Description
Technical field
The present invention relates to medical instruments field, especially a kind of ECMO membrane lung rinses droplet collection device.
Background technique
Extracorporeal membrane oxygenation (extracorporeal membrane oxygenation, ECMO), is the one of extracorporal circulatory system
Kind, ECMO can breathe Refractory Severe and/or the critical patient of circulation function failure carries out effective breath cycle support.Its
Principle is to carry out gas through oxygenator (artificial lung) for outside intracorporal blood lead body by pump (it acts on similar artificial heart)
Oxygen synthesis arterial blood injection patient's central aortic or vein are exchanged, part cardiopulmonary substitution effect is played.The basic structure packet of ECMO
Include endovascular prosthesis pipe, connecting tube, kinetic pump (artificial heart), oxygenator (artificial lung), oxygen supplying tube, monitoring system.Wherein move
Power pump and oxygenator are two the most key components.Kinetic pump is otherwise known as artificial heart, and effect is to form power to drive
A Fang Liudong of the blood to pipeline, the function of similar heart, the kinetic pump that clinically there are mainly of two types: roller pump and centrifugation
Pump.Since roller pump is not easily shifted, difficult management, in the preferred centrifugal pump of first aid profession as kinetic pump, advantage is that installation moves
Dynamic convenient, convenient for management, Blood damage is small, has swabbing action in reasonable range of negative pressure, caused by can solving certain reasons
Low discharge problem, centrifugal pump of new generation also easily manipulate children's low discharge.Oxygenator is otherwise known as artificial lung, function be by
Non-oxygen conjunction blood oxygen synthesizes oxygenated blood, and ECMO oxygenator has silica gel membrane type and two kinds of hollow fiber type, silica gel membrane type membrane lung compatibility
Good, rare plasma leakage, blood constituent destroys small, suitable long-time auxiliary, such as supports cardio-pulmonary function waits transplant, infect institute
Respiratory failure is caused, the disadvantage is that exhaust problem, expensive.Hollow fiber type membrane lung is easily vented, and visible blood plasma seeps within 2-3 days
Leakage, blood constituent destruction is relatively large, but is first aid set packet since simple installation is still preferred, if desired, can be in one after the stable state of an illness
Suitable oxygenator is replaced in two days.
According to therapeutic modality and purpose, ECMO mainly has veno-arterial ECMO (VA-ECMO) and vein-vein ECMO
(VV-ECMO) two kinds, VV-ECMO is suitable for only needing the patient of Breathing Suppotion, and VA-ECMO is breathed and recycled branch simultaneously
It holds.
Referring to attached drawing 1, veno-arterial ECMO (VA-ECMO) sets pipe by vena cave (femoral vein or jugular vein), manually
Pump leads to body circulation blood flow in vitro, returns in vivo through arteria carotis or femoral catheter again after the conjunction of membrane lung oxygen, is equivalent to membrane lung
In parallel with Patients with Lung progress, this mode is identical as traditional extracorporal circulatory system.
Referring to attached drawing 2, vein-vein ECMO (VV-ECMO), ECMO draw blood end (mostly femoral vein) and blood back end (mostly
Jugular vein) it is respectively positioned in vena cave, it is equivalent to artificial membrane lung and connects with Patients with Lung, so that patient's arterial oxygen content obtains
To improve, although vein-vein ECMO (VV-ECMO) cannot provide circulatory support, due to required positive airway pressure in its operation
The increase that the reduction of support pressure and coronal arterial oxygen supply, the heart function of patient can also be improved to a certain extent.
Show oxygen for airflow portion in attached drawing 1-2, it is generally the case that pure oxygen or titanium dioxide of the oxygen for air-flow for 100%
The mixed air of carbon and oxygen, containing 5% carbon dioxide and 95% oxygen, conventional arrangement oxygen is for air flow rate and blood flow
It is equal, i.e., 1: 1, the removing of carbon dioxide can be increased for air flow rate by increasing oxygen, but is taken a group photo to oxygen and rung very little, if ECMO is only
For removing carbon dioxide, lesser membrane lung can be selected, blood flow can reduce, and oxygen often selects oxygen, air-flow for air-flow
It is usually 10: 1 with the ratio between blood flow.Vapor can be formed in long-term use process can be aggregated in membrane lung, and interruption improves oxygen and supplies
The flow flush membrane lung of air-flow avoids vapor from being aggregated membrane lung function reduction caused by forming " pulmonary edema ".Even in addition, solid
Body silica gel and solid hollow fiber membrane lung, it is also possible to because of lesser damaged formation gas embolism, it is therefore necessary to maintain in membrane lung
The pressure of blood flow side is higher than air-flow side, in oxygen for installation pressure relief valve or pressure servo adjusting controller on gas flow tube road, or
Person keeps the level height of membrane lung to be lower than patient, can pass the gas through membrane lung and enters the risk of blood flow and is preferably minimized.
It is found in the practice operation used by ECMO, two outlets of the meeting below membrane lung during rinsing membrane lung
There is drop in (one is relatively large in diameter, and a diameter is smaller), and common practice is that the drop is directly dripped and evaporated on the ground,
Without will do it any medical response.It can not determine whether these drops contain pathogenic microorganisms, cause environmental pollution, or even disease
The propagation of opportunistic pathogen.This random disposal options to drop, it is both unhygienic, drop can not be effectively utilized, is as ECMO
The no monitoring index to break down provides valuable data and reference for the ECMO operation and maintenance of next step.

