Abstract
The invention discloses a disposable exhaust-free liquid-replenishing blood transfusion apparatus. According to the disposable exhaust-free liquid-replenishing blood transfusion apparatus disclosed by the invention, the bottom of a dropping funnel is downwards extended by utilizing a liquid detention phenomenon emerged on the lower section of an infusion tube after the dropping funnel of the traditional blood transfusion apparatus is empty so that the dropping funnel becomes a lengthened dropping funnel, and then a small amount of liquid is detained in a cavity of the lengthened dropping funnel after a previous bag is empty. The disposable exhaust-free liquid-replenishing blood transfusion apparatus is characterized in that the liquid is directly replenished after the previous bag is empty, and then the lengthened dropping funnel is pinched so that a liquid level inside the cavity of the lengthened dropping funnel is raised to keep liquid column pressure, and therefore, troubles, waste and port infection which are caused in such a way that liquid replenishment is carried out by downwards and outwards discharging the liquid and exhausting air by repeatedly opening a liquid outlet port and probable patient blood exposure events are prevented, the fact that a small amount of the air enters a human body through a pintle of a transfusion needled, which is possibly caused by reconnecting the transfusion needle is prevented, and then occupational infection probably caused in such a way that nurses frequently inspect and hemorrhage dropping liquid stains the hands of the nurses is prevented; residual liquid is prevented from being generated in an infusion bag; and the residual liquid inside a blood transfusion bag and the infusion bag can be transfused into the human body. The disposable exhaust-free liquid-replenishing blood transfusion apparatus disclosed by the invention is used for clinically continuous infusion and transfusion treatment.
Description
Technical field
The present invention relates to a kind of medical disposable transfusion set, relate in particular to a kind of after previous transfusion bag, infusion bottle or transfusion bags (below be referred to as infusion vessel) are dripped sky, need not be opened to the blood exchange transfusion set that air that liquid interface discharges the stagnant liquid of tube for transfusion hypomere intracavity and epimere intracavity downwards just can continue liquid (note: do not drip the problem that can enter air in the transfusion lumen after empty because of there is not infusion vessel in it) so following it is abbreviated as " disposable exempt from aerofluxus continue the liquid blood exchange transfusion set ".
Background technology
For a long time, (must set up venous access with common liq before owing to blood transfusion in the clinical transfusion blood transfusion, blood transfusion end eventually needs to use the common liq washing pipe, sometimes also can use the blood transfusion path and drip defeated other medicinal liquid, so (refer to toward blood exchange transfusion set's internal-filling liquid defeated fully) in the preparation title transfusion and blood transfusion), make a problem of nurse's worry be: even the nurse can operate meticulously, [note: the present invention abbreviates it as " dropping funnel " still can not to avoid being arranged on Murphy type burette fully; Abbreviate the transfusion catheter that is fixedly connected on dropping funnel top/blood filter top as " dropper " (note: 1. because of it is the transfusion catheter that is positioned at the top/top of dropping funnel, so claim dropper; 2. the symbol "/" in the file of the present invention refer to " or "); Be arranged on dropping funnel top, blood filter top, dropper upper end slotting bottle adapter, insert the slotting bottle connecting device that bottle connects pin prior arts such as (containing side opening pin, angle pin and connecting pipe thereof etc.) and be referred to as " connecting a bottle device "; The blood exchange transfusion set's feed liquor path (for example: be set directly at company's bottle device on dropping funnel top or blood filter top, be furnished with blood exchange transfusion set's feed liquor path of the prior aries such as company's bottle device of dropper) that is arranged on each style on dropping funnel top or blood filter top is referred to as " feed liquor interface "; Be fixedly connected on dropping funnel bottom each style prior art transfusion catheter (for example: straight tube shape transfusion catheter, the lower end of its plastic tube is connected with the transfusion catheter of short section colloid pipe, offers the transfusion catheter of grafting dosing three ports etc.) be referred to as " tube for transfusion "; The blood exchange transfusion set's fluid port that is arranged on the prior aries such as mammiform joint, medicated cap button joint, moveable cap button joint, transfusion three-way cock of tube for transfusion end is referred to as out liquid interface (also claiming the tube for transfusion end fitting); The spy gives explanation] enter little air in that tube for transfusion on the bottom and form aeroembolism, sometimes then show as more bubble attached on the tube for transfusion inwall, its main cause is: when nurse's pinching dropping funnel suction infusion vessel (refers to infusion bottle, when transfusion bag) action of interior liquid is violent slightly slightly soon, the liquid-column impingement that water dropper enters the dropping funnel intracavity produces bubble at the liquid that is introduced into the dropping funnel intracavity, at bubble as yet not during the liquid level of emersion dropping funnel intracavity, just the liquid that is accompanied by