Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a two-minute stepping test evaluation device. Background Art
[0002] The two-minute step test is a method of evaluating cardiopulmonary function by measuring the number of steps that the subject can reach within two minutes. The subject's knee reaches or exceeds the height of the midpoint of the line between the patella and the anterior superior iliac spine when stepping. The key to the technique is to accurately judge whether each step of the subject reaches the height of the midpoint of the line between the patella and the anterior superior iliac spine.
[0003] In the existing two-minute stepping test, the subject needs to stand in a test area between two walls and step for two minutes according to the height of the light pre-marked or set on the wall or other objects. The stepping height is the midpoint of the line connecting the upper edge of the patella and the anterior superior iliac spine. Medical staff records the number of times the patient reaches the standard stepping height within two minutes and evaluates cardiopulmonary function against the standard.
[0004] However, the existing two-minute stepping test is mostly used in the community, and is often completed by manual measurement and visual counting methods, which is highly subjective. At present, medical staff need to measure the position of the patient's anterior superior iliac spine against the wall and mark it on the wall, then measure the position of the patient's upper edge of the patella against the wall and mark it on the wall, and then use a ruler to measure the center position of the two marked points and mark it on the wall, and then the patient starts stepping training. This operation method has the problems of inconvenience in the marking process and recording deviation, which are: on the one hand, it is time-consuming for medical staff to measure the relevant distances with a ruler, which is prone to deviations; on the other hand, medical staff must be highly concentrated during the technical process, otherwise it is easy to cause counting errors and inaccurate experiments. Utility Model Content
[0005] The utility model provides a two-minute stepping test evaluation device, which is used to solve the technical problems of inconvenient marking process and recording deviation in the existing two-minute stepping test operation method.
[0006] The technical solution adopted by the utility model is as follows:
[0007] A two-minute stepping test evaluation device comprises a base with a support rod on the top, a measuring body slidably connected to the support rod, a sensing mechanism for detecting the number of times a patient's leg lifting height reaches a standard within two minutes is provided at the outer midpoint of the measuring body, a first marking rod and a second marking rod are slidably connected to the measuring body in the vertical direction in sequence, and a linkage mechanism for maintaining the vertical distance between the first marking rod and the sensing mechanism and the vertical distance between the second marking rod and the sensing mechanism the same is provided inside the measuring body.
[0008] According to the above scheme, first, let the patient stand on the base, then slide the measuring body along the support rod so that the end of the first marking rod is at the same horizontal line with the patient's anterior superior iliac spine, then the medical staff keeps the position of the first marking rod unchanged, and then stretches and adjusts the second marking rod up and down. At this time, under the action of the linkage mechanism, the vertical distance between the first marking rod and the sensing mechanism and the vertical distance between the second marking rod and the sensing mechanism remain the same. At the same time, the measuring body further slides on the support rod under the action of the linkage mechanism. When the end of the second marking rod is at the same horizontal plane with the upper edge of the patient's patella, the sensing mechanism on the measuring body is just in line with the midpoint of the line connecting the upper edge of the patient's patella and the anterior superior iliac spine. Then the medical staff fixes the position of the measuring body, and then fixes the linkage mechanism to lock the positions of the first marking rod and the second marking rod. Then the sensing mechanism is turned on to detect the number of times the patient's leg lifting height reaches the standard within two minutes. By using this device, there is no need to find a wall position to conduct the test, and there is no need for medical personnel to measure the relevant distances with a ruler. The midpoint of the line connecting the upper edge of the patient's patella and the anterior superior iliac spine can be found by simply moving the position of the measuring body and the positions of the two marking rods, and the marking process is very convenient.
[0009] Preferably, the sensing mechanism includes a cross bar fixed to the outside of the measuring body, and straight bars are respectively provided at both ends of the cross bar, wherein a light signal transmitter is provided on one side of one of the straight bars, and a light signal receiver matching the light signal transmitter is provided on one side of the other straight bar; a counter electrically connected to the light signal receiver is provided inside the measuring body, and a display screen and a speaker electrically connected to the counter are provided on the outer side of the measuring body.
[0010] Using the above scheme, when performing a two-minute stepping test, the signal emitted by the optical signal transmitter is received by the optical signal receiver, and the counter counts to 0 at this time. Then the patient starts stepping, and when the leg is raised to the midpoint of the line connecting the upper edge of the patella and the anterior superior iliac spine, the signal emitted by the optical signal transmitter will be blocked. Then when the patient's leg falls again, the signal emitted by the optical signal transmitter is received by the optical signal receiver again, and the counter counts to 1 at this time. And so on. After two minutes, the number recorded by the counter is the number of times the patient has reached the standard stepping limit.
