Japanese Utility Model Publication No. 63-60181

  However, the human body model for practicing prostate palpation has a prostate replacement mechanism in the space inside the main body, so the pressure applied to the finger inserted into the rectum during palpation practice is different from the actual one. There is a problem that the simulation level of training is inferior.

Moreover, since the structure is dedicated to the palpation practice of the prostate, there is a problem that palpation practice such as rectal cancer and wrinkles occurring in the rectum cannot be practiced.
The present invention has been made in view of these problems, and an object of the present invention is to provide a model for rectal palpation training with a high degree of simulation capable of palpating rectal cancer, rectal fistula or prostatic hypertrophy.

  In this column, in order to facilitate understanding of the invention, the reference numerals used in the “Mode for Carrying Out the Invention” column are attached as necessary, which means that the scope of claims is limited by this reference numeral. is not.

  The invention made in order to solve the problem described in “Problems to be Solved by the Invention” includes a simulated buttocks (10), a simulated rectum (20), a simulated lesion (30), and a simulated anus (40). Is a rectal palpation training model (1).

  The simulated buttocks (10) is made of a resin that simulates the buttocks of the human body and is provided with a hole (12) from the portion that hits the anus of the buttocks toward the inside. The simulated rectum (20) It is made of resin that simulates the rectum and is inserted into the hole (12) of the simulated buttock (10).

  The simulated lesion part (30) is provided on the inner wall surface of the simulated rectal part (20) and is made of resin harder than the simulated rectal part (20), which simulates the lesion of rectal cancer or vagina. 40) is formed in a substantially cylindrical shape, and is provided at one end of a resin-made insertion portion (42) to be inserted into the simulated rectal portion (20) and the insertion portion (42), from the outer diameter of the insertion portion (42). A resin-made exterior portion that is attached in close contact with the anus portion of the simulated heel portion (10) provided with a hole penetrating the hollow portion of the insertion portion (42) in a substantially disc-shaped central portion having a large outer diameter. (44).

  Such a model for rectal palpation training (1) is provided with a hole (12) from the anus to the inside of a resin-made simulated buttocks (10), and a simulated lesion (30) in the hole (12). A simulated rectal part (20) having Therefore, when the simulated rectal part (20) is inserted into the hole (12), the position of the simulated lesion part (30) can be arranged at an arbitrary position of the hole (12).

  That is, when it is desired to place the simulated lesion part (30) in a shallow position from the anus, the simulated lesion part (30) is disposed in the vicinity of the opening on the anal side of the simulated rectal part (20) and is to be located deep from the anus. In this case, the simulated lesion part (30) may be arranged at a position away from the anal opening.

  Further, when the simulated rectal part (20) is inserted into the hole (12), the simulated rectal part (20) is rotated with respect to the longitudinal axis of the rectum to thereby position the simulated lesion part (30). It can be set at any position in the circumferential direction of the anus.

Therefore, by making the hardness and shape of the simulated lesion part (30) approximate to rectal cancer and hemorrhoids, rectal cancer and hemorrhoids can be palpated.
Furthermore, since the simulated heel part (10) is made of resin, when the finger is inserted into the hole (12) by making the hardness close to that of the human body, pressure is applied from around the finger, Since the finger can be given a feeling of pressure similar to that during actual palpation, the degree of simulation of palpation training is improved.

  In addition, as described in claim 2, the inside of the simulated heel part (10) is in contact with the outside of the simulated rectal part (20), and the front side of the human body is a substantially rectangular parallelepiped on the side of the simulated rectal part (20). If the surface is provided with a simulated prostate part (50) made of a resin harder than the simulated rectal part (20) having a recess in the longitudinal direction of the simulated rectal part (20), palpation of the prostate is also possible.

Therefore, if the hardness and size of the simulated prostate part (50) are approximated to a state where the prostate is enlarged, palpation training for prostate enlargement is also possible.
By the way, various resins can be considered as the resin for forming the simulated collar portion (10). However, when the urethane gel material is used as described in claim 3, the hardness or the tactile sensation or the internal hole portion (12) Since the feeling of pressure applied to the finger when the finger is inserted becomes close to the actual feeling, the simulation level of the palpation training can be improved.

  In addition, if the resin forming the simulated anus (40) is a silicone resin as described in claim 4, when the finger is inserted into the simulated rectum (20) in the palpation training, Since pressure similar to that of the anus is applied to the finger, the simulation of palpation training can be improved.

  Furthermore, if the resin forming the simulated rectal portion (20) is a styrenic elastomer resin as described in claim 5, when a finger is inserted by palpation training, the hardness of the inner wall of the actual rectum is very close. Since a tactile sensation is obtained, the simulation level of the palpation training can be improved.

