Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an automatic bloodletting and cupping device. Background Technology

[0002] Bloodletting therapy is a common treatment method in Traditional Chinese Medicine (TCM) and is widely used in modern acupuncture clinical practice. It can be applied to the treatment of various diseases in internal medicine, surgery, ENT, dermatology, pediatrics, and gynecology. Bloodletting cupping therapy combines bloodletting and cupping. It involves pricking blood at acupoints or stagnant blood vessels, followed by cupping, to promote the discharge of stagnant blood, regulate the flow of Qi in the internal organs, and ensure smooth circulation of Qi and blood. It has the effects of dispersing blood stasis, reducing swelling, lowering fever, and relieving pain. It can be used for excess syndromes and heat syndromes, playing a role in unblocking meridians, removing blood stasis, and promoting new blood production.

[0003] Currently, the commonly used bloodletting and cupping therapy in clinical practice involves disinfecting the acupoints or meridians, pricking them with a three-edged needle, manually applying a cupping jar, and then manually removing the jar and cleaning the blood. This procedure is complex and has many adverse clinical reactions, including the following problems: The needling force and depth are uncontrollable, easily leading to adverse reactions. Due to differences in operator skill, poor control of needling force and depth can cause treatment pain and potential risks at dangerous sites, such as pneumothorax if performed improperly in the intercostal region.

[0057] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0058] The commonly used bloodletting and cupping therapy in clinical practice currently has the following problems:

[0059] ① The needling force and depth are uncontrollable and can easily lead to adverse reactions: Due to the differences in operation between different operators, when using a three-edged needle for puncture, there is a risk of treatment pain and dangerous sites caused by poor control of needling force and depth. For example, improper intercostal manipulation may cause pneumothorax.

[0060] ② The pressure of cupping is uncontrollable. Excessive pressure often leads to blisters and excessive bleeding, while insufficient pressure has no therapeutic effect: This therapy requires cupping after the three-edged needle pricking operation. The pressure during cupping cannot be controlled. Excessive pressure can easily damage the skin of the elderly and children, while insufficient pressure can easily reduce the therapeutic effect.

[0061] ③ Cupping procedures are prone to causing fires, and the sterilization of the cups is often inadequate: Operators need to ignite the cups during the procedure, which can easily lead to burns or even fires due to improper handling. During the interval between bloodletting and cupping, the bleeding site is exposed to the routine clinic environment, increasing the risk of iatrogenic infection. Furthermore, glass cups are often repeatedly sterilized before use. Currently, clinical practice typically uses disinfectants such as acetone for soaking and sterilization, which may not be thorough. If the cups come into contact with the bleeding site on the skin, it can easily lead to iatrogenic infection.

[0062] ④ After cupping, clinicians often go to treat other patients. Due to their busy work, they may forget the time to remove the cups, which may lead to excessive blood loss and cause disputes or even medical malpractice incidents.

[0063] ⑤ After cupping, local blood stains need to be cleaned manually with medical cotton balls, as there is a risk of infectious diseases being transmitted through blood.

[0064] Due to the aforementioned operational limitations, the clinical application and promotion of this therapy are greatly restricted. This embodiment provides an automatic bloodletting and cupping device, which can effectively solve the above problems.

[0065] See Figures 1-4 As shown, the automatic bloodletting and cupping device provided in this embodiment includes a body 100 and a cup 200; the cup 200 is detachably connected to the body 100. For example, the cup 200 is a disposable item, which can effectively solve the potential infection risk caused by incomplete cup disinfection in the prior art, and can effectively ensure that the disinfection of the cup 200 meets the sterility requirements.

[0066] The body 100 includes a housing 110, a driver 120, a negative pressure connecting rod 140, and a ejection rod 150; the driver 120 is located inside the housing 110, and the negative pressure connecting rod 140 is connected to the housing 110.

[0067] The drive end of the driver 120 extends into the interior of the negative pressure connecting rod 140; the ejector rod 150 is disposed inside the negative pressure connecting rod 140, and an ejector elastic element 141 is connected between the head end of the ejector rod 150 and the drive end of the driver 120; that is, the ejector elastic element 141 is located inside the negative pressure connecting rod 140.

[0068] The canister 200 includes a canister body 210, a support rod 220, an impact moving rod 230, and a lancet 240. The support rod 220 is fixedly connected to the canister body 210 and passes through the inner and outer walls of the canister body 210. A portion of the impact moving rod 230 is slidably connected inside the support rod 220, and the tail end of the impact moving rod 230 extends out of the support rod 220 and is fixedly connected to the lancet 240, which is located inside the canister body 210.

