Abstract

PURPOSE:To relatively easily sample liquid without making hands dirty in liquid sampling operation by inserting a liquid sampling stick into a squeezing container, and pressing a liquid absorption member against the top surface of a pressure reception wall and squeezing liquid from the liquid absorption member. CONSTITUTION:Urine required for inspection and diagnosis is discharged to the liquid absorption belt 2 of the liquid sampling stick 1 and thus sampled. Namely the dis charged urine is absorbed by the liquid absorption belt 2. The stick 1 is inserted into a squeezing container 3 from its entrance 7 to make the liquid absorption belt 2 abut on the top surface of the pressure reception wall 5, and the liquid absorption belt 2 is pressed against the top surface of the pressure reception wall 5 by a grip rod 1a to make the liquid absorption belt 2 shrink between the pressure surface 1b and pressure reception wall 5, thereby discharging the urine. Then, the discharged urine passes through the through hole 5a of the pressure reception wall 5 and exits from the squeezing container 3 from its exit 6, so the urine is collected. Further, the urine discharging to the liquid absorption belt 2 is performed by arranging the liquid absorp tion belt 2 at the best position while confirming its position because the liquid absorp tion belt 2 is mounted atop of the grip rod 1a. Thus, liquid is easily sampled without making the hands dirty.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention generally relates to a liquid sampling device, and more particularly to a liquid sampling device for collecting a small amount of test sample/diagnostic liquid for use in medical diagnostic tests.

BACKGROUND TECHNOLOGY Conventionally, when detecting proteins and sugars in medical examinations at medical institutions, or diagnosing whether a woman is pregnant, it is generally done by collecting urine and testing it.
The diagnosis is made.

Below, as an example, the procedure for pregnancy diagnosis will be briefly introduced. For this diagnosis, a urine collection device is used that houses reagents and instruments used in the diagnosis. The urine collection device stores test tubes, droppers, reagents, diagnostic agents, and the like. To determine whether a woman is pregnant, a certain type of reagent B is added to the woman's urine, a control ball that reacts with color to certain hormones is immersed in the urine to which reagent B has been added, and then the control ball is immersed in reagent A. Diagnosis is made through a series of procedures in which the control ball is immersed and diagnosed based on the color that develops. By the way, urine, which is a liquid to be diagnosed, is usually collected directly from excreted urine using a urine collection device or the like. Then, the urine is transferred into a test tube using a dropper, and the patient is then diagnosed according to the above procedure. However, this collection work
It is an act that is inconvenient for women, and sometimes
It is also unsanitary, such as getting your hands dirty. In other words, the above work is
It's hard to say that it's the best work that everyone often feels.

As a result of recent remarkable technological innovations in the medical field, the amount of test fluid required for diagnosis has been significantly reduced compared to the past. Therefore, although the conventional method is efficient, it cannot necessarily be said to be the best method. Traditional methods are particularly difficult to use when the person responsible for collecting is a woman. Therefore, there is a need for a liquid sampling means that is relatively simple and cleaner than conventional methods.

Technical Problems of the Present Invention The present invention has been made in view of these demands. Therefore, the technical problem to be solved by the present invention is to collect liquid relatively easily without getting your hands dirty during the above-mentioned urine collection work or other liquid collection work carried out in chemical experiments, etc. The goal is to provide equipment.

Summary of the present invention (structure, operation, effect) In order to achieve the above technical problem, the present invention was constructed as follows.

That is, the liquid sampling device according to the present invention includes a liquid sampling stick including a grip bar having a pressing surface at its tip, a liquid absorbing member attached to the pressing surface, and a lower end of the inner circumference of the cylindrical body. and a diaphragm formed by arranging a pressure receiving wall having a through hole substantially perpendicular to the axis of the cylindrical body.

According to the above configuration, the necessary liquid can be collected by impregnating the liquid absorbing member of the liquid sampling stick by spraying or dipping the liquid into the liquid absorbing member. That is, the liquid impregnated into the liquid absorbing member is released from the liquid absorbing member when the liquid absorbing member is pressed against the pressing surface and contracts. More specifically, in order to contract the liquid absorbing member, prepare the above-mentioned wringer, insert the liquid sampling stick into the wringer from one opening, and insert the stick into the wringer from one opening on the side opposite to the pressing surface of the liquid absorbing member. The side surface of the wringer is brought into contact with the upper surface of the pressure receiving wall of the wringer, and the liquid sampling stick is further pressed against the upper surface. This causes the liquid-absorbing member to contract and release the liquid impregnating it. Then, the liquid passes through the through hole in the pressure receiving wall and further flows out of the constrictor from the other opening of the constrictor. The released liquid may then be collected in another container. Moreover, since the liquid absorbing member is attached to the tip of the gripping rod, it is possible to effectively prevent liquid from getting on the hands during liquid collection work.

Furthermore, securing the necessary amount of liquid can be achieved by changing the volume of the liquid absorbing member.

Furthermore, the act of collecting liquid can be performed relatively easily by selecting the grip stick length that is convenient for the person performing liquid sampling by providing several different lengths of the grip stick of the liquid sampling stick. becomes possible. Furthermore, it is possible to easily and effectively collect the sampled liquid from the liquid sampling stick by using the above-mentioned squeeze device.

