Description

The anti-liquid residue type of disposable auto-stopping streaming blood exchange transfusion set
Technical field
The present invention relates to a kind of medical disposable transfusion set (note: along with the lifting of scientific and technological progress and cognitive competence, original transfusion device has been divided into transfusion device, blood exchange transfusion set.Syringe has differentiated human body, has made up a prescription, self-destruction, noresidue, for animals ... Deng syringe.Afterwards blood exchange transfusion set differentiates again band pin, needleless, whole blood, component blood ... Deng blood exchange transfusion set; Transfusion device differentiates again lucifuge, portable, intravenous nutrition, titration adjusting, buret type, anti-residual liquid, automatic liquid-stopping, automatic vent, secondary filter ... Deng transfusion device; The differentiation of this medical infusion utensil is promoting again medical skill development conversely.Why technical field of the present invention adopts " disposable transfusion set " and do not adopt " medical drop-infuser tool " is because its technical field has presented obvious differentiating phenomenon), relate in particular to the anti-liquid residue type of a kind of disposable auto-stopping streaming blood exchange transfusion set.
Background technology
One, liquid wasting phenomenon and reason
(1) drip the aerofluxus after tube for transfusion air inlet in defeated process, discharge opeing and the previous infusion bottle of topping up phenomenon (note: for ease of describing again, the present invention represents transfusion bag, transfusion bags with soft bag, with infusion bottle, represent infusion bottle, soft bag) stop dripping and by patient, do not found in time, air can enter Murphy type burette [note: the present invention by its (as: habitual Straight Murphy type burette, the Murphy type burette that offers grafting dosing interface, cone-shaped Murphy type burette etc.) referred to as dropping funnel.By the company's of being referred to as bottle devices such as plug bottle adapters, plug bottle connecting needle (it comprises side-hole needle, inclined-plane pin and is furnished with the airway etc. of air cleaning part).Will be independently blood filter, composition blood filter, is arranged on blood filtration sieve in dropping funnel etc. and is referred to as blood filter.To be arranged on dropping funnel, blood filter, the transfusion catheter at burette top (as: Straight transfusion catheter, the Straight transfusion catheter of being furnished with a switch/fast actuator, Y shape transfusion catheter, the Y shape transfusion catheter of being furnished with a switch/fast actuator, the Y shape transfusion catheter of being furnished with a switch/defeated actuator and soft bag, be furnished with switch/one of them arm of fast actuator and be provided with the Y shape transfusion catheter of liquid medicine filter, offer the L shaped transfusion catheter of grafting dosing interface, the L shaped transfusion catheter of being furnished with a switch/fast actuator, is furnished with liquid medicine filter, the transfusion catheter of switch and traffic pipe etc.) be referred to as dropper, because they are all the transfusion catheters that is positioned at dropping funnel top, therefore title dropper.To be arranged on company's bottle device at dropping funnel, blood filter top, company's bottle device at burette top (containing burette), company's bottle device of dropper upper end (containing dropper) etc. is referred to as feed liquor interface, so-called feed liquor, it is for dropping funnel.Transfusion catheter (as: the Straight transfusion catheter of dropping funnel liquid outlet will be connected to, lower end is connected with the transfusion catheter of short section of elastic tube, offer the transfusion catheter of grafting dosing interface, can make its intracavity bubble, aeroembolism upper row's liquid gas convection current transfusion catheter automatically, lower end is connected with the liquid gas convection current transfusion catheter of short section of elastic tube etc.) be referred to as tube for transfusion.By be arranged on tube for transfusion end habitual joint (as: mammiform joint, cap button joint, moveable cap button joint), transfusion needle, infusion tee cock etc. be referred to as out liquid interface] and transfusion lumen in.Its problem is: 1., when tube for transfusion enters short section of air, nurse is often firmly wrapped in tube for transfusion from bottom to top on finger and makes tube for transfusion become the flat air of upwards extruding in tube for transfusion, sometimes needs the success of repeatable operation ability, very inconvenient while taking power consumption; 2. when tube for transfusion enters long section air, first separated transfusion needle discharges stagnant liquid and air in tube for transfusion, then make tube for transfusion topping up and continue to drip defeated again, not only operation sequence is loaded down with trivial details, easily cause interface and ward to pollute, and often because the discharge of liquid especially repeats to discharge, affect the treatment and cause waste (notes: the symbol "/" in file of the present invention refers to "or").
(2) dripping the stagnant liquid origin cause of formation in transfusion bag, blood exchange transfusion set in defeated process and abandon phenomenon is the trouble preventing due to tube for transfusion air inlet, when adopting transfusion bag, drip when defeated, the most of nurse especially nurse of emergency department is the airway of deliberately not planting, its result can cause the stagnant liquid of generation in transfusion bag, dropping funnel and whole piece tube for transfusion, nurses or be with liquid to pull out next bag liquid of pin/changing-over because patient calls, together with stagnant liquid, residual liquid, abandon in the lump, according to survey, mostly upper and lower at 20 milliliters.Especially the small size transfusion bag of precious liquid, its residual liquid amount is relative with the ratio of setting amount of infusion to be wanted greatly, and this is a unacceptable but problem for inconvenient processing.
(3) drip the discharge opeing after blood back in defeated process and blood coagulation liquid road are stopped up and the phenomenon that punctures again because tube for transfusion air inlet meeting makes the fluid column pressure decreased that shortens, or when patient's changing position causes venous pressure fluctuation, often there is blood back phenomenon, even a little blood back in transfusion needle stalk, if do not find in time in time continuous liquid, normal hyperamization liquid solidification liquid road is stopped up, discharge opeing again, aerofluxus, topping up and puncture, troublesome poeration not only, and can increase patient suffering and cause waste.
