Description

Receptor physiological parameter measurement system
Technical Field
The invention relates to a system for quickly implanting a biosensor into receptor tissues, repeatedly using and measuring physiological parameters of receptors, belonging to the technical field of wearable medical appliances.
Background
Some physiological diseases have long disease course and prolonged illness state, and the physiological parameters of the receptor need to be monitored in real time so as to better track treatment. Such as diabetes, require real-time monitoring of the blood glucose of the subject. Accurate blood glucose self-monitoring is a key for realizing good blood glucose control, is beneficial to evaluating the degree of glucose metabolic disturbance of diabetics, and makes a blood glucose reducing scheme, and simultaneously reflects the blood glucose reducing treatment effect and guides the adjustment of the treatment scheme. Currently, the most widely used blood glucose meter is available, and the patient needs to collect finger peripheral blood from himself to measure the blood glucose level at that time. One of the drawbacks of this method is that it is not possible to know the change in blood glucose level between two measurements, and the patient may miss blood glucose peaks and valleys, thereby causing complications and causing irreversible damage to the patient; secondly, the finger tip puncture blood sampling is carried out for a plurality of times every day, which causes great pain to diabetics. In order to solve the puzzles, a method for continuously monitoring the blood sugar of a patient is needed, so that the patient knows the blood sugar condition of the patient in real time and can take measures in time, thereby effectively controlling the illness state, preventing complications and obtaining higher life quality.
In order to solve the above problems, the technical staff developed a continuous blood glucose monitoring technology capable of being implanted into subcutaneous tissue to continuously monitor subcutaneous glucose, the technology comprises a sensor electrode penetrating into subcutaneous tissue, wherein the electrode generates an electric signal when the interstitial fluid of a patient and glucose in the body react, the electric signal is converted into blood glucose readings through a transmitter, the blood glucose readings are transmitted to a wireless receiver every 1-5 minutes, and corresponding blood glucose data are displayed on the receiver and a map is formed for reference of the patient and doctors.
Currently, subcutaneously implantable continuous blood glucose monitoring sensors typically employ very thin wires or polymer sheets as carriers. The wire may be a platinum coated stainless steel wire, for example, the use of platinum electroplated onto a stainless steel wire having a diameter of 0.16mm to 0.25mm as a carrier for the sensor electrodes has been disclosed in the literature. Because the stainless steel wire has sufficient hardness, the sensor electrode can directly penetrate the skin into the tissue without the aid of an auxiliary tool. However, the implantation method has the defects of larger wound, strong pain feeling and strong abnormal feeling after subcutaneous implantation due to larger hardness of the sensor electrode, and still causes great trouble to diabetics.
In order to reduce the pain caused by the sensor electrode, the technician changes the metal wire carrier into a relatively soft platinum wire or a nickel wire coated with platinum, or adopts a polymer sheet as the carrier. However, since the carrier has insufficient rigidity, it cannot directly pierce the skin, and thus it is necessary to implant a small and soft sensor electrode into subcutaneous tissue by means of an auxiliary implantation tool to reduce the sense of presence or abnormal sense after subcutaneous implantation.
Currently, many auxiliary implantation tools are either manual or semi-automatic. Because of inconsistent implantation speed and force of manual implantation, the speed is low, and the implantation process takes a long time. On one hand, the deviation value of the sensor after implantation is larger, and on the other hand, pain of a patient is increased.
On the other hand, the traditional dynamic blood sugar transmitter mainly comprises three parts, namely a button cell, a circuit board and a plastic package shell. Because of waterproof requirements and volume limitations, button cells and circuit boards are generally placed in the emitter together, and are generally molded integrally, the emitter cells are not replaceable. When the battery life is over, the transmitter is essentially unusable. From the cost perspective, the cost of the plastic package shell and the circuit board of the transmitter is far greater than the cost of the battery, and the service lives of the plastic package shell and the circuit board of the transmitter are also far greater than the service life of the battery. From the environmental point of view, the manufacturing and disposal processes of the circuit board may bring potential harm to the environment. Therefore, the mode can greatly waste the circuit board and the plastic package shell, and increase the material cost and the resource waste.
In order to solve the above problems, on the one hand, a proper way is needed to make the small and soft biosensor electrode penetrate into the skin with the help of the auxiliary implantation tool at a very fast speed, so that pain is reduced to a very low level, and the sensor electrode is left under the skin, so that the implantation actions are performed in the set needle tube, and the deviation risk caused by manual operation is reduced. On the other hand, a proper mode is needed to separate the battery from the emitter, so that the service life of the circuit board and the plastic package shell is not limited by the service life of the battery, and the method is very significant in reducing cost and waste.

