Definitions

  • Such 4a syringe is particularly useful for emergency cases in the civilian or the military elds and may, for instance, constitute a part of an emergency box for factoriesmining works, autocars, sanitary stations etc. and may also be stored in hospitals for catastrophic incidents causing a greater number of victims.
  • the syringe may also be kept innational reserve such as for atomic bomb attacks or similar incidents.
  • the syringe and particularly a special embodiment thereof may with advantage be a part of the equipment ⁇ of the individual soldier in the military forces.
  • the syringe of the invention has a number of particularfeatures whichV should preferably .be employed in combination althoughneach of them isalseful separately without departure from the scope of the invention.
  • the syringe according to the invention consists of four main parts: a tubular body and, and housed therein, a longitudinally movable plunger, a separate collapsible receptacle of plastic material, and aninjection-needle provided with a holder to which it is secured.
  • the receptacle shall contain the liquid to beinjected and has a front.
  • the receptacle or the needle holder, with the needle fitted therein, or both must ⁇ be longitudinally movable in the tubular ⁇ body so as to bring :about a puncturing of said front end of the receptacle and establish communication between the interior of thereceptacle and the channel ofthe ⁇ injection needle when the injection isto be made.
  • the injection is carried out by the pressure exerted by the plunger whenr moved forwardly as by hand or by the force of a spring or the like.
  • Fig. l is a longitudinal section of an automatic syringe according to the invention in the loaded state as ready for use and Fig. ⁇ 2 is a similar section of the same syringe after use.
  • Figs. 3 and 4 are end views of the syringe as shown in Figs. 1 and 2, respectively.
  • Figs. 5 to 8 illustrate in the same way as Figs. l to 4 another type of an automatic syringe.
  • a syringe which'has to ⁇ be operated with two hands.
  • the syringe comprises attubular A.body 1 Vwhich consists of twohollow cylinders 51 and-52 secured to each other by a bayonet coupling 53 inalgnment so as to form a single tube.
  • AV sleeve -58 is secured to the wall 57 at the centre thereof to -form a guide for piece.
  • the wall and guide may be made as by -pressing in a Asingle
  • the wall material is so weak as to be easily punctured by the needle at the occasion of injection.
  • Vajshoulder 63 will be formed,V A helical .spring v67 is placed in its energetic compressedcondition about lthe stem 62 so as to be supported at its ⁇ front end by ajsupf porting surface on plunger ⁇ 19-and at its ⁇ rear end bywall 5a.
  • a washer 65 see also Fig. 4, having a central hole t @6fm the end of.
  • the .washer has two lugs 68 extending oppesitely .intov the hole 66 and -a superficial groove 69 extending ⁇ .along a .diameteng
  • Theportion ofthe stem ⁇ 62 extending through thewall-54 has ⁇ also two ⁇ lugs' 71 which project ,The pin has an 77.
  • The-lugs 68 andf71 are sopositioned .that in one relative position of the washer V.and thestern as. shown in Figs.
  • Ay receptacle 5 of, theAV accordion type is positioned in front of plunger 19. and-.a transversal rib 81 at vtherear end of the receptacle is engaged bythe slot 61 more or lesssnugly..
  • the front-portion 82 of the .receptacle tapers slightly forwardly and the frontend of portion'82l is closed by a wall 15 of aA thickness making it feasible to vpuncture it by the rear.; end of the needle as fwill be ex- 4.plained later. ⁇ .A needle yholder 11 is slidably tted in the ⁇ front portion-.52 in ⁇ rather close proximity tothe front end of ,receptacle 5.
  • the .holder 11 has aV .recess 12 shaped to engage the conical front end 82 of the receptacle and a cylindric recess 84.v at the front side in order-to take upthefsleeve Svfhen the holder is in its foremostposition.
  • pin 72 is first 'pulled out. This can take place automatically if, for instance, the
  • syringe is kept in a pocket and ribbon 74 is secured to the pocket or generally if the ribbon is fixed to some stationary member at the place where the syringe is kept.
  • the pin 72 will then be pulled out when the syringe is removed from the pocket or keeping place.
  • the syringe is then placed with its front end on the spot of the body where the injection is to be made and held firmly against the body with the one hand.
  • Washer 65 is then turned a quarter of a revolution whereby stem 62 and plunger 19 are released and pressed forwardly with great force by spring 77. Receptacle will thereby be moved forwardly until the front wall abuts the rear point of the needle 14.
  • the needle holder Upon further movement the needle holder will also be moved forwardly and the needle be brought into contact with spot 59 of the front wall 57. It is probable that at this moment the rear end of the needle 14 will have punctured wall 1S and liquid from receptacle 5 will have entered the channel of needle 14. The conical end 82 will engage the walls of recess 12 and the pressure within the receptacle will seal it against the needle holder. Upon still further movement needle 14 will puncture wall 57 and enter into the iiesh of the patient to be injected. All this will happen quickly and it is diicult to tell exactly when the puncturing of the walls occurs.
