2. Description of the Related Art As is well known, a rubber stopper is fitted into an opening of a container for storing blood, such as a vacuum blood collection tube, for the purpose of preventing blood from flowing out.

By the way, this rubber stopper is removed, for example, when setting a blood collection tube to an automatic analyzer.
At present, the operation of removing the rubber plug is conventionally performed manually.

[0004] However, when the operation of removing the rubber stopper is performed manually, there is a possibility that the blood sample is touched and infected with various diseases, and the operation of removing the rubber stopper is performed on a large number of blood collection tubes. Therefore, there is a problem that such work is very complicated, and there is a risk of blood contact infection when collecting the collected rubber stoppers.

[0005] For this reason, the applicant first removes the rubber stoppers of a plurality of blood collection tubes by one operation without touching them, and collects and discards the removed rubber stoppers without shaking hands. A device for opening a blood collection tube or the like that has a simple configuration is proposed (Japanese Utility Model Application No. 3-40444).

An apparatus for opening a blood collection tube or the like according to the earlier application of the present applicant includes a base member, a support erected on the base member, and a rotatably pivoted support above the support. A rotating member, a locking piece connected to a front edge of the rotating member, and a blood collection tube or the like pulled out by the locking piece by rotating the rotating member. A stopper pad for dropping and storing the attached rubber wire.

This invention has been made for the purpose of greatly reducing the opening operation force in the opening apparatus for blood collection tubes and the like according to the earlier application of the present applicant.

[0008]

In order to achieve the above object, according to the present invention, an apparatus for opening a blood collection tube or the like is provided with a base member, a supporter erected on the base member, and a supporter. A rotating member rotatably supported on the upper part of the body,
The rotating member includes a locking piece connected to a front edge of the rotating member, and a handle attached to the rotating member. It is characterized by being mounted obliquely in the direction of rotation of the member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in the accompanying drawings.

As shown in FIGS. 1 and 2, an opening device 1 according to this embodiment has a flat base member 2 having a rubber mat 3 adhered to a lower surface thereof, and a front side of the base member 2. A pair of supports 4, 5 erected at both ends, a rotating member 7 rotatably supported on the upper portions of the supports 4, 5 via a shaft 6, And a plug receiving pad 8 detachably mounted on the upper surface.

The base member 2 has a space for accommodating a rack 15 on which blood collection tubes 14 and the like are erected, on the front side of the portion where the supports 4 and 5 are erected.
The blood collection tube 14 and the rack 15 are set in the space from the direction indicated by the arrow A in FIG. 1, or are set by sliding from the lateral direction B of the base member 2 as shown in FIG. Reference numeral 18 in the drawing indicates a stopper piece attached to the front end of the base member 2. The stopper piece 18 moves when the rack 15 is set at a predetermined opening position. It functions so as not to rotate in the direction 1b, so that the opening operation can be performed stably.

The rotating member 7 includes a horizontal plate portion 10, a locking piece portion 11 extending downward from a front edge of the horizontal plate portion 10 and having a substantially rectangular cross section. The horizontal plate 1
Support piece 12 extending downward from both ends on the depth side
And a handle 13 fixed to the upper surface of the horizontal plate portion 10;
And the shaft 6 is supported by each of the support pieces 12.
It is mounted below.

The turning member 7 stops in a state shown by a solid line in FIG. 1, that is, when the horizontal plate portion 10 is stopped in a horizontal state, and is not rotated counterclockwise from the horizontal state. (Not shown). Of course, the clockwise rotation in FIG. 1 is not restricted. The stopper body was formed by processing the shaft 6, and a projection (not shown) was formed on the shaft insertion hole side of the supports 4 and 5, so that the rotating member 7 was in a horizontal state. At this time, the processed portion of the shaft 6 can be configured to engage with a projection formed on the shaft insertion hole side of the supports 4 and 5 to maintain a horizontal state. A projection (not shown) is provided on the side of the horizontal plate portion 5 so that the lower surface of the horizontal plate portion 10 comes into contact with the projections formed on the support members 4 and 5 when the rotating member 7 is in a horizontal state. In addition, it may be configured to maintain a horizontal state.

When the rotating member 7 is set in the horizontal state, the locking end 11a is
Rubber stopper 16 fitted in an opening of blood collection tube 14 or the like in a liquid-tight manner
Is configured to be locked to the step 16a. It is desirable that the locking piece 11 be formed to have a rigidity that does not significantly bend and deform.

On the other hand, the handle 13 fixed to the upper surface of the horizontal plate portion 10 is attached such that the gripping piece 13a is inclined in the direction of rotation of the rotating member 7, that is, in the direction of FIG. 1a. The angle of inclination of the handle piece portion 13a is about 20 degrees in the illustrated embodiment. However, when the number of pieces to be pulled out at one time is large, the angle is made large. When the number of pieces is small, the inclination angle is made small. No problem.

By inclining the gripping portion 13a of the handle 13 in the rotating direction a of the rotating member 7 in this manner, the rotating operation force of the rotating member 7 at the time of opening the stopper is reduced, so that the gripping portion is vertically moved. It can be greatly reduced as compared with the case where it is mounted upright.

The plug receiving pad 8 has a substantially concave cross section and a substantially convex planar shape, and has a length dimension such that the rear end 8a is fixed to both sides of the rear end of the base member 2a. The front end 8b is formed so as to be flush with the front ends of the supports 4 and 5 so as to be flush with the corner fitting 17.

The plug receiving pad 8 has a front plate 8
When the locking piece 11 is engaged with the step 16a of the rubber plug 16 and is rotated about the shaft 6 as a fulcrum, the rubber plug 16 is pulled out. The pulled-out rubber plug 16 falls under its own weight in the direction of the plug receiving pad 8, rolls on the inclined surface of the front plate 8 c, and is stored in the plug receiving pad 8. Of course, the plug receiving pad 8 is not limited to the shape of the illustrated embodiment, but the rubber plug 16 pulled out by the locking piece 11.
Any shape can be used as long as it can be securely stored.

Next, a case where the rubber stoppers 16 of a plurality of blood collection tubes 14 held in the rack 15 are simultaneously removed by using the above-described opening device 1 will be described.

First, the rotating member 7 is set in a horizontal state, and the rack 15 holding the blood collection tube 14 is set at a predetermined position by the above procedure.

In this state, when the grip 13 is gripped with one hand and the rotating member 7 is rotated in the rearward direction of the base member 2 about the shaft 6 as a fulcrum, the engagement of the locking piece 11 is increased. After the toe 11a is engaged with the step 16a of the rubber plug 16,
The rubber plug 16 pulled out obliquely upward and thus pulled out from the blood collection tube 14 falls by its own weight toward the plug receiving pad 8 and is stored in the plug receiving pad 8.
At this time, since the grip 13 is attached to the handle 13 with the gripping piece 13a inclined in the rotation direction a of the rotation member 7, the rubber stopper 16 can be pulled out with a small operation force.

[0022]

As described above, according to the device for opening a blood collection tube or the like according to the present invention, the rubber stopper of the blood collection tube can be removed from the blood collection tube or the like with very light operation force without touching the rubber stopper of the blood collection tube. It has an excellent effect that it can be removed and there is no fear of blood contact infection.
