Abstract
Description
Technical Field
[0001] This utility model relates to the field of teaching equipment technology, and in particular to a pulse simulation device. Background Technology
[0002] A pulse simulator is a device used to simulate and analyze human pulse patterns, widely applied in Traditional Chinese Medicine (TCM) diagnosis, teaching, and research. In the pulse diagnosis training component of the "TCM Diagnostics" course, students' perception of common pulse characteristics is crucial. Therefore, effective simulation of common pulse patterns is essential for students learning the pulse diagnosis component of TCM diagnosis. Existing pulse simulators generally use a single device to simulate multiple pulse patterns; for example, a simulated arm is used to simulate a deep or superficial pulse. However, the thickness of the arm and the blood vessels inside are fixed, which is inconsistent with the fact that the thickness of a patient's pulse does not change rapidly in the same person. Even opposite pulse patterns, such as slippery and hesitant pulses, long and short pulses, large and thin pulses, and wiry and soft pulses, are displayed on the same simulated arm. While the hardware parameters remain unchanged, the accuracy is severely limited. Utility Model Content

It also includes an oil delivery unit located inside the housing, a simulation unit detachably connected to the arm base and fitted inside the arm model, and a simulated blood vessel attached to the outside of the simulation unit and connected at both ends to the oil delivery unit's oil outlet and oil inlet, respectively.
[0006] Furthermore, the controller is electrically connected to both the oil delivery unit and the analog unit.

[0027] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0028] Reference Figure 1-5 As shown, a pulse simulator includes a housing 1, an arm base 2, an arm model 3, and a controller 4. It also includes an oil delivery unit 5 located inside the housing 1, a simulation unit 6 detachably connected to the arm base 2 and fitted inside the arm model 3, and a simulated blood vessel 7 attached to the outside of the simulation unit 6 and connected at both ends to the oil delivery unit 5 at the oil outlet and oil inlet respectively.
[0029] It should be noted that in this application, the arm base 2 is located on the upper end of the housing 1, the arm model 3 is sleeved on one side of the arm base 2, and the controller 4 is located on the upper end of the housing 1. The housing 1 provides a platform and space for the placement of other components. The arm base 2 facilitates the installation of the arm model 3. The arm model 3 is usually made of silicone material to easily simulate real human skin. The controller 4 can control the components of the pulse simulator, which is prior art. For example, the delay control and DC-AC converter used in the controller of this application are prior art, and those skilled in the art can choose according to specific circumstances, which will not be elaborated further. The oil delivery unit 5 can deliver liquid paraffin to the simulated blood vessel 7 to simulate the state of blood. The simulation unit 6 can easily simulate the pulsation of human blood vessels and is controlled by the controller 4 to facilitate the simulation of pulse. The simulated blood vessel 7 can well simulate human blood vessels, making the tester feel more realistic when taking a pulse. In this application, the controller 4 is electrically connected to the oil delivery unit 5 and the simulation unit 6 respectively to ensure the continuous and stable operation of each component.
[0030] Specifically, the oil delivery unit 5 includes an oil storage tank 51, an oil pump 52, solenoid valve I 53, and solenoid valve II 54. The oil outlet of the oil storage tank 51 is connected to the oil inlet of the oil pump 52 via an oil pipe. The oil outlet of the oil pump 52 is connected to one end of the simulated blood vessel 7 via an oil pipe. The other end of the simulated blood vessel 7 is connected to the oil inlet of the oil storage tank 51 via an oil pipe. Solenoid valve I 53 is installed on the oil pipe between the outlet of the oil pump 52 and one end of the simulated blood vessel 7. Solenoid valve II 54 is installed on the oil pipe between the other end of the simulated blood vessel 7 and the oil inlet of the oil storage tank 51. The oil storage tank 51 is used to store liquid paraffin. The oil pump 52 can pump the liquid paraffin into the simulated blood vessel 7 through the oil pipe to simulate the state of blood. Solenoid valves I 53 and II 54 are closed after the oil is delivered into the simulated blood vessel 7. The liquid paraffin in the simulated blood vessel 7 can be adjusted according to the specific simulated pulse to ensure the accuracy of the simulation.
