[0002] Bloodletting therapy is a commonly used treatment method in traditional Chinese medicine. It is widely used in modern acupuncture clinics and can be applied to the treatment of various diseases such as internal medicine, surgery, ENT, dermatology, pediatrics, and gynecology. Bloodletting therapy with bloodletting and cupping is a combination of bloodletting and cupping therapy. It is to puncture bloodletting at acupoints or blood vessels, and then supplemented with cupping to promote the discharge of blood stasis, so that the internal organs can flow smoothly and the blood can flow smoothly. It has the effects of dispersing blood stasis, reducing swelling, reducing fever and relieving pain. It can be used for solid syndrome and heat syndrome to play a therapeutic role in dredging meridians, removing blood stasis and promoting new blood.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0058] The current common clinical practice of bloodletting with cupping has the following problems:

[0059] ① The force and depth of acupuncture are uncontrollable, which can easily lead to adverse reactions: Due to the differences in the operations of different operators, when using a three-edged needle for acupuncture, there is a risk of pain caused by poor control of the force and depth of acupuncture and possible risks of dangerous parts, such as the risk of pneumothorax caused by improper intercostal operation.

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

[0061] ③ Cupping is prone to fire, and the disinfection of the cup body often does not meet the requirements: the operator needs to ignite the cupping, which often causes burns to the patient or even fires due to improper operation. In the time interval between bloodletting and cupping, the bleeding site is exposed to the daily clinic environment, which is prone to cause the risk of iatrogenic infection. In addition, glass jars are often used after repeated disinfection. At present, clinical practice usually uses disinfectants such as Jianzhisu for soaking disinfection, which is not thorough. The cup body is prone to cause iatrogenic infection after contacting the bleeding site of the skin.

[0062] ④ After completing cupping, clinicians often go to treat other patients. Due to their busy work, they are prone to forget the time to remove the cupping. Failure to remove the cupping in time may lead to excessive blood release, which may in turn cause disputes or even medical malpractice.

[0063] ⑤ After removing the cup, local blood stains need to be cleaned manually with medical cotton balls, which poses a risk of infectious diseases being transmitted through the blood.

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

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

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

[0067] The driving end of the driver 120 extends into the negative pressure connecting rod 140; the ejection rod 150 is arranged inside the negative pressure connecting rod 140, and an ejection elastic member 141 is connected between the head end of the ejection rod 150 and the driving end of the driver 120; that is, the ejection elastic member 141 is located inside the negative pressure connecting rod 140.

[0068] The tank body 200 includes a tank body 210, a support rod 220, an impact moving rod 230 and a lancet 240; the support rod 220 is fixedly connected to the tank body 210, and the support rod 220 passes through the inner wall and the outer wall of the tank body 210; a part 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, and the lancet 240 is located inside the tank body 210.

[0069] The support rod 220 is detachably and hermetically connected to the negative pressure connecting rod 140 , and the tail end of the ejection rod 150 can abut against and impact the moving rod 230 .

[0070] The ejection elastic member 141 is configured to be compressed and produce elastic deformation when the driving end of the driver 120 moves. After the ejection elastic member 141 is compressed to a 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.

[0071] A limiter 142 is provided inside the negative pressure connecting rod 140 to limit the moving distance of the ejection rod 150, thereby limiting the moving distance of the impact moving rod 230 and the lancet 240. It should be noted that when the ejection elastic member 141 drives the ejection rod 150 to move inside the negative pressure connecting rod 140, the limiter 142 limits the moving distance of the ejection rod 150, thereby ensuring that the impact moving rod 230 moves a preset distance, thereby ensuring that the lancet 240 moves a preset distance, and ensuring that the force and depth of the lancet 240 are basically consistent during each automatic ejection; for example, the driving end of the driver 120 moves downward to press the ejection elastic member 141, and the ejection elastic member 141 is compressed to a preset elastic deformation size, driving the ejection rod 150 to eject downward to the limiter 142, thereby driving the impact moving rod 230 to move downward a preset distance, thereby driving the lancet 240 to move downward a preset distance.

[0072] Optionally, the ejection elastic member 141 is a spring or other elastic member.

[0073] Optionally, the driver 120 is a diaphragm pump or other direct current pumps.

[0074] Optionally, the stopper 142 and the ejection rod 150 are interference fit, and the ejection rod 150 can move along the stopper 142. The stopper 142 and the ejection rod 150 are interference fit, so that there is a certain static friction force between the stopper 142 and the ejection rod 150. When the actual elastic deformation size of the ejection elastic member 141 being compressed is smaller than the preset elastic deformation size, the static friction force acts on the ejection rod 150 and can offset at least part of the force from the ejection elastic member 141 acting on the ejection rod 150, so as to keep the ejection rod 150 from moving and store energy for the ejection of the ejection rod 150.

[0075] The specific operation scheme of the automatic bloodletting and cupping device of this embodiment is, for example, that the cup body 200 is mounted on the body 100, and the operator holds the body 100 and places the cup body 200 on the position to be treated on the human skin, and in particular, the position of the lancet 240 corresponds to the position to be treated. The operator holds the body 100, for example, the operator holds the body 100 by holding the housing 110.

[0076] In some embodiments, the negative pressure connecting rod 140 is disposed inside the housing 110. Figure 1 and Figure 3 Alternatively, the negative pressure connecting rod 140 is disposed outside the housing 110, such as Figure 4 Those skilled in the art can also Figure 4 The negative pressure connecting rod 140 shown is provided with the housing 110 at its periphery. The specific connection position relationship between the negative pressure connecting rod 140 and the housing 110 can be determined according to the requirements.

