Abstract
The utility model relates to an ampoule of a needleless injector, which belongs to the technical field of medical equipment and comprises a casing of a sleeve-shaped structure. The ampoule of the needleless injector is characterized in that a core rod is arranged in the casing, the structure of the core rod is matched with the structure of a cavity of the casing, and a nozzle is arranged at the top end of the core rod. The ampoule of the needleless injector removes a piston. By means of the core rod with the structure matched with that of the cavity of the casing of the ampoule, the core rod outer wall and the casing inner wall can tightly attach to each other to complete injection when the ampoule of the needleless injector is used, thereby guaranteeing tightness between the core rod and the cavity of the casing, ensuring the injection to be safe and hygienic and reducing production cost.
Description
Technical field
This utility model relates to a kind of needleless injector ampoule, belongs to technical field of medical instruments.
Background technology
At present, when traditional needleless injector was carried out the medicine injection, the needleless injector injector promoted the ampoule core bar, produces pressure medicinal liquid is injected through the ejection of ampoule front end nozzle.For guaranteeing the adaptation requirement of needleless injector ampoule, require supporting piston on core bar.That piston might occur is unholiness, microgranule and foreign body etc., if cooperates with core bar and closely not throw off, influence is injected in inhaling the medicine process; And owing to the existence of piston, increased the production cost of equipment, increased the waste of resource.
The utility model content
According to above deficiency of the prior art, the technical problem that this utility model will solve is: a kind of above-mentioned defective that solved is provided, has guaranteed adaptation, practiced thrift cost, guaranteed the needleless injector ampoule of injection safety health.
This utility model solves the technical scheme that its technical problem adopted: described needleless injector ampoule; The housing that comprises pipe box shape structure; It is characterized in that: be provided with core bar in the housing, the structure of the structure of core bar and housing inner chamber adapts, and the core bar top is provided with nozzle.
The principle of this utility model is: the principle that can reach sealing according to the surface tension of liquid surface existence with in little matched in clearance; When two fit clearances are between 0.005-0.01; Because the surface tension between the liquid surface molecule exists, and can reach sealing effectiveness between two mating surfaces.
The structure of the structure of core bar and housing inner chamber adapts, and core bar outer wall and inner walls is fitted tightly accomplish injection.
The beneficial effect that this utility model had is: the needleless injector ampoule has been cancelled piston; The core bar that adapts through the structure that adopts with the housing inner chamber of ampoule; Core bar outer wall and inner walls are fitted tightly accomplish injection; Guaranteed the adaptation of core bar and housing inner chamber, guaranteed the safety and sanitation of injection, and reduced production cost.
Description of drawings
Fig. 1 is the structural representation of this utility model.
