Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sample container opening cutter and an opening device.
[0002]
[Prior art]
A clinical test sample such as blood is contained in a sample container and sealed with a film, a cap, or the like.
[0003]
As a conventional device for opening a sealed sample container, there is a device that can efficiently perform an opening process by eliminating a manual operation with a risk of secondary infection.
[0004]
That is, there has been a device in which a film portion of a stopper of a sample container (blood collection tube or the like) is punched out by a heated metal cutter and opened (for example, see Patent Document 1). Since the metal opening mechanism such as the cutter section is sterilized by heating at the same time, contamination (contamination) at the time of opening the next time can be prevented.
[0005]
However, in recent years, the accuracy of testing equipment has improved, and even trace amounts of residual serum that should have been heat-sterilized can be detected as the next sample, making it impossible to prevent contamination sufficiently. there were.
[0006]

[0007]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a sample container unsealing cutter and an unsealing device capable of suppressing contamination as compared with the related art.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the present invention employs the following technical means.
{Circle around (1)} The sample container opening cutter according to the present invention has a synthetic resin cutter portion for punching out and opening the stopper portion of the sample container (blood collection tube or the like), and is disposable each time a new sample container is opened. It is characterized by doing so.
[0009]
This sample container opening cutter has a synthetic resin cutter that punches out the sample container stopper and opens it. Those contaminated with serum etc. will not be used at the next opening.
[0010]
When a needle portion (needle-shaped portion) is provided inside the cutter portion, the plug can be prevented from dropping by holding the opened plug portion.
{Circle around (2)} An outer cylinder may be provided outside the synthetic resin cutter.
[0011]
With this configuration, the synthetic resin cutter for opening the sample container can be covered with the outer cylinder from the surroundings. Can be shielded. When the needle portion is provided inside the cutter portion, the needle portion can be covered with the outer cylindrical portion to prevent the needle portion from being broken before use, and also to prevent the needle portion from being punctured by the needle portion. it can.
[0012]
In addition, only the synthetic resin cutter part may be disposable, and the outer cylinder part may be repeatedly used as a separate body.
{Circle around (3)} A plurality of the synthetic resin cutters may be connected.
[0013]
With such a configuration, the unsealing operation can be performed uniformly by a plurality of (for example, ten) cutter units, so that the unsealing can be promptly performed.
(4) A slit may be formed between the plurality of synthetic resin cutter portions.
[0014]
With such a configuration, a plurality of synthetic resin cutter portions can be divided and used.
{Circle around (5)} The sample container opening apparatus is characterized in that the stopper portion of the sample container is punched out by the opening cutter and opened.
[0015]

【Example】
Next, the configuration of the present invention will be described more specifically.
(Example 1)
As shown in FIGS. 10 and 11, the sample container 1 opening device 9 is configured such that the stopper portion 21 of the sample container 1 is punched out and opened by the opening cutter 2 (see FIGS. 2 to 4) of the second embodiment. It is a handy type that processes one by one.
[0029]
Specifically, a release pin 10 and a ball plunger 11 are provided, and the operating section 12 is pushed (pressed) so that the opening cutter 2 can be detached and attached with one touch. Then, each time the sample container 1 is opened, the opening cutter 2 is disposable and replaced with a new opening cutter 2.
(Example 2)
As shown in FIG. 12, the opening device 9 of the sample container 1 is of a handy type in which the opening device 9 (see FIGS. 2 to 4) is processed one by one similarly to the first embodiment.
[0030]
Specifically, it includes a release pin 10, a spring 13, and an O-ring 14, and pushes (presses) the operation unit 12 to enable the detachment of the opening cutter 2 with one touch. Then, each time the sample container 1 is opened, the opening cutter 2 is disposable and replaced with a new opening cutter 2.
(Example 3)
As shown in FIGS. 13 and 14, the sample container 1 opening device 9 uses the opening cutter 2 of the third embodiment (see FIGS. 5 and 6) and operates the lever 15 to close the sample container 1. The part 21 is punched out 10 times at a time and opened.
(Example 4)
As shown in FIG. 15, the opening device 9 of the sample container 1 is of an automation type, and ten plugs 21 of the sample container 1 are simultaneously punched out by the opening cutter 2 (see FIGS. 5 and 6) of the third embodiment. I try to open it.
[0031]
First, ten opener cutters 2 stacked vertically on the stocker 16 are separated and supplied one by one by the pusher 17. The supplied opening cutter 2 is positioned and fixed by the stopper 18. Next, the chuck hand 20 is lowered by the vertically moving cylinder 19, and the opening cutter 2 is clamped and held at the lower end.
[0032]
The held opening cutter 2 is raised by the vertical movement cylinder 19, and is moved above the sample container 1 by the transfer robot 31. On the other hand, the ten sample containers 1 are conveyed by the conveyor 32 and disposed at a position corresponding to the opening cutter 2.
[0033]
The opening cutter 2 moved above the sample container 1 is lowered by the vertical movement cylinder 19, and at the same time as the lowering, the ten plug portions 21 of the sample container 1 are simultaneously punched out and opened. After opening, the opening cutter 2 is moved up again by the vertically moving cylinder 19. After ascending, the unsealing cutter 2 clamped and held by the chuck hand 20 is moved by the transfer robot 31 to a position right above the waste box 33. The chuck hand 20 is opened, and the opening cutter 2 is discharged into the waste box 33.
[0034]
On the other hand, the opened container sample 1 is carried out of the apparatus by the conveyor 32, the next unopened sample container 1 is transported and supplied, and the chuck hand 20 is again moved to the position of the new opening cutter 2 by the transport robot 31. . Thereafter, the above operation is repeated.
[0035]
【The invention's effect】
The present invention is configured as described above and has the following effects.
[0036]
Since the sample used at the previous opening and contaminated with serum or the like is not used at the next opening, it is possible to provide a sample container unsealing cutter and an unsealing device capable of suppressing contamination as compared with the related art.
