Description

Blood gas analysis radial artery collection adjustable stent

technical field

The utility model relates to a medical product, in particular to an adjustable support for radial artery collection for blood gas analysis.

Background technique

The change of human blood gas can be obtained by blood gas analysis technology, and blood gas analysis is of great value in diagnosing and guiding the treatment of acid-base disorders in emergency critically ill patients, and in judging respiratory, circulatory and renal insufficiency, especially for hypoglycemia and hypokalemia The patient is a quick and convenient diagnostic measure, and the most commonly used part in the emergency department is the radial artery, because of its superficial position and easy puncture success. The stent disclosed in 201220622310.3, because it is fixed in an arc shape, cannot adjust the angle according to different patients. Different patients cannot stretch the wrist well, and the radial artery is not exposed enough, which is not conducive to puncture, thereby reducing the success rate.

Contents of the invention

The purpose of this utility model is to provide a simple structure, convenient and quick to use, which can be aimed at different patients, while ensuring sufficient exposure of the radial artery, and can also take into account the comfort of the patient's blood gas analysis. Insufficiency of existing technology.

The utility model realizes its purpose technical scheme is:

An adjustable bracket for blood gas analysis radial artery collection, including a forearm bracket and a palm bracket, the forearm bracket and the palm bracket are rotationally connected through a rotating shaft, and nuts are respectively provided at both ends of the rotating shaft, and the two nuts respectively abut against the forearm bracket On the frame and palm bracket, one side of the forearm bracket has a fixing belt, the top of the fixing belt has a fixing plug, the two sides of the fixing plug have stops, and the other side of the forearm bracket is arranged with a fixing slot. There are grooves on both sides to match the stoppers. The surface of the fixing belt is cushioned. One side of the palm bracket is fixedly connected with a restraint belt. There are several groups of fixing holes uniformly opened on the restraint belt. The other side of the palm bracket There are protrusions matched with the fixing holes, and the surfaces of the forearm bracket and the palm bracket are also provided with soft pads.

The top side of the forearm bracket has a first protrusion, the top side of the palm bracket has a second protrusion matched with the first protrusion, and the rotating shaft passes through the first protrusion and the second protrusion respectively, The forearm bracket and the palm bracket are rotatably connected.

The nut also has a rubber washer.

The material of the cushion can be medical sponge or medical silica gel.

The ends of the forearm bracket and the palm bracket have arc angles.

The fixing strap is elastic cloth material

After adopting the above-mentioned structure, since the forearm bracket and the palm bracket are rotatably connected through the rotating shaft and fixed by nuts, such a structure enables the utility model to adjust the angle between the forearm bracket and the palm bracket according to different patients, In this way, regardless of the thickness of the arm, the radial artery can be fully exposed to the patient.

Simultaneously, because the top end side of described forearm bracket has the first protrusion, the top end side of the palm bracket has the second protrusion that cooperates with the first protrusion, and the rotating shaft passes through the first protrusion and the second protrusion respectively. The two protrusions make the forearm bracket and the palm bracket realize rotational connection. The advantage of this structure is that because the utility model is most often used in emergency rooms, the angle between the forearm bracket and the palm bracket can be quickly adjusted. It is extremely important to allow the puncture to be carried out quickly. The first protrusion and the second protrusion have through holes. Since the rotating shaft passes through the first protrusion and the second protrusion respectively, the forearm bracket and the palm bracket are at ordinary times There is a slight movement margin between them, and a slight axial movement can be made along the rotating shaft. When in use, the medical staff only need to tighten the nut after adjusting the angle to compress the forearm bracket and the palm bracket , so that they fit closely, so that the angle is fixed, which is not only convenient, but also fast and saves time. On the other hand, because most of the patients in the emergency room are in critical condition and the environment is complicated, medical instruments need to be disinfected and cleaned frequently. During disinfection, You only need to unscrew the nut and pull out the rotating shaft to separate the forearm bracket from the palm bracket, which not only facilitates the work of medical staff, but also cleans each part more thoroughly.

One side of the palm bracket is fixedly connected with a restraint belt, and several groups of fixing holes are uniformly opened on the restraint belt, and the other side of the palm bracket has protrusions matched with the fixing holes, and the surface of the forearm bracket and the palm bracket It also has soft pads. The advantage of this structure is that when an unconscious patient cannot follow the doctor's advice to adjust the wrist, the medical staff can put the back of the patient's hand as close as possible to the palm bracket, and through the cooperation of the restraint belt and the protrusion, make the wrist The patient's palm is fixed, and then the angle is adjusted. At the same time, since one side of the forearm bracket has a fixed belt, the top of the fixed belt has a fixed plug, and both sides of the fixed plug have stops. The other side of the forearm bracket is arranged with a fixed plug. There are grooves on both sides of the fixed slot to match the stoppers, and the surface of the fixed belt has soft pads. This design, which is similar to a schoolbag buckle, only needs to insert the fixed plug into the fixed slot when in use. The arm of the patient is fixed on the forearm bracket, which not only saves time, but also ensures that the utility model is firmly fixed on the patient's forearm and does not fall off, which is convenient for medical staff to perform puncture operations. The surface of the belt has soft pads, so that patients, especially children, will not feel cold when they touch the utility model, and feel comfortable when the angle is adjusted, so that the patient's mind can be relaxed as much as possible, the wrist is not stiff, and the radial artery can be fully exposed. the goal of.

And described nut also has rubber washer, and rubber washer not only can make nut more compact compact forearm bracket and palm bracket, is unlikely to loosen, can play protection forearm bracket and palm bracket simultaneously, makes use Life extension.

After the above-mentioned technical scheme is fully implemented, the utility model has the characteristics of reasonable structure, convenient use, and the ability to fully expose the radial artery and facilitate puncture for different patients, which is self-evident.
