Definitions

  • the needle hub itself could be detachably connected to the syringe body. This would allow the user simply to unscrew one complete needle hub assembly and replace it with another.
  • the needle hub could be formed so as completely to contain the mechanism for restraining the needle against the bias of the spring or other propelling means.
  • the assembled needle hub and needles may be larger and thus easier for the user to deal with than simply just another gauge needle.
  • the needle hub can be formed with a ledge or the like to support a needle guard that will surround the needle before use and prevent sharps injuries, one can leave a guard on the needle hub while installing the entire assembly onto the rest of the syringe body.
  • Figure 11 is an isolated sectional view of a plunger in accordance with this invention.
  • Figure 57 is an elevational view of the syringe prior to needle retraction.
  • the enlarged area may be formed as part of the needle itself, or may be an additional piece fitted to the needle end.
  • the enlarged area may be formed of plastics, metal or other suitable materials.
  • Needle hub refers to a device that mates with the needle head.
  • the device may be a separate, generally elongated device placed in the needle assembly area between, e.g.. a base an one end of the needle assembly.
  • the needle hub may be formed as part of the base, needle assembly or other component located in that area.
  • a syringe may be provided for normal operation which permits changing a needle subsequent to use, but which, upon completion of normal operation and continued movement of a plunger, results in a triggering of a needle hub with the interchangeable needle to project such needle harmlessly into the plunger and body of the syringe.
  • Figure 1 is a cross-sectional view illustrating a subassembly of a needle hub 2, base 4, barrel 6, needle assembly 8 and an energy storage means 10 of a syringe 1 (shown in figure 13) of this invention in a normal pre- injection position.
  • energy storage means is a spring 10.
  • Base 4 is shown as a deformable body, but could be formed of multiple pieces, e.g. one piece that is deformable (such as an o-ring or the like) and others rigid.
  • Needle assembly 8 is affixed to the barrel 6 by guiding the threaded end of needle hub 2 through the center of passageway 1 and inserting needle assembly 8 into the front of barrel 6, until mating shelf 17 on needle assembly 8 contacts and is positioned against the top edge of the barrel 6.
  • Permanent joining between the needle assembly 8 and the barrel 6 can be accomplished by ultrasonic welding around the circumference of barrel 6 at overlap 7 between the two parts, or any other permanent attaching means can be used. Attachment of the needle assembly 8 to the barrel 6 creates a liquid tight seal between the two parts.
  • the end of the needle assembly 8 is positioned just in contact with engaging flanges 19 of supports 21, thus preventing movement of the base 4 and the needle hub 2 contained therein for normal syringe use.
  • the needle hub 2 is formed as part of a single molded syringe barrel 6, then the needle head 2 could be molded with a ridge or the like against which flanges 19 could bear.
  • a preferred material for the base 4 is an elastomer.
  • Supports 21 are illustrated in the preferred embodiment as a pair of opposing semicircular cantilevered beams, however, it is envisioned according to this invention that supports 21 could be connected and unitary, divided up further, or in some embodiments, be eliminated all together.
  • Figure 5 shows an isolated section view of the barrel 6.
  • Figure 5A is a cross-sectional view along line 5A-5A of figure 5 showing a finger support flange 40 of the barrel 6 of this invention.
  • an undercut 42 for locking the plunger into the barrel is shown at the finger support flange 40 of barrel 6.
  • a base shelf 3 and a base relief shelf 44 are illustrated. These internal offsets receive the base in the case of shelf 3, while the function of the shelf 44, is to provide room for base expansion as the base 4 is deformed and travels over hub 2 during operation.
  • Figure 6 shows an isolated view of the needle hub 2.
  • Top 46, flange 48, spring contactor 50, hub catch receiver 52 and hub block 54 are illustrated.
  • Needle hub 2 male threads 56 and bevel 22 are also illustrated and are used to releasably attach the needle head 12 to needle hub 2, while also creating a liquid tight seal between the two parts.
  • Figure 7 is an elevational view of the energy storage means 21 illustrated as a spring 10.
  • Figure 8 shows an assembly step accomplished by inserting the needle hub 2 into the base 4. Once inserted, a base wedge 58 is positioned for a substantially mating engagement over a flange 48 of the needle hub 2 which blocks needle hub 2 movement in both directions when inserted in the barrel 6. A liquid tight seal between the needle hub 2 and a needle hub seal 60 on the base 4 as shown in figure 8 is created at the needle hub 2. With the needle hub 2 blocked into the base 4, the next assembly step is accomplished.
  • FIG. 9 shows an isolated sectional view of the needle assembly 8 of this invention.
  • the passageway 15 is shown and is defined within the needle assembly 8.
  • a circular grove 64 on the needle assembly 8 serves as a guide for positioning the needle head 12.
  • the needle assembly 8 is transparent providing for viewing a joint between the needle hub 2 and the needle head 12 after the needle 14 is changed.
  • FIG 11 of the drawings is an isolated sectional view of a plunger 66 in accordance with this invention.
  • a capturing means 68 is illustrated for capturing the needle hub 2 with interchangeable needle 14 attached thereto into hollow 82 of plunger 66.
  • a plunger boot termination 70 is also illustrated and is designed to receive and mate with rupturable boot 72.
  • the plunger 66 has an enlarged thumb push 84 which, upon completion of a compression stroke, is substantially locked within recess 42 in the syringe body 6 by a mating head portion 94 of barrel 6 (shown in figure 24 A).
  • Figure 14 shows a side view of the needle guard 27, with a needle assembly closing member 90 tethered at the end thereof.
  • the closing member 90 is attached or tethered by a breakable tab 92 which can be of plastic construction and which is broken to remove the closing member 90.
