Abstract
The utility model provides a bottle plug puncture device, which comprises a needle tube and a needle seat, wherein the lower end of the needle tube is equipped with a side hole, the side hole is communicated with the lower end portion of the needle tube and the needle seat, the needle seat is communicated with an infusion tube or/and an air inlet tube, one or more cavities which are independent with the infusion tube or/and the air inlet tube are arranged in the upper end portion of the needle tube, and the cavities are communicated with the outer portion through one or a plurality of channels. When a big infusion plastic bottle with a medicine cavity or an infusion soft bag with a medicine charge interface is punctured, a part of the cavity of the needle tube is filled by medicine, at the moment, the upper end portion of the needle tube is communicated with liquid medicine in the medicine charge cavity and the plastic bottle, the liquid medicine in the big infusion plastic bottle or the infusion soft bag and the medicine in the medicine charge cavity can be fully mixed through rotating an angle and shaking, the whole puncture device is punctured in place after mixing, and the process of puncturing and mixing the medicine is completed at the moment.
Description
Technical field
This utility model relates to disposable infusion set, is specially the bottle plug puncture unit of disposable infusion set.
Background technology
Disposable infusion set is mainly used in the patient is carried out vein conveying medicinal liquid usefulness, and bottle plug puncture unit is the vitals on the transfusion device.At present, the inventor has developed a kind of large plastic bottle for transfusion that has the medicine chamber, or has the transfusion flexible bag of medicine interface, accomplish the medicine of medicine intracavity is mixed with the medicinal liquid in large plastic bottle for transfusion or the transfusion flexible bag, then need to improve the structure of bottle plug puncture unit, reach the purpose of mixing medicine.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide the bottle plug puncture unit that mixes the medicine problem in a kind of simple in structure, large plastic bottle for transfusion that can solve band medicine chamber or the transfusion flexible bag.
For achieving the above object, be achieved through the following technical solutions:
Bottle plug puncture unit, include needle tubing and needle stand, the bottom of needle tubing has side opening, side opening is communicated with needle tubing bottom and needle stand, needle stand with tube for transfusion or/and air inlet pipe be connected, it is characterized in that: described needle tubing upper end is built-in with one or more and is independent of tube for transfusion or/and the cavity of air inlet pipe, and cavity is by one or several passages and be communicated with outward.
Described needle tubing bottom diameter increases the screens structure of resistance greater than needle tubing upper end diameter when forming puncture.
Adopt the bottle plug puncture unit of said structure, the bottom of needle tubing has side opening, and side opening is communicated with needle tubing bottom and needle stand, as the air inlet of bottle plug puncture unit or/and infusion port, needle stand with air inlet or/and infusion pipeline be connected.Be provided with independently cavity in the upper end of needle tubing, cavity is communicated with the passage of needle tubing upper end, when puncture has the large plastic bottle for transfusion in medicine chamber or has the transfusion flexible bag of medicine filling mouthpiece, the cavity of needle tubing partly can be filled by medicine, at this moment, the upper end of needle tubing is communicated with powder charge chamber and plastic bottle inner liquid medicine, rotational angle and vibration are rocked and the medicine of medicinal liquid in large plastic bottle for transfusion or the transfusion flexible bag and powder charge intracavity fully can be mixed, again whole perforator puncture is put in place after mixing, this moment, puncture and mixed medicine process were finished, simple and convenience very, and avoid causing the pollution that produces in the mixed medicine process.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 position profile of the present utility model.
The specific embodiment
As shown in Figure 1, 2, bottle plug puncture unit, include needle tubing 1 and needle stand 2, the bottom of needle tubing 1 has side opening 3, side opening 3 is communicated with needle tubing 1 bottom and needle stand 2, or/and air inlet pipe 5 is connected, described needle tubing 1 upper end is built-in with one or more and is independent of tube for transfusion or/and the cavity 4 of air inlet pipe 5 needle stand 2 with tube for transfusion, and cavity 4 is by one or several passages 6 and be communicated with outward.Needle tubing 1 bottom diameter increases the screens structure 7 of resistance greater than needle tubing 1 upper end diameter when forming puncture.
When puncture has the large plastic bottle for transfusion in medicine chamber or has the transfusion flexible bag of medicine filling mouthpiece, cavity 4 parts of needle tubing 1 can be filled by medicine, at this moment, the upper end of needle tubing 1 is communicated with powder charge chamber and plastic bottle inner liquid medicine, rotational angle and vibration are rocked and the medicine of medicinal liquid in large plastic bottle for transfusion or the transfusion flexible bag and powder charge intracavity fully can be mixed, again whole perforator puncture is put in place after mixing, this moment, puncture and mixed medicine process were finished, simple and convenience very, and avoid causing the pollution that produces in the mixed medicine process.
