Superficial venipuncture auxiliary

Abstract

The invention belongs to the field of medical instruments, in particular relates to simple equipment for assisting superficial venipuncture operation to increase the success rate of superficial venipuncture and cathetering, and aims to solve the problem that the one-time success rate of superficial venipuncture cathetering is low. The equipment starts from controlling blood vessel displacement andoptimizing puncture points and puncture routes, human fingers are replaced by a positioning frame to hold skin to carry out puncture, both ends of a vein to be punctured are extruded by a vein fixingpressurizing component and a vein fixing puncture guide component which are connected with both ends of a puncture auxiliary frame, control on vein movement is achieved, the vein is kept full, secondary vein pressurization in puncture is achieved, the puncture entry point is lower than the surface of skin, and the puncture route is parallel to the middle axis of the vein to be punctured to the maximum extent. The equipment has the beneficial effects that the one-time success rate of superficial venipuncture cathetering is increased, pain of patients can be alleviated, needle pricking wounds can be reduced, the medical security can be improved, and the equipment is small and exquisite in design and applicable to a diversity of situations.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a simple device for assisting superficial venous puncture, so as to improve the success rate of superficial venous puncture and tube placement. Background technique [0002] Superficial venipuncture is a key operation for clinical venous blood collection, intravenous drug administration, and fluid replacement. At present, it is basically done manually by medical staff, and the success rate of one-time puncture varies. As a result, medical efficiency is reduced, patients' pain is increased, and in severe cases, it even affects the harmonious relationship between doctors and patients. Although vein imaging equipment can be used to improve the visibility of veins and improve the success rate of venipuncture to a certain extent, the uncertainty of manual puncture is still unavoidable. The reasons for this uncertainty are mainly due to: 1. The medical personnel use their fi...

This is not only difficult to ensure the accuracy of the puncture diameter, but also has the possibility of needle stick injury

2. The traditional operation emphasizes reducing the angle between the puncture needle and the skin as much as possible to increase the safe advancing distance after the needle tip penetrates into the vein. However, due to the existence of skin and subcutaneous fat, it is difficult to achieve a too small puncture angle, and Causes the puncture needle to travel too long in the skin and subcutaneously, increasing the pain sensation of the patient

It shows that operating experience significantly affects the success rate of a puncture
