Abstract
The utility model relates to a novel clinical medical instrument, in particular to a visualized tract drug delivery device which comprises a local drug delivery atomizer, a visible device and a transparent pipe made of medical polymer materials. A local drug delivery channel and an observation tract are axially arranged in the pipe. The local drug delivery atomizer is connected with a connector arranged at the back end of the pipe, drugs are delivered to the local drug delivery channel through the connector, and optical fibers are arranged in the observation tract and are led to the outer side of the pipe from the observation tract to form a leading-out end connected with a signal input end of the visible device. The visualized tract drug delivery device is efficient in use and can accurately deliver drugs to tract nidus portions.
Description
Technical field
It is efficient that this utility model relates to a kind of clinical medical apparatus and instruments of using, particularly a kind of use, accurately visual doser in local tract.
Background technology
The treatment of pulmonary infection is to give antimicrobial drug by oral or vein.Medicine arrives lesions position by blood circulation, reaches therapeutic purposes.Although intravenously administrable can make pulmonary parenchyma reach effective antibacterials concentration level, be penetrated into tube chamber limited with the endocrine medicine of pipe.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.Although 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., thereby has limited it by the heavy dose of application of vein.It is but very little on the impact of the drug level in blood that local atomization sucks antibacterials, so not only can reduce the dosage of systemic administration, and avoid the toxic and side effects of medicine, therefore encourages the auxiliary treatment of Inhalation in Treating 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 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 due to the 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 that the atomising device that does not still have the present listing of proof provides can effectively arrive the small airway of lung, can not determine whether atomization makes enough sustained drugs be deposited on the pulmonary infection kitchen range, and the atomization suction is subject to patient respiration fitness and patient dependence impact, can not guarantee that enough active drugs arrive the pathological changes part, this just makes being widely used of antibacterials of atomization suction be restricted.Therefore, at present in the urgent need to a kind of, can guarantee to suck antibacterials and can more effectively make enough antibacterials arrive the small airway of lung and the nebulization equipment of pulmonary infection focus, simultaneously, this device also can offer intestinal, the tracts such as urogenital tract carry out topical, better clinical service work.
Summary of the invention
In order to overcome above shortcomings on prior art, it is a kind of efficient that this utility model provides, accurately visual doser in local tract.
this utility model 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, in body, axially be provided with topical passage and observation chamber, 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, termination at the topical passage is provided with cribriporal.
This utility model apparatus is because the advantage that has adopted said structure to have is: owing to having visuality, avoided the blindness in the atomization suction process, can make the atomization inhalation pipe front end arrive the lung small airway and exactly the inflammation of pulmonary be located, increase inflammation local antibacterial medicine administration concentration and hold time, also can reach intestinal, administration is carried out in the urogenital tract part, realize that high efficiency hangs down the toxic and side effects antibacterial therapy, and this is simple to operate without specification requirement.Add the turning traction steel wire, be convenient to the body that enters the positions such as lung small airway, intestinal, urogenital tract is controlled, also be convenient to the duct wall that this doser can more clearly be observed lung small airway, intestinal, urogenital tract.
