Abstract
The main function of the device for extracting breast milk in a lying position is suction of the breast to extract milk for storage and subsequent use. The main feature thereof is that the device operates when the woman is lying down, both face up and on one side. Technically, this is achieved by means of a commercial suction pump and the extractor device developed acts as a complement to carry out the task with additional use of the electric suction pump. The use is for lactating women and the use thereof is domestic. Although various extraction devices are available on the market, none is designed to function when the woman is lying down. This situation in which a lactating woman would prefer to be lying down occurs, for example, when the woman has previously undergone surgery, for example a caesarean section, which obliges the woman to be lying down when the milk is extracted, although many women without this condition may also enjoy lying down while breast milk is being extracted.

El uso es para mujeres en estado de lactancia y su uso es doméstico. Si bien existen diversos dispositivos extractores de leche materna en el mercado, ninguno está diseñado ni funciona cuando la mujer está en posición recostada. Esta situación de una mujer lactante que preferiría estar recostada se da por ejemplo cuando la mujer tuvo una operación previa como una cesárea, lo cual la obliga a estar recostada cuando se extrae leche, aunque también muchas mujeres que no tienen esta condición pueden disfrutar de estar en posición recostada mientras se extrae leche materna. The use is for lactating women and its use is domestic. While there are a variety of breastmilk devices on the market, none are designed or operated when the woman is in a reclining position. This situation of a lactating woman who would prefer to lie down occurs for example when the woman had a previous operation such as a cesarean section, which forces her to lie down when expressing milk, although also many women who do not have this condition can enjoy being lying down while expressing breast milk.

The breast pump (1), has several parts that make it up, these are conical body (4), suction chamber (5), suction seal cone (5), among others.
El Cuerpo cónico (4), tiene dos paredes, una interior (4I) y otra exterior (4E), y tiene una distancia entre dichas paredes. El cuerpo cónico es la estructura principal, tiene dos paredes (4I, 4E) con una separación interna de tal manera que queda una -cavidad interna con distancias variables para contener la leche. La leche puede ser contenida y no se derrama debido a la conicidad y a la elevación de las paredes internas de la parte inferior del cuerpo cónico, El material es polipropileno virgen, grado alimenticio y sanitario, el cual, al ser una resina termoplástica, es impermeable a líquidos, entre ellos el agua y la leche. El ángulo interno (8) y las formas del cuerpo cónico están determinados por las pruebas de diversos diseños que se desarrollaron y probaron en el proceso de invención. La forma y los ángulos de las paredes responden a la necesidad de acercarse lo más posible al pezón de la mujer para maximizar la succión de la bomba, con ello la extracción de leche, responden también a la necesidad de contener la leche sin tirarla, para después de la extracción, pasarla a otro contenedor para su almacenamiento o su consumo.
Dentro del cuerpo cónico (4) se encuentra la cámara de succión (5), esta es necesaria porque sin ella el extractor no extraería la leche, funciona bajo el principio de baja de presión en un volumen confinado y con ello la producción de vacío para compensar el volumen desplazado. La succión viene de la bomba comercial (2) a la cual se conecta el extractor de leche. La altura de la cámara fue esta lo más compacta posible para minimizar el volumen de aire por desplazar en la succión de la bomba, si es menos volumen, se acerca más al pezón, lo que evita chorreo y maximiza la captación de gotas de leche, y al ser el mínimo volumen, maximiza también la succión. El cono de cierre de succión (6), se ensambla para cerrar la cámara de succión (5), La altura del cono está determinada, como todos los elementos por las diversas pruebas que se hicieron y por la optimización formal para bajar costos de manufactura y uso de material. El cono, al ser de material suave, sirve como sello entre el pezón y el cuerpo cónico, dando comodidad al tacto, pero su función principal es amoldarse lo más posible a la forma del seno en cuestión para evitar la entrada de aire a la cámara de succión y con ello la perdida de vacío y succión. The conical body (4) has two walls, an inner one (4I) and an outer one (4E), and it has a distance between said walls. The conical body is the main structure, it has two walls (4I, 4E) with an internal separation in such a way that there is an internal cavity with variable distances to contain the milk. The milk can be contained and does not spill due to the taper and the elevation of the internal walls of the lower part of the conical body, The material is virgin polypropylene, food and sanitary grade, which, being a thermoplastic resin, is waterproof to liquids, including water and milk. The internal angle (8) and the shapes of the conical body are determined by tests of various designs that were developed and tested in the invention process. The shape and the angles of the walls respond to the need to get as close as possible to the woman's nipple to maximize the suction of the pump, thus the milk extraction, also respond to the need to contain the milk without throwing it, to after extraction, transfer it to another container for storage or consumption. Inside the conical body (4) is the suction chamber (5), this is necessary because without it the extractor would not extract the milk, it works under the principle of low pressure in a confined volume and with it the production of vacuum for compensate for the displaced volume. The suction comes from the commercial pump (2) to which the breast pump is connected. The height of the chamber was as compact as possible to minimize the volume of air to be displaced in the suction of the pump, if it is less volume, it comes closer to the nipple, which prevents dripping and maximizes the collection of milk drops, and being the minimum volume, it also maximizes suction. The suction closing cone (6), is assembled to close the suction chamber (5). The height of the cone is determined, like all the elements, by the various tests that were carried out and by the formal optimization to lower manufacturing costs. and use of material. The cone, being made of soft material, serves as a seal between the nipple and the conical body, giving comfort to the touch, but its main function is to conform as much as possible to the shape of the breast in question to prevent air from entering the chamber of suction and with it the loss of vacuum and suction.
Para el correcto funcionamiento del extractor de leche, son necesarios, Una bomba de vacío (2), la mayor succión que la bomba sea capaz de generar, debido a que es necesaria para lograr extraer la leche del seno. Si la mujer que está usando la bomba lo siente incómodo, puede variar hacia abajo la fuerza de la succión, esto es un tema de comodidad que es determinado por cada usuaria.
For the correct operation of the breast pump, a vacuum pump (2) is necessary, the greatest suction that the pump is capable of generating, since it is necessary to achieve the extraction of milk from the breast. If the woman who is using the pump feels uncomfortable, the suction force may vary downwards, this is a comfort issue that is determined by each user.
