[Industrial applications]

 The present invention relates to a rubber stopper opening device capable of removing a rubber stopper fitted to an opening of a blood collection tube without touching the same, and particularly effective for scattering blood when opening the stopper. The present invention relates to a cap opening device that can be prevented.

[0002]

[Prior art and its problems]

 As is well known, a rubber container such as a vacuum blood collection tube is generally fitted with a rubber stopper at its opening for the purpose of preventing blood from flowing out.

By the way, this rubber stopper is detached and set in the automatic analyzer when the blood collection tube is set in the automatic analyzer, for example. The current situation is that it is done manually.

However, when the rubber stopper is manually removed, there is a risk that various diseases will be infected by contact with the collected blood, and the manual removal of the rubber stopper is Since it is performed on a large number of blood collection tubes, there is a problem that such work is very complicated.

Therefore, the present applicant has previously proposed a blood collection tube opening device having a simple structure that allows the rubber stoppers of a plurality of blood collection tubes to be pulled out without touching the hands ( Practical application No. 3-40444).

[0006] The capping device for a blood collection tube according to the earlier application of the applicant is a base member, a support member erected on the base member, and a pivotally rotatably supported on an upper portion of the support member. The rotating member, the locking member connected to the front edge of the rotating member, and the rotating member, which is attached to the blood collection tube pulled out by the locking piece, by rotating the rotating member. It is composed of a plug receiving pad for dropping and storing the rubber plug.

By the way, since the rubber stopper fitted into the blood collection tube is mainly made of raw rubber material, when the rubber stopper is pulled out by the blood collection tube opening device according to the applicant's earlier application, Due to the restoring force of the rubber stopper, the blood attached to the rubber stopper is scattered and adheres to the human body, which may cause blood infection.

The present invention has been made in view of the present situation, and an object thereof is to prevent the scattering of blood at the time of opening the stopper by the double action of the rotating member to restore the rubber stopper. The purpose of the present invention is to provide an opening device that can surely prevent blood scattering due to force.

【Example】

 Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the accompanying drawings.

As shown in FIG. 1, a cap opening device 1 according to this embodiment has a flat plate-shaped base member 2 having a rubber mat 3 adhered to the lower surface, and both front end portions of the base member 2. On the upper surface of the base member 2, there are provided a pair of upright supporting members 4, 5, a rotating member 7 which is rotatably supported on the upper portions of the supporting members 4, 5 via a shaft 6. It comprises a rubber plug storage container 8 which is detachably attached, and a stopper member 18 which is normally urged in a direction to make elastic contact with the supports 4 and 5.

The base member 2 is configured to have a space for accommodating a rack 15 in which a plurality of blood collection tubes 14 are erected and held, on the front side of the portion where the supports 4 and 5 are erected. On the upper surface of the front edge portion of the base member 2 forming the space, a convex projection 2a is projected along the longitudinal direction (the same direction as the transport direction of the rack 15. The same applies below). It is set up. Of course, in this embodiment, the blood collection tube 14 and the rack 15 are set in the space from the front side of FIG.

A stopper member 18 is rotatably supported by a rear end portion of the supports 4 and 5 via a shaft 19, and the stopper member 18 is in a normal state via a spring member 20. It is urged in the direction in which it abuts against the rear end portions of the supports 4, 5.

Further, a substantially J-shaped void portion 21 is formed at the upper end of the stopper body 18, and when the rotating member 7 is rotated from the horizontal state in the opening direction, the rotation will be described later. The supporting piece portion 12 of the moving member 7 is configured so as not to collide with the upper end portion of the stopper body 18 within the space 21.

An inverted concave groove 15a for fitting and locking the projection 2a is formed on the lower surface of the rack 15 along the longitudinal direction thereof.

The rotating member 7 includes a horizontal plate portion 10 and a locking piece portion 11 extending downward from a front edge portion of the horizontal plate portion 10 and having a substantially L-shaped cross section. The shaft 6 includes a support piece 12 extending downward from both ends of the horizontal plate 10 on the depth side, and a handle 13 fixed to an upper surface of the horizontal plate 10. It is mounted below the support piece 12.

Further, the rotating member 7 stops in a state shown by a solid line in FIG. 1, that is, when the horizontal plate portion 10 is in a horizontal state and stops from rotating in the counterclockwise direction in FIG. 1 from the horizontal state. It is regulated by a lid body (not shown) and is rotatable in the clockwise direction in FIG.

