Description

Disposable auto-stopping streaming liquidproof Residual-type transfusion device
Technical field
The present invention relates to a kind of medical disposable transfusion device, more particularly to a kind of disposable auto-stopping streaming liquidproof are residual Stay type transfusion device.
Background technology
First, liquid waste phenomenon and reason
(1) exhaust in infusion process after woven hose air inlet, discharge opeing and the previous infusion bottle of topping up phenomenon stops dripping and not having again Have and found in time by patient, air can enter Murphy type burette [note:The present invention by it (such as:Usual Straight cyclopentadienyl Fei Shi drops Murphy type burette, cone-shaped Murphy type burette for manage, offering grafting dosing interface etc.) it is referred to as dropping funnel.By plug bottle connector, The company's of being referred to as bottle devices such as plug bottle connection pin (it includes side-hole needle, inclined-plane pin and airway tube equipped with air cleaning part etc.).It will set Put transfusion catheter at the top of dropping funnel, buret (such as:Straight transfusion catheter, the Straight equipped with the fast adjuster of switch/drop is defeated Fluid catheter, Y shape transfusion catheter, the Y shape transfusion catheter equipped with the fast adjuster of switch/drop, the Y shape transfusion equipped with infusion bag and switch Conduit, the L-shaped transfusion catheter provided with grafting dosing interface, L-shaped transfusion catheter equipped with the fast adjuster of switch/drop etc.) it is referred to as Dropper, because they are all to be located at the transfusion catheter above dropping funnel, therefore claims dropper.By the company being arranged at the top of dropping funnel bottle device, drop Company's bottle device (contain buret) at the top of fixed tube, company's bottle device (containing dropper) of dropper upper end etc. is referred to as into liquid interface, it is so-called enter Liquid is for dropping funnel.The transfusion catheter of dropping funnel liquid outlet will be connected to (such as:Straight transfusion catheter, lower end is connected with The Straight transfusion catheter of short section elastic tube, the transfusion catheter provided with grafting dosing interface can make its intracavitary bubble, aeroembolism automatic The liquid gas convection current transfusion catheter of upper row, lower end is connected with liquid gas convection current transfusion catheter of short section elastic tube etc.) it is referred to as woven hose. The usual joint of transfusion pipe end will be arranged on (such as:Mammiform joint, cap button joint, moveable cap button joint), transfusion needle, Infusion tee cock etc. is referred to as out liquid interface] and transfusion lumen in.Its problem is:1. when woven hose enters short section air, Woven hose is often firmly wrapped on finger by nurse from bottom to top makes the deflated upward extrusion transfusion inner air tube of woven hose, needs sometimes Operation could succeed repeatedly, be inconvenient during expense power consumption;2. when woven hose enters long section air, transfusion needle must first be separated outside Discharge woven hose in stagnant liquid and air, then make woven hose again topping up and continue drop it is defeated, not only operation sequence is cumbersome, takes power consumption When, easily cause interface and ward pollution, and often because the discharge of liquid especially repeat discharge and affect the treatment and caused by waste (note:Symbol "/" in file of the present invention refers to "or").
(2) infusion bag in infusion process, the stagnant liquid origin cause of formation in transfusion device and phenomenon is abandoned for caused by preventing woven hose air inlet Trouble, when using infusion bag drop it is defeated when, the nurse of most of nurse especially emergency department is deliberately not plant airway tube, its result Infusion bag can be caused, the stagnant liquid of generation in dropping funnel and whole piece woven hose, nurses or because patient calls and it is next to pull out pin/changing-over with liquid Bag liquid, is abandoned in the lump together with stagnant liquid, raffinate, mostly upper and lower at 20 milliliters according to survey.The especially small size transfusion of precious liquid Bag, its raffinate amount is relative with the ratio of setting amount of infusion to be wanted greatly, and this is that one unacceptable but the problem of inconvenient processing.
(3) blood back in infusion process and blood clotting fluid path block after discharge opeing and puncture phenomenon again due to woven hose Air inlet can make fluid column shorten pressure reduction, or patient's changing position cause vein pressure fluctuation when, often have blood back phenomenon, though transfusion A little blood back in pin stalk, if without continuous liquid in time is found in time, often causing blood clotting fluid path to block, must again discharge opeing, be vented, fill Liquid and puncture, not only troublesome poeration, and patient suffering can be increased and cause to waste.
(4) feed liquor of the raffinate origin cause of formation and discarding phenomenon due to connecting bottle device in infusion process or in transfusion latter stage infusion bottle Mouth is located at its tip, thus can cause transfusion bottleneck, bottleneck generation raffinate, according to its raffinate amount is surveyed mostly at 2 milliliters or so, especially Its valuable raffinate is often ignored (for example:The price of current one bottle of 50 milliliters of albumin injection liquid is 600 yuan, if 1 milliliter of residual, Its direct losses is exactly 12 yuan), [referred to last infusion bottle of the same day after previous infusion bottle stops drop or in transfusion latter stage on the same day Stop after drop to that time at the end of infusing, below (contain claims) no longer release again] together with infusion bottle and its intracavitary Raffinate is abandoned in the lump, and nurses can love generally, but disposal of having no way of.In addition, the medical personnel of neurology department arrive other often Section office discuss used albumin infusion bottle, and raffinate is applied on undergraduate course paralysed patient bedsore sore face and promotes its reparation to be cured Close, this phenomenon is just enough to show its problem place.
