Oxygen humidification bottle

Abstract

The invention discloses an oxygen humidification bottle which is safe to use, stable in structure and convenient for clinical operation. The oxygen humidification bottle is technically characterized by comprising a bottle body with an inlet and an outlet and a humidifying tube arranged in the bottle body, one end of the humidifying tube is communicated with the inlet, and a switch block which synchronously controls the humidifying tube to be communicated with the inlet and the outlet to be closed is arranged in the bottle body. Smoothness of an oxygen inlet and outlet passage in the bottle body is guaranteed so as to ensure pressure in the humidifying bottle cannot accumulate or increase sharply due to clinical misoperation or mechanical breakdown of an air anti-reflux device, explosion caused by sharp increase of the pressure of the humidification bottle is avoided, pressure of the humidification bottle in the whole oxygen uptake process is kept in a reasonable and safe range, safety in use of the oxygen humidification bottle is ensured, and risk of clinical use is lowered greatly; besides, service life of the switch block is guaranteed as the switch block cannot bear high pressure due to quick outflow of oxygen.

Description

technical field [0001] The invention relates to a medical device, more specifically to an oxygen humidification bottle. Background technique [0002] Oxygen inhalation is one of the commonly used rescue or treatment methods in hospitals. Since the artificially prepared medical oxygen is extremely dry, direct inhalation of medical oxygen will cause dryness and discomfort to the patient's respiratory tract. Therefore, oxygen humidification has become an essential part of the oxygen inhalation process for patients. In the past, hospitals generally used reusable oxygen humidification bottles. This product has been used for many years. The main problem is that it is easy to be polluted and the safety is relatively poor. Even the new integrated oxygen humidification bottle has been solved. However, in order to ensure that the humidification liquid in the humidification bottle will not be polluted by the air in the hospital before use and during the stop of oxygen inhalation, the m...

Problems solved by technology

In the past, hospitals generally used reusable oxygen humidification bottles. This product has been used for many years. The main problem is that it is easy to be polluted and the safety is relatively poor. Even the new integrated oxygen humidification bottle has been solved. However, in order to ensure that the humidification liquid in the humidification bottle will not be polluted by the air in the hospital before use and during the stop of oxygen inhalation, the measures currently taken are to install a sealing device at the oxygen inlet and outlet and Install an air counterflow device at the air outlet to prevent the invasion of foreign bacteria

However, after using this device, the air counterflow device at the oxygen outlet affects the flow of oxygen and increases the resistance of oxygen discharge, thereby increasing the pressure in the humidification bottle. When the sealing device at the place is not opened due to the negligence of the medical staff, it is very easy to cause the pressure accumulation or sharp increase in the humidification bottle due to mechanical failure or improper operation, resulting in the explosion of the oxygen humidification bottle, so there is a certain clinical application Potential safety hazards, and increase the workload of medical staff
