Abstract
The utility model provides a positive end expiratory pressure valve control structure which comprises a connector 2, an exhalation vale 8, a flow proportional valve 5 and a current-limiting capillary copper pipe 1, wherein the connector 2 is provided with three connecting ports, an air inlet end of a positive end expiratory pressure (PEEP) cavity of the exhalation vale 8 is connected with a first connecting port of the connector 2, the flow proportional valve 5 is mounted on a proportional valve mounting seat 4, and the capillary copper pipe is connected with a third connecting port of the connector 2. According to the positive end expiratory pressure valve control structure, the air inlet of the PEEP cavity body of the exhalation vale 8 is provided with a fixed low flow and fixed pressure input through the current-limiting capillary copper pipe 1, a branch is arranged on the connector 2, the flow proportional valve 5 is used for controlling size of an aperture of cut-through atmosphere so as to change flow of released gas, so that size of pressure of the PEEP cavity of the exhalation vale 8 is changed. Mating requirements for the flow proportional valve 5 and a hardware platform aspect are relatively lowered, while an air outlet end of the flow proportional valve 5 is communicated with the atmosphere, the size of the aperture of the atmosphere is directly controlled by the proportional valve, so that the atmosphere can rapidly react along with the adjustment of the valve, retardation time is shortened, and reliability of a breathing machine is improved.
Description
Technical field
This utility model relates to (respirator is to belong to III kind equipment in the medical apparatus and instruments) very important safety component in a kind of respirator, be specifically related to end expiratory positive pressure (posit ive end-expiratory pressure, the PEEP) valve control system for respirator and anesthetic machine.
Background technology
Respirator and anesthetic machine make air flue still keep certain malleation by the PEEP valve at the end of exhaling, alveolar is unlikely complete atrophy, the alveolar that the alveolar that withers is enlarged and do not open is opened again, thereby can increase the compliance of functional residual capacity and lung, is conducive to oxygen by exhaling the film disperse.Therefore, PEEP can effectively accelerate repair process by improving oxygenate, avoids damaging lung tissue, for Comprehensive Treatment wins chance, so have the important performance indications that the PEEP function has become China's medical breathing machine.The pressure of PEEP is from low-level 0.29-0.49kPa (3-5cmH
2O) beginning increases to 0.98kPa (10cmH gradually
2O), generally should not surpass 1.96kPa (20cmH
2O).Accomplish that in so little scope fine adjustment and fast reaction are exactly a great problem.Existing PEEP valve pressure control has two classes: the direct usage ratio electric magnet of class band dynamic diaphragm, and another kind of use traffic proportional solenoid Indirect driven diaphragm wherein also has modification to use, and stability and reliability are still waiting to determine.
The utility model content
The purpose of this utility model is to provide the end expiratory positive pressure valve control structure that solves the pressure controlled fast reaction of PEEP valve and fine adjustment and stability under a kind of considering not increasing the respirator cost.
For solving the problems of the technologies described above, this utility model end expiratory positive pressure valve control structure comprises: adapter, described adapter have three connectivity ports; Exhalation valve, described exhalation valve PEEP chamber is connected with the first connectivity port of described adapter; The proportioning valve mount pad, air inlet one end of described proportioning valve mount pad is connected with the second connectivity port of described adapter; Flow proportion valve, described flow proportion valve are installed on the described proportioning valve mount pad; The current limliting capillary brass pipe, described capillary brass pipe is connected with the 3rd connectivity port of described adapter.
Described flow proportional valve housing is connected in the branch of the inlet end in described exhalation valve PEEP chamber.Described flow proportion valve is installed on the described proportioning valve mount pad by the valve hold-down screw.Two ends at described proportioning valve mount pad are provided with hydraulic quick coupler.Directly connect with flexible pipe between described exhalation valve, described proportioning valve mount pad and the described current limliting capillary brass pipe.
The distinguishing feature of this utility model end expiratory positive pressure valve control structure be design very simple, in traditional structure, change the riding position of flow proportion valve, make it to place a branch of the inlet end of exhalation valve PEEP cavity, can ignore on cost, this branch directly leads in atmosphere.Control the caliber size of this branch with flow proportion valve, discharge fast the gas of inlet end in the PEEP cavity according to PEEP pressure needs, thereby reach quick change PEEP pressure size, require corresponding reduction for flow proportion valve and hardware platform aspect supporting, along with the adjusting of valve can fast reaction, shorten lag time, improved the reliability of respirator.

The specific embodiment
Below in conjunction with accompanying drawing this utility model end expiratory positive pressure valve control structure is described in further detail.
Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this utility model end expiratory positive pressure valve control structure, comprise: adapter 2, adapter 2 comprises three connectivity ports, three ports are connected with the proportioning valve mount pad with current limliting capillary brass pipe 1, exhalation valve 8 respectively and are connected, the periphery of current limliting capillary brass pipe 1 is the double-deck barb of Pagoda-shaped, can connect closely with gas path pipe.Flow proportion valve 5 is installed on the proportioning valve mount pad 4 by valve hold-down screw 6, is provided with the first hydraulic quick coupler 3 and the second hydraulic quick coupler 7 at the two ends of proportioning valve mount pad 4.
The distinguishing feature of this utility model end expiratory positive pressure valve control structure be design very simple, in traditional structure, change the riding position of flow proportion valve, make it to place a branch of the inlet end of exhalation valve PEEP cavity, can ignore on cost, this branch directly leads in atmosphere.Control the caliber size of this branch with flow proportion valve, discharge fast the gas of inlet end in the PEEP cavity according to PEEP pressure needs, thereby reach quick change PEEP pressure size, require corresponding reduction for flow proportion valve and hardware platform aspect supporting, along with the adjusting of valve can fast reaction, shorten lag time, improved the reliability of respirator.
The preferred embodiment of below this utility model having been created specifies, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of this utility model creative spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
