Abstract
An intravenous oxygenating device is composed of an oxygen delivering tube, a gas diffusing unit to be inserted in vein and a jointer between said oxygen delivering tube and gas diffusing unit. Said gas diffusing unit consist sof a bunch of fibrous tubes and a fibrous tubes converging member for controlling their diffusion degree.
Description
Technical field
The invention belongs to and venous blood is transformed into the oxygenator that contains the higher blood of oxygen, particularly a kind of oxygenator that inserts the human body use.
Background technology
Be difficult to keep ventilated patient in acute shock lung, multiple wound, the operation on trachea, particularly acute respiratory distress disease (ARDS) patient because there is serious pathological change in pulmonary, improves respirator and can not improve patient's blood oxygen concentration for oxygen concentration.For this type of patient, need give suitable gas exchange to improve the incorrigible hypoxemia of its stubbornness, avoid further injury of lung and other organ injury.ECMO (Extracorporeal MembraneOxygenation, ECMO) be present normally used a kind of method, it is with outside patient's vein blood or Arterial system inner blood (oxygen content the is lower) lead body, through the external higher blood of membrane lung oxygen synthesizing oxygen-containing, and will contain the higher blood transport of oxygen to body.The problem that this kind method exists is: need to insert at least two pipelines, need the artificial heart support simultaneously; Patient's palpus whole body heparinization; Owing to, may cause patient's hemodynamics sharply to change with outside the blood lead body; Blood samples of patients contacts with artificial nest, and hemodynamic change has activated blood coagulation reaction and inflammatory reaction simultaneously, not only cause a large amount of forfeitures of thrombin, patient's abnormal bleeding increases, and, inflammatory reaction can cause the important organ damage, has delayed patient's recovery; Artificial blood pump and inflammatory reaction all can cause hematoclasis.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of intravenous oxygenation device to realize oxygenate in the body,, reduce complication, help patient's rehabilitation as early as possible, in addition, also can reduce the operation cost, simplify the operation to improve the safety of operation.
Technical scheme of the present invention: function and the characteristics that insertion body angular vein directly carries out gas exchange according to oxygenator are carried out structural design, and described oxygenator comprises oxygen catheter, inserts the gas dispersion device and the joint that is connected oxygen catheter and gas dispersion device of body angular vein; The boundling member is restrained and disposed to the gas dispersion device for the fiber that is formed by the plurality of fibers pipe, and an end of joint is connected with the fiber tube bank, and the other end is connected with oxygen catheter.
The function of boundling member is that control constitutes the fiber pipe misconvergence of beams of gas dispersion device or adjusts the divergence that fiber is restrained, and both can be fixed, also can be adjustable.So-called fixed, be meant and the position relative fixed of fiber tube bank that can be designed to have concurrently the bullet of guide function or the assembly of bullet and ring bodies, the free end of fiber tube bank inserts the boundling member of above-mentioned shape and structure and is connected with it.So-called adjustable, be meant the divergence that can adjust the fiber pipe bundle, can be designed to the collar, this collar is sleeved in the fiber tube bank, can slide along the fiber tube bank, thus the adjustment of realization fiber pipe divergence, if the boundling member is the collar, intrafascicular each the fiber pipe free end sealing of fiber pipe.
The fiber that constitutes the gas dispersion device is restrained and the contact area of blood in order to increase, the guiding rod member can be set, this guiding rod member inserts the fiber tube bank by the sealing ring of installing on the joint, the boundling member that its insertion end and fiber tube bank free end are connected is connected and passes the boundling member, and guiding rod member and sealing ring form moving sets.Therefore, joint is slided along the rod member that leads, just can make each fiber pipe bending of fiber tube bank and disperse the contact area of increase and blood.The guiding rod member both can be to have the hollow pipe that guiding, blood drawing, injection are used concurrently, can be again only to have a solid hopkinson bar of guide function.
In order to derive the waste gas in the blood, can set out trachea, the boundling member adopts the assembly of bullet and ring bodies, and the free end of fiber tube bank is connected with the ring bodies that constitutes the boundling member, escape pipe inserts the fiber tube bank by joint, and its insertion end and fiber tube bank free end are combined into one.
The present invention has following beneficial effect:
1, uses intravenous oxygenation device of the present invention to carry out gas exchange, only need be inserted into the human body epicoele and/or postcava gets final product, do not need extracorporeal circulation pipeline and artificial heart.
2, use intravenous oxygenation device of the present invention, blood samples of patients and artificial surface contact area are little, and therefore the change of no blood kinetics is disturbed little to blood constituent to the activation of blood.
3, little to the blood destruction, avoided the destruction of artificial blood pump to blood, alleviated the damage of inflammatory reaction to body.
Wound is little, simple to operate when 4, performing the operation.
5, simple in structure, cost is low, is easy to make.
