Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a traditional Chinese medicine micro-needle positioning negative pressure blood stasis removal device and method for treating choroid stasis and blockage. Background Art

[0002] The traditional Chinese medicine micro-needle positioning negative pressure blood stasis removal device combines traditional Chinese medicine pricking bloodletting, cupping with modern vacuum technology and disposable micro-needle material science, achieving a device for removing blood stasis with fixed-point, minimally invasive and controllable negative pressure. It can quickly dredge the meridians and promote blood circulation to remove blood stasis under safe and quantifiable conditions, providing a minimally invasive and easily popularizable solution for various pain caused by blood stasis blockage and vascular stasis diseases;

[0003] For example, the thrombus meridian stasis micro-needle positioning removal instrument of "CN202843701U" includes an outer shell body. Inside the outer shell body, there is a power supply module that provides power for the entire instrument. There is also a suction and pressure pump inside the outer shell body. The suction and pressure pump obtains power from the power supply module. On the front side of the outer shell body, there is a pressure gauge and a pressure regulating unit. The pressure gauge is connected to the suction and pressure pump and displays the current vacuum pressure of the suction and pressure pump. The pressure regulating unit is provided with a manual pressure regulating knob. The pressure regulating unit controls the operation of the suction and pressure pump according to the difference between the expected vacuum pressure set by the manual pressure regulating knob and the current vacuum pressure detected by the pressure gauge. The suction and pressure pump is connected to an external vacuum tank with a micro-needle through a pressure output pipeline. The thrombus meridian stasis micro-needle positioning removal instrument described in the present utility model has a simple structure. It pierces the subcutaneous tissue through the micro-needle, sucks out thrombus toxins by controlling the degree of vacuum, can adjust the treatment intensity according to the condition of the user, is easy to operate, and is safe and reliable;

[0004] However, in the prior art, traditional Chinese medicine pricking bloodletting and cupping therapies have been practiced for a long time in dredging the meridians and promoting blood circulation to remove blood stasis. However, they still mainly rely on manual operation by doctors. Among them, the negative pressure of the tank body is uncontrollable and changes suddenly, often causing subcutaneous bruising. When the sealing is poor, it is necessary to repeatedly ignite or pump air to reattach. Moreover, the needles and cupping devices are often reused, and it is easy to leave blood stains and clots in the cleaning dead corners, bringing the risk of cross-infection. Although there is a device with a single-chamber cup structure combining a micro-needle array and negative pressure suction in the prior art, once the negative pressure is started, it directly acts on the skin, and there is still instantaneous pulling pain. Summary of the Invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the defects in the prior art that there are instantaneous pulling pain and bruising due to negative pressure, and it is difficult to fully sterilize and clean the instruments.

[0007] To solve the above technical problems, the present invention provides the following technical solutions:

[0008] On the one hand, the present invention provides a traditional Chinese medicine micro-needle positioning negative pressure silt cleaning device for treating choroid stasis and blockage, which comprises a fixed seat and a negative pressure cup. The negative pressure cup is detachably arranged on the fixed seat. Two vacuum pumps for communicating with the negative pressure cup are arranged on the fixed seat. The negative pressure cup comprises an outer cup, an inner cup and a needle holder. The outer cup is sleeved outside the inner cup and is arranged with the opening facing downwards. A first chamber is formed between the outer cup and the inner cup, and a second chamber is formed inside the inner cup. A buffer pad is arranged between the ports of the outer cup and the inner cup. The needle holder is located above the negative pressure cup. A micro-needle body is arranged inside the needle holder. The micro-needle body is driven to extend downwards and contract through a telescopic mechanism. An outer connecting pipe and an inner connecting pipe for communicating with the interface ends of the two vacuum pumps are respectively arranged above the side walls of the outer cup and the inner cup.

[0009] Further, the outer cup comprises an outer cylinder and an outer plate. The outer plate is arranged at the upper end of the outer cylinder and is integrally structured. The inner cup comprises an inner cylinder and an inner plate. The inner plate is arranged at the upper end of the inner cylinder and is integrally structured. The needle holder is arranged between the outer plate and the inner plate, and its output end extends below the inner plate.

