Description

Sterilization module, medical instrument, and implant including monitoring therapy probe

Technical Field

The utility model relates to a sterilization module, medical apparatus and instruments and implantation device that contain monitoring treatment probe.

Background

Some medical devices require that the monitoring treatment probe portion be implanted in the body for detection or treatment and then the associated signal needs to be processed for communication with the electronics. For example, a monitoring probe such as a blood sugar monitoring sensor, which is implanted into a body and has a monitoring site with a glucolase and other auxiliary substances, and generates an electric signal when chemically reacting with glucose in tissue fluid, and the blood sugar value can be detected by measuring the value of the electric signal; while therapeutic probes, such as neurological therapeutic probes, can release electrical signals when they reach the appropriate location in the body, they can treat or ameliorate neurological disorders such as epilepsy, neuropathic pain, etc. But the relevant parts implanted in the body must be sterilized and then maintained in a sterile state; then monitoring the signal of the treatment probe in a working state, and transmitting and processing the signal with a circuit in the medical instrument; in order to expand the functions or facilitate the use, the medical device itself needs to perform wireless communication with a terminal such as a mobile phone.

Taking continuous blood Glucose Monitoring CGM system (Continues Glucose Monitoring) as an example, the Glucose Monitoring therapeutic probe comprises an in vivo part and an in vitro part; the body part is implanted subcutaneously to detect glucose in body fluids. The enzyme through monitoring position reacts with glucose, produces the signal of telecommunication, and the signal is transmitted to external part through glucose monitoring treatment probe internal conductor circuit itself, and at the implantation subcutaneous in-process simultaneously, glucose monitoring treatment probe's internal part needs the guide needle supplementary, is implanted internal by the guide needle encirclement, and then the guide needle withdraws from, remains the internal part of glucose monitoring treatment probe subcutaneous detection. Glucose monitoring treatment probes and guide needles are strictly sterilized because they require implantation.

The CGM system also comprises a circuit module, the external part of the glucose monitoring treatment probe transmits signals to the circuit module, the circuit module is processed and then carries out wireless communication, and the signals are transmitted to a mobile phone or other terminals. The circuit module needs to be provided with a chip in order to perform complex processing on signals and enable wireless communication.

There are generally two types of medical device sterilization, one is ethylene oxide sterilization, but this affects the enzymes of the glucose monitoring therapeutic probe, thereby causing performance impact; one is radiation sterilization, such as electron beam sterilization, which requires a sufficiently large dose, but the chip of the CGM circuit module is very delicate and sensitive, and large dose of radiation often causes it to be greatly affected.

In order to prevent the fine sensitive device of the CGM system from being affected by the irradiation in the radiation sterilization, it is often adopted to separate the portion to be irradiated and the circuit portion, the irradiated portion (the implanted portion with the monitoring treatment probe) is sealed to form a sterile barrier and is subjected to the irradiation, and the circuit portion is not affected by the irradiation. The two are packaged separately and sent to the hands of the consumer, and the two are combined before or during use by the consumer for use and detection.

In the prior art, because a user needs to recombine the implanted sterilization part and the circuit part, the use convenience of the user is influenced; furthermore, the two-part combination requires additional structure and circuitry, which adds complexity and bulk, as well as increased packaging and shipping costs.
