The present invention relates to a blood suction device set at a site to be punctured by a lancet.

リング装置が提案されている。2. Description of the Related Art For example, in order to easily measure a blood glucose level, a chip-shaped electrode sensor is inserted into an electrode insertion hole formed in a small, hand-held device main body, and is dropped on a skin using a lancet to collect blood droplets. 2. Description of the Related Art A simple measuring device is known in which a device is immersed, blood is sucked into a device main body by capillary action, and a measurement result is displayed on a display unit on the surface of the device main body. It has also been proposed that performing such a measurement at intervals of 10 to 15 minutes leads to the development of an artificial pancreas. It is easiest to perform such blood collection with the fingertips, and the required amount of blood is easily obtained.However, from the viewpoint of pain and the area when blood collection is repeated, the upper arm, abdomen, thighs, etc. Another way is to stab the lancet and squeeze the blood around the area to get the required droplets. At this time, in order to suppress pain and obtain a sufficient blood volume, a lancet support slidably supported in a tube and provided with a gasket around the tube is directed toward the skin according to Japanese Patent Application Laid-Open No. 62-38140. A blood sampling device has been proposed in which blood is aspirated by generating a negative pressure in a tube when the puncture is performed and then moved backward by a spring force.

The invasion of the outside air causes blood droplets to scatter around, and thus has the disadvantage of collecting more blood than is needed, and has the disadvantage of fouling the inside of the tube. Further, the forward movement speed of the needle when piercing with a lancet becomes slow due to friction against a tube wall of rubber or the like attached to the cylinder to maintain airtightness, thereby increasing pain at the time of skin puncturing. Furthermore, the structure is complicated, the production cost is high, and the needle replacement is troublesome because it is troublesome.

According to Japanese Patent Application No. 4-50443, in order to collect blood as small droplets on the skin, a transparent main body tube having an inner diameter larger than the outer diameter of the blood droplet to be collected is set at a site punctured with a lancet. Proposed a blood suction device with a suction device attached and a suction hole for sucking outside air into the main body pipe. In addition to this proposal, if the operation is somewhat troublesome, the blood suction device should be a syringe type without a suction hole in the main body tube, and the inner cylinder should be in the original position after the suction operation upward. It is also possible to return to. Thereby, the negative pressure at the time of suction is eliminated by opening the intake hole or returning the inner cylinder, and blood can be collected without scattering a wasteful amount according to the patient. In addition, by separating the lancet from the suction mechanism, the trouble of replacing the needle is reduced, and the speed of the needle during blood collection can be easily adjusted.

An object of the present invention is to increase a blood collection amount for a predetermined suction force in a blood suction device that performs blood collection by causing blood to be collected.

せ、次いで負圧を自動的に解消させる。When the blood suction device is manually operated, immediately after the lancet is stabbed into a portion other than the fingertip, the leading edge of the main tube is brought into contact with the skin so that the punctured portion occupies almost the center of the main tube. Then, the blood is sucked from the puncture site by suctioning with a suction device, and blood droplets are generated on the skin. Observation is made through the main body tube, and if necessary, the skin portion raised by suction is displaced inward by operating the skin squeezing device, that is, by displacing the surrounding area to be narrowed, thereby increasing the suction amount. After the generation of the droplets, the negative pressure for suction is released to return the pulled skin to the normal position, and the skin suction at the leading edge of the main body tube is released. When the blood suction device is always set and automatically operated, the blood suction device is set in advance at the puncture site of the lancet, and is set in advance after the operation of the suction device that was automatically operated at the time of puncturing the lancet. After a period of time, the skin wringer is automatically activated and then the vacuum is automatically released.

The flange portion 1c is set on the surrounding skin so that the puncture site occupies substantially the center of the main body tube 1 in a state where the puncture is closed with
Next, the rubber ball 2 is released. As a result, the elastic portion of the rubber ball 2 returns to the spherical shape, whereby the flange portion 1c is attracted to the skin, and a negative pressure is generated in the main body tube 1, and the skin raised from the surrounding skin as shown in FIG. 2B. As the raised portion 4 is formed, blood droplets 4a gradually begin to be generated due to the suction from the puncture site at the center thereof.

A small droplet 4a having a size required for the blood glucose meter described above, for example, a volume of about 2.5 to 5 μl, is easily collected. After blood collection, when the button 7a is pressed against the spring force to open the suction hole 3, outside air flows into the tube with a restricting action corresponding to the size of the suction hole, and the pulled skin is It returns to the normal position gently, and the suction of the flange portion 1c to the skin is released. As a result, there is no force to break the droplet 4a when the blood suction device 9 is detached, and therefore the droplet generated when the flange portion 1a adsorbed on the pulled skin is forcibly separated against the suction force. 4a is avoided.
