Pediatric external jugular vein blood sampling fixing device

Abstract

The invention provides a pediatric external jugular vein blood sampling fixing device, and relates to the technical field of medical equipment. The pediatric external jugular vein blood sampling fixing device includes a support necklace, a corrugated plate is fixedly connected to the middle of the supporting necklace; a notch is formed in the left side of the supporting necklace, connecting rods are fixedly arranged on the left side and the right side of the notch, first sawteeth are formed in the inner sides of the connecting rods, the peripheries of the connecting rods are sleeved with sleeve plates, gears are rotatably connected into the sleeve plates, and first rotary knobs are fixedly arranged in the centers of the gears. With the pediatric external jugular vein blood sampling fixingdevice, the neck of a patient can be supported, so the neck of the patient cannot be bent or rotated, the needle inserting difficulty is lowered, the blood sampling success rate is increased, a traditional mode making the patient cry is abandoned, jugular veins of the patient can be fully exposed, blood sampling is facilitated, and pain of the patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a fixing device for children's external jugular vein blood collection. Background technique [0002] Blood collection is to test the patient's blood to make blood samples, while venous blood collection is a method of drawing a certain amount of venous blood through a needle tube, mostly superficial veins located on the body surface, such as elbow veins, dorsal veins of the hand, internal ankle veins or femoral veins. Veins, etc., while children often use blood from the external jugular vein, and it is necessary to puncture the patient's neck vein to get blood. [0003] However, due to the small veins in children, blood collection from the external jugular vein itself is difficult, and during the blood collection process, due to the young age of the patient, the body will twist, which greatly increases the difficulty of needle insertion. It is easy to penetrate the vein...

AI Technical Summary

Problems solved by technology

[0003] However, due to the small veins in children, blood collection from the external jugular vein itself is difficult, and during the blood collection process, due to the young age of the patient, the body will twist, which greatly increases the difficulty of needle insertion. It is easy to penetrate the vein, cause hematoma, and make the child suffer more pain. In order to fully expose the jugular vein of the child and facilitate the needle insertion, the traditional method is to make the child cry as much as possible, but when the child cries In the process of crying, the emotions will become more agitated, making the muscles tense, which is not conducive to the blood collection, and in the process of crying, the body will twitch, which increases the stimulation of the needle to the skin
