Injection device, infusion equipment and injection control method

Abstract

The invention discloses an injection device, infusion equipment and an injection control method. The injection device comprises a control module and an injection mechanism which are connected, the injection mechanism comprises a pushing part, a needle head bearing part and a contact plate; a plurality of needle head access holes are formed on the contact plate, a sensor is arranged at the needle head access holes, and the sensor is used for acquiring blood vessel information of a human body; wherein the needle head bearing part comprises a plurality of variable needle heads and a fixing structure used for fixing the variable needle heads, and the control module is used for selecting a target variable needle head according to human body blood vessel information obtained by the sensor and controlling the target variable needle head to be hardened, so that the target variable needle head penetrates through the corresponding needle head access hole. According to the injection device disclosed by the embodiment of the invention, the control module and the injection mechanism are matched to quickly and accurately finish the needle inserting action, so that the error rate of needle inserting is reduced, and the pain caused by needle inserting and the fear of a patient to the needle inserting action are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an injection device, infusion equipment and an injection control method. Background technique [0002] At present, nurses or professionals are required to manually complete the infusion and needle injection when patients are infused. However, infants and young children are in the developmental stage, and the blood vessels are small and difficult to observe. Because of its great sensitivity to pain and intimidation, acupuncture brings great psychological trauma and shadows to infants and young children, and there are certain safety hazards in the process of head and foot infusion. At present, in order to reduce this hidden danger, more Mechanical immobilization restricts the movement of their local limbs, which makes infants extremely uncomfortable during infusion, which leads to crying and fear of infusion.

Problems solved by technology

[0002] At present, nurses or professionals are required to manually complete the infusion and needle injection when patients are infused. However, infants and young children are in the developmental stage, and the blood vessels are small and difficult to observe. Because of its great sensitivity to pain and intimidation, acupuncture brings great psychological trauma and shadows to infants and young children, and there are certain safety hazards in the process of head and foot infusion. At present, in order to reduce this hidden danger, more Mechanical immobilization restricts the movement of their local limbs, which makes infants extremely uncomfortable during the infusion process, leading to crying and fear of infusion

[0003] At the same time, some adults have inconspicuous blood vessel positions due to obesity or long-term infusion. During infusion, it is difficult to determine the position of blood vessels, resulting in multiple needle injections, causing psychological harm to patients.
