Description

Make up a prescription transfusion system
Technical field
Make up a prescription transfusion system the present invention relates to one kind, it is especially a kind of to prepare or take be installed in air-tight bottle or The transfusion system that makes up a prescription of drug toxicity and toxic gas in hermetic bag.
Background technique
Some drugs have toxicity, such as the chemotherapeutics for the treatment of cancer.In order to reduce medical staff's contact toxicity drug Risk, these drug toxicities closing transfer become critically important, the used outer surface for exempting from needle connector can not have one The drug toxicity residual of point point, can not allow the toxic gas containing drug toxicity to drift in exterior space, otherwise medical care people Member inadvertently contacts drug toxicity, will affect nervous system, damages reproductive system, and increase the risk for suffering from leukemia.
The existing transfusion system that makes up a prescription includes an ontology and one exempts from needle connector, can be used for taking two kinds of medicine and dosing etc. with On the way.
When user wants to take out drug toxicity from an air-tight bottle or a hermetic bag, firstly, needle connector connection will be exempted from One syringe or be connected to closing type joint that one connects with syringe or be connected to one connect with syringe special set Then the active type closed joint of meter elapses a piston to the most inner side of syringe, to empty the air in syringe. Then, with the transfusion system that makes up a prescription in lower and air-tight bottle or hermetic bag upper for principle, the puncture portion of ontology poke air-tight bottle or The sealing of hermetic bag.Then, piston is pulled from the inside of syringe toward external, so that the toxicity medicine in air-tight bottle or hermetic bag Object by the transfusion system that makes up a prescription, is then injected into inside syringe from top to down, to complete correctly medicine to be taken to act.
However, during taking medicine, because being added in air-tight bottle or hermetic bag without clean gas, toxicity medicine Object is difficult to extract out from air-tight bottle or hermetic bag.
In dosing, some drug toxicities are before use, first must dissolve or dilute, so must be by syringe from one Drug toxicity is extracted out in a container.Then, the needle connector of exempting from of the existing transfusion system that makes up a prescription connects syringe or is connected to The closing type joint that connects with syringe or the active type closed joint for being connected to the special designing to connect with syringe.So Afterwards, with the transfusion system that makes up a prescription in upper and air-tight bottle or hermetic bag lower for principle, a puncture portion of ontology poke air-tight bottle or The sealing of hermetic bag.Finally, the drug toxicity in syringe to be pushed to the connecting pin by syringe from top to down using piston Conduit or closing type joint or active type closed joint so that drug toxicity is from top to down by the transfusion system that makes up a prescription, It is then injected into air-tight bottle or hermetic bag, to complete correct dosing movement.
However, working as drug toxicity because the material of air-tight bottle is usually the material that glass etc. is hard and will not deform When injecting air-tight bottle, the atmospheric pressure in air-tight bottle can be greater than extraneous atmospheric pressure, if needle connection is exempted from syringe disengaging at this time Device, then the gas in air-tight bottle can be by exempting from needle connector pressure release, so that some toxic drug in air-tight bottle can be with gas shape Formula or by atomizing type by exempting from needle connector, cause drug toxicity to be easy to remain in the outer surface for exempting from needle connector, Toxic gas containing drug toxicity also can cause exterior space by exempting from needle connector dissipation.At this point, the skin of medical staff can It can touch drug toxicity, it is also possible to toxic gas be sucked in lung, nervous system is influenced, damage reproductive system, and increase Add the risk for suffering from leukemia.
In this regard, have one kind make up a prescription transfusion system include a balloon, balloon be set to ontology side.
During taking medicine, firstly, elapsing piston to the most inner side of syringe, to by the clean sky in syringe Gas, which is pushed, enters balloon by ontology, so that balloon includes cleaned air, while the cleaned air emptying in syringe.In toxicity While inside infusion of medicine syringe, since the atmospheric pressure in air-tight bottle or hermetic bag is less than extraneous atmospheric pressure, institute To allow the cleaned air in balloon to maintain sealing subsequently into air-tight bottle or hermetic bag by the transfusion system that makes up a prescription to reach Atmospheric pressure effect identical with extraneous atmospheric pressure in bottle or hermetic bag, while drug toxicity is easy to be from air-tight bottle or close It is extracted out in envelope.
During dosing, the toxic gas in air-tight bottle can enter in balloon, to achieve the effect that pressure release, so that close The atmospheric pressure sealed in bottle or hermetic bag remains identical as the external world, avoids some toxic drug in air-tight bottle or hermetic bag can be with Gas form or by atomizing type by exempting from needle connector, therefore will not toxic medicament residue in the appearance for exempting from needle connector Face, toxic gas will not be drifted and exempting from needle connector in exterior space.Therefore, the skin of medical staff will not touch Drug toxicity will not suck toxic gas in lung.
Through above-mentioned correct dosing and prescription formula is taken, drug toxicity will not be entered in balloon by ontology.
Only, some lack ideas medical staff, in dosing, the transfusion system that can will make up a prescription be arranged under, air-tight bottle or The setting of person's hermetic bag causes the drug toxicity injected in air-tight bottle or hermetic bag to be easy to flow by ontology from top to bottom upper In balloon.
There are also one kind transfusion systems that makes up a prescription to further include a non-return valve, and non-return valve is set to ontology
During taking medicine, firstly, elapsing piston to the most inner side of syringe, to by the clean sky in syringe Gas emptying.While inside drug toxicity injection syringe, since the atmospheric pressure in air-tight bottle or hermetic bag is less than the external world Atmospheric pressure, so directly allowing cleaned air from exterior space by the transfusion system that makes up a prescription, subsequently into air-tight bottle or sealing In bag, the effect identical with extraneous atmospheric pressure of the atmospheric pressure in air-tight bottle or hermetic bag is maintained to reach, while toxicity Drug is easy to extract out from air-tight bottle or hermetic bag.
During dosing, the toxic gas in air-tight bottle can pass through non-return valve and enter in balloon, to reach pressure release Effect avoids the part in air-tight bottle or hermetic bag so that the atmospheric pressure in air-tight bottle or hermetic bag remains identical as the external world Drug toxicity can in gaseous form or by atomizing type by exempting from needle connector, therefore will not toxic medicament residue in exempting from needle The outer surface of connector, toxic gas will not be drifted and exempting from needle connector in exterior space.Therefore, the skin of medical staff Skin will not touch drug toxicity, will not suck toxic gas in lung.
But such transfusion system that makes up a prescription can not still prevent mistake dosing method when, drug toxicity flow into balloon in The problem of.More and, non-return valve has that structure is complicated, volume is big, at high cost and the problems such as be easily damaged.
Come again, is taking or preparing avirulent drug sometimes, whether there is or not balloons not to affect operation.But above-mentioned two The balloon of the existing transfusion system that makes up a prescription of kind is that cementation is non-removable on the body, so user can not be according to its meaning Will, balloon of dismantling are inconvenient with taking or preparing avirulent drug.
