Description

Technical Field

[0001] The utility model relates to the technical field of temperature transmitter fixing, in particular to a medicine sprayer used for the nasal cavity. Background Art

[0002] The sprayer is a commonly used treatment tool in respiratory medicine. For example, when treating rhinitis, the sprayer can deliver the medicine directly to the lesion for treatment, thereby improving the treatment effect.

[0003] In application number CN202122341174.2, the utility model relates to a nasal sprayer, including a medicine bottle, a bottle cap, a spray tube, a medicine outlet tube, a limiting sleeve, a first spring and a pressurizing device. The top of the medicine bottle is provided with a bottle cap, the top of the bottle cap is provided with a spray tube, the spray tube is provided with a medicine outlet tube, the lower end of the medicine outlet tube extends into the bottom of the medicine bottle, the upper sleeve of the spray tube is provided with a limiting sleeve, the upper sleeve of the spray tube between the bottle cap and the limiting sleeve is provided with a first spring, the upper end and the lower end of the first spring are respectively connected to the limiting sleeve and the bottle cap, and the outer wall of the upper end of the medicine bottle is provided with a pressurizing device. The beneficial effect of the utility model is that when the spray tube is inserted into the nasal cavity, the limiting sleeve can move on the spray tube, and the first spring contracts at the same time, which can prevent the spray tube from being inserted too deep accidentally, thereby avoiding accidents.

[0004] Most of the existing nasal sprayers are used to spray medicine into the patient's nasal cavity, usually by spraying the medicine liquid directly from the spray head through the spray device. However, during actual use, the sprayed medicine will be blocked by the nasal hair inside the nasal cavity, so that the medicine cannot reach the nasal cavity completely, resulting in partial waste of the medicine effect and increased treatment time. In addition, some existing devices use disposable spray heads to prevent users from cross-infection, but they are simply snap-fitted and fixed during use. When spraying the medicine, excessive force will spray the spray head together, causing certain damage to the nasal cavity. In addition, the nasal cavity is easily irritated at the moment of spraying, causing sneezing. If it is blocked, snot and medicine will fly everywhere.

[0005] Therefore, a medicine sprayer for nasal cavity is proposed in view of the above problems. Utility Model Content
