Abstract
The utility model provides a liquid medicine nebulizer. The liquid medicine nebulizer comprises an external gas catheter, an aerosol generation portion, a breathing mask, a liquid medicine chamber, an aerosol outlet on the liquid medicine chamber, an external gas introduction opening and a handle. The liquid medicine nebulizer is characterized in that the external gas catheter is connected with one end of the external gas catheter through threads or a pneumatic connector. The connecting end of the external gas catheter and an air source is provided with threads or an air source pneumatic connector. The liquid medicine nebulizer guarantees that an external air source and the nebulizer are reliable and airtight in connection, can also avoid disconnection even if the external gas pressure is relatively large, can gain precious rescue time when the liquid medicine nebulizer is used for rescuing a critically ill patient, and is convenient to operate and easy to achieve.
Description
Technical field
This utility model belongs to manufacture technology field of medical appliance, is a kind of medicinal liquid atomizing device specifically.
Background technology
Medicinal liquid atomizing device is mainly used in treating respiratory tract disease, its principle is: medicinal liquid is injected to nebulizer, pass into again pure air or medical oxygen, nebulizer makes medicinal liquid and air or medical oxygen be thoroughly mixed to form aerosol, and the breathing mask of patient by nebulizer sucks the object that medicine after atomization reaches treatment.
Conventional medicinal liquid atomizing device mainly by: aerosol generating unit, aerosol outlet, breathing mask, medicinal liquid cavity, extraneous gas introducing port, extraneous gas conduit, handle form.Aerosol generating unit is positioned at medicinal liquid cavity, and extraneous gas introducing port and aerosol outlet are arranged on medicinal liquid cavity.The extraneous gas introducing port of current medicinal liquid atomizing device is a hollow pipe with tapering normally, and the two ends of extraneous gas conduit are cylindrical hollow pipe, the connected mode of extraneous gas conduit and extraneous gas introducing port is that cylindrical hollow pipe is inserted on taper outer gas introduction port, and the other end of extraneous gas conduit is also like this with being connected of source of the gas.Because nebulizer and extraneous gas conduit are used plastic production conventionally, in actual use because of material aging, repeatedly plug the reasons such as elasticity degeneration and often occur throwing off phenomenon, especially, when the external gas pressure is larger, throws off phenomenon and take place frequently.This just brings very big inconvenience to patient, when medicinal liquid atomizing device is used for rescuing critical patient, may delay valuable rescue time.
Summary of the invention
The problems referred to above that this utility model exists for prior art, provide a kind of medicinal liquid atomizing device, guarantee that external air source is connected with nebulizer reliable, air tight, and easy to operate, easily realization.
The purpose of this utility model is achieved through the following technical solutions:
A kind of medicinal liquid atomizing device, comprise: aerosol outlet, extraneous gas introducing port and handle on extraneous gas conduit, aerosol generating unit, breathing mask, medicinal liquid cavity, medicinal liquid cavity, it is characterized in that, described extraneous gas introducing port is connected with screw thread or pneumatic joint with one end of extraneous gas conduit.
Improvement to technique scheme: the link of described extraneous gas conduit and source of the gas arranges screw thread or configuration source of the gas pneumatic joint.
Further improvement to technique scheme: described extraneous gas introducing port is the external screw thread mouth of pipe, the two ends of described extraneous gas conduit are the female thread mouth of pipe.
A kind of improvement to technique scheme: described pneumatic joint is pneumatic ready-packaged joint, pneumatic ready-packaged joint is arranged on described extraneous gas introducing port, and described extraneous gas conduit is a flexible pipe that bore is consistent with the pipe aperture of pneumatic ready-packaged joint.
The another kind of technique scheme is improved: described pneumatic joint is pneuma-lock joint, and pneuma-lock joint is arranged on described extraneous gas introducing port, and described extraneous gas conduit is a flexible pipe that bore is consistent with the pipe aperture of pneuma-lock joint.
This utility model compared with prior art has the following advantages and good effect:
This utility model extraneous gas introducing port and source of the gas adopt and are threaded with the two ends of extraneous gas conduit respectively, connect reliable.Or extraneous gas introducing port and source of the gas are connected with pneumatic ready-packaged joint or lock-on connection with extraneous gas conduit two ends respectively, connect reliably, and easy to operate.Extraneous gas conduit is a flexible pipe, can also often prune the two ends of flexible pipe, makes to connect more reliable.When even the external gas pressure is larger, also can avoid throwing off phenomenon and occur, when being used for rescuing critical patient, can win valuable rescue time.
Accompanying drawing explanation
Fig. 1 is the assembling exploded view of this utility model medicinal liquid atomizing device.
In figure: 1-aerosol generating unit, the outlet of 2-aerosol, 3-breathing mask, 4-medicinal liquid cavity, 5-extraneous gas introducing port, 6-extraneous gas conduit, 7-handle.
The specific embodiment
Referring to Fig. 1, the embodiment of a kind of medicinal liquid atomizing device of this utility model, comprising: aerosol outlet 2, extraneous gas introducing port 5 and handle 7 on extraneous gas conduit 6, aerosol generating unit 1, breathing mask 3, medicinal liquid cavity 4, medicinal liquid cavity 4.Described extraneous gas conduit 6 is screw thread with the link of source of the gas, described extraneous gas introducing port 5 is connected with extraneous gas conduit 6 use screw threads or pneumatic joint, when being threaded, extraneous gas introducing port 5 is the external screw thread mouth of pipe (or female thread mouth of pipe), and the two ends of extraneous gas conduit 6 are the female thread mouth of pipe (or external screw thread mouth of pipe).
Above-mentioned pneumatic joint is pneumatic ready-packaged joint or pneuma-lock joint, pneumatic ready-packaged joint or pneuma-lock joint are arranged on extraneous gas introducing port 5, and extraneous gas conduit 6 is bore flexible pipes consistent with the pipe aperture of pneumatic ready-packaged joint or pneuma-lock joint.
Fig. 1 has provided the medicinal liquid atomizing device that a kind of extraneous gas introducing port 5 and source of the gas are threaded with extraneous gas conduit 6 use, and in figure, extraneous gas introducing port 5 is external screw thread, and extraneous gas conduit 6 is female thread.The great advantage being threaded is to connect reliably, but can make extraneous gas conduit 6 have certain distortion when operation.
When adopting pneumatic ready-packaged joint to connect, as long as the turn of pinning on ready-packaged joint inserts rear trip spring circle by extraneous gas conduit 6 one end, easy to operate, air tight in order to guarantee, hose end need to be sheared smooth.
When adopting pneuma-lock joint to connect, first screw off the pressure cap on lock-on connection, extraneous gas conduit 6 one end are inserted on lock-on connection and screw pressure cap again through pressure cap, this mode reliability is high, and can not cause the distortion of extraneous gas conduit.After using a period of time extraneous gas conduit 6 termination elasticity termination can be cut off to one section when bad, continue to use, do not affect result of use at all.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and this utility model is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of having done, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
