New description: [New technical field] This creation is related to medical examination of the cavity or tube of the human body by visual or photographic examination, especially a closed structure in which the catheter needle prevents air from escaping. ♦ 【Prior Art】 * In the past, before the operation of the abdominal cavity of the patient, it is necessary to know the condition of the patient's anterior abdominal cavity. Only the external X-ray can be used to obtain a blurred image, otherwise it can only be obtained. The patient's abdomen can be directly cut open to understand the patient's symptoms and current conditions. However, only by X-ray, there may be unclear and unclear images, which may cause misdiagnosis. If the patient is opened, the patient's abdomen will be cut open. There is a medical risk arising from the wounding of the knife, so how to simply and clearly observe the condition of the patient's abdominal cavity becomes a development direction. Thus, a catheter needle as shown in Figures 1 and 2 has been developed, which comprises a catheter A, a check sleeve B, a retaining ring C, an end cap D and a puncture knife E, the catheter A having a pass The hole A1 and the air hole A2 are connected to the air hole A2. The check sleeve B is made of a flexible material, and the check sleeve B, the fixing ring C and the end cover D are sequentially disposed on the duct A. On one end A3, the puncture knife E is sequentially inserted through the end cap D, the fixing ring C and the check sleeve B, and the M338639 is inserted in the through hole A1 of the catheter A; when the cardiac needle is used, as shown in Fig. 3 , the other a4 of the catheter a is pressed on the abdomen of the human body F ^ F ^ Dan Xiaosi 40, the puncture knife is in the (5) tube A 'the puncture knife E passes through the through hole of the catheter A After M 'as shown in Figure 5' will the abdomen of the human body? The opening-hole ρι, and then shown in Fig. 6, is attached to the end M of the catheter A and the body _ portion by the tape 0, so that the catheter A can be fixed to the abdomen F, and is withdrawn from the catheter A and The tooth lance E' sub is externally connected to the air source A2 of the duct A, and the air is passed through the D-hole JF1 and filled into the abdomen F of the human body to expand the abdomen F, and the positive and negative sleeve B can seal the catheter A. A3, so that the air does not leak outward from the end A3 of the catheter A. When the tool H is passed through the through hole A1 of the catheter through the abdomen F as shown in Fig. 7, the air is filled in the abdominal cavity. When the abdomen F is inflated, the condition in the abdomen F can be clearly seen; it can be seen that the catheter needle can clearly and in detail observe the condition and the condition in the abdominal cavity of the patient as long as a small hole is opened in the patient's abdomen, in judging the condition and the operation. It is easier, however, when the tool H passes through the through hole ai % of the catheter A, the stomach expands the δ 止 逆 逆 β β as shown in Fig. 8 to create a gap between the tool η and the anti-reverse sleeve. Α5, the air will leak out from the gap Α5, so the external sputum source must constantly replenish air into the abdomen F In the case where the tool is inserted into the through hole Α1, it can be kept closed, which is more convenient and easy to work. M338639 The name of the second name II developed the patent application number of the Republic of China. The 91220m proprietary technology is 'added to the leak-proof ring when it is set. When the tool passes through the leak-proof ring & the ride will be spread by the tool and tightly matched with the tool. In this way, the side leakage preventing ring is sealed to prevent the air from leaking outward; however, this technique strictly speaking, the sealing effect is only provided by the leakage preventing ring, and when the tool moves left and right to pull the leakage preventing ring, the The anti-leakage ring may be in a state of being turned off and close, so that U is still sparse, so how to provide better density, and then the current primary research and development goals. [New content] The purpose of the present invention is to provide a sealing structure for preventing the air from escaping through the catheter needle, which is difficult to provide a better sealing effect by the split type. The second object of the present invention is to provide a closure structure for preventing the air from escaping by a catheter needle, which is configured by an elastic ring to allow the closure structure to be automatically reset after being engaged with the tool.
