Abstract

The utility model discloses a negative pressure breast pump by hand which is composed of a syringe (8), a container (9), an observation case (3), a valve gate (2) and a milk cup. The observation case is provided with four valve gates which are respectively connected with the four milk cups, and the observation case is made up by apparent material. The advantages of the utility model are that the milking operation can be proceeded without power supply, and the quality and quantity of the milk can be known directly because of the arranged observation case and the four valve gates, the valve gate corresponding to the breast which can not make milk is closed in time, and the health of the breast of the cattle is guaranteed.

Description

Negative pressure breast pump by hand

This utility model relates to a kind of hand negative pressure breast pump.

At present, the milking machine that uses of people is electronic or motor-driven milking machine and can not uses in the occasion that does not have power supply and power; Another shortcoming of this class milking machine is when milking for milch cow, and that can not observe cow teats goes out the milk situation, and certain nipple of cattle has not gone out milk sometimes, and milking machine is still ceaselessly being inhaled, thereby damages cow breast, causes milk yield to descend.

The purpose of this utility model is that a kind of hand negative pressure breast pump will be provided, and it has one and produces means for applying negative by manpower and have one and can observe nipple go out the to suckle observation box of situation.

Fig. 1 is the structure principle chart of hand negative pressure breast pump.Container among the figure (9) can be a milk churn.Inner chamber with sealing is provided with a depression generator (being pump (8) among Fig. 1) covering of container (9), and pipe joint (10) and Pressure gauge (13) all communicate with container intracavity; Observation box (3) is a box body, both can be enclosed, also can be that wherein one side can be opened, as shown in Figure 1, the observation box of openable has a sealing gasket (4), be equipped with cover plate (5) above and cover plate combined tightly with observing box body, guarantee the sealing of observation box by fastening bolt (7) and spring leaf (6); Observation box can be a whole clearing, can be partially transparent also, so as to observe each cow teats go out the milk situation.

Observation box (3) is provided with four valves (2), and each valve all is communicated with a milk tube (1), and the other end of milk tube (1) connects cupping glass; Cupping glass is enclosed within on the cow teats; The inner chamber of observation box communicates by the inner chamber of milk tube (11) with container (9).

During use, earlier four cupping glasss are enclosed within respectively on four nipples, press pump (8) then, make and produce negative pressure in the container (9), and negative pressure is reached cow teats through milk tube (11), observation box (3), milk tube (1), and with the Lac Bovis seu Bubali sucking-off, Lac Bovis seu Bubali flows into observation box (3) respectively along four milk tubes, and enters container (9) thus.Between operational period, operator are by observing observation box, and that can know each nipple goes out the milk situation, if the milk in a certain nipple blots, no longer goes out milk, and operator can prevent that nipple from damaging with corresponding with it valve closing on the observation box.

The power source that the utility model has the advantages that breast pump is manpower, does not have the problem that expends the energy, and all can be used to inhale newborn operation in any one place; Owing to adopted observation box in the breast pump, what make that operating personnel can observe each nipple easily goes out the milk situation, can in time close and does not go out to suckle the corresponding valve of nipple. Guaranteed the normal condition in cow's milk room; In addition, by observation box, operating personnel can recognize the milk matter of cow and go out the milk amount, conclude that in time milk normal or cow is ill, or the nerve stimulation problem, so that in time for cow treatment or timely massaging breasts, with the increase output of milk.
