Description
Technical field
The present invention relates to medical instruments fields, more particularly, to a kind of novel intratracheal fistula mouth holder.
Background technology
Since various oesophaguses or tracheal disease are formed by esophago-tracheal fistula mouth, so that oesophagus endocrine is flowed into air flue, make
At Severe Pulmonary Infection, severe patient's threat to life.Patient is unable to oral feeding, seriously reduces patient's because fistula mouth exists
Quality of life.For the treatment of esophago-tracheal fistula, the therapy of relative efficiency is that Stent Implantation blocks fistula in the prior art
Mouthful, it can reduce or even prevent oesophagus endocrine flowing into air flue in this way, reduce the generation of aspiration pneumonia.Part plugging effect
Good patient, it might even be possible to oral feeding, quality of making the life better.But during clinical practice, discovery is asked there are following
Topic：1）Branch frame peripheral（Especially at fistula mouth）More secretion is often gathered, bacterial reproduction is be easy to cause and causes to infect.
2）Due to the presence of fistula mouth holder, can not or be not easy to being administered treatment at fistula mouth.3）It is easy to happen displacement, is unfavorable for fistula
The closure of mouth, severe patient fall off the life that can threaten patient.
Invention content
The purpose of the present invention is to provide a kind of novel intratracheal fistula mouth holder, the novel intratracheal fistula mouth holder can be convenient for
Suction accumulates in the secretion at fistula mouth, or even treatment can be administered to fistula mouth.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of novel intratracheal fistula mouth holder is provided, including rack body, fistula mouth connection machine at human body interior tracheae fistula mouth can be placed in
