Problems solved by technology

[0003] At present, most people hold the medicine bottle containing ofloxacin in their hands, and then move the medicine bottle so that the spray nozzle is inserted into the ear, and then press and squeeze the medicine bottle continuously, because human hands are prone to tremors phenomenon, it is easy to cause the bottle to shake and puncture the eardrum, and because the person needs to press the bottle continuously, it is difficult to control the amount of medicine injected, resulting in inconsistent doses of medicine injected each time, and another person helps Spraying is more troublesome

Embodiment 1

[0021] refer to Figure 1-Figure 4 , an ofloxacin drug delivery device for otitis externa, comprising a rubber arc-shaped block 1, a fixing plate 2, an annular rubber stopper 3, a mounting seat 4 and a drug delivery mechanism 5, and the front and rear ends of the right side of the rubber arc-shaped block 1 All are fixedly connected with a fixed plate 2, the lower part of the right side of the fixed plate 2 is embedded with an annular rubber plug 3, and the lower part of the left side of the outer surface of the fixed plate 2 is fixedly connected with a mounting seat 4, and the mounting seat 4 is provided with a drug delivery mechanism 5, The drug delivery mechanism 5 cooperates with the annular rubber stopper 3 .

[0022] Medication mechanism 5 comprises hollow pipe 51, one-way liquid inlet pipe 52, dial 53, rubber skin 54, swing plate 55, collar 56, liquid outlet pipe 57, first spring 58, annular piston block 59, clip block 511, the second spring 512 and the elastic member 5...

Embodiment 2

[0026] refer to figure 1 and figure 2 , the main difference between this embodiment and embodiment 1 is that in this embodiment, a quantitative mechanism 6 is also included, and the quantitative mechanism 6 includes an arc plate 61, a guide sleeve 62, a u-shaped rod 63, a third spring 64, a screw rod 65, nut 66, L-shaped push block 67 and the fourth spring 68, the middle of the rear part of the front dial 53 and the middle of the front part of the rear dial 53 are all slidingly provided with a screw rod 65, and the left end of the screw rod 65 is fixedly connected with an L-shaped spring. Push block 67, the right end of L-shaped push block 67 is in contact with swing plate 55, the left part of screw rod 65 is provided with nut 66, and the fourth spring 68 is wound between the right part of screw rod 65 and the right side of shift plate 53, and the front side is hollow Pipe 51 outer right side anterior portion and rear side hollow tube 51 outer rear side rear parts are all fi...

Embodiment 3

[0029] refer to figure 1 Compared with Embodiment 1 and Embodiment 2, the main difference of this embodiment is that in this embodiment, a sponge block 7 and a fifth spring 8 are also included, and the inner surface of the rubber arc block 1 is evenly spaced and connected with five fifth springs. Spring 8, sponge piece 7 is affixed between five fifth spring 8 tail ends.

[0030] Also include fixed seat 9 and hanging rod 10, both sides fixed plate 2 inner side bottom left sides are all fixedly connected with fixed seat 9, the fixed seat 9 middle part rotation type is connected with the hanging rod 10 that cooperates with ear.

[0031] When the device was worn on the head, the sponge block 7 was in contact with the operator's head, and because of the effect of the fifth spring 8, the sponge block 7 was in contact with the people's head all the time. In this way, the device can be adapted to be worn more firmly on heads of different sizes.

[0032] When the annular rubber plug ...

Abstract

The invention relates to a drug delivery device, and in particular relates to an ofloxacin drug delivery device for external auditory meatus inflammation. The technical problem is how to design an ofloxacin drug delivery device for external auditory meatus inflammation, which is more convenient for people to spray ofloxacin into an ear, prevents ear membrane from being punctured and ensures that the amount of the sprayed ofloxacin is consistent. The ofloxacin drug delivery device for external auditory meatus inflammation comprises an arc-shaped rubber block, fixing plates are fixedly connectedto two ends of the arc-shaped rubber block, and an annular rubber plug is fixedly connected to one portion of each fixing plate in a penetrating mode. According to the invention, through a one-way liquid inlet pipe and a swing plate are arranged, ofloxacin can be pumped into a hollow tube, then a poking plate is pulled to enable the hollow tube to make contact with the annular rubber plug, then the swing plate is pressed continuously, the liquid outlet tube can move into an ear, and the liquid outlet tube sprays the ofloxacin into the ear to apply medicines, so that the situation that the eardrum is stabbed due to the fact that a medicine bottle is used to apply the medicines is avoided, and the ofloxacin drug delivery device is more convenient to use.

Description

technical field [0001] The invention relates to a drug delivery device, in particular to an ofloxacin drug delivery device for otitis externa. Background technique [0002] Otitis externa usually refers to diffuse otitis externa, while localized otitis externa is called furuncle externa. Otitis externa is chronic non-specific inflammation of the skin and subcutaneous tissue of the external auditory canal caused by bacterial, fungal infection or allergy. Mostly in summer and autumn, can be divided into acute otitis externa and chronic otitis externa. The acute ones are mainly infiltrating inflammation, and the chronic ones are mainly desquamation. People with fungal infection are also called fungal otitis externa. When people have symptoms of otitis externa, they need to spray ofloxacin into the ear to treat otitis externa. [0003] At present, most people hold the medicine bottle containing ofloxacin in their hands, and then move the medicine bottle so that the spray nozz...
