Abstract

PROBLEM TO BE SOLVED: To enable a learner to remember a correct injection position while relating it with human body tissues by providing an outward appearance part that simulates the outward appearance of one of the right and left side of the human body and can get injections and a tissue part simulating the internal tissues of the other side part symmetrical with part of the human body. SOLUTION: The injection simulator 1 consists of the outward appearance part 2 which simulates the outward appearance of the left buttock part of the human body and the tissue part 3 which simulates the internal tissues of the right buttock part, and the outward appearance part 2 and tissue part 3 are united. The tissue part 3 is protected by transparent hard plastic 11 which is so molded as to resemble the outward appearance of the right buttock part, and models 12 for internal tissues such as the inner buttock muscles, nerves, blood vessels, etc., of the pelves are fixed in it. A practicer examines the outward appearance 2 by touch and sees the tissues models 12 in the tissue part 3 to select a correct injection position by contrast with the human body tissues, thereby sticking an injection needle in the outward appearance part 2. When an injection is given at the correct position, injected liquid is discharged to a waste liquid bag 9 through a waste liquid tube 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an injection simulator.

2. Description of the Related Art A model of a muscular part has conventionally been used as a target for nursing students and medical students to practice muscle injection. The conventional model is, for example, utility model registration No. 303204.
As described in Japanese Patent Application Publication No. 9-29, it is composed of a muscle simulated body made of gel or foamed resin and imitating a muscle, a pair of conductive sheets arranged in an upper layer of the muscle simulated body, and an outer bag wrapping the whole. When the needle is stabbed at the correct site, the conductive sheets remain insulated from each other, but when stabbed at the wrong site, the conductive sheet is short-circuited by the needle and a signal is sent to the notification circuit. Notified by lamp or buzzer.

[0002]

However, with the conventional model, students cannot learn the correct injection site in association with the human body tissue, and the student has no choice but to learn the correct injection site blindly. Therefore, they cannot acquire applied skills. Alternatively, it is necessary to use a specialized book that describes the structure of the human body and learn at a different time and place from the learning using the model. Therefore, it is difficult to combine the injection site learned by the model with the injection site learned in the technical book in the head. Therefore, an object of the present invention is to provide an injection simulator that can simultaneously perform an injection training on the spot while learning a human body tissue.

[0003]

In order to achieve the object, an injection simulator according to the present invention is a simulator for learning a site to be injected into a human body, which has an appearance part and a tissue part. The appearance part is an injectable part that imitates the appearance of a part of one of the right and left sides of the human body. The organization department
It simulates the internal structure of the part on the other side symmetrically located with a part of the human body. Since the external part and the tissue part of the above configuration are paired, it is possible to inject the external part while checking the correct injection site by looking at the tissue part.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the injection simulator of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an injection simulator, and FIG. 2 is a vertical cross-sectional view of an appearance portion thereof. The injection simulator 1 has an appearance part 2 simulating the appearance of the left hip of the human body and a tissue part 3 simulating the internal tissue of the right hip.
And the appearance part 2 and the tissue part 3 are integrated.

[0005] The exterior part 2 is covered with a rubber-made skin 4 whose skin color is similar to the skin of a human body. The skin 4 is filled with an elastic material 5 such as a foamed resin. It is implanted, and the palpable muscle injection site can be confirmed by palpation. A space 7 for receiving the injection liquid is provided in a liquid-tight manner inside the correct injection range of the epidermis 4, and this space 7 is connected to an external drain bag 9 via a drain tube 8.
Is in communication with Immediately below the epidermis 4, a pair of conductive sheets 10 are fixed except for the correct injection range.

[0006] The tissue portion 3 is protected by a transparent hard plastic 11 molded so as to approximate the outer shape of the right hip, in which a model 12 of internal tissue such as the pelvic midgluteal muscle, nerves, blood vessels and the like is placed. Fixed.

To practice injection using the injection simulator 1, the power switch 13 is turned on and a voltage is applied between the conductive sheets 10 from the battery 14 in advance.
The trainee palpates the external part 2 and looks at the tissue model 12 in the tissue part 3 to select a correct injection site while comparing it with human tissue, and pierces the external part 2 with an injection needle. When the injection is made at the correct site, the injected injection solution is discharged into the drainage bag through the drainage tube 8. The drain bag is replaced when it is full. On the other hand, if injected into the wrong site,
The conductive sheets 10 are short-circuited to each other, a current flows by the voltage applied from the battery 14, and the buzzer 15 sounds and the lamp 16 is turned on at the same time.

Although the embodiment shown in the drawings is for injecting the buttocks muscle, the present invention is not limited to this, and the present invention is not limited to this. The present invention can also be applied to intravenous injections having an appearance part and a tissue part which respectively imitate. Also, in the case of the above-mentioned buttocks muscle injection simulator, since the right and left buttocks of the human body are in close contact,
In the injection simulator, the external part and the tissue part were directly integrated, but in the case of the upper arm muscle injection simulator or the intravenous injection simulator, it is practical to fix the external part and the tissue part through a model of the chest or torso. Is good.

[0009]

As described above, according to the present invention, the injection training can be performed on the spot while the human body tissue and the correct injection site are three-dimensionally compared, so that the learner can associate with the human body tissue. You can remember the correct injection site.
