Abstract

The utility model discloses a syringe ampoule with drug, which belongs to an ampoule for injecting or a medical syringe. A butyl colloidal piston which can be screwed with a propelling rod is arranged on the rear end of a glass syringe needle tube, a necking ring groove which is arranged on a nipple root of the front end is covered by a stopper after clamped by a screw sleeve, and an enclosed ampoule structure which can store physic liquor is formed. The stopper is removed during the use, a needle bolt of screw connection is provided with a wing-shaped convex needle, and the utility model can be clinically used. Physic liquor can not be polluted, and the needle can not be pulled out when viscous physic liquor is injected. The use shows that the utility model can obtain satisfactory effects.

Description

Band medicine injection ampoule

This utility model relates to ampoule and particularly a kind of band medicine of the injector for medical purpose injection ampoule that is used to inject.

At present the syringe that uses clinically is generally glass syringe and disposable plastic injector, will store the medicine Ampoule neck during use earlier and fracture and extract medicinal liquid again.The ampoule glass chip falls into medicinal liquid and brings and damage in addition that medicinal liquid is exposed to air in the operation, and complicated operation easily causes pollution, and the big syringe needle of pressure easily comes off when particularly injecting the thickness medicinal liquid, the big inefficiency of medical worker's labor intensity.

Chinese patent 95 2 29338.2 adopts the double-decker of establishing glass inner tube in the plastics injection tube, to solve the chemical reaction problem of storage medicine process herb liquid and working of plastics.

Chinese patent CN 2116480 U disclose the sleeve of its likeness in form syringe of a kind of ampoule, and the bottom is that piston blocks by the pressure conducting piece, supply the grafting push rod for the depression bayonet socket at the bottom of the piston.It is syringe nipple that the bottle front end is narrowed to bottleneck, and its periphery is with fixed overcoat, and the nearly bottleneck end of the latter has female thread, deviates from order to anti-its of fixed needle.Overcoat far-end and bottleneck end have interrupted score, make overcoat and bottleneck frangibility or open.Though this technology is integrated ampoule and syringe sleeve, interior powder charge liquid but still when unavoidably fractureing bottleneck chip fall in the medicinal liquid.And garden taper overcoat internal thread machining difficulty is big, and fracture easily injured user when syringe needle was installed in the back that fractures.

It is that two slices watts of shape syringe shells connect together by two concentric shafts that Chinese patent CN 2197069 Y disclose a kind of vertical open-close type syringe, and piston female thread and push rod external screw thread in it spin.

The purpose of this utility model is exactly in order to provide a kind of medicinal liquid that is suitable for to store, to be difficult for polluting, the band medicine injection ampoule that injection thickness medicinal liquid syringe needle can not be deviate from.

This utility model is by following conceptual design.

Taper nipple root at glass needle tubing front end is provided with the necking down annular groove, is the plastics swivel nut in elastic center hole for the clamping bottom, and the pintle that can be spirally connected in the swivel nut has the protruding syringe needle of wing; Top central authorities hung and establish that ligule protrudes into and obstruction that shutoff Taper Pipe, perisporium contain nipple in the taper nipple can be added a cover, and the glass syringe rear end makes needle tubing form the storage medicine ampoule structure of sealing after inserting piston.

The necking down annular groove of nipple is pre-installed swivel nut before using, and inserts the piston of butyl rubber system in the glass needle tubing, and behind the perfusion solution, nipple is added a cover the storage medicine ampoule structure that the gelationus obstruction of butyl closely cooperates needle tubing formation is sealed.Piston spiral shell dress pushing ram takes off obstruction during use, and spiral shell dress pintle has the protruding syringe needle of wing, can be for the usefulness of clinical injection medicinal liquid.

She Ji band medicine injection ampoule is pre-installed medicinal liquid in the needle tubing of glass material like this, two ends are respectively with the piston of butyl rubber system with stop up shutoff, constitute the ampoule structure, but because the swivel nut spiral shell of clamping dress pintle has the protruding syringe needle of wing, so overcome the drawback that has syringe needle to come off when injecting the thickness medicinal liquid.

Below in conjunction with drawings and Examples it is described this utility model.

Fig. 1 is this utility model storage medicine state vertical profile structural front view.

Fig. 2 installs local vertical profile front view behind the syringe needle for this utility model.

Fig. 3 stops up the vertical profile front view for this utility model.

Fig. 4 is this utility model swivel nut top view and front view.

The front end of band medicine injection ampoule is the taper nipple, inserts the piston 2 of mouth female thread at the bottom of the butyl colloid in the glass needle tubing 1 of collar extension convex edge, rear end, and the pushing ram 3 that can be spirally connected.Taper nipple root is provided with necking down annular groove 4, supplies the clamping bottom to have the swivel nut 6 of centre bore 5, crosses centre bore and has the cross gap, adopts moulding, has elasticity, is convenient to clamp.The taper nipple can be added a cover the Nei Ding center and be hung and establish that ligule is protruding 7, the hollow obstruction 8 of the airtight containing nipple of perisporium, stops up external wall of upper portion strip pod 9 and is beneficial to hand-heldly, takes off obstruction, pintle can be had protruding curved syringe needle 10 spiral shells of wing to be loaded in the swivel nut 6.

The band medicine injection ampoule of making is like this obtained satisfied effect through trying out.

Claims

1. be with the medicine injection ampoule for one kind, comprise the protruding syringe needle of mouth band wing at the bottom of the pintle, front end is the be spirally connected rubber piston of pushing ram of the glass needle tubing of taper nipple, collar extension convex edge, rear end and Qi Nei, it is characterized in that, taper nipple root is provided with the necking down annular groove, for the clamping bottom is the plastics swivel nut in elastic center hole, and the pintle that can be spirally connected in the swivel nut has the protruding syringe needle of wing; Top central authorities hung and establish that ligule protrudes into and obstruction that shutoff Taper Pipe, perisporium contain nipple in the taper nipple can be added a cover, and the glass syringe rear end makes needle tubing form the storage medicine ampoule structure of sealing after inserting piston.