(4) drip in defeated process or drip the residual liquid origin cause of formation in infusion bottle in defeated latter stage and abandon phenomenon owing to connecting the inlet of bottle device and be positioned at its tip, thereby can cause the bottleneck of infusing, bottleneck generates residual liquid, according to surveying its residual liquid amount mostly 2 milliliters of left and right, especially valuable residual liquid (for example: the price of current one bottle of 50 milliliters of albumin injection is 600 yuan is often left in the basket, if residual 1 milliliter, its direct losses are exactly 12 yuan), after previous infusion bottle stops dripping or on the same day, drip defeated latter stage [refer to the same day last infusion bottle stop dripping after that time when dripping defeated end, below (containing claims) no longer heavily release] together with the residual liquid of infusion bottle and its intracavity, abandon in the lump, generally nurses can love, but have no way of disposing.In addition, the medical personnel of department of neurology discuss used albumin infusion bottle to other section office often, and residual liquid is spread upon on undergraduate course paralysed patient decubital ulcer skin ulcer face and promotes its healing, and this phenomenon is just enough to show its problem place.
(5) drip stagnant liquid, the residual liquid origin cause of formation in dropping funnel in defeated latter stage, tube for transfusion and abandon phenomenon when 1. descending its pressure that shortens of fluid column equates with venous pressure in dropping funnel drips empty tube for transfusion, tube for transfusion hypomere just can present fluid stagnation phenomenon (note: the liquid holdup phenomenon presenting in tube for transfusion after previous infusion bottle stops dripping, the present invention by it referred to as stagnant liquid; Dripped the liquid holdup phenomenon that present in tube for transfusion defeated latter stage the same day, the present invention by it referred to as residual liquid), its residual liquid amount and venous pressure individual variation, site of puncture and the tube for transfusion hypomere closely related (note: so the so-called tube for transfusion epimere of the present invention refers to that dropping funnel drips that section of empty tube for transfusion that enters air after sky such as bent circuitous degree that wriggles, the so-called tube for transfusion hypomere of the present invention refers to that dropping funnel drips empty rear that section of tube for transfusion that presents stagnant liquid phenomenon, respectively accounts for tube for transfusion length 1/2nd; Not tube for transfusion being divided equally is 2,3,4 ... epimere and hypomere shown in after section; So the present invention's so-called " tube for transfusion epimere " and " tube for transfusion hypomere " are relative, its length is roughly, hereby explanation); Especially precious liquid or children's drip when defeated or primary infusion bottle in liquid residue, not only cause waste, and can affect the treatment; Residual for preventing precious liquid, nurse separately drives the washing pipes such as one bottle of G/NS conventionally, and not only operation sequence is loaded down with trivial details and cause new waste, and very unfavorable to the patient of limit sodium, limit sugar, limit liquid; 2. because some patients were always worries that air can enter human body and feel fear, or at dropping funnel, not yet dripping sky, just to urge nurse be that it pulls out pin; Nurse or because the busy liquid of being with pulls out pin, very common together with the stagnant liquid in dropping funnel, tube for transfusion, phenomenon that residual liquid abandons in the lump.
(6) transfusion bags stop dripping after its intracavity residual liquid abandon phenomenon and compare with infusion bottle, residual liquid amount in transfusion bags can be more more, the residual liquid amount of transfusion bags that according to (weighing) its capacity of surveying is 200 milliliters is mostly upper and lower at 10 milliliters, this is because blood is viscous liquid, can be attached on transfusion bags inwall.In addition, with respect to transfusion bag, transfusion bags wall is thicker, and two walls are difficult for being attached together, and subregion can form the periphery of stagnant liquid dead space and transfusion bags and bag mouth support can make near bag wall its in open configuration, on the same day, drips and generates defeated latter stage due to negative pressure.Drip and to be totally lost completely, when bloodstained transfusion bags is dropped, nurses can love generally, but have no way of disposing.Lose blood especially greatly, the patients with transfusion of major operation is when more, its wasting phenomenon is more obvious.
< < nurse studies magazine > > and in the 11st page of the 13rd the 1st phase of phase volume in 1998, has delivered one piece and be entitled as the paper of " experimentation of Eliminating Micro-air into Vein during Venous Transfusion "; The paper that < < Quotation Analysis > > (being sponsored by Ministry of Public Health) has delivered one piece and be entitled as " discharge method of long section air under infusion process Murphy type burette " in the 54th page of the 19th the 3rd phase of volume of March in 2003 can show the above-mentioned defect place of traditional infusion device.
