Abstract

The invention relates to a programmer for ventilators, which are controllable via a computing and control device as a function of data of predetermined types of ventilation and ventilation parameters and control by inhalation and exhalation control signals. Known ventilators already have control devices that work preprogrammed and update a logical program flow. Taking advantage of these solutions, a control center for physiologically required program controls is to be developed, which also makes the issued function commands visible. This is achieved with a central control, computing and monitoring device, which is provided with a display panel and a Beruehrungstastatur.

Description

Programming device for ventilators

Field of application of the invention:

The invention relates to a programmer for ventilators, which can be controlled via a calculation and control device as a function of data of prescribed types of ventilation and ventilation parameters and control the inhalation and exhalation by means of control signals. The programming, z, B can be performed Type of ventilation to be carried out by the user on the front operating side of the ventilators or at a distance from them

Characteristic of the known technical solutions

A respiratory system is known in which gas flow to the patient is controlled by multi-device controlled solenoid w shifters (DE-OS 27 4-5 528). Thus, once adjusting devices present with which a plurality of individual predetermined threshold value signals are set and on the other signaling devices that are used to produce at least one common signal ₀ Furthermore, devices are required which compare each threshold signal with this common-varying signal, in order then again to generate a plurality of control signals " After all

are still too. Equipment required to supply these control signals to the solenoid valves »

Although the ventilation modes, the inspiratory phase and the expiratory phase as well as other feasible states are controllable with this relatively complex system solution, their program flow is only cumbersomably adjustable and influenceable by the decentrally arranged data input / output devices and not satisfactorily visible or controllable.

But there are also ventilation systems with ventilators be-r known, whose electronic controls built from integrated circuits and are provided with respiratory rate computers imd in the systematic composite compact units (DD-WP A 61 M / 235 774, DD-WP A 61 M / 24Q i ^ -O). These electronically controlled ventilators perform the functions of the many types of ventilation in an excellent manner and their compact control systems with computer measure the program but excellent, but their ease of use is not optimally designed. "This aims for a time control for electronically controlled ventilators using program selection circuits, as well to select the station memories in the television and payphone system (DD JSI PA 61 M / 245 762) This has created a requirement for programmed controllers in which a logical operation is programmed between input and output data according to their preselection It can also be used to update output data according to the result of the logical program execution.

Object of the invention:

The aim of the invention is to utilize the advantages of the aforementioned solutions for anesthesia and therapy.

Explanation of the essence of the invention:

The object of the invention is to develop a control center for physiologically required program controls, by means of the corresponding aer desired ventilation initially a standard patient designed for basic program is controlled, which can then be specified by optimizing the ventilation parameters · All issued function commands to a display visible to and digitally display all ventilation parameter changes ·

According to the invention, the Aufgäbe is solved by a central control, computing and monitoring device, which is provided with a> display panel and with a touch keyboard and connected to an input control and an output control connected to this output control · The touch keyboard is divided into several keypads of which one is provided for the preselection of the type of ventilation and its quantitative quantities and another for the successive parameters of the ventilation parameters * Furthermore, a keypad for Überwaohungsungsgrößen z, B · the breath pressure and a keypad for storing optimal ventilation programs and a Quantification of quantities according to the first keypad is also present. Further, for an optimizing, storing or deleting possibility, certain touch keys may be directly assigned to the keypads or arranged separately. The display panel consists of at least two display panels, one of which displays a display for quantitative quantities of the ventilation modes and the other display panel for the ventilation modes

Display of quantitative sequence quantities and monitoring quantities is determined.

In further. It may also be desirable to connect the central control, computing and monitoring device, which has a state detector, directly to the output controller and to equip it with a basic program which is the basis for all types of ventilation and is retained after deletion of an optimized treatment program.Preferably also the programming in alphanumeric operation can be carried out, in which case the Tasijen- and display panels are designed for such operation _e

The display fields are preferably associated with the keypads such that the keypad designated with the one display field and the keypads designated for quantitative sequence variables and monitoring parameters are associated with the other display field.
