Description

Artificial blood vessel surgery teaching aids

The present invention relates to a teaching aid for medical clinical simulation operation, and in particular to a teaching aid for artificial blood vessel surgery that allows clinical nursing personnel to easily understand and become familiar with the structure of artificial blood vessels and further become proficient in the curved needle placement technique.

According to the information, the placement of artificial blood vessels is one of the necessary ways for cancer patients to receive chemotherapy. In terms of its design concept, it is mainly to allow artificial blood vessels to be placed in the patient's body for a long time, so that medical staff can directly provide chemotherapy drugs to the patient through the artificial blood vessels. This type of artificial blood vessel placement allows cancer patients to avoid the need for indwelling soft needles or other tubes like general patients. In other words, patients with artificial blood vessels do not need to regularly replace indwelling soft needles and related tubes.

However, when cancer patients have artificial blood vessels installed for chemotherapy, medical staff mainly use curved needles to insert them into the artificial blood vessels, and then inject chemotherapy drugs into the artificial blood vessels through the curved needles, and then allow the chemotherapy drugs to flow from the artificial blood vessels into the connected human blood vessels, so that the chemotherapy drugs flowing into the cancer patient's blood vessels can treat the cancer patient. However, during the treatment process, cancer patients will also be killed by chemotherapy drugs because their immunity is reduced. Therefore, cancer patients are more likely to be infected by other pathogens due to decreased immunity. Among the causes of infection, improper placement or operation of curved needles by medical staff is the main cause.

Furthermore, 3D printing technology is gradually becoming more popular. Therefore, how to use 3D printing technology to print a chest and neck similar to the patient and implant an artificial blood vessel into the printed chest and neck, so that new medical personnel can understand how to correctly operate the curved needle so that the curved needle can be easily placed in the artificial blood vessel and artificial blood can be injected, so the previous technology really needs to be improved.

The artificial skin layer 30, please refer to FIG. 3 and FIG. 4 again. The artificial skin layer 30 covers the outer surface of the main body unit 11 and the first surface 231 of the replaceable operating platform 20 assembled on the main body unit 11, and the artificial skin layer 30 is provided with a plurality of second connection units 31 at positions relative to the first connection units 15. The second connection units 31 can be respectively assembled with one of the corresponding first connection units 15. The artificial skin layer 30 can be a transparent silicone unit, a non-transparent silicone unit, or a silicone unit with different thicknesses according to needs, so that the artificial skin layer 30 can simulate the subcutaneous tissue of real human skin;

The processing unit 40 is accommodated in the accommodation space 12 and is electrically connected to the sensing unit 213 and the warning unit 16, respectively, so as to receive and process the signal transmitted by the sensing unit 213 electrically connected thereto, and control the warning unit 16 electrically connected thereto to generate a warning light signal. The processing unit 40 of this embodiment controls the indicator lights 161 of the warning unit 16 to generate a warning light signal;

In which, the artificial skin layer 30 is adjacent to the artificial blood vessel module 21, and the first surface 231 is located between the artificial skin layer 30 and the artificial blood vessel module 21, and a first thickness D1 of the silicone layer 23 between the artificial blood vessel module 21 and the second surface 232 is greater than a second thickness D2 of the silicone layer 23 between the artificial blood vessel module 21 and the first surface 231, and the injection tube diameter R1 is greater than the liquid storage tube diameter R2, and the injection volume W1 is greater than the liquid storage volume W2.

The artificial skin layer 30 covers the artificial blood vessel module 21. Therefore, when clinical medical staff need to observe how the curved needle 210 enters the artificial blood vessel module 21, the artificial skin layer 30 can be selected to be a transparent silicone unit. After becoming familiar with the operation, the artificial skin layer 30 can be changed to a non-transparent silicone unit.

Please refer to Figure 5 again, which is the artificial blood vessel surgery teaching aid 100 of another embodiment of the present invention. Its main structure is roughly the same as the above-mentioned embodiment and will not be repeated here. The main difference is that the replaceable operating platform 20 is provided with a universal rotation unit 50 and a base unit 60 assembled in the accommodating space 12, and the universal rotation unit 50 includes a fixer 51 and a pivot rod 52, one end of the fixer 51 is assembled on the base unit 60, and one end of the pivot rod 52 is pivotally connected to the fixer 51, and the other end of the pivot rod 52 is pivotally connected to the artificial blood vessel module 21.

