The utility model discloses an electronic control expiratory valve with a respirator. The electronic control expiratory valve with the respirator comprises a valve body, a diaphragm, a press piece, a press cover and further comprises a pressure controller. The pressure controller comprises an outer magnet yoke, an inner magnet yoke, a coil, magnets, a press head and clamping rings. The inner magnet yoke is arranged in the outer magnet yoke, the magnets are arranged between the outer magnet yoke and the inner magnet yoke and tile-shaped, a magnetizing direction is radial and faces an N pole on one side and faces an S pole on the other side. A plurality of magnets are evenly distributed in an inner cavity of the outer magnet yoke, a radial guiding groove is arranged in the inner magnet yoke, one end of the coil is arranged in the guiding groove, the other end of the coil is provided with a press head, the clamping ring is arranged at the bottom of the outer magnet yoke, and threads are arranged on the outer magnet yoke and connected with the press cover of the expiratory valve. A wire of the coil is connected with a microcomputer control circuit, on-off and magnitude of current is controlled by the microcomputer, and therefore end-expiratory pressure of a patient can be accurately controlled.
Description
Technical field
This utility model relates to a kind of microcomputer controlled expiratory 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, electric electricing breathing machine and the Pneumatic electrical control respirator.
Background technology
Respirator is mainly used in treating respiratory failure clinically, and anesthetic machine is mainly used in being the patient of General anesthesia, and is in operation and therapeutic process, significant to patient's treatment according to the pressure of patient's state of an illness fine adjustment patient end-tidal.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
The purpose of this utility model is to overcome the defective of existing mechanical type outlet valve, and a kind of automatically controlled outlet valve is provided, and can effectively overcome this defective.
Scheme of the present utility model is as follows:
A kind of automatically controlled outlet valve of respirator, 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 radial magnetizing, and one to the N utmost point one to the S utmost point, and some blocks of Magnet are uniformly distributed in the outer yoke inner chamber.
The wire 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, so that gas enters 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 accurately the pressure of patient's end-tidal.

The specific embodiment
Among Fig. 1, the automatically controlled outlet valve of a kind of respirator 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 controlled expiratory 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 radial magnetizing, and one to the N utmost point one to the S utmost point, and 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 is so that coil 9 can only slide up and down 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 fixedly inner yoke; Coil 9 is connected with external power source by wire 14.Coil 9 is wound on the bobbin, and when passing into 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 controlled expiratory 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 upwards pressed tabletting 3 in the top, makes diaphragm 2 sealing outlet passageways, gas can't be discharged by gas outlet 6, so that gas enters patient pulmonary; When patient exhales, turn-off current, bobbin is because deadweight is fallen, and diaphragm 2 is opened, and patient's Exhaled gasesS 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.
