Problems solved by technology

However, this kind of equipment is essentially an advanced imitation of manual venipuncture, and it still cannot get rid of the dilemma of insufficient venous filling faced by manual puncture, so it cannot ensure a successful puncture
And this type of equipment is currently only designed to solve venipuncture blood collection, does not have the function of venous catheterization, and cannot meet the needs of clinical infusion therapy

Embodiment Construction

[0019] The invention discloses a deterministic blood vessel puncture and catheterization method and device. The device is composed of five parts: an ultrasonic detection component, a negative pressure control component, a skin poking component, a blood vessel wall control component and a blood vessel puncture component.

[0020] Take the dorsal vein puncture catheter as an example. First, determine the vein to be punctured by manual or auxiliary ultrasound probe, disinfect the skin, and determine the puncture position along the direction of the vein. The skin lifting patch is applied, the skin is pulled by the skin lifting device to increase the distance between the skin and its deep blood vessels, and the skin is pierced through the short puncture needle to avoid damage to the vein to be punctured. Apply ultrasonic coupling agent to the side gap formed by the non-adhesive part of the lifted skin patch and the edge of the skin, place the ultrasound probe here to monitor the subse...

Abstract

The invention belongs to the field of medical devices, in particular to an operation method and device for improving the success rate of vascular puncture and catheterization at one time. In order tosolve the problem of low success rate of puncture and catheterization caused by insufficient blood vessel filling. A method for puncture skin includes such step as puncturing skin and blood vessel, separating skin and blood vessel with lifting and pulling skin paste film, and using short stab needle to avoid injury of blood vessel when skin is punctured. With the aid of ultrasonic monitoring and pressure monitoring, the suction fixed catheter controller and suction fixed catheter with C-shaped cross section were used to actively control the vessel wall by suction under negative pressure to optimize the puncture diameter. The puncture needle is guided to complete the blood vessel puncture and catheterization through the suction fixation catheter C-shaped semi-embracing channel. The invention has the advantages that the certainty of successful vascular puncture and catheterization is greatly improved, and the medical safety is improved.

Description

Technical field [0001] The invention belongs to the field of medical devices, and specifically relates to an operation method and equipment for improving the one-time success rate of blood vessel puncture and catheterization. Background technique [0002] Vascular puncture is the key operation of clinical blood collection, vascular administration and fluid rehydration. At present, it is basically done manually by medical staff. In most cases, experienced nurses can successfully puncture at one time, but for infants and young children, scalp vein puncture, hemorrhage, shock, etc. In critically ill patients with venous collapse due to circulatory failure, the success rate of manual puncture is greatly reduced, and even the skin needs to be incised to expose the blood vessel puncture. The result is reduced medical efficiency, increased patient risk, and harmed the harmony between doctors and patients. The main difficulty lies in the insufficient filling of the blood vessels and the...
