Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a countable back-snapping device for children. Background Art

[0002] Pneumonia is a common respiratory disease in children. It is usually caused by a large amount of secretions and sticky sputum blocking the bronchial cavity, thus causing atelectasis. Children with severe cases usually use mechanical ventilation, which is prone to respiratory complications and reduces lung ventilation. CPT can effectively clear airway secretions, increase lung compliance, promote lung re-expansion, prevent respiratory complications, and promote recovery of children. As one of the important treatment methods of CPT, back percussion mainly uses gravity and mechanical force to make the sputum attached to the tracheal wall fall off and be easily discharged from the body.

[0003] At present, there are back-squeezing devices on the market, such as the back-squeezing device disclosed in Chinese patent CN203576881U. The user shakes the handle to make the clasp body contact the patient to clasp the back. For this back-squeezing device, it is necessary to keep clasping the back for a period of time to produce a useful sputum-squeezing effect on the patient, but the number of clasping backs is completely affected by the user, and there is no better means to calculate the number of times in daily use, and it can only be counted manually. If during the clasping back process, the user stops clasping the back due to other things or the need to rest, when clasping the back again, it is easy to make a counting error, resulting in too few times to achieve the corresponding clapping effect, or too many times to cause physical harm to the child.
