Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a stand for blood sediment measurement. More specifically, a tubular instrument (called a blood sedimentation tube) used to measure the erythrocyte sedimentation rate (called a blood sedimentation tube).
The present invention relates to a stand for measuring blood sedimentation, in which a blood sedimentation tube can be accurately and easily installed to hold the blood sedimentation tube vertically.

<Conventional technology> The conventionally used stand for measuring blood sedimentation is the 5th stand.
As shown in the figure, holders 15 and 16 are provided at the upper and lower parts of the side wall portion 14 of the gantry main body 13, and the holders may be of an insertion type or a clamp type. When installing a blood sedimentation tube, for example, in the case of a blood sedimentation tube of the type that is inserted into a blood collection tube to suck up blood after blood collection, the upper holder 15 holds the blood sedimentation tube 17, and the lower holder 16 holds the blood collection tube 18. was configured to hold. Generally, the surface of the blood sedimentation tube 17 is provided with a scale for measuring blood sedimentation.

<Problems with the prior art> However, the conventional blood sedimentation measurement stand shown in Figure 5 does not have anything to protect the blood sedimentation tube, so the operator's hand or hard object may come into contact with it during the blood sedimentation measurement. This poses a problem as there is a risk that the position may shift or even be damaged. Furthermore, if the holder becomes loose, the blood sedimentation tube may not be installed accurately (that is, perpendicularly to the pedestal portion of the pedestal), which is a problem.

This invention was completed as a result of intensive research in view of the above problems, and it provides a stand for blood sedimentation measurement that allows blood sedimentation tubes to be placed accurately and easily, and that does not cause damage or misalignment due to carelessness. The purpose is to provide.

<Means for solving the problem> An L-shaped mount body consisting of a base part and a side wall part,
The pedestal body comprises a plurality of transparent pipes for inserting blood sedimentation tubes fixed perpendicularly to the pedestal part, and a locking means for holding and fixing the blood sedimentation tubes provided at the lower part of the pipes, A vertical slit is formed in the lower part of the pipe, and the locking means is a plate spring that grows a blood sedimentation tube locking portion formed in an arc shape, and a spring fixing unit that fixes the plate spring to a base portion of the pedestal main body. The plate spring is characterized in that the blood sedimentation tube locking portion of the plate spring is attached so as to protrude from the slit into the pipe.

<Function> The stand for blood sedimentation measurement of the present invention is configured so that the blood sedimentation tube inserted into the transparent pipe fixed vertically to the pedestal body is held and fixed by the locking means. If the outer diameter of the blood sedimentation tube is slightly larger than the outer diameter of the blood sedimentation tube to be applied, or if a method is used to press and lock the blood sedimentation tube against the inner wall of the pipe, simply insert the blood sedimentation tube into the pipe from above. In this case, the blood sedimentation tube is parallel to the wall of the pipe, and therefore the blood sedimentation tube is installed perpendicular to the frame body.

<Example> Next, an example of the present invention will be described based on the drawings.

Figure 1 is a front view of one embodiment of the present invention (scale on the pipe is omitted), Figure 2 is a sectional view taken along line A-A in Figure 1, and Figure 3 is the use of the blood sediment measuring stand of the present invention. Fig. 4 is a sectional view taken along the line B--B in Fig. 3, and Fig. 5 is an explanatory drawing of the usage situation of the conventional blood sediment measuring stand.

As shown in FIGS. 1 and 2, the blood sediment measuring stand 1 of the present invention is comprised of a pedestal main body 4 consisting of a pedestal section 2 and a side wall section 3, a pipe 5, and a locking means 6.

The gantry main body 4 is formed into an L-shape with a pedestal part 2 forming a horizontal surface and a side wall part 3 forming a perpendicular surface to the pedestal part 2. The base part 2 has the same number of holes 7 with the same diameter as the inner diameter of the pipe 5 communicating with the pipe 5, and through these holes 7, a plate is fixed to the back side of the base part 2 with spring fixing screws 8. A spring 9 is inserted into the pipe 5. Further, the side wall portion 3 is colored white to make the scale for blood sediment measurement easier to read. The plate spring 9 is fixed on the frame body 4.
The reason for doing this on the back side is to make the leaf spring 9 and spring fixing screw 8 invisible from the surface, and also to prevent the leaf spring 9 from loosening or breaking due to touching the spring fixing screw 8. This is for the purpose of eliminating unevenness from the surface of the pedestal main body 4, which is likely to be contaminated with blood or chemicals, and making cleaning easier.

Although various materials such as wood, metal, and synthetic resin can be used for the frame body 4, thermoplastic resin is preferable because it is cost-effective, lightweight, and has a beautiful finish. For example, hard vinyl chloride resin ( PVC), polypropylene (PP), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS resin), polystyrene (PS), polymethyl methacrylate (PMMA), styrene-acrylonitrile copolymer (AS resin), etc. be.

