Description

Convenient and easy-to-pressurize wound surface hemostatic dressing

Technical Field

The utility model relates to a medical hemostatic material technical field especially relates to a convenient easy pressure boost surface of a wound hemostasis dressing.

Background

At present, in clinic, intravenous injection, intravenous blood sampling, intramuscular injection, joint puncture, spinal puncture and various biopsy punctures are adopted, the adopted hemostatic dressing is usually gauze, cotton balls or cotton swabs, and most patients do not have professional hemostatic common knowledge or attach no attention to the hemostatic dressing, and often do not implement hemostasis according to standard actions, so that many complications or adverse reactions are caused, such as: red swelling, blood stasis, pseudophlebanoma, etc.

The way patients self-stanch blood often has the following misdistricts and irregularities:

(1) the pressing position is inaccurate: only the bleeding surface opening, namely the puncture needle eye, is pressed, the puncture angle is about 30 degrees, the puncture surface opening and the puncture inner opening are not in the same vertical direction, and if the bleeding outer opening, the bleeding inner opening and three points of the last section of blood vessel are not pressed simultaneously after the needle is pulled out, only the bleeding outer opening is pressed, the bleeding of the surface opening and the bleeding inner opening are easy to occur, so that the pseudophlebangioma is formed, and the like.

(2) The pressing action is not standardized: immediately after the blood is collected and the needle is pulled out, because a blood coagulation mechanism exists in a process, a patient usually carries out edge-pressing and kneading or continuously and repeatedly carries out pressing and loosening actions, so that a primarily formed blood clot can be damaged, and bleeding is accelerated.

(3) Too short pressing time: the blood drawing routine needs to be pressed for 3-5 minutes, when the special part and the puncture needle hole are large, the pressing needs to be carried out for about 15 minutes, the corresponding time needs to be prolonged after the blood drawing of a patient with poor blood coagulation mechanism or old patients, and the patient often has too short pressing time due to no corresponding medical knowledge and has the phenomenon of blood stasis or hematoma;

in order to avoid the problems, most of the wound dressing pastes are clinically used for assisting patients in hemostasis to a certain extent, but most of the wound dressing pastes in the prior art are strip-shaped flexible wound dressings which can be pressed forcibly only by bare hands, so that labor and time are wasted, bleeding points are not easy to be found accurately when the wound dressings are pressed by bare hands, and displacement is easy to occur; on the other hand, the strip wound dressing is pasted at two ends, the dressing is often warped or separated due to the movement of joints or skin in the using process, and the effect of compression hemostasis cannot be achieved.
