The invention relates to dispensers for supplying small portions of detergent or disinfectant solutions, in particular to dispensers for washing hands of medical personnel.

Known dispenser for liquid soap [1]. The dispenser includes a housing, a detergent container mounted on it and an elastic dispensing device. The metering device includes a check valve installed in the cavity of this device at the outlet of the tank, and is a hollow elastic element with a hole for supplying detergent.

The disadvantage of this dispenser is the inefficiency of the design when used as a means of hygiene for medical purposes.

A known container with a device for the portioned dispensing of liquid or pasty products, for example liquid soap [2]. The batch dispenser includes a cylindrical cap mounted on the neck of the container and a metering pump mounted coaxially. The outer diameter of the cylindrical cap is made smaller than the diameter of the container lid. The container in a vertical position with the lid down is fixed in the holder, and its cylindrical cap is placed between the front bearing wall of the holder and the pressure element of the swivel bracket of the metering pump.

The disadvantages of the device are due to the design of the possibility of arbitrary extrusion of part of the detergent from the elastic cylindrical cap and the inefficiency of using medical personnel for antiseptic processing of hands.

Known dispenser for batch delivery of pasty masses [3]. The dispenser includes a head equipped with a support unit located between the cover and the housing. The support unit contains a pivot pin and a groove. A piston is installed in the tubular body, which gradually moves in the direction of the exhaust nozzle during the exhaust process, with which the pressure head and the cover, which is actuated by the manipulator and extruded in the direction of the piston, and the cover covering the cross section of the outlet of the exhaust nozzle are aligned.

Disadvantages of the dispenser are the inefficiency of using liquid detergents and the inconvenience of using medical personnel for the hygienic treatment of hands.

Known dosing pump for toilet or cosmetic liquids [4]. The device comprises a cylindrical body with a suction channel rigidly attached to a cap screwed onto the bottle with an annular sealing protrusion. A double-acting piston is installed in the housing with the formation of a working chamber communicated through a non-return valve with a suction channel and disconnected from the internal channel in the rod in communication with the output channel in the head rigidly attached to the spring-loaded rod. The movable element of the check valve is made in the form of a cylinder, the diameter of which is less than the internal diameter of the spring. The lower end of the valve is installed with the possibility of interaction with the seat and is made in the form of a hemisphere, and the upper end with ribs protruding beyond the edges, placed with the formation of radial grooves directed perpendicular to the longitudinal axis of the movable element with the possibility of free entry into the grooves between the longitudinal ribs of the body. The rear wall of the piston is placed with the possibility of tight coverage of the annular protrusion in the lid of the bottle.

The disadvantages of the dosing pump are the low reliability of the dispenser and the discomfort when used for hygienic processing and disinfection of the hands of medical staff.

The limit stops of the swivel stop are made in the form of vertical pins of various heights, and the height of each pin corresponds to a predetermined volume of the working chamber of the piston dispenser and is configured to provide dispensing portions of detergent in a volume of 1.5-2.5 ml.

The invention is illustrated by drawings, which represent:

in FIG. 1 - general view of the device;

in FIG. 2 is a sectional view of the device;

in FIG. 3 - working chamber of the piston dispenser;

in FIG. 4 - piston metering rod;

in FIG. 5 - piston of the piston dispenser.

The device 1 comprises a housing 2 for a container 3 with detergent, a unit 37 with a pumping system 4 and a double-acting piston dispenser, including a piston 5 with upper 29 and lower 31 sealing cups with a seating seat 30 for valve 32 and an orifice 33; stock 6; spring 7; a check valve 8 in the working chamber 9, communicated through a check valve 8 with a suction channel 10 and disconnected from the internal channel 11 in the stem 6, in communication with the output channel 12 in the head 13 of the rod 6; manual drive in the form of a movably mounted lever 14 in the form of a rectangular bracket, the ends of which 15 are movably mounted on the axles 16 inside the bracket 17, made curved with the horizontal bar 18 positioned to interact with the axis 19 located in the plug 20 of the rod head 13 of the rod 6 in contact with the pusher 28; disk rotary stop 21 with travel stops in the form of pins 22, 23, 24, 25, made at the upper end of the working chamber 9; a tubular sprinkler 26 mounted in the output channel 12 of the head 13 of the rod 6 and placed in the protective cover 17 in the form of a bracket made on the front wall of the node 37 mounted on the supporting platform 27 in the housing 2; an information panel 38 on the front wall of the node 37 under the protective cover 17.

Device 1 operates as follows. Through mounting holes 34, 35, the housing 2 is installed on a vertical surface, for example on the wall of the operating room (not shown). A container 3 is placed in the housing 2, which is pre-filled with a liquid detergent or disinfectant, while the working chamber 9 is lowered into the neck of the container 3 (not shown in the drawing), and the suction channel 10 of the pumping system 4 is communicated with the bottom of the container 3 through the tube 36 and bring the device 1 into working position. By pressing the elbow of a person’s hand on the front plate 18 of the lever 14 through the axis 19 and the pusher 28 of the rod 6 they move the piston 5 in the working chamber 9 vertically downward, compress the spring 7 and actuate the metering pump system 4. The valve 32 in the seat 30 tightly closes the passage the hole 33 in the piston 5. When releasing the bar 18 of the lever 14, the spring 7 is unclenched, pushes the piston 5 up and due to the tight pressing of the upper 29 and lower 31 sealing lips of the piston 5 to the walls of the working chamber 9 create a vacuum in it, and liquid from the tank 3 through the tube 36 th cut the suction channel 10 enters the working chamber 9. When the lever 14 is pressed again, the check valve 8 closes the suction channel 10, and a portion of the liquid from the working chamber 9 with the piston 5 through the passage 33 with the valve 32 through the internal channel 11 in the rod 6 is forced into the outlet the channel 12 of the head 13 and then through the sprinkler 26 is directed to the hands of a person (not shown). At the same time, the bracket 17, made in the form of a cover covering the sprayer 26, reliably protects it and the associated head 13 of the piston dispenser from possible damage when pressing the strap 18 of the lever 14 or accidental mechanical impact on the sprayer 26 in the inoperative mode of the device 1.

The adjustment of the portion of the liquid is carried out by turning around the axis of the housing of the chamber 9 with a disk rotary stop 21 of the pumping system 4 in the hole with the locking grooves in the base of the node 37 (not shown). For this, the piston metering chamber 9 is displaced vertically upward with respect to the base of the assembly 37 and compresses the spring 7 until it rotates out of the groove of the lower protrusion of the stroke limiters 21, rotate it, then install the corresponding stroke limiter pin 22, or 23, or 24, or 25 under the lower the platform of the protruding part of the head 13. As a result

- 2 017060 when the piston 5 moves downward under the influence of the lever 14 on the pusher 28 through the axis 19 in the plug 20, the rod 6 moves only to the stop of the lower platform of the protruding part of the head 13 into the corresponding pin of the travel stop of the rotary stop 21, restricting the vertical movement of the rod 6 in according to the height of the limit pin.
