Detailed description of the invention

For summary of the invention of the present utility model, feature and effect can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows, refer to Fig. 1-Fig. 6.

As Fig. 1, shown in Fig. 2: with soft silica gel make and be close to the breastshield 1 of the bell mouth shape in breast of mothers, be tightly connected out latex dust 2, go out one end of the other end connecting tee valve 3 of latex dust 2, the other end of three-way valve 3 is connected to connection tube 4, connection tube 4 connects syringe 5, syringe 5 is built with piston and piston rod 6, described three-way valve 3 is connected with feeding bottle 8 by silica gel tube 7, silica gel plate 8-1 is placed with between the bottle cap of feeding bottle 8 and bottleneck, its diameter of silica gel plate 8-1 central openings is identical with silica gel tube 7, silica gel tube 7 inserts in feeding bottle 8 by the aperture of silica gel plate 8-1 central authorities, shown in Fig. 3-Fig. 6: described three-way valve 3 comprises valve body 3-1, spool 3-2, upper three the hole pipes of valve body 3-1 and A hole 3-4, B hole 3-5 and C hole 3-6,3-4 place, A hole is fixed with the stifled 3-10 of plug, spool 3-2 has long through-hole and short-bore F hole 3-9 that two two ends are D hole 3-7 and E hole 3-8, long through-hole and short-bore mutually perpendicular and communicate, spool 3-2 rotates in valve body 3-1 at the drive bottom spool 3-2 of knob 3-3, and the inwall of described valve body 3-1 and the contact surface of spool 3-2 cylindrical all have employed frosted process, described breastshield 1, go out latex dust 2, three-way valve 3, connection tube 4, syringe 5 and corresponding being interconnected of feeding bottle 8 and be and removably connect so that clean, described syringe 5 can select the medical needle tubing of 20ml or 50ml according to negative pressure difference needed for the individual variation of different people, in described three-way valve 3, the left side of valve body 3-1 is connected with syringe 5 by connection tube 4, and the right of valve body 3-1 is passed through latex dust 2 and is connected with breastshield 1.

During operation, first, as shown in Figure 5: turning knob 3-3 makes the B hole 3-5 on the D hole 3-7 of long through-hole one end on spool 3-2 and valve body 3-1; And on spool 3-2 the long through-hole other end E hole 3-8 align respectively with the C hole 3-6 on valve body 3-1, again breastshield 1 is close in breast of mothers, because the B hole 3-5 on valve body 3-1 is connected with syringe 5 by connection tube 4, when pulling piston and piston rod 6 sucks, form negative pressure in connection tube 4, the milk be sucked out enters in syringe 5; Described syringe 5 and piston and piston rod 6 are power resources of breast pump, its syringe 5 is again interim milk storage device, when after first time sucking-off milk, as shown in Figure 6: counter-clockwise turning knob 3-3 makes the F hole 3-9 on spool 3-2 and D hole 3-7 align with the B hole 3-5 on valve body 3-1 and A hole 3-4 respectively, then, promote piston and piston rod 6, in milk press-in feeding bottle 8; The spool 3-2 that linked by knob 3-3 again rotates clockwise, spool 3-2 returns state as shown in Figure 5, now, start the operation carrying out sucking for the second time, then, knob 3-3 links, and spool 3-2 is counter-clockwise again to rotate, breast milk is pushed in feeding bottle 8 from syringe 5, so repeatedly carry out, after milk sucks, take off feeding bottle 8 and with plug stifled 3-10, the A hole 3-4 on valve body 3-1 blocked.

Its advantage is: suction is adjustable, is conducive to treatment and the prevention of galactocele, prevention puerperal mastitis, and help the depression of correcting nipple, structure is simple, and safety and sanitation, are convenient to cleaning and disinfection, and cost is low.

Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from this utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that this utility model claims determine.
