Description

A kind of venous compression hemostat

technical field

The invention belongs to the field of medical equipment, and in particular relates to a venous compression hemostat.

Background technique

At present, the clinically used venous compression hemostatic devices mainly include medical cotton swabs, medical cotton balls, medical gauze, intravenous infusion stickers, etc. Although the above compression hemostatic devices can achieve a certain hemostatic effect, they still have the following limitations and disadvantages: manual use The hand is pressed for a long time, the pressing area is small, the pressing force is uneven and the pressing force cannot be effectively controlled, and the operation is inconvenient.

After the venipuncture needle is removed, improper selection of pressing methods and pressing instruments may easily cause complications such as bleeding at the puncture point and subcutaneous congestion, which will increase the pain of the patient and affect the success rate of re-puncture. The bleeding time of normal people is 3 minutes, and the coagulation time is 3-5 minutes. For patients with heparin and delayed coagulation function, the compression time should be extended appropriately, preferably 15 minutes. Due to the cotton swab itself, the traditional pressing method with cotton swabs makes the pressing area smaller, the force is uneven, the pressing process is not stable, and the cotton swab shifts, causing skin bleeding, subcutaneous bleeding and other adverse events. To achieve effective hemostasis after venous blood collection, the pressure should be uniform and moderate. Too little force will not achieve the effect of pressing to stop bleeding, and too much force will cause pain to the patient.

The applicant has previously developed a push hemostat (CN204655029). The push hemostat includes a hollow cylinder. An adhesive strip with one end connected to the cylinder is provided on the lower bottom of the cylinder. The bottom of the cylinder is filled with cotton balls. The inner surface of the body is provided with a groove, the upper end of the cylinder is provided with a column cap that can be embedded in the column body, and the column cap is provided with a limit rod and a pressure rod. The protrusion in the groove, one end of the pressure rod is fixed on the column cap, and the other end is connected with the cotton ball. Although this hemostat can realize automatic and continuous pressing to stop bleeding, its structure is relatively complicated. It is not convenient enough during production and use.
