This purpose is achieved by using a valve having the characteristics of the first item of the patent application. According to the invention, there is a room having a seat and a round body. The film is arranged above the valve seat and is dense... The seat is closed when the seat is closed, wherein the seat is closed. The valve body has an opening, and the film which is interlaced with each other 掀 畲 畲 构成 构成 构成 构成 。 。 。 。 。 。 。 。 。 。 。 。 The membrane of the valve body has an opening of La County, and is evenly distributed along the Bodhisattva _ round eight & a long length. The center of the circle is the same as the center of the membrane. The longitudinal extension of the circle in the gate of the La County is long ^^ Designed in an arc shape that is spaced apart. = The circle extends. They use the frame strips to each other'. The elongated opening constitutes a common ring which is several times smaller than the smaller diameter of the solid core and the ring is provided with a frame strip and the area of the frame strip is designed to be thinner. It is preferable to have exactly three such open frame strips, so the film 1378805 is held in a three-point suspension manner. The thinner region can be a tight opening or thinned location, or a combination thereof. This thinned area is used to counteract the stress and thus the functionality of the valve is ensured even after heating and cleaning. Good results were achieved with a τ-shaped close opening. There is an advantage in combining the thinned areas with a tight opening, that is, the frame strip constituting the joint of the valve is sufficiently flexible even after washing to round the film (which is constituted by the elongated opening) fast enough And the ground up and down according to the standard. A cylindrical envelope is preferably formed on the membrane which is swelled up through a collar of the valve seat (Kragen). If the inside of the envelope has an axially extending engraved portion and/or a circumferential groove, the stretching during cleaning can also be avoided. The above-described valve of the present invention is preferably used in the above-described types of breastshield sets in the embodiments described above and below. However, it can also be used for other articles, in particular medical products, for example for use as a drainage bag to draw body fluids, or for various suction hoses. It is therefore another object of the present invention to provide a breastshield set that can be manufactured as cheaply as possible. This purpose is achieved by taking advantage of the characteristics of item 18 of the patent application. In order to comply with the hygienic regulations for multiple use, the breastshield set is generally disposable and can be used as a high temperature dad (aut〇klavieren). However, recently, the hygiene requirements for saliva and personal use have increased, so the demand for a blister pack has been sizzled, and the blister pack can only be used for a limited number of times. This multiple use is generally limited to a single day of beta 1378805. The present invention is directed to providing a breastshield set that can only be used a limited number of times. This object is achieved by using a breastshield set having the features of claim 22 of the scope of the patent application. At least a part of the sucking milk 5, the Bush and the 'Zhuo group of the present invention cannot be treated by autoclaving. If this: divided into valve body ' is enough. If the valve body is used as an autoclave, it will be stretched, and the functionality of the entire breastshield set will no longer be ensured due to lack of sealing and an increase in ineffective volume. It is also possible to construct a number of knives (for example, valve seat, suction cap joint and suction cap drain 4) from materials that cannot be autoclaved. It is of course also possible to manufacture other accessories, such as suction lines, from materials that cannot be autoclaved. The solution of the invention is obtained from the following observations. In general, the hospital (Spi (8) er)'s baby-care station (Saug Hngsstati〇n) or maternity station (W0Chnednnenstatlon) is self-cleaning, so the mother can reuse their own set of breastshields used to date. In addition, the mother or Mem can be controlled to see how many times the breastshield has been used and to dispose of it after a correspondingly short period of time. The suction cup that can be used for autoclave treatment. The group is usually cleaned in another department, so they have to leave the baby-care station or the maternity station, often arrive at the station the next day, and can no longer control the above. . If the breastshield set is prevented from being autoclaved at this time, it can be used for a limited number of times as desired. However, due to the fact that the valve body must not be autoclaved, the choice of materials is greatly limited. The material that is suitable is an elastomeric polymer (τρΕ). However, this material has a high requirement for the shape of the valve body, and it does not pull 1378805 when it is cleaned. These requirements are met in accordance with the scope of application for the scope of patents 丨~17. Other advantageous embodiments are found in the dependent claims. Hereinafter, the subject matter of the present invention will be described by way of a preferred embodiment of the drawings. [Embodiment] Fig. 1 shows a breast shield set of the present invention. Yes—The breastshield joint (2) is screwed onto the milk collection container (1). On the other side of the breastshield joint (7), a suction cap (3) [which has a suction cap funnel (3〇)] is attached to the other side to hold the suction line (4). If the breastshield joint portion (2) is not used, for example, when the milk collection container (1) is full, a closure cap (5) can also be screwed onto the milk collection container (1). Figure 2 shows how the individual components described above are connected to each other. The milk collection container (1) has a neck (1) having an external thread (11) to which a threaded insert (4) having an internal thread (10) of the breastshield joint portion (7) can be screwed. A - joint neck (9) is formed through the short neck (24) onto the job insert (10). The f neck (21) has a receiving opening (25). The "joining neck" (31) of the breastshield (3) can be inserted into the receiving opening (25). On the opposite end of the joint neck (9) there is a plug receptacle (not shown) for direct connection to the suction line (4). The hose (4) can be connected to the outside by means of a light fitting (4G). Pump. The breastshield (3) can also be integrally formed on the breastshield joint portion (7). Furthermore, the breastshield joint portion (2) may also have a receiving portion for accommodating a manual or electric motor without the suction pipe plug. As shown in Fig. 2, in the breastshield joint (10) and the milk collecting capacity: the body has a -" it has a seat (6), and there is - fixed on the valve seat should be located here In the breastshield joint part (2). The valve seat (6) can be formed on the suction cap joint portion (2) or can be inserted into an associated receptacle (23). The associated receptacle (23) in the crucible 3 is the inwardly projecting neck of the neck type V (26) which represents the upper stop for the milk collection container or bottle.

