Medical ventilator with sterilization function and convenient to replace

Abstract

The invention relates to a medical ventilator with a sterilization function and convenient to replace. The medical ventilator comprises a base, an air tube, an oxygen tube, a main body, a sealing mechanism, a sterilization box, an air guiding tube, an inhalation tube, an exhalation tube, a connector and a respiratory mask. The sterilization box is provided with a sterilizing mechanism. The sealingmechanism comprises a sealing plate, a driving assembly, a telescopic frame, two moving blocks and two connecting rods. The sterilizing mechanism comprises a sterilizing tube, a first motor, a rotating disc, a fixing assembly and a plurality of sterilizing assemblies. An ultraviolet lamp tube in the sterilizing mechanism rotates to uniformly irradiate the air in the sterilizing tube with ultraviolet rays to achieve the aim of sterilization and provide the sterile air for patients to ensure respiratory health of the patient. In addition, the sealing mechanism can protect the sterilization boxfrom dust and seal the box, and the sterilization box can be opened to conveniently replace a lamp casing and the ultraviolet lamp tube. Long-term use of the ventilator can be ensured, and the practicability of the ventilator is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an easy-to-replace medical ventilator with sterilization and disinfection functions. Background technique [0002] In modern clinical medicine, medical ventilator, as an effective means of artificially replacing the function of spontaneous ventilation, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation , occupies a very important position in the field of modern medicine. Medical ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] However, when the existing medical ventilator is in use, the external air and oxygen are mixed and humidified by the humidifier, and then directly passed into the mouth and nose of the patient. Because the ventilator ...

Problems solved by technology

[0003] However, when the existing medical ventilator is in use, the external air and oxygen are mixed and humidified by the humidifier, and then directly passed into the mouth and nose of the patient. Because the ventilator is often used in the ward of the hospital, the air in the ward There are usually all kinds of bacteria and viruses in the environment. When patients use the ventilator, they usually inhale the bacteria and viruses, which affects the patient's health and delays the recovery of the patient, thus reducing the practicability of the existing medical ventilator.
