Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable arterial puncture boot-shaped ultrasonic probe guide sleeve. Background Art

[0002] Perioperative arterial puncture is a commonly used clinical operation technique in the perioperative period. Its main purpose is to continuously and in real time monitor the patient's arterial blood pressure, obtain arterial blood samples, and guide hemodynamic support to evaluate the patient's circulatory function and tissue perfusion. It is of great significance for adjusting the use of vasoactive drugs and evaluating blood volume status. Ultrasound guidance can help doctors observe the position, depth and morphology of the artery, as well as the positional relationship of surrounding structures in real time, making the puncture process more accurate, helping doctors avoid complications such as vascular wall rupture, hematoma, and nerve damage, and improving the success rate of puncture. However, arterial puncture is still challenging. The difficulties mainly lie in the high hand-eye coordination required, the large individual differences among patients, and the possibility of vascular wall calcification and thrombosis during catheterization, which increases the complexity and time of the puncture and catheterization operation.

[0003] Hand-eye coordination is very critical and difficult during ultrasonic puncture. Existing operating room operations rely heavily on the doctor's personal skills, so there are many uncertainties in puncture surgery. Therefore, this application proposes a disposable arterial puncture boot-shaped ultrasound probe guide set to assist in arterial puncture. Summary of the Invention

[0004] The purpose of the utility model is to solve the problems existing in the background technology and to propose a disposable arterial puncture boot-shaped ultrasound probe guide sleeve for assisting arterial puncture.

[0005] The technical solution of the utility model is as follows: a disposable arterial puncture boot-shaped ultrasound probe guide set, comprising a boot-shaped ultrasound probe body and a plastic kit for guiding the installation of the boot-shaped ultrasound probe body, wherein a sterile hydrogel film is bonded to the bottom of the plastic kit, and a puncture guide is provided at the tail end of the boot-shaped ultrasound probe body;

[0006] The plastic kit includes a mounting bracket adapted to be snap-fitted to the front end of the boot-shaped ultrasound probe body, a snap-fit ​​plate being rotatably mounted on the inner walls of both sides of the mounting bracket away from the puncture guide, guide posts being fixedly connected to both sides of the snap-fit ​​plate, and guide grooves corresponding to the positions of the guide posts being formed on both side walls of the mounting bracket;

[0007] The puncture guide comprises a C-shaped guide tube that is arranged obliquely, and an open channel is opened on one side of the C-shaped guide tube.

[0008] Optionally, both ends of the clamping plate are fixedly connected to a rotating shaft, and one end of the rotating shaft is rotatably connected to the inner wall of the mounting frame.

[0009] Optionally, the outer ring of the rotating shaft is sleeved with a spring, the guide groove is an arc groove, and one end of the guide column located in the guide groove is an arc surface.

[0010] Optionally, a pressing block is fixedly connected to the top middle portion of the clamping plate.

[0011] Optionally, a puncture cavity is provided on the inner wall of the C-shaped guide tube.

[0012] Optionally, the opening channel is connected to the puncture cavity, and a plurality of through windows are provided on the C-shaped guide tube.

[0013] Optionally, the C-shaped guide tube is arranged to be inclined at 30° to the bottom of the boot-shaped ultrasound probe body.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This utility model improves the problem of difficult hand-eye coordination during ultrasound-guided arterial puncture. By covering the ultrasound probe with a plastic kit, the artery is directly identified in the ultrasound image and placed in the center of the field of view. The sterile hydrogel film replaces the traditional conductive paste to help fix the probe position and facilitate ultrasound conduction. There is no need to adjust the puncture angle during puncture. The setting of the puncture guide assists in the puncture angle and puncture site, greatly controlling the puncture deviation caused by poor hand-eye coordination.

[0016] The utility model also clamps the main body of the boot-shaped ultrasonic probe into the interior of the plastic kit by pressing the pressing block and the clamping plate, thereby facilitating the stable installation of the main body of the boot-shaped ultrasonic probe and the plastic kit.

