DE20319519U1 - Stethoscope with two branches each with hearing piece, clip-tube, coupling ends, operating ends, rubber tube, thrust piece and concave outer and inner concave surfaces - Google Patents

Abstract

Each of the two branches (20) of the stethoscope (2) has an elongated hearing piece (22) one end (221) of which fits into the wearer's ear, while the other end (222) is connected to a curved clip-tube (21) with coupling end part (210). A flexible operating end part (211) is opposite the coupling end part. .A rubber tube (23) is fluidally connected to the branches A thrust piece (212) gives each branch a concave outer surface (2121) facing a concave inner surface (2122).

Description

The invention relates to a stethoscope, especially a stethoscope that is put on with just one hand and can be removed.

A conventional stethoscope owns a pair of pipe pieces and a Y-shaped one Rubber hose with a first hose area and two second Hose areas connected to the first hose area are. The first tube area has a distal end that to a hearing aid for the Breast connected. The second tube areas are each with one of the pipe pieces connected.

In practical use, a carrier stops first the pipe pieces and then sets the pipe pieces in the ears of the wearer or removes them from the ears using both hands. As a result, the conventional stethoscope prove impractical when used.

It is therefore the task of the present Invention to provide a stethoscope that created with only one hand and can be removed.

According to the present invention a stethoscope has the following:

• - on Pair of branches or pipe pieces with each
• - one elongated Hörrohrteil with a first end that can be inserted into an ear of a wearer and a second end opposite the first end, and
• - one curved clip-tube part with a coupling end area, which with the second end of the hearing tube part is connected, opposite a flexible actuating end region from the coupling end area, and a curved abutment intermediate area, the coupling end area and the actuation end area with each other links; and
• - one Rubber hose attached to the actuation end areas the clip pipe parts of the pipe pieces connected and with the pipe pieces is in fluid communication.

The abutment intermediate area of the clip tube part from each of the pipe pieces has a concave outer surface, which faces away from the other of the pipe sections, and one convex inner surface, facing the other of the pipe sections.

The abutment intermediate areas of the clip pipe parts of the pipe pieces lie against each other.

The operating end areas of the clip tube parts of the pipe pieces form a space between them for compression.

The operating end areas of the clip tube parts of the pipe pieces can pressed together be so that they the hearing tube parts induce itself from a clamping position in which the first ends of the hearing tube parts of the pipe pieces in the ears of the wearer can be used to a release position in which the first ends of the Hörrohrteile of the pipe pieces from the wearer's ears are removed.

Other features and advantages of present invention will become apparent from the detailed below Description of the preferred embodiments with reference to the attached Drawing.

Show it:

1 a partial perspective view of the first preferred embodiment of a stethoscope according to the present invention;

2 a partial perspective view illustrating how hearing tube parts of a pair of tube pieces of the stethoscope of FIG 1 be moved to a release position; and

3 a partial perspective view of the second preferred embodiment of a stethoscope according to the present invention.

Before a more detailed description of the present Invention is noted that like components are always identified with the same reference numerals in the present case.

With reference to 1 is the first preferred embodiment of a stethoscope 2 shown and has a pair of branches or pipe pieces according to the present invention 20 and a rubber tube 23 on.

Each of the pipe pieces 20 has an elongated hearing tube part 22 and a bent clip tube part 21 on. The hearing tube part 22 every pipe section 20 has a first end 221 for insertion into a wearer's ear (not shown) and a second end 222 opposite from the first end 221 , The curved clip tube part 21 every pipe section 20 has a coupling end area 210 that with the second end 222 of the hearing tube part 22 is connected, a flexible actuating end region 211 opposite from the coupling end area 210 , and a curved abutment intermediate area or joint area 212 , the coupling end portion 210 and the actuation end portion 211 connects with each other.

The rubber hose 23 has an upper end that connects to the actuation end areas 211 the clip tube parts 21 of the pipe pieces 20 is connected and with the pipe pieces 20 is in fluid communication, and a lower end which is connected to a hearing attachment (not shown).

It is noted that the abutment intermediate area 212 of the clip tube part 21 every pipe section 20 a concave outer surface 2121 has that of the other of the pipe sections 20 is turned away, as well as a convex inner surface 2122 that the other of the pipe sections 20 is turned.

The abutment intermediate areas 212 the clip tube parts 21 of the pipe pieces 20 lie against each other. The actuation end areas 211 the Clip-tube parts 21 of the pipe pieces 20 form a free space 213 for squeezing between each other.

The actuation end areas 211 the clip tube parts 21 of the pipe pieces 20 can be pressed together so that the hearing tube parts 22 are caused to come out of a clamping position as shown in 1 in which the first ends 221 of the hearing tube parts 22 of the pipe pieces 20 can be inserted into the ears of the wearer, in a release position as shown in 2 to move in the first ends 221 of the hearing tube parts 22 of the pipe pieces 20 away from the wearer's ears.

The abutment intermediate area is preferred 212 of the clip tube part 21 every pipe section 20 a rectangular cross section, so that the abutment intermediate areas 212 the clip tube parts 21 of the pipe pieces 20 can have a comparatively large contact surface.

3 represents the second preferred embodiment of a stethoscope 2 ' according to the present invention, which is a modification of the first preferred embodiment. In this embodiment, the abutment intermediate region of the clip tube part 21 ' every pipe section 20 ' a slip brake cover applied to him 5 on.

In summary, the hearing tube parts of the pipe sections 20 . 20 ' are caused to move away from or towards each other by moving the operating end portions 211 the clip tube parts 21 . 21 ' of the pipe pieces 20 . 20 ' compresses or releases, so that for putting on and taking off the stethoscope according to the invention 2 . 2 ' only one hand of the wearer is needed.