Two, correlation technique defect
Anti-liquid residue formula transfusion device (patent No.: ZL00239693.9, the day for announcing: calendar year 2001 JIUYUE 26 days) defect be: 1. can not rinse and wash and splash into human body (call in the following text and can not rinse bottle and splash into human body) the infusion bottle chamber of precious liquid; 2. critical patient drips defeated more than ten bottles of liquid every day mostly continuously, because dropping funnel liquid inlet and outlet respectively has a check-valves, in dripping empty tube for transfusion, dropping funnel during air inlet, even if short section of air can not be gone up row, can only adopt the method for separated transfusion needle to discharge stagnant liquid and the air in transfusion lumen; Due to the discharge of stagnant liquid or repeatedly discharge, can affect the treatment and cause waste on the contrary, therefore think that it is not suitable for dripping continuously defeated use; 3. previous infusion bottle drip empty after air can enter and in tube for transfusion, make the fluid column pressure that shortens diminish, often cause blood back, even the obstruction of blood coagulation liquid road, discharge opeing again, aerofluxus, topping up and puncture also likely occur a little blood back in transfusion needle stalk, not only bother, and can waste; 4. in season in midwinter, when ice-cold liquid enters behind heating installation ward, be dissolved in hydrone gap when gases are heated, they expand (especially the heated liquid speed in the flowing fluid ratio infusion bottle in tube for transfusion is fast) to separate out and form the bubble that is attached to tube for transfusion inwall, the very difficult discharge that made progress of effect due to check-valves, when a large amount of transfusion gas is cumulative, must be opened to liquid interface discharge opeing, aerofluxus, not only bother, and can waste; 5. before transfusion, first company's bottle device of transfusion device is injected in inverted mouth of infusion bottle, then close tube for transfusion pinching dropping funnel, the air of its intracavity is got in infusion bottle and made a little rising of infusion bottle internal pressure, to toward transfusion device internal-filling liquid, then carry out venipuncture.Because dropping funnel inlet is provided with check-valves, be difficult to the air in dropping funnel to get in infusion bottle, defeated operation (referring to drip defeated preparation) is dripped in impact.
Disposable multifunction safe transfusion system (patent No.: 02280389.0, the day for announcing: defect on October 29th, 2003) must be from microscopic techniques and the feasibility understanding that gets on: 1. can not rinse bottle and splash into human body, 2. sandstorm, haze weather have become the topic on current compatriots' the tip of the tongue, and on dosing inducing QI three ports 5, do not configure air cleaning part, be a kind of air guide port that exposes formula, after uncapping, being suspended in virus in atmosphere, pathogenic bacteria, dust, small insect etc. has the danger that enters liquid road, 3. on dropping funnel liquid inlet and outlet, respectively have a check-valves, the defect of the problem that it causes and anti-liquid residue formula transfusion device is identical, no longer repeats, 4. (referring to Figure of description 1,7,12) dosing inducing QI three ports 5 are positioned at dropping funnel top, it can cause three kinds of problems: one, can only drip and just can uncap defeated latter stage on the same day, otherwise can cause tube for transfusion air inlet and can affect metering and the prompting functions such as whether liquid road unobstructed of dropping funnel, they are two years old, nurse must wait liquid in dropping funnel and tube for transfusion epimere and naturally enter human body and could do further to dispose, because some disease (as heart failure) be can not input too fast, use syringe to inject 5 milliliters, 10 milliliters medicinal liquids and also can set a time, if inject too fast or cause problem, they are three years old, can take and waste nurse's time, nurse be hospital nurse be also medical worker, working is just as fighting, its work characteristics is, must be that doctor, patient are at someone's beck and call can not delay or delay, and especially runs into that multidigit patient calls out simultaneously, weather fusion, accident or natural disaster patient be when uprush, and nurses' pressure of often attending to one thing and lose sight of another is very large, therefore, how facilitating nurse to be conducive to patient, is a problem that needs are pondered deeply for nurse saves a little time, 5. from the terminal phase of intravenous injection device for auto closing valve of its technical characterictic of design principle, be rational, but successively through the San Jian factory model test of nearly a year, its terminal phase of intravenous injection device for auto closing valve can not be realized the Expected Results of closing liquid road, its reason may be with to drip when defeated the slow negative pressure generative process of liquid level downstream rate long (it be rely on liquid level slowly descending and generate negative pressure) negative pressure value float low and (referring to Figure of description 7) cone-shaped float-type terminal phase of intravenous injection device for auto closing valve little relevant from heavy and light and pressure, in addition, compare with pristine glass dropping funnel, the dropping funnel of existing transfusion device is made by translucent soft material, be subject to a little the caving inward of suction function to become flat and offset a part of negative pressure, and then can reduce negative pressure value and affect and close effect, 6. membrane type terminal phase of intravenous injection device for auto closing valve is positioned at dropping funnel top, before transfusion, the pinching dropping funnel institute relatively high negative pressure of moment generation can make membrane type terminal phase of intravenous injection device for auto closing valve in closed condition, inconvenience is toward transfusion device internal-filling liquid, affect transfusion operation, and become, abandon this Patent right six factors.At least the design people did not expect above problem originally, and not yet found pertinent literature and product at present, otherwise did not just have the application yet.