[0069] The support rod 220 and the negative pressure connecting rod 140 are detachably and sealed together, and the tail end of the ejection rod 150 can abut against the impact moving rod 230.

[0070] The ejector elastic element 141 is configured to be compressed and generate elastic deformation when the drive end of the driver 120 moves. After the ejector elastic element 141 is compressed to a preset elastic deformation size, it can drive the ejector rod 150 to move inside the negative pressure connecting rod 140, thereby driving the impact moving rod 230 to move, and then driving the lancet 240 to move.

[0071] The negative pressure connecting rod 140 is internally equipped with a limiting member 142 to restrict the movement distance of the ejector rod 150, thereby limiting the movement distance of the impact moving rod 230 and the lancet 240. It should be noted that when the ejector elastic member 141 drives the ejector rod 150 to move within the negative pressure connecting rod 140, the limiting member 142 restricts the movement distance of the ejector rod 150, thus ensuring that the impact moving rod 230 moves a preset distance, and consequently, that the lancet 240 moves a preset distance, ensuring that the force and depth of the lancet 240 are basically consistent each time it is automatically ejected. For example, when the driving end of the driver 120 moves downward and presses down on the ejector elastic member 141, the ejector elastic member 141 is compressed to a preset elastic deformation size, driving the ejector rod 150 to move downward to the limiting member 142, thereby driving the impact moving rod 230 to move downward a preset distance, and consequently, driving the lancet 240 to move downward a preset distance.

[0072] Optionally, the ejector elastic element 141 is a spring or other elastic element.

[0073] Alternatively, the driver 120 can be a diaphragm pump or other DC pump.

[0074] Optionally, the limiting member 142 and the ejector rod 150 are interference-fitted, and the ejector rod 150 can move along the limiting member 142. Through the interference fit between the limiting member 142 and the ejector rod 150, a certain static friction force exists between them. When the actual elastic deformation of the ejector elastic member 141 is less than the preset elastic deformation, this static friction force acts on the ejector rod 150 and can offset at least part of the force from the ejector elastic member 141 acting on the ejector rod 150, thereby keeping the ejector rod 150 stationary and storing energy for its ejection.

[0075] The specific operation scheme of the automatic bloodletting and cupping device described in this embodiment is as follows: The cup 200 is installed on the machine body 100, and the operator holds the machine body 100 and places the cup 200 on the skin of the human body at the treatment site, especially so that the position of the bloodletting needle 240 corresponds to the treatment site. The operator holds the machine body 100, for example, by holding the housing 110.

[0076] In some embodiments, the negative pressure connecting rod 140 is disposed inside the housing 110, such as... Figure 1 and Figure 3 Alternatively, the negative pressure connecting rod 140 may be disposed outside the housing 110, such as... Figure 4 ; those skilled in the art can also make Figure 4 The negative pressure connecting rod 140 shown is surrounded by a housing 110. The specific connection position between the negative pressure connecting rod 140 and the housing 110 can be determined according to requirements.

[0077] The automatic bloodletting and cupping device described in this embodiment includes a body 100 and a cup body 200. The body 100 includes a housing 110, a driver 120, a negative pressure connecting rod 140, and a catapult rod 150. The cup body 200 includes a cup body 210, a support rod 220, an impact moving rod 230, and a bloodletting needle 240. The driver 120 moves to compress the catapult elastic element 141 and generate elastic deformation. After the catapult elastic element 141 is compressed to a preset elastic deformation size, it can drive the catapult rod. The ejector rod 150 moves within the negative pressure connecting rod 140, thereby driving the impact moving rod 230 to move, which in turn drives the bloodletting needle 240 to move, achieving automatic ejection of the bloodletting needle 240. The force of the bloodletting needle 240 is essentially consistent with each automatic ejection. A limiting member 142 inside the negative pressure connecting rod 140 restricts the movement distance of the ejector rod 150, thus limiting the movement distance of the impact moving rod 230 and the bloodletting needle 240. This ensures that the puncture depth of the bloodletting needle 240 is essentially consistent with each automatic ejection. This automatic bloodletting and cupping device achieves automatic ejection of the bloodletting needle 240, exhibiting good stability. The puncture force and depth of the bloodletting needle 240 remain essentially constant with each ejection, effectively solving the problem of uncontrollable puncture force and depth caused by differences in operator skill.

