Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a transcranial Doppler microembolism monitoring head frame. Background Art

[0002] Transcranial Doppler (TCD) detection of microemboli in the cerebral circulation is an emerging diagnostic technique for ischemic cerebrovascular disease. It is increasingly being used in neurological clinical practice, playing a particularly important role before and after interventional treatment for ischemic cerebrovascular disease. However, during this testing process, the microembolic monitoring heads provided by major TCD instrument manufacturers require manual installation and are extremely difficult to secure. Therefore, improving the ease of installation of these heads is crucial.

[0003] Currently, in the existing technology, the installation of the microembolism monitoring head frame relies solely on manual installation by medical personnel. First, the examinee needs to be informed of the time required for the examination and the possible feeling of a tight headband during the examination. After the examinee cooperates for a long time, the five tightening switches usually equipped on the head frame are tightened. Then, the medical personnel first performs a routine transcranial Doppler examination and then holds the probe by hand to perform microembolism detection for at least half an hour. During the process, after completing the routine transcranial Doppler examination, a marking pen can be used to mark the detection point to narrow the detection range, thereby shortening the detection time.

[0004] Currently, in the existing technology, only subjects whose blood flow signal spectrum can be detected during routine transcranial Doppler examinations are suitable for microemboli monitoring. Therefore, the subject's head needs to be tightly clamped for a long time for multiple monitoring, which causes great discomfort to the patient and is extremely time-consuming. In addition, due to the high precision required for the detection, it is necessary to mark the detection points with a marker pen after the routine transcranial Doppler examination in order to narrow the detection range. This operation is also extremely time-consuming if it relies solely on manual operation. Moreover, any slight shaking of the patient will cause the fixation to fail and have to be restarted, which is extremely inconvenient and inefficient. In addition, the five tightening switches usually equipped on the head frame need to be manually tightened by medical staff, which is very laborious and difficult to ensure accuracy. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose a transcranial Doppler microembolism monitoring head frame, which solves the problem in the existing technology that manual installation is time-consuming, labor-intensive, inefficient, and prone to errors, resulting in the need for repeated testing and adjustment, aggravating the patient's discomfort and causing low detection efficiency and accuracy by providing a transcranial Doppler microembolism monitoring head frame with automatic fixing and locking functions, flexible fixing functions, and real-time follow-up marking functions.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] In the above description of the present invention, it should be noted that the terms "one side," "the other side," and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0031] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0032] like Figure 1-7 As shown, an embodiment of the present invention provides: a transcranial Doppler microemboli monitoring head frame, including an elastic initial positioning headband 1, the elastic initial positioning headband includes an elastic headband 2 and a belt-shaped position signal transceiver 3.

[0033] The elastic initial positioning headband is covered with a self-rotating and self-locking monitoring head frame 4. The self-rotating and self-locking monitoring head frame includes an inflatable self-locking fixed airbag 5, a ring-shaped electromagnetic slide 6 fixedly set on the outer surface of the inflatable self-locking fixed airbag, and an electromagnetic slider base 7 that cooperates with the electromagnetic slide. When worn, the inflatable self-locking fixed airbag is fixed between the inner side of the self-rotating and self-locking monitoring head frame and the outer side of the elastic headband. The inner surface of the inflatable self-locking fixed airbag is dotted with anti-slip wave dots 8. The purpose is to enable the inflatable self-locking fixed airbag to drive the self-rotating and self-locking monitoring head frame to be firmly fixed to the outer side of the elastic initial positioning headband to prevent it from falling off. In addition, the inflatable self-locking fixed airbag and the inflatable fixed ring sleeve are both connected to the external inflator through a micro air tube.

