[0040] Embodiment 1:

[0041] A contact negative oxygen ion therapeutic device includes a negative oxygen ion generator 1, an instrument housing 2, and an air intake unit 3 installed at the rear of the instrument housing 2. The negative oxygen ion generator 1 here is a prior art, which is mainly composed of a generating module and a carbon brush (or a discharge needle) connected to the generating module by a wire. When the negative oxygen ion generator 1 is powered on, the carbon brush will contact the oxygen in the air to form negative oxygen ions. In order to allow the negative oxygen ions to be blown out, the negative oxygen ion generator 1 is installed in front of the air intake unit 3 and the instrument housing 2 is constructed with an air outlet 4 for blowing out the negative oxygen ions; at the same time, in order to better correspond to wounds of different sizes, an instrument terminal 5 can be replaceably provided at the air outlet 4, and the instrument terminal 5 is used to cover the wound to cooperate with the instrument housing 2 to form an air duct 6 that isolates the outside; at the same time, a small fan 7 is also provided between the air intake unit 3 and the negative oxygen ion generator 1. When the small fan 7 is turned on, air can be blown toward the negative oxygen ion generator 1 and the generated negative oxygen ions can migrate to the wound through the air duct 6, so that the negative oxygen ions generated by the negative oxygen ion generator 1 can contact the wound and achieve a therapeutic effect.

[0042] The present invention designs an instrument housing 2 and installs a small fan 7 at the rear of the instrument housing 2. When the negative oxygen ion generator 1 is powered on, the airflow generated by the small fan 7 not only provides sufficient oxygen, but also allows the generated negative oxygen ions to reach the wound through an air duct 6 constructed by the instrument housing 2 and the instrument end 5. The channel isolates the external environment, so external factors that cause loss of negative oxygen ions are greatly reduced, thereby achieving the effect of improving the negative oxygen ion treatment of wounds.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the instrument housing 2 is constructed in a handle shape and is provided with an air inlet 31 at the end away from the air outlet 4. The air inlet 31 is covered with a detachable and fixed air inlet cover 32, wherein the air inlet cover 32 is used to filter dust, and the air inlet cover 32 is composed of a cover frame 321 covering the air inlet 31 and a plurality of filter cloths 323 fixed on the cover frame. The mesh number of the filter cloth 323 here is 55 to 65 meshes, which can filter dust. It should be noted that the filter mesh 323 can be installed on a frame-shaped object by fixing it with screws and pressure strips. This is a prior art and will not be elaborated on here. At the same time, the air inlet 31 and the air inlet cover 32 form an air inlet unit 3, and the instrument housing 2 includes a front section 21, a middle section 22, and a tail section 23. The use of a multi-section separated connection method can facilitate the installation and replacement of other components, wherein the air inlet 31 is located at the tail section 23 and the air outlet 4 is located at the front section 21, and the front section 21, the middle section 22, and the tail section 23 are detachably fixedly connected in sequence.

[0044] like Figure 1 , Figure 2 and Figure 5 , Figure 6 As shown, in this embodiment, the edge of the cover frame 321 is configured with an ear plate 322 and the ear plate 322 is fastened to the side wall of the tail section 23 of the instrument housing 2 by bolts, thereby realizing the detachable connection and fixation of the air intake cover 32, and at the same time, the small fan 7 is embedded in the tail section 23 and the air outlet 4 faces the front end (specifically as shown in FIG. Figure 5 As shown in , the outer shell edge of the small fan 7 is matched with the inner wall of the tail section 23. Water is applied to the outer shell edge of the small fan 7 and then inserted into it and wait for it to dry to achieve fixed installation. At the same time, fixing plates 24 are constructed on both sides of the middle section 22. Screw holes 25 are constructed on the fixing plates 24. The fixing plates 24 are fixed to the tail section 23 and the front section 21 by bolts passing through the screw holes 25. It should be noted that threaded holes for screwing in bolts are constructed on the front section 21 and the tail section 23 here.