It has a cover surface (61) (which is round 7 and substantially or absolutely flat) and a surrounding collar (60) formed on it. The i-face (61) has a central opening (") and a peripheral opening (65). The central opening (65) and constituting a common circle, wherein the point coincides with the center of the circular cover. Preferably there are exactly three peripheral openings (65), wherein the common circle is interrupted by the frame strip (66). As best shown in Figures 4c and 4e, the cover surface (61) protrudes beyond the collar (6〇) at the edge (62) around the square. In addition, the collar (6〇) is on the moon cover (61). The lower region has a surrounding ring (Wulst) (63). This portion can also be marked (beschriften). A related example is shown in Figure 5 (67). Valves are shown in Figures 5a to 5k Body (7) ^ This valve body (which can be strewed outwards in the above-mentioned valve seat. The valve uses the groove (27) or should be retained by the first groove (77) or the second groove (78) The cap body (2) is substantially the same shape as the valve seat (6), in other words, it has a substantially flat circular membrane (70) which is surrounded by a cylindrical shape Shell (75 Enclosed, but the outer side of the membrane (70) [it faces away from the valve seat (6)] may also have a hairy conjunctiva (70) with some areas (74) designed to be weak. These weak parts are due to these areas on the one hand (74) The material thickness is small, as shown in Figure 5a. On the other hand, due to the tight opening (73), these thinner regions or depressions (74) are thickened and transition to the rest of the membrane. Figure 5a It can be seen that the edge of these areas (74) is designed as a ramp. This can also be seen in Figure 5e. 10 1378805 Flat. But the inside of the body (7) has at least one (preferably two _8). Furthermore, 'at least the notch (10), as shown, is perpendicular to the core-wrapped groove (77) (78) and extends parallel to the cylindrical t-axis. This notch preferably begins at the groove (78) close to the membrane and terminates. On the outer edge of the membrane (75). In this example there are three notches (76) 'they are in the region of the τ-shaped opening (73) and preferably in the line defined by the foot of the opening. 5d and 5h. The grooves (77) (78) and the notches (76) help to avoid the case of the shell stretching when the temperature changes (especially during sterilization).
