Description

A kind of sthptic sponge first-aid dressing

Technical field

This utility model belongs to medical first aid field, more specifically, relates to before one is applicable to institute or (showing) field of fighting Sthptic sponge first-aid dressing.

Background technology

According to statistics, in war, injures and deaths and the domestic wound death of up to 80% close to 50% is due to out of control hemorrhage, only Blood band is effectively to control hemorrhage first-aid equipment, but a lot of position of human body such as breast, abdomen, head, neck etc. cannot use hemostasis Band.Traditional hemostatic material (such as cotton yarn, binder) is for on-the-spot common wounds such as irregular wound, arteriorrhexis hemorrhagic traumas The haemostatic effect of wound is the most undesirable.Therefore, exploitation for before institute and war (showing) field first aid with quick, safe and effective newly Type tourniquet bandage becomes the important topic in medical first aid field.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one can be used for wounded's pre hospital care and wartime at ordinary times The sthptic sponge first-aid dressing of wounded's war (showing) field first aid.

The technical solution of the utility model is summarized as follows:

A kind of sthptic sponge first-aid dressing, including netted binder 2, the upper surface in netted binder left end end is disposed with First medical Waterproof glue line 7 and sthptic sponge 1；It is medical anti-that lower surface in netted binder left end end is disposed with second Gelatine layer 17 and waterproof plastic film 3, netted binder left end is fixing with lining cloth 4 to be connected；The upper surface of netted binder right-hand member sets Being equipped with intensified nylon hasp 5, the lower surface at the mid portion of netted binder is provided with velcro 6.

Advantage of the present utility model:

After being pressed on hemorrhage wound surface by sthptic sponge, hemorrhage wound surface can be realized quick-acting haemostatic powder, the lower surface interval of netted binder Arranging velcro, when can prevent being wound around wrapping, netted bandage roller inadvertently falls off；The intensified nylon hasp of the end of netted binder Hook face can be directly anchored to netted binder at the end of being wound around wrapping, wrapping is fixed a step and is completed, and saves emergency time.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further described.

A kind of sthptic sponge first-aid dressing (see Fig. 1, Fig. 2 and Fig. 3), including netted binder 2, at netted binder left end The upper surface of end is disposed with the first medical Waterproof glue line 7 and sthptic sponge 1；Following table in netted binder left end end Face is disposed with the second medical Waterproof glue line 17 and waterproof plastic film 3, and netted binder left end is fixing with lining cloth 4 to be connected； The upper surface of netted binder right-hand member is provided with intensified nylon hasp 5, and the lower surface at the mid portion of netted binder is provided with Buddhist nun Dragon hasp 6.

Sthptic sponge (mesoporous silica nano-particle-chitosan compound hemostatic sponge) is preferably made by following method:

1) in 100ml water, 300mg cetyl trimethylammonium bromide is added, with high pure nitrogen (99.99%) while stirring Purging 55min；

2) at 65 DEG C, under the stirring condition of 700rpm, to step 1) to be sequentially added into 9ml in the liquid that obtains the most pungent Alkane, 5g methyl methacrylate, 3ml tetraethyl orthosilicate and azo-bis-isobutyrate hydrochloride, described azo two 2,2-Dimethylaziridine salt The final concentration of 0.7mg/ml of hydrochlorate, regulates pH=9 with lysine, reacts 6h, then stands 16h, obtains milk-white coloured suspension；

3) by milk-white coloured suspension under the conditions of 12000rpm, centrifugal 20min, with dehydrated alcohol centrifuge washing 5 times；

4) in air atmosphere, with the heating rate of 2 DEG C/min, 600 DEG C of calcining 6h remove mesoporous template, it is thus achieved that white Aperture and the controlled mesoporous silicon rapid hemostasis powder of the equal single dispersing of particle diameter；After testing, particle diameter exists in 60 ± 5nm, the aperture on surface 15±2nm；

5) deacetylation 100%, the chitosan of mean molecule quantity 150,000 and step 4 that mass ratio is 1:1 are obtained stops Blood powder joins in the acetic acid aqueous solution that volumetric concentration is 0.5%, and the concentration making described chitosan is 0.5% (g/mL) stirring Mixing, pours in mould ,-50 DEG C of cryogenic quick freezing molding, recycles freeze dryer lyophilization 24h, is finally produced Product mesoporous silica nano-particle-chitosan compound hemostatic sponge.

Sthptic sponge can also select the sthptic sponge of prior art.

Chitosan is providing while hemostatic function, can be with the controlled mesoporous silicon quick-acting haemostatic powder of the equal single dispersing of constant aperture and particle diameter Powder particles, ensures the biological safety of its entirety.

A kind of sthptic sponge first-aid dressing of the present utility model, after being pressed on hemorrhage wound surface by sthptic sponge, aperture and particle diameter are equal The controlled mesoporous silicon quick-acting haemostatic powder powder particles of single dispersing can realize quick-acting haemostatic powder to hemorrhage wound surface, and chitosan is providing hemostasis merit While energy, granule can be fixed, ensure the biological safety of its entirety；Lining cloth person convenient to operate holds, it is ensured that hemostasis sea Silk floss is not by unclean hand contamination, and the interval, the back side of netted binder arranges bandage roller when velcro can prevent being wound around wrapping and surprisingly falls Fall；The intensified nylon of the end of netted binder can be directly anchored to netted binder at the end of snapping over winding wrapping, wrapping is fixing One step completes, and saves emergency time.

Embodiment described above is only to be described this utility model preferred implementation, not to of the present utility model Spirit and scope are defined, on the premise of without departing from this utility model design philosophy, and ordinary skill technology people in this area Member's various deformation of making the technical solution of the utility model and improvement, all should belong to protection domain of the present utility model.
