Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a splash prevention device for tracheotomy patients. Background Art

[0002] Tracheotomy is a surgery that cuts the front wall of the cervical trachea and allows breathing through a newly established channel connected to the outside world. It is mainly used to rescue patients with laryngeal obstruction. When patients have difficulty breathing due to tumors or foreign objects blocking the pharynx or larynx, or respiratory dysfunction causing secretions blocking the lower respiratory tract, the patient will suffer from hypoxia and a large amount of carbon dioxide in the blood, so that there is a risk of suffocation and death. At this time, simply giving the patient oxygen cannot relieve the patient's hypoxia, but instead makes breathing more suppressed. Therefore, tracheotomy is needed to relieve the patient's respiratory tract obstruction and relieve breathing difficulties in order to achieve the purpose of auxiliary treatment.

[0003] However, during the incision process, exposure to aerosols and secretions from patients with respiratory diseases is a high-risk factor for infection for medical staff. Studies have shown that operations such as endotracheal intubation, sputum suction, and nebulizer treatment will generate a large amount of aerosols and droplets. Compared with non-exposed personnel, the infection rate of medical staff exposed to such high-risk operations is 2.86 times higher. During the care of tracheotomy patients, the aerosol or secretion splashing of the patient needs to be controlled to avoid cross infection. Summary of the invention

[0033] When used specifically, the connecting short tube 8 in the device of the present invention is connected to the three-way tube connected to the endotracheal tube. When the endotracheal tube needs to be replaced or removed, the residual secretions of the patient are sucked to prevent the secretions from splashing due to external stimulation when the endotracheal tube is removed. The medical staff holds the outer wall of the hand-held fixed ring 27 wrapped around the inner ring 10 with one hand, and twists the rotating ring 21 with the other hand, and drives the negative pressure ring chamber 14 to generate through the fixed ring 20 fixed to the rotating ring 21.

The puncture needle 6 connects the negative pressure ring cavity 14 and the connecting short tube 8. As the negative pressure in the connecting short tube 8 The annular cavity 14 forms a negative pressure state to suck secretions, and the secretions enter the negative pressure annular cavity 14 through the one-way valve plate 9 in the connecting short tube 8. When a large amount of secretions flow in instantly and fill the negative pressure annular cavity 14, the sliding ring 12 slides downward to squeeze the compression spring 30, and the sliding ring 12 and the outer ring 23 are distanced to receive the secretions. When the suction is stopped, if it is analyzed that there are still secretions, a new device is replaced until the secretions are no longer sucked out.
