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

Embodiment 1

[0026] The present invention provides a protective device for a pullable tracheal tube, comprising a protective sheath 1 and a tracheal intubation tube 10, the tracheal intubation tube 10 is movably connected in the protective sheath 1, and the top end of the tracheal intubation tube 10 is in contact with the protective sheath 1 The top of the endotracheal tube 10 is connected to the top of the endotracheal tube 10, and the endotracheal tube 10 is connected to the endotracheal tube 12. The inner cavity of the endotracheal tube 10 is covered with a trachea guide core 11, and the bottom of the protective cover 1 is fixedly connected to the first housing 5. and the second shell 6, a connecting piece 7 is arranged between the first shell 5 and the second shell 6, and the first shell 5 and the second shell 6 are fixedly connected by the connecting piece 7, and the One side of the protective cover 1 is provided with a zipper 2, the zipper 2 is provided with a steel wire 3, and the en...

Embodiment 2

[0034] Such as Figure 1-5 As shown, the embodiment is specifically: when intubating a minor patient, when intubating through the mouth / nose, when the tip of the protective sheath 1 and the tip of the endotracheal tube 12 enter the front of the glottis, they are driven by pulling the ring 8 The steel wire 3 simultaneously drives the buckle 4 to pull the zipper 2. After the zipper 2 on one side of the protective cover 1 is pulled open by the pull buckle 4, the tracheal intubation tube 10 in the protective cover 1 is pulled out, and the pull ring 8 is pulled backward to drive the steel rope to pull open and soft. Connector 7 separates the first shell 5 from the second shell 6 and fixes the protective sheath 1 and the endotracheal tube 10. The endotracheal tube 10 is sent into the endotracheal tube 12 when entering the glottis. When the endotracheal tube 12 is inserted to the depth When the child's age / 2+12cmcm is reached, continue to pull out the zipper 2 until the protective co...

Embodiment 3

[0036] The difference from Embodiment 1 is that this embodiment also discloses a protective device that can be pulled apart for the endotracheal tube. The outer wall of the tracheal intubation tube 10 is provided with a locking groove 13, and the locking groove 13 is an annular locking groove 13. A fixed snap ring 14 is snapped into the slot 13, and a disinfection rubber pad 15 is fixedly connected to the top of the fixed snap ring 14;

[0037] The fixing snap ring 14 is a medical elastic silicone ring.

[0038] Such as Figure 5-7 As shown, the embodiment is specifically: after the endotracheal tube 10 is inserted from the oral cavity, the fixing snap ring 14 can be snapped into the slot 13, and the disinfection rubber pad 15 can fit the patient's gums, and the fixing snap ring 14 can be placed on the patient's mouth. The sides of the teeth limit the position of the gums, avoiding the displacement and shaking of the endotracheal tube 12 in the oral cavity, ensuring the stabi...

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...
