4 Claims.
'Ihis invention relates to a syringe, and particularly to one of the so-called disposable cartridge type.
Various substances must be injected into a human or animal body intramuscularly; the approved technique for effecting such an intramuscular injection is to force the sterile syringe hollow needle into the body at a desired location and, when the needle has attained the approximate depth desired, to apply a reduced pressure to the needle in an attempt to draw blood through the needle and into the syringe barrel; if it is possible to aspirate blood, then the needle must be relocated, the presence of blood being an indication that the needle is in communication with a blood vessel and is not within a muscle.
Various substances, of which penicillin is one example, are of such a viscous nature that they cannot be placed readily in the ordinary syringe; in addition, after use, the syringe must be cleaned with special solvents while if any moisture is present, a gum is formed; further, the ordinary syringe cannot be sterilized readily and is not suited to emergency or home use. For these and other reasons, many substances, such as penicillin, are most advantageously dispensed in a cartridge in conjunction with a syringe structure, the cartridge and frequently the syringe being thrown away after use.
In the disposable cartridge syringes heretofore provided, the problem of aspirating has provided considerable difliculty and various involved techniques and relatively cumbersome devices` have been employed. For example, one common form of device includes a removable rubber cap placed over the open end of the syringe barrel; when the needle is supposedly positioned intramuscularly, the rubber cap is worked in an attempt to provide an aspirating pressure upon the needle. The cap is of relatively small extent and the aspirating pressure applied is frequently not sufficient to give a true indication of the location of the needle end. Also, after the aspiration procedure has been followed, it is necessary to remove the rubber cap from the end of the syringe barrel, sterilize the cartridge, insert the cartridge in the syringe barrel, place the cap on the end of the cartridge, then effect the injection. Between the aspiration operation and the actual injection, the syringe barrel and needle can move because of the several manipulations which must be made while the attempt to insert the sterilized cartridge frequently results in what amounts to a (Cl. 12S-220) relocation of the needle. rI'his procedure is typical ci" the diiculties inherent in the use of various of the prior art syringes.
In accordance with the present invention, we provide a relatively simple and rugged disposable cartridge syringe which, because of its low cost and simplicity of operation, can be manu-- factured at a relatively low cost and so can be thrown away after use. Briey, the syringe of the present invention includes the combination of a hollow needle, a syringe barreland a cartridge which, after removal of the usual sheath which protects the sterile needle, co-acts with the cartridge barrel as a piston to provide an aspira-ting pressure to determine iithe blood can be drawn. Thus, the cartridge is inserted in the barrel by the manufacturer, and the entire syringe unit can be provided by the manuu facturer as a sterile unit so that once it has been determined that the end of the hollow needle is in an intramuscular position, it is only necessary to move the cartridge to engage that endA while its hollow needle is supposedly in an intrav muscular position.
It is in general the broad object of the present invention to provide a novel syringe of the cartridge type and which can be manufactured so inexpensively that, if desired, the syringe can be thrown away after use.
A further object of the present invention is to provide a novel syringe oi" the cartridge type which is particularly adapted to the intramuscular injection of such materials as penicillin and the like.
The invention includes other objects and features of advantage, some or which, together with the foregoing, will appear hereinafter wherein the present preferred form oi syringe embodying the present invention is disclosed. f
In the drawings accompanying and forming a part hereof, Figure l is a side elevation, partly in section, showingrthe device assembled butprior to use, while Figure 2 is a generally similar view, but showing the device in use. Figure 3 is a side elevation, partly in section,
through a modified form of the device.
Figure 4 is a side elevation, partly in section,
transversely upon the upper end of the barrel 6. The lower end of the barrel is closed as at 3, and includes a projection upon which is seated a sheath IG. The end 3 of the barrel 6 is fitted with an annular extension II, the end of the sheath fitting between the extension 9 and the annular extension II in a sealing relationship. It is to be noted that extension S and extension II terminate'in a common plane, the advantage of this being presently explained.
A hollow needle I2 extends through projection 9 and end 8 into the interior of the barrel ,6, the needle being protected prior to use by sheath It.
