Description

i

  The subject of the invention is an accessory for repairing

  container for sampling liquid by a hollow needle or a tube. The liquid can be an injectable liquid for injection into humans, animals, fruits or vegetables.

  For many years, farmers have

  routinely administer massive doses by mouth

  of anthelmintics to inhibit the effects of worms

  testins and other parasitic worms in cattle, sheep and pigs. However, these massive doses become effective only after a relatively long time. It has become possible recently to obtain the same

  effect in a much shorter period of time

  killing injections on the animal but the farmers

  reluctantly use new methods. This-

  is due to the fact that it is not customary to sterilize the injection site before or after it and that

  usually uses the same needle to

  injections on a large number of animals without sterilizing the needle before each injection. In addition, when taking the dose directly from a container by inserting the needle into the container, the unsterilized needle can

  contaminate the remaining injectable liquid in the

  tainer. Thus, there is a significant risk of infection of the injection site, leading to abscess. In addition, especially in the case of sheep, there are several

  routine injections administered to arrest di-

  Clostridial complications and each time an animal is injected, this increases the risk of rejection of the carcass for human consumption.

Following abscesses.

  It is known in human medicine to use an injectable liquid container having a self-sealing closure element through which it can be made

  pass the needle to take a dose from the container.

  When removing the needle, the closure element

  automatically seals and thus prevents

  injectable to be contaminated directly by

  ronment. However, it is almost inevitable that the liquid will be more or less contaminated when

  insert the needle into the container.

  An object of the invention is to provide an accessory for an injectable liquid container which has the effect of automatically sterilizing the needle when

  remove a dose from the container. Another goal is to provide

  to create an accessory of this kind which has the effect of

  that the liquid contained in the receptacle is not

contaminated by the needle.

  According to the invention, an accessory intended for a

  container from which it is necessary to remove liquid

  a hollow needle or tube, includes

  yens of sterilization and is designed to adapt to

  container in such a way that the needle or tube passes

  through the means of sterilization and thus be

  rilized when inserted into the container to pre-

lift the liquid.

  Preferably, the accessory is in the form of a

  cap to adapt to a portion of the configuration

  adequate container through which the needle or tube is to be inserted. When the liquid is to be drawn by means of a needle, the cap may be

  fitted over a closure element of the container.

  Thus, if the closure member is of the conventional self-sealing type, the needle can pass through the closure member after having passed through the cap and the closure member automatically assures again

  sealing the container when removing the needle.

  The cap may be provided with a lip pointing towards

  inside to engage under a shoulder of the recess.

tainer.

  The accessory can be divided into several

  compartments separated by one or more partitions, each compartment containing sterilization means. This makes it possible to use the means of sterilization provided for in

249660 '

  a second compartment for sterilizing the needle or the tube when the sterilization means of a first compartment are contaminated. Preferably, several

  partitions move radially outwards in

  both of a common axis and are spaced from equal angles. The invention also relates to a liquid container provided with such an accessory, the accessory being preferably adapted over a closure element

self-sealing container.

  In order for the invention to be more

  understood, will now be described by way of example an embodiment, with reference to the accompanying drawings in which

  FIG. 1 is a vertical section of a blank

  with injectable liquid provided with a cap according to the

  vention; Figure 2 a horizontal section of the cap along the line II-II of Figure 1; and

  Figure 3 a view over the cap.

  The sterilization cap 1 is shown

  adapted to a flexible plastic bottle 2 containing

  injectable liquid 3 and equipped with an

  self-sealing plug 4 of a known type. This last

  takes a rubber-tight piece 5 and a

  metallic water 6 cooperating with an annular flange 7 provided on the bottle 2 to tighten the closure element

4 on the bottle 2.