[0010] Further, a limiting strip is arranged on the outer side of the needle holder. Limiting grooves adapted to the limiting strip are opened on the inner plate and the outer plate. A support frame is slidably sleeved on the needle holder between the inner plate and the outer plate. The length of the limiting strip is adapted to the overall length of the inner plate, the support frame and the outer plate. A limiting plate adapted to the upper surface of the outer plate is arranged on the outer wall of the upper end of the needle holder. A threaded sleeve is threadedly connected to the outer wall of the lower end of the needle holder. The threaded sleeve is hermetically connected to the inner side of the inner plate. The two ends of the support frame are respectively hermetically assembled and connected to the inner plate and the outer plate. After the treatment is completed, the negative pressure cup can be disassembled and cleaned. Specifically, the threaded sleeve can be unscrewed, so that the inner cup and the needle holder slide apart, and then the support frame can be taken out. Finally, the needle holder can be separated from the outer cup for cleaning a certain component separately, avoiding the generation of cleaning dead corners and ensuring the cleaning quality.

[0011] Further, the buffer pad is arranged in a ring structure and a connecting ring is arranged above it. The inner ring and the outer ring of the connecting ring are respectively threadedly and hermetically connected to the inner cylinder and the outer cylinder. A plurality of positioning grooves are evenly opened on the buffer pad. The edges of the positioning grooves are all chamfered. When negative pressure is generated in the first chamber, the skin in contact with the buffer pad will be slightly pulled into the positioning grooves, realizing the positioning of the negative pressure cup on the skin.

[0012] Furthermore, the driving mechanism includes a tooth plate, a gear and a motor, the tooth plate is arranged at the upper end of the microneedle body, the motor is arranged above the outer plate through a bottom plate clamping, the motor output end is linked with a rotating shaft, the gear is linked with the outside of the rotating shaft, a groove is opened on one side of the needle holder, the side wall of the gear is meshed with the side edge of the tooth plate, the upper end of the tooth plate is assembled and connected with the upper part of the needle holder through a first spring, the rotating shaft is driven to rotate by driving the motor, and then the gear is driven to rotate, and the tooth plate moves up and down accordingly, thereby realizing the downward needle insertion and lifting operations of the microneedle body.

[0013] Furthermore, the length of the rotating shaft is longer than the diameter of the needle holder, the outer side of the rotating shaft is meshed and slidably arranged with the inner side of the gear, the combination of the toothed plate and the microneedle body is provided with a plurality and arranged in a left-right arrangement, the gear slides on the rotating shaft and corresponds to different toothed plate positions one by one, and when acupuncture is performed, the gear is moved to one side of a toothed plate to mesh with it, and the motor is driven to drive the toothed plate to move down and lift it up after the acupuncture is performed. After the treatment at one position is completed and the next position is moved to the next position for acupuncture, it may be contaminated by blood due to the previous microneedle body during acupuncture. When the next acupuncture is performed, the gear can be moved to another toothed plate position, and the motor can be driven to drive another clean microneedle body to move down for acupuncture treatment, which can save the labor of frequently replacing the needle holder during use and save treatment time. In addition, when installing and disassembling the needle holder, the gear can be moved to a position away from the needle holder to avoid the gear affecting the assembly and disassembly of the needle holder.

[0014] Furthermore, protective plates are rotatably provided on both sides of the upper part of the inner cup, and the upper part of the protective plates is assembled and connected to the inner cup by a torsion spring, and the lower ends of the two protective plates are fitted together, and the lower end of the needle holder is located above the two protective plates, and a pressure plate is provided on the sliding sleeve at the lower end of the tooth plate, and the pressure plate is assembled and connected to the tooth plate by a second spring. A rocker plate adapted to the pressure plate is provided on the inner side of the upper ends of the two protective plates, and the rocker plate is always located under the protective plates. Under the action of the torsion spring, the two protective plates are fitted with each other in the initial state to protect the needle holder inside. When the needle is inserted, the tooth plate moves downward, driving the pressure plate to move downward, and the microneedle body passes through between the two rocker plates. The pressure plate squeezes the two rocker plates to drive the two protective plates to rotate and open, and the microneedle body passes through the protective plate and moves downward for needle insertion. When the downward movement range is large, the second spring limits the pressure plate to prevent the pressure plate from moving too far downward with the tooth plate, causing the pressure plate to separate from the rocker plate.

[0015] Furthermore, a filter is provided on the inner side of the inner cup, and one end of the inner connecting tube connected to the second chamber is located between the filter and the inner cup. The filter can isolate the thrombus and blockages sucked out by negative pressure to prevent them from entering the vacuum pump and causing blockage in the vacuum pump, and only allow blood to flow through.

