Description

Auscultation device for pregnant woman

Technical Field

The utility model relates to an obstetrical medical equipment technical field especially relates to an auscultation device for pregnant woman.

Background

Auscultation of pregnant women generally refers to fetal heart sound auscultation, which is an important means for guaranteeing the safety of pregnant women and fetuses and realizing prenatal and postnatal care. The fetal heart is an important index of vital signs of a fetus, and the fetal heart is monitored daily during pregnancy so that the health condition of the fetus can be judged, and fetal abnormality can be discovered and treated as soon as possible, so that the health risk and the death rate of the fetus are effectively reduced. Therefore, adequate daily monitoring of the fetal heart during pregnancy, especially late in pregnancy, is of great clinical importance to ensure the healthy development of the fetus. Fetal heart detection includes detection of fetal heart sounds. Fetal heart sound is the sound of the heart beat of the fetus. The pregnant woman can hear the double-tone fetal heart sound like a clock 'ticking' sound after 18-20 weeks of gestation. The fetal heart is an important organ for providing oxygen and nutrition to the fetal body, and its activity is governed not only by the body fluids such as blood movement and hormones, but also by the central nerve, the brain, all of which are reflected in the rhythm of fetal heart sounds. Therefore, the fetal heart sound collection and monitoring has very important significance for doctors and pregnant women to know the growth and development conditions of the fetus in time, discover hidden diseases possibly existing in the fetus in time and take corresponding measures to protect the safety of the mother and the baby in time.

Currently, a fetal heart stethoscope is usually adopted for detecting fetal heart sounds, and a professional doctor can find out the orientation of a fetus by probing different positions of the abdomen of a pregnant woman through the stethoscope, hear the fetal heart sounds and judge the state of the fetus, for example, when the fetal heart sounds are close to the upper part of the back of the fetus on the abdominal wall of the pregnant woman, the heard fetal heart sounds are clearest; when the fetus is exposed firstly, fetal heart sounds are positioned at the left/right lower part of the navel; when the fetus is presented with the arm first, the fetal heart sound is on the left/right upper part of the navel; when the fetus is exposed from the shoulder, the fetal heart sound is below the navel. Fetal heart sounds are sounds of fetal heart beats and have important clinical significance, whether a fetus in a uterine cavity is normal or not can be judged through the fetal heart sounds, the fetal heart sounds beat for about 120-160 times per minute, if the fetal heart sounds are lower than 120 times per minute or higher than 160 times per minute, the phenomenon that the fetus is lack of oxygen in the uterine cavity is caused, and the fetus should be subjected to oxygen inhalation treatment in time in a hospital.

However, for the pregnant women in the ordinary families, the traditional fetal heart stethoscope has small sound and large external interference, so that the pregnant women are difficult to judge the fetal position through the fetal heart stethoscope and clearly hear fetal heart sound signals of the fetus through the fetal heart stethoscope, and can not judge whether the fetal heart sound is normal or not. Meanwhile, the stethoscope capable of monitoring weak fetal heart sounds in the prior art is usually in wired connection, does not have the characteristic of portability, and cannot monitor the fetal heart sounds anytime and anywhere.

The prior art, for example, patent document with publication number CN214342392U, discloses an improved wireless bluetooth stethoscope, which belongs to the medical technology field. The box mainly comprises a box body, a box cover and a fixing band, wherein the box cover is covered on the box body, and the fixing band is connected on the box body; the stethoscope box comprises a box body, a box body and a sound pick-up, wherein a voice broadcast device is arranged on the box body, a stethoscope head is movably embedded in the box body, a charging pole piece is arranged on the side surface of the stethoscope head, a first power supply is arranged in the box body, an electrode end of the first power supply is in contact with the charging pole piece of the stethoscope head to charge the stethoscope head, the sound pick-up is arranged on the bottom surface of the stethoscope head, a Bluetooth transmitter, a first controller and a second power supply are arranged in the stethoscope head, and a switch for starting the Bluetooth transmitter is arranged on the stethoscope head; the box body is internally provided with a Bluetooth receiver and a second controller, and the box cover is provided with a display screen. The wireless bluetooth stethoscope body type of this improvement is small and exquisite, and portable has set up voice broadcast ware and display screen, also practices thrift the time of a plurality of doctors 'auscultations, can carry out the auscultation simultaneously by a plurality of doctors, and the doctor of being convenient for discusses patient's the state of an illness. However, the stethoscope cannot accurately auscultate fetal heart sounds, and cannot monitor fetal heart sounds at different positions through the self-structure of the stethoscope. Meanwhile, the stethoscope does not have the noise reduction function, and the monitoring of fetal heart sounds is interfered by noise such as bowel sounds of pregnant women, abdominal bleeding sounds and the like.

Patent document No. CN104586425A discloses a wearable fetal heart sound monitor based on a multi-angle stethoscope array, which includes a cavity-type abdominal belt, a sound monitoring array fixed on the back of the cavity-type abdominal belt for monitoring fetal heart sounds, a signal processing circuit disposed in the inner cavity of the cavity-type abdominal belt, and a handheld mobile terminal located outside the cavity-type abdominal belt and wirelessly connected with the signal processing circuit. The fetal heart sound monitoring device is ingenious in design, simple in structure, safe and convenient to operate, capable of easily achieving collection and display of fetal heart sounds in a pregnant woman, and high in practical value. However, the invention cannot monitor the uterine contraction signal of the pregnant woman and the heart rate change of the pregnant woman at the same time.

Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor studied a lot of documents and patents when making the present invention, but the space did not list all details and contents in detail, however, this is by no means the present invention does not possess these prior art features, but on the contrary the present invention has possessed all features of the prior art, and the applicant reserves the right to increase the related prior art in the background art.