如果閥體（7)設在閱座（6)上，如圖4d及圖5d所示則 閥座⑻的中心開口（64)與周圍開口（65)被圓形膜蓋片[它們 位在拉長的開口（71)内]蓋住。而拉長的開口（71)與緊密開 = (73)則位在閥座（6)的外緣區域。如此該閥在正常壓力 時係關閉纟。如果此時’作用到膜蓋片上的麼力升高，則 膜蓋片均勻地南集奶容器（1)内部空間拱起，並使閥座（64) 的開口（64)開放。如此閥體（7)的開口亦遠離其倚靠面，故 從閥一邊到另一邊造成通道。如果作用到膜内側的壓力解 除’則该膜再下降到閥座，並將止回閥關閉。 上述吸奶罩組的個別部件宜由一種可消毒及可高壓爸 處理的材料[例如聚丙烯（PP)]製造。但至少一部分（特別是 閥體）由一種不能作高壓爸處理的材料[例如一種熱塑性彈 性體（TPE)]製造。最好只有閥體由這種材料製造。 雖然本發明的閥在說明書中係用於吸奶罩組，但它也 可用於其他方面，例如在排液袋（Drainagebeutel)或排液容 器以將體液吸出，或用於真空軟管或其他醫學或其他的裝 12 ^78805 置。 在圖6a〜6c顯示闕體（7)的第二較佳實施例。它可配 合上述闕座（6)使用。一直到一外突環（79)(wulst)為止，該 閥體的設計都和上述閥體（7)第一實施例相同。此外，突環 . (79)宜繞函殼（75)的整個周圍延伸。但該突環（79)也可中斷 成一個個部段。同樣地，它亦設在與膜（70)相鄰的函殼（75) 邊緣區域中。由於有此突環（79)，閥體（7)可較容易地用手 φ 從閥座（6)鬆開，因為該突環（79)使表面較好握持，如果不 用該突環（79)[或者除了該突環（79)外同時]另外也可使用一 條槽。同樣地，函殼表面也可設毛結（N〇ppen)、凹陷部或 轴向延伸的肋。 本發明的閥可廉價而簡單的製造，在使用上可靠，且 在較大溫度變動時也很少會變形。 【圖式簡單說明】 圖1係該吸奶罩組的立體圖，包括集奶容器、吸取 路及封閉蓋； 圖2係圖1的吸奶罩組的分解圖； 圖3係一吸奶罩接頭部的立體圖； 圖4a係一閥座的立體圖； 圖4b係圖4a的閥座的另一立體圖； 圖4c係圖4a的閥座的側視圖； 圖4d係圖4a閥座的上視圖； 圖4e係絰圖4a的閥座的一部分的放大橫戴面圖； 圖5a係一閥體的側視圖； 13 1378805 圖5 b係圖5 a的間體的側視圖， • 圖5c係經圖5b閥體沿A-A的橫截面圖； 圖5 d係圖5 a的間體的底視圖； 圖5e係圖5a的閱體的立體圖， 圖5f係圖5a的閥體的另一立體圖； 圖5g係圖5b的一放大部P視圖； ' 圖5h係圖5d之一放大部Q視圖； 圖5 i係圖5 c之一放大部X視圖； • 圖5k係圖5c的一放大部Y視圖； 圖6a係依第二實施例之一閥體側視圖； 圖6b係經圖6a的閥體的橫剖面圖； 圖6c係圖6b的一放大部視圖。 【主要元件符號說明】 (I) 集奶容器 (10)頸 (II) 螺紋 ® (2) °及奶罩接頭部 (20) 螺紋嵌上物 (21) 接頭頸 (22) 内螺紋 (23) 閥容納部 (24) 頸 (25) 容納開口 (26) 止擋部 14 1378805If the valve body (7) is placed on the reading seat (6), as shown in Figures 4d and 5d, the central opening (64) of the valve seat (8) and the peripheral opening (65) are covered by a circular membrane [they are in the pull Cover the inside of the long opening (71). The elongated opening (71) and the tight opening = (73) are located in the outer edge of the valve seat (6). Thus the valve is closed at normal pressure. If the force acting on the film cover sheet rises at this time, the film cover sheet uniformly bulges the inner space of the south milk collection container (1) and opens the opening (64) of the valve seat (64). Thus, the opening of the valve body (7) is also away from its abutment surface, thereby causing a passage from one side of the valve to the other. If the pressure applied to the inside of the membrane is removed, the membrane is lowered again to the valve seat and the check valve is closed. The individual components of the above described breastshield set are preferably made of a sterilizable and high pressure dad-treated material such as polypropylene (PP). However, at least a portion (especially the valve body) is made of a material that cannot be treated by high pressure dad [e.g., a thermoplastic elastomer (TPE)]. Preferably only the valve body is made of this material. Although the valve of the present invention is used in the specification for a breastshield set, it can also be used in other aspects, such as in a drain bag or drain container to draw body fluids, or for vacuum hoses or other medical or Others installed 12 ^ 78805. A second preferred embodiment of the cartridge (7) is shown in Figures 6a to 6c. It can be used with the above seat (6). The design of the valve body is the same as that of the first embodiment of the valve body (7) up to an outer ring (79). In addition, the collar (79) should extend around the entire circumference of the shell (75). However, the collar (79) can also be interrupted into sections. Similarly, it is also located in the edge region of the envelope (75) adjacent to the membrane (70). Due to the collar (79), the valve body (7) can be easily released from the valve seat (6) by hand φ because the collar (79) allows the surface to be better held, if the collar is not used ( 79) [Or at the same time as the ring (79)] Alternatively, a groove can be used. Similarly, the surface of the shell may also be provided with a knot, a recess or an axially extending rib. The valve of the present invention can be manufactured inexpensively and simply, is reliable in use, and is less likely to deform when a large temperature fluctuates.