Weihai prestige is high in recent years, Wuhan Gao Xun, many enterprises' SEPARATE APPLICATION such as Jiangxi HTC a kind of identical automatic-exhaust transfusion device, they are that the outer wall center that is referred to as the admission chamber of precision liquid medicine filter (shape, as wrist-watch, is inside established two chambeies) at tube for transfusion hypomere has been driven one or the air vent of being furnished with seal cover and formed.Using method is: 1. in previous infusion bottle drips empty defeated pipe, during air inlet and while not establishing seal cover on air vent, can directly continue liquid; 2. in previous infusion bottle drips empty tube for transfusion, during air inlet and while being furnished with seal cover on air vent, should first uncap and continue again liquid.They are to utilize the bidirection press of the interior aeroembolism of tube for transfusion top fluid column pressure and venous pressure that gas is extruded to air vent.Its exhaust mode divides two kinds of the aerofluxuss of uncapping when opening wide aerofluxus and needing.Its defect is: 1. can not rinse bottle and splash into human body; 2. dripping defeated latter stage tube for transfusion hypomere the same day has residual liquid phenomenon, and its residual liquid amount is closely related with the factors such as size, shape that are referred to as precision liquid medicine filter, according to the residual liquid amount of surveying certain enterprise product 8 milliliters of left and right; 3. previous infusion bottle drip empty after air can enter and in tube for transfusion, make the fluid column pressure that shortens diminish, have the blood back He Ye road of generation to stop up risk, or discharge opeing again, aerofluxus, topping up and puncture; According to three nurse's introductions of Nanning City the second the People's Hospital diabetes section, compare with traditional infusion device, automatic-exhaust transfusion device (product as high in Weihai prestige, even if dropping funnel does not drip sky) more easily there is blood back (mostly when patient's changing position), its reason may be relevant with a little release of pressure effect of air vent (just as the air vent of high-pressure pot cover); 4. its exhaust mode is still open aerofluxus in any case, the position difference of just opening; Because air vent is positioned at tube for transfusion hypomere, when wounds oozing of blood, open sore part pyorrhea, gatism, sneeze, blows one's nose, and cough is spat, and the water of the choking food of choking, when nausea and vomiting or on one's sick bed defecation, has through air vent contaminated liquid transportation work style danger; As everyone knows, the microorganism such as antibacterial, virus is ubiquitous all-pervasive, since gas can be discharged from air vent, the pathogenic microorganism such as antibacterial, virus is also likely invaded from air vent, even 1/10000000th probability, also avoid as far as possible, once all very passive or engender tension relations of the tripartite of Yi,Huan, factory that go wrong, the event that makes medical personnel's homicide case for a little minor issue happens occasionally; Transfusion is input after all, airtight higher than open safety, even if urethral catheterization and drain also can be emphasized the problem of a seal, can not make it always open wide; It is how important to safety that the inside and outside section general " closed drainage bottle " that medical worker was familiar with is just enough to show airtight; 5. its air vent sweet taste that especially air vent of open type appears, fishy smell (blood product) can noly be caused mosquitos and flies, Formica fusca, jumping and disturbed etc. and to need the time to observe; While being 6. unworthy of seal cover on air vent, easily by " automatically " two words, misled, because air vent is positioned at tube for transfusion hypomere, once limbs of patient kills air vent, air has the danger that enters human body; While being furnished with seal cover on air vent, must opening the gas Natural excrements such as seal cover and cover back, name day automatically also must be manual, not only bothers, and can waste nurse's time.
The patent No. is that 201120265273.0 the disposable defect of exempting from the continuous liquid transfusion device of aerofluxus is: 1. can not rinse bottle and splash into human body; 2. after last bottle fluid drips sky, air can enter tube for transfusion epimere intracavity the fluid column pressure that shortens is diminished, and has the risk that causes blood back Ji Ye road to be stopped up, and become, abandons this Patent right two main causes.
The patent No. is the disposable use automatic liquid-stopping transfusion apparatus (producer: Europe, Zhejiang health care spirit armarium company limited of ZL200320131818.4, phone: 0576-85289098) float valve of product is positioned at dropping funnel below, can not only prevent from bothering due to tube for transfusion air inlet, and fluid column high pressure large can effectively anti-return blood and blood coagulation due to liquid road stop up, especially pollute and occupational infection on the environment ,Ye road that the continuous liquid modes such as open aerofluxus or open discharge opeing aerofluxus that can prevent may cause, and has Partial Hospitals emergency department and adopted this product for alleviating operating pressure.Yet it has but occurred another more distinct issues after having solved a problem, that dripped and can cause defeated latter stage generating residual liquid in whole piece tube for transfusion on the same day exactly, according to measuring its residual liquid amount in kind, was 10 milliliters; Especially primary infusion bottle or infantile infusion, its residual liquid amount is relatively large with the ratio of setting amount of infusion.For example: if the same day, last infusion bottle was 50 milliliters, its direct losses are exactly 1/5th.Patient's loading every day amount is that doctor calculates according to factors such as weight in patients, the state of an illness, ages; Therefore, nursing college has strict demand to Nurse training, when transfusion device internal-filling liquid and aerofluxus are gone in transfusion (referring to the preparation of infusing), just seen that transfusion needle point has overflow of drug fluid should immediately close liquid road, the medicinal liquid of discharging can not surpass 3 (water dropper of national technical standard is 15 of every milliliter of medicinal liquids), toward once success of the operation of transfusion device internal-filling liquid, otherwise examine defective, must the qualified permission graduation of make-up examination.Therefore have more hospital especially the Affiliated Hospital of emphasis medical college and school mostly decline this product.Even there is the patient who is expert to refuse to use this product.The deputy director of National Development and Reform Committee Zhu Zhixin has disclosed surprising data in the early time, and within 2010, China infuses 8 bottles per capita ... (seeing Guangzhou Daily B24 on January 15th, 2011).By every 2 bottle liquid medicines join 1 transfusion device (this be consider critical patient mostly drip every day defeated many bottles and most of outpatient service and basic medical unit and partial hospitalization patient are mostly dripped defeated 1 bottle at every turn) every residual 10 milliliters of year of transfusion device per capita (4 transfusion device) waste 40 milliliters of medicinal liquids (wastes due to the discharge opeing after stifled containing liquid road due to aerofluxus, discharge opeing and blood back after tube for transfusion air inlet in stagnant liquid, residual liquid and infusion process in transfusion bag, infusion bottle and again puncture etc.) estimation, it will be a huge numeral, and certainly the medicinal liquid of its direct losses is surprising equally.Outside anthropic factor (as patient lacks correct health idea requirement garter, going after profit or gain property of public hospital, private hospital commercial activity etc.), closely related with transfusion system structure defect.This transfusion device defect is also: can not rinse bottle and input human body.Along with the medical support system is perfect, universal and development, the people who beats garter also can be increasing, and its wasting phenomenon also can be on the rise.
