Background

The intracranial pressure monitoring provides a basis for accurately judging the change condition of intracranial pressure (ICP) caused by space occupying lesions such as intracranial tumors, intracranial wounds, intracerebral hemorrhage and the like in clinic, and can meet the requirements of diagnosis, treatment and prognosis judgment. Intracranial pressure monitoring is therefore of great clinical importance. At present, intracranial pressure monitoring is realized by adopting an intracranial pressure sensor to implant into a ventricle for monitoring pressure, a monitored pressure value is transmitted to a control system of a monitor after being connected with a coupling cable through a circuit board on the sensor, and the monitor displays the pressure value after processing so as to provide basis for judgment and treatment of doctors. Sensor and coupling cable on the present market connect and only rely on contact pin on the circuit board and coupling cable to go up the joining force of needle file and connect, sensor circuit board shell does not have special structure with coupling cable socket shell and strengthens their connection, if receive the effect of external force sensor circuit board and coupling cable junction drop easily and lead to guardianship data interrupt or contact failure, the data of monitor monitoring can not effectually provide diagnostic foundation for the doctor, consequently, need an effective structure to prevent that sensor and coupling cable from dropping by accident, the unreliability of data when avoiding intracranial pressure monitoring.

The utility model overcomes prior art's is not enough, and aim at provides an intracranial pressure sensor connector to expect can solve and place sensor and coupling cable accident and drop, avoid the unreliability of intracranial pressure monitoring time measuring data.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides a pair of technical scheme is:

an intracranial pressure sensor connector comprising: the sensor comprises a socket (1) and a sensor circuit board shell (2), wherein an elastic buckle (3) is arranged on the socket (1), and a limiting boss (10) is arranged on the buckle; the sensor circuit board shell (2) is provided with a groove (11) and is formed by tightly buckling an upper cover (5) and a lower cover (6); when the sensor circuit board shell (2) is inserted into the socket inner cavity (9), the elastic buckle (3) is opened under the action of elasticity until the elastic buckle closing boss (10) and the groove (11) are locked with each other; the elastic buckle (3) is opened when being pressed, and the sensor circuit board shell can be pulled out along the longitudinal direction.

The lug boss (10) of the elastic buckle (3) is provided with a chamfer angle less than 60 degrees.

When the front end (14) of the sensor circuit board shell is inserted into the socket (1), the inner cavity (12) of the sensor circuit board shell and the seat (13) in the socket are all sleeved together and are intersected with the inner cavity (4) of the socket.

The upper cover (5) and the lower cover (6) of the sensor circuit board shell (2) are provided with barbs (15) for locking.

The sensor circuit board shell (2) is provided with a hole (8).

An inner cavity (4) for fixing the cable is arranged in the socket (1).

The sensing circuit board shell (2) is internally provided with a step (7) for fixing the sensing circuit board.
