Abstract
The invention discloses a kind of multifunctional injector, including syringe needle, injection needle tube and injection ram, syringe needle setting is arranged in injection needle tube in injection needle tube front end, injection ram；It further include syringe pump, obstruction detector and alarm device.Multifunctional injector of the present invention is structurally reasonable, has the characteristics that prevent blocking, using safe, is suitble to promote and apply.
Description
Technical field
The invention belongs to the field of medical instrument technology, are related to a kind of multifunctional injector.
Background technique
With change of people life style and sex culture idea, and western exploitation, the increase of floating population etc., plum
Malicious patient is also in increasing trend year by year, not only increases the financial burden of patient, influences its physically and mentally healthy and family harmony, while right
Other people and offspring also result in great harm, or even increase social unstable factor.What ministry of Health of China in November, 2011 was announced
Epidemic data show that for the disease incidence of syphilis in the trend that rises year by year, syphilis has been more than that stranguria syndrome is passed as the most common property
Broadcast disease.
Tardocillin is that treatment syphilis generally acknowledged at present is cheap, choice drug of special efficacy, slow release after intramuscular injection
And be absorbed, effective blood concentration maintains to be up to one week.It is before use plus suitable according to the requirement on tardocillin medication instruction book
The physiological saline or water for injection of amount are at suspension, deep intramuscular injection.The medicine is penicillin dibenzyl ethylenediamine salt and appropriate
Buffer and the aseptic powdery that is mixed of suspension, be suspension after dissolution.The suspension formed after tardocillin dissolution
Liquid particle is big, belongs to coarse dispersion system, has very big surface free energy, has self-assemble to be inclined to and increase and tends to, and in weight
Easily occur to precipitate under power effect and coalesce and cannot disperse, especially ion surface charges, and syringe needle enters muscle heat 1-2 seconds
There is solidification phenomenon.The researchs such as Chen Ruhong report that the long axis of the acicular crystal of tardocillin is longer, are easily gathered into pencil, mix
Outstanding property is poor, forms biggish particle and particle diameter distribution is uneven, easily cause syringe needle blocking.Li Hua research report tardocillin dissolution
There is precipitated and separated phenomenon within static 10 seconds afterwards, extracts 15 seconds motionless i.e. blocking syringe needles after medical fluid is vented with syringe.In view of benzyl
These characteristics of star penicillin, traditional injecting method easily occur medical fluid in syringe needle precipitating, solidification, blocking, cause injection failure.
To prevent syringe needle from blocking when conventional injection, injection operation personnel often quickly push away medicine, and medical fluid rises the pressure of local organization suddenly
Height will increase patient pain's degree, or even because of firmly excessive easy cause syringe and syringe needle disengagement, cause medical fluid splash waste etc..
Farhadi A assessment tardocillin pain level be it is serious, reach VAS score 7.4/10.Few patients are because fearing injection
Pain and refuse or midway stop injection treatment etc. whens have been reported that.This phenomenon is puzzled vast nursery work person for a long time.It is right both at home and abroad
The correlative study of tardocillin injecting method also emerges one after another, and such as mitigates pain with lidocaine is solvent, but have induction
The risk of arrhythmia cordis, even allergy, limits and is widely used, by changing position and injection site, or even increase solvent
Or changing the methods of solvent to have been reported that when mitigating the research of pain also, useful syringe needle reserves air method or takes out more needle exchange after medicine
Syringe needle blocks during the protective inoculations such as head method (empty needle head), the former causes uncertain to human body latent because air enters human body
In danger, the latter causes the increase etc. of material consumption, therefore how not satisfactory effect is.Clinically more typically apply large size syringe needle
(No. 9 or more) carry out injection prevention syringe needle blocking, but because syringe needle is thicker, tissue damage is also big, and patient's inserting needle pain is obvious.
Summary of the invention
Blocking is prevented, using safe multifunctional injector the purpose of the present invention is to provide a kind of.
Itself the specific technical proposal is:
A kind of multifunctional injector, including syringe needle, injection needle tube, injection ram, syringe press hand and syringe
Holding handle, syringe needle setting are arranged in injection needle tube in injection needle tube front end, injection ram；It further include syringe
Pump, obstruction detector and alarm device.
It further, further include injection needle tube installation site detection device, for judging whether syringe is mounted on corresponding slot
Position, including syringe detection lug, spring, fixing seat and optoelectronic switch.
It further, further include the anti-siphon means in syringe holding handle, for preventing and treating medical fluid since siphon is existing
As leading to flow out, including push rod tabletting, gear, rack gear and direct current generator.
The utility model has the advantages that
Multifunctional injector of the present invention is structurally reasonable, has the characteristics that prevent blocking, using safe, is suitble to promote and apply.
Detailed description of the invention
Fig. 1 is the schematic diagram of multifunctional injector of the present invention.
Specific embodiment
Technical solution of the present invention is described in more detail in the following with reference to the drawings and specific embodiments.
Referring to Fig.1, a kind of multifunctional injector, including syringe needle 1, injection needle tube 2, injection ram 3, syringe are pressed
Hand 4 and syringe holding handle 5, the setting of syringe needle 1 are arranged in 2 front end of injection needle tube, injection ram 3 in injection needle tube 2
It is interior；It further include syringe pump 6, obstruction detector 7 and alarm device 8.
It further include injection needle tube installation site detection device, for judging whether syringe is mounted on corresponding slot position, including
Syringe detection lug, spring, fixing seat and optoelectronic switch.
It further include the anti-siphon means in syringe holding handle, for preventing and treating medical fluid since siphonage causes to flow
Out, including push rod tabletting, gear, rack gear and direct current generator.
Multifunctional injector of the invention in the specific application process, is detected by injection needle tube installation site detection device
Whether syringe is installed in place；If injector syringe is not mounted in corresponding slot, the signal that syringe is installed in place is not triggered,
Alarm device can prompt operator, correctly be installed, and avoid because of harm caused by installation site mistake；Anti-siphon means can
To prevent medical fluid caused by siphonage from flowing out；If obstruction detector detects abnormal phenomenon, alarm device in injection process
Also alarm can be issued, adverse consequences is avoided.
The foregoing is only a preferred embodiment of the present invention, the scope of protection of the present invention is not limited to this, it is any ripe
Know those skilled in the art within the technical scope of the present disclosure, the letter for the technical solution that can be become apparent to
Altered or equivalence replacement are fallen within the protection scope of the present invention.
