Description

  The present invention relates to a body fluid collecting jig that can easily and accurately collect body fluids of organisms including blood.

  In order to grasp the health condition of living organisms including the human body and to test for diseases, etc., body fluids such as blood are collected and tested. The collected body fluid is separated and examined for various component amounts, and the health condition and diseased condition are examined using various reagents. In this examination, it is often necessary that the amount of body fluid collected is a predetermined amount. For example, when a component in a body fluid is separated and inspected, it may be necessary to make a comparison with the collected body fluid by volume or weight. In this case, it is necessary that the volume and weight of the collected body fluid be exactly a predetermined amount.

  For example, if the volume and weight of the collected body fluid are different, depending on the body fluid sample to be inspected, the ratio of the inspected component becomes inaccurate, and a correct inspection cannot be performed. For example, when calculating the proportion of red blood cells or hemoglobin in the body fluid, if the amount of body fluid varies, the exact proportion cannot be calculated.

  In addition, when the collected body fluid is tested using various reagents, the collected body fluid needs to be diluted to a predetermined concentration. In this dilution, a diluent is used, and diluted to a predetermined concentration by mixing the diluent with the body fluid. Also in this dilution, the volume and weight of the collected body fluid are a predetermined amount, which is a necessary condition for dilution to a predetermined concentration.

  For example, if the volume and weight of the collected body fluid are different, the predetermined concentration to be diluted may be different. If the diluted concentration is different, there is a problem that the reaction with the reagent used becomes inaccurate, and the examination of diseases or the like cannot be performed accurately.

  As described above, when the collected body fluid is inspected to check the health condition or to check the disease, it is necessary to accurately collect a predetermined amount of the body fluid. On the other hand, the human body and organisms from which body fluids are collected naturally have individual differences, and there is a problem that it is not easy to collect a predetermined amount of body fluids.

  In such a situation, several techniques for collecting body fluid have been proposed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).

JP 2010-51397 A JP 2008-279031 A JP 2008-154702 A

  Patent Document 1 is provided between a container main body for collecting and storing blood used for testing, a blood inflow port for flowing blood into the container main body 2, and the blood inflow port and the container main body. The container body has a tubular passage through which blood flows from the blood inflow port, and a sweeping means having a hydrophobic filter is provided at the end of the tubular passage. A test blood container is disclosed.

  However, the test blood container disclosed in Patent Document 1 is a very large-scale device, which requires labor for collection as well as cost. In addition, the fact that the device is large-scaled also causes a problem of fear for patients who receive body fluid collection. Of course, there is also a possibility of causing an operation error for an operator who performs sampling.

  Patent Document 2 is provided with a blood collection tube that sucks blood by capillary action and a pair of guides that are separated from each other for pressing a finger, and is configured so that the belly of the finger pressed through the guide can be visually observed. In addition, a blood collection tool is disclosed in which a blood suction port opened at the tip of the blood collection tube is positioned between the guides.

  However, the blood collection tool disclosed in Patent Document 2 uses a needle-like suction port that is inserted into the belly of a finger as shown in the figure. The use of a needle-like suction port has a problem of forcing pain and pain to a patient to be collected. Such pain and pain lead to a problem that causes mistakes even when a predetermined amount is collected. Of course, there are also problems that cause fear.

  In addition, the blood collection tool disclosed in Patent Document 2 is intended to collect a predetermined amount of blood, but it is difficult for an operator to visually confirm whether blood has been collected reliably. For this reason, it cannot be confirmed whether the target predetermined amount has been reliably collected, causing a problem in the inspection when the predetermined amount is not reached.

  Patent Document 3 includes a blood collection tube main body having an opening at one end, a blood introduction port, and a lid member having a blood channel that communicates the blood introduction port and the blood collection tube main body. A decompression blood collection chamber for sucking blood from the blood introduction port by action, and a reagent storage chamber for storing a reagent for diluting the blood, and the lid member collects a predetermined amount of blood from the blood flow path, Disclosed is a quantitative blood collection tube having a quantitative collection part to be introduced.

  However, the blood collection tube disclosed in Patent Document 3 collects blood by piercing a human body with a needle-like member, as in Patent Document 2. The use of a needle-like suction port has a problem of forcing pain and pain to a patient to be collected. Such pain and pain lead to a problem that causes mistakes even when a predetermined amount is collected. Of course, there are also problems that cause fear.

  In addition, a specialized container such as a decompression container is required, and there is a problem that the apparatus becomes large. In the case of collecting blood of several hundred cc, the blood collection tube disclosed in Patent Document 3 is appropriate, but there are many cases in which less body fluid is collected depending on the examination contents. Even when such a small amount of body fluid collection is sufficient, the use of the blood collection tube disclosed in Patent Document 3 places a heavy burden on the patient. Of course, the burden on the operator is heavy.

