Abstract

The utility model provides a micro sensor intracranial pressure monitor, which relates to intracranial drainage and monitor devices techniques in the medical monitoring field. The technique comprises a detector head and a pressure display circuit. The detector head consists of a drainage tube and a micro pressure sensor which is arranged on the cavity sidewall of the drainage tube and connected with the pressure display unit by lead. The pressure signals leaded out by lead are sent to the display unit to display after the amplifying of an operational amplifier. The utility model is simple in structure, small in open-skull aperture, precise in detecting, and convenient in use.

Description

The microsensor ICP (monitor intracranial pressure monitor)
Technical field
This utility model relates to the medical monitoring apparatus field, particularly the ICP (monitor intracranial pressure monitor) correlation technique.
Background technology
The monitoring of intracranial pressure is a clinical significant observation index, can be directly connected to patient's personal safety, medical personnel is grasped the state of an illness and treatment directly foundation is being provided.At present to intracranial pressure the existing different monitoring equipment of monitoring, as the intrinsic pressure monitor of the ventricles of the brain, the cerebrospinal pressure monitor, the patent No. is: the non-invasive intracrenial pressure monitor of " 852303288 " etc.These custodial care facilities can be divided into two classes, one class is out the cranium monitoring, another kind of is to open or not the cranium monitoring, for the equipment of opening the cranium monitoring, the probe size that enters intracranial at present is all very big, this just needs the bigger cranium aperture of opening, and easily causes patient's brain injury and infection and postpones patient's healing stage.For the monitoring equipment of not opening cranium, use inconvenient operation comparatively speaking, and certainty of measurement is not high.
Technology contents
This utility model purpose is that design is a kind of simple in structure, and it is little to open the cranium aperture, measuring accuracy height, microsensor ICP (monitor intracranial pressure monitor) easy to use.
The realization of this utility model technology can be achieved through the following technical solutions:
The microsensor ICP (monitor intracranial pressure monitor), comprise detecting head and pressure display circuit part, described probe comprises drainage tube and micro pressure sensor, drainage tube is provided with cavity and lead channels, the lead that is respectively equipped with micro pressure sensor in cavity and the lead channels and joins with pressure display circuit part input.Joined by the input of micro pressure sensor by lead and operational amplifier D1 in the described pressure display circuit part, the input of the outfan of operational amplifier and display unit D2 joins.
This utility model technological progress is, mozzle and microsensor are combined, behind craniocerebral operation, put into this utility model detecting head in the surgical wound surface district, promptly can drain the pressure of encephalic operation wound surface can be derived again, be convenient to medical personnel's monitoring, the cranial cavity wound surface is little, be difficult for causing infection, reduce patient's misery.
