Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an inflatable glove device for measuring wrist and hand swelling and a method of using the same. Background Art

[0002] Wrist and hand swelling caused by stroke or other diseases is relatively common, but there are currently few devices (methods) for measuring swelling, such as tape measure measurement, volume measurement (container filled with water), and dimensional measurement.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide an inflatable glove device for measuring wrist and hand swelling and a method of using the same, so as to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts a technical solution: an inflatable glove device for measuring wrist and hand swelling, comprising: a glove body, the glove body being provided with a non-deformable outer layer and an elastically deformable inner layer; wherein a plurality of pressure sensors are evenly disposed on a surface of the elastically deformable inner layer away from the non-deformable outer layer;

[0006] The non-deformable outer layer and the elastically deformable inner layer are nested to form the finger portion, thumb portion, palm portion and wrist portion of the glove body, and an inflation cavity is formed between the non-deformable outer layer and the elastically deformable inner layer, and the inflation cavity is connected to an external air source;

[0007] One side of the wrist is a closed end; the external air source, the plurality of pressure sensors and the controller are electrically connected.

[0008] In an optional embodiment, the finger portion is a whole, covering the index finger, middle finger, ring finger and little finger.

[0009] In an optional embodiment, the finger portion is split into an index finger portion, a middle finger portion, a ring finger portion and a little finger portion.

[0010] In an optional embodiment, the arrangement density of the pressure sensors on the fingers, thumb, palm and wrist is the same.

[0011] In another aspect, the present invention further provides a method for using the above-mentioned inflatable glove device for measuring wrist and hand swelling, comprising:

[0012] S1: Put the glove body on the swollen hand, and fit the closable end to the forearm;

[0013] S2: Inflate the air chamber, stop inflating the air chamber when all the pressure sensors reach a first threshold, and measure the air volume V1 of the air chamber;

[0014] S3: After an interval of time T1, the glove body is put on the swollen hand again, and the closable end fits the forearm;

[0015] S4: inflating the inflatable cavity again, stopping inflating the inflatable cavity when all the pressure sensors reach the first threshold, and measuring the inflated volume V2 of the inflatable cavity;

[0016] S5: Calculate the amount of swelling reduction V3 of the hand, V3 = V1 - V2.

[0017] In an optional embodiment, the first threshold value is F, and when the pressure values ​​f detected by a plurality of pressure sensors are all within a floating range of the first threshold value F, inflating the air into the inflation cavity is stopped.

[0018] In an optional embodiment, the swollen hand is partially swollen or completely swollen.

[0019] The beneficial effects of the present invention are:

[0020] (1) The glove device is put on the swollen hand before treatment, and the air is inflated into the inflation cavity. After multiple pressure sensors reach a threshold, the inflation volume V1 is measured. After a period of treatment, the glove device is put on the swollen hand again, and the air is inflated into the inflation cavity again. After multiple pressure sensors reach a threshold, the inflation volume V2 is measured. By calculating the difference between the two inflation volumes, the swelling reduction volume V3 of the swollen hand can be accurately calculated to test the treatment effect.

[0021] (2) The glove device extends to the wrist, which can not only test the amount of swelling reduced in the hand, but also in the wrist. In addition, since the density of the pressure sensors affects the test effect, as one of the main points of the present invention, the density of the pressure sensors in each part of the glove device is set to be the same, ensuring that the pressure sensors reach the threshold at the same time as much as possible. At the same time, the more pressure sensors are set, the more accurate the measurement results. The split arrangement of the fingers allows for more pressure sensors to be installed, resulting in higher measurement accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
