Field of the Invention The present invention relates to an ultrasonic Doppler fetal heart rate detector (hereinafter simply referred to as "Doppler apparatus"), and more particularly, to capture a target fetal heart even for those who have little or no experience using the apparatus. In order to make it easier for the user to determine whether the signal source (fetal heart) in the observation area (hereinafter abbreviated as the target area) is on the left or right side of the front of the probe held in the user's hand, The present invention relates to a stereophonic sound that utilizes the ability to discriminate the ear.

This is not the discrimination of spatial positional relationships.

った。As described above, since the conventional Doppler apparatus cannot discriminate the spatial positional relationship, the operation of capturing the target fetal heart in the front, that is, at the highest sensitivity, perturbs the beam formed by the probe in the left, right, up, and down directions. It involves trial and error, while listening to the ears and judging which should be moved left, right, up or down in relation to the increase or decrease in volume. For this reason, it has been a certain difficulty to let a person who has no or little experience using it, for example, a patient (pregnant woman) or her family, do this.

る。According to the present invention, in order to facilitate the above operation, a signal source (fetal heart) in a region to be observed (hereinafter abbreviated as a target region) has a probe held in a hand of a user. Using the hearing discrimination ability of both ears to make a stereophonic listening to the left or right side of the front of the child, and to capture this in front, it is necessary to move or tilt the probe to either side Was made to be able to judge intuitively. That is, according to the present invention, two sensitive areas are provided adjacent to the left and right in a target area, and a Doppler signal coming from a right-hand object viewed from a user of the two sensitive areas is received by a right ear and a left-hand object.

により送波音場を共有する。1 and 2 schematically show a target area, a probe, the arrangement of transducers inside the probe, and the relationship among a transmitter, a receiver, headphones and the like in one preferred embodiment of the present invention. It is the thing shown in. In this, as shown in FIG.
On the bottom surface of the probe housing (1), that is, the contact surface (2) in contact with the patient's body surface, three transducers (R) are provided behind the member.
1, T, R2) are arranged side by side. The member of the contact surface (2) forms a flat plastic thin plate as commonly used in this type of device, and these three vibrators are adhered to the back thereof at appropriate intervals. In this case, as an example, the central object (T) is a rectangular plate for transmitting a wave, and the objects (R1, R2) on both sides are semicircular for receiving a wave, each of which is a thin plate of a piezoelectric ceramic such as PZT. And has a thickness (about 1 mm) corresponding to the used frequency (for example, 2 MHz). These are respectively coupled to a transmitter (carrier generator) (3) and receivers (4a, 4b) as shown in FIG. 2, and outputs of the respective receivers are respectively coupled to left and right inputs of headphones (6). I have. Here, these transmitter / receiver and transmitter / receiver constitute a known CW Doppler system, and the transmission sound field is shared by the configuration of one transmitter and two receivers.

性質は至近距離から遠距離まで本質的に変らない。In such a configuration, focusing on the ultrasonic sound field in the target region, the shared transmitting beam formed by the transmitting oscillator T does not have a very large width of the oscillator. It becomes slightly wider in the width direction (shorter axis direction). On the other hand, on the receiving side, the width of the receiving oscillator is significantly wider than that of the transmitting oscillator, so that the width of the receiving beam in the direction is narrower than the transmitting beam. A cross section where the transmit and receive beams for each of the two receivers overlap,
That is, the sensitive area as the Doppler system is represented by Xa,
As shown by Xb, the probe is always adjacent to each other, and a boundary between the two probes, that is, a position where both sensitivities are equal, is located on the central axis of the probe. This property does not essentially change from a short distance to a long distance.

One can immediately understand which of the ears can hear the louder, and which one can move or tilt the probe to catch it on the front or center axis.

In other words, it is obvious that the user must hold the probe upside down or up and down in the correct direction in order for such a method to be able to achieve its purpose skillfully. It suffices to engrave and display the top and bottom, especially a mark or arrow indicating the top, but in FIG. 3, as a particularly preferred embodiment, if a person holds it by hand, it naturally goes in a specific direction. This shows the use of a probe housing with a unique asymmetric outer shape that has a high probability of being naturally held in the correct direction because it has only a specific shape or is extremely difficult to hold in other directions.

Is set so that its cross section corresponds to each side of an isosceles or inequilateral triangle, and in particular, the surface S to be contacted by the index finger
Keep 2 the smallest. In this case, a person generally does not hold a finger other than the index finger against the narrowest surface S2. Therefore, it is indispensable that the direction in which the probe is held is always set up with the direction of the index finger upward, that is, the farthest point when viewed from the user. This happens regardless of whether you are left-handed or right-handed.

Asymmetry here has such a meaning. Here, the left and right directions refer to the width direction or the short axis direction, that is, the direction in which the vibrators are arranged, with reference to FIG.

The housing (1) of the probe accommodates all necessary electronic devices and power supply means, and no wires are allowed to enter and leave the housing from outside, and the acquired right and left ears are obtained. For example, the two-channel audio signal is converted into a high-frequency signal modulated according to the signal standard of FM stereo broadcasting. This high-frequency signal is electrostatically coupled to both the user's hand and the patient's body so as to be used as a transmitting antenna, and is transmitted wirelessly. In this case, the receiving means is a commercially available FM (not shown).
It can be satisfied with a receiver for stereo broadcast reception.

The output is between one coupling electrode A1 and another coupling electrode A2, which is also arranged in contact or non-contact in the vicinity of the contact surface (2) in contact with the patient's body. The figure shows a case where the housing (1) of the probe is entirely made up of a sealed structure with an insulating plastic material.
In A2, the high-frequency signal is transmitted to the user (1
It is transmitted between 1) and the patient (10). With such a configuration, the high-frequency signal is effectively radiated to the space with higher radiation efficiency by both the patient (10) and the user (11) as external additional antenna means, and is a commercially available listening means (not shown). The signal is transmitted to a receiver for receiving FM stereo broadcast.
In practice, when either the patient or the user is absent, the level of high frequency signal emission can be greatly reduced, and when not used in the situation shown, the high frequency signal emission is substantially reduced. You can make it rarely done.

However, if the device can be operated only for a few minutes at most, one continuous use is limited to that time, so that it is possible to prevent the patient from being excessively irradiated with ultrasonic waves. Can be done. This is one of the effective means for ensuring ultrasonic safety when the patient or his / her family uses the apparatus. In this case, the secondary battery (25)
It is preferable to use an electric double-layer storage device instead of a so-called secondary battery such as a nickel-cadmium battery. That is, in the embodiment in this case, in the probe which is the present device having the sealed-off structure, the power supply means in the housing (1) is the only one which is an electric double-layer storage device used in such a manner. And the discharge completion time of the electric double-layered storage device by the operation of the present device is set to be about 5 minutes or less, which is generally considered to cause no ultrasonic trouble.
