Abstract

A special sputum suction tube for a trachea cannula is characterized in that a hard tube is mounted at one end of a cavity connecting seat, an outflow joint is mounted at the other end of the connecting seat, a control hole is arranged on one lateral wall of the connecting seat, an initial section and an end section of the hard tube are in the shapes of straight tubes, a middle section of the hard tube is in a curved shape, attracting holes are arrange on the lateral walls of two opposite surfaces of the end section, and the tip of the end section is a hemispherical blind end. The special sputum suction tube solves the problem of difficult control of cleaning secretions such as foreign matters, sputum and the like inside an oval cavity, a pharynx, a larynx and a trachea, and is applicable to use for cleaning the foreign matters, the sputum and the secretions inside the oval cavity, the pharynx, the larynx and the trachea when in trachea cannula.

Description

Dedicated suction catheter for trachea cannula

Technical field

This utility model relates to medical instruments field, a kind of sputum aspirator tube of foreign bodies such as cleaning oral cavity, bottleneck throat, intra-tracheal sputum liquid when being used for tracheal intubation specifically.

Background technology

Tracheal intubation is the common technology of first aid, cardio-pulmonary resuscitation, general anesthesia, must clear up oral cavity, bottleneck throat, intratracheal foreign body, sputum, secretions during intubate, at present, still do not have special-purpose sputum aspirator tube clinically, all adopt straight shape flexible pipe to carry out, its shortcoming is that direction is wayward, be difficult for crossing the pharyngeal cavity that is arcuation, can't for tracheal intubation makes troubles, the success rate of tracheal intubation and the success rate of rescue have been influenced to clearing up in the trachea.

The utility model content

This utility model adopts flexible pipe cleaning oral cavity, bottleneck throat, intra-tracheal sputum liquid direction wayward when solving present tracheal intubation operation, has influenced the success rate of tracheal intubation and the success rate problem of rescue, designs the special-purpose hardware sputum aspirator tube of a kind of tracheal intubation.

The technical solution adopted in the utility model is, a kind of dedicated suction catheter for trachea cannula, its special character be, at an end of cavity coupling seat hard tube is housed, and the other end of coupling seat is equipped with outer stream interface, has control hole on the sidewall of coupling seat; First section of hard tube and latter end are straight tube-like, and the stage casing is the curved arc shape; Have the attraction hole on the sidewall on the relative two sides of latter end, the termination of latter end is the hemispherical cecum.

The partly about 260mm of first section stretched of hard tube, the angle of stage casing curved body is about 35 °, the about 60mm of radius of the radian, the about 30mm of arc length, latter end is about 30mm.

During use, outflow port on the coupling seat is connected to tracheal intubation suction pump pipeline, the right hand is held coupling seat, left hand is held laryngopharyngeal mirror, under expressing, laryngopharyngeal mirror appears glottis and epiglottis, the termination is crossed glottis and is entered in the trachea, because the termination is the semispherical surface slyness, can be in the attraction scale removal process thereby guaranteed to the bottleneck throat mucosa, tracheal wall causes damage, the root of the tongue is curved to glottis, the curved arc of hard tube has guaranteed that the termination enters under the glottis in the trachea smoothly, during attraction, covers control hole on the coupling seat with hand thumb, unclamp hand thumb frequently or not exclusively unclamp hand thumb, with flexible control suction size, sputum, secretions, foreign bodies etc. enter hard tube by the attraction hole of termination double side wall, get rid of through the coupling seat outflow port.

Technique effect of the present utility model is, adopt technique scheme can realize that a kind of hard easily crosses pharyngeal cavity, the manageable dedicated suction catheter for trachea cannula of direction, it can be cleared up oral cavity, bottleneck throat, intratracheal foreign body, sputum, secretions effectively, and to tracheal wall, bottleneck throat mucosa not damaged.

Description of drawings

Fig. 1 is a structural front view of the present utility model, and as Figure of abstract.

In the drawings, 1 coupling seat, 2 control holes, 3 hard tubes, 4 curved arcs, 5 latter ends, 6 terminations, 7 attract hole, 8 outflow port.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is further specified.

As shown in the figure, at an end of cavity coupling seat 1 hard tube 3 is housed, the other end of coupling seat 1 is equipped with outer stream interface 8, has control hole 2 on the sidewall of coupling seat 1; First section of hard tube 3 and latter end are straight tube-like, and the stage casing is curved arc 4 shapes; Have attraction hole 7 on the sidewall on the relative two sides of latter end 5, the termination 6 of latter end 5 is the hemispherical cecum.

During use, outflow port on the coupling seat 18 is connected to the suction pump pipeline, the right hand is held coupling seat 1, left hand is held laryngopharyngeal mirror, under expressing, laryngopharyngeal mirror appears glottis and epiglottis, termination 6 is crossed glottis and is entered in the trachea, because the termination is the semispherical surface slyness, can be in the attraction scale removal process thereby guaranteed to the bottleneck throat mucosa, tracheal wall causes damage, the root of the tongue is curved to glottis, the curved arc 4 of hard tube 3 has guaranteed that termination 6 enters under the glottis in the trachea smoothly, attracts, during cleaning, cover the control hole 2 of coupling seat 1 sidewall with hand thumb, unclamp hand thumb frequently or not exclusively unclamp hand thumb, with flexible control suction size, sputum, secretions, foreign bodies etc. enter hard tube 3 by the attraction hole 7 of termination 6 double side walls, get rid of through the outflow port 8 of coupling seat 1.

Claims

1. dedicated suction catheter for trachea cannula, it is characterized in that: the end in the cavity coupling seat is equipped with hard tube, and the other end of coupling seat is equipped with outer stream interface, has control hole on the sidewall of coupling seat; First section of hard tube and latter end are straight tube-like, and the stage casing is the curved arc shape; Have the attraction hole on the sidewall on the relative two sides of latter end, the termination of latter end is the hemispherical cecum.