  • the front portion 52 is then separated from the rear portion 51 by opening the coupling 53 and push the receptacle 5 forwardly by pressing it with a linger or a pencil or a similar thing as a substitute for plunger 19.
  • the coupling should therefore be located at the rear side of the needle holder and near the receptacle.
  • FIGs. 5-8 illustrate a further embodiment of the present syringe, which can be manipulated with only ⁇ one hand.
  • the general structure of this syringe agrees with that illustrated in Figs. 1-4, the main difference being the mode of releasing the plunger. consists of a rear tube 51 and a front tube 52, in this case screwed to each other.
  • the rear tube 51 tapers rearwardly to form a cone S8 and is provided with an inner tube 89 extending forwardly from the rear end coaxially with tube 51 to form an annular space 91 between tube 89 and tube 51.
  • plunger 19 with the rearwardly extending stem 62, receptacle 5 and needle holder 11 carrying needle 14 are arranged as in Fig. l, spring 77 being housed in the annular space 91 and the tip of needle resting in sleeve 58.
  • a puncturable point in the front wall 57 as shown in Fig. l there is a hole in the wall right through in alignment with sleeve 58 in the present embodiment. This hole is sealed by a special cover 97 on the outer surface of the wall.
  • Stem 62 is locked in the position illustrated by a special locking arrangement comprising a sleeve 93 slidably mounted on tube 51 and having at its rearmost end somewhat liexible tongues 94 extending inwardly so as to rest i on the edge of the conical end S8 of tube 51.
  • the stem 62 protrudes rearwardly from said conical end 88 and has just outside the edge of end 8S a circumferential groove 95, into which the tongues 94 penetrate.
  • the tip 96 of the stem 62 will thus serve as a shoulder resting upon the inner ends of the tongues 94.
  • a safety pin 72 is passed through a hole in the stem 62 just outside the groove 95 but it is in the first hand the tongues 94 that hold the stem in the loaded position illustrated.
  • the pin 72 has an eye 73 to which ribbon 74 is secured. This ribbon may be attached to the inside of a pocket or any other place where the syringe is kept for emergency cases.
  • tubular body .4 now strikes the syringe with the front wall 57 against thc spot of the body where injection shall be made.
  • the sleeve 93 will continue a short distance sliding on tube 51.
  • the tongues 94 will be pulled out from their engagement with the tip 96 of the stem which latter is thus released so that spring 77 can force plunger 19 forwardly' so as to carry out the injection procedure as described above.
  • Fig. 6 illustrates the syringe after use and shows clearly receptacle 5 in its collapsed state.
  • the front portion 52 can be unscrewed from the rear portion 51 and the injection be carried out by pressing the receptacle 5 as described above.
  • the seam between the portions 51 and 52 shall be near the place where receptacle 5 is housed.
  • all parts but for the needle 14 can be 'and are preferably made of artilicia-l resin.
  • the syringe can thus be made from relatively cheap material and can be thrown away after use. It is also an advantage that such material allows for a neat appearance and that the syringe can be made transparent.
  • the needle can consist of two separate parts one of which is litted in the needle holder projecting rearwardly therefrom.
  • the frontal needle part, the actual injection needle, may then be secured to the syringe in front of the needle holder and means for communication between the needles be arranged between the two needle parts.
  • a hypodermic syringe comprising a tubular body, a rst end wall at least partially closing the rear end of said tubular body, a second end wall closing the other end of said tubular body and having at least a central portion which is perforatable by a hypodermic needle, a needle holder slidably mounted within the end of said tubular body adjacent said second end wall, an injection needle carried by said needle holder, said needle extending both forwardly and rearwardly from said holder and having puncturing points on both ends; extensible spring means positioned within said tubular body in the end thereof adjacent said first end wall, means for locking said spring means in compressed position, a compressible ampoule adapted to contain injectable liquid positioned within said tubular body between said spring means and said needle holder, and means for releasing said locking means, whereby said spring means applies pressure to said ampoule which in turn applies pressure to said needle holder resulting in the perforation of said second end wall by one end of said needle, the perforation of said ampoul
  • a hypodermic syringe as defined in claim l in which the front end of said ampoule is frusto conical and the rear surface of said needle holder contains a frusto conical recess adapted to receive the frusto conical from end of said ampoule.
  • a hypodermic syringe as defined in claim l in which said means for locking said spring means comprises ampoule, said ampoule having a transverse rib on the rearv end thereof and said plunge".- having a transverse slot in the front surface thereof adapted to receive said rib.