Note: 1. blood filter housing is made and facilitated nurse to observe inner case and pinching by translucent flexible material, the area of blood filter housing and drainage screen and mesh are all larger, to guarantee that various erythrocyte can break by unlikely damage, can prevent from the erythrocyte plugging fluid road of fat granule and gathering simultaneously or enter patient pulmonary through the right heart causing lung infraction; Drip blood filter when defeated and substantially keep hollow state, point out liquid Lu Buchang when liquid level rises in string bag, nurse can gently squeeze erythrocyte that string bag makes to assemble across housing and scatter and make liquid Lu Zaitong; Blood filter is mostly positioned at tube for transfusion top.And the fine and close housing of the filter membrane of liquid medicine filter is relatively little and made in case limbs crimp causes filter membrane and dislocates by hard material, liquid medicine filter is mostly positioned at especially end of tube for transfusion hypomere, and dripping must emptying air when defeated.Although transfusion device and blood exchange transfusion set's a defeated principle is similar, but there is notable difference in the structure of the two, purposes, using method, the utensil that belongs to different field, moreover not yet find at present the anti-liquid residue type of the disposable auto-stopping streaming blood exchange transfusion set who duplicates mutually with the application, the reasons such as wasting phenomenon a lot of based on the different utensil of principle same use and the transfusion of blood transfusion ratio is more outstanding, for impelling the solution of this problem, therefore it is applied for separately; Though 2. at present do not find automatic liquid-stopping blood exchange transfusion set, float valve is prior art, maybe can be considered to easily expect, describes therefore the application places it in claim 1 preorder.
Summary of the invention
The present invention has benefited from once going out running in way the clear soil mud stone of landslide traffic after being obstructed, bore the tree end, climb rubble and the multiple processing mode such as detour and be inspired.The object of the invention is: 1. provide a kind of not only can automatic flow-stop, and can prevent that tube for transfusion epimere from generating the blood exchange transfusion set of residual liquid; 2. facilitate the anti-residual liquid operation of nurse; 3. can avoid the air-guide type that exposes formula may cause the pollution of Ye road.The present invention also aims to: while 1. dripping defeated precious liquid, the residual liquid in infusion bottle, tube for transfusion all can be inputted to human body; 2. the quick infusion that can pressurize blood transfusion rescue patient; 3. can will on bubble possible in tube for transfusion, aeroembolism, arrange, for the patient in season in midwinter, drip continuously defeated; 4. drip before defeated and air in dropping funnel can be got in infusion bottle and make its intrinsic pressure a little rising, be conducive to blood exchange transfusion set's topping up, avoid impact to drip a defeated operation (referring to drip defeated preparation).
The present invention is by providing the anti-liquid residue type of a kind of disposable auto-stopping streaming blood exchange transfusion set to solve above-mentioned technical problem.Comprise habitual feed liquor interface, blood filter, dropping funnel, float valve, tube for transfusion, drip fast actuator and go out liquid interface, feature is: it by be arranged on tube for transfusion top liquid Lu Shangneng on the same day, drip defeated latter stage the atmosphere having purified in from infusion bottle is imported in transfusion lumen from top to bottom/can drip and defeated latter stage ambient atmosphere be purified to the enclosed air guide mechanism that also it can be imported in transfusion lumen from top to bottom and formed on the same day, or by be arranged on feed liquor interface not only can liquid storage and also can be for nurse's manual pump liquid so can stop at the infusion bottle of precious liquid to drip after it is rinsed to the imitative gallbladder formula of washing and splash into human body rinse a bottle eropper and formed, or by be arranged on tube for transfusion top liquid Lu Shangneng on the same day, drip defeated latter stage the atmosphere having purified in from infusion bottle is imported from top to bottom in transfusion lumen/can the same day drip defeated latter stage ambient atmosphere is purified and it can be imported to the enclosed air guide mechanism in transfusion lumen from top to bottom and be arranged on feed liquor interface not only can liquid storage and also can confession nurse's manual pump liquid so can stop at the infusion bottle of precious liquid droplet after it is rinsed to the imitative gallbladder formula of washing and splash into human body rinse a bottle eropper and formed.Described enclosed air guide mechanism be a kind ofly can open in advance for nurse, with closing/open in advance/after the atmospheric pressure conduction mechanism that opens; So-called " opening in advance " refers to that described enclosed air guide mechanism can (in advance) unlatching Shi Ye road be unimpeded conveniently in continued access last infusion bottle on the same day for nurse; So-called " with closing " refers to when conditions of patients sudden change need add drop of liquid that described enclosed air guide mechanism can be closed conveniently and then can make the spool of float valve return to automatic open close liquid line state for nurse temporarily and continues droplet defeated; It is manually opened and then can atmospheric pressure (containing from the atmospheric pressure in infusion bottle, two kinds of situations of external atmospheric pressure) be imported in transfusion lumen from top to bottom that so-called " opening afterwards " refers to that described enclosed air guide mechanism at least can drip defeated latter stage on the same day for nurse; So-called " enclosed air guide mechanism ", it is for exposing the air guide port of formula, but not directly ambient atmosphere is imported to mechanism in transfusion lumen [note: five middle and high grade of