Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the technical field of medical devices, and particularly relates to an intelligent vein protection device for blood internal medicine chemotherapy patients. BACKGROUND
[0002] As a long-term and safe intravenous infusion channel, Peripherally Inserted Central Catheter (PICC) has been widely used in the treatment of blood internal medicine chemotherapy patients. Blood internal medicine patients often need to undergo multiple courses of chemotherapy, and most of the chemotherapy drugs are irritating. If they are directly infused through peripheral small veins, complications such as phlebitis and drug extravasation are easily caused. PICC can directly deliver drugs to central veins, and by virtue of the characteristics of fast blood flow and large blood volume of central veins, the chemotherapy drugs can be rapidly diluted, which greatly reduces the stimulation of drugs to blood vessels and provides a safe and effective treatment channel for patients. However, from the perspective of patient's daily activities, the PICC catheter is prone to displacement or even dislocation when the patient is in normal daily activities such as dressing, eating, light exercise, or accidentally collides with external force. More seriously, the pulling of external force may cause damage to the blood vessels, causing complications such as pain and bleeding, which not only affects the treatment process of the patient, but also brings physical pain and psychological burden to the patient.
[0003] Traditional PICC catheter protection devices can only play a simple fixing role. In terms of buffering performance, they lack effective buffering structure design and cannot well disperse and absorb impact force when subjected to external impact, making it difficult to cope with external impact caused by daily activities or accidental collisions. The protection effect on the PICC catheter is very limited. Moreover, when infusion operation is performed, the catheter interface position fixed by the traditional protection device is often not convenient, and medical staff need to spend a lot of time and effort to adjust the catheter position, which brings certain difficulties to nursing work and reduces the efficiency of nursing work.
