Further, the second mark line 9 is a red bold mark line.
The sputum suction method for the lower respiratory tract in the design adopts the following steps:
the method comprises the following steps: when the sputum suction tube is inserted into the nose or the mouth, the inward-bending side (namely the black radial marking line) is kept towards the foot end, and the negative pressure suction is carried out at proper time until the head end of the sputum suction tube reaches the oropharynx part;
step two: when the head end is positioned at the oropharynx part, the sputum suction tube is rotated by 180 degrees, the inward bend is backwards faced, and the front end of the sputum suction tube reaches the laryngopharynx and is positioned at the rear and lower positions of the epiglottis in cooperation with short-time negative pressure suction;
step three: when the head end is at the laryngopharynx part, the sputum suction tube is rotated by 180 degrees again, the inward bend side is forward, and the front end of the sputum suction tube strides over the intersubular area and the arytenons of the arytenons by matching with short-time negative pressure suction, enters the glottis and reaches the main trachea.
The working principle of the utility model is as follows:
1. the head end of the sputum suction pipe is hemispherical, the top end is a blind end, a sputum suction hole is not formed, stimulation and damage to mucosa in the sputum suction process of the head end are reduced, and silica gel is selected as a material.
2. Inhale the phlegm pipe head end and be crooked form, length 2.0cm, head end bent part 2 is certain contained angle with the straight part 7 of main part, and the angle is 150, and the skew pipe shaft axis of ordinates in top 1cm, and establishes the second at crooked initial part and below and inhale phlegm hole, first phlegm hole of inhaling, and the straight part of main part sets up the third and inhales the phlegm hole, and the material chooses for use polyvinyl chloride (PVC) that toughness is better.
3. The sputum suction tube keeps certain hardness, can drive the front end bending part to rotate together at least when rotating 17-20 cm away from the head end, and can not be twisted in an air passage because of the viscosity of sputum, if the direction of entering left and right bronchi is required to be controlled on the trachea carina layer, the toughness of the sputum suction tube is properly enhanced.
4. At the beginning of inward bending of the head end of the sputum aspirator, black radial marking lines are marked on the longitudinal axis, scales are marked on the lines (at least 5cm marks a numerical value), and the radial marking lines between 13cm and 17cm away from the head end are set to be red and thickened (marking line II 9).
The design takes nasal sputum suction as an example, and states that the sputum suction operation method is carried out by utilizing a sputum suction pipe:
a. after the sputum suction pipe extends into the nasal vestibule, keeping the incurved side downward, sucking at a proper negative pressure, and keeping the sputum suction pipe to move forward in the lower nasal passage;
b. when the front end of the sputum suction tube reaches the oropharynx (when the entering length is set to be 13 cm), the sputum suction tube is rotated by 180 degrees to enable the inward-bent side to face backwards, negative pressure suction is carried out for a short time if necessary, the round head front end is kept to be attached to the rear wall of the pharynx to reach the laryngopharynx, and the front end of the sputum suction tube is prevented from entering the epiglottis valley;
C. after entering the laryngopharynx (when the entering length is set to be 17 cm), the sputum suction tube is rotated by 180 degrees again to enable the inner curved surface to move forwards, and negative pressure suction is performed for a short time if necessary so as to facilitate the suction of sputum above the glottis and the entry of the sputum suction tube into the glottis and the arrival of the main trachea;
d. the sputum suction tube enters the trachea, before reaching the carina, the sputum suction tube is rotated by 90 degrees and is sucked under negative pressure in due time, so that the sputum suction tube is favorably attached to the left side or the right side wall of the trachea, and the sputum suction tube selectively enters the left main trachea or the right main trachea according to the will of a sputum aspirator.
Because the trachea is positioned at the right front of the esophagus at the throat part, the sputum suction tube is recommended to enter from the right nostril, and before the sputum suction tube enters into the glottis and the main trachea, the operator holds the sputum suction tube part, the right nostril and the laryngeal prominence to be best on the front middle sagittal plane of a patient.
The sputum suction tube of the design has the following use and operation processes in realizing the sputum suction of the lower respiratory tract:
(1) as shown in figure 2, after the suction catheter is inserted into the nasal vestibule, the inturned side (namely the black radial mark line) is kept towards the foot end, and the suction catheter is sucked under negative pressure at proper time and kept to move forward in the lower nasal passage until reaching the nasopharynx part.
(2) When the suction tube reaches the oropharynx (when the suction tube reaches the nasal tip at a position 13cm away from the head end 8), the suction tube is rotated by 180 degrees to enable the inward-curved surface to be backward at the oropharynx (namely, the black radial marking line is backward, and the outward observation of the nasal tip is namely towards the head end), if necessary, negative pressure suction is performed for a short time, the front end of the round head is kept to be attached to the rear wall of the pharynx to reach the laryngopharynx, and the front end of the suction tube is prevented from entering the epiglottis valley before the epiglottis and behind the tongue root, as shown in figure 3.
(3) After entering the laryngopharynx, the front end of the sputum suction tube is positioned at the rear and lower positions of the epiglottis, when the sputum suction tube reaches the nasal tip at a position 17cm away from the head end by 10, the sputum suction tube is rotated by 180 degrees again, so that the inward-bending side is forward (namely the black radial marking line is forward, and the line is toward the foot end when the nasal tip is observed outward), as shown in fig. 4; when necessary, the negative pressure suction is performed for a short time so as to be beneficial to sucking and removing sputum above the glottis and to be beneficial to the suction tube to cross the intersubular area and the arytenons of the arytenons so as to avoid mistakenly entering the esophagus, and the suction tube enters the glottis and reaches the main trachea, as shown in figure 5.
(4) The sputum suction tube continues to move forwards downwards after entering the trachea, before reaching the carina, the sputum suction tube is rotated by 90 degrees leftwards or rightwards, and then is sucked under negative pressure at proper time, so that the sputum suction tube is favorably attached to the left side wall or the right side wall of the trachea, and then selectively enters the left main trachea or the right main trachea according to the desire of a sputum aspirator, as shown in fig. 6 and 7.
After the structure is adopted, the utility model discloses beneficial effect does: a sputum aspirator for lower respiratory tract, it not only can effectively aspirate the secretion of upper and lower respiratory tract, can reduce simultaneously and inhale the sputum aspirator and irritate patient, reduce the emergence that the mucosa bleeded, alleviate the misery that the sputum aspirator brought.
The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
