Description

Connecting element

The invention relates to a connecting element for ventilation tubes and the like, with first to third pipe sections, wherein the second and third pipe sections merge into the first pipe section in such a way that the connecting element is Y-shaped.

Such connecting elements are generally known in this way. They are usually made of a plastic material with a smooth surface. Corresponding corrugated hoses are then connected to the free ends of the connecting element, for example by pushing them onto the ends of the pipe sections. The first pipe section usually points towards the head of the patient who is to be ventilated.

In some cases, ventilators and accessories must be connected quickly. This is especially true for anesthesia during emergency operations.

However, due to the smooth surface of the connecting element, it can lead to your hand slipping on the smooth surface.

The invention is therefore based on the object of specifying a connecting element of the type mentioned at the beginning, which always enables easy and quick 0 sliding on and, if necessary, sliding off of corresponding corrugated hoses with technically simple means.

This object is achieved according to the invention in a connecting element of the type mentioned at the outset by grip strips which are placed on the outward-facing side regions of the second and third pipe sections.

This handle bar provides a secure hold when assembling.

The slip resistance of the handles can be further increased by providing the surface of the handles with ribbing.

The attachment of the first pipe section of the connecting element, which is directed towards the patient's head, to the corresponding hose can be made even easier by providing the end of each handle strip, which is directed towards the first pipe section, with a projection which essentially points outwards.

For inspection purposes or for the introduction of certain materials, the second and third pipe sections may be provided with first and second probe openings in the surfaces without handle strips.

These probe openings can be surrounded by first and second pins extending outwards in a column-like manner.

To adapt to different connections or probes, the first and second pins can have different lengths and diameters.
25

These can of course be provided with cover caps that can be permanently attached to the connecting element.

0 According to a further embodiment of the invention, the free ends of the second and third pipe sections are provided with first and second connecting pieces, preferably of identical size. However, the first pipe section can also be designed in the form of a third connecting piece, whereby this first 5 pipe section or this connecting piece can have the greatest wall thickness of all pipe sections and connecting pieces. This serves to ensure the strength of this connection side.

Preferably, the connecting element consists of a transparent plastic and is formed as an injection-molded part.

Further features and advantages of the invention will become apparent from the following description of an embodiment and from the drawings to which reference is made. They show:

An embodiment of a connecting element 10 will now be described with reference to Figures 1 to 6, in which identical parts have been given identical reference numbers. 35

The connecting element 10 consists of a first pipe section 14, to which second and third pipe sections 16 and 18 are connected.

run.

The free ends of the second and third pipe sections 16 and 18 have first and second connecting pieces 30 and 32, respectively, onto which, as can be seen from Figure 1, ventilation tubes 12 are attached.

The first pipe section also essentially consists of a third connecting piece 14, which has the greatest wall thickness of all the pieces, as can be seen in Figures 3, 5 and 6.

The first and second connecting pieces 30 and 32 have a larger inner diameter than the second and third pipe sections 16 and 18 of the connecting element 10.

Of course, all connection pieces 14, 3 0 and can be designed differently for different hoses or different ventilators. 20

In order to be able to handle the connecting element 10 safely and quickly, handle strips 20 are arranged on the outward-facing sides of the second and third pipe sections 16 and 18.

These grip strips 20 are preferably formed in one piece with the connecting element 10 and have corrugations 22 to further increase the grip strength, which are shown schematically in Figure 2.

0 Since the hose leading to the patient often has to be connected quickly and safely to the connecting element 10, the ends of the handle bars 20 pointing towards the first pipe section 14 are each provided with a projection 24 pointing essentially outwards. The user's fingers can find an even better grip on these projections 24 5 when the first pipe section 14 is to be pushed onto the corresponding hose section pointing towards the patient.

For the introduction of necessary agents and/or for checking the breathing air, the second and third pipe sections 16 and 18 are provided with first and second probe openings 26 and 28.

These probe openings 26 and 28 can be surrounded by first and second pins 26a and 28a extending outwards in a column-like manner.

The first pin 28a has a smaller diameter and a greater length than the second pin 26a. This design of the first and second pins 28a and 26a is adapted to the devices to be connected.

The first and second pins 28a and 26a can of course be closed with corresponding cover caps 34, 36, which can be attached to the connecting element 10 in a captive manner, for example by means of a plastic ring 38 in the area where the second and third pipe sections 16 and 18 meet, from which plastic bands 40, 42 are guided to the cover caps 34, 36. This cover arrangement is shown in Figure 7.

The connecting element 10 is preferably made of transparent plastic material.
25

A favorable manufacturing method is provided when the connecting element 10 is an injection-molded part.

With the help of the handles on the outer surface of the second 0 and third pipe sections of the connecting element, quick and safe handling is always possible.
