Background technology
At present by the widely used precise transfusion flow regulator in clinical transfusion field mainly by upper adjustment disk, lower adjustment disk be clipped in flexible gasket (generally selecting silica gel material manufacture) between two dishes and form, upper and lower two adjustment disk coaxial rotatings connect.On upper and lower adjustment disk, be respectively equipped with inlet opening and liquid outlet, be provided with liquid pass hole on flexible gasket, be provided with liquid stream road between two adjustment disks, cross liquid stream road and be communicated with inlet opening and the liquid outlet on upper and lower adjustment disk, crossing liquid stream road is variable section structure.The concrete shape of crossing liquid stream road has multiple, such as application number is: 01270179.3, name is called: the patent of invention of infusion flow adjuster, what disclose the descending annular groove shape gradually changing of a kind of sectional area crosses liquid stream road; Application number is: 99219623.X, name is called the patent of invention of flow regulator, discloses the liquid stream road excessively of a kind of one week cutting shape from deep to shallow etc.Be equipped with infusion tube jointing with holes in the position of inlet opening of upper adjustment disk and the position of the liquid outlet of lower adjustment disk, two jointings are connected with the infusion tube at two ends respectively.Center at lower adjustment disk is provided with joint pin, considers with the stability angle being connected from the sealing of moulding process, connection, and joint pin, with certain tapering, is designed with cannelure in joint pin upper end.On upper adjustment disk, be designed with the plug-in opening matching with joint pin, be designed with resilient sleeve in the upper end of plug-in opening, resilient sleeve is made up of the multiple flexure strips along circumference, and the upper end medial surface of each flexure strip is equipped with self-locking tooth.In the time of assembling, self-locking tooth is embedded in the cannelure of joint pin, and then realizes the assembling of upper and lower adjustment disk and locking vertically.In addition, at the lateral surface of lower adjustment disk near being provided with the position that upper adjustment disk is combined multiple scale markers of along the circumferential direction arranging, each scale marker is made up of graduation mark and milliliter numerical value, on the lateral surface of upper adjustment disk, is designed with sign, conventionally represents with arrow.In the time that upper and lower adjustment disk relatively rotates along center, can change the size of amount of infusion, the ml vol of specifically infusing can be determined by the corresponding scale marker of arrow.Hold upper and lower adjustment disk for ease of nurse and carry out Flow-rate adjustment, also can on the lateral surface of upper and lower adjustment disk, away from both faying face positions, the anti-skidding projection along circumference be set.Above-mentioned two adjustment disks are once injection moulding structure.
That this precise transfusion flow regulator has is easy to adjust, advantage efficiently, eliminate common handwheel slide rail type infusion flow adjuster governing speed relatively slow, and need the deficiency of number number of infusion drops and degree of regulation not good enough, particularly thoroughly overcome the displacement out of control that handwheel appears in common handwheel slide rail type infusion flow adjuster occasional, the disadvantage that causes liquid input to strengthen suddenly.This precise transfusion flow regulator is a kind of flow regulator that has very much using value.
And the disadvantage that this precise transfusion flow regulator exists is not have specially locking and the regulatory function of control of medical personnel.And be some specialized factory, want for many years to solve but the difficult problem that could not solve.Its consequence is to cause doctor and patient all can arbitrarily regulate input flow rate.And in real clinical transfusion, through investigation, approximately have patient or the families of patients of 6-12% (outpatient is more), and always think to complete as early as possible transfusion, can carry medical personnel, stealing and tuning up transfusion speed.And most medicinal liquids are according to the character of medicinal liquid and points for attention, all can clearly accuse can not be defeated too fast, for example Folium Digitalis Purpureae is exactly definitely can not be defeated fast, no person is just in peril of one's life.(even for example Patients with Cardiac Failure is normal saline defeated, once too fast to also have a lot of diseases, also can inspire heart infarction and pulmonary edema), be to need the strict medicinal liquid of controlling to drip speed, no person there will be serious infusion reaction, and individual other even can be paid dead cost.By statistics, this phenomenon that privately tunes up transfusion speed, has the gesture of rising year by year, traces it to its cause as follows: 1, because of the development of market economy with deeply, cause people's life, work, the quickening of study rhythm and the anxiety of time and not enough.Impel some because being pressed for time, be difficult to ensure longer infusion process and time, and blindly privately tune up transfusion speed.2, popularizing and improving along with medical knowledge, make people there is preliminary understanding to medical science, but the utmost point is unprofessional, be at most the state of having half knowledge, take for quickening transfusion speed and there is no risk, but do not know because privately tuning up transfusion speed, bring