Problems solved by technology

[0006] A disadvantage of current systems for subcutaneously inserted sensor systems is that they may require the use of inserts each time the sensor is inserted into the patient
A further disadvantage of the current system is that often large volumes and a large number of packages are used

Embodiment Construction

[0049] Like numbered elements in these figures are either equivalent elements or perform the same function. Elements that have been discussed previously will not necessarily be discussed in later figures if their functions are equivalent.

[0050] figure 1 An example of a sensor cartridge according to the invention is shown. There is a package 102 forming a sterile capsule 104 . Inside the sterile capsule 104 is an insertion needle 106 . Also within the sterile bladder is a sensor 108 located within the lumen of the insertion needle 106 . There is a sensor mounting unit 110 forming the bottom portion of the sterile bladder 104 . The sensor mounting unit 110 has a hole 112 through which an insertion needle 106 can be inserted into a patient 114 . The sensor mounting unit 110 has an adhesive surface 116 in contact with the patient 114 for attaching the sensor mounting unit 110 to the patient 114 . Also within the sterile bladder 104 is an insertion mechanism 118 for actuat...

Abstract

The invention provides for a sensor cartridge (100, 400, 500, 800, 900, 1000, 1300, 1400, 1500) comprising a sterile capsule (104). The sensor cartridge further comprises a sensor (108) within the sterile capsule. The sensor cartridge further comprises a sensor connector (120) connected to the sensor in an initial position (122). The sensor cartridge further comprises an insertion needle (106) for inserting the sensor into a subject (114). The insertion needle is within the sterile capsule. The sensor cartridge further comprises a sensor mounting unit (110) for receiving the sensor connector at a mounted position. The sensor mounting unit comprises an adhesive surface (116) for attaching to an exterior surface of the subject. The sensor cartridge further comprises an insertion mechanism (118) operable for actuating the insertion needle and moving the sensor connector from the initial position to the mounted position.

Description

technical field [0001] The present invention relates to sensors for monitoring analytes in vivo, and in particular to devices for inserting sensors into patients. Background technique [0002] For proper management of a long-term medical condition, it can be critical for a patient to periodically monitor the level of one or more analytes in his or her bloodstream. In the case of diabetes, patients routinely monitor glucose levels to avoid hypoglycemia and hyperglycemia. For other situations where health monitoring is important, other analytes can be measured, such as lactate or oxygen. [0003] A typical arrangement for implementing such monitoring is through repeated blood draws from the patient to provide samples for analysis by the monitoring system. This provides a cost-effective way of monitoring long-term diseases such as diabetes, but it can be inconvenient and only provides data on analyte concentrations for the time interval when the test is performed. [0004] S...
