Nasal hemostasis device

Abstract

The invention discloses a nasal hemostasis device. The device includes a catheter, a balloon is connected to the tail end of the catheter, and the outer periphery of the catheter is covered with an expansion hemostatic material. When the device is used, the balloon and the catheter are inserted into a nasal cavity, the balloon is inserted into the position of posterior nostrils, and a fluid / gas isintroduced into the balloon through the catheter to inflate the balloon for hemostasis of the posterior nostrils; at the same time, the expansion hemostatic material is located in the nasal cavity, and if an anterior nasal cavity bleeds, the expansion hemostatic material can suck blood and swell for hemostasis of the anterior nasal cavity; and after hemostasis is completed, the fluid / gas is drawnfrom the balloon through the catheter to contract the balloon, the volume of the balloon is reduced when the fluid / gas is drawn out, so that the device does not cause secondary damage to a wound surface.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a nasal cavity hemostasis device. Background technique [0002] Epistaxis is a common disease in outpatient and emergency departments. Local factors such as trauma, nasal cavity, nasal sinuses, and nasopharynx tumors, nasal foreign bodies, barotraumatic sinusitis, and acute febrile infectious diseases, heart and circulatory system diseases, hemorrhagic diseases, liver and kidney diseases, and rheumatic fever. factor. Regardless of the etiology, it should be treated according to the symptoms, stop bleeding first, and effectively control nasal bleeding in time to avoid serious consequences caused by heavy bleeding. [0003] Due to the particularity of the anatomy of the nasal cavity, the irregular structure of the nasal cavity and the large differences in the size of the individual nasal cavity and sinus, it is required that the packing material after the na...

Problems solved by technology

[0003] Due to the particularity of the anatomy of the nasal cavity, the irregular structure of the nasal cavity and the large differences in the size of the individual nasal cavity and sinus, it is required that the packing material after the nasal cavity and sinus surgery should be plastic; The pressure required for postoperative packing is also different, and local pressure for hemostasis, if the pressure is too high, will seriously affect the local blood supply, making local metabolism slow down, which is not conducive to postoperative wound healing. no hemostasis

[0004] None of the existing hemostatic materials and hemostatic devices can effectively control the volume and pressure of the packing material, and at the same time, it is easy to cause secondary damage to the wound when the related products are taken out after the operation, and the existing products cannot effectively control the posterior nostril bleeding
