Be provided with the obturator on the sealed pad 2323, keep away the hole and set up to the blind hole, through-hole 2325 and obturator distribute along mounting groove 2326 direction, after the endoscope uses or when needs wash, draw back insert portion 12, the soft cover 3 of protection stretches out, in insert portion 12 drawing back the in-process, the attachment of insert portion 12 outer wall can be scraped by the doctor-bar and take off, stay between doctor-bar and sealed pad 2323, when the head end 122 of insert portion 12 returns sealed pad 2323 rear side, can promote push pedal 2322 so that obturator seals up the passageway of pipe 2311 and lower pipe 2312, can wash this moment.
Referring to fig. 4 and 9, the flushing assembly 24 includes a flushing connector 241 and a sealing cap 242, after the sealing pad 2323 is closed, a containing groove 25 for containing the attachment of the insertion portion 12 is disposed between the wiper blade and the sealing pad 2323, one end of the flushing connector 241 is communicated with the containing groove 25, and the other end is sealed by the sealing cap 242, and the flushing connector 241 is used for connecting flushing liquid when flushing is performed. When the endoscope is used and needs to be cleaned, i.e. after the switch pad is closed, the attachment on the outer wall of the insertion part 12 is remained in the accommodating groove 25 between the scraping blade and the sealing pad 2323, the accommodating groove 25 forms a closed cavity, the required flushing liquid is connected into the flushing inlet, and meanwhile, the suction interface 111 on the endoscope operation part 11 is used, and the foreign matters in the accommodating groove 25 can be diluted, extracted and discharged through the opening of the working channel 112 on the head end 122.
The implementation principle of the technical scheme is as follows: referring to fig. 1, before the endoscope is used, a protective soft sleeve 3 is sleeved on an insertion part 12, and an operation joint 2 is positioned at the front end of the insertion part 12; referring to fig. 3, when the endoscope is in use, the push plate 2322 is pushed to drive the sealing pad 2323 to move, so that the through hole 2325 is communicated with the upper tube 2311 and the lower tube 2312 at two ends, the insertion part 12 extends out of the joint assembly 22, the protective soft sleeve 3 at the outer side of the insertion part 12 contracts and folds, the part of the insertion part 12 extending out of the joint assembly 22 extends into a human body, the non-extending insertion part 12 is positioned in the airtight space of the protective soft sleeve 3, and at the moment, an instrument can normally enter the human body along the insertion part 12 from the working channel 112 for examination and treatment.
Referring to fig. 9, after the endoscope is used, the insertion portion 12 is withdrawn, the protective film sleeve is stretched and unfolded, the protective soft sleeve 3 always covers the insertion portion 12, and during the withdrawal of the insertion portion 12, the attachments on the outer wall of the insertion portion 12 are scraped off by the wiper blade and remain outside the wiper blade, and the head end 122 of the insertion portion 12 is not pulled away from the wiper blade because the length of the insertion portion 12 is greater than the length of the protective film; when the head end 122 of the insertion part 12 retreats to the rear side of the sealing pad 2323, the push plate 2322 is pushed to enable the upper pipe 2311 and the lower pipe 2312 to be closed through closed hole isolation, at the moment, the scraped attachments of the insertion part 12 are remained in the containing groove 25 between the scraping blade and the switch pad, and the containing groove 25 forms a closed cavity; and after the sealing gasket 2323 is closed, the scraping blade component 21 and the switch component 23 can be quickly separated, and breathing equipment connected to the connector component 22 can be normally supplied.
Referring to fig. 1 and 9, when the accommodating groove 25 is flushed, a required flushing liquid is introduced into the flushing inlet, and simultaneously, the suction port 111 on the endoscope operation part 11 is used, the flushing liquid enters the accommodating groove 25 for diluting flushing and enters the main hose 121 along the head end 122 of the insertion part 12, and finally, the liquid is discharged from the suction port 111.
In the embodiment of the application, the design of the protective soft sleeve 3 always places the insertion part 12 of the endoscope in a closed use environment, so that the infection risk of the foreign matters discharged by a patient to staff is reduced; realize the isolation protection in the whole processes of use, cleaning, turnover or scrapping, etc. The endoscope in the scheme can be a repeated endoscope and can also be used for closed protection of the disposable endoscope; when the endoscope is used for a disposable endoscope, the risk of cross infection in the disposal process of the endoscope can be avoided.
The foregoing description of the invention has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the invention pertains, based on the idea of the invention.