[0017] In summary, the utility model has a novel and compact structure, assists in arterial puncture, reduces the difficulty of puncture, and improves the accuracy and efficiency of puncture. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figures 1 to 4As shown, the disposable arterial puncture boot-shaped ultrasound probe guide sleeve proposed by the present invention includes a boot-shaped ultrasound probe body 1 and a plastic kit 2 for guiding the installation of the boot-shaped ultrasound probe body 1. The plastic kit 2 is used to install the boot-shaped ultrasound probe body 1. A sterile hydrogel film 3 is bonded to the bottom of the plastic kit 2. A puncture guide 4 is provided at the tail end of the boot-shaped ultrasound probe body 1. The puncture guide 4 is used to guide the puncture needle for puncture.

[0034] The plastic kit 2 includes a mounting bracket 21 adapted to be snap-fitted to the front end of the boot-shaped ultrasound probe body 1. A mounting plate 22 is rotatably mounted on the inner walls of both sides of the mounting bracket 21 away from the puncture guide 4. A pressing block 23 is fixedly connected to the top middle part of the mounting plate 22. A rotating shaft 24 is fixedly connected to both ends of the mounting plate 22. One end of the rotating shaft 24 is rotatably connected to the inner wall of the mounting bracket 21. A spring 25 is installed on the outer ring of the rotating shaft 24. By setting the pressing block 23, one end of the mounting plate 22 is fixedly connected to the inner wall of the mounting bracket 21. By pressing from the side, the clamping plate 22 rotates along the rotating shaft 24, and the other end is tilted, thereby achieving the purpose of canceling the clamping limit of the boot-shaped ultrasound probe body 1; guide columns 26 are fixedly connected to both sides of the clamping plate 22, and guide grooves 27 corresponding to the positions of the guide columns 26 are provided on both side walls of the mounting frame 21. The guide groove 27 is an arc groove, and the end of the guide column 26 located in the guide groove 27 is an arc surface. By pressing the pressing block 23, the guide column 26 rotates along the arc surface of the guide groove 27.

[0035] like Figure 2 and Figure 3 As shown, the puncture guide 4 includes a C-type guide tube 41 that is arranged at an angle. The C-type guide tube 41 is fixedly connected to the side of the plastic kit 2 away from the clamping plate 22. The C-type guide tube 41 is inclined at 30° to the bottom of the boot-shaped ultrasound probe body 1. The inner wall of the C-type guide tube 41 is provided with a puncture cavity passing through it. An opening channel 42 is provided on one side of the C-type guide tube 41. The opening channel 42 is connected to the puncture cavity. A plurality of through windows 43 are provided on the C-type guide tube 41.

[0036] In this embodiment, the probe end of the boot-shaped ultrasound probe body 1 is first installed with the plastic kit 2, and the pressing block 23 is first pressed downward to rotate the clamping plate 22 along the rotating shafts 24 connected on both sides, so that the other end of the clamping plate 22 is rotated along the guide column 26 and the guide groove 27 to open the other end of the clamping plate 22, and press the upper part of the boot-shaped ultrasound probe corresponding to the mounting bracket 21 to achieve the probe end of the boot-shaped ultrasound probe body 1 being fitted with the sterile hydrogel membrane 3, and the pressing block 23 is released, and the spring 25 rotates and rebounds to achieve the clamping of the other end of the clamping plate 22 with the positioning protrusion mark of the boot-shaped ultrasound probe body 1, so as to achieve the boot-shaped ultrasound. The probe body 1 and the plastic kit 2 are installed by tearing off the release film on the sterile hydrogel film 3 to replace the traditional conductive paste, which can avoid the fluidity of the conductive paste and the sliding displacement of the probe. During puncture, the arterial imaging is placed in the center of the screen, and then the puncture needle is punctured through the puncture cavity channel of the C-shaped guide tube 41. When the puncture needle enters the blood vessel or blood returns at the tail end of the arterial puncture needle under ultrasound, the plastic kit 2 and the boot-shaped ultrasound probe body 1 are withdrawn as a whole, where the opening channel 42 begins, so that the plastic kit 2 and the boot-shaped ultrasound probe body 1 can be withdrawn without touching, and other operation steps such as catheterization are performed in combination with the puncture position of the puncture needle.

[0037] The above specific embodiment is only an optional embodiment of the present invention.
