Abstract
The utility model discloses a self-destruction disposable direct injection ampoule which belongs to a medical injection device. The utility model includes an injection syringe, an ampoule body and a piston. An annular groove is arranged on the ampoule body and a leaf spring base is arranged on the external walls of the annular groove. Compressible and evaginable leaf springs are arranged along the circumference of the leaf spring base. A holding groove is arranged on the tail of the injection syringe, and the size of the grab handle inner hole is bigger than or equal to the inside diameter of the injection syringe. The design of the grab handle inner hole bigger than or equal to the inside diameter of the injection syringe is to ensure the free movement of the ampoule body inside the injection syringe. The design of holding groove structure and the compressible and evaginable leaf springs inside the annular groove forms a self-destruction structure to ensure the device a one-off one and the self-destruction disposable direct injection ampoule can work with even force to avoid pain and injures to the patient. The piston is initially close to the front end of the injection syringe internal walls to avoid aging in long time storage and leakage of drugs to ensure the application of the direct injection ampoule.

Summary of the invention
The purpose of this utility model is the defective at above-mentioned prior art, provides a kind of rational in infrastructure, easy and simple to handle, and use firmly evenly can not form Disposable, self-destroying and direct injection type ampoule painful and injury to the patient.
The technical scheme taked of this utility model is to achieve these goals: a kind of Disposable, self-destroying and direct injection type ampoule, comprise injection tube, ampoule body, piston, the ampoule body front end is provided with piston rear end and is provided with handle, described ampoule body is provided with annular groove, be fastened with around the outer wall at the groove two ends at close handle place and lock tooth shell fragment base and isolate the shell fragment base, edge lock tooth shell fragment base circumferencial direction and isolation shell fragment base circumferencial direction are provided with the collapsible lock tooth shell fragment that turns up and isolate shell fragment; The injection tube afterbody is provided with horn mouth, and handrail and horn mouth form draw-in groove, and hole dimension is more than or equal to the injection tube internal diameter size in the handrail; Isolate the shell fragment end and be positioned at the outside, lock tooth shell fragment end.
Be fastened with restriction shell fragment base around the groove one end outer wall near described piston place, be provided with the collapsible restriction shell fragment that turns up along restriction shell fragment base circumferencial direction.
Described restriction shell fragment, lock tooth shell fragment and isolation shell fragment respectively are four, and uniform along shell fragment base circumferencial direction.
Described piston is provided with otch, and otch forms 40-50 degree oblique angle with the piston-top surface of close injection tube inwall.
The beneficial effects of the utility model are: adopt the interior hole dimension of handrail more than or equal to the injection tube internal diameter size, guaranteed the freely-movable of ampoule body in injection tube; The self-distruction structure of the collapsible shell fragment composition that turns up is set in employing draw-in groove structure and the groove, makes the direct injection ampoule firmly evenly can not form misery and the disposable that injures and guaranteed it to the patient in use; The piston original state is close to the injection tube front inner wall, has prevented long storage time because wearing out of the rubber piston that the medicinal liquid seepage causes guaranteed the use of direct injection ampoule.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As Fig. 1-shown in Figure 5, a kind of Disposable, self-destroying and direct injection type ampoule comprises injection tube 5, ampoule body 6, piston 8, and ampoule body 6 front ends are provided with piston 8, the rear end is provided with handle 1.Flow out for the ease of medicinal liquid, described piston 8 is provided with otch 9, and otch 9 forms 40-50 degree oblique angle with piston 8 end faces of close injection tube 5 inwalls.Described ampoule body 6 is provided with annular groove 4.Be fastened with restriction shell fragment base 13 around the groove 4 one end outer walls near piston 8 places, be provided with the collapsible restriction shell fragment 7 that turns up along restriction shell fragment base 13 circumferencial directions.Be fastened with around the outer wall at groove 4 two ends at close handle 1 place and lock tooth shell fragment base 14 and isolate shell fragment base 15, edge lock tooth shell fragment base 14 circumferencial directions and isolation shell fragment base 15 circumferencial directions are provided with the collapsible lock tooth shell fragment 10 that turns up and isolate shell fragment 12; Isolate shell fragment 12 ends and be positioned at the outside, lock tooth shell fragment 10 ends.Described restriction shell fragment 7, lock tooth shell fragment 10 and isolation shell fragment 12 respectively are four, and uniform along shell fragment base circumferencial direction.Injection tube 5 afterbodys are provided with horn mouth 3, and handrail 2 forms draw-in groove 11 with horn mouth 3, and hole dimension is more than or equal to injection tube 5 internal diameter sizes in the handrail 2.
The user mode of this utility model Disposable, self-destroying and direct injection type ampoule:
1) uses preceding original state: as shown in Figure 1, be with rubber pin medicated cap on the syringe needle, the ampoule body 6 that medicinal liquid is equipped with in inside is arranged in the injection tube 5, and the piston 8 of ampoule body 6 front ends is close to injection tube 5 front inner wall, isolates shell fragment 12 ends as shown in Figure 3 and is positioned at the outside, lock tooth shell fragment 10 ends.
User mode when 2) extracting ampoule body out: syringe needle is twitched ampoule body handle 1 downwards, piston 8, shell fragment are with ampoule body 6 motions at this moment, because syringe needle is inserted in the rubber pin medicated cap and is blocked state, injection tube 5 front ends are negative pressure state, the effect of medicinal liquid gravity in addition, piston otch 9 is opened to the syringe needle direction, and medicinal liquid is inhaled in the injection tube 5.Ampoule body 6 is twitched to injection tube 5 handrails 2 places, and positive stop spring plate 7 snaps in the draw-in groove 11 as shown in Figure 4, and ampoule body 6 can not continue to extract out, comes off when having prevented ampoule body 6 outer drawing effectively.Isolate shell fragment 12 and turn up, lock tooth shell fragment 10 exposes automatically.
