An auxiliary device for radial artery puncture

technical field

The utility model relates to a puncture auxiliary device, in particular to a radial artery puncture auxiliary device, which belongs to the technical field of medical auxiliary devices.

Background technique

The radial artery is located between the brachioradial tendon and the flexor carpi radialis tendon. There is a palpable pulse of 2cm from the wrist to the distal radial head. Radial artery puncture is widely used in the anesthesiology department to monitor the real-time arterial blood pressure of surgical patients. However, the radial artery When puncturing, rely on the hyperextended position of the wrist. During the puncture, the patient is supine, the upper limbs are kept in a natural position, the palms are kept upward, and the wrist is fully exposed. A rolled up sterile sheet or gauze is used as a pad on the back of the wrist, and the wrist is hyperextended for 30 minutes. °, and at the same time tape the fingertips in a horizontal position to reduce vascular distortion. However, this method is a blind puncture method that only relies on the radial artery pulse as a sign, and the success rate depends on the operator's clinical experience. It is not uncommon for the catheter to be difficult to insert after successful puncture, and it is easy to damage the flexor retinaculum and small radial artery during puncture. superficial branches. It can be seen that there is a clinical lack of an auxiliary device to help fix the wrist during radial artery puncture, improve the stability and success rate of puncture, and improve patient satisfaction.

Chinese patent CN103536336A discloses a radial artery puncture fixed compression plate, which includes a plate body; the plate body includes an arm plate and a hand plate; the hand plate is bent between the end of the arm plate and the arm plate. The two ends of the wrist joint are respectively fixed by the hand plate and the arm plate, and the best puncture position of the wrist is provided before puncture to improve the success rate of radial artery puncture; the best position of the wrist joint is maintained during monitoring, the occurrence of tube bending is reduced, and the position of readjustment during monitoring is reduced And fix the puncture needle again to reduce interference to blood pressure monitoring and surgery. A detachable compression block is set on the arm plate. After sufficient gas is inflated at the end of the radial artery pressure measurement, the compression airbag and the compression block can provide appropriate pressure to compress the puncture point, reducing personnel waste, and the pressure is more stable and suitable, which can Realize soft compression of the airbag, uniform pressure, no crushing injury, better compression effect, avoid cross-infection caused by repeated use, wide adaptability, safety and reliability. The device is mainly used to assist in fixing the wrist, and does not have auxiliary positioning and adjustment functions for the puncture process.

There are 4 finger card sleeves arranged side by side.

Angle and distance scales are arranged on the upper surface of the wrist support column and the bridging bridge.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. In this device, the two sides of the bridge and the wrist support column are connected by rotation, and the bridge can be rotated to adjust the position and angle of the bridge. At the same time, several parallel grooves are set on the bridge, and the above-mentioned The length direction of the groove is parallel to the length direction of the bottom plate, so the puncture needle can be placed in different grooves to further adjust the puncture position. In addition, the wrist support column and the upper surface of the bridging bridge are provided with angle and distance scales, so that in The puncture position and angle can be adjusted precisely during the puncture process. At the same time, the setting of the bridge is conducive to the fixation of the puncture needle during puncture. With the puncture needle with a scale, it is beneficial for the operator to grasp the depth of the needle during puncture, which helps to improve the accuracy of puncture. stability and success rate.

2. In this device, the wrist support column replaces the traditional method of using a rolled-up disinfection sheet or gauze roll pad on the back of the wrist. The wrist support column can keep the wrist hyperextended, and the four finger sleeves set at the same time can be more convenient Hold your fingers firmly.

3. In this device, the length of the bottom plate is adjustable, so it can be used by patients with different body types. At the same time, the degree of wrist hyperextension can be adjusted by adjusting the length of the bottom plate.

4. The device is simple in structure, easy to use, and has a specific adjustment function, which greatly improves the puncture effect.
