The 11st figure is similar to the 2nd figure, is the perspective diagram of the 4th embodiment of foundation distributor of the present invention.
Be first the present preferred embodiment according to distributor of the present invention shown in the 1st and 2 figure, its integral body is with reference number 10 representatives.This distributor comprises a case, include the casing component 12 of a groove shape, as taking up and support two fluids that are equipped with separately, it is the syringe 80 and 81 of the plain former and hemopexin of fibrin, this fluid will accurately be distributed from syringe with specific quantity by syringe, and will be mixed each other to produce the mixture that can form so-called tissue glue.The case of distributor 10 further comprises a lid 22, and it is received this groove shape casing component 12 along a sheet metal hinge 23.This groove shape casing component 12 also has a rear wall 16, and is provided with semi-circular cut-out with as a partition wall 18 of accepting syringe 80 and 81 outer surface effects and an antetheca 20.Lid 23 only covers the some of groove shape casing component 12, and reserves the major part of syringe 80 and 81, checks in order to operating personnel.
This groove shape casing component 12 is integrally received leader 50, and groove shape casing component 12, lid 22 and handle 50 all form with the system of moulding as the impact resistance plastics of polystyrene and so on.This handle 50 is limited with a hole 52 or an inner room, has wherein taken up a plate machine 60, and this plate machine is setovered towards the resting position shown in the 1st figure by one section spring element 66 that is made of the Elastic plastic-rubber pipe.The inner room of handle 50 has an opening towards the case of distributor 10 and passes a hole 58 of groove shape casing component 12.Plate machine 60 utilizes some pins to be maintained at can be with respect to the position of these handle 50 rotations, one of them pin is shown among the 2nd figure and with reference number 64 and represents, it is stretched out by the outer surface of plate machine 60, these locks are supported in respectively in the hole of handle 50, and one of them hole is shown among the 2nd figure and with reference number 54 and represents.Understand easily, plate machine 60 can rotate around a rotating shaft with respect to handle 50, and this axle is coaxially to pass pin 64 and hole 54.When plate machine 60 rotated with respect to its rotating shaft, an idle running element 62 of this plate machine 60 also was rotated with respect to same axis.
The plate machine is sent to tooth bar 42 with the further rotation of idle running element 62, and tooth bar 42 is taken up in groove shape casing component 12 and stays in and take up on the projection position 34 and 36 on the tooth bar 42.This tooth bar is by projection parts 34 and 36 guiding, so that can allow tooth bar 42 with respect to 12 displacements of groove shape casing component.This displacement is to be positioned from this tooth bar 42 to be adjacent to the punctured position of these groove shape casing component 12 rear walls 16, moves on to the pull-out location that this tooth bar 42 is moved toward groove shape casing component partition wall 18.
Therefore, tooth bar 42 can be in groove shape casing component 12, between its punctured position and pull-out location, carries out reciprocal displacement by projection parts 34 and 36 guiding.The reciprocating action of tooth bar 42 produces when plate machine 60 is manually operated, and when the downward projection position 44 of the idle running element 62 of plate machine 60 and tooth bar 42 and 46 interoperations, the position of this downward projection can straddle on idle running element 62.Tooth bar 42 surface thereon is provided with tooth, and as the purpose that promotes propeller body 70, this will be described in a more detailed discussion hereinafter.
The 2nd figure has also disclosed syringe 80 and 81 in more detail, and they are originally as general habitual structure.Syringe 80 and 81 comprises a syringe cylinder 82 and 83 respectively, an end of this syringe cylinder be opening to take up the fitting piston bar, then be respectively equipped with dispense tip 84 and 85 at the opposite other end.Syringe cylinder 82 and 83 is provided with the flange 86 and 87 of projection at its end.At syringe cylinder 82 and 83 piston rod 88 and 89 places are housed respectively, this piston rod 88 and 89 is limited with external 90 and 91 and piston body 92 and 93 respectively, and these piston bodies are respectively to be airtight relation with syringe cylinder inner circular tubular surface and to match.
