Description

Technical Field

[0001] The invention relates to the technical field of otolaryngology and rhinology medicine applicators, in particular to an otolaryngology and rhinology nasal medicine applicator. Background Art

[0002] In the field of modern medicine, the treatment of otolaryngology diseases has always attracted much attention, among which the treatment of nasal diseases occupies an important position. As an important part of the human respiratory tract, the nasal cavity has a complex internal structure and is easily affected by various factors and causes various diseases, such as rhinitis, sinusitis, nasal polyps, etc. In the treatment of nasal diseases, accurately and effectively applying medicine to the inside of the nasal cavity is one of the key links. However, traditional nasal medicine application methods have many limitations and shortcomings. In the past, common nasal medicine application methods mostly relied on simple tools such as cotton swabs and droppers. When using cotton swabs to apply medicine, it is often difficult to evenly apply the medicine to the inner wall of the nasal cavity, and it is easy to damage the nasal mucosa, causing discomfort to the patient or even aggravating the condition. Although the dropper application can control the outflow of the medicine to a certain extent, due to the sharp tip of the dropper, improper operation may also cause damage to the nasal cavity. In addition, some existing nasal medicine application devices lack humanized considerations in design. For example, their size and shape may not be suitable for different The difference in the physiological structure of the patient's nasal cavity leads to poor fit during use, which affects the effect of medication. Moreover, these devices are often cumbersome to operate and require professional training to master. This not only increases the workload of medical staff, but also makes it difficult for patients to apply medication by themselves. In terms of drug delivery and distribution, traditional devices also have problems. The drug may not accurately reach the lesion site or be unevenly distributed in the nasal cavity, thereby reducing the effectiveness of treatment. At the same time, some medication devices cannot accurately control the dosage of the drug, resulting in overdose or underdose, affecting the treatment effect. At the same time, during the medication process, some drugs are irritating and will irritate the patient's nasal cavity. Therefore, during the spraying of the drug, the operator cannot feel the patient's tolerance limit to the drug, which may easily lead to the patient's intolerance and uncontrolled head movement during the spraying process, and it is easy to cause the medication device to break inside the patient's nasal cavity or puncture the patient's nasal mucosa, posing a major safety hazard. Summary of the invention

The universal fixed braces are clamped and fixed to the patient's upper teeth, so that the applicator can be fixed relative to the patient's head. No matter how the patient moves his head during the operation, the applicator located inside the patient's nasal cavity will not damage the patient's nasal cavity, which greatly improves the safety of the operation; Furthermore, the bite plate is squeezed by the patient so that the bite plate can contact and pressurize the lower surface of the universal fixed braces through the pressurized bag, so that the liquid in the liquid storage cavity can be sprayed into the liquid at a speed controlled by the patient, thereby achieving the purpose of the patient spraying the liquid according to his own tolerance. Furthermore, the liquid storage chamber is designed with a certain capacity to ensure that the amount of liquid medicine sprayed into the nasal cavity each time can be controlled, and excessive spraying due to operating errors will not occur. At the same time, the spray holes arranged in a rotation direction drive the spray barrel column to rotate through the reaction force during the spraying process, so that the liquid medicine can be sprayed more evenly inside the patient's nasal cavity; 2. The relative sliding and rotation between the mounting plate, mounting rod and angle rod allows the spray barrel column to be adaptively adjusted according to the position of the patient's nasal cavity relative to the upper jaw, to ensure that different patients can use it without customization, thereby improving the versatility and applicability of the medicine applicator.