in the dropping funnel enters in the tube for transfusion, especially those thick liquids, not only be easy to produce bubble, and the speed of bubble floating is very slow, generate easily when in addition, excessively tortuous and topping up speed is slow at tube for transfusion attached wall bubble (this be because liquid be flow forward along the bottom of horizontal/tilting tube for transfusion inner chamber due to) and aeroembolism.For the aeroembolism in the discharge tube for transfusion and/or attached to the bubble on the tube for transfusion inwall, nurse's finger commonly used springing tube for transfusion makes bubble, aeroembolism come-up, when not only its troublesome poeration takes power consumption, and it is often tiny because of tube for transfusion, especially the aeroembolism of tube for transfusion hypomere intracavity is upwards discharged, how undesirable its effect is, this is because aeroembolism is bearing the pressure of its top fluid column, the tension force of its inside is big (just as Fructus Kaki is pressed into Fructus kaki Siccus), make the outer cylinder surface of aeroembolism be close to the tube for transfusion inwall, be difficult to form convection current.Under desperation, the nurse usually is outwards many downwards some liquid of discharging, till discharging fully to the bubble aeroembolism, consequently: not only cause waste, but also can influence therapeutic effect and cause the ward to be polluted.
For a long time, at clinical transfusion, in continued access liquid (the calling continuous liquid in the following text) work of blood transfusion, make patient's psychentonia and nurse that a very worried problem is: empty and in time do not found or when having little time continuous liquid (for example: the on night duty liquid that runs into the multidigit patient of nurse drips sky simultaneously) by the patient in last bottle fluid drips, air can enter tube for transfusion " epimere " intracavity, some problems of Chan Shenging are therefrom: 1. when tube for transfusion epimere intracavity enters " short section " air, responsible nurse makes tube for transfusion become the flat air upwards extruded tube for transfusion on usually tube for transfusion being wrapped at full tilt and oneself pointing from bottom to top, sometimes need the success of repeatable operation ability, its operation very bothers when taking power consumption; 2. when entering " long section " air in the tube for transfusion, the nurse must be opened to liquid interface [referring to separate transfusion needle or extract the tube for transfusion end fitting in the interface of needleless (transfusion) seal nipple] earlier and discharge the stagnant liquid of tube for transfusion hypomere intracavity and the long section air of epimere intracavity downwards, make tube for transfusion topping up again then, then reconnect and proceed to drip and fail, not only its operation very bothers, easily cause interface and ward to pollute, and often the discharge of the strict liquid that limits is arranged and affect the treatment and cause waste because of discharge, the especially precious liquid of liquid or to therapeutic dose; 3. be opened to liquid interface repeatedly and reconnect transfusion needle, not only easily cause little air and enter human body through the transfusion needle pintle, and when operation, stain nurse's hands is stained with by its hemorrhage (being exactly that blood samples of patients exposes in fact) dropping liquid regular meeting that goes out on liquid interface and the transfusion needle pintle, and the danger that is infected (occupation is infected) by accident is arranged; 4. drip the problem that can enter air in the tube for transfusion of empty back owing to worry dropping funnel, the nurse often needs to make an inspection tour continually; Especially patient and accompany the people always to worry that air can enter human body and feels fear and raise a cry of warning and influence other people and have a rest, or the liquid in infusion bottle is just called when not dripping off as yet and is urged the nurse to change liquid or pull out pin for it, nurse or pull out pin because of the busy liquid of being with, this shows nurse, patient and accompany people three parts that psychological burden is all arranged; Nurse particularly, in fact the process of whole working is exactly a kind of process of height psychentonia.For preventing medical care problem, permitted great medical institutions nurse's office desk and chair not is set, the nurse is maked an inspection tour without a break; Designer of the present invention heard once that Guangzhou several nurses of Affiliated Hospital of medical university complained its unit 5. be opened to liquid interface repeatedly and carry out the discharge opeing aerofluxus, destroyed transfusion device, blood exchange transfusion set's seal, do not meet the essence spirit of transfusion and blood transfusion health; 6. for preventing the trouble due to the tube for transfusion air inlet, drip when defeated when adopting transfusion bag, overwhelming majority nurse is that deliberately the pilot port of the company's of opening bottle device or attached being assigned in of not planting are not plugged in the connecting pipe that bottle connects pin, its result can cause in the transfusion bag, generate residual liquid in dropping funnel and the whole piece tube for transfusion, nurses often are with liquid to pull out pin because of the patient calls, or abandon in the lump together with the residual liquid of transfusion bag, transfusion device and intracavity thereof, according to survey, generally all 20 milliliters upper and lower, this is the unacceptable but problem of inconvenient processing.
