Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
As shown in fig. 1 to 5, the present invention includes a needle cylinder 1 with two closed ends, a first piston 2 and a second piston 3 which are arranged at a left-right interval are installed in the needle cylinder 1, the first piston 2 is arranged on the left, a pressure spring 4 is installed between the first piston 2 and the left end of the needle cylinder 1, and a cross bar 5 extending out of the needle cylinder 1 is installed on the right end of the second piston 3; a transverse pipe 6 is fixedly installed at the left end of the needle cylinder 1, a liquid inlet hole 7 and a liquid outlet hole 8 are formed in the side wall of the needle cylinder 1, when the pressure spring 4 is in a natural state, the liquid outlet hole 8 is sealed by the first piston 2, the liquid inlet hole 7 is located on the right side of the first piston 2, the liquid inlet hole 7 is communicated with the transverse pipe 6 through a liquid inlet pipe 9, the liquid outlet hole 8 is communicated with the transverse pipe 6 through a liquid outlet pipe 10, and a one-way valve 11 capable of feeding liquid into the needle cylinder 1 is installed on the liquid inlet pipe 9; a circular baffle 12 is coaxially arranged on the transverse pipe 6, an annular air bag 13 is embedded on the outer edge of the baffle 12, an air pipe 14 is communicated between the air bag 13 and the left end of the syringe 1, a through hole 15 in the left-right direction is formed in the baffle 12, and a liquid return pipe 16 is communicated between the through hole 15 and the right end of the syringe 1.
The baffle 12 is provided with air release holes 17 in the left and right directions, and the aperture of the air release holes 17 is smaller than that of the through holes 15.
The outer wall of the right end of the needle cylinder 1 is provided with a convex edge 18, and the right end of the cross rod 5 is provided with a vertical plate 19 vertical to the cross rod.
The right end of the needle cylinder 1 is sealed by an end cover 20 screwed by screw threads, and the inside of the needle cylinder 1 can be cleaned comprehensively by unscrewing the end cover 20 and extracting the second piston 3.
In the initial state of the invention, the first piston 2 is contacted with the second piston 3, and under the action of the pressure spring 4, a space is arranged between the first piston 2 and the left end of the needle cylinder 1, and at the moment, the first piston 2 seals the liquid outlet hole 8.
When the device is used, the left end of the transverse pipe 6 is inserted into liquid medicine, then the vertical plate 19 is pulled rightwards so as to pull the second piston 3 to move rightwards, negative pressure generated between the first piston 2 and the second piston 3 enables the liquid medicine to be sucked into the needle cylinder 1 between the first piston 2 and the second piston 3 through the transverse pipe 6, the liquid inlet pipe 9 and the liquid inlet hole 7 in sequence, and air on the right side of the second piston 3 is discharged through the liquid return pipe 16 and the through hole 15; inhale behind enough capacity's liquid medicine, stretch into the duct with the left end of violently managing 6 in, make baffle 12 be located the duct mouth position, and make through-hole 15 under, it is last to lose heart hole 17, then forefinger and middle finger buckle protruding edge 18, the thumb is pressed riser 19 and is promoted left, horizontal pole 5 promotes second piston 3 left, thereby because first piston 2 seals drain hole 8 this moment, consequently, the liquid medicine between first piston 2 and the second piston 3 can not be discharged, first piston 2 can be along with second piston 3 left motion this moment, thereby first piston 2 can push into gasbag 13 through trachea 14 with its left air and make gasbag 13 inflation, gasbag 13 inflation and duct inner wall hug closely, simultaneously, after first piston 2 moved a section distance left, thereby first piston 2 can move to the left side of drain hole 8 and make drain hole 8 open, continue to promote left this moment riser 19 can impress the liquid medicine between two pistons in violently managing 6 through 8 and drain pipe 10 and then spout the duct mouth of the left end of violently managing 6 and advance the duct into the duct from the duct mouth position of auditory canal The air in the ear canal can be discharged from the air release hole 17 by flushing.
When the second piston 3 moves leftwards, negative pressure is generated on the right side of the second piston 3, liquid medicine in the auditory canal flows outwards to the baffle 12, and due to the action of the negative pressure on the right side of the second piston 3, the liquid medicine is sucked into the needle cylinder 1 on the right side of the second piston 3 through the through hole 15 and the liquid return pipe 16, so that the liquid medicine is prevented from overflowing.
After washing the completion, take out violently pipe 6 from the auditory canal, then pulling riser 19 right, horizontal pole 5 pulling second piston 3 moves right, and first piston 2 moves right under the effect of pressure spring 4, and second piston 3 moves right and can discharge the waste liquid on its right side through liquid pipe and through- hole 15, and 3 left sides of second piston produce the negative pressure and can inwards breathe in through violently pipe 6 and feed liquor pipe 9.
When the device is cleaned, the left end of the transverse pipe 6 and the baffle 12 are immersed in the cleaning liquid, and the vertical plate 19 is pushed and pulled back and forth; when thorough and complete cleaning is needed, the end cover 20 at the right end of the needle cylinder 1 is unscrewed for cleaning.
The invention seals the auditory canal by the air bag 13 during washing, and waste liquid can be collected in the needle cylinder 1 by the liquid pipe while the auditory canal is cleaned, thereby preventing the waste liquid from overflowing to pollute clothes and equipment and providing cleaner and more sanitary treatment environment for patients and medical staff.
