KR20010016400A - Injector having separable screw typed handle - Google Patents

Abstract

PURPOSE: An injector having a separable screw typed handle is provided to minimize the volume thereof, and to be used as a disposable injection as well as a general injection. CONSTITUTION: An injector consists of a cylinder(1) and a handle(2). A female screw part(2a) is formed on the inner circumference of the handle, and a male screw part is formed on the outer circumference of the cylinder. The cylinder and the handle are detachably coupled by the interaction of the female screw part and the male screw part. A needle(7) for gathering an injection liquid is contained in the cylinder. The cylinder also comprises a gasket(3). A lever gripping part fitted in a piston(4) is coupled with the gasket. The male screw part is also used to prevent the leakage of the injection liquid from the upper part of the cylinder. Therefore, the injector is capable to endure a pressure in the interior of the cylinder generated when the piston is moved up and down in the cylinder.

Description

Screw handle detachable syringe

The present invention is a prior art push-off separation drug syringe (Fig. 4) used in the pain-free self-injection type medicine syringe of Patent Application No. 99-5214 (Fig. 4) has a painless self-injection drug injection device Although it is easy to use, it is not suitable for use because it does not have a handle when used as a general syringe. In addition, when making a painless self-injectable drug injection device of the prior patent No. 99-5214 for a general syringe is large in length and diameter. In order to secure these disadvantages, the threads (1a, 2a) in the syringe (1) and the screw handle (2) was made to be used in the conventional self-injectable medicine injection device, and also can be used as a general manual syringe.

By separating the screw handle (2) and the push rod (4) has the advantage that the volume can be reduced to the maximum when portable and easy to operate.

The present invention can reduce the pain and anxiety when using a manual syringe by using a pain-free self-injectable drug injection device of the prior application patent No. 99-5214, by constantly injecting the injection rate into the skin It has the effect of suppressing the side effects caused by the syringe as much as possible.

The present invention is designed to improve the problem of the conventional syringe and the syringe for separating the medicine of the push rod (Fig. 4) to provide a syringe that allows anyone to inject the desired amount of medicine because the patient using the syringe is a self-injector. There is a purpose.

In addition, this syringe is limited to the drug injection device of the painless self-injection method in the prior application No. 99-5214, such as the pushpin separation drug syringe of (Fig. 4) Utility Model Registration No. 0194451, the space is used for the device In addition, it needs to be light and simple because it should be able to be used as a disposable syringe.

In order to achieve the purpose of this medicine injection syringe, the following measures were taken.

That is, in order to remove and attach the syringe 1 and the threaded handle 2 in the present invention, by making the screw portions 1a and 2a at the inner and outer diameters of each other, it is possible to remove and attach them.

In addition, the strength of the rod (4) to the upper and lower movement in the syringe (1) to make the threaded portion (1a) on the upper portion of the syringe (1) to withstand the pressure generated therein to prevent the injection solution leaks.

The internal principle works on the same principle as the syringe for syringe separation.

Figure 4 shows a conventional straw isolated medicine syringe.

As shown in the drawings, in the present invention, in order to remove and attach the syringe 1 and the threaded handle 2, the screw parts 1a and 2a are configured on the inner and outer diameters of each other, and the push rod of Utility Model Registration No. 0194451. In the same manner as the syringe for separating medicines, the medicine is embedded and the gasket (3) is inserted into the syringe (1) including the needle (7) for collecting the injection solution in the ampoule. 6) to form a structure to engage with the gasket (3).

The present invention relates to a disposable syringe for use in a medicine injection device of painless self-injection method of Patent Application No. 99-5214, and is formed in a minimum volume so as to be portable in the same way as a pushpin separating medicine syringe of Utility Model Registration No. 0194451 It is a screw handle-type syringe designed to be used as a general syringe.

Due to the present invention, the general person without medical knowledge can easily and conveniently carry out self-injection by detaching the medicine injection device of the painless self-injection method of Patent Application No. 99-5214, and can also be used as a general syringe. It has a wider range of application than a syringe with a syringe.

Claims (1)

Syringe (1) and the handle (2) in Figure 1a by dividing the medicine syringe (1a) and (2a) to make a screw portion to be removable.