For a long time, in clinical transfusion/blood transfusion work, perplexing another problem of nursing the boundary is: behind the fluid drips sky of dropping funnel intracavity, tube for transfusion hypomere intracavity have the fluid stagnation phenomenon [the liquid holdup phenomenon that the tube for transfusion hypomere is presented behind the last bottle fluid drips sky, the present invention abbreviates it as " liquid stagnates "; The liquid holdup phenomenon that the tube for transfusion hypomere was presented when transfusion/blood transfusion finished, the present invention abbreviates it as " residual liquid "; Explanation hereby], its main cause is: there is pressure in intravenous; Secondly, its residual liquid/dispersed phase holdup what may with the individual variation of venous pressure, the viscosity of liquid, the proportion of liquid, the thickness degree of tube for transfusion, the length of tube for transfusion [for example: the transfusion device that is provided with dropper, its tube for transfusion of blood exchange transfusion set is shorter relatively, do not establish the dropper transfusion device of (referring to be directly arranged on the dropping funnel roof) with connecting the bottle device, its tube for transfusion of blood exchange transfusion set is longer relatively], position during patient's transfusion/blood transfusion, the position of transfusion, the height that infusion bottle hangs and the circuitous degree of sinuous song of tube for transfusion hypomere etc. are relevant, and (therefore, " tube for transfusion epimere " of the present invention is meant the empty tube for transfusion of that section that enters air after the fluid drips sky of dropping funnel intracavity; " tube for transfusion hypomere " of the present invention is meant that section tube for transfusion that presents stagnant liquid/residual liquid phenomenon after the fluid drips sky of dropping funnel intracavity, and it is for the empty tube for transfusion of that section of the liquid liquid level top that stagnates.So " tube for transfusion epimere " of the present invention reaches " tube for transfusion hypomere " is a generalized concept, also can be described as a kind of replacement speech, describing so can be too not awkward-sounding, be not that tube for transfusion is equally divided into 3,5,7,9 ... " epimere " shown in after the section reaches " hypomere ", and neither divide tube for transfusion equally is 2,4,6,8 ... " epimere " shown in after the section reaches " hypomere ".In other words, the present invention's so-called " tube for transfusion epimere " is meant when transfusion and blood transfusion, as far as possible the position of infusion bottle, transfusion bags is heightened, make tube for transfusion be in vertical state substantially, make not overbending of tube for transfusion in other words, in this case, the empty tube for transfusion of that section that is presented after the fluid drips sky of its dropping funnel intracavity, so " tube for transfusion epimere " of the present invention reaches " tube for transfusion hypomere " is relative, its length is roughly, is not the epimere and the hypomere of traditional sense; Below no longer repeat specification).Especially precious liquid or have the residual and children's of the strict liquid that limits to drip residual and vial of liquid residual of the liquid when defeated to therapeutic dose not only can cause waste, and can affect the treatment.

Be the continuous liquid inconvenience of avoiding the tube for transfusion air inlet to be caused, The First Affiliated Hospital of Kunming Medical School emergency department adopts the conduit of double headed roller pin that several bottles of liquid are ganged up (series connection) and infuses together, but not all liquid can be ganged up mixing, and also has the arrangement of sequencing when fluid infusion.