[0078] Currently, cupping therapy often involves manually igniting a flame to create negative pressure inside the cup. This process is complex and has poor safety. The negative pressure created by manual ignition is uncontrollable, often causing skin damage and blisters due to excessive negative pressure. There is also the risk of burns to patients or even fires during ignition. To address these issues, see [link to relevant documentation]. Figures 1-4 As shown, in an optional embodiment, the body 100 further includes a negative pressure vacuum pump 130; the negative pressure vacuum pump 130 is internally connected to the negative pressure connecting rod 140 and is configured to extract gas from inside the negative pressure connecting rod 140.

[0079] The ejection rod 150 includes an ejection cavity 151 and an ejection through hole 152; the ejection through hole 152 connects the ejection cavity 151 with the interior of the negative pressure connecting rod 140; optionally, the number of ejection through holes 152 is one or more, and the multiple ejection through holes 152 can be arranged along the axial or circumferential direction of the ejection rod 150.

[0080] The impact moving rod 230 has a canister air passage that connects to the inner cavity of the canister body 210. For example, the impact moving rod 230 has a through hole near the lancet 240, or the tail end of the impact moving rod 230 has a through hole that connects the canister air passage to the inner cavity of the canister body 210; wherein the tail end of the impact moving rod 230 is connected to the lancet 240.

[0081] Optionally, the first end of the impact moving rod 230 has a floating valve 231 that blocks the gas passage of the tank. When the ejector rod 150 abuts against the impact moving rod 230, the floating valve 231 is located inside the ejection chamber 151. The floating valve 231 is configured to move away from the tank body 210 under the negative pressure driven by the negative pressure of the negative pressure vacuum pump 130 to open the gas passage of the tank. For example, when the negative pressure vacuum pump 130 extracts the gas inside the negative pressure connecting rod 140, it first extracts the negative pressure. The gas between the connecting rod 140 and the outer wall of the ejector rod 150 is then drawn into the ejection chamber 151 inside the ejector rod 150 through the ejection through-hole 152, putting the ejection chamber 151 into a negative pressure state. As the negative pressure vacuum pump 130 continues to draw gas, the floating valve 231 moves away from the canister body 210 under the negative pressure and opens the canister gas passage to draw gas from the inner cavity of the canister body 210, thus putting the inner cavity of the canister body 210 into a negative pressure state. Optionally, after the canister body 210 leaves the machine body 100, because the inner cavity of the canister body 210 is in a negative pressure state, the negative pressure suction of the inner cavity of the canister body 210 drives the floating valve 231 to move towards the canister body 210 to close the canister gas passage.

[0082] Optionally, in some embodiments, the floating valve 231 opens the canister air passage under negative pressure, so that the inner cavity of the canister body 210 is in a negative pressure state. Then, the driving end of the actuator 120 moves and drives the ejector elastic element 141 to produce elastic deformation. When the actual elastic deformation size of the ejector elastic element 141 reaches the preset elastic deformation size, the ejector elastic element 141 drives the ejector rod 150 to eject within the negative pressure connecting rod 140, thereby driving the impact moving rod 230 to move, and then driving the lancet 240 to move. After the ejector rod 150 ejects, the driving end of the actuator 120 can quickly return to its original position, removing the force on the ejector elastic element 141.

[0083] like Figure 2As shown, optionally, the floating valve 231 includes a ball portion located at its top, which is outside the impact moving rod 230, and the ball portion can be sealed to the impact moving rod 230 to close the tank air passage. Optionally, the inner wall of the first end of the impact moving rod 230 is provided with a venting structure 235, for example, the venting structure 235 is a mesh, and the bottom end of the floating valve 231 can abut against part of the venting structure 235, at which time the tank air passage is in the open state; through the venting structure 235, the air passage can be ensured to be connected, and the floating valve 231 can be restricted to prevent the floating valve 231 from detaching from the impact moving rod 230.

[0084] The automatic bloodletting and cupping device described in this embodiment uses a negative pressure vacuum pump 130 to extract gas from inside the negative pressure connecting rod 140, and then extracts gas from the inner cavity of the cup body 210, so that the inner cavity of the cup body 210 is in a negative pressure state. This can effectively avoid the problems of complicated operation and poor safety caused by manually igniting to create negative pressure inside the cup.

