Description

TECHNICAL FIELD

[0001] The utility model relates to syringe technical field, concretely relates to a vacuum blood test filter gas oxygen needle. BACKGROUND

[0002] Acupuncture has a successful experience of thousands of years in Chinese history, and is particularly effective for treating chronic diseases.

[0003] The utility model patent with the publication number CN201082280Y discloses a vacuum blood test filter gas qigong needle. The patent document includes the processes of vacuum blood test, filter gas, gas operation and medium therapy.

[0004] The vacuum blood test is to verify whether the acupuncture needle has been inserted into a blood vessel after being inserted into an acupoint. When the needle handle is pulled, the needle tube is in a negative pressure, i.e. a vacuum state. If blood is sucked into the needle tube, it proves that the needle tip has been inserted into a blood vessel, and the needle must be reinserted to prevent the true qi from being injected into the blood vessel, causing gas embolism and endangering life. If the needle tip is not in a blood vessel but in an acupoint, there will be no bleeding, which is the vacuum blood test.

[0005] The filter gas has a filter gas hole groove on the needle tube. When the needle handle is pulled, if no blood enters the needle head in the vacuum state of the needle tube, it indicates that the needle head is not in a blood vessel. At this time, the filter gas hole groove is opened, and air, i.e. natural negative oxygen ions, enter the needle tube, so that the negative pressure in the needle tube changes to positive pressure, and the vacuum state changes to a state rich in negative oxygen ions, which is called vacuum filter gas.

[0006] The gas operation is that when the needle tip is inserted into an acupoint but not in a blood vessel, the rubber piston of the needle handle is pushed to the bottom of the needle tube, so that the filtered natural negative oxygen ions in the tube enter the acupoint to change the situation of qi stagnation and blood stasis in the acupoint, so as to achieve the purpose of treating diseases by combining negative oxygen ions with acupuncture.

[0007] The medium therapy is that the medium used is first sucked into the needle tube, and then the acupuncture needle is inserted into the required acupoint, and then the needle handle is pulled to see if blood is sucked into the needle tube. If so, the depth of the needle head should be changed to prevent the drug liquid from entering the blood vessel and affecting the therapeutic effect. If not, the medium can be injected into the acupoint to achieve the purpose of treating diseases.

[0008] In the patent document, air can enter the needle tube. However, the current air contains a lot of dust or carries bacteria, and it does not have a filtering function, resulting in impure air entering the body and poor treatment effect. At the same time, in the medium therapy in the patent document, the medium is first introduced into the needle tube, and then the vacuum blood test is performed. The vacuum blood test needs to drive the medium to move first, and the negative pressure generated by pulling the needle handle is low, so the vacuum blood test process may not be successful.

[0027] In this embodiment, when vacuum blood test is performed, the needle is connected with the injection head 2, and the needle is inserted into the acupoint. If blood is sucked into the needle tube, it proves that the needle is inserted into the blood vessel. If no blood enters the needle tube, it proves that the needle does not enter the blood vessel. Thus, the vacuum blood test is realized.

[0028] When air filtering is performed, the first closing cover 9 is removed, so that air enters the cavity through the branch pipe 7. At this time, the air is filtered by the air filter, and the entering air is cleaner. When air is operated, the first closing cover 9 is installed, the piston rod 4 is pushed to move downward to drive the piston 3 to move downward, so that the negative oxygen ion in the air enters the acupoint, changes the condition of qi stagnation and blood stasis in the acupoint, and uses the negative oxygen ion combined with acupuncture to achieve the purpose of treating diseases.

[0029] When medium therapy is performed, first, the first closing cover 9 and the second closing cover 12 are in the installed state, and vacuum blood test is performed. After the vacuum blood test is completed, the second closing cover 12 is removed, and then the puncture needle 10 passes through the rubber bottle cap of the medium medicine bottle, and then the piston rod 4 is pulled to move upward so that the medium in the medium medicine bottle enters the cavity.