The inside and outside CCU of section of (Guangzhou) No.1 Hospital Affiliated to Zhongshan Univ. cardiovascular has used a kind of advanced person's infusion pump in recent years, have that fluid drips in the liquid container is empty reports to the police, regulates multiple functions such as dripping speed and control transfusion total amount automatically, but when transfusion finishes, still exist tube for transfusion hypomere intracavity to have the problem of residual liquid; Higher because of its cost in addition, be difficult to spread to public ward in a short time, especially the medical institutions of economically underdeveloped area.
State Intellectual Property Office on April 2nd, 2002 announced a kind ofly integrate general transfusion, microdroplet transfusion, pressure transfusion, anti-liquid residue, resistant to blood backflows and infusion bottle drips empty advanced transfusion device (patent name: disposable multifunction safe transfusion system of closing automatically, the patent No.: ZL02231787.2), its defective is: 1. because dropping funnel top " terminal phase of intravenous injection device for auto closing valve " inlet of close transfusion device automatically has the new problem that causes having in dropping funnel and the whole piece transfusion lumen residual liquid when the transfusion end; 2. in the preparation of transfusion and blood transfusion, (refer to be equipped with defeated) toward transfusion device, blood exchange transfusion set's internal-filling liquid, because the negative pressure that its intracavity generated behind the pinching dropping funnel can make " terminal phase of intravenous injection device for auto closing valve " to be in closed condition, and the defective that causes being difficult in dropping funnel and the transfusion lumen topping up is arranged.
(the patent No.: ZL00239693.9 that State Intellectual Property Office has announced a kind of " anti-liquid residue formula transfusion device ", the day for announcing: calendar year 2001 JIUYUE 26 days) and a kind of " disposable anti-liquid residue formula pressure transfusion/blood device " (patent No.: ZL03223871.1, the applying date: on March 3rd, 2003), its defective is: 1. the cost of two of its key technology anti-adverse current check valves is higher; 2. in the middle of the patient who is in hospital, drip continuously every day defeated more than two bottles the patient of liquid in the majority, because its dropping funnel upper and lower respectively has an anti-adverse current check valve, when entering air in the empty discovery of the last bottle fluid drips transfusion lumen, even if short section air or bubble, can not go up row, can only adopt the method that is opened to liquid interface to discharge transfusion lumen interior stagnant liquid and air downwards; Because the discharge of stagnant liquid or repeatedly discharge can affect the treatment and cause waste on the contrary, so think, should " anti-liquid residue formula transfusion device " reach " preventing liquid residue formula pressure transfusion/blood device " suitable patient's use of dripping defeated one bottle of precious liquid; If the 3. discharge of chemotherapy medicinal liquid also can cause the ward to be polluted; 4. be opened to liquid interface repeatedly and reconnect, cause easily not only that interface pollutes and little air enters human body through the transfusion needle pintle, and the hemorrhage dropping liquid regular meeting on its pintle is stained with stain nurse's hands, the danger that is infected (occupation is infected) by accident is arranged; 5. can not rinse the bottle chamber of precious liquid and wash and splash into human body, for example: one bottle 50 milliliters albumin is 500 yuan, and the bottleneck bottleneck is exactly 5 yuan for residual 0.5 milliliter, and residual 1 milliliter is exactly 10 yuan.
Each introduction of (Guangzhou) No.1 Hospital Affiliated to Zhongshan Univ.'s Vasculocardiology Deparment and emergency department has in recent years been used a kind of disposable fine setting transfusion device and (has also been claimed " disposable titration adjusting transfusion device ", the place of production is respectively: Irish Abbott Laboratories company limited and Spain), characteristics are: can (belong to the category that manual adjustments consumptive material class is dripped velocity modulation joint valve gear because titration actuator and habitual race folder formula are dripped fast actuator according to doctor's advice and titration actuator, so the present invention is referred to as it " dripping fast actuator ", so-called " titration actuator ", a kind of exactly adjustable type of transferring the files drips fast actuator) the disposable milliliter number that per hour sets that fast regulates exactly of sign on the handle, screw handle one thoughtful dead point and can be transferred to maximum, be minimal to and close, thoroughly exempted the nurse and seen the clock and watch number and drip number and regulate race folder formula back and forth and drip the trouble that fast actuator brings, but these two kinds of advanced persons' disposable fine setting transfusion device exist equally dropping funnel drip empty back tube for transfusion epimere intracavity can enter the problem of air and transfusion when finishing tube for transfusion hypomere intracavity the problem of residual liquid is arranged.
