DETAILED DESCRIPTION OF THE INVENTION Many stethoscopes in use today have nine double
chest microphones 07 with switching pulp to selectively connect the sound to a low frequency
bell or high frequency tire fram. 2) (dualtkzsl-piItyjνtofmlcro door hone). Both the bell and the
diaphragm are required when the skilled person desires to auscultate 8 occupational problems in
close proximity to the heart. For example, tire fram is useful for auscultating heart sounds in the
100-2000 Hz range. (The earfram may be large, as it does not have to be in intimate contact with
the patient's skin and only needs at least a portion of the diaphragm surface to touch the
patient's skin. On the other hand, the bell-like part should be in close contact with the patient's
skin. It is because the skin itself is used as ear frum. Thus, bells are useful at low frequencies in
the range of 5O-150az. It has been found that the deeper the bell, the better the perception in
this frequency range to the auscultator. In prior art stethoscopes, it was necessary to offset the
bell axis by 90 "from the axis of the tysephram in order to obtain a deep bell. Pulp is placed at
the intersection of the bell axis and the axis of the diceps ram. The bell or tire fram can therefore
be closed to extinguish the output when not in use. Although this device creates an excellent
stethoscope with high sound quality8, the microphone is bulky, the entire microphone 0 is very
heavy, and as a result, the use becomes inconvenient. Furthermore, such a stethoscope requires
the use of both hands when switching from a microphone state to a -1 doctor or a stethoscope.
That is, if the apologist is using acupuncture isefram and wishes to use a bell, he must use the
open hand for the switching operation. Thus, if a patient needs support, a nurse or other
attendant must be present. Furthermore, this prior art stethoscope had a sting that it was difficult
to use two microphone states in a narrow space such as under a shirt or in a bra. For this reason,
it is almost always necessary for the patient to at least partially take off the clothes in order for
the doctor to auscultate the patient's heart in both microphone modes. Recently, it has become
common for bells and tie-sembrams to have co-axially aligned dual microphones on opposite
sides of the microphone body.
Such a stethoscope is shown, for example, in U.S. Pat. No. 3,472,335 which has been proposed by
the present inventor. In this case, the movable switching medium bar is disposed near the axis of
the microphone 07 so that one hand can be used when the auscultator switches from one
microphone state to another. However, to be completely practical, the microphones present a
slight disadvantage. That is, in order to expect the thickness of the microphone to be practically
difficult to handle, it is necessary to make the bell-shaped portion shallow. As a result, the
stethoscope can not detect and transmit the sound emitted by the D heart at the lowest desired
frequency. Therefore, it is necessary to provide a dual microphone 0-phone with a bell-shaped
portion of maximum practical depth. Such a microphone is desirable to be relatively small and
bulky in order to be comfortable for the person to which it is applied and to facilitate carrying of
the stethoscope. It is also preferred that such a stethoscope minimize the overall height of the
stethoscope so that the patient can be easily auscultated. The present invention seeks to
eliminate the drawbacks of the prior art and to provide a stethoscope microphone which meets
the above-mentioned need. Furthermore, the present invention is such a stethoscope, which
allows the use of plastic injection molded bells, thereby reducing the coldness felt by the patient
when the stethoscope is applied to the patient's skin. It is something to be reduced. In the
preferred embodiment of the present invention, the stethoscope microphone 07 Oshi is
configured such that the bell-like axis is neither perpendicular nor coaxial to the di-sephram axis.
In the present invention, the axes intersect at an acute angle, and the preferred angle between
the axes is in the range of about 20-70, more preferably about 30. Because the bell is offset from
the axis of the dicefram, it is possible to place the bell near the front of the microphone 0, and it
is extremely easy for the auscultist to feel uncomfortable with the patient and to make the
microphone a patient. It is possible to make it come in close contact with the skin, and to make
the microphone invert in the narrow part of the clothes rounding-off 12 of the use of the
dicefram. Furthermore, the present invention can use a nine-round-type pulp spool supported
within the pulp body substantially over the desired circumference, so that the pulp spool can be
extremely airtightly sealed to its valve seat, and sound can be generated in the microphone.
Avoid leaks and poor sound transmission. The sound can be rigidly connected to the pulp spool,
and the sound wave can travel through the pulp screw to a tube in communication with the
binaural canal.
The bushing also acts as a lever for facilitating rotation of the pulp spool tube within a
predetermined range where the valve clamps make a sound connection with the bell or tire fram.
In other words, the auscultator is able to perform both of the support of the microphone 07 and
the switching from the listening mode to the other mode 13 to the other mode with only one
hand. Thus, while holding the patient with, for example, the left hand, the doctor can use the
right hand to both hold the microphone and switch on the sound connection when reversing
from one listening mode of the microphone 0 to the other. If desired, the pulp spool can be
configured to releasably lock with the sound holes connected with the holes, so that it is not
necessary for the auscultiser to hold or restrain the pulp connection. An embodiment of the
present invention will be described below with reference to the drawings. This will reveal various
important unique features of the microphone D phone of the present invention. Similarly, it will
be appreciated that the present invention may take on a wide variety of modifications within the
scope of the present invention in addition to the embodiments described below. As shown in FIG.
1, the stethoscope microphone (2) can optionally be attached to a flexible brass tube which can
be fitted in a known manner to the auscultator's ear. It is conductively connected to (d). With
reference to FIGS. 1-4, the microphone 0 υ q υ includes a first body member CL 有 す る having
a pair of upstanding ears or flanges, of which only one is shown in FIG. It is done. A periphery (2)
is formed on the body member aη, and a rim (J) is formed on the periphery to seal the tire fram
between the link and the body member. It is attached by screwing or other appropriate means. As
a result, the volume (goods) is the tie? It is formed in the form of a film and a non-member and is
in communication with the first through hole of the image bar. On the upper surface of the nondiscrete member, various stationary structures are provided including a (second) 15-body
member 6) stationary support cow-(2) with a guide (2). The first body member (b) may be made
of plastic, stainless steel or any other suitable material, and the second body member may be
injection molded of plastic if desired. Since the microphone 0 phone is usually carried by hanging
or in the pocket on the neck of the user, if the body member is made of an injection-molded
product, the bell shaped portion will The patient's body does not feel too cold.
