The key 21 that can process arbitrarily type is equipped with in access portal portion 17.As shown in Figure 2, access portal portion 17 has clasp 20.Via this clasp 20, key 21 is installed on access portal portion 17.It should be noted that, in the following description, as shown in Figures 2 and 3, with the clasp 20 in access portal portion 17 state upward for benchmark, each portion of key 21 is described, installation side and lower portion are called bottom, end, opposition side is called upper end.
As shown in Figure 3, clasp 20 is formed as cylindric, and has the internal duct 23 be communicated with disposal appliance passage 16 (with reference to Fig. 1).As shown in Figures 4 and 5, internal duct 23 is formed as the taper that internal diameter diminishes gradually from upside towards downside.As shown in Figure 6, on the outer peripheral face of clasp 20, be formed with external thread part 20a in bottom, be formed with filler mounting groove 20b at central part, be formed with flange 25 on top.External thread part 20a and the internal thread part (not shown) be formed in access portal portion 17 screw togather, thus clasp 20 is fixed on access portal portion 17.Filler (not shown) is accommodated with at filler mounting groove 20b.Filler prevents the leakage from the gap with access portal portion 17 of body fluid, dirt, air etc.
Flange 25 circle less of the middle body of clasp 20.Key 21 is locked to this flange 25, and key 21 dismounting is installed on clasp 20 freely.On flange 25, carry out otch by corner part formed by upper surface and outer peripheral face, and form inclined plane (hereinafter referred to as flange slope face) 25a.
Key 21 prevents adverse current and the situation of externally leaking from clasp 20 in disposal appliance passage 16 such as body fluid in body when being disposed by disposal appliance 14.The spool 31 that key 21 has framework 30, kept by this framework 30.Spool 31 is inaccessible by clasp 20, and allows the insertion of this disposal appliance 14 when inserting disposal appliance 14 (with reference to Fig. 1).
As shown in Figure 7, the linking belt (linking part) 34 that spool 31 has cap 32, valve portion 33 and they linked, is made up of elastomers such as rubber.Cap 32 possesses valve film 36, and entirety is formed as lid, and this valve film 36 has breach 35.Annular protrusions 37 outstanding is to the inside formed at the inner peripheral surface of this cap 32.And, the dismounting handle part 38 of the cross sectional shape identical with linking belt 34 is linked with in the opposition side of the link side linked with linking belt 34 of cap 32.Be formed with two extensions and refer to use projection 38a the upper surface of this dismounting handle part 38 is outstanding.
Valve portion 33 possesses valve film 42, is formed as tubular, and this valve film 42 has disposal appliance through hole 41.Valve film 42 is in hemispherical or conical surface-shaped ground depression, and heart portion has disposal appliance through hole 41 wherein.Valve portion 33 is inserted in frame main body 45, is kept by inner peripheral surface 45a.
As can be seen from figures 8 and 9, framework 30 have roughly cylindric frame main body 45, the fixed claw 46 being formed at this frame main body 45, engagement pawl 47,48, separation handle part 52, insertion opening 54, lateral opening 55, flange 56, integrally formed by plastics.Inner peripheral surface 45a is to the underpart opening of frame body 45.Fixed claw 46 and engagement pawl 47,48 is formed in the bottom of this inner peripheral surface 45a.And, locking stage portion 45d is formed in the upper end of inner peripheral surface 45a.On the outer peripheral face of frame main body 45, form separation handle part 52, two openings 54,55 successively from lower end.On the upper surface of frame main body 45, be formed with the flange 56 for installing valve portion 33.
Flange 56, in the same manner as the flange 25 of clasp 20, has flange outer sides inclined plane 56a in outer peripheral face side.And, in inner peripheral surface side, there is flange inner inclined plane 56b.As shown in Figures 4 and 5, when covering cap 32 to flange 56, the annular protrusions 37 of cap 32 expands distortion in the mode of crossing flange outer sides inclined plane 56a, outer peripheral face 56c (with reference to Fig. 8), and the locking surface 37a of annular protrusions 37 is locked to the locking surface 56d of flange 56.Thus, cap 32 can not come off simply from the upper end of frame main body 45.
