Description

Freely-replaceable disinfection and filtration structure for medical breathing machine Technical Field The utility model relates to the technical field of respirators, in particular to a freely replaceable disinfection and filtration structure for a medical respirator. Background In modern clinical medicine, a respirator is used as an effective means capable of replacing autonomous ventilation by manpower, is widely used for respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation, and occupies a very important position in the field of modern medicine. The breathing machine is a vital medical device which can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. The breathing joint of the existing breathing machine is mainly installed through a connecting mode of plug and pull, the breathing joint is convenient to install, but is not firm to install, is easy to loosen, further influences the effect of air supply, and is convenient to install and free to replace, meanwhile stability after installation is guaranteed, and therefore the problem of the medical breathing machine in the prior art is solved through a disinfection and filtration structure capable of being freely replaced. Disclosure of utility model 1. Technical problem to be solved Aiming at the problems in the prior art, the utility model aims to provide a freely replaceable disinfection filter structure for a medical breathing machine, which ensures the stability of filter installation, can effectively prevent the loosening of the filter, can ensure the normal transportation of gas, and is convenient and free to replace by reversely screwing a locking sleeve to separate from the constraint of a claw when the filter needs to be replaced and then taking the filter off from a breathing joint. 2. Technical proposal In order to solve the problems, the utility model adopts the following technical scheme. The utility model provides a but medical treatment breathing machine is with disinfection filtration that freely changes, includes the breathing machine body, installs breathing joint on the breathing machine body and with the filter that the breathing joint is butted, the both ends of filter all switch on and are connected with the connector that is tubular structure setting, the breach has been seted up to the tip of connector, just the breach is in the radial position of connector is provided with a plurality of, the inboard of breach be provided with connector integrated into one piece's jack catch, the end orientation of jack catch the inboard position integrated into one piece of connector has the joint, the tip of jack catch is kept away from the surface integrated into one piece of joint has the inclined plane that is the elevation angle structure setting, the external screw thread has been seted up to the connector with the outer wall of jack catch; The outside cover of connector is equipped with the lock sleeve, the inner wall of lock sleeve seted up with the internal thread of external screw thread looks spiro union.
