Specication of Letters Patent.
Patented Feb. 1, 1921.
Application illed April 9, 1917. Serial No. 160,823.
State of Minnesota, have invented certainy new and useful Improvements in Syringes; and I do declare the following to be a full, clear, and exact description of the invention,
such as will enable others skilled in the art to which it appertans to make and use the same. l
My invention relates to syringes and more partlcularly to hypodermic syringes and the object is to provide a syringe of this character which is simple in construction, cheap to manufacture and easy to operate and which will. produce the maximum of eiliciency in its operation. t
Another object of my invention is to provide a' syringe of this character which is constructed in a novel manner in which the inlet of the interior of the syringe is constructed through the handle and the plunger of the syringe, thereby providing a compact neat device which may be readily and easily applied and operated. ,y
o this end my invention resides in the novel' construction, combination and arrangement of parts to be more fully described and claimed taken in connection with the accompanying drawing which forms a part of this application and 1n whichz.
Figure 1 is a side elevation of my 1mproved syringe with the contalner connected thereto;
Fig. 2 is a longitudinal central sectlonal view through the same. i
Brieiiy described, my invention comprises a syringe havinga barrel .provided at one end with a discharge nozzle, said barrel having a plunger or piston operable therein and rovided with a piston rod or stern extending beyond the opposite end of the barrel and havin on its outer end a transverse handle. Xtending through the handle at the outer end of the stem and through the stem and plunger is an inlet passage having communication with the interior of the syringe and a valve is located in the lun er head for controlling the passage. 4uita le finger grips-are formed on the body of the syrlnge and form component parts of the handle for the entire syringe.
Referring more particularly to the drawthe syringe comprises a barrel 1 which is cylindrlcal in shape and is made of any suitable material, said barrel having detachably secured thereon at its front end a cap 2 provided with an enlarged portion 3 containing a valve chamber 4 and having a threaded extension 5 projecting therefrom over which is secured a needle 6. A4 suitable check valve 7 is disposed in the chamber 4 to control the discharge end of the barrel. This entire construction comprising the cap 2 and the discharge needle 6 may be embodied as a unit if desired and may be otherwise varied in its formation, it being understood that I do not limit myself specifically to this manner of constructing the same as this is merely 'a preferred embodiment of my invention which I refer to hereinafter as a discharge nozzle.
The rear end of the barrel is closed by a capmember 8 removably threaded thereover and providedvwith lateral diametrically opposed curved finger grips 9 for a purpose to be hereinafter described. The cap member 8 is pro'vided at its center with a suitable packing guide member 10 to surround an aperture through the center of the cap formed to receive therethrough the piston rod or stem 11i-of a lunger or piston 12 adapted to be operate within the barrel 1. At its rear end thestem is provided with a laterally extending forwardly bowed handle 13 which extends substantially the same distance as the linger grips 9 on the cap 8 so that the handle 13 may be grasped by the hand of an operator with the fingers of the hand engaged over the curved grips 9 on the barrel to draw the handle member 13 inwardly toward the rbarrel and force the stem carrying the lunger inwardly in the barrel to discharge uid contained thereinthroughthe discharge nozzle at the opposite end.
The head 12 of the plunger is provided lwith a centrally enlarged portion containing a valve chamber 14 which is in communication with the interior of the barrel and also in ,communication with an inlet passage 15 extending lon itudinally through the stem 11 and lateral y of the handle 13 at the end of the stem. The
handle 13 is provided at the end having communication with the passage 15 with a rearwardly curved nipple 16 over which a suitable tube may be secured to supply 'tluld to through one-half sov the interior of the syringe. This nipple also insures proper engagement of the handle 12 With the users hand. Disposed within the valve Chamber 14 in the central portion of the head 12 of the plunger is a suitable check valve"l 17 of similar conformation to the check valve disposed in the discharge nozzle. However, ll desire it to be understood that I do not specifically limit myself to any one form of valve as it is obvious that the shape of the chamber as well as the valve may be altered Without in any way intertering with or changing the principle of operation of the syringe.
The head 12 is provided with an annular iange 18 which is adapted to act as a socket to receive therein a portion of a retractile coiled spring 19 disposed between the plun ger head and between the cap 8 on the plunger barrel and suitably secured at its ends to the cap and to the head respectively to normally retain the plunger head in retracted position adjacent the end of the barrel.
lVhen it is desired to operate the syringe. the handle 13 is forced forwardly and the head is thus forced forwardly in the barrel against the action of the spring 19 so that when pressure upon the handles is released, the spring will act to draw the plunger back .into retracted position-` whereupon the valve 17 in the head of the plunger will be actuated to open the inlet passage for communication with the interior of the syringe to .refill the same. In the preferred form of the device l have found it desirable to employ a reservoir 20 for the fluid which it is desired to supply to the interior of the syringe, made in the form of an ordinary test tube and having connection with the handle 13 in the syringe by means of a short flexible tube 21 so that when the syringe is in use the test tube may be hung suspended over the wrist of the operator.
Vhile l have shown and described certain specific forms of the construction and details of the construction and operation of my syringe, l -desire it to be understood that I do not wish to be specifically limited to these but any such may be used as will fall Within the scope of the appended claims,
l claim:
l. A syringe comprising a barrel having at its front end' an outlet provided with a forwardly opening check valve having in its rear end an opening, a piston in said barrel, a tubular piston rod extending rearwardly from said piston through said opening, a forwardly opening check valve in said piston controlling communication between the interior of said tubular rod and the barrel in advance of said piston, a pair of lateral finger grips on opposite sides of said barrel at its rear end, a transverse forwardly bowed thrust handle joined at its center to the rear end or said rod and having a tubular half whose interior communicates with the interior of the rod, the free end ot' said tubular halt of the handle heilig curved rearwardly to insure proper engagement ol said handle with the users hand and forming a nipple for the attachment of a tube 1 or supplyingvthe barrel with the Huid to be iised.
l. A syringe comprising a barrel having at its front end an outlet provided with a forwardly opening cheek valve and having in its rear end an opening, a piston in said barrel. a tubular piston rod extending rearwardly from said piston through said Opeling, a forwardly opening check valve in said piston controlling communication between the interior of said tubular rod and the barrel in advance of said piston, a pair ot lateral linger grips on opposite sides of said barrel at its rear end, a transverse thrust `aandle joined at its center to the rear end of said rod and having a tubular half whose interior communicates with the interior of the rod` the free end of said tubular half or' the handle being curved rearwardly to insure proper engagement of said handle with the users hand and forming a nipple for the attachment of a tube for supplying :he barrel with the fluid to be used.
