Description
Technical Field
The utility model relates to a medical science teaching mode, especially a teaching mode that is used for palpation to judge chest and abdomen varicosity blood flow direction.
Background
Clinically, three diseases can cause vein backflow obstruction to cause varicose veins on the thoracoabdominal wall, and the blood flow direction in varicose veins caused by each disease is different. The blood flow direction of the varicose vein is judged by a sliding palpation method, and the disease can be preliminarily diagnosed.
In clinical practice, as the self-protection consciousness of patients is enhanced, some patients do not want to cooperate with medical students to carry out physical examination, and the condition brings difficulty to medical teaching.
Disclosure of Invention
The utility model provides a can solve the technical insufficiency, can be used to supply medical colleges and universities and each relevant professional student and clinical intern to study and practise in clinical teaching, can relative objective simulation reflect the teaching model of chest abdomen wall varicosity blood flow direction.
The utility model discloses a chest abdomen varicosity palpation inspection model makes vacant shell form model inner core with stereoplasm macromolecular material, the intermediate layer of the outer cladding one deck soft macromolecular material of relative of vacant shell form model inner core, again the outer cladding of intermediate layer with the macromolecular material of texture similar skin, the simulation superior vena cava that the corresponding position of intermediate layer respectively set up the hose and made is blocked varicose vein that causes, the varicose vein that the inferior vena cava blocked and the varicose vein that the portal vein was blocked and is caused, the first of simulation vein, end communicate a corresponding input and the output that can open respectively and close the pump separately respectively, and set up corresponding stock solution container at the input end department of each pump, are filled with working medium in the stock solution container.
Preferably, the utility model discloses a chest abdominal varices palpation inspection model, its inner core material is polyethylene, sandwich material be polyurethane, the epidermis material be crystallization type saturated polyester PET, the hose be the emulsion tube, used pump is the peristaltic pump.
Preferably, the utility model discloses a chest abdomen varicosity palpation inspection model, its stock solution container be the stock solution bag.
More preferably, the skin material used in the model for palpation of varicose veins in chest and abdomen of the present invention is polyethylene terephthalate.
The utility model discloses during the use, can make corresponding simulation vein be full of liquid and directional flow after the peristaltic pump starts, produce the sense of touch and be very close with the sense of touch of true human varicose vein outside the epidermis, judge varicose intravenous blood flow direction through the sliding touch method to relevant disease of preliminary diagnosis, consequently can supply each relevant professional student of medical colleges and universities and clinical practice student to practise.
Drawings
Fig. 1 is a schematic view of the main viewing position of the present invention. Fig. 2 is a schematic cross-sectional view at two centimeters above the umbilicus of fig. 1, and fig. 3 is a schematic cross-sectional view at two centimeters below the umbilicus of fig. 1. FIG. 4 is a schematic view of the communication lines between each vein and each corresponding infusion pump and reservoir. In the figure: 1 and 4 are respectively the position of an abdominal wall varicose vein when inferior vena cava is obstructed, 2 and 3 are respectively the position of an abdominal wall varicose vein when superior vena cava is obstructed, 5 is the position of an abdominal wall varicose vein when hepatic portal vein is obstructed, 6 is a skin material, 7 is an interlayer material, 8 is a model core, 9 is a pipeline for communicating the abdominal wall varicose vein caused by inferior vena cava obstruction with a inferior vena cava high-pressure pump and a inferior vena cava liquid storage container, 10 is a pipeline for communicating the abdominal wall varicose vein caused by superior vena cava obstruction with a superior vena cava high-pressure pump and a superior vena liquid storage container, 11 is a superior vena cava high-pressure pump, 12 is a superior vena cava liquid storage container, 13 is a hepatic portal vein high-pressure pump, 14 is a hepatic portal vein liquid storage container, 15 is a inferior vena cava high-pressure pump, 16 is a inferior vena liquid storage container, and 17 is a pipeline for communicating the abdominal wall varicose.
Detailed Description
The attached drawings are embodiments of the invention. Referring to fig. 1, it can be seen that the present invention presents an appearance model of human trunk, and in fig. 1, the positions of varicose veins 1 and 4 due to inferior vena cava obstruction, varicose veins 2 and 3 due to superior vena cava obstruction, and varicose vein 5 due to hepatic portal vein obstruction (four in total, see fig. 1) are indicated by dotted lines. From fig. 2 of the cross-sectional view of 2 cm above the umbilicus of fig. 1 and fig. 3 of the cross-sectional view of 2 cm below the umbilicus of fig. 1, it can be seen that the cross-sectional structure of the present invention, the points marked in the cross-section of the veins in fig. 2 and 3 are the blood outflow direction and the marked forks are the blood inflow direction. As can be seen from fig. 2 and 3, the utility model discloses a model core 8 of human trunk shape of empty shell form made of polyethylene material, the intermediate layer 7 of polyurethane is coated on the periphery of empty shell form model core 8, and then latex tubes 1, 2, 3, 4 and 5 are arranged at the corresponding positions of intermediate layer 7 to simulate corresponding varicose veins, and simultaneously the head and the tail both ends of these simulated varicose veins are respectively communicated with peristaltic pumps 11, 13 and 15 by additional hoses, such as communicating tubes 9, 10 and 17 shown in fig. 4, and liquid storage containers 12, 14 and 16 composed of liquid storage bags are respectively arranged at the upstream of each peristaltic pump. It should be noted that the way in which varicose veins due to obstruction of the superior vena cava and those due to the inferior vena cava, and those due to obstruction of the hepatic portal vein and the connection to the respective pumps should be as shown in fig. 4. A skin material 6 of polyethylene terephthalate is coated outside the interlayer 7.
The utility model discloses open corresponding peristaltic pump respectively when using and can make full liquid and directional flow in the corresponding venous emulsion tube of simulation, at this moment from outside the epidermis material 6, can judge the blood flow direction through the slip palpation method to the disease is suffered from in preliminary diagnosis. Thus realizing and completing the functions of clinical learning, practice and practice.
