Embodiment 1

[0031] Embodiment one, such as figure 1 , figure 2 As shown, this embodiment proposes a radial artery blood collection device, including a front box 1, a rear box 2 and a tourniquet 3, the front box 1 is connected to the rear box 2, and the rear box 2 can be turned over to the front box The top of the body 2 is fastened together with the front box body 1. Such a design can make the whole radial artery blood sampling device form a whole, which is convenient to carry. In order to enhance the stability of the blood collection device, matching latches 4 are provided on the front case body 1 and the rear case body 2 . In addition, in order to carry the blood collection device conveniently, a handle can also be provided on it.

[0032] The front box body 1 of the present embodiment is provided with accommodating groove 19, and it is used for accommodating forearm bracket 11, and the rear end of forearm bracket 11 is pivoted with front box body 1, and forearm bracket 11 is provid...

Embodiment 2

[0040] Embodiment two, such as Figure 4 As shown, the difference between the second embodiment and the first embodiment is that the lifting device of this embodiment includes a rail and a support rod 16 arranged at the bottom of the accommodating tank. Wherein, the clamping rail is provided with several clamping slots; one end of the support rod 16 is pivotally connected to the back of the forearm bracket 11 , and the other end is buckled on the clamping slots. The height of the forearm bracket 11 is adjusted by manually adjusting the height, which is convenient and quick. Specifically, the clamping rail of this embodiment is a rack 15, the number is 2, or multiple racks, or a rack whose width is less than or equal to the width of the accommodation groove 19, and the support rod 16 is rectangular. During adjustment, first the forearm bracket 11 is held up, and the swing support rod 16 is adjusted inwards or outwards to a suitable height as required and the support rod is pla...

Abstract

The invention belongs to the field of medical apparatuses and particularly relates to a radial artery blood collection device, comprising a front box and a rear box. The front box is provided with a front arm carrier receivable in the front box, lifting height of this carrier is adjusted through a lifting device, the carrier is provided with a recessed carrying cavity, and two sides of the carrying cavity are provided with clamping devices capable of moving transversely to clamp the arm. Compared with the prior art, the radial artery blood collection device has the front and rear boxes shafted, and the rear box can turn over the front box and fastens to the front box so that the whole device is simple in structure and convenient to carry; in addition, the clamping devices are disposed on two sides of the carrying cavity of the front arm carrier, the arm of a patient can be automatically clamped, clamping force of clamping sheets is controlled in a suitable pressure range, blood collection is achieved, and the discomfort in the patient caused by excess clamping of the clamping sheets for the arm is also avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a radial artery blood collection device. Background technique [0002] Collecting arterial blood samples for blood gas analysis and judging the oxygenation status of patients is the most common nursing technique in clinical practice, and it is also a difficult operation. We often use the femoral artery, radial artery, and dorsalis pedis artery for blood collection. Because radial artery blood collection is not affected by climate, environment, and patient position, it does not need to undress, it is easy to expose the puncture site, and it is easy to accept by nurses and patients, so it is widely used in clinical practice. [0003] However, because the radial artery is thin and difficult to puncture, the success rate of one-time puncture is low according to conventional puncture methods. In view of this, often by changing the placement method of the patient's arm, the success r...
