Description

Emitter capable of adjusting implantation depth

Technical Field

The utility model relates to a blood sugar continuous monitoring field especially relates to a transmitter of adjustable implantation depth.

Background

The subcutaneous implanted continuous blood glucose monitoring system (CGMS) can be used as a beneficial supplement or even a substitute for the traditional blood glucose monitoring product, provides the map information of blood glucose change and reduces or avoids pain caused by finger blood collection of a patient. CGMS is a monitoring technology that reflects the blood glucose level by monitoring the glucose concentration in the interstitial fluid of the subcutaneous tissue using a glucose sensor, can provide continuous and comprehensive blood glucose information, can visually compare it with a "blood glucose electrogram", is similar to an electrocardiogram, can obtain a blood glucose fluctuation map of a patient during wearing, and is a tool for understanding the relationship between factors such as food type, exercise type, drug variety, mental factor, lifestyle and the like and blood glucose fluctuation of the patient, helping to formulate an individualized treatment scheme, improving treatment compliance, and performing visual diabetes education.

CGMS generally consists of a GOx-based "needle-type" electrochemical glucose sensor that can be implanted subcutaneously in a human body with minimal trauma, a set of wireless or wired signal detection and transmission/recording devices (transmitters), and an algorithm (usually placed in an App or receiver) that converts the detected current signal into glucose concentration, often with the need for a needle assist device to implant the sensor subcutaneously. The sensor (i.e. the probe) is penetrated into the subcutaneous part by the needle assisting device, the sensor forms an electric signal when the sensor is oxidized and reacts with glucose in the body in the tissue fluid of a patient, and the electric signal is converted into a blood glucose reading and then transmitted to the receiver by the transmitter. Under the guidance of the data and the visual chart, a clinician can comprehensively understand the 24-hour blood sugar fluctuation condition of the patient, and can be matched with an insulin pump to inject insulin to the patient when necessary.

Generally, CGM sensor working electrodes consist of a surface metal layer, an inner layer, an enzyme layer, and an outer membrane. Dissolved oxygen and glucose in Interstitial Fluid (ISF) enter an enzyme layer through an outer membrane, glucose molecules react with the enzyme to generate electroactive reaction products, namely hydrogen peroxide and gluconic acid, the hydrogen peroxide diffuses inwards and outwards respectively, the inwards diffused part reaches the surface of an electrode, electrode reaction is carried out, and electrode current is formed. The current and the glucose concentration have an approximate linear relationship within a certain range, so that the glucose concentration can be converted by the magnitude of the current value.

At present, except that a Dexcom company uses a flexible noble metal alloy wire as a sensor substrate material, other companies basically adopt a flexible substrate material PI or PET, then metallization and patterning are carried out on the flexible substrate material PI or PET to realize preparation of an electrode, a sensor probe is sleeved in a semi-closed needle before implantation, the semi-closed needle wraps the sensor probe and enters the subcutaneous space under the action of a needle booster, the needle booster is taken down, the semi-closed needle is also taken off, and the sensor probe is smoothly implanted into the subcutaneous space.

CGMS can correctly reflect the change of blood sugar of human body, which is based on the assumption that the concentration of glucose in intercellular fluid is very similar to the concentration of blood sugar, and is basically based on the fact that the glucose in tissue fluid derived from capillary vessels of human body has higher correlation with blood sugar, and the current generated by biochemical reaction of glucose in tissue fluid can be converted into blood sugar detection value by referring to the calibration of blood sugar value. This requires that the sensor be closer to the site of capillary abundance, with greater accuracy. Since the CGM sensor is usually required to be implanted into the subcutaneous fat layer, different individuals have different body conditions, different thicknesses of the fat layer and different degrees of abundance of capillary vessels, and different implantation depth adjustment mechanisms are helpful for obtaining the maximum effective area of the sensor and ensuring the sensitivity of the sensor. Human fat generally has both a white and brown color, of which: white fat accumulates under the skin, responsible for storing excess energy, and also forms unsightly fat proud; the brown fat cell contains a large amount of mitochondria and is rich in capillary vessels, so that a brown fat part or a joint of white fat and brown fat is a recommended implantation part of the CGM sensor.

