Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited thereto.
Examples
Referring to fig. 1-2, the present embodiment provides a wireless uterine contraction pressure monitoring probe, which is characterized by comprising a housing, and a pressure sensing assembly 103 and a circuit board assembly 104 inside the housing, wherein the housing is divided into an upper shell 101 and a lower shell 102, and the lower shell 101 is provided with a soft colloid 105;
the pressure sensing assembly 103 comprises a bearing body 201, a load cell 202 and an elastic body 203 between the bearing body 201 and the load cell 202;
the weighing sensor 202 is of a plate type and comprises a fixing area G and a strain area B, the fixing area G is fixed on the lower shell 102, one end of the elastic body 203 is connected to the strain area B, the other end of the elastic body is connected to the bearing body 201, and the other end of the bearing body 201 is connected to the inner surface of the lower shell soft rubber body 105.
It should be noted that the obstetrical department of the user of the wireless uterine contraction pressure monitoring probe provided by the embodiment measures uterine contraction pressure. In normal uterine contraction pressure measurement, the effective stress interval of the weighing sensor is generally about 10 newtons, namely the difference between the stress of the weighing sensor without uterine contraction and the stress of the weighing sensor with the maximum uterine contraction is about 10 newtons. However, in a special situation, such as when the probe falls on the ground, since the soft rubber body 105 on the surface of the lower shell slightly protrudes from the outer surface of the lower shell, when the soft rubber body 105 directly contacts the ground, the inward compression displacement of the soft rubber body is too large (exceeding the maximum displacement amount in normal use), and the stress of the weighing sensor may exceed the maximum measuring range of the weighing sensor, so that the weighing sensor is damaged. In this embodiment, when the soft gel 105 on the lower shell surface compresses inwardly, the elastomer compresses inwardly, which may buffer this "flash pressure".
It should be noted that, in the uterine contraction pressure measurement, a linear interval of at least 10 newtons needs to be ensured, and at this time, the soft colloid 105 on the surface of the lower shell is required to be not displaced, that is, the elastomer is required to be not or only minimally deformed, so that the measurement is accurate. When the pressure exceeds the pressure, the soft rubber body 105 compresses inwards, and the elastic body compresses inwards, so that the overflow pressure can be buffered.
In this embodiment, the load cell is a plate type, the peripheral G area is a fixing area, and is fixed to the corresponding screw hole of the lower case 102 by 4 bolts, and the central B area is a strain area. In the prior art, the part is generally applied to kitchen electronic scales and is widely used. The embodiment applies the wireless uterine contraction pressure monitoring probe to uterine contraction pressure monitoring, and can reduce the overall cost of the wireless uterine contraction pressure probe and the weight of the probe.
In this embodiment, the circuit board assembly 104 includes a battery, a power management circuit, a pressure data collecting and processing circuit, a storage module, a wireless communication module, and the like, and is mainly responsible for collecting pressure changes sensed by the weighing sensor, calculating a uterine contraction pressure value, and finally transmitting the uterine contraction pressure value to the fetal monitor host through the wireless communication module.

after installation, the distance d between the cover part 204 and the fixing area G is not more than the deformation amount of the elastic body 203 when the elastic body bears Nmax, and Nmax is the overload pressure of the weighing sensor.
In this embodiment, in order to further effectively prevent the load cell from being damaged due to overload, the bearing body 201 is provided with a cover portion 204 and a column portion 205, the strain region B and the elastic body 203 are provided with through holes, and the column portion 205 can penetrate through the through holes. The working principle is as follows: when external pressure is applied, the soft colloid 105 is compressed inwards, the elastic body 203 is compressed along with the soft colloid, when the rigid body 204 reaches the fixed area G, the increased external pressure is not applied to the strain area B, and the fixed area G bears the pressure, so that the purpose of preventing the weighing sensor from being damaged due to overload is achieved. Meanwhile, the distance d between the cover body part 204 and the fixing area G is not more than the deformation amount of the elastic body when the elastic body bears Nmax, and Nmax is the overload pressure of the weighing sensor. The elastic body 203 can be selected by referring to the principle description of the elastic part in paragraphs [0071] to [0078] of the invention patent of china with application number 201410195486.9, a protection device for uterine pressure sensor and method thereof.