(5) transfusion latter stage dropping funnel, the stagnant liquid in woven hose, the raffinate origin cause of formation and discarding phenomenon are 1. when dropping funnel drips empty woven hose When descending its pressure that shortens of interior fluid column is equal with vein pressure, woven hose hypomere will show fluid stagnation phenomenon (note:It is previous Individual infusion bottle stops the liquid holdup phenomenon presented after drop in woven hose, and the present invention is referred to as stagnant liquid;The same day infuses latter stage The liquid holdup phenomenon presented in woven hose, the present invention is referred to as raffinate), its raffinate amount and vein pressure individual difference, Site of puncture and woven hose hypomere wriggle the closely related (notes such as bent circuitous degree:Therefore so-called woven hose epimere of the invention refers to That section of air inlet empty woven hose after dropping funnel drop is empty, so-called woven hose hypomere of the invention refers to show after dropping funnel drop is empty stagnant That section of woven hose of liquid phenomenon, respectively accounts for length of tube 1/2nd of infusing;Woven hose is not bisected into institute after 2,3,4 ... sections The epimere and hypomere shown;So so-called " woven hose epimere " and " woven hose hypomere " of the invention is relative, its length is big Cause, illustrate hereby);Especially precious liquid or children drop it is defeated when or primary infusion bottle in liquid residue, not only cause waste, and And can affect the treatment;To prevent precious liquid from remaining, nurse generally separately drives the washing pipes such as one bottle of G/NS, not only operates Program is cumbersome and causes new waste, and very unfavorable to the patient of limit sodium, limit sugar, limit liquid;2. due to some patientss always Worry about air can enter human body and feel fear, or it is that it pulls out pin not yet to drip empty just urgency nurse in dropping funnel;Nurse or because busy And pin is pulled out with liquid, the phenomenon abandoned in the lump together with stagnant liquid, the raffinate in dropping funnel, woven hose is very common.
《Nurse studies magazine》One is delivered in volume the 1st phase page 11 the 13rd phase in 1998 entitled " during venous transfusion to disappear Except micro-air enter vein experimental study " paper;《Quotation Analysis》(being sponsored by the Ministry of Public Health) is March in 2003 The phase page 54 of volume 19 the 3rd has delivered the paper of one entitled " discharge method of long section air under infusion process Murphy type burette " all Where the drawbacks described above that can be shown that traditional infusion device.
2nd, correlation technique defect
Liquidproof remains the formula transfusion device (patent No.:ZL00239693.9, the day for announcing:On September 26th, 2001) defect be: 1. the infusion bottle chamber of precious liquid can not be rinsed and instills human body (call in the following text can not rinse bottle and instill human body);2. it is critical to suffer from Person mostly continuously drips defeated more than ten bottles of liquid daily, because dropping funnel liquid inlet and outlet respectively has a check-valves, when dropping funnel drips empty woven hose During interior air inlet, even short section air can not the row of going up, can only using separation transfusion needle method discharge in transfusion lumen Stagnant liquid and air;Due to the discharge or repeatedly discharge of stagnant liquid, it can affect the treatment and cause on the contrary to waste, it is taken as that it is uncomfortable Defeated use continuously is dripped in conjunction;3. air, which can enter, after previous infusion bottle drop is empty makes the fluid column pressure that shortens diminish in woven hose, often cause Blood back, must discharge opeing, exhaust, topping up again even if a little blood back is also possible to occur blood clotting fluid path to block in transfusion needle stalk And puncture, not only bother, and can waste;4. in season in midwinter, after ice-cold liquid enters heating ward, it is dissolved in moisture When gases are heated, they expand in sub- gap (liquid especially in woven hose is faster than the heated liquid speed in infusion bottle), and precipitation forms attached The bubble in transfusion inside pipe wall, because the effect of check-valves is difficult to discharge it upwards, when largely transfusion gas is cumulative When, liquid interface discharge opeing, exhaust must be opened to, is not only bothered, and can waste;5. first company's bottle device of transfusion device is injected before infusing In the infusion bottle mouth put, woven hose and pinching dropping funnel are then closed, the air of its intracavitary, which is got into infusion bottle, to be made in infusion bottle The a little rise of pressure, toward transfusion device internal-filling liquid, then to carry out venipuncture.Because dropping funnel inlet is provided with check-valves, It is difficult to which the air in dropping funnel is got into infusion bottle, influence transfusion operation (refers to transfusion preparation).
Disposable multifunction safe transfusion system (the patent No.:02280389.0, the day for announcing:On October 29th, 2003) defect Must be got on understanding from microscopic techniques and feasibility:1. bottle can not be rinsed and human body is instilled;2. sandstorm, haze weather are into current state Topic on people's the tip of the tongue, and air cleaning part is configured without on the port 5 of dosing air guide three, it is a kind of exposed air guide port, opens Virus, germ, dust, small insect for being suspended in after lid in air etc. have the danger into fluid path;3. it is each on dropping funnel liquid inlet and outlet There is a check-valves, the defect that the problem of it is caused remains formula transfusion device with liquidproof duplicates, and no longer repeats;4. (referring to saying Bright book accompanying drawing 1,7,12) port 5 of dosing air guide three be located at dropping funnel above, it can cause three kinds of problems:First, can only be defeated on the same day Liquid latter stage can just uncap, and otherwise can cause woven hose air inlet and can influence metering and the prompting work(such as whether fluid path unobstructed of dropping funnel Energy;Second, the liquid that nurse must be waited in dropping funnel and woven hose epimere could make further disposal into human body naturally, because Some diseases (such as heart failure) be can not input it is too fast, i.e., using syringe inject 5 milliliters, 10 milliliters of decoctions also can set one when Between, if injection is too fast or causes problem;Third, nurse's time can be taken and be wasted, nurse is both hospital nurse and medical worker, Working is just as fighting, and its work characteristics is, it is necessary to is doctor, patient is at someone's beck and call can not delay or delay, especially runs into multidigit Patient is while when calling, weather fusion, accident or natural calamity patient uprush, the normal pressure of attending to one thing and lose sight of another of nurses is very big; Therefore, how to facilitate nurse to be conducive to patient, be that to save a little time be one the problem of need to ponder deeply to nurse;5. from See that the terminal phase of intravenous injection device for auto closing valve of its technical characteristic is rational in design principle, but it is successively near by three factories The model test of 1 year, its terminal phase of intravenous injection device for auto closing valve can not realize the Expected Results for closing fluid path, and its reason may Liquid level downstream rate slow negative pressure generating process length during with transfusion (it is slowly descending and generate negative pressure by liquid level) negative pressure value Low and (referring to Figure of description 7) cone-shaped float-type terminal phase of intravenous injection device for auto closing valve float is small from heavy and light and pressure Relevant, in addition, compared with pristine glass dropping funnel, the dropping funnel of existing transfusion device is made up of translucent soft material, by suction function it is a little to Sunken inside is deflated and offsets a part of negative pressure, and then can reduce negative pressure value and influence to close effect;6. membrane type terminal phase of intravenous injection is automatic Shut-off valve assembly is above dropping funnel, and transfusion preceding pinching dropping funnel institute's moment, which generates relatively high negative pressure, can make membrane type terminal phase of intravenous injection certainly Dynamic shut-off valve assembly is closed, and inconvenience influences transfusion operation toward transfusion device internal-filling liquid, and turns into and abandon the patent right Six factors.At least the design people does not expect problem above originally, and not yet finds pertinent literature and product at present, otherwise The application is just not present.
