Devices and methods for treating a diseased tracheobronchial region in a mammal. The device can be a stent which can include a sustained-release material such as a polymer matrix with a treatment agent. The stent can be bioabsorbable and a treatment agent can be incorporated therewith. A treatment method can be delivery of a stent to a tracheobronchial region by a delivery device such as a catheter assembly.

The invention relates to an oral tablet and a preparation method thereof. The oral tablet is mainly prepared from the following raw materials in parts by weight: 2-4 parts of coptis root leaf, 1-3 parts of honeysuckle, 1-3 parts of licorice, 1-3 parts of radix platycodi and 0.5-2 parts of peppermint. The oral tablet has good mouth feel and unique taste (a person feels sweet when the oral tablet enters the mouth, the person can feel both sweet taste and bitter taste after the oral tablet enters the mouth, weaker bitter taste still exists in the oral cavity even after the oral tablet is completely dissolved, and the person also feels coarse, fresh and cool when the oral tablet enters the mouth) and the oral tablet can be eaten as candy. Because of addition of the traditional Chinese medicines of the coptis root leaf and the like, the oral tablet has an obvious effect for ulceratiue stomatitis and throat gall which are caused by suffering from excessive internal heat and is combined withthe honeysuckle with the function of clearing away heat and toxic materials, the peppermint with the functions of dispelling wind heat and relieving sore-throat, the radix platycodi with the functions of promoting the dispersing function of the lung, relieving sore-throat and benefiting the voice and the licorice with the function of protecting the throat and the tracheal bronchus; the five medicines all serve as the raw materials, which can truly achieve the therapeutic effects of clearing and benefiting the throat.

The invention discloses a video tracheobronchial foreign body microscopic examination general anesthesia system. In the system, a microscopic examination anesthesia ventilation laryngotracheal microscope is a three-way special-shaped tube (1-5); the front end of the three-way special-shaped tube (1-5) serves as a video end outlet (1-6); an installation sliding telescopic tube (1-3) and a pipeline of a tracheobronchial microscope are arranged in the three-way special-shaped tube (1-5); and the outer side of one circle of the pipeline (1-1) is provided with a breathing air duct (2-10). According to the invention, an anesthesia breathing ventilation structure used for video anesthesia and extraction of microscopic examination foreign bodies, microscopic examination software programming and automatic storage and output of microscopic examination results are realized; a similar equipment system does not exist at home and abroad, and improved ventilation for an infant intratracheal foreign body microscope and general anesthesia are reported but are not perfect and reliable; and a microscopic examination anesthesia system for increasing the infant intratracheal foreign body curing rate and the survival rate, reducing damage caused by accidental suction of infants and improving the survival quality is needed.

The invention relates to the field of immunological detection, in particular to a pepsase chemiluminescent immunoassay kit and a method thereof. The pepsase chemiluminescent immunoassay kit provided by the invention comprises: 1) a pepsase antigen calibrator; 2) sample collecting solution at a pH value of 2 to 3; 3) sample diluents at a pH value of 6 to 8; 4) a microporous plate coated by a pepsase antibody; 5) a pepsase antibody marker; 6) a chemical luminescence substrate liquid; and 7) concentrated cleaning solution. The kit provided by the invention can detect the pepsase content in gastric juice, esophageal content, throat secretion and tracheal bronchus secretion, judge if gastroesophageal reflux happens according to the result of the pepsase detection and judge the treatment effect of stomach diseases and change of state of illness according to the detected pepsase content. The kit has the advantages of noninvasiveness, simplicity, convenience, quickness, sensitivity, stability and the like.

Disclosed is a device for stimulating the tracheobronchial air of a patient suffering from an obstructive ventilatory disorder and able to modify the rheology of his tracheobronchial mucus, which includes a negative pressure generator, a physiological interface able to interface the device with the patient's respiratory apparatus, a connection pipe connecting the physiological interface to the negative pressure generator, and a control circuit capable of controlling the negative pressure generator, during the passive expiration phase, for the application of a succession of alternation of negative pressure and venting impulses with a determined frequency and a duty cycle determined during a first part of an expiration cycle and then a second frequency and a second duty cycle during a second part of the expiration cycle and to reiterate a defined number of expiration cycles.

The invention relates to a dry powder inhaler capable of preventing respiratory transmission of Mycobacterium tuberculosis, which can effectively solve the drug problem of preventing and treating tuberculosis infection by Mycobacterium tuberculosis through the respiratory tract. %, rifampicin sustained-release microspheres 19.9-90%, glidant 0.1-5%, first mix isoniazid sustained-release microspheres, rifampicin sustained-release microspheres, and glidants together, Packed in gelatin, plastic capsules or aluminum-plastic blisters, or packaged in a multi-dose dry powder inhalation device in the form of a reservoir; the composition of the present invention is scientific, reasonable, easy to manufacture, good in use effect, and beneficial to powder The body enters the alveoli, and the drug is delivered to the alveoli to be absorbed. It is effectively used to kill and inhibit the Mycobacterium tuberculosis in the trachea, bronchi and alveolar secretions in the respiratory tract, and reduce the number of droplets with floating ability that tuberculosis patients exclude into the surrounding environment. To block the spread of Mycobacterium tuberculosis in the public environment is of great significance to the prevention of tuberculosis.
