Description

The sealed crosspointer drug feeding device of air bag release of pressure overall process

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to the sealed crosspointer drug feeding device of a kind of overall process.

Background technology

For the medicine in the cillin bottle is added in the solution in the infusion vessel, then mixed solution is imported such as the patient in the clinical mechanism of hospital.

At present medicine in the cillin bottle and the solution in the infusion vessel are carried out blended mode and mainly contain following several kinds: one, employing disposable syringe.Two, adopt the container that fastening means such as crosspointer or connection tube will be equipped with dissolved substance to be connected with the container that solution is housed.Three, a kind of medicine bottle of injection, in this medicine bottle, be equipped with as the capsule of the bottle of cillin bottle through a pipe with infusion vessel solution, that have the liquid medicine outlet be housed be connected.In this pipe, be connected with the pin of a hollow, be connected with occluding material towards infusion vessel towards bottle.When using this medicine bottle, the bottle in the expulsion bladder, and pass rubber closure so that be connected with infusion vessel with the pin of hollow.Use finger to break occluding material opening the passage in the pipe again, thereby make medicine and solution mixing.Above-mentioned three kinds of dosing methods can't realize that all the integral asepsis state connects.And closed drug feeding device described in the prior art all can only be implemented in and mix the airtight of medicine process, and can not realize cillin bottle and dosing pin dock, mix medicine and " overall process is sterile closed " when infusing.

Mix medicine in order to realize that cillin bottle and infusion vessel are connected fully under aseptic condition; In the prior art, also have and adopt sealing bag, cillin bottle, drug feeding device and infusion vessel are packaged in the sealing bag under aseptic condition; When needing to mix medicine; Directly in sealing bag, promote cillin bottle, be communicated with cillin bottle and infusion vessel, be implemented in mixed medicine under the aseptic condition through drug feeding device.This employing sealing bag is realized the mode of aseptic chemical mixing, when mixing medicine, the iris action of sealing bag is arranged, and it is inconvenient to promote cillin bottle, and cost is also higher.

The utility model content

To the above-mentioned deficiency that exists in the prior art, this utility model provides a kind of cillin bottle can under the integral asepsis state, dock with infusion vessel, has mixed medicine and transfusion, and simpler, the lower-cost sealed crosspointer drug feeding device of air bag release of pressure overall process of structure.

In order to solve the problems of the technologies described above, this utility model has adopted following technical scheme: the sealed crosspointer drug feeding device of air bag release of pressure overall process, comprise crosspointer, interior cover and be enclosed within the overcoat that puts; The cross section of inboard wall of cover is provided with the crosspointer elastic supporting seat in said, and said crosspointer elastic supporting seat is provided with a through hole along the axis of interior cover, and the pin base fastener of said crosspointer is provided with two rows along the sealing ring that circumferentially is provided with on the outer wall of interior cover in through hole; The draw-in groove that the one end sealing of said overcoat, the inwall of its external sleeve are provided with the circumferential setting at least one row edge and are used with the interior seal ring seal that puts; On the sealed end of the outer wall of interior cover or overcoat, be provided with interior cover in the air bag that communicates.

As a kind of preferred version of this utility model, the draw-in groove that the inwall of its external sleeve is provided with the circumferential setting in two row edges and is used with the interior seal ring seal that puts.

As the another kind of preferred version of this utility model, said in an end of cover be and the link of the interface seam of infusion vessel that the other end is the end that is inserted in of overcoat; The inwall of said link is provided with female thread.

This utility model beneficial effect is: when using the sealed crosspointer drug feeding device of this air bag release of pressure overall process; Only need interior cover seam on infusion vessel; Cillin bottle is put into cover under aseptic condition, and put in overcoat is enclosed within, promote overcoat; Make going up on row's sealing ring that outer next row's draw-in groove that puts puts in being stuck in, whole drug feeding device is in sealing state at this moment; When mixing medicine, continue to promote overcoat, on next the row's sealing ring that makes that outer next row's draw-in groove that puts puts in being stuck in, put in the process of promotion in being enclosed within outward, air bag increases along with the pressure in the interior cover and outwards expands gradually, plays the pressure in the cover in discharging; Meanwhile; Crosspointer moves down, and the needle point of crosspointer pierces through the sealing-plug in cillin bottle and the infusion vessel, realizes that cillin bottle is connected with the state of infusion vessel at integral asepsis; Thereby medicine is mixed through once contacting of short time with solution; Real realize cillin bottle and drug feeding device dock, mix medicine and transfusion the time " overall process is sterile closed ", not only use more convenient, and this crosspointer drug feeding device structure more simply, cost is lower.
