Abstract
The utility model discloses a disposable medicine feeding device for infusion, which is composed of an expansion cavity, the insertion end and the liquid medicine sucking end of an infusion bottle. A filtering net is arranged in the expansion cavity; needle heads and moving valve gates are all arranged on the insertion end and the liquid medicine sucking end, and needle sheaths are sheathed on the needle heads. The utility model is that liquid medicine is sucked by negative pressure generated by squeezing the expansion cavity and siphon action and directly enters the infusion bottle, an operating program and pollution opportunities are reduced, and cost is lower. The utility model is suitable for clinical mass use.
Description
This utility model relates to a kind of therapeutic medical disposable infusion drug feeding device.
Venous transfusion is one of route of administration of using always of treatment patient.During venous transfusion, often need to add some drugs in infusion bottle, i.e. preparating liquid.At present, each hospital method commonly used is to use the glass syringe preparation, promptly earlier the required medicinal liquid that adds is pumped into syringe, in the infusion bottle that reinjects.Sometimes for avoiding pharmaceutical incompatibility and cross infection in hospital, one can only add a kind of medicine to syringe, if need to add multiple medicine, and then need be with many syringe.But often there is following shortcoming in the method for above-mentioned preparating liquid: one is to use the articles for use of disposable glass syringe, causes a large amount of wastes of material, increases patient's financial burden, and increases the hospital supply room workload; Two when being to use glass syringe to take out medicine, easily pollutes piston and cause cross infection in hospital; The 3rd, repeated localised puncture infusion bottle rubber closure during dosing increases opportunities for contamination, and the chance that the rubber closure microgranule enters infusion bottle also increases.
The purpose of this utility model is to provide a kind of disposable infusion drug feeding device, to overcome above-mentioned shortcoming.
For achieving the above object, this utility model disposable infusion drug feeding device is made up of swollen chamber, infusion bottle insertion end and aspiration medicinal liquid end, and swollen intracavity is provided with drainage screen; Infusion bottle insertion end, aspiration medicinal liquid end all are equipped with syringe needle and mobile valve; Be set with needle shield on the syringe needle.
When adopting the disposable infusion drug feeding device preparating liquid of said structure, owing to be directly to enter infusion bottle by negative pressure and siphonage aspiration medicinal liquid that the swollen chamber of extruding drug feeding device produces, reduced operation sequence, but continuous sucking medicinal liquid and rubber closure that needn't the repeated localised puncture infusion bottle again, reduce opportunities for contamination, and cost is lower, is applicable to clinical a large amount of use.
Below in conjunction with the drawings and specific embodiments this utility model disposable infusion drug feeding device is described in further detail.
Fig. 1 is the structural representation of this utility model disposable infusion drug feeding device.
Shown in Figure 1, this utility model disposable infusion drug feeding device is made up of swollen chamber (1), infusion bottle insertion end (2) and aspiration medicinal liquid end (3).Having with the milliliter on the swollen chamber (1) is the graduation mark of unit, and its shape can be garden cylindricality or ellipse garden shape, and is unrestricted, in a drainage screen (4) is housed, be used for filtering liquid medicine and airborne impurity.Infusion bottle insertion end (2) is equipped with syringe needle (5), mobile valve (6), and syringe needle (5) connects with joint (7) with insertion end (2).Aspiration medicinal liquid end (3) is equipped with syringe needle (8), mobile valve (9), and natural torsion is 45--90 ° of arc, syringe needle (8) with take out medicine end (2) and connect with joint (10).Be with needle shield (11), (12) on syringe needle (5), (8) respectively.The material that above-mentioned disposable infusion drug feeding device is adopted is a vinyon.
During use, take out the disposable infusion drug feeding device, take out needle shield (11), (12), allow mobile valve (6), (9) be in open state, syringe needle (5) is inserted in the infusion bottle, with the hands shape that fists, extrude the interior gas in swollen chamber (1), make it to produce negative pressure, simultaneously syringe needle (8) is placed under the ampoule giving drugs into nose liquid level, loose one's grip, because siphonage enters in the infusion bottle ampoule inner liquid medicine rapidly.
Claims (1)