That is, in the state where the rear end of the support piece 12 does not collide with the upper end of the stopper body 18, the rotating member 7 has a light operating force within the range of the void 21 shown by the phantom line in FIG. Then, when the rotating member 7 further rotates in the clockwise direction in FIG. 1, the supporting piece 12 resists the urging force of the spring member 21. Then, the rubber stopper 16 is pulled out by rotating together with the stopper body 18. At this time, the turning operation force of the turning member 7 becomes slightly heavier than that when the support piece 12 is turning within the range of the gap 21.

The stopper body is formed by processing the shaft 6, and a protrusion (not shown) is formed on the shaft insertion hole side of the support bodies 4 and 5 so that the rotating member 7 is in a horizontal state. Then, the processed portion of the shaft 6 can be configured to engage with the protrusion formed on the shaft insertion hole side of the supports 4 and 5 to maintain the horizontal state, or the above support When a protrusion (not shown) is provided on the side of the bodies 4 and 5 and the rotating member 7 is in a horizontal state, the lower surface of the horizontal flat plate portion 10 is formed on the supports 4 and 5. It can also be configured to abut the protrusion to maintain the horizontal state.

The locking piece 11 is a rubber stopper in which the locking end 11 a of the locking member 11 is fitted in the opening of the blood collection tube 14 in a liquid-tight manner when the rotating member 7 is set in the horizontal state. It is configured to be locked to 16 step portions 16 a.

On the other hand, the handle portion of the handle 13 fixed to the upper surface of the horizontal plate portion 10 is attached so as to be inclined in the rotating direction of the rotating member 7, that is, the direction shown in FIG. 1a. Although the tilt angle of the handle portion is set to 20 degrees in the illustrated embodiment, the longitudinal direction of the rack 15 is set to the direction orthogonal to the human body to open the cap. Depending on the rotating operation direction of the rotating member 7, the rotating member 7 may be further inclined so that the rotating operation can be performed with a light operation force.

The rubber plug storage container 8 is formed to have a substantially concave cross section and a substantially planar planar shape. The length dimension of the rubber plug storage container 8 is such that the rear end portion 8 a is fixed to both sides of the rear end portion of the base member 2. The corner metal fitting 17 is positioned in abutment with the metal fitting 17, and its front end portion 8b is formed to have a length dimension that is flush with the front end portions of the supports 4 and 5.

Further, the rubber plug storage container 8 has a front plate 8 c formed to be inclined, and the locking piece portion 11 engages with the step portion 16 a of the rubber plug 16 to allow the shaft 6 to move. When the rubber plug 16 is pulled out by being rotated around the fulcrum as a fulcrum, the pulled rubber plug 16 falls by its own weight toward the rubber plug storage container 8 and rolls on the inclined surface of the front plate 8c. Then, the rubber stopper storage container 8 is configured to be stored. Of course, the rubber plug storage container 8 is not limited to the illustrated embodiment, and may have any suitable shape as long as the rubber plug 16 pulled out by the locking piece portion 11 is securely stored. Can be used.

Therefore, in the cap opening device according to the above-described embodiment, when the rotating member 7 is rotated to pull out the rubber stopper 16 from the blood collection tube 14, first, the rotating member 7 is removed. When the rubber stopper 16 is rotated from the horizontal state within the range of the void 21 shown by the phantom line in FIG. 1 and collides with the upper end of the stopper body 18, the rotation operation is stopped and the rubber stopper 16 is attached to the blood collection tube. Pull out slightly from the top of 14.

Thereafter, the rotating member 7 is rotated counterclockwise in FIG. 1 to return to the horizontal state. As a result, the rubber stopper 16 is released from the extended state by the pulling work and contracts and restores due to the restoring force. Therefore, when the rotating member 7 is further rotated in the clockwise direction in FIG. When the piece portion 12 again abuts against the upper end portion of the stopper body 18 and the rotating member 7 is further rotated in the clockwise direction in FIG. 1 from this state, the rotating member 7 resists the biasing force of the spring member 21 and the rotating member 7 rotates. The member 7 rotates together with the stopper body 18, and the rubber stopper 16 is pulled out from the blood collection tube 14 in association therewith, and blood scattering due to the restoring force of the rubber stopper 16 can be reliably and effectively prevented. .