[0034] A probe holder 9 is fixed to the side of the self-rotating, self-locking monitoring head frame. An inflatable fixing ring 10, used to clamp and release the probe, is fixed inside the probe holder. The probe holder is connected to the electromagnetic slider base via an electric rocker arm 11 and an electric telescopic rod 12. A position signal transmitter 13 is fixed to the probe holder for real-time transmission of its position relative to the strip position signal transceiver. Because the strip position signal transceiver is extremely securely fixed to the elastic headband of the patient's head, it can be used as a fixed reference system. Even slight shaking will not cause it to shift, so the coordinate position data derived from it as a reference system can be used as an accurate reference. The probe holder locks the initial detection position of a conventional transcranial Doppler examination probe. In particular, after the position signal transmitter transmits, the strip position signal transceiver receives and confirms the signal and feeds it back to the central controller. After replacing the microembolic monitoring probe, the probe can still quickly and accurately return to its original position in the new coordinate system, avoiding the possibility of probe position deviation during replacement.

[0035] A central controller 14 is mounted on the exterior of the self-rotating, self-locking monitoring head frame. This controller is wirelessly connected to the elastic initial positioning headband, the self-rotating, self-locking monitoring head frame, the probe holder, and the position signal transmitter. Marking paint sprayers 15 are evenly distributed and fixed inside the probe holder. Surrounding the marking paint sprayers are dedicated identification locators 16, capable of identifying the paint sprayed by the marking paint sprayers. These locators operate by detecting the paint through optical reflection.

[0036] When implementing this embodiment, the elastic initial positioning headband is first firmly worn on the patient's head. Since different patients have different heads, several different models of elastic initial positioning headbands are set up. Due to the elastic properties of the silicone, initial positioning headbands of similar models can be firmly fixed on the patient's head without displacement. After wearing the initial positioning headband, the self-rotating and self-locking monitoring head frame is fixedly worn on the outside of the initial positioning headband. The inflatable self-locking fixed airbag is inflated so that it can be firmly clamped and fixed on the outside of the initial positioning headband. Then, a conventional transcranial Doppler examination probe is first placed in the probe holder, and then the inflatable fixed ring is inflated to clamp the probe. Then, the central controller controls the electromagnetic slide rail, the electric telescopic rod and the electric rocker arm to work together to make the probe find the target detection site. When the detected image meets the requirements, the medical staff records it on the central controller. At this time, the position data of the point is obtained relative to the coordinate system established by the initial positioning headband, and then the marking paint sprayer is controlled to spray detectable visual paint at this position. Then the probe is replaced with a microemboli monitoring probe. When the central controller is used to control the device so that the position signal transmitted back in real time by the position signal transmitter on the probe holder is the same as the position signal of the site determined by the previous preliminary detection, and at the same time, the identification locator can identify and capture the spraying point, it proves that the device has returned to the original marking position. The purpose of spraying recognition is to be able to detect the movement of the device and make timely adjustments even if an unexpected movement occurs when the position information and mark recognition are not satisfied. When both double-guaranteed recognitions are met, accurate detection can be started. The entire observation process does not require hand-held equipment, and only occasional adjustment of the central controller is required.

[0037] This embodiment provides a transcranial Doppler microembolism monitoring head frame with automatic fixing, locking and tightening functions, flexible fixing function and real-time follow-up marking function. The initial positioning headband of silicone material is conducive to flexible fixation. The central controller controls the inflator to automatically inflate and deflate the self-locking fixed airbag, which is conducive to the automatic fixing, locking and tightening function. The real-time synchronous marking through position signal induction transmission combined with electromagnetic slide rail sliding positioning is conducive to the follow-up marking function and prevention of head movement interference, thereby realizing automatic installation and fixation of the headgear and greatly improving detection efficiency and accuracy.

[0038] In this embodiment, the elastic initial positioning headband is made of silicone, which can maintain friction and achieve flexible wearing to reduce patient discomfort.

[0039] In this embodiment, the surfaces of the self-rotating and self-locking monitoring head frame, the probe holder and the position signal transmitter are sprayed with a waterproof insulating coating, which helps to prevent the electrical components from being corroded and prevent leakage from affecting the detection accuracy.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
