Technical Field

The invention relates to the field of mother and infant monitoring, in particular to an integrated dual-purpose probe capable of simultaneously measuring fetal heart rate and uterine contraction pressure.

Background

Maternal and infant monitoring requires the study of fetal heart rate, uterine contraction and fetal movement laws. The traditional fetal monitoring device generally collects corresponding data through three devices, namely a fetal heart ultrasonic probe (used for obtaining a fetal heart rate), a uterine pressure probe (used for obtaining a uterine contraction law) and a fetal movement button device (used for obtaining a fetal movement law). However, the three devices respectively collect data, which increases the cost of the monitoring device and complicates the operation of the monitoring process.

With the increasing development and maturity of perinatal monitoring technology, an automatic fetal movement algorithm is available at present, and only uterine contraction pressure needs to be collected, so that a corresponding fetal movement rule can be obtained by using the algorithm, and a fetal movement button device is replaced. The existing fetal monitoring equipment can be further simplified, and a device for monitoring the fetal heart rate, fetal movement and uterine contraction simultaneously is designed. To monitor fetal heart rate, fetal movement and uterine contraction pressure "simultaneously", a device is needed that can acquire signals of fetal heart rate and uterine contraction pressure simultaneously.

The existing design is that a measuring ultrasonic sensor and a uterine contraction pressure sensor are fixed on the same surface of a probe; or under the condition of ensuring that the acquisition of the fetal heart rate and the uterine contraction pressure do not influence each other, the contact of the pressure sensor is arranged on the ultrasonic acquisition surface.

However, adding a pressure contact on the ultrasound acquisition face can present the following problems:

first, the ultrasound propagation medium is not uniform and is liable to generate a large amount of radiation, which requires that the ultrasound acquisition surface and the skin filler couplant have to be well adhered, and the pressure contact and the skin filler couplant have the same requirements, which inevitably results in strong sense of squeezing at the contact position.

Secondly, if the person skilled in the art uses softer materials to reduce the uncomfortable feeling of the pressure contact, the materials are not easy to clean after contacting the couplant, and bacteria are easy to breed after long-term use.

Therefore, under the condition of ensuring that data acquisition is not influenced mutually, how to better combine the ultrasonic sensor and the uterine pressure sensor into a whole is a technical problem to be solved urgently in the field. .

In order to solve the technical problems, the invention adopts the following technical scheme:

dual-purpose probe of integration, including the probe body, the probe body is equipped with the tow sides, and wherein openly sets up child heart rate monitoring devices, and the reverse side sets up palace pressure monitoring devices.

Furthermore, the pressure action mechanism also comprises a pressing piece matched with the hard force application piece, and the pressing piece is detachably connected with the probe body.

Further, the hard force application piece is arranged on the tightening piece.

Furthermore, two sides of the probe body are symmetrically provided with connecting mechanisms for assisting tensioning of the tensioning piece.

Furthermore, the probe body is provided with an accommodating part for detachably connecting the pressure sensor, and the accommodating part is provided with a through hole for protruding a contact of the pressure sensor.

Furthermore, a reciprocating mechanism is arranged on the probe body in the direction of movement of the pressure sensor contact after being pressed.

1. the integrated dual-purpose probe can finish data acquisition of fetal heart rate, uterine contraction and fetal movement.

2. The integrated dual-purpose probe is convenient to use and reduces the equipment cost because the pressure sensor is used as a replaceable accessory.

3. The pressure sensor with the contact is not in direct contact with the pregnant woman, so that potential safety hazards caused by temperature rise and electronic radiation can be avoided.
