[0002] Due to the disease requirements of critically ill patients, hemodynamic monitoring is needed. After indwelling an arterial needle, a pressure suit sensor is connected. In hemodynamic monitoring, blood indicators are often monitored. Under normal circumstances, a syringe is used to draw blood and then injected into a blood collection tube for inspection. In this process, the blood is likely to contaminate medical staff. It is also easy to cause needle - stick injuries when injecting into the blood collection tube through a syringe. Content of the Utility Model
[0003] The utility model provides a needle - proof arterial blood sampler to solve the problems that medical staff are easily contaminated and needle - stick injuries are likely to occur during the blood sampling process on an arterial indwelling needle. At the same time, the workload of nurses is reduced. Based on this, the utility model is completed.
[0004] The utility model provides a needle - proof arterial blood sampler, which includes a cylinder body 1. One end of the cylinder body 1 is open, and a blood sampling interface 3 is arranged at the closed end of the cylinder body 1. The blood sampling interface 3 is connected with a blood receiving needle 4. The blood sampling interface 3 and the blood receiving needle 4 are communicated. The connection part of the blood sampling interface 3 and the blood receiving needle 4 is fixedly connected with the closed end of the cylinder body 1. The blood sampling interface 3 is located outside the cylinder body 1 and is used to connect the external interface of the arterial indwelling needle. The blood receiving needle 4 is located inside the cylinder body 1. After placing a blood collection tube inside the cylinder body 1, it is punctured and connected with the blood receiving needle 4 for blood sampling.
[0005] Further, a rubber cap 2 is arranged on the blood sampling interface 3. The rubber cap 2 can be removed when needed and covered after use.
[0006] Further, a rubber sleeve 5 fixed to the cylinder body 1 is arranged on the blood receiving needle 4 to wrap the blood receiving needle 4 to avoid contamination. During blood sampling, the rubber sleeve 5 is squeezed by the blood collection tube to expose the blood receiving needle 4. After blood sampling is completed, the blood receiving needle 4 is wrapped again to avoid blood spillage and prevent the blood receiving needle 4 from being contaminated.
[0007] Further, two semicircular hand - held handles 6 are arranged at the open end of the cylinder body 1. When using a blood collection tube for blood sampling, they assist the user in grasping the cylinder body 1, making the blood sampling process labor - saving.
[0008] Further, the cylinder body 1, the rubber cap 2 and the hand - held handle 6 are made of transparent materials, which is convenient for users to observe the usage situation of the device.
[0009] Compared with the prior art, the technical advantages of the needle - proof arterial blood sampler provided by the utility model are as follows:
[0010] A kind of anti - puncture arterial blood sampler provided by the utility model uses a cylinder 1, and a blood collection interface 2 is arranged on the cylinder 1, avoiding using a syringe to draw blood from an arterial indwelling needle, which is convenient for patients to operate. A blood collection needle 4 is arranged inside the cylinder 1. When using a blood collection tube to collect blood specimens, the risk of needle stick injury is avoided, and it is convenient to operate, and the workload of medical staff is also reduced.
[0011] Other features and advantages of the utility model will be described in detail in the subsequent specific implementation part. Brief Description of the Drawings

[0016] To further elaborate on the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manner, structure, features and their effects of the utility model as follows.
[0017] Embodiment An anti - puncture arterial blood sampler
[0018] As Figures 1-3 shown,
[0019] This embodiment provides an anti - puncture arterial blood sampler, including a cylinder 1. One end of the cylinder 1 is open, and a blood collection interface 3 is arranged at the closed end of the cylinder 1. The blood collection interface 3 is connected with a blood collection needle 4. The blood collection interface 3 and the blood collection needle 4 are communicated, and the connection part of the blood collection interface 3 and the blood collection needle 4 is fixedly connected with the closed end of the cylinder 1. The blood collection interface 3 is located outside the cylinder 1 and is used to connect the external interface of the arterial indwelling needle. The blood collection needle 4 is located inside the cylinder 1. After placing the blood collection tube inside the cylinder 1, it is puncture - connected with the blood collection needle 4 for blood collection.
