Probe-tube type drug delivery device convenient for nurses to hold by hands for respiratory medicine

Abstract

The invention relates to the technical field of respiratory medicine drug delivery devices, and discloses a probe-tube type drug delivery device convenient for nurses to hold by hands for respiratorymedicine. The drug delivery device includes a shell, a liquid storage bag is fixedly connected to the interior of the shell, the surface of the liquid storage bag is fixedly connected with a hollow channel, the interior of the hollow channel is movably connected with a hollow rod, and two sides of the hollow rod are movably connected with air pressure bags; the surface of the hollow rod is movablyconnected with a flexible tube, one end, far away from the hollow rod, of the flexible tube is fixedly connected with a sliding plate, the bottom of the sliding plate is movably connected with an airspring, the lower end of the air spring is movably connected with a spring rod, the surface of the spring rod is movably connected with a guide rod, and two sides of the guide rod are hinged with supporting plates. Squeezing force of an air pressure bag is removed artificially, powder is brought out and flows out from a rubber tube, and the air pressure bag sucks gas under the action of the own elastic recovery force, and gradually returns to a normal state, so that the effect of positioning a spray coating position by using the shape of the air pressure bag can be achieved.

Description

technical field [0001] The invention relates to the technical field of respiratory drug delivery devices, in particular to a probe-type drug delivery device for respiratory departments that is convenient for nurses to hold. Background technique [0002] Respiratory patients mainly include respiratory diseases and lung diseases. The common respiratory disease site is the throat area. The existing technology uses liquid medicine brewing powder or intravenous injection for treatment. With the continuous development of medical technology, the above two treatments Due to the poor therapeutic effect, the method is gradually replaced by the method of drug spraying. [0003] Due to the twists and turns of the throat, the existing drug spraying mechanism cannot perfectly locate the part to be treated, and the amount of drug sprayed is often judged by the experience of medical staff, resulting in poor treatment effect on the patient; in addition, in the future When the spraying devic...

Problems solved by technology

[0002] Respiratory patients mainly include respiratory diseases and lung diseases. The common respiratory diseases are the throat area. The existing technology uses liquid medicine brewing powder or intravenous injection for treatment. With the continuous development of medical technology, the above two treatments As the treatment effect is poor, it is gradually replaced by drug spraying.

[0003] Due to the twists and turns of the throat, the existing drug spraying mechanism cannot perfectly locate the part to be treated, and the amount of drug sprayed is often judged by the experience of medical staff, resulting in poor treatment effect on the patient; in addition, in the future When the spraying equipment is placed inside the patient's mouth, due to the conditioned reflex of the human body's saliva secretion mechanism, the patient's mouth will secrete more saliva, which will affect the spraying path of the drug. Therefore, a hand-held respiratory probe that is convenient for nurses Tube drug delivery device came into being
