Description

Fixing device with functional members

The present invention relates to a fixing device capable of simultaneously heating and cooling target parts of the body such as the thighs or lower legs on both sides and holding a functional member capable of applying an electric current or the like at an appropriate pressure. In particular, the present invention relates to a fixing device capable of intermittently holding a functional member at an actuated site without using the help or skill of a third party.

Currently, warming for improving blood flow in the affected area, cooling for sedating acute inflammation, pain relief and muscular atrophy improvement in the affected area, passive exercise and electrical stimulation for the purpose of recovering muscle strength are used. The treatment or care that was used is commonly performed. For example, Patent Documents 1 to 3 are known as techniques relating to a low frequency treatment device.

Usually, these treatments or care actions are performed by using a material having adhesiveness on the surface where the compress, warming agent, coolant, etc. adheres to the acting site, or by attaching the compress, warming agent, coolant, etc. to the acting site. Is placed on the affected area and then fixed with a bandage-like cloth, a wrapping material with a hook-and-loop fastener, a supporter, or the like. In addition, passive treatment or care for the purpose of analgesia, improvement of muscular atrophy, and recovery of muscular strength is performed by using passive treatment by another person or a low frequency treatment device.
However, when a sheet having adhesiveness is used intermittently, it is inevitably troublesome to replace the new sheet. For example, in low-frequency treatment devices, a gel material sheet (gel sheet) is often used as the contact surface of the electrode with the skin, but the gel sheet needs to be replaced due to the decrease in adhesiveness due to repeated use. The more users there are, the more often the replacement will occur.
As for the fixing method, a method of wrapping and fixing with a bandage, a wrapping material with a hook-and-loop fastener, a supporter, or the like is adopted, but the troublesome problem of the fixing method remains. In addition, depending on the site of action and the situation of the subject, there are cases where the help or skill of a third party is required for intermittent fixation. As a technique for fixing with a supporter, for example, Patent Document 4 is known.
Furthermore, for treatment or care by passive exercise or electrical stimulation, treatment by a qualified person may be required, and time and place restrictions are mentioned as a problem.

The present inventor examines the current situation and problems in treatment or care by heating, cooling, treatment or care by passive exercise in the target part such as the affected part in the medical field or at home, and solves the above-mentioned problem in the target part in the body. For example, a fixing device suitable for covering a part of the anterior to medial-lateral surface of the bilateral femur or the bilateral lower leg, or a part of the back surface to the medial-lateral surface was created.
The present inventor first puts one portable disposable body warmer (functional member) that does not use an adhesive material on the affected part on the front surface of the thigh on one side on the premise that both legs do not move in the sitting position. , I tried a method of wrapping a band-shaped cloth on it to cover it. By such a method, the functional member can be easily fixed without using an adhesive material and without relying on the technique of a third party, and further, treatment by passive exercise or electrical stimulation or treatment by electrical stimulation or It was confirmed that the time and place constraints associated with care could be improved.
However, when the above method is applied to the thighs and lower legs, there is only one site of action where one device can exert an effect at a time, and work efficiency when targeting the same site on both legs has been raised as an issue. .. The main target parts were narrowed down to the same surface (front or back) of the thighs or lower legs of both legs, and it was decided to use a weight to improve convenience by realizing that one device can work simultaneously with one device.
Furthermore, the present inventor has also found that the above-mentioned problems are common to other target parts such as the lower leg, forearm, upper arm, neck, head, and trunk other than the thigh.

Test Results The details of the test using the above-described first embodiment are described below.
In order to measure the pressure on the sensor at the target action site of the cylindrical surface of this fixing device, the contact pressure measuring device AMI3037-10 / AMI3037-10-SW (manufactured by AMI Techno Co., Ltd.) and the above 10 pressure sensors A measurement model for a fixing device was constructed with a cylinder with.