[0031] Specifically, the oil pipe between solenoid valve I 53 and one end of the simulated blood vessel 7, and the oil pipe between solenoid valve II 54 and the oil inlet of the oil storage tank 51 are connected by a connecting pipe 56. A solenoid valve III 55 is installed on the connecting pipe 56. A pressure sensor I 57 is installed on the oil pipe between solenoid valve I 53 and one end of the simulated blood vessel 7. Solenoid valve II 54 opens when the pressure of the simulated blood vessel 7 needs to be reduced when touched by a tester, simulating a decrease in blood vessel pressure. Solenoid valve III 55 is initially closed. Solenoid valves I 53, II 54, and III 55 can be commercially available products of model VX2120-X64, or those skilled in the art can choose according to their needs. Pressure sensor I 57 can be a commercially available RS485, and oil pump 52 can be a commercially available CBT1, or those skilled in the art can choose according to their needs.
[0032] Specifically, the simulation unit 6 includes a support 61, a placement box 63, and push-pull electromagnets 64; the support 61 has a through groove 62; the placement box 63 is located below the through groove 62 and is detachably connected to the support 61; three push-pull electromagnets 64 are detachably connected side by side inside the placement box 63, with their upper ends extending into the through groove 62 and in contact with the simulated blood vessel 7; the lower end of the placement box 63 has a through hole 65 for facilitating the extension of the lower end of the push-pull electromagnets 64; a pressure sensor II 66 is fixedly connected at the contact point between the upper end of the push-pull electromagnet 64 and the simulated blood vessel 7. The bracket 61 is used to support the other components of the simulation unit 6, facilitating the arrangement of the other components; the placement box 63 is used to place the push-pull electromagnet 64; the push-pull electromagnet 64 can move according to the pulse characteristics when the simulated blood vessel 7 is filled with liquid paraffin. The push-pull electromagnet 64 is a commercially available product, and the stroke can be selected according to the pulsation of the simulated pulse to ensure accuracy; the push-pull electromagnet 64 can be the commercially available product AH-104B, and the pressure sensor II can be the commercially available product F5Y-A. Those skilled in the art can also choose as needed.
[0033] Specifically, in order to make the contact between the push-pull electromagnet 64 and the simulated blood vessel 7 more stable, the upper end of the push-pull electromagnet 64 is bonded to the contact point with the simulated blood vessel 7.
[0034] Specifically, in order to prevent the push-pull electromagnet 64 from wobbling left and right during operation and causing a decrease in the accuracy of pulse simulation, a limiting plate 68 for fixing the push-pull electromagnet 64 is horizontally fixed inside the placement box 63; the limiting plate 68 is located in the middle of the three push-pull electromagnets 64.
[0035] Specifically, a buffer pad 67 is provided between the placement box 63 and the connection position of the push-pull electromagnet 64. The buffer pad 67 can reduce the noise when the push-pull electromagnet 64 is working, making it easier for the tester to diagnose the pulse.
[0036] In this application, based on the characteristics of the actual simulated pulse, the simulated blood vessel 7 is made of sodium alginate, polytetrafluoroethylene, or polyurethane. The diameter of the simulated blood vessel 7 is 0.5mm~0.8mm, and the wall thickness is 0.05mm~0.1mm. This application allows for a reasonable selection based on the specific pulse pattern.
[0037] The working principle of this utility model:
[0038] This invention simulates a pulse pattern through the coordinated operation of various components. Compared to existing multi-functional pulse pattern simulators, it more closely resembles the real human condition. The fixed parameter settings for a single pulse pattern better reflect the fact that the pulse thickness of a patient does not change rapidly within the same individual, resulting in a more accurate simulation. First, the material, diameter, and wall thickness of the simulated blood vessel 7 are determined based on the characteristics of the single pulse pattern to be created. A suitable simulated blood vessel 7 is selected, and liquid paraffin from the oil storage tank 51 is delivered into the simulated blood vessel 7 via the oil pump 52. The pressure inside the simulated blood vessel 7 is detected by the pressure sensor I 57. Once the pulse pattern value is reached, the pressure sensor II 66 sends a signal to the controller 4, which then controls the solenoid valve. I53 and solenoid valve II54 are closed. Then, according to the characteristics of the pulse, a push-pull electromagnet 64 of appropriate specifications is selected to squeeze and release the simulated blood vessel 7 to simulate the pulse. At the same time, the pressure sensor II66 detects the pressure of the finger when diagnosing the pulse, so as to facilitate the adjustment of the pressure inside the simulated blood vessel 7 and make the simulation state more realistic. By reasonably selecting the specifications of the simulated blood vessel 7, the push-pull electromagnet 64, and the pressure inside the simulated blood vessel 7, the pulse simulator can produce a single pulse. This application can produce a set of 12 common pathological pulses and normal pulses corresponding to the undergraduate textbook "Traditional Chinese Medicine Diagnostics" through the standardization and fixation of hardware materials and parameters, so as to facilitate pulse simulation diagnosis with higher realism.
[0039] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
