Description

Technical Field

[0001] The utility model relates to the technical field of B-ultrasound positioning marking, in particular to a B-ultrasound positioning marking device. Background Art

[0002] As central venous catheterization is increasingly used in clinical practice, the related complications caused by it have received more and more attention from medical workers. In recent years, the introduction of B-ultrasound-assisted technology has made central venous catheter technology more perfect.

[0003] In clinical work, patients are often required to undergo spinal anesthesia, nerve block, deep vein puncture, peripherally inserted central catheter (PICC) and puncture for fluid accumulation in organs. Currently, the commonly used method is to locate the puncture based on the clinician's work experience and the patient's body surface landmarks. However, the accuracy rate is relatively low. In addition, we often encounter patients with difficult positioning in clinical practice. Therefore, it is necessary to accurately locate the patient's puncture point under the guidance of a B-ultrasound machine before the puncture can be successful.

[0004] In clinical practice, medical staff usually use a marker pen to mark the puncture point, or rely on the operator's fingernail prints to mark. However, when medical staff operate the B-ultrasound probe with one hand and mark with the other hand, the risk of local infection and displacement of the positioning position will inevitably increase for some sterile operations or delicate blood vessel and nerve positioning; some existing positioning marking devices are mostly unable to adjust the angle, and there is a deviation between the marking position and the positioning position, which can easily cause puncture failure and cause problems.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0021] For ease of description, spatial relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature shown in a figure relative to another element or feature. It should be understood that the spatial terms are intended to include different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figure is inverted, elements described as being "below" other elements or features will be positioned "above" the other elements or features. Thus, the exemplary term "below" may include both upper and lower orientations.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation of the present invention is described in detail below in conjunction with specific embodiments: Figure 1-Figure 6 The utility model shown is realized by the following technical scheme: a B-ultrasound positioning marking device, including a B-ultrasound probe 6, a slider 8, a marker 4 and a slide tube, characterized in that: the B-ultrasound probe 6 is connected to an acoustic lens 10, the B-ultrasound probe 6 is fixedly connected to a slide rail 14, the slide rail 14 is slidably connected to the slider 8, the slider 8 is fixedly connected to a first bracket 7, one end of a telescopic rod 1 is hinged on the first bracket 7, and the other end of the telescopic rod 1 is hinged to a first slide tube 3.
