Description

 The invention relates to a breast cup for the female breast with one that collects lactated milk

Collection container connected to the breast cup.

It may be important to get breast milk without breastfeeding baby from the female breast. The reasons for not having a child suck directly on the mother's breast can be very different. Examples for this are:

Premature birth or illness of the child

 the amount of milk in the mother should be increased, in the case of sores or injured moms,

 - in diseases of the mother, you do not

 allow the child to breastfeed and still the

Breast must be emptied.

Also, for purely practical reasons, it may be desirable to enable a person other than the mother to feed the infant with breast milk.

For breast milk secretion, three effects are known that cause breast milk to come out of the breast:

A) In the chest itself, an internal pressure is caused by the oxytocin effect mediated through the bloodstream. The oxytocin causes the immediate contraction of the small muscles that make up the milk-producing cells

Envelop (alveoli). This effect is also called

Milchspendereflex called. He is strongest

caused and positively influenced by stimulation of the nipple with simultaneous relaxation, warmth, freedom from anxiety and pain and gentle massages at all appropriate points of the maternal body. An important difference Among the effects mentioned below is that the milk flows only because the milk bubbles are internally compressed. Without the oxytocin, there would be virtually no milk secretion, even with a heavy breast and heavy sucking.

B) Another effect that causes milk to come out of the breast is a pronounced mechanical pressure on the female breast, hereafter referred to as milking pressure, because the way it resembles the processes of hand milking, such as it is known from animal breeding. On the one hand (variant-Bl), this pressure can be generated quite naturally by the child by exerting on the areola and the nipple a milking chewing movement with the help of the palate, tongue, cheeks and jaw strips. On the other hand, a very similar pressure as by the child

(Variant Bl), by milking finger movements of the mother or a helper (variant-B2) on the areola

be executed. This rhythmic executed milking pressure in connection with an effective milk donor reflex (effect A) alone is sufficient to produce full breasts in a short time

To empty time. A major disadvantage of the variant-B2 so far is that the collection of milk is problematic. Because the up to 20 Milchausführungsgänge spread over the entire Mamillenspit ze and the milk can splash in all directions meter-wide.

C) The third known effect which causes milk secretion is the infant's vacuum or suction applied to the breast or a fitted breast pump. The disadvantage of using pumps is that they exert a strong strain on the nipples. The negative pressure through an electric breast pump is significantly higher than by an infant and is adjustable up to 300 mmHg. However, an infant produces only one Negative pressure of 55 to 150 mmHg. In the case of solid nipples, it is very difficult or even impossible to obtain milk with a pump.

These three effects A, B and C can be different

work together, so that it comes to a milk secretion.

In case a baby is breastfed directly on the breast, all three effects A, B and C are combined. This means that a healthy baby, when effect A works, causes effect Bl through its sucking effect C and simultaneously with the palate, tongue, etc. as described above.

For example, US Pat. No. 7,607,965 Bl discloses a type

Suction extension for nursing mothers who do not want to expose their breasts in public. The suction extension is applied to the bra of the mother and the end of this extension out to the mouth of the infant, which sucks over the milk from the breast. The US Pat. No. 7,607,965 B1 merely represents a connecting piece between the breast of the mother and the baby to be breastfeeding. Only the effects A and C are effective. Another possibility of milk secretion is this

 Squeezing breast milk or emptying the breast by hand. Only the effects A and Variant B2 are used. In 2003, the inventor herself published a video of her (video tutorial from the Still Practice, E. Kurth, IBCLC: "Breastfeeding - Emptying the Breastmilk")

Hand Breast "2003) describes a method of manual breastmilk production that requires only a collecting vessel as an aid, allowing the woman to apply a rhythmic, precisely metered, milking mechanical pressure to the areola region in the

Interaction with oxytocin is perfectly sufficient to thoroughly empty a full breast. By the way, this causes Pressure a stimulation of the nerves, which, as described above, is necessary for the ejection of the milk, wherein the exercise of the milking mechanical pressure in addition to the effect of the oxytocin essential for the promotion of the

Milk delivery is. This is not one

Massage, but a milking process.

However, the collection of valuable breast milk is not so easy.

Another way of milk secretion is the

Use of milk pumps. These, when effect A works, only use the effect C by passing through the

Pumping effect generated negative pressure to effect the

Use milk secretion. Many women find the strong stretching load on the nipples very uncomfortable. In DE 697 32 861 T2, on the basis of previous investigations, a number of physiological and psychological factors which have an influence on milk production and can bring it to a standstill are stated. There are two main factors

Highlighted: the stimulation of the breast to trigger the milk ection, which is usually caused by the jaw and the

Lips of the child takes place (it is a mechanical pressure exerted) and the actual sucking (it is a

Negative pressure applied), which occurs when the child drinks at the breast.

Furthermore, in the cited document a good overview of the prior art for various

Embodiments of breast pumps comprising a breast cup are given (US 5,049,126, US 4,680,028, EO 198,469, WO 92/07493, US 4,064,851, EP 727,234, US 2006/0111665 AI, US 2006/0106334 AI).

697 32 861 T2 discloses a milk suction device for the female breast comprising a breast cup having various stimulating elements arranged to serve to stimulate the nipple as well as an area immediately around the nipple and a breast area 2.5 to 3 cm away from the base of the nipple and connected to a vacuum source and a pressure source such that a pulsating wave is generated from the chest area farthest from the nipple toward the part of the breast closest to the nipple.

DE 881 20 30 U1 discloses a breast milk pump with a flexible funnel which can be placed on the female breast, to whose inner funnel end a drainage channel for the extracted milk follows, the funnel and the discharge channel being connected to a vacuum device and being evacuated, and the funnel as a roll-up guard z is surrounded by a stiff support member.