  The cap 1 is made of plastic

  and comprises a circular upper wall 8 and a

  cylindrical side king 9 heading down from it. The space of the upper region of the cap 1 is divided into three compartments 20, 21 and 22 by three cldsons 10, 11, 12 spaced apart by 1200 as

  clearly seen in Figure 2. Each of the comparisons

  timents contains means of sterilization (not

  such as a sponge impregnated with sterilized liquid

  for example. Or, each compartment can

  contain a sterilizing powder or a sterilizing gel.

  In addition, the cap 1 is fixed to the bottle 2 by an annular lip 13 directed inwards at the bottom of the side wall 9 and engaging under the ring 6 of the closure member 4. The lip can be formed 13 after fitting the cap 1 over the blocking element 4, for example by a heat treatment. Or again, the lip 13 can be preformed

  and the wall. 9 of the cap 1 can be deformed

  ble to allow the lip 13 to fit over the closure member 4 and snap under the ring 6. In addition, the lip 13 may be provided with a ramp surface for it. make it easier to fit over the blocking element 4. A rubber seal 17 is provided between the bottom of the

  partitions 10, 11 12 and the top of the closure element

age 4.

  In order to take from vial 2 a dose of

  injectable medicine 3, it is possible to ensure that the

  the injection syringe penetrates one of three weakened regions 14, 15 and 16 (see Figure 3) of the upper wall 8 of the cap 1 and passes through one of the compartments 20, 21 and 22 containing a substance

  sterilizing. We then make sure that the needle penetrates

  be the seal 17 and the self-sealing element 5 before

  to get into the liquid 3 contained in the bottle 2.

  Once the desired dose has been taken, we can remove

  the needle and the bottle 2 is automatically made waterproof again by the self-sealing element 5, which

  prevents the liquid 3 remaining in the bottle 2 from being

  tampered with the environment. During the introduction process

  duction of the needle in the bottle 2 and its withdrawal,

  the needle is coated with sterilizing substance. This revival

  sterilizes the needle prior to injection and the injection site as part of the

  sterilizing substance on the needle is transferred

  on the injection site. The needle is also

  when it is actually introduced into the

  con 2 and this prevents contamination of the liquid 3 by the needle. When the compartment 20, 21 or 22 of the cap 1 through which the needle has passed is contaminated,

  after taking a number of doses or

  considerable time since the first

  raised, a new dose can be removed by

  so that the needle penetrates another of the

  14, 15 and 16 and crosses another compartment 20,

  21 or 22 containing fresh sterilizing substance.

  Similarly, the sterilizing substance of the third

  compartment 20, 21 or 22 can be used to sterilize

  the needle when the other two compartments are

taminated.

  Although the invention described above in

  the drawings is intended primarily for adapting

  containers filled with injectable liquid to be removed by means of a hollow needle before

  an injection with it, it is understood that a capu-

  sterilizing chon, but with a single compartment

  containing the sterilizing substance, may be

  adapted to a container for a liquid such as glutinous

  that it is a question of introducing directly into the

  the blood supply of a patient. In use, a needle

  placed at one end of a flexible tube is automatically

  sterilized by the cap when inserted into

  container and insert into the patient's arm

  needle provided at the other end of the flexible tube.

  The sterilizing cap can also be used for other applications.

  in which it is necessary to levy a liquid

  of a container by means of a hollow augur.

  In addition, a sterilizing cap variant can be used in applications where it is a question of taking liquid from a container through a thin tube. In such a case, the container is generally not equipped with a self-sealing plugging element, but it is directly plugged

  by the sterilizing cap. In addition, instead of

  one or more weakened regions, the wall

  The upper end of the cap has one or more parts which can be easily removed so as to allow insertion of the tube into the container through the sterilizing cap. As in the case of the needle, the tube is sterilized automatically when it passes through the cap and therefore does not contaminate the liquid

1O of the container.

  Although we use in the description the word

  "sterilize" in the sense of killing microorganisms such as bacteria or viruses, it is understood that it is not essential that all microorganisms be killed, ie that the needle or tube is made

absolutely sterile.
