Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, but embodiment of the present utility model does not limits
In this.
This utility model is membrane lung connection fixture in extracorporeal circulation, and this fixture can make the installation of membrane lung with dismounting very
Efficient and convenient, it is greatly saved operating time.This fixture is made up of two parts, and a part is secured on extracorporeal circulation bracing frame
Fixing clamp-seat 1, another part is attached to the membrane lung adpting flange 2 on membrane lung 3, and outline drawing is as it is shown in figure 1, for the ease of saying
Bright add a kind of possible membrane lung 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, the upper end cover being arranged in order
12, lifting dish 14 and bottom end cover 16；Lifting post 13 is through upper end cover 12 center, and one end is connected with lifting-pulling cap 11, separately by screw thread
One end fastens with lifting dish 14 through lifting dish 14 centrally through nut, and 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, and bottom end cover passes through flange 161 and upper end cover
12 connect, and offer four bigger holes of ratio vertical card column diameter at four vertical card column 15 correspondence positions, when lifting-pulling cap 11 to
During upper lifting, vertical card column 15 can move up and down in hole, makes vertical card column expose or is 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.Film
Lung adpting flange is an one-piece parts, uses plastic material to be molded.The structure of membrane lung adpting flange as shown in Figure 4, its
For the cylindrical barrel 21 with a bottom surface 22, bottom surface 22 is offered the fixing hole 24 for being connected with membrane lung, can be by being somebody's turn to do
Membrane lung adpting flange 2 is fixed on membrane lung 3 by fixing hole 24, and cylindrical barrel 21 internal face is evenly equipped with four adapters, even
Connecing device to be mainly made up of a claw 23, 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, and upper surface is inclined-plane, at the bottom of the lower surface of this claw and circular cylinder body
Form horizontal card column groove 231 between face, formed between side (this side of high-end correspondence on inclined-plane) and the cylinder lateral wall of this claw
Vertical card column groove 232.
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, make horizontal card column wrong with the claw of membrane lung adpting flange
Open, 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 ejecting under the effect on inclined-plane, 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, falls into downwards in vertical card column groove, so that membrane lung adpting flange cannot be to the left
Rotating, 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 level
During card column groove, membrane lung can be unloaded.