  Also, in recent years, inspection methods and inspection apparatuses have advanced, and various inspections can be performed with a small amount of body fluid. In addition, an examination method in which a patient to be collected collects a body fluid and submits it to a laboratory is also progressing. In such a case, it is preferable that a small amount of body fluid can be collected accurately and easily while reducing pain.

  However, the technique of Patent Document 3 has a problem that is not suitable for such an operator's own collection operation or a small amount of body fluid collection.

  As described above, the conventional techniques represented by Patent Documents 1 to 3 have the following problems.

  (Problem 1) There is a problem that the collection tool and the apparatus are large and the collection cost increases in addition to the manufacturing cost.

  (Problem 2) When collecting, it is necessary to pierce the human body or the like with a needle-like member, and there is a problem of giving fear or pain to the patient or the like. Due to this problem, there is a problem that the patient who needs the examination does not actively respond to the collection of the body fluid and the discovery of the disease is delayed.

  (Problem 3) There is a problem that the labor and burden of the operator are large because the apparatus is large-scale or the needle needs to be inserted.

  (Problem 4) There is a problem that it is difficult to easily and simply collect a small predetermined amount of body fluid.

  (Problem 5) There is a problem that it is difficult to immediately confirm at the place where the collection work is performed whether the body fluid is reliably collected in the collection jig.

  An object of the present invention is to solve these problems and to provide a collection jig that reliably collects a predetermined amount of body fluid while being simple and simple while reducing fear and pain to patients and the like. And

In view of the above problems, the body fluid collection jig of the present invention has a plate-shaped handle,
A plate-shaped sampling part connected to the handle;
A mouthpiece provided on the end face of the tip of the sampling part;
A housing portion communicating with the mouthpiece and having a predetermined housing volume,
The accommodating part is provided inside the collecting part,
The containment section
A first accommodating portion along the outer periphery of the sampling portion;
A second housing part surrounded by the first housing part,
The first housing part has a first housing volume, and the second housing part has a second housing volume.

  The body fluid collecting jig of the present invention can accurately collect a predetermined amount of body fluid while having a simple configuration. In addition, the simple configuration can reduce the manufacturing cost and the sampling cost.

  Further, since the needle-like member is not stabbed into a patient or the like, there is little fear or pain for the patient. As a result, body fluid can be collected by the patient himself / herself, and labor can be reduced even by collection by an operator. As a result, there is a merit that leads to early detection of diseases.

  Furthermore, after collecting a predetermined amount of a small amount of body fluid, the state of collection can be visually confirmed on the spot. This visual confirmation can reduce inconvenience such as redo after collection. Of course, by collecting a predetermined amount necessary for the examination, it is possible to save the labor and cost of measuring a larger amount of the collected body fluid and to reduce the labor and cost of the whole examination.

  (Embodiment 1)

  Embodiment 1 will be described.

(Overview)
First, an overall outline of the body fluid collection jig in Embodiment 1 will be described with reference to FIGS. 1 and 2. FIG. 1 is a plan view of a body fluid collection jig according to Embodiment 1 of the present invention. FIG. 2 is a front view of the body fluid collection jig according to Embodiment 1 of the present invention. FIG. 2 shows a state as seen from the mouthpiece 4 side of the body fluid sampling jig 1 shown in FIG.

  The body fluid collection jig 1 includes a handle 2, a collection unit 3, a mouthpiece 4, and a storage unit 5. The handle 2 is a plate-like member. The collection unit 3 is connected to the handle 2 and is a plate-like member like the handle 2. The collection unit 3 is integrated with the handle 2. The mouthpiece 4 is provided at the tip of the collection unit 3. The storage unit 5 communicates with the mouthpiece 4 and has a predetermined storage volume inside the sampling unit 3.

  As shown in FIG. 1, the body fluid collecting jig 1 is a plate-shaped jig directed from the root toward the tip. The handle 2 and the collection unit 3 form the outer shape of the body fluid collection jig 1. As shown in FIGS. 1 and 2, the outer shape is a thin plate because the handle 2 and the collection unit 3 are thin plate members. The body fluid collecting jig 1 has a handle 2 at the base and a mouthpiece 4 at the tip.

  As shown in FIG. 2, the mouthpiece 4 is formed by a gap at the tip of the sampling part 3. For example, the mouthpiece 4 is preferably slit-shaped. By being a narrow gap like a slit, the mouthpiece 4 can suck up the body fluid applied to the tip of the mouthpiece 4 by osmotic pressure.