In other words, it becomes possible to change the fluid collection work into an easy and clean work, which is the intention of the present invention, especially for the fluid collection work performed by women.

EXAMPLE An example of the present invention will be specifically described below with reference to FIG. 1.2. It should be noted that the present invention is assumed to be used during urine collection work in a urinalysis test, which is its main use, and the present embodiment will be described with this case in mind.

FIG. 1 shows the entire liquid collection stick. In the figure,
1a indicates a grip bar. The grip rod 1a is a rod made of synthetic resin and has a circular cross section, and is provided with a liquid absorption band 2 at its tip for absorbing liquid.

The liquid absorption band 2 is formed by a pressing surface 1c of an absorption band mounting plate 1b, which is a plate-shaped member integrally formed at the tip of the gripping rod 1a.
It is attached with adhesive etc.

The liquid absorption band 2 is made of a material that efficiently absorbs liquid, such as cotton or sponge. In addition, its cross-sectional shape is
It does not have to be circular, rectangular, or any other particularly limited shape.

Furthermore, FIG. 2 shows a state in which the liquid sampling stick 1 is inserted into a squeezer exclusively for squeezing out the liquid that collects urine collected with the liquid sampling stick 1.

That is, it is a cylindrical container made of glass or synthetic resin, and has a trumpet-shaped entrance lower end with a cross section wider than the open cross section at the upper end, and an outlet narrowed to be narrower than the open cross section for draining urine at the lower end. The restrictor 3 equipped with the restrictor 3 has a generally disc-shaped pressure receiving wall 5 formed at the lower end of the inner circumference of the restrictor 3 and substantially perpendicular to the axis of the restrictor 3. A through hole (5a) is formed in the pressure receiving wall 5.

According to the above configuration, urine required for testing and diagnosis can be collected by urinating into the liquid absorption band 2 of the liquid sampling stick 1. That is, the urinated urine is absorbed into the liquid absorption band 2.

Then, insert the liquid sampling stick l into the wringer 3 from the input lower part, bring the liquid absorption band 2 into contact with the upper surface of the pressure receiving wall 5, and further apply the liquid absorption band 2 to the area using the grip rod l. When pressed against the upper surface of the pressure-receiving wall 5, the liquid-absorbing band 2 contracts between the pressing surface 1b and the upper surface of the pressure-receiving wall 5 and releases urine. The released urine passes through the through hole 5a of the pressure receiving wall 5 and exits the squeezer 3 from the outlet 6 of the squeezer 3. Therefore, this released urine may be collected.

In addition, urinating into the liquid absorption band 2 is performed by placing it at the optimum position while visually checking the position of the liquid absorption band 2, since the liquid absorption band 2 is attached to the tip of the grip rod 1a. . This act is an act that can be performed without any special preparation or difficulty.

In this way, the collected urine is used as a diagnostic liquid for diagnosing the presence or absence of pregnancy according to the procedure described above.

In the above configuration, the act of collecting urine is not an act that involves any difficulty compared to the conventional method (it can even be said that it is an easier method for women.Furthermore, the act of collecting urine manually is not difficult for women). The user must grasp the urine collection device or paper tip and urinate into the urine collection device or paper tip, and during this process, the user often gets his hands dirty, so it cannot be said that the urine collection work is clean.However, in this example, Concerns about getting your hands dirty are eliminated because urine only needs to be urinated onto the liquid absorption band 2 located a certain distance away from your hands.In other words, this embodiment is relatively simple and easy to use. It can be said that it is a clean liquid sampling device that does not contaminate the liquid.

In addition, when it is necessary to remove impurities from collected urine or liquid for the purpose of examination or diagnosis, a filter 8 for removing impurities is placed between the pressure receiving wall 5 and the output lower part of the wringer 3, as shown in FIG. This can be handled by placing it between the two.

Although the above description has been made in relation to urine collection associated with pregnancy diagnosis, the present invention is not limited to urine collection, but can also be used when collecting other fluids.

That is, the present invention can be applied to the case where a medicinal solution is applied to an affected area for treatment. A suitable example is shown below.

As a modification of the above embodiment, when there is a diseased area in a hard-to-reach place such as the throat, the liquid-absorbing band 2 can be impregnated with a medicinal solution and used as a means of applying it to the affected area. Conventionally, the method of applying a medicinal solution to the affected area was to apply the medicinal solution to a cotton swab or the like and apply it to the affected area, but the amount of medicinal solution that can be impregnated into a cotton swab is not so large. Therefore, if the affected area is large, repeated application work to the affected area is required. Moreover, the pressure exerted on the affected area by the swab's core may cause pain to the affected area, and great care must be taken when pressing the line of the swab to release or apply the medicinal solution to the affected area.

However, in this modification, the part corresponding to the tightening part, that is, the liquid absorption band 2, does not have anything corresponding to the core, so the medicinal solution can be released or applied to the affected area without giving a sharp pressure sensation to the affected area. It is possible.

Furthermore, the amount of the medicinal solution to be impregnated can be adjusted by adjusting the volume of the liquid absorption zone 2, making it easy to deal with diseases that involve a relatively wide area.

In addition to the medical field, it can also be used in fields where liquid sampling is required, such as in chemical experiments. In other words, it can be said that this is a suitable liquid sampling device for collecting liquid without soiling the hands, or for collecting liquid that is dangerous if it adheres to the hands.
