Description
Technical Field
The present invention relates to medical equipment, and more particularly, to a disposable pulse tube for use in a cardiopulmonary bypass machine and an arterial inner bag pump to achieve stable pulse flow in a patient's body when performing cardiopulmonary surgery.
Background
To ensure proper circulation of the heart of a patient when performing surgery on the patient, particularly in connection with cardiopulmonary related surgery, medical aids such as a cardiopulmonary bypass machine (CPB) or an intra-arterial balloon pump (IABP) are commonly used to maintain proper circulation outside the patient's body.
With the cardiopulmonary bypass machine, the blood in the patient is temporarily diverted to oxidize and circulate in the body, thereby maintaining the circulation until the heart and lung can return to normal function. The intra-arterial sac pump is used for increasing myocardial oxygen supply (myocardial oxygen supply) and reducing myocardial oxygen demand (myocardial oxygen demand), and for increasing cardiac output (cardiac output).
In order to obtain a pulse flow in a patient, the cardiopulmonary bypass machine and the intra-arterial sac pump may be combined using a pulse tube (pulsate tube). However, the conventional pulse tube has a risk of contamination to the patient and a risk of gas leakage during the operation. In addition, the conventional pulse tube cannot obtain a (homogenes) pulse flow close to or homogeneous with the physiological pulse flow of the human body.
Therefore, it is necessary to provide a disposable pulse tube that solves the above problems.
Disclosure of Invention
The utility model mainly aims at providing a disposable pulse tube which can reduce pollution and leakage and simultaneously ensure that the operation of a patient is safer.
Another object of the present invention is to provide a disposable pulse tube, through which a more homogeneous pulse flow can be obtained.
To achieve the above object, a disposable pulse tube for obtaining pulse flow includes: a pipe body; the end part of the cardiopulmonary bypass machine is formed at one end of the pipe body and is connected with the cardiopulmonary bypass machine; a patient end portion formed at the other end of the tube body for insertion into a patient; and a double lumen portion formed between the cardiopulmonary bypass machine end and the patient end. The double-lumen part is provided with an intra-arterial balloon diaphragm which is integrally formed.
In one embodiment, the integrally formed intra-arterial balloon membrane is an internal cavity that directly applies pressure to the patient's blood flow. In another embodiment, the integrated intra-arterial balloon septum is an outer cavity. The outer cavity generates pressure on the patient's blood flow by externally compressing the pulse tube.
Most preferably, the length of the double lumen portion is 45 cm. The pulse tube may be 1.2-1.6 meters long and 11-13mm in diameter. The integrated intra-arterial balloon septum has a volume of 40cm3 and a pulse rate of 10-110 machine pulses per minute. In addition, the distance between the end of the patient and the double-cavity part is 5-10 cm. The integrated intra-arterial balloon septum may be attached to the pulse tube by means of a spiral form, a face-to-face form, or a coil form.
The present invention will be described in detail below with reference to the accompanying drawings by way of preferred embodiments.

Detailed Description
Embodiments of the present invention will now be described. Referring to fig. 1, according to an embodiment of the present invention, a disposable pulse tube 3(disposable pulse tube) includes a tube body 31; a heart-lung bypass machine end (CPB end)34 formed at one end of the pipe body 31 and connected to a heart-lung bypass machine (CPB machine, refer to fig. 4) 50; a patient end (patient end)32 formed at the other end of the tube 31 and inserted into the patient; and a double lumen portion (double lumen portion)36 formed between the cardiopulmonary bypass machine end 34 and the patient end 32.
The double lumen portion 36 may be connected to an external counterpulsation pump (refer to fig. 4)60 by means of a channel 38 provided in the tube 31. The external counterpulsation pump 60 regularly supplies a suitable gas such as helium or carbon dioxide to cause the double lumen section 36 to be inflated or deflated to create a pulse flow that regularly drives the patient's blood. In this case, in order to make the double lumen portion 36 more freely inflatable or deflatable, the double lumen portion 36 preferably includes an integrally formed intra-arterial balloon membrane (intra-arterial balloon membrane). Further, the integrally formed intra-arterial balloon membrane is preferably an inner lumen (intra-luminal) that directly applies pressure to the patient's bloodstream. In addition, the length of the double lumen portion 36 may be 45 cm. The pulse tube 3 may be 1.2-1.6 meters long and 11-13mm in diameter. The integrated intra-arterial balloon septum may have a volume of 40cm3 and a pulse rate of 10-110 machine pulses per minute (machinepulse/min).