Weihai prestige is high in recent years, Wuhan Gao Xun, a kind of identical automatic row of many enterprises' SEPARATE APPLICATION such as Jiangxi HTC Gas transfusion device, they are the admission chambers that precision liquid medicine filter (shape such as wrist-watch, inside set two chambers) is referred to as in woven hose hypomere Outer wall center opened one or the exhaust outlet equipped with closure is constituted.Application method is:1. when previous infusion bottle drips sky In defeated pipe during air inlet and when not setting closure on exhaust outlet, continuous liquid can be directly carried out;2. when the empty transfusion of previous infusion bottle drop In pipe during air inlet and when being furnished with closure on exhaust outlet, it should first uncap and carry out continuous liquid again.They are to utilize aeroembolism in woven hose Gas is extruded exhaust outlet by the bidirection press of top fluid column pressure and vein pressure.Its exhaust mode point opens wide exhaust and uncapped when needing Two kinds of exhaust.Its defect is:1. bottle can not be rinsed and human body is instilled;2. the transfusion same day, woven hose hypomere latter stage has raffinate phenomenon, its The factors such as size, shape of the raffinate amount with being referred to as precision liquid medicine filter are closely related, according to the raffinate for surveying certain enterprise product Amount is at 8 milliliters or so;3. air, which can enter, after previous infusion bottle drop is empty makes the fluid column pressure that shortens diminish in woven hose, there is generation Blood back and fluid path block risk, or must discharge opeing, exhaust, topping up and puncture again;According to diabetes section of the second the People's Hospital of Nanning City Three nurses introduce, compared with traditional infusion device, automatic-exhaust transfusion device (such as high product of Weihai prestige, even if dropping funnel does not drip It is empty) it is easier occur blood back (mostly in patient's changing position), its reason may be with exhaust outlet (just as the exhaust of high-pressure pot cover Mouthful) a little release of pressure effect it is relevant;4. its exhaust mode is still open exhaust in any case, and simply open position is different ;Because exhaust outlet is located at woven hose hypomere, when wounds oozing of blood, open sore part pyorrhea, gatism is sneezed, and blows nose Tears, cough is spat, and water of choking is choked food, when nausea and vomiting or on one's sick bed stool and urine, is had through exhaust outlet contaminated liquid transportation work style danger;Many institute's weeks Know, the microorganism such as bacterium, virus is ubiquitous all-pervasive, since gas can be discharged from exhaust outlet, bacterium, virus etc. are caused a disease Microorganism is also possible to invade from exhaust outlet, even the probability of thousand a ten thousandths, is also avoided as far as possible, once go wrong Doctor, trouble, factory tripartite are very passive or cause tight relationship, are that a little minor issue has hair when making the event of medical personnel's homicide case It is raw;Transfusion is input after all, and closed higher than open safety, even urethral catheterization and drainage can also emphasize asking for seal Topic, will not be such that it always opens wide;Inside and outside section known to medical worker general " closed drainage bottle " is just enough to show closed It is how important to safety;5. the exhaust outlet of its exhaust outlet especially open type is appeared sweet taste, fishy smell (blood product) can be no Causing mosquitos and flies, ant, jump and disturbing etc. needs the time to observe;6. when being unworthy of closure on exhaust outlet, easily by " automatic " two word institute Mislead, because exhaust outlet is located at woven hose hypomere, once limbs of patient kills exhaust outlet, air has the danger into human body;When When being furnished with closure on exhaust outlet, the gases such as closure natural excrement must be opened and covered back again, name is said automatically, also must be manual, not only Trouble, and nurse's time can be wasted.
Patent No. 201120265273.0 it is disposable exempt to be vented continuous liquid transfusion device defect be:1. bottle can not be rinsed and dripped Enter human body;2. air, which can enter woven hose epimere intracavitary, after previous bottle liquid drop is empty make the fluid column pressure that shortens diminish, and having causes back The risk that blood and fluid path are blocked, and as two main causes for abandoning the patent right.
