Basic of bionics theory, Establish a flow guidance on the skin surface to promote blood circulation, recover ossified/rigid muscles, guide the lymph to result in non-bacterial inflammation, in the meantime, the blood circulation system is used to the trash in human body and enhance self-repairing capability. It is bionics physiotherapy.
An origin - bionics of kintape technique and theory
- Surface froms of kintape
Kintape consists of three parts: the fabric, the glue, and the release paper. The glue surface shown below will appear after the release paper is peeled off.
How can a glue surface of this kind make such powerful changes to the human body? What if we replace it with other types of glue surfaces? A most fundamental design aesthetic, which is sometimes ignored by manufacturers, researchers, and operators, shall be considered to this end. Generally, this ability can be explained from the perspective of the waves of the glue surfaces, however it is insufficient in clarifying the reason functions can be introduced by waves or other forms.
Furthermore, many training institutions or manufacturers may certify the effect of a product through the senses of the human body or results in form changes after application; the form changes of subcutaneous fascia organizations before and after the application of kintape are usually taken as the contrastive case. Although this is correct, the reason why waves or other specific forms are adopted by glue surfaces cannot be clarified with those results, so the explanation is incomplete. It is similar to explaining the nutrients in food by the sense that someone is full; having a full stomach is not equal to the food containing needed nutrients.
Thus, we shall clarify the reason why glue surfaces in the form of waves and other kinds are adopted. Other shapes of glue surfaces can be designed, more effective products can be manufactured, and effective guidance can be introduced to our practical operation rules only if the theoretical problem is solved.
Before explaining this fundamental principle, I’d like to provide you a quick review to a most fundamental structure of the human body.
- Structure of veins in the human body
If we take the heart as the starting point of blood circulation, we shall use it as the terminal point, too. As the heart beats, the blood flows to the arms and legs through arteries, and returns to the heart through veins after the interchange of materials. This is how a complete circulatory system is formed. While the principle is easy to understand, it becomes more complex once an additional influence is added: the earth’s gravity.
When we stand on the ground, the heart is located at the position a little above the center of the human body. The strong pressure resulted from heartbeats is definitely able to push the blood into the top of our heads, while the blood can flow down even easier, as the earth’s gravity alone is sufficient to draw the blood back into our toes regardless of other factors. The problem, however, occurs in the later stage: when the blood returns to the heart through the veins, the pressure delivered by the heart is not sufficient to draw the blood from the toes back to the heart in opposition to the earth’s gravity. In addition, the heart beats through contracting and expanding. When the heart is contracting, the pressure is delivered outwards and the blood is pushed to the whole body. When the heart is expanding, however, will the blood in the arms and legs be drawn back to the heart like the ocean tides? If so, the blood will swarm in our blood vessels instead of remaining in its current state, and it will be impossible to achieve the interchange of materials.
If these assumptions are true and we still stand upright, the gravity will draw the blood in our veins back to the heart from positions above the heart (such as the head), which is relatively easy to be understood. However, the blood in the toes will always remain there, or wave up and down just like the tide. Since all of these do not occur in the human body, there must be a special structure to handle this issue.
This is how the human body handles this issue: the lengthwise cross section diagram of a vein in a human body is shown as follows:
We can tell from the diagram that there is a unidirectional structure with an orientating function on the inner wall of our veins, which is called the venous valve. It can force the blood to flow along one direction by closing itself if the blood tends to flow in another direction due to gravity or other factors. Therefore the blood can be prevented from flowing from right to left in the diagram shown above.
- Bionic principle of kintape
The essential function of kintape on the human body is to change its organizational structures through controlling the flow and direction of human interstitial fluid (blood). But how can kintape control interstitial fluid? Something special will be found if we consider kintape from another perspective:
Fig. A below will be seen if we observe the kintape after its release paper is removed:
But when we observe from a different perspective and view the kintape from the side, we can see the structure shown in Fig. B:
When we extend the cross section along its depth (width direction of the kintape), we will find that:
1. Similar figures of Fig. B will be acquired on any longitudinal cross section; we assume and name the figures in order as Fig. B1, Fig. B2, Fig. B3, as follows:
2. On each top longitudinal section, i.e. Fig. B1, Fig. B2, two connected glue points move in one direction orderly and continuously and finally connect with each other to form a glue figure as follows:
At this moment, please note that the glue bar is rectangular since no external force is changing it. Based on different production technologies and the standards of various manufacturers, the glue bar may be of other shapes. However, in spite of its form, the glue bar is vertical to fabrics, as shown in Fig. B.
Now we begin to change these glue points:
1. We stretch the kintape fully and apply it on the surface of the human body. If it is in a stationary state after applying, then Fig. C will be acquired:
2. Since kintape has elastic force, it is stretched when being applied onto the skin surface. When applying onto the surface of the human body, we assume that the kintape is applied from Point A to Point B (first affix Point A, stretch the kintape toward and bond at Point B). Since kintape has rebound resilience, when the kintape is applied onto the surface of the human body and there is no external force, Fig. D below will be acquired:
3. In Fig. D, the resilience force of fabrics drives the glue to deform towards one direction. Additionally, with the gluing, the skin is sufficiently firm, and the glue presses the skin, causing certain inferior fovea of the skin and driving the skin in one direction.
4. Under the skin, the skin’s form will change from Fig. D1 into Fig. E:
5. We can see two features in Fig. E:
a. There are infinite structures similar to Fig. E in the width direction of the kintape. And these structures are continuous; thus the opening indicated in Fig. E will connect and form a complete channel. The channel is where middle vacant bar of glue lies;
b. In each Fig. E, the deformed skin formed in the gluing point of the glue and skin is similar to a venous valve.
6. The subcutaneous fascia tissue of the human body is of no directivity, and the tissue fluid inside flows without order. However, as long as it flows, even if mildly, since it is beneath the skin applied with the kintape, the kintape has created:
a. A one-way flow guidance function similar to that of a venous valve;
b. A flowing channel of tissue fluid;
Therefore, the tissue fluid will flow in the direction set by the kintape to change the human body. This most basic principle—and way of realizing the principle—is the origin of all functions of kintape. It accounts for basic principle of effectiveness of kintape.
