Description
Technical field
The invention belongs to clinical medical transfusion field, particularly there is the precise transfusion flow regulator that lock conditioning function is specially controlled in medical care.
Background technology
Formed primarily of upper adjustment disk, lower adjustment disk and the flexible gasket (generally selecting silica gel material manufacture) be clipped between two dishes by the widely used precise transfusion flow regulator in clinical transfusion field at present, upper and lower two adjustment disk coaxial rotatings connect.Upper and lower adjustment disk is respectively equipped with inlet opening and liquid outlet, flexible gasket is provided with liquid pass hole, be provided with liquid stream road between two adjustment disks, cross the inlet opening on the upper and lower adjustment disk of liquid flow passage and liquid outlet, crossing liquid stream road is variable section structure.The concrete shape crossing liquid stream road has multiple, and such as application number is: 01270179.3, and name is called: the patent of invention of infusion flow adjuster, and what disclose the descending annular groove shape gradually changed of a kind of sectional area crosses liquid stream road; Application number is: 99219623.X, and name is called the patent of invention of flow regulator, discloses the liquid stream road excessively etc. of a kind of one week cutting shape from deep to shallow.Be equipped with infusion tube jointing with holes in the position of the liquid outlet of the position of the inlet opening of upper adjustment disk and lower adjustment disk, two jointings are connected with the infusion tube at two ends respectively.Be provided with joint pin at the center of lower adjustment disk, consider from the sealing of moulding process, connection with the stability angle be connected, joint pin, with certain tapering, is designed with cannelure in joint pin upper end.Upper adjustment disk is designed with the plug-in opening matched with joint pin, is designed with resilient sleeve in the upper end of plug-in opening, resilient sleeve is made up of the multiple flexure strips circumferentially arranged, the upper end medial surface of each flexure strip is equipped with self-locking tooth.When assembling, self-locking tooth is embedded in the cannelure of joint pin, and then realizes assembling and the locking vertically of upper and lower adjustment disk.In addition, at the lateral surface of lower adjustment disk near being provided with the position that upper adjustment disk is combined the multiple scale markers along the circumferential direction arranged, each scale marker is made up of graduation mark and milliliter numerical value, and the lateral surface of upper adjustment disk is designed with sign, usually represents with arrow.When upper and lower adjustment disk centrally relatively rotates, can change the size of amount of infusion, concrete transfusion ml vol can be determined by the scale marker corresponding to arrow.Hold upper and lower adjustment disk for ease of nurse and carry out Flow-rate adjustment, also on the lateral surface of upper and lower adjustment disk, the anti-skidding projection of circumferentially arranging can be set away from both faying face positions.Above-mentioned two adjustment disks are once injection moulding structure.
This precise transfusion flow regulator has 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, cause liquid to input the disadvantage strengthened suddenly.This precise transfusion flow regulator is a kind of flow regulator having very much using value.
And the disadvantage that this precise transfusion flow regulator exists, be that not there is the locking and regulatory function that medical personnel specially control.And be some specialized factory, want for many years to solve but the difficult problem that could not solve.Its consequence causes doctor and patient all arbitrarily can regulate input flow rate.And in the clinical transfusion of reality, through investigation, about have patient or the families of patients of 6-12% (outpatient is more), always think to complete as early as possible transfusion, medical personnel can be carried, steal and tune up transfusion speed.And most medicinal liquid is according to the character of medicinal liquid and points for attention, all can clearly accuse can not be defeated too fast, such as Folium Digitalis Purpureae is exactly definitely can not be soon defeated, and no person is just in peril of one's life.(even if such as Patients with Cardiac Failure is normal saline defeated, once too fast to also have a lot of disease, also heart infarction and pulmonary edema can be inspired), be need the strict medicinal liquid that controls to drip speed, namely no person there will be serious infusion reaction, and individual other even can pay dead cost.Through statistics, this phenomenon privately tuning up transfusion speed, has the gesture of risings year by year, traces it to its cause as follows: 1, because of the development of market economy and deep, causes the life of people, work, the quickening of study rhythm and the anxiety of time and not enough.Impelling some because being pressed for time, being difficult to ensure longer infusion process and time, and blindly privately tune up transfusion speed.2, along with the universal of medical knowledge and raising, people are made to be provided with preliminary understanding to medical science, but pole is unprofessional, be in state of having half knowledge at most, take for quickening transfusion speed and there is no risk, but not knowing because privately tuning up transfusion speed, bringing 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 patient privately tune up transfusion speed majority can not absolutely there is serious infusion reaction, but once there is serious infusion reaction, even cause death, as long as so once, concerning patient and patient family, that is definitely the massive losses of 100%.And thisly privately tune up the infusion reaction that transfusion speed causes because of patient, often say, monthly, the potential patient of annual about the 6-12% all in various places, light or heavy occurs.This superficial by mistake knowing becomes invisible killer.Too increase the misunderstanding between doctors and patients and dispute simultaneously, make medical personnel while physical ability is paid, also will pay the strike of spirit.Because after patient tunes up transfusion speed, once there is serious consequence, some patients 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 be born by medical personnel and swallow humiliation and bear a heavy load.3, due to the enhancing of medical care both sides legal consciousness, the distrust of both sides is deepened, and makes medical personnel when medication is with transfusion, in certain circumstances.Make some patient create 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 decide, and privately steals to tune up transfusion speed.4, some patient tunes up transfusion speed first time and does not cause uncomfortable reaction (majority is because disease is lighter, single amount of infusion is less, the reasons such as medicinal liquid is not only safe but also gentle), regard omnipotent experience, cause creating Double Dare, no matter be what medicine of what disease, private is adjusted and is accelerated to drip speed all without exception, finally probably can lead to serious consequence later.