[0011] Preferably, the linkage mechanism includes a meshing gear arranged inside the measuring body and rotatably connected to the measuring body, and the meshing gear is arranged between the first marking rod and the second marking rod; the side walls of the first marking rod and the second marking rod are respectively provided with first racks meshing with the meshing gear; the central axis of the meshing gear is in the same horizontal plane as the cross bar.
[0012] By adopting the above scheme, after fixing the height position of the first marking rod, the position of the second marking rod is then adjusted by stretching it up and down. At this time, the first rack on the second marking rod drives the meshing gear to rotate. Since the first rack on the first marking rod is meshed and connected with the meshing gear, and the first marking rod and the support rod remain fixed, the meshing gear drives the measuring body to slide along the support rod during the rotation process, thereby adjusting the position of the sensing mechanism while adjusting the second marking rod, and the vertical distance between the first marking rod and the sensing mechanism and the vertical distance between the second marking rod and the sensing mechanism remain the same.
[0013] Preferably, a first locking mechanism is provided between the measuring body and the support rod, and the first locking mechanism includes a constraint ring sleeved on the outside of the support rod, the constraint ring is slidably connected to the support rod and fixedly connected to the outer side of the measuring body; a connecting bolt is penetrated through the opening part of the constraint ring, one end of the connecting bolt is hinged with a cam handle, and the other end is threadedly connected with an adjusting knob, and the cam of the cam handle abuts against the outer side of the constraint ring opening.
[0014] By adopting the above scheme, when the measuring body needs to be fixed, the cam handle is pulled so that the cam of the cam handle abuts against the outer side of the opening of the constraint ring, and the constraint ring is tightened to squeeze the support rod, thereby fixing the measuring body and the support rod. In addition, the tightening degree of the constraint ring can be adjusted by adjusting the knob.
[0015] Preferably, the measuring body is provided with a second locking mechanism for locking the first marking rod and the second marking rod, the second locking includes a second rack arranged on the side of the first marking rod, and the interior of the measuring body is slidably connected with a locking member, one end of the locking member is provided with a locking groove matching the second rack, and the other end is arranged through the outside of the measuring body.
[0016] By adopting the above scheme, after adjusting the position of the second marking rod so that its top end is aligned with the upper edge of the patient's patella, the locking piece located outside the measuring body is pressed so that the locking groove at the inner end of the locking piece is locked with the meshing teeth on the second rack, thereby locking the positions of the first marking rod and the second marking rod.
[0017] Preferably, the measuring body is also provided with an adjustment mechanism for adjusting the distance between the first marking rod and the second marking rod, the adjustment mechanism includes a third rack arranged on the side of the second marking rod, and the interior of the measuring body is provided with a transmission gear meshing with the third rack, and the transmission gear is meshed with an operating gear rotatably connected to the measuring body, and the meshing teeth of the operating gear are arranged on the outside of the measuring body.
[0018] By adopting the above solution, medical personnel rotate the operating gear to drive the transmission gear to rotate and then drive the meshing gear to rotate, and drive the second marking rod to slide through the third rack.
[0019] Preferably, the ends of the first marking rod and the second marking rod are respectively fixedly connected with pointing plates.
[0020] By adopting the above solution, the pointing plate facilitates the ends of the first marking rod and the second marking rod to be aligned with corresponding parts of the patient.
[0021] Preferably, the first marking rod is fixedly connected to an auxiliary fixing plate on a side away from the pointing plate, the auxiliary fixing plate is slidably sleeved on the outside of the support rod, and the auxiliary fixing plate is penetrated by a fixing column on the side away from the first marking rod; the fixing column is threadedly connected to the auxiliary fixing plate, and the inner end of the fixing column is provided with an anti-slip sleeve that matches the outer side surface of the support rod.
[0022] By adopting the above solution, when fixing the first marking rod, the fixing column is rotated so that the anti-slip sleeve at the inner end of the fixing column is pressed against the support rod, thereby completing the fixing of the first marking rod.
[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0024] 1. By using this device, there is no need to find a wall position to conduct the test, and there is no need for medical personnel to measure the relevant distance with a ruler. The midpoint of the line connecting the upper edge of the patient's patella and the anterior superior iliac spine can be found by moving the position of the measuring body and the positions of the two marking rods. The marking process is very convenient and is not prone to errors.
[0025] 2. After fixing the height position of the first marking rod, stretch the second marking rod up and down to adjust the position. At this time, the first rack on the second marking rod drives the meshing gear to rotate. Since the first rack on the first marking rod is meshed with the meshing gear, and the first marking rod and the support rod remain fixed, the meshing gear drives the measuring body to slide along the support rod during the rotation process, thereby adjusting the position of the sensing mechanism while adjusting the second marking rod, and the vertical distance between the first marking rod and the sensing mechanism and the vertical distance between the second marking rod and the sensing mechanism remain the same.