Detailed Description
The inventive method of the present invention is described and illustrated in detail below in conjunction with specific examples. The content of which is to be interpreted as an explanation of the invention and not to limit the scope of the invention.
Fig. 1 is a schematic diagram of the working principle of the present invention. With the single use implant 200, the sensor 301 is partially implanted into the recipient tissue 100, with the outer recipient portion of the sensor 301 in electrical contact with the emitter 400. After the transmitter detects the bio-signal of the sensor 301, the signal is converted into a physiological parameter and sent to the receiver 500 of the user by means of wireless transmission.
The physiological parameter measuring system is structurally divided into 3 parts: an implanter 200, a sensor mount apparatus 300, and a transmitter 400, as shown in fig. 2.
As shown in fig. 3, in an initial state, the sensor base assembly 300 and the implanter 200 are coupled together by frictional resistance between the guide needle 213 and the silicone mount 310, maintaining their initial positions; the biosensor electrode is mounted inside the implanter, maintaining its initial position by frictional resistance. The transmitter 400 is now in an unused state.
As shown in fig. 4, after implantation, the sensor 301 is partially advanced into the recipient tissue and partially retained in the sensor mount assembly 300. After the transmitter 400 is installed, the transmitter "reads" the signal on the biosensor and converts the signal into a physiological parameter, and sends the physiological parameter to the receiver 500, where the receiver 500 may be a mobile phone, an operator, or even a cloud.
The implant device 200 is described in detail below;
the implanting device 200 is used for implanting a sensor 301 into a recipient tissue, as shown in fig. 5, structurally mainly comprises an upper implanter cover 201, a lower implanter cover 202, a button 203, a bracket 204, a top needle holder 205, a puncture needle holder 206, a guide needle holder 207, a needle return spring 208, a driving spring 209, a thimble 211, a puncture needle 212, a guide needle 213 and a guide stopper 214, wherein the upper implanter cover 201 and the lower implanter cover 202 form an outer shell, the bracket 204 and the guide stopper 214 are fixed in the outer shell, the top needle holder 205, the puncture needle holder 206 and the guide needle holder 207 are all positioned in the bracket 204 and the guide stopper 214, and the top needle holder 205 mainly drives the thimble 211 to move forwards to trigger the guide needle holder 207 to move reversely, so that the implanting process of the sensor 301 is formed.
As shown in fig. 6, a T-shaped structure 2011 (limit structure) is disposed in the upper cover 201 of the implanter, and is used for limiting the guide needle seat 207 and preventing the guide needle seat from shaking, so that the puncture needle can have a relatively straight puncture into human tissue, and pain caused by shaking is reduced.
The implant upper cover 201 is internally provided with a stop 2012 which cooperates with a stop 2041 on the bracket 204 to provide sufficient strength to the bracket stop on the one hand and to prevent displacement of the bracket under the influence of the drive spring 209 on the other hand.
The front end of the implanter upper cover 201 has a button hole 2013 for receiving the button 203. The button can rotate in the round hole and move up and down.
The button hole 2013 has an L-shaped notch 2014 on both sides, and the notch 2014 can be matched with a button boss 2031 on the button 203. In one aspect, the notch may limit movement of the button to the outside of the implanter cover 201 by the button boss 2031. On the other hand, the L-shaped structure can provide a locking and unlocking function. In the initial state, the button boss 2031 on the button 203 is located at the innermost side of the L-shape. The button is limited to rotate in only one direction and cannot be pressed. In this case in the "locked" state. Functions to prevent false triggering of the button 203. When the button is rotated by the user by a certain angle, the button boss 2031 is located at the open end of the L-shape. In this case in the "unlocked" state, the button may be pressed.
The L-shaped notch 2014 has a lock tab 2015, and when the button tab 2031 on the button 203 is in the "locked" position, there is some interference between the lock tab 2015 and the button tab 2031, so the button 203 cannot easily rotate to the "unlocked" position. It is possible to prevent the false triggering of the button 203 in the case of transportation, picking and placing, and the like.
The lower implanter cover 202, as shown in fig. 7, has a base recess 2021 at the bottom, the base recess 2021 being used to mount the sensor base 302, and the sensor base assembly 300 and the implanter 200 are connected together by frictional resistance between the guide pin 213 and the silicone mount 310 to maintain their initial positions before the sensor 301 is implanted.
A triangular rib 2022 is provided in the base recess 2021, and is used to limit the base and prevent the base from moving.
A rectangular opening 2023 is arranged in the base groove 2021, and the opening is moderate in size; in the initial state, the opening allows the swivel seat 309 in the base to pass, but restricts upward movement of the base.