nurse practitioners that the application has specially interviewed four, Guangzhou provinces, City Hospitals with regard to essential features problem think that blood exchange transfusion set does not comprise transfusion needle.It is according to being: 1. the connected mode between transfusion needle and blood exchange transfusion set is not only for being flexibly connected, and have different model and separately the product of packing supply nurse to match; 2. the new technique such as transfusion catheter, needleless seal nipple, infusion tee cock is in recent years rapidly developed and extensive use, even if be furnished with transfusion needle in blood exchange transfusion set's packaging bag, also can be discarded; 3. < < China Quotation Analysis > > (being sponsored by Chinese Medical Association) has published one piece of paper that exercise question is " can carry out the novel clinical use of good fortune (needleless seal nipple) " in JIUYUE, 2006 in the 54th page of the 22nd volume version in the 9th the first tenday period of a month phase;

The specific embodiment
Embodiment 1:
As shown in Figure 1, 2, feed liquor interface consists of side-hole needle 1, dropper 2 and the purification type airway 3 (practise claim exhaustor) of being furnished with air cleaning part 5.Also side-hole needle 1 directly can be set to blood filter 4 tops and the common formation feed liquor of purification type airway 3 interface.Use soft bag to drip the defeated purification type airway 3 of also should planting and reduce stagnant liquid, residual liquid as far as possible.Be furnished with the tube for transfusion that drips fast actuator 11 by habitually practise transfusion catheter 12 and short section of elastic tube 14 (its effect is: 1. during venipuncture pinching it can rebound and can impel blood back to confirm whether success of puncture; 2. can malleation pull out pin, that is pin is pulled out on pinching limit, limit in case ecchymoma or pin mouth oozing of blood) form.Take out mammiform (taper shape) joint 13 of liquid interface for the socket of transfusion pintle.Float valve 8 is positioned at water dropper 6 belows (Fig. 1 is dropping funnel below), locating part 7 energy anti-spool Shang Duye roads [note: it (is that float valve and dropping funnel match well that the rear visual float valve of omission locating part 7 is positioned at dropping funnel bottom, dropping funnel bottom tube wall doubles as float valve housing, spool is positioned at dropping funnel bottom, also can be described as float valve housing and double as dropping funnel bottom tube wall), below no longer heavily release].The groove of spool bottom centre is embedded with flexible sealed piece.Between vertical guiding drain fin 9 (being generally more than three) on spool sidewall and float valve sidewall, be provided with fit clearance, keep making under spool free floating prerequisite it always in vertical state to guarantee to close effect.Compare with the float of Multifunctional safety transfusion system, the heavier pressure of this spool is large and be embedded with flexible sealed piece, and practice shows conscientiously to close liquid road.Enclosed air guide mechanism is be a kind ofly opened on float valve liquid outlet and be furnished with air cleaning part (being located at the air cleaning film of its intracavity) and opening and closing element (seal cover) can open formula purification type air guide port 10 for the lower postpone of opening after nurse, drip open that seal cover (i.e. so-called can opening for after nurse) just can purify ambient atmosphere defeated latter stage also can be by it in float valve liquid outlet and tube for transfusion upper end importing transfusion lumen, and then can prevent that tube for transfusion epimere from generating residual liquid, when observing transfusion liquid in pipe, stop pulling out transfusion needle when descending and finish transfusion on the same day.The tracheotomy ventilation of its principle after just as larynx tumor airway obstruction.Its weak point is: nurse need wait until that tube for transfusion epimere residual liquid automatically enters human body and could do further to dispose, comparatively time-consuming, therefore classify the inferior embodiment that selects as.As shown in Figure 3, when float valve is positioned at (dropping funnel 18 tops, water dropper 6 tops, below no longer heavily release) time, can by after open formula purification type air guide port and be set to dropping funnel 18 tops (upper 1/3rd, separately mapping) or on float valve liquid outlet, and can be renamed as postpone and opened formula purification type air guide port 16.Another when float valve housing is with dropping funnel tube wall disjunctor when (still as shown in Figure 1), need by after open formula purification type air guide port and be set to dropping funnel top (separately not mapping) and also can be belonged to the category that formula purification type air guide port is opened in upper postpone.Drip and to open that opening and closing element (switch 17) just can purify ambient atmosphere defeated latter stage and it can be imported in transfusion lumen via dropping funnel inner chamber and tube for transfusion upper end, in case dropping funnel 18 and tube for transfusion epimere generation residual liquid.The float valve inlet 15 energy anti-spool Shang Duye roads of angle, therefore can be regarded as locating part.Drip defeated front float valve, dropping funnel the pinching dropping funnel be first inverted its intracavity air is got in infusion bottle and made its intrinsic pressure a little rising, then toward blood exchange transfusion set's internal-filling liquid.Compare with the membrane type terminal phase of intravenous injection device for auto closing valve 3 of Multifunctional safety transfusion system, this dropping funnel of pinching institute generates relatively high negative pressure moment can not make float valve in closed condition, favourable blood exchange transfusion set's topping up does not affect and drips defeated operation (note: shape, shift in position and the Name Change thereof of the connected mode of following examples, using method, functional effect and enclosed air guide mechanism etc. exist identical situation, are not described in detail).
