Claims priority, application Switzerland May 6, 19:8
7 Claims. (Cl. 134-452) My invention has for its object an improvement in apparatus disclosed in British Patent No. 752,326 for the cleaning of syringes.
According to the specification of said patent, the injection syringes to be cleaned are disassembled and the syringe components are subjected inside a centrifugal washing machine both to centrifugal action and to the action of at least one radially directed water jet. To this end, there are used tubular carriers open at their opposite ends and inside each of which the components of a syringe are introduced, except the actual injection needle.
The above-mentioned specification disclosed also a particular auxiliary arrangement which serves for the cleaning of the injection needles. This auxiliary arrangement included long necked funnels inside which the needles are positioned, said funnels being subsequently inserted inside the openings of the cylindrical perforated wall of the washing machine drum.
Now, practice has shown that injection needles can be cleaned satisfactorily in this manner although the auxiliary arrangement provided to this end is inconvenient in so far that each funnel is suitable for the reception of only one needle at a time, whereas obviously a larger capacity is desirable.
My present invention has for its object the provision of an arrangement to be fitted inside the perforated drum of a centrifugal washing machine which arrangement is far superior and more efiicient than the funnel shaped needle-carriers conventionally resorted to.
According to the invention, the arrangement includes a plurality of flat needle carrying-containers each of which is inserted and secured in radial vertical locations inside the washing machine drum designed especially for this purpose, while said container is open along its narrow side directed inwardly when in its operative position and is provided on its opposite narrow side with removable needle holding means. The latter may be fitted inside the container to further the loading thereof in a manner such that the superposed needles assume a floating location in the corresponding sections of the needle-container.
The advantage of such a needle-container lies in the fact that it may be provided with a larger number of needles. The drum may obviously be designed without any further difficulty in a manner such that it may carry a large number of such containers. It is particularly important that such containers may be filled with water during operation of the centrifugal washing machine so that the bores in the nipple connections of the needles are subjected to the pressure of a water column subjected in its turn to centrifugal action, whereby the water is urged under a high pressure through the hollow needle shank and provides a thorough cleaning action.
The accompanying drawings illustrate by way of example an embodiment of the invention.
'FIG. 1 shows a centrifugal washing machine for the cleaning of the injection needles partially in elevation and partly in section.
' for three successive containers 6.
FIG. 2 shows on a larger scale a group of three needlecontainers adapted to receive the needles to be cleaned, said containers being arranged radially inside the drum of the washing machine, the central container being drawn completely in horizontal cross-sectional view while the two others are only drawn partly in horizontal crosssectional view.
FIG. 3 shows a single container in front view.
FIG. 4 shows separate an auxiliary component for said container.
FIG. 5 is a cross-section of a modification of the container.
FIG. 6 is a perspective view of the lower section of a component of the last-mentioned container.
PEG. 7 shows said last component in front view.
The centrifugal washing machine includes inside a stationary casing It, a drum 2 adapted to revolve round a vertical axis and provided with a cylindrical wall perforated as shown at 2a. into said machine, there opens a pipe 3 through which a washing liquid such as water carrying a cleaning medium is urged under pressure so as to enter the machine. Said pipe 3 ends with the section 3a extending along the vertical axis of the drum 2, and the wall of which is provided with longitudinal nozzleforrning slots 3b.
There is arranged concentrically with the drum axis a ring of bars or rods 4 forming a sort of cage, as shown also in FiG. 2, said rods being connected at their lower ends with the drum bottom 2b and at their upper ends with a ring 5 having an angular cross-section.
In the annular space formed between the rod cage and the cylindrical drum wall, are arranged flat containers 6 extending in radial vertical planes, as illustrated in FIG. 2 Said containers 6 are open at their inwardly directed narrow sides when inserted inside the drum. The upper and lower walls of each container are provided at their inner ends with an arcuate recess 6a. The front or outer transverse wall of each container 6 is provided with a longitudinal slot 612 as illustrated in FIG. 3, each slot terminating at its upper end with a transverse horizontal broader section 6c. This broader section may be closed by means of a slider 89 guided over a slot 7 formed in the upper wall of the container. Said slider includes an upper rectangular plate 8 and a lower plate 9, folded at right angles, said plates 8 and 9 being interconnected by means of a stirrup-shaped member 10, the legs of which extend through the slot 7. The slider may thus be shifted in both directions along said slot 7. In its closed position, the bent section of the lower plate 9 engages the inside of the outer terminal wall of the container 6 and closes the rectangular slot section 60 in said outer wall as illustrated for the container drawn in the lower section of FIG. 2.
FIG. 4 illustrates a U-shaped needle-carrier 11 provided with an opening 11:: in its web while its trapeziumshaped flanges are provided at their ends with projections 11b extending along the inner surface of the outer wall of the container to either side of the slot 61).
The loading of the container is obtained by first inserting each of the injection needles in a needle-carrier 11, the hollow needle shank being introduced through the flanged side of the carrier into the opening 11a. The needle-carriers 11 thus provided each with a needle are then superposed along the slot 6b of the container 6 after shifting the slider rearwardly, so as to allow their introa 3 duction through the slot section 60 at the upper end of the slot 6b. The flange projections 11b directed inwardly of the needle-carriers are held against the inner surface of the front wall of the container so that said carriers are held fast horizontally inside the slot 6b. The slider 89 is'then urged into its closed position and the container loaded in the manner described is introduced radially inside the drum 2 of the washing machine. In this condition, the containers engage through the recesses 6a, at the inner ends of their upper and lower walls, the corresponding rods 4 f the rod cage.
Lastly, annular members 12 illustrated in FIG. l are inserted in the drum 2 so as to rest through their inner surfaces on the corresponding outer upper and lower edges of the carriers 6 while their outer surfaces engag the drum wall.
When the drum revolves at the desired rotary speed, the containers 6 and also the needles fitted in their carriers 11 are subjected to centrifugal action. The needles floatingly carried in the containers retain their horizontal radial direction as illustrated in FIG; 1.
On the other hand, the containers are filled speedily with the washing liquid passing out of the longitudinal slots 3b of the feed pipe 3, so that a liquid column is formed in said pipe under the action of centrifugal force; the high pressure of said liquid column is applied to the liquid urged through the inside of the-needles and the bores in said needles are thus perfectly cleaned.
FIGS. 6 and 7 show a needle-carrier 13 in the shape of a hollow rectangular bar and adapted to receive a large number of superposed needles. To this end, there is provided in the front transverse wall and in the rear transverse wall'of said carrier a longitudinal slot, 13a or 131), respectively, open at its upper end,.the-rear wall slot being somewhat broader than the front wall slot. The actual needles are introduced through the upper end of the carrier so that the connecting nipples of the needles 7 are laid in superposition inside the broader slot 13b while the hollow needle shanks extend freely through the narrower slot 13a. The container 14 for such a needle-carrier is also open at its front end, as illustrated in FIG. 5. The side walls of said container 14 are'double, the two inner wall sections defining cross-sectionally a chamber which is somewhat narrower at its front end, said narrower front'end of the container chamber 14 broadening again at its extreme front to form a space limited between parallel lateral wall elements and inside which the needle-carrier 13 provided with its needles is inserted with an accurate fit, as illustrated in FIG. 5.
Furthermore, one of the two side walls of the container 14 is provided at its inner edgewith an outwardly bent marginal section 15 forming a reinforcement and hindering any projection of water into the gaps between the successive containers introduced into the drum, as apparent from inspection of FIG. 2.