serious actual bodily harm and economic loss can to oneself or family, or even the cost of life.Although for a concrete patient, may tune up once, twice serious infusion reaction all not occur, that is to say that patient privately tunes up transfusion speed majority and can absolutely not occur serious infusion reaction, once but there is serious infusion reaction, even cause death, as long as once, concerning patient and patient family, that is definitely 100% massive losses so.And this because patient tunes up the infusion reaction that transfusion speed causes privately, every day, monthly, annual all at the potential patient of the 6-12% left and right of various places, light or heavy is occurring.This superficial by mistake knowing become invisible killer.Also increased misunderstanding and the dispute between doctors and patients, made medical personnel when physical ability is paid, also will pay the strike of spirit simultaneously.Because patient tunes up after transfusion speed, once there is serious consequence, some patients are for oneself private interests, will be contrary to one's convictions deny that oneself once tuned up transfusion speed privately.Cause individually dead patient because of dead, cannot talk clearly, can not talk clearly, can only bear and swallow humiliation and bear a heavy load by medical personnel.3, due to the enhancing of medical care both sides legal consciousness, both sides' distrust is deepened, and makes medical personnel in the time of medication and transfusion, under specific environment.Make some patient produce erroneous judgement, think that medical personnel are for safety self-protective or timidity, transfusion speed can be had a mind to slow down; now; patient or families of patients, for improving therapeutic effect or alleviating the painful consideration of transfusion, will oneself be decided, and are privately stealing and are tuning up transfusion speed.4, some patient tune up for the first time transfusion speed do not cause uncomfortable reaction (majority be because of disease lighter, single amount of infusion is less, the reasons such as medicinal liquid is not only safe but also gentle), regard omnipotent experience, cause having produced Double Dare, no matter be what medicine of what disease, all private is adjusted and is accelerated a speed without exception, finally probably can lead to serious consequence later.

In said structure, dedicated lock adjusts the concavo-convex plug-in mounting fit structure between spanner and resilient sleeve preferably to adopt following two kinds of structures:
The first structure: be at least provided with an inner convex rib 51 on the medial wall that dedicated lock adjusts spanner to coordinate with resilient sleeve, described inner convex rib is inserted in the opening between adjacent flexure strip, forms described concavo-convex plug-in mounting fit structure.Concrete, adjust the bottom of spanner to be provided with the jack matching with resilient sleeve at dedicated lock, inner convex rib is located on the medial wall of jack.This concavo-convex plug-in mounting fit structure is referring to accompanying drawing 5 and 6.
The second structure: the lateral surface of at least one flexure strip is provided with an outer convex rib 111, dedicated lock adjusts spanner to be provided with the slot 52 consistent with described outer convex rib quantity with the medial wall that resilient sleeve coordinates, outer convex rib and slot one by one plug-in mounting coordinate, and form described concavo-convex plug-in mounting fit structure.This concavo-convex plug-in mounting fit structure is referring to accompanying drawing 3 and 4.
In said structure, dedicated lock adjusts spanner to be made up of sleeve 53 and handle 54, and described sleeve is connected with resilient sleeve.Sleeve and handle can adopt Split connection structure, also can adopt integrated injection molding structure, and in the present invention, dedicated lock adjusts spanner preferably to adopt integrated injection molding structure.
Above-mentioned dedicated lock adjusts the effect of the handle on spanner to be: the revolving force of adjusting spanner in order to increase dedicated lock, reduce the torsion of finger in the time of operation, realize the object that any nurse all can easily rotate adjustment disk, complete the rotation of adjustment disk and lower adjustment disk, realize and open, regulate, close and lock.Handle is preferably as follows two kinds of structures:
The first structure: described handle is butterfly shape, it is made up of two symmetric parts with respect to sleeve center.This handle arrangement is referring to accompanying drawing 1-6.
The second structure: because be designed with infusion tube jointing on upper adjustment disk, in order to further facilitate medical personnel's the agility of operation.More preferably unsymmetric structure of described handle, by with respect to sleeve center, one is long and the other is short, two parts form for it.When installing or using, can be by a side shorter handle near infusion tube, by long side back to infusion tube and jointing, thereby while having avoided practical operation, finger occasional contacts infusion tube, and a little operation bringing is inconvenient.This handle arrangement is referring to accompanying drawing 7 and 8.
This precise transfusion flow regulator is on the basis of former accurate flow regulator, do not changing original main key structure, do not change under the original function of former accurate flow regulator and the prerequisite of transfusion precision, only by increasing by three not only simple but also cheap accessories, and the non-key position of former accurate flow regulator is improved a little, and make flow regulator there is new function, realize new innovation and creation.
