Description

B ultrasonic positioning marking device

Technical Field

The utility model relates to the technical field of B ultrasonic positioning marks, in particular to a B ultrasonic positioning mark device.

Background

With the increasing application of central venous catheterization to clinic, related complications caused by the central venous catheterization are more and more paid attention to medical workers, and in recent years, the central venous catheter technology is more perfected due to the introduction of the B-ultrasonic auxiliary technology.

In clinical work, patients often need intraspinal anesthesia, nerve block, deep vein puncture, central venous catheter (PICC) placement through peripheral veins and visceral fluid positioning puncture. The existing common methods are to locate and puncture according to the working experience of the clinician and the body surface marks of the patient, however, the accuracy is relatively low, and in addition, patients with difficult location are frequently encountered in clinic, so that the puncture can be successfully performed after the puncture points of the patients are accurately located under the guidance of a B ultrasonic machine.

When medical staff performs puncture point positioning and marking, marking is performed by a marker pen or by means of fingernail printing of an operator. However, medical personnel operate the B-ultrasound probe in one hand and mark in the other hand, and for some aseptic procedures or fine vascular and nerve positioning, there is a tendency to increase the risk of local infection and shift of the positioning location. In addition, if the fingernail marks are used, on one hand, unnecessary pain is caused to a patient, and on the other hand, the fingernail marks are not clearly displayed in a place with dark light, and puncture failure is easily caused.

However, the above-mentioned B-ultrasonic probe has the following disadvantages:

1. the B-ultrasonic probe positioning pen in the scheme can easily puncture skin tissues after being ejected or under the condition of loosening a spring, and particularly the B-ultrasonic probe can easily puncture skin when making deeper position marks.

2. The positioning pen used in the scheme has no sustainability, needs to replace the pen core repeatedly, and has poor cost efficiency.

From the above, we have designed a B-ultrasonic locating and marking device to solve the above problems.