[0085] See Figure 1 and Figure 2 As shown, in an optional embodiment, the tank 200 further includes an impact elastic element 250 disposed inside the support rod 220; the impact elastic element 250 is connected to the impact moving rod 230, and the impact elastic element 250 has an elastic deformation that drives the impact moving rod 230 to extend out of the support rod 220; through the impact elastic element 250, the impact moving rod 230 can be driven to reset, thereby driving the lancet 240 to reset. For example, the ejector rod 150 ejects and moves inside the negative pressure connecting rod 140 to drive the impact moving rod 230 to move, thereby driving the lancet 240 to move, while also causing the impact elastic element 250 to produce an elastic deformation that drives the impact moving rod 230 to extend out of the support rod 220; when the driving end of the driver 120 retracts to the original position, the impact moving rod 230 and the lancet 240 reset under the elastic action of the impact elastic element 250.

[0086] Optionally, the impact moving rod 230 is provided with an impact limiting part 232; the impact limiting part 232 is located inside the support rod 220, and the impact limiting part 232 can abut against the end of the support rod 220 away from the lancet 240. The impact limiting part 232 is used to limit the position of the impact moving rod 230 extending out of the support rod 220 to prevent the impact moving rod 230 from disengaging from the support rod 220, and can further limit the reset position of the lancet 240, so that the lancet 240 can be reset to a preset position.

[0087] Optionally, the impact elastic element 250 is a spring or other elastic element.

[0088] See Figure 2As shown, in an optional embodiment, the impact moving rod 230 includes an impact part 233 and a connecting part 234 connected together. For example, the impact part 233 and the connecting part 234 are integrally formed, or the impact part 233 and the connecting part 234 are connected by welding or other methods.

[0089] A floating valve 231 is disposed at the end of the impact portion 233 away from the connecting portion 234; that is, the floating valve 231 is movably connected to the end of the impact portion 233. For example, under the negative pressure driven by the negative pressure of the negative pressure vacuum pump 130, the floating valve 231 moves away from the can body 210, so that the ball portion of the floating valve 231 moves away from the impact portion 233 and opens the can air passage; after the can body 210 leaves the machine body 100, since the inner cavity of the can body 210 is in a negative pressure state, the negative pressure suction of the inner cavity of the can body 210 drives the floating valve 231 to move towards the can body 210, so that the ball portion of the floating valve 231 abuts against and seals the impact portion 233 and closes the can air passage.

[0090] Optionally, the lancet 240 is disposed at the end of the connecting portion 234 away from the impact portion 233; for example, the lancet 240 and the connecting portion 234 are fixedly connected by welding, screwing or other methods.

[0091] Optionally, a portion of the impact portion 233 and a portion of the connecting portion 234 are both located inside the support rod 220; the impact limiting portion 232 is provided on the outer wall of the impact portion 233; optionally, the impact limiting portion 232 is welded to the impact portion 233.

[0092] Optionally, the gas passage passes through the impact part 233 and the connecting part 234 in sequence;

[0093] Optionally, the outer diameter of the impact part 233 is larger than the outer diameter of the connecting part 234; the impact elastic member 250 is sleeved on the connecting part 234, and one end of the impact elastic member 250 is connected to the end of the impact part 233, and the other end is connected to the end of the support rod 220 near the lancet 240.

[0094] Optionally, the impact elastic member 250 has an elastic deformation that causes the impact part 233 to extend out of the support rod 220. The impact elastic member 250 can drive the impact part 233 to reset, that is, drive the impact moving rod 230 to reset, and then drive the lancet 240 to reset.

[0095] See Figure 1 , Figure 3 and Figure 4As shown, in an optional embodiment, a reset elastic member 143, which is sleeved on the ejector rod 150, is provided inside the negative pressure connecting rod 140.

The reset elastic member 143 is configured to be compressed when the ejector elastic member 141 drives the ejector rod 150 to move, and to generate an elastic deformation that drives the ejector rod 150 to reset. The reset elastic member 143 enables the ejector rod 150 to reset. For example, the ejector rod 150 is ejected and moved inside the negative pressure connecting rod 140 to drive the reset elastic member 143 to generate an elastic deformation that drives the ejector rod 150 to reset; when the driving end of the driver 120 returns to its original position, the ejector rod 150 resets under the elastic action of the reset elastic member 143.

[0096] Optionally, the reset elastic element 143 is a spring or other elastic element.

[0097] See Figure 1 , Figure 3 and Figure 4 As shown, in an optional embodiment, the drive end of the driver 120 is fixedly connected to a guide rod 121, and the ejector elastic member 141 is sleeved on the guide rod 121; the guide rod 121 guides the ejector elastic member 141 during its elastic deformation.

