Two-way intubation tracheotomy dilating device with intubation channel

Abstract

The invention relates to the field of medical instruments, in particular to a two-way intubation tracheotomy dilating device with an intubation channel. The two-way intubation tracheotomy dilating device comprises a spiral dilator, a rotary knob, a puncture needle, a pressure spring, a buffer spring, a fixing rope, a catheter I, a guide wire, a catheter II, a ball bag, a ball bag airway tube, a pressure maintaining one-way valve and a sealing cap. In the two-way intubation tracheotomy dilating device, the elastically-triggered puncture needle is arranged at the bottom end in the spiral dilatorand can quickly extend out of the bottom end of the spiral dilator after being triggered to puncture the neck skin and the trachea wall of a trachea to form an opening. The upper end face to the interior of the spiral dilator are both designed to be hollow, catheter passing holes are formed in the two symmetrical sides of a threaded area of a lower-section conical face correspondingly, and thus the catheters can be allowed to pass to enter the trachea. Through the design that the two catheters are inserted in the trachea in the neck in the two ways, closed spaces are formed in the upper section and the lower section of the trachea in a neck incision correspondingly, the situation that a ball bag catheter is inserted in the mouth of a patient for filling of the upper end of the incision trachea is not needed, and thus operation is simplified.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bidirectional intubation tube tracheotomy dilation device with an intubation channel. Background technique [0002] A tracheostomy is an emergency procedure initially reserved for relieving breathing difficulties caused by laryngeal obstruction. With the in-depth understanding of the pathophysiological function of the respiratory tract, tracheotomy has become an important adjuvant treatment for certain diseases. For example, in comatose patients for a long time caused by various reasons, the accumulation of secretions in the lower respiratory tract will affect the lung ventilation function. Drugs and antibiotics for viscous secretions to prevent or treat pulmonary complications. After tracheotomy, air enters directly from the incision, which reduces the resistance and dead space of the respiratory tract. Under the same tidal volume, it can not only increase the effective gas ex...

AI Technical Summary

Problems solved by technology

The operation is very cumbersome, and the repeated insertion and removal of oxygen tubes and the establishment of channels are very tormenting for patients

The traditional intermediate tracheostomy lacks a buffer transition stage that can detect and try the patient's nasal breathing

[0005] 2. The traditional tracheotomy can only provide breathing for the patient by connecting the oxygen tube at the intubation site. The upper part of the tracheotomy to the nasal cavity is always blocked by a balloon, and it is impossible to breathe through the nasal cavity.

After sputum suction and other treatments, the tracheal obstruction decreases. When the endotracheal intubation balloon is not withdrawn, the patient cannot breathe through the nasal cavity. It is necessary to connect the oxygen tube at the endotracheal intubation site, which cannot be withdrawn for the patient. Oxygen tube lost, self-activity during the recovery period of mouth and nose spontaneous breathing is very inconvenient

[0006] 3. In the traditional tracheotomy, after the tracheotomy, a balloon catheter is inserted to seal the lower trachea, and at the same time, a balloon catheter needs to be inserted through the patient's mouth to seal the upper trachea of ​​the incision to form an airtight effect, which is cumbersome to operate , and a fixer needs to be fixed in the patient's mouth to fix the catheter inserted in the mouth, and the operation is very cumbersome

And the balloon catheter always exists during the process of endotracheal intubation, so that the patient's mouth is always open and the balloon catheter is inserted, and the physiological vomiting reaction of foreign objects inserted in the pharynx is very painful for the patient

[0007] 4. There is no channel for tracheal intubation inside the traditional helical dilator. After the helical dilator is withdrawn, it is necessary to clamp and pull the incision with multiple expansion forceps to ensure the expansion state of the incision. The operation is very cumbersome, and the expansion forceps It is very easy to slip in the neck when it is pulled out, causing the incision to expand and remain unstable, which is not conducive to the doctor's tracheal intubation

Moreover, this operation requires the cooperation of multiple doctors, which takes up the manpower of doctors and is inefficient.

[0008] 5. In the traditional tracheal intubation operation, the tracheostomy intubation needs to be manually supported and fixed by the doctor when it is inserted from the incision to the trachea in the neck, which also takes up the manpower of the doctor and reduces the efficiency of treatment.