This precise transfusion flow regulator is on the basis of former delicate flow actuator, do not changing original Chief structure, under not changing the original function of former delicate flow actuator and the prerequisite of transfusion precision, only pass through the not only simple but also cheap accessory of increase by three, and the former non-key position of delicate flow actuator is improved a little, and make flow regulator be provided with new function, achieve new innovation and creation.
Three accessories are connected with the concrete of existing structure and specifically act as:
1, upper adjustment disk separation sleeve: hold between the circumference line of anti-skidding protruding block and the circumference line of transfusion graduation mark at the cylindrical of lower adjustment disk and be designed with a circle seam 22 (see Fig. 3), 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 the object privately tuning up transfusion speed cannot be realized.On upper adjustment disk, lower adjustment disk spray printing after due mark and scale, can by this transparent upper adjustment disk separation sleeve and the first luggage of lower adjustment disk solid, carry out assemble with upper adjustment disk and flexible gasket more afterwards and lock.Why design like this, because tool has the following advantages: 1) in the application, under with the delicate flow actuator of transparent separation sleeve, in guarantee, patient cannot touch the prerequisite of the outer peripheral face of adjustment disk, also can see the whole mark on actuator and scale clearly clearly, be convenient to carry out Flow-rate adjustment accurately and conveniently.2) this kind of design, has just carried out improving slightly at the outer peripheral face of lower adjustment disk and upper adjustment disk, does not do any change, thus can not affect the precision of this flow regulator to the essence structure of upper and lower adjustment disk.3) come upper adjustment disk insulation blocking as lower adjustment disk being directly injected into one extended type; also patient can be made cannot to 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, the difficult problem cannot moving back mould must be there is.Therefore have employed 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 preventing from patient from utilizing the interaction of the fit structure of infusion tube jointing and resilient sleeve and joint pin being formed, in realization, the mutual rotation of adjustment disk and lower adjustment disk, reaches the object privately tuning up transfusion speed.This disk cover is disposable injection molding molding structure.
3, dedicated lock adjusts spanner: dedicated lock adjusts spanner to be connected with the resilient sleeve in former precise transfusion flow regulator by the bellmouth be located on sleeve, and and is provided with concavo-convex plug-in mounting fit structure between resilient sleeve.This structure takes full advantage of the engagement formation of existing resilient sleeve and joint pin, is do not destroying the once successful ingehious design under original structure prerequisite.Because dedicated lock adjusts spanner and existing structure to adopt cone match, existing Quick fastening lock function, there is again plug laborsaving timesaving feature.Adopt this kind of cone match project organization, dedicated lock can be thoroughly avoided to adjust spanner in certain vibrations link of assembling, stock, transport, carrying, mutually depart from delicate flow actuator, cause when clinical transfusion, the dedicated lock come off need adjust spanner to be inserted on delicate flow actuator by nurse again, causes the increase of waste of time and operation sequence.This dedicated lock adjusts spanner usable intensity good macromolecular material (such as ABS engineering plastics) once injection moulding.
