Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a blood vessel puncture guidance auxiliary device and a blood vessel puncture guidance method. Background Art

[0002] Vascular puncture technology, especially arterial and venous puncture and catheterization, is a common technology for the treatment of critically ill patients. Traditional vascular puncture technology relies entirely on anatomical positioning or finger touch, which is a blind operation, potentially increasing the risk of complications such as bleeding, hematoma, pseudoaneurysm and arteriovenous fistula, affecting the patient's life safety.

[0003] Ultrasonic diagnostic equipment can clearly display the deep tissue structure of the human body and accurately locate the target. It can also observe the dynamic changes of the target in real time, providing the possibility for vascular imaging positioning and puncture guidance.

[0004] However, since the ultrasound probe and the image on the display are physically separated, it is difficult for the vascular puncture operator to determine the relative physical positions of the needle, blood vessel, and ultrasound probe. The success rate of vascular puncture needs to be improved, which limits the role of ultrasound technology in the field of vascular puncture. This patented technology aims to solve the problem of how to use ultrasound equipment to locate blood vessels and guide vascular puncture. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies of the prior art, the present invention provides a vascular puncture guidance auxiliary device and a vascular puncture guidance method, which solve the problem that the success rate of vascular puncture guided by ultrasonic imaging equipment is not high.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A blood vessel puncture guidance auxiliary device, the guidance auxiliary device comprising: an ultrasonic diagnostic instrument and a marking module;

[0010] The ultrasonic diagnostic instrument comprises: a device host and an ultrasonic probe; a needle insertion mark is arranged on the side wall of the ultrasonic probe housing;

[0011] The device host includes: a display and an input control module;

[0012] The marking module displays a first marking auxiliary line, a second marking auxiliary line and a third marking auxiliary line on the display; the first marking auxiliary line corresponds to the position of the needle insertion mark;

[0013] The positions of the second marking auxiliary line and the third marking auxiliary line on the display can be freely adjusted through the input control module.

[0014] Preferably, the first marking auxiliary line, the second marking auxiliary line and the third marking auxiliary line are all arranged vertically, and the input control module controls the second marking auxiliary line and the third marking auxiliary line to move horizontally.

[0015] Preferably, the first marking auxiliary line bisects the image of the target blood vessel, and the second marking auxiliary line and the third marking auxiliary line are tangent to the vessel walls on both sides of the target blood vessel respectively.

[0016] Preferably, the method comprises the following steps in sequence:

[0017] S1, target vessel imaging

[0018] The ultrasonic diagnostic apparatus is powered on, and the target blood vessel is detected by holding the ultrasonic probe. The detected images of the target blood vessel and surrounding tissues are displayed on the display of the ultrasonic diagnostic apparatus. The position of the ultrasonic probe is adjusted so that the image of the target blood vessel is bisected by the first marking auxiliary line, and the relative position of the ultrasonic probe and the skin is fixed;

[0019] S2, target vessel mapping

[0020] The positions of the second marking auxiliary line and the third marking auxiliary line are respectively adjusted through the input control module so that the two are tangent to the walls of both sides of the target blood vessel respectively;

[0021] S3. Vascular puncture

[0022] The needle insertion position and direction are determined by the needle insertion mark on the ultrasound probe. During the needle insertion process, the needle tip is always kept between the second marking auxiliary line and the third marking auxiliary line to limit the needle insertion range until the needle tip enters the target blood vessel cavity.

[0023] Preferably, in S2, the positions of the second and third marking auxiliary lines are symmetrically adjusted with the first marking auxiliary line as the central axis through the input control module, so that the two are tangent to the vessel walls on both sides of the target blood vessel respectively.

[0024] (III) Beneficial effects

At this time, the needle insertion mark is just above the target blood vessel, providing an accurate reference for the needle insertion position; by adjusting the positions of the second marking auxiliary line and the third marking auxiliary line, the horizontal diameter range of the target blood vessel is traced, providing an auxiliary reference for the needle insertion angle and the adjustable direction, thereby ensuring that the vascular puncture has a very high success rate, effectively avoiding the occurrence of complications, and ensuring the patient's life safety.

[0032] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0033] In the embodiment of the present invention, with the assistance of the first marking auxiliary line corresponding to the needle insertion mark position on the ultrasound probe, the operator is helped to clarify the physical spatial relationship between the target blood vessel, the needle insertion mark and the ultrasound image; the position of the ultrasound probe is adjusted so that the image of the target blood vessel is bisected by the first marking auxiliary line.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Embodiment 1:

[0036] like Figure 1 , Figure 2 As shown, the present invention provides a blood vessel puncture guidance auxiliary device, the guidance auxiliary device comprising: an ultrasonic diagnostic instrument and a marking module;

[0037] The ultrasonic diagnostic instrument comprises: a device host and an ultrasonic probe 1; a needle insertion mark 11 is provided on the side wall of the shell of the ultrasonic probe 1;

[0038] The device host includes: a display and an input control module;

[0039] The marking module displays a first marking auxiliary line 10, a second marking auxiliary line 20 and a third marking auxiliary line 30 on the display; the first marking auxiliary line 10 corresponds to the position of the needle insertion mark 11, and during the movement of the ultrasonic probe 1, the image in the display moves with the ultrasonic probe 1, and the position of the first marking auxiliary line 10 on the display is fixed. For example, if the needle insertion mark 11 is located at the central axis position of the ultrasonic probe 1, then the first marking auxiliary line 10 is fixed at the central axis position of the display, corresponding to the position of the needle insertion mark 11;

[0040] The positions of the second marking auxiliary line 20 and the third marking auxiliary line 30 on the display can be freely adjusted through the input control module.

