CATHETERIZATIQN COMPACT Edna Porter, Los Angeles, Calif.
Application December 10, 19.421, Scriai No. 458,481
This invention relates to a container for sterilizing articles and for protecting them against desterilization.
Although the container provided by this invention may be used to protect a great many different substances and articles against contamination by germs, it is more particularl the object of the invention to afford this protection to the instruments and substances used in catheterizations of patients.
It is usually necessary, under present conditions, for the doctors attendant to spend about half an hour for the purpose of sterilizing and assemblying for use the various articles and instruments to be used in performing a catheterization. This task includes using several sterilometers in order to determine that the sponges, gloves, forceps, catheters and other accessories have been sterilized. By the use of the present invention these articles are all sterilized en masse, only one sterilometer being used and much time being saved and trouble avoided.
Objects of the invention in addition to those above indicated are: To provide guarded access to certain compartments Of a container of a plurality of sterilized articles so that other articles within the container than those to which access is had will not be contaminated; to provide improved means for admitting sterilizing steam to the interior of the container without later impairing the sterile condition of the contents thereof; to provide improved means for supporting within the container a. sterilometer in a position for convenient inspection without opening the container; and to provide for the container an improved combined lid and trapdoor structure.
Other objects, advantages and features of invention will hereinafter appear.
Referring to the accompanying drawing, which illustrates what is at present deemed to be a pr ferred embodiment of the invention,
Fig. 1 is a perspective view of the complete article, the lid being partly open to disclose interior parts. This View illustrates the interior compartments, such compartments being empty and the sterilometer being carried interiorly by the lid. The open position of the trapdoor carried by the main lid is indicated by dotted lines.
Fig. 2 is a fragmentary plan view of the device looking down upon the trapdoor, a portion of the window being broken away in order more clearly to disclose the sterilometer.
Figs. 3 and 4 are enlarged sectional detail views taken respectively on. lines 3-3 and 4-4 of Fig. 2.
Referring in detail to the drawingthe embodiment of the invention shown therein comprises an elongated box arrangement consisting of side walls 3 and 4, end walls 5 and 6, a bottom wall 1 and a lid 8 secured to said side wall 4 by a plurality of hinges 9.
Within said box arrangement is a plurality of longitudinally extending partitions I53, I I and i2, and a plurality of transverse partitions E3, H5, H5 and it. By these partitions there is provided a compartment I l which extends from end to end of that side of the structure to which the lid is hinged, said compartment being adapted to contain catheters; a compartment E8 to contain forceps; a compartment 19 to contain glOVes, towels, syringes and miscellaneousequipment; a compartment 20 to contain sponges; a compartment 2| to contain waste and provided with a group of apertures 22; and a compartment 23 to contain samples of urine, the latter compartment having the part of its back wall which is formed by the partition It furnished with a vertical row of graduations 23m to indicate the quantity of the sample taken. The apertures 22 are only for the purpose of letting the steam out during sterilization. They are placed in said compartment 22 for the reason that this compartment always remains empt unless it is filled with the waste matter afterperforming a catheterization.
In addition to the aforesaid compartments there are provided, in the front part of the midlength portion of the container, two juxtaposed compartments 24 and 25, the front compartment 24 bein utilized as a storage place for a sterile solution and the compartment 25 therebehind being utilized as a container for oil, these two containers being used only after the compact containing the equipment for performing a catheterization has been brought from the autoclave in which the assembly has been sterilized, or from other places where kept in readiness for use, access being provided to the compartments 24 and 25 without opening the main lid 8, which might contaminate the sterilized articles, this being avoided by opening only the trapdoor 26 in a door opening 8m contained in thelid 8.
Describing the trapdoor 25 in, detail, said trapdoor is hinged to the main lid 8 by a hinge 23a, a rat-trap spring 2%, coiled around the hinge pin 260, being utilized to maintain the trapdoor in a yieldably closed condition. Said trapdoor is provided with Wings 21 which, in the closed condition of the trapdoor, extend alongside the transverse walls It and M in an outside relation to the intervening compartments 24 and 25. Said trapdoor is desirably operated by means of a knob 28, the opening of the trapdoor being yieldingly opposed by said spring 2612, and when said trapdoor is opened to an extent sufficient to provide access to compartments 24 and 25 said wings 2'! aid in shielding the contents of compartments 20 and 23 against splashing when the oil and sterile solution are added to said compartments 24 and 25 preparatory to performing a catheterization.
The lid 8 has through it an opening 83: (see Fig. 4) wide enough to admit the winged sides of the trapdoor, said opening extending out to the flange 8 of the lid. In order to prevent the front edges of the trapdoor wings 2'! from striking against the front edge of the opening 80: through the lid 8, said wings are arcuately beveled at 211).
All the transverse and longitudinal partitions which have been mentioned have their upper edges located in a slightly downwardly spaced relation to the top edges of the side and end walls 3, 4, and 6. This arrangement provides for a circulation of the steam throughout the several compartments of the device and not only insures sterilizing said compartments but also of the equipment placed within them, when the compact is placed in a sterilization chamber.
Owing to the downwardly spaced relation existing between the closed lid 8 and the partitions within the box provision is made for preventing the trapdoor 26 from inclining downwardly when both the lid and trapdoor are in the closed condition. For this purpose the small horizontal rest plate 29 shown in Fig. 4 is attached to the upper edge of the front wall 3 of the box to arrest the closing movement of the trapdoor before it moves to an inclined position.
The contents of the compact are always wrapped in suitable gauze, paper or towels prior to being placed within the container.
Due to the fact that the trapdoor 25 provides only guarded access to the sterile solution compartments there is never any danger that access to said compartments contaminate the sterilized equipment in the other compartments.
When the trapdoor 26 is opened by means of the knob 28, this trapdoor is utilized as a pull wherewith to open the main lid 8, without providing an additional handle therefor.
The elongated sterilometer 39, which may be of a conventional character, is shown supported from the underside of the lid 8 by means of a pair of spring clips 3! each of which has one end portion secured to the lid and has a detached end portion directed toward the free edge of said lid. Adjacent to one end portion of the mounted sterilometer the lid 8 has a window 32 covered with a pane 33 of any suitable transparent material, and through this window the sterilometer is observable to determine whether or not the contents of the container have been properly sterilized. If the sterilometer displays white it indicates an improper sterilization.
What is claimed is:
1. A container of the kind described comprising a lid, a box to which said lid is hinged, said box having within it partitions thereby dividing off a plurality of compartments underlying said lid when it is in the closed position, said compartments having open tops when said lid is in the open position, a door in said lid capable of being opened and closed independently of the latter and when open affording access while said lid is closed to certain of said compartments independently of the others, and means carried internally by said door to guard against desterilization of adjacent compartments when said door is opened to afford access to others of said compartments.
