JPH0390862A - Chain holder with casings each for holding one tubular container - Google Patents

Abstract

PURPOSE: To make it possible to receive a tubular container which is variable in external diameter within a relatively large range by providing at least three elastic tongues in each casing. CONSTITUTION: In each easing 21a, at least three elastic tongues 31e and 41e are provided. Then, when a holder 3 does not contain a sample container 15 and the elastic tongues 31e and 41e are in a slack state, the distances of their free ends 31f and 41f from a shaft 9 are smaller than a half of the radius of the internal surfaces of rings 31a and 41a and, for example, approximately 40 to 45% of the radius. When the sample container 15 is inserted into the easing 21a, its radius is larger than the distances of the free end parts of the tongues 31e and 41e from the shaft 9 and all the tongues 31e and 41e grip the sample container 15 at least with their free end parts. The holder 3 can, therefore, receive the sample container 15 and hold it at a vertical position.

Description

DETAILED DESCRIPTION OF THE INVENTION Industry-E-Uses-Branch Field- The present invention has a casing for holding each tubular container, the casings pivoting about their axis. A chain-like chain which is freely interconnected and has an opening at its end into which a container can be inserted, and a pedestal for the container to be picked up at its lower end. This invention relates to a holding device.

This holding device serves for holding a tubular container. These containers serve in particular as sample containers or, briefly, as small sample tubes, each containing one sample to be analyzed, i.e. from a human or, if appropriate, an animal. containing body fluids such as serum, whole blood, urine, or spinal fluid;
Prior to analysis, it typically has an opening that is closed with a closure member such as a rubber elastic stopper. The chain-like holding device is
For carrying out the analysis, the transport means and/or supply means transport the analytical equipment as follows: the sample container held by the holding device with its vertical axis and opening upwards. can be guided and transported. The analytical equipment usually has at least one working station in which the syringe needle is inserted through the closure member and into the sample container L5, where the injection needle is inserted into the sample container. At least a portion of the body fluid contained in the specimen is aspirated from the sample container in order to carry out the analysis; Previous k,
There may be one working station for inserting the cannula into the socket I or into the closure member, so that the injection needle is then bounded by this cycad 1-. It penetrates through the passageway so that it can be inserted into the sample container.

The holding device may optionally be used instead of for the holding of the sample container or, in addition, of a tubular container containing the fluid solvent and/or fluid reagents required for the analysis. It is also useful for retention.

For tying them together, they have molded connecting means. This coupling means consists of a Z-curved arm and a second casing, which is open at both ends and is shorter than the first casing, which serves for receiving the sample container. The second cage receives the lower end portion of the first casing of the adjacent cage and is pivotally supported in rotation r1. The first casing has an outwardly projecting flange such that the first casing overlies the upper flange of the second casing of the adjacent retainer and the flange thereof In the middle k, the second casing is protruding.

The first casing has two diametrically opposed, outwardly projecting, arcuate casings J3 near its lower end.
It has several fixed ribs. The inner surface of the second casing has, at its lower end part k, a fixed enlargement. In the largest part of the cage, the jacket of the first cage is completely closed in the area of the fixing ribs, around the axis, and relatively narrow. -,! XM

-When the casings of the parts are connected by the cage,
From the L side, it is inserted into the second casing of the adjacent retainer so that it can be locked, but it is no longer possible to release the lock. Approximately every 10 retainers of the 6-chain retaining device k, the jacket 1 of the first casing has a U that surrounds each fixing rib at the bottom and on both sides. These sleeves l~ make it possible to release the fixing ribs of the holder in question again.

The one-piece body parts, which each form a first and second casing, are made of electrically insulating synthetic resin.

The tubular sample containers used for the analysis can have different volumes and external diameters, with the external diameter ranging between 91 and 16°5 mm, depending on the volume and the manufacturer. can fluctuate in

Known holding devices now have the disadvantage that certain holders are only able to receive sample containers whose outer diameter lies within a narrow range6, therefore, the body fluid The task of carrying out an analysis requires two different configured holder devices for sample containers having different outer diameters. This makes storage expensive, and when inserting the sample container,
It is necessary that a retaining device with a retainer corresponding to that diameter must be selected.

