Description

ampoule syringe

The present invention relates to an ampoule syringe, and more specifically, to an ampoule syringe that can be used efficiently by slowly discharging the injection liquid injected into the ampoule little by little.

As is well known, an ampoule is a small container containing an injection liquid. These ampoules are hygienic and suitable for heat sterilization because the injection liquid does not come into contact with anything other than the container because the injection liquid is injected into the container through the injection port and then the injection is sealed. There is.

As a prior art related to ampoules, Korea Registered Utility Model No. 20-0447881 (registration date: February 19, 2010) ‘Safe Ampoule for Injection’ has been disclosed.

The prior art is “a safety ampoule for injection comprising a body portion containing a chemical solution, a head portion separated from the body portion, and a narrow cut neck connecting the body portion and the head portion, wherein the safety ampoule has an outer peripheral surface. It is joined to a protective means to cover the cut surface generated when the body portion and the head portion are separated, and is characterized in that a groove of a predetermined depth is formed in an area corresponding to the cut neck portion of the outer peripheral surface of the protective means. “Safe ampoule for injection.” is the gist of the technology.

The above-described prior art has the effect of preventing glass fragments or powder generated during the process of separating the body and head from entering the interior of the body.

However, this prior art has the problem of not being able to be used multiple times because the injection solution must be completed at once with the head separated, and the convenience of use is reduced because a separate syringe is required to inject the injection solution into the tissue. There was a problem that it was difficult to induce rapid absorption.

As a prior art to solve the above problems, Republic of Korea Patent No. 10-2154125 ‘Ampoule Syringe’, previously applied for by the present applicant and registered on September 3, 2020, is disclosed.

Referring to Figure 6, the prior art is an ampoule cartridge 100 having a microneedle 122 that pierces the skin tissue by striking and a micro outlet 123 that finely discharges the injection solution, and the microneedle 122 is drawn out. The housing 200 is formed so that the needle hole 213 is connected to communicate with the operating space 221 and the receiving space 211 for accommodating the ampoule cartridge 100, and is capable of sliding in the operating space 221 of the housing 200.

Included is the gist of the technology.

Here, the micro discharge port 123 of the ampoule cartridge 100 is preferably formed with an inner diameter of 1.0 to 1.2 mm.

For that reason, if the inner diameter (ø) of the micro-discharge port 123 exceeds 1.2 mm, a large amount of injection liquid contained in the ampoule cartridge is discharged at once and is not completely absorbed into the hole in the skin tissue formed by the microneedle and is not absorbed into the surrounding area. This is because the amount that flows out and is discarded increases, and if the inner diameter of the micro outlet is less than 1.0 mm, the injection liquid contained in the ampoule cartridge is not discharged smoothly through the micro outlet due to the surface tension.

In addition, the injection liquid contained in the ampoule cartridge is expensive, and discarding even a small amount immediately leads to economic loss. Therefore, there is a need for a technology that can efficiently use the injection liquid contained in the ampoule by slowly discharging it little by little.

In order to solve the above-mentioned problems, the purpose of the present invention is to provide an ampoule syringe that can be used efficiently by slowly discharging the injection liquid contained in the ampoule little by little.
