The inside of the casing 2 is divided into three chambers, that is, a first chamber 2A, a second chamber 2B, and a third chamber 2C, in order from the innermost side toward the opening 2a side by an annular partition, and the innermost portion is located at the innermost position. A small laser oscillator 3 is housed in the located first chamber 2A, and the laser beam L is emitted toward the opening 2a side. In the present embodiment, the laser oscillator 3 that emits a semiconductor laser having a wavelength of 0.6 μm to 1 μm is used as the laser oscillator 3.
The output of the laser beam L emitted from the laser oscillator 3 can be controlled by the control device 4. The laser oscillator 3 is turned on by projecting to the outside of the first chamber 2A.
The ON / OFF switch 5 can be operated when required. Next, in the second chamber 2B of the casing 2,
Conventionally known prism 7 via cylindrical spacers 6, 6.
The beam collimator 8 and the beam collimator 8 are overlapped with each other, and the condenser lens 9 is provided at the partition between the second chamber 2B and the third chamber 2C. As a result, the laser beam L emitted from the laser oscillator 3 is shaped by the prism 7 and the beam collimator 8 and then focused by the focusing lens 9 to form the opening 2 a of the casing 2.
It is designed to focus at the outer position. next,
A blood collection container 10 that stores blood is detachably fitted in the third chamber 2C on the side of the opening 2a of the casing 2. The blood collection container 10 has a negative pressure of a predetermined value, and at the negative pressure of the predetermined value, the mouth portion 1 of the blood collection container 10 has a negative pressure.
0a is sealed by a cap 11 (see FIG. 3). The blood collection container 10 is made of a material such as glass that allows the laser beam L to pass therethrough, and as shown in FIG. 1, when the bottom portion 10b is fitted to the deepest inside of the third chamber 2C, the mouth portion 10a is formed. Is projected outward from the opening 2a of the casing 2 by a predetermined dimension. The blood collection container 10 is sterilized inside before introducing negative pressure, and after sterilizing in this way, after introducing negative pressure into the blood collection container 10, it is sealed by the cap 11. ing. The cap 11 of this embodiment is
Made of rubber or synthetic resin, the thickness of the central part is
It is set thinner than the other parts. further,
In the present embodiment, the focal point of the laser beam L condensed by the condenser lens 9 is the mouth portion when the blood collection container 10 is fitted to the innermost position in the third chamber 2C as described above. The cap 11 attached to 10a is located at the center. Moreover, the output of the laser beam L is adjusted so that when the laser beam L is applied to the central portion of the cap 11, a hole can be easily formed in the central portion. With the above configuration, when collecting blood from the human body, the blood collection container 10 is provided with the bottom portion 10 thereof.
It fits in the 3rd chamber 2C until b is located in the deepest part of the 3rd chamber 2C. Thereby, the blood collection container 1
The mouth portion 10a of 0 comes to protrude from the opening portion 2a of the casing 2 by a predetermined amount and is held by the casing 2 in that state. Next, in that state, the blood collection container 1
The cap 11 of 0 is polymerized on a required position of the skin 12 which is a blood sampling site. Next, in this state, the switch 5 is pressed to operate the laser oscillator 3 for about 10 milliseconds, for example. As a result, the laser beam L is emitted from the laser oscillator 3, so that the laser beam L passes through the prism 7 and the beam collimator 8 to be shaped, and then is further condensed by the condenser lens 9 before being collected in the blood collection container. Bottom 1 of 10
The light passes through 0b and is irradiated to the central portion of the cap 11. As described above, since the central portion of the cap 11 is thin, when the laser beam L is applied to this central portion, a minute hole is opened in an instant. Almost at the same time, a minute hole is made by the laser beam L in the skin 12 and the blood vessel where the central portion of the cap 11 is superposed. At this time, since the blood collection container 10 has a negative pressure, the blood 13 is sucked into the blood collection container 10 through the minute holes formed in the blood vessel, the skin 12, and the cap 11, and is automatically stored. (See FIG. 2). When the blood 13 is stored in the blood collection container 10 and the pressure in the blood collection container 10 becomes substantially equal to the atmospheric pressure, the suction of the blood 13 into the blood collection container 10 naturally stops. Therefore, after this, the cap 11 is separated from the skin 12, and the casing 2 is supported so that the mouth portion 10a of the blood collection container 10 is vertically upward, and in that state, the blood collection container 10