[0016] Further, spiral grooves are provided inside the outer plate. The number of turns of the spiral grooves is 4 - 5 turns. Both ends of the spiral grooves extend to the inner side of the outer plate. One end of the spiral grooves communicates with the outer connecting pipe. A membrane valve is provided inside one end of the spiral grooves facing the outer connecting pipe. By providing the relatively long spiral grooves and the membrane valve, the membrane valve first strictly limits the passing flow rate to the safety upper limit, avoiding an instant large pressure difference when the vacuum pump is turned on. When the gas is pumped by the vacuum pump, the gas passes through the spiral grooves to achieve speed limitation. Even if the pumping speed is large, the gas can only flow through little by little. In this way, when the cup is attached to the skin, the negative pressure will decrease gently, and the skin will only be gently lifted, hardly causing pain or bruising.

[0017] On the other hand, the present invention provides a method for using a traditional Chinese medicine micro - needle positioning negative pressure blood stasis removal device for treating blood stasis and blockage of meridians, including,

[0018] Step S1: Scan the target skin area with a thermal imaging device, and select the suspected blood stasis target points according to the thermal map;

[0019] Step S2: Take the negative pressure cup and place it at the target position, drive a vacuum pump to extract the gas in the first chamber, and the skin is negatively adsorbed and fixed through the positioning groove to achieve the positioning effect of the negative pressure cup;

[0020] Step S3: Drive the motor to drive the rotation of the rotating shaft, and then drive the rotation of the gear. The toothed plate and the micro - needle body move downward accordingly. The pressing plate presses two rocker plates to drive the rotation and opening of two protective plates. The micro - needle body moves downward through the protective plates to prick the skin located in the second chamber, and then lifts up. The protective plates reset to protect the micro - needle body;

[0021] Step S4: Drive another vacuum pump to perform a pulsed extraction of the gas in the second chamber through the inner connecting pipe. After the blood stasis is extracted, stop the negative pressure and relieve the pressure, and remove the negative pressure cup to complete one treatment;

[0022] Step S5: When treating different parts of the same patient, when the micro - needle body is contaminated by the blood during the previous treatment, turn the gear to other toothed plate positions, and at this time, drive the motor to drive another clean micro - needle body to move downward for acupuncture treatment;

[0023] Step S6: During cleaning, unscrew the buffer pad by rotation, unscrew the threaded sleeve, so that the inner cup slides and separates from the needle holder, and then take out the support frame. Finally, the needle holder can be separated from the outer cup for cleaning a certain component alone. Among them, the needle holder can be discarded as a disposable utensil, and a new needle holder is replaced. After cleaning, reassemble.

[0024] The beneficial effects of the present invention are:

[0025] The present invention constructs a dual-cavity structure of a low-negative-pressure positioning cavity and a high-negative-pressure desilting cavity between the outer cup and the inner cup. The outer cavity is evacuated at a limited speed through a spiral groove and a flow-limiting membrane valve, so that the skin is gently pulled up within 1-2 seconds to achieve painless fitting. The inner cavity is acted on the local skin with high negative pressure by another vacuum pump. The microneedle array is accurately inserted once and then withdrawn, ensuring that the channel is unobstructed and blood stasis is efficiently discharged. The needle holder is equipped with multiple groups of switchable microneedles, and the clean needle group can be replaced within the same course of treatment by turning the gear, reducing the artificial delay of frequent removal and replacement of the needle plate. It is also convenient to disassemble and clean, and can achieve the effect of cleaning without dead ends. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following will describe the detailed implementation manner of the present invention with reference to the accompanying drawings of the specification.

[0037] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0038] Secondly, as referred to herein, "one embodiment" or "embodiment" means a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0039] Please refer to Figures 1 - 7 , the present invention provides a technical solution: a traditional Chinese medicine microneedle positioning negative pressure blood stasis removal device for treating choroidal stasis and blockage, including a fixed seat 1 and a negative pressure cup 2. The negative pressure cup 2 is detachably arranged on the fixed seat 1. The fixed seat 1 is provided with two vacuum pumps 4 for communicating with the negative pressure cup 2. The negative pressure cup 2 includes an outer cup 511, an inner cup 512, and a needle holder 513. The outer cup 511 is sleeved outside the inner cup 512 and has an opening facing downwards. A first chamber 514 is formed between the outer cup 511 and the inner cup 512. A second chamber 515 is formed inside the inner cup 512. A buffer pad 6 is provided between the ports of the outer cup 511 and the inner cup 512. The needle holder 513 is located above the middle of the negative pressure cup 2. A microneedle body 7 is arranged inside the needle holder 513. The microneedle body 7 is driven to extend downward and retract through a telescopic mechanism. An outer connecting pipe 811 and an inner connecting pipe 812 for communicating with the interface ends of the two vacuum pumps 4 are respectively arranged above the side walls of the outer cup 511 and the inner cup 512.

