Description
Technical field
The present invention relates to manually cure by oxygen therapy field, be specifically related to a kind of oxygen supply device and oxygen therapy method thereof in venous lumen.
Background technology
It is known that the deposit of oxygen is little in human body, it is necessary to continuously feed oxygen from the external world in a steady stream and just can sustain life,
Therefore from the most initial mask oxygen inhalation to nose conduit, hyperbaric oxygen chamber and the Ventilators etc. the most in succession occurred all
It is conceived to by respiratory tract oxygen supply, and has become the important means of various anoxia treatment.But, for some particular patients ', often
Rule oxygen supply method can seem helpless.Such as in the face of the acute lung injury caused due to Serious respiratory tract burn etc., traumatic
Hypertonicity pulmonary edema that hydropneumothorax, sea water cause, SARS etc. cause the patient of pulmonary diffusion function serious hindrance, and its subject matter is also
Do not lie in dysfunction of ventilation, therefore usually cannot effectively save the life of patient through conventional respiratory tract oxygen supply；Meanwhile, special at some
In the case of, the restriction of conventional oxygen supply method also rescue to patient brings many obstacles.So, oxygen supply approach can be changed,
Attempt waiting as supplemental oxygen new method by vein is even oral, walk around this pass of alveolar of diffusing capacity and make oxygen straight
Tap into into blood？
In fact recent domestic never stops about the research in terms of oxygen carrying succedaneum, such as without substrate blood egg
In vain, the circulating protein solution of genetic engineering artificial blood, liposome parcel, perfluorocarbon solution etc., but due to these product process
Complicated, expensive, also have relatively large distance from technology maturation so far, be still difficult to use in clinic.And once should be used in China
Liquid oxygen charging method then includes light quantum blood therapy (UIB), blood-magent therapy, magnesium arginyl amine hydroperoxide Carbamide Peroxide method, light quantum
Liquid treatment etc., but be also respectively present blood drawing oxygenation and feed back some defects such as operation is loaded down with trivial details, blood oxygen carrying content few, less stable.
Summary of the invention
The present invention solves the problems referred to above, it is provided that oxygen supply device and method thereof in a kind of venous lumen.
The technical problem to be solved uses following technical scheme to realize:
Oxygen supply device in a kind of venous lumen, in this venous lumen, oxygen supply device includes that a vein being inserted in vein blood vessel is defeated
Oxygen pipe, stretches out, with described oxygen transferring in vein pipe, the control device that venous blood pipe end is connected, and this control device is passed through for accurately control
Oxygen pressure in described oxygen transferring in vein pipe.
Described control device includes oxygen catheter, effusion meter, piezometer, controller, control panel；Described oxygen transferring in vein pipe end

Oxygen concentration testing instrument, blood inlet end blood oxygen concentration measuring instrument, hemorrhage end blood oxygen concentration measuring instrument be connected respectively to controller, and vein is defeated
Oxygen pipe inserts vein blood vessel part forward end seal, is evenly distributed with nanoscale oxygen therapy hole along sidewall, at oxygen transferring in vein tube hub is
Oxygen therapy passage, oxygen therapy channel end is oxygen inlet, and oxygen therapy passage connects with oxygen therapy hole, and oxygen enters into tube wall from oxygen therapy passage
On oxygen therapy hole, the oxygen oxygenate in oxygen therapy bore end i.e. oxygen transferring in vein pipe outer wall and vein blood vessel, for further effectively control
Oxygen flow processed and improve oxygenation efficiency, is unlikely to because the oxygen in oxygen transferring in vein pipe is too much or very few causes shape in vein blood vessel
Become oxygen content in oxygen bubbles or blood too low, as the 0.6-0.8 that oxygen transferring in vein tube section area is vein blood vessel area of section, quiet
Arteries and veins oxygen catheter pipe thickness is the 3/4 to 4/5 of oxygen transferring in vein pipe external diameter, and in blood, oxygen content is the highest, does not has again oxygen bubbles simultaneously
Generation, oxygen therapy passage is set to curve-like and connect can slow down oxygen gas flow rate further with oxygen therapy hole, raising oxygenation efficiency.
A kind of oxygen transferring in vein method, comprises the following steps:
1), described oxygen transferring in vein pipe is inserted in vein blood vessel, and carries out the back works such as hemostasis sterilization；
2), set on described control panel and be passed through oxygen transferring in vein pipe oxygen pressure as a setting value；
3), described control panel transfer signals to controller, controller controls effusion meter and opens and to oxygen transferring in vein pipe
Interior conveying oxygen, the blood in vein blood vessel and the oxygen oxygenate in oxygen transferring in vein pipe, the oxygen transferring in vein pipe of piezometer monitoring simultaneously
Interior oxygen pressure, keeps flow to be calculated as an opening angle when reaching setting value, and during oxygenate, if occurring, piezometer records
Oxygen pressure higher than setting value, signal is first fed back to controller by piezometer, and controller sends opens control valve order, control valve
Opening an angle and make the oxygen pressure in oxygen transferring in vein pipe gradually reduce, when being reduced to setting value, controller sends cut out control
Valve order processed, if occurring, the oxygen pressure that piezometer records is less than setting value, and signal is fed back to controller by piezometer, and controller is sent out
Go out to increase effusion meter opening angle order, until the oxygen pressure in oxygen transferring in vein pipe is equal to setting value；
4), during oxygenate, oxygen transferring in vein pipe inserts the blood inlet end blood oxygen concentration measuring instrument of vein blood vessel front and back end, goes out
Oxygen content in forward and backward for the oxygenate recorded blood is fed back to controller and shows in control by blood end blood oxygen concentration measuring instrument respectively
Panel, medical personnel revise the setting value of oxygen pressure in oxygen transferring in vein pipe accordingly.
The invention have the benefit that by inserting oxygen transferring in vein pipe in vein blood vessel, oxygen is transported to venous blood
Pipe, walk around diffusing capacity this pass of alveolar and allow oxygen be directly entered blood and with hemoglobin oxygenate, decline at pulmonary function
Pulmonary can be preferably replaced, with membrane oxygenator, oxygen carrying succedaneum or liquid when exhausting or temporarily can not play Oxygenation
Body oxygen charging method is compared, and this apparatus structure is simple, easy to use, be not required to blood drainage to the most external, thus avoids various possibility
Infection, blood oxygen carrying content is high, stability is preferable.
