Soft bag with dual-needle medicament feeder

Technical field

The present invention relates to a kind of medical apparatus and instruments, relate in particular to a kind of soft bag with dual-needle medicament feeder that is connected, easily realizes the medicament mixed interior with medicament reservoir with medicament reservoir.

Background technology

For the medicine by in medicament reservoir adds in the solution in infusion vessel, then mixed solution is inputted such as the patient in the Clinical Institutions of hospital.

The existing mode that medicine in medicament reservoir and the solution in infusion vessel are mixed mainly contains following several:

One, adopt disposable syringe: at first, use disposable syringe by in the input of the solution in infusion vessel medicament reservoir, then, also use this disposable syringe that mixed solution is moved in solution container.Because of without other device, therefore in the Clinical Institutions of hospital, usually use this kind mode, but may infiltrate impurity and complicated operation.

Two, adopt the container that connection instrument such as double ended meedle or connecting tube will be equipped with dissolved substance to connect with the container that solution is housed.Make the container lean of dissolved substance is housed so that the medicine that is dissolved in container is injected in the container that solution is housed.Yet aforesaid operations is complicated and time-consuming.Particularly when the operation of beating on the container that carries out containing medicine in air for the hole that connects, the contaminated probability of the medicine that is equipped with increases.

Three, in order to solve the problem that exists in above-mentioned two kinds of modes, developed a kind of medicine bottle of injection, in this medicine bottle, be equipped with as the capsule of the bottle of medicament reservoir by a pipe with infusion vessel solution, that have the liquid medicine outlet be housed be connected.In this pipe, towards bottle, be connected with the pin of a hollow, towards infusion vessel, be connected with occluding material, the pipe that for example is made of plastics.Occluding material blocks passage in pipe to prevent liquid flow.While using this medicine bottle, the bottle in expulsion bladder, and pass rubber closure so that be connected with infusion vessel with the pin of hollow.Use finger to break occluding material to reopen the passage in pipe, thereby medicine and solution are mixed.

Four, with respect to the further improved medicine bottle of the medicine bottle of above-mentioned injection, comprise: with the infusion vessel of fluid passage, top at infusion vessel has a lid, solution or dilute solution are housed in the medicine bottle of injection, the capsule that is connected with this infusion vessel, the medicament reservoir that is connected with pin by passing the rubber stopper that seals import, and this medicament reservoir remains in capsule, and the runner pipe device that is connected with the inboard of medicament reservoir for the inboard by infusion vessel.In addition, this runner pipe device comprises: the cavity pin of hollow, the centre of this pin has a center, and at two ends, have needle point, use continuously a needle point of cavity pin to pass the stopper of medicament reservoir and use another needle point of cavity pin to pass the control device of lid so that infusion vessel is connected with medicament reservoir of infusion vessel.The improvement of the medicine bottle of this injection is: medicament reservoir is connected with the infusion vessel that solution is housed, but uses the pin of hollow pass the rubber closure of medicine bottle and use finger to break a plurality of action need long time of occluding material.In addition, when occluding material is not destroyed fully, solution can occur and be difficult to by passage, and need the problem of many time dissolvings.
