Definitions
- the present invention concerns a procedure for dispensing a medical substance or another liquid with the aid of a needle into or under a patient's skin, medical substance being conducted from a medicine container with the aid of a pump through a tube attached to one end of the medicine container into the needle.
- the invention also concerns a medicine container to one end of which a tube has been connected.
- the medicine container is appropriate to be used e.g. in conjunction with an insulin pump, in which case the container is filled with insulin in advance.
- the pump may also be used to another purpose, the container then being filled with another medical substance or with a reagent.
- an injection syringe which has been filled with insulin.
- a catheter carrying a needle on its extension To this syringe has detachably been fixed a catheter carrying a needle on its extension.
- insulin for instance, is expelled from such syringes in that a plunger in the container is mechanically depressed and this plunger presses the desired quantity of insulin or other substance into the tube and through the needle in its extension e.g. into the skin.
- the procedure of the present invention is characterized in that the tube is incorporated in a pump, a stopper provided within the container sliding in the container by effect of the vacuum from the pump towards that end of the container on which the tube has been attached.
- the medicine container of the invention is mainly characterized in that on the other end of the container has been provided, with tightly sealing fit, a stopper which is slidable axially within the container.
- the invention is applicable in conjunction with any conceivable type of pump.
- the container of the invention is intended to be single-use, i.e., discardable, in itself. If necessary, it may also be used several times. It can be sterilized as a whole when filled either with medical substance, reagent or another solution, or prior to filling.
- the container can be installed as it is in the pump, and the pumping effect is achieved by installing the tube component of the container in a particular tube pump.
- the container constitutes a part e.g. of an insulin pump, it can be conveniently attached to the pump and upon being emptied, discarded and replaced with another similar container. Most usually this container can be used e.g. in connection with an insulin pump from three to five days, with the consequence that the container's capacity may be such that 100-200 units of insulin can be suitably accommodated therein.
- the container, tube and needle are integral with each other.
- the container with tube and needle is detached from the pump and discarded, and it is replaced with a new container comprising integrally a stopper, tube and needle.
- FIG. 1 presents a means according to the invention
- Fig. 2 presents schematically a means according to the invention, fitted to a tube pump, and
- Fig. 3 shows more closely a detail of the tube pump.
- the medicine container of the invention comprises a container part 1, having as extension on one end a resilient tube 2.
- the juncture 13 of the tube 2 and the container 1 is fixed, and the tube cannot be detached from the container like an injection needle for instance can be detached from the syringe or a catheter from a syringe or equivalent. This makes for greater safety.
- the juncture of the container 1 and tube 2 can be accomplished e.g. by gluing, by ultrasonic welding or by another equivalent procedure. It is to advantage in most instances if the container has been made e.g. by die-casting of a fairly hard plastic material, while the tube consists of elastic material, but one which all the same well retains its calibre.
- the other end of the container part 1 has been closed with a stopper 3, which is enabled to slide in the container freely, but which is free of leakage in spite of this.
- the stopper has been made of a slippery and somewhat elastic material.
- the sliding ability of the stopper has been augmented by providing on the lower rim of the stopper a particular sealing ring 4 and in the top part of the stopper, a guide ring 5, which keeps the stopper accurately aligned with the longitudinal axis of the container. In this instance, the portion 12 between the rings 5 and 6 does not contact the inner wall of the container.
- the tube 2 terminates in a needle 6, which can be pushed into or under the skin.
- a brace 7 has been provided at the junction of needle 6 and tube 2, by the aid of which the needle and tube may be secured to the skin e.g. with adhesive tape.
- a tube pump 8 known in itself in the art, i.e., a peristaltic pump, so that the tube 2 passes trough the pump.
- Fig. 3 has been shown in greater detail a detail of the tube pump.
- the pump comprises a rotating disk 9 carrying rollers 10 onits circumference. As the disk 9 rotates, the rollers 10 squeeze the tube 2 flat at the roller against a cylindrical counterface 11, whereby liquid inside the tube will be pumped towards one end of the tube.
- the stopper 3 of the container follows along with the liquid and moves towards the tube-side end of the container.
- the container of the invention may, if required, be placed inside a protective cartridge or socket so that for instance the stopper in the container cannot inadvertently be mechanically depressed.

Abstract
Procédé et conteneur pour dispenser une substance médicale ou un autre liquide à l'aide d'une aiguille (6) dans ou sous la peau d'un patient. La substance médicale est conduite grâce à une pompe du conteneur de médicament (1) à l'aiguille (6) en passant par un tube (2) fixé à une extrémité du conteneur de médicament. Le tube (2) est incorporé dans une pompe, un bouchon (3) prévu dans le conteneur (1) glissant à l'intérieur du conteneur (1) à cause du vide créé par la pompe vers l'extrémité du conteneur à laquelle a été fixé le tube.
