The sputum suction device has the advantages of reasonable design, simple structure and convenience in use, can prevent the respiratory tract inner wall from being damaged, and has better sputum suction effect.

Description

Ultra-smooth sputum suction tube

Technical Field

The utility model relates to a medical appliance, in particular to an ultra-smooth sputum suction tube.

Background

At present, a sputum suction tube used clinically has a single function, only has the function of sucking sputum, can realize comprehensive sputum suction on the inner wall of a respiratory tract only by matching the activity of the sputum suction tube during sputum suction, has poor sputum suction effect, and can cause discomfort to a patient and harm when the sputum suction tube moves or moves in the respiratory tract due to friction between the outer surface of the sputum suction tube and the inner wall of the respiratory tract. In addition, the head end of the sputum suction tube usually adopts a chamfer form, is relatively sharp, and is easy to scratch respiratory mucosa, thereby causing secondary injury to patients.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to prior art not enough, provide a reasonable in design, prevent to cause the damage to the respiratory track inner wall to inhale the superslide phlegm suction pipe that the phlegm effect is better.

The utility model aims to solve the technical problem that the realization is realized through following technical scheme, the utility model relates to a phlegm pipe is inhaled to super-smooth, should inhale the phlegm pipe and include the pipe, and the pipe front end is equipped with inhales the phlegm mouth, is close to be equipped with one pair of perforation on inhaling the pipe of phlegm mouth at least, and the pipe rear end is equipped with the opening, and the pipe joint is equipped with to the opening part, and the coating has hydrophilic coating on the pipe.

The technical problem to be solved by the utility model can also be realized by the following technical scheme, the coating length of the hydrophilic coating is 15cm-40cm from the sputum suction port to extend backwards, and the thickness of the hydrophilic coating is 1-2 mm.

The technical problem to be solved by the utility model can also be realized by the following technical scheme, the pipe is the PVC pipe of non-DEHP.

The utility model discloses the technical problem that will solve can also be realized through following technical scheme, the surface of pipe is equipped with the scale mark.

The utility model discloses the technical problem that will solve can also be realized through following technical scheme, be equipped with two pairs to the perforation, two are perpendicular to the fenestrate axis, the setting of staggering, and one of them is a pair of axis symmetry along the pipe sets up the both sides at the scale mark.

The utility model discloses the technical problem that will solve can also be realized through following technical scheme, be 1.1 +/-0.3 mm to fenestrate aperture.

The technical problem to be solved by the utility model can be realized by the following technical proposal, the sputum suction port is arranged obliquely, and the inclination angle is 45-70 degrees.

The utility model discloses the technical problem that will solve can also be realized through following technical scheme, pipe joint be equipped with the horn mouth of being connected with the vacuum aspiration machine.

Compared with the prior art, the utility model discloses a scribble hydrophilic coating at the pipe surface of inhaling the phlegm pipe, meet water inflation, insert breathe then the time resistance less, reduce the probability of bleeding, adopt the phlegm mouth of inhaling that the slope set up moreover to the cooperation is to the perforation, more can be to the abundant suction of sputum on the respiratory track inner wall, the atress is less, reduces the probability of bleeding, and it is more abundant to inhale the phlegm, and the phlegm mouth of inhaling that the slope set up simultaneously makes the nurse intubate easier. The sputum suction device has the advantages of reasonable design, simple structure and convenience in use, can prevent the respiratory tract inner wall from being damaged, and has better sputum suction effect.

Drawings

Fig. 1 is a schematic structural view of the ultra-smooth sputum suction tube of the present invention.

Detailed Description

The embodiments of the present invention will be further described with reference to the accompanying drawings so as to facilitate the further understanding of the present invention by those skilled in the art, and do not constitute a limitation to the right thereof.

Referring to fig. 1, the ultra-smooth sputum aspirator comprises a catheter 1, wherein a sputum aspirator 2 is arranged at the front end of the catheter 1, at least one pair of through holes 3 are arranged on the catheter close to the sputum aspirator 2, an opening is arranged at the rear end of the catheter 1, a catheter connector 6 is arranged at the opening, a hydrophilic coating 5 is coated on the catheter 1, the coating length of the hydrophilic coating 5 extends from the sputum aspirator 2 backwards by 15cm-40cm, the thickness of the hydrophilic coating 5 is 1-2mm, a scale mark 4 is arranged on the outer surface of the catheter 1, so that the insertion depth can be conveniently measured by clinical personnel, the catheter 1 is a non-DEHP PVC pipe, namely a PVC pipe without DEHP (or plasticizer), and the material has no toxicity to infants and young men and no reproductive organism, has good biocompatibility, has no obvious stimulation to respiratory tract mucosa, and reduces stimulation to respiratory tract mucosa and various complications; the hardness of the material is about Share (65 +/-5) A, the material is moderate and soft, mucous membranes are prevented from being scratched when the material advances in the respiratory tract of a patient, a sputum suction port 2 at the front end of a catheter 1 is obliquely arranged, the inclination angle is 45-70 degrees, two pairs of through holes 3 are arranged, the axes of the two pairs of through holes 3 are perpendicular and staggered, one pair of through holes is symmetrically arranged at two sides of a scale mark 4 along the axis of the catheter 1, namely 4 holes are formed in the two pairs of through holes, one pair of through holes is arranged at two sides of the scale mark 4, the other pair of through holes is perpendicular to the scale mark and staggered, and the aperture of the through holes 3 is 1.1 +/-0.3 mm, so that sputum on the inner wall of the respiratory tract can be more fully sucked out; through the scale marks 4, the insertion depth can be conveniently observed by clinical staff during intubation, and the operation of the clinical staff is convenient; after the hydrophilic coating 5 swells on the surface of water, a layer of ultra-smooth film is formed, the insertion resistance of the catheter can be effectively reduced, the respiratory tract mucous membrane is prevented from being damaged, and the catheter connector adopts a horn mouth design, so that the catheter can be conveniently connected with various negative pressure suction machines on the market.
