Description
Technical field
This utility model relates to a kind of transfusion device, belongs to technical field of medical instruments.
Background technology
Transfusion is one of the rescue of commonly using clinically and the important measures for the treatment of patient.Transfusion device forms the infusion channel between human vein and medical liquid container (transfusion bag or infusion bottle), transfusion device comprises intravenous needle, infusion tube, liquid medicine filter, flow regulator, transfusion drip tube (Murphy type burette), bottle plug puncture unit, bottle plug puncture unit is the puncture needle of hollow, puncture needle top is provided with inlet opening, medical liquid container opening is provided with gum elastic sealing-plug, during use, puncture needle, through sealing-plug, makes the inlet opening on puncture needle be positioned at medical liquid container inner chamber.Medicinal liquid in medical liquid container inner chamber is entered transfusion device and is flowed into vein by inlet opening.The flexible fastening that fixedly only depends on the sealing-plug piercing through of puncture needle and medical liquid container opening at present, fixing not firm, puncture needle easily departs from from medical liquid container opening.In order to prevent that puncture needle from departing from from medical liquid container opening, puncture needle often needs to enter the longer distance of sealing-plug, makes inlet opening and sealing-plug top distance longer, and the medicinal liquid in medical liquid container inner chamber is not fully utilized, and causes waste.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of fixed, easy to use transfusion device is provided.
This utility model technical solution is: a kind of transfusion device, comprise bottle plug puncture unit, medical liquid container, medical liquid container is provided with opening, the top of described opening is provided with sealing-plug, the bottom of described opening is provided with female thread, described bottle plug puncture unit comprises the puncture needle of hollow, puncture needle top is provided with inlet opening, puncture needle is provided with fixed plug, fixed plug is positioned at the lower end of inlet opening, the outer wall of fixed plug is provided with external screw thread, described external screw thread and described female thread are suitable, the top of puncture needle is positioned at the inner chamber of medical liquid container through sealing-plug, puncture needle is by the external screw thread of fixed plug, the female thread of opening and the opening of medical liquid container fix.
As improvement, the outer wall of above-mentioned puncture needle is provided with graduation mark, and graduation mark is positioned at the upper end of fixed plug.
The top of above-mentioned graduation mark and puncture needle is 10 millimeters apart from a.
Technique effect of the present utility model is: the bottom of this utility model medical liquid container opening is provided with female thread, the outer wall of puncture needle fixed plug is provided with external screw thread, bottle plug puncture unit and medical liquid container are fixed by screw thread, fixed, prevent that bottle plug puncture unit from coming off, like this puncture needle through sealing-plug, enter the distance of medical liquid container inner chamber can be shorter, the medicinal liquid in medical liquid container inner chamber can be fully used.Outer wall at puncture needle is provided with graduation mark, the top of graduation mark and puncture needle is 10 millimeters apart from a, when puncture needle passes sealing-plug, making graduation mark be positioned at sealing-plug tip edge is advisable, easy to operate, make inlet opening can fully enter medical liquid container inner chamber on the one hand, medicinal liquid is circulated smoothly, also prevent that on the other hand inlet opening is too higher, medicinal liquid is fully used.
