The pressure controller comprises an outer magnetic yoke, an inner magnetic yoke, a coil, magnets, a head pressing component and a clamp ring, wherein the inner magnetic yoke is positioned in the outer magnetic yoke; the tegular magnets are positioned between the outer magnetic yoke and the inner magnetic yoke, the magnetizing direction is radial, one magnetizes to the N pole and the other magnetizes to the S pole, and a plurality of magnets are uniformly distributed in the inner chamber of the external magnetic yoke; a radial guide groove is formed on the inner magnetic yoke, one end of the coil is positioned in the guide groove, and the head pressing component is arranged at the other end of the coil; the clamp ring is positioned at the bottom of the outer magnetic yoke; the outer magnetic yoke is provided with screw threads and connected with the gland of the expiratory valve; and a lead wire of the coil is connected with a microcomputer controlled circuit. In the utility model, as the on-off and the magnitude of electric current are controlled by a microcomputer, the end expiratory pressure of a patient can be accurately controlled.
Description
Technical field
This utility model relates to a kind of microcomputer control outlet valve, a kind of device that can step-less adjustment end-tidal pressure, and majority is applied to belong to armarium manufacturing technology field on anesthetic machine, the gentle galvanic electricity control of the electric electricing breathing machine respirator.
Background technology
Respirator is mainly used in treatment respiratory failure patient clinically, and anesthetic machine is mainly used in the patient that need do the general anesthesia operation, and in operation and therapeutic process, the pressure of accurately regulating patient's end-tidal according to patient's the state of an illness is significant to patient's treatment.Present technology is most uses mechanical types control, regulates by the pressure of regulating spring, and shortcoming is that control accuracy is low and can not feed back and carry out closed loop control.
The utility model content
In order to overcome the defective of prior mechanical outlet valve, this utility model provides a kind of microcomputer control outlet valve, can overcome this defective effectively.
Scheme of the present utility model is as follows:
A kind of microcomputer control outlet valve, described outlet valve comprises valve body, diaphragm, tabletting, gland, it is characterized in that: also comprise pressure controller, described pressure controller comprises outer yoke, inner yoke, coil, Magnet, pressure head and collar, and described inner yoke is positioned at outer yoke, and described Magnet is between outer yoke and inner yoke, be shaped as a watt shape, inner yoke is provided with the radially-directed groove, and described coil one end is positioned at described gathering sill, and the other end is provided with pressure head; Collar is positioned at the outer yoke bottom; The gland that outer yoke is provided with screw thread and outlet valve links to each other.
Described Magnet magnetizing direction is a radial magnetizing, one to the N utmost point one to the S utmost point, some blocks of Magnet are uniformly distributed in the outer yoke inner chamber.
The lead of described coil connects microcomputer control circuit, by the break-make of microcomputer control electrical current and the size of electric current.
When the patient was air-breathing, coil was connected certain electric current, and coil produces the dynamic head of trying hard to recommend upwards and seals diaphragm in magnetic field, make gas enter patient pulmonary; When the patient exhales, turn-off current, coil is because deadweight is fallen, and diaphragm is opened, thus the patient can exhale smoothly.When the patient exhales, can also be according to patient's the state of an illness, by the current value of microprocessor control coil, thereby control the pressure of patient's end-tidal accurately.

The specific embodiment
Among Fig. 1, the microcomputer control outlet valve that this utility model provides comprises valve body 1, diaphragm 2, tabletting 3, gland 4, establishes air inlet 5, gas outlet 6 on the valve body 1, and gas enters valve body 1 by air inlet 5, is discharged by gas outlet 6 through the passage of diaphragm 2 tops.Microcomputer control outlet valve also comprises pressure controller, pressure controller comprises outer yoke 7, inner yoke 8, coil 9, Magnet 10, pressure head 11 and collar 12, wherein inner yoke 8 is positioned at outer yoke 7, Magnet 10 is between outer yoke 7 and inner yoke 8, Magnet 10 is shaped as a watt shape, magnetizing direction is a radial magnetizing, one to the N utmost point one to the S utmost point, some blocks of Magnet are uniformly distributed in the outer yoke inner chamber.Inner yoke 8 is provided with radially-directed groove 13, and described coil 9 lower ends are positioned at described gathering sill 13, and described pressure head 11 is positioned at coil 9 upper ends; Gathering sill 13 on the inner yoke 8 makes coil 9 to slide up and down and can not rotate.Collar 12 is positioned at outer yoke 7 bottoms; The gland 4 that outer yoke 7 tops are provided with screw thread and outlet valve links to each other.
The structure of clearer demonstration pressure controller shown in Figure 2, it comprises outer yoke 7, inner yoke 8, coil 9, Magnet 10, pressure head 11 and collar 12, described inner yoke 8 is positioned at outer yoke 7, described Magnet 10 is between outer yoke and inner yoke, be shaped as a watt shape, inner yoke is provided with radially-directed groove 13, and described coil 9 lower ends are positioned at described gathering sill 13, and pressure head 11 is positioned at coil 9 upper ends; Collar 12 is positioned at the outer yoke bottom, is used for fixing inner yoke; Coil 9 is connected with external power source by lead 14.Coil 9 is wound on the bobbin, and when feeding DC current in the coil, bobbin produces thrust upwards.The gland that outer yoke top is provided with screw thread and outlet valve links to each other.
Shown in Figure 3, the respirator delivery outlet links to each other with microcomputer control outlet valve of the present utility model and patient by pipeline and three-way body, gas enters valve body from air inlet 5, and when patient inhales, coil 9 is connected certain electric current, coil produces power upwards in magnetic field, bobbin moves upward along gathering sill 13, and the pressure head 11 of upper end is roof pressure tabletting 3 upwards, makes diaphragm 2 sealing outlet passageways, gas can't be discharged by gas outlet 6, makes gas enter patient pulmonary; When patient exhales, turn-off current, bobbin is because deadweight is fallen, and diaphragm 2 is opened, and patient expired gas is discharged by the gas outlet, thereby can exhale smoothly.This utility model is by the break-make of microcomputer control coil electrical current and the size of electric current.When patient exhales, can also be according to patient's the state of an illness, by the current value in the microprocessor control coil, thrust that can the control coil frame is regulated the degree of closure of outlet passageway, thereby can accurately be controlled patient's end-tidal pressure.
