Milking pump.

Abstract

A milk suction device consisting of a funnel and a piston pump connected thereto which can be operated easily as a hand-operated pump or as a motor driven pump. A hollow piston rod is constructed as an outwardly guided aeration duct and has a return valve as its opening located in the suction space of a cylinder of the pump, which return valve is closed during the suction stroke of the piston pump and is constructed as an aeration valve. A ventilation valve is arranged in a front face of the pump cylinder opposite the piston rod and in order to connect a motor driven pump, it is only necessary to slide its tube onto the free end of the piston rod.

ULKOKIA DESCRIPTIVA

The invention relates to a device for sucking breast milk with an otabudo that attaches to the chest. A funnel is then placed through a pump that produces a non-contact pressure in the funnel. Together with the relatively simple rubber balloon pumps, they also use diaphragm pumps as well as hand operated plungers. They are also already familiar with manual cloning suction devices, which can also be operated with a motor-driven pump. For this purpose, on the other hand it is necessary to use either adapters or change whole pieces. As a result of handling something uncomfortable, * little practicality is done in practice,

The invention is based on a sucoop deviceeamaternal milk that consists of a funnel and a pump do. éjabe »connected to it, with piston rod as well as drain and vent valve, and has the mission logr ^ y *. A device which, on the one hand, produces a uniform pressure equal to that possible, and, on the other hand, can be connected without great difficulty to a pump which, if desired, can be operated by motor.

According to the invention, the piston rod of the hollow piston is formed as an air discharge channel directed to the outside, and has at its outlet a check valve shaped as a discharge valve, closed at the suction stroke. Thanks to the arrangement of two valves, it is possible, in contrast to other devices of this type, to keep the negative pressure constant, to avoid the unpleasant rises and falls of the negative pressure for the user of the device. * In an especially simple way it can be connected a motor-driven pump · In fact,

device, on the piston rod of the hollow piston that comes out to the outside »Preferably, the vent valve is disposed on the front surface of the oil cylinder of the pump directed to the plunger rod, so that the entire space is freely available * * cylinder for piston stroke ·

According to another characteristic of the invention, the stem of the piston is connected articulately with one of the ends of a two-armed lever, arranged.andor; oscillating mode, whose other end is shaped as a handle. With this, in the process of suggestion, contrary to •

as suoede in other pumps, the funnel is pressed against the chest and not removed from it, so that a tight support is provided. · Conveniently, the end "rigid" to the outside of the The piston rod is shaped like a removable capsule for the flexible tube. It sucks a motor pump and protrudes above the point of articulation of the lever. This way, the flexible tube can be connected without any difficulties. a motor pump, and above all without obstructing the operating palonea ·> According to another characteristic of the invention, the part of the lever formed as a handle is shaped at its free end as a support and is so long that, while in one position,it is located approximately in the same plane as the bottom of a milk collecting tank located in the suction device · With this, the device

of suction can be placed without lying down. Preferably an overpressure valve, especially adjustable, is arranged in the funnel. This prevents the negative pressure created by the venting and emptying valve arrangement from rising too high and damaging the user.

The drawing shows an exemplary embodiment of the invention, namely a cross section of a milk suction device with a leetie collection tank.

• e • · ·

The funnel 1 applicable to a breast, not shown '·, is connected to a piston pump 2, and both are screwed to the milk collection tank 3. Below the andbemand The plunger rod 2 is provided with a support arm 4 which protrudes backwards, in which a lever with two arms 5 is supported so that it can be swiveled at 6. This lever is hingedly articulated at its upper end, at 7 °. " with. ql »plunger rod 3, which protrudes rearwardly of the cylinder 2 of the pump 2. The plunger rod 3 is hollow and has an air discharge channel 10 qbrConnect the suction space 11 with the outside air.

At the end of the rod of the piston 8 that opens into the suction space 11 a check valve 12 for the air flow is arranged, valve which closes at the suction stroke in the rotation of the arrow 13 · On the front face 14 of the cylinder 9 directed towards the piston 8 is provided a ventilation valve 15 also formed as a check valve, which is connected through a channel 16 to the milk collecting tank 3 and »thereby, to the funnel 1.

The rear end of book 17 of the piston rod

Four.

it is stretched and shaped as a plug-in capsule for the flexible tube of a motor pump not shown · The lower part 18 of the lever 5 serves as a handle and its lower end 19 is formed as a support. When the lever 5, in the example shown, is in one of its extreme positions, the support 19 is approximately in the same plane as the bottom 20 of the milk collecting tank 3, with what the lever 5 serves as a device of support for the pump 2 that protrudes considerably above the base surface of the tank · · · · milk sensor 3. ·····

In the funnel 1, a vent opening 21 is provided, which can be covered by hand and which serves to regulate negative pressure. To safely prevent the chest from being injured by too strong a negative pressure, another deflection valve is provided in the funnel, whose spring plate can be adjusted from the. ·to way that it is possible to regulate the maximum pressure. In case . · · Negative pressure too strong, can then *one Will you add the air in the outside through this valve?

For the suction of the leohe, the funnel 1 is placed in the chest, the opening 21 a closes with a finger and moves to each other and the handle 18 of the lever 5 · When the eaa 13 of the lever 5 ee press in the direction of the ball 23, that is, center the ball, the piston rod 8 moves in the direction of the arrow 13 and pulls the piston 24. The drain valve 12 is then opened and the valve is opened of ventilation 15, so that a negative pressure is produced in the funnel. The milk is thus sucked, which flows into the reservoir 13. If the handle 18 moves in

In the opposite direction, the vent valve 15 is then closed and the drain valve 12 is opened, so that the plunger 24 has moved it to its previous position. In tone, the funnel 1 and the collector reservoir of Leebe 3 are closed outside the chest and the valve 15, so that the negative pressure is maintained as long as it does not change releasing the opening 21.

When working with a motorized pump, it is only necessary to introduce a non-represented phlebitic tube of this pump at the end 17 d * lV piston rod 8. In the suction process, open both valves 12 and 15, so that other * ·· measures are not necessary, as for example the arrangement of an adapted * or similar. To remove the apparatus, the handle 18 is placed in one of the end positions and then serves as a support to support the weight of the plunger pump 2 that exceeds it. ·. · '·

The materials, foznna. and tamper of the elements are susceptible of variation provided that it does not imply a belief in the essentiality of the invention. · · · ·

The terms in which this report was drafted should always be taken in a broad non-restrictive sense.