Embodiment 2:
As shown in Figure 4, feed liquor interface 20 drips the dropper of fast actuator 11 and indicates burette 23 formations that scale is provided with suspender 19 by being furnished with the plug bottle adapter 22 of purification type air guide port 21 (practise and claim air vent) and being furnished with.Drip fast actuator 11 and adopt liquid measure for controlling.Dropping funnel 28 intracavity are provided with blood filter 29.Water dropper (microdroplet water dropper) 27 drips defeated for children's.Float valve 25 is positioned at water dropper 27 tops.Feeler sample locating part 24 on spool can anti-spool Shang Duye road.Enclosed air guide mechanism is for being arranged on float valve liquid outlet and float valve sidewall and being furnished with switch 17 (slide fastener) and can opening in advance for nurse, with close conversion liquid road on put controllable type bypass type airway 26, in continued access last infusion bottle on the same day, being opened conveniently (i.e. so-called can opening in advance for nurse) can (be just the atmosphere purifying through purification type air guide port 21 by the atmosphere having purified in from infusion bottle in a defeated latter stage, be designated hereinafter simply as the atmosphere in infusion bottle) from float valve 25 liquid roads, top (feed liquor interface 20), float valve 25, dropping funnel 28 inner chambers (containing blood filter 29) and tube for transfusion upper end import in transfusion lumen, just can prevent that dropping funnel 28 and tube for transfusion epimere from generating residual liquid.When conditions of patients sudden change need add drop of liquid temporarily, can close conveniently to close and put controllable type bypass type airway 26 and make spool return to automatic open close liquid line state (so-called can confession nurse with closing).When above putting the upper end of controllable type bypass type airway, change (separately mapping) while being located on feed liquor interface 20, rename as and put around valve controllable type bypass type airway, pre-breakdown close 17 just can drip defeated latter stage by the atmosphere from infusion bottle above float valve in liquid road (feed liquor interface 20), dropping funnel 28 inner chambers (containing blood filter 29) and tube for transfusion upper end importing transfusion lumen.Its principle is just as the navigation channel of Three Gorges Dam side.Compare with the exposure formula air guide port 5 of Multifunctional safety transfusion system, save time, airtight, nimble, safety.If by put controllable type bypass type airway 26 lower end change and be located on dropping funnel 28, surely can affect dropping funnel function; Therefore can only after open, drip and in dropping funnel, also have liquid a defeated latter stage, nurse need wait until that dropping funnel and emptying could the work of tube for transfusion epimere further dispose, and can waste nurse's time, therefore classify time time choosing (inferior choose inferior selects) embodiment as.Manual pressurization pump can form for pressurized capsule (ball) 34 and the switch on its upper and lower liquid road 17 of nurse's extrusion pump liquid by being arranged on pars infrasegmentalis on tube for transfusion (refer under epimere 1/3rd).First close pressurized capsule 34 liquid roads, top and gently pinch again pressurized capsule 34 and residual liquid input human body in tube for transfusion can be closed to pressurized capsule 34 liquid roads, below with blood return prevention immediately when observing when residual liquid all enters human body, then pull out transfusion needle and finish transfusion on the same day.Pressurized capsule 34 is positioned at pars infrasegmentalis reason on tube for transfusion, and it is empty dripping defeated latter stage its inner chamber, and input residual liquid is comparatively convenient, save time, safety.If the position of pressurized capsule is too high is unfavorable for operation, this is to be the liquid gas mobility status in infusion needle guide tube because nurse's eyes are dig-inned during input residual liquid.If pressurized capsule is set to tube for transfusion hypomere, must alternately open and close pressurized capsule 34 upper and lower Ye roads and repeat pinching pressurized capsule 34 and residual liquid could be inputted to human body, this 34 is full (also having residual liquid) because of dripping defeated latter stage pressurized capsule, after must pressurized capsule is emptying, residual liquid all could be inputted to human body, comparatively time-consuming and dangerous, because some patient be can not input too fast, if control bad or cause problem.The volume of pressurized capsule is advisable to be a bit larger tham tube for transfusion hypomere volume, because its intraluminal fluid, gas all can not be discharged during pinching pressurized capsule.Slightly little pressurized capsule also can adopt, and during input residual liquid, repetitive operation is once above is.If specializing in the patient in season in midwinter drips defeated, also pressurized capsule can be set to especially pars infrasegmentalis under tube for transfusion (refer under hypomere 1/3rd) of tube for transfusion hypomere any part, first close liquid road, pressurized capsule below again pinching pressurized capsule 34 can upwards go out possible bubble in tube for transfusion; During input residual liquid, repetitive operation is once or once.Pressurized capsule 34 tops are provided with drips a fast actuator 35 (for the import adjustable type of transferring the files drips fast actuator, its upper and lower can relatively rotate and regulate as stone mill type, screws and can be adjusted to a maximum in, is minimal to and closes, domestic existing similar products).Take out the moveable cap button joint 32 of liquid interface, its cap is buckled 31 (nuts) and can not only as horizontal direction, be relatively rotated around the vertical pivot of mammiform joint 30, and can slide up and down along that outer wall of mammiform joint 30 inlets 33, its positive effect is: can not only spin with the spiral shell button-type pintle of transfusion needle in case accidental, and can be for that infundibulate pintle socket with disjunctor protecting cover.As shown in Figure 5, float valve is positioned at water dropper 27 (dropping funnel 36) below, and blood filter 37 is positioned at dropping funnel 36 intracavity.Enclosed air guide mechanism be arranged on float valve liquid outlet and dropping funnel 36 tube walls and be furnished with switch 38 can for nurse open in advance, with close conversion liquid road underlying around valve controllable type bypass type airway 39; It and dropping funnel 36 form U pipe relation, do not affect dropping funnel function.Pre-breakdown close 38 just can drip defeated latter stage by the atmosphere from infusion bottle above water dropper 27 in liquid road (feed liquor interface 20), dropping funnel 36 inner chambers (containing blood filter 37) and tube for transfusion upper end importing transfusion lumen.In like manner, when underlying changes (separately mapping) while being located on float valve sidewall around the upper end of valve controllable type bypass type airway 39, rename as underlying controllable type bypass type airway, open it in advance and just can the atmosphere from infusion bottle liquid road (feed liquor interface 20), dropping funnel 36, float valve inner chamber and tube for transfusion upper end above water dropper 27 be imported in transfusion lumen in a defeated latter stage.Be understood that, if underlying is changed and is set on feed liquor interface 20 around the upper end of valve controllable type bypass type airway 39, surely can affect dropping funnel function, thus it can only after open, therefore classify as time, time select embodiment.Certainly, also can on burette 23 intracavity or dropper, blood filter be set, and then can omit blood filter 29,37.Youngster, with the reason that float valve, enclosed air guide mechanism and Manual pressurization pump be even more important is set on buret type blood exchange transfusion set, be: 1. can prevent due to tube for transfusion air inlet and blood back that liquid road is stopped up, because of the tiny cooperation difficulty of child vein, then puncture trouble comparatively; 2. infantile infusion total amount is few, and residual liquid amount is relatively large with the ratio of setting amount of infusion.In addition, when pressurized capsule 34 tops are provided with while dripping fast actuator, can omit the switch 17 of its top, this is also to have the function of closing liquid road because drip a fast actuator.But when this kind fast actuator 35 is positioned on pressurized capsule 34 liquid roads, below, preferably retain the switch 17 on pressurized capsule 34 liquid roads, below, this is to need both hands to coordinate because close a fast actuator 35, not too convenient.
