Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a venous puncture compression hemostatic dressing. Background Art

[0002] Intravenous infusion therapy is a common treatment method in hospitals. After the needle is removed, effective pressing is required to protect the blood vessels. The pressing methods currently used in clinical practice are manual cotton swab pressing or retaining infusion patch pressing. Although there are many pressing methods, if the pressing method is improper, the pressing pressure is unstable, the pressing position and pressing time are incorrect, it can cause skin bleeding, ecchymosis, subcutaneous hematoma, etc. at the puncture point, and even cause distal limb blood circulation disorders, with an incidence rate of up to 72.5%. In addition, it will cause difficulty in re-puncture, make patients fearful and cause dissatisfaction with nursing work. In addition, due to the differences in the thickness of the patient's skin fat and the nurse's personal operating habits, the skin needle hole and the blood vessel needle hole are often not at the same point, and the longest horizontal distance is about 2.0 cm.

[0003] Especially for critically ill patients, patients with hemiplegia, patients in anesthesia coma and patients without clinical care, they cannot independently perform hemostasis when compression hemostasis is needed. In addition, for elderly patients and infants, different degrees of bleeding, ecchymosis, subcutaneous hematoma and venous occlusion may occur due to the different compression strengths required. Therefore, during the operation, medical staff cannot independently adjust and maintain the predetermined appropriate compression strength according to needs, and cannot simultaneously perform compression hemostasis on the puncture points on the skin and the puncture points on the blood vessels.

[0004] The Chinese patent with announcement number CN209678598U discloses a self-expanding intravenous compression hemostatic patch with built-in bursting beads, which includes adhesive tape, polyvinyl alcohol sponge, bursting beads and sterile water. The bursting beads and sterile water are arranged, which is conducive to the bursting beads with sterile water arranged in the polyvinyl alcohol sponge. After being attached to the puncture point, the bursting beads are quickly crushed, the water is released, the sponge expands, and pressure is quickly generated to play the role of compression hemostasis. Although it solves the problem that ordinary dressings in the prior art need to be pressed for a long time, and the puncture point often continues to ooze blood or local bleeding and bruising after pressing, and even causes infection, it still has the problem that the predetermined compression force cannot be freely adjusted according to demand.

[0005] In view of this, the inventor conducted in-depth research on this demand, and thus the present case was produced. Utility Model Content

The pressure regulating belt is fixed to the patient's body through the adhesive block, which is used to maintain the rubber plug column and adjust the compression force, effectively avoiding the position deviation of the pressing position during the process of the nurse handing over the pressing to the patient after the needle is removed and the position deviation of the patient during the pressing process.

[0007] Preferably, sterile hemostatic cotton is provided on the lower surface of the sterile dressing pad at a position corresponding to the rubber stopper column.

[0008] Preferably, an adhesive layer is provided on the lower surface of the sterile dressing pad and in the area not covered by the sterile hemostatic cotton.

The limiting groove can accurately locate and cover the two puncture points on the patient's skin and blood vessels, and the stopper column is placed on the limiting groove to compress and stop bleeding at the two puncture points on the patient's skin and blood vessels.

[0011] Preferably, the sterile hemostatic cotton is cylindrical, and its diameter is 2.8-3.5 cm, for example: 3.0 cm.

[0012] Preferably, the stopper column is a cylinder, and the diameter of the stopper column is 1.8-2.2 cm, and the height of the stopper column is 0.8-1.2 cm.
