Abstract

The utility model discloses a painless blood sampling pen. The painless blood sampling pen comprises a depth adjusting device, a pop-up return needle device and a needle discharging device. The depth adjusting device comprises an adjusting cap and an adjusting sleeve, wherein a functional clamping position and an adjusting convex point are formed on the upper portion of an outer circumference surface of the adjusting sleeve, threads are formed on the lower portion of the outer circumference surface of the adjusting sleeve, and an annular clamping groove which is matched with the functional clamping position and longitudinal grooves which are matched with the adjusting convex point are formed in an inner side circumference surface of the adjusting cap. The adjusting cap is screwed into the adjusting sleeve, locks the adjusting sleeve and drives the adjusting sleeve to rotate in a circumferential direction. The painless blood sampling pen has the advantages that due to the fact that the adjusting convex point can move on tap positions formed by the ten longitudinal grooves in the adjusting cap, the painless blood sampling pen is large in adjusting depth range, small in adjusting separation distance, high in precision and capable of effectively reducing unnecessary puncture depth, and thereby painless blood sampling is achieved. In addition, double wing guide rails of a pen core are guaranteed to slide on an inner wall on two sides of an inner barrel stably, and the stability is strengthened. The painless blood sampling pen is simple in structure, convenient to use, beautiful in appearance and comfortable in hand feel.

Description

Painless blood collecting pen

Technical field

This utility model relates to a kind of medical appliance; Particularly relate to a kind of painless blood collecting pen that the micro blood sample is provided.

Background technology

Blood collecting pen is the medical apparatus of taking micro blood at finger tip or arm, and the blood sample of trace is provided for a diabetics people detection blood glucose.

Mainly contain two class blood collecting pens on the medical market at home and abroad at present, the first is the plain edition blood collecting pen, this is simple in structure, consisted of by depth adjustment, catapult-launching gear, pen container three parts, during use blood taking needle packed into pen core needle tray in the blood collecting pen, be loaded on depth adjustment, and carry out the paracentesis depth adjusting of 5 gears; Pull back pen container and load, and with blood collecting pen cap for brush termination by being pressed in finger or the suitable position of arm, launch after the pressing keys and get blood, after blood sampling is finished, turn on the cap for brush, need directly blood taking needle to be taken out with hands and abandon.But the second is withdraw of the needle type blood collecting pen, the structure relative complex, operating position is similar to the first blood collecting pen, its difference mainly is after blood sampling is finished, turn on the cap for brush, need not directly to take out blood taking needle with hands, abandon but by device on the blood collecting pen blood taking needle drawn off, but that the relative the first plain edition of the second withdraw of the needle type blood collecting pen blood collecting pen uses is safer, convenient.But all there is following shortcoming in above-mentioned two types blood collecting pen: pain is large during blood sampling, less stable, and production cost is high.
