Intravenous injection acupuncture treatment device

Technical field

This utility model relates to technical field of medical instruments, a kind of intravenous injection acupuncture treatment device.

Background technology

In hemodialysis, internal jugular vein conduit implantation surgery is a common technical operation, in order to set up quick and easy vascular access.Adult's internal jugular vein has 5%～10% anatomical variation, and the vital tissue internal organs such as carotid artery, vagus nerve, trachea are arranged near operative region, has certain difficulty in operating process, and common have complication such as hematoma, oozing of blood, blood drainage are smooth, puncture failure.For patient fat, the cervical region tubbiness, blood vessel may be in desired location or angiostenosis, and blind wearing can be increased the weight of operation risk, and the carotid artery of wearing parallel trend as mistake can cause massive hemorrhage, hemorrhagic shock.What therefore, how to improve success rate of operation, complication is the focus that surgical doctor is paid close attention to.At present, some scholars advises guiding descending conduit implantation in the color doppler ultrasonography instrument, but because the sterilization of color ultrasound indoor sanitation fails to reach the operative region requirement, can not carry out operation technique, and hand propelled color ultrasound instrument is expensive, and need professional image personnel operation, fail extensively to promote in clinical position.Become kidney internal medicine field problem demanding prompt solution therefore seek the other blood vessel positioner of a kind of economical and practical bed by the surgical doctor operation.

In the other mode of being taked the manual probe scanning by surgical doctor of operation table, surveying position at patient's body surface is moved, through the blood flow spectrum analyzer system, process, obtain a series of 3-D views of arranging in order, input to mobile phone or laptop computer, can position detection to blood vessel in real time, to assist dark vein catheterization operation safety, successfully to carry out, improve widely the success rate of operation.Because it is easy to use, it is light and handy, cheap to carry, ten thousand yuan of cost less thaies, can be directly inputted into patient vessel's ultrasonic image in mobile phone or laptop computer, and can set up the corresponding data library storage, is convenient to arrange and analytical information, is easier to use at basic hospital.In use in real time blood vessel is positioned to detection, and image stabilization, for surgical doctor provides a great convenience, can be used as the front routine examination of vascular puncture operation in patients and apply in clinical position.

In order to increase the probability of measuring these two kinds of physiological signals at home, what developed is blood pressure measurement device and the ECG monitoring device used at home, mainly because the operation sequence of these two kinds of physiological signals is all quite simple, convenient and be non-intrusion type, also therefore, there is increasing user can in family, have these two kinds of devices simultaneously.

Can carry out the cardiovascular health of assess patient with blood pressure and electrocardiogram in hospital commonly simultaneously, this be because, blood pressure and electrocardiosignal are the physiological signals be relative to each other, and, by cross-reference between the two, can also reach the effect that removes interfering signal (artifact), noise (noise), in addition, two kinds of signals are after via calculating, also can further obtain the information of relevant cardiovascular aspect, as pulse wave passing time (PTT, pulse transit time) etc., the use of usining as diagnosis.

Therefore, if these two kinds of measurements can combine, can expect more the operation sequence of simplifying, and measurement result more accurately.

At present, blood pressure is that the bandage by being looped around on the user limbs is measured, it is the skin (for example, chest, palm and finger) by making the electrode contact user and carrying out that electrocardiosignal is measured, because bandage must be surrounded on the user limbs, therefore, be quite reasonablely, the ECG electrode is arranged on to the position that this bandage can contact user's skin, as United States Patent (USP) the 5th, 865, No. 761 institute discloses.

Yet utilizing the performed ECG of electrode that is arranged at the bandage surface to measure but has some shortcomings.Owing between skin and electrode, contacting the meeting height correlation in the gas charging degree of bandage, namely, the variation that must occur during blood pressure measurement, therefore, under this situation, reach with skin between stable the contact seem quite difficult, also therefore, may make the accuracy of measurement result be under suspicion.

In addition, general contact electrocardioelectrode is with contact skin the time, also have between contact surface and skin and be not easy to reach the stable problem contacted, especially the contact electrode of plane pattern, as United States Patent (USP) the 5th, 713, No. 365 described, it is easier to occur the situations such as slip, contact surface deficiency owing to for contact site, not carrying out corresponding design.So having need to provide a kind of stable blood pressure and the electrocardiosignal measuring device contacted between skin and ECG electrode can be provided.
