Abstract
The utility model belongs to medical equipment, particularly relates to a blood sampling device. A blood sampler comprises a sampler pipe (1), a sampler rod (2), a spring (3) and a fixer (4). An elastic protrusion (6) is arranged on the middle portion of the sampler rod (2). A locating groove which contains the elastic protrusion (6) is arranged on the inner wall of the sampler pipe (1). After the sampler rod (2) tightly presses the spring (3) by moving from a static position into the sampler pipe (1), the elastic protrusion (6) falls into the locating groove so that the sampler rod (2) rests on a ready position. The locating groove is provided with a blood sampling button (5). When the blood sampling button (5) is pressed to the right position, the elastic protrusion (6) is separated from the locating groove, and the spring (3) pushes the sampler rod (2) to move to a forefront position and then pulls the sampler rod (2) back to the static position. The blood sampler is reasonable in structure. Adjustable elasticity is achieved through the spring, and accordingly the depth of the blood sampler penetrating into skin can be adjusted, and aching feeling is greatly lowered.
Description
Technical field
This utility model belongs to a kind of medical equipment, particularly a kind of blood-taking device.
Background technology
Existing blood collecting pen is the vacuum blood collection pen, and its operation principle is to keep certain air pressure in pen, utilizes atmospheric pressure to eject blood taking needle.The shortcoming of this blood collecting pen is, elastic force is single, can't regulate the degree of depth of thrusting skin, and pain is obvious during use; The long-time elastic force that uses diminishes.
The utility model content
The purpose of this utility model is: a kind of blood collecting pen that can regulate elastic force is provided, overcomes the technological deficiency of vacuum blood collection pen, substantially reach painless blood sampling.
The technical solution of the utility model is: a kind of blood collecting pen, and it comprises: the shaft of a writing brush, the penholder of the described shaft of a writing brush of partial insertion inside is installed in the spring that the described shaft of a writing brush is interior, connect described penholder one end, is installed in the needle head fixer of the described penholder other end; The middle part of described penholder is provided with elastic bumps, described shaft of a writing brush inwall is provided with the locating slot that holds described elastic bumps, when described penholder began to move the described spring of compression in the described shaft of a writing brush from resting position after, described elastic bumps fell into described locating slot, makes described penholder rest on cocked orientation; Described locating slot is provided with the blood sampling button, when described blood sampling button be pressed put in place after, described elastic bumps breaks away from described locating slot, described spring promotes described penholder and moves to the forefront position, more described penholder is withdrawn into resting position.
This utility model realizes that by adjusting spring elastic force is adjustable, thereby can regulate the degree of depth that blood collection needles is thrust skin, and pain is reduced greatly, has substantially realized painless blood sampling.