As shown in Figure 10, two openings 54,55, at the central part of frame main body 45, circumferentially separate the interval configuration of roughly 180 degree.As shown in Figure 6, the state that valve portion 33 is out of shape to be crushed is inserted from the insertion opening 54 of a side.After such insertion, as shown in Figures 4 and 5, when valve portion 33 recovers by the elastic force of self, outer peripheral face 33a and the inner peripheral surface 45a in valve portion 33 touch.As shown in Figure 6, the lateral opening 55 of the opposing party has connection opening 55a in bottom, compared with insertion opening 54, is formed significantly downward.Connection opening 55a arrives the frangible portion 71 illustrated below.
As can be seen from figures 8 and 9, the continuous portion 57 between insertion opening 54 and the lateral opening 55 and spacing that inner peripheral surface 45a thereunder circumferentially spends with roughly 180 is formed with two fixed claws 46.As shown in Figure 5, described fixed claw 46, when frame main body 45 is assemblied in clasp 20, crosses the flange 25 of clasp 20.Thus, the locking surface 46a of fixed claw 46 is locked to flange locking surface 25b.And on inner peripheral surface 45a, as can be seen from figures 8 and 9, the engagement pawl 47,48 that flange slope face 25a abuts is outstanding towards inner side.Engagement pawl 47,48 circumferentially stagger relative to fixed claw 46 90 degree position and formed on the position of amount of thickness being separated flange 25 relative to fixed claw 46 upward.It should be noted that, the engagement pawl 47 of a side is divided into two by connection opening 55a.By described fixed claw 46 and engagement pawl 47,48, form and make key 21 be locked to the fastener in access portal portion 17.
As shown in Figure 9, between the inner peripheral surface 45a of frame main body 45 and lower surface 45b, carried out chamfer machining, become the insertion guide surface 63 of taper.By this insertion guide surface 63, guide when the flange 25 of clasp 20 inserts.
As shown in Figure 8, the bottom of the outer peripheral face 45c of frame main body 45 corresponds to inserts guide surface 63, becomes the conical surface 64 along with expanding gradually towards lower end.By this conical surface 64, guarantee the wall thickness of the bottom of frame main body 45, the intensity of the bottom of holding frame main body 45.
The conical surface 64 is formed to the outstanding separation handle part 52 of the radial direction of frame main body 45.As shown in Figure 9, separation with handle part 52 relative to the circumferencial direction central link by two fixed claws 46, by the straight line L1 of the cylinder heart CL1 of frame main body 45, outstanding to roughly orthogonal radial direction (being represented by straight line L2).When considering centered by separation handle part 52, relative to the centre line L 2 of the radial direction by cylinder heart CL1 of separation handle part 52, at line symmetry and by the position of cylinder heart CL1 forms two fixed claws 46.This separation handle part 52, in the horizontal plane comprising two fixed claws 46, is formed as having the U-shaped expanding and allow opening 65.
As shown in Figure 8, close to the both sides to the bonding part that frame main body 45 engages and separation handle part 52 of separation handle part 52 and the outer peripheral face 45c be positioned at than frame main body 45 by the part outside radial direction, to be formed with the cylinder heart CL1 of frame main body 45 otch (recess) 70 upward from lower end abreast.Due to the existence of this otch 70, on the cylinder heart direction of frame main body 45, separation handle part 52 is formed as with the linking portion of frame main body 45 amount shortening otch 70.This linking portion being formed shorter becomes the frangible portion 71 for making separation handle part 52 be separated from frame main body 45.
Otch 70 is formed with constant width.As shown in Figure 10, a pair opposed cut sides 70a plays function as stopper, and when separation handle part 52 is pressed downward, restriction cut sides 70a each other comes in contact and produces further bending.As shown in figure 11, otherwise when separation handle part 52 is pressed upward, the contact produced owing to not having cut sides 70a, therefore, it is possible to make separation handle part 52 bend significantly upward.Due to this flexural deformation, frangible portion 71 reaches fracture after there occurs plastic deformation.Like this, by the square one-tenth otch 70 in cylinder heart direction, can by the bendable angle θ 1 of the separation handle part 52 divided by otch 70, θ 2 below and above be set as different angles.Further, in the flexural deformation employing large bendable angle θ 2, frangible portion 71 reaches fracture, in the flexural deformation employing little bendable angle θ 1, becomes in regime of elastic deformation.It should be noted that, the situation of side otch 70 being formed at a heart direction can be replaced and be formed at two sides.In this case, by changing two incision lengths, the bendable angle θ 1 above and below can making, θ 2 have difference.