[0098] Optionally, the tail end of the guide rod 121 extends into the interior of the ejector rod 150, and the guide rod 121 is slidably connected to the ejector rod 150. The slidable connection between the tail end of the guide rod 121 and the ejector rod 150 allows for better placement of the ejector elastic element 141 between the head end of the ejector rod 150 and the drive end of the driver 120.

[0099] See Figure 1 and Figure 2 As shown, in an optional embodiment, a sealing plug 260 is provided between the support rod 220 and the tank body 210; the sealing plug 260 improves the sealing performance between the support rod 220 and the tank body 210. Optionally, the sealing plug 260 is a rubber plug, a silicone plug, or other structure.

[0100] Optionally, the 240 bloodletting needle can be a triangular needle or other needles.

[0101] See Figure 1 As shown, optionally, at least a portion of the inner wall of the can body 210 is connected to a liquid-absorbing element 270 for absorbing liquid; by absorbing liquid, such as blood, through the liquid-absorbing element 270, the probability of liquid residue on the skin surface is reduced, and the probability of manually applying medical cotton balls to clean local blood stains after the can is removed can be avoided or reduced, which can effectively reduce the risk of infectious diseases being transmitted through blood.

[0102] Optionally, the absorbent component 270 includes an expandable sponge or other absorbent material. By using an expandable sponge, it can expand rapidly when absorbing blood, which helps reduce the probability of blood remaining on the skin surface.

[0103] Optionally, the negative pressure connecting rod 140 is provided with a sealing element 144 that is sealingly connected to the support rod 220, and the support rod 220 can pass through the sealing element 144 and extend into the negative pressure connecting rod 140. The sealing element 144 is used to improve the sealing performance between the negative pressure connecting rod 140 and the support rod 220.

[0104] Alternatively, the seal 144 may be a rubber component, a silicone component, or other structure.

[0105] See Figure 1 , Figure 3 and Figure 4 As shown, in an optional embodiment, the automatic bloodletting and cupping device further includes a controller 300, a ejection confirmation element 400, and a pressure regulating element 500; the controller 300 is disposed inside the housing 110, and the ejection confirmation element 400 and the pressure regulating element 500 are respectively disposed on the housing 110.

[0106] The driver 120, the negative pressure vacuum pump 130, the ejection confirmation element 400, and the pressure regulating element 500 are electrically connected to the controller 300. The controller 300 is configured to receive confirmation information from the ejection confirmation element 400 and correspondingly control the circuit connection of the driver 120. For example, the confirmation information from the ejection confirmation element 400 is that the operator presses the ejection confirmation element 400. The controller 300 receives the confirmation information and connects the circuit of the driver 120 to drive the drive end of the driver 120 to move, thereby driving the ejection elastic element 141 to be compressed and generate elastic deformation. After the ejection elastic element 141 is compressed to the preset elastic deformation size, it can drive the ejection rod 150 to move inside the negative pressure connecting rod 140, thereby driving the impact moving rod 230 to move, and then driving the lancet 240 to move, realizing the automatic ejection of the lancet 240.

[0107] The controller 300 is also configured to receive pressure level information from the pressure regulator 500 and correspondingly control the negative pressure vacuum pump 130. For example, when the operator selects an appropriate pressure level on the pressure regulator 500 according to the patient's needs, the controller 300 receives this pressure level information and correspondingly controls the negative pressure vacuum pump 130 to achieve the negative pressure corresponding to the pressure level information inside the negative pressure connecting rod 140, thereby achieving the corresponding negative pressure inside the canister body 210, effectively controlling the negative pressure inside the canister body 210. By using different pressure levels on the pressure regulator 500, the negative pressure needs of different patients can be accommodated.

[0108] Optionally, the ejection confirmation element 400 is a push-button switch.

[0109] Optionally, the pressure regulating element 500 is a two-level pressure regulating button, a three-level pressure regulating button, or other pressure regulating buttons with different numbers of levels.

[0111] In an optional embodiment, a timer and an alarm are connected to the housing 110 and electrically connected to the controller 300. The timer is located inside the housing 110, and the alarm is located inside or on the housing 110. The controller 300 is configured to receive the timeout information from the timer and correspondingly control the alarm circuit to connect. Through the timer and the alarm, the operator or user can be reminded of the time to remove the cups when the cupping is finished.

