Safe blood collecting and sample reserving device capable of preventing blood dropping

Abstract

The invention relates to a safe blood collecting and sample reserving device capable of preventing blood dropping. The device is characterized in that: an easily bent type conducting pipe is connected between a sealed type blood collecting needle and an anti-coagulation whole blood bag through a tee joint; a sample reserving blood bag is connected at the lower end of the conducting pipe; a needle sting protection housing is movably arranged outside an upper conducting pipe of the sealed type blood collecting needle; the sampling socket of the sample reserving blood bag comprises a puncture needle, a blood preventing housing and a hand-hold jacket; and the front opening end of the needle sting protection housing can be inserted into the hand-hold jacket in an interference fit mode. After blood collection and sample reservation are finished, the needle sting protection housing is moved forwards along the conducting pipe, thus the sealed type blood collecting needle, the puncture needle and the like are sealed in the needle sting protection housing and the hand-hold jacket by utilizing the insertion fit of the needle sting protection housing and the hand-hold jacket. The safe blood collecting and sample reserving device has a simple and reasonable structure, is convenient in operation and use, avoids the exposure of the sealed type blood collecting needle and the puncture needle, prevents blood from flowing out of the blood collecting part, reduces the environmental pollution caused by blood and the risk of disease propagation caused by blood, and guarantees the blood collecting safety and the operation safety of medical care personnel.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for preventing blood dripping and safe blood collection and sample retention. Background technique [0002] We know that a disposable blood collection device is a medical product commonly used in clinical practice to collect blood from the human body. In the process of use, in addition to achieving the principle of safety and effectiveness for the collected person, it is also necessary to avoid harm to the operator, even if Yes these hazards are potential. After the traditional blood collection device is used, the protective cap of the blood collection device and the sampling device is removed, and the needle tube is exposed. When handling these medical wastes, the exposed and sharp needle point will pose a potential threat to the operator. In order to protect the safety of the operator during use, some blood collection devices and sampling devices are currently equipped with protect...

AI Technical Summary

Problems solved by technology

In order to protect the safety of the operator during use, some blood collection devices and sampling devices are currently equipped with protective devices, which are used to protect the needle tip after use, but the additional devices are generally set up separately, which is not convenient for medical staff to operate ,use

There will still be blood dripping from the blood collection site during use, and there is a risk of blood pollution to the environment and blood-borne diseases
