Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blood collection, in particular to a blood sampler. Background Art
[0002] As we all know, pediatrics is a comprehensive medical science that studies the physical and mental development, health care, and disease prevention of children. All health and hygiene issues related to children and adolescents fall within the scope of pediatrics. When children are sick, blood sampling is required for testing.
[0003] The patent with application number CN202222864649.0 discloses a blood sampler, including a base, a connecting block is fixedly installed on the top surface of the base; a fixing component, the fixing component is arranged on the top surface of the base and is used to fix the patient's arm, the fixing component includes: a placement groove, the placement groove is arranged on the top surface of the connecting block, a protective pad is fixedly installed on the inner wall of the placement groove, a fixing block is movably connected to the top surface of the connecting block, a mounting groove is arranged on the bottom surface of the fixing block, an air bag is fixedly installed inside the mounting groove, a connecting hole is arranged on the top surface of the mounting groove, an air inlet nozzle is arranged on one side of the air bag, the air inlet nozzle is fixedly sleeved inside the connecting hole, a micro air pump is fixedly installed on the top surface of the fixing block, an air inlet pipe is fixedly installed on one side of the micro air pump, and one end of the air inlet nozzle is fixedly installed on the other end of the air inlet pipe.
[0004] Although the device can fix the patient's arm, the device is only provided with an airbag on the fixing block, and no airbag is provided on the connecting block. When the device is used to fix a child's arm, due to the different physical growth conditions of each person, when fixing a thin arm, the airbag can only fix the upper part of the arm, and the lower sides of the arm are not attached to the inner wall of the connecting block, so the fixing effect is not very good. Secondly, children's arms are of different lengths, and the length of the connecting block cannot be adjusted according to the length of the child's arm. Therefore, for children with shorter arms, their hands will be in the placement groove, and for children with longer arms, their forearms will be on one side of the connecting block, thus being in a suspended state, so the child's forearm cannot be placed in the best position, thereby increasing the discomfort. Therefore, the practicality is not very good and there is room for improvement. Utility Model Content