Quantitative verification method (measurement and calculation)
Control (without fixing device, without weight), Comparative Example 1 (with fixing device, without weight), Comparative Example 2 (with fixing device, 2 weights), Example 1 (fixed) depending on the presence or absence of the fixing device and the number of weights. The examination was divided into four conditions (with equipment and 3 weights). Under three conditions with the fixing device, each fixing device was placed on the cylindrical portion of the above-mentioned measurement model for the fixing device, and the pressure at each of the 10 points was measured at least 5 times. In the control, the measurement was performed at least 5 times in the same manner with nothing placed on the cylinder.
-Remove the outliers from each of the 5 measurement values at 40 points in total at 10 points for each of the 4 conditions for pressure measurement on the cylindrical surface of the fixing device, select 3 measurement values, and select the 3 measurement values at each location. The average value was calculated. After that, the difference obtained by subtracting the average value of the control "without fixing device" corresponding to each point from the average value of each part of "three conditions with fixing device" is calculated, and Comparative Example 1 and Comparative Example 2 , The three conditions of Example 1 were compared.
In order to avoid complication due to the large amount of data, the comparison of each condition is performed by the central sensor among the 10 pressure sensors on the left and right cylinders and the central sensor along the circumference of the cylinder including the central sensor in the circular cross-sectional direction. The data of a total of 3 sensors on one side and a total of 6 sensors on the left and right of the two sensors arranged at positions 4 cm from the inside and outside were adopted.
-Measurement of the contact area of the action site of the fixing device with the cylindrical surface At the same time as the measurement of "pressure on the two cylindrical surfaces of the fixing device", the action of the fixing device on the two cylindrical surfaces of the measurement model for the fixing device The contact area of the site was measured.

Table 1 above shows the pressure (kPa) values on the two cylindrical surfaces of the measurement model for the fixing device of the fixing device under the three conditions of Comparative Example 1, Comparative Example 2, and Example 1 acquired in this test. It is a table summarizing the results calculated by the above-mentioned method. Lt1-3 are numbers counting from the left outer side of the pressure sensors arranged on the upper surface of the left cylinder (left foot) when the measurement model for the fixing device is viewed from above. Lt1 is the left side (outside), Lt2 is the center, and Lt3 is the right side (inside). Similarly, Rt1-3 is a number counting the pressure sensors arranged on the upper surface of the right cylinder (right foot) from the left inner side. Rt1 indicates the left side (inside), Rt2 indicates the center, and Rt3 indicates the right side (outside).

As is clear from Table 1 above, it can be seen that the fixing device according to the first embodiment has a higher pressure as a whole as compared with the fixing device according to the comparative examples 1 and 2.
Further, in the fixing device according to the first embodiment, an increase in pressure is observed even in the central portion as compared with the fixing device according to the first and second comparative examples.
In the fixing device according to Comparative Example 2, it is recognized that the pressure increases on the outside of both the left and right cylinders and the difference from the fixing device according to Comparative Example 1 disappears in the central portion as compared with the reference value.

Table 2 above shows the results of "measurement of the contact area of the fixing device action site with the two cylindrical surfaces". The numerical values in the table indicate the contact area (cm ³ ) of the measurement model for the fixing device with the left and right cylinders under the three conditions of Comparative Example 1, Comparative Example 2, and Example 1.

As for the contact area of Comparative Example 2, since there is no weight in the central portion of the fixing device and there are weights only at both ends as compared with Comparative Example 1 and Example 1, a decrease in the contact area with respect to the cylinder in the central portion of the fixing device is observed. Was done. On the other hand, in Example 1, it was found that the problem of reduction in the contact area at the central portion of the fixing device was solved by adding one weight to the central portion of Comparative Example 2.
Summarizing the results of Test 1 above, a marked improvement in the pressure increase and pressure increase site area (skin contact equivalent site of this fixing device) of the measurement site in Example 1 was observed as compared with the comparative example. Was done.
Further, in the additional verification, by using a total of four weights in which the weight in the central portion of Example 1 was increased by one, the contact area of the working part of the fixing device with the working part of the cylinder was further increased, and the optimization was performed. It is known that it can be achieved.
Further, in the study using the measurement model in which the cylinder (outer diameter 14 cm) of the measurement model for the fixing device used in the study of Example 1 was replaced with a thin cylinder (outer diameter 11.4 cm) and the distance between the cylinders was adjusted. In the example using four weights, improvement in pressure and contact area on a part of the front surface and the side surface of the cylinder was recognized as in the above-mentioned additional verification.
From the above, when the fixing device is placed on the upper surface of a cylinder that imitates the human thigh, it is necessary to secure a sufficient contact area and fixation of the action site of the fixing device on the surface of a part of the front surface to the side surface of the cylinder. , It was found that this can be achieved by using a fixing device having the basic structure of Example 1.
