Pressure equalizing protective oxygen humidification bottle for an operating room

Abstract

The invention discloses a pressure equalizing protective oxygen humidification bottle for an operating room. The pressure equalizing protective oxygen humidification bottle comprises a humidifying bottle and a moisturizing bottle arranged side by side. A bottle cap is arranged on the top of the humidifying bottle. A hollow connection base is arranged between a flowmeter and the bottle cap. A pressure equalizing pipe connected with both of the connection base and the flowmeter is inserted to the side face of the connection base. A pressure equalize is arranged at the front end of the pressure equalizing pipe. The pressure equalizer comprises two branch pipes butted with the front end of the pressure equalizing pipe, and a conical plug is arranged at the front end of each branch pipe. According to the invention, through arranging the pressure equalizer connected to the humidifying bottle by the pressure equalizing pipe, the pressure on both sides of an ear tympanic membrane of a patientis always kept consistent during a pressurized delivery process of oxygen, thereby avoiding possible damage to the ear tympanic membrane due to the pressure difference of the ear tympanic membrane during pressurized delivery of oxygen. Therefore, the safety of oxygen therapy during the operation is improved. Because of the effect of the tympanic membrane, the pressure on both sides of the tympanicmembrane is balanced and a condition that the outer side of the tympanic membrane receives larger pressure is avoided.

Description

technical field [0001] The invention relates to a medical appliance in an operating room, in particular to a pressure-equalizing protective oxygen humidification bottle for the operating room. Background technique [0002] Oxygen infusion is a method of using an oxygen tube or an oxygen mask to deliver oxygen under pressure so that the patient can inhale oxygen; its main function is to increase the partial pressure of arterial oxygen, improve the oxygen supply of the human body, and reduce the burden of breathing and circulation caused by compensatory hypoxia. [0003] In the operation, it is one of the commonly used rescue treatment for hand injury when inhaling oxygen. The oxygen cylinder used for medical oxygen storage is compressed dry oxygen. When the patient directly inhales it, it will cause discomfort in the respiratory tract. Currently, there are A humidification bottle is used to ensure that the oxygen is humidified during the oxygen delivery process, so as to prev...

AI Technical Summary

Problems solved by technology

During the operation, the patient is under anesthesia, and the ability to breathe spontaneously decreases. When oxygen is delivered, the oxygen pressure will increase for delivery. Due to the function of the human body, when the pressure in the oral cavity increases, the pressure on the inner side of the eardrum will increase synchronously. Prolonged high-pressure state may cause damage to the patient's eardrum
