2. The utility model relates to an use piston and inflator cooperation to produce gaseous transport to respirator, the design principle is simple reasonable, and processing is simple and convenient.

3. The utility model discloses a bent axle connecting rod links up piston and wheel, and the rotation of wheel drives the piston acting when marcing through removing the sick bed, has liberated anesthesiologist's both hands, makes anesthesiologist can fully look after not clear-headed disease of anesthesia, is provided with the scale mark on the bent axle connecting rod, can energy gasification air output, and the anesthesiologist of being convenient for judges the recovery condition of disease.

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Detailed Description

As shown in figure 1, the utility model comprises a cylindrical inflator 1, a piston 2 and a breathing mask 3 fixed at the mouth and nose of a patient for supplying gas breath, wherein the piston 2 is arranged in the inflator 1 in a flat cylindrical shape, the piston 2 is in gapless fit with the inner wall of the inflator 1, the piston 2 is fixed on a movable sickbed through a crankshaft connecting rod 5, one side of the crankshaft connecting rod 5 is fixed on the rim of a wheel 4 of the movable sickbed, the other end of the crankshaft connecting rod 5 passes through the bottom surface of the inflator 1 and is fixedly connected with the piston 2, the bottom surface of the inflator 1 is provided with a gas outlet, the gas outlet is communicated with the breathing mask 3 through a gas hose 6, so that the crankshaft connecting rod 5 is driven to work through the rotation of the wheel 4 in the advancing process of the movable sickbed, and the piston 2 is driven to do reciprocating linear motion in the inflator 1 to achieve, the air cylinder 1 is provided with an air inlet hole.

In this embodiment, the end of the crankshaft connecting rod 5 fixedly connected with the piston 2 is provided with a scale mark 8 for controlling the air delivery amount by controlling the depth of the crankshaft connecting rod 5 penetrating into the inflator 1, so that the medical staff can conveniently quantify the air delivery amount.

In this embodiment, the piston 2 is made of elastic rubber, so that the piston 2 has certain elasticity and is tightly attached to the inner wall of the cylinder 1 to ensure sufficient air tightness.

In this embodiment, the outer side wall of the air cylinder 1 is provided with a fixing buckle 7, so that the air cylinder 1 can be flexibly fixed on a movable sickbed according to the body shape and position of a patient.

In the embodiment, the air inlet hole is provided with the one-way valve which can only feed air, and the air inlet hole and the air outlet hole are both arranged on the end surface of the air cylinder 1 opposite to the piston 2, so that the condition that the air is conveyed due to the position of the piston 1 is avoided, a medical oxygen bag can be connected to the air inlet hole of a patient needing oxygen conveyance, and the air inlet hole of the patient needing no oxygen conveyance only needs to be in direct contact with air.
