Automatic back knocking device

Abstract

The invention discloses an automatic back knocking device. The automatic back knocking device comprises a mechanical arm, and a back knocking hand used for knocking the back is installed on one side of the mechanical arm. The automatic back knocking device is scientific and reasonable in structure and safe and convenient to use, under the effect of a mechanical palm, the back knocking manipulationformed through gathering and bending of the real palm is conveniently simulated, and the real back knocking feeling is provided for a patient to the greatest extent; under the effect of a driving motor, a drive gear rotates, therefore in cooperation with the effects of a big gear, a transmission arm, a movable shaft, a connection arm and a connection shaft, a swing arm reciprocatingly swings, incooperation with the effect of a stretching rod, the mechanical palm is driven to swing reciprocatingly, and therefore the automatic back knocking operation is achieved; the phenomenon can be avoidedthat the fatigue is generated like manual back knocking with increase of the back knocking time, so that the hand form for back knocking is changed, the back knocking strength is reduced, and the backknocking effect is influenced, and the device is more reliable to use.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to an automatic back tapping device. Background technique [0002] Long-term bedridden patients have poor lung drainage and are prone to pulmonary infection. They need to turn over and tap their back frequently to facilitate the discharge of sputum. The existing method of tapping their back is to tap their back with their hands, which requires the operator to have a certain hand shape , so that the fingers are brought together and bent to form a bowl shape, and the back tapping work is performed. Because the force of manual tapping is uneven each time, it is difficult to grasp the severity, and the frequency of tapping the back is low, which affects the effect of tapping the back. The increase of back-knocking time will make the nurses prone to fatigue and energy decline, making it difficult to maintain the shape of the back-knocking hand, which will affect the work of the back...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides an automatic back-knocking device, which can effectively solve the problem that the existing back-knocking method proposed in the above-mentioned background technology is to use hands to knock the back, requiring the operator to have a certain hand shape when doing the back-knocking, so that the fingers are brought together and bent to form a Bowl-shaped, back-knocking work, because manual back-knocking power is used unevenly each time, it is difficult to grasp the severity, and the frequency of back-knocking is low, which affects the effect of back-knocking Fatigue and decreased energy make it difficult to maintain the shape of the back-knocking hand, which affects the work of the back-knocking, and at the same time increases the pulling amount of the nursing staff, which is laborious and laborious