As shown in Figure 6, when assembling spool 31 to framework 30, making it distortion owing to being flattened in valve portion 33, being therefore inserted in frame main body 45 from insertion opening 54.Because valve portion 33 is formed as tubular, therefore easily carry out flattening such distortion.When valve portion 33 recovers in frame main body 45, the outer peripheral face 33a in valve the portion 33 and inner peripheral surface 45a of frame main body 45 touches, and in the pulling in common opereating specification etc., can not come off from insertion opening 54.
In addition, the inner peripheral surface 45a of frame the main body 45 and outer peripheral face 33a in valve portion 33 touches, and the locking stage portion 45d of the inner circumferential of frame main body 45 (with reference to Fig. 9) touches with the upper end 33b in valve portion 33, thus, even if form connection opening 55a or opening 54,55 in frame main body 45, body fluid etc. also can not from described opening 54,55,55a leaks.Especially setting the height in valve portion 33 in the mode of bearing compression by the flange 25 of clasp 20 being inserted into valve portion 33 in frame main body 45, therefore can guarantee the adhesion of the inner peripheral surface 45a of frame main body 45 and the upper end 33b in valve portion 33.And also guarantee the adhesion in clasp 20 and valve portion 33, airtight of water tightness is between the two guaranteed.
As shown in Figure 1, in use, key 21 is assemblied in the access portal portion 17 of the operating portion 12 of endoscope 10.The bottom of key 21 as shown in Figure 3, is pressed into the flange 25 of outer mode to clasp 20 by this assembling.Thus, as shown in Figure 9, with expanding of separation handle part 52, the bottom of frame main body 45 allows that the mode that opening 65 is opened is out of shape, therefore two fixed claws 46 of inner peripheral surface 45a move along arrow A 1 direction, can easily cross flange 25.When flange 25 crossed by fixed claw 46, fixed claw 46 abuts with locking surface 46a, 25b of flange 25 and reliably engages, and therefore, frame main body 45 can not be pulled up from clasp 20 in this condition afterwards.
Embed to the flange 56 of frame main body 45 at cap 32 and do not use disposal appliance 14 state under, the breach 35 of cap 32 by cap 32 elastic force and touch, keep airtight of water tightness state.
When using the disposal appliance 14 of the comparison path in disposal appliance 14, under the state making cap 32 embed the top of frame main body 45, disposal appliance 14 can be inserted from the breach 35 of cap 32.When making disposal appliance 14 through breach 35, under the elastic force of cap 32, cut sides becomes the state of touching with the outer peripheral face of disposal appliance 14.Therefore, even if be inserted in the body of patient by insertion section 11, blood or body fluid etc. also can not from keys 21 to external leakage.And, when diameter large disposal appliance 14, cap 32 can be dismantled from frame main body 45, and insert disposal appliance 14 from the disposal appliance in valve portion 33 through hole 41.
After the use of endoscope 10, key 21 is dismantled from clasp 20 and carries out the cleaning of endoscope 10.When key 21 is dismantled from clasp 20, as shown in figure 11, grip separation handle part 52 and mention upward, thus centered by frangible portion 71 by separation handle part 52 bending upward.When bending angle exceedes bendable angle θ 2, there is plastic deformation in frangible portion 71, then ruptures.
After fracture, separation handle part 52 is separated from frame main body 45, and the lateral opening 55 therefore with connection opening 55a opens wide and becomes the state that downward end opens significantly.Thus, fixed claw 46 can remove locking simply with the flange 25 of clasp 20, can easily dismantle key 21 from clasp 20.And make separation handle part 52 from the state that frame main body 45 is separated, connection opening 55a and lateral opening 55 become opening-wide state.Therefore, the assembling to clasp 20 again cannot be carried out, even if assembling also can dismantle key 21 simply, therefore can prevent from re-using.
