Definitions

• the present invention refers to a matrix for injection as an auxiliary to avoid repeated injections on the same spot during a rather long period of time.
• the patient is bound to inject a drug daily and incertain cases several times daily. Diabetes is such a disease for which insulin has to be injected daily, and the patient is usually instructed by the doctor or the nursing staff not to make the injection on the same spot at less interval than one month. This for avoiding dystrophies such as cavities, indurations and witherings, with an impaired resorp ⁇ tion of insulin as a consequence. Especially patients who are old, forgetful and shaky in the hands have difficulties in following this recommendation from the doctor, and the injection has therefore hitherto been carried out "to the best of ability", which has had as a consequence in most cases that only -a limited area of the skin has been used for the injection with disregard to the fact that the same area of skin needs substantial time for recovery.
• the purpose of the present invention is to bring about an auxiliary for patients of the abovemen- tioned kind, with the help of which the patient is given a possibility in a guaranteed simple and safe way daily to change the spot for injection during several months so that the tissue can recover and side effects are prevented.
• This problem has been solved by the fact that the matrix for injection forms a bandshaped, flexible cuff of rubber, soft plastic or elastic woven material or the like, and that the cuff has a number of holes arranged in succession, and that the cuff has a quickfixing ° device attached to it made for loosable fixation of one of the bandformed ends of the band thus cre ⁇ ating a closed loop around a part of the body.
• Picture 1 shows a lateral view of the matrix for injection in accordance with the invention proper ⁇ ly placed for use around a thigh.
• Picture 2 shows the matrix for injection according 0 to picture 1 viewed from above.
• Picture 3 shows on a larger scale a section through part of the matrix, just in front of a number of holes and
• Picture 4 shows in perspective the fixation device 5 for tight locking of one of the bandparts of the matrix for injection.
• the matrix for injection forms a bandshaped, flexible cuff 1 of rubber, soft plastic or elastic woven material or the like.
• the bandshaped cuff is at its one end end rather wide and equipped with a number of holes 2 and at the other end shaped as a thinner bandpart 3, ' which is intended to cooperate with a fixation device 4 attached to the wider bandpart in such a way that when the thinner bandpart 3 is put through the fixation device 4 a close loop is made.
• the holes of the matrix are arranged in a suitable number - in the specimen shown 16 - for example of three files symmetrically arranged along a median line A through the middle file of holes.
• indication lines at half distance from the median line A and through which it is easy to see how much the cuff has to be moved - for instance half a file - for getting new injection positions for the matrix and as a result new spots for injection.
• the locking device 4 is of type snaploek and con ⁇ sists of a holder 5 and an excentrically pivoted snap part 6, which together with the friction device 7 with the help of a handle 8 can be twist ⁇ ed closer or further away from the holder 5.
• a bandpart 3 that is put through the space between the snap part 6 and the holder 5 can consequently be fixed fast and easily in the desired position.
• the holes 2 of the matrix are arranged edge supports 9 forming peripheral upsets. These have the function to strap the tissue under the matrix when the matrix is strapped around a thigh, for instance, resulting in dome-shaped tissue cushions being pressed up through the holes. These elevations 'simplify the perforation of the skin area by the needle, whereby the sensitivity reduces and the re ⁇ sorption of insulin is promoted.
• the holes arranged in files are numbered correspond ⁇ ing to the days of the month, and as the thighs of both legs can be used for injection alternately, sixteen are enough. This means that every hole has two figures, where hole numer 1 has also been given the number 16, hole number 2 also the number 17, etc. The remaining sixteenth hole is only for the 31st day in months with 31 days.
• the matrix can be moved for instance half a file distance to the indication lines B or C, so that the spots for injection from the preceeding interval will be protected by the matrix. In this way you will get intervals of three months, i.e. the same area of skin will be the object for injection first after three months, so that a guaranteed recovery of the tissue is achieved. If you move the matrix half a file distance upwards on the thighs you will get the same pattern of injection with spots for injec ⁇ tion that have restedfor three months.
• the left and right thigs should be used interactively.
