Abstract
The utility model provides an antipollution drug dispensing device, relating to the technical field of medical machinery. The antipollution drug dispensing device comprises a syringe barrel, a syringe needle, a syringe barrel cover, two finger rings, a telescopic type sleeve, a squeezing plate, a supporting spring, a syringe pin and a piston. The antipollution drug dispensing device is characterized in that the syringe needle is sheathed and arranged fixedly on a connecting pipe on the front end of the syringe barrel; the syringe barrel cover is connected onto the rear end of the syringe barrel in a thread way; the two mutually-symmetric finger rings are fixedly connected onto the outer wall of the syringe barrel ahead of the syringe barrel cover; the telescopic type sleeve is connected onto the syringe barrel cover in a seal way; the upper end of the telescopic type sleeve is connected with the squeezing plate in the seal way; the upper end of the syringe pin in the telescopic type sleeve is fixedly connected with the squeezing plate after passing through the supporting spring between the syringe barrel cover and the squeezing plate; and the lower end of the syringe pin in the telescopic type sleeve is fixedly connected with the piston in the syringe barrel after passing through a center hole in the cover face of the syringe barrel cover. The antipollution drug dispensing device is simple in structure and convenient to operate; as the syringe pin is located in the telescopic type sleeve, the syringe pin can be prevented from being polluted; and therefore, the potential safety hazard caused by pollution is thoroughly prevented and the medical safety of a patient is guaranteed.
Description
Technical field: this utility model relates to technical field of medical instruments, specifically a kind of anti-pollution dispenser.
Background technology: at present, medical personnel are the syringes that adopts existing 20ml or 50ml when preparing the transfusion medicament to the patient mostly.During use, extract out with the medicinal liquid that syringe will be pacified in the bottle, or reinject after with the medicinal liquid suction in the powder medicine bottle with syringe, treat with syringe medicinal liquid to be extracted out and is filled in the large transfusion bottle again after the medicine powder dissolving just to infuse to the patient.In the aforesaid operations process, medical personnel often repeated multiple times use an identical medicament of syringe preparation, therefore are easy to pollute the pintle of syringe, antibacterial is brought in the syringe, thereby cause liquid medicine contamination.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy and simple to handle, can prevent the anti-pollution dispenser that pintle is polluted.
The purpose of this utility model is achieved in that this anti-pollution dispenser comprises syringe, syringe needle, syringe lid, finger ring, telescopic sleeve, stripper plate, support spring, pintle, piston, suit is being fixed syringe needle in the adapter of syringe front end, the syringe that is being threaded above back end of syringe lid, fixedly connected two symmetrical finger rings on the syringe outer wall of syringe lid front; Syringe covers face seal and is connecting telescopic sleeve, the telescopic sleeve upper end is tightly connected with stripper plate, pintle upper end in the telescopic sleeve is fixedly linked with stripper plate after passing support spring between syringe lid and the stripper plate, the lower end pass behind the syringe lid cover center hole with syringe in piston be fixedly linked.
During use, forefinger and middle finger are inserted finger ring, can finish injecting and aspirating of medicinal liquid with the continuously extruded and loosening stripper plate of thumb.
Advantage of the present utility model: simple in structure, easy and simple to handle, because pintle is in the telescopic sleeve, can avoid pintle to be polluted, thoroughly stopped to pollute the potential safety hazard that causes, guaranteed patient's medical safety.
Description of drawings: Fig. 1 is structure cutaway view of the present utility model.
The specific embodiment: describe in further detail below in conjunction with this utility model of Fig. 1: this anti-pollution dispenser comprises syringe 1, syringe needle 2, syringe lid 3, finger ring 4, telescopic sleeve 5, stripper plate 6, support spring 7, pintle 8, piston 9, suit is being fixed syringe needle 2 in the adapter of syringe 1 front end, the syringe that is being threaded above syringe 1 rear end lid 3, syringe cover fixedly connected two symmetrical finger rings 4 on syringe 1 outer wall of 3 fronts; Telescopic sleeve 5 is being tightly connected above the syringe lid 3, telescopic sleeve 5 upper ends and stripper plate 6 are tightly connected, pintle 8 upper ends in the telescopic sleeve 5 are passed syringe lid 3 and are fixedly linked with stripper plate 6 with support spring 7 backs between the stripper plate 6, and the lower end is passed syringe and covered behind the 3 cover center holes with the interior piston 9 of syringe 1 and be fixedly linked.
