Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to a wrist fixation strap for radial artery puncture and catheterization for pressure measurement. Background Technology

[0002] During surgery, real-time blood pressure monitoring typically involves radial artery puncture and catheterization connected to a transducer. The arterial waveform and values ​​provide anesthesiologists with real-time information on the patient's circulation, offering evidence for decision-making. However, in clinical practice, awake patients may experience difficulty immobilizing their bodies due to anxiety, increasing the failure rate of punctures. When patients are under anesthesia, their wrists cannot maintain a relatively hyperextended position. This is often due to the need for draping the upper limb, the surgeon's presence, and the fact that the arm on the puncture / catheter placement side cannot be placed on a hand rest during and after the procedure. This suboptimal hand position frequently leads to the radial artery catheter adhering to the artery wall, preventing proper blood flow counterflow and resulting in unsatisfactory arterial waveforms. This distorts the data, requiring anesthesiologists to repeatedly adjust the patient's hand position to confirm normal arterial waveforms, thus taking up time that could be spent on other patient needs, potentially delaying emergency care, causing inconvenience for anesthesiologists, and threatening medical safety. At the same time, the tubing connecting the arterial transducer to the arterial puncture catheter also needs to be secured to prevent the catheter from dislodging and causing bleeding. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a wrist fixation strap for radial artery puncture and catheterization for pressure measurement, so as to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A wrist fixation strap for radial artery puncture and catheterization for pressure measurement is provided, comprising a strap body having a length extending along the arm direction, with the front end and rear end of the strap body being the finger and wrist respectively, and the strap body having a first transverse strap, a diagonal strap and a second transverse strap arranged sequentially on both sides along its length direction, and a support pad located between the diagonal strap and the second transverse strap, the support pad being located at the wrist.

[0006] As described in the radial artery puncture and catheterization pressure measurement wrist fixation bandage, the finger portion of the band body has a finger sleeve, the finger sleeve has an open end facing the rear, the finger sleeve is located on the upper surface of the band body, and the support pad is located on the lower surface of the band body.

[0007] As described in the radial artery puncture and catheterization pressure measurement wrist fixation bandage, the support pad is a cylindrical pad, and the cylindrical pad is located laterally at the wrist.

[0008] As described in the radial artery puncture and catheterization for pressure measurement wrist fixation bandage, wherein the oblique bandage extends obliquely forward from the band body.

[0009] As described above, the wrist fixation bandage for radial artery puncture and catheterization for pressure measurement is provided, wherein the angle between the oblique bandage and the transverse bandage is 20°-30°.

[0010] The beneficial effects of this utility model's technical solution are:

[0011] The structure is reasonably designed to allow patients in a conscious or anesthetized state to maintain a relatively hyperextended and stable wrist joint, ensuring smooth puncture and real-time monitoring of waveforms and reliable data after catheter placement. It can also fix the arterial transducer tubing to prevent dislodgement and bleeding. Attached Figure Description

[0018] The use of the terms "comprising," "having," and "including," and variations thereof, herein means to include the items listed herein, their equivalents, and additional items. While reference may be made in the description of the drawings to directions such as above, below, upward, downward, backward, bottom, top, front, rear, etc., for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the invention in any form. Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0019] See Figure 1 , Figure 2 As shown in the preferred embodiment, the radial artery puncture catheterization and pressure measurement wrist fixation strap of this utility model includes a strap body 1, which has a length extending along the arm direction. The front end and rear end of the strap body 1 are respectively the finger part 2 and the wrist part 3. The strap body 1 is provided with a first transverse strap 4, a diagonal strap 5 and a second transverse strap 6 on both sides along the length direction. A support pad 7 is provided on the strap body 1 between the diagonal strap 5 and the second transverse strap 6. The support pad 7 is located on the wrist part 3.

[0020] In this embodiment, the first horizontal strap 4, the diagonal strap 5, and the second horizontal strap 6 are located on the left and right sides of the strap body 1 as shown in the figure. The first horizontal strap 4 and the second horizontal strap 6 are of equal length, while the diagonal strap 5 is slightly longer.

[0021] Furthermore, the finger portion of the band body 1 has a finger sleeve 8, which has an open end facing rearward to accommodate multiple fingers. The finger sleeve 8 is located on the upper surface of the band body 1, and the support pad 7 is located on the lower surface of the band body 1. This finger sleeve enhances finger protection; when the patient's arm is wrapped in a surgical drape and close to the body, the fingers, protected by the finger sleeve, can avoid injury caused by compression from surgical positioning frames or similar devices.

[0022] Specifically, support pad 7 is a cylindrical pad positioned horizontally at the wrist. It's easy to understand that the length of the cylindrical pad can be approximately the same width as the wrist, or slightly wider. The cylindrical pad elevates the wrist, allowing it to be in a relatively hyperextended state even when hanging naturally. Additionally, when the patient's arm is wrapped in surgical drapes and close to the body during surgery, the cylindrical pad's support also helps maintain a relatively hyperextended wrist.

[0023] The diagonal strap 5 extends diagonally forward from the strap body 1. Furthermore, the angle between the diagonal strap 5 and the lateral side is 20°-30°. The diagonal strap 5 can fix the relative position of the palm and wrist joint, and help maintain the relatively hyperextended hand position.

[0024] The outer ends of the first horizontal bandage 4, the diagonal bandage 5, and the second horizontal bandage 6 are all equipped with Velcro. When in use, the bandages on the left and right sides are wrapped around the hand and temporarily secured with the Velcro. This maintains the wrist and hand position while securing the pressure monitoring tubing, preventing it from dislodging. This bandage is suitable for patients of different body types, can be used on either hand, and can be used while the patient is awake or under anesthesia.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
