Problems solved by technology

[0003] However, this method of applying medicine often has the following disadvantages in actual use: if the injection pressure of the injection cylinder is insufficient, the medicine mist will fall rapidly when it is sprayed, and the contact area with the top of the nasal cavity is limited, and most of it adheres to the bottom area of ​​the nasal cavity , leading to uneven spraying of the liquid medicine, thereby reducing the efficacy of the treatment; and if the spray pressure is too high, the impact force of the scattered medicine mist will be greater, which will easily cause damage to the fragile mucous membrane in the nasal cavity, thereby aggravating the disease.

Embodiment 1

[0026] refer to Figure 1-3 , a nasal medicine device for upper respiratory tract infection in pediatrics, comprising a syringe 1, a suction tube 6 communicating with the inside of the syringe 1 is installed on the side wall of the syringe 1, and a cap is installed on the suction tube 6. The piston 2 is sealed and slidably connected inside the injection cylinder 1, and the side wall of the piston 2 is fixedly connected with the push rod 3. The side wall of the injection cylinder 1 is provided with a rotary groove 101, and the rotary cylinder 5 is connected with the rotary cylinder 5 in the rotary groove 101. Specifically, The two end faces and the circumferential side walls of the drum 5 are in close contact with the inner wall of the rotary tank 101 . The circumferential inner wall of the rotary groove 101 is provided with a plurality of drug outlet holes 102, the side wall of the drum 5 is provided with an annular groove 501, and the inner wall of the annular groove 501 is p...

Embodiment 2

[0033] refer to Figure 4 , the difference from the first embodiment is that the annular groove 501 is sealed and slidably connected with the annular plate 12, the side wall of the annular plate 12 is fixedly connected with the first bellows 13, and the end of the first bellows 13 away from the annular plate 12 is fixedly connected On the inner wall of the annular groove 501, a strip groove 8 is opened on the inner wall of the injection barrel 1, and an air supply device for supplying air to the first bellows 13 is installed in the strip groove 8, and the first bellows 13 is installed with a The outlet pipe 14 that communicates.

[0034] The air supply device includes a second corrugated pipe 9 fixedly connected to the inner wall of the bar-shaped groove 8, and an air inlet pipe 11 communicating with the inside thereof is installed on the second bellows pipe 9, and the air inlet pipe 11 communicates with the air outlet pipe 14 through a rotary joint, and the bar The inner wal...

Abstract

The present invention discloses an upper respiratory infection nasal cavity medication device for department of pediatrics. The upper respiratory infection nasal cavity medication device comprises a syringe, a piston is slidably connected in the syringe in a sealed mode, a push rod is fixedly connected to the side wall of the piston, a rotary groove is formed in the side wall of the syringe, and a rotary cylinder is rotatably connected in the rotary groove in a sealed mode; a plurality of medicine outlet holes are formed in the circumferential inner wall of the rotary groove, an annular groove is formed in the side wall of the rotary cylinder, a plurality of spraying holes are formed in the inner wall of the annular groove, a driving device for driving the rotary cylinder to rotate is installed on the piston, and the injection cylinder is communicated with the rotary groove through a plurality of through holes. A medicine inlet hole is formed in the end, close to the through hole, of the rotary cylinder. The driving device is used for driving the rotary cylinder to rotate continuously, so that liquid medicine can be discharged along one side of the rotating rotary cylinder, small injection pressure can be input, the liquid medicine can be evenly sprayed to the periphery of the interior of the nasal cavity, damage to mucosa of the nasal cavity is prevented, and meanwhile the treatment medicine effect can be effectively improved.

Description

technical field [0001] The invention relates to the relevant technical field of a pediatric medication application device, in particular to a pediatric upper respiratory tract infection nasal cavity medication device. Background technique [0002] When treating pediatric upper respiratory tract infection and nasal cavity-related diseases, the medicinal liquid is often drawn into the syringe, and then an atomizing nozzle is installed on the syringe, so that the mist medicinal liquid is sprayed into the nasal cavity of the patient. [0003] However, this method of applying medicine often has the following disadvantages in actual use: if the injection pressure of the injection cylinder is insufficient, the medicine mist will fall rapidly when it is sprayed, and the contact area with the top of the nasal cavity is limited, and most of it adheres to the bottom area of ​​the nasal cavity , resulting in uneven spraying of the medicinal solution, thereby reducing the therapeutic eff...
