Claims.
This invention relates to syringes of the type used for making injections into patients, and in particular a syringe in which sterilization of the syringe is not required.
The purpose of this invention is to provide an improved method for inserting a needle in a syringe casing in which the needle is inserted with a lateral instead of a longitudinal movement so that it does not come in contact with the parts of a syringe casing or hands of an operator.
In the conventional type of syringe where the needle is inserted in the end by hand it is necessary to sterilize both the needle and holder each time the syringe is used. An object of this invention is to make use of a syringe that need not be sterilized prior to its use, when the cartridge method is used. The present syringes on the market must be sterilized, both the needle and the syringe, before use; the disposable syringes now marketed and needles are already sterile, and are discarded after use. With this thought in mind this invention contemplates a syringe where it is not necessary that the syringe be sterile, and where the syringe may be used repeatedly Without sterilization as a sterile needle is placed in the syringe without sterilization and without being made unsterile, because the needle is extended through and carried by a wedgeshaped holder and the syringe casing is provided with a slot in one side through which the needle is inserted with a lateral movement and also a wedge-shaped slot which is positioned to receive the holder in which the needle is carried.
The object of this invention is, therefore, to provide means for installing and retaining a needle in a syringe casing whereby sterilization of the syringe is not necessary, with each use.
Another object of the invention is to provide a syringe casing having a slot in one side to provide means for inserting a needle with a lateral movement and also having means for inserting a cartridge and ejecting fluid therefrom whereby an end of the cartridge is punctured by the needle.
A further object of the invention is to provide an improved method of mounting an injecting needle in a syringe in which sterilization of the syringe is not required and wherein a syringe of a simple and economical construction is provided.
With these and other objects and advantages in view the invention embodies a syringe having a cylindrical casing with a slot extended through one side and the adjoining portion of the base and a wedge-shaped holder whereby a needle carried by the holder may be positioned in the end of the casing with the holder secured in a slot of the casing and whereby the needle is positioned to puncture the end of a cartridge, the opposite end of which is positioned to be engaged by a plunger extended inwardly through the opposite" end of the casing.
Other features and advantages of the inven- 2 tion will appear from the following description taken in connection with the drawing wherein:
Figure 1 is a side elevational view illustrating the improved syringe with the needle extended therefrom and with the plunger in the extended position.
Figure 2 is a vertical section on an enlarged scale through the casing of the syringe taken on line 2-2 of Figure 1.
Figure 3 is a cross section taken on line 33 of Figure 2 showing the needle holder in a slot in,
the end of the casing.
Figure 4 is a detail showing a section through: the lower end of the casing taken at a right angle: to that shown in Figure 2 and taken on line 4-4 of Figure 5.
Figure 5 is a cross section through the lower' end of the casing taken on line 5-5 of Figure 2..
Figure 6 is a perspective view showing the lower end of the casing of the syringe.
Figure 7 is a similar view showing the wedgeshaped needle holder with a needle held therein..
Referring now to the drawings wherein like reference characters denote corresponding parts the improved syringe of this invention includes a tubular casing [0, a needle holder II, a plunger l2, a bushing 13, and a closure cap 14, the plunger, bushing and closure cap being of conventional design.
The needle holder H is wedge-shaped in two directions having inclined upper and lower surfaces l5 and IS with similarly shaped edges IT and I8 and a base IS on the end of the casing 10 is provided with a similarly shaped slot 20 providing a socket whereby in positioning a needle 21 in the syringe the tapering end of the holder is inserted in the slot 20 and the needle is secured in operative position as illustrated in Figure 2.
The outer end of the holder 1 l is provided with an extension, also Wedge-shaped in both vertical and horizontal planes and this extension, which is indicated by the numeral 22 provides means for gripping the holder by hand and also provides a handle to facilitate holding the device with forceps and other tools. The holder H is also provided with an opening 23 through which the needle 2| extends and with the needle positioned in the holder it is readily installed in the syringe by placing the holder in a slot 24 in the base 19 with the upper end or point of the needle passing through a slot 25 in the side wall of the casing.
At the time the needle is inserted the cartridge, as indicated by the numeral 26, is not in position in the casing, so that the slot in the lower end of the casing is open and the needle may be inserted or removed with a lateral movement instead of'the conventional longitudinal movement. The needle may, therefore, be inserted in the syringe Without being engaged by the fingers of a nurse or other attendant and without coming in contact with nuts, bushings or other parts ofasyringe.
With the needle in position, as illustrated in
