Description

Mechanism special for protecting venous blood taking needle
Technical Field
The invention relates to a medical apparatus, in particular to a mechanism special for protecting a venous blood taking needle.
Background
Intravenous blood taking needle belongs to the medical field disposable medical supplies. The intravenous blood taking needle with the hose is easy to hold when the needle handle blade is operated, the hose is easy to observe blood return, the puncture bottle stopper end is easy to puncture and pull out the blood taking tube at the far end of the vein, and the like, so that the intravenous blood taking needle is widely applied to clinical departments.
Medical institution management regulations require that blood collection operators safely protect the puncture needle tip after completing blood collection operation to prevent the risk of re-puncture and blood source pollution. The traditional practice is as follows: the plastic sheath of the blood taking needle is covered back, and the operation is difficult to implement because the sheath rolls off, or the risk of re-puncture is caused; the blood collection needle is inserted into special treatment objects or is thrown into a hard protection box, and the method needs to be specially configured by a clinical institution. In recent years, medical equipment manufacturers and clinical institutions have proposed many self-destruction and anti-needling safety blood collection needles, and few products which are clinically and practically well applied are provided. Mainly because of these designs:
1. the device mainly based on the ejection principle and the push-pull structure mainly based on the sliding blocks, the guide cylinders and the protective covers change the material structure and the production mode of the existing hose type intravenous blood taking needle, are used as medical instruments which are supervised according to the third type of high risk, and are difficult to completely consider the toxic effect and the sterilization effect of the material, and the safety and the effectiveness of the structural function at present; and meanwhile, the composite material is used as a low-value and easy-consumption material for mature production and use in the industry, and the design structures are relatively complex, so that the manufacturing cost and the economy are difficult to realize.
2. The device is also fixed on a needle seat or sleeved on a hose, and the clamping groove is buckled on the needle tube after blood collection is completed to realize needle penetration prevention. The technology has simple structure, does not change the main structure of the existing mature blood taking needle, and is easy to be injection molded and assembled. However, the risk degree of the clamping operation after use is consistent with that of the traditional operation of putting back the sheath, namely the clamping operation has the risk of directly touching the needle tip and blood, and complete protection is not really realized.
Disclosure of Invention