Tube for transfusion hypomere intracavity had the problem of residual liquid when the disposable titration tubular type transfusion device of the popular use of China's medical institutions' department of pediatrics at present existed problem that tube for transfusion epimere intracavity behind the fluid drips sky in the dropping funnel can air inlet and terminal phase of intravenous injection equally.
Patent Office of State Intellectual Property Office has announced a kind of patent of invention (patent name: transfusion device exhaustor on November 22nd, 2000, the applying date: 2000.01.21, the patent No.: ZL00222169.1), its defective is: 1. drip continuously defeated (changing-over) many bottles of liquid or add when pushing away medicinal liquid as the patient with severe symptoms, airway 3 be must open repeatedly and aerofluxus or dosing carried out, have and cause that liquid spill and interface is stained with the possibility of stain, this is because the pressure of exhaustor 8 inner chambers comes from advancing of it, liquid outlet, that is to say on its input duct fluid pipeline switch all is not set, inconvenience control, to carry out the discharge opeing aerofluxus identical with being opened to liquid interface for its exhaust mode, and it also is a kind of open deflated infusion set in a word; Even if 2. the connection tube 2 of exhaustor 8 bottoms of second kind of embodiment does not put in the intracavity of exhaustor 8, the also problem that can cause the residual liquid amount to increase, this is because exhaustor 8 is containers, special-purpose anti-residual liquid device (for example, exhaustor 8 can be sling and then can make the residual liquid of its intracavity import the suspender etc. of human body naturally) is not set; In case 3. enter air in the exhaustor 8, must open airway 3 discharges the method that its discharge or employing are opened to liquid interface (exhaustor 8 as shown in Figure 3) downwards with air, this is because the connection tube 2 on exhaustor 8 tops has put in the intracavity of exhaustor 8, can not upwards thoroughly discharge the air of (drive in the wrong direction and discharge) exhaustor 8 intracavity through tube for transfusion, be accompanied by liquid constantly enter or when exhaustor 8 changing positions, the air that are trapped in the exhaustor 8 have the danger that enters human body.
The patent No. is that ZL200420082693.5 disposable uses negative pressure fluid stopping transfusion device (Granted publication day 2005.10.12) and the patent No. to end liquid transfusion device (manufacturing enterprise: Europe, Zhejiang health care spirit armarium company limited automatically as the disposable use of ZL200320131818.4, phone: defective 0576-85289098) is: not only can not be with the residual liquid input human body of tube for transfusion hypomere intracavity, and when transfusion finishes, can cause generating in the whole piece tube for transfusion residual liquid, especially medicinal liquid and the infantile infusion in the fractional pack small container, its residual liquid amount is relatively large with the ratio of setting amount of infusion, and responsible medical worker is difficult to accept.
For a long time; in the nursing procedure at the whole end of blood transfusion; the nurse understands usually that one bottle of common liq of changing-over carries out washing pipe in order to avoid waste; but because existing blood exchange transfusion set (as: Weihai City Medical High Polymer Co., Ltd; Zhejiang Lingyang Medical Appliances Co., Ltd; ShangHai ShuangGe Industry Co., Ltd of the two Columba livia group of China; GuangDong LongXin Medical Appliance Co., Ltd; the Jiangxi flood reaches blood exchange transfusion set's product of producers such as medical apparatus and instruments company limited) can not rinse transfusion bags and wash and splash into; the nurse normally will be attached in the bag and the blood that remains in the bag mouth bag neck abandons in the lump with bag; not only cause waste, and can affect the treatment.In addition, when this very red bloodstained transfusion bags is dropped, not only can cause psychology to stimulate, and the medical worker also can feel unfortunately with helpless to the patient.The reason that residual liquid generates in the transfusion bags is: 1. blood is viscous liquid, easily sticks on the transfusion bags inwall and toward current downflow; 2. can enter air for preventing that dropping funnel from dripping in the tube for transfusion of empty back, part nurse in the operation of blood transfusion, deliberately the do not plant connecting pipe or the pilot port of companys of opening bottle device not, because the bag mouth support has strutted near the bag wall it, is accompanied by the outflow of blood and generates due to the negative pressure; Can there be difference in what of its residual liquid because of the quantity of bag mouth and the difference of transfusion bags specification and production method, mostly between the 10-15 gram.
