Description

Radial artery fixing and pressurizing hemostasis device

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a radial artery is fixed and is pressed hemostasis device is related to.

Background

Arterial blood is blood flowing in arteries of the systemic circulation and in the pulmonary veins leading from the lungs back to the left atrium in the pulmonary circulation, and is more oxygenated, less carbonated and bright red in color. The arterial blood gas analysis can objectively reflect the nature and degree of respiratory failure, is a reliable method for judging hypoxia and carbon dioxide retention, and is widely applied to emergency treatment and ICU. The blood sampling site is generally selected from superficial, easy-to-touch and many collateral arteries of the body surface, such as radial artery, brachial artery, femoral artery, etc. In general, when arterial blood is collected for analysis, the radial artery is preferred, which has the following advantages: 1. the radial artery is positioned at the wrist part, the surface of the position is shallow, the puncture is easy, the cooperation degree of the patient is high, and the puncture part can be observed at any time; 2. ulnar artery as collateral circulation; 3. the damage degree to peripheral tissues is low, although brachial artery and femoral artery blood vessels are relatively thick, peripheral nerve blood vessels are rich, the anatomical position is complex, and the peripheral nerve damage, subcutaneous hematoma and other complications can be easily caused by careless operation.

After the radial artery blood sampling is completed, hemostasis needs to be performed on a radial artery puncture point in time, and manual hemostasis and instrument hemostasis are generally adopted clinically. The manual hemostasis mode adopts a finger pressing and bandage wrapping method, the controllability of the method is poor, bleeding is easily caused by too small pressure, radial artery occlusion and local skin and nerve injury are easily caused by too large pressure, and the requirement on experience of medical staff is high; in addition, the pressing time is long, the workload of medical staff is increased, and due to the instability of hand strength of a human body, the proper force is difficult to control when the hand is pressed for a long time, so that the time and labor are wasted, and the effect is poor; the hemostasis by compression is usually performed by a compression hemostasis device with a mechanical screw, but in practice, due to individual differences among patients, when a compression block of the radial artery mechanical screw compression hemostasis device is compressed, on one hand, the radial artery mechanical screw compression hemostasis device is easily compressed to an ulnar artery and surrounding tissues, and complications such as arm local congestion, blisters and the like are easily caused; on the other hand, the pressure application degree is not easy to control, the apparatus cannot sense the pulse bucket, and cannot apply pressure in a mode of balancing or slightly lower than the arterial systolic pressure value, so that a certain amount of blood cannot be guaranteed to pass through when the radial artery beats, the end limbs are numb easily, and the apparatus cannot be started fully and the self hemostasis natural force of the body can not be utilized.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provide a radial artery fixing and pressurizing hemostasis device with reasonable structure and scientific design.

The utility model discloses a radial artery is fixed and is pressed hemostasis device, its characterized in that the device include base, foam-rubber cushion, palm bandage and hemostasis bandage, and the base is right trapezoid, and the foam-rubber cushion covers at the base upper surface, connects palm bandage and hemostasis bandage on the base lateral wall, and the palm bandage sets up in hemostasis bandage the place ahead.

When the device is used, the palm center of the palm of a patient is upward, the back of the hand is tightly attached to the spongy cushion, fingers are positioned on the inclined plane of the base, the palm bandage is used to bypass the front end of the base, the palm center part is bound on the inclined plane of the base through the palm bandage, the wrist joint is positioned at the top of the base, the wrist is fully stretched and exposed, and then a radial artery blood sample can be collected; after collection, the wound is coated with sterile cotton and gauze, then the hemostatic bandage is rapidly passed through the wound position, the wrist of the patient is fixed on the top of the base, and the hemostatic bandage plays a role in pressurizing hemostasis.

The hemostatic bandage is characterized in that a groove is formed in the side wall of the base, an electronic timer is embedded into the groove, a loudspeaker is arranged on the electronic timer, the timing time of the electronic timer is set, after the hemostatic bandage is bound, a start button of the electronic timer is pressed, the electronic timer starts counting down, and after the time is up, the electronic timer gives an alarm sound, so that the hemostatic bandage can be unfastened, and the pressurized hemostatic device is removed.

The utility model discloses a radial artery fixes pressurization hemostasis device, rational in infrastructure, design science compare with other devices of the same type, have following advantage: 1. the wrist shape is attached, so that blood sampling is convenient; 2. the bandage is pressurized, the hemostatic effect is good, and the labor is saved; 3. has the timing function, and is convenient for checking the hemostatic effect in time.
