Embodiment 1

[0029] Such as figure 1 As shown, the applicator of this embodiment includes an applicator head 2 , a piston rod 32 , a piston head 31 , a sealing cap 5 , a first one-way valve 24 , a second one-way valve 25 and a third one-way valve 13 .

[0030] Such as Figure 2-4 As shown, the first one-way valve 24 , the second one-way valve 25 and the third one-way valve 13 are similar in structure, and all include a valve body 241 and a valve core 242 . The valve body 241 is made of hard material (such as PVC), and the valve core 242 is a sealing gasket made of elastic material (such as rubber). The valve body 241 is provided with a valve core groove 2411 matching the profile of the valve core 242 , and the bottom surface of the groove is provided with a connecting portion 2412 and a flow hole 2413 . Wherein the connection part 2412 is arranged at the center position of the groove bottom of the spool groove 2411, and is composed of a connecting post 24121 and a hemispherical stopper 2...

Embodiment 2

[0037] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the end of the piston head 31 connected to the piston rod 32 of this embodiment forms the first limit surface 33, and the piston rod hole 53 is smaller than the cross section of the piston head 31, so that the piston head 31 cannot be drawn out from the piston rod hole 53, forming a second limiting surface 26 corresponding to the first limiting surface 33, and limiting the stroke of the piston head 31 by the second limiting surface 26 to the first limiting surface 33.

[0038] If will quantitatively apply medicine, also can utilize piston head 31 strokes to carry out quantitative extruding, convenient medical personnel grasps the medicine quantity.

[0039] Of course, in this embodiment, the sealing cover 5 needs to be removed before the piston head 31 and the piston rod 32 can be pulled out.

Embodiment 3

[0041] Such as Figure 6 As shown, on the basis of the above-mentioned embodiments, this embodiment is further provided with a drug applicator cartridge 1, and one end of the drug applicator cartridge is detachably connected to the sealing cap 5 through threads. The other end of the drug applicator 1 is provided with a reinforcing plate 11 , the reinforcing plate 11 is provided with a guide hole 15 at a position corresponding to the piston cavity 21 , and a ventilation hole 111 is provided around the guide hole. The reinforcing plate 11 can keep the drug applicator 1 in a stable cylindrical structure, and can guide the piston rod 32 through the guide hole 15 provided thereon, so that the moving process is smooth. The vent hole 111 is used for the third one-way valve 13 to suck enough air from the applicator cartridge. Of course, corresponding to the diameter of the guide hole 15 in the first embodiment, it should be enough to allow the piston head 31 to be pulled out.

Abstract

The invention relates to a medicine applicator for local treatment of oral mucosa. The medicine applicator comprises a medicine applying head, a piston rod, a piston head, a sealing cover, a first one-way valve, a second one-way valve and a third one-way valve; the medicine applying head is provided with a piston cavity, a medicine storage cavity and a medicine outlet hole; the first one-way valvecommunicates with the medicine storage cavity and the piston cavity and is opened unidirectionally towards the piston cavity, the second one-way valve communicates with the piston cavity and the medicine outlet hole and is opened unidirectionally towards the medicine outlet hole, and the medicine outlet hole is arranged in one side of the medicine applying head; one end of the sealing cover is detachably connected with the medicine applying head and is in sealed connection with the medicine storage cavity, and the third one-way valve is arranged on the sealing cover and is opened unidirectionally towards the medicine storage cavity; and the piston head is arranged in the piston cavity, the position, corresponding to the piston cavity, of the sealing cover is provided with a piston rod hole, and the piston rod passes through the piston rod hole to be connected to the piston head. According to the medicine applicator, a medical worker or a patient can conveniently apply a medicine to oral mucosal lesions, and the medicine applicator is suitable for accurate positioning and administration of the surfaces with complex shapes of various parts of an oral cavity, avoids contact of the medicine by hands, is quick, simple and hygienic, and improves the medicine application efficiency and medication experience.

Description

Technical field: [0001] The invention relates to a drug applicator in the treatment process, in particular to a drug applicator in the oral cavity local treatment process. Background technique: [0002] Oral ulcers, erosions, papules, and plaques are a series of common lesions that occur in the oral mucosa. The treatment process usually requires the application of medicine to the oral lesions. At present, there is a lack of corresponding medicine application tools. Applying medicine with bare hands will lead to contamination of ointment or gel medicine and saliva on fingers, which is unhygienic, waste of medicine, and unsatisfactory treatment experience. If a cotton swab is used to apply the medicine, the medicine will be more wasted due to the adhesion of the cotton wool to the medicine, and the amount of the medicine actually distributed on the lesion surface is extremely limited, and the medicine is unevenly distributed and easy to fall off, making it difficult to obtain ...
