permit it to be discharged for use with ao hypodermic syringe.

A still further object is to provide a case that will effectively protect the instrument while the sterilizing liquid reservoir is being refilled.

The principal feature of the invention consists in the novel construction of the case, whereby the slidably tubular instrument holder is extended into a fluid well to ster ilize the instrument and upon removal of the instrument eflects the sealing of the well.

In the drawings, Figure 1 is an elevational view of my improved case.

Figure 2 is a longitudinal sectional View showing a hypodermic syringe therein.

Figure 3 is a longitudinal sectional view of the case showing the cover removed therefrom and the fluid well sealed.

Figure 1 is an enlarged detail perspective View of the inner sliding tube and spring removed from the casing, saidinner tube having the Valve end removed.

A pocket sterilizing'case fort-he use of physicians and for the use of persons requiring frequenthypodermic applications is very important in that it enables the use of instruments without danger of infection.

In the construction herein shown the case is formed of a barrel portion 1 which is open at both ends and formed with the inner bore slightly reduced toform a shoulder 2 and a counterbore 3' is formed-at the outer end of the reduced bore forminga valve 'seat.

The ends of the barrel 1" are slightly re,- duced and provided with external threads 4 and 5. r V

A closed casing 6 is threaded on to the threaded portion t and forms a closed well 7 r V end of the syringe engaging the bevelled seat at the reduced end of the barrel.

A cap 7 is provided to thread onto the threaded portion of the barrel -tov close the 1 pocket.

casing 6. I

the wall of the tube 9 above the valve flange a seat against which the bevelled portion 16 of the hypodermic syringe 17 engages.

upper'end, said cap being provided with a suitable clip 8 to hold it securely in the Within the barrel 1 is arranged atube 9 r 1 preferably formed of a non-corrosive metal, said tube being slidable in the reduced portion 10 of thebarrel. 1 I

The outer end is formed with an outward flange 11 slidably engaging the inner bore of the barrel. r i a l A coil compression spring 12 encircling the tube-9 and enclosed between said tube and the barrel engages the flange 11 atone end and the shoulder 2 at the other end.

. The tube 9 is provided with a laterally extending flange'13 at its inner end whichis adaptedto engage the'seat formed by the counterbore '3 and seals the fluid containing The flange is preferably formed by a threaded cap 14 which is threaded in through the inner end of the tube 9.

A plurality of holes 15 are cut through 11 so that when the tube is depressed into the fluid casing 6, the sterilizing fluid will enter the end of the tube and when the casing moves outwardly tothe position shown in Figure 2, the fluid will drain out from the tube, leaving a small quantity in the cap end when the fluid casing 6 has been sealed.

The flanged outer end of the tube is champered on its inner periphery and forms The needle 18 0f the syringe extends close to the bottom of the tube 9 but cannot touch 7 the tube and when the said tube 9 is de- M pressed into the well formed-by the casingg 6 and the cap 14 is secured on the outer end ofthe barrel 1, the sterilizing fluid completely surrounds the needle. V i I In the use of this device the well casing 6 y may beiremoved at any time for replenishing the sterilizingfluid therein and thesyring'e needle is protected bythe tube 9. The tapered at the outerend of the tube prevents the escape of the sterilizing liquid from the tube 9 if the case is inverted or laid in a horizontal position.

lVhen the cap is removed the spring 12 forces the tube 9 outwardly and the syringe with it until the valve end closes into the counterbore sealing the casing 6.

The liquid drains out with the exception of a small quantity retained in the cap end and this is used in cleansing the slain before the inserting of the needle in the slain.

When the syringe has been removed from the case the closure of the casing 6 by the valve prevents the escape and loss of the sterilizing fluid.

A device such as described isextremely useful. Its construction is rugged and will withstand considerable abuse without dam age.

It has been shown particularly applied to the use ofa hypodermic syringe but it may be used with equal facility and benefit with other small clinical instruments.

What I claim as my invention is 1. A sterlllzlng case, comprising a cylin- :drical barrel threaded at the ends. a well end of the barrel in double sealingcontact to close the passage between the barrel and well casing, said flanged end acting as a stop to limit the outward. movement of the tube. said tube being open at the other end and having perforations adjacent to its flanged end, a cap threaded on the other end of the barrel and spring means for operating said tube to seal said well casing.

2. A sterilizing case, comprising a cylinder open at the ends and having the bore thereof reduced at one end and an annular valve seat surrounding the outer end of said reduced bore, a tube slidably arranged in the reduced bore and having an annular flanged head forming a. valve to engage said cylinder seat and a flanged inner end engaging the larger bore, a spiral compression spring encircling said tube within the larger bore and engaging the flange ef said tube to hold the valve'end thereof against said seat. said valve and seat forming a stop to limit the movement of said tube. perforations in the slidable tube adjacent to the valve end, a casing enclosing the valve end of the cylinder and forming a well to contain a sterilizing fluid, and a cap closing the .other end.

3. A sterilizing casing, comprising a cylinder having well at one end adapted to contain a sterilizing fluid and a reduced bore intermediate of its length. a tube slidable in said reduced bore having a valve at its inner end and holes through the side wall adjacent to said valve to permit the fluid to enter the tube on depression. the other end of said tube being flanged outwardly and formed with a tapered seat, a spring encircling said valve and holding the valve end closed, an instrument adapted on insertion into said cylinder to engage said tapered seat at the outer end of said tube and depress the latter and having a tapered portion to fit the seat of said tube to form therewith a liquid seal to prevent the outward escape of said fluid from said tube into the barrel interior when said tube is depressed, and a cap threaded on the end of said cylinder to engage the instrument and depress the slidable tube against the spring pressure to extend the perforated end into the well.

i. In a sterilizing holder for instruments, combinationof a casing adapted to house the instrument to be sterilized and having a separate sterilzing fluid compartment at the lower ens, and a tube resiliently supported in said casing having a seat adapted to form a seal against said instrument to prevent the passage of fluid from the tube into the easing and having its lower end perforated. and adapted to extend into the fluid in said compa rtment.

In a sterilizing holder for instruments, the combination of a casing adapted to house the instrument to be sterilized and having a separate sterilizing fluid compartment at the lower end, a tube resiliently supported in said casing having a seat adapted to form a against said instrument to prevent the 'iassage of fluid from the tube into the casing and having its lower end perforated and dapted to extend into the fluid in said compartment, and valve means carried by said tube forming a seal between said fluid compartment and the interior of said tube when the instrument is removed from its sealing engagement with said tube.
