Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to an intralipidic drug injector.

Injecting drugs directly into the bulge is effective for treating bulge diseases such as various bulge inflammations and candidiasis, but a specialized syringe for use in these treatments has not yet been developed. The current situation is that this is not the case.

The present invention has been made to provide an intralipidal drug injector that can be safely and smoothly inserted into the fistula, and that can easily apply the drug evenly around the entire circumference of the barrier. An outer cylinder has a closed hemispherical shape, has a closed end, and has a large number of drug outflow holes drilled in the side wall so that the closed area increases sequentially from the distal end toward the distal end, and the terminal barrier is provided in the outer cylinder. an inner cylinder that can be inserted and removed from the outer cylinder to push out the fluid medicine filled in the outer cylinder from each of the outflow holes;
Moreover, the cross-sectional shape of the outer cylinder side wall portion is shaped like a gourd.

Hereinafter, practical examples of the present invention will be described with reference to the drawings. 1st
As shown in Figures 3 to 3, the syringe of the present invention has an outer cylinder 1 made of synthetic resin, and an inner cylinder that is removably inserted into the outer cylinder 1. (Piston) Consists of 2.

In detail, the outer cylinder 1 has a hemispherical shape with a closed tip,
In addition, the distal end is closed, and a large number of drug outflow holes 3 are formed in the side wall from the distal end to the distal end over a required range (approximately 30 to 40 skins) so that the entrance area becomes larger at every several stages. It has been drilled. Further, the cross-sectional shape of the side wall portion of the outer cylinder 1 is shaped like a gourd, which is close to a circle. Furthermore, an insertion stopper 4 within a ridge is provided protruding from a desired position on the side wall of the outer cylinder 1. The inner cylinder 2 is inserted into the outer cylinder 1 and extrudes the fluid medicine filled in the outer cylinder 1 from each of the outflow holes 3, so that its tip corresponds to the shape of the tip of the outer cylinder 1. It has a hemispherical shape.

Finger hooks 5 and 6, which are larger than the stopper 4, are provided at the ends of the outer cylinder 1 and the inner cylinder 2, so that the fingers can be caught when extruding the drug from the respective outflow holes 3.

Further, at the end edge of the outer cylinder 1, a claw part 7 is provided at one end to be hooked to the finger hook 6 of the inner cylinder 2 in order to prevent the medicine filled in the outer cylinder 1 from being pushed out from the outflow hole 3 except when in use. ' is connected to the other end of the sub-child stopper 7. This connecting portion is integrally formed so that the two are connected in a thin state during molding. The syringe of the present invention "normally, each outflow hole 3
Fill the required amount of the required drug into the outer tube shell, which is covered with a cap (not shown) or a synthetic resin film, etc., insert the inner tube 2 into the outer tube 1, and place it on the finger hook 6 of the inner tube 2. Since the claw part of the locking tool 7 is kept in a phosphorized state, the insertion position of the inner cylinder 2 into the outer cylinder can be maintained at a constant position except when in use to prevent the medicine from flowing out from each outflow hole 3. It can be prevented.

When using this syringe, first remove the caps etc. covering each outflow hole 3, and insert the required length into the patient's foot from the tip of the outer cylinder 1.

At this time, the tip of the outer cylinder base is hemispherical, so it can be inserted smoothly without worrying about damaging the twill wall, and there is a stopper 4 on the side wall of the outer cylinder base, so it cannot be inserted more than necessary. There is no need to press (lift) or put your face on the uterus.Thereafter, as shown by the imaginary line in FIG. Rotate or remove the entire stopper (of course, you can do this before inserting it), then hook your fingers on the finger hooks 5 and 6 and push the inner tube 2 into the outer tube 1. As a result, the medicine in the outer cylinder 1 is pushed out from each outflow hole 3 and sprayed onto the ridge wall.

At this time, a large number of drug outflow holes 3 are provided in the side wall of the outer cylinder 1, and none are provided in the tip of the outer cylinder 1, so the drug flows through each outlet due to the pushing pressure of the inner cylinder 2. The drug is extruded from the hole 3 and poured over the entire periphery of the bulge and even onto the shark hairs on the inner wall of the bulge, thereby making it possible to sufficiently spread the therapeutic effect, and also to prevent the drug from being injected into the uterus. Also, the outflow hole 3 is connected to the outer cylinder 1.
Since the open area gradually increases from the distal end to the distal end, approximately the same amount of the drug is extruded from each outflow hole 3 over time, and is evenly applied to the entire circumference of the rod wall. Further, since a stopper 4 is provided on the side wall of the outer cylinder 1, it is possible to prevent the medicine from flowing out from the base inlet. After use, the outer cylinder 1 and the inner cylinder 2 can be removed as they are.

By the way, the shape of the bulge cavity is in the shape of a so-called H-shape, with the front and rear surfaces being flattened in the middle, and slightly bulging on both the left and right sides.

In the present invention, ``As shown in Figure 3, the side wall of the outer tube bulge is shaped like a nearly circular gourd, so when this syringe is inserted into the bulge, the side wall of the outer tube bulge is shaped like the lumbar cavity. Correspondingly, a state of engagement is obtained, and the application of the drug to the ridge is evenly performed, and an excellent therapeutic effect can be expected.The present invention is not limited to the above-mentioned examples. It goes without saying that, for example, the shape and mounting position of the locking tool 7 can be changed as desired, and various other changes can be made without departing from the gist of the present invention.

As mentioned above, according to the present invention, t {i) A large number of drug outflow holes are formed in the side wall of the outer cylinder so that the closed area increases sequentially from the distal end toward the distal end. Approximately the same amount of the drug is extruded over time, allowing the drug to be applied to the entire circumference of the mucosa and even to the hair on the inner wall, allowing the therapeutic effect to be fully distributed.

{ii) Since no drug outflow hole is provided at the tip of the outer cylinder, injection of the drug into the uterus can be prevented.

{iii) Since the tip of the outer tube is semispherical, it can be inserted smoothly into the fat, and it is safe without worrying about compressing or damaging the uterus.

■ Since the cross-sectional shape of the side wall of the outer cylinder 1 is formed into a lion shape, when this syringe is inserted into the bulge, the side wall of the outer cylinder 1 corresponds to the shape of the knee cavity and can be engaged. This allows the drug to be applied evenly and evenly around the entire barrier, and excellent therapeutic effects can be expected.

Demonstrates excellent effects such as
