Because the volume of lymphedema is measured in the medical science at present, it is generally measured to adopt flexible rule measurement or drainage method, but because the measurement result error that flexible rule measurement method leads to because of measurement personnel's difference is very big, so can not adopt, drainage method measurement then needs the patient to put into the aquatic with the upper limbs, and the water of corresponding volume is discharged, the volume of rethread measurement water, reachs the volume of edema, this kind of measurement method can cause patient's upper limbs to be stained with water stain, influence measurement numerical value, and to the wounded patient of upper limbs, still can be infected by the bacterium in the aquatic. And therefore is not a good measurement method. Therefore, the present embodiment provides a lymphedema volume measuring device to solve the above problems.

Fig. 1 is a schematic structural diagram of a lymphedema volume measuring device provided in this embodiment, and fig. 2 is a front view of the lymphedema volume measuring device. As shown in connection with fig. 1-2, the device comprises a measuring body 1, an elastic membrane 2 and a measuring tube 3.

Specifically, as shown in fig. 1, the measurement body 1 has a rectangular parallelepiped structure, which can improve the stability during placement. The measuring body 1 has a measuring space 11 formed therein, and the volume of the measuring space 11 is a fixed value, but in this embodiment, the measuring space 11 is cylindrical, but may be formed in other shapes with a known volume. Inside the measuring space 11, a liquid is contained, which in this embodiment is water or kerosene. The end of the measuring body 1 is provided with an opening, which communicates with the measuring space 11, the measuring space 11 is configured to accommodate the upper limb of the patient, and the patient can put the upper limb deep into the measuring space 11 through the opening when using the measuring device.

The opening is hermetically provided with an elastic membrane 2, in this embodiment, the material of the elastic membrane 2 is rubber, and the thickness of the elastic membrane 2 is 2-5 mm, but other alternative and high-ductility materials, such as polypropylene material, may also be selected. Elastic membrane 2 sets up at the opening part, when the patient plans to stretch into measuring space 11 with the upper limbs in, can extrude elastic membrane 2 at first to ensure that patient's upper limbs can not be infected with the liquid in measuring space 11, avoided the risk of bacterial infection, in addition, elastic membrane 2 that proposes in this embodiment has still been done antibacterial treatment, guarantees promptly that every patient uses this device under aseptic environment.

Survey buret 3 and set up on measuring body 1, in order to guarantee the accuracy that numerical value read, survey buret 3 and be vertical setting, survey buret 3 and measure 11 intercommunications of space, be provided with the scale mark on surveying buret 3's the outer wall. That is, the liquid in the measurement space 11 flows into the measurement tube 3 under the pressure of the patient's upper limbs, and the data of this measurement is recorded by reading the value on the measurement tube 3.

Further, as shown in fig. 1, the measurement space 11 is opened at one end and opened at the other end with a communication hole 111, and the communication hole 111 communicates with the measurement pipe 3. A conduit 5 is arranged between the communication hole 111 and the measuring pipe 3, one end of the conduit 5 is hermetically connected with the communication hole 111, and the other end is hermetically connected with the measuring pipe 3. The guide pipe 5 is arranged in the measuring body 1, and one end of the guide pipe 5 is flush with the end part of the measuring body 1. In use, liquid in the measurement space 11 passes through the communication hole 111, the conduit 5, and then into the measurement pipe 3.

In order to facilitate reading of the values on the measuring tube 3 and to improve the stability during reading, a control valve 4 is arranged between the conduit 5 and the measuring tube 3, the control valve 4 being configured to control the switching between the measuring tube 3 and the conduit 5. In particular, the control valve 4 is arranged at the bottom of the measuring tube 3, the control valve 4 being configured to control the flow of liquid from the measuring space 11 into the measuring tube 3. When the liquid enters the measuring pipe 3 and the liquid is stable, the control valve 4 is closed to keep the liquid in the measuring pipe 3, and the value on the measuring pipe 3 is read; after the reading is finished, the control valve 4 is opened to return the liquid into the measurement space 11.

When using, patient's upper limbs move towards opening direction to extrude elastic membrane 2, elastic membrane 2 moves to measuring space 11, and with liquid extrusion in surveying buret 3, when patient's upper limbs were whole to enter into measuring space 11, and the steady back of liquid level on surveying buret 3, close control valve 4, read the numerical value on surveying buret 3. Since the edema volume is measured, the volume of the upper limb before edema and the volume of the upper limb after edema are collected and the difference between the two is made. Therefore, after two measurements, the measurement results of the previous and the next two measurements are recorded, and the difference value of the measurement data of the previous and the next two measurements is taken as the edema volume of the patient.

The device has the advantages of simple measurement principle, accurate measurement result and lower device cost, and avoids the problem of cross infection of patients with injured upper limbs in water.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