Fig. 3 is an exploded perspective view of an intra-arterial balloon catheter (IAB catheter) and a pulse tube according to an embodiment of the present invention. Fig. 4 is a perspective view of the assembled pulse tube and intra-arterial balloon catheter shown in fig. 3. As shown, the patient end 32 of the pulse tube 3 is mounted on a linear connector 5, which linear connector 5 is in turn connected to a catheter 8. Said conduit 8 is in turn connected to another line connector 6. The line connector 6 may be suitably placed in the patient's body to connect the patient end 32 to the patient's body. The cardiopulmonary bypass machine end 34 mates with a Y-connector 4. The Y-connector 4 includes a Cardiopulmonary Bypass (CBP) section 42 and an intra-arterial balloon pump (IABP) section 44. The cardiopulmonary bypass machine portion 42 is connected to a pediatric cardiopulmonary bypass machine circulation tube (pediatric CPB circuit tube)2, which pediatric cardiopulmonary bypass machine circulation tube 2 is in turn connected to a line connector 9. The line connector 9 may be connected with a cardiopulmonary bypass machine 50 such that the cardiopulmonary bypass machine 50 can provide the proper pulse to the patient's body through the cardiopulmonary bypass machine end 34 of the pulse tube 3. The intra-arterial balloon pump portion 44 of the Y-connector 4 is mounted on the connector 7, and the connector 7 can be connected with an intra-arterial balloon pump 60, so that the intra-arterial balloon pump 60 is connected with the double lumen portion (not shown) of the pulse tube 3 and forms a proper pulse in the patient. Referring to fig. 4, an intra-arterial balloon catheter (IAB catheter)1 is inserted into the connector 7. The other end of the intra-arterial balloon catheter 1 may be connected to an external intra-arterial balloon pump.
When running, the cardiopulmonary bypass machine and the intra-arterial bladder pump provide the appropriate pulse to the patient through the pulse tube 3. The utility model discloses the pulse pipe provides safer and more homogeneous (homogen) pulse stream. Also, the pulse tube may be mounted on any wind pulsation machine, such as an intra-arterial balloon pump or an enhanced external counterpulsation device (EECP). The pulse tube of the utility model has wider matching performance, for example, the pulse tube can be matched with a cardiopulmonary bypass machine, a heart auxiliary device or an artificial heart, thereby generating downward pulsation homogeneous perfusion flow.
Optimally, the distance between the patient end 32 and the dual lumen portion 36 is small enough to reduce the dead space between the pulse flow and the patient. In one embodiment, the distance between the patient end 32 and the dual lumen portion 36 is 5-10 cm.
The integrated intra-arterial balloon septum may be mounted to the pulse tube by means of a spiral form (spiral), a face-to-face form (face to face), or a coil form (coil form). Moreover, the length of the pulse tube can be adjusted according to needs. In this case, the pulse tube channel 38 must be extractable from the tube body 31 and be kept at a sufficient distance, for example 20cm, from the end of the cardiopulmonary bypass machine, so as not to cause injury to the patient during the readjustment of the pulse tube length.
To reduce contamination and gas leakage, the pulse tube is preferably formed of a suitable material such as polyvinyl chloride (PVC) or silicone. Also, the dual lumen, integrally formed intra-arterial balloon septum is made of a cadioxan (cadiothane) material that reduces red blood cell lysis in the patient. In addition, the size of the pulse tube of the utility model can be changed according to different patients.
Compared with the prior art, the utility model discloses pulse tube simple structure, this simple structure reduces or has avoided the side effect of traditional equipment such as current pulse cardiopulmonary bypass machine. The pulse cardiopulmonary bypass machine has a high operating cost and requires the use of technology associated with two standard materials that must be used in existing cardiac equipment, such as an intra-arterial capsule pump or a conventional cardiopulmonary bypass machine. Moreover, since the pulse tube generates perfusion flow close to physiological pulse pressure, the conflict between pulse pressure/organ perfusion generated by different pulse devices is completely avoided.
Referring to fig. 2, according to another embodiment of the present invention, the pulse tube 3 'may have a double lumen portion 36' formed by an integrally formed intra-arterial balloon membrane. This pulse tube 3' is similar to the pulse tube 3 described above, with the difference that: in this embodiment, the integrally formed intra-arterial balloon septum of the double lumen portion 36' is the outer lumen (extra lumen). The outer cavity generates pressure on the patient's blood flow by externally compressing the pulse tube. The operation of the pulse tube 3' is similar to the pulse tube 3, and further description is omitted here.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