Please refer to FIG. 1 to FIG. 4. After the human body simulator 10 selects the appropriate replaceable operation platform 20 according to the needs, the second buckle unit 22 is assembled on the first buckle unit 14, so that the replaceable operation platform 20 can be accommodated in the coupling hole 13. At this time, the second connecting units 31 of the artificial skin layer 30 are attached to the corresponding first connecting units 15. The first connecting units 15 and the second connecting units 31 of this embodiment are the male and female parts of Velcro, but not limited to this. The connecting tube 211 is combined with the artificial blood vessel module 21 and the liquid storage unit 212. In this way, the user can inject the liquid through the injection unit. The artificial blood vessel module 21 can be placed at different positions of the silicone layer 23 and the first thickness D1 can be different from the second thickness D2. In this way, the artificial blood vessel module 21 can be placed at various positions or at various inclinations at the chest wall when implanted in the chest wall of different cancer patients. Please refer to FIG. 5 for another embodiment of the replaceable operating platform 20. The artificial blood vessel module 21 can be used to simulate the possible inclination of the artificial blood vessel module 21 at different chest wall positions when the artificial blood vessel module 21 is implanted in the chest wall of different cancer patients. Furthermore, although the artificial blood vessel module 21 is covered by the silicone layer 23, the artificial blood vessel module 21 is adjacent to the artificial skin layer 30, and does not directly contact the artificial skin layer 30 covering the outer side of the silicone layer 23. Therefore, the thickness of the silicone layer 23 between the artificial skin layer 30 located at the non-artificial blood vessel module 21 and the artificial skin layer 30 located at the artificial blood vessel module 21 is different, so the medical staff can adjust the inclination of the artificial blood vessel module 21 at different chest wall positions. The personnel can thereby first determine the location of the artificial blood vessel module 21 at the silicone layer 23, and insert the curved needle 210 through the artificial skin layer 30 into the artificial blood vessel module 21 for injection. The sensing unit 213 connected to the artificial blood vessel module 21 will sense whether the curved needle 210 is correctly inserted into the artificial blood vessel module 21 for injection. If the sensing unit 213 senses that the curved needle 210 is not correctly inserted, the sensing unit 213 will send a signal back to the processing unit 40, and the processing unit 40 will generate one of the warning signals such as a warning light or a warning sound through the indicator lights 161 of the warning unit 16 to remind the operating medical staff.

In addition, please refer to Figures 2 to 3. When the injection unit 200 injects the artificial blood vessel module 21 through the curved needle 210, since the artificial blood vessel module 21 is composed of the connecting tube 211 and the liquid storage unit 212, the liquid storage unit 212 can store the liquid injected into the artificial blood vessel module 21 by the injection unit 200 during the simulated injection. Furthermore, the injection tube diameter R1 and the injection volume W1 of the injection unit 200 are larger than the liquid storage tube diameter R2 and the liquid storage volume W2 of the liquid storage unit 212. Therefore, after the simulated injection, the liquid stored in the liquid storage unit 212 can be drawn back to the injection unit 200 through the injection unit 200.

In summary, the artificial blood vessel surgery teaching aid 100 of the present invention uses 3D printing technology to print a chest and neck model of a cancer patient as the human body simulator 10, and the main body unit 11 of the human body simulator 10 is provided with the coupling hole 13, and the replaceable operating platform 20 equipped with the artificial blood vessel module 21 is set through the coupling hole 13, and the main body unit 11 and the assembled The outer side of the replaceable operation platform 20 can be covered with the artificial skin layer 30 of appropriate color and thickness corresponding to the condition of the simulated cancer patient, and the artificial skin layer 30 is completely covered on the artificial blood vessel module 21, so that the artificial blood vessel module 21 is adjacent to the artificial skin layer 30, and the silicone layer 23 is located between the artificial blood vessel module 21 and the second surface 232. The thickness D1 is greater than the second thickness D2 of the silicone layer 23 between the artificial blood vessel module 21 and the first surface 231. Furthermore, the medical staff in training can also replace the replaceable operating platform 20 so that the replaceable operating platform 20 can simulate the state of the artificial blood vessel module 21 being located at different positions of the silicone layer 23. Further, the medical staff can practice the artificial blood vessel module 21. When the distance from the first surface 231 is different or the inclination angle is different, how the medical staff inserts the curved needle 210 into the artificial blood vessel module 21, so that the artificial blood vessel surgery teaching aid 100 not only allows the relevant medical staff to have relevant teaching aids for practice, but also can reduce the probability of various infections that may be caused to patients by improper operation during the real operation process, thereby improving the quality of patient care.
