Technical Field

[0001] The invention relates to the technical field of acupoint physiotherapy plasters, and in particular to a physiotherapy plaster for improving blood circulation and relieving pain and a preparation method thereof. Background Art

[0002] Paste therapy, also known as external application therapy, is a method of grinding the medicine into fine powder, mixing it with various liquids into a paste, and applying it to the required acupuncture points or affected areas to treat diseases. It is one of the external treatments commonly used in traditional Chinese medicine. In addition to allowing the drug to directly reach the lesion to exert its effect, the paste therapy can also allow the drug properties to pass through the skin and pores from the outside to the inside, and through the meridians to the internal organs, so as to regulate the qi, blood, yin and yang of the internal organs, strengthen the body and eliminate evil, and thus cure the disease.

[0003] Chinese Patent Publication No.: CN113521552A The present invention discloses a medical device patch, which relates to a medical device for Chinese medicine physical therapy. In the past, patch products were prone to uneven mixing and poor effects due to the mixing of far-infrared ceramic powder in hot melt adhesive. The present invention provides a patch product with more stable far-infrared wave emissivity and more uniform and powerful far-infrared wave. The present invention structurally consists of non-woven fabric, hot melt adhesive, far-infrared ceramic powder (normal emission frequencies are 0.95, 0.90, and 0.85, respectively), magnetic powder, and release paper. On the basis of the original hot melt adhesive, far-infrared ceramic powder, and release paper structural composition mixed ratio, two or more far-infrared ceramic powders and hot melt adhesive are selected to combine layers, and glue is applied in layers to strengthen and expand the intensity and stability of the far-infrared waves of the patch product. The present invention provides a new type of physical therapy patch medical device structural composition and production process. As a physical therapy medical device, it does not contain drugs, has high safety performance, and can be carried with you. When used, it can be attached to the affected area or applied according to acupoints. This shows that the medical device applicator has problems such as excessive friction due to wear between the tabletting tube and the guide cylinder, which results in reduced structural stability of the cutting assembly, and short heating time, which leads to uneven mixing of the raw materials of the base layer skeleton and reduced preparation stability.

[0051] Step S8, obtaining the actual temperature of the guide cylinder of the cutting assembly after the tablet pressing tube runs a single cycle in the corresponding working mode;

[0052] Step S9, determining the rotation speed of the tablet pressing tube based on the actual temperature of the guide cylinder.

[0053] Specifically, the cutting components for preparing a compress for improving blood circulation and relieving pain include:

[0054] Press plate 5;

[0055] A first cylinder 3, which is connected to the pressing plate 5 via a first telescopic connecting rod 2, and is used to provide power for the vertical reciprocating motion of the pressing plate;

[0056] a first telescopic connecting rod 2 connected to the pressing plate 5 for transmitting the pressure of the first cylinder 3 to the pressing plate 5;

[0057] A second cylinder 11, which is connected to the pressing plate 5 via a second telescopic connecting rod 12, and is used to provide power for the vertical reciprocating motion of the pressing plate;

[0058] a second retractable connecting rod 12 connected to the pressing plate 5 for transmitting the pressure of the second cylinder 11 to the pressing plate 5;

[0059] A tabletting tube 6 connected to the pressing plate 5 for tabletting and cutting the base layer;

[0060] A guide cylinder 9, which is connected to the tablet pressing tube 6 and is used to limit the pressure direction of the tablet pressing tube;

[0061] The bottom plate 8 is connected to the guide cylinder 9 and is used to fix the finished substrate layer to be pressed and cut.

[0062] Specifically, the horizontal rotation of the tablet pressing tube is achieved by a horizontal rotation structure of the tablet pressing tube, wherein the horizontal rotation structure of the tablet pressing tube comprises:

[0063] A connecting rod 4, which is connected to the tablet pressing tube 6 and is used to transmit the rotational power to the tablet pressing tube 6;

[0064] The stepper motor 1 is connected to the connecting rod 4 to provide rotational power.

[0065] Specifically, the actual pressure on the side wall of the guide cylinder 9 is measured by a pressure sensor 7 disposed on the side wall of the guide cylinder 9 .

[0066] Specifically, the bottom plate 8 is provided with a sheet pressing hole which is connected with and matched with the guide cylinder.

[0067] Specifically, the bottom end of the tablet pressing tube can penetrate into the tablet pressing hole of the bottom plate 8 to cut the patch.

[0068] Specifically, the working principle of the cutting assembly for preparing a plaster for improving blood circulation and relieving pain is as follows: the material of the plaster is placed under the base plate, the first cylinder drives the first retractable connecting rod and the second cylinder drives the second retractable connecting rod to descend simultaneously to drive the pressing plate to descend, the pressing plate drives the tablet pressing tube to slide downward in the guide cylinder, the cutting edge at the lower end of the tablet pressing tube presses the large plaster into a small plaster, and then the first retractable connecting rod of the first cylinder and the second retractable connecting rod of the second cylinder are retracted simultaneously, and the pressing plate and the tablet pressing tube rise.

[0069] Specifically, the actual temperature of the guide cylinder 9 is obtained according to the temperature sensor 10 disposed on the other side of the pressure sensor 7 on the side wall of the guide cylinder 9 .

[0070] Specifically, the stirring depth of the stirrer is the depth to which the stirring rod enters the mixed raw materials.

[0071] Specifically, the principle of the X-ray sensor detecting the number of pores in the prefabricated base layer is that X-rays can penetrate materials of different thicknesses. The X-ray sensor receives the X-rays that have passed through the object and converts them into electrical signals, which are further converted into digital images. When the X-rays pass through the pores in the prefabricated base layer, the brightness of the pores in the digital image is higher than that of the place without pores because the pores absorb less X-rays. The location where the pores appear is called the bright area, and the number of pores in the patch is obtained by counting the bright areas.

[0072] Specifically, the temperature sensor 10 is an infrared temperature sensor, and its detection principle is that all objects with a temperature above absolute zero will emit infrared radiation. The infrared temperature sensor receives the infrared radiation emitted by the object, measures its wavelength and intensity, and thus calculates the surface temperature of the object.
