Abstract
A kind of anti-pollution dispenser, relate to technical field of medical instrument, it comprises syringe, piercing needle, seal cover, finger ring, rustless steel piston, strong magnetic iron hoop, it is characterized in that syringe front end is connected with piercing needle, rear end thread seal is connected to the seal cover that capping outer wall is provided with finger ring, and the syringe near seal cover is provided with the air-vent communicated with its inner chamber; Syringe internal slide is tightly connected the rustless steel piston adapted with its internal diameter, and syringe slide outside cover is filled with the strong magnetic iron hoop corresponding with rustless steel piston, strong magnetic iron hoop outer wall is provided with annular and refers to groove.Move by the magnetic attraction of strong magnetic iron hoop owing to being sealed in the rustless steel piston in syringe, therefore when preparing transfusion medicament to patient, the hands of operator can not touch syringe inwall and rustless steel piston, antibacterial can be avoided to enter syringe inside, prevent medicinal liquid from being polluted.
Description
Technical field: this utility model relates to technical field of medical instrument, specifically a kind of anti-pollution dispenser.
Background technology: at present, medical personnel are when preparing transfusion medicament to patient, adopt the syringe of existing 20ml or 50ml to carry out pump drainage repeatedly mostly, when pulling pintle to carry out pump drainage medicinal liquid, the hands of operator is easy to touch pintle, pintle is polluted, and antibacterial is brought in syringe causes liquid medicine contamination.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of when preparing transfusion medicament to patient, can prevent the anti-pollution dispenser that medicinal liquid is polluted.
The purpose of this utility model is achieved in that this anti-pollution dispenser comprises syringe, piercing needle, seal cover, finger ring, rustless steel piston, strong magnetic iron hoop, syringe front end is connected with piercing needle, rear end thread seal is connected to the seal cover that capping outer wall is provided with finger ring, and the syringe near seal cover is provided with the air-vent communicated with its inner chamber; Syringe internal slide is tightly connected the rustless steel piston adapted with its internal diameter, and syringe slide outside cover is filled with the strong magnetic iron hoop corresponding with rustless steel piston, strong magnetic iron hoop outer wall is provided with annular and refers to groove.
During use, one holds finger ring, and another hands pinches strong magnetic iron hoop and moves axially, and strong magnetic iron hoop can drive rustless steel piston move forward in syringe or retreat, thus the row completing medicinal liquid takes out.
Advantage of the present utility model: move by the magnetic attraction of strong magnetic iron hoop owing to being sealed in the rustless steel piston in syringe, therefore when preparing transfusion medicament to patient, the hands of operator can not touch syringe inwall and rustless steel piston, antibacterial can be avoided to enter syringe inside, prevent medicinal liquid from being polluted.
Accompanying drawing illustrates: Fig. 1 is structure sectional view of the present utility model.
Detailed description of the invention: this utility model is described in further detail below in conjunction with Fig. 1: this anti-pollution dispenser comprises syringe 1, piercing needle 2, seal cover 3, finger ring 4, rustless steel piston 5, strong magnetic iron hoop 6, syringe 1 front end is connected with piercing needle 2, rear end thread seal is connected to the seal cover 3 that capping outer wall is provided with finger ring 4, and the syringe 1 near seal cover 3 is provided with the air-vent communicated with its inner chamber; Syringe 1 internal slide is tightly connected the rustless steel piston 5 adapted with its internal diameter, and syringe 1 slide outside cover is filled with the strong magnetic iron hoop 6 corresponding with rustless steel piston 5, strong magnetic iron hoop 6 outer wall is provided with annular and refers to groove.
Neodymium-iron-boron iron hoop selected by strong magnetic iron hoop 6, and the cross section of strong magnetic iron hoop 6 is greater than the cross section of rustless steel piston 5, magnetic due to ndfeb magnet surmounts the magnetic of ferrite magnet, aluminum nickel cobalt, SmCo greatly, ndfeb magnet can adsorb the weight of weight 640 times own, and therefore strong magnetic iron hoop 6 can drive rustless steel piston 5 to move by magnetic force easily.