The implantation depth of the sensor in the continuous blood sugar monitoring products which are released in the market at present is not adjustable, so that when a patient with too thick or too thin skin uses the continuous blood sugar monitoring products, the probe of the sensor cannot reach a proper monitoring position, and the accuracy of a test result is influenced.

When the blocking piece 32a is at a certain fixed position, the rotation movement tracks of the clamping ribs 2051 are all above the height of the whole blocking piece 32a or the two are just in contact without interference, and the movement of the clamping ribs 2051 in different grooves 302 and the adjustment of gears are not influenced by the existence of the blocking piece 32 a; after gear adjustment, rotate and block piece 32a, make and block piece 32a and be in between card muscle 2051 and the first cavity 14 lateral wall, at this moment, block piece 32a and can strengthen the combination of card muscle 2051 and recess 302, the unable backward deformation of card muscle, and then can fix bracket 205, the length that makes the probe stretch out the base is a certain fixed length.

In some preferred modes, as shown in fig. 16, the bottom of the adjusting locking piece 3a is provided with a handle 31a, which is configured to enable the adjusting locking piece 3a to rotate relative to the base 3 by dialing the handle 31 a. Correspondingly, the lower bottom surface of the base is provided with an open slot 26a, and in some preferred modes, as shown in fig. 18, the open slot 26a is an arc-shaped slot, the handle 31a can move in the arc-shaped open slot 26a, and the adjusting locking piece 3a can rotate relative to the base 3 along with the movement of the handle 31 a. In some preferred forms, the bottom surface of the handle 31a is flush with the bottom surface of the base 3 or the bottom surface of the handle 31a is located above the bottom surface of the base so as not to interfere with the engagement of the base 3 with the skin surface.

In some preferred forms, as shown in fig. 18-21, the slot 26a has two extreme positions, a leftmost position and a rightmost position, the leftmost position being a locking position and the rightmost position being an unlocking position. When the handle 31a is stirred to the rightmost end (namely, the unlocking end), as shown in fig. 19, the position of the clamping rib 2051 and the blocking piece 32a does not interfere with each other, at the moment, the blocking piece 32a is fixed in position, the adjustment of the gear can be carried out, in the gear adjusting process, the track of the rotary motion of the clamping rib 2051 is higher than the height of the blocking piece 32a, the existence of the blocking piece 32a does not influence the movement of the clamping rib 2051 in different grooves 302, in the gear adjusting process, the upper cover 1 and the base 3 rotate relatively, the clamping rib 2051 can deform backwards, the jump between the grooves 302 is realized, and therefore the length of the probe extending out of the base can be adjusted. When the handle is shifted to the leftmost end (namely, the locking end) after the required gear is adjusted, as shown in fig. 20, the blocking piece 32a moves between the clamping rib 2051 and the outer side wall of the first cavity 14, the blocking piece 32a abuts against the clamping rib 2051, so that the clamping rib 2051 cannot elastically deform backwards, the clamping rib can be prevented from jumping between the grooves, the upper cover 1 and the base 3 cannot relatively rotate, namely, the length of the probe of the emitter extending out of the base is locked, and the length of the probe extending out of the base 3 is prevented from being changed by other external force; for example, when a user takes off clothes, external force acts on the upper cover, and the depth of the probe penetrating into the skin is changed under an unexpected condition; if the handle 31a is pulled to the locking end, the length of the probe of the transmitter extending out of the base will not change.

In some preferred modes, as shown in fig. 18 and 20, the bottom surface of the base 3 is provided with a locking mark and an unlocking mark, so that a user can conveniently adjust gears and fix gears, the use is more convenient, and the operation is simple.
