Abstract
The utility model discloses an external auditory canal drainer which comprises a head part and a ball part. The rear end of the head part is connected with the front end of the ball part in an obturation way; the head part comprises a vent-pipe and a head-part one-way air valve, and the head-part one-way air valve comprises a steel ball and a rubber hose, air is only allowed to enter the head part from the ball part; the ball part comprises a rubber ball and a ball-part one-way air valve; the front end of the rubber ball is provided with a connecting hole which is connected with the head part; the ball-part one-way air valve is positioned at the rear end of the bal part and is composed of a steel ball and a rubber hose, and air is only allowed to enter the ball part from the outside. The length of the head part of the external auditory canal drainer is 15-20 mm, the outside diameter of the vent-pipe is 40-50 mm, and the inside diameter is 15-20 mm. The joint of the head part and the ball part is provided with an annular protector which can prevent the head part from inserting too deep into the external auditory canal; a groove is arranged around the vent-pipe of the head part, thereby being convenient for water to be drained. The external auditory canal drainer can quickly drain water accumulation in the external auditory canal caused by swimming, bathing, and the like, thereby avoiding tympanitis, and the like.
Description
Technical field
This utility model relates to a kind of small appliance that the hydrops that people's ear external auditory meatus causes because of reasons such as swimming, have a bath can be discharged fast.
Background technology
Swimming is sports that are fit to very much broad masses of the people, both can take exercises, and be again the good method of avoiding heat a kind of summer.But in when swimming, the water inlet of people's external auditory meatus often takes place, bad discharge causes external ear and middle ear to infect easily, generation otitis media etc., and above-mentioned situation also happens occasionally having a bath.The way of present solution has only with some little cotton swabs, inserts external auditory meatus and absorbs water, and still absorbing water with cotton swab is difficult for blotting only, and needs insertion darker, uses the improper tympanum that causes easily of cotton swab to damage to people unsafe sensation, particularly child.For this reason, we have invented a kind of meatus acusticus externus draining equipment, as long as it is put into external auditory meatus, push balloon gently, and the water in the external auditory meatus is discharged rapidly, make people can not cause otitis media etc. because of external auditory meatus hydrops in swimming or after having a bath.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming of existing product, and the hydrops that causes because of swimming, have a bath etc. with in the external auditory meatus that can be quick, simple to operate, easy to use is discharged, and avoids taking place otitis media etc.Its low price, simple to operate, easy to use.In order to achieve the above object, this utility model has adopted following technical scheme.
Meatus acusticus externus draining equipment comprises head and bulb, and the rear end of head is connected with the front end in bulb is airtight, and described head comprises exhaustor and head Non-return air valve, and the head Non-return air valve comprises steel ball and sebific duct, is only permitted gas and enters head from the bulb; Described bulb comprises rubber bulb and bulb Non-return air valve; the front end of rubber bulb has the connecting hole that is connected with head, and the bulb Non-return air valve is positioned at the rear end in bulb, comprises steel ball and sebific duct; only permitted gas and entered the bulb from the external world; the head length of meatus acusticus externus draining equipment is 15～20mm, and the external diameter of exhaustor is 40-50mm, and internal diameter is 15-20mm; there is a ring protection device at the position that head is connected with the bulb; it is dark excessively to prevent that head from inserting external auditory meatus, fluted around the exhaustor of head, is convenient to water and discharges.Only need during use it is put into external auditory meatus, push balloon gently, the water in the external auditory meatus is discharged rapidly, makes people can not cause otitis media etc. because of external auditory meatus hydrops in swimming or after having a bath.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan structure figure of this utility model head.
Fig. 3 is the side-looking structure chart of this utility model head.
Fig. 4 is the profile of this utility model head.
1. heads, 2. bulbs, 3. exhaustors, 4. head Non-return air valves, 5. steel balls, 6. sebific ducts, 7. rubber bulbs, 8. bulb Non-return air valves, 9. connecting holes, 10. ring protection devices, 11. grooves among the figure
As seen from the figure, this utility model patent comprises head 1 and bulb 2, and the rear end of head 1 is connected with the front end in bulb 2 is airtight, and described head 1 comprises exhaustor 3 and head Non-return air valve 4, head Non-return air valve 4 comprises steel ball 5 and sebific duct 6, is only permitted gas and 2 enters head 1 from the bulb; Described bulb 2 comprises rubber bulb 7 and bulb Non-return air valve 8; the front end of rubber bulb 7 has the connecting hole 9 that is connected with head 1; bulb Non-return air valve 8 is positioned at the rear end in bulb 2; comprise steel ball and sebific duct; only permitted gas and entered bulb 2 from the external world; head 1 length of meatus acusticus externus draining equipment is 15～20mm; the external diameter of exhaustor 3 is 45mm; internal diameter is 18mm; there is a ring protection device 10 at the position that head 1 is connected with bulb 2; it is dark excessively to prevent that head from inserting external auditory meatus, fluted 11 around the exhaustor 3 of head, is convenient to water and discharges.
In use, meatus acusticus externus draining equipment head 1 is inserted in the external auditory meatus, push bulb 2 repeatedly with hands, at this moment, because the effect of bulb check valve 8 and head check valve 4, gas only can unidirectionally enter external auditory meatus by bulb 2 and head 1 fast from exhaustor 3, and has the gas of certain pressure the hydrops that retains in the external auditory meatus can be extruded external auditory meatus, and hydrops is discharged external auditory meatus by external auditory meatus wall and groove 11.
