Description

TECHNICAL FIELD

[0001] The utility model relates to medical joint detection instrument, concretely relates to a wrist joint angle measuring device. BACKGROUND

[0002] In medicine, joint angle measurement can be used to evaluate the joint health status of patients, for example, in the clinical detection of wrist joints, by measuring the bending angle of the wrist joint, whether the joint function of the patient is normal, whether there is arthritis, sprain, fracture or other injury, during the rehabilitation treatment process, regular measurement of the wrist joint angle can help the physical therapist monitor the recovery process of the patient, and adjust the rehabilitation program accordingly, regular inspection of the wrist joint angle can help identify potential work-related upper limb diseases and take preventive measures.

[0003] Unlike elbow joint and knee joint measurement, when measuring the wrist joint, the wrist joint needs to perform a palm lifting action to measure the patient's extreme angle, so direct angle measurement scale is prone to large errors, the existing wrist joint measurement method mainly measures the bending of the patient's palm by leaning on the plate with the assistance of medical staff, but the patient also needs to force his body close to the plate or squeeze the plate during this process, the whole process is relatively cumbersome for medical staff or patients, and it takes a long time, which may cause inaccurate measurement data. UTILITARY MODEL CONTENT

[0004] The wrist joint angle measuring device of the utility model can effectively solve the problem of the existing wrist joint measurement method that is not conducive to improving the measurement efficiency.

[0005] According to one aspect of the utility model, a wrist joint angle measuring device is provided, comprising:

[0006] A chassis;

[0007] A fixing frame connected with the chassis and arranged perpendicularly to each other;

[0008] A slide group comprising a first slide and a second slide, the first slide being movably arranged on the chassis, and the second slide being movably arranged on the fixing frame; the second slide is provided with a measuring scale;

[0009] Wherein, the elbow of the patient abuts against the first slide, and the second slide is provided with a fixing part to fix the palm of the patient, the second slide moves along the fixing frame under stress to drive the first slide to move, so that the wrist joint of the patient bends and the measuring scale outputs the measurement value.

[0010] In some embodiments, two sets of the sliding seat groups are provided, two first sliding seats move in opposite directions along the base frame, and two second sliding seats move in the same direction along the fixed frame, so that the bending angles of the wrists of the patient are measured at the same time. In this way, the patient can measure the bending angles of both wrists at the same time, improving the efficiency of measurement.

[0011] In some embodiments, the heights of the two second sliding seats are the same and they move at the same time after being forced, so that the patient can measure both wrists at the same time in the gesture of clasping hands. In this way, the patient can measure in the gesture of clasping hands, which is more in line with human mechanics, and the patient can be more relaxed during measurement.

[0012] In some embodiments, the base frame and the fixed frame are each provided with a sliding rail, and the first sliding seat and the second sliding seat are each provided with a sliding block, which is matched with the sliding rail to move the first sliding seat and the second sliding seat. In this way, the first sliding seat and the second sliding seat can be moved through the cooperation of the sliding rail and the sliding block.

[0013] In some embodiments, a sliding plate is provided on the fixed frame, and the sliding plate is connected with the two second sliding seats, so that the heights of the two second sliding seats are the same and they move at the same time. In this way, the two second sliding seats are moved at the same time through the sliding plate, which facilitates the patient to use and force in the gesture of clasping hands.

[0014] In some embodiments, a fixing part is provided on the sliding plate, which surrounds the patient's hand to fix the patient's palm on the second sliding seat. In this way, the fixing part is used to fix the patient's hand, so that the patient's palm remains relatively fixed on the second sliding seat, avoiding displacement when moving downward and affecting measurement.

[0015] In some embodiments, a soft pad is provided on the first sliding seat, and the patient's elbow abuts against the soft pad. In this way, the soft pad is used to improve the comfort of the patient during use.

[0016] In some embodiments, a first abutment groove is provided on the first sliding seat, and the patient's elbow abuts in the first abutment groove to limit the patient's elbow from disengaging the first sliding seat. In this way, the first abutment groove is used to prevent the patient's elbow from disengaging the first sliding seat during movement, while facilitating the patient's elbow to force the first sliding seat.

[0017] In some embodiments, a second abutment groove is provided on the second sliding seat, and the patient's palm abuts in the second abutment groove, and the patient's palm forces the inner wall of the second abutment groove to push the second sliding seat to move. In this way, the second abutment groove is used to facilitate the patient's palm to force the second sliding seat to move.

[0018] In some embodiments, a fixing member is also provided on the base frame. The fixing member is provided with a movable fixing rod, and the fixing rod is provided with a pressure plate. The fixing rod drives the pressure plate to move and forms a clamping effect with the base frame.

[0019] Compared with the prior art, the wrist joint angle measuring device of this invention has the following advantages:

[0020] This application utilizes a first slide and a second slide that move on a base and a fixed frame, respectively. The patient's elbow and palm rest on the first and second slides, respectively. The patient only needs to rely on the weight of their hand to move the palm downwards via the second slide, which simultaneously moves the first slide, causing the wrist joint to flex. Measurement is then taken using a measuring ruler. Since the entire process is completed by the movement of the first and second slides, the patient can relax more during the measurement process, making the process simpler and faster, reducing the workload of medical staff. The base and fixed frame also help improve the accuracy of the measurement. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] This utility model relates to a wrist joint angle measuring device, which is particularly suitable for measuring the bending angle of a patient's wrist joint. The wrist joint angle measuring device can be placed on a surface, which can be a horizontal surface, such as the countertop, tabletop, or other flat surface.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Figure 1 A wrist joint angle measuring device according to one embodiment of the present invention is schematically shown. The end pointing in the direction of gravity is designated as the lower side, as shown below. Figure 1 As shown, the wrist joint angle measuring device includes a base frame 1, a fixed frame 2, and a slide assembly 3.

[0033] like Figure 1 As shown, the base frame 1 is used to support other components and can be fixedly installed on the placement surface. The base frame 1 can be a plate structure or a long rod structure. The base frame 1 can extend horizontally. Preferably, the bottom surface of the base frame 1 is flat and parallel to the horizontal plane. Of course, through holes for fixing can also be opened on the base frame 1, and then fixed with screws or bolts for easy installation. If the weight of the base frame 1 allows, fixing may not be used. In some embodiments, casters are provided at the bottom of the base frame 1 to facilitate movement to other locations for easy carrying by medical personnel. In some embodiments, a handle 11 is provided on the base frame 1. The handle 11 can be used by patients or medical personnel for support, allowing patients to use one hand and for medical personnel to carry. The fixing frame 2 adopts a straight rod structure and is set on the base frame 1. The fixing frame 2 extends vertically, that is, the fixing frame 2 is set perpendicular to the base frame 1, and the fixing frame 2 and the base frame 1 are fixedly connected, such as by welding or riveting.

[0034] like Figure 1 , Figure 2 As shown, the slide assembly 3 is movably configured, comprising a first slide 31 and a second slide 32. The first slide 31 is movably mounted on the base frame 1, and the second slide 32 is movably mounted on the fixed frame 2. That is, the first slide 31 can move horizontally, and the second slide 32 can move vertically. The movement directions of the first slide 31 and the second slide 32 are perpendicular to each other. Preferably, the slide assembly 3 has two sets, allowing the patient to use both hands. Specifically, there are two first slides 31 and two slides 32. The two first slides 31 can be mounted opposite each other on the base frame 1, moving towards and away from each other. The two second slides 32 are movably mounted on the fixed frame 2 and have the same height. Both the fixed frame 2 and the base frame 1 are equipped with slide rails 4, and both the first slide 31 and the second slide 32 are equipped with sliders 5. The sliders 5 can slide and engage with the slide rails 4. Alternatively, existing guide rail structures can be used, allowing the first slide 31 and the second slide 32 to move on the base frame 1 and the fixed frame 2, respectively. In other embodiments, the slider 5 of the second slide 32 has a certain resistance to the slide rail 4 of the fixing frame 2, allowing it to move when the weight of the patient's hand is applied to the second slide 32, so that the patient can pre-adjust the position of the second slide 32 on the fixing frame 2 when not in use. A measuring ruler 7 is provided on the second slide 32, specifically an angle measuring ruler, preferably an electronic digital display joint range of motion measuring ruler, which can be referred to in the prior art and will not be described in detail here. Optionally, two or more measuring rulers 7 can be provided to allow for multiple measurements, and the final average value can be taken to improve the accuracy of the measurement. It should be noted that the part of the palm that contacts the first slide 31 can be a plane perpendicular to the horizontal plane or parallel to the side of the fixing frame 2.

[0035] Furthermore, such as Figure 2 As shown, the fixed frame 2 is provided with a sliding plate 21, which is connected to two second slide blocks 32 and can move simultaneously with the second slide blocks 32. The measuring ruler 7 can be set on the sliding plate 21. The sliding plate 21 helps to ensure that the two second slide blocks 32 are at the same height and move simultaneously.

[0036] Preferred, such as Figure 3As shown, a fixing part 22 is provided on the sliding plate 21 or the second slide block 32. The fixing part 22 surrounds the patient's hand, fixing the patient's palm to the second slide block 32. The fixing part 22 can be a strap structure, for example, using a single or double strap on the sliding plate 21, with Velcro on the strap. The Velcro is connected to form a wrapping strap shape. The fixing part 22 can cover part of the second abutment groove 321 (i.e., the two have partial projection overlap). In use, the patient's palm rests on the second abutment groove 321, and the medical staff or patient then uses the fixing part 22 to surround the patient's hand on the second slide block 32, fixing the patient's palm to the second slide block 32, so as to ensure that the patient's palm has a fixed gesture on the second slide block 32, thereby further improving the measurement efficiency. Of course, the fixing part 22 can also be directly provided on the second slide block 32. In other embodiments, the fixing part 22 can be other structures that can fix the palm, such as a groove, a plane with sensing information, a frame, a fixed sleeve, etc.

[0037] Furthermore, the first slide 31 is provided with a soft pad 312, which can be made of a soft and wear-resistant material, such as rubber or silicone. This makes it more comfortable for the patient's elbow to rest on the soft pad 312, avoiding hard contact injury to the elbow and improving comfort during use. Optionally, the first slide 31 is provided with a strap with Velcro, which can be tied to the patient's arm so that the patient's elbow can remain resting on the first slide 31.

[0038] In some embodiments, such as Figure 1 , Figure 2 As shown, a first abutment groove 311 is provided on the first slide 31. The first abutment groove 311 adopts an arc-shaped groove structure, preferably a groove structure with a side opening, so that the soft pad 312 forms an arc-shaped plate structure. The opening of the first abutment groove 311 faces the fixing frame 2, that is, the openings of the first abutment grooves 311 on the two first slides 31 are arranged opposite each other. During use, it is convenient for the patient to abut against the first abutment groove 311 through the opening. On the one hand, the first abutment groove 311 can prevent the patient's elbow from leaving the first slide 31 during the measurement process. On the other hand, the first abutment groove 311 makes it easier for the elbow to apply force to the second slide 32. Furthermore, as Figure 3 As shown, the second slide 32 is provided with a second abutment groove 321. Similarly, the second abutment groove 321 adopts a groove structure. The shape of the second abutment groove 321 is similar to the palm structure, that is, the shape of the second abutment groove 321 matches the shape of the human palm. The patient's palm can abut against the second abutment groove 321. The second abutment groove 321 can prevent the patient's palm from leaving the second slide 32 during movement. Moreover, the weight of the patient's palm can exert force on the inner wall of the second abutment groove 321 to push the second slide 32 to move, making the movement of the second slide 32 smoother.

[0039] When using, such as Figure 4 As shown, the positions of the first slide 31 and the second slide 32 are adjusted appropriately according to the patient's forearm size. The patient's palm and elbow rest on the second slide 32 and the first slide 31 respectively. The patient's palm can be fixed on the second slide 32 by the fixing part 22, or the fixing part 22 can be omitted and the patient's palm can actively rest on the second slide 32. When measuring both hands, the patient's palms are fixed by the fixing part 22 or actively rest on the second slide 32 to maintain the clasped hand gesture. The measuring ruler 7 is installed on the patient's hand. At this time, the patient is in a relaxed state. The weight of the hand or a slight downward force applied by the hand causes the second slide 32 to be under force. After being under force, the second slide 32 moves downward along the fixing frame 2. Since the elbow is continuously in contact with the first slide 31, it drives the first slide 31 to move in opposite directions. Therefore, the patient gradually moves downward with the clasped hand gesture. The patient's wrist gradually bends. Finally, the bending angle of the wrist is measured by the measuring ruler 7 and the final measurement value is output. The whole measurement process is relatively simple and improves the measurement efficiency.

[0040] Of course, such as Figure 5 As shown, the slide block 3 can also be set up as a set, allowing the patient to measure with one hand, that is, without the need to make a clasped hand gesture, and it is not limited to the use of the left or right hand, and can also achieve the effect of quick measurement. This method can also save the binding method of the fixing part 22. The patient can adjust the stability of the measurement himself and can choose according to the actual situation.

[0041] In some embodiments, such as Figure 6 As shown, the wrist joint angle measuring device also includes a fixing component 8, which is fixedly mounted on the bottom surface of the base frame 1. The fixing component 8 has an "L"-shaped shape and a movable fixing rod 9. The surface of the fixing rod 9 has a threaded structure, and the fixing component 8 has a threaded through hole. The fixing rod 9 moves up and down through the threaded engagement with the threaded through hole. One end of the fixing rod 9 has a pressure plate 91, which is located inside the fixing component 8. The other end of the fixing rod 9 has a handle-like structure for easy manual tightening. In use, the fixing component 8 is clamped onto the board or tabletop. By tightening the fixing rod 9, the pressure plate 91 is moved, thereby gradually pressing the pressure plate 91 against the board or tabletop. The pressure plate 91 and the base frame 1 form a clamping action, allowing the base frame 1 to be fixed in the desired position, facilitating disassembly, use, and relocation.

[0042] The above description is merely a preferred embodiment of the present utility model. To simplify the description, not all possible combinations of the various technical features in the above embodiments have been described, and this is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
