Description

Laryngeal cancer patient atomizing drug delivery device

Technical Field

The invention relates to the field of atomizers, in particular to an atomized drug delivery device for a laryngeal cancer patient.

Background

For laryngeal cancer patients, conventional oral drug administration may present difficulties such as dysphagia, stomatitis, etc. Therefore, how to safely and effectively deliver drugs to a focal site is a highly desirable problem. Thus, techniques for nebulized administration to laryngeal cancer patients have evolved. The method can greatly reduce degradation of the medicine in gastrointestinal tract, and improve bioavailability of the medicine. In addition, the atomized medicine can directly send the medicine to the focus through a fine air flow, so that the occurrence of side effects is reduced. To ensure patient safety, we also need to pay attention to the following points:

1. during nebulization, the appropriate nebulizer should be selected according to the patient's condition and the nature of the drug. Different types of nebulizers are suitable for different kinds of drugs.

2. Patients were carefully evaluated to ensure that they could safely use the nebulizer. This includes examining their respiratory function, lung capacity, degree of lung lesions, etc.

3. Before the patient can be subjected to the aerosolized administration procedure, the procedure and the possible side effects need to be explained in detail to eliminate the stress and fear of the patient.

4. Patients were followed regularly to monitor the efficacy and adverse effects of the drug in order to adjust the treatment regimen.

For lung cancer patients, we will typically choose a nebulizer with a larger drop volume so that more drug can be delivered into the bronchi. At the same time, we will choose the atomizer according to the property of the medicine, for example, for some medicines easy to oxidize, we need to choose the atomizer with antioxidant function to ensure the effectiveness of the medicine.

For laryngeal cancer patients, traditional nebulizers may not be able to accurately deliver drugs to the lesion site due to the severe lesions of the laryngeal. At this time, we will choose a nebulizer with a special design that can adapt to the laryngeal structure, such as a laryngeal dilator specially used for laryngeal cancer treatment, etc.

For patients with oral cancer, it is desirable to select a nebulizer that produces enough foam in the oral cavity so that the drug dissolves well in the mouth and then reaches the esophagus.

The atomizing administration device on the market only can adapt to single patient at present, and the suitability is relatively poor, and in atomizing process, the primary inhalation liquid medicine pungency is great, can bring uncomfortable feeling for the patient.
