Definitions

  • the objective of designing the all-in-one injectable tube is to decrease the multiple steps involved in fluid collection, preparation, and administration within the scientific research and healthcare settings. Users can store, add or remove fluids directly from tube (for injections) - without having to transfer fluids or fractionated products to a new equipment for further procedures. The risk of cross-contamination and microbial contamination is higher in a multi-step procedure. Thus, the all-in-one injectable tube will help improve the user’s time and minimize the risk of contamination and infection.
  • the all-in-one injectable tube is a double screw cap tube that offers two openings.
  • the top of the tube (larger diameter) has an outer ridge for a screw cap and inner ridge for a triple-lock stopper.
  • This stopper features a thread that meshes with the inner ridge of the tube for a secure seal.
  • the triple-lock stopper contains a hole, located at its top part. With this unique design, the user can directly connect another syringe to this triple-lock stopper to add additional fluid from the syringe into the tube or remove fractionated fluid layers from tube into another syringe.
  • the triple-lock stopper can be connected to a plunger.
  • the design of the middle region of the all-in-one injectable tube is a hollow cylinder with no ridges. Thus, when connected to a plunger, the triple-lock stopper moves freely.
  • the bottom of the tube (smaller diameter) has an opening for either a screw cap or a needle hub.
  • the advantage of all-in-one injectable tube is the double ridges at the outer and inner rim of the top of the tube.
  • the outer ridge allows user to tightly secure and lock the tube prior to centrifugation and fractionation and the inner ridge meshes the triple-lock stopper.
  • the unique designs of the triple-lock stopper are the following: (1) the triple-lock stopper is tightly locked in place in the tube, which creates a vacuum within the tube. This environment improves the process of adding fluids into the tube without having to use excess pressure. Thus, the tube can be centrifuged effectively without leakage. (2)
  • the top of the triple-lock stopper can be connected to a syringe with luer lock tip.
  • the two screw caps offer secure tight seals and access for injections, blood drawn, and fluid collection.
  • the attached plunger can smoothly move the triple-lock stopper along the tube barrel - close to the fluid level. Once the needle is disconnected and the double screw caps are sealed, tube becomes a container.
  • the all-in-one injectable tube offers a closed sterile system for collecting and transferring fluids, reduces plastic and glassware usage, and improve user’s time.
  • Figure 1 represents the components of the all-in-one injectable tube design when attached to a typical plunger.
  • Figure 2 represents the components of the all-in-one injectable tube design when attached to a luer lock tip syringe.
  • Figure 1 and 2 display the two functions of the all-In-One Injection tube, when attached to a typical plunger or a luer lock tip syringe, respectively.
  • the all-in-one injectable tube is a double screw cap tube, which offers two openings (1).
  • the top of the tube (larger diameter) has outer ridge (2) for a screw cap (3) and inner ridge for a triple-lock stopper (4).
  • This triple-lock stopper (6) features a thread (5) that meshes with the inner ridge of the tube for the secure seal.
  • the triple-lock stopper contains a hole with smooth surface, which is approximately 4/5 deep of the stopper’s length (7).
  • the hole on the triple -lock stopper is designed to contain a hollow plastic cylinder (8).
  • the top half has a smooth surface and the bottom half has a helical ridge surface (9). Due to its unique design, the triple-lock stopper can be connected to a typical plunger or a syringe.
  • the plunger (10) has a stopper (14) attached to its tip.
  • the plunger is inserted to the syringe barrel (11) from the top.
  • the other end of the barrel is a hollow tip (15), attachable to a needle.
  • the external syringe tip is twisted onto the hollow cylinder’s ridges in the middle (9) and at the rim (13).
  • the all-in-one injectable tube has two functions. First, the tube can be attached to a typical plunger. After the plunger is connected to the triple-lock stopper, the user can begin to collect fluid into the tube. When the fluid collection is completed, the user moves the plunger away from the tube until the triple-lock stopper is aligned with the inner ridge of the tube. Now, the triple -lock stopper is screwed in place. Then, the plunger is removed from the triple -lock stopper by rotating in a clockwise manner. Finally, a screw cap is used to tightly secure the fluids inside the tube. For the process of blood fractionation, the tube can be centrifuged and the fractionated layer(s) of interest can be used for administration.
  • the tube can be attached to an external syringe.
  • This function allows users to add fluids from the syringe directly into the injectable tube.
  • the syringe tip is inserted into the triple-lock stopper by rotating in a clockwise manner. Once the syringe tip is locked tightly with the triple-lock stopper, the plunger of the external syringe can be pushed along its barrel to expel liquid into the injectable tube.
  • the external syringe can act as a sliding plunger for the injectable tube. Therefore, this design offers a closed system drug transfer.

Abstract

La présente invention concerne un tube injectable tout-en-un qui est un tube à capuchon à double vis, qui offre deux ouvertures. La partie supérieure du tube comporte une cannelure externe destinée à un capuchon à vis et une cannelure interne destinée à un bouchon à triple verrouillage. Ce bouchon comprend un filetage qui vient en prise avec la cannelure interne du tube pour une étanchéité sûre. De plus, le bouchon à triple verrouillage présente un trou, situé au niveau de la zone centrale supérieure. Le trou sur le bouchon à triple verrouillage est conçu pour s'adapter à un cylindre creux en plastique. Pour la zone intérieure du cylindre creux, la moitié supérieure présente une surface lisse et la moitié inférieure présente une surface à cannelure hélicoïdale. Grâce à la conception unique de la surface à cannelure hélicoïdale, le bouchon à triple verrouillage peut être relié à un piston typique ou à une seringue.
