Figure 4 is a side view showing the stretching state sequentially, Figure 4 (a) (b) is a reference diagram showing the operating state of the needle penetrating part in the practice terminal device for the virtual vein injection learner proposed as a preferred embodiment in the present invention to be.

Training terminal device 1 proposed in the preferred embodiment of the present invention, as shown in Figure 1 is to drive the application stored in the database to display the body part of the virtual model on the screen 110 to find the vein And connected to the well-known virtual intravenous injection learner 100 to let the learner to learn how to place and intravenous injection, the learner in conjunction with the application running on the most intravenous injection learner 100 through the control unit 40 It is a peripheral device for a kind of virtual intravenous learner 100 to realistically learn how to give an injection.

The virtual intravenous injection learner 100 displays the body of the virtual model through the screen 110 so that the learner retrieves the position of the vein requiring needle penetration of the injection through a peripheral device such as a mouse or a keyboard. It is a known learner configured to virtually place an intravenous infusion into the retrieved vein by selecting the intravenous to be displayed on.

Meanwhile, as shown in FIG. 2, the training terminal 1 according to the present exemplary embodiment generates an input signal by a physical contact of a learner through the touch pad 21 and applies it to the virtual intravenous injection learner 100 to display a screen ( A touch pad input unit 20 for searching for and designating a vein among body parts of the virtual model displayed on 110; The needle penetrating part 30 forming the transmission path of the needle 51 is formed in the main body 10, and the touch pad input part 20 and the needle penetrating part 30 are controlled. 40 is driven in conjunction with the above-described intravenous injection learner 100.

Therefore, when a learner places a finger on the touch pad 21 of the touch pad input unit 20 provided in the training terminal device 1 and moves it to the left or right, the virtual displayed on the screen 110 of the virtual vein injection learner 100 is displayed. Veins are searched and designated in the body part of the model, and this description is similar to the known description implemented through a mouse or keyboard.

However, in the present embodiment, when implementing the practice terminal device 1, when the vein is searched through the contact with the touch pad 21, the learner can recognize the shape and pulse of the vein not only through vision but also through tactile sense. It is configured so that more realistic learning is made, and this is regarded as the technical gist of the present application.

To this end, in this embodiment, as shown in Figure 3, the tube member 22 made of an elastic material on the bottom surface of the touch pad 21 for searching the vein of the virtual model displayed on the screen 110 by the learner's body contact ) And an operating pump (23) for controlling the injection of the working fluid (24) in the tube member (22).

Here, referring to the drawing, the operation pump 23 has a form in which a piston 23b connected to the retraction rod 23c is installed in the cylinder 23a in which the working fluid 24 is filled, and is installed. The working fluid 24 filled in the cylinder 23a is injected into the tube member 22 when the forward and backward rod 23c moves forward by the control of. The working fluid 24 injected into) is made to be refilled into the cylinder (23a).

Here, the retraction rod 23c for the retraction action of the piston 23b provided in the operation pump 23 is a solenoid type that retreats by the electromagnetic force and a pneumatic cylinder type that retreats by the injection of air, respectively. Can be adopted.

With this configuration, when the learner contacts the finger on the touch pad 21 and searches for veins in the body of the virtual model displayed on the screen 110, the controller 40 moves forward and backward 23c of the operation pump 23. By injecting the working fluid 24 into the contracted tube member 22 and expanding it, the learner who placed the finger on the touch pad 21 recognizes through the tactile sense that the current searched position is the point where the vein is located. Do it.

That is, in the state where the vein is not detected, the learner makes a flat state even if the touchpad 21 is placed with the finger. However, when the vein is searched, the touchpad 21 protrudes linearly by the expanded tube member 22. In this way, the learner can recognize through touch that the current searched position is the point where the vein is located.

In addition, the control unit 40 repeatedly retreats the retraction rod 23c of the operation pump 23, and injects and discharges a small amount of the working fluid from the tube member 22 to contract and expand the tube member 22. This is repeated.

As described above, when the contraction and expansion of the tube member 22 are repeated, the learner who recognizes the shape change of the tube member 22 by placing a finger on the touch pad 21 may learn about the contraction and expansion of the tube member 22. Since the pulse of the vein is perceived through tactile, more realistic learning can be achieved.

In this way, the learner who has learned the vein detection process through the touch pad input unit 20 learns the technique of transmitting the needle 51 of the intravenous injection 50 to the detected vein through the needle penetrating unit 30. .

The needle penetrating portion 30, as shown in Figure 4, the through hole 31 formed to penetrate the main body 10, and the resistance bundle 32 is installed in the lower portion of the through hole 31; And a measurement sensor 33 for measuring the depth of entry of the needle 51 through the penetrating hole 31 and entering the needle 51. The resistance is variable so that the learner can virtually experience that the intravenous needle passes through the epidermis, muscle layer and blood vessel layer of the human body in sequence.

According to the present embodiment, the resistance bundle 32 has a structure in which three support members 32a are disposed in a radial structure, and each of the support members 32a is provided with a retraction rod 32b, where the retreat is provided. The rod 32b may adopt a solenoid type, in which a retracting action is made by an electromagnetic force, or a pneumatic cylinder type, which is retracted by injecting air, as in the retracting rod of the operation pump 23. The advance and exit rod 32b and the measurement sensor 33 are driven by the control of the control unit 40.

Therefore, when the control unit 40 advances the retraction rod 32b, the adhesion between the respective support members 32a is increased, and conversely, when the retraction rod 32b is retracted, the adhesion between the support members 32a is decreased. When the learner passes the intravenous needle 51 through the penetrating hole 31, the measurement sensor 33 measures the entry depth of the intravenous needle 51.

At this time, the control unit 40, the advancing rod (32b) of the resistance bundle 32 is variably advancing in accordance with the entry depth of the intravenous injection needle 51 entering through the measurement sensor 33 between the support member (32a) Will increase or decrease the adhesion.

Thus, since the frictional resistance value of the intravenous injection needle 51 entered between the support members 32a of the resistance bundle 32 through the penetration hole 31 is changed according to the depth of entry, the learner is like an intravenous injection needle. Similar to 51 being able to sequentially penetrate the epidermis, muscle layer and blood vessel layer of the human body.