As for the locking means, various types of locking means can be used, such as a type that is held between a spring and a pipe wall like the leaf spring 9, a clamp type that is held from both sides, and an insertion type that is inserted and held. However, if the inner diameter of the pipe 5 is sufficiently larger than the outer diameter of the blood sedimentation tube (although considering the cost, it is preferable that the inner diameter of the pipe 5 is slightly larger than the outer diameter of the blood sedimentation tube). However, the locking means is preferably of the leaf spring type.

The pipe 5 is transparent, inserted into a hole 7 bored in the pedestal part 2 of the gantry body, and fixed vertically to the pedestal part 2 using adhesive or the like on the wall and side walls of the hole 7. . The shape of the cut of the pipe 5 is preferably circular in terms of cost and strength, and the side wall portion 3 of the pipe wall
The side to be adhered to is scraped flat to form an adhesive surface. The surface of the transparent pipe 5 is preferably provided with a scale for blood sedimentation measurement, but this scale is unnecessary if the blood sedimentation rod is provided with a scale.

The length of the pipe 5 is determined according to the length of the blood sedimentation tube to prevent the blood sedimentation tube from being buried, but is generally 180 to 220 mm. Further, the inner diameter of the pipe needs to be larger than the outer diameter of the blood sedimentation tube, but from a cost standpoint, it is preferable to form it slightly larger than the outer diameter of the blood sedimentation tube within the range of variation in blood sedimentation tube size. However, when the plate spring 9 is used as the locking means 6 as shown in the embodiment, it is possible to apply the plate spring 9 to blood sedimentation tubes with the largest outer diameter among blood sedimentation tubes on the market so that it can be applied to blood sedimentation tubes of different sizes. It is best to form the inner diameter to match the size of the pipe.

A slit 10 of a size corresponding to the size of the plate spring 9 is provided in the portion of the pipe 5 corresponding to the plate spring 9 in order to cause the blood sedimentation tube locking portion of the plate spring 9 to protrude into the pipe 5. The leaf spring 9 is fixed in the form shown in FIG.
That is, it is carried out on the back side of the platform part 2 and the side wall part 3,
In order to obtain sufficient elastic force of the leaf spring 9, the leaf spring 9 is inserted into a leaf spring insertion groove 11 of a size corresponding to the size of the leaf spring 9 provided on the side wall portion 3. ing.

The material of the pipe 5 may be any material as long as it is transparent and has high rigidity, but from the viewpoint of cost and workability, glass or thermoplastic resin such as hard PVC, PP, PS, PMMA,
AS resin etc. are preferable.

Next, how to use it will be explained. A stand for measuring blood sedimentation is used by placing it on a horizontal table, and the stand for measuring blood sedimentation of the present invention is particularly disclosed in Utility Model Application No. 59-158997 and Utility Model Application No. 60-136786. It is suitable for a blood collection tube for measuring blood sedimentation (the blood sedimentation tube shown in FIGS. 3 and 4, which has both the functions of a blood sedimentation tube and a vacuum blood collection tube). In use, as shown in FIGS. 3 and 4, the blood sedimentation tube 12 is inserted into the pipe 5 from above, and the blood sedimentation tube 12 is locked at an appropriate position with the leaf spring 9. In this case, the blood sedimentation tube 12 is held and fixed by the plate spring 9 against the wall of the pipe 5 on the opposite side to the side wall 3 (the one in front as seen from the observer), as shown in FIG. Even if the tube 12 is not provided with a scale, accurate blood sedimentation measurement can be performed by providing a scale on the surface of the pipe 5.

In addition, when using a conventional type blood sedimentation tube, a separate test tube holding stand (a stand for holding the test tube, configured so that the test tube is located directly below the pipe 5) is required. It is necessary to prepare.

In addition, if the inner diameter of the pipe 5 is made slightly larger than the outer diameter of the blood sedimentation tube to which it is applied, taking into account variations, it is possible to consider a configuration in which the pedestal 2 is used as a locking means, which is not versatile but costs a lot of money. This is advantageous.

<Effects> As is clear from what has been described above, the blood sediment measurement stand of the present invention has the following advantages.

1. Since the blood sedimentation tube is inserted into a transparent pipe and held and fixed, the position may shift due to the operator's hand or a hard object touching it during blood sedimentation measurement, or in some cases, No damage will occur.

2. As long as the pipe is accurately fixed vertically to the base, the blood sedimentation tube can always be installed accurately.

3. By fixing the leaf springs on the back side of the mount body, the springs and screws are no longer visible to the observer, giving a better feel.

Further, in normal use, the fixing screws are not touched by the operator's hands, so the spring does not loosen.

Furthermore, since there are no screw fixing parts on the stand surface, contamination caused by blood or chemicals can be easily cleaned.

4. By attaching a scale to the surface of the pipe and making the side wall surface white, the scale becomes easy to read and therefore accurate and easy observation is possible.

5. Cleaning can be easily performed by fixing the lower part of the pipe so that it passes through the bottom.

6. Since the blood sedimentation tube is fixed by being pressed against the wall of the pipe with a plate spring, blood sedimentation tubes of various sizes can be applied by increasing the inner diameter of the pipe.
