A negative pressure device and method using the negative pressure device for prevention, treatment and recovery of disease, particularly a hollow needle device and method of inserting a needle with channel into the connective tissue under the skin of a patient, and sleeve-coupling a rubber tube, one end of the rubber tube is sleeve-coupled with the needle with channel, and the other end of the rubber tube is sleeve-coupled with a healthcare machine for dredging meridians and collaterals, which stimulates the acupoints via appropriate negative pressure. Due to the use of negative pressure, the six exogenous pathogens, i.e. wind, cold, summer heat, humidity, dryness and fire accumulated in the body can be extracted, the obstructed meridians and collaterals can be dredged, the end of open all the channels and to cure all the diseases can be reached. This is a completely new acupuncture method, it breaks people&#39;s stereotype about traditional acupuncture as being highly dependent on personal skills and expertise. The emergence of the hollow needle is a breakthrough of the acupuncture therapy. The present invention relates to a method of operating the hollow needle device and methods using the hollow needle device to dredge meridians and collaterals to achieve prevention, treatment and recovery of diseases. 
     BACKGROUND OF THE INVENTION 
       Jing Yue Quan Shu  points out “all internal diseases have external symptoms”, it means lesion of internal organs can be reflected as certain symptoms or positive reaction points at parts or respective body surfaces where the meridians and collaterals pass. Therefore, acupuncture of certain parts, acupoints or positive reaction regions can dredge the meridians and collaterals, adjust deficiency and excess of the viscera, adjust the qi and blood, and balance ying and yang. Research of modern acupuncture and meridian biophysics indicates, having acupuncturing any acupoints, the stimulation tends to reach the organs associated with the acupoints along the layout of the meridians and collaterals even without subjective feeling, resulting healthcare and/or treatment effects. 
     However, acupuncture is a sophisticated science. A significant portion of knowledge is know-how expertise. No single acupuncture therapy is universal. To achieve good healthcare and treatment effects, every acupuncturist has to master a variety of acupuncture therapies, and to apply a relatively appropriate one for different sicknesses. Besides, despite some acupuncture therapy may be effective upon the first use, it becomes less effective with subsequent frequent use within a short period. In addition, traditional acupuncture therapy may result needling sensation of soreness, numbness, swell and pain, and has the problem of long duration of needle retention. 
     In this regard, a quick-acting, safe, low or non-pain acupuncture therapy without damage to healthy tissues, causing scars or sequelae is desirable.

The exhaust pipe connector  123  establishes physical and fluid connection with the exhaust pipe  3 . The exhaust pipe  3  preferably is made of soft plastic material, such that the exhaust pipe  3  can wrap and pinch the exhaust pipe connector  123  of the hollow needle adaptor  12 . The flange  122  of the hollow needle adaptor  12  limits the extent of the wrapping of the exhaust pipe  3 . The exhaust pipe  3  can have a suitable length to facilitate acupuncturing operation of doctor. In one embodiment, the end of the exhaust pipe  3  that connects the exhaust pipe connector  123  of the hollow needle adaptor  12  has a diameter-enlarged portion  31 . 
     The host machine  2  of the hollow needle device of the present invention comprises a control module M. In one embodiment, the control module M comprises a time control module M 1 , a negative pressure control module M 2 , a negative pressure monitor and display module M 3 , a pump control module M 4  etc. The time control module M 1  is used to set the time of operation of the hollow needle device, i.e. the time of maintaining negative pressure. The negative pressure control module M 2  is used to set the amount of negative pressure applied in the through hole of the tip  111 . The negative pressure monitor and display module M 3  is used to measure and display negative pressure. The pump control module M 4  is used to operate a vacuum pump M 7  to achieve the set negative pressure. In another embodiment, the host machine  2  can be integrated inside or connected outside the vacuum pump M 7 . The vacuum pump M 7 , for instance, is an aluminum micro air compressor. The vacuum pump can have a pre-filtering device M 6  so as to prevent air or other pollutant from the hollow needle assembly  1  from contaminating or damaging the vacuum pump M 7 . The host machine  2  further comprises an exhaust pipe interface M 5  to connect the exhaust pipe  3 , and an electrical interface M 8  for power input. 
