Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an air bag fixing device used after radial artery puncture. Background Art
[0002] The radial artery is located between the brachioradialis tendon and the radial flexor carpi tendon. The existing invasive blood pressure can accurately reflect the patient's blood pressure. In major surgeries and critically ill patients in intensive care units, it is necessary to accurately grasp the patient's vital signs at any time. Blood pressure is one of the important vital signs. The change of arterial blood pressure at any time can be used to evaluate the blood perfusion status of important tissues and organs, and provide a reliable basis for anesthesia, intraoperative medication, and rescue of patients in intensive care units. Invasive blood pressure monitoring avoids the errors and lags of non-invasive blood pressure. Radial artery pressure measurement is a commonly used monitoring method for major surgeries and critically ill patients. It can monitor and read the blood pressure values of surgical patients in real time and accurately, so that the condition can be treated in the first time, which greatly improves the safety of surgery.
[0003] Radial artery puncture is a necessary means for radial artery pressure measurement. During radial artery puncture, the wrist joint is preferably in an everted position to fully expose the radial artery. However, because the radial artery is easily deformed at this position after radial artery puncture, resulting in inaccurate pressure measurement, it is necessary to fix this position for easy operation.

[0006] Preferably, a threaded barrel is provided in the middle of the slider, an adjusting rod is rotatably installed in the base, the adjusting rod passes through the two sliders, and two sections of threaded columns are provided on the adjusting rod, and the two sections of threaded columns are respectively matched and connected with the two threaded barrels.
[0007] Preferably, the wrist fixing mechanism includes two clamping blocks, the opposing surfaces of the two clamping blocks are arcuate structures, an inflatable airbag is arranged on the arcuate surface, a fixing block is arranged on the upper surface of the clamping block, a torsion column is screwed in the fixing block, the bottom of the torsion column is rotatably connected to a lifting plate, and the bottom of the lifting plate is connected to an air storage bag.
[0008] Preferably, the air storage bag is a retractable and elastic air bag structure.
[0009] Preferably, the air storage bag and the expansion air bag are connected via an air guide hose.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The utility model provides an air bag fixing device for radial artery puncture, wherein the patient's wrist is placed between two clamping blocks, and the sliders on both sides can be moved toward the middle by rotating the adjusting rod, so that the clamping blocks clamp the wrist, and then the torsion column is rotated to make it descend, so that the lifting plate presses the air storage bag downward, and the gas in the air storage bag is squeezed into the expansion air bag. The expansion of the expansion air bag can fill the gap between the clamping block and the wrist, so that the device can clamp the wrist tightly without hurting the wrist, and the use is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a diagram of the internal structure of the device of the utility model.
[0014] In the figure: base 1, slide groove 2, slider 3, threaded tube 4, adjusting rod 5, threaded column 6, clamping block 7, air storage bag 8, lifting plate 9, fixing block 10, torsion column 11, expansion air bag 12, air guide hose 13. DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1 to Figure 2 The utility model provides a technical solution: an airbag fixing device for radial artery puncture, comprising a base 1, the upper surface of the base 1 is stacked with two slide grooves 2, a slider 3 is movably arranged in the slide groove 2, a threaded tube 4 is arranged in the middle of the slider 3, an adjusting rod 5 is rotatably installed in the base 1, the adjusting rod 5 passes through the two sliders 3, two sections of threaded columns 6 are arranged on the adjusting rod 5, the two sections of threaded columns 6 are respectively connected with the two threaded tubes 4, and the two sliders 3 can be moved to the middle or to both sides by rotating the adjusting rod 5.
[0017] The slider 3 is a T-shaped structure. The top of the slider 3 is connected to a wrist fixing mechanism. The wrist fixing mechanism includes two clamping blocks 7. The opposing surfaces of the two clamping blocks 7 are arc structures. An inflatable airbag 12 is arranged on the arc surface. A fixing block 10 is arranged on the upper surface of the clamping block 7. A torsion column 11 is screwed inside the fixing block 10. The torsion column 11 can be raised and lowered by rotating it. The bottom of the torsion column 11 is rotatably connected to a lifting plate 9. The bottom of the lifting plate 9 is connected to an air storage bag 8. The air storage bag 8 is a retractable and elastic airbag structure. The air storage bag 8 and the inflatable airbag 12 are connected through an air guide hose 13. For the clamping block 7, the length can be appropriately extended to achieve a better fixing effect. The front end can even be extended to the palm and made into a shape that fits the front palm. In this way, the wrist is less likely to move. Because the clamping block 7 can be opened and closed and the inflatable airbag 12 can be inflated, it has little effect on the thickness of the arm. The device has strong applicability.
[0018] During actual use, the patient's wrist is placed between the two clamping blocks 7. The sliders 3 on both sides can be moved toward the middle by rotating the adjusting rod 5, so that the clamping block 7 clamps the wrist. Then, the torsion column 11 is rotated to make it lower, so that the lifting plate 9 presses the air storage bag 8 downward, and the gas in the air storage bag 8 is squeezed into the expansion air bag 12. The expansion of the expansion air bag 12 can fill the gap between the clamping block 7 and the wrist, so that the device can clamp the wrist tightly without hurting the wrist, which is more convenient to use.