Furthermore, the known holding devices have the disadvantage that in order to separate two cages from each other, adjacent cages must be moved parallel to each other with respect to the axis of the casing. be. That is, when the holder to be separated already holds a sample container with a completely or partially open top containing body fluid,
During separation, there is a significant risk that body fluids will pour out of the sample container. It is also often disadvantageous that the chain-like holding device only makes it possible to separate the tenth holding device in each case.

When the analysis is carried out automatically, the analytical equipment must be able to detect a single sample during insertion of the syringe needle into the sample container and when the syringe needle is immersed in the fluid. must be confirmed.

When using known holding devices, this usually means that, in addition to the metal, electrically conductive needle, also several nail-like electrodes are inserted into the sample container. This is done by When the needle and the electrode reach the body fluid, this creates an electrically conductive connection between the needle and the electrode.6 In addition to the needle, the electrode is connected to the sample container. The requirement to have to be inserted inside is also a drawback.

5°C LnJl-cn Σ-M-decision, second knee-knee-knee-knee-ro-depart-departure G-The invention therefore provides that the drawbacks of known holding devices can be eliminated, In particular, the object is to provide a holding device capable of receiving a tubular container, the outer diameter of which can vary within a relatively large range.

The purpose is to obtain a chain-like holding device.

The invention additionally provides that the casing can be inserted into a sample container for trial use, easily and without the introduction of additional electrodes into the sample container held by the casing. It is an additional object to obtain a chain-like holding device that makes it possible to check by mechanical means when the syringe needle comes into contact with the body fluid contained in the sample container. .

In FIG. 1, a part of a chain-shaped retaining device 1 according to the invention is shown together with a retainer 3 and both ends, although it is noted that the number of retainers 3 can be varied within wide limits. ,
The retaining device 1 usually has an essential feature of k, which can be more than three in the illustrated retainer.
You should understand. Each cage 3 has a casing-like part 5
and a connecting means 7. These connecting means 7 are
Each cage 3, except for the cage 3 in the chain-shaped retaining device 1 at the right end in FIG. The holders 33 are connected with respect to each other in such a way that they can be pivoted about the vertical axis 9 of the casing-like part 5 when carrying out the analysis. Since the connecting means 7 of the holder 3 at the right end of the holder 1 are not used, they can optionally be cut off or omitted during manufacture. However, it should be understood that the holding device 1 can also be formed in an endless chain, ie a chain that is itself closed.

The casing-like part 5 of each cage 3 (one of which is shown separately in FIGS. 2 and 3) - bounds a generally cylindrical interior space 11; It also has an opening 13 at the upper end. During use of the holding device 1, a tubular container, ie a sample container containing the body fluid to be analyzed, can be inserted through the opening 13 in the middle of each casing-like part 5. A portion of one such sample container bearing the reference numeral 15 can be seen in FIG.

Each retainer 3 has an integral body 21. This main body 21 is made of a material based on a conductive synthetic resin, that is, a matrix made of an electrically insulating synthetic resin such as polyethylene, and carbon powder distributed within this matrix. That is, it is made up of graphite powder.

The inner surface 21d of the jacket l-21b is connected to the base 21c,
It has a slightly conical portion 21e enlarged upward, and this enlarged portion 21e includes a casing 21a.
A cylindrical enlarged portion 21r is connected within the region of the upper end. The enlarged portion 21f is bounded by a shoulder surface 21g in the radial direction, and the inner surface portion 21e has four holes 2111 distributed over its periphery and extending from the bottom to the top. , these lectures 21b
is the enlarged portion 2 communicating with the upper end k and the enlarged portion 21f.
1i. The enlarged portion 21r of the inner surface 21d is provided with an annular groove, which serves as a fixing recess 21,k. A protrusion 21m that protrudes inward is provided between the annular groove 21 of the enlarged portion 21 and the shoulder surface 21g.
This protrusion 21, +n consists of a semicircular cam when viewed from above. The generally cylindrical or slightly conical outer surface of the jacket J5 is provided with two annular rings 7i21n and 21p. Jackera 1 to 2To of the casing 21a is
, one notch 21q, which extends downward from the upper edge of the casing 21a to below the enlarged portion 21F, that is, at least the axial dimension of the casing 21a. It extends almost 2/3 of the way. The cut 21q makes the part of the jacket l-21b provided with the cut 21Q slightly elastic. The integrated main body 21 further includes two short arms 21r and 21s molded on the casing 21a, and a connecting member 211 or 21u held by them that has a C-shaped outline or a C-shaped profile. ing.