     Method 
     Below is an introduction of a method using the hollow needle device of the present invention to dredge meridians and collaterals. 
     After completing sterilization and connection of related devices S 1 , an acupuncturist first inserts a hollow needle  11  into the affected part of a patient, particularly to the subcutaneous connective tissue S 2 . After the insertion, the acupuncturist switches on the host machine  2  to set the negative pressure in the through hole of the hollow needle  11 , and operates the vacuum pump M 7  to achieve the set negative pressure S 3 . After maintaining the negative pressure for a predetermined period of time S 4 , the hollow needle is withdrawn S 5 . 
     It is important to keep negative pressure in the through hole of the hollow needle  11 . By no means can any air or drug enter the acupoints of human body. 
     Besides, there are a number of considerations in implementing the aforementioned method: 
     (1) Posture of body. During the acupuncture and application of negative pressure, a suitable posture of body should be chosen for the patient. The posture of body mainly comprises clinostatism and leaning posture, however other suitable postures are also possible. 
     (2) Selection of hollow needle. Suitable hollow needle  11  should be chosen from the hollow needle assembly  1  consisting of hollow needles  11  of different sizes for treatment. The selection of size of hollow needle is dependent on the parts to be treated and the seriousness of the sickness. In one embodiment, hollow needle  11  having a tip  111  diameter of 0.3-0.45 mm is selected for face, hollow needle  11  having a tip  111  diameter of 0.5-0.7 mm is selected for limbs. 
     (3) Angle of needle insertion. Horizontal insertion, oblique insertion or vertical insertion can be chosen for different parts. For horizontal insertion the hollow needle  11  enters the skin at a relative angle of around 15 degrees, For oblique insertion the hollow needle  11  enters the skin at a relative angle of around 45 degrees, For vertical insertion the hollow needle  11  enters the skin at a relative angle of around 90 degrees. 
     (4) Acupuncturing locations. Upon insertion, the tip  111  should aim at physical disorder parts, acupoints are selected depending on seriousness of disease. For pain diseases, Tendon membrane trigger points (MTrP) or positive points can be selected as acupuncturing locations. The physical disorder parts or positive points can be identified from: (i) points where it feels sore when pressed, (ii) points where it feels abnormal band or spasm when pressed, (iii) nodular or granular nodules, (iv) points where the patients feels comfortable or symptom relieved when pressed. 
     Upon insertion, it should avoid black spots, nodules, damages, depressions, protuberances and superficial veins. Since negative pressure is to be applied, care must be taken not to pierce veins. Having connected the host machine  2  and before applying the negative pressure, the doctor must observe whether there is any bleeding. If there is any bleeding, the process must be paused, the needle must be withdrawn and reinserted. 
     In addition, it is preferable not to perform acupuncture at the lower abdomen to woman pregnant for less than three months. For woman pregnant for more than three months, it is preferable not to perform acupuncture at the lower abdomen, the abdomen and the lumbosacral portion. It is also preferable not to perform acupuncture to patients with spontaneous hemorrhagic disease or patients who cannot stop bleeding after injury. 
     During one treatment, multiple acupoints can be chosen for multiple acupunctures. 
     (5) Speed of needle insertion. The speed of insertion should generally be fast. Because the dermis layer has a large amount of nerve endings, the faster the speed of insertion, the less pain that can be felt. 
     (6) Extent of negative pressure. Different extent of negative pressure is set for different affected regions. In one embodiment, the doctor may choose negative pressure of 20-40 cmHg (0.263-0.526 atm) for head and face; negative pressure of 40 cmHg (0.526 atm) for neck; negative pressure of 70 cmHg (0.921 atm) for waist; negative pressure of 40-50 cmHg (0.526-0.658 atm) for fingers; negative pressure of 50-70 cmHg (0.658-0.921 atm) for upper limbs; negative pressure of 60-76 cmHg (0.789-1 atm) for lower limbs. The extent of negative pressure is selected such that the acupoints, airways and/or meridians and collaterals at the affected regions that are obstructed can be dredged, rigid tendons can become flexible and elastic, and adhered muscle can become soft. It overcomes the poor curative issue of traditional acupuncture therapy; the symptoms of lingering diseases can be relieved immediately. 
