Description

TECHNICAL FIELDThe invention relates to the technology of medical devices, in particular a sealing flap or endoscopic face mask provided with an adjustable aperture.BACKGROUNDAn endoscopic face mask is used in gastroscopy and fiber optic tracheaoscopy. During the examination, the endoscopic face mask can inhale a patient with oxygen or anesthetic gas through the lateral openings, so that an intubation and an respiration of the patient can take place simultaneously. However, the sealing between the face mask and the endoscope must be taken into account.As a rule, the examination requirements are different depending on the patient, so that different diameters of endoscopes are to be available. However, in the prior art, the face masks available on the market can only adapt to a single specification of endoscopes. In this case, the doctor needs to examine the specification of a face mask to be used before surgery whether it conforms to each endoscope, which is inconvenient for the clinician and may impair the working efficiency.DESCRIPTION OF THE UTILITY MODELBased on the shortcoming of the conventional technique, the object of the invention is to provide an adjustable aperture sealing flap or an endoscopic face mask, which can adapt to endoscopes of various specifications and thus enhance performance.To achieve the object, there is provided an adjustable aperture sealing flap comprising a base, a flap body detachably mounted on the base, and a sealing kit compatible with endoscopes of various specifications and having one end positively pressing the flap body while the other end fixedly fitting on the base.In certain embodiments, the sealing set comprises a membrane and an inner rotating bushing acting to carry along the membrane, and an outer rotating bushing, wherein the inner rotating bushing is rotatably mounted at one end on the flap body and is connected at the other end to the outer rotating bushing, while the membrane is connected at one end to the outer rotating bushing and at the other end to the base.In certain embodiments, the inner rotating sleeve and the outer rotating sleeve are all circular, with the upper end of the membrane fixed between the inner rotating sleeve and the outer rotating sleeve.In certain embodiments, the inner rotary bushing and the outer rotary bushing are all made of a plastic.In certain embodiments, a convex ring is attached to the lower end of the diaphragm for receiving a corresponding mounting groove formed in the base.In certain embodiments, a collar is formed at the bottom of the base that remains complementary with the valve body to clamp the endoscopic face mask.In certain embodiments, a buffer disk is attached to the top of the collar.In certain embodiments, the buffer disc is made of silicone and / or rubber.To achieve the object, an endoscopic face mask is further provided, which comprises a mask body and a sealing flap provided with an adjustable aperture.Optionally, a mounting platform can also be mounted outside the mask body, one end of which platform presses against the buffer disc and the other end of which platform presses against the flap body.The utility model has the following advantages:1.In the sealing flap according to the invention, the two ends of the sealing set, comprising a membrane and an inner rotary bushing acting to carry along the membrane and an outer rotary bushing, are each connected to the base and to the flap body. When the rotary bushes are rotated, the other end of the membrane is entrained for rotation because one end of the membrane is fixed, so that a hole for shrink-fitting clamping of the endoscope is formed in the central point of the membrane. Here, the aperture of the hole changes correspondingly depending on the change in the rotation angle of the rotary bushes, so that the aperture setting can adapt to endoscopes of different specifications.2. With the sealing flap according to the invention, a specific mask body can be suitable for endoscopes of different specifications, which facilitates the adaptation activities of the clinicians and thus improves the working efficiency.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a sectional view of the adjustable aperture seal door of the present invention; FIG. 2 is a partial view of the view in FIG. 1 ; FIG. 3 is a sectional view of the mask body according to the present invention; FIG. 4 is a partial view of the view in FIG. 3 ; Fig. 5 shows a view of the complete structure of the utility model.DETAILED DESCRIPTION OF EMBODIMENTSFurther objectives, advantages, features and possible applications of the utility model will become apparent from the following description of the exemplary embodiments with reference to the drawings.

In this connection, the embodiment of the present invention is not limited to these positional terms. Hereinafter, the present invention will be described in detail based on the embodiments and drawings.Referring to Figs. 1 to 4, the sealing flap according to the invention comprises a base 1, a flap body 2 which is detachably mounted on the base 1, and a sealing kit 3 which is compatible with endoscopes of various specifications and one end of which positively presses on the flap body 2 while the other end thereof is fixedly seated on the base 1.In the present embodiment, the flap body 2 is detachably mounted on the base 1. The valve body 2 connected to the base 1 can then be connected to the endoscopic face mask. The both ends of the sealing kit 3 are respectively connected to the base 1 and the valve body 2 to lock various endoscopes of different specifications. With this arrangement, an endoscopic face mask can adapt to endoscopes of various specifications only via a sealing flap, which facilitates the adaptation activities of the clinicians and thus improves the working efficiency.It can furthermore be configured that the sealing set 3 has a membrane 31 and an inner rotary bushing 32 acting for driving the membrane 31 as well as an outer rotary bushing 33, wherein the inner rotary bushing 32 is rotatably mounted with one end on the flap body 2 and is connected with the other end to the outer rotary bushing 33, while the membrane 31 is connected with one end to the outer rotary bushing 33 and with the other end to the base 1.In the present embodiment, the inner rotary bush 32 is rotatably attached to the upper end of the door body 2, while