Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a theoretical demonstration apparatus for teaching internal hemorrhoid varicose vein comprises a demonstration board 1, an organ picture 2 is arranged on one side of the demonstration board 1, an elastic water bag 3 is arranged on the demonstration board 1, the elastic water bag 3 is positioned on the organ picture 2, a water storage bag 6 and a water pump 8 are fixedly connected to one side of the demonstration board 1 far away from the elastic water bag 3, an output pipeline 7 is fixedly connected to one end of the water storage bag 6, an input end of the water pump 8 is connected to the outer side wall of the output pipeline 7 through a pipeline, an output end of the water pump 8 is fixedly connected to a first connecting pipeline 9, one end of the first connecting pipeline 9 far away from the water pump 8 penetrates through the demonstration board 1 and is connected to the elastic water bag 3, a second connecting pipeline 10 is fixedly connected to one end of the output pipeline 7 far away from the water storage bag 6, one end of the second connecting pipeline 10 penetrates through the demonstration board 1 and is connected to the elastic water bag 3, control apparatuses 11 are arranged on the first connecting pipeline 9, an exhaust device is arranged on the output pipeline 7. The organ picture 2 is a coronal section of the rectum anal canal with printed contents, and the structures of the rectum end, the dentate line, the anal canal, the anal sinus, the internal and external anal sphincters and the like are marked on the organ picture, so that the interestingness and the specialty of the device are improved conveniently. Water is arranged in the water storage bag 6, and the water pump 8 is used for pumping the water to flow in the pipeline and the elastic water bag 3, so that the demonstration of the internal hemorrhoid varicose vein theory is convenient to realize. The elastic water sac 3, the first connecting duct 9 and the second connecting duct 10 represent the hemorrhoidal vascular network and the artery and vein, respectively, entering and exiting the hemorrhoidal vessels. The purpose of the exhaust device is to exhaust the excess gas inside the device when water is added into the water storage bag 6.
Further, the first connecting pipe 9 and the output pipe 7 are both hard water pipes. When the first connecting pipeline 9 is clamped by a clamp, the influence on the flow speed of water input into the first connecting pipeline 9 is reduced.
Further, the second connecting pipe 10 is a flexible water pipe. When the second connecting pipe 10 is clamped using the clamp, the increase affects the flow rate of the water introduced into the second connecting pipe 10.
Further, the control device 11 is a clip, and the control device 11 and the elastic water bag 3 are both positioned on the same side of the demonstration board 1. The deformation of the elastic water bag 3 is facilitated by influencing the flow speed of water inside the first connecting pipeline 9 and the second connecting pipeline 10. Control device 11 and elasticity water pocket 3 all are located the same side of demonstration board 1, and the purpose is that the student is direct-viewing to observe that the teacher utilizes control device 11 operation to influence the inside velocity of water flow of first connecting pipe 9 and second connecting pipe 10 to be convenient for the quick understanding internal hemorrhoid varicose vein theoretical knowledge of student.
Further, the top of the demonstration board 1 is provided with a hanging rope 4. It is convenient to hang the demonstration board 1 on a wall.
Further, the bottom of one side of the demonstration board 1 close to the water storage bag 6 is provided with a detachable bracket 5. It is convenient to support the demonstration board 1.
Further, the demonstration board 1 is connected with a fixed block 12 through a fixing screw 14 near the bottom of one side of the water storage bag 6, a fixed cylinder 13 with a hollow setting and a bottom opening is fixedly connected to the fixed block 12, and the fixed cylinder 13 is sleeved on the outer side wall of the top of the support 5. The support 5 and the demonstration board 1 can be conveniently mounted and dismounted.
Further, the water storage bag 6 and the elastic water bag 3 are positioned on the same horizontal plane.
Further, the exhaust device comprises an exhaust pipe 15 fixedly connected to the top of the output pipeline 7 and disposed at the position corresponding to the output pipeline 7, and a control valve 16 is disposed on the exhaust pipe 15. The exhaust pipe 15 is used for exhausting excess gas inside the device when water is added into the water storage bag 6, and the control valve 16 is used for maintaining the sealing performance of the whole device.
The utility model discloses in, when whole hydrologic cycle steady flow, the business turn over rivers velocity of flow of top water pump 8 work business turn over water pipe under normal conditions is the same, and 3 volumes of elasticity water pocket remain unchanged, and rivers only circulate in the pipeline between elasticity water pocket 3 and water pump 8. When the same clamp (used for representing additional pressure) is respectively arranged on the first connecting pipeline 9 and the second connecting pipeline 10 on the elastic water bag 3, the first connecting pipeline 9 is a hard water pipe, and the reduction of the inflow flow rate is small due to small extrusion deformation amplitude; the second connecting pipe 10 is soft, the flow speed of the outlet water is reduced more, and the balance of the water flow in and out of the elastic water bag 3 is broken. Since the whole system is closed, the water pump 8 will suck more water from the water storage bag 6 to compensate the difference of the two flows, resulting in the volume of the elastic water bag 3 increasing. When the volume of the elastic water bag 3 is increased, the clamp is removed, and the system returns to the state of the same inflow and outflow rate, but the elastic water bag 3 cannot be shrunk. The process completely simulates the process of hemorrhoid vein compression leading to hemorrhoid vascular plexus expansion, the device has good creativity, specialty, interactivity and interestingness, can attract the attention of students in the teaching process, mobilizes the subjective motility, teaches in lively activities, and has a good teaching effect.
The utility model discloses the standard part that uses all can purchase from the market, and dysmorphism piece all can be customized according to the description with the record of drawing of description, and the concrete connection mode of each part all adopts conventional means such as ripe bolt, rivet, welding among the prior art, and machinery, part and equipment all adopt prior art, and conventional model, including circuit connection adopts conventional connection mode among the prior art, does not detailed here again.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
