Abstract

The utility model relates to a medical instrument which can be used as an injection medicine container and can also be used to inject medicine to human body. The medical instrument is composed of an ampoule body, a metallic needle and a sealing cap. The type of the ampoule body can be a powder injection type and a liquid type. The capacity scope of the ampoule body is 1 milliliter to 50 milliliter. The ampoule body is suitable for various medicament injection and intravenous injection. Compared with the present ampoules and injectors used in general hospitals, the utility model has the advantages of simple manufacturing process and low cost. After being sterilized for one time and sealed in a plastic bag, the period of validity of the medical instrument can reach two years. The utility model is suitable for any environment and places, in particular for remote areas, medical stations with poor medical condition or battleground aid.

Description

Ampoule injector

This utility model belongs to the medicament reservoir medicine of holding concurrently and is injected into a kind of medical apparatus and instruments of human body.

Medical injection ampoule and traditional cartridge syringe, majority is separately assembling and uses at present.Body acupuncture agent of injection ampoule separatory and injectable powder, liquid injection ampoule, general body is the garden cylindricality, cervical region is a taper, the injectable powder ampoule, majority is the garden cylindricality, with Jiao Gaifengkou and kalamein thin slice.Traditional syringe has glass syringe, or disposable plastic injector, is by having graduated needle tubing, needle tubing core, syringe needle composition.

Above-mentioned injection ampoule and syringe, the manufacturing process complexity, the cost height needs high-pressure disinfection equipment and long scalding in the use.For the syringe clinical practice, need be with needle tubing, nook closing member, syringe needle is existing assembles, aspiration medicinal liquid will seal taper with the emery wheel cut and gets rid of, could the sucking-off medicinal liquid; The application of powder ampoule needs bottleneck metallic film breakdown is punctured Jiao Gai, injects normal saline, is mixed with medicinal liquid, could inject.These operation sequences are numerous and diverse, and not only work efficiency is low, and cause cross infection easily.

This utility model purpose is, in order to overcome the defective that above-mentioned ampoule and syringe exist, develop a kind of simple in structure, handling ease, cost is low, the novel ampoule syringe that clinical manipulation is easy reaches the environment for use that enlarges the ampoule syringe simultaneously.

This utility model is by ampoule body (1), cervical region (2), and metal needle (3), solid sealing cap (4) constitutes.Ampoule body (1), can be injectable powder shape and liquid shape, be garden shape or flat, with scale, there is a jack (2 ') at cervical region (2) center to body on one's body, and metal needle (3) inserts in the cervical region (2) by jack (2 '), fixed through injection moulding, metal needle (3) exposes the termination, with solid sealing cap (4) sealing, prevents overflow of drug fluid.

On the bottom of the ampoule body of injectable powder shape (1) or the close sidewall of bottom, a nipple (5) that leads to ampoule body (1) intracavity is arranged, the outer hollow seal medicated cap (6) that wears of nipple (5).

Ampoule syringe range of capacity is 1～50 milliliter, ampoule syringe as used for intravenous injection, its formation is on injectable powder ampoule syringe basis, adorn the sleeve pipe (7) of a rigid plastics or metal in the jack (2 ') on the cervical region (2), sleeve pipe (a 7) exposed parts cover flexible plastic conduit (8), conduit (8) end connects a scalp acupuncture (9), and the syringe needle end is sealed with solid sealing cap (4).

Below in conjunction with description of drawings.

Fig. 1 is a liquid shape ampoule syringe assembling sketch map, also is one of this utility model case study on implementation.

Ampoule body (1) is the garden cylindricality, the bottom is a taper, cervical region (2) is the garden cylindricality, metal needle (3) is by jack (2 ') and cervical region (2), add in injection moulding and to be combined as a whole man-hour, the root of metal needle (3) stretches into 1～2 millimeter of ampoule body (1) intracavity, be with a sealing cap (4) on needle point, it is made with plastics or elastomeric material.

The ampoule syringe, the medicine of packing into, seal, through after the sterilization, the good seal in the plastic bag of packing into is in order to using.As long as open plastic bag during use, pull out the sealing cap (4) on the metal needle point, just can inject.

Fig. 2 is a powder ampoule syringe assembling sketch map, is two of this utility model case study on implementation.

Formation is on Fig. 1 basis, and there is a nipple (5) that communicates with ampoule body (1) inner chamber ampoule body (1) bottom, a sealing cap of nipple overcoat (6).

Fig. 3 is another assembling sketch map of ampoule syringe, is three of this utility model case study on implementation.

Formation is on Fig. 2 basis, in the centre bore (2 ') of cervical region (2), a plastic conduit or medical metal pipe (7) are housed, in the injection moulding course of processing, itself and cervical region (2) are fixed together, pipe (7) exposed parts is with soft conduit (8), and the terminal scalp acupuncture (9) that connects of conduit (8) seals with sealing cap (4) on the scalp acupuncture.

The ampoule body (1) of above-mentioned all size ampoule syringe, cervical region (2), nipple (5), hollow seal medicated cap (6) all uses non-toxic plastic injection molded.

The utility model, simple in structure, more original ampoule and syringe, manufacturing process is simple, and cost is low, behind once sterilizing, uses plastic bag sealing, can remain valid 2 years phases. Be adapted at any environment and place and use, particularly to the isolated area, the medical station of medical condition difference or military first aid are used, and be more convenient.