     (7) Timing of needle insertion. It is not appropriate to perform needle insertion when the patient is hungry, tired or tense. 
     (8) Duration of needle retention. For each acupoint and each acupuncture, the negative pressure in the hollow needle  11  is maintained for no more than 10 minutes, preferably for no more than 5 minutes. In a more preferable embodiment, the negative pressure is maintained for 2-5 minutes. 
     (9) The method of the present invention must be carried out by registered medical practitioner who has been trained professionally, and with the healthcare machine for dredging meridians and collaterals and the hollow needle of the present invention. 
     Working Principles 
     The device and method of the present invention can create continuous negative pressure at the subcutaneous connective tissue adjacent to the tip of the hollow needle, thereby lower the pressure at the region of lesion, relieve congestion, extravasated blood and swelling, and facilitate excretion of algogenic substance. In addition, under continuous negative pressure, tissues like the skin, vein and tendon can be more relaxed, the flow of qi and blood is smoother, metabolism is enhanced and the symptoms of patients can be relived more quickly. 
     The hollow needle treatment of the present invention is a guidance and regulation of qi and blood. The acupuncture mechanically stimulates the biological effect of the connective tissue, thereby regulate the function (activity of histocyte) and life (repair and regeneration of histocyte) of human body. Subcutaneous loose connective tissue has a liquid crystal state. The needle by means of negative pressure can change the spatial configuration of the liquid crystal state of the loose connective tissue. Due to piezoelectric effect, it releases bioelectricity; when the bioelectricity reaches pathological tissues, it generates converse piezoelectric effect, which changes the ion channels of cells, regulates the disease-resistance mechanism, and dissolves indisposition quickly. 
     The working principles of the present invention can be generalized as the following aspects: 
     (1) Dredging Meridians and Collaterals 
     The meridians and collaterals are channels for qi, blood and body fluid to flow, are conductive system connecting internal organs, body surface and all the body parts. The meridians and collaterals comprise mainly twelve meridians distributed all around the body, they run qi and blood, moisten and nourish internal organs, skins, muscles, tendons and bones, so that various parts can function properly and keep relative balance. Hence the saying “meridians and collaterals can determine life and death, cure all diseases, adjust deficiency and excess, they can&#39;t be obstructed”. 
     The theory of Chinese medicine stipulates that pain is an important indication of obstruction of the meridians and collaterals, i.e. “obstruction causes the pain”. Therefore, to cure pain it must start with dredging the meridians and collaterals. The hollow needle of the present invention can dredge the meridians and collaterals, regulate qi and blood by means of negative pressure, thereby relieving various diseases resulting from qi stagnation, blood stasis and obstruction of meridians and collaterals for various reasons, especially swelling and pain of limbs and internal organs, numbness of limbs, flaccid and contracture of muscles and hypofunction as a result of obstruction of meridians and collaterals, qi stagnation and blood stasis. 
     (2) Facilitating Micro-circulation 
     Loose connective tissue is one of the most common and most influential factors in the human body. All systems of human body are connected with the connective tissue. Loose connective tissue has abundant cells, fibers, blood capillaries, lymphatic capillaries and tissue fluid rich in neurotransmitter (such as acetylcholine). 
     The hollow needle treatment of the present invention generally chooses region of lesion or MTrp points for needle insertion. It inserts the needle horizontally to subcutaneous shallow and loose connective tissue. By means of negative pressure, it can improve the internal environment of the lesion, particularly enhance regional blood and lymphatic circulation, so that tissues around the lesion can be relaxed, the fibrocytes can restore elasticity, the conduction pathway for neurotransmitter can become unimpeded to play a better role in respective tissues. After the hollow needle treatment, patients can feel rigid and spastic tissues become relieved and nodular nodes and abnormal bands become thin. They feel relaxed and pains relieved after the needle is withdrawn. 
