Problems solved by technology

[0003] At present, the blood collection device used clinically by children is generally a 1ml syringe used for intradermal injection, and the needle is a straight needle with a needle plug; most of the collection sites for children are the radial artery and femoral vein. During the collection of arterial blood in children, children should If you don’t move or cooperate, the pen-holding puncture will easily puncture the artery. If the situation is serious, the puncture may fail or even form a local hematoma.
[0004] The existing collection of children's arterial blood not only brings great pain to children, but also increases the work difficulty of medical staff

Embodiment 1

[0024] Embodiment 1: A kind of dedicated arterial blood gas collector for children, such as figure 1 As shown, it includes a syringe 1, an extension hose 2 and a needle body 22, and the syringe 1 stores freeze-dried heparin salt or other appropriate anticoagulants. One end of the extension hose 2 is fixedly connected to the needle body 22 , and the other end is provided with a connector plugged into the port of the syringe 1 . Utilizing the extended hose 2, during the shaking of the child, the medical staff adjusts the puncturing direction of the needle body 22 in time according to the shaking of the child, reducing the pain of the child due to puncture failure and improving the success rate of puncture.

[0025] Such as figure 1 Shown, the length of extension hose 2 is 3-5cm. In this embodiment, the length of the extension hose 2 is 4 cm, which is convenient for the medical personnel to operate arterial blood gas collection with one hand.

[0026] Such as figure 2 As sho...

Embodiment 2

[0028] Embodiment 2: A kind of dedicated arterial blood gas collector for children, such as image 3 As shown, the difference between Embodiment 2 and Embodiment 1 lies in that: the end of the needle body 22 close to the extension hose 2 is fixedly connected with a fin 21 , and the symmetrical side of the fin 21 is provided with a first groove 26 . Utilizing the first groove 26 stabilizes the finger pressing the tab 21 , reducing the occurrence of detachment of the finger from the tab 21 .

[0029] Such as image 3 As shown, the side of the syringe 1 is provided with a second groove 12 and at least one third groove 13 . In this embodiment, there are three third grooves 13 . Fitting the abductor pollicis brevis to the second groove 12 and fitting the finger to the third groove 13 makes the syringe 1 convenient to hold and operate.

[0030] Working principle: Using the extension hose 2, when the child is shaking, the medical staff can adjust the puncturing direction of the ne...

Abstract

The invention discloses an arterial blood gas collector special for a child, and relates to the technical field of medical instruments. The gas collector solves the problem that the child is active and uncooperative in the arterial blood collecting process, the holding puncture may break the artery easily and leads to puncture failure, even forming local hematoma. The arterial blood gas collectorincludes a syringe, an extension hose and a needle body. The needle body portion is provided with a needle wing convenient to operate and flexible to move, and an anticoagulant is stored in the syringe. One end of the extension hose is fixedly connected with the needle body, and the other end is provided with a connector connected to a syringe port in the insertion mode. The gas collector has theadvantage that a medical worker can conveniently collect the arterial blood of the child, enhance the success rate of the arterial blood collection of the child, and reduce the pains suffered by the child during the blood collection process.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a special arterial blood gas collector for children. Background technique [0002] The arterial blood sampler is mainly used for collecting and primary preservation of arterial blood samples for in vitro diagnostic tests. The needle of the blood collection device is equipped with a lock-type protective cover, which can be pressed to make the needle tube of the needle be fixed in the groove, so as to prevent accidental stabbing by the needle tip. At present, the arterial blood gas collection suitable for children is mainly a self-filling, single-use special safe arterial collection device containing freeze-dried heparin salt or other appropriate anticoagulants. [0003] At present, the blood collection device used clinically by children is generally a 1ml syringe used for intradermal injection, and the needle is a straight needle with a needle plug; mo...