[0045] like Figure 2 and Figures 6 to 11 As shown, the port portion of the front section 21 is narrowed first and then opened, and the air outlet 4 is located at the end of the opening. The design structure of narrowing first and then opening is adopted to accelerate the airflow here. At the same time, the instrument end 5 includes a trapezoidal cover body 51 of multiple specifications and sizes, please refer to Figure 2 , Figures 8 to 11 ,in Figure 2 The trapezoidal cover 51 on the top is of basic size, Figure 8 To increase the size, Fig. 9 Increase the size again and Fig.10 and Fig.11 For the corresponding Figure 8 and Fig. 9 Another angle view of the trapezoidal cover 51 is shown, and in order to achieve installation, the outer side wall of the trapezoidal cover 51 is symmetrically fixed with claws 52, and the side wall of the front section 21 located at the air outlet 4 is configured with a slot 53 corresponding to the claw 52, ​​so that the claw 52 is inserted into the slot 53 and the two are buckled. It should be noted that the two enlarged trapezoidal cover bodies 51 here are enlarged in size from the place other than the claw part, so the connection method is the same. Please refer to Fig.13 The specific buckling mode of the claw 52 and the slot 53 is that the mouth of the slot 53 has an inclined surface, and the end of the claw 52 also has an inclined surface. When inserted, the inclined surfaces contact each other, forcing the claw 52 to deform and insert into the slot 53. When it reaches the corner, the claw 52 is deformed and reset to achieve buckling. When unlocking is required, the claw 52 is pressed by a finger to deform so that the end of the claw 52 is not at the bottom of the buckled slot 53, and then pulled out to unlock. Please refer to Figure 2 In the front part, a sealing groove and a sealing gasket are provided between the trapezoidal cover body 51 and the port part of the front section 21, and this structure can prevent air leakage.

[0046] like Figure 2 and Figure 3As shown, in this embodiment, a T-shaped mounting groove 12 is symmetrically constructed on the side wall of the middle section 22, and a bracket 13 is embedded in the mounting groove 12. Here, the bracket 13 contacts the side wall of the mounting groove 12, and the negative oxygen ion generator 1 is installed on the bracket 13. Please refer to Figure 2 Here, the module of the negative oxygen ion generator 1 is installed on the bracket 13, and a fixing plate is bolted on the bracket 13, and the carbon brush is installed on the fixing plate by bolts to achieve stable installation. At the same time, the rear end of the bracket 13 presses the pressure cover 14 that seals the installation groove 12, and the bracket 13 is fixed by the downward pressure of the pressure block, and the pressure cover 14 is fixedly connected to the middle section 22 by bolts.

[0047] Embodiment 2:

[0048] like Figure 3 , Figure 4 On the basis of Example 1, this embodiment adds the following technical solutions: it also includes an ozone processor 8, which is used to process the derivative ozone generated by the negative oxygen ion generator 1 to prevent ozone from contacting the skin and oxidizing the skin, thereby damaging the wound. The ozone processor 8 includes a wind shield 81 (specifically, as shown in FIG. 1 ) which is arranged between the front section 21 and the middle section 22 and limits the position of the front section 21 and the middle section 22 after being fixed. Figure 3 , Figure 4 As shown), the wind hood 81 is used to collect the air blown out by the small fan 7 and guide it out at an outlet 82, and a processing cylinder 83 is connected to the outlet 82. An ultraviolet lamp 84 with a wavelength of 253.7 nanometers is installed inside the processing cylinder 83 along its length, wherein the ultraviolet lamp is controlled to emit ultraviolet light with a wavelength of 253.7 nanometers, which can be achieved by the existing technology, for example, by applying a coating on the outside of the ultraviolet lamp or by using a controller to control the voltage input voltage, and the ultraviolet light with a wavelength of 253.7 nanometers can effectively decompose ozone into oxygen.

[0049] like Figure 4 As shown, in this embodiment, in order to ensure sufficient decomposition of ozone, multiple groups of processing cylinders 83 are stacked and connected by fixed blocks 85, and multiple processing cylinders 83 are each provided with an ultraviolet lamp 84 with a wavelength of 253.7 nanometers. The multiple processing cylinders 83 are connected end to end through cylinders 86. Such a design can prolong the contact time between the derivative ozone and the ultraviolet light, so that the ozone can be fully decomposed as much as possible and the ozone concentration can be reduced to a safe value. At the same time, the end of the last processing cylinder 83 is connected and fixed with an air guide bend 87. The purpose of designing the air guide bend 87 is to prevent the ultraviolet light of the ultraviolet lamp 84 from being exposed to the outside world, and the bending design prevents the emission of light.

