Description

Technical Field

[0001] This utility model relates to the field of positioning pads, and in particular to a radial artery puncture positioning pad with a replaceable sterile towel module and a fixing function. Background Technology

[0002] The radial artery is one of the terminal branches of the brachial artery, slightly smaller than the ulnar artery. It is approximately 21.2 cm long with an initial outer diameter of about 0.3 cm. Radial artery puncture is a medical procedure primarily used to collect arterial blood for blood gas analysis, invasive arterial blood pressure monitoring, and, in specific cases, interventional treatments. Clinically, due to the radial artery's thinness and the difficulty of puncture, the wrist is often elevated from the back of the hand to make the intended puncture site more prominent, facilitating a smooth puncture.

[0003] Currently, when performing radial artery puncture, the wrist is mainly elevated using soft pads or appropriately shaped water bags. However, these items have relatively limited structure and function: firstly, they cannot adequately stabilize the patient's hand, especially in children undergoing radial artery puncture, as children are prone to crying and movement, making rapid and accurate puncture difficult when the hand is not properly stabilized; secondly, these items cannot quickly provide a sterile environment for radial artery puncture, thus causing inconvenience for medical personnel. Therefore, it is necessary to research a solution to address these problems. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a radial artery puncture positioning pad with a replaceable sterile towel module and a fixing function. It can effectively solve the problem that the existing radial artery puncture method, which uses soft pads or appropriately shaped water bags to elevate the patient, cannot properly fix the hand and causes inconvenience to medical staff.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A replaceable sterile towel module with a fixing function for radial artery puncture positioning pad includes a base, a biomimetic protrusion, and a sterile towel module. The base includes a main body, a front extension, and a rear extension. The front extension extends forward integrally from the front side of the main body, and a front fixing mechanism for fixing fingers is provided on the surface of the front extension. The rear extension extends rearward integrally from the rear side of the main body, and a rear fixing mechanism for fixing the arm is provided on the rear extension. The biomimetic protrusion is disposed on the surface of the main body, and a positioning groove is recessed on the surface of the biomimetic protrusion. The front and rear ends of the positioning groove extend to the front extension and the rear extension, respectively. The sterile towel module is adapted to the positioning groove and can be removably embedded in the positioning groove for positioning.

[0007] As a preferred embodiment, the front fixing mechanism includes a first fixing band for fixing the thumb and a second fixing band for fixing the other four fingers. Both ends of the first fixing band and both ends of the second fixing band are fixedly connected to the front extension to form two slots for the fingers to pass through.

[0008] As a preferred embodiment, the rear fixing mechanism includes a strap and a buckle. One end of the strap is fixedly connected to one side of the rear extension, and the buckle is connected to the other side of the rear extension via a connecting strap. The buckle and the tail end of the strap are detachably connected.

[0009] As a preferred embodiment, the biomimetic protrusion has upward-protruding baffles on both the left and right sides of its surface, and a receiving groove is formed between the two baffles for the wrist to be placed and positioned, so as to better position the wrist.

[0010] As a preferred option, the base is made of plastic or carbon fiber and has a flat structure to ensure structural strength while also being lighter.

[0011] As a preferred embodiment, a support frame extends integrally upward from the main body. The biomimetic protrusion is made of silicone and is molded and fixed on the main body. The support frame is embedded in the biomimetic protrusion, so that the biomimetic protrusion and the base are firmly connected, not easily damaged, and have a longer service life.

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0013] By using biomimetic protrusions to elevate the wrist, and employing a front fixation mechanism to secure the fingers and a rear fixation mechanism to secure the arm, the hand is securely fixed to the product, enabling medical personnel to perform radial artery puncture quickly and accurately. Furthermore, the inclusion of a sterile drape module allows the top sterile drape to be removed before proceeding to the next radial artery puncture, quickly providing a sterile environment and facilitating the procedure for medical personnel. The product boasts a rational overall design, diverse functions, and is extremely convenient to use.

[0028] Please refer to Figure 1 and Figure 2 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a base 10, a biomimetic protrusion 20, and a sterile towel module 30.

[0029] The base 10 includes a main body 11, a front extension 12, and a rear extension 13. The front extension 12 extends forward integrally from the front side of the main body 11, and a front fixing mechanism 40 for fixing fingers is provided on the surface of the front extension 12. The rear extension 13 extends rearward integrally from the rear side of the main body 11, and a rear fixing mechanism 50 for fixing the arm is provided on the rear extension 13. In this embodiment, the base 10 is made of plastic or carbon fiber, and the base 10 has a flat structure to ensure structural strength and also to make it lighter. Furthermore, a support frame 14 extends upward integrally from the main body 11, and the support frame 14 is T-shaped.

[0030] The biomimetic protrusion 20 is disposed on the surface of the main body 11.
