Description

A kind of absorbable gelatin sponge

Technical field

The utility model relates to a kind of styptic sponge, in particular to a kind of absorbable gelatin sponge belongs to field of medical materials.

Background technique

With the development of society, requirement of the people to wound hemostatic material is higher and higher.Protide absorbable hemostasia material Material is considered as one of most effective bio-medical hemostatic material of partial trauma, has absorbable, efficient, economy and nonhazardous etc. Advantage, it mainly passes through own material feature and advantage, adsorbs blood, and gel blood platelet blocks blood vessel, and fibrin ferment is promoted to produce It is raw, to reach anastalsis.The hemostasis of bio-medical material generally comprises three aspects at present, (1) material itself Absorbency can rapidly absorb oozing of blood, can be fitted on wound after swelling, block blood vessel and generate certain pressure, rise to wound It is acted on to hemostasis by compression；(2) material itself can adsorb blood platelet, make its adhesion and aggregation in wound, block blood vessel；(3) promote The generation of fibrin ferment reaches the final purpose of hemostasis.

Currently, the dental problems such as wisdom tooth, need to treat tooth, in the course of surgery or after operation, need in tooth Fill haemostatic medicament in hole, typically directly filling is mixed with the cotton balls of drug, but the cotton in wound healing, on cotton balls Silk is contacted with the wound to heal, and when taking-up can generate feeling of pain, and will affect the healing of wound, and can only be taken by doctor Out, the puzzlement and inconvenient problem in user's use are caused.

Embodiment: as shown in Figs. 1-2, the utility model provides a kind of absorbable gelatin sponge, including gelfoam ontology 1, Gelfoam ontology 1 includes sponge substrate 101 and the gelatin lamina reticularis 102 for being wrapped in 101 surface of sponge substrate, gelatin lamina reticularis 102 are cross-linked into made of the flexible sponge-like material of reticular structure for gelatin molecule；Being laid on gelfoam ontology 1, there have to be several Micropore 2 is interconnected between micropore 2；Gelfoam ontology 1 is respectively arranged with strip of paper used for sealing 3 and drawstring 4 on same side, and strip of paper used for sealing 3 exists It is freely overturn on gelfoam ontology 1, drawstring 4 is installed in 1 side of gelfoam ontology, can according to need decision drawstring in this way 4 length, in this way can the place special in 1 user of gelfoam ontology can terminate in repair time such as wisdom tooth part Gelfoam ontology 1 oneself is removed afterwards, goes to hospital certainly, it is also very convenient that doctor, which takes out gelfoam ontology 1 by drawstring 4, , while strip of paper used for sealing is set in the side of drawstring 4, drawstring 4 can be placed in the card slot of strip of paper used for sealing 3, then be sealed using strip of paper used for sealing 3, As with 102 material of gelatin lamina reticularis being due to strip of paper used for sealing 3, gelfoam ontology 1 can't be had an impact.

Medicine layer 5 is filled with inside sponge substrate 101, medicine layer 5 is communicated with the outside by micropore 2；Sponge substrate 101 is Hydrophilic polyurethane foam material；Drawstring 4 is fixed in the mounting hole on gelfoam ontology 1；The material and gelatin net of strip of paper used for sealing 3 102 material of shape layer is consistent.

The utility model gelfoam