[0040] AsFigures 1 - 7 As shown in the figure, the outer cup 511 includes an outer cylinder 911 and an outer plate 912. The outer plate 912 is arranged at the upper end of the outer cylinder 911 and is integrally structured. The inner cup 512 includes an inner cylinder 914 and an inner plate 913. The inner plate 913 is arranged at the upper end of the inner cylinder 914 and is integrally structured. The needle holder 513 is arranged between the outer plate 912 and the inner plate 913, and its output end extends below the inner plate 913.

[0041] As Figures 1 - 7 As shown in the figure, a limiting strip 101 is arranged on the outer side of the needle holder 513. Limiting grooves 102 adapted to the limiting strip 101 are formed on the inner plate 913 and the outer plate 912. A support frame 103 is slidably sleeved on the needle holder 513 between the inner plate 913 and the outer plate 912. The length of the limiting strip 101 is adapted to the overall length of the inner plate 913, the support frame 103 and the outer plate 912. A limiting plate 104 adapted to the upper surface of the outer plate 912 is arranged on the outer wall of the upper end of the needle holder 513. A threaded sleeve 105 is threadedly connected to the outer wall of the lower end of the needle holder 513. The threaded sleeve 105 is hermetically connected to the inner side of the inner plate 913. Both ends of the support frame 103 are hermetically assembled and connected to the inner plate 913 and the outer plate 912 respectively. After the treatment is over, the negative pressure cup 2 can be disassembled and cleaned. Specifically, the threaded sleeve 105 can be unscrewed, so that the inner cup 512 slides and separates from the needle holder 513, and then the support frame 103 can be taken out. Finally, the needle holder 513 can be separated from the outer cup 511, so as to clean a certain component separately, avoid the generation of cleaning dead corners, and ensure the cleaning quality.

[0042] As Figures 1 - 7 As shown in the figure, the buffer pad 6 is arranged in a ring structure and a connecting ring 111 is arranged above it. The inner ring and the outer ring of the connecting ring 111 are threadedly and hermetically connected to the inner cylinder 914 and the outer cylinder 911 respectively. A plurality of positioning grooves 112 are evenly formed on the buffer pad 6. The edges of the positioning grooves 112 are all chamfered. When negative pressure is generated in the first chamber 514, the skin in contact with the buffer pad 6 will be slightly pulled into the positioning grooves 112, realizing the positioning of the negative pressure cup 2 on the skin.

[0043] As Figures 1 - 7 As shown in the figure, the driving mechanism includes a toothed plate 121, a gear 122 and a motor 123. The toothed plate 121 is arranged at the upper end of the microneedle body 7. The motor 123 is clamped above the outer plate 912 through a bottom plate 124. A rotating shaft 125 is linked to the output end of the motor 123. The gear 122 is linked to the outside of the rotating shaft 125. A groove is formed on one side of the needle holder 513. The side wall of the gear 122 meshes with the side of the toothed plate 121. The upper end of the toothed plate 121 is assembled and connected to the upper part inside the needle holder 513 through a first spring 126. By driving the motor 123 to drive the rotating shaft 125 to rotate, the gear 122 is driven to rotate, and the toothed plate 121 moves up and down accordingly, realizing the downward needle insertion and lifting operations of the microneedle body 7.

[0044] As Figures 1 - 7As shown, the length of the rotating shaft 125 is longer than the diameter of the needle holder 513. The outer side of the rotating shaft 125 is meshed and slidably arranged with the inner side of the gear 122. There are multiple combinations of the toothed plate 121 and the microneedle body 7, which are arranged side by side left and right. The gear 122 slides on the rotating shaft 125 and corresponds to the positions of different toothed plates 121 one by one. When inserting the needle, the gear 122 is toggled to one side of a toothed plate 121 and meshed with it. After the motor 123 drives the toothed plate 121 to move down for needle insertion and then lift up, when moving to the next part for needle insertion after the treatment at one position is completed, it may be contaminated because the previous microneedle body 7 was contaminated with blood during needle insertion. When performing the next needle insertion, the gear 122 can be toggled to the position of other toothed plates 121. At this time, driving the motor 123 can drive another clean microneedle body 7 to move down for needle insertion treatment, which can save the labor of frequently replacing the needle holder 513 during use and can save the treatment time. In addition, when installing and disassembling the needle holder 513, the gear 122 can be toggled to a position away from the needle holder 513 to avoid the influence of the gear 122 on the disassembly and assembly of the needle holder 513.

