Description

  The present invention relates to a fixture for fixing a tourniquet used in blood collection or the like.

  Conventionally, when a vein is punctured in blood collection or intravenous injection, a tourniquet is used to compress the vein to make it angry and facilitate puncture. Known tourniquets are one in which a rubber tube is directly wound around an arm, and one in which one end portion has a holding scissors-like holding portion and the other end portion can be held and fixed.

In general, since the tourniquet needs to be removed immediately before blood collection is completed, it is required to remove the tourniquet with the other hand while holding the syringe with one hand.
However, for example, the technique described in Patent Document 1 has a problem in that it has a fastener and cannot be easily removed with one hand. Such a problem is a problem common to conventional tourniquets.
Utility Model Registration No. 3150237

  The present invention is to solve the conventional problems as described above, and an object of the present invention is to provide a tourniquet fixing device that can be easily removed with one hand in blood collection or the like.

  In order to solve the above-mentioned problem, in the device according to claim 1, in the tourniquet fixing device capable of fixing the tourniquet that is wound around the arm and presses the veins of the arm to anger, There is a locking portion provided with a hole through which one end of the tourniquet can be inserted and fixed, and a clamping portion connected to the locking portion and capable of clamping and fixing the other end of the tourniquet. It is characterized by that.

An anger means that the blood vessel swells more than usual. At the time of blood collection, it can be performed by causing blood to flow into the peripheral side by compressing venous blood and expanding the blood vessel on the peripheral side.
Therefore, when the one end portion of the tourniquet is inserted and fixed in the hole, the tourniquet is wound around the arm, and the other end portion of the tourniquet is sandwiched between the sandwiching portions. The tourniquet is fixed to the arm, and the veins of the arm are compressed and angry. In addition, when the other end portion of the tourniquet is opened from the clamping portion, the tourniquet is released from a state of being wound around the arm.

  In the device according to claim 2, the sandwiching portion includes a base frame portion and a link structure provided in the base frame portion, and the link structure includes a first fixed joint portion, A second fixed joint portion provided apart from the first fixed joint portion, a drive link portion having one end portion rotatably attached to the first fixed joint portion, and one end portion being the second fixed joint portion A driven link portion rotatably attached to the drive link portion, and a connecting link portion connecting the other end portion of the drive link portion and the other end portion of the driven link portion, wherein the drive link portion is rotated. In this case, the driven link portion is rotated via the connecting link portion, and the tourniquet is configured to be sandwiched and fixed between the driven link portion and the base frame portion. Features.

  Therefore, when the drive link portion is rotated, the driven link portion is rotated via the connection link portion, and the tourniquet zone is interposed between the driven link portion and the base frame portion. The other end is clamped and fixed.

  4. The device according to claim 3, wherein the base frame portion is formed by extending a base frame main body portion to which the first fixed joint portion is attached and the base frame main body portion. It has the 1st arm part to which the joint part was attached, and the 2nd arm part extended from the said 1st arm part and bent and formed, It is characterized by the above-mentioned.

  Therefore, when the drive link portion rotates, the driven link portion rotates with respect to the first arm portion via the connection link portion, and the driven link portion and the second arm portion In the meantime, the other end portion of the tourniquet is clamped and fixed.

  In the invention according to claim 4, an operation unit is provided in the drive link unit, and when the operation unit is fixedly operated, the driven link unit is connected to the second link via the connection link unit. While rotating to approach the arm portion, the other end portion of the tourniquet is sandwiched between the second arm portion, and when the operation portion is opened, the driven link portion is It rotates so that it may space apart from said 2nd arm part via a connection link part, The other end part of the said tourniquet is released from between said 2nd arm parts.

  Therefore, when the operation unit is fixedly operated, the driven link unit rotates so as to approach the second arm unit via the connection link unit, and the other end portion of the tourniquet is While being held between the second arm portion and the operation portion being opened, the follower link portion is rotated so as to be separated from the second arm portion via the connection link portion. Then, the other end portion of the tourniquet is released from the space between the second arm portion.

  In the device according to claim 5, the base frame part is formed to be curved as a whole, and when the tourniquet is wound around the arm, the base frame part extends along the arm. It is mounted.

  Accordingly, when the tourniquet is wound around the arm, the base frame portion is attached along the arm.

  The device according to claim 6 is characterized in that the tourniquet is made of rubber.

In the tourniquet fixing device according to claim 1, the one end portion of the tourniquet is inserted and fixed in the hole, and the tourniquet is wound around the arm and the tourniquet is performed. When the other end of the band is clamped by the clamping unit, the tourniquet is fixed to the arm, and the veins of the arm are angry, while the other end of the tourniquet from the clamping unit. When the part is opened, the tourniquet is released from the state of being wound around the arm, so that the tourniquet can be attached / detached only by operating the holding part.
As a result, it is possible to provide a tourniquet fixing tool that can be easily removed with one hand during blood collection or the like.

  In the tourniquet fixing device according to any one of claims 2 to 4, when the drive link portion rotates, the driven link portion rotates via the connection link portion, and the driven link Since the other end portion of the tourniquet is clamped and fixed between the base frame portion and the base frame portion, the tourniquet can be performed without directly operating the sandwiching portion by rotating the drive link portion. The other end of the band can be fixed.

  Particularly, in the tourniquet fixing device according to claim 4, when the operation portion is fixed, the driven link portion approaches the second arm portion via the connection link portion. And the other end portion of the tourniquet is sandwiched between the second arm portion, and when the operation portion is opened, the follower link portion becomes the connection link. Since the other end portion of the tourniquet is released from the space between the second arm portion and the second arm portion, the operation portion is rotated. Thus, the other end portion of the tourniquet can be fixed and released without directly operating the clamping portion.

  6. The tourniquet fixing device according to claim 5, wherein when the tourniquet is wound around the arm, the base frame portion is attached along the arm. In the state where the belt is wound around the arm, it is possible to prevent the arm from being partially compressed by the base frame portion, and to maintain an appropriate blood vessel compression state by the tourniquet.

  In the tourniquet fixing device according to claim 6, since the tourniquet is made of rubber, the tourniquet is wound around the arm and the other end of the tourniquet is extended. When clamped in the clamping part in the state, the tourniquet pulls the driven link part constituting the clamping part to the base frame part side in the thickness direction by the restoring force of rubber, The rotational movement of the driven link portion can be restricted, and as a result, the tourniquet can be fixed securely.
