Problems solved by technology

[0002] At present, low-cost gauze is generally used as a hemostatic emergency bandage in medical treatment. Although this bandage can meet the dressing requirements for wounds, objectively there are the following deficiencies: 1. Because the gauze has poor liquid absorption and anti-leakage effect, it is prone to blood stains and liquid medicine penetration, which is not only detrimental to the view, but also prone to pollution, such as dirt and clothing; Therefore, medical staff usually wrap several layers in a way of preferring more than less, resulting in a large amount of material consumption, that is, unnecessary waste, and an increase in the treatment cost borne by patients; Adhesion occurs, so that although the wound is healing but still in a fragile state, it will suffer secondary damage (tearing) when the bandage is withdrawn; fourth, because the gauze itself does not have the functions of antibacterial, healing and pain relief on the wound, it can only play a role To fix the application on the wound and isolate it from the outside world

Embodiment 1

[0020] preparation figure 1 The steps of the hemostatic bandage with the structure shown are as follows:

[0021] A) To prepare the wound treatment pad, the anti-adhesion film 22 with a grammage of 15g / ㎡ is heated and compounded by a thermal compounding machine, and compounded to a non-woven alginate fiber with a grammage of 160g at a heating compounding temperature of 110°C The cloth 21 faces one side of the patient's wound in the use state, and the polyurethane breathable film 23 with a grammage of 2 g / ㎡ is heated and composited to the other side of the alginate fiber non-woven fabric 21 at a temperature of 105 ° C. side, and then cut into a cube with a side length of 10 cm by a cutting machine to obtain a wound treatment pad 2. The anti-adhesion film described in this step is preferably used by the British Smith & Nephew company in the Chinese market before this application is proposed. The grade is CM-type mesh isolation film or the mesh isolation film sold in China ...

Embodiment 2

[0024] Only change the gram weight of the anti-adhesion film 22 in step A) to 20g / ㎡, change the heating composite temperature of the anti-adhesion film 22 and the alginate fiber non-woven fabric 21 to 115°C, and the alginate fiber non-woven fabric 21 The gram weight was changed to 200g / ㎡, and the alginate fiber non-woven fabric 21 was produced by Changshu Mintai Medical Dressing Co., Ltd., Jiangsu Province, China and sold on the market before this application was filed. The brand is MT-Ⅱ-A biological fiber For non-woven fabrics, change the heating composite temperature of the polyurethane breathable film 23 and the alginate fiber non-woven fabric 21 to 115°C, change the weight of the polyurethane breathable film 23 to 3g / ㎡, and change the side length of the wound treatment pad 2 after cutting Change it to 15cm; change the ironing temperature in step B) to 125°C, change the transition distance to 10cm, change the length of the bandage body 1 to 360cm, and change the width to 1...

Embodiment 3

[0026] Only change the grammage of the anti-adhesion film 22 in step A) to 17g / ㎡, change the heating composite temperature of the anti-adhesion film 22 and the alginic acid fiber non-woven fabric 21 to 120°C, and the alginic acid fiber non-woven fabric 21 Change the gram weight to 120g / ㎡, and change the heating composite temperature of the polyurethane breathable film 23 and the alginate fiber non-woven fabric 21 to 110°C, and change the gram weight of the polyurethane breathable film 23 to 5g / ㎡. Change the side length of pad 2 to 5cm; change the ironing temperature in step B) to 125°C, change the transition distance to 8cm, change the length of bandage body 1 to 305cm, and change the width to 5cm , and the rest are the same as those described in Example 1 .

Abstract

The invention provides a hemostasis bandaid and a preparation method of the hemostasis bandaid, and belongs to the field of surgical dressing. The hemostasis bandaid comprises a bandaid body and a wound treating pad. The wound treating pad is combined on one side surface of one end of the length direction of the bandaid body, and a transition distance is reserved between the wound treating pad and the end portion of the end with the wound treating pad. The hemostasis bandaid is characterized in that the hemostasis bandaid is formed by alginic acid fiber non-woven fabrics, an anti-adhesion thin film and a polyurethane breathable thin film, the anti-adhesion thin film is combined on one side, facing the wound of a patient, of the alginic acid fiber non-woven fabrics in a using state. The polyurethane breathable thin film is combined on the side, facing the bandaid body, of the alginic acid fiber non-woven fabrics, and the bandaid body is medical absorbent gauze. The hemostasis bandaid not only has good effects of liquid imbibition and seepage resistance, but also has excellent effects of hemostasis, antibiosis, healing promotion and pain relieving to the wound, can avoid blindness, avoid waste and reduce treatment cost of the patient, cannot cause adhesion to the wound, and can meet requirements of expanding production of industrialization.

technical field [0001] The invention belongs to the technical field of medical dressings, in particular to a hemostatic first aid bandage, and also relates to a preparation method of the hemostatic first aid bandage. Background technique [0002] At present, low-cost gauze is generally used as a hemostatic first aid bandage in medical treatment. Although this bandage can meet the dressing requirements for wounds, objectively there are the following deficiencies: First, because the gauze has poor liquid absorption and anti-leakage effect, it is easy to appear. Blood stains and liquid seepage phenomena are not only detrimental to vision, but also prone to pollution, such as dirt and clothing; second, as mentioned above, because of the poor effect of absorbing liquid and preventing leakage of gauze, medical staff usually prefer more than less when dealing with them. Wrap several layers by way of wrapping, resulting in a large amount of material consumption, that is, unnecessary...
