Description

Shapeable radial artery puncture and pressure measurement fixing device

Technical Field

The utility model discloses a shapeable radial artery puncture and pressure measurement fixing device, in particular to the technical field of medical instruments.

Background

Invasive arterial blood pressure monitoring is a method for directly measuring the blood pressure in an artery by placing an arterial catheter in the artery, can continuously monitor the dynamic change process of the blood pressure, has the characteristics of accurate and reliable numerical value and value taking at any time, and provides dynamic hemodynamics basis for the treatment of critically ill patients. Meanwhile, the collection and analysis of arterial blood can be conveniently and rapidly provided. Is a clinical operation technical means widely applied to intensive care units, anesthesia departments and emergency departments. Among them, the radial artery has the advantages of shallow surface of the anatomical position, convenient relative puncture and fixation, easy compression hemostasis and the like, and is often used as the preferred puncture position. In actual clinical work, particularly under the condition of emergency treatment, the patient has poor fitting degree and poor wrist stability, and the hand shape is difficult to fix, so that the method is very unfavorable for successfully puncturing the radial artery. Once puncture fails, local hematoma is easy to cause, and multiple punctures can cause the situations of stenosis, occlusion, spasm and the like, thereby increasing the pain of patients and simultaneously delaying the treatment time. In order to facilitate the contact with the pulse to achieve a high puncture success rate, the puncture usually needs to be performed by means of another object (such as a cloth sheet and a pillow) to be padded under the wrist joint of the patient or an assistant to cooperatively fix the forearm of the patient so that the wrist joint is stretched in a back way, so as to fully expose the puncture site. Although the material is simply drawn in the process, the fixing effect is not good enough, the comfort level of the patient is poor, the wrist anatomy characteristics are not met, time and labor are wasted, and the labor intensity of medical personnel is increased. After the puncture is successful, the radial artery catheterization needs to be connected with a transducer, a flushing infusion apparatus, a monitor and the like so as to achieve the purpose of continuously measuring pressure. If the flushing infusion apparatus is not fixed well, the traction is easy to cause, which can cause the radial artery catheter to slip accidentally and cause unnecessary injury. Meanwhile, the wrist part is usually bent unconsciously, so that the radial artery catheterization is easy to be broken, displaced and thrombus is formed, and the normal and accurate invasive effective monitoring of the arterial blood pressure cannot be realized. Therefore, there is a need for a device that integrates radial artery puncture and continuous manometry. On one hand, the success rate of radial artery puncture is guaranteed under the natural and comfortable condition of a patient, and on the other hand, the arm and the wrist of the patient are effectively fixed and the infusion apparatus is washed, so that the radial artery catheterization is guaranteed, the blood pressure of the invasive artery is effectively and continuously monitored, and the safety of the patient is guaranteed.