Then, the protrusion 21m of the casing 21a fits into the recess 31c of the ring 31a, thereby restricting the ring 31a from pivoting around the shaft 9. The ring 41a has on its outer upper k, lower edge annular ribs projecting outwards and serving as retaining projections 41e. In the assembled state, this ring 41a has an enlarged portion 2.
In the middle of the upper half of H, that is the ring 31 at the bottom.
The upper front surface thereof is approximately flush with the -E edge of the casing 21a. The fixing rib 4]c of the ring 41a is the assembly 4
1. When assembling the ring 41a, the retaining recess 21k is fitted into the retaining recess 21k.Therefore, this retaining recess 21k, together with the fixing rib 41c, provides a retaining means for freely retaining the ring 41a within the enlarged portion 21'. Ring 41g then holds ring 31a by itself.

Both assemblies 31.41 further include a row of elastic tongues 31c or 4 distributed on all sides of the shaft 9.

The four tongues 31e of the assembly 31 are all of the same length and have at least approximately 5 at the top k, also for example from the link 31a exactly straight and parallel to the axis 9. It has a part that projects downwardly and away, the length of which is equal to at least half the total length of the tongue 31a.

In addition, it is continuously curved, so that
The four tongues 41e of the 6 assembly 41 are of the same k and of the same length, such that the free lower end portion 31' of the tongue 3], e forms the point closest to its axis 9. however, the tongues 31e of the assembly 31 are shorter than the tongues 31e of the assembly 31.The tongues 41e, in their upper end portions, also have k, approximately parallel to the axis 9, holding them However, at least approximately k, already k

The inner surfaces of both rings 31a, 41a are connected to the casing 21
The narrower lower end of the slightly conical portion of the inner surface 21d of a has approximately the same diameter. The sample container used is otherwise, as usual, bounded by an arcuate bottom part which is approximately reduced downwards at the lower end. When the holder 3 does not contain any sample container and the elastic tongues 31, e, 41e are in their relaxed state, their free ends 31f
The distance from the axis 9 of rings 31a and 41f is
smaller than half the radius of the inner surface of 1a, e.g.
This radius has a value of approximately 40-45z.

When the sample container is inserted into the casing 21a, its radius is greater than the distance from the axis 9 of the free ends of the tongues 31e or 41e, and all the tongues are at least close to their free ends. Grasp the sample container by
Therefore, the holder 3 can receive a sample container,
It can be held in a vertical position and its outer diameter lies between half and the entire inner diameter of the rings 31a, 41a. The inner diameter of the rings 31a, 41a can be, for example, about 17m+m. At that time, the same retainer 3 will be approximately 9
3: to receive a sample container having an outer diameter lying between IIIl and 16.5-ring.

This configuration of the connecting means 7 makes it possible for the chain-like holding device 1 to separate each of the arbitrary holders 3, and for example to separate the individual holders 3 together with the sample container held thereby. Alternatively, it is also possible to remove a number of selected holders 3, each together with one sample container, from the holding device l. This possibility arises, for example, when the sample f1 contained in the sample container or in each of the sample containers in question is to be additionally subjected to a regular, automatically performable standard analysis. , or
This is very beneficial when instead k should be subjected to at least one special analysis. Otherwise, two or more retaining devices and/or one
It is also theoretically possible to connect the individual cages 3 to each other.