It is a figure which shows the schematic structure of the model for rectal palpation training. It is sectional drawing of a simulation rectal part. It is a figure which shows the general | schematic structure of a simulated anal part.

  Embodiments to which the present invention is applied will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.

FIG. 1 is a diagram showing a schematic configuration of a model 1 for rectal palpation training to which the present invention is applied.
As shown in FIG. 1, the rectal palpation training model 1 includes a simulated buttocks 10, a simulated rectum 20, a simulated lesion 30, a simulated anus 40, and a simulated prostate 50.

  The simulated heel part 10 simulates the buttock of a human body, and is formed by molding a urethane gel material colored in skin color into a buttock shape. A hole 12 having a diameter of about 20 [mm] is provided from the portion of the buttocks that contacts the anus to the inside.

The path of the hole 12 in the simulated buttocks 10 is the same path as the rectum from the portion that hits the anus to the actual human body toward the inside of the simulated buttocks 20.
The simulated rectal portion 20 simulates the human rectum, is formed of a styrene-based elastomer resin, and is used by being inserted into the hole 12 of the simulated collar portion 10. The simulated rectal portion 20 is formed by forming a styrenic elastomer resin into a bellows-like cylindrical shape like an actual rectal inner wall surface.

  Further, a simulated lesion part 30 is attached to the inner wall surface of the simulated rectal part 20 as shown in FIG. This simulated lesion part 30 simulates the lesion of rectal cancer or hemorrhoids, and a resin (for example, rubber) harder than the simulated rectal part 20 is shaped into a substantially spherical shape and bonded as shown in FIG. It is adhered to the inner wall surface of the simulated rectal portion 20 with an agent.

  As shown in FIG. 3, the simulated anal part 40 includes an insertion part 42 and an exterior part 44. The insertion part 42 is formed of a substantially cylindrical resin so that it can be inserted into the end of the simulated rectal part 20.

  In addition, an exterior portion 44 is provided at one end of the insertion portion 42 (an end portion opposite to the inserted end portion). The exterior portion 44 is formed of silicon resin in a substantially disk shape, and has an outer diameter larger than the outer diameter of the insertion portion 42, and a hole penetrating the hollow portion of the insertion portion 42 is provided in the central portion. It has been.

  As shown in FIG. 1, the simulated prostate part 50 is provided inside the simulated heel part 10 and is formed by molding a resin (for example, rubber) harder than the simulated rectal part 20 into a substantially rectangular parallelepiped shape. The simulated prostate part 50 is disposed on the front side of the simulated buttocks 10 (on the opposite side of the anus) and in contact with the outside of the simulated rectal part 20.

Further, the surface in contact with the simulated rectal portion 20 is shaped so as to have a recess in the longitudinal direction of the simulated rectal portion 20.
(Characteristics of model 1 for rectal palpation training)
In the rectal palpation training model 1 as described above, the simulated rectal portion 20 having the simulated lesion portion 30 is inserted into the hole 12 provided inside from the anus of the simulated heel portion 10 made of urethane gel.

  Therefore, when it is desired to place the simulated lesion portion 30 in a shallow position from the anus, the simulated lesion portion 30 is disposed in the vicinity of the opening on the anal side of the simulated rectal portion 20, and when it is desired to be located deep from the anus, the simulated lesion portion. By disposing 30 at a position away from the anal opening, the simulated lesion 30 can be disposed at an arbitrary position in the depth direction.

  Further, when the simulated rectal part 20 is inserted into the hole 12, the simulated rectal part 20 is rotated with respect to the longitudinal axis of the rectum, so that the position of the simulated lesion part 30 is arbitrarily set in the circumferential direction of the anus. Can be set to position. Therefore, by making the hardness and shape of the simulated lesion portion 30 approximate to rectal cancer and hemorrhoids, rectal cancer and hemorrhoids can be palpated.

  Furthermore, since the simulated heel part 10 is formed of a urethane gel material, the hardness, tactile sensation, or the feeling of pressure applied to the finger when the finger is inserted into the internal hole part 12 is close to actual. Therefore, the simulation degree of palpation training can be improved.

  Moreover, since the simulated anal part 40 is formed of silicone resin, when a finger is inserted into the simulated rectal part 20 during palpation training, pressure similar to that of the actual anus is applied to the finger due to the elasticity of the silicone resin. Training simulation can be improved.

  Furthermore, since the simulated rectal portion 20 is formed of a styrene-based elastomer resin, when a finger is inserted during palpation training, hardness and touch that are very close to the actual inner wall surface of the rectum can be obtained. Can be improved.

Moreover, since the simulated prostate part 50 is provided, if the hardness and size of the simulated prostate part 50 are approximated to a state in which the prostate is enlarged, palpation training of the enlarged prostate can be performed.
