Description
Technical Field
The utility model belongs to the technical field of medical instrument's technique and specifically relates to a needle is prevented stinging and is kept somewhere to withstand voltage type.
Background
The disposable venous indwelling needle can avoid the injury of blood vessels caused by multiple times of puncture, reduce the pain of patients, and reduce the operation intensity of medical care personnel, and is generally used clinically. However, when the needle tube is withdrawn after the puncture of the indwelling needle is completed, the medical care personnel may be punctured by the needle tip to cause a certain trauma to the medical care personnel, and if the blood stained with the needle head contains infectious viruses, the needle tube may bring great harm to the medical care personnel. In addition, the waste needle with blood exposed to air can cause environmental pollution. When the needle tube is pulled out after the puncture of the anti-needle type remaining needle is finished, the needle tip can be effectively blocked, so that the effects of effectively preventing blood-borne infectious diseases and blood-borne pollution caused by the puncture wound are achieved.
At present, in practice, the mode that the needle point is wrapped by stainless steel elastic sheets, cards, clamping sheets and the like to reduce the puncture risk or blood pollution is adopted in the anti-puncture venous indwelling needle, the mode mainly utilizes a puncture needle tube to support a metal sheet, the anti-deformation performance of the metal sheet is not provided at the moment that the needle point exits the metal sheet, the metal sheet returns to the initial state, the needle point can be blocked, however, an unsealed groove is formed in a protection device of the needle point, and therefore, the anti-puncture protection device can only play a role in preventing the needle point from being punctured, and the possibility of blood overflow cannot be completely avoided. Secondly, in the process of puncturing by using the remaining needle, the needle seat is mostly not fixed firmly, which causes the condition of unbalanced force during puncturing. Moreover, the existing remaining needle has a complex structure for preventing acupuncture, increases the production and manufacturing cost and reduces the use safety of medical care personnel.
SUMMERY OF THE UTILITY MODEL