Three accessories are connected and specifically act as with the concrete of existing structure:
1, upper adjustment disk separation sleeve: hold between the circumference line of anti-skidding protruding block and the circumference line of transfusion graduation mark and be designed with a circle seam 22 (seeing Fig. 3) at the cylindrical of lower adjustment disk, upper adjustment disk separation sleeve plug-in mounting is also fastened on this seam, play the periphery that patient cannot touch adjustment disk, and then cannot realize the object that privately tunes up transfusion speed.On upper adjustment disk, lower adjustment disk spray printing, after due mark and scale, can, by solid to this transparent upper adjustment disk separation sleeve and the first luggage of lower adjustment disk, assemble and locking with upper adjustment disk and flexible gasket more afterwards.Why like this design, to have the following advantages because of tool: 1) in application, accurate flow regulator with transparent separation sleeve is guaranteeing that patient cannot touch under the prerequisite of outer peripheral face of adjustment disk, also can see clearly whole marks and the scale on actuator clearly, be convenient to carry out accurately and conveniently Flow-rate adjustment.2) this kind of design, has just carried out improving slightly at the outer peripheral face of lower adjustment disk and upper adjustment disk, the essence structure of upper and lower adjustment disk is not done to any change, thereby can not affect the precision of this flow regulator.3) come upper adjustment disk insulation blocking as lower adjustment disk being directly injected into one extended type; also can make patient cannot touch adjustment disk periphery; but because the joint pin upper end of lower adjustment disk must be provided with cannelure, in reality processing injection moulding, must there is moving back a difficult problem for mould.Therefore adopted the plug-in mounting structure of transparent separation sleeve and lower adjustment disk, overcome above-mentioned shortcoming of moving back mould difficulty.4) this septum pellucidum is from applying mechanically transparent macromolecular material once injection moulding structure.
2, disk cover: disk cover is inserted solid in upper adjustment disk upper port.The plug-in mounting structure of disk cover and upper adjustment disk plays the lever force that prevents that patient from utilizing the interaction of the fit structure of infusion tube jointing and resilient sleeve and joint pin to form, in realization, the mutual rotation of adjustment disk and lower adjustment disk, reaches the object that privately tunes up transfusion speed.This disk cover is disposable injection molding molding structure.
3, dedicated lock adjust spanner: dedicated lock adjust spanner be connected with the resilient sleeve in former precise transfusion flow regulator by the bellmouth being located on sleeve, and and resilient sleeve between be provided with concavo-convex plug-in mounting fit structure.This structure takes full advantage of the engagement formation of existing resilient sleeve and joint pin, is at the once successful ingehious design not destroying under original structure prerequisite.Because dedicated lock is adjusted spanner and existing structure employing cone match, existing Quick fastening lock function, has again the laborsaving timesaving of plug feature.Adopt this kind of cone match project organization, can thoroughly avoid dedicated lock to adjust spanner in certain vibrations link of assembling, stock, transportation, carrying, mutually depart from accurate flow regulator, cause in the time of clinical transfusion, nurse need adjust spanner to be inserted on accurate flow regulator the dedicated lock coming off again, causes the increase of waste of time and operation sequence.This dedicated lock is adjusted the good macromolecular material of spanner usable intensity (for example ABS engineering plastics) once injection moulding.
This precise transfusion flow regulator is in the starting stage of design, just through research and experiment repeatedly and met four standard-requireds of flow regulator: the too small restriction in environment and space of 1) being infused, the volume of this actuator can not obviously exceed the volume of former actuator.2) limited by the gross weight of transfusion device, the weight of this actuator can not obviously exceed the weight of former actuator.3) time restriction that need race against time while being subject to emergency call salving patient, this actuator is more convenient using in operation, better more fast.4) modulated device is the restriction of medical disposable material, and the design of this actuator and manufacturing cost are more low better.Therefore, guarantee meet under the prerequisite of above-mentioned 4 standard-requireds, through the continuous failure of 3 years, finally succeed in developing have medical care specially control lock conditioning function precise transfusion flow regulator.This actuator medical personnel regulate medicinal liquid infusion drip fast in, can synchronously realize the locking to this actuator.This precise transfusion flow regulator is by repeatedly studying, manufacturing experimently and realize for many years.This precise transfusion flow regulator adjusts spanner to realize adjusting, unlatching and the lock function of this actuator by inserting solid upper adjustment disk separation sleeve, the slotting solid disk cover in upper adjustment disk upper port and dedicated lock on lower adjustment disk.Dedicated lock adjusts spanner to have extremely strong motility, both can insert fast connection, can be extracted easily again, and be carried by medical personnel, adjusts spanner therefore be called medical care dedicated lock.In clinical transfusion, as long as medical personnel are regulating after amount of infusion, under the prerequisite of not changing hands, can moment adjust spanner from flow regulator, easily to extract from depositing dedicated lock, the locking of this flow regulator has accused.Any patient or family members, no matter medical personnel are on the scene to be absent from the scene, all cannot realize readjusting and locking precise transfusion flow regulator.Therefore, thoroughly avoided leaving behind transfusion scene medical personnel, because patient or family members tune up transfusion speed voluntarily, caused patient that various infusion reactions occurs, even occurred the serious consequence of patient death.
