Abstract
The invention discloses a thorax puncture instrument. The thorax puncture instrument comprises a thorax puncture tube which is used for being inserted into the thorax, a pressure sensor, a single-chip microcomputer, a solenoid valve and a display screen, wherein the pressure sensor is connected with the thorax puncture tube through a pipe and is used for inducing the interior pressure of the thorax, the single-chip microcomputer is in telecommunication connection with the pressure sensor and is used for acquiring voltage signals transmitted by the pressure sensor and processing the voltage signals into pressure signals, an inlet of the solenoid valve is connected with the thorax puncture tube through a pipe, an outlet of the solenoid valve is connected with the environment, a driving circuit is arranged in the solenoid valve and is telecommunication connection with the single-chip microcomputer, the solenoid valve is controlled to be turned on and turned off through the single-chip microcomputer, and the display screen is in telecommunication connection with the single-chip microcomputer and is used for receiving the pressure signals which are transmitted by the single-chip microcomputer and displaying the pressure signals on the screen. By the adoption of the thorax puncture instrument, manual operation can be replaced by instrument control, automatic measurement and control over the amount of discharged gas or the amount of discharged liquid are achieved, and the pressure of the thorax can be kept lower than 1.5kPa.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of thoracentesis instrument.
Background technology
Pleurocentesis is one of the diagnosis that the most often adopts of thoracic surgery and treatment technology, by bleeding, drawing liquid, thoracic cavity decompression treatment is one-sided or bilateral pneumothorax, hemothorax or hemopneumothorax.When hospital is used, be manual operation, expellant gas amount or amount of liquid will lean on medical personnel oneself judgement.This instrument, in order to solve manually-operated problem, can guarantee that pleural pressure is less than 1.5kPa.
Summary of the invention
Object of the present invention, exactly in order to address the above problem, provides a kind of thoracentesis instrument.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of thoracentesis instrument, comprise for inserting the thoracentesis pipe in thoracic cavity, and also comprise:
Pressure transducer, it is connected with thoracentesis pipe by pipeline, to respond to intrathoracic pressure;
Single-chip microcomputer, itself and pressure transducer telecom-connect, and gather the next voltage signal of pressure transducer transmission and are processed into pressure signal;
Electromagnetic valve, its import is connected with thoracentesis pipe by pipeline, and outlet and environmental communication, be provided with drive circuit in electromagnetic valve, and this drive circuit and single-chip microcomputer telecom-connect, and electromagnetic valve is by its break-make of Single-chip Controlling;
Display screen, itself and single-chip microcomputer telecom-connect, and receive the next pressure signal of single-chip microcomputer transmission and are presented on screen.
Described pressure transducer adopts 40PC001 pressure transducer.
Described pressure transducer, single-chip microcomputer, electromagnetic valve and display screen integrated installation are in an instrument container, and instrument container casing is provided with entrance sleeve and the discharge connection of pipeline, the inner connected electromagnetic valve of entrance sleeve, and outer end connects described thoracentesis pipe; Inner connected electromagnetic valve, outer end and the environmental communication of discharge connection.
Adopt thoracentesis instrument of the present invention, change manual operation into instrument and control, realized automatic measurement and control to expellant gas amount or amount of liquid, can guarantee that pleural pressure is less than 1.5kPa.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of thoracentesis instrument of the present invention.
The specific embodiment
Referring to Fig. 1, thoracentesis instrument of the present invention, comprises thoracentesis pipe 1, pressure transducer 2, single-chip microcomputer 3, electromagnetic valve 4 and display screen 5 for inserting thoracic cavity.
Pressure transducer 2 is connected with thoracentesis pipe 1 by pipeline, for responding to intrathoracic pressure and being translated into voltage signal.
Single-chip microcomputer 3 telecom-connects with pressure transducer 2, for gathering the next voltage signal of pressure transducer transmission and being processed into pressure signal.
The import of electromagnetic valve 4 is connected with thoracentesis pipe 1 by pipeline, and outlet and environmental communication, be provided with drive circuit in electromagnetic valve, and this drive circuit and single-chip microcomputer 3 telecom-connect, and electromagnetic valve is by its break-make of Single-chip Controlling.
Display screen 5 telecom-connects with single-chip microcomputer 3, receives the next pressure signal of single-chip microcomputer transmission and is presented on screen.
Pressure transducer in the present invention preferably adopts 40PC001 pressure transducer.
Pressure transducer in the present invention, single-chip microcomputer, electromagnetic valve and display screen integrated installation are in an instrument container, and instrument container casing is provided with entrance sleeve and the discharge connection of pipeline, the inner connected electromagnetic valve of entrance sleeve, and outer end connects described thoracentesis pipe; The inner connected electromagnetic valve of discharge connection, outer end is connected with gathering-device with environmental communication or by pipeline.
The operation principle of thoracentesis instrument of the present invention is, during use, just thoracentesis pipe is connected with entrance sleeve, opens instrument power source, and at this moment intrathoracic pressure just can transfer voltage signal to by pressure transducer 40PC001.This voltage signal is converted into force value and is being shown screen display by single-chip microcomputer.When input pressure is greater than 1.5kPa, single-chip microcomputer output signal is opened electromagnetic valve, and pressure is discharged by the discharge connection of electromagnetic valve, and when pressure is less than 1.5kPa, single-chip microcomputer output signal, by closed electromagnetic valve, keeps existing pressure.