This precise transfusion flow regulator is in the starting stage of design, just meet four standard-requireds of flow regulator through repeatedly research and experiment: 1) by the too small restriction of transfusion environment and space, the volume of this actuator can not significantly more than the volume of former actuator.2) gross weight by transfusion device limits, and the weight of this actuator can not significantly more than the weight of former actuator.3) by the time restriction need raced against time during emergency call salving patient, this actuator is more convenient in use operation, better more fast.4) modulated device is the restriction of medical disposable material, and the design and manufaction cost of this actuator is more low better.Therefore, under guarantee meets the prerequisite of above-mentioned 4 standard-requireds, through the continuous failure of 3 years, finally succeed in developing and there is the precise transfusion flow regulator that lock conditioning function is specially controlled in medical care.This actuator regulates while medicinal liquid infusion drips speed medical personnel, synchronously can realize the locking to this actuator.This precise transfusion flow regulator by repeatedly studying for many years, manufacture experimently and realize.This precise transfusion flow regulator by inserting solid upper adjustment disk separation sleeve on lower adjustment disk, insert the solid disk cover in upper adjustment disk upper port and dedicated lock and adjust spanner to realize the adjustment of this actuator, unlatching and lock function.Dedicated lock adjusts spanner to have extremely strong motility, both can insert connection fast, and can be extracted easily again, and be carried with by medical personnel, therefore is called that medical care dedicated lock adjusts spanner.In clinical transfusion, as long as medical personnel are after regulating amount of infusion, under the prerequisite of not changing hands, spanner can be adjusted by dedicated lock instantaneously easily to extract from flow regulator from depositing, and namely the locking of this flow regulator has accused.Any patient or family members, no matter medical personnel are on the scene is absent from the scene, and all cannot realize readjusting and locking precise transfusion flow regulator.Therefore, thoroughly avoid after medical personnel leave transfusion scene, because patient or family members tune up transfusion speed voluntarily, cause patient that various infusion reactions occurs, even occur 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 being carried out plug-in type with upper adjustment disk separation sleeve is connected with fixing; And the assembling of upper adjustment disk, lower adjustment disk and flexible gasket therebetween and upper and lower infusion tube and jointing is because of all identical with former delicate flow actuator, 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 " having the delicate flow actuator that lock conditioning function is specially controlled in medical care " namely all assembling is complete.
The using method of this precise transfusion flow regulator:
There is the using method that the precise transfusion flow regulator of lock conditioning function is specially controlled in medical care, except the finger being held in upper adjustment disk periphery need change except on the handle being held in dedicated lock tune spanner by medical care, have two kinds of operation usings method and function: 1, identical with existing delicate flow actuator, only dedicated lock need be adjusted spanner to pacify all the time solid motionless in the resilient sleeve of delicate flow actuator and the fit structure of joint pin, it is exactly a common delicate flow actuator, anyone (comprising patient and family members) all can be random at any time the transfusion speed of this flow regulator of adjustment or open and close.2, when medical care is while completing transfusion speed adjustment, spanner can be adjusted by dedicated lock smoothly easily to pull up from flow regulator and carry with or deposit separately, now, this delicate flow actuator can enter lock function, patient or families of patients and other people cannot carry out adjustment privately and the locking of this flow regulator, reach the object of quick infusion.Thus thoroughly avoid because patient or family members and other entourages tune up transfusion speed privately, the untoward reaction causing patient to occur to infuse or occur the serious consequence that is difficult to predict and economic loss, or even the tragic consequence of death.When nurse needs to readjust transfusion speed, only need spanner be adjusted easily to be inserted on the resilient sleeve of infusion flow adjuster and the fit structure of joint pin the dedicated lock carried with, readjusting and locking this flow regulator can be realized, convenient and practical.
The cost of this precise transfusion flow regulator:
The present invention altogether in two sub-sections.One is the cost of former delicate flow actuator.Two is increase parts of New function.Because it is only with three assemblies, and three assemblies are when design, and through repeatedly optimizing and considering and the compatibility of existing delicate flow actuator, convenience, practicality and economy, design experiment goes out the shape design of preferred plan and assembly.And obtain the help energetically of three mould factory professionals.Result is three assemblies not only simple structures, quick for installation, 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 the assembly cost newly increased can be made to become being reduced to of multiple minimum (the manufacturing cost sum of three assemblies only 0.25 yuan), lay a solid foundation to the use of medical disposable material and popularization, also synchronously alleviate the expense expenditure of patient.
Positive effect of the present invention:
Long-pending level meaning of the present invention, ensureing and utilizing the function of existing delicate flow actuator with under the prerequisite of precision of infusing, by design of the present invention, thoroughly can avoid the potential patient of 6-12%, because privately stealing adjustment increasing transfusion speed, cause the accident of various infusion reaction to occur, bring unnecessarily physical pain and economic invisible loss to patient, especially avoid dead misfortune to occur.No matter to patient oneself, or patient's family's wellbeing, or the harmony of the relation of doctors and patients and society, its meaning be all long-pending level with great, and cannot to weigh with money.This is also namely as inventor, and be again retirement clinical old doctor for many years, 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.