[0077] The automatic bloodletting and cupping device in this embodiment includes a body 100 and a tank body 200. The body 100 includes a shell 110, a driver 120, a negative pressure connecting rod 140 and an ejection rod 150. The tank body 200 includes a tank body 210, a support rod 220, an impact moving rod 230 and a lancet 240. The driving end of the driver 120 moves to drive the ejection elastic member 141 to be compressed and produce elastic deformation. After the ejection elastic member 141 is compressed to a preset elastic deformation size, the ejection rod 150 can be driven to 150 moves 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, and the force of the lancet 240 during each automatic ejection is basically the same; through the limiter 142 set inside the negative pressure connecting rod 140, the moving distance of the ejection rod 150 is limited, and then the moving distance of the impact moving rod 230 and the lancet 240 is limited, that is, the acupuncture depth of the lancet 240 during each automatic ejection is basically the same. The automatic bloodletting and cupping bloodletting device realizes the automatic ejection of the lancet 240, and its stability performance is better. The acupuncture force and acupuncture depth of the lancet 240 are basically constant during each ejection, which effectively solves the problem of uncontrollable acupuncture force and acupuncture depth caused by the differences in operations of different operators.

[0078] At present, cupping therapy often uses manual ignition to form negative pressure in the cup, which is complicated to operate and has poor safety performance. The negative pressure formed by manual ignition in the cup is uncontrollable, and often causes skin damage and blisters due to excessive negative pressure in the cup. There is also the problem of scalding the patient during ignition and even causing fire. In order to solve the above problems, see Figure 1-Figure 4 As shown, in an optional solution of this embodiment, the body 100 also includes a negative pressure vacuum pump 130; the negative pressure vacuum pump 130 is connected to the inside of the negative pressure connecting rod 140 and is configured to extract gas from the inside of 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 the ejection through holes 152 is one or more, and the multiple ejection through holes 152 can be arranged along the axial direction or circumferential direction of the ejection rod 150.

[0080] The impact moving rod 230 has a tank air passage connected to the inner cavity of the tank body 210. For example, the impact moving rod 230 is provided with a through hole at a position close to the bloodletting needle 240, or the tail end of the impact moving rod 230 is provided with a through hole, and the through hole connects the tank air passage and the inner cavity of the tank body 210; wherein, the tail end of the impact moving rod 230 is connected to the bloodletting needle 240.

[0081] Optionally, the front end of the impact moving rod 230 has a floating valve 231 for blocking the tank air passage. When the ejection rod 150 abuts against the impact moving rod 230, the floating valve 231 is located in the ejection chamber 151; the floating valve 231 is configured to be able to move in a direction away from the tank body 210 under the negative pressure of the negative pressure vacuum pump 130 to open the tank air passage; for example, when the negative pressure vacuum pump 130 extracts the gas inside the negative pressure connecting rod 140, the negative pressure is first extracted. The gas between the connecting rod 140 and the outer wall of the ejection rod 150 is then extracted from the ejection chamber 151 inside the ejection rod 150 through the ejection through hole 152, so that the ejection chamber 151 is in a negative pressure state. As the negative pressure vacuum pump 130 continues to extract, the floating valve 231 moves in a direction away from the tank body 210 under the drive of the negative pressure and opens the tank airway to extract the gas in the inner cavity of the tank body 210, so that the inner cavity of the tank body 210 is in a negative pressure state. Optionally, after the tank body 210 leaves the machine body 100, since the inner cavity of the tank body 210 is in a negative pressure state, the negative pressure suction force of the inner cavity of the tank body 210 drives the floating valve 231 to move in a direction close to the tank body 210 to close the tank airway.

[0082] Optionally, in some embodiments, the floating valve 231 opens the tank airway under the drive of negative pressure to make the inner cavity of the tank body 210 in a negative pressure state, and then the driving end of the driver 120 moves and drives the ejection elastic member 141 to produce elastic deformation; when the actual elastic deformation size of the compressed ejection elastic member 141 reaches the preset elastic deformation size, the ejection elastic member 141 drives the ejection rod 150 to eject and 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. After the ejection rod 150 ejects and moves, the driving end of the driver 120 can quickly retreat to the original position, canceling the force on the ejection elastic member 141.

[0083] like Figure 2 As shown, optionally, the floating valve 231 includes a spherical portion located at the top thereof, the spherical portion is located outside the impact moving rod 230, and the spherical portion can be sealed and connected with the impact moving rod 230 to close the tank airway. Optionally, the inner wall of the head end of the impact moving rod 230 is provided with a vent structure 235, for example, the vent structure 235 is a mesh, and the bottom end of the floating valve 231 can abut against part of the vent structure 235, at which time the tank airway is in an open state; through the vent structure 235, the communication of the airway can be guaranteed, 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 extracts the gas inside the negative pressure connecting rod 140 through the negative pressure vacuum pump 130, and then extracts the gas in the inner cavity of the cup body 210, so that the inner cavity of the cup body 210 is in a negative pressure state, which can effectively avoid the problems of complicated operation process and poor safety caused by manual ignition to form negative pressure in the cup.

[0085] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, the tank body 200 further includes an impact elastic member 250 disposed inside the support rod 220; the impact elastic member 250 is connected to the impact moving rod 230, and the impact elastic member 250 has an elastic deformation that drives the impact moving rod 230 to extend out of the support rod 220; through the impact elastic member 250, the impact moving rod 230 can be driven to reset, and then the lancet 240 can be driven to reset. For example, the ejection rod 150 ejects and moves inside the negative pressure connecting rod 140 to drive the impact moving rod 230 to move, and then drive the lancet 240 to move, and at the same time, the impact elastic member 250 also generates 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 are reset under the elastic action of the impact elastic member 250.