the outer rotary bush 33 is attached outside the inner rotary bush 32. In addition, one end of the diaphragm 31 is fixed to the outer rotary bush 33, and the other end is fixed to the base 1, so that the inner rotary bush 32 and the outer rotary bush 33 can carry the upper end of the diaphragm 31 for rotation.When the rotary bushes are rotated, the other end of the membrane is entrained for rotation because one end of the membrane is fixed, so that a hole for shrink-fitting clamping of the endoscope is formed in the central point of the membrane 31. The aperture of the hole in the diaphragm 31 changes accordingly depending on the change in the angle of rotation of the rotary bushes, so that the hole can have the following shapes:1 starting position with the largest hole; 2 aperture in 29 mm when the rotary bushes are rotated by about 30°; 3 aperture in 15 mm when the rotary bushes are rotated by about 90°; 4 aperture in 10 mm when the rotary bushes are rotated by about 120°; 5 aperture in 5 mm when the rotary bushes are rotated by about 160°; 6 closed hole when the rotary bushes are rotated by about 180°.The larger the rotation angle of the turning cams, the smaller the aperture of the hole. As a result, various holes of various apertures can be formed in the diaphragm 31 to enable the seal set 3 to conform to endoscopes of various specifications via variable apertures, thus achieving easy operability, easy adjustment and high accuracy.It may be further configured that the inner rotating bush 32 and the outer rotating bush 33 are all circular, and the upper end of the diaphragm 31 is fixed between the inner rotating bush 32 and the outer rotating bush 33.In the present embodiment, the inner rotary bush 32 and the outer rotary bush 33 may be all formed in a circular shape so that the inner bush can take the diaphragm 31 to smoothly rotate around the outer periphery of the door body 2. At this time, the upper end of the diaphragm 31 is fixed between the inner rotary bush 32 and the outer rotary bush 33 to sandwich the diaphragm 31.It can furthermore be configured that the inner rotary bushing 32 and the outer rotary bushing 33 are all made of a plastic.In the present embodiment, the inner rotary bush 32 and the outer rotary bush 33 are all formed as a round bush made of plastic, which brings about low production costs, lower weights and suitability for medical devices.It can also be configured that a convex ring 41 is attached to the lower end of the membrane 31, for receiving a corresponding mounting groove 42 in the base 1.In the present embodiment, a convex ring 41 is attached to the lower end of the diaphragm 31. For this purpose, a corresponding mounting groove 42 is formed in the base 1. In the successful mounting state of the convex ring 41 in the mounting groove 42, the outside of the lid body 2 will press the convex ring 41 to the base 1 (see FIG. 2 ). As a result, the lower end of the diaphragm 31 is fastened in a robust manner in order to prevent any slipping or displacement of the diaphragm 31 during operation.It may be further configured that at the lower end of the base 1 a collar 51 is formed which remains complementary with the valve body 2 to clamp the endoscopic face mask.In the present embodiment, a collar 51 is formed at the lower end of the base 1. In the successful mounting state of the valve body 2 on the base 1, a clamping mechanism for clamping the endoscopic face mask is formed between the valve body 2 and the collar 51 (see FIGS. 3 and 4 ), so that the complete sealing valve can be attached to the endoscopic face mask.It can also be configured that a buffer disk 52 is attached to the upper side of the collar 51, said buffer disk being manufactured from silicone and / or rubber.In the embodiment shown, a buffer disc 52 is attached to the upper side of the collar 51, which buffer disc can be made of silicone and / or rubber. The buffer washer 52 can buffer the clamping of the endoscopic face mask between the valve body 2 and the collar 51 in order to protect the endoscopic face mask from injury and to achieve a robust connection between the base 1 and the face mask, on the one hand, and to fill the gap between the collar 51 and the face mask, on the other hand. This ensures the tightness between the sealing flap and the endoscopic face mask.Referring to Figs. 3 to 5, an endoscopic face mask is shown which comprises a mask body 6 and an adjustable aperture sealing flap. Here, a mounting platform 7 is mounted outside the mask body 6, one end of which platform presses against the buffer disc 52 and the other end of which platform presses against the flap body 2.In the present embodiment, the seal door can be fixed to the mask body 6 via the clamping mechanism for clamping the endoscopic face mask between the base 1 and the door body 2. Here, outside the mask body 6, such a mounting platform 7 is attached, one end of which presses against the buffer disk 52 and the other end of which presses against the flap body 2 (see FIG. 4 ), so that the clamping mechanism can be fixed to the mounting platform 7 in order to bring about a buffed connection between the mask body 6 and the sealing flap provided with an adjustable aperture.Furthermore, a centering mechanism (such as a collar-recess arrangement for positioning) is provided between the base 1 and the mounting platform 7, which centering mechanism positions the base 1 in position relative to the mounting platform 7 and can thus prevent the sealing set from co-rotating when the base 1 rotates. This ensures the stable fixing of the base 1 during operation of the sealing kit.The sealing flap or endoscopic face mask provided with an adjustable aperture according to the invention can advantageously adapt to endoscopes of different specifications and thus increase the performance.The preferred embodiments of the invention are described above. It should be noted that the utility model is not limited to the exemplary embodiments, but rather can be widely variable within the scope of the disclosure. In this context, all new individual and combination features disclosed in the description and / or drawing are considered to be essential to the invention.List of reference numbers:1 Base 2 Flap body 3 Sealing set 31 Diaphragm 32 Inner rotating bush 33 Outer rotating bush 41 Convex ring 42 Mounting groove 51 Collar 52 Buffer disk 6 Mask body 7 Mounting stage
