Description

Technical Field

[0001] The utility model relates to the technical field of medical assistance, in particular to an air bag positive pressure protection mechanism. Background Art

[0002] Prior to CT angiography, venous indwelling needle puncture is generally required. When selecting the puncture site, the median cubital vein is often selected to ensure the puncture success rate and angiography effect. A Chinese utility model patent with announcement number CNC219230056U discloses an elbow airbag protection mechanism, including an airbag shell, which can protect the patient's elbow, and the airbag can be suitable for patients with different arm thicknesses by adjusting the inner diameter between the fixing belts, thereby improving the practicality of the airbag when used.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in the above-mentioned structure, the overall width of the airbag shell is small, and it can only be located at the patient's elbow. During the examination, the patient needs to lie flat and raise both arms above the head and quickly inject the contrast agent. When raising the arms, the elbows cannot be bent, which will cause the indwelling needle to bend and block the contrast, and cause imaging obstacles. The above-mentioned mechanism cannot ensure that the patient's arms are horizontal and not bent. For this reason, we designed an airbag positive pressure protection mechanism. Utility Model Content

[0004] In order to solve the technical problem that the indwelling needle is bent and blocked due to bending of the elbow when raising the arm, thus causing imaging obstruction, the utility model provides an airbag positive pressure protection mechanism.

[0005] The utility model is implemented by the following technical scheme: an airbag positive pressure protection mechanism, including two symmetrically arranged support arc seats, each of which is provided with fixing belts at both ends above the left and right ends, a limited airbag is provided at the lower end of the fixing belt, a plurality of evenly distributed support columns are inserted between the two support arc seats, and a support assembly is installed between the plurality of support columns.

[0006] As a further improvement of the above scheme, the support assembly includes a support arc plate, a protective pad is glued on the top of the support arc plate, a fixing sleeve is integrally arranged on the top of the support arc plate, a compression airbag is arranged at the lower end of the fixing sleeve, the support arc plate is used to place the patient's elbow, the compression airbag can be expanded to compress and fix the upper part of the elbow, and the compression airbag still has a certain flexibility after expansion, and will not cause compression injury to the patient's elbow.

[0007] As a further improvement of the above scheme, the left and right ends of the supporting arc plate are integrally formed with mounting parts, and the mounting parts are formed with plug-in holes through the front and back, and the supporting columns at the left and right ends are plugged into the plug-in holes and fixed thereto, so as to facilitate the installation and disassembly of the supporting arc plate.

[0008] As a further improvement of the above scheme, an air inlet valve and an exhaust valve are arranged above the fixing belt and the fixing sleeve, and the lower ends of the air inlet valve and the exhaust valve pass through the fixing belt and the fixing sleeve to be connected with the corresponding limiting airbag and compression airbag below. The air inlet valve is a one-way valve, which can expand the limiting airbag and the compression airbag through an external inflation device, so as to compress and fix the patient's arm.

[0009] As a further improvement of the above scheme, the upper surface of the support arc seat is recessed downward to form an arc-shaped surface, and a support pad is arranged inside the arc-shaped surface. The upper surface of the support pad is flush with the upper surface of the protective pad, which is convenient for the patient's arm to be placed above the support pad and the protective pad. The support pad and the protective pad themselves are relatively soft, which improves comfort and will not cause pressure injuries to the patient's arms.

[0010] As a further improvement of the above scheme, a plurality of evenly distributed mounting holes are formed through the front and rear ends of the support arc seat, and the mounting holes are in an arc-shaped array. The front and rear ends of the support column are respectively inserted into the mounting holes of the two support arc seats, and the outer surfaces of the four middle support columns are in contact with the lower surface of the support arc plate. The clearance between the support column and the mounting hole is matched, and the distance between the two support arc seats can be changed as needed. It is suitable for patients of different heights and is easy to install and disassemble quickly.

[0011] As a further improvement of the above scheme, the left and right ends of the support arc seat are provided with installation frames, and the installation frames are penetrated from top to bottom to form a through-hole, and the lower end of the fixing belt passes through the through-hole and bends upward, and is connected to the upper part of the inner part of the fixing belt. The inner sides of the two ends of the fixing belt can be provided with multiple rows of snap-on buckles or Velcro as needed, so that the two ends can be pasted and fixed by themselves, and this can change

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model provides two support arc seats, and the two support arc seats are respectively located at the front and rear sides of the patient's elbow.