This syringe 80 and 81 takes up in the groove shape casing component 12 of distributor 10 as described above, and is supported by the partition wall 18 of this groove shape casing component 12 and the antetheca 28 of lid 22.Syringe 80 and 81 is further supported by the antetheca 20 of groove shape casing component 12, and is fastened in the location by the inner width of groove shape casing component 12 and lid 22.Therefore, the flange 86 of syringe cylinder 82 is supported in the inner width 32 of lid 22 and is located in the inner width 39 in groove shape casing component 12 interior 38 the place aheads, projection position that make progress.Similarly, the flange 87 of the syringe cylinder 83 of syringe 81 is located in the groove shape casing component 12 and by the inner width 41 that its wall 40 limited and is fastened.
As mentioned above, the shift reciprocately of tooth bar 42 or action are sent to propeller body 70, with from this syringe 80 and 81 distributing fluids.This propeller body 70 can obviously be found out in the 2nd figure, limits an end face 72 and an inner width 74, with respectively with 90 and 91 operations of syringe 80 and 81.Propeller body 70 also is provided with oppositely the projection position 76 and 77 of configuration, to match with the tooth of tooth bar 42 and the tooth 30 of being located at lid 22 internal layer surfaces respectively.
When lid 22 was closed, the teeth 30 on the inner surface of lid 22 formed upwards projection position 77 engagements with this propeller body 70, and its downward projection position 76 also with tooth 48 engagements of tooth bar 42.When plate machine 60 is manually actuated the rotating shaft that causes idle running element 62 to be limited with respect to pin 64 and rotates, tooth bar 42 from the punctured position displacement of its abuts rear wall 16 towards its pull-out location in abutting connection with partition wall 18.When tooth bar 42 as above-mentionedly when its punctured position is moved into its pull-out location, propeller body 70 also is shifted towards partition wall 18 and antetheca 28, causes piston rod 88 and 89 respectively with respect to the syringe cylinder 82 and 83 displacements of syringe 80 separately and 81.And then cause fluid to distribute by syringe 80 and 81.When plate machine 60 was allowed to return back to its resting position by the biasing of replying element 66, tooth bar 42 was also returned back to its initial or punctured position.But, the tooth 30 of lid 22 can prevent that but propeller body 70 from returning back to its original position, and thereby prevent the bidirectional-movement of propeller body 70, so this propeller body 70 is to be allowed to and can only to move with the case of single direction with respect to this distributor 10.
Be appreciated that, the tooth 30 on lid 22 inner surfaces is can prevent the mode of propeller body 70 with respect to the groove shape casing component 12 reverse displacements of distributor 10, and match with the projection position 77 of propeller body 70, and the tooth 48 of tooth bar 42 is that mode with similar ratchet matches with the projection position 76 of propeller body 70.To recognize further that also tooth 30 also can replace with the friction surface position of lid 22 for example in some instances, and perhaps itself can provide suitable friction when preventing any reverse displacement of this propeller body 70 at lid 22, even can be with tooth 30 omissions.
So can know to have only when lid 22 is closed in the closed position shown in the 1st figure, just can produce and make the back and forth manual activation of the plate machine 60 of displacement of tooth bar 22; Otherwise when this tooth bar only slides along the projection position 76 of these propeller body 70 below side surface, but not advance propeller body 70 when partition wall 18, can't cause propeller body 70 to move towards partition wall 18 from the original position that it is adjacent to rear wall 16.
Above-mentioned propeller body 70 is provided with a single inner width 74, to take up 91 of syringe 81.Selectively or add ground, this propeller body 70 can be provided with a similar inner width to take up 90 of this syringe 80.If this propeller body 70 is provided with two place's inner widths as inner width 74, then two inner widths preferably are configured to be taken up two syringe nozzles that cooperated by the two opposite sides of propeller body, and allow that employing especially simply and the mounting means of using easily.As obviously finding out,, be exactly always the composition of distributor 10 has 5 elements in the 2nd figure: the first, plate machine 60; The second, spring element 66; The 3rd, integral body contains the casing component of jug 50, groove shape casing component 12 and lid 22; The 4th, tooth bar 42; With the 5th, propeller body 70.
