Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, but embodiments of the present invention are not limited to this.
The present invention is membrane lung connection fixture in extracorporeal circulation, and this fixture can make the installation of membrane lung the most efficient and convenient with dismounting, is greatly saved operating time.This fixture is made up of two parts, a part is secured to the Fixing clamp-seat 1 on extracorporeal circulation bracing frame, and another part is attached to the membrane lung adpting flange 2 on membrane lung 3, and outline drawing is as shown in Figure 1, add a kind of possible membrane lung the most in FIG, subsequent figure will be omitted membrane lung.
The particular make-up structure of this fixture is as in figure 2 it is shown, Fixing clamp-seat includes lifting-pulling cap 11, upper end cover 12, lifting dish 14 and the bottom end cover 16 being arranged in order；Lifting post 13 is through upper end cover 12 center, one end is connected with lifting-pulling cap 11 by screw thread, the other end fastens with lifting dish 14 through lifting dish 14 centrally through nut, lifting dish 14 is uniformly distributed on peripheries with four vertical card columns 15, described bottom end cover 16 includes flange 161 and the cylinder 162 being fixed together, bottom end cover is connected with upper end cover 12 by flange 161, and offer four bigger holes of ratio vertical card column diameter at four vertical card column 15 correspondence positions, when lifting-pulling cap 11 upwards lifts, vertical card column 15 can move up and down in hole, make vertical card column expose or be contracted in end cap, as shown in Figure 3.The cylinder 162 of bottom end cover is used for being connected with membrane lung adpting flange 2, uniform four horizontal card columns 17 on cylinder 162 side.Membrane lung adpting flange is an one-piece parts, uses plastic material to be molded.The structure of membrane lung adpting flange is as shown in Figure 4, it is the cylindrical barrel 21 with a bottom surface 22, the fixing hole 24 for being connected is offered with membrane lung on bottom surface 22, by this fixing hole 24, membrane lung adpting flange 2 can be fixed on membrane lung 3, four adapters it are evenly equipped with on cylindrical barrel 21 internal face, adapter is mainly made up of a claw 23, and each claw matches with cylinder the horizontal card column groove of formation respectively 231 and vertical card column groove 232.
Described claw 23 has upper surface and lower surface, upper surface is inclined-plane, form horizontal card column groove 231 between lower surface and the circular cylinder body bottom surface of this claw, the side (this side of high-end correspondence on inclined-plane) of this claw with form vertical card column groove 232 between cylinder lateral wall.
The concrete connection procedure of this fixture is as it is shown in figure 5, the most for convenience of description, it is shown that partial sectional face view:
First by the face of cylinder of membrane lung adpting flange alignment bottom end cover, horizontal card column is made to stagger with the claw of membrane lung adpting flange, then by pushing away on membrane lung adpting flange and bottom end cover cylindrical surface adhesive, as shown in Fig. 5 (a).
Then by membrane lung adpting flange to right rotation, in rotary course, vertical card column touches inclined-plane, claw upper end, and upwards ejects under the effect on inclined-plane, and horizontal card column enters in the horizontal card column groove of membrane lung adpting flange, as shown in Fig. 5 (b).
Finally when block face on the left of horizontal card column encounters horizontal card column groove, membrane lung adpting flange cannot continue to right rotation, now vertical card column crosses inclined-plane, claw upper end, fall into downwards in vertical card column groove, so that membrane lung adpting flange cannot be to anticlockwise, so far membrane lung adpting flange can be stably connected with on Fixing clamp-seat, such as Fig. 5 (c).
When needs dismounting membrane lung, lifting-pulling cap is mentioned, to anticlockwise membrane lung adpting flange, when horizontal card column departs from horizontal card column groove, membrane lung can be unloaded.
