Description

A kind of anti-hardening insulin pen

technical field

The patent of the invention belongs to the field of electronic technology, in particular to an anti-hardening insulin pen.

Background technique

Diabetes is one of the four diseases that are more harmful to humans. According to the World Health Organization, there are as many as 200 million people with diabetes, and the number of patients is still on the rise. For diabetes treatment, stable blood sugar control is a very important indicator. Very serious complications can occur due to poor blood sugar control.

There are two commonly used means of oral medicine and insulin injection for the treatment of diabetes. Insulin therapy is required in most cases, especially type 1 diabetes patients basically need insulin therapy; most type 2 diabetes patients also need insulin therapy. It can be considered that the insulin method is an ideal treatment plan at present. In most cases, insulin injections must be completed by the patient himself, and more than one injection per day is required. The injection site is limited, and sometimes a lump will form at the injection site. If the patient does not notice it, inject again near the plate agglomeration , so that the liquid medicine cannot be absorbed, and it also brings great pain, and in serious cases, it will increase the risk of injection needle breakage. Clinically, such cases are numerous. The present invention proposes an anti-hardening insulin pen, with the purpose of avoiding the occurrence of the above events and improving the blood sugar control level and quality of life of diabetic patients.

Contents of the invention

In order to reduce the risk that the existing insulin pen may be in the vicinity of plate agglomeration during injection, an anti-agglomeration insulin pen is provided. The present invention can effectively reduce the risk of injection near plate agglomeration and improve the quality of life of diabetic patients.

The technical scheme adopted by the present invention to solve its technical problems is: the present invention consists of a buffer box, a third connecting arm, a slipknot, a card arm, an insulin injection bottle, an injection needle, a sensing ring, a contact, an injection unit display window, an injection mediation Knob, first connecting arm, fixing ring, insulin injection pen, needle seat, second connecting arm, sliding tube, double connecting piece, spring, fixed joint, pressure sensor, rotating shaft, buffer box shell, buzzer, single-chip microcomputer, It is characterized in that the insulin injection pen is connected with the first connecting arm through a fixing ring, the first connecting arm is connected with the second connecting arm through a buffer box, the second connecting arm is connected with a slipknot through a fixed joint, and the third connecting arm is connected with a rotating shaft. The card arm is connected with the slipknot, the third connecting arm is connected with the sensing ring, the contact is connected with the sensing ring, the sliding tube, double connecting piece, spring and pressure sensor are all in the buffer box, the sliding tube is connected with the buffer box shell, the pressure The sensor is connected with the first connecting arm, the spring is connected with the pressure sensor, the second connecting arm is connected with the double connecting piece through the slide tube, the double connecting piece is connected with the spring, the second connecting arm is connected with the slip knot through the fixed joint, and the third connecting arm is connected with the The rotating shaft is connected, the card arm is connected with the slipknot, the pressure sensor is connected with the single-chip microcomputer, and the buzzer is connected with the single-chip microcomputer.

The inner diameter of the sensing ring is larger than the outer diameter of the insulin injection pen, that is, the front end of the insulin injection pen (the front of the display window of the injection unit) can pass through the sensing ring. Otherwise, insulin injection will be hindered; at the same time, the purpose of effectively avoiding the hardened area can be achieved. The buffer box is cylindrical in shape. The pressure sensor is cylindrical, one end is connected with the spring, it can convert the force of the spring to it into an electrical signal, and send it to the single-chip microcomputer. The pressure sensor is made of silicon piezoresistive integrated sensor. The slipknot is in the shape of a ring, and its middle part is connected with the rotating shaft. The locking arm is in the shape of a cuboid, which is welded with the slipknot, protrudes from the slipknot plane, and is in the same plane as the third connecting arm. The function of the slipknot is to prevent the third connecting arm from reverse rotation, and keep the third connecting arm in a straight line with the first connecting arm and the second connecting arm in the horizontal direction. The sensing ring is a ring structure on which four contacts are evenly distributed. The contacts are cylindrical and made of hard rubber. The fixing ring is a ring structure and is used to fix the first connecting arm on the insulin pen. Insulin injection pens are ordinary insulin pens with a cylindrical shape. The second connecting arm is thin cylindrical. The sliding tube is in the shape of a circular tube and is used to keep the second connecting arm sliding smoothly. The double connecting piece is short cylindrical and is used to fix one end of the spring and connect the contact pin with the second connecting arm. The spring is in the shape of a circular spiral and is made of metal. The stylus is thin cylindrical. The fixed joint is rectangular and welded on the slipknot. The third connecting arm is rectangular.

When injecting insulin, the third connecting arm is first rotated upward (direction away from the injection pen), and then the injection needle is rotated and installed. After installation, turn the third connecting arm downwards (towards the injection pen), and clamp the clamping arm tightly. Adjust the injection volume, and according to the insulin instructions, shake evenly to mix the insulin evenly. To start an insulin injection, bring the insulin pen close to the injection site, with the tips first in contact with the skin. If the injection site is not hardened, the Pen is brought closer to the skin and the tips are pressed into the skin. Since the contact is made of hard rubber, it will not cause damage to the skin. Driven by the forward injection force of the insulin pen, through the fixed ring, the first connecting arm, and the pressure sensor, the spring will exert a pressure on the body, and the skin will generate resistance to the contact, and through the contact, the sensor The ring, the third connecting arm, the slipknot, the fixed joint, the second connecting arm, and the double connecting piece will generate a reverse pressure on the spring to compress the spring, and the pressure sensor will convert this force into an electrical signal and send it to the microcontroller. Compared with the value pre-stored in the memory, because there is no hardening, the resistance is small, so the signal is smaller than the pre-stored limit value, the microcontroller has no signal output, and the buzzer will not sound.

If there is induration at the injection site, the injection pen will approach the skin, and the contact will be subjected to the reaction force of the subcutaneous induration. Driven by the forward injection force of the insulin pen, through the fixing ring, the first connecting arm, and the pressure sensor, the spring will exert a pressure on the body, and the subcutaneous induration will generate resistance to the contact (this force is much greater than When there is no hardening, the resistance of the skin to the contact), and through the contact, the sensing ring, the third connecting arm, the slip knot, the fixed joint, the second connecting arm, and the double connecting piece will generate a large reverse pressure on the spring , so that the spring is compressed, the pressure sensor converts this force into an electrical signal, and sends it to the single-chip microcomputer. Compared with the value stored in the memory, the signal is greater than the pre-stored limit value, and the single-chip microcomputer sends signal, the buzzer sounds an alarm.

The beneficial effect of the invention is to reduce the risk that the existing insulin pen may be near the plate agglomeration during injection. The invention is mainly applied in the field of diabetes treatment.
