Abstract
The invention provides a nebulizer capable of preventing inverse flow of nebulization liquid. A round seat piece is fastened horizontally to the middle portion of the inner side wall of a bottom pipe opening of a three-way connecting pipe; the middle portion of the round seat piece is provided with a round air hole; a longitudinal lift rod is arranged in the middle portion of a transverse channel in the three-way connecting pipe; the longitudinal lift rod is arranged right above the round seat piece; the bottom rod end of the longitudinal lift rod is firmly connected with the top of an extension spring; the bottom of the extension spring penetrates through the round air hole downward and is then fastened onto the middle portion of the top surface of a round baffle piece; the round baffle piece is suspended below the round seat piece via the extension spring; the diameter of the round baffle piece is greater than the diameter of the round air hole; one end of a lift rope is fastened to the center portion of the bottom surface of the round baffle piece and the other end of the lift rope is firmly connected with a drop ball; the drop ball is suspended below the round baffle piece via the lift rope; the drop ball can be placed in a chimney pipe. The nebulizer is novel in structure, great in practicability and user-friendly in design.
Description
Technical field
The invention belongs to medical aid material field, relate to a kind of nebulizer having and preventing atomized liquid from refluxing.
Background technology
The situation that the sickbed patients needed due to the state of an illness in hospital can surprisingly be toppled over due to stupor or atomized liquid bottle that is sleeping and that run in nebulizer or overturn during being carried out being atomized process of reducing phlegm, in this case the medicinal liquid in atomized liquid bottle can be refluxed out and be flowed directly to by pipeline in the mouth of patient, the danger by mistake inhaled the most not only can occur, also can increase sense of discomfort to patient, also can increase the nursing difficulty of nursing staff simultaneously.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of nebulizer having and preventing atomized liquid from refluxing, when atomized liquid bottle is surprisingly toppled over, the present invention can effectively act as stoping atomized liquid to flow to the effect in patient's mouth, and it has novel structure, practicality is higher, design more humane feature.
In order to achieve the above object, the present invention takes following concrete technical measures: a kind of have the nebulizer preventing atomized liquid from refluxing, it by liquid storage bottle, lid, oxygen catheter, three-limb tube, sting pipe, choked flow mechanism forms, it is characterised in that
The inner bottom of liquid storage bottle makees conical shaped depression, liquid storage bottle is used for storing medicinal liquid, the open top of liquid storage bottle is connected with lid, the end face of lid is provided with convection current air chamber protruding upward, the sidewall of this convection current air chamber is provided with valve, one pipe end of oxygen catheter is socketed with this valve, another pipe end of oxygen catheter is then communicated to Central oxygen-supply joint, the end face vertically-arranged of convection current air chamber has a chimney pipe, the bottom mouth of pipe of three-limb tube can be socketed on the top of chimney pipe, three-limb tube be internally provided with choked flow mechanism, the front mouth of pipe of three-limb tube can be socketed with the rear pipe end stinging pipe, the rear mouth of pipe of three-limb tube is provided with a circular film；
nullWherein，Choked flow mechanism includes longitudinal suspension rod、Coil tension spring、Circular seat sheet、Rounded tabs、Lifting rope、Pendant ball，In the middle part of the medial wall of the bottom mouth of pipe of three-limb tube, level is fastened with circular seat sheet，The middle part of circular seat sheet offers circular pore，The middle part of three-limb tube inner transverse passage is provided with a longitudinal suspension rod，Longitudinal suspension rod is arranged at the surface of circular seat sheet，The bottom bar end of this longitudinal direction suspension rod is fastenedly connected with the top of coil tension spring，The bottom of coil tension spring is downward through being anchored on after circular pore in the middle part of the end face of rounded tabs，Rounded tabs is suspended in the lower section of circular seat sheet by coil tension spring，The diameter of rounded tabs is more than the aperture of circular pore，One end of lifting rope is anchored on the bottom center position of rounded tabs，The other end of lifting rope is then fastenedly connected with pendant ball，Pendant ball is suspended in the lower section of rounded tabs by lifting rope，Pendant ball can be inserted in chimney pipe.
When the liquid storage bottle in the present invention is in normal vertically-arranged state, the pendant ball being positioned in chimney pipe pulls downwards rounded tabs due to self gravitation by lifting rope, now it is opened a segment distance between rounded tabs and circular seat sheet, coil tension spring now is in the state of being stretched, and the medicinal liquid after atomization can enter three-limb tube from the circular pore of circular seat sheet smoothly；When the liquid storage bottle in the present invention is surprisingly toppled over, pendant ball contacts with the medial wall of chimney pipe, due to lifting rope lose pendant ball gravity pull, so rounded tabs now is realized being close to circular seat sheet bottom surface and circular pore carrying out the purpose of block by the reset of the coil tension spring effect of pulling back simultaneously, thus effectively act as stoping the medicinal liquid in liquid storage bottle to flow to the effect in patient's mouth by circular pore.
The beneficial effects of the present invention is, it has novel structure, practicality is higher, design more humane feature.
With embodiment, the present invention is illustrated further below in conjunction with the accompanying drawings.
