Abstract

A holder for a hypodermic syringe particularly for veterinary use has an elongate tubular housing 10 with a tube 22 screwed to one end, the tube 22 forming a cavity for receiving a hypodermic syringe 28 with its needle extending towards the free end of the tube. A sleeve 24 is resiliently mounted at the free end of the tube 22 and covers the needle at all positions of the plunger 32. When the sleeve 24 is pushed against the animal patient, the sleeve retracts and the end of the needle passes through the end of the sleeve and punctures the patient's skin. A push rod 12 axially slidable within the housing 10 can then be operated by a pressable head 18 so that the plunger 32 of the syringe 28 is moved forward and the animal is injected. <IMAGE>

Description

SPECIFICATION Holders for hypodermic syringes The present invention relates to holders for hypodermic syringes, particularly syringes for use for veterinary purposes.
It is very often extremely dangerous for a veterinary surgeon to inject an animal, whether to cure it of a disease, innoculate it, orto effect euthenasia on the animal. It is an object of the present invention to overcome this difficulty.
There is now proposed, according to the present invention, to provide a holderfora hypodermic syringe comprising an elongate tubular housing, a cavity within said housing, adjacent one end thereof, adapted to receive a hypodermic syringe, with its needle extending towards said one end, a sleeve resiliently axially movable relative to the syringe, when so held, effective to coverthe needle of the syringe, when the plunger of the syringe is in any of its positions, in the forward position of the sleeve relative to the syringe, and means operable from the opposite end of the housing and adapted to move the plunger of the syringe axially, so that when the sleeve is pushed against the patient, the end of the needle passes through the end of the sleeve and, when said means is operated, the liquid in the syringe is discharged to inject the patient.With such a construction, it is possible for the veterinary surgeon to remain at a significant distance from the animal. For example, the elongate housing can be made of the order of 1 metre or more in length.
Because of the resiliently axially movable sleeve, the needle is always covered until the sleeve is deliberately retracted by pushing against the animal.
The means for operating the syringe could comprise an abutment within the housing, which is engaged by the plunger of the syringe, whereby further forward movement of the holder will cause the abutment to press the plunger forward. However, in a preferred construction, a push rod is provided which is operable from the other end of the holder.
Once it has been decided to inject the animal, a safety cap, which can be provided at the end of the sleeve, is removed, and the sleeve is then pressed against the animal's flesh, so that the sleeve retracts and the needle passes through the open end of the sleeve. The push rod is then operated to injectthe animal. The surgeon is thus always maintained at a safe distance from the animal and is unlikely to suffer any damage to his person.
The sleeve itself can be movable, or possibly the syringe can be movable relative to the sleeve, which itself could be fixed to the housing. However, this would involve the use of a further relatively movable part.
The sleeve is preferably retractable under the action of a spring which is advantageously arranged within the sleeve so that it can be maintained clean.
In order to provide the cavity and to assist in inserting the syringe a tube may be secured, for example by screwthreading, onto the one end of the housing, and this tube itself forms the cavity and has the sleeve axially reciprocable relative thereto.
Advantageously, the push rod is provided with a reduced cross-section shaft which passes through the other end of the housing through a resilient grommet therein, the grommet and shaft being an interference fit, so that the shaft can only be moved by applying a considerable force. The force is adjusted to give the desired ease of operation without accidentally operating the push rod. The shaft is preferably graduated, to indicate an amount dis pensed by the syringe when the shaft is moved a certain distance.
In orderthatthe present invention may more readily be understood, the following description is given, merely by way of example, reference being made to the accompanying drawing, in which the sole Figure is a schematic cross-section through one embodiment of holder according to the present invention, with a hypodermic syringe therein.
Referring now to the drawing, the holder illustrated therein comprises an elongate tubular housing 10 preferably of the order of a metre or slightly more in length. Axially reciprocable, in a telescopic manner, within the housing 10 is a push rod 12 which has a reduced cross-section shaft 14, extending through the end wall 15 of the housing. Formed on the shaft 14 are axially spaced graduations 16 and a manually pressable head 18 is provided at the free end of the shaft. In order to provide a bearing for the shaft, and to restrain the movement slightly of the push rod, a resilient grommet 20 is provided in the end wall 15 and is an interference fit on the shaft 14.
Atube 22 can be removably threaded onto the free end of the housing 10 by means of a screwthread 21.
A sleeve 24 is axially reciprocable relative to the tube 22 and axial movement is limited to a certain amount by an abutment 23 on the sleeve 24. At its lefthand end the sleeve 24 is provided with central aperture 25.
Located within the sleeve 24 is a coil compression spring 26.
When the tube 22 is removed, it forms a cavity of a size to accommodate a hypodermic syringe 28 having a barrel 30 and a plunger 32, with the end of the plunger, when the tube is screwed back on the holder 10, abutting the end of the push rod 12.
It will be seen that the needle 34 of the hypodermic syringe 28 is wholly within the sleeve 24 in the advanced position of the latter, even when the plunger 32 is in the advanced position illustrated in the drawing.
A safety cap 36 can be provided to fit over the aperture in the free end of the sleeve 24.
The backward position of the plunger 32 is illustrated in chain dotted lines in the drawing. The actual position of the syringe is determined by the cap 37 of the syringe being engaged by a positioning ring 38 in the tube 22 and by the end of the screwthreaded housing 10.
The rear end, that is the righthand end, of the sleeve 24 is provided with axially extending slots, which do not appear in the drawing, which enable the sleeve to be forced in through the forward end of the tube 22 whereupon the abutment 23 springs out behind an internal shoulder 40 on the lefthand end of the tube 22, to retain the sleeve in position.
In use, the hypodermic syringe is filled, to the desired amount, and fitted into the cavity formed in the tube 22, which is then threaded onto the free end of the housing 10.
One approaches the animal, and removes the cap 36. The sleeve 24 is then pressed against the animal so that the spring 26 is compressed, and the tip of the needle appears through the aperture 25 to puncture the animal's skin. The head 18 is then pushed inwardly either fully, or by the desired number of graduations 16, so that the plunger 32 is pushed forward and the animal is injected with the desired amount of liquid.
It will be appreciated that because the sleeve covers the needle at all times, except when the holder is pushed against the animal, there is little danger of any harm coming to the veterinary surgeon, particularly when the cap 36 is put in place.
Further safety measures could be provided so that the push rod cannot be operated except in certain circumstances, for example, by twisting the shaft prior to pushing the head.
It will be appreciated that the interior of the sleeve 24, particularly when the cap is in position, as well as the needle of the syringe, can be maintained sterile at all times until the cap 36 is removed. Thus one can carry around the charged syringe in its holder without any danger either to people using the assembly, orsubsequentlyto an animal being injected.
