Description
Technical field
The present invention relates to a kind of novel medical drug delivery system, especially a kind of net type inner septum two-chamber transfusion device of drop.
Technical background
Currently, well known disposable medical infusion apparatus is mainly used for venous transfusion, by aseptic process, establish vein with
The common medical disposable material in channel between medical fluid.Generally adjusted by intravenous needle, helmet, infusion tube, liquid medicine filter, flow velocity
Device, drop pot, bottle plug puncture unit, air inlet pipe air filter, infusion bottle or infusion bag connecting structure composition.The principle of medical infusion
It is to utilize: mainly gravity (terrestrial gravitation), under pressure (atmospheric pressure) conditioning of auxiliary, makes transfusion liquid by eminence freedom
The principle fallen is completed as human body to by medicine infusion process.Due to being directly used in the pharmaceutical technology of the infusion medicine of human administration
Complicated higher cost, for a long time, traditional infusion device construction and the deficiency in design cause the later period in infusion stream drop process,
Drug can not be given completely by medicine human body, remain in infusion apparatus system Chinese medicine liquid and be simply discarded, be long-term in medical system
The problem of the phenomenon that being widely present, it directly brings is: 1, human body is short of by medicine；2, the waste of resource medicine and fund is caused；
3, make pharmacy corporation, HealthCare Enterprise and the common people increase invisible burden, and the waste cumulative amount of generation is huge, this problem
It is long-term ignored.
In view of the above-mentioned problems, applicant is once improved, a kind of infusion is proposed in 201611050138 .8 of ZL
The net type medical Transfusion device of the defeated drop of capsule built in bottle or infusion bag, by traditional infusion bottle or infusion bag, one table of compound implantation
Face is evenly distributed with the plastic bag or spherical capsule of pin hole.Infusion bottle or infusion bag inject base fluid in production, meanwhile, PVC plastic
Assist naturally in capsule or spherical capsule full of base fluid, medical treatment is in use, before infusion stream drips and terminates, at this point, infusion bottle or defeated
Liquid bag will empty, and wherein the base fluid of PVC plastic capsule or spherical capsule seeps drop into infusion bottle from reserved pin hole under the action of negative pressure
Or in infusion bag and infusion tube, the seepage discharge of base fluid is suitble to infusion stream drop amount, and the stream in the case where connecting stream drop effect drips process, makes
Medical fluid in infusion apparatus system, infusion tube is rinsed well by the completely defeated drop of base fluid, and finally remaining in infusion tube is PVC
Plastic bag or the subsequent base fluid of spherical capsule.Above scheme can solve the problem of infusion apparatus system Chinese medicine liquid residual, but simultaneously,
Have the disadvantage in that first, plastic bag or spherical capsule need compound implantation, and complex process is difficult to control product quality；Second, it answers
With there is certain limitation, when being only applicable to the injection base fluids such as glucose injection or normal saline solution, use when production
The case where drug is added, but be not suitable for injecting the use situation of full medical fluid when production.Therefore, it still needs to be further improved.
Summary of the invention
The object of the present invention is to provide a kind of net type inner septum two-chamber transfusion device of drop, can prevent defeated at the end of infusion process
The residue problem of liquid applicator system Chinese medicine liquid, and further overcome complex process, product quality not easy to control, application range limitation
The problems such as.
In order to solve the problems existing in the prior art, the present invention provides a kind of net type inner septum two-chamber transfusion device of drop, including defeated
Liquid bottle or infusion bag, which is characterized in that be compounded with inner septum in infusion bottle or infusion bag, will be separated into inside bottle body or bag body big
Multiple micropores are distributed on the inner septum in two cavitys of chamber and small chamber.
Preferably, the material of the infusion bottle is polyethylene or polypropylene, the material of the infusion bag be polyvinyl chloride or
Non-PVC composite membrane.
Preferably, the inner septum extends to bottle body from the bottom of infusion bottle bottle body or bag body of infusion bag to central region and opens
Mouth or bag body opening.
Preferably, the inner septum and bottle body are open or the lid of bag body opening is fitted close, and lid is divided into
Two parts, in order to respectively toward big chamber and small intracavitary insertion syringe or perfusion tube.
Preferably, the inner septum is flexible material.
Preferably, the inner septum is identical as infusion bottle or infusion bag material.
Preferably, the micropore is distributed on inner septum close to the area of infusion bottle bottle body opening or bag body of infusion bag opening
Domain prevents small intracavitary base fluid from entering too early big intracavitary.
Preferably, the diameter of the micropore is 0.15mm-1.2mm, preferably 0.2mm-0.6mm.
Preferably, in production, in the big chamber and small intracavitary injection base fluid, or only in the big intracavitary full medicine of injection
Liquid.
Preferably, the base fluid is normal saline solution, glucose injection or Dextrose and Sodium Chloride Inj..
The present invention drips the characteristics of net type inner septum two-chamber transfusion device and beneficial effect is:
1, while abiding by traditional infusion operating process and regulation, easily and effectively medical fluid can be given completely by medicine human body,
Structure is simple.
2, it has wide range of applications, is applicable not only to inject the bases such as glucose injection or normal saline solution when production
The case where drug is added when liquid, use, while being also applied for injecting the use situation of full medical fluid when production.
The first situation: the base fluids such as glucose injection or normal saline solution are injected when production.Medical use starts,
At this point, the big chamber injection to infusion bag or infusion bottle, infusion bag and infusion bottle internal pressure are in barotropic equilibrium state, at this point, greatly
Chamber medical fluid and small chamber base fluid, do not generate exchange, to reach only immixture.
Second situation: in production, only to big chamber into injecting full medical fluid, full medical fluid refers to the medical fluid that is mixed with prepared
Base fluid, the small chamber in two-chamber are not necessarily to injection, since the material of inner septum is flexible material, at this point, inner septum can stick on bottle body
Or in bag body, so that small chamber is blank state.Medical treatment is in use, only to the small intracavitary carry out fluid injection in two-chamber；It is complete in big chamber
Medical fluid is without reinjecting base fluid.
Medical treatment in use, infusion process back segment, medical fluid in infusion bag or infusion bottle i.e. by defeated drop to the greatest extent, infusion bag and
For infusion bottle under the action of gravity and atmospheric pressure external force, infusion bag or infusion bottle internal pressure are unbalance, vacuum state are in, at this point, chamber
Condition of negative pressure is generated in vivo, and under the action of condition of negative pressure, small intracavitary base fluid, which connects, seeps drop discharge, connects to the big chamber medical fluid of leading portion
Continue continuous fluid infusion process so that secondary effectively rinse infusion apparatus system to liquid, this continuously connect to liquid
In the process, the flushing to medical fluid in infusion apparatus system is realized.
4, easy and safe to operate, reduce manual intervention, avoids fault caused by occurring because of manual operation.
5, structural integrity is combined, and improves reliability, simplifies preparation process, reduces production cost.
