Problems solved by technology

However, the existing technology device is a gravity self-flowing type, and the blood pressure and blood flow velocity change with the height of the blood bag, and, with the increase of the bleeding volume, the bleeding pressure and flow velocity will change, which is not enough to simulate the real blood pressure and bleeding of the human body. scene, and not scientific and rigorous
Most of the artificial blood that flows out will be lost every time, which not only pollutes the environment, but fails to meet the requirements of quantification and refinement

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0030] Such as figure 1 and figure 2 As shown, a teaching device for simulating human arterial ligation includes a test bench 1, a simulated blood vessel 2, a simulated blood storage tank 3, a pressurizing device 8 and a simulated blood recovery tank 4;

[0031] A cofferdam is set on the test bench 1, and several simulated blood vessels 2 are arranged in the cofferdam. The simulated blood vessels 2 are connected to the simulated blood storage tank 3, and the pressurizing device 8 is connected to the simulated blood storage tank 3. The pressurizing device 8 is used for Provide stable simulated human body pressure for the simulated blood storage tank 3 .

[0032] An operation platform 101 is arranged in the cofferdam of the test platform 1, and a blood-containing chamber 102 is arranged unde...

Abstract

The invention discloses a teaching device used for simulating ligation of an artery blood vessel of a human body, and belongs to the technical field of medical simulation teaching devices. The teaching device comprises a test bed, simulated blood vessels, a simulated blood storage tank and a pressurization device, wherein a cofferdam is arranged on the test bed; a plurality of simulated blood vessels are arranged in the cofferdam; the simulated blood vessels are connected with the simulated blood storage tank; and the pressurization device is connected with the simulated blood storage tank. The pressurization device is used for supplying stable pressure of a simulated human body to the simulated blood storage tank, so that the problem of a gravitational flow type device in the prior art that the bleeding pressure and the flow velocity change due to the increase of the amount of bleeding as the blood pressure and the blood flow velocity change with the height of a blood bag is solved, so that the simulation test teaching is closer to an actual situation, and an effect of simulation teaching is improved.

Description

technical field [0001] The invention relates to the technical field of medical simulation teaching devices, in particular to a device for simulating human artery ligation. Background technique [0002] Clinical practice is an important part of training qualified medical students and an important part of clinical teaching. With the progress of society, the gradual improvement of the rule of law and the enhancement of patients' self-protection awareness, the traditional medical education system and clinical practice teaching are facing more and more difficulties and challenges. Traditional clinical practice directly targeting patients The teaching mode is facing a severe test. The traditional practice teaching mode can no longer meet the requirements of modern medical education for the training of medical students' clinical skills. Simulated medicine is a new model of clinical skills teaching. Applying simulated medicine to practice teaching can help trainees master practical...
