Abstract
The utility model relates to the field of medical equipment, specifically be a nasal cavity hemostat, this nasal cavity hemostat is the rotary -table shape, suits with the nasal cavity shape, constitute by core layer and auxiliary layer, auxiliary layer parcel in the core layer, the auxiliary layer evenly be provided with a plurality of holes, its simple structure, convenient to use stanchs rapidly and is effectual to can promote wound healing, and the not adhesion surface of a wound.
Description
Technical field
this utility model relates to medical instruments field, is specially a kind of nosal hemostat.
Background technology
Epistaxis, deviation of nasal septum, chronic nose-nasal sinuses meat, nasal polyp Shi Bi section commonly encountered diseases.No matter and be that former epistaxis or the process of surgery of nasal cavity posterula all need to carry out nasal packing in most cases and prevent hemorrhage, now usually adopt cotton balls, expandable sponges carry out imbibition, hemostasis, limited protection wound.But because compressing dynamics is inadequate, not good to small arterial hemorrhage haemostatic effect, when extracting and wound adhesion friction cause pain, make patient be difficult to stand, also easily cause wound secondary insult.Alginate material is due to its avirulence, without anaphylaxis, local organization reaction is extremely light and be widely used in wound care, wherein Sorbsan is because of its quality softness, compliance well and be more easily attached at mucous membrane surface be used to nose cavity hemostatic filling, but its hemostatic capability effectively and after contacting water liquefaction can lose its toughness and tension force, need to take out in 24 hours, if filling time comparatively long material decomposed and cause taking out easily, calcium alginate fibre also has a shortcoming to be as nose cavity hemostatic wadding, and medical personnel needed to fold or twist into nasal cavity shape and could clog before filling, increase the workload of medical personnel like this.
Utility model content
The purpose of this utility model only relies on compressing to stop blooding cause haemostatic effect not good to overcome existing nosal hemostat, not easy to operate, adhesion wound easily causes the defect of secondary insult, a kind of nosal hemostat is provided, its structure is simple, easy to use, stops blooding rapid and effective, and can wound healing be promoted, and adhesion wound surface.
The technical solution of the utility model is as follows: a kind of nosal hemostat, in Rotary-table shape, adapts with nasal cavity shape, is made up of core layer and auxiliary layer, and on core layers, described auxiliary layer is evenly provided with multiple hole to described auxiliary layer parcel.
Preferably, the diameter in described hole is 2mm.
Preferably, described auxiliary layer is anti-sticking medical film.
Preferably, described anti-sticking medical film is PE medical films or PLLA medical films.
Preferably, described core layer is alginate hemostatic sponge layer, in loose porous sponge structure.
Preferably, described alginate hemostatic sponge layer is prepared from by alginic acid zinc calcium salt.
Preferably, described core layer is rolled by the uniform alginate sthptic sponge of thickness and is formed, and therein in be formed centrally the passage of cone shape.
This utility model has the following advantages:
Nosal hemostat of the present utility model is filled in hemorrhage nasal cavity, Zinc alginate calcium salt sponge in alginic acid haemostat absorbs sepage and blood expands, make haemostat fully clog nasal cavity tract, with the sodium ion generation ion-exchange reactions in transudate after Zinc alginate calcium salt soaks, discharge Ca
2+and Zn
2+and then reach the object of quick-acting haemostatic powder.Meanwhile, after alginate sponges expands, good hemostasis by compression effect is had.Therefore, this nosal hemostat not only can physical property hemostasis can also biological hemostatic thus reach double-hemostasis function effect.
The shape Rotary-table shape of nosal hemostat of the present utility model, adapts with the nasal cavity shape of people, nosal hemostat and nasal cavity inwall can be made to fit tightly, nosal hemostat also can be made firmly to be fixed on nasal cavity.
When taking out haemostat, the skin due to haemostat is provided with anti-sticking medical film, and anti-sticking medical film is provided with multiple hole, and core layer both can have been made to absorb wound exudate, can prevent wound adhesion again and effectively avoid the risk of wound secondary damage.
Core layer is rolled by the uniform alginate sthptic sponge of thickness and is formed, and therein in be formed centrally the passage of cone shape, its structure is simple, produce simple and easy, production cost can be effectively reduced, under the combined effect in the hole of the passage that core layer is formed and auxiliary layer, make this utility model can keep the unobstructed of nose breathing while hemostasis.
Therefore, this utility model overcomes existing nosal hemostat and only relies on hemostasis by compression to cause haemostatic effect not good, not easy to operate, easily cause the defect of secondary insult, a kind of nosal hemostat provided, its structure is simple, easy to use, stop blooding rapid and effective, and can wound healing be promoted, and adhesion wound surface.