Above-mentioned first present preferred embodiment 10 according to the distributor that the present invention implemented be used to branch be fitted to syringe 80 81 in the fluid of special predetermined quantity, this quantity is that 16 punctured position is determined by the stroke distances of propeller body 70 towards the process that partition wall 18 and antetheca 28 move from it in connection with rear wall in distributor 10 cases at propeller body 70.Therefore, amount of fluid that distributes from syringe 80 and 81 and propeller body 70 are with respect to the location independent of distributor case, but with the proportional relation of the stroke distances of propeller body 70, so from syringe 80 and 81 amount of fluid of being distributed can constitute one fixedly than, this promptly limits the special constant ratio of the mixing ratio of these two kinds of fluids.
In some instances, must change the mixing ratio of these two kinds of fluids, even need only distribute wherein a kind of fluid.Show one according to the embodiment that the present invention implemented in the 3rd and 4 figure, distributor wherein is through revising a little, and with its integral body of reference number 10 ' represent.
Above-mentioned projection position 76 and 77 oppositely is located in first embodiment of distributor each other, is sandwiched in the inner room that is limited in the groove shape casing component 12 when lid 22 is closed to prevent propeller body 70.In addition, the projection position 76 and 77 of the foregoing description is positioned at propeller body 70 foremost, yet selectively is positioned at the middle position and the rear position of propeller body 70 with the projection position 76 and 77 that the tooth 30 of the tooth 48 of tooth bar 42 and lid 22 cooperates respectively.And, one group of above projection position and low-friction surface element can be provided in for example downside surface of propeller body 70, so that when its punctured position is returned to initial pull-out location, help propeller body 70 to move along the tooth 48 of tooth bar 42 at tooth bar 42.
The 3rd with the distributor 10 shown in 4 figure ' different be basic with the distributor 10 shown in the 1st and 2 figure, propeller body 70 wherein and tooth bar 42 are replaced to respectively propeller body that separates that cooperates with a syringe and the tooth bar that separates.Therefore, tooth bar 42 shown in the 2nd figure the 3rd and 4 figure just replace discrete tooth bar 42 ' and 42 "; and be equipped with respectively the discrete propeller body 70 shown in the 4th figure ' and 70 ", further be equipped with again and syringe-like 80 shown in the 1st and 2 figure and 81 syringe separately, but in the 3rd and 4 figure, omitted for brevity.Along with discrete tooth bar 42 ' and 42 " provide; the tooth 30 of the lid 22 shown in the 2nd figure is replaced the tooth 33 and 31 of separation; when being closed into the closed position of lid 22 positions among similar as the 1st figure at lid 22, with propeller body 70 ' with 70 " matches or meshes.Tooth bar 42 ' and 42 " similar above-mentioned tooth bar 42 elements of the element that comprises, these elements when the reference number that contrasts in this tooth bar 42 elements, respectively with ' and " represent.Therefore, this tooth bar 42 ' and 42 " comprise respectively this projection position 44 ' and 44 ", projection position 46 ' and 46 " and tooth 48 ' and 48 ".
Distributor 10 ' handle 50 be furnished with a plate machine 60 of revising a little ', it and above-mentioned plate machine 60 differences be plate machine 60 ' a be provided with hole 67 ', a sliding pin 68 projections wherein arranged and pass.Pin 64 of this plate machine 60 ' utilize with above-mentioned reference the 2nd figure have same purpose run through axle 64 ', and with respect to these handle 50 motions, this still has another purpose to be connected to the lever 69 that sliding pin 68 constitutes L shaped element for supporting an integral body.Plate machine 60 ' a be provided with idle pins 62 ' integral body be connected to plate machine 60 ', idle pins 62 ' identical with idle running element 62 effects of above-mentioned plate machine 60.This idle running element 62 ' in the 3rd figure, can obviously find out be with tooth bar 42 ' downward projection position 44 ' and 46 ' cooperate.This lever is provided with an idle pins 62 at its end in contrast to sliding pin 68 ", " match with tooth bar 42 " downward projection position 44 " and 46.
If the syringe that will be similar to syringe 80 shown in above-mentioned the 2nd figure and 81 be positioned distributor 10 ' groove shape casing component 12 in, and if propeller body 70 ' and 70 " be positioned head respectively; promptly shown in the 2nd figure separately 90 and 91 of syringe 80 and 81 piston rod 88 and 89 in connection with syringe; and if lid 22 the close position class position of lid 22 shown in the 1st figure seemingly, distributor 10 ' just can use then for being ready for.
