Embodiment Construction

[0018] Below, the applicant further describes the technical solution of the present invention in detail in conjunction with specific examples, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the scope of protection claimed by the present invention.

[0019] Such as figure 1 As shown, the present invention provides a nasal septum hemostasis drainage device, which includes a suction unit and a high negative pressure unit connected to each other. The suction unit is mainly used for implanting in the septum operation cavity, draining the congestion from the septum operation cavity and forming it. In the negative pressure state, the high negative pressure unit is used to provide negative pressure, and the suction unit is provided with a one-way valve 6 to prevent air and blood from entering the nasal septum cavity in reverse. Such as figure 2 As shown, the suction unit includes a negat...

Abstract

The invention relates to the field of medical equipment, in particular to a nasal septum hemostatic drainage device. The nasal septum hemostatic drainage device comprises an attraction unit and a highnegative pressure unit which are connected with each other; the attraction unit is provided with a one-way valve used for preventing air and blood from reversely entering the nasal septum cavity; thehigh negative pressure unit comprises a high negative pressure cylinder shell, a rubber coupling inner core and a compression spring, the rubber coupling inner core is coupled with the high negativepressure cylinder shell, and the rubber coupling inner core freely slides in the high negative pressure cylinder shell to form a closed cavity; and the compression spring is arranged between the rubber coupling inner core and the tail end of the high negative pressure cylinder shell. The nasal septum hemostatic drainage device not only can perform negative pressure drainage hemostasis by compression, prevent the hematoma formation, but also can promote wound healing, can also ensure the normal nasal ventilation, and solves the problem that nasal packing needs to be used for hemostasis after the nasal septum surgery in the past.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a nasal septum hemostasis drainage device. Background technique [0002] Nasal septum deviation is a common and frequently-occurring disease, and it is mainly treated with nasal septum correction surgery. After nasal septum surgery, it is usually necessary to use the method of stuffing the nasal cavity to stop bleeding. The stuffing usually adopts alumite gauze, high-expansion hemostatic sponge, air bag, etc. The main disadvantage of the nasal packing hemostasis method is that it causes local distending pain in the nasal cavity, headache, nasal obstruction, ear fullness, etc. The above-mentioned discomfort caused by nasal packing hemostasis will cause the patient to suffer unbearably. Moreover, sometimes if the packing is not in place, bleeding may occur on the wound surface of the nasal septum, forming a hematoma in the nasal septum. After secondary infection, abscess of the nasa...
