Example

[0023] example 1

[0024] See Figure 1 ~ Figure 3 The blood flow simulation device of this embodiment is a closed circulating liquid flow system consisting of a liquid storage tank 1, a peristaltic pump 2, a one-way valve 3, a simulation chamber 4, and a back pressure valve 13 connected end to end through pipes, in which, A pressure gauge 5 is arranged between the one-way valve 3 and the simulation chamber 4. The simulation chamber 4 is composed of a simulated blood vessel 4-1 and an annular dissection balloon 4-8 tightly sleeved outside the simulated blood vessel 4-1, wherein the outer wall of the inner layer of the annular dissection balloon 4-8 is on both sides of the outer wall. The inner wall extends a longitudinal partition 4-5, which divides the annular space in the annular sandwich airbag into two upper and lower air chambers 4-2. Each air chamber 4-2 is provided with an air inlet 4-3 and an air outlet 4-4, where each air inlet 4-3 is connected to the outlet of the air...

[0025] Example 2

[0026] See Figure 5 The difference between this embodiment and Example 1 is that the simulated cavity consists of a simulated blood vessel 4-1 and two annular dissection balloons 4-8 tightly sleeved outside the simulated blood vessel 4-1. The simulated blood vessel 4-1 is made of elastic fiber material. Manufactured, the annular sandwich airbag 4-8 is made of polypropylene film (PP) material.

[0027] In this example, the implementation methods other than the above are the same as in Example 1.

Example

[0028] Example 3

[0029] See Image 6 The difference between this embodiment and Examples 1 and 2 is that the simulated blood vessel 4-1 is made of rubber material, the annular sandwich balloon 4-8 is made of polyvinyl chloride film (PVC) material; the annular sandwich balloon 4 8 Two layers of transverse partitions 4-6 extend from the outer wall of the inner layer to the inner wall of the outer layer, and divide the air chamber 4-2 into three sections along the axial direction.

[0030] In this example, the implementation methods other than the above are the same as in Example 1.

Abstract

The invention discloses a blood flow simulation device. The device is a closed-loop liquid flow system consisting of a liquid storage tank (1), a peristaltic pump (2), a simulation chamber (4) and a back pressure valve (13) which are sequentially connected end to end through a pipeline, and is characterized in that: the simulation chamber (4) consists of a simulation blood vessel (4-1) and at least one annular interlayer air bag (4-8) tightly sleeved outside the simulation blood vessel (4-1), wherein the two sides of an outer wall of an inner layer of each annular interlayer air bag (4-8) respectively extend to an inner wall of an outer layer to form a longitudinal interlayer (4-5) which divides an annular space in each annular interlayer air bag into two air chambers (4-2); each air chamber (4-2) is respectively connected with the outlet of an air feed pump (8) and the inlet of a vacuum pump (9) through a two-position two-way electromagnetic valve (6); and the simulation blood vessel(4-1) is made of an elastic material and the air bags (4-8) are made of thin film materials. The blood flow simulation device can simulate the blood flow condition when a blood vessel is expanded andcontracted and pressed.

Description

technical field [0001] The invention relates to a medical experiment device, in particular to a blood flow simulation device. Background technique [0002] Cardiovascular disease is a serious threat to human health. The number of people who die from cardiovascular disease is as high as 15 million every year in the world. In my country, the number of deaths caused by cardiovascular and cerebrovascular diseases accounts for about 50% of the total number of deaths. A large number of studies believe that the pathogenesis of common cardiovascular diseases such as atherosclerosis, hypertension, and stroke are closely related to the stress on blood vessels when blood flows, and the stress changes with the flow of blood in blood vessels. Therefore, providing an experimental device that simulates the flow of blood in blood vessels is of great significance for studying the etiology of cardiovascular diseases. In addition, in the field of tissue engineering blood vessel construction, ...
