Description

A kind of mouth-biting nursing device used for relieving ulcer of oral mucosa of patient during chemotherapy

Technical Field

The invention relates to the technical field of medical instruments, in particular to a mouth-biting nursing device for relieving oral mucosa ulcer of a patient during chemotherapy.

Background

Nausea, vomiting and alopecia are well known as toxic and side effects of radiotherapy and chemotherapy, but in fact, many cancer patients have a trouble in radiotherapy and chemotherapy, namely inflammation of oral mucosa and oral pain. According to relevant clinical statistics, severe oral mucositis occurs in about 40% of patients with head and neck cancer who receive chemotherapy. In the process of receiving radiotherapy and chemotherapy, a nerve conduction substance in a human body can cause mucous membrane inflammation after being combined with a nerve receiver, so that the patient has dry mouth, oral cavity pain, dysphagia, dysphasia and the like, and serious ulcer and even suppuration of the oral cavity can be caused. Furthermore, it is difficult to eat food due to oral pain, and in the past, insufficient intake of nutrients, weight loss, and the like have occurred.

At present, in order to alleviate the problems caused by the inflammation of the oral mucosa of chemotherapy patients, physical methods and chemical methods are generally adopted for nursing the oral cavity, and the physical methods mostly adopt low-temperature and laser therapies. The cold stimulation is used at low temperature in the oral cavity, the blood vessels of the mucous membrane in the oral cavity are contracted, the oxygen content of the mucous membrane tissue is reduced, and the reaction of chemotherapy to the mucous membrane is reduced, so that the mucous membrane in the oral cavity is protected. The chemical method is to gargle the compound gargle and combine with vitamin B12 mixture and Beifuji spray for treatment, and is selected from a plurality of aspects of relieving pain, preventing and controlling infection, relieving injury, improving oral environment, promoting wound healing and the like. The preparation method comprises directly administering bioactive drugs such as granulocyte-macrophage colony stimulating factor, basic fibroblast growth factor, and recombinant human epidermal growth factor to promote the repair of oral ulcer. In the actual nursing process, atomization treatment and gargling pain relief are generally performed alternately, and in the gargling pain relief process, the gargle of a patient can cause muscle stiffness of the oral cavity of the patient to generate obvious uncomfortable feeling, so that the applicant researches a nursing device which can give consideration to both atomization treatment and gargling pain relief and can avoid the problem of the muscle stiffness of the oral cavity of the patient caused in the gargling pain relief process.
