Tracheal catheter protection device capable of being pulled open

Abstract

The invention, which relates to the technical field of medical instruments, discloses a tracheal catheter protection device capable of being pulled open. The tracheal catheter protection device comprises a protective sleeve and a trachea cannula. The trachea cannula is movably connected into the protective sleeve; the top end of the trachea cannula is attached to the top end of an inner cavity ofthe protective sleeve; one side of the trachea cannula is communicated with a tracheal catheter; and a tracheal guide core is sleeved in the inner cavity of the tracheal cannula. A first shell and a second shell are fixedly connected to the bottom of the protective sleeve; and a connecting piece is arranged between the first shell and the second shell. With the protective sleeve, a zipper, the first shell and the second shell, the protective sleeve can isolate bacteria when the trachea cannula enters the oral cavity and the nasal cavity of a patient and the trachea cannula and the internal trachea guide core are exposed after the trachea cannula enters the valve position. Compared with the prior art, the tracheal catheter protection device has the following beneficial effects: the tracheacannula and the trachea guide core can be effectively prevented from being polluted by the bacteria and thus postoperative rehabilitation effect of the patient is improved, so that the use requirementis met.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, the invention relates to a protective device for a trachea tube that can be pulled apart. Background technique [0002] With the aging of the country's population, more and more elderly patients receive general anesthesia with endotracheal intubation, but these patients generally have more underlying diseases. If postoperative pulmonary infection occurs, the length of hospital stay will often increase and affect postoperative healing. Life-threatening due to pulmonary complications. Although clinical anesthesia training anesthesiologists pay attention to aseptic operation and preoperative oral cleaning, there are still many patients with postoperative pulmonary infection, and there is evidence that most of the infected bacteria come from anaerobic bacteria in the oral cavity. [0003] Clinically, endotracheal intubation is divided into oral and nasal routes. Or...

Problems solved by technology

[0003] Clinically, endotracheal intubation is divided into oral and nasal routes. Ordinary disposable sterile endotracheal tubes will inevitably bring bacteria in the oral cavity or nasal cavity into the lungs, causing bacteria to multiply in the lower respiratory tract, increasing The probability of lung infection after general anesthesia or in patients with long-term tubes, among them, nasal stones or nasal polyps fall off into the trachea tube and cause foreign bodies in the trachea caused by nasal intubation, resulting in hypoxemia in patients, severe It will be life-threatening. At present, there is no better way to solve it except to strengthen the concept of asepsis, aseptic operation and preoperative oral disinfection care. It is clear in textbooks that the postoperative complications and mortality of patients with neurosurgery craniotomy rank first. Therefore, it is of great clinical significance to prevent or reduce secondary pulmonary infection during invasive tracheal intubation
