Digital pressure sensor with rubber cover

#This application claims the benefit of the filing date under 35 U.S.C. § 119(a)-(d) of Chinese Patent Application No. 201921851206.X, filed on Oct. 31, 2019.

#The present invention relates to a sensor and, more particularly, to a digital pressure sensor.

#Medical pressure sensors are widely used in surgery because of its real-time testing of variation in a patient's blood pressure. The medical pressure sensor is to puncture the needle tube into the blood vessel of the object to be detected with the outer end of the needle tube being directly connected to the pressure sensor. Since fluid can transfer pressure, the pressure in the blood vessel is transferred to the external pressure sensor through the liquid in the catheter so as to obtain the dynamic waveform of real-time pressure variations in the blood vessel.

#The invention will now be described by way of example with reference to the accompanying Figures, of which:

#FIG. 1 is a perspective view of a digital pressure sensor according to an embodiment;

#FIG. 2 is an exploded perspective view of the digital pressure sensor of FIG. 1;

#In order to make the technical problem to be solved by the present disclosure, technical solution, and advantageous effect clearer, the present disclosure is elaborated with reference to the drawings and embodiments as follows. It should be understood that the embodiments described here are only used to explain the present disclosure and do not limit the present disclosure. Further, the drawings in the following description are only some of the embodiments of the present disclosure; for those skilled in the art, it does not require any creative labor to obtain other drawings based on these drawings.

#It should be noted that an element may be directly on another element or indirectly on the another element when referred to as being “fixed to” or “provided on” another element. An element may be directly connected to another element or indirectly connected to the another element when referred to as being “connected to” another element. In the description of the present disclosure, it should be noted that, unless otherwise clearly provided and defined, the terms “mounting”, “connect” and “connection” should be understood in a broad sense. For example, it may be fixed connection or detachable connection, or integrated connection; it may be mechanical connection or electrical connection; it may be direct connection, or indirect connection through an intermediate medium, and it may be the internal communication between two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in the present disclosure according to specific situations.

#A digital pressure sensor 100 according to an embodiment is shown in FIGS. 1 and 2. The digital pressure sensor 100 includes a pressure sensing structure 1, a signal processing chip 2, a rubber cover 3, and a substrate 4. The pressure sensing structure 1 is used to detect the pressure of the object to be measured, such as detecting the blood pressure of the object to be measured, and the pressure of the effusion inside a female patient's uterus, etc. The signal processing chip 2 is used to receive the sensing signal of the pressure sensing structure 1. The pressure sensing structure 1 and the signal processing chip 2 are mounted on the substrate 4 respectively, and the substrate 4 and the rubber cover 3 are connected to each other.
