Controllable timing back-patting sputum-excretion device

Abstract

The invention relates to the technical field of medical instruments, in particular to a controllable timing back-patting sputum-excretion device. The device comprises a back-patting device body, the back patting device body is of an inverted bowl-shaped structure, an opening is formed in the upper portion of the device body, an air bag is arranged on the circumference of the lower end face of theback-patting device body, a clamping rod is connected to an opening in the upper portion of the back-patting device body, the interior of the clamping rod is hollow, the clamping rod is connected witha handle body, the handle body is detachably connected with the clamping rod, the size of the opening, communicated with the outside, of an inner cavity of the back-patting device body can be adjusted, and impact of the back-patting device on a patient is reduced through buffering of the air bag, under the control of a two-way valve arranged on the air bag, the size of a negative pressure cavityduring slapping is effectively adjusted on the premise that the vibration effect is not influenced; after the air bag is in contact with back muscles, related respiratory muscles can be indirectly loosened by virtue of flapping impact force, so that the optimal sputum-excretion effect is achieved; the electronic prompting function is added to the back-patting device, a patient can be fully helpedto better discharge sputum, and the device is safe, effective and easy to operate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a controllable timing back-patting phlegm-expelling device. Background technique [0002] Patients with respiratory-related diseases or abnormal development of the respiratory system are likely to cause sputum accumulation, especially infants or children who need family members or nursing staff to participate in the process and give back pats to help expel sputum, that is, keep a hollow five fingers together with the palm of the hand 1. Arch the palm of the hand, from bottom to top, from the outside to the inside, and use the strength of the wrist to slap the patient's back. At the same time, there must be a certain strength, speed and area. The main principle is to loosen the viscera and surrounding respiratory muscles. , to help patients expel sputum. [0003] Prior art CN206304087U discloses a back-patting sputum-expelling device for children, including a back-patting...

AI Technical Summary

Problems solved by technology

[0004] The back-slapping sputum-expelling device disclosed in the above-mentioned patent can allow patients to use the back-slapping sputum-expelling device. However, due to the small weight of infants and young children, the small size of the back, and the large limitations of adults, the bowl of the back-slapping sputum-expelling device The negative pressure chamber formed by the back racket and the contact between the back racket and the back will have a greater impact on the back of the patient; and the strength of the back buckle is uneven, and it is difficult to control the force, which is easy to cause harm to the patient , especially for critically ill children who are being treated; in addition, if medical staff participate in giving back pats, the children will feel insecure and develop resistance. Therefore, let family members use simple, easy-to-learn, safe and effective equipment or instruments to give patients back pats , will produce a more effective expectoration effect
