Description

Accurate administration equipment of thoracic surgery atomizing treatment Technical Field The invention belongs to the technical field of atomization treatment of thoracic surgery, and particularly relates to accurate drug delivery equipment for atomization treatment of thoracic surgery. Background In clinical treatment of thoracic surgery, atomized administration is a key auxiliary treatment means for diseases such as lung cancer postoperative, chronic obstructive pulmonary combined pulmonary infection, chest trauma pulmonary atelectasis and the like, and the key aim is to realize the treatment effects of diluting sputum, resisting inflammation, relieving asthma and promoting pulmonary function recovery by atomizing the medicine into tiny particles which are accurately delivered to the airway and the lung of a patient. However, there are still a number of technical drawbacks with the currently clinically applied nebulized drug delivery devices, which are difficult to meet the precise therapeutic needs of patients with chest surgery, the specific pain points are as follows: 1. The medicine feeding accuracy is insufficient, the medicine conveying controllability is poor, the medicine feeding structure of the traditional atomizing equipment adopts a direct dumping or simple syringe pushing mode, a stable transmission control mechanism is lacked, and the medicine pushing dosage and speed cannot be accurately regulated. The patient with chest surgery has weak postoperative body, larger tolerance difference to the drug dosage, ineffective treatment caused by insufficient dosage and possible adverse reaction caused by excessive dosage, and meanwhile, the non-uniform drug pushing is easy to cause atomization concentration fluctuation, thereby affecting the absorption efficiency of the airway on the drug and reducing the treatment effect; 2. The airway conditions of different thoracic surgery patients are different (such as the degree of postoperative airway edema and the viscosity of sputum), and the requirements for the particle size of the atomized medicine are different. The filter screen of traditional atomizing equipment is mostly fixed aperture design, can't adjust atomizing particle size according to patient's actual conditions, and too big granule is easily deposited at the air flue entry, can't reach pathological change position, and too little granule then probably runs off along with exhaling, reduces medicine utilization ratio. Based on the clinical pain point, the accurate administration equipment for the thoracic surgery atomization treatment, which is accurate and controllable in administration, safe and sanitary in use, flexible in atomization particle size adjustment and strong in stability, is developed, and becomes an urgent requirement for improving the thoracic surgery atomization treatment effect and guaranteeing the safety of patients.
