Abstract
The invention relates to an oxygen flow rate control device for an anaesthesia machine. An air bag is arranged in the anaesthesia machine, one end of the air bag is connected with a pure oxygen pipeline, an oxygen flow rate knob switch is arranged on the pure oxygen pipeline, a check valve is arranged between the pure oxygen pipeline and the air bag, an air pipeline is arranged in parallel at a connecting part of the pure oxygen pipeline and the air bag, an oxygen concentration sensor is also arranged on the pure oxygen pipeline and is connected with a controller of the anaesthesia machine, and the control end of a valve is connected with the controller of the anaesthesia machine. The knob switch with the minimum limit flow rate being 0.3L/min is adopted in the oxygen pipeline, the supply of the oxygen at the minimum physiologically required flow rate for patients is ensured, the air pipeline is arranged in parallel to the oxygen pipeline, when the concentration of oxygen in gas supplied by the oxygen pipeline is smaller than 20 percent, the valve arranged on the air pipeline is opened, the risk of oxygen shortage and insufficient ventilation of general anesthetic patients because of oxygen flow rate meter closing or unexpected oxygen source cutoff is avoided, and the safety of the existing anaesthesia machine is improved.
Description
Technical field:
The present invention relates to the mankind life article, relate in particular to medical instruments field, particularly anesthetic machine, concrete is a kind of oxygen flow control device that is used for anesthetic machine.
Background technology:
Anesthetic machine is widely used in general anesthesia.In the prior art; Be provided with 2～3 effusion meters in the anesthetic machine; Oxygen flowmeter is not wherein opened in the clinical anesthesia process, is perhaps closed by mistake, when perhaps the oxygen source accident is cut off, all can cause the oxygen supply amount to cross the low oxygen supply that perhaps do not have; Cause phenomenons such as patient's hypoventilation, hypoxemia, bring threat for patient's life security.
Summary of the invention:
The object of the present invention is to provide a kind of oxygen flow control device that is used for anesthetic machine, the described this oxygen flow control device that is used for anesthetic machine will solve the prior art anesthetic machine and cross the technical problem that does not have remedial measure when hanging down at oxygen flow.
This oxygen flow control device that is used for anesthetic machine of the present invention; Comprise anesthetic machine, air bag, oxygen concentration sensor, check valve and protection valve, wherein, be provided with controller in the described anesthetic machine; The air inlet of described air bag is connected with the outlet of described check valve; The inlet of check valve connects a three-way pipeline, and an end of described three-way pipeline connects a pure oxygen pipeline, and the other end of three-way pipeline connects an air line; Described oxygen concentration sensor is arranged in the pure oxygen pipeline; Described protection valve is arranged in the air line, and described controller is connected with oxygen concentration sensor through holding wire, and controller is connected with the protection valve through control line.
Further, described check valve is made up of a unidirectional flap valve device.
Further, described protection valve is made up of an electromagnetic valve.
Further, be connected with the oxygen flow adjusting knob on the described controller, described oxygen flow adjusting knob is made up of an inner button and an outer shroud knob, and described outer shroud knob sleeve is located on the excircle of inner button.
Operation principle of the present invention is: the gas outlet of air bag is connected with the patient respiration road, and the outer shroud knob is closed and inner button when opening into maximum, the oxygen flow of control anesthetic machine output 0.8L/min; When the outer shroud knob was closed, inner button can make oxygen flow between 0.3～0.8L/min, regulate; When outer shroud knob and inner button were all closed, anesthetic machine still had the oxygen flow of 0.3L/min, to guarantee patient safety.Oxygen concentration sensor records fraction of inspired oxygen and equals greatly at 20% o'clock, and the protection valve on the controller control air pipeline is in closed condition, uses source of oxygen that the patient is carried out oxygen supply; When oxygen concentration sensor records fraction of inspired oxygen less than 20% the time, controller is opened the protection valve on the air line.When lifting motion on the air bag, unidirectional flap valve is open, the air admission reservoir bag, and when reservoir bag pressed down, unidirectional flap valve was closed, and the gas of set amount gets into the patient respiratory road, guarantees that patient's oxygen supplies.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention is provided with the rotary switch that the least limit flow is 0.3L/min on the anesthetic machine controller, can ensure to the oxygen flow that the patient supplies with minimum physiological need; The parallelly connected air line that is provided with oxygen channel; When oxygen concentration in the oxygen channel is opened the protection valve on the air line less than 20% the time; Avoid owing to oxygen flowmeter is closed the patient with general anesthesia anoxia that causes with the oxygen source accidental amputation, the danger of hypoventilation, improve the safety of anesthetic machine.
Description of drawings:
Fig. 1 is a kind of structural representation that is used for the oxygen flow control device of anesthetic machine of the present invention.
Fig. 2 is the structural representation of the oxygen flow rotary switch among the present invention.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, a kind of oxygen flow control device that is used for anesthetic machine of the present invention comprises anesthetic machine (not shown), air bag 1, oxygen concentration sensor 7, check valve 4 and protection valve 6; Wherein, Be provided with the controller (not shown) in the described anesthetic machine, the air inlet of described air bag 1 is connected with the outlet of described check valve 4, and the inlet of check valve 4 connects a three-way pipeline; One end of described three-way pipeline connects a pure oxygen pipeline 2; The other end of three-way pipeline connects an air line 5, and described oxygen concentration sensor 7 is arranged in the pure oxygen pipeline 2, and described protection valve 6 is arranged in the air line 5; Described controller is connected with oxygen concentration sensor 7 through holding wire, and controller is connected with protection valve 6 through control line.
Further, described check valve 4 is made up of a unidirectional flap valve device.
Further, described protection valve 6 is made up of an electromagnetic valve.
Further, be connected with the oxygen flow adjusting knob on the described controller, described oxygen flow adjusting knob is made up of an inner button 31 and an outer shroud knob 32, and described outer shroud knob 32 is set on the excircle of inner button 31.
The work process of present embodiment is: outer shroud knob 32 is closed and inner button 31 when opening into maximum, the oxygen flow of control anesthetic machine output 0.8L/min; When outer shroud knob 32 was closed, inner button 31 can make oxygen flow between 0.3～0.8L/min, regulate; When outer shroud knob 32 was all closed with inner button 31, anesthetic machine still had the oxygen flow of 0.3L/min, to guarantee patient safety.Oxygen concentration sensor 7 records fraction of inspired oxygen and equals greatly at 20% o'clock, and the protection valve 6 on the controller control air pipeline 5 is in closed condition, uses source of oxygen that the patient is carried out oxygen supply; When oxygen concentration sensor 7 records fraction of inspired oxygen less than 20% the time, controller is opened the protection valve 6 on the air line 5.When lifting motion on the air bag 1, unidirectional flap valve is open, air admission reservoir bag 1, and when reservoir bag 1 pressed down, unidirectional flap valve was closed, and the gas of set amount gets into the patient respiratory road, guarantees that patient's oxygen supplies.
