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
The present invention relates to a kind of clinical medical apparatus and instruments, particularly a kind of use is efficient, accurately visual doser in the tract of local.
Background technology
The treatment of pulmonary infection gives 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, penetrate into tube chamber limited with the endocrine medicine of pipe.Especially multi-drug resistant bacteria is insensitive to common antibiotics, and routine dose intravenous administration is difficult to the active drug concentration reaching treatment in focus of infection, and causes therapeutic effect poor.And although sensitive antibiotic such as aminoglycoside, polymyxin class, through the ages mould rope etc. can play certain antibacterial action, its treatment window is narrower, easily causes nephrotoxicity and neurotoxicity etc., thus limits it by the application of vein heavy dose.Local Neulized inhalation antibacterials are but very little on the drug level impact in blood, so not only can reduce the dosage of systemic administration, and avoid the toxic and side effects of medicine, therefore encourage Inhalation in Treating as the auxiliary treatment of whole body therapeutic.Air flue provides a direct route of administration, high-efficiency atomizer makes antibacterials can by the direct targeted of air flue in lung, this medication can to make in expectorant and lung tissue antimicrobial drug concentration higher than the several times of intravenously administrable, and far away higher than the minimum inhibitory concentration of pneumonia caused by treatment common bacteria.
It is the key of successful treatment pneumonia that enough drug level and enough medicines are held time, but the pharmaceutical aerosol there still be not evidence to confirm that the atomising device of listing at present provides effectively can arrive the small airway of lung, can not determine to be atomized and whether make enough sustained drugs be deposited on pulmonary infection stove, and Neulized inhalation is subject to patient respiration fitness and patient dependence impact, can not ensure that enough active drugs arrive pathological changes local, this just makes widely using of Neulized inhalation antibacterials be restricted.Therefore, can guarantee that sucking antibacterials can more effectively make enough antibacterials arrive the small airway of lung and the nebulization equipment of pulmonary infection focus in the urgent need to a kind of at present, simultaneously, this device also can be supplied to intestinal, the tracts such as urogenital tract carry out topical, better clinical service work.
Summary of the invention
In order to overcome above shortcomings in prior art, the invention provides a kind of efficient, accurately visual doser in the tract of local.
The present invention adopts following technical scheme to realize above-mentioned purpose: a kind of visual cavity/canal drug administration device comprises topical nebulizer, visual device and the transparent tube body adopting medical macromolecular materials to make, axially topical passage and observation chamber is provided with in body, described topical nebulizer connects the connector being arranged on body rear end, by connector, medicine is delivered to topical passage, optical fiber is provided with in described observation chamber, 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 confinement, the termination of topical passage is provided with cribriporal.
The advantage that apparatus of the present invention has owing to have employed said structure is: owing to having visuality, avoid the blindness in Neulized inhalation process, atomization inhalation pipe front end can be made to arrive lung small airway and locate the inflammation of pulmonary exactly, increase inflammation local antibacterial medicine administration concentration and hold time, also intestinal can be reached, administration is carried out in urogenital tract local, realize the low toxic and side effects antibacterial therapy of high efficiency, and this is simple to operate without technical requirement.Add turning traction steel wire, the body be convenient to entering the positions such as lung small airway, intestinal, urogenital tract controls, and is also convenient to the duct wall that this doser more clearly can observe lung small airway, intestinal, urogenital tract.
