Description

A kind of tracheostoma defecator

Technical field

This utility model relates to medical apparatus and instruments, relates in particular to a kind of tracheostoma defecator for the cut patient of throat.

Background technology

Normal person breathes and relies on nasal cavity air amount to enter trachea through pharyngeal cavity, cavum laryngis, and nasal cavity front end has vibrissa can stop that larger dust and foreign body enter, and normal person relies on throat's vocal cord vibration, then coordinates pharyngeal cavity, oral cavity, nasal cavity resonance to send various sound.

Laryngeal carcinoma is a kind of head-neck malignant tumor that occurs in throat, and clinical manifestation is hoarseness, dyspnea, larger to harm, and its sickness rate accounts for 1%～2% of whole body malignant tumor.Because diseased region is in throat, when early stage, patient can think it is commonly encountered diseases such as pharyngolaryngitis and not drawing attention by mistake, and result has delayed treatment.The method for the treatment of laryngeal carcinoma is mainly operation Combined with Radiotherapy and chemotherapy at present, and when operation, some patient often needs to carry out total laryngectomy operation.Postoperative patient, because throat is cut, has not had vocal cords normally not sound, and loses nasal respiration function.Because postoperative patient has lost nasal respiration function, so need to offer tracheostoma at patient's cervical region, allow patient breathe by the trachea of cervical region.In order to make can again to pronounce to speak without larynx patient, otorhinolaryngology expert both domestic and external and head and neck surgical specialist have been attempted several different methods, what have also matches with tracheostoma possibly, the most common with esophageal voice, trachealgia sound and artificial sound in these methods, patient can select above-mentioned three kinds of diverse ways according to the s own situation of oneself.Although help postoperative patient again to pronounce to speak very important, be pronunciation or breathe and all will rely on tracheostoma, so the protection of tracheostoma can not be ignored.In the ordinary course of things, in order to prevent that the excessive or foreign body of tracheal secretion from easily entering trachea, existing tracheostoma protective measure is to hide at postoperative patient's cervical region long periods of wear trachea pipe box or with gauze, but these two kinds of methods are not very desirable, brings a lot of inconvenience to patient's life; And because tracheostoma is sensitive part, is easy to cause and infects or pathological changes, so need a kind of safer reliable device to make up the deficiency in prior art.

The specific embodiment

The structure that Figure of description illustrates, ratio, size etc., equal contents in order to coordinate description to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of this utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that this utility model can produce and the object that can reach, all should still drop in the scope that technology contents that this utility model discloses can contain.Simultaneously, in this description, quote as " on ", the term such as D score, 'fornt', 'back', " centre ", also only for ease of understanding of narrating, but not in order to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of this utility model.

As Fig. 1-Figure 3 shows that a kind of tracheostoma defecator of this utility model, described tracheostoma defecator filtered air during for the patient respiratory of cut throat, described tracheostoma defecator comprises tubular base 1 and end cap 2, described tubular base 1 comprises abutting end 11 and link 12, described abutting end 11 is connected with the tracheostoma of patient's cervical region, and described link 12 is connected with end cap 2.Described end cap 2 can be to be socketed on tubular base 1, also can be arranged on tubular base 1 by buckle, can also be threaded connection and match with tubular base 1 etc.In described tubular base 1, be provided with nano ventilated net 3, described tubular base 1 and end cap 2 are silica gel material, also comprise ventilative pad pasting 4, and described ventilative pad pasting 4 is socketed in the outer wall Shang Yu patient throat adhesion of tubular base 1.Described ventilative pad pasting 4 can be difformity as required, such as circle, ellipse, strip etc.

In this utility model in order to facilitate installation and the location of nano ventilated net 3, abutting end 11 diameters of described tubular base 1 are less than link 12 diameters, between abutting end 11 and link 12, form gear platform, when saying that nano ventilated net 3 is placed into tubular base 1, can directly nano ventilated net 3 be leaned on gear platform like this.Above-mentioned is preferred version in this utility model, for example, gear platform is directly set in tubular base 1 and also can meets and install and location needs.

As shown in Figure 1, end cap 2 described in the utility model is tubulose, comprise and compress end 21 and positive stop end 22, the outer wall of described positive stop end 22 is provided with annular retaining ring 221, described compression end 21 extend into and in tubular base 1, compresses nano ventilated net 3, by compression, hold 21 further nano ventilated net 3 to be carried out spacingly, and in the present embodiment, on the compression end 21 of described end cap 2, be also connected with spacing back-up ring 24; The annular retaining ring 221 of described positive stop end 22 contacts with the link 12 of tubular base 1, because the external diameter of annular retaining ring 221 is greater than the external diameter of tubular base 1 link 12, so annular retaining ring 221 has played spacing effect on the one hand, be to be convenient to end cap 2 and tubular base 1 removes and installs on the other hand.As mentioned above, between end cap 2 and tubular base 1, can there is multiple connected mode, in the present embodiment preferably, the inwall of described tubular base 1 link 12 is provided with spacing preiection 121, the outer wall of described end cap 2 is provided with limited impression 23, and described spacing preiection 121 and described limited impression 23 match.Further, described spacing preiection 121 and limited impression 23 are provided with two pairs, and its position can be adjacent setting, can be to be also oppositely arranged etc.For the ease of the cooperation of spacing preiection 121 and limited impression 23, the height of described spacing preiection is between 1～2mm, and the degree of depth of described limited impression is between 1.5～2.5mm.

When using this utility model, need only the abutting end of tubular base 1 11 is connected with the tracheostoma of patient's cervical region, then pass through ventilative pad pasting 4 by this utility model and patient's cervical region adhesion, nano ventilated net 3 is put into tubular base 1, finally end cap 2 is installed and coordinated with tubular base 1.Also very simple when needs are changed nano ventilated net 3, end cap 2 is pulled down to replacing.

In sum, a kind of tracheostoma defecator of this utility model, easy to use, reliable, the filtration problem while efficiently solving patient respiratory.So, thereby this utility model has effectively overcome practical problems more of the prior art, have very high value and use meaning.

Above-mentioned embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting this utility model.This utility model also has many aspects under the prerequisite without prejudice to overall thought, to improve, and for person skilled in the art scholar, all can, under spirit of the present utility model and category, can above-described embodiment be modified or be changed.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that this utility model discloses and technological thought, must be contained by claim of the present utility model.
