- the holster includes tab means at its forward end to detachably lock it to the pumping station and to actuate a ram to drive the plug or piston in the rearward end of the vial into the vial's reservoir to force the liquid through the flexible microbore conduit to the needle under a wide range of pressures.
- the flexible conduit is coupled to both the holster and the needle handle in a high pressure seal.
- the open or forward end of the holster 11 includes a pair of radially extending locking tabs 20 and 21 (best seen in FIG. 3B and 4B) while the base or closed end is formed with a central, external hub 22 adapted to receive the flexible conduit 13 in sealing relationship.
- the base end is also formed internally with a hollow, molded, piercing probe 22 A having a tip sharpened in at least three planes to define a piercing tip capable of penetration of the rubber seal 11 c of the vial when it is inserted into the holster.

Abstract
Description
- The invention is a flexible conduit and carrier assembly for conveying liquid such as local anesthetic under elevated pressure from a vial to a hollow needle adapted to be implanted in the tissue, particularly the gingival tissue of the mouth.
- The applicant's U.S. Pat. Nos. 4,747,824 and 5,180,371 disclose apparatus and method by means of which local anesthetic can be administered virtually without pain into the tissues, particular the mouth. In accordance with this invention, a vial of anesthetic is mounted in a holster unit detachably mounted at a programmed and controllable pumping station which forces the anesthetic from the vial at predetermined flow rates with greater precision than can be achieved with conventional hand syringes. The holster includes means to pierce the rubber diaphragm of the vial and to convey the liquid through a flexible microbore tube to a handle assembly carrying a conventional hollow needle to inject the anesthetic into the tissue.
- Such holster, flexible conduit and needle assemblies must be disposable for sanitary reasons and must, therefore be relatively inexpensive. On the other hand, they must be engineered so they can quickly and easily be mated with anesthetic vials and then attached to the pumping station and just as easily be disassembled and not infrequently re-loaded for use on the same patient. They must also be light in weight, able to withstand high liquid pressures and readily manipulated at difficult injection sites.
- The object of the invention, therefore, is to provide an assembly which meets all of these difficult and somewhat incompatible design criteria.
- In accordance with the invention, a holster design is provided which, as a single die cast unit, is capable of receiving a sealed vial of anesthetic and of automatically puncturing the membrane seal at the head end of the vial by means of an integral, sharppointed, hollow probe at the base of the holster to tap into the reservoir of liquid anesthetic. The holster includes tab means at its forward end to detachably lock it to the pumping station and to actuate a ram to drive the plug or piston in the rearward end of the vial into the vial's reservoir to force the liquid through the flexible microbore conduit to the needle under a wide range of pressures. The flexible conduit is coupled to both the holster and the needle handle in a high pressure seal.
- Because it is frequently required that a second vial of anesthetic be used for the same patient, it should be possible to quickly detach the disposable assembly from the pump, eject the spent vial and insert a fresh vial. In accordance with the invention, swift removal of the spent vial is facilitated by arranging the geometry of the holster so that the vial can be gripped to detach it from the holster, when it is to be discarded. This can be achieved, for example, by means of a pair of complementary diametrically opposed finger apertures in the side wall of the holster to enable the vial to be tightly gripped and pulled out of the holster against the friction of the probe gripped by the rubber membrane of the vial.
- FIG. 1 is a plan view of a holster, flexible conduit and needle assembly embodying the present invention, and also showing, disassembled, an anesthetic vial and a portion of a pumping station;
- FIG. 2 is a view in longitudinal vertical section of the needle end of the handle portion;
- FIG. 3A is a view in vertical longitudinal section of the holster portion of FIG. 1;
- FIG. 3B is a view in horizontal longitudinal section of the holster portion of FIG. 1; and
- FIGS. 4A and 4B are two views in cross section showing the front end of the holster inserted in the pumping station, the latter showing the holster rotated 90° to engage the locking tabs and to start the microprocessor.
- Referring to FIG. 1, the invention is shown as embodied in a
disposable assembly 10 having an open-endedtubular holster 11 for receiving a vial orcartridge 11 a, of anesthetic and for attachment to a programmedpumping station 12. Theassembly 10 includes a flexible, microbore tube orconduit 13 coupled to ahandle assembly 14 having a rigidelongated carrier 15, the free end of which is joined to ahollow needle 16 connected to theconduit 13 in fluid-tight relationship, as best seen in FIG. 2. - The
flexible conduit 13 is threaded through acentral bore 17 in thecarrier 15 to receive the base end of thehollow needle 16. The needle is carried by acap 18 having aneedle sealing hub 19 and fitted over the free end of thecarrier 15, also in sealing relationship. The pencil-like geometry of the handle assembly enables it to be held between the forefinger and the thumb of the doctor to enable the careful implantation of the needle in the most difficult injection sites. - The
holster 11 as best seen in FIGS. 1, 3A and 3B is preferably cast in plastic as a unitary structure having a hollow cylindrical body to receive at its free or open end thecharged anesthetic vial 11 a, head orfront end 11 b first. The head end of a conventional anesthetic vial includes apenetrable rubber seal 11 c held by a metal sealing ring while the back end is sealed by a plug orpiston 11 d which is slidable into theanesthetic reservoir 11 e of the vial to drive the liquid forward. - The open or forward end of the
holster 11 includes a pair of radially extendinglocking tabs 20 and 21 (best seen in FIG. 3B and 4B) while the base or closed end is formed with a central,external hub 22 adapted to receive theflexible conduit 13 in sealing relationship. The base end is also formed internally with a hollow, molded, piercing probe 22A having a tip sharpened in at least three planes to define a piercing tip capable of penetration of therubber seal 11 c of the vial when it is inserted into the holster. Thus the flexible,microbore conduit 13 is connected to theanesthetic reservoir 11 e. - With the
vial 11 a fully seated in theholster 11 with theprobe 22a penetrating therubber seal 11 c, theassembly 10 is ready to be releasably locked to the pre-programmedpumping station 12. To this end, the wall of the pumping station is formed with acircular aperture 12a with diametrically opposedradial extensions radial tabs wall 12. At the same time thelocking tab 20 rotates into engagement with aprogramming switch 22 connected to amicroprocessor 23 in thepumping station 12 to actuate aplunger 24 to drive the plunger into thepiston 11 d in thevial 11 a. The plunger is then controlled by the doctor and the micro-processor to complete the injection in accordance with the teaching of the applicant's aforesaid patents. - When the injection is completed (or the vial exhausted), the holster is then detached from the pumping station by reversing the insertion procedure. Removal of the vial from the holster requires that the
rubber seal 11 c, which is in tight frictional engagement with thepiercing probe 22a, be readily detached from the probe. This is accomplished in accordance with the invention by forming in the holster diametrically opposedfinger apertures pumping station 12. - While the invention has been described above in reference to a preferred embodiment thereof, it will be understood that it can take other forms and arrangements. The invention should not, therefore, be regarded as limited except as set forward with the following claims.
