Novel expiratory volume recorder

Abstract

The invention discloses a novel expiratory volume recorder. The novel expiratory volume recorder comprises a recorder body, a mounting block, a fixed block and a guide sleeve block, wherein a balancing weight is mounted at the lower end of the recorder body through bolts; a connecting shaft is mounted on the outer surface of the recorder body in a nested mode; a supporting frame is mounted on theouter surface of the connecting shaft in a penetrating mode; a movable roller is mounted at the tail end of the supporting frame in a nested mode; a reset spring is fixedly connected to the outer surface of the supporting frame; the outer end of the reset spring is connected with the outer surface of the recorder body; and the mounting block is mounted on the upper end surface of the recorder bodythrough bolts. According to the novel expiratory volume recorder, a nesting layer which is made of an elastic silica gel material and is in butt joint with the outer side of a preset hose can cooperate with a bonding layer to stably enhance the overall supporting softness and strength of the preset hose, so that the phenomenon that the preset hose is blocked when being bent is avoided, the instantaneous flow rate of expired gas is slowed down, and the problem that data recorded by the device are inaccurate due to the fact that the instantaneous flow rate of the expired gas is too high can beeffectively avoided.

Description

technical field [0001] The invention relates to the technical field of expiratory volume recorders, in particular to a novel expiratory volume recorder. Background technique [0002] When encountering a disease that seriously endangers human health, such as asthma or chronic obstructive pulmonary disease, due to the occasional and irregular onset of the disease, it is difficult to diagnose in the early stage. Therefore, medical personnel need to use a special expiratory volume recorder for diagnosis. and record medical work to prevent sudden dangerous phenomena in patients, so it is widely used by medical personnel, but the existing new type of expiratory volume recorder still has certain defects, such as: [0003] 1. The existing new type of expiratory volume recorder cannot fully guarantee the sealing degree of the butt joint when the exhalation tube is docked, which leads to easy leakage of the tube joint when the breathing volume or expiratory rate is large. There are b...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a new type of expiratory volume recorder to solve the problem that when the expiratory tube is docked in the above background technology, the sealing degree of the butt joint cannot be fully guaranteed, resulting in a large respiratory volume or expiratory rate. Under the circumstances, it is easy to cause air leakage or falling off at the butt joint of the pipeline, resulting in errors in the recording accuracy, not having good placement stability, and at the same time, the preset hose is prone to bending.
