Embodiment 1

[0029] refer to Figure 1-Figure 4 As shown in the figure, an ultrasound-guided in-plane multi-angle puncture injection device is shown, including an in-plane multi-angle adjustment device 200, a puncture needle 300, a negative pressure device 400 and a drug delivery device 500. In this embodiment The puncture needle 300 is a medical injection fine needle, which is suitable for patients who do not need to indwell a drug injection tube.

[0030] The in-plane multi-angle adjustment device 200 is clamped on one side of the ultrasonic probe 100 when the medical staff performs in-plane needle insertion. The in-plane multi-angle adjustment device 200 includes a sector-shaped adjustment block 210 with a central angle of 90°. One side of 210 is provided with a clamping arm 220 for clamping on one side of the ultrasonic probe 100 , and the fan-shaped adjustment block can be firmly clamped on one side of the ultrasonic probe 100 through the clamping arm 220 . In this embodiment, the in...

Embodiment 2

[0040] combine Figure 5 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1. The difference is that the puncture needle in this embodiment is a thick-diameter needle 300a with an inner core 300b, and the thick-diameter needle 300a is a medical steel needle of 18-20G , its inner diameter is slightly thicker than the inner diameter of medical injection fine needles, and can be placed into thin drug injection tubes. The tee joint 310 is also provided with a fourth joint end 313 for inserting the inner core 300b of the thick-diameter needle 300a. The fourth joint end 313 is provided with a one-way stop elastic flap 313a. This embodiment is suitable for patients who need to indwell the drug injection tube in the later stage.

Abstract

The invention discloses an ultrasonic guided in-plane multi-angle puncture medicine injection device, which comprises an in-plane multi-angle adjusting device fixedly connected on one side of an ultrasonic probe when medical personnel carry out in-plane needle insertion; a puncture needle used for puncture by medical personnel; a negative pressure device for detecting whether the puncture needle is punctured into a blood vessel; an administration device for administration after the puncture needle is punctured to a desired puncture position. By adopting the structure, medical personnel can quickly find target positioning in the plane under ultrasonic guidance, the puncture needle can be ensured to always walk in the plane, in addition, all puncture and medicine injection work can be completed only by one doctor, so that the working efficiency of medical personnel is improved, the blocking time under ultrasound is shortened, and the complications of patients are reduced. Furthermore, the device can also achieve the tube placing and medicine injection functions according to actual requirements.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an in-plane multi-angle puncture drug injection device guided by ultrasound. Background technique [0002] The development of visualization technology provides opportunities for rapid development of multimodal analgesia in the perioperative period. Ultrasound guidance can enable anesthesiologists to accurately and easily position the puncture needle at the nerve or fascial plane to be blocked. At present, there are two types of needle insertion approaches for nerve or plane block under ultrasound guidance: one is out-of-plane needle insertion, and the other is in-plane needle insertion. Both approaches have advantages and disadvantages. Out-of-plane needle insertion is quick and easy, and is suitable for experienced anesthesiologists. However, during the puncture process, the movement of the puncture needle cannot be observed in real time, and important structures such a...
