Description

A deep vein puncture bag with a sharp instrument insertion structure

technical field

The utility model relates to the technical field of medical instruments, in particular to a deep vein puncture bag with a sharp instrument plug-in structure.

Background technique

Deep vein puncture is a necessary technique for establishing venous access in critically ill patients. The purpose is to: (1) understand the comprehensive situation of effective blood volume, cardiac function and peripheral circulatory resistance; (2) identify acute circulatory failure of unknown cause; (3) observe the dynamic changes of blood volume when a large amount of blood transfusion and fluid replacement is required. The risk of load; ④ for critically ill patients, major operations and emergency situations as a way of massive blood transfusion and fluid replacement.

Deep venous puncture catheterization is to use a puncture needle to guide a special venous catheter to be placed in the deep venous lumen through skin puncture, through which the venous catheter can be used for infusion and measurement of central venous pressure. It has many advantages, such as long time, fast infusion speed, wide infusion type and convenient nursing.

During internal jugular vein puncture and cannulation, the patient needs to lie supine, remove the pillow and tilt the head, turn the head to the opposite side, raise the shoulders if necessary, and lower the head 15-30°. The patient's neck was sterilized with a hole towel, a sterile hole towel was laid, and the puncture point was locally anesthetized. First use a syringe to locate and try on it, and then puncture after determining the position. The left hand holds the designated point, and the right hand holds the puncture needle. The medical staff pushes the syringe to insert the puncture needle into the patient's neck vein, and then removes the syringe. A guide wire with a diameter smaller than the inner diameter of the puncture needle is inserted into the vein from the through hole in the puncture needle, then the puncture needle is removed, and the catheter is threaded into the patient's vein through the guide wire, thereby completing the entire internal jugular vein puncture.

At present, in the process of internal jugular vein puncture, the positioning needle used for positioning and try-on is pulled out from the position of the patient and placed directly into the box, and the puncture needle after puncture is also directly put into the box. At the same time, the dermatome used to break the skin will be directly put into the box. After the medical staff completes the entire process of puncturing the internal jugular vein, the positioning needle, puncture needle and dermatome put into the box will be retracted. Treatment, because the positioning needle, puncture needle and dermatome are exposed, medical staff are easily stabbed by the positioning needle, puncture needle and dermatome during the recovery process. There is a great potential safety hazard, which brings great inconvenience to the recovery of sharps after internal jugular vein puncture.
