Abstract

Particularly for diabetes therapy, it is desirable to continuously infuse insulin in varying installments into the body of the patient. A control device serves as a program transmitter for a microdosing unit. The physician should be able to pre-program the daily profile of the infusion and, if necessary, to change it. According to the disclosure, at least the control device for the microdosing unit has memory means for a prescribable control program allocated to it, whereby the control program is pre-programmable in discrete time steps by an external programming device corresponding with a 24 hour daily sequence. The control device is detachably connected directly with the programming device or is coupled therewith by means of a program carrier or a programmed memory chip solely for a rapid transfer of the pre-programmed control program into the internal memory means of the control device. Thus the control device is particularly adapted for the adjustment of diabetes patients to an optimum daily profile of insulin administration outside of a hospital setting.

Claims

1. In a system for the pre-programmable infusion of liquids into a patient'"'"'s body, the system has a microdosing unit adapted to controllably infuse a liquid into the patient'"'"'s body based on signals received from a patient carriable control unit, the control unit is contained in a housing which includes a memory for storing a dosage control program to control the infusion of liquid by the microdosing unit, an improvement comprising:

a socket part of a two-part means for connection affixed to the housing of the control unit,

data transmission means within the control unit adapted to receive a dosage control program from said socket part of said two-part means for connection and write said program into said memory;

programming means separate from the control unit, said programming means including;

a housing,

a plug part of said two-part means for connection affixed to said housing such that a region of said housing partly surrounds said plug part,

self-containing manually setable means for establishing another dosage control program which extends over a twenty-four hour period, and

means for transmitting said another established dosage control program to said plug part of said two-part means for connection and then to said socket on the control unit only when said socket and plug parts of said two-part means for connection are connected together.