According to the present embodiment, as shown in Figure 6, there is the spool 31 of elasticity system, and this spool 31 have cap 32, valve portion 33, linking belt (linking part) 34, therefore without the need to their splits being formed, can reduce components number.And, due to the minimizing of components number, and assemble and also reduce man-hour.
In addition, due to have be formed in frame main body 45 side on and make valve portion 33 be out of shape insert insertion opening 54, by valve portion 33 is locked to insertion opening 54, and frame main body 45 is accommodated in valve portion 33, different from the situation that valve portion 33 is inserted in such cylinder heart direction from frame main body 45 in the past, there is no need for making them be locked to the locking projection etc. of inner peripheral surface 45a.Therefore, correspondingly the structure of the inner peripheral surface 45a of frame main body 45 becomes simple, and the root portion of cutting reduces, and therefore Making mold becomes simple, and the shaping adaptability of framework 30 improves.
By frame main body 45 is set to plastics system, and the spool of elasticity system is directly embedded compared with clasp 20, clasp 20 can be installed on securely thus.Therefore, when extracting disposal appliance, frame main body 45 can not come off from clasp etc.
Cap 32 possesses valve film 36 and this valve film 36 has breach 35, and thus, cap 32, except lid function, can also make the thin disposal appliance of diameter pass.Therefore, even if thin the first disposal appliance of diameter is passed, the leakage of body fluid etc. can also reliably be prevented.And, valve portion 33 possesses valve film 42 and is formed as tubular, and this valve film 42 has the inserting hole 41 of second disposal appliance larger than the diameter of above-mentioned first disposal appliance, thus, for first and second disposal appliance that diameter is different, the leakage of body fluid etc. reliably can be prevented.
By valve portion 33 is configured to tubular, and be easily out of shape.Thus, as shown in Figure 6, valve portion 33 can easily be inserted from insertion opening 54 in frame main body 45.And, as shown in Figure 5, frame main body 45 is made to embed the flange 25 of clasp 20, fixed claw 46 is made to be locked to the locking surface 25b of flange 25, in this condition, valve portion 33 is made to carry out compression along cylinder heart direction in frame main body 45, thus, the diameter in valve portion 33 increases, and the outer peripheral face 33a in valve the portion 33 and inner peripheral surface 45a of frame main body 45 touches.Therefore, even if form insertion opening 54, lateral opening 55 on the outer peripheral face of frame main body 45, valve portion 33 and frame main body 45 also maintain tightlock status, and therefore body fluid etc. can not leak from insertion opening 54, lateral opening 55.
As shown in Figure 9, in the both sides of separation with handle part 52, cylinder heart direction along frame main body 45 forms otch 70, due to the existence of this otch 70, on the cylinder heart direction of frame main body 45, be provided with the frangible portion 71 that separation handle part 52 shortens with the linking portion of frame main body 45, thus, separation handle part 52 can be made simply to be separated from frame main body 45, easily can to carry out the dismounting of key 21.
As shown in Figure 8, the lateral opening 55 with connection opening 55a is formed above separation handle part 52 and in frame main body 45, thus, when separation handle part 52 is separated from frame main body 45, connection opening 55a and lateral opening 55 become the state of opening wide from bottom, form the large opening comprising lateral opening 55 in the lower end of frame main body 45.Thus, make the shape of the frame main body 45 after handle part 52 separation that larger change occurs.Therefore, the dismounting from access portal portion 17 of key 21 can be carried out simply.Especially by cylinder heart direction central part lateral opening 55 being formed to frame main body 45, when frangible portion 71 being ruptured when being pressed from lower end side to upper end side by separation handle part 52, due to cutting off of separation handle part 52 frame main body 45 from the side opening 55 open significantly, can more simply by use after framework 30 dismantle from clasp 20.And, by the adjustment separation length of handle part 52 with the linking portion of frame main body 45, the setting of the fracture strength of frangible portion 71 easily can be carried out.
As shown in Figure 9, by being formed, there is the separation handle part 52 expanding the roughly U-shaped of allowing opening 65, if insert key 21 to access portal portion 17, then when the distortion when flange 25 crossed by the fixed claw 46 of inside, expanding of the separation handle part 52 of roughly U-shaped can be made to allow that opening 65 is out of shape.Thus, the stress that distortion produces can not be concentrated and act on frangible portion 71, when the insertion of key 21, can not be destroyed by key 21 by mistake.
