Description

Positive pressure patch

Technical Field

The utility model belongs to the field of medical instruments, and particularly relates to a positive pressure patch.

Background

In the postoperative recovery of various minimally invasive operations, in order to prevent wound bleeding, doctors often adopt a hemostat to press and stop bleeding on a wound part, more commonly a tourniquet, but the hemostasis mode has a larger pressing range, and can prevent normal blood circulation of peripheral blood vessels and tissues except the wound part. In addition, there is a compression hemostasis mode which is self-compression hemostasis, that is, a patient or a nursing staff presses a wound by hand to prevent bleeding, and the compression hemostasis mode is very inconvenient.

Firstly, the force cannot be controlled, and because the thickness of the adipose tissues of each patient is different, the required pressing force is different naturally, and secondary bleeding is very easy to be caused by improper pressing force in the pressing process. Secondly, the pressing position cannot be fixed, especially for old people and infants, and the external nursing staff is required to press the pressing position because the pressing position cannot be pressed by the pressing position, however, the body of the patient cannot be rotated by the postoperative because of pain, and the external nursing staff cannot move along with the body movement of the patient in the first time.

The utility model patent CN210472392U discloses a wound plaster which comprises base cloth and an air bag; the base cloth is provided with an inner surface and an outer surface, the inner surface is opposite to the outer surface, at least part of the area of the inner surface is an adhesive surface for attaching to skin, the air bag is internally provided with preset air pressure, the air bag is arranged on the base cloth, and the air bag is used for covering a wound through the base cloth. The utility model can replace the fixation, avoid cross infection, adopt the gasbag of adjustable atmospheric pressure to press the wound, be applicable to the patient of different age groups, have alleviateed the oppression and the injury to the tissue except wound. The gasbag adopts the air pressure of predetermineeing in this patent, can be according to the different air pressures of drawing selection of different pressure demands's wound plaster of predetermineeing, but in actual operation if the insufficient wound plaster of corresponding air pressure probably appears and does not prepare, thereby can't select the wound plaster of suitable air pressure to use and bring discomfort or pressure inadequately need the manual work to press to reach hemostatic effect for the patient. In addition, the patent also mentions that the pressure of the air bag can be regulated through a one-way valve on the air bag, and the operation of the air bag needs to be provided with a pressurizing device to increase the operation steps, so that the operation efficiency is reduced.
