Description

A quantity-controlled humidification and heating laryngostomy filter protective cover

Technical field

The invention relates to the technical field of medical equipment, and in particular to a volume-controlled humidifying and warming laryngostomy filter protective cover.

Background technique

Laryngeal cancer is a common malignant tumor in otolaryngology. Current clinical treatment of laryngeal cancer mainly adopts surgical treatment. Total laryngectomy patients need to wear a tracheal tube for a long time, and the laryngostomy remains for life. The patient loses the role of the nose in warming, humidifying, and blocking dust in the air. Gas exchange will cause various complications, such as increased airway water loss. , sputum scabs in the tracheal tube or stoma, inhalation of foreign bodies, cold air stimulation, fistula infection, etc. In the postoperative care of patients with laryngeal cancer, airway care is the focus of care. Continuous humidification, clean environment, and prevention of dust inhalation are the focus of care. During care, it is ensured that the patient's airway is continuously humidified, and the amount of sputum coughed up and the amount of sputum produced by the patient are ensured. The symptoms are checked and cleaned in a timely manner; hospital infection monitoring is strengthened to control the risk of patient infection; dressings are changed in time every day, and throat cannulas are replaced regularly, so that the infection rate of patients is low and the patient's comfort is good. Patient compliance is high during postoperative care, which effectively prevents postoperative complications.

When discharged from the hospital, nurses will strengthen education and instruct patients to drink more water to replenish the amount of fluids, maintain the physiological humidification state of the respiratory tract, and reduce the viscosity of sputum to facilitate spontaneous coughing. Or use a household atomizer to help patients improve the temperature and humidity of the air, and wear a gauze around the neck to block dust. Discharge education guidance on air requirements, airway humidification requirements, environmental requirements, management requirements, etc. is clear. Despite the guidance of medical staff, self-management after discharge is still difficult. Due to limited equipment and family environment after discharge, it is often difficult to persist. After the patient leaves the hospital, due to the need for continuous humidification to prevent complications, the patient spends most of his time at home, which has a great impact on the patient's quality of life. At the same time, patients have poor self-care ability and lack tools for airway management; long-term stoma exposure leads to dry airways and poor comfort; the exposed stoma loses a huge amount of invisible water, forms stoma scab, affects ventilation, and causes viscous phlegm. Sputum cannot be discharged, fine dust invades and irritates the respiratory tract, environmental pollution and local infection rates are high, which has a significant impact on life.

Laryngostomy is the only ventilation port for patients after total laryngectomy. How to protect the stoma and prevent complications is an urgent problem that patients need to solve. It is also a prerequisite for patients to return to their families and society and improve their quality of life. How can we help laryngostomy patients solve the problem? Have an artificial filter to help filter the air and prevent dust; have a portable humidifier to increase air humidity; have a comfortable thermostat to avoid irritating cold air ; Having a breathable membrane that can be replaced at any time to avoid sputum contamination and ensure smooth laryngostomy is worthy of our medical staff’s consideration and efforts.

Contents of the invention

The object of the present invention is to propose a volume-controlled humidification and warming laryngostomy filter protective cover with good humidification and heating effect, good stability and sustainable high-efficiency filtration in view of the above-mentioned shortcomings of the prior art.
