Disclaimer (all) which will not appear on the advertisement page: Amendments 12/26/2018 -------------------------------------------------- -------------------------------------------------- ------ 02/03/2018 ------ (OCR) Page 1 of the number 2 pages Clause 1. Apparatus (1) Provides therapeutic fluid containing the cylinder (2) made with Molded plastic material And the elastic seal (6) by being used with the debt end (3) of the cylinder body (2) and the seal sue to prevent fluid leakage. This tip can be punctured with a needle or a cantaloupe. The said chel (6) is made of a thermoplastic elastomer material that is molded in The spatula is placed inside the tip (3) of the cylinder (2), where the holder (8) is placed on the outside of the tip (3). It is characterized by that the elastic seal (6) is positioned across the tip (3) of the barrel body (2), and that the tip (3) of the barrel body (2) is part. The axial protrusion (5) continues extending through the seal (6) that is formed in the mold over the spatula 2. Equipment (1) as specified in Clause 1. It is characterized by the fact that the tip (3) of the cylinder body (2) is flared along the radial width. And a molded seal body The top of the spoon (6) will come in and fixed along the inner ring and on the outside of the tip. (3) 3. Equipment (1), as specified in Clause 1 or 2, is unique in that the vertical protrusion of the said debt. At least that SUK (5) will be used as a code viewer. 4.

The inside of the said tube (3) and it has an amorphous end surface (12). 5. Method for manufacturing the device (1) Provides a therapeutic fluid composed of the cylinder (2) made of material. Molded plastic And an elastic seal (6) used at the tip (3) of the cylinder body (2) that can be punctured with a needle. At the intervals for the said seal (6), a thermoplastic material is used. Plastic that is an elastic material to make it. And the said seal (6) will be molded in a over-mold. The spoon is placed inside the tip (3) of the barrel (2) in order to form a part of the holder (8) on the outside of the tip (3). Only that the tip (3) of the cylinder body (2) is formed so that the axial protrusion (5) continues, and that page 2 of the number 2 such seal ( 6) This, after it is formed in its overlapping mold on the tip (3) of the cylinder body (2), it is interrupted by the vertical protrusion of said (5) 6. The method described in claim 5 at the helm is characterized by that the tip (3) of the barrel (2) shall be formed so that the morphology is flared along the radial width. And the said cheel (6) will be molded in the overlapping mold In order to allow it to adhere along the circle The inner and outer rings of the flared end. (3) 7. The method specified in Clause 5 or Clause 6, which is unique to \ 'that Shield that goes up The figure in the said overlap mold (6) is formed in such a way that the internal axial portion (11) extends into the said cylinder body (3) and has a sheave end ( 12) Convex morphology ------------ 1. a therapeutic fluid that consists of a cylinder (2) made of plastic material made Figure in mold And an elastic seal (6) applied to one end (3) of the cylinder body (2) in a sealed way to prevent fluid leakage. This tip can be punctured with a needle or cannula. Where the device sounds Said to have a unique feature that The seals (6) are made of a thermoplastic elastomer material that Be formed in a mold, overlapping the body inside the end (3) of the cylinder (2), where there will be One is a placeholder (8) located on the outside of the end (3). 2. The equipment specified in claim 1, where it is characterized by that such tip (3) of the barrel (2) is flared out to a circular width. And a molded seal body These overlays (6) are firmly welded onto the inner circle and on the outside of the ends. That bloomed out as mentioned 3) 3.Equipment set forth in any of the above claims, where there is a characteristic that such ends (3) of the barrel body (2) have axial protrusions. (5) that protrudes through the body Seals formed in such overlapping dies (6). 4. Equipment as stated in Clause 3, which has the characteristics that Protruding part Part of the axis At least (5) will be used as a unique identifier of the code. Such a device used to deliver therapeutic fluids 5.Equipment, as set out in any of the above claims, where there is a characteristic that the seals formed in such overlapping dies (6) will have an internal axial component (11). Protrude into The barrel (3) and it has a convex end surface (12). 6. A method for the manufacture of a therapeutic fluid consisting of a cylinder (2) made of molded plastic material. And an elastic seal (6) applied at one end (3) of the cylinder body (2) that can be punctured with a needle. Where the method has the characteristics that As for the seals (6), a thermoplastic elastomer material is used to create it. And the aforementioned seal (6) is molded into a mold, overlapping the end (3) of the cylinder (2) in order to be assembled. Up as part of the retainer (8) on the outside of the end (3). 7.