  For example, the mouthpiece 4 is pressed against the outer skin from which human body fluid or biological fluid leaks. Alternatively, the mouthpiece 4 is pressed against the bodily fluid taken out from the human body or organism by some method and accommodated in the container. By this pressing, the mouthpiece 4 sucks up body fluid using osmotic pressure.

  The accommodating part 5 communicates with the mouthpiece 4 and is formed inside the collecting part 3. For this reason, the body fluid sucked up from the mouthpiece 4 is filled in the housing part 5. By this sucking and filling, the storage unit 5 can store body fluid corresponding to a predetermined storage volume. As described above, the body fluid collecting jig 1 can reliably collect the body fluid in the determined accommodation volume by the suction at the suction mouth 4 and the accommodation in the accommodation portion 5 after the suction.

  Here, the accommodating part 5 is connected to the slit-like mouthpiece 4 shown in FIG. For this reason, the accommodating part 5 is also a narrow space. As a result, the bodily fluid sucked up by the mouthpiece 4 fills the entire accommodating portion 5. That is, the storage unit 5 can reliably collect body fluid corresponding to the storage volume.

  The accommodating part 5 has a first accommodating part 6 along the outer periphery of the sampling part 4 and a second accommodating part 7 surrounded by the first accommodating part 6. The first accommodating portion 6 has a first accommodating volume, and the second accommodating portion 7 has a second accommodating volume. That is, the sum of the first storage volume and the second storage volume is the storage volume of the storage unit 5.

  Since the accommodating part 5 is divided | segmented into the 1st accommodating part 6 and the 2nd accommodating part 7, there exists a merit which an operator tends to confirm accommodation of the bodily fluid in the accommodating part 5. FIG. For example, the visible characteristics of the first housing portion 6 and the visible characteristics of the second housing portion 7 are different. When the respective visible characteristics are different, the operator can confirm the accommodation state in each of the first accommodation unit 6 and the second accommodation unit 7. As a result of this confirmation, it can be confirmed whether the accommodating part 5 is collecting | collecting the bodily fluid in an accommodation volume reliably.

  Further, by being divided into the first accommodating portion 6 and the second accommodating portion 7, only a state of being collected by the body fluid collecting jig 1 can be used to perform a certain inspection based on the body fluid.

  As described above, the body fluid collecting jig 1 can accurately collect body fluid in a predetermined accommodation volume, and can realize inspections in various variations.

  Next, the detail of each part is demonstrated.

(handle)
The handle 2 is a portion that is gripped when an operator collects body fluid using the body fluid collection jig 1. The body fluid collection jig 1 is used by being applied to a human body or a beaker from which body fluids are collected. For this reason, the body fluid collection jig 1 is small. For this reason, in order to produce ease of handling for the operator, a handle 2 is provided.

  The handle 2 is a thin plate-like member. Moreover, it is suitable that it is plate-shaped according to the collection part 3 connected to the tip of the handle 2. With this configuration, the operator can easily handle the body fluid collection jig 1 by holding the handle 2.

  It is also preferable that the handle 2 is made of a resin, like the whole body fluid collection jig 1. This is because it is made of resin, so that the cost is reduced and the handling becomes easy. Moreover, it is because the visibility of the accommodating part 5 increases and it is easy to confirm the state of body fluid collection.

  It is also appropriate that a part of the handle 2 has a dent so that the operator can easily grasp it with a finger.

  It is also preferable that the handle 2 has a scale. This is because by having the scale, the working accuracy can be increased when the body fluid sampling jig 1 is used in another inspection apparatus.

(Collecting part)
The collection unit 3 includes a suction port 4 at the tip and a storage unit 5 that is formed inside and communicates with the suction port 4. By means of the mouthpiece 4 and the accommodating part 5, the collecting part 3 can collect body fluid.

  The sampling unit 3 applies the tip that is the mouthpiece 4 to a human body or the like. At this time, the body fluid is sucked up by the osmotic pressure of the mouthpiece 4. For this reason, it is also preferable that the tip of the sampling part 3 has a tapered part or a curved part. By having a taper part or a curved part (which may have both), the leading end of the collection part 3 has different arrival positions on the left and right. FIG. 1 shows a state where the left and right arrival positions are different.

  Since the right and left reaching positions at the tip of the collection part 3 are different depending on the tapered part and the curved part, the body fluid can be easily sucked up at the mouthpiece 4.

  The mouthpiece 4 sucks up body fluid with osmotic pressure. If the left and right arrival positions are different, the tip of the sampling part 3 has a protruding part 31 on either the left or right side. The presence of the protruding portion 31 makes it easier to apply to the human body. In particular, when the protruding portion 31 comes into contact with a human body or the like in a small area, the force of sucking up the mouthpiece 4 is increased.