Should be removed from the third chamber 2C of the casing 2. As a result, the blood collecting operation by the blood collecting device 1 is completed. According to the blood collecting device 1 of the present embodiment described above, blood can be collected without using an injection needle, so that it is possible to eliminate the possibility that the blood collecting subject will be infected with virus by the injection needle. Further, since it is not necessary to dispose of the injection needle after use, it is possible to simplify the operation at the time of blood collection as compared with the conventional general blood collection method using the injection needle. (Second Embodiment) Next, FIG. 4 shows a second embodiment of the present invention. In this second embodiment, the amount of blood that can be collected in the blood collection container 110 can be finely adjusted. The casing 102 is supported at a predetermined height. That is, the casing 102 is held at a predetermined height by a frame (not shown) with the opening 102a thereof facing vertically downward. On the lower side of the opening 102a, the ring-shaped Peltier element 116 and the ultrasonic sensor 117 are held at a predetermined height by the frame. The other structure is the same as that of the first embodiment. With such a structure, when collecting blood, the ultrasonic sensor 117 and the Peltier element 1 are attached to the outer peripheral portion of the blood collecting container 110 having the same structure as that of the above-described first embodiment on the bottom 110b side.
16 and is inserted into the third chamber 102C through the opening 102a. Thereby, the blood collection container 11
0 is held by the casing 102 with its mouth 110a facing vertically downward. In addition, the blood collection container 11
The outer periphery of the body portion of 0 is surrounded by the Peltier element 116 and the ultrasonic sensor 117. In this state, the skin 112 is covered with the cap 1
After being superposed on 11, the switch 105 is pressed for about 10 milliseconds to irradiate the cap 111 with the laser beam L. As a result, the cap 11 is provided in the same manner as in the first embodiment described above.
1. Since the skin 112 and the blood vessel have holes, the blood collection container 1
Blood 113 can be collected in 10. In this way, each blood collection container 110 is sequentially replaced and blood is collected therein. If it is desired to change the amount of blood 113 collected in the blood collection container 110, as shown in FIG. After fitting the container 110 into the third chamber 102C, the blood collection container 110 is heated or cooled by the Peltier element element 116 utilizing the conventionally known Peltier effect. By heating or cooling the blood collection container 110 in this manner, the negative pressure inside the blood collection container 110 can be adjusted, and the negative pressure inside the blood collection container 110 being adjusted can be detected by the ultrasonic sensor 117. When the negative pressure in the blood sampling container 110 detected by the ultrasonic sensor 117 reaches a predetermined value, heating or cooling of the blood sampling container 110 by the Peltier element element 116 is stopped. Thus blood collection container 110
After adjusting the negative pressure therein to a predetermined value, blood is collected in the blood collection container 110 as described above. Then, in the blood collection container 110 after the blood collection is completed, there is more (or less) blood than the blood collection amount in the blood collection container 110 in which the negative pressure is not adjusted, by the amount corresponding to the adjustment value of the negative pressure by the Peltier element element 116. Will be collected. Such a second
According to the embodiment, it is possible to obtain the same operational effect as in the case of the above-described first embodiment, and it is possible to adjust the blood collection amount. Further, according to the second embodiment, the blood collection container 1 is monitored by monitoring the fluctuation of the negative pressure in the blood collection container 10.
An airtight leak of 0 can also be detected. In the second embodiment, the negative pressure in the blood collection container 110 is adjusted to a predetermined value in advance before the blood collection into the blood collection container 110 is started, but the blood collection into the blood collection container 110 is started. During the subsequent blood collection, the value of the negative pressure in the blood collection container 110 may be finely adjusted by the Peltier element 116.