As already mentioned, the coupling means 7 can be engaged and disengaged by a movement perpendicular to the axis 9, thus horizontal. This means that the shaft 9, and therefore also the sample container, is held vertically by some guiding and/or transport means that hold the sample container. This facilitates the separation and assembly of the holding device. For example, when the retainers 3 are to be separated from each other or connected to each other by disengagement and engagement of the coupling means 7, and when the retainers 3 are held by the retainer 3 in question. 'I when the container contains a sample consisting of body fluids, then closed and has a passage for the removal of the sample?' -or have
When the two sides are completely open, the possibility of horizontal disengagement and engagement of the coupling means 7 causes fluid to pour out of the sample container during the fixing process. The risk is significantly reduced.

A device ( ) 1♂ for automatic analysis of a sample contained in a sample container 15 held by a holding device 1 is configured to insert a metal, conductive injection needle into the k and 11 yoke as usual. It is possible to have at least one working station for insertion into a sample container made of a gas insulating material, for example glass. This equipment is
It is possible to have an air monitoring device having two terminals, one of which is electrically conductively coupled to the needle and the other of which is electrically connected to the needle. The casing 21a and the syringe needle are then connected to an electrically conductive casing 21a at the work station mentioned above.
, forming an electrical capacitor. The monitoring device further monitors the electrical capacitance of the capacitor and the WGM-like capacitance change, that is, the increase in capacitance, that occurs when the needle is immersed in a normally conductive body fluid. Therefore, it can be equipped with electronic circuit means. Therefore, on the basis of this jump-like change in volume during immersion of the injection 3F, it is possible to ascertain when the injection needle has reached the level of body fluid.

A multiple control device connected to the trust device then k,
After the injection needle has reached the water level of the body fluid, it is still necessary to aspirate a predetermined amount of body fluid from the sample container, e.g. It can be controlled so that it is lowered only as far as it can be pipetted into.

The three parts of the retainer 3, each consisting of a one-piece synthetic resin object, namely the body 21 and the two assemblies 31, 41, can be constructed using relatively simple casting tools or
It can be manufactured by extrusion using a casting mold. In this case, the shaping can be carried out completely, ie without any additional working steps, by extrusion. The individual parts of the holding device 1 can therefore be produced economically and then easily assembled.

The holding bag 'f11 can also be modified from various points of view. For example, the axial dimension of the casing and thus the ratio between this axial dimension and the inner diameter of the casing can be made smaller or larger.

If a sample container with an outer diameter lying outside between a given diameter box is to be used, thermal theory limits the diameter range of the cage 3. The dimensions of the image can also be changed. Furthermore, for reasons of manufacturing technology, the slightly conical inner surface part 21e of the casing can optionally be replaced directly with a cylindrical curved surface.

Furthermore, three or more such tongue rows can also be provided in place of a row of tongues gripping the sample container at two axially spaced locations. On top of that,
Optionally, the tongues can also be formed such that each of their relatively long parts grips a sample container inserted into the respective holder 3. Then, in such a formation, in some cases only one archaic row is provided, and these tongues all grip the L(F'l container) in the same axial area. It is also possible to

Furthermore, in some cases, an integral assembly having two or more rows of tongues can be provided, where the tongues are axially spaced apart from each other and the sample container You can also make it grab. In some cases, it is also possible for each holder 3 to be formed from an entirely one-piece body, in which case this body may be provided with k, as the case may be, for connecting adjacent holders 3. A casing jacket 1 divided by slits, an elastic tongue, and a connecting means that can be engaged and released,
Form.

As already mentioned in the introduction, the holding device is further used to hold a tubular container, such as a reaction glass, containing a liquid solvent and/or reagent. You can also do that. At that time, when analyzing body fluids,
, respectively, a given amount of this solvent and/or reagent can be aspirated and mixed with the sample to be analyzed. This construction and operation eliminates all the disadvantages of known holding devices and allows for receiving tubular containers whose outer diameter may vary over a relatively large range. We provide a holding device that allows
A retaining device J is provided which allows mutually adjacent casings to be easily separated from each other in a direction extending transversely to their axes and any arbitrary casing from the phases 'TT, /7. :, '-U', L, further easily and without inserting additional electrodes into the sample container held by the casing, i inserted into the sample container.