[0041] like Figure 1 As shown, the first marking auxiliary line 10, the second marking auxiliary line 20 and the third marking auxiliary line 30 are all arranged vertically, and the input control module controls the second marking auxiliary line 20 and the third marking auxiliary line 30 to move horizontally.

[0042] like Figure 1As shown, during the process of guiding blood vessel puncture, the guidance auxiliary device adjusts the position of the ultrasound probe 1 so that the image of the target blood vessel 40 is bisected by the first marking auxiliary line 10, and the positions of the second marking auxiliary line 20 and the third marking auxiliary line 30 are adjusted through the input control module so that the two are tangent to the walls of both sides of the target blood vessel 40 respectively.

[0043] The needle insertion mark 11 provides a reference for the needle insertion position. During the needle insertion process, the needle 50 is always ensured to be located between the second mark auxiliary line 20 and the third mark auxiliary line 30, which can ensure that the vascular puncture has a very high success rate, effectively avoid the occurrence of complications, and ensure the patient's life safety.

[0044] Embodiment 2:

[0045] The present invention provides a blood vessel puncture guidance method, which comprises the following steps in sequence:

[0046] S1, target vessel imaging

[0047] The ultrasonic diagnostic apparatus is powered on, and the target blood vessel 40 is detected by holding the ultrasonic probe 1. The detected image of the target blood vessel 40 and the surrounding tissue is displayed on the display of the ultrasonic diagnostic apparatus. The position of the ultrasonic probe 1 is adjusted so that the image of the target blood vessel 40 is bisected by the first marking auxiliary line 10, and the relative position of the ultrasonic probe 1 and the skin is fixed;

[0048] S2, target vessel mapping

[0049] The positions of the second marking auxiliary line 20 and the third marking auxiliary line 30 are respectively adjusted through the input control module so that the two are tangent to the walls of both sides of the target blood vessel 40 respectively;

[0050] S3. Vascular puncture

[0051] The needle insertion position and direction are determined by the needle insertion mark 11 on the ultrasound probe 1. During the needle insertion process, the needle 50 is always kept between the second marking auxiliary line 20 and the third marking auxiliary line 30 to limit the needle insertion range until the needle 50 enters the target blood vessel 40 cavity.

[0052] With the assistance of the first marking auxiliary line 10 corresponding to the position of the needle insertion mark 11, the operator is helped to clearly understand the physical spatial relationship between the target blood vessel 40, the needle insertion mark 11 and the ultrasound image; the position of the ultrasound probe 1 is adjusted so that the image of the target blood vessel 40 is bisected by the first marking auxiliary line 10. At this time, the needle insertion mark 11 is located just above the target blood vessel 40, providing an accurate reference for the needle insertion position; by adjusting the positions of the second marking auxiliary line 20 and the third marking auxiliary line 30, the horizontal diameter range of the target blood vessel 40 is traced, providing an auxiliary reference for the needle insertion angle and the adjustable direction, thereby ensuring that the vascular puncture has a very high success rate, effectively avoiding the occurrence of complications, and protecting the patient's life safety.

[0053] In S3, the first marking auxiliary line 10 can be hidden by the input control module before the needle is inserted, so as to prevent the first marking auxiliary line 10 from blocking the operator's sight and affecting the operator's observation of the position of the needle 50 during the needle insertion process.

[0054] Embodiment 3:

[0055] In S2 of Example 2, the input control module is used to symmetrically adjust the positions of the second and third marking auxiliary lines 20 and 30 with the first marking auxiliary line 10 as the central axis, so that they are tangent to the walls of the target blood vessel 40 on both sides.

[0056] Embodiment 4:

[0057] In S3 of Example 2, the needle insertion position and direction are determined by the needle insertion mark 11 on the ultrasound probe 1. During the needle insertion process, the needle 50 is kept inserted along the direction of the first mark auxiliary line 10 until the needle 50 enters the lumen of the target blood vessel 40.

[0058] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0059] In the embodiment of the present invention, with the assistance of the first marking auxiliary line corresponding to the needle insertion mark position on the ultrasound probe, the operator is helped to clarify the physical spatial relationship between the target blood vessel, the needle insertion mark and the ultrasound image; the position of the ultrasound probe is adjusted so that the image of the target blood vessel is bisected by the first marking auxiliary line. At this time, the needle insertion mark is just above the target blood vessel, providing an accurate reference for the needle insertion position; by adjusting the positions of the second marking auxiliary line and the third marking auxiliary line, the horizontal diameter range of the target blood vessel is traced, providing an auxiliary reference for the needle insertion angle and the adjustable direction, thereby ensuring that the vascular puncture has a very high success rate, effectively avoiding the occurrence of complications, and ensuring the patient's life safety.