  Alternatively, the operator can apply the protruding portion 31 to the human body first, and then press the tapered portion or the curved portion at the tip against the human body in order, so that the sucking by the mouthpiece 4 can be performed more smoothly.

  It is also preferable that the mouthpiece 4 is subjected to a hydrophilic treatment in order to ensure the suction of body fluid by osmotic pressure. Since the hydrophilic treatment is performed, the suction mouth 4 can perform higher suction, coupled with physical osmotic pressure due to a narrow gap.

(Container)
The accommodating part 5 communicates with the mouthpiece 4 and is formed in the internal space of the sampling part 3. The accommodating portion 5 is a thin plate-like member, and the mouthpiece 4 is a slit at the tip of the thin plate-like member, so that the accommodating portion 5 is also a thin space.

  The accommodating portion 5 also has an osmotic pressure because it is a thin space and communicates with the mouthpiece 4. Due to the continuous osmotic pressure between the mouthpiece 4 and the housing portion 5, the body fluid sucked up by the mouthpiece 4 enters the housing portion 5 as it is. By this continuous action, the storage unit 5 can collect and store body fluid from the mouthpiece 4.

  Here, similarly to the mouthpiece 4, it is preferable that the inner surface of the accommodating portion 5 is also subjected to a hydrophilic treatment. This is because the collection of body fluid by the storage unit 5 is more reliable.

  The accommodating part 5 has a predetermined accommodating volume. This accommodation volume corresponds to the amount required when the body fluid collected by the body fluid collection jig 1 is inspected. By having the predetermined accommodation volume, the body fluid collection jig 1 can reliably collect the necessary collection amount. Regardless of the body fluid collection jig 1, the same collection amount can be collected every time it is collected, so that there is no variation or mistake in inspection.

  The storage volume of the storage unit 5 may be changed as appropriate depending on the purpose of use of the body fluid collection jig 1. In addition, different body fluid collection jigs 1 having storage portions 5 with different storage volumes may be prepared.

  The accommodating part 5 has a first accommodating part 6 and a second accommodating part 7. The first storage unit 6 is the collection unit 3 and is provided along the outer periphery of the storage unit 5. That is, the first accommodating portion 6 communicates with the mouthpiece 4. On the other hand, the second housing part 7 is surrounded by the first housing part 6. The second accommodating portion 7 does not communicate with the mouthpiece 4.

  The body fluid sucked up by the mouthpiece 4 is stored in the first storage portion 6 with osmotic pressure. Here, the 1st accommodating part 6 is pinched | interposed with the transparent or semi-transparent member. For example, in the sampling part 3, if the part corresponding to the 1st accommodating part 6 is transparent or translucent, the 1st accommodating part 6 will become transparent or translucent.

  By this form, the body fluid accommodated in the 1st accommodating part 6 can be visually confirmed from the outside. By confirming that body fluid is stored in the first storage unit 6 by visual observation, it is confirmed by an operator that the storage unit 5 stores body fluid of a volume corresponding to the first storage volume or more. it can. For example, when the body fluid collection jig 1 needs to collect body fluid larger than the first accommodation volume, it can be confirmed by visual inspection of the first accommodation portion 6 that the necessary amount is collected.

  Moreover, it is also suitable that the outer wall of the 1st accommodating part 6 has a polarization characteristic. By having a polarization characteristic, the 1st accommodating part 6 can show reliably that the bodily fluid is accommodated inside. FIG. 3 is a plan view of the bodily fluid collecting jig according to Embodiment 1 of the present invention.

  As shown in FIG. 3, when the first storage unit 6 stores body fluid, the storage state can be determined by the polarization characteristics of the first storage unit 6. For example, even when the color of the body fluid is small, the color of the outer wall of the first container 6 changes as shown in FIG. 3 because the outer wall of the first container 6 has polarization characteristics. It can be seen that the first container 6 reliably contains the body fluid in the first accommodation volume due to this change in color.

  The operator can confirm that the collection of the first accommodation volume has been performed only by visual inspection of the first accommodation unit 6 in the collection of the body fluid using the body fluid collection jig 1.

  The 2nd accommodating part 7 is provided in the position which makes the 1st accommodating part 6 the exterior. The second housing part 7 together with the first housing part 6 forms the housing part 5. The second storage portion 7 has a second storage volume and can store body fluid in the second storage volume.

