Description

  The present invention relates to a pseudo-plantar for training blood sampling treatment from the sole, and in particular blood training from a newborn baby sole.

  Blood sampling from the sole of a newborn is currently a medical practice that can only be performed by a doctor. Specifically, the injection needle is accurately inserted at a position of 1.2 to 1.5 mm (recommended 1.3 to 1.4 mm) from the surface of the sole, and blood collection is performed.

  A pseudo plantar for training the blood collection procedure has not been developed so far. However, there is a possibility that nurses will be authorized to perform the blood collection procedure in the future. In such an era, development of a pseudo-plantar for training the blood collection procedure at nursing schools, etc. desired.

  On the other hand, a pseudo hand arm for training blood collection from the wrist is known from Patent Document 1 (Japanese Patent Laid-Open No. 2006-317570) and the like.

JP 2006-317570 A

  The present invention has been devised to pay attention to the above problems and to effectively solve them. It is an object of the present invention to provide a simulated plantar for training blood collection procedures from the plantar.

  The present invention provides a pseudo-plantar for training blood collection treatment having at least a buttock, a pseudo-vascular element filled with pseudo-blood, a pseudo-skin layer covering the surface of the pseudo-vascular element, and the pseudo-vascular element The pseudo-skin layer has an increased thickness in the central region of the buttocks and a thickness of 1.2 to 1.5 mm in the planned blood collection region This is a pseudo-plantar for training a blood collection procedure.

  According to the present invention, since the thickness of the central region of the buttocks is increased, it is possible to obtain the same tactile sensation or texture as the actual sole, while the thickness of the pseudo skin layer in the planned blood collection region is Since it is 1.2 to 1.5 mm, the degree of simulation of blood collection treatment is also high. In addition, since the back side of the pseudo vascular element is supported by the elastic element, it is possible to effectively prevent the pseudo vascular element from retreating to the back side even if training is repeated.

  Preferably, the pseudo vascular element is formed of a cotton material (cotton). According to the examination experiment of the present inventors, the cotton material filled with pseudo blood has characteristics very close to those of an actual blood vessel in terms of the surface tension of the pseudo blood acting on the injection needle when the injection needle is inserted. According to the experiment conducted by the present inventors, in addition to cotton (cotton), cotton fabric, silk, silk cotton, sponge, pulp, high molecular weight polymer, superabsorbent polymer, nylon fiber, polyester, wool, felt, alpaca hair Japanese paper and the like can also be suitably used to some extent, but cotton is most preferable.

  On the other hand, the elastic element is preferably formed of a sponge material. The sponge material may be any of nylon sponge, rubber sponge, resin sponge and the like. According to the examination experiment of the present inventors, in addition to the sponge material, foamed urethane, foamable silicone (foam silicone), foamable latex (foam latex), foamed polyurethane foam, etc. can be suitably used to some extent. Sponge material is most preferred.

  When a sponge material is used as the elastic element, it is possible to employ a mode in which pseudo blood is filled into the pseudo blood vessel element via the sponge material by utilizing the porous nature of the sponge material. Specifically, a simulated blood supply path for supplying simulated blood to the simulated blood vessel element can be formed as a path that passes through the sponge material.

  Preferably, the pseudo sole includes a lower ankle portion and an annular cover portion extending further upward from the lower ankle portion, and the pseudo upper ankle having a pseudo blood supply tube It can be connected to the ankle portion, and the annular cover portion is in close contact with the periphery of the pseudo upper ankle. In this case, since the pseudo blood supply device only needs to be connected to the pseudo blood supply pipe of the pseudo upper ankle, the degree of freedom of arrangement is increased, and the pseudo sole and the pseudo upper ankle are coupled without leakage of the pseudo blood. In addition, there is no risk of contamination of the training site for blood collection procedures.

  According to the present invention, since the thickness of the central region of the buttocks is increased, it is possible to obtain the same tactile sensation or texture as the actual sole, while the thickness of the pseudo skin layer in the planned blood collection region is Since the thickness is 1.2 to 1.5 mm, the accuracy of blood collection treatment is high. Moreover, since the back side of the pseudo vascular element is supported by the elastic element, the pseudo vascular element is effectively prevented from retreating to the back side even if training is repeated.

It is a schematic perspective view which shows the state which removed the pseudo sole of FIG. 1 from the pseudo upper ankle. FIG. 4 is a cross-sectional view of the pseudo sole of FIG. 3 taken along the line IV-IV.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a schematic view showing a newborn doll 100 having a simulated sole 10 for training a blood collection procedure according to an embodiment of the present invention.

  As shown in FIG. 1, a portion corresponding to the sole of the right foot of the newborn doll 100 is configured as a pseudo sole 10. As shown in FIG. 1, the pseudo sole 10 according to the present embodiment includes a heel part 11, a toe part 12, a lower ankle part 13, and an annular cover part that extends further upward from the lower ankle part 13. 14.

  On the other hand, a pseudo blood supply tube 51 is built in the pseudo upper ankle 50 configured as a part of the newborn doll 100. The pseudo blood supply pipe 51 is exposed to the outside from around a portion corresponding to the back of the eaves. And the annular cover part 14 is closely_contact | adhering to the circumference | surroundings of the pseudo upper ankle 50, and thereby, the pseudo sole 10 and the pseudo upper ankle 50 are coupled so that the pseudo blood does not leak. A pseudo blood supply device (not shown) is connected to the externally exposed portion of the pseudo blood supply pipe 51 when additional pseudo blood is filled.

