Embodiment Construction

[0025] Figures 1 to 3 show a laryngeal mask designed according to the present invention. The laryngeal mask is composed of two main components, namely the laryngeal mask head 1 and the supraglottic tube 2 connected to it. These two parts can be made separately or together in one piece. Observing the back side of the laryngeal mask head 1, as shown in FIG. 1, it can be seen that the cover plate 9 is located in the middle, and the cover plate is a one-piece component of the laryngeal mask head and connected to the supraglottic tube 2. The breathing space 3 is located under the cover 9 and therefore along the ventral direction. This breathing space 3 is bounded by a circumferential cuff 4 on all sides. The esophageal channel 5 extends in the cover plate 9. This is obviously only an optional possibility and is not necessary for implementing the present invention. The esophageal channel 5 enters the laryngeal mask head 1 through 5'. Accordingly, there is an open channel guided ...

Abstract

Especially in emergency situations there is a need for a laryngeal mask head with a ventral breathing space (3) with a cuff (4) surrounding it that does not need to be inflated to match size. Here, the laryngeal mask head has non-pneumatic devices (6, 7) for size adaptation in the medial-lateral direction and in the ventral-dorsal direction (12). Preferably, the device is realized by an open, elastic groove (10, 20) extending in the direction of extension of the cuff (4).

Description

Technical field [0001] The present invention relates to a laryngeal mask head, which comprises a cover plate provided on the back and a supraglottic tube connected with the cover plate. The laryngeal mask head has a cuff surrounding the abdominal breathing space. Background technique [0002] Various laryngeal masks with different construction principles are known and available on the market. Most laryngeal mask heads have a cover plate connected to the supraglottic tube on the back. There is a breathing space surrounded by a cuff on the ventral side of the head of the laryngeal mask. In most known laryngeal mask heads, the cuff is inflatable. For example, US 5,878,745, US 2003 / 0037790 or US 7,040,322 show typical examples of such a laryngeal mask, the laryngeal mask head has a cover plate provided on the back and a ventral breathing space, wherein the breathing space is inflatable Cuff surrounds. There are basically few laryngeal masks that do not have an inflatable cuff on ...