The second body member may be integrally formed with a bell-like portion having a lip. It has a
central chamber (FIGS. 3 and 4) developed around a bell-shaped axis. An opening weir is formed
on the inner wall of the bell-shaped 16-part (good), and the inside of the bell-shaped part is in
communication with the listening sound through-hole in the body media shaft. The table 61 is
also in communication with the through hole so that a horizontal cylindrical hole is formed. The
through hole is in communication with the through hole, and the through hole is the Bopui
member Qη and the ring is the When assembled as shown in FIGS. 3 and 4, it is in sealing
communication with the through hole. An opening is provided which grinds from the cylindrical
hole to the rear of the insulating member φ, and the sound g0 penetrates the opening and is
connected to the tube (2). The sound (C) is rigidly connected at the inner end of the pipe to a
storage-like pulp spool 4 which is inserted into the hole-under the hole and the hermetic seal.
Radial through holes 6]) are provided on one side of the sleeve 4 in order to be in communication
with the through holes. The through hole @ force is connected at its end to the square hole in the
spool, and the inner end of the valuable (c) is tightly inserted in the hole. As shown in FIGS. 3 and
4, Valuables are indicated by an arrow mark () to switch the sound connection between the
through hole and the bell (2) or (Esefram). It can be turned up and down along with it. As a
result, Valuables not only serve to form an air passage for transmitting acoustic waves to both
ears, but also serve as a bar for rotating the spool 4 and a bar. Thus, the auscultator can use only
one hand to not only switch the position of the valve spool in the manner already described but
also to hold the microphone 0 on the patient. Releasing the sleeves to the two illustrated
positions so that the pulp spools 4 do not move unnecessarily. i19! Means are provided. In
this embodiment, the means comprises as a component a pair of lateral locking grooves formed
around the pulp spool 4. A pin or a bar is fitted in the opening in the body member tt eta, and
when the locking groove comes to the position of the pin 3 in the space (zo3) formed by the body
member blocking and seasoning. It is inserted into the retaining ring by the disposed screw
(101). Therefore, when the metal tube qI9 is levered, the pin acts against the pressing force of
the slip (101), but is pushed downward by the flange formed between the retaining groove and
the-. It is done. When the movement of the metal tube (c) continues, the busy is inserted into the
newly facing locking groove (d).
Therefore, the above-mentioned snaps and pins ensure that the spool (P) is oscillating until a
sufficient force is applied to the pipe (C). It has an appropriate shape conforming to 19-. For
example, as shown in FIG. 3 and FIG. 4, ten-grooves (xlt), concave grooves (113), etc. are formed
in the 'Ig tie member. This rounding, l die member (good), knu is properly engaged and fixed by a
suitable means such as a bolt (11, etc.) which penetrates the body-men's type (ii) and is screwed
into the 1 g tee member φ force. it can. In other words, after the bolt (1 × 5) is set up, the
diaphragm and the link 4 are assembled. In particular, as shown in FIG. 4, the bell-shaped axis −
intersects with the central axis of the diaphragm and the microphone (1 o 9) at an acute angle.
The angle between these axes is preferably about 30 but may be as large as 70 °, as small as <1
& 20 °. In any case, in the illustrated embodiment, the axes -20- and (109) intersect at the side
of the tire fram work opposite to the volume (b). However, in order to change the angle of the
axis so as to be coaxial with the axis (1 o 9), the depth of the bell-must be reduced or the
thickness of the microphone 07 (111) must be increased. Similarly, when displacing the axis in
the counterclockwise direction about the point of intersection of the axes, make the radius of the
periphery of the bell-like part considerably smaller, or increase the thickness of the microphone
0 front Must. In other words, by properly selecting the acute angle between the two axes, the
microphone itself can be made to a minimum practical thickness and the maximum depth of a
practical bell-like part. Also, although the opening @ sword communicates with the switching
pulp from the bell, it does not have to be on the bottom of the bell or on the axial ring. The
reason is that even if the positions of the six openings are offset from the axis, the sound is not
adversely affected. Furthermore, as is apparent from a comparison of FIG. 3 and FIG. 4, the
apologist can operate the microphone extremely easily because the pulp spool and the various
listening holes or openings are configured in a specific relationship. When, for example, the bell
is applied to the body of the auscultator as shown in FIG. 3, the sound QJ is in the down position,
so that in this case it is easy for the auscultator to manipulate and hold the microphone.
Similarly, when the scrap earflamm is held against the patient's body as shown in FIG. 4, the
sound is on the raised line, which allows the microphone to be easily held against the patient.
Since the application of the present invention reduces the thickness and bulk of the microphone,
the auscultator should have the microphone 07 without giving the patient any discomfort in a
narrow space under or in the patient's shirt. Is extremely easy. Furthermore, the auscultator does
not bother the patient; C. Also, it is usually quite easy to invert the microphone 0, without having
to take the microphone 07 out of the patient's clothes, thus simplifying the auscultation and
examining Make it possible to be quick. Although the preferred embodiments of the present
invention have been described above, it is needless to say that the present invention is not
limited only to this K, and various modifications may be adopted without departing from the
scope of the present invention. Variations of the will be apparent to those skilled in the art
without being shown and described.
