In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the parts having the same structure or function is schematically shown, or only one of them is marked.
[0032] Please refer to Figures 1 to 7 to understand the present application.
[0033] Please refer to Figures 1 to 3 , the rear nasal cavity hemostatic kit comprises a hemostatic plug 201 and a suction pipe 101.
[0034] The suction tube 101 includes a connecting end 109 that can be connected to a negative pressure device and an inserting end 110 for inserting into the nasal cavity. The suction tube 101 is provided with a hook part that can hook the connecting part. The suction tube 101 can have a certain rigidity so that it can maintain a certain forward direction when passing through the nasal cavity.
[0035] The hemostatic plug 201 is connected to a traction rope 202. The hemostatic plug 201 can be made of materials such as cotton yarn or hemostatic sponge. The traction rope 202 has a connecting part. The connecting part can be the rope between the two ends of the traction rope 202 when the two ends of the traction rope 202 are connected to the hemostatic plug 201, or it can be a loop structure formed by the traction rope 202 itself, so that the hook part can hook the connecting part. It will not be described in detail here.
[0036] The suction tube 101 has multiple suction holes 102 on its side wall. When the connecting end 109 is connected to a negative pressure device, the suction holes 102 can suction blood from the nasal cavity to prevent blood from flowing into the trachea. On the other hand, it makes it convenient for medical staff to observe the condition of the patient's nasal cavity through an endoscope.
[0037] In one embodiment of this application, the hook portion includes a first hook portion 104, which is disposed at the insertion end 110. See [link to relevant documentation]. Figure 1 The first hook portion 104 is a hook located at the insertion end 110. Alternatively, the first hook portion 104 can also be a spring hook. The first hook portion 104 can be integrally formed with the suction tube 101, or it can be a hook made of bent metal wire. The metal wire can enter and exit the suction tube 101 along its axial direction to achieve different uses. The first hook portion 104 can hook onto the traction rope 202. (See also...) Figure 4 During the operation by medical staff, the insertion end 110 of the suction tube 101 reaches the throat through the patient's nasal cavity, and then the insertion end 110 is taken out through the mouth. The first hook part 104 hooks the traction rope 202. Then, the medical staff pulls the suction tube 101, causing the insertion end 110 in the mouth to move towards the back of the nasal cavity, which drives the hemostatic plug 201 connected to the suction tube 101 to move from the mouth to the back of the nasal cavity. The hemostatic plug 201 can stop the bleeding at the bleeding point. During this process, the suction tube 101 can always be in a negative pressure state to draw blood to the outside and avoid affecting the operation of medical staff.
