Chest wall negative pressure supporting device

Abstract

The invention discloses a chest wall negative pressure supporting device. The chest wall negative pressure supporting device comprises a plastic supporting body used for being attached to the outer side of a chest wall in a sealed mode, wherein a flow guide groove is formed in the middle of the side surface being in contact with the outer side of the chest wall, of the plastic supporting body, anda negative pressure aspirator is arranged on the side surface away from the outer side of the chest wall, of the plastic supporting body. An air inlet of the negative pressure aspirator communicateswith the flow guide groove through a negative pressure air outlet formed in the plastic supporting body, and an exhaust port of the negative pressure aspirator communicates with an exhaust pipe. Compared with the prior art, the chest wall negative pressure supporting device has the advantages that the plastic supporting body is tightly attached to the outer side of the chest wall in a sealed mode,the plastic supporting body forms an outer bracket on the outer side of the chest wall to simulate ribs for supporting, swing of a longitudinal diaphragm is prevented, and the process of an on-site treatment operation is simple; and in addition, the chest cavity of a patient cannot be compressed, secondary injury to the patient cannot be caused, and the pain of the patient is greatly relieved.

Description

technical field [0001] The invention relates to the technical field of medical structures, in particular to a chest wall negative pressure support device. Background technique [0002] "Flail chest", also known as multiple multiple rib fractures, is a critical condition of acute chest trauma, and its mortality rate is about 25%. The main factor leading to its fatality is the swing of the mediastinum. [0003] The current on-site first aid methods for "flail chest" include cotton pad packing, skin / rib external traction, and tracheal intubation, but the method of cotton pad packing is likely to cause chest compression for patients, and the operation is performed during the process of skin / rib external traction It is difficult and easy to cause severe pain to the patient, and it is also difficult to perform first aid on the spot by means of endotracheal intubation.