Embodiment 3:
As shown in Figure 6, its feed liquor interface consists of two plug bottle adapters 40 and dropper (be provided with liquid medicine filter 41 and drip the Y shape transfusion catheter of fast actuator 11), for tall person nurse, regulates and drips speed, transfusion and blood transfusion conversion and anti-residual liquid and control.Dropping funnel intracavity is provided with blood filter 47.Cap button joint 48 with the difference of moveable cap button joint 32 is: it is to slide up and down along that outer wall of mammiform joint inlet that the cap of cap button joint 48 is buckled.Float valve is positioned at water dropper 6 tops.Enclosed air guide mechanism is to put on a kind of to open in advance formula float valve, and it consists of deformable float valve housing (made and can bending be out of shape by medical flexible material) and spool.Spool consists of the sleeve 44 and the drain pipe 45 that have delivery hole 43 and be embedded with flexible sealed piece 42.Flexible sealed piece 42 and/or sleeve 44 are made by light material (referring to that proportion is less than water).Drain pipe 45 is made by hard brittle material, its stage casing can be broken disconnected across deformable float valve housing smoothly for nurse near the horizontal cut 46 (just as the cut on water for injection Ampoule neck) of deformable float valve housing intracavity bottom in continued access last infusion bottle on the same day, so-called to make it displacement Shi Ye road for nurse's equalizing valve core unimpeded, and then can drip defeated latter stage by the atmosphere from infusion bottle liquid road (feed liquor interface), float valve (above put and open in advance formula float valve), dropping funnel inner chamber (containing blood filter 47) and tube for transfusion upper end importing tube for transfusion 50 intracavity above float valve.Its principle is removed and is blocked just as excision intestinal cancer.Manual pressurization pump forms by being positioned at the pressurized capsule (pipe) 49 of pars infrasegmentalis under pars infrasegmentalis on tube for transfusion 50 or tube for transfusion and the fast actuator 11 that drips on its upper and lower liquid road.First close pressurized capsule top and drip fast actuator 11 and gently squeeze again pressurized capsule 49 and then residual liquid input human body in tube for transfusion can be closed to pressurized capsule 49 belows and dripped fast actuator 11 with blood return prevention, then pull out transfusion needle and finish the same day and drip defeated.Separately need a problem of prompting to be, drive the roller that fast actuator 11 is dripped in pressurized capsule 49 belows can make liquid gas in infusion needle guide tube move down approximately 4 centimeters downwards, thereby should retain appropriate amount of fluid when pinching pressurized capsule 49 input residual liquid, in case close while dripping fast actuator 11, the air of its below can be pressed into human body, therefore must carry out strict training and examination to nurse, comparatively trouble.If be arranged on that section of tube for transfusion of pressurized capsule 49 belows dripping after fast actuator 11 is inverted, when closing it, can cause blood back, therefore think that pressurized capsule 49 belows are the most suitable with such cutoff switch such as chuck, slide fastener.As shown in Figure 7, the blood filter 52 of dropping funnel 51 intracavity doubles as locating part.When in advance the open formula float valve identical or similar with Fig. 6 is positioned at water dropper 6 belows, [it comprises and is positioned at dropping funnel below (separately mapping) or is positioned at two kinds of dropping funnel bottoms set-up mode, Fig. 7 is dropping funnel 51 bottoms, be that spool is positioned at dropping funnel bottom, drain pipe activity is inserted in dropping funnel liquid outlet, dropping funnel bottom tube wall doubles as float valve housing] time, rename as underlying and open in advance formula float valve 53, continued access in last infusion bottle, whipped the same day bending " dropping funnel " 51 bottoms make drain pipe disconnect (dislocation) just can open spool, so-called can confession nurse equalizing valve core to make it displacement Shi Ye road unimpeded, and then can drip defeated latter stage by the atmosphere from infusion bottle liquid road (being feed liquor interface) above water dropper 6, dropping funnel 51 (containing blood filter 52), float
