Definitions
- the present invention relates to a blood collection device used for puncturing the skin and collecting a small amount of blood, and more particularly to a disposable blood collection device discarded after one use.
- SMBG blood self-measurement
- this blood collection instrument generally includes a lancet and a spring having a sharp puncture body such as a puncture needle and a blade.
- the member is housed in a housing having an opening that opens to the outside.
- the lancet is urged by the spring member, and the tip of the puncture body projects from the opening of the housing to perform the puncture operation.
- the skin surface pressed against the opening of the housing can be punctured by the puncture body so that a small amount of blood can be exuded.
- the blood amount is insufficient for checking the blood sugar level, for example. If it is determined, the peripheral part of the part to be punctured may be pressed again against the peripheral part of the opening of the housing to perform an operation of further exuding blood. However, at that time, if the housing touches the blood on the surface of the skin that has become ball-shaped due to surface tension, the shape of the blood ball collapses and spreads, and therefore, predetermined tests and measurements such as checking the blood sugar level are performed. Often there were situations where it was impossible.
- the present invention has been made in the background of the above-mentioned circumstances, and the problem to be solved is to determine whether or not the amount of blood exuded on the skin surface by the puncture operation is sufficient. It is an object of the present invention to provide a disposable blood collection device that can be confirmed without being pulled away from the body and thereby can stably secure a sufficient blood volume with a single puncture operation.
- a lancet having a sharp puncture body at the tip and a spring member are accommodated in the housing, and the lancet is biased by the spring member so that the tip of the puncture body is
- a disposable blood collection device that protrudes from an opening of a housing and performs a puncture operation, and after the puncture operation, the distal end of the puncture body is retracted to a retracted position into the housing.

It is characterized in that it is located on the backward direction side.
- the puncture site when the puncture operation is performed with the skin surface pressed against the opening of the housing from the peripheral portion of the opening of the housing being the visible portion, The puncture site can be visually confirmed. Therefore, the amount of blood exuded from the puncture site on the skin surface can be confirmed without separating the housing from the skin surface. Moreover, when the puncture site on the skin surface is visually recognized through the visible portion from the housing position of the spring member in the housing, the spring member does not obstruct the puncture site. .
- the disposable blood collection device Accordingly, it is possible to advantageously increase the amount of collected blood while stably maintaining the shape of the blood ball. As a result, after one puncture operation, it is possible to reliably perform a predetermined test and measurement such as a blood glucose level check.
- the lancet when the lancet is arranged in a standby position in which the tip of the puncture body is accommodated in the housing in a state where the lancet is biased in the protruding direction of the puncture body by the spring member.
- a latching means for holding the lancet in the standby position against the biasing force of the spring member is provided between the lancet and the housing, and the latching means moves to the standby position. It is also possible to adopt a mode in which an unlocking means for releasing the holding of the lancet by an operation from the outside of the housing is provided.
- the user in the puncture operation, can perform the puncture operation by simply operating the unlocking means without requiring a troublesome work such as compressing the spring member. Can be done. Thereby, the blood self-collecting operation can be more easily performed.
- the tip portion that is the free end in the lancet is A flexible arm that is bent and deformable in a direction approaching the outer peripheral surface of the lancet is projected, and the flexible arm is locked when the lancet is arranged at the standby position.
- a stop portion is provided on the housing, and the locking means is configured to include the flexible arm and the locking portion.
- the distal end portion of the flexible arm is attached to the lancet by an external operation.
- the flexible arm as the locking means for realizing the holding of the lancet at the standby position with an excellent locking operation and an easy releasing operation.
- the outer peripheral size of the housing can be made small and compact.
- the locking means includes a flexible arm and a locking portion
- the flexible arm moves from the front side to the rear side in the protruding direction of the puncture body along the lancet.
- An operating portion that is projected so as to extend and is locked to the locking portion at an intermediate portion in the extending direction of the flexible arm, while an operation from the outside is performed in the locking releasing means,
- locking part of this flexible arm is employ
- the locking release means moves to the flexible arm. Contact is avoided. Therefore, when the lancet moves in the housing in the protruding direction of the puncture body from the opening of the housing, the puncture output of the puncture body from the housing opening may be reduced due to interference with the lancet of the unlocking means. It can be effectively avoided.
- the operation portion for the locking release means is provided on the distal end side of the flexible arm, the flexible arm can be bent with a small operating force to release the locking of the flexible arm. .
