Description

Tracheal cannula cleaner

Technical field

What the present invention relates to is a kind of cleaner that is used for technical field of medical instruments, specifically, is a kind of tracheal cannula cleaner.

Background technology

Up to now, per nasal or oral trachea cannula or to carry out Failure Treated with Mechanical Ventilation through tracheostomy tube be the common method that clinical medicine rescues critical patients such as cardiopulmonary depletion almost are the unique methods of coming back to life.But because respiratory secretions is assembled at tracheal intubation tube wall secretions, high speed airflow is taken away moisture, forms the expectorant crust gradually, blocks the tracheal intubation tube chamber, causes that airway resistance increases, even patient's death by suffocation, and this is one of common complication of tracheal intubation.Per nasal or oral trachea cannula or assemble through tracheostomy tube tube chamber generation secretions form the expectorant crust, stop up the tube chamber of tracheal intubation.Almost have no idea at present to remove, unique method is to change intubate.But, no matter be tracheotomy, or per nasal or oral trachea cannula, changing intubate all is a very dangerous job.For the patient of tracheotomy, in back 5 days of incision, because sinus tract does not form, complication such as hemorrhage take place easily especially.For per nasal or oral trachea cannula patient,, require to pull out intubate in the short time at the utmost point, like clockwork intubate is inserted glottis, this also is the work that a difficulty is great, be fraught with risks.If the doctor can not finish this work in the extreme time, the patient can cause brain injury because of the anoxia overlong time, and weight person causes death, and this situation occurs in often to be changed in the tracheal intubation process.Therefore, rise that day since tracheal intubation is born, the problem of the block of secretion intubate of going in group is perplexing the clinician always.From textbook the earliest,, repeatedly these life-threatening serious problems are being discussed to the document of most recent.

Find by prior art documents, Zhang Shuyuan (" Jiangsu clinical medicine " was rolled up the 347th page of 5 phase in 1997 the 1st) in " the 32 routine clinical analysiss of tracheal intubation complication " literary composition mentions, insert among the patient at 208 routine tracheas, have 21 examples that the expectorant plugging takes place, the incidence rate that the tracheal intubation sputum stops up is 10%.Even more serious problem is, do not see that so far the instrument that any cleaning tracheal intubation is arranged comes out, and the method that the prevention intubate is blocked remains humidifying and inhales expectorant, but does not reduce the risk that intubate is blocked.

In further literature search, find as yet and the identical or similar report of theme of the present invention " tracheal cannula cleaner ".

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of tracheal cannula cleaner is provided, make it guarantee that the tracheal intubation cleaning is with unobstructed, stopping tracheal intubation expectorant crust blocks, prevent the generation that suffocates, avoid changing tracheal intubation, thereby reduce risk and the medical expense of bringing because of scavenge trunk more.

The present invention is achieved by the following technical solutions, the present invention includes pipe and nook closing member, and pipe and nook closing member are separate, supporting use.

The front end of described pipe is the knife edge sample mouth of pipe, and when the front end of pipe was inserted into the tracheal intubation intracavity gradually, the mouth of pipe that pipe is sharp can be removed secretions and the expectorant crust on the intubate lumen wall.

Described pipe is " C " type, and its external diameter is the 6-8 millimeter, and the size of external diameter is different different because of the model of supporting tracheal intubation, 38 centimetres of the length of pipe.When the front end of pipe is inserted into the tracheal intubation intracavity gradually, because the tensile effect of " C " shape pipe shaft, can keep the mouth of pipe of pipe to contact, can effectively remove secretions and expectorant crust on the intubate lumen wall with the front end that guarantees pipe with the close of tracheal intubation lumen wall.

Be provided with a through hole on 3 centimetres the tube chamber in distance pipe rear end.This through hole is used for controlling the negative pressure of gas.When through hole is hidden fully, keep maximum negative pressure in the pipe pipeline; When through hole is partly hidden, can reduce the negative pressure in the pipe pipeline; When through hole is open fully, then stop the negative pressure in the pipe pipeline.

The rear end of described pipe is connected with vacuum extractor, removes the supply of the negative pressure power of secretions on the intubate lumen wall and expectorant crust to guarantee pipe.

Described nook closing member is a cylindrical structural, and the front end of nook closing member is vertical tangent plane, and the rear end of nook closing member is a handle, and the diameter of nook closing member equates that with the internal diameter of pipe the length of nook closing member equals the length of pipe.Nook closing member can directly be inserted in the pipe, when pipe work, if there is the expectorant crust to block the tube chamber of pipe, and then available nook closing member mediation pipe.

During work, the rear end of pipe is connected with the suction catheter of vacuum extractor, the front end of pipe is inserted in the tracheal intubation, along with deepening continuously of pipe, the mouth of pipe of knife edge sample strikes off the secretions and the expectorant crust of intubate lumen wall, because the effect of the intraluminal negative pressure of pipe, secretions and expectorant crust constantly are inhaled in the cleaner tube chamber, and drain into the drainage bottle of vacuum extractor from the mouth of pipe of pipe rear end.To the demand of negative pressure, open or stop up through hole during according to work, thus the intraluminal negative pressure of control pipe.In case the tube chamber of expectorant crust cramming is arranged, pipe can be extracted tracheal intubation, then the rear end of nook closing member from pipe is inserted in the tube chamber of pipe, the intraluminal secretion clearing of pipe clean after, pipe works on again.

The invention has the beneficial effects as follows: 1, the present invention is direct, simple, will directly strike off with the vacuum suction removing to combine, and all is easy to realize from the material to technology; 2, " C " shape pipe shaft can contact the sharp mouth of pipe with the good of tracheal intubation inwall, thereby the assurance pipe can thoroughly be removed the secretions on the tracheal intubation lumen wall; 3, avoid carrying out the work of replace tubes, thereby reduced medical risk and medical expense because of the tracheal intubation block of secretion; 4, reduce the number of times of inhaling expectorant, thereby reduced the risk that air flue infects, also alleviated nurse's workload simultaneously.In a word, clinical practice of the present invention, this perplexs the problem of clinician's last 100 years to have solved the block of secretion intubate up hill and dale, can bring remarkable economic efficiency and social benefit.