  2 is a schematic perspective view of the pseudo sole 10 of FIG. 1, and FIG. 3 is a schematic perspective view showing a state in which the pseudo sole 10 of FIG. 1 is removed from the pseudo upper ankle 50. 4 is a cross-sectional view of the pseudo sole 10 in FIG. 3 taken along the line IV-IV.

  As shown in FIGS. 2 to 4, the pseudo sole 10 of the present embodiment includes a cotton material (cotton) 21 as a pseudo blood vessel element filled with pseudo blood, and the back side (back side) of the cotton material 21. Sponge material 22 as an elastic element for supporting In the present embodiment, a flat sponge material 22 having a thickness of about 5 mm is covered with a cotton material 21 having a thickness of about 5 mm. That is, the cotton material 21 covers not only the outer side (the back side of the foot) of the sponge material 22 but also the lateral side and the inner side of the sponge material 22. The sponge material 22 has a substantially oval shape with a major axis of 20 mm and a minor axis of 10 mm in plan view.

  The outer side of the cotton material 21 as a pseudo blood vessel element is covered with a pseudo skin layer 30. In the present embodiment, the pseudo skin layer 30 has a two-layer structure of an inner layer 31 and an outer silicon layer 32 as shown in FIG.

  As shown in FIG. 4, the outer silicon layer 32 constitutes the outermost layer of the pseudo sole 10 of the present embodiment, and is formed with a thickness of 1.2 mm to 1.5 mm by an air brush (a spraying process). The external silicon layer 32 is usually formed by using liquid silicon diluted with a solvent. In addition to the air brush, a brush or various brushes may be used. As shown in FIG. 4, the planned blood collection regions in the pseudo-plantar base 10 of the present embodiment are the L region and the R region on both sides of the buttock 11, and in these L region and R region, the inner layer 31 is not provided, and only the external silicon layer 32 is provided.

  On the other hand, in the heel part 11 and the lower ankle part 13, as shown in FIG. 4, an inner layer 31 shaped in a desired shape is provided in order to obtain a touch or texture similar to that of an actual sole or ankle. Yes. The inner layer 31 is generally formed from a silicon base material, like the outer silicon layer 32, but may be formed from other materials.

  In the present embodiment, the pseudo blood supply path 40 is formed so that the pseudo blood can be additionally filled into the cotton material 21 via the sponge material 22. Specifically, an area not covered with the cotton material 21 or the internal silicon layer 31 is provided as a circular hole portion above the sponge material 22, and the circular hole portion constitutes the pseudo blood supply path 40. A plastic coupling pipe (Luer joint) 52 communicating with the pseudo blood supply pipe 51 of the pseudo upper ankle 50 is inserted into the pseudo blood supply path 40 and coupled thereto.

  Next, the operation of the present embodiment configured as described above will be described.

  The practitioner grips the blood collection syringe needle with his hand, and grips the heel part 11 of the pseudo sole 10 according to the present embodiment with the hand opposite to the hand. Then, the injection needle is inserted into the planned blood collection region (R region or L region: see FIG. 4). When the injection needle is inserted to a depth of 1.2 mm to 1.5 mm, it reaches the cotton material 21 as a pseudo-vascular element. Then, due to the surface tension of the simulated blood, the simulated blood is sucked from the cotton material 21 toward the injection needle and collected. After a predetermined amount of blood is collected, the injection needle is withdrawn.

  Here, since the thickness of the central region of the heel part 11 is the same as that of the actual foot due to the presence of the inner layer 31, the trainee can obtain the same feel or texture as that of the actual sole. On the other hand, in the scheduled region for blood collection treatment, the thickness of the external silicon layer 32 as a pseudo skin layer is 1.2 to 1.5 mm, so the degree of simulation (simulation) of the blood collection treatment is also high.

  After the injection needle is extracted, it is preferable that the silicon tape is adhered or backfilled (adhered) with silicon cemedine in order to repair the hole of the injection needle. By such maintenance, the pseudo sole 10 according to the present embodiment can be used repeatedly to some extent.

  Here, it can be assumed that the cotton material 21 as a pseudo blood vessel element retreats to the back side due to repeated blood collection treatment training, but the inside of the cotton material 21 is elastically supported by the sponge material 22. Therefore, the load of the pressing force by the injection needle is effectively released. Therefore, even if the blood collection training is repeated, it is possible to prevent the cotton material 21 as the pseudo blood vessel element from moving backward or being unevenly distributed.

  When the pseudo blood filled in the cotton material 21 becomes insufficient due to the continuation of the blood sampling procedure, a pseudo blood supply device (not shown) is connected to the pseudo blood supply pipe 51 of the pseudo upper ankle 50, and the pseudo blood is appropriately simulated. Blood is replenished. The pseudo blood to be supplied reaches the cotton material 21 through the pseudo blood supply pipe 51, the coupling pipe 52, the pseudo blood supply path 40, and the sponge material 21.

  When some trouble occurs in the pseudo sole 10, the pseudo sole 10 can be easily detached from the pseudo upper ankle 50 as shown in FIG. 3 by folding the annular cover portion 14 downward. .

  As described above, according to the present embodiment, since the thickness of the central region of the heel part 11 is the same as that of the actual foot due to the presence of the inner layer 31, the trainee can feel the same feeling as that of the actual sole. Or you can get a texture. On the other hand, in the planned region for blood collection treatment, the thickness of the external silicon layer 32 as a pseudo skin layer is 1.2 to 1.5 mm, so that the degree of simulation (simulation) of the blood collection treatment is high.

  Moreover, since the inside of the cotton material 21 is elastically supported by the sponge material 22, the load of the pressing force by the injection needle is effectively released, and the cotton material 21 as the pseudo blood vessel element retreats to the back side. Or undesirably uneven distribution is suppressed.