     (3) Regional Depressurizing 
     The hollow needle treatment of the present invention can insert needle vertically into the pain sites (i.e. the ashi acupuncture point) and reduce local pressure of the lesion region by applying vacuum, it can relieve regional congestion, extravasated blood and swelling, and facilitate excretion of algogenic substance. 
     The hollow needle treatment of the present invention can also insert needle around the pain point (up, down, left, right), the insertion site should avoid vessel. By applying continuous negative pressure in the tissue, regional blood circulation can be enhanced, edema can be absorbed, inflammation can be eliminated, the pressured nerve can be relaxed and vessels can restore their functions. 
     (4) Relaxing 
     When the muscle tissue is in a tension state, the regional blood circulation can be impeded, causing tissue ischemia and hypoxia. The hollow needle treatment of the present invention can relax the spasm and tension of striated muscle and smooth muscle, can “treat pain with relax” and “kill pain resulting relax”. The hollow needle treatment of the present invention can directly excrete the pathogenic factors and excessive phlegm within the meridians and collaterals, can dredge the obstructed meridians and collaterals, and the pain will naturally disappear. Therefore, the hollow needle treatment of the present invention has the function of dissolving spasm and easing pain. 
     In addition, the hollow needle treatment of the present invention can cause hemangiectasis, facilitate local blood circulation, enhance metabolism, speed up excretion of waste and toxin within body, improve condition of nutrition of local tissues, provide more nutrition to cells, increase hemoperfusion to cells, relax the muscle and relieve fatigue. 
     (5) Eliminating Inflammation 
     The hollow needle treatment of the present invention can cure various bacterial inflammation and non-bacterial inflammation, the principle is activating the macrophage within the connective tissue, facilitate lymph circulation and blood circulation, increase the number of lymphocyte and white cells around the lesion, thereby increasing the regression of inflammation. 
     Based on the above working principles, the device and method of the present invention has wide clinical applications and can achieve good curative effect. The device and method of the present invention are mainly used to treat and/or relieve bounded pain, fullness and distention of limbs, paresthesia such as numbness and pain caused by diseases of internal organs. As unlimiting examples, the device and method of the present invention can be used to treat or relieve: 
     (i) Soft tissue pain, including but not limited to cervical spondylosis, scapulohumeral periarthritis, tennis elbow, tenosynovitis of the wrist, myofascitis of the back region, hernia of intervertebral discs, the third lumber vertebrae transverse process syndrome, sacroiliitis, gonarthritis, chronic ankle sprains and heel pain. 
     (ii) Neuro pain, including but not limited to pain following herpes zoster and prosopalgia. 
     (iii) Chronic visceral pain, including but not limited to stomacheache, cholecystitis, dysmenorrheal and annexitis. 
     (iv) Non-painful diseases, including but not limited to cervical vertigo, facial paralysis and chronic cough. 
     (v) General nursing, including but not limited to dredging the twelve medridians, regulating the internal organs, regulating the body and strengthening body immunity. 
     Effects 
     The inventor has chosen 14 long-term low back pain patients aged 31-60 for therapeutic test. These patients all have medical histories of longer than 6 months, they exhibit protrusion of the lumbar intervertebral disc observable by MRI due to degeneration of intervertebral disc, rupture of fibrous annulus of lumbar spine, herniation of the nucleus pulposus stimulating or pressurizing nerve root and cauda equina. Typical symptoms include low back pain, radiating ache in lower body and gastrocnemius tension due to pain in lower body. The inventor has quantitatively assessed the stiffness of gastrocnemius of each patient before and after treatment with the hollow needle device and method of the present invention. Axial and morphological information of gastrocnemius is obtained for each patient before and after treatment. From the morphological information stiffness of muscle at the left of the acupoint (AxL) and at the right of the acupoint (AxR) before and after treatment, and stiffness of muscle at the head side (SagH) and at the foot side (SagF) before and after treatment are obtained. The following table shows the measurement results.