[0112] See Figure 1 , Figure 3 and Figure 4 As shown, in an optional embodiment, an energy storage structure 700 electrically connected to the controller 300 is connected to the housing 110; the energy storage structure 700 is disposed on the housing 110 and configured to supply energy to the controller 300; the energy storage structure 700 supplies energy to the controller 300, that is, supplies energy to the automatic bloodletting and cupping device.

[0113] Optionally, the energy storage structure 700 includes a charging power supply and / or a battery box; the battery box can be used to house dry cell batteries.

[0114] In this embodiment, the controller 300 may be one or more of the following: STM32 chip, DRV8833 chip, NE555 chip, ESP32 chip, and Arduino Nano; the structural features, working principle, and specific circuit structure of the chip and its external electrical connection are all based on existing technology and will not be described in detail here.

[0115] For example, in the automatic bloodletting and cupping device described in this embodiment, the controller 300 uses a DRV8833 chip to realize the three-level negative pressure variation and automatic stop function of the pressure regulator 500. It achieves three different gradients of negative pressure control—25Kpa-35Kpa, 35Kpa-45Kpa, and 45Kpa-55Kpa—through different current intensities. The pressure is displayed on the screen of the digital pressure gauge 600 via the negative pressure connecting rod 140. The DRV8833 chip has the following advantages: 1. High efficiency and low power consumption, suitable for medical devices requiring precise control; 2. High output current: The DRV8833 can provide higher output current, ensuring stable motor operation at different speeds; 3. Built-in protection functions: The DRV8833 has short-circuit protection, overcurrent protection, and overheat protection functions, improving system safety; 4. Easy control: The control pins of the DRV8833 are simple, and multi-level control can be easily achieved through a microcontroller. For example, the DRV8833 chip, as a motor driver chip, has the following circuit connections: AIN1 and AIN2 are connected to the digital output pins of the microcontroller (such as D2 and D3); AOUT1 and AOUT2 are connected to the driver 120 (e.g., a DC motor); the VCC pin is connected to the power supply (e.g., 2.7V to 10.8V); the GND pin is connected to the power ground; and the ENABLE pin is connected to the PWM pin of the microcontroller to control the speed of the driver 120. This motor driver chip can achieve three different gradients of negative pressure control—25Kpa-35Kpa, 35Kpa-45Kpa, and 45Kpa-55Kpa—through different current intensities. The pressure is displayed on the screen of the digital pressure gauge 600 via the negative pressure connecting rod 140.

[0116] For example, in the automatic bloodletting and cupping device described in this embodiment, the controller 300 uses an ESP32 chip or an Arduino Nano as a microcontroller to control the driving of the driver 120 and the pressure reading of the digital pressure gauge 600. The microcontroller circuit connections are as follows: the VCC pin is connected to the microcontroller's 3.3V / 5V power supply; the GND pin is connected to the microcontroller's GND; and the output pin is connected to the microcontroller's analog input pin.

[0117] For example, the automatic bloodletting and cupping device described in this embodiment uses an MPXV7002DP as a pressure sensor, for example, the MPXV7002DP is connected to the analog input pin of the microcontroller.

[0118] The automatic bloodletting and cupping device provided in this embodiment uses a negative pressure vacuum pump 130 to extract gas from inside the negative pressure connecting rod 140, and then extracts gas from inside the cupping body 210, so that the cupping body 210 is in a negative pressure state. The driver 120 drives the ejector elastic element 141 to be compressed and generate elastic deformation, thereby driving the ejector rod 150 to move inside the negative pressure connecting rod 140, thereby driving the impact moving rod 230 and the bloodletting needle 240 to move, realizing the automatic ejection of the bloodletting needle 240. The bloodletting needle 240 automatically ejects and can pierce the skin. Then, when the driving end of the driver 120 automatically and quickly retracts to the original position, the impact moving rod 230 and the bloodletting needle 240 quickly retract and reset under the elastic action of the impact elastic element 250, realizing one blood collection. The automatic bloodletting and cupping device described in this embodiment uses electrically controlled negative pressure for cupping and bloodletting treatment, achieving full automation. For example, it can automatically apply negative pressure, automatically insert needles, and automatically draw blood. The operator only needs to press the ejection confirmation button 400 to complete the bloodletting and cupping treatment, making it easy to operate. It is also beneficial for studying various parameters of bloodletting and cupping therapy, such as the effects of different negative pressure values, different needle tip shapes, and different needle depths on the amount of blood released, and for evaluating the application safety and skin damage of each parameter, providing standardized data for clinical practice.

[0119] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