On position outside the radial direction relative to frame main body 45, otch 70 is formed from the lower end of frame main body 45 towards upper end, thus as shown in Figure 10, in the pressing operation of separation from the upper end toward the lower end with handle part 52, the relative face 70a of otch 70 contacts with each other and becomes the stopper of pressing operation.Therefore, the distortion of fracture can not be reached, separation handle part 52 can not be made by mistake to be separated from frame main body 45.
Separation handle part 52 is formed in than fixed claw 46 side on the lower, lateral opening 55 its with to be separated with handle part 52 between there is connection opening 55a, connection opening 55a is formed to frangible portion 71, thus, when making separation handle part 52 be separated from frame main body 45, can make frame main body 45 that larger change of shape occurs by lateral opening 55 and connection opening 55a, thus easily carry out the dismounting of key 21, and can prevent from re-using.
As shown in Figure 9, lateral opening 55 is formed in the position being circumferentially separated 180 degree relative to insertion opening 54, thus, frame main body 45 is separated by two openings 54, about 55, compared with one-piece type cylinder, the part forming fixed claw 46 becomes short cylinder body shape.Therefore, compared with one-piece type cylinder, flexural rigidity declines, easily to arrow A 1 Direction distortion of opening and closing fixed claw 46.Thus, the opening and closing of the fixed claw 46 when frame main body 45 being assembled to clasp 20 or when dismantling becomes easy, assembling when can use simply or the dismounting after using.
(the second embodiment)
As shown in Figure 12 ~ Figure 16, in the framework 79 of the 5th embodiment, be separated from frame main body 94 in order to avoid the separation handle part 93 that there occurs separation because of frangible portion 92 and separate, frangible portion 92 being only set in a side side of separation handle part 93, and elasticity linking part 95 is set the opposing party.Due to the existence of otch 96, the wall thickness in cylinder heart direction reduces frangible portion 92.
Elasticity linking part 95 is extended along the circumferencial direction of frame main body 94 from the side of separation handle part 93, and its front end bends to roughly 90 degree and links with frame main body 94.Formed to expand at separation handle part 93 and allow opening 97.This expands allows the inner peripheral surface opening of opening 97 to frame main body 94, forms the parting portion 64a of the conical surface 64.And, as shown in figure 13, be circumferentially separated on the position of 180 degree relative to parting portion 64a, forming parting portion 64b by the opening of the circumferentially parting conical surface 64.By described parting portion 64a, 64b, expand and allow opening 97 and elasticity linking part 95, when frame main body 94 being assembled to clasp 20 (with reference to Figure 15), as shown in the arrow A 1 of Figure 14, a pair fixed claw 46 easily expands to the direction of opening.Therefore, fixed claw 46 crosses the flange 25 (with reference to Fig. 3) of clasp 20 and the assembling to clasp of key becomes easy.
Elasticity linking part 95 becomes the thickness of below the half of the thickness of separation handle part 93, is not formed at the otch 96 of frangible portion 92.Elasticity linking part 95 as shown in figure 12, is La in length, and width is Wa, when thickness is ta, is preferably ta≤Wa, La >=2 × ta.Like this, by forming elasticity linking part 95, when rupturing from frangible portion 92 separation handle part 93 is pressed upward, the bending resistance that the elastic force that can reduce elasticity linking part 95 produces.
In this second embodiment, if separation handle part 93 is pressed upward and because of frangible portion 92 bend time, bending stress concentrates on frangible portion 92, after frangible portion 92 there occurs plastic deformation, reach fracture.Elasticity linking part 95 is the thickness of below the half of separation handle part 93, even if apply to reach the such flexural deformation of fracture because of frangible portion 92, also terminates in regime of elastic deformation, can not rupture.Therefore, as shown in figure 16, the separation handle part 93 ruptured from frangible portion 92 becomes by elasticity linking part 95 state linked with frame main body 94, therefore, it is possible to reliably discard together with frame main body 94.Therefore, separation handle part 93 can not be there is be separated from frame main body 94 and become the situation of split with frame main body 94 as in the past, and can not forget etc. due to the separation handle part 93 after being polluted by body fluid etc. discarded and the risk that infects occur.