During the underway minor operation of the operating room of part hospital (as Guangdong Provincial TCM Hospital), custom is dripped defeated with blood exchange transfusion set and common liq (as Dextrose and Sodium Chloride Inj. etc.), just changing-over transfusion bags is where necessary transfused blood, because the mesh of blood filter is relatively large, the foreign body microgranule that may exist in the medicinal liquid has the defective that enters human body.
Summary of the invention
The objective of the invention is to solve the problem that after existing blood exchange transfusion set's dropping funnel drips sky, air can be entered in its transfusion lumen and cause continuous liquid inconvenience, design principle of the present invention be utilize existing transfusion device, blood exchange transfusion set's dropping funnel drip empty after the stagnant liquid phenomenon that presented of its tube for transfusion hypomere intracavity design, provide a kind of liquid interface that need not be opened to discharge the blood exchange transfusion set that the stagnant liquid of tube for transfusion hypomere intracavity and the air of epimere intracavity (refer to dropping funnel drips can not enter air in its transfusion lumen after empty) just can continue liquid downwards.The present invention also aims to: 1. the blood exchange transfusion set who is provided can be with the input of the residual liquid in transfusion bags, tube for transfusion human body; 2. can prevent from the contingent blood incident of patient and expose blood to be stained with the occupation infection that stain nurse's hands may cause; 3. when adopting the blood exchange transfusion set to drip loading liquid, the foreign body microgranule that may exist in the energy filtering medicinal liquid can prevent to generate in the transfusion bag residual liquid.
The present invention disposablely exempts from the continuous liquid blood exchange transfusion set of aerofluxus and has solved above-mentioned technical problem by providing a kind of, it by (as everyone knows) mutually perforation feed liquor interface, blood filter, tube for transfusion, go out liquid interface and newly-installed extended type dropping funnel is constituted; Described feed liquor interface can be connected perforation with the bag mouth (it comprises the bottleneck of infusion bottle) of transfusion bags; So-called extended type dropping funnel is meant under the prerequisite of the function of the dropping funnel that does not change existing blood exchange transfusion set, and the bottom extension downwards of dropping funnel is made it to become extended type dropping funnel (referring to longer than existing dropping funnel), and then after the fluid drips sky in (its length with) in other words previous infusion vessel, can make its (referring to the extended type dropping funnel) intracavity that a spot of liquid holdup (being as the criterion) is arranged, in order to the operation of continuous liquid; Describedly go out liquid interface and can be connected perforation with the feed liquor interface of transfusion needle set [referring to implantable intravenous transfusion needle set ,] as transfusion needle, needleless (transfusion) seal nipple, venous infusion catheter, blood taking needle, remaining needle etc.[note: designer of the present invention has consulted pertinent literature with regard to essential features problem of the present invention and has specially interviewed Guangzhou Tumor Hospital Attached to Zhongshan Univ. VIP Clinic and recruited favour virtue nurse practitioner length, the cardiovascular surgery CCU Xue Wei of Guangzhou No.1 Hospital Affiliated to Zhongshan Univ. China nurse-in-charge, nurse-in-charge comrade Luo Qiyu of Genneral Surgery of attached overseas Chinese hospital of former Ji'nan University, the good nurse practitioner of the surgery Zhu Mu of out-patient department of Guangdong People's Hospital and Guangdong Provincial TCM Hospital operating room Li Lan nurse-in-charge to think that existing blood exchange transfusion set does not comprise transfusion needle and drips fast actuator.Its main foundation that does not comprise transfusion needle is: 1. the connected mode between transfusion needle and the existing blood exchange transfusion set not only is flexible connection, and has the transfusion needle product of different model and independent packing to match for medical personnel temporarily; 2. in recent years, new techniques such as transfusion catheter, needleless (transfusion) seal nipple, transfusion three-way cock are rapidly developed and extensive use, even be furnished with transfusion needle in blood exchange transfusion set's the packaging bag, and also can it is discarded; 3. Chinese pair of ShangHai ShuangGe Industry Co., Ltd of Columba livia group (address: No. 1888, HuHang Highway, ShangHai FengPu, exchange: 021-67104888, fax: the packing crates of blood exchange transfusion set's product 021-67104666) is marked with the band pin or not with the printed words of pin, illustrate that this enterprise has two class blood exchange transfusion set products at least, and then can show that transfusion needle is not blood exchange transfusion set's necessary parts; 4. emergency department of Guangdong People's Hospital has used