Abstract

PURPOSE:To enable efficient gathering of blood by freely bending a gasket mounted on a plunger in the direction of the rear end at the time of moving the plunger. CONSTITUTION:Before use, a spring 3 is in the open state, and a projecting part 13 of a plunger 2 is locked at the rear end 14 of a housing 1. At the time of use, the plunger 2 is advanced while compressing the spring until it collides with a plunger stop part 7 of a forward end cap by pressing a push plate 6 of the rear end of the plunger 2. Subsequently, after the forward end opening part 5 of a tool is pressed to the skin where a piercing needle is stuck, the force of the push plate 6 is released to move the plunger 2 backward, so that blood is sucked out by negative pressure generated in the housing. After that, the plunger 2 is advanced and a gasket 4 is bent in the direction of the rear end to force the atmospheric pressure to enter the housing 1, whereby the pressure reducing condition is canceled.

2. Description of the Related Art A lancet syringe generally comprises a cutting edge having a sharp tip and a pressing portion on the opposite side for puncturing the skin of a human body, and the cutting edge is tapped to tap the cutting edge. Is punctured by the skin of a human body, for example, a finger, and a small amount of blood flowing out from the punctured site is collected by a pipette or a capillary tube and used for various blood tests. However, since blood vessels are concentrated in the finger, small droplets of blood can be squeezed out, but since considerable pain is concentrated in the finger, it is necessary to puncture the upper arm, abdomen, thigh, etc. with a lancet syringe in recent years. A method of collecting a large amount of blood is used. For example, in JP-A-62-38140, after puncturing the skin with a lancet support having a gasket that slidably slides in the tube, the negative pressure generated in the tube when the support returns due to the spring force is applied. There has been proposed a blood sampling device that draws blood by utilizing it.

However, since this device automatically locks the lancet support in the state where the skin is pulled by the negative pressure after puncturing the skin, the tip of the tube is kept in the state where the skin is in the negative pressure. When is separated from the skin, there is a drawback that extra blood volume must be collected because blood droplets are scattered around due to the rapid restoration of the pulled skin and the entry of outside air into the tube. An object of the blood suction device of the present invention is to provide a blood suction device for sucking out a punctured blood in a necessary amount, eliminating negative pressure during blood suction, and collecting blood without scattering.

Operation: By pushing the plunger in the direction of the tip, the tip of the plunger moves forward and the tip of the plunger moves.
It abuts the stop and at the same time the spring is compressed. Then, after pressing the opening of the tip of the liquid medicine injecting device against the skin punctured by a puncture needle or the like, the spring compressed by releasing the force of the plunger pushed forward by the finger is released and the plunger is released. Moves backwards. As a result, the inner chamber of the housing between the opening and the gasket, which has been in close contact with the skin, is in a depressurized state, and blood can be sucked out from the place where the skin is punctured. When the blood volume required for blood test is reached while observing with the transparent tube at the tip of the housing, pushing the plunger forward creates a gap between the gasket and the inner wall of the housing, and the air flows into the inner chamber of the housing. , The inner chamber of the housing, which was in a depressurized state, becomes normal pressure,
Blood can be collected without scattering.

The operation procedure of the blood suction device of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a cross-sectional view showing the state of the blood suction device before use. The spring 2 is opened and the plunger 2 is moved backward until the ridge 13 of the plunger 2 is locked at the rear end 14 of the housing 1. It is arranged. Then, by pushing the push plate 6 at the rear end of the plunger-2 forward with a finger, the tip of the plunger-2 is attached to the tip cap 9 as shown in FIG.
It moves forward until it abuts against the plunger stop 7 formed at the rear end, and at the same time the spring 3 is compressed. Next, the pressing plate 6 of the plunger-2, which was pressed by the finger after pressing the tip opening 5 of the drug solution injector against the skin punctured by the puncture needle or the like
The spring 3 which has been compressed by releasing the force is released and the plunger-2 moves rearward. As a result, the inner chamber of the housing between the distal end opening 5 and the gasket 4, which was in close contact with the skin, is in a decompressed state, and blood can be sucked out from the place where the skin is punctured. Plunger-2
The force of the push plate 6 is gradually released while observing with the transparent tube of the tip cap 9, and when the blood amount necessary for the blood test is reached, the plunger 2 is pushed forward to move the gasket 4 and the housing 1. A space is formed between the inner wall of the housing and the atmosphere, and the air flows into the housing inner chamber 11, the housing inner chamber 11 that has been in a decompressed state becomes normal pressure, and blood can be collected without being scattered.
