Embodiment Construction

[0031] The embodiments of the injection needle automatic selection platform and method of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Injection refers to the injection of liquid or gas into the human body by means of medical devices such as syringes to achieve the purpose of diagnosis, treatment and prevention of diseases. It is not the same as taking medicine. After injection, the drug can quickly reach the blood and take effect. After injection, the drug can quickly reach the blood and take effect. However, in case of misuse, the drug is not easy to remove, there is pain during injection, and local adverse reactions sometimes occur at the injection site. The needle is a hollow metal needle that can be freely loaded and unloaded at the head end of the syringe.

[0033] The current injection control mechanism cannot identify whether the current injection needle size is suitable for the blood vessel width of t...

Abstract

The present invention relates to a platform and method for automatic selection of injection needles. The platform includes: an injection needle used to deliver medicinal liquid to a patient to be transfused, and the opening of the injection needle has a circular shape with a preset radius; a needle selection mechanism , for sending a needle replacement signal when the received maximum physical width of the blood vessel is less than or equal to the preset radius; the needle selection mechanism is also used for when the received physical maximum width of the blood vessel is greater than the preset radius , to send a needle valid signal. The injection needle automatic selection platform and method of the present invention are convenient to control and widely used. Since it can be recognized on the spot whether the size of the current injection needle is suitable for the blood vessel width of the patient to be infused, and the size of the available injection needle is given when it is not applicable, thereby replacing the original rigid injection mechanism of the same injection needle size.

Description

technical field [0001] The invention relates to the medical field, in particular to an injection needle automatic selection platform and method. Background technique [0002] Infusion, or large-volume injection, refers to a large-dose injection that is infused into the body by intravenous infusion, with a single dose of more than 100ml. It is a branch of injections, usually packaged in glass or plastic infusion bottles or bags, and does not contain antibacterial agents. When in use, adjust the drip rate through the infusion set, and continuously and stably inject the medicine into the body. [0003] According to the clinical requirements and the nature of the infusion itself, the infusion has the following characteristics: [0004] 1. The amount of infusion is large, and the requirements for pyrogen, clarity, sterility, pH, osmotic pressure, etc. are stricter than those of small-volume injections, and the pH is close to that of body fluids, so as to avoid overacid and over...
