Description

Hand rest holder for radial artery puncture

technical field

The invention relates to a hand rest fixing frame for radial artery puncture.

Background technique

Radial artery puncture is a technique often used in clinical work, which can be used for monitoring arterial blood pressure, interventional therapy and blood test. During the puncture, it is usually necessary to abduct the arm and fully expose the wrist for more convenient operation. Therefore, it is necessary to support and fix the arm position before performing the puncture operation.

At present, when performing radial artery puncture, there is no special support for radial artery puncture. Adults and children use temporary support boards or wooden boards to support the abducted arm during puncture. Soft objects are placed under the head to fully expose the wrist, and the palm is fixed on the hand support or wooden board with adhesive tape so that the arm does not shift during the puncture operation. Such a support method is cumbersome, and the arm is unstable, which is inconvenient for medical treatment. The operation of the personnel and the comfort of the patient are poor. Such an operation is not standardized and does not conform to the trend of modern medical development. Insufficient exposure of the wrist can affect the success rate of the puncture operation. Existing hand rests cannot adjust the position of the arm according to the arm lengths of different patients. The sensors are mostly fixed on the adjacent infusion stand with adhesive tape, which is inconvenient to adjust the position of the sensor according to the required height. the

Description of drawings

Fig. 1 is a structural schematic diagram of the present invention.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to Fig. 1, the present invention includes a hand support bar 2, a fixed clip 1, an elbow tray 3, a wrist tray 5, and a movable palm tray 6, and an elbow tray 3 and a wrist tray 3 are arranged in turn on the hand support bar 2 from left to right. Tray 5, one end of the handle bar 2 is provided with a fixed clip 1, and the other end of the handle bar 2 is provided with a movable palm tray 6. The handle bar 2 is connected with a telescopic drive frame 4.

The above-mentioned fixing clip 1 is a card slot structure, and there is a movable pull rod below, and there is a spring on the pull rod. When the pull rod is pulled, the fixing clip opens, and when the pull rod is released, the fixing clip closes. When fixing, the pull rod needs to be released The entire bracket can be fixed by biting the fixing clip on the beam beside the operating bed.

The above-mentioned fixed clip 1 is connected with the handle bar 2 through the movable shaft, so that the handle bar 2 can move in the horizontal direction.

Above-mentioned hand support bar 2 is made up of two flexible movable bars, can be adjusted according to the length of different patients' arms, and the hand support bar is the shortest 30 centimeters, and the longest can be stretched to 60 centimeters.
