Abstract
The utility model provides a high-frequency jet tracheal tube, and belongs to the technical field of medical instruments. The high-frequency jet tracheal tube adopts the structure that the high-frequency jet tracheal tube comprises a tracheal tube; an interface is arranged at the remote end of the tracheal tube, and an air pocket is arranged at the proximal end thereof; the conduit of the air pocket is laid along the outer wall of the tracheal tube and is connected with the air pocket; both a jet conduit and an air pressure detection conduit penetrate from tube wall at the remote end of the tracheal tube into the tracheal tube, are laid along the inner wall of the tracheal tube, and communicated to the proximal end of the tracheal tube; and a jet nozzle is arranged at the proximal end of the jet conduit. As the high-frequency jet tracheal tube is provided with an air flue inner peak pressure and an air flue inner mean pressure, the utility model can reduce interference to a cardiovascular system and reduce pressure injury to a lung, is usually used in a clinical fiberoptic bronchoscope examination on a patient needing breathing support, and has obvious effect on the patient needing breathing support.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of high-frequency jet endotracheal tube.
Background technology
General, high frequency ventilation is a kind of form of mechanical ventilation, is the tidal volume of using less than anatomical dead space, high ventilatory frequency is ventilated.High frequency ventilation has just begun application as far back as early 1970s.Up to now, the existing nearly 20 years history of the clinical practice of high frequency ventilation.The domestic clinical report of using high frequency ventilation in recent years also day by day increases.Department of pediatrics is mainly used in the treatment of neonate severe respiratory failure, is particularly useful for the premature infant of the severe respiratory failure of the high positive airway pressure of need.But the technology of high-frequency jet endotracheal tube also is not very ripe, and some needs further to improve at human body technical ability or disease on structural design.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of high-frequency jet endotracheal tube is provided.
The technical solution of the utility model realizes in the following manner, this high-frequency jet endotracheal tube, its structure comprises endotracheal tube, the far-end of endotracheal tube is provided with interface, the near-end of endotracheal tube is provided with air bag, and balloon catheter lays with air bag along the outer wall of endotracheal tube and is connected, and fluidic conduit and air pressure detected catheter penetrate in the pipe from the far-end tube wall of endotracheal tube respectively, lay the near-end that is communicated to endotracheal tube along inside pipe wall, the fluidic conduit near-end is provided with nozzle.
Nozzle is positioned at one section middle part of the endotracheal tube that is provided with air bag.
The beneficial effect that this utility model is compared with prior art produced is:
This high-frequency jet endotracheal tube, have peak pressure and the interior mean pressure of air flue in the low air flue, can alleviate the pressure damage of cardiovascular system being disturbed and reduces lung, when the clinical patient who is usually used in needs breathing support did bronchoscopy, bronchus patient's effect that ventilation is supported to needs was remarkable.
This high-frequency jet endotracheal tube is compared the high frequency ventilation superiority and mainly is to reduce pressure oscillation in the air flue with conventional mechanical ventilation, make lung be in even inflation and suitable capacity state because of raising more alveolar during high frequency ventilation, leak and chronic lung disease so reduced mechanical ventilation process a middle or short term and long-term complications such as gas.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Labelling in the accompanying drawing is represented respectively:
1, endotracheal tube, 2, interface, 3, balloon catheter, 4, air bag, 5, fluidic conduit, 6, the air pressure detected catheter, 7, nozzle.
The specific embodiment
Below in conjunction with accompanying drawing high-frequency jet endotracheal tube of the present utility model is done following detailed description the in detail.
As shown in Figure 1, high-frequency jet endotracheal tube of the present utility model, its structure comprises endotracheal tube 1, the far-end of endotracheal tube 1 is provided with interface 2, the near-end of endotracheal tube 1 is provided with air bag 4, and balloon catheter 3 lays with air bag 4 along the outer wall of endotracheal tube 1 and is connected, and fluidic conduit 5 and air pressure detected catheter 6 penetrate in the pipe from the far-end tube wall of endotracheal tube 1 respectively, lay the near-end that is communicated to endotracheal tube 1 along inside pipe wall, fluidic conduit 5 near-ends are provided with nozzle 7.Nozzle 7 is positioned at one section middle part of the endotracheal tube 1 that is provided with air bag 4.
This high-frequency jet endotracheal tube in use, use the high-voltage power supply driving gas, directly the fast gas of altofrequency, low tidal volume is sprayed in infant air flue and the lung by special multi-cavity tracheal intubation by high-frequency electromagnetic valve, control damper, pressure-regulating valve and nozzle.The ventilatory frequency of high-frequency jet is 60～600 times/min (1～10Hz).
Claims (2)
1, high-frequency jet endotracheal tube, comprise endotracheal tube, the far-end of endotracheal tube is provided with interface, the near-end that it is characterized in that endotracheal tube is provided with air bag, balloon catheter lays with air bag along the outer wall of endotracheal tube and is connected, fluidic conduit and air pressure detected catheter penetrate in the pipe from the far-end tube wall of endotracheal tube respectively, lay the near-end that is communicated to endotracheal tube along inside pipe wall, and the fluidic conduit near-end is provided with nozzle.
2, high-frequency jet endotracheal tube according to claim 1 is characterized in that nozzle is positioned at one section middle part of the endotracheal tube that is provided with air bag.
