FLUID APPLICATION DEVICE AND METHOD Russian patent published in 2014 - IPC A61M35/00 A45D34/00 B65D83/00 

FIELD: medicine.

SUBSTANCE: liquid applicator comprises a handle, a base and an applicator pad. The handle has proximal and distal ends and comprises a receiver and an elastic cap. The receiver is configured to enclose a package comprising liquid, and to facilitate the liquid removal from the package. The elastic cap is configured to close the package tightly and to deflect under an external pressure, providing thereby applying the external pressure to the package if the latter arranged inside the receiver, to compress the package and to ensure bleeding. The base projects in the radial direction to the outside at a non-zero angle from the distal end of the handle. The base is configured to guide the liquid flow and comprises a distal hole and an outer wall projecting in a transverse direction to the outside from the base and arranged circumferentially about the distal hole. The pad is attached to the base hydraulically connected to an inner portion of the receiver. A portion of the pad is inserted inside the distal hole, while another portion of the pad is wound about the outer wall to delimit the portion of the pad inside the distal hole of the base. According to the second version, the liquid applicator comprises at least one ventilation element configured to supply air into the receiver and discharge it from there. A liquid application system comprises the liquid package, and the aforesaid applicator. The package comprises the first and second opposite sides of the package forming a hermetically sealed liquid space in between, and a fragile section. The fragile section is configured to be ruptured under the force applied to the package to remove the liquid from the package. The system possesses the property of collapse enabling the first side of the package to be transformed from an arch position into a dish position, when the package is compressed to collapse the previously hermetically sealed space almost completely. The method for applying the liquid on the surface involves applying pressure to the elastic outer surface of the handle on the proximal end of the applicator and pressing the liquid-filled package inside the handle, thereby compressing the elastic portion of the package and rupturing the fragile section of the package for the package bleeding; enabling the liquid flowing through the handle through the distal hole at the base on the distal end of the applicator to the applicator pad attached to the base; and contacting the applicator pad to the surface for the liquid transfer from the applicator pad to the surface.

EFFECT: invention provides time- and quantity-accurate delivery of the required preparation.