(Easy movement of body fluid from the first container to the second container)
Since the storage unit 5 is divided into the first storage unit 6 and the second storage unit 7, the body fluid stored in the same storage unit 5 is divided into the first storage unit 6 and the second storage unit 7. Can be accommodated. This divided accommodation has the advantage of increasing the ease of accommodation through the mouthpiece 4.

  It is also preferable that the internal space of the second accommodating portion 7 is larger than that of the first accommodating portion 6. First, the bodily fluid sucked up from the mouthpiece 4 is accommodated in the first accommodating portion 6 with an osmotic pressure applied from the mouthpiece 4 to the first accommodating portion 6. Next, the body fluid stored in the first storage unit 6 is moved from the first storage unit 6 to the second storage unit 7 by osmotic pressure and stored. In particular, since the thickness of the internal space of the second storage portion 7 is larger than the thickness of the internal space of the first storage portion 6, osmotic pressure from the first storage portion 6 to the second storage portion 7 is likely to occur.

  The collection unit 5 is in the order of the mouthpiece 4, the first storage unit 6, and the second storage unit 7. At this time, the continuity of the osmotic pressure is maintained by dividing the first accommodating portion 6 and the second accommodating portion 7 into different thicknesses, rather than the entire accommodating portion 5 having a single structure. Thus, the collecting unit 5 can reliably collect the body fluid.

  Since the storage part 5 is divided | segmented into the 1st storage part 6 and the 2nd storage part 7, even if it is the same storage volume, a bodily fluid can be extract | collected more reliably. In addition, it is possible to cope with a larger accommodation volume by sucking up by gradual osmotic pressure by dividing. This is an advantage based on a configuration in which the first housing portion 6 is first present and then the second housing portion 7 is present, based on the mouthpiece 4.

(Realization of different purposes)
Furthermore, there is also an advantage that the body fluid in the first housing portion 6 and the body fluid in the second housing portion 7 can be used for different examinations due to the divided housing. For example, when performing a simple test using only the body fluid collection jig 1, different tests can be performed using the first storage unit 6 and the second storage unit 7.

  Or the 1st accommodating part 6 can make it confirm that the bodily fluid sampling was performed reliably, and the 2nd accommodating part 7 can make a simple test | inspection by irradiating reflected light and transmitted light. it can. As described above, since the storage unit 5 is divided into the first storage unit 6 and the second storage unit 7, both the collection confirmation and the simple inspection can be performed.

  The body fluid collecting jig 1 collects body fluid by applying the mouthpiece 4 to a human body or an instrument. At this time, the 1st accommodating part 6 can confirm the state of a bodily fluid collection | recovery. For example, as described above, since the outer wall of the first housing portion 6 has polarization characteristics, the state in which the first housing portion 6 contains body fluid can be visually confirmed.

  For this reason, it is appropriate that the first accommodation volume of the first accommodation portion 6 is a minimum necessary for applying the body fluid collected by the body fluid collection jig 1 to another inspection apparatus. As long as the first storage unit 6 that can be visually confirmed stores body fluid, it is guaranteed that the body fluid of the first storage volume is collected.

  On the other hand, the 2nd accommodating part 7 can also test | inspect the body fluid to receive, receiving at least one of reflected light and transmitted light. Since this inspection is possible, a simple inspection can be performed before the collected body fluid is applied to another inspection apparatus. Here, when the 2nd accommodating part 7 is used for performing such a simple test | inspection, according to the quantity of bodily fluid required for a simple test | inspection, the 2nd accommodation volume of the 2nd accommodating part 7 is set. It only has to be decided.

  In other words, the second housing portion 7 may be formed so as to have a second housing volume necessary for inspection by reflected light or transmitted light in the second housing portion 7.

  Of course, the second accommodating portion 7 is also preferably a transparent or translucent outer wall. With this configuration, it can be visually confirmed that the second storage portion 7 stores body fluid. In addition, the outer wall of the second housing portion 7 may also have polarization characteristics. By having the polarization characteristic, it can be visually confirmed that the second storage unit 7 stores the body fluid.

  At this time, it is also preferable that the outer wall of the first housing portion 6 and the outer wall of the second housing portion 7 differ in at least one of color, transmittance, and polarization. Since these are different, the operator can visually confirm the accommodation of the body fluid in the first storage unit 6 and the storage of the body fluid in the second storage unit 7. FIG. 4 is a plan view of the body fluid sampling jig in Embodiment 1 of the present invention.

  In the body fluid collection jig 1 shown in FIG. 4, body fluid is stored in the second storage portion 7, and the outer wall of the second storage portion 7 has a different color from the outer wall of the first storage portion 6. When the body fluid is stored due to the difference in transmittance and polarization characteristics, the first storage unit 6 and the second storage unit 7 have different apparent colors.