Patent No. ZL200320131818.4 disposable automatic liquid-stopping transfusion apparatus (producer:The health care spirit of Zhejiang Europe Medical Devices Co., Ltd, phone:0576-85289098) float valve of product is located at below dropping funnel, can not only prevent woven hose from entering Trouble caused by gas, and fluid column high pressure it is big can fluid path caused by effectively anti-return blood and blood clotting block, can especially prevent out Putting the continuous liquid mode such as formula exhaust or open discharge opeing exhaust may caused environment, fluid path pollution and occupational infection, existing part Hospital emergency department employs the product to alleviate operating pressure.But it but occurred in that after a problem is solved it is another Individual more distinct issues, that is, can cause to generate raffinate in whole piece woven hose in transfusion latter stage on the same day, according to measurement it is in kind its Raffinate amount is 10 milliliters;Especially primary infusion bottle or infantile infusion, its raffinate amount with setting amount of infusion ratio it is relatively large.Example Such as:If last infusion bottle of the same day is 50 milliliters, its direct losses is exactly 1/5th.The daily loading amount of patient is doctor's root Calculated according to factors such as weight in patients, the state of an illness, ages;Therefore, nursing college has strict demand to Nurse training, i.e., defeated Liquid is gone to (refers to transfusion preparation) when transfusion device internal-filling liquid and exhaust, just sees that transfusion needle point has overflow of drug fluid to close immediately Close fluid path, discharge decoction no more than 3 drops (water dropper of national technical standard drip for every milliliter of decoction 15), toward transfusion device in fill The operation of liquid must once succeed, and otherwise examine unqualified, must the qualified permission graduation of make-up examination.Therefore more hospital especially emphasis cures The product is mostly decline by the affiliated hospital of universities and colleges of section.Even there is the patient's refusal being expert to use the product.National Development and Reform Committee in the early time Deputy director Zhu Zhixin discloses a surprising data, and China in 2010 infuses 8 bottles per capita ... (see Guangzhou day on January 15th, 2011 Report B24).By every 2 bottle liquid medicine, with 1 transfusion device, (this allows for urgent patient and mostly drips defeated many bottles daily and most of outpatient service And basic medical unit and partial hospitalization patient per mostly drip defeated 1 bottle) every transfusion device 10 milliliters of years of residual, (4 were defeated per capita Liquid device) 40 milliliters of decoctions are wasted (after not containing woven hose air inlet in the stagnant liquid in infusion bag, infusion bottle, raffinate and infusion process Discharge opeing after fluid path caused by exhaust, discharge opeing and blood back is stifled and the waste caused by puncturing again etc.) estimation, it will be one huge Numeral, certainly the decoction of its direct losses is equally surprising.Except human factor, (such as patient lacks correct health idea will Ask garter, going after profit or gain property of public hospital, private hospital commercial activity etc.) outside, it is closely related with transfusion system structure defect.The transfusion device Defect is also resided in:Bottle can not be rinsed and human body is inputted.As the medical support system is perfect, popularize and development, the people for beating garter can also Increasing, its wasting phenomenon can also be on the rise.
The content of the invention
The present invention has benefited from once going out running into way clear soil mud stone after landslide traffic is obstructed, bores tree bottom, climbs Rubble and a variety of processing modes such as detour and be inspired.The present invention seeks to:1. disposable automatic liquid-stopping transfusion apparatus is solved Woven hose epimere intracavitary the problem of can generate raffinate;2. anti-raffinate is facilitated to operate;3. it is avoided that exposed air-guide type can Can caused fluid path pollution.The object of the invention is also resided in:When 1. dripping decoction that is defeated valuable or having strict demand to therapeutic dose, energy Raffinate in infusion bottle, woven hose is all inputted into human body;2. it will can be arranged on possible bubble in woven hose, aeroembolism, for season in midwinter Patient's continuous transfusion of section is used;3. can get into air in dropping funnel in infusion bottle before infusing makes a little rise of its internal pressure, favorably In transfusion device topping up, it is to avoid influence transfusion operation (refers to transfusion preparation);4. the quick infusion that can pressurize rescues patient.
The present invention is to solve above-mentioned skill by providing a kind of disposable auto-stopping streaming liquidproof Residual-type transfusion device Art problem.Enter liquid interface, dropping funnel, float valve, woven hose including usual and go out liquid interface, or including it is usual enter liquid interface, Dropping funnel, float valve, woven hose, go out liquid interface and the fast adjuster of drop, or including it is usual enter liquid interface, dropping funnel, float valve, woven hose, Go out liquid interface and liquid medicine filter, or enter liquid interface, dropping funnel including usual, float valve, woven hose, go out liquid interface, medical filtration Device and the fast adjuster of drop, feature is:It can will come from infusion bottle by being arranged on above woven hose in fluid path in transfusion latter stage on the same day The air inside purified imports in transfusion lumen from top to bottom/ambient atmosphere can purify in transfusion latter stage on the same day and can be by Its enclosed air guide mechanism imported from top to bottom in transfusion lumen is constituted;Or can not only liquid storage by being arranged on on liquid interface And the manual pump liquid of nurse can be supplied and then can rinse it after the infusion bottle of valuable decoction stops drop and instill human body to imitate Courage formula is rinsed a bottle eropper and constituted;Or will be come from by being arranged on above woven hose in fluid path the latter stage that can be infused on the same day in infusion bottle The air purified is imported in transfusion lumen/can purified ambient atmosphere progress in transfusion latter stage on the same day and can be by it from top to bottom From top to bottom import transfusion lumen in enclosed air guide mechanism and be arranged on on liquid interface can not only liquid storage and also can for protect The manual pump liquid of scholar so can the infusion bottle of valuable decoction stop drop after it is rinsed and instill human body imitative courage formula rinse bottle drip Enter device to be constituted.Described enclosed air guide mechanism be it is a kind of can in advance open for nurse, with closing/open in advance/after the atmospheric pressure conduction opened Mechanism;So-called " opening in advance " refers to that described enclosed air guide mechanism can be for nurse while last infusion bottle of the continued access same day (advance) unlatching makes fluid path unimpeded conveniently;So-called " with closing " refers to then described when conditions of patients mutation need to add drops physic liquor temporarily Enclosed air guide mechanism can be whipped for nurse close so that the valve element of float valve can be made to