the blood taking needle that a kind of centre is provided with Active Interface in recent years, blood sampling (check) finishes the cannula needle separation is discarded, pipe bolt with Active Interface is socketed on the tube for transfusion end fitting then, need not connect transfusion needle separately just can drip defeated, both reduce the patient suffering, reduced the nurse job amount again; 5. " Chinese practical nursing magazine " (being sponsored by Chinese Medical Association) published the scientific research paper of one piece of exercise question for " can come the novel clinical use of good fortune (needleless seal nipple) " in JIUYUE, 2006 on the 54th page of the 22nd volume version in the 9th the first tenday period of a month phase; " Modern Nursing magazine " published one piece of scientific research paper that exercise question is " application of needleless transfusion system in the child vein retained transfusion " November calendar year 2001 at the 7th volume o. 11th 62-63 page or leaf, shows that all existing blood exchange transfusion set, transfusion device do not comprise transfusion needle.It does not comprise that the foundation of dripping fast actuator is: primary latex tubing transfusion device both had been used for transfusion, also be used for blood transfusion (now adopting now defeated), it is to regulate by the height of regulating transfusion kettle (bottle) to drip speed, the professional had set up metal screw (twin screw) folder formula in succession and had dripped fast actuator (can assemble at any time or remove) on the outer wall of latex tube for transfusion afterwards, on the plastic infusion pipe, set up race folder formula and dripped fast actuator (plastic), made things convenient for nurse's operation to a great extent; But occurred in recent years movablely being connected out that liquid interface (tube for transfusion end fitting) is gone up and the transfusion that has a titration actuator (dripping fast actuator for a kind of adjustable type of transferring the files) prolongs and manages (import) product for clinical use (manufacturer: Irish Abbott Laboratories company limited), can fast regulate the milliliter number that per hour sets exactly according to labelling on the titration actuator and doctor's advice, thoroughly having exempted the nurse is seeing the clock and watch number and drips number and regulate race folder formula back and forth and drip the trouble that fast actuator brings, not only saved trouble but also safety, and existing blood exchange transfusion set, race folder formula on the infusion apparatus product is dripped fast actuator and is often abandoned.Therefore, can think that existing blood exchange transfusion set, transfusion device do not comprise a fast actuator.Certainly, if Patent Office thinks that the present invention lacks necessary parts and lacks essential features in other words, welcome clear and definite (directly) in revisal or notification of examiner's opinion points out that (need not analyze or discuss) lacked certain parts, designer of the present invention will give and respecting fully, and it can be included explanation hereby].
Further, described disposable exempt from the continuous liquid blood exchange transfusion set of aerofluxus include the liquid road that is arranged on extended type dropping funnel top (referring to the tube for transfusion, feed liquor interface of extended type dropping funnel top etc.) or below the liquid road (refer to extended type dropping funnel below tube for transfusion, go out liquid interface etc.) go up a fast actuator that can drip speed for nurse's manual adjustments, drip defeated the adjusting for the patient of public ward and drip the speed use, and then be convenient to nurse's operation.
Further, when described feed liquor interface was " Y " shape feed liquor interface, the wherein arm that is somebody's turn to do " Y " shape feed liquor interface top was provided with a liquid medicine filter and is used for dripping loading liquid, and another root arm is used for the blood transfusion conversion.
Further again, in the time of on the liquid road above described fast actuator is positioned at the extended type dropping funnel, then the liquid road below its (referring to the extended type dropping funnel) is provided with the switch (the fast actuator that drips that contains one-hand operation) that can open and close its (liquid road that refers to extended type dropping funnel below).When described fast actuator be positioned on the liquid road of extended type dropping funnel below and for singlehanded control drip fast actuator the time, then its (referring to the extended type dropping funnel) top the liquid road be provided with the switch that can open and close its (liquid road that refers to extended type dropping funnel top) (contain can single, double manual fast actuator).When described fast actuator is positioned on the liquid road of extended type dropping funnel below and during droplet fast actuator controlled for both hands, then all be provided with the switch (the fast actuator that drips that contains one-hand operation) that can open and close them on the liquid road of above its (referring to the extended type dropping funnel) and below, be used for anti-residual liquid control.
