Blood collecting device capable of being used by one hand

Abstract

The invention relates to a blood collecting device capable of being used by one hand. The blood collecting device is used to load and emit a blood pricking needle provided with a blood pricking needlehead. The blood collecting device comprises a rear unit and a front unit. The rear unit comprises a shell, a support rack, and a button. The support rack is elastically arranged in the shell and canmove back and forth in the shell and is combined with a blood pricking needle in a separable mode. The button can release the filled state of the support rack. The front unit comprises an arm nut anda front tip. The arm nut is combined with the terminal of the shell in a separable mode. The front tip is rotatingly combined with the arm nut so as to form a through hole where the head of the bloodpricking needle can go through. The support rack is provided with a slide knob that is exposed to the exterior of the shell and can make the support rack withdraw. The button is arranged in front of the slide knob.

Description

technical field [0001] The present invention relates to a blood sampling device for collecting a small amount of blood from a human body, and more specifically, to a blood sampling device that can be loaded with a sliding knob with one hand and used. Background technique [0002] A lancing device is a medical device that allows a small amount of blood to be expelled outside the skin. Such a blood collection device is mainly used by diabetics and the like who need to periodically measure blood sugar, but is also used in various fields where blood samples are required to be collected. [0003] The blood collection device uses the lancet inside to pressurize the capillary subcutaneous tissue such as fingers and toes, and at the same time discharge a small amount of blood to the outside of the skin. Using the blood thus discharged, the blood sugar of diabetic patients is measured with a blood glucose meter, or a blood analysis device capable of analyzing cholesterol and triglyc...

AI Technical Summary

Problems solved by technology

[0008] In order to load the lancet in the existing blood collection device, it is necessary to hold the main body with one hand and pull the rear end with the other hand, so it cannot be used with one hand, which is inconvenient

[0009] In addition, in the existing blood collection device, the needle depth adjustment part (the front tip, the inner tip, and the arm nut) is rotated to adjust the penetration depth of the lancet needle. At this time, it is difficult to manage the rotation feel and tolerance. Difficulty adjusting the needle penetration depth accurately and parts breakage or separation if the adjustment tip is turned too hard

[0010] In addition, in order to manufacture a strong product, the existing blood collection device uses ultrasonic welding between parts at the time of final connection, which requires additional manufacturing equipment for ultrasonic welding. Difficulty in making simultaneous fabrication of ultrasonic welding conditions

[0011] In addition, the existing blood collection device prints the mark of the puncture depth adjustment stage of the lancet needle, so there are problems of delay in the production process and increase in cost due to defects such as printing drop-off, printing diffusion, and defects in the printing process.
