Abstract
The invention relates to novel medical equipment for clinic, and provides a visualization cavity dosing device which comprises a local dosing atomizer, a visualization device and a transparent tube made of medical high polymer material, wherein a local dosing channel and an observing cavity are formed in the tube in the axial direction, the local dosing atomizer is connected with a connecting part arranged at the rear end of the tube, and drugs are conveyed to the local dosing channel through the connecting part. An optical fiber arranged inside the observing cavity is led out of the tube through the observing cavity to form the leading-out end, and the leading-out end is connected with a signal input end of the visualization device. The visualization cavity dosing device is efficient to use, and can accurately conduct dosing on focus parts of cavities.
Description
Technical field
It is efficient to the present invention relates to a kind of clinical medical apparatus and instruments of using, particularly a kind of use, accurately visual doser in the local tract.
Background technology
The treatment of pulmonary infection is to give antimicrobial drug by oral or vein.Medicine to lesions position, reaches therapeutic purposes by blood circulation.Although intravenously administrable can make pulmonary parenchyma reach effective antibacterials concentration level, be penetrated into tube chamber and the pipe endocrine medicine limited.Especially multi-drug resistant bacteria is insensitive to common antibiotics, and the routine dose intravenous administration is difficult to reach the active drug concentration for the treatment of in focus of infection, and causes therapeutic effect poor.Though and sensitive antibiotic such as aminoglycoside, polymyxin class, mould rope etc. can play certain antibacterial action through the ages, its treatment window is narrower, easily causes nephrotoxicity and neurotoxicity etc., uses by vein is heavy dose of thereby limited it.Local atomizing suction antibacterials are but very little to the influence of the drug level in the blood, so not only can reduce the dosage of systemic administration, and avoid the toxic and side effects of medicine, therefore encourage to suck the auxiliary treatment for the treatment of as whole body therapeutic.Air flue provides a direct route of administration, high-efficiency atomizer makes antibacterials can pass through the direct targeted of air flue in lung, this medication can make that antimicrobial drug concentration is higher than the several times of intravenously administrable in expectorant and the lung tissue, and is higher than the minimum inhibitory concentration of pneumonia due to the treatment common bacteria far away.
It is the key of successfully treating pneumonia that enough drug level and enough medicines are held time, but the pharmaceutical aerosol that still there is not evidence to confirm that the atomising device of listing at present provides can effectively arrive the little air flue of lung, can not determine to atomize and whether make enough medicines continue to be deposited on the pulmonary infection kitchen range, and the atomizing suction is subject to patient respiration fitness and patient dependence influence, can not guarantee that enough active drugs arrive the pathological changes part, this just makes atomizing suck the widely-used of antibacterials and is restricted.Therefore, press at present and a kind ofly can guarantee to suck antibacterials and can more effectively make the capacity antibacterials arrive the little air flue of lung and the atomizing suction apparatus of pulmonary infection focus, simultaneously, this device also can offer intestinal, tracts such as urogenital tract carry out topical, the better service clinical position.
Summary of the invention
In order to overcome above shortcomings on the prior art, the invention provides a kind of efficient, visual doser in the local tract accurately.
The present invention adopts following technical scheme to realize above-mentioned purpose: a kind of visual cavity/canal drug administration device comprises the topical nebulizer, visual device and the transparent tube body that adopts medical macromolecular materials to make, axially be provided with topical passage and observation chamber in the body, described topical nebulizer connects the connector that is arranged on the body rear end, by connector medicine is delivered to the topical passage, in described observation chamber, be provided with optical fiber, optical fiber leads to body by observation chamber and forms exit outward, exit connects the signal input part of visual device, the observation chamber termination of described body front end is transparent sealing, is provided with cribriporal in the termination of topical passage.
Apparatus of the present invention is owing to the advantage that has adopted said structure to have is: owing to have visuality, avoided the blindness in the atomizing suction process, the little air flue of atomizing intake line front end arrival lung is reached exactly locatees the inflammation of pulmonary, increase inflammation local antibacterial medicine administration concentration and hold time, also can reach intestinal, administration is carried out in the urogenital tract part, realizes the low toxic and side effects antibacterial therapy of high efficiency, and this no specification requirement simple to operate.Add the turning traction steel wire, be convenient to the body that enters positions such as the little air flue of lung, intestinal, urogenital tract is controlled, also be convenient to the duct wall that this doser can more clearly be observed the little air flue of lung, intestinal, urogenital tract.
