The specific embodiment
Embodiment of the present utility model is described now.With reference to figure 1, according to an embodiment of the present utility model, disposable pulse pipe 3 (disposable pulsatile tube) comprises body 31; The cardiopulmonary bypass machine end (CPB end) 34 that is formed at an end of described body 31 and is used for connecting with a cardiopulmonary bypass machine (CPB machine, cardiopulmonary bypass machine is with reference to figure 4) 50; Be formed at the other end of described body 31 and be used to embed the intravital patient of patient end (patient end) 32; And be formed at two inner cavity (double lumen portion) 36 between described cardiopulmonary bypass machine end 34 and the patient end 32.
The described pair of inner cavity 36 can connect with the outer counter pump (external contra pulsation pump is with reference to figure 4) 60 of fighting by being arranged on the passages 38 in the described body 31.Described outer counter fight pump 60 provide regularly suitable gas such as helium or carbon dioxide so that make described pair of inner cavity 36 be inflated or exit, thereby be formed with the pulse flow that rule drives blood samples of patients.In this case, for making described pair of inner cavity 36 more freely be inflated or exitting, described pair of inner cavity 36 preferably includes integrally formed intra-arterial air bag barrier film (intra aortic balloon membrane).And described integrally formed intra-arterial air bag barrier film is preferably the inner chamber body (intra luminal) that patient's blood flow is directly exerted pressure.In addition, the length of described pair of inner cavity 36 can be 45cm.Described pulse pipe 3 can be for 1.2-1.6 rice long and its diameter be 11-13mm.The described integrally formed membranous volume of intra-arterial air bag can be 10-110 machine pulse/minute (machinepulse/min) for 40cm3 and its pulse frequency.
Fig. 3 is the three-dimensional exploded view of described pulse pipe of embodiment of this utility model and intra-arterial balloon catheter (intra aortic balloon catheter, IAB catheter).Fig. 4 is the axonometric chart after pulse pipe shown in Figure 3 and the assembling of intra-arterial balloon catheter.As shown in the figure, the patient end 32 of described pulse pipe 3 is installed on the straight line adapter 5, and this straight line adapter 5 is connected with a conduit 8 again.Described conduit 8 is connected with another straight line adapter 6 again.This straight line adapter 6 can suitably place in the patient body, thereby described patient end 32 is connected to patient body.Described cardiopulmonary bypass machine end 34 cooperates with a Y-connection 4.This Y-connection 4 comprises cardiopulmonary bypass machine portion (CBP portion) 42 and tremulous pulse capsula interna pump portion (intra aortic balloon pump portion, IABP portion) 44.Described cardiopulmonary bypass machine portion 42 is connected with a department of pediatrics cardiopulmonary bypass machine circulation pipe (pediatric CPB circuit tube) 2, and this department of pediatrics cardiopulmonary bypass machine circulation pipe 2 is connected with a straight line adapter 9 again.This straight line adapter 9 can connect by a cardiopulmonary bypass machine 50, thereby makes this cardiopulmonary bypass machine 50 to provide suitable pulse to patient's body by the cardiopulmonary bypass machine end 34 of described pulse pipe 3.The tremulous pulse capsula interna pump portion 44 of described Y-connection 4 is installed on the adapter 7, this adapter 7 can be connected with a tremulous pulse capsula interna pump 60, thereby make this tremulous pulse capsula interna pump 60 be connected, and in patient body, form suitable pulse with two inner cavity (figure does not show) of described pulse pipe 3.Be inserted in the described adapter 7 with reference to 4, one intra-arterial balloon catheters of figure (intra aortic balloon catheter, IAB catheter) 1.The other end of described intra-arterial balloon catheter 1 can be connected with an outer arteries capsula interna pump.
When operation, described cardiopulmonary bypass machine and tremulous pulse capsula interna pump provide suitable pulse by described pulse pipe 3 to the patient.This utility model pulse pipe provides the safety and the pulse flow of homogeneity (homogenous) more more.And described pulse pipe can be installed on any wind-force pulsation machine, such as tremulous pulse capsula interna pump or enhancement mode extracorporeal counterpulsation equipment (enhanced externalcontra pulsation, EECP).This utility model pulse pipe has matching more widely, can mate with cardiopulmonary bypass machine, cardiac assist devices or artificial heart such as it, thereby produce downward pulsating nature homogeneity perfusion stream.
Optimally, the distance between the described patient end 32 and the described pair of inner cavity 36 is enough little, so that reduce the blind area between pulse flow and the patient.In one embodiment, the distance between the described patient end 32 and the described pair of inner cavity 36 is 5-10cm.
Described integrally formed intra-arterial air bag barrier film can be installed on the described pulse pipe by spiral form (spiral), face-to-face form (face to face) or coil form (coil form).And the length of described pulse pipe can be adjusted as required.In the case, the passage 38 of described pulse pipe must keep enough distances from extraction in the described body 31 and with described cardiopulmonary bypass machine end, such as 20cm, so that can not damage the patient in the re-adjustment process of pulse length of tube.
For reducing to pollute and the gas leakage, described pulse pipe is preferably formed such as polrvinyl chloride (PVC) or silicones (silicone) by suitable material.And the integrally formed intra-arterial air bag barrier film of described pair of inner cavity made by Ka Disen (cardiothane), and this material can reduce the intravital globulolysis of patient.In addition, the size of this utility model pulse pipe can change to some extent according to different patients.
Compared with the prior art, this utility model pulse tubular construction is simple, and this simple structure reduces or avoided the side effect of legacy equipment such as existing pulse cardiopulmonary bypass machine.These pulse cardiopulmonary bypass facility have higher operating cost, and need to use with existing heart equipment (such as tremulous pulse capsula interna pump or traditional cardiopulmonary bypass machine) in must use two kinds of technology that standard material is relevant.And, because the conflict between pulse pressure/organ perfusion that the generation of pulse pipe near the perfusion stream of physiology pulse pressure, has therefore thoroughly been avoided and different pulse equipment produces.
With reference to figure 2, according to another embodiment of the present utility model, pulse pipe 3 ' can have the two inner cavity 36 ' that are made of integrally formed intra-arterial air bag barrier film.This pulse pipe 3 ' and above-mentioned pulse pipe 3 are similar, and difference is: in this embodiment, the integrally formed intra-arterial air bag barrier film of described pair of inner cavity 36 ' is outer chamber (extra luminal).This outer chamber is by from the mode of the described pulse pipe of external compression patient's blood flow being produced pressure.The operation of described pulse pipe 3 ' and described pulse pipe 3 are similar, have omitted further description here.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of this utility model certainly with this, and therefore the equivalent variations of being done according to this utility model claim still belongs to the scope that this utility model is contained.
