, so that the hemostatic patch 32 is just opposite to the wound. Since the elastic sleeve 10 is elastic, it can be well adapted to the joint position. After the sleeve is set, the fixing belt is wound around the elastic sleeve 10. When winding, since the support seat 33 is arranged above the elastic sleeve 10, the fixing belt will be against the support seat 33. Under the support of the support seat 33, the fixing belt part above the elastic sleeve 10 will be lifted up and away from the sleeve body, thereby forming a certain gap between the two, which can be used for air circulation, thereby improving air permeability. At the same time, the fixing belt will generate pressure on the support seat 33, and the support seat 33 is opposite to the hemostatic patch 32 up and down, so the pressure will be transmitted to the hemostatic patch 32, thereby compressing the wound through the hemostatic patch 32 to play the role of compressing hemostasis and improving the hemostatic effect.

The improved first-aid hemostatic device provided by the utility model can be firmly wrapped around the joint position to stop bleeding at the joint position. At the same time, a ventilation space is reserved to facilitate ventilation and prevent infection.

Advantageously, in an embodiment of the present invention, a pocket 13 is provided on both the left and right sides of the elastic sleeve 10 , and the pocket 13 extends along the width direction of the elastic sleeve 10 for inserting a rod-shaped object.

On the one hand, the rod-shaped objects inserted into the pocket portions 13 on both sides of the elastic sleeve 10 can also play a role in supporting the elastic fixing belt 20, so that there is also a breathable gap between the elastic fixing belt 20 wrapped on the elastic sleeve 10 and the side of the elastic sleeve 10, thereby increasing the breathable gap and better improving the breathability; on the other hand, the rod-shaped objects inserted in the elastic sleeve 10 can also play a role in fixing the joints, that is, when a fracture patient uses the present application, since the rod-shaped objects are fixed on both sides of the joint, the joints can be prevented from bending. Therefore, the present application can also be suitable for fracture patients, and its applicability is better.

Advantageously, in one embodiment of the utility model, the hemostatic patch 32 includes a drug layer, a blood-absorbing layer and a connecting layer from bottom to top; the drug layer is provided with a hemostatic drug; the blood-absorbing layer is provided with blood-absorbing cotton; the connecting layer is connected to the connecting belt 31.

In this way, when stopping bleeding for a patient, the hemostatic drug in the drug layer can stop bleeding on the patient's wound and promote wound healing, while the blood-absorbing layer can absorb blood to prevent blood from flowing out and causing cross infection.

Advantageously, in another embodiment of the present invention, adhesive pieces 311 are provided on the inner surfaces of the left and right ends of the connecting belt 31 , and the adhesive pieces 311 are detachably adhered to the outer surface of the elastic sleeve 10 .

Preferably, the adhesive piece 311 is a double-sided adhesive with good adhesive effect, and can be removed. Therefore, for different patients, the hemostatic component 30 can be removed and replaced after use. Accordingly, the utility model can be recycled to reduce medical costs.

Advantageously, in some embodiments of the present invention, the support seat 33 includes a bottom plate 331 and a support protrusion 332; the bottom plate 331 is disposed on the outer surface of the connecting belt 31;

The base and the support protrusion 332 are both made of plastic material and have a certain hardness. The base is used to fix the support protrusion 332. Since the support protrusion 332 is bent and extended to the left and right sides, the elastic fixing belt 20 wrapped on the elastic sleeve 10 can be offset against the support protrusion 332. Under the support of the support protrusion 332, the part of the elastic fixing belt 20 wrapped above the elastic cuff will be lifted up by the support protrusion 332. In this way, a certain air permeability gap is formed between the elastic fixing belt 20 and the support protrusion 332, and the support protrusion 332 extends to the left and right sides. Therefore, the length of the support protrusion 332 can be increased, which is conducive to improving air permeability. In addition, when the support protrusion 332 supports the elastic fixing belt 20, the elastic fixing belt 20 will generate pressure on the support protrusion 332, thereby forcing the hemostatic patch 32 at the bottom of the connecting belt 31 to press the wound and improve the hemostatic effect.

Advantageously, in some embodiments of the present invention, a cotton pad 14 is provided on the inner surface of the elastic sleeve 10 .

The cotton pad 14 is made of flexible material. When wrapped around the patient's arm, it is in flexible contact with the skin, which provides better comfort.
