Problems solved by technology

At present, it is difficult to control the above two positive pressure values. In the prior art, there is a method to achieve control by installing a flow control valve. Through the adjustment of the opening of the valve body, it can be obtained by adjusting the different flow areas of the gas. Different positive pressure values, but in this way, the cleanliness of the gas is required higher, and the blockage of the flow control valve will make the work effective and bring the risk of use

Embodiment approach 1

[0046] Such as Figure 8 As shown, a protruding structure 22 is provided on the periphery of the adjusting ring 2 , and the protruding structure 22 penetrates the side wall 12 and drives the adjusting ring 2 to rotate along the strip-shaped hole 12 b provided on the side wall 12 . In this structural situation, the protruding structure 22 can be connected with the adjusting ring 2 through any connection method, such as threaded connection, bonding or welding, and the power to drive the protruding structure 22 to rotate can also be reasonably selected in the prior art. The fast rotation can be realized through the structure such as the cylinder, the slow rotation can also be realized through the rotation of the connecting rod and other structures driven by the motor, and even the rotation with variable speed can be realized, so that it can be closer to the real breathing process.

Embodiment approach 2

[0048] Such as Figure 9 As shown, a protruding structure 22 is provided at the end of one of the rotating rods 35 , and the protruding structure 22 penetrates the side wall 12 and drives the adjustment ring 2 to rotate along the strip-shaped hole 12 b provided on the side wall 12 . Similarly, under this structural situation, the protruding structure 22 can be connected with the rotating rod 35 through any connection method, such as threaded connection, bonding or welding, and the power to drive the protruding structure 22 to rotate can also be passed through a structure such as a cylinder. Realize fast rotation, or realize slow rotation through the rotation of structures such as connecting rods driven by the motor.

[0049] As a preference of the above embodiment, the contours of the first flow channel 21 and the second flow channel 12a are set so that after the two are overlapped, the impurities can be cleaned up by the air flow, so as to avoid the formation of impurities in...

Abstract

The invention relates to the technical field of mechanical devices, especially to a double-positive-pressure adjusting device for surgical breathing equipment. The device comprises: a first connectingpipe and a mounting ring, wherein an annular step surface is arranged in one end of the first connecting pipe, an annular groove is formed in the inner side of the first connecting pipe, an adjustingring is embedded in the annular groove, the adjusting ring is attached to the side wall, protruding relative to the annular step surface, of the end of the first connecting pipe, and a first circulation channel and a second circulation channel are correspondingly formed in the adjusting ring and the side wall; and the mounting ring is mounted at one end of the first connecting pipe, the adjustingring is limited in the annular groove after connection, at least two supports connected with two ends of the inner wall of the mounting ring are arranged in the mounting ring, the supports are arranged in an intersecting mode, filter screens are arranged in gaps, fan-shaped cover bodies capable of being folded and closed are arranged at the tops of the filter screens, and opening and closing of the fan-shaped cover bodies are achieved in the rotating process of the adjustment ring. According to the invention, two different positive pressure values are effectively provided, and the device is high in inclusivity to gas, capable of realizing effective filtration of gas flow and has extremely high safety.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a double positive pressure regulating device for surgical breathing equipment. 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. [0003] Continuous positive airway pressure is a major ventilator mechanical ventilation mode. Specifically, continuous positive pressure airflow is provided in the gas channel during inhalation, and a certain resistance is also provided during exhalation, so that the inhalation and exhalation process Two different positive pressure values ​​above atmospheric pressure are obtaine...
