Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of endotracheal tube, specifically a kind of bronchoscopy Special endotracheal tube.
Background technology
Branchofiberoscope is one of important means having become respiratory system disease clinical diagnosis and treatment at present.But as a kind of invasive inspection, before inspection and in checking process there is high-pressure in most of patients, the even feared state of mind, to such an extent as to checking process can not be coordinated well in checking, stimulate gas to also causing laryngospasm or bronchospasm during inspection, hypoxemia, severe arrhythmia, hemorrhage severe complication such as grade, conventional fibre bronchoscopy implements under Trachea Surface Anesthesia, patient can cause psychology frightened under waking state, produce sensation of asphyxia, and cause and hold one's breath, choke and cough, intense stimulus also can cause patients' blood to raise simultaneously, increased heart rate, easily bring out cardiovascular and cerebrovascular vessel unexpected, particularly fiberoptic bronchoscopy gerontal patient is more common, systemic physiological function reduces, often may merge multiple underlying diseases, the tolerance of anesthesia or operation is reduced.Under these often make Trachea Surface Anesthesia, fiberoptic bronchoscopy is forced to interrupt, or patient also can be made to be ready, and accepting secondary stock bronchoscopy inspection rate obviously reduces, thus also reduces quality and the safety of fiberoptic bronchoscopy.Now along with living standards of the people improve day by day, people are also more and more higher to medical demands, more and more wish to have comfortable safety and the medical environment of no pain and technology.
More and more advocate the painless Fibro-bronchoscopy test of row in developed countries such as Europe and the U.S., obtain the accreditation of extensive patients and scope doctor.As everyone knows, the anesthesia of painless fiberoptic bronchial endoscopy is the difficult problem being difficult to most in the anesthesia of all endoscopies capture always.Patients with respiratory tract is occupied, for anesthesia oxygen supply brings difficulty due to during bronchoscopy.In anesthesia, large more options retain patient's autonomous respiration, but the regulation and control of depth of anesthesia are very harsh, anaesthetizes shallowly not have anesthetic action and even make airway spasm occur, anaesthetize deeply then suppression breathing and cause anoxic blue spell.Especially gerontal patient's heart, pulmonary function are poor, and preoperative complication is many, and airway management difficulty, often occurs asphyxia, severe depletion of oxygen in art, and even need to interrupt operation and carry out assist or controlling breathing, patient safety is poor, and patient operates and is often affected.Adopt following several anesthesia to carry out the inspection of branchofiberoscope at present clinically: local anesthesia, balanced anesthesia, laryngeal mask airway general anesthesia numb through tracheal intubation whole body, but above method well solves bronchoscope yet and anesthesia shares gas to problem more.
Utility model content
The purpose of this utility model solves above-mentioned painless bronchoscope and the defect of anaesthetizing common-use tunnel, for bronchoscopy provides a kind of safe ready, can connect the bronchoscopy Special endotracheal tube of jet ventilator ventilation.
This utility model is achieved by the following technical solution:
A kind of bronchoscopy Special endotracheal tube, comprise main gas tube body, main gas tube body upper end is bronchoscopy connection tube joint, main gas tube body lower end is that the low pressure height be arranged on main gas tube body holds cylinder leakproof cuff, the gas injection joint with one-way cock is connected to by air injection pipe, main gas tube body upper end outer side edges has one to enter inside main gas tube body and is close to the fine duct that inner side comes downwards to leading body lower edge opening, and the outside of this fine duct upper end is for connecting jet ventilator.
The beneficial effects of the utility model are: bronchoscopy Special endotracheal tube structure is simple, reasonable in design, with low cost, after adopting appeal structure, after endotracheal tube inserts trachea, namely fine duct can connect jet ventilator ventilation, ventilation fine duct walks in endotracheal tube wall by the present invention, less on the impact of endotracheal tube caliber sectional area, have no effect to bronchoscopy, the present invention has started the new technique of painless Fibro-bronchoscopy test, has clear and definite social meaning and medical value.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 main gas tube body, 2 bronchoscopy connection tube joints, 3 fine ducts, 4 leakproof cuffs, 5 air injection pipe, 6 gas injection joints
Detailed description of the invention
For disclosing the technical solution of the utility model further, describe in detail below in conjunction with Figure of description.
Accompanying drawing 1 is a kind of specific embodiment of the present utility model.A kind of bronchoscopy Special endotracheal tube of this utility model, comprise main gas tube body 1, main gas tube body upper end is bronchoscopy connection tube joint 2, main gas tube body 1 lower end is that the low pressure height be arranged on main gas tube body 1 holds cylinder leakproof cuff 4, the gas injection joint 6 with one-way cock is connected to by air injection pipe 5, main gas tube body 1 upper end outer side edges has one to enter inside main gas tube body 1 and is close to the fine duct 3 that inner side comes downwards to leading body lower edge opening, and the outside of this fine duct 3 upper end is for connecting jet ventilator.
Further, described bronchoscopy connection tube joint 2 be international bore, be convenient to various model branchofiberoscope and enter, after leakproof cuff 4 gas injection, can prevent oral secretion from flowing into.
Further, the material of described leak-proof air bag 4 is polymer composite is high resiliency, have good retractility.
Further, described fine duct 3 walks in main gas tube body 1 inwall, and its lower ending opening is positioned at most lower edge.
A kind of bronchoscopy Special endotracheal tube of this utility model, main gas tube body 1 upper end is bronchoscopy connection tube joint 2, can insert branchofiberoscope through this pipe during use and carry out lower respiratory tract inspection, now caning be passed through main gas tube body 1 upper end outer side edges has one to enter inside main gas tube body 1 and is close to the fine duct 3 that inner side comes downwards to leading body 1 lower ending opening and connect jet ventilator mechanical ventilation.
This utility model is not limited to above-mentioned embodiment, anyone should learn make under enlightenment of the present utility model with this utility model, there is identical or close technical scheme, all fall within protection domain of the present utility model.
Technology, shape, structure part that this utility model is not described in detail are known technology.
