Quick puncture ventilation kit for cricothyroid membrane
Technical Field
The invention relates to medical equipment for emergency treatment, in particular to a cricothyroid membrane rapid puncture ventilation kit applied to emergency treatment of acute upper respiratory tract obstruction.
Background
In clinic, acute laryngeal edema, acute epiglottis or edema of the gap in front of the epiglottis, head and neck or throat trauma, head and neck tumor, difficult intubated tracheal cannula obstruction of general anesthesia patients or glossolalia postoperation tongue root falling and the like are all easy to cause acute upper respiratory tract obstruction, if not treated in time, suffocation death of patients can be caused in a short time. In emergency treatment, it is often necessary to perform cricothyroid puncture and then take measures to rapidly open the airway such as emergency endotracheal intubation, tracheotomy or cricothyroid incision. At present, the clinical treatment of acute upper respiratory obstruction is carried out by puncturing the cricothyroid membrane by directly puncturing the cricothyroid membrane by using a large-size syringe needle, so that the airway is communicated with air, however, only 21% of oxygen in the air of a patient can be provided by doing so, the needle cannot be fixed, and the needle is easy to fall off or puncture the airway and surrounding tissues along with agitation of the patient, so that serious complications are caused.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
As shown in fig. 1, 2 and 3, the product kit of the present invention comprises a puncture needle assembly, a ventilation inner sheath assembly, a fixing balloon assembly, the ventilation inner sheath assembly being arranged on the outer layer of the puncture needle assembly, and the fixing balloon assembly being arranged on the outer layer of the ventilation inner sheath assembly. The puncture needle assembly comprises a puncture needle 1 for puncturing a cricothyroid membrane and a puncture needle handle 2 which can be screwed off, and the ventilation inner sheath assembly comprises a ventilation inner sheath 7 and a standard breathing end connecting port 3 which is used for being connected with a breathing machine or a simple breathing air bag for ventilation. The fixed balloon assembly comprises a balloon pushing outer sheath 8, a sliding balloon pushing handle 4 for pushing and retracting the balloon, an outer fixed balloon 5 for fixing the ventilation inner sheath outside the skin so as not to slide into the airway further, and an inner fixed balloon 6 for fixing the ventilation inner sheath inside the airway so as not to deviate from the skin. According to the technical scheme, the inner fixing saccule and the outer fixing saccule can fix the ventilation inner sheath not to slide into the deep part of the airway or to deviate from the airway, so that complications in the rescue process can be reduced, and the standard respiratory end connecting port 3 can be connected with a breathing machine and a simple respiratory air bag.
Compared with the prior art, the invention has the following advantages:
1) The product kit has compact and ingenious overall design structure, flexible, convenient and safe operation, is directly processed and formed during production, and is packaged into a disposable product after being sterilized and disinfected by ethylene oxide.
2) In the product kit, the ventilation inner sheath and the standard respiratory end connector can be directly connected with respiratory support equipment such as a respirator, a simple respiratory air bag and the like to provide 100% pure oxygen for a patient, so that the recovery of the later respiratory function of the patient is facilitated;
3) In the product kit, the internal fixing saccule is used for fixing the ventilation inner sheath in the airway so that the ventilation inner sheath cannot slip out of the body; the external fixing saccule is used for fixing the ventilation inner sheath on the surface of the skin so that the ventilation inner sheath cannot slide into the far end of the airway, and therefore complications are reduced. And the ventilation inner sheath is fixed by adopting the inner and outer fixing balloons with self-expanding umbrella-shaped structures, so that the ventilation process is safe and simple. And a sliding balloon pushing handle is designed, and the handle is positioned at the tail end of the balloon pushing rod and is arranged on the balloon pushing outer sheath 8. The pushing handle can freely slide for self-expansion and contraction of the inner and outer fixed balloons, the structure is compact and ingenious, the operation is flexible, convenient and safe, and the diameter of the inner and outer balloons after being folded is the same as the diameter of the balloon pushing sheath 8.
The application method of the product kit comprises the following steps:
1. patient position, patient takes supine position, leans back head, and the shoulder is put on the pillow to tighten the median ligament of the cricothyroid, which is beneficial to exposing anatomical marks. Rapidly sterilizing, spreading a sterile towel, and carrying out local injection anesthesia on 1-2 mL of 2% lidocaine. In emergency, the patient can take the semi-lying position or sitting position without anesthesia or sterile towel laying.
2. Determining the position of a cricothyroid membrane: when the head is bent backwards as much as possible, two bulges can be seen and contacted in the middle of the front neck, the upper part is a laryngeal knot and the front corner, the lower part is an annular cartilage arch, and the concave part between the two parts, namely the central ligament of the cricothyroid, is the correct part for puncture.
3. The operation method comprises the following steps: the nail cartilage and the cricoid cartilage are respectively fixed by the thumb and the index finger of the left hand, and the skin is slightly tightened, so that the median ligament of the cricoid is tensioned, and the puncture and the operation are facilitated. The puncture needle 1 and the puncture needle handle 2 are held by the index finger and the middle finger of the right hand, and a falling feel exists after the puncture needle enters the subglottal region along the central horizontal position of the cricothyroid membrane, namely, the puncture is successful, then a 0.3mm incision is cut at the joint of the puncture needle and the skin by using a blade, the puncture needle handle 2 is unscrewed, then the ventilation inner sheath 7 and the standard respiratory end connecting port 3 are inserted into the airway along the puncture needle 1, then the puncture needle 1 is withdrawn, the left hand fixing balloon pushes the outer sheath 8, the right hand slides the sliding balloon pushing handle 4 towards the balloon end, the inner fixing balloon 6 and the outer fixing balloon 5 are expanded, and the ventilation inner sheath 7 is fixed in the airway and on the skin so as to avoid the sheath tube from falling out. Then, the simple breathing air bag or the breathing machine can be directly connected through the standard breathing end connecting port 3, so that the breathing support is provided for the patient in the rescue of the acute upper respiratory obstruction.
In conclusion, the product kit disclosed by the invention is low in cost and convenient to popularize and apply in a large area in clinic.
