Abstract
The utility model provides a late-model tracheal catheter that prevents retention of cystic secretion and is characterized in that the bent lateral side in the middle part and the upper part of a catheter body is provided with an irrigating catheter with the bigger caliber than that of the bladder catheter; the irrigating catheter paralleling with the bladder catheter in the internal body, penetrates through the pipe wall above the bladder 1-2 cm and encircles the catheter body above the bladder. The utility model has practicable operation and obvious effect, thereby, relieves the patients from pain and improves the cure rate.
Description
Technical field
This utility model relates to a kind of medical instruments, the endotracheal tube that secretions is detained on the particularly anti-capsule.
Background technology
When using the respirator rescue to carry out the patient of mechanical ventilation, the most frequently used respirator and patient's connected mode are per nasal or orotracheal tube intubate or tracheotomy insertion endotracheal tube.Loosening for preventing gas leakage and endotracheal tube, be an air bag at the front end of endotracheal tube, capsule is inflated after inserting endotracheal tube, make between itself and tracheal wall airtight.Because of air bag top airless passes through, the reason of position in addition, almost each patient has all that secretions is detained on the capsule.And the secretions that is detained is difficult to remove with conventional method.When pulling out the replacing endotracheal tube or being interrupted the air bag emptying for the damage of minimizing tracheal wall, the secretions that is detained flows into lower respiratory tract along tracheal wall, cause or increase the weight of pulmonary infection, Mechanical ventilation time is prolonged, hospitalization cost increases even respirator relies on and patient death.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiencies in the prior art, and a kind of secretions on the capsule of being convenient to wash is provided, and reduces patient's misery and financial burden, the endotracheal tube that secretions is detained on the novel anti-capsule easy to use.
The purpose of this utility model is achieved in that
The endotracheal tube that secretions is detained on a kind of anti-capsule, the air bag 2 that comprises catheter main body 1 front end, air bag airway 3 and bandage fixed cover 4, it is characterized in that irrigating catheter 5 is introduced in side, curved position in the catheter main body middle and upper part, its caliber is greater than air bag airway 3, be parallel to catheter main body inside with air bag airway 3, the 1-3cm place passes tube wall above air bag 2, in top ring one week of catheter main body of air bag.
---on the outer wall of the catheter main body of described irrigating catheter 5 belows the sulculus spline structure is arranged, have the partial flushing conduit to be positioned at sulculus.
---outer irrigating catheter 5 ends of described catheter main body wall have several side openings 9, and the rinse mouth of irrigating catheter 5 has the capping plug 6 that can seal the mouth of pipe.
This utility model is practical through clinical trial certificate, and effect is fine, has removed the many miseries of patient, has improved more rate of doctor greatly.
Description of drawings
Fig. 1 is the cutaway view of this utility model endotracheal tube that trachea inserts under larynx.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is this utility model per nasal or mouthful endotracheal tube cutaway view that inserts.
In Fig. 1 to Fig. 3,1 is catheter main body, and 2 is air bag, and 3 is the air bag airway, and 4 is the bandage fixed cover, and 5 is irrigating catheter, and 6 is capping plug, and 7 for connecing the respirator mouth, and 8 is charging valve, and 9 is side opening.
The specific embodiment
Select suitable medical catheter 1, make its lower end pass air bag 2,, open the mouth of an insertion air bag airway 3 on the top of conduit, it is inserted in air bag along inside pipe wall, be sealed in air bag again the contact portion sealing.In the upper port of air bag airway charging valve is arranged, valve open during inflation charges air valve and closes.Open an aperture in side, curved position, pipe 1 upper end, insert syringe pipe 5, caliber is about a times of air bag airway, parallel with balloon catheter, the 1.5cm place passes tube wall above air bag, and diagonal is downward, in top ring one week of conduit of air bag, the sulculus spline structure is arranged on the conduit outer wall below the irrigating catheter 5, and some is positioned at sulculus irrigating catheter, comes off to prevent the irrigating catheter 5 outside the excessive and duct wall of in intubate process friction.The outer irrigating catheter end of tube wall has side opening 9, avoids plugging.The inlet of irrigating catheter is established the little plug 6 that seals, and when not carrying out the secretions flushing, seals the mouth of pipe, in order to avoid the invasion of antibacterial and microorganism.
During with this utility model intubate, need regularly wash secretions on the capsule.Because secretions is often than thickness, and the syringe pipe caliber is less,, can carry out synchronously with suction expectorant so flushing blanking time can not be long.
Claims (3)
