Abstract

The utility model discloses a multi-functional nose and pharynx breath vessel which is made into the structure of a circular arc shape or a nose and pharynx physiological curvature shape. The inner of the multi-functional nose and pharynx breath vessel is provided with an oxygen supply conduit, a main blowhole and a side blowhole. A scale is arranged on the outside of the multi-functional nose and pharynx breath vessel and a nozzle is provided with surrounding edge. Hence, the utility model can be used for breath and meanwhile for oxygen inhalation and high frequency jetting oxygen supply. The utility model has the advantages of simple operation, convenient operation, easy fabrication, low cost and good breath performance. The multi-functional nose and pharynx breath vessel, which is safe and disposable, can also be made into serial products of different specifications, and hence the multi-functional nose and pharynx breath vessel is an ideal medical breath vessel device.

Description

Multi-functional nose and pharynx breath vessel

This utility model relates to a kind of nasopharynx airway device of medical equipment, is specially adapted to urgent patient's ventilation breath and oxygen supply.

The airway that existing market is sold and hospital is commonly used is the oropharynx airway, this oropharynx airway shortcoming: if cause ventilatory effect bad insert Oxygen tube in pipeline after.Because price is more expensive, many people use, and easily cause cross infection.This oropharynx airway causes patient to inhale the expectorant inconvenience after inserting oropharynx, in oropharynx, can not deposit for a long time in addition, complication such as easily cause that mucosa festers.Because the activity of tongue can cause moving of oropharynx airway riding position, uses inconvenient.This in addition oropharynx airway can only be made ventilation breath, can not cure by oxygen therapy simultaneously or the high frequency jet oxygen supply, only has simple function.

The purpose of this utility model is to avoid to provide outside the above-mentioned deficiency of the prior art a kind of nasopharynx airway that inserts nasal cavity, this utility model can ventilation breath, directly oxygen supply and high frequency jet oxygen supply again, therefore have multi-functional, and this utility model also to have a ventilatory effect good, safe and reliable, characteristics such as riding position is difficult for moving, and is easy to use, this utility model processing is simple, with low cost, be convenient to do disposable use.

The purpose of this utility model is achieved in that

The structure fabrication of nasopharynx airway becomes garden camber or nasopharynx physiological bending type, the garden arc internal diameter 2 of garden camber structure is of a size of 25 to 45 millimeters, external diameter 3 and is of a size of 30 to 55 millimeters, the arc length size 1 of garden camber structure or nasopharynx physiological bending type structure arc length size 1 are 100 to 200 millimeters, and nasopharynx physiological bending type structure lumen diameter 10 is of a size of 3 to 12 millimeters.And at nasopharynx airway inner chamber tube wall making is set and gives oxygen channel 7, give oxygen channel 7 mouth of pipe outer ends compacting connecting interface pipe 8.Main passage 5 of processing and side passage 6 are set in nasopharynx airway lower end, scribe length scales 4 on the tube wall of the airway outside, the mouth of pipe of airway is made surrounding edge 9 structures, and this utility model processes with the non-toxic plastic injection moulding.

This utility model compared with prior art has following advantage:

1, this utility model is provided with at airway inner chamber tube wall and make gives oxygen channel 7, so it can make ventilation breath, can directly cure by oxygen therapy simultaneously again, can also make the high frequency jet oxygen supply, therefore has multi-functionally, and venting capability is good.

2, this utility model inserts nasal cavity and finishes ventilation breath, does not therefore influence to patient and inhales expectorant nebulae inhalation etc., is difficult for making riding position to move, and is simple to operate reliable for effect.

3, this utility model is provided with main, side passage in the airway lower end, and preventing can also have the side passage to work on behind the foreign body obstruction master passage, and is therefore safe and reliable.

4, this utility model can be made into the nasopharynx airway of different size specifications, adapts to all ages and classes people's use, and is marked with rule at airway outside tube wall, crosses deeply or shallow excessively when preventing to use, and it is extremely convenient therefore to use.

5, this utility model is easy to make, is convenient to produce in batches, and is with low cost, satisfies and does disposable use, prevents cross infection, is a kind of ideal medical utility conduit device.

Below in conjunction with accompanying drawing this utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

With reference to Fig. 1, structure fabrication of the present utility model becomes garden camber or nasopharynx physiological bending type, the garden arc internal diameter 2 of garden camber structure is of a size of 25 to 45 millimeters, external diameter 3 is of a size of 30 to 55 millimeters, the arc length 1 of garden camber structure is of a size of 100 to 200 millimeters, the garden arc internal diameter 2 that one of embodiment nasopharynx airway is made is of a size of 40 millimeters, external diameter 3 is of a size of 50 millimeters, arc length 1 is of a size of 160 millimeters, it can be made into the series of products of different size specifications simultaneously, so that adapt to different size age people's use, for example the size of baby's use is more a little bit smaller.Structure of the present utility model also can be made into nasopharynx physiological bending type, its arc length 1 is of a size of 100 to 200 millimeters, lumen diameter 10 is of a size of 3 to 12 millimeters, one of embodiment nasopharynx physiological bending type structure arc length 1 is of a size of 160 millimeters, lumen diameter 10 is of a size of 10 millimeters, equally also can be made into the series of products of the specification that varies in size, nasopharynx airway pipe thickness size was generally 0.5 millimeter when embodiment made, process with the non-toxic plastic injection moulding, be convenient to produce in batches, and cost is low, handling ease, and embodiment adopts transparent non-toxic plastics injection molded.

Be provided with to make at nasopharynx airway inner chamber tube wall simultaneously and give oxygen channel 7, give oxygen channel 7 mouth of pipe outer ends compacting connecting interface pipe 8, it is simultaneously injection molded that embodiment adds man-hour with the nasopharynx airway for oxygen channel 7, being 0.5 to 1 millimeter when generally making to the diameter of oxygen channel 7 gets final product, give oxygen channel 7 mouth of pipe outer end connecting interface pipes 8, embodiment adopts commercially available common infusion fluid joint for plastic tube, it is compressed on oxygen channel 7 mouth of pipe seams simultaneously during injection moulding, is used for oxygen therapy and high frequency oxygen spray interface.

Main passage 5 of processing and side passage 6 are set in the lower end of nasopharynx airway, and on the pipe outer wall, scribe length scales 4, embodiment master's passage 5 and side passage 6 its processing diameter according to the different corresponding changes of specification, are generally processed diameter and are got final product in 2 to 6 millimeters.When main passage 5 had foreign body obstruction, side passage 6 can also continue the respiration channel effect, and is therefore safe and reliable.It is centimetre scale that length scales 4 embodiment that scribe on the pipe outer wall mark scale; prevented dark or shallow excessively when inserting nasal cavity; inserting the nasal cavity degree of depth can be shown by scale; the mouth of pipe of nasopharynx airway is made surrounding edge 9 structures in addition; example surrounding edge 9 structures are protruded the garden surrounding edge of about 2 millimeters thick of external diameter of pipe when fabrication and processing; its effect insertion nasal cavity rear defence on-slip is gone in the oropharynx, plays safeguard protection.Insert nasal cavity when this utility model uses, riding position is difficult for moving, and does not influence patients accepting oxygen inhalation, atomizing, the treatment of suction expectorant again, and is simple to operate, reliable for effect, easy to use, penetration and promotion easily.
