Description

endoscope isolation sleeve

The present invention relates to an isolation sleeve, in particular to an endoscope isolation sleeve for in-vivo inspection.

Endoscopy is mainly used in the medical field. Doctors can pass a catheter of the endoscope through the patient's mouth and extend it into the human body, and observe the condition of the patient's internal organs through a camera lens on the endoscope. View small and unobservable locations, allowing physicians to further examine and diagnose the patient's condition.

However, during the direct invasive in-vivo examination of the endoscope, objects such as skin flakes, body fluids or cells of the patient will come into contact with the catheter. Even if the medical staff cleans and disinfects the endoscope afterwards, it will It is difficult to ensure that there is no residue on the endoscope, so it is easy to cause the problem of cross-infection between the patient and the next patient; and during the inspection process, if the doctor wants to treat the affected part of the patient, it is necessary to additionally set up a Only machines and equipment with a drug-adding channel can deliver drugs such as anesthetics or therapeutic agents to the affected part. However, machines and equipment with drug-adding channels are usually very expensive, which not only provides poor treatment convenience, but also makes it difficult to reduce operating costs.

In view of this, it is still necessary to improve the conventional endoscopy methods.

In order to solve the above-mentioned problems, the purpose of the present invention is to provide a kind of endoscope isolation sleeve, which is It can prevent patients from cross-infection and improve the convenience of treatment.

Another object of the present invention is to provide an endoscope isolation sleeve, which can improve the convenience of operation.