DE 93 06 631 Ul discloses a conical, flexible suction for breast milk pumps, with a on the

Breastplate attachable mouthpiece and a neck piece for

Including the nipple part, whereby an overstretching of the nipples during the suction process by a perforated

Supporting wall to be avoided, and the neck part is connected to a vacuum-generating device. In DE 87 02 791 Ul an insert for breast pumps is described, which consists of a soft spring-back

Polymer material is made, the suction effect is caused by a connected pump.

A major disadvantage of the solutions described above is that when pumping, which is done by means of electrically or mechanically generated negative pressure, the chest

physiologically extreme by the very strong negative pressure is claimed and hardly or no mechanical pressure acts, which is essential for the promotion of the milk delivery. For many women, this can be very uncomfortable and associated with pain and injury to the breasts. at

Swelling of the breast, as e.g. when shooting the

Milk or damming occurs, it may be that neither the baby can properly breastfeed nor a pump is applicable, because it moves even more lymph fluid to the already dammed up Mamille. Also, the daily pumping time is relatively long, and in women with a fixed nipple structure, this type of milk production is very difficult to impossible. Furthermore, with a pumping duration of several weeks, the mummies can increase, which some women find unpleasant. Another disadvantage is the use of rigid or not suitable for all breast sizes

 Breast bells or funnels to catch the milk.

Furthermore, recent studies on the lactation of breast milk from the female breast have shown that babies on the chest exert a high degree of mechanical pressure, that even this pressure alone is sufficient to empty the chest, and that negative pressure (as caused by a pump is performed) plays a rather subordinate role.

Just the mechanical pressure by the infant causes in addition to the stimulation of the nerve endings a significant promotion of the amount of milk to be gained in a much shorter time than it only by the negative pressure of a

conventional breast pump is possible.

The object of the invention is therefore to provide a means with which in addition to the stimulation of the nipple (for effect A) and the effect B described above, the effective secretion of the milk can be effected without the need of strong negative pressure and the in order to

associated pain and problems in the woman, said the Milk is simultaneously completely and hygienically caught.

The object is achieved on the arrangement side, in that the breast shell is designed as a milking cuff in such a way that it has at least one flexible part, with which the milking cuff is pressed onto the female breast,

at least on the areola is tightly placed and is designed such that a manual, a lactation

causing milking pressure on the nipple and the

adjacent areas is executable. The term "milking pressure" refers to the mechanical pressure, which acts and is exerted on the breast analogously to the movements of the palate, tongue, etc. of the infant.

In this case, the flexible part of the breast cup of a soft elastic material, preferably silicone or

Rubber which is so flexible that it can enclose any breast size and shape, in particular the nipple and the adjacent areas (Figure 2) are enclosed so that the expressed milk injected into the breast and not into the environment.

In an advantageous embodiment of the invention, reinforcing rings and / or reinforcing struts can be formed in the soft-elastic material.

The flexible part of the breast cup can be designed such that with the fingers of one hand from the

 A tightly enclosed female breast can be grasped so that a manual, secretion-inducing milking pressure on the female breast is achievable, passing through the mother's fingers, as opposed to

conventional pump, a rhythmic, precisely metered milking pressure can be exerted on the areola / chest area and both stimulation of the nerves as well effective emptying promotion causes. The milking of the breast can take place in various ways, in particular with a "thumb-up-finger-down-method" (Fig.la), in particular a "two-to-ten-finger method" (Fig.lb). , in particular a "five-finger method" (Fig. 1c), thus becoming physiologically a rapid and lasting one

Milk ektion achieved. Swelling of the breast,

In particular, when shooting the milk or in case of congestion, it can also be easily applied a minute long gentle pressure on the areola to move away the stagnant lymph fluid. The applied milking pressure continues to cause a significant increase in the amount of milk that can be obtained in the same time. This leads - in addition to saving time - with sufficiently frequent use to the fact that the almost full potential of the mother for milk production is exhausted - if she wants. The flexible part of the breastshell may be designed as a kind of glove with protuberances for fingers of a hand (FIGS. 3a, 3b) such that the female breast / areola can easily be enclosed with the fingers of one hand and a manual, a lactation

causing milking pressure on the nipple and the

adjacent areas can be performed with your fingers.

The protuberances of the flexible part of the breastbone for the fingers of a hand may be formed such that at least the fingertips of the hand are receivable therein and the protuberances with their outwardly directed towards the female breast cavity form a cavity that the female breast flexible and sealing encloses. In this case, a flexible connection between the breast cup and the collected milk collecting receptacle can be formed, so that the milk by means of the

Milking pressure, which is carried out by the fingers of the hand, lactated from the nipple and the surrounding areas, can be collected in a collecting container.

In this case, the breast cup and the flexible connection can be formed in one piece and the transition from the breast cup to the flexible connection can be designed as a flexible, elastic drainage for the lactated milk.

The glove with protuberances (2) for the

Trained flexible part of the breast cup trained flexible part of the breast cup trained flexible, elastic process for the lactated milk should be arranged such that it does not hinder the manually executable, lactation causing milking and be connected to the receptacle via a flexible connection, for example, a hose. The flexible, elastic process for the lactated milk should at least have a length such that the collecting container can always assume an upright position, so that the woman can obtain the mother's milk in any

Body position, especially sitting, lying or standing, can perform.

The flexible detachable connection between the breast cup and the collecting container may be as a screw or

Plug connection be formed.

The breastbone can be combined with both

electric breast pump as well as in manual mode, each working with negative pressure and either to support by means of the effect C or

Serve milk removal.