[0045] As Figures 1 - 7 shown, on both sides above the inner cup 512, there are rotatably arranged protective plates 131. The upper part of the protective plates 131 is assembled and connected with the inner cup 512 through torsion springs. The lower ends of the two protective plates 131 are in contact with each other. The lower end of the needle holder 513 is located above the two protective plates 131. The lower end of the toothed plate 121 is slidably sleeved with a pressing plate 132. The pressing plate 132 is assembled and connected with the toothed plate 121 through a second spring 133. On the inner sides of the upper ends of the two protective plates 131, there is a rocker 134 adapted to the pressing plate 132. The rocker 134 is always located below the protective plate 131. Under the action of the torsion spring, the two protective plates 131 are in a state of mutual contact initially, protecting the needle holder 513 inside. When inserting the needle, the toothed plate 121 moves down, driving the pressing plate 132 to move down. The microneedle body 7 passes through between the two rockers 134. The pressing plate 132 presses the two rockers 134 to drive the two protective plates 131 to rotate and open. The microneedle body 7 passes through the protective plate 131 and moves down for needle insertion. When the downward movement range is relatively large, the limit of the second spring 133 on the pressing plate 132 can prevent the pressing plate 132 from moving down with the toothed plate 121 too much, resulting in the situation that the pressing plate 132 is separated from the rocker 134.

[0046] As Figures 1 - 7 shown, a filter screen 14 is provided on the inner side of the inner cup 512. One end of the inner connecting pipe 812 connected to the second chamber 515 is located between the filter screen 14 and the inner cup 512. Through the provided filter screen 14, the thrombus and congestion substances sucked out by negative pressure can be isolated to avoid the problem of blockage in the vacuum pump 4 caused by their entry into the vacuum pump 4, and only allow blood to flow through.

[0047] As Figures 1 - 7As shown, a spiral groove 151 is provided inside the outer plate 912, and the number of turns of the spiral groove 151 is 4-5 turns. Both ends of the spiral groove 151 extend to the inner side of the outer plate 912, and one end of the spiral groove 151 is connected to the external connecting pipe 811. A membrane valve 152 is provided inside the spiral groove 151 at one end facing the external connecting pipe 811. By setting a longer section of the spiral groove 151 and the membrane valve 152, the membrane valve 152 firstly strictly limits the flow rate to the safety upper limit to avoid an instantaneous large pressure difference as soon as the vacuum pump 4 is turned on. When the vacuum pump 4 is used to evacuate air, the gas reaches the speed limit through the spiral groove 151. Even if the evacuation speed is increased, the gas can only flow through a little bit. In this way, when the cup is attached to the skin, the negative pressure will drop smoothly, and the skin will only be gently pulled up, which is almost painless and not easy to cause bruises.

[0048] Working principle:

[0049] Step S1, scanning the target skin area with a thermal imaging device, and selecting a suspected blood stasis target point based on the thermal image;

[0050] Step S2, taking the negative pressure cup 2 and placing it at the target position, driving a vacuum pump 4 to extract the gas in the first chamber 514, and the skin is fixed by negative suction through the positioning groove 112, so as to achieve the positioning effect of the negative pressure cup 2;

[0051] Step S3, the motor 123 is driven to drive the rotating shaft 125 to rotate, and then the gear 122 is driven to rotate, and the tooth plate 121 and the microneedle body 7 move downward, and the pressing plate 132 squeezes the two rockers 134 to drive the two protective plates 131 to rotate and open, and the microneedle body 7 passes through the protective plates 131 and moves downward to acupuncture the skin in the second chamber 515, and then lifts up, and the protective plates 131 are reset to protect the microneedle body 7;

[0052] Step S4, drive another vacuum pump 4 to extract the gas in the second chamber 515 in a pulsed manner through the internal connecting tube 812, stop the negative pressure and release the pressure after the blockage is completely extracted, and remove the negative pressure cup 2 to complete one treatment;

[0053] Step S5, when treating different parts of the same patient, if the microneedle body 7 is contaminated by blood in the previous treatment, the gear 122 is moved to another position of the tooth plate 121, and the motor 123 is driven to drive another clean microneedle body 7 to move downward for acupuncture treatment;

[0054] Step S6, when cleaning, rotate and unscrew the buffer pad 6, unscrew the threaded sleeve 105, so that the inner cup 512 and the needle holder 513 slide apart, and then take out the support frame 103. Finally, the needle holder 513 can be separated from the outer cup 511 for cleaning a certain component separately. The needle holder 513 can be discarded as a disposable device, replaced with a new needle holder 513, and reassembled after cleaning.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
