Abstract
The utility model discloses a patient monitoring system used for solving the problem that only interval monitoring is provided by an existing monitoring method. The patient monitoring system comprises at least one nanometer friction sensor, a signal processor, a displayer and a communication device, wherein the signal processor is connected with the nanometer friction sensor, and the displayer and the communication device are respectively connected with the signal processor. The nanometer friction sensor comprises a first electrode, a first high-molecular polymer insulating layer and a second electrode all of which are sequentially overlapped, wherein the first electrode and the second electrode are signal output electrodes of the nanometer friction sensor. The nanometer friction sensor is used for monitoring the moving situation of a patient; when the patient turns over or coughs or trembles or does other motions, the first electrode and the second electrode sense charges of different polarity, and the potential difference is produced between the first electrode and the second electrode so that an electrical signal can be produced; the moving situation of the patient can be obtained by monitoring the electrical signal.
Description
Technical field
This utility model relates to electronic information technical field, particularly a kind of monitoring system.
Background technology
At present, for the system of patient care, generally can't provide convenience, continue, constantly guard round the clock.For example, in the general duty nursing ward of a hospital, usually by one group of nurse with the interval of the 3 or 4 hours patient that patrols one by one, in order to obtain crucial sign such as respiratory frequency and heart beating, thereby reach the monitoring purpose.But this intermittent monitoring can cause disappearance or the delay diagnosed, causes the disadvantageous consequence to patient, and this especially can occur in the state of an illness may fast-changing very weak patient.
For example, for the patient with severe symptoms is guarded, active situation such as need to reviving to it, move, drop on bed is understood timely and effectively, and then implement corresponding treatment or nurse, with safety and the treatment timely subsequently of guaranteeing to greatest extent patient, this is a very important job to patient, family members and hospital.Because patient with severe symptoms's change of illness state ratio is very fast, take above-mentioned intermittent mode of monitoring more easily to miss best rescue opportunity, thereby cause the consequence that can't retrieve.
As can be seen here, mode of monitoring of the prior art can only provide intermittent monitoring, can't provide continuously and constantly monitoring round the clock patient.
The utility model content
This utility model provides a kind of monitoring system, in order to solve mode of monitoring of the prior art, can only provide intermittent monitoring, can't provide continuously and the continuous problem of monitoring round the clock patient.
A kind of monitoring system, comprise: at least one nano friction sensor, the signal processor that is connected with described at least one nano friction sensor, and the display and the communication equipment that with described signal processor, are connected respectively, wherein, described nano friction sensor comprises: the first electrode that is cascading, the first high molecular polymer insulating barrier, and the second electrode; Wherein, described the first electrode and the second electrode are the signal output electrode of nano friction sensor.
In this utility model embodiment, by the nano friction sensor, monitor patient's action situation, patient, make while the action such as standing up, coughing or shaking, due to the friction between the first high molecular polymer insulating barrier and the second electrode, on the first electrode and the second electrode, induce respectively the electric charge of the opposite sex, cause producing electric potential difference between the first electrode and the second electrode, thereby produce voltage or current signal, by signal processor, monitor the action situation that this voltage or current signal can obtain patient.Wherein, display can be used for showing monitoring result, and communication equipment can be used for notifying relevant medical personnel and family members, and thus, this monitoring system can provide continuously and constantly monitoring round the clock for patient.