return to automatic open close fluid path state and continue Transfusion;So-called " opening afterwards " refer to described enclosed air guide mechanism can at least be infused for nurse on the same day latter stage it is manually opened and then Atmospheric pressure (containing the atmospheric pressure in infusion bottle, two kinds of situations of external atmospheric pressure) can be imported woven hose from top to bottom Intracavitary;So-called " enclosed air guide mechanism ", it is for exposed air guide port, and indirect to import ambient atmosphere Mechanism [note in transfusion lumen:The application essential feature problem has been specially interviewed save between Guangzhou four, in five of City Hospitals, Senior nurse practitioner thinks that transfusion device does not include transfusion needle, liquid medicine filter and the fast adjuster of drop.Do not include the foundation of transfusion needle It is:1. it is not only to be flexibly connected between transfusion needle and transfusion device, and the product for having different model and individually packing is selected for nurse Match somebody with somebody;2. the new technology such as transfusion catheter, needleless seal nipple, infusion tee cock is rapidly developed and extensive use in recent years, It can also be discarded equipped with transfusion needle even if in transfusion device packaging bag;③《Chinese Quotation Analysis》(by Chinese Medical Association master Do) one has been published in the 9th the first tenday period of a month phase of volume 22 version page 54 in September, 2006, and entitled " can carrying out good fortune, (needleless sealing connects Head) novel clinical use " paper;《Modern Nursing magazine》Published in November, 2001 in the 62-63 pages of the o. 11th of volume 7 The paper of one entitled " application of the no-needle transfusion system in child vein retention transfusion ", can be shown that traditional infusion device not Including transfusion needle;But it is to supply grafting remaining needle calparine cap equipped with transfusion needle still to have infusion segment device product at present, therefore the application will It is incorporated to out described in liquid interface.Not including the foundation of liquid medicine filter is:1. it is no decoction on original emulsion tube transfusion device Filter, belongs to the transfusion device that sterilization capable of washing is reused, and is both also used for transfusing blood (now adopting now defeated) for infusing;2. after opening The country occurs in that the plastic pipe transfusion device provided with liquid medicine filter;But the design people is attached in Nanfang Medical Univ in recent years A kind of disposable precision liquid medicine mistake that can be flexibly connected with woven hose end fitting is seen by the medical institutions such as emergency department of Nanfang Hospital Filter (producer:Fu'erte Tech. Co., Ltd.,Beijing, factory site:BaDaChu High Science & Technology Park, Shijingshan District, Beijing City undertaking area A Seat);It is said that with medical technology pharmaceutical technology progress, the kind of decoction increases (such as increasingly:Crystal, colloid, suspension, fat Nutrient solution, blood product, Chinese medicine preparation etc.), different liquids have different physical behaviors, and daily amount of infusion difference is very big, no Purification of the different types of liquid of same amount to liquid has different requirements, the separately production individually packaging therefore part producer is classified Matched temporarily for nurse;3. it is no liquid medicine filter such as in Spain, the transfusion device of Ireland developed country, this may It is advanced relevant with their pharmaceutical technologies;It is therefore contemplated that transfusion device does not include liquid medicine filter.The fast adjuster of drop is not included According to being:1. original emulsion tube transfusion device is fast highly to adjust drop by regulation transfusion kettle (equivalent to infusion bottle), later Professional is additionally arranged the fast adjuster of twin-screw clip drop of metal in colloid transfusion pipe outer wall and can dismounted at any time, companion in succession With colloid woven hose aging and discarded, the fast adjuster of its metal screw clip drop may be mounted to be continued to make on new woven hose With;It is domestic after opening some plastic pipe transfusion devices equipped with the fast adjuster of race clip drop of knowing clearly occur, largely Facilitate nurse operation;But Guangzhou No.1 Hospital Affiliated to Zhongshan Univ. has introduced a kind of movable liquid that is connected to out and connect in recent years (the transfusion extension tube provided with titration adjuster, can be according to the mark on titration regulator handle and doctor for the fast adjuster of drop on mouth Advise and disposably fast regulate amount of infusion set per hour exactly, not only saved trouble but also safety, thoroughly eliminated nurse and look at Clock and watch number drop number and adjusts the trouble that the fast adjuster of race clip drop is brought back and forth), the race clip drop on traditional infusion device Fast adjuster is abandoned;2. the infusion pump of configurations is used widely in intensive care unit in recent years, traditional infusion device On the fast adjuster of consumptive material class drop often abandoned;It is therefore contemplated that transfusion device does not include the fast adjuster of drop.But still there is portion at present The infusion apparatus product of man of subsidiary factory is to be used equipped with the fast adjuster of drop and/or liquid medicine filter for basic hospital.Based on case above, The present invention gives four kinds of versions in the preamble of above-mentioned technical proposal (i.e. claim 1), if Patent Office thinks the application There is defect or redundancy due to misprinting in terms of word in file, or certain version of its preamble lacks liquid medicine filter and/or the fast adjuster of drop Deng necessary parts, or its characteristic lacks Manual pressurization pump etc., and the application sincerity welcomes Patent Office and audit crew examining (without analysis or commentary) is directly pointed out in Action, and agrees to delete illegal version in preamble, also agrees to increase Plus Manual pressurization pump.Welcome to grant to change model for our information, the application will give and respect fully, and spy gives explanation].
Further, then can be in the woven hose when being provided with enclosed air guide mechanism in the fluid path above the woven hose The upper Manual pressurization pump for setting one kind that its (referring to woven hose) intracavitary raffinate can be inputted to human body.
Further, described imitative courage formula rinses bottle eropper by being arranged on into the capsule pipe on liquid interface, utricule and can open and close capsule The switch of pipe is constituted;Described utricule is that a kind of energy being made up of medical flexible material supplies nurse's manual squeezing pump liquid and energy By means of capsule pipe and enter reservoir (appearance) device of liquid interface and infusion bottle chamber insertion.
Further, described Manual pressurization pump can be by being arranged on pars infrasegmentalis under woven hose/woven hose hypomere middle part/transfusion Pipe lower section upper portion (being preferred site) can for nurse's manual squeezing pump liquid pressurized capsule and be separately positioned on the pressurized capsule into and out of Check-valves on liquid mouthful is constituted.
