Embodiment 1

[0037] Embodiments of the present invention provide a ventilator that runs smoothly and prevents airflow disturbances, such as figure 1 shown, including:

[0038] Ventilator body 1. In modern clinical medicine, the ventilator, as an effective means of artificially replacing the autonomous ventilation function, has been widely used for respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, and respiratory support therapy. and emergency resuscitation, occupy a very important position in the field of modern medicine, belong to the prior art, and will not repeat them;

[0039] A steady flow component, which is installed in the oxygen output pipe 16 of the ventilator body 1, is used to stabilize the airflow;

[0040] Specifically, such as figure 2As shown, the flow stabilization assembly includes a hollow floating ball 23, a breather sleeve 17, an outer screw rod 19, an inner screw sleeve 18 and a first impeller 22, and the hollow ...

Embodiment 2

[0047] On the basis of Example 1, such as Figure 4-5 As shown, it also includes an air suction assembly 26, which is used to provide power for the flow of oxygen in the oxygen delivery pipe. The air suction assembly 26 is arranged in the oxygen delivery pipe. The suction assembly 26 includes a motor 27 and a second impeller 29. The motor 27 is used to drive the second impeller 29 to rotate. The motor 27 is installed in the oxygen delivery pipe through a fixed rod. Preferably, the suction assembly 26 also includes a transmission mechanism connected to Between the output shaft of the motor 27 and the second impeller 29, the transmission mechanism includes a rotating sleeve 28, a transmission sleeve 30 and a linkage rod 31. The rotating sleeve 28 is rotatably fitted on the output shaft of the motor 27, and the second impeller 29 is fixedly mounted on the rotating sleeve 28, one end of the transmission sleeve 30 is open and the other end is closed. The output shafts are respecti...

Embodiment 3

[0049] On the basis of Example 2, such as Figure 6 As shown, the suction assembly 26 also includes an adjustment mechanism for adjusting the rotational speed of the motor 27, which is connected in series with the power supply line of the motor 27. The adjustment mechanism includes a resistor 34 and a conductive block 33, and one end of the resistor 34 is connected to a conductive block. The blocks 33 are respectively connected to the power supply wires, and the conductive block 33 is slidably connected to the resistor 34. An insulating rod 35 is fixed on the conductive block 33, and an installation sleeve 36 is fixed on the end of the insulating rod 35 away from the conductive block 33, and the installation sleeve 36 is rotatably mounted on the On the linkage rod 31, when the hollow floating ball 23 moves, the insulating rod 35 drives the conductive block 33 to move, thereby changing the size of the resistance 34 connected to the power supply line, changing the magnitude of th...

Abstract

The invention is applicable to the technical field of medical equipment, and provides a stable-operation anti-airflow-disturbance breathing machine which comprises a breathing machine body; a flow stabilizing assembly is installed in an oxygen output pipe of the breathing machine body and used for stabilizing airflow; the flow stabilizing assembly comprises a hollow floating ball, a ventilation sleeve, an outer spiral rod, an inner spiral sleeve and a first impeller, and the portion, between the inner spiral sleeve and the hollow floating ball, of the outer spiral rod is sleeved with a first spring; the first impeller is fixedly installed on the side, away from the outer spiral rod, of the hollow floating ball. The ventilation sleeve is fixed to the inner wall of the oxygen output pipe, the flow stabilizing assembly is arranged, when the flow speed of oxygen is too high, the hollow floating ball is pushed to move, the distance between the hollow floating ball and the inner wall of the ventilation sleeve is larger and larger when the hollow floating ball moves, meanwhile, the outer spiral rod drives the first impeller to rotate, and when the first impeller rotates, acting force opposite to the flowing direction is generated on the oxygen, the flow velocity of oxygen is further slowed down, and the flow stabilizing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a ventilator which runs smoothly and prevents airflow disturbance. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients; [0003] Existing ventilators, when in use, sometimes have unstable oxygen supply, and are easily disturbed to cause changes in the oxygen flow, which may cause insufficient or excessive oxygen supply to the patient, and then manually ...