A cartridge of the material to be dispensed is generally indicated by numeral2I and comprises a container in the form of a bottle having a reduced neck portion 22 and anend closure made up of a rubber or other elastic insert 23, held in place by a metal rim 24; the rubber insert has an arcuate face 26 sloping to the central axis of the bottle so the bottle can be drained completely.
The diameter of the container is such that it approximates closely that of the interior ofthe barrel 6 while the neck portion 22 is reduced. In accordance with this invention, a ring 2l of a sealing material is provided about the lower end of the cartridge 2i and between the bottle and the barrel 6 so that an eiective seal is provided between the barrel and the bottle.
'In use, the unit is supplied by the manufacturer in that form in which it appears in Figure l, the sheath being in place, the needle, the interior of the barrel, and the end of the cartridge being sterile. When it is desired to inject the material in the cartridge, the sheath I is removed `and the needle I2 is forced into the desired location in a patient, usually until the iiat and coplanar ends of extension 9 and ring II are against the patients skin. The coplanar ter mination of extension @and ring il is advantageous for it ensures that extension 9 will not beforced into the iiesh and the needle i2 inserted too deeply. Also, it enables the operator to gauge the depth of insertion of the needle by feel, as well as by sight. Further, it provides lateral support for the syringe so that it will remain erect and will not fall over, thus enabling an operator to release the syringe temporarily, if this is necessary, without danger of the needle being placed under a side strain with possible injury and pain to the patient.
To eiect the injection, the upper end of cartridge ZI is rst moved rearwardly to apply an aspirating pressure to the interior of the needle to ascertain whether or not blood can be drawn. If blood can be drawn, then it is necessary to relocate the needle. If blood cannot be drawn, then the needle is in position for the patient to receive. the injection, whereupon the end of cartridge v2i moved toward the patient, the projecting transverse ears i being grasped as between the middle and the foreinger and the end of the cartridge being forced inwardly by the thumb, until the upper end oi' the needle is forced through the closure 23 within the cartridge ZI. rl'fhe substance in the cartridgeis packed'and sealed therein originally under a pressure in excess of atmospheric so that ywhen the closure 23 is pierced by the hollow needle the content of the cartridge is forcefully projected through the hollow needle and into the patient by the pressure in the cartridge. The rubber closure seals itself about the needle.
The Vcartridge can be 4supplied in'place as in Figure 1, in which instance a unit ready for instant use is available. If desired, however, barrel 6 can be sterilized and closed with a cap which is only removed when the unit is to be used; in this case, the end of the cartridge 2I is sterilized before being inserted in the sterile barrel. The t between the cartridge 2| and the barrel need only be sufficiently tight to apply the desired aspirating pressure; if aspiration is not necessary, then the seal between the container and the barrel need only be such as will maintain the sterility of the common areas of the container and the barrel; such a seal can be provided by cotton, felt, wax and the like to admit only bacteria-free air to the sterile space between the barrel and the container.
If desired, the sealing means between the barrel and cartridge can be carried by the barrel, as isl shown in Figure 3 wherein the upper end of the barrel (3 is provided Iwith a recess 3I in which a sealing ring 32a. is carried to provide either a gas-tight or a bacteria-tight seal be-A tween the cartridge ZI and the barrel proper.
The structure shown in Figure 3 is further modied in that the cartridge 2i is of tubular forni closed by end closures 38 and 39 and inciudes a separator 32 therein dividing the container into'a rst region 3B in which the material to be injected is carried, and a. second region S5 which is lled with a gas under pressure suf-V cient to force the separator 32 to move toward the opposite end of the cartridge :EI upon piercing of the frangible end closure 38. This structure permits the syringe to be used to effect an injection even when the hollow needle I2 is projecting upwardly or horizontally.
In the modification shown in Figure 4, a flexible sealing means such as a cap 4I, made of rubber or other elastic material, is provided between and about the barrel, being secured to the barrel by a sealing ring 2. In use, the exible cap maintains the desired sterile condition and permits the cartridge 2l to be suitably manipulated to apply an aspirating pressure so that .a gas-tight fit between the cartridge and the barrel is not necessary.
From the foregoing, we believe it will be appar# ent that we have provided a novel and simple form of cartridge, and of a syringe which can be manufactured so inexpensively that either or both can be disposed of when desired and which enables an injection to be made very simply and with a materially simplified technique.
We claim:
