Description

Technical Field

[0001] The utility model relates to a testing device, in particular to an edema testing device. Background Art

[0002] When the skin is sunken to a depth of two millimeters and rebounds immediately, it is considered normal and there is no edema. Lower limb pitting edema is clinically divided into three degrees: mild, moderate, and severe according to the location of the edema and the degree of sunken edema. Figure 6 As shown): 1. If the edema depression is only limited to the ankle, when the depth of the skin depression is four millimeters, the rebound speed is within a few seconds, it can be determined as mild edema; 2. If the edema is not only in the ankle, but also local edema below the knee, when the depth of the skin depression is a six-millimeter pit, the rebound speed is within ten to twelve seconds, it can be determined as moderate edema; 3. If edema occurs in the entire lower limb, when the depth of the skin depression is an eight-millimeter pit, the rebound speed is more than twenty seconds, it can be determined as severe edema. In order to understand the degree of edema, it is necessary to perform a compression rebound test on the patient's suspected edema area. Currently, the test is mainly performed by manual compression, and then the rebound time is observed to determine the severity. However, this method cannot effectively control the compression depth. Doctors can only judge the compression depth based on experience, and then judge the degree of edema. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the utility model provides an edema testing device, which can accurately control the pressing depth and, combined with the rebound time, can help doctors accurately judge the degree of edema.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an edema testing device, comprising a pressing component, a handle, a screw, a plane, a scale, a reference component, a threaded sleeve and a base plate. The lower end of the handle of the pressing component is fixedly connected to the top end of the screw, a plane is eccentrically arranged along the central axis of the screw, a scale is provided on the plane, the screw is threadedly connected to the threaded sleeve, the lower end of the threaded sleeve is fixedly connected to the center of the base plate, and a through hole corresponding to the screw hole of the screw is provided at the center of the base plate.

[0005] In addition, the edema testing device proposed in the above embodiment of the utility model may also have the following additional technical features:

[0006] As a further improvement of the present invention, the lower end of the screw is a round head.

[0007] As a further improvement of the present invention, the pressing assembly, handle, screw rod, reference assembly, threaded sleeve and bottom plate are all made of plastic.

[0008] As a further improvement of the present invention, a sponge pad is provided at the bottom of the base plate.

[0009] As a further improvement of the present invention, an anti-slip groove is provided on the surface of the handle.

[0010] Through the above scheme, the utility model has at least the following advantages: compared with the conventional manual pressing and then judging by experience, the extension length of the screw is controlled by the scale, the threaded sleeve and the base plate, and then the screw is pressed and the base plate is limited, so the pressing depth can be accurately controlled. The quantified pressing depth combined with the rebound time can help doctors accurately judge the degree of edema. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, in the description of this specification, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0020] The edema testing device of the present invention is described below in conjunction with the accompanying drawings.

[0021] In the first embodiment of the present application, Figures 1 to 4 As shown, the edema testing device (hereinafter referred to as "this patent") includes a pressing component 1, a handle 1-1, a screw 1-2, a plane 1-3, a scale 1-4, a reference component 2, a threaded sleeve 2-1, a base plate 2-2 and a skin 3. The lower end of the handle 1-1 of the pressing component 1 is fixedly connected to the top of the screw 1-2, the screw 1-2 is eccentrically provided with a plane 1-3 along the central axis, the plane 1-3 is provided with a scale 1-4, the screw 1-2 is threadedly connected to the threaded sleeve 2-1, the lower end of the threaded sleeve 2-1 is fixedly connected to the center of the base plate 2-2, and a through hole corresponding to the screw hole of the screw 1-2 is provided at the center of the base plate 2-2.

[0022] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 2 As shown, in order to prevent the lower end of the screw rod 1-2 from being too sharp and hurting the patient, the lower end of the screw rod 1-2 is rounded.

[0023] In order to further optimize the working efficiency of the present application and reduce production costs, the pressing component 1, handle 1-1, screw 1-2, reference component 2, threaded sleeve 2-1 and bottom plate 2-2 are all made of plastic. To reduce the discomfort caused by the bottom plate 2-2 contacting the patient's skin, a sponge pad is provided at the bottom of the bottom plate 2-2. In order to make the operation more convenient, the surface of the handle 1-1 is provided with an anti-slip groove.

[0024] When in use, the edema testing device is installed and disinfected, and then put into use.

[0025] When the utility model is in use, the specific operations are as follows:

[0026] When using, Figure 5As shown, hold the handle 1-1 of the pressing component 1 and the threaded sleeve 2-1 of the reference component 2 with both hands respectively, and make the screw 1-2 rise and fall in the threaded sleeve 2-1 by twisting the handle 1-1, and judge how many millimeters the lower end of the screw 1-2 emerges from the bottom plate 2-2 by the scale 1-4, and then aim the bottom plate 2-2 at the skin 3 and press. When pressing, the bottom surface of the bottom plate 2-2 contacts the skin 3 and the pressing can be stopped. After waiting for two to three seconds, the patent can be removed, and then the timing can be started. When the depth of the depression of the skin 3 is two millimeters, the rebound speed is immediate rebound, which can be determined as a normal state without edema; when the depth of the depression of the skin 3 is four millimeters, the rebound speed is within a few seconds, which can be determined as mild edema; when the depth of the depression of the skin 3 is a six-millimeters deep pit, the rebound speed is within ten to twelve seconds, which can be determined as moderate edema; when the depth of the depression of the skin 3 is an eight-millimeters deep pit, the rebound speed is more than twenty seconds, which can be determined as severe edema.

[0027] In summary, the edema testing device of the embodiment of the utility model controls the extension length of the screw 1-2 through the scale 1-4, the threaded sleeve 2-1 and the base plate 2-2, and then the screw 1-2 is pressed and the base plate 2-2 is limited, so as to accurately control the pressing depth. The quantified pressing depth combined with the rebound time can help the doctor accurately judge the degree of edema and provide basic information for the doctor's subsequent treatment.
