Technical Field

The utility model relates to an improved disposable open airway pipeline device, and belongs to the technical field of medical instruments.

Background

Clinically, patients with dyspnea often need to open the airway in time and continue to aspirate sputum or ventilate to keep the airway patent. The existing commonly used pipeline of the open airway is provided with an oropharyngeal airway and an airway intubation tube, the time for placing the oropharyngeal airway is short, but the oropharyngeal airway can not effectively remove the airway obstruction, and sometimes the oropharyngeal airway needs to be matched with a sputum suction tube for use; the tracheal cannula can fully remove the airway obstruction, but has long tube setting time. They all have respective advantages and disadvantages, and the pre-hospital first aid should be flexibly selected according to the specific situation of the patient. However, in clinical work, it is found that the oral mucosa of a patient is damaged when an oropharyngeal airway or an endotracheal tube is placed (penmen have suffered from the fact that the throat wall of the patient is damaged by instruments during placement of the endotracheal tube, so that huge blood bubbles are generated), and for critical patients, the damage can aggravate infection of the patient (particularly patients with blood coagulation dysfunction).

Detailed Description

The utility model is further illustrated by the following specific figures and examples.

As shown in fig. 1 to 3, the embodiment discloses an improved disposable open airway pipeline device, which includes a pipeline body 1, wherein the pipeline body 1 is made of rigid plastic, the front end of the pipeline body 1 is an insertion end for inserting an airway, the rear portion of the pipeline body 1, which is far away from the insertion end, is a main body section 1a, a section of a small-diameter section 1b with a reduced inner diameter and outer diameter is arranged at the front portion of the pipeline body 1, which is close to the insertion end, a transition portion between the small-diameter section 1b and the main body section 1a is a slope-shaped structure 1c with an inner diameter gradually reduced from back to front and then gradually increased, and a flexible silica gel sleeve 2 is coated outside the small-diameter section 1 b.

In the present embodiment, as shown in fig. 2 and 3, the outer diameter of the small diameter section 1b gradually increases from the rear end to the front end, and the inner diameter of the flexible silicone sleeve 2 gradually decreases from the rear end to the front end. By such an arrangement, the flexible silicone sleeve 2 can be more firmly and reliably bonded on the small-diameter section 1 b.

As shown in fig. 3, in the present embodiment, a plurality of semi-annular ribs 1d parallel to each other are disposed on the outer surface of the small-diameter section 1b, and the adjacent semi-annular ribs 1d are distributed in a staggered manner in the circumferential direction; the inner surface of the flexible silica gel casing 2 is provided with a plurality of semi-annular grooves 2a which are correspondingly matched with the semi-annular convex ribs 1d one by one. So set up, through mutually supporting of the protruding muscle 1d of semicircular ring shape and semicircular groove 2a, can prevent on the one hand that flexible silica gel sleeve pipe 2 from taking place the axial float on thin footpath section 1b, on the other hand can prevent again that flexible silica gel sleeve pipe 2 from taking place circumferential direction, promotes the firm degree that flexible silica gel sleeve pipe 2 is fixed comprehensively.

As shown in fig. 2 and 4, in this embodiment, an annular positioning shoulder 2b is disposed on an inner edge of the front end of the flexible silica gel sleeve 2, and an inner side surface of the annular positioning shoulder 2b is tightly abutted to the front end surface of the pipeline body 1; the outer edge of the front end of the flexible silica gel sleeve 2 is arc-shaped. So set up, the pipeline body of stereoplasm is being wrapped up completely to the front end of flexible silica gel sleeve pipe 2 to can effectively reduce oral mucosa damage.

The pipeline body 1 can be an oropharyngeal airway or a tracheal cannula, and the damage to oral mucosa in the pipeline insertion process can be favorably reduced by adopting the structure.

The specific application of the utility model is as follows:

when pipeline body 1 is oropharynx breather pipe, make the patient put suitable position earlier, then inhale oral cavity and pharyngeal secretion, select suitable method of placing according to the condition again and put into the oral cavity with oropharynx breather pipe, then test whether unobstructed of artificial air flue, prevent that tongue or lip from pressing from both sides between tooth and oropharynx breather pipe. Because the thin neck section outside cladding of oropharynx breather pipe has flexible silica gel sleeve pipe 2, can significantly reduce oropharynx breather pipe and mucosa damage in the contact process of mucosa like this. When the patient need inhale the phlegm, get and inhale the phlegm pipe, connect negative pressure device, will inhale the phlegm pipe and insert and inwards impel from the rear end of oropharynx breather pipe, because the transition position between thin footpath section 1b and the main part section 1a on the pipeline body 1 is slope shape structure 1c to can avoid inhaling the phlegm in-process and take place to inhale the stuttering of phlegm pipe. When the pipeline body 1 is a trachea cannula, the existing conventional method is still adopted in the tube placing method, but the flexible silica gel sleeve 2 can greatly reduce the oral mucosa injury.

The above description is only for the preferred embodiment of the present invention, and the above specific embodiments are not intended to limit the present invention. Various modifications and alterations may occur to those skilled in the art without departing from the spirit and scope of the utility model, and such modifications and alterations should be accorded the broadest interpretation so as to encompass all such modifications and alterations.