Further, described Manual pressurization pump can also be by being arranged on woven hose pars infrasegmentalis under pars infrasegmentalis/woven hose ( For preferred site) pressurized capsule of nurse's manual squeezing pump liquid can be supplied and opening in the pressurized capsule upper and lower fluid path is separately positioned on Pass is constituted;When the fast adjuster of drop is provided with the fluid path above the pressurized capsule, then the institute in fluid path above pressurized capsule can be omitted State switch.

Embodiment
Embodiment 1:
As shown in Figure 1, 2, it enters liquid interface by side-hole needle 1, dropper 2 and the purification type airway tube 3 equipped with air cleaning part 4 (conduit of balance infusion bottle external and internal pressure, practise and claim blast pipe) is constituted.Also side-hole needle 1 can be placed directly onto at the top of dropping funnel and net Change type airway tube 3 is collectively formed into liquid interface.Purification type airway tube 3 should be also planted even if using infusion bag transfusion, is reduced as far as possible Stagnant liquid, raffinate.By usual transfusion catheter 11 and short section elastic tube 14, (its effect is woven hose equipped with the fast adjuster 10 of drop:① During venipuncture pinching it can rebound can promote blood back with confirm puncture whether succeed;2. can malleation pull out pin, that is, in pinching Pin is pulled out to prevent ecchymoma or pin mouthful oozing of blood) constitute.Pipe end of infusing is provided with liquid medicine filter 13.Take out the nipple of liquid interface Shape (cone) joint 12 can supply the socket of liquid pintle.Float valve 7 is located at the lower section of water dropper 5 (Fig. 1 is below dropping funnel), the energy of locating part 6 Fluid path [note is blocked up on anti-valve element:Omit visual float valve after the locating part 6 between dropping funnel and float valve housing and be located at dropping funnel bottom (i.e. Float valve matches well with dropping funnel, and dropping funnel bottom tube wall doubles as float valve housing, and valve element is located at dropping funnel bottom, it may also be said to be that float valve housing is simultaneous Make dropping funnel bottom tube wall), no longer release again below].The groove of valve element bottom centre embeds flexible sealed piece.On the wall of valve element side It is vertically directed drain fin 8 (being usually more than three) and fit clearance is provided between the wall of float valve side, is freely floated keeping valve element Under the premise of dynamic it can be made to be always at vertical state to ensure to close effect.Compared with the float of Multifunctional safety transfusion system, this The heavier pressure of valve element is larger and is embedded with flexible sealed piece, practice have shown that fluid path can be closed conscientiously.Enclosed air guide mechanism is opened for one kind It is located on float valve liquid outlet and can be supplied equipped with air cleaning part (the air cleaning film for being located at its intracavitary) and opening and closing element (closure) Open down to postpone after nurse and open formula purification type air guide port 9, transfusion latter stage opening closure (i.e. so-called energy is opened after supplying nurse) just can Ambient atmosphere purify and can import it in transfusion lumen from float valve liquid outlet and woven hose upper end, and then can be prevented defeated Liquid pipe epimere generates raffinate, and transfusion needle is pulled out when observing that woven hose inner liquid medicine stops descending and terminates same day transfusion.Its principle Just as the tracheotomy ventilation after larynx tumour airway obstruction.Its weak point is:Nurse need to wait woven hose epimere raffinate certainly It is dynamic to make further disposal into human body, it is more time-consuming, therefore be classified as and time select embodiment.As shown in figure 3, when float valve is located at drop During first 5 top (i.e. the top of dropping funnel 18, is no longer released below) again, then formula purification type air guide port can be opened by after and is set to the top of dropping funnel 18 On (upper 1/3rd, not separately map) or float valve liquid outlet, and it can be renamed as postponing and open formula purification type air guide port 16.Separately When float valve housing and dropping funnel tube wall disjunctor (still as shown in Figure 1), then need to open the setting of formula purification type air guide port by after to dropping funnel Portion's (not mapping separately) simultaneously can be belonged to the category for postponing and opening formula purification type air guide port.Transfusion latter stage opens opening and closing element and (opened 17) close just can carry out ambient atmosphere purifying and importing it in transfusion lumen via dropping funnel inner chamber and woven hose upper end, with Anti- dropping funnel 18 and woven hose epimere generate raffinate.The float valve inlet 15 of angle can block up fluid path on anti-valve element, therefore can be regarded as Locating part.Float valve, dropping funnel and pinching dropping funnel are first inverted before transfusion and gets into its chamber air in infusion bottle makes a little liter of its internal pressure Height, then toward transfusion device internal-filling liquid.Compared with the membrane type terminal phase of intravenous injection device for auto closing valve 3 of Multifunctional safety transfusion system, pinch Crowded this dropping funnel institute's moment, which generates relatively high negative pressure, to be closed float valve, and favourable transfusion device topping up does not influence transfusion Operation.The embodiment is mainly used in large transfusion bottle, cheap and defeated to the drop of dose requirements not bery strict decoction, to reduce raffinate Measure (note:The connected modes of following examples, application method, the shape of functional effect and enclosed air guide mechanism, shift in position and Be present identical situation in its title change etc., be not described in detail).
