Description
Technical Field
The utility model relates to the technical field of medical care, in particular to a wearable internal jugular vein puncture positioning measuring instrument.
Background
The internal jugular vein puncture tube can rapidly open a large vein channel, is convenient for rescuing treatment such as infusion and blood transfusion, can monitor central venous pressure, guide clinical fluid infusion quantity, can also carry out intravenous infusion hypotonic, hypertonic and stimulatory solutions, avoids uncomfortable feeling of patients, can adopt internal jugular vein puncture tube for long-term fluid infusion and patients with poor peripheral vein conditions, can realize intravenous radiography or intravenous interventional treatment simultaneously, can also realize the internal jugular vein puncture tube, such as common filter implantation, release of a vein stent and the like.
The common indications of the cervical catheter are mainly applicable to coma, hemorrhagic shock, massive blood transfusion, blood exchange and the like. In addition, intravenous infusion of hypertonic fluid, puncturing of the internal jugular vein is advantageous because, in particular, the internal jugular vein on the right side is relatively fixed in anatomical position, the body surface markers are relatively obvious, and simultaneously, the internal jugular vein on the right side has a short and straight stroke for entering the superior vena cava, is also convenient for performing catheterization in the right heart chamber, and has a relatively high success rate.
In summary, the internal jugular vein puncture technology has wide clinical application, and particularly has important roles in emergency rescue work. The traditional body surface anatomical positioning internal jugular vein puncture has the characteristics of rapidness, convenience and the like, but has a certain failure rate, and also brings serious complications, such as false puncture of internal carotid artery, hematoma, nerve injury and the like, and particularly for patients with coagulation dysfunction, the incidence rate of false puncture of common carotid artery when experienced persons puncture internal jugular vein is 4% -7%. For patients at high risk or with predicted difficulty in puncture, ultrasound guided downstream internal jugular venipuncture is often used. However, the bedside ultrasound equipment is expensive, high in precision and easy to damage, many departments are not equipped with bedside ultrasound equipment, and the skilled use of the bedside ultrasound equipment requires specialized training and can be mastered by long-term ultrasound clinical experience accumulation. Therefore, certain risks and operation difficulties exist for the pure body surface anatomy positioning of internal jugular venipuncture and some patients with high risk or predicted puncture difficulty.
In addition, in the traditional internal jugular vein puncture, the patient is required to lie on the back and lift the head to expose the outline of the sternocleidomastoid muscle after sitting on the back in operation, and the patient needs to keep the head side to incline and lean backwards continuously in the process to maintain a fixed posture, so that muscle fatigue can be caused for a long time, the coordination degree is reduced, and puncture failure is easy to cause. Meanwhile, for patients with unclear consciousness or unconscious disturbance, the head and neck cannot be matched with the fixed puncture body position to operate, so that the internal jugular vein puncture catheter is difficult to use.
Therefore, in order to successfully perform the internal jugular vein puncture, two conditions need to be satisfied, one is accurate positioning of the puncture position, and the other is to ensure that the patient can continuously maintain the required posture, but the prior art does not have a device capable of realizing the function, namely the research and development of the device becomes a technical problem to be solved urgently.
