Description

Craniocerebral ultrasonic auxiliary device for bedside dynamic monitoring technology

Technical Field

The application relates to a craniocerebral ultrasonic auxiliary device for bedside dynamic monitoring technology, belonging to the technical field of medical auxiliary instruments.

Background

The current clinical application of ultrasonic craniocerebral examination mainly comprises the following steps: transcranial Doppler ultrasound (TCD), transcranial color-code real time ultrasound (TCCS), transcranial contrast-enhanced ultrasound (t-CEUS).

Among them, TCD is the most widely used ultrasonic craniocerebral examination technique with the longest history of development. As the adult patient is shielded by the skull, the sound waves are difficult to penetrate the skull for imaging. Therefore, when TCD examination is performed, an operator needs to hold the probe and repeatedly explore the weak point of the winged point skull of a patient so as to obtain intracranial blood flow signals. Because the exploration window is narrow and easy to displace and lose blood flow signals, a TCD auxiliary support is born to help an operator to carry out examination (as shown in figure 1), and the conventional auxiliary support comprises a head fixing component and a probe fixing component, wherein the head fixing component is formed by sleeving two crossed binding bands on the skull, and a probe A is fixed on the probe fixing component.

The TCCS technology combines a color Doppler mode on the basis of a TCD two-dimensional gray scale image, can more clearly obtain distribution and running information of intracranial blood vessels, is convenient for an inspector to adjust the angle between a sound beam and the blood vessels, and obtains more accurate Doppler blood flow spectrum. Meanwhile, the method can also observe the structural abnormality of the cranium, dynamically evaluate the regulation function of the cerebral blood flow and evaluate the brain tissue perfusion (namely t-CEUS technology) through a contrast mode, and is gradually applied to various severe neurological patients such as craniocerebral trauma, cerebral apoplexy and the like in recent years. During examination, an operator holds the high-frequency ultrasonic probe and also selects a temporal point skull weak part or a skull defect part for exploration. Like the traditional TCD examination, the TCCS examination window through the temporal window is small, and the hand-held probe is easily displaced to lose images, so the stability requirement on the relative position of the probe and the skull is high. But at present, an auxiliary device for the examination is still lacking clinically, and the existing TCD auxiliary bracket cannot be used universally and is not suitable for being worn and fixed by critically ill patients in a supine position.

To sum up, the existing TCD auxiliary support has the following disadvantages: 1) The probe is only suitable for a specific TCD inspection probe and has no universality with a TCCS probe; 2) The wearing difficulty of the critical patient in the supine position examination is high, the comfort level is low, and local pressure sores are easy to generate; 3) After a part of severe neurologic patients are subjected to bone flap removing and decompression, the skull has defects of different degrees, and the auxiliary device cannot be worn.

SUMMERY OF THE UTILITY MODEL

It is an object of the present application to provide an accessory stent with probe versatility and suitable for transcranial ultrasound examinations (including TCCS and t-CEUS) of bed-ridden critically ill patients.

In order to achieve the above purpose, the technical scheme of the application is to provide a craniocerebral ultrasonic auxiliary device for bedside dynamic monitoring technology, which is characterized by comprising a bracket base, a head fixing component and a probe fixing component; a central pit is formed in the center of the support base, and a first fixing belt and a second fixing belt are arranged on the front side of the central pit and the support base; the head fixing component is fixedly arranged at the rear side of the central recess; the probe fixing component is fixedly arranged on the support base and comprises a vertical telescopic arm, the top end of the vertical telescopic arm is hinged with a cross arm, and the cross arm is connected with a fixing claw for grabbing the ultrasonic probe through a spherical hinge. The support base comprises two layers, wherein a hard plate layer is arranged at the lower layer of the support base, and a soft gel layer is arranged at the upper layer of the support base. The soft gel layer and the central depression enhance the fitting degree and comfort of the back pillow part and prevent pressure sores. The probe fixing component can be adjusted universally and is suitable for various ultrasonic probes.

Preferably, the first fixing band is a forehead head fixing band, and the second fixing band is a neck fixing band.

Preferably, the head fixing component comprises a fixing arm, the bottom end of the fixing arm is fixedly arranged on the support base, the fixing arm main body is bent towards the front side to form a semi-arch shape fitting with the shape of a skull, a fixing platform for fixing the fixing band I is arranged at the top end of the fixing arm, the fixing band I is obliquely upwards from the neck root of the patient from the neck of the patient, and the fixing band I is fixed on the fixing platform after passing through a zygomatic arch to a forehead brow arch (the temporal window examination area cannot be shielded).

Preferably, the fixed arm is sleeved with a skull fixing clamp, the skull fixing clamp comprises two elastic clamping arms extending towards two sides, and the tail ends of the elastic clamping arms are provided with suckers positioned at the mastoid part of the skull of the patient. The mastoid part has prominent bony mark, is easy to fix, is generally not influenced by the bone flap removing operation, and does not shield the ultrasonic exploration area.

This application advantage lies in:

1) The probe is suitable for TCCS probes and fills up the gap of clinical application;

2) The device is suitable for the supine position examination of critically ill patients, is easy to wear, has good comfort level and is not easy to generate pressure sores.

3) After a part of severe neurological patients are subjected to bone flap removing and decompression, the skull has defects of different degrees and generates depression or bulge; therefore, the probe fixing component is modified into universal adjustment and matched with the delay block, so that the fitting degree can be increased, and the probe fixing component is suitable for being worn and used under different clinical scenes.
