Abstract
The utility model provides a novel invagination type bottle stopper puncture needle. The utility model improves the traditional bottle stopper puncture device, and the opening of an edge hole of a transfusion tube at the needle point part of the bottle stopper puncture device is made into a circular arc-shaped inner groove. The utility model reduces rubber particles to flow into a transfusion bottle, and consequently, adverse effects on patients brought by using the traditional puncture device can be avoided.
Description
This utility model belongs to medical instruments field, is specifically related to the bottle plug puncture unit that uses on the disposable infusion syringe.
At present, many patients tend to take place some untoward reaction after using the disposable infusion syringe, and the serious serious symptoms such as shock that also can take place jeopardizes patient's life.Trace it to its cause, except that the generation problem of transfusion own, it is generally acknowledged to be to use the disposable infusion syringe to cause.After bottle plug puncture unit on the traditional infusion syringe inserted rubber bottle cover, its lateral opening opening part was sharper, is easy to a bottle stopper rubber and slices off, and caused particle, flour rubber to flow into medicinal liquid, polluted the negative effect of medicinal liquid.Though many manufacturers improve the transfusion syringe, as use novel material, increase new passage etc., result of use is also not really desirable.
The purpose of this utility model has been to provide a kind of novel invaginating bottle plug puncture unit, reduces contaminant particles and flows in the transfusion, guarantees patient's life security.
The purpose of this utility model is achieved in that this novel invaginating bottle plug puncture unit improves the traditional stopper perforator, does inner groovy in the arc-shaped to the lateral opening opening part of the tube for transfusion of bottle plug puncture unit needle tip.
Like this, the invaginating bottle plug puncture unit that this utility model provides makes the sharp place of opening directly not contact rubber closure in inserting the rubber bottle cover process, thereby opening is sharp and cause particle rubber microgranule to enter transfusion and the adverse effect brought to patient when having avoided traditional perforator to insert rubber bottle cover.
Below in conjunction with drawings and Examples this utility model is further described.
Fig. 1 is the front view of this utility model invaginating bottle plug puncture unit.
Fig. 2 is the A-A cross section view of this utility model invaginating bottle plug puncture unit.
The invaginating bottle plug puncture unit that this utility model provides is made up of needle point 1, tube for transfusion 2, air inlet pipe 3, support 4, air filter hole 5.Tube for transfusion 2 is positioned at invaginating bottle plug puncture unit inside, it is characterized in that tube for transfusion 2 lateral opening opening parts do inner groovy in the arc-shaped, when inserting rubber bottle cover, make the sharp place of opening directly not contact rubber closure, air inlet pipe 3 is positioned at 1 one at the needle point of invaginating bottle plug puncture unit, link to each other with air filter hole 5, sanitation and hygiene when air filter hole 5 guarantees extraneous air admission infusion bottle, support 4 is positioned at the both sides at invaginating bottle plug puncture unit rear portion, makes bottle plug puncture unit firmly to insert in the infusion bottle smoothly.
This utility model has significantly reduced the generation of contaminant particles when bottle plug puncture unit inserts infusion bottle owing to improved the profile of bottle plug puncture unit, and feasible medical level to patient is significantly improved, and the health level that improves people is contributed.
