Abstract
The utility model relates to an oxygenator, which is used for replacing a lung function in a cardiac direct observation operation of extracorporeal circulation. The oxygenator comprises an oxygenation room (7) with a blood inlet (8) and an oxygenation regulating valve (62), a blood storing cylinder (1), a catheter (11), a sleeve (4) with an overflow outlet (9) and a secondary oxygen blowing device (5), wherein, the secondary oxygen blowing device (5) and the oxygen inlet point of the oxygenation room (7) are respectively provided with an oxygen blowing regulating valve (61) and an oxygenation regulating valve (62). The oxygenator has the advantages of compact structure, small priming volume and convenient application. The oxygenator can conveniently and accurately control PO2 and PCO2 at an optimum point at the same time and can also reduce the mechanical destruction of blood composition, the good air exchange function of blood can be maintained, and the oxygenator is favorable for the rehabilitation of patients.
Description
This utility model is a kind of oxygenator, is used for open heart operation with extracorporeal circulation and replaces pulmonary function.
Present various oxygenator mainly divides two types, and a kind of is membrane oxygenator, and its principle is that the structure and the function of anthropomorphic dummy's lung carried out the QI and blood exchange, and the effect of this oxygenator is fine, but expense is very expensive, exceeds the ability to shoulder economically of Most patients.Another kind is a bubble formula oxygenator, mainly is connected in sequence by oxygenation chamber, the storage blood tube that has the heat-exchanging chamber of heat exchanger and have a filter.Its work process is that patient's vein blood and hemothorax enter oxygenation chamber, imports oxygen simultaneously, thereby realizes with CO in the replacement of oxygen blood
2Function, reach the temperature that is applicable to human body through heat-exchanging chamber after, can pump into human body through filtering again.The weak point of this device is that the oxygen amount of infeeding is difficult to be controlled at optimum.When QI and blood when less than normal, the CO in the blood
2Be difficult to abundant discharge, make the partial pressure of carbon dioxide in the blood compare PCO
2Too high; When QI and blood is bigger, can there be too much O in the blood
2, cause patient oxygen intoxication to occur.Bigger in addition QI and blood is unfavorable for patient's postoperative rehabilitation than the destruction that can increase the weight of blood.
The purpose of this utility model is, provides a kind of being easy to that partial pressure of carbon dioxide is compared PCO
2With partial pressure of oxygen PO
2Control to the oxygenator of optimum.
The technical solution that this utility model adopted is: whole oxygenator, comprise the oxygenation chamber that has blood inlet and oxygenate control valve, the storage blood tube that has heat exchanger and filter, it also comprises conduit, has the sleeve and the secondary oxygen blowing device of overfall, wherein conduit one end communicates with oxygenation chamber, the other end communicates with sleeve, sleeve is fixed in the storage blood tube, this sleeve is provided with overfall, below the overfall of the sleeve outside, be provided with the secondary oxygen blowing device, also be provided with an oxygen blast control valve at the oxygen intake place of this secondary oxygen blowing device.
Existing correlation technique all can be used for reference or directly be utilized to above-mentioned oxygenation chamber, storage blood tube, filter, heat exchanger, and above-mentioned secondary oxygen blowing device is one to the oxygen blown device of the effusive oxygenated blood of overfall, and its oxygen flow is controlled by the oxygen blast control valve.
Work process of the present utility model is: patient's vein blood and hemothorax enter oxygenation chamber from the blood flow inlet, utilize the control of oxygenate control valve to import an amount of oxygen simultaneously to oxygenation chamber, blood in the oxygenation chamber fully contacts the back with oxygen and forms oxygenated blood, flow to sleeve through conduit, the bubble in the oxygenated blood in sleeve can be assembled and overflow from blood automatically.Through the secondary oxygen blowing device this oxygenated blood is carried out the secondary oxygen blast, the CO in the further discrete blood
2, the blood after the secondary oxygen blast carries out temperature control through heat exchanger to be regulated, and makes it to be suitable for human body, is oozed out by filter then, oozes out that the size bubble in the blood is all filtered in the process, and the above-mentioned blood that is oozed out by filter promptly can enter in the human body.
Advantage of the present utility model is compact conformation, and priming volume is little, and it is convenient to be suitable for, and can make things convenient for exactly with PO
2Close PCO
2Be controlled at optimum simultaneously, and can reduce mechanical damage, keep the good gas exchange function of blood, help patient's rehabilitation blood component.
Below in conjunction with embodiment this utility model is described further:
Fig. 1 is a structural representation of the present utility model
The described oxygenator of present embodiment is by storage blood tube (1), filter (2), heat exchanger (3), sleeve (4), secondary oxygen blowing device (5), the oxygen that comprises oxygenate control valve (62) and oxygen blast control valve (61) divides flow modulation device (6), oxygenation chamber (7), blood inlet (8), overfall (9), filter course (10), closing guiding tube (11) forms, as shown in Figure 1, wherein guiding tube (11) one ends communicate with oxygenation chamber (7), the other end communicates with sleeve (4), sleeve (4) is fixed in the storage blood tube (1), this sleeve (4) is provided with overfall (9), in sleeve (4) outside overfall (9) below, be provided with secondary oxygen blowing device (5), also be provided with an oxygen blast control valve (61) at the oxygen intake place of this secondary oxygen blowing device.In the present embodiment, the main body of secondary oxygen blowing device (5) is an annular housing, and this annular housing is provided with venthole, and this annular housing is connected with oxygen blast control valve (61) by pipeline.For guaranteeing oxygen blown effect of secondary and the further bubble of eliminating in the blood, present embodiment also locates to be provided with the filter course of being made by expanded material (10) at the overfall (9) of sleeve (4),
In the use, as partial pressure of oxygen PO
2When too high, scalable oxygenate control valve (62) reduces the oxygen inlet of oxygenation chamber (4); Intrinsic standoff ratio PCO when blood
2When too high, scalable oxygen blast control valve (61) increases the oxygen flow of secondary oxygen blowing device (5).
Claims (3)
1, a kind of oxygenator, comprise the oxygenation chamber (7) that has blood inlet (8) and oxygen intake, the storage blood tube (1) that has heat exchanger (3) and filter (2), it is characterized in that: this oxygenator also comprises guiding tube (11), the sleeve (4) and the secondary oxygen blowing device (5) that have overfall (9), wherein guiding tube (11) one ends communicate with oxygenation chamber (7), the other end communicates with sleeve (4), sleeve (4) is fixed in the storage blood tube (1), this sleeve (4) is provided with overfall (9), in sleeve (4) outside overfall (9) below, be provided with secondary oxygen blowing device (5), the oxygen intake place of secondary oxygen blowing device (5) and oxygenation chamber (7) is provided with oxygen blast control valve (61) and oxygenate control valve (62) respectively.
