Pushing device for medical instrument

Abstract

The disclosure relates to a pushing device for medical instruments. The device comprises a housing, a delivery assembly, and a needle tip support, wherein the housing is located on a distal surface ofskin surface; the delivery assembly is configured to be movable between a proximal position in the housing away from the distal surface and a distal position near the distal surface, the delivery assembly comprises an engagement piece, and the engagement piece snaps to a medical instrument; the delivery assembly comprises at least two elastic arms and a restraining member, the elastic arm is engaged with a needle tip support, and the restraining member constrains the elastic arm, a biasing member is provided in the housing, and the biasing member blocks the restraining member when the delivery assembly moves from the proximal position to the distal position. With the device, when the medical instrument is applied to the skin surface, the needle tip support can be automatically retracted to the proximal position, thereby, damage of the pushing device to human tissues can be reduced, and safety of use of the pushing device can be improved.

Description

technical field [0001] The present disclosure relates to a pushing device for medical instruments. Background technique [0002] For clinical diagnosis or personal health monitoring, it is sometimes necessary to insert a medical device containing an analyte sensor under the skin to detect the concentration of a specific component (eg, glucose, salt, lactate, oxygen) in interstitial fluid. [0003] Especially, for diabetic patients, it is very necessary to monitor the glucose concentration of interstitial fluid in real time and continuously on weekdays, so as to reduce and reduce the occurrence of complications such as hypoglycemia and hyperglycemia in insulin-dependent diabetic patients. Usually, when the glucose concentration in the blood begins to decrease, the glucose concentration in the interstitial fluid decreases before the glucose concentration in the blood, thus indicating that the decrease in the glucose concentration in the interstitial fluid can make a prediction...

Problems solved by technology

However, such push devices currently on the market are often complicated to operate, with uncontrollable push force, position deviation during insertion, and improper insertion and application of analyte monitoring devices, resulting in poor user experience and unreliable monitoring results.