Wherein, the part of several keys is referred in the key points for operation, comprising:
One, the mode of blood vessel approach, is divided into:
1. one artery of vein (VA) approach (is applied to heart to support, be also applied for Breathing Suppotion)；
2. one vein of vein (VV) approach (does not provide haemodynamics support, is mainly used for Breathing Suppotion, because of which
It can avoid damage main artery, and can avoid that Thrombosis occurs)；
Mono- arterial-venous approach of 3.AV (when being only applied to require lower to blood flow, especially for removing CO2)
Two, it is intubated
" intubation (cannula) " word is exclusively used in indicating to be inserted directly into the conduit merging that blood vessel carries out ECMO, to be different from
Conduit in every other device.The resistance of blood flow of blood vessel approach intubation is directly proportional to the length of pipeline, the biquadratic with radius
It is inversely proportional.Therefore, the internal diameter of intubation is the main factor for determining resistance of blood flow.Other factors such as side opening and tip attenuate
Resistance of blood flow can be influenced, and resistance of blood flow can as the flow rate increases and increases.Therefore, every set is familiar with before intubation to lead
The characteristics of pipe.
Three, centesis
(1) piercing method
It can carry out in the following manner puncture and intubation: 1) cut and set pipe；2) couple puncture, seal wire positioning and step by step
It expands (Semi-Seldinger technology)；3) exposed incision and Semi-Seldinger casing implantation is used in combination or 4) opens
Chest is postoperative to be directly placed in atrium dextrum and aorta for casing.In newborn and young children, typically required row jugular vein
Cut casing implantation.Percutaneous puncture casing implantation is usually used in two years old or more children and adult one vein ECMO of vein
In.Direct heart canula implantation is used to be detached from the patient of CPB (extracorporal circulatory system) in situations in the surgery room, can be covered using CPB
Pipe.
One transvenous approach of vein can be used double-cavity puncture conduit and establish access, or set in two different venipunctures
Pipe establishes access.
(2) puncture and intubation technology
It needs to give aggressive dosage liver rope (usual 55-100U/kg) before merging casing, even if patient's blood coagulation disorders and just
In bleeding.
1, directly cut casing implantation: casing merging carries out usually in ICU, should carry out sufficient Aseptic sterilisation, and
It should be carried out by the Zhi Guan group of operating room.It is necessary to give patient's deep sedation/anesthesia and flesh pine, inhibit autonomous respiration,
To avoid air embolism.The anesthesia of row local skin.Cut exposure blood vessel.Try not directly to press blood vessel to avoid blood vessel hair
Raw spasm.Vasopasm can be reduced by administering locally to lidocaine or papervine.Above and below casing merging point respectively
Two root knot bindings are bypassed into blood vessel.Vein gives heparin (50-100U/kg)) after, ligation blood vessel distal end.Blood vessel proximal end blood vessel
Clamp closes.Blood vessel is cut, casing is placed in.If blood vessel is very small, if casing merging is difficult, or if angiogenesis convulsion
It is very useful to give firm reinforcing suture at the proximal edge of blood vessel for contraction.Blood vessel is surrounded on casing, and is tied
It pricks, conduit often passes through one " sheath " ligation in the blood vessels, in order to later period Lumen catheter.In femoral artery puncture, use is non-
The method of intubation (the semi-Seldinger puncture and intubation method that see below) of ligation can ensure that sufficient blood flow through periphery of spigot
Arterial distal is flowed to, to ensure the perfusion of remote organization.
2, percutaneous casing implantation: casing merging usually carries out in work ICU, should carry out stringent Aseptic sterilisation and prepare,
It need not be completed to set pipe by the Zhi Guan group of operating room but should done some preparations, when complication occurs for percutaneous puncture catheter, then
It needs medical surgery team to carry out angitomy and sets pipe.Conventional compact blood vessel inner sleeve is placed first, this is often safest way.Pass through
It is intravascular that pumpback blood and the endovascular blood pressure of measurement can confirm that conduit is located at.After sufficient Aseptic sterilisation processing, it will pass through
Puncture cannula is sent into seal wire, takes out and punctures conduit, expands skin step by step using skin device is expanded.The expander finally used is equivalent to wait be placed in
The tube core of casing.Under conditions of using existing equipment, percutaneous puncture casing implantation needs two people's operations: a people is by expander
Expander is covered on seal wire and delivers, another people presses blood vessel during replacing expander to prevent bleeding.Work as use
Seldinger technology punctures, and when using large size casing and expander, is both needed to check seal wire after each expansion, this is very heavy
It wants.It should be extracted out when seal wire is twisted together or is bent and more renew seal wire.Facilitate casing positioning using ultrasound and fluoroscopy.Work as master
After seal wire merging, the heparin of aggressive dosage can be given at any time.
3, Semi-Seldinger technology: the technology can carry out in ICU, and patient needs to anaesthetize, and must be in aseptic condition
Lower progress.A piece small-sized venous infusion catheter (20G) is penetrated skin and penetration rate of blood through notch distal end by exposure blood vessel after incision
Pipe.Pumpback have blood stream go out confirm puncture tube be located at it is intravascular, hereafter give heparin.Hereafter it can be placed in by this root conduit big
Number seal wire.Expander is used step by step, it is final to be placed in ECMO casing.Hereafter, wound skin is covered on casing and is sutured, outside
The percutaneous puncture catheter of standard is seemed in sight.The advantage of the relatively simple percutaneous puncture catheter of this technology is that its speed is fast, can
With the pipe diameter size of accurate judgement blood vessel, and can be with flexible choice mode of operation.