Embodiment 2:
As shown in figure 4, it enters liquid interface 20 by the plug bottle connector 22 equipped with purification type air guide port 21 (practise and claim exhaust outlet) And dropper equipped with the fast adjuster 10 of drop and indicate buret 23 of the scale provided with suspender 19 and constitute.The fast adjuster 10 of drop is used for Control Discharge rate.The bottom of dropping funnel 28 is provided with liquid medicine filter 29.Water dropper (droplet water dropper) 27 is used for children's drop is defeated.Float valve 25 In the top of water dropper 27.Feeler sample locating part 24 on valve element can block up fluid path on anti-valve element.Enclosed air guide mechanism is to be arranged on float valve Can in advance it be opened for nurse on liquid outlet and float valve side wall and equipped with 17 (slide fasteners) of switch, with putting controllable type bypass type airway tube on closing 26, being opened (i.e. so-called in advance to be opened for nurse) conveniently while last infusion bottle of the continued access same day just can be at transfusion end The air purified in infusion bottle (is the cleaned air of purified type air guide port 21, hereinafter referred to as infusion bottle by the phase Interior air) enter certainly in liquid interface 20, float valve 25, the inner chamber of dropping funnel 28 and woven hose upper end importing transfusion lumen, it just can prevent drop Bucket 28 and woven hose epimere generation raffinate.When conditions of patients mutation need to add drops physic liquor temporarily, it can conveniently close and put controllable type Bypass type airway tube 26 makes valve element return to automatic open close fluid path state (i.e. so-called can be for nurse with closing).When above putting by controllable type The upper end of road type airway tube changes when being located at on liquid interface 20 (not mapping separately), then renames as putting and led around valve controllable type bypass type Tracheae, pre- breakdown close 17 just can in transfusion latter stage by the air in infusion bottle from entering liquid interface 20, the inner chamber of dropping funnel 28 and defeated Liquid pipe upper end is imported in transfusion lumen.Its principle is just as the navigation channel of Three Gorges Dam side.With the exposure of Multifunctional safety transfusion system Formula air guide port 5 is compared, time saving, closed, nimble, safe.If the lower end that controllable type bypass type airway tube 26 is put by, which changes, is located at drop On bucket 28, dropping funnel function can be influenceed surely;Therefore can only after open, also have liquid in transfusion latter stage dropping funnel, nurse need to wait until dropping funnel and The emptying of woven hose epimere could make further disposal, can waste nurse's time, therefore be classified as time time choosing (the secondary secondary choosing chosen) Embodiment.Manual pressurization pump can extrude pump liquid by being arranged on pars infrasegmentalis on woven hose (referring to 1/3rd under epimere) for nurse Switch 17 on pressurized capsule (ball) 35 and its upper and lower fluid path is constituted.First close the top fluid path of pressurized capsule 35 and gently pinch pressurized capsule again Raffinate in woven hose can be inputted human body by 35, close the lower section fluid path of pressurized capsule 35 immediately when observing that raffinate fully enters human body With anti-blood back, then pull out transfusion needle and terminate same day transfusion.It is to infuse latter stage that pressurized capsule 35, which is located at pars infrasegmentalis reason on woven hose, Its inner chamber is empty, and input raffinate is more convenient, time saving, safe.Be unfavorable for if the position of pressurized capsule is too high operation, this be because What nurse's eyes were dig-inned is the liquid flow of air situation in infusion needle guide tube during for input raffinate.If pressurized capsule is set and arrives woven hose Hypomere, must alternately open and close the fluid path of the upper and lower of pressurized capsule 35 and repeat pinching pressurized capsule 35 could input human body by raffinate, and this is Because latter stage pressurized capsule 35 of infusing is full (also having raffinate), raffinate human body could be fully entered after must pressurized capsule be emptied, It is more time-consuming and dangerous because some patients, medicine be can not input it is too fast, if control it is bad or cause problem.Pressurized capsule Volume slightly larger than woven hose hypomere volume to be advisable, because can not possibly all discharge its intraluminal fluid, gas during pinching pressurized capsule.Slightly Small pressurized capsule can also be used, and being repeated during input raffinate more than once is.If specializing in the patient fluid infusion in season in midwinter, Pressurized capsule can be set to pars infrasegmentalis (referring to 1/3rd under hypomere) under woven hose hypomere any part especially woven hose, first closed Pinching pressurized capsule can go out possible bubble in woven hose upwards to the lower section fluid path of pressurized capsule 35 again;One is repeated during input raffinate It is secondary or once more than be.The top of pressurized capsule 35 provided with the fast adjuster 36 of drop (transferred the files the fast adjuster of adjustable type drop for import, it Upper and lower part can make stone mill type relative rotation and be adjusted, and screw and be adjustable within one week maximum, be minimal to closing, the existing class in the country Like product).Transfusion pipe end is connected with liquid medicine filter 34 (for existing accurate filter schematic diagram).Take out liquid interface Moveable cap button joint 32, its cap buckles 31 (nuts) can not only make that horizontal direction is relative to be turned around the vertical pivot of mammiform joint 30 It is dynamic, and can be slided up and down along inlet 33 that the outer wall of mammiform joint 30, its positive effect is:Can not only be with transfusion The spiral shell button-type pintle of pin spins to be come off to prevent unexpected, and that infundibulate pintle that energy ribbon supply has disjunctor protecting cover is socketed.Such as Fig. 5 Shown, float valve is located at below water dropper 27 (dropping funnel 37).Enclosed air guide mechanism is to be arranged on float valve liquid outlet and the tube wall of dropping funnel 37 And equipped with the underlying around valve controllable type bypass type airway tube 39 of switch 38;It constitutes U pipe relations with dropping funnel 37, and water dropper 27 is not influenceed Function.Pre- breakdown close 38 just can in transfusion latter stage by the air in infusion bottle from entering liquid interface 20, the inner chamber of dropping funnel 37 and defeated Liquid pipe upper end is imported in transfusion lumen.Similarly, it is located at float valve side when the underlying upper end around valve controllable type bypass type airway tube 39 changes (do not mapped separately) when on wall, then rename as underlying controllable type bypass type airway tube, open it just can incite somebody to action in advance in transfusion latter stage Air in infusion bottle is imported in transfusion lumen from liquid interface 20, dropping funnel 37, float valve inner chamber and woven hose upper end is entered.It is not difficult Understand, be set to if the underlying upper end around valve controllable type bypass type airway tube 39 is changed on liquid interface 20, dropping funnel work(can be influenceed surely Can, thus it can only after open, therefore be classified as time and time to select embodiment.Certainly, also medicine can be set in the intracavitary of buret 23 or dropper Liquid filter, and then liquid medicine filter 29,34 can be omitted.It is to prevent that liquid medicine filter 29, which is set above woven hose, The possible residual gas separate out of its intracavitary enters human body, and perhaps a little gas enters in adult body will not produce serious consequence, but It is dangerous just big (this kind of situation may be occurred in liquid medicine filter changing position by referring to) in into children's body.The present embodiment accompanying drawing Appeared in two liquid medicine filters, simply indicate that it has numerous embodiments, do not suggest that a transfusion device need to set one Above liquid medicine filter.Float valve, enclosed air guide mechanism and Manual pressurization pump is set especially to weigh on youngster's burette type transfusion apparatus Will the reason for be:1. fluid path caused by woven hose air inlet and blood back being prevented is blocked, and because the tiny cooperation of child vein is difficult, then is punctured More bother;2. infantile infusion total amount is few, and raffinate amount and the ratio for setting amount of infusion are relatively large.In addition, when on pressurized capsule 35 When side is provided with drop speed adjuster, then the switch 17 above it can be omitted, because the fast adjuster of drop also has the work(for closing fluid path Energy.But when this kind drips fast adjuster 36 and be located in the lower section fluid path of pressurized capsule 35, preferably retain in the lower section fluid path of pressurized capsule 35 Switch 17 need both hands to coordinate because closing the fast adjuster 36 of drop, it is inconvenient.