[0050] Embodiment 3:

[0051] like Figure 1 , Figure 8 and Fig. 9 As shown, a grid 9 with a cross-section is fixedly installed in the trapezoidal cover body 51, and wind belts 10 are fixedly connected at the intersection nodes of the grid 9. By designing the grid 9, the airflow can be separated, and when passing through the wind belt 10, the disturbance of the wind belt 10 can make the airflow simulate the effect of the breeze, avoiding direct blowing on the skin and causing the skin at the wound to dry out too quickly.

[0052] Embodiment 4:

[0053] like Fig.12 and Fig.13 As shown, the edge of the mouth of the trapezoidal cover body 51 is configured with an air outlet channel 11, and the air outlet channel 11 includes a first air hole 111 and a second air hole 112 configured in the transverse direction of the trapezoidal cover body 51, and a third air hole 113 and a fourth air hole 114 configured in the longitudinal direction of the trapezoidal cover body 51, the first air hole 111 is connected to the third air hole 113, the second air hole 112 is connected to the fourth air hole 114, and also includes a wind sweeping slot 11 configured at the edge of the mouth of the trapezoidal cover body 51 and connected to the third air hole 113 and the fourth air hole 114. 15. The wind-swept slot 115 is half-open and closed when in contact with the skin. When the airflow needs to be discharged, it first passes through the first air hole 111 and then moves along the length of the third air hole 113. Because the trapezoidal cover body 51 is in contact with the skin at this time, the airflow will gently caress the skin surface when passing through the wind-swept slot 115, and the breeze caressing the skin can promote the blood circulation of the skin around the wound and help the wound recover. Then the airflow passes through the fourth air hole 114 and is finally discharged to the outside through the second air hole 112.

[0054] The use steps of the present invention are:

[0055] Step 1: First, according to the size of the patient's wound, select a trapezoidal cover 51 of appropriate size. Specifically, press the claw 52 with your fingers to make the claw 52 deform and disengage, replace the trapezoidal cover 51 of inappropriate size, and then hold the appropriate trapezoidal cover 51 and forcefully insert it into the slot 53. It is considered to be stuck when a snap sound is heard;

[0056] Step 2: Cover the patient's wound with the trapezoidal cover 51. It should be noted that when the trapezoidal cover 51 is covered on the wound, its edge does not touch the wound, but contacts the surrounding intact skin. Then start the power supply (it should be noted that the power supply, power cord and other electrical components required to start the small fan 7, the negative oxygen ion generator 1 and the ultraviolet lamp 84 should also be included here, which will not be elaborated here). The small fan 7 starts to work and introduces the outside air. The negative oxygen ion generator 1 starts to prepare negative oxygen ions. The generated negative oxygen ions and their derivative ozone pass through the treatment cylinder 83. The ultraviolet light with a wavelength of 253.7 nanometers generated by the ultraviolet lamp 84 installed in the treatment cylinder 83 decomposes the ozone. At the same time, the ozone also oxidizes and kills the mixed bacteria in the airflow before it is decomposed.

[0057] Step three: The airflow containing negative oxygen ions is blown out through the wind guide bend 87, which prevents the penetration of ultraviolet light and accelerates the airflow when passing through a narrow place. Then, it reaches the grid 9 and is cut and disturbed by the wind belt 10, realizing the function of simulating a breeze. Then, it contacts the wound to promote the healing of the wound. Finally, it passes through the first wind hole 111 and moves along the length of the third wind hole 113. Because the trapezoidal cover body 51 is in contact with the skin at this time, the airflow will gently caress the skin surface when passing through the wind rafting groove 115. The breeze caressing the skin can promote the blood circulation of the skin around the wound and help the wound to recover. Then, it passes through the fourth wind hole 114 and is finally discharged to the outside through the second wind hole 112.

[0058] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
