Description

Technical Field

[0001] The utility model relates to the field of human life, in particular to medical equipment, and more particularly to arteriovenous catheterization, in particular to a device for assisting in the fixation of arteriovenous catheterization. Background Art

[0002] To meet the needs of intraoperative anesthesia monitoring, many surgical patients require arterial puncture to facilitate continuous blood pressure monitoring during surgery and ensure patient safety. The radial artery and brachial artery are the most common puncture sites. After the puncture is completed, it is currently only fixed by film and tape. However, in order to meet the needs of the operation, the body position adjustment is often required, or the patient's consciousness has not fully recovered during the anesthesia recovery period and becomes agitated. These can easily cause the limb for arterial puncture to bend, the catheter to bend and block, or even the catheter to slip, resulting in the arterial waveform not being displayed normally, thereby affecting the patient's blood pressure monitoring and endangering the patient's life. The same problem also exists in peripheral venous catheterization. The common site for peripheral venous catheterization is also the upper limb. There is also a risk of the catheter bending and slipping when the patient's body position changes. There is currently no device that can be used to fix arteriovenous catheters and upper limbs during anesthesia and recovery. It is often necessary to manually adjust the limb position repeatedly to ensure the catheter is in place and unobstructed.

[0003] A patent search revealed that Publication No. CN219613987U discloses a radial artery puncture assist device that improves puncture success rates, but it cannot secure the catheter and is bulky, making it unsuitable for prolonged use during anesthesia and recovery. Publication No. CN219814337U discloses a radial artery fixation plate that can be used for thumb fixation, but is only suitable for radial artery fixation and cannot adjust wrist position. Publication No. CN115227355A discloses a multifunctional distal radial artery fixation and puncture positioning device that can be used for radial artery fixation, assisting puncture and providing compression to stop bleeding, but is also not suitable for arteriovenous fixation at the elbow. Publication No. CN215875151U discloses a radial artery fixation device that is spring-loaded for length adjustment, but cannot adjust the wrist support height and is only suitable for radial artery fixation. Publication No. CN211271228U discloses a radial artery puncture fixation device that can secure the elbow, but is bulky and unsuitable for prolonged use. Publication number CN209490006U discloses a radial artery fixator that uses airbags on both sides to adjust the fit of the fixation plate to the arm, effectively immobilizing the limb, but the wrist support height cannot be adjusted. Publication number CN2877607Y discloses a radial artery fixation puncture plate that uses an adjustable height pad to adjust the wrist position, better exposing the puncture site, elevating the puncture site, and also securing the catheter. However, the base plate lacks a silicone pad, making it unsuitable for long-term use.

[0004] It can be seen that the current related technologies are mainly used to assist radial artery puncture and improve the puncture probability. They cannot be used to fix the upper limbs and arteriovenous catheters at the same time, nor can they be used for a long time during anesthesia and recovery. In order to solve the above problems, this application proposes an arteriovenous catheter fixation device. Utility Model Content

[0005] The purpose of the present invention is to provide a device for assisting the fixation of arteriovenous catheters.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A device for assisting in the fixation of arteriovenous catheters comprises a rectangular flat plate, wherein the left side of the lower side of the flat plate is connected to the ends of two left straps, and the right side of the lower side of the flat plate is connected to the ends of two right straps, the front end of the left strap and the front end of the right strap are cooperatively provided with a connecting structure, at least one auxiliary strap is provided on the lower side of the left strap or the right strap, both ends of the auxiliary strap are connected to the lower side of the left strap or the right strap, a plurality of support pads are provided on the upper side of the flat plate, the support pads are distributed in parallel along the length direction of the flat plate, and at least one airbag is provided between the upper side of the flat plate and the support pad.

[0008] Furthermore, the connection structure is a Velcro or a snap fastener.

[0009] Furthermore, the length direction of the auxiliary strap is parallel to the length direction of the left strap or the right strap.

[0010] Furthermore, the left strap and the right strap are symmetrically arranged with the flat plate as the center.

[0011] Furthermore, the two left straps are respectively close to the front end and the rear end of the tablet, and the two right straps are respectively close to the front end and the rear end of the tablet.

[0012] Furthermore, the support pad is cylindrical.

[0013] Furthermore, the flat plate is transparent.

[0014] Furthermore, each of the airbags is connected to an inflation pipeline.

[0015] Working principle:

[0016] The utility model binds the needle body of the arteriovenous catheter by an auxiliary strap and keeps it in a relatively fixed state with the patient's arm, so that the needle body of the arteriovenous catheter will not be excessively affected even if the patient adjusts his posture or moves his arm.

[0017] Compared with the prior art, the beneficial effect of the present invention is to prevent the needle body of the patient's arteriovenous catheter from bending or slipping after the patient adjusts his posture or moves his arm. BRIEF DESCRIPTION OF THE DRAWINGS