  • Figure 14A is an enlarged view of the encircled area of figure 14 showing slot 25 and bead 57, used in conjunction with recess 29 (shown in figure 2A) for releasably fixing the needle head with its needle into the guard.
  • Figure 15 shows the needle guard 27 placed on the needle head 12, with the needle assembly closing member 90 tethered at the tip of needle guard 27.
  • the guard is placed into its position by snapping bead 57 shown in drawing 14A into recess 29 on fin 23 shown in drawing 2A.
  • Fins 23 on needle head 12 as seen in figure 2 mate with slots 25 in guard 27 as shown in figure 14 and releasably fix the guard 27 to the needle head 12 and prevent rotation of the needle head 12 in the needle guard 27.
  • the needle head 12 has been inserted into the open end of the passageway 15 of the needle assembly 8.
  • the needle hub 2 at its top 46, contacts a capturing means 68 which elastically flexes to permit the needle hub 2 to pass through the constriction formed by the capturing means 68 and the interwall of the barrel 6.
  • a capturing means 68 which elastically flexes to permit the needle hub 2 to pass through the constriction formed by the capturing means 68 and the interwall of the barrel 6.
  • FIG 23 where the needle hub 2 with replaceable needle 14 is shown having passed the capturing means 68 and captured within the hollow 82 of the plunger 66 where in the head of the needle hub 2 has moved back past the capturing means 68.
  • the plunger 66 has been substantially locked within recess 42 of the barrel 6, by a mating head portion 94 engaging a portion of the plunger 66 near a thumb push 84, as shown in figure 24A.
  • a liquid tight seal between a plunger seal 79 and a guard ring 86 is created.
  • the closing member 90 tethered to the end of the needle guard 27, can be inserted into opening 22 of the needle assembly 8, as shown in figures 23 and 24.
  • the closing member 90 is forced into position by pressing the front of the syringe against a heavy, solid object. Once the closing member 90 is lodged into position, the closing member 90 can be separated from the needle guard 27 with a twisting action, leaving syringe 1 as shown in figure 24.
  • This closure process can therefore be advantageously accomplished with a user ' s hands always remaining behind the opening left by the retracted replaceable needle. As a result of accomplishing the needle retraction cycle, syringe 1 is left as shown in figure 24.
  • Typical "filling" and “injection” cycles are depicted in regions I and II, respectively.
  • the base 4 balances the operating force and remains in its assembled position, as shown in figure 15. But, for positive forces applied to the syringe above threshold 39, the base 4 becomes unbalanced and begins to move in the direction of needle assembly 8.
  • the item numbers "83", “85”, and “87,” in region III of the graph respectively refer to where in a typical device the base 4 first begins to move, the needle hub 2 is released and the plunger 66 becomes substantially locked into the body 6.
  • FIG. 26 is an isolated sectional view of the needle assembly 109 of this invention showing locking slots 148 at the entrance of and recessed into the side wall of a passageway 123, which extend part way through the passageway 123.
  • Figure 26A is a cross sectional view of the needle assembly 109 along line 26A-26A of figure 26 showing a front view of the needle assembly 109.
  • Figure 27 of the drawings is an isolated view of the needle hub 1 13 showing locking bars 156 which extend radially out from the sidewall of the needle hub 1 13.
  • Figure 34A is a cross sectional view of the needle hub 213 along line 34A-34A showing a front view further illustrating locking bars 256.
  • Figure 35 is an isolated sectional view illustrating a base 211, wherein flexible supports have been eliminated and a taper 256 along the length of the base 211 is illustrated. Assembly of syringe 201 is accomplished in similar manner to syringe 1 and syringe 101.
  • the needle hub 213 is first inserted into and matingly held in the base 211.
  • the base 211 and the needle hub 213 are next inserted into the front of body 205, until the base 211 comes into contact with the barrel shelf 202.
  • the next step of the assembly process is accomplished by placing a boot 243 and a plunger seal 204 on the plunger 207, and inserting the plunger 207 into body 205 as illustrated in figure 39. It is common manufacturing practice to lubricate the interior wall of the body 205, usually with silicon, before insertion of plunger 207 into body 205. Assembly is completed by placing needle head 226 and needle 203 which is held in a needle guard 212 (in identical manner to syringe 1) into the open end of the needle assembly 209 and twisting needle head 226 onto the needle hub 213, which completes the assembly process. Rotation of the needle hub 213 is prevented by interlocking bars 256 and slots 248, as depicted in figures 33 and 34.
  • components of syringe 301 that are different from syringe 1 taught herein is a replaceable nose and needle cooperating with a body 305.
  • the needle assembly 309 is next rotated relative to the base 311 to match the base retainer slots 362 on the needle assembly 309 with retainer catches 364 on the base 311 (as shown in figures 47 and 47A).
  • the base 311 is forced into the needle assembly 309, partially compressing spring 321 and placing a shaft 316 of needle head 326 into passageway 323. Insertion of the subassembly into the needle assembly 309 is continued until base retainer catches 364 are latched into the base retainer slots 362, as illustrated in figure 47A. Once base retainer catches 364 are positioned into slots 362, position of base 311, and therefore needle head 326, is restrained in both directions.
  • the replaceable needle 303 can then be attached to, or removed from, the body 305 by inserting the base 311 end of the assembly into the open end of the body 305 and threading the assembly into position with the needle guard 312, until top 366 of body 305 (as shown in figure 45) mates with flat area 368 on the needle assembly 309 (shown in figure 40). In this position, a taper 314 on body 305 substantially mates with a taper 358 on the needle assembly 309 as shown in figure 48 to form a liquid tight seal between the two parts. To remove the needle assembly from the body 305, the process described above is reversed. Operation of syringe 301 is substantially the same as for syringe 1.