The assemble method of this precise transfusion flow regulator:
First the lower adjustment disk that spray printing well all identifies and upper adjustment disk separation sleeve being carried out to plug-in type is connected with fixing; And upper adjustment disk, lower adjustment disk with the assembling of flexible gasket therebetween and upper and lower infusion tube and jointing because of all identical with former accurate flow regulator, therefore do not repeat them here; After treating all assemblings, then disk cover is inserted in the upper port of upper adjustment disk, and plug-in mounting puts in place; Last procedure, adjusts dedicated lock spanner to be slightly firmly inserted in the resilient sleeve of upper adjustment disk exactly, arrives this, and " have medical care and specially control the accurate flow regulator of locking conditioning function " all assembling is complete.
The using method of this precise transfusion flow regulator:
There is medical care and specially control the using method of the precise transfusion flow regulator of lock conditioning function, except medical care need change the finger that is held in upper adjustment disk periphery on the handle that is held in dedicated lock tune spanner, have two kinds of operation usings method and function: 1, identical with existing accurate flow regulator, only dedicated lock need be adjusted spanner to pacify all the time solid motionless on the resilient sleeve of accurate flow regulator and the fit structure of joint pin, it is exactly a common accurate flow regulator, anyone (comprising patient and family members) all can be random at any time transfusion speed or the open and close of this flow regulator of adjusting.2, when medical care is in the time completing transfusion speed adjusting, can smoothly easily dedicated lock be adjusted spanner pull up and carry or deposit separately from flow regulator, now, this precision flow regulator can enter lock function, patient or families of patients and other people cannot carry out adjusting privately and the locking of this flow regulator, reach the object of quick infusion.Thereby thoroughly avoid privately tuning up transfusion speed, the serious consequence and the economic loss that cause patient the untoward reaction of transfusion to occur or occur being difficult to prediction, or even dead miserable consequence because of patient or family members and other entourages.In the time that nurse need to readjust transfusion speed, only need adjust spanner to be easily inserted on the resilient sleeve of infusion flow adjuster and the fit structure of joint pin the dedicated lock of carrying, can realize the readjusting and locking of this flow regulator, convenient and practical.
The cost of this precise transfusion flow regulator:
The present invention altogether in two sub-sections.The one, the cost of former accurate flow regulator.The 2nd, the increase part of new function.Because it is only with three assemblies, and three assemblies are in the time of design, and through repeatedly optimizing and compatibility, convenience, practicality and the economy of consideration and existing accurate flow regulator, design experiment goes out the shape of preferred plan and assembly and constructs.And obtain three mould factory professionals' help energetically.Result is not only simple structures, quick for installation of three assemblies, also can realize the production in enormous quantities (mould once can complete the processing and manufacturing of at least 20 parts) of a mould porous, therefore can make the assembly cost newly increasing become being reduced to of multiple minimum (only 0.25 yuan of the manufacturing cost sum of three assemblies), lay a solid foundation to use and the popularization of medical disposable material, also synchronously alleviated patient's expense expenditure.
Positive effect of the present invention:
Long-pending level meaning of the present invention, to guarantee and utilizing under the function of existing accurate flow regulator and the prerequisite of transfusion precision, by design of the present invention, can thoroughly avoid the potential patient of 6-12%, strengthen transfusion speed because privately stealing to regulate, cause the unexpected of various infusion reactions to occur, bring the painful and economic invisible loss of unnecessary health to patient, especially avoid dead unfortunate generation.No matter to patient oneself, or patient's family's wellbeing, or doctors and patients' relation and social harmony, its meaning be all amass grade with great, and cannot weigh with money.This is also as inventor, is again retirement clinical old doctor for many years, and an a white-haired old man, in the limited time in old age, studies true idea and the power producer of this flow regulator with all strength.
