A portable assisted respirator

Abstract

The present invention relates to the field of medical equipment, more specifically a portable assisted respirator, including a mounting shell, a rear cover, a main body frame, an air passage, an air outlet passage, a driving structure, a central extrusion mechanism, a transmission frame, a side extrusion Mechanism and air bag group, the device uses the driving structure to drive the middle extrusion mechanism and the side extrusion mechanism to move relative to each other through the transmission frame, and then squeezes the two air bag groups to make it blow air into the patient's body. During the rotation process of the driving structure , the central extrusion mechanism and the side extrusion mechanism reciprocate, and then realize reciprocating air blowing. The airbag group is provided with a sufficient amount of blowing capacity by multiple small-volume airbags. The small-volume airbags have a small volume and their volume recovery rate after being compressed The block can satisfy the gas output at a fast frequency, so that the patient can be effectively insufflated, and the driving structure is manual operation, which is not limited by electricity.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a portable auxiliary respirator. Background technique [0002] For example, the publication number is CN110478586A, a portable artificial respirator for first aid. The invention discloses a portable artificial respirator for first aid, which includes an air bag, and the two sides of the air bag are respectively provided with an air inlet and an air outlet, and the air outlet is movably connected. The air tube with a one-way valve, the side of the air tube is connected with a mask, the air bag is fixedly installed in the box, the air inlet and the air outlet on the air bag pass through the box, and are fixed on the box by a locking ring, the box A pressing device is arranged on one side of the airbag, and the pressing device includes a U-shaped plate that is movably connected with the box body and is placed on the side. The side is movably connected with a motor, the transmission...

AI Technical Summary

Problems solved by technology

If the patient still does not recover spontaneous breathing, continue to insufflate. The frequency of insufflation is 12 times / min for adults, 15 times / min for children, and 20 times / min for infants. Inhalation frequency is more important. The first two insufflations should last for 1-2 seconds each time, that is to say, after the initial artificial respiration, the patient has not yet recovered spontaneous breathing. Whether it is an adult, a child or an infant, a fast frequency is required. And a sufficient amount of gas is input, and the device is only equipped with one air bag, which needs a large enough volume to meet the required blowing volume, and the volume recovery speed of the large-volume air bag cannot be recovered quickly after being pressed. Just can't guarantee that enough air volume can be input every time, and can't reach the treatment effect, and this device utilizes motor-driven device to work, can only utilize electric drive, promptly use storage battery or connect power supply, and this just makes can't guarantee in some cases. The normal use of the device, such as the battery is dead or there is no power supply around, so that the patient cannot be treated effectively
