Description

Technical Field

[0001] The utility model relates to pressure flow detection equipment for a breathing machine, belonging to the technical field of pressure flow detection equipment. Background Art

[0002] A ventilator is a medical device that delivers oxygen-containing air into the lungs and expel carbon dioxide-containing gas from the body to help the respiratory system complete ventilation. It mainly applies pressure directly at the opening of the respiratory tract. When inhaling, the gas is pressurized and pressed into the alveoli. When exhaling, the gas is passively recovered by the chest and lungs and expelled from the body. However, before using the ventilator, the pressure and flow of the ventilator need to be tested to ensure that the ventilator meets the specified standard values.

[0003] There are still some problems in the use of existing pressure flow detection equipment for ventilators. During the detection, the outlet pipe of the ventilator needs to be connected to the inside of the detection equipment. Most of the current connections use sealing rings and wire winding, which is not only troublesome, but also easy to cause the outlet pipe of the ventilator to fall off, resulting in inaccurate detection. In addition, when the pressure flow detection equipment is in use, there is no moving device on its outside, so it cannot be applied to different workplaces. Utility Model Content

It can quickly connect the outlet pipe of the ventilator to the detection device, while preventing the outlet pipe from falling off. It can also facilitate the movement of the detection device, thereby adapting to different working environments to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The pressure flow detection device of the ventilator comprises a detection device body, a sensor is fixedly connected to the outer side of the detection device body, a gas intake pipe is fixedly connected to the top of the sensor, a gas guide hose is clamped inside the gas intake pipe, a connecting plate is fixedly connected to the top of the gas intake pipe, an electric telescopic rod is fixedly connected to the outer side of the connecting plate, a moving rod is fixedly connected to the outer side of the electric telescopic rod, a connecting groove is fixedly connected to the bottom of the moving rod, a rotating tube is fixedly connected to the outer side of the connecting groove, a rotating tube is rotatably connected to the inside of the rotating tube, a bidirectional screw is fixedly connected to the outer side of the rotating rod, a bolt is threadedly connected to the outer side of the bidirectional screw, a clamping groove is opened in the inner wall of the gas intake pipe, a sliding rod is fixedly connected to the bottom of the bolt, and a clamping cover is fixedly connected to the bottom of the sliding rod.

[0007] Furthermore, a groove is provided at the inner top of the main body of the detection equipment, a fixing rod is fixedly connected inside the groove, a sliding ring is slidably connected to the outer side of the fixing rod, a stabilizing rod is fixedly connected between the sliding rings, a supporting rod is fixedly connected to the top of the stabilizing rod, a mounting plate is fixedly connected to the top of the supporting rod, and an expansion screw is movably connected inside the mounting plate.

[0008] Furthermore, the electric telescopic rod and the movable rod are located above the air intake pipe, and the interior of the connecting groove is hollow.

[0009] Furthermore, the bidirectional screw rod is rotatably connected to the inside of the connecting groove through a rotating rod, and the bolts are symmetrically distributed on the outside of the bidirectional screw rod.

[0010] Furthermore, the clamping cover is symmetrically distributed below the connecting groove through the sliding rod, and the clamping cover and the clamping groove are on the same plane.

[0011] Furthermore, the fixing rods are symmetrically distributed inside the groove, and the number of the sliding rings is the same as the number of the fixing rods.

[0012] Furthermore, the mounting plate is mounted above the main body of the detection device via a support rod, and the expansion screws are symmetrically distributed inside the mounting plate.

[0013] The beneficial effects of the utility model are:

[0014] (I) The utility model sets up a detection device body. First, the air guide hose of the ventilator enters the interior of the air intake pipe. At this time, the air guide hose is located between the two clamping covers. At this time, the rotation of the rotating rod inside the rotating tube drives the two-way screw to rotate inside the connecting groove. Since the outer side of the two-way screw is threaded with a bolt, the bolt is rotated by the rotation of the two-way screw. Since a sliding rod is fixedly connected to the bottom of the bolt, and the clamping cover is connected to the bottom of the connecting groove through the sliding rod, when the two-way screw rotates, the bolts will be driven to move away from or close to each other. The approach of the two bolts drives the clamping cover at the bottom of the sliding rod to move close to each other, thereby clamping the air guide hose. At this time, the electric telescopic rod is started to drive the moving rod to move, so that the clamping cover at the bottom of the moving rod enters the clamping groove inside the air intake pipe. At this time, the air guide hose can be positioned and prevented from falling off.

[0015] (ii) The utility model is provided with a detection device body, and a groove is opened in the inner top of the detection device body.