Embodiment 3:
As shown in fig. 6, it enters liquid interface by two plug bottle connectors 40 and the (Y shape equipped with the fast adjuster 10 of drop of dropper 41 Transfusion catheter) constitute, controlled for tall person nurse's regulation drop speed, liquid transition and anti-raffinate.Transfusion provided with grafting interface 49 Pipe 50 is provided with liquid medicine filter 34.Cap button joint 47 is distinguished with moveable cap button joint 32:The cap of cap button joint is buckled It is that outer wall can not be slided up and down along mammiform joint inlet.Float valve is located at the top of water dropper 5.Enclosed air guide mechanism For put in one kind it is pre- open formula float valve, it is by deformable float valve housing (being made up of medical flexible material can be deformed with bending) and valve element Constitute.Valve element is constituted by being provided with delivery hole 43 and being embedded with the sleeve 44 and drain pipe 45 of flexible sealed piece 42.Flexible sealed piece 42 And/or sleeve 44 is made up of light material (referring to proportion less than water).Drain pipe 45 is made up of hard brittle material, and its stage casing is close can The horizontal cut 46 (just as cut on water for injection Ampoule neck) for deforming float valve housing cavity bottom can be for nurse on the continued access same day Smoothly broken disconnected across deformable float valve housing while last infusion bottle, i.e., it is so-called to be allowed to for nurse's equalizing valve core Displacement makes fluid path unimpeded, and then in transfusion latter stage (can above put from liquid interface, float valve is entered and pre- open formula the air in infusion bottle Float valve), the inner chamber of dropping funnel 18 and woven hose upper end import the intracavitary of woven hose 50.Its principle releases obstruction just as excision intestinal cancer.Manually Force (forcing) pump is on the pressurized capsule (pipe) 48 and its upper and lower fluid path of pars infrasegmentalis under the pars infrasegmentalis on woven hose 50 or woven hose The fast adjuster 10 of drop is constituted.First closing the fast adjuster 10 of drop above pressurized capsule, gently crowded pressurized capsule 48 can be defeated by raffinate in woven hose again Enter human body, be then shut off the lower section of the pressurized capsule 48 fast adjuster 10 of drop with anti-blood back, then pull out transfusion needle and terminate same day transfusion.Separately The problem that need to be pointed out is that the roller of the fast adjuster 10 of lower section drop of driving pressurized capsule 48 can make liquid gas in infusion needle guide tube downwards Continue to move down about 4 centimeters, thus should retain appropriate amount of fluid when pinching pressurized capsule 48 inputs raffinate, to prevent closing the fast adjuster of drop Its lower air can be pressed into human body when 10, therefore strict training and examination must be carried out to nurse, more bothered.If velocity modulation will be dripped Save after device 10 is inverted and be arranged on that section of woven hose of the lower section of pressurized capsule 48, can cause blood back when closing it, it is taken as that plus It is the most suitable to end switch as chuck, slide fastener etc. to press the lower section of capsule 48.As shown in fig. 7, when identical or similar with Fig. 6 pre- Opening formula float valve, [it, which is included, is located at below dropping funnel and (does not map separately) or positioned at two kinds of dropping funnel bottom set-up mode positioned at the lower section of water dropper 5; Fig. 7 is that dropping funnel bottom, i.e. valve element are located at dropping funnel bottom, and drain pipe activity is inserted in dropping funnel liquid outlet, and dropping funnel bottom tube wall is doubled as Float valve housing] when, then rename as it is underlying it is pre- open formula float valve 51, bending of being whipped while last infusion bottle of the continued access same day " dropping funnel " bottom makes drain pipe disconnection (dislocation) just can open valve element, i.e., so-called energy be allowed to displacement for nurse's equalizing valve core makes fluid path It is unimpeded, and then can be (underlying pre- to open formula float valve from liquid interface, dropping funnel, float valve is entered by the air in infusion bottle in transfusion latter stage 51) inner chamber and woven hose upper end import the intracavitary of woven hose 50.Separately as shown in fig. 7, due to dropping funnel tube wall and deformable float valve housing Being made by medical flexible material can be deformed with bending and without clear and definite boundary line, therefore, if being positioned at " dropping funnel intracavitary " with valve element By and then being said to be built-in and opening formula float valve or other title in advance, these, which all fall within, of the invention underlying pre- opens formula float valve Category within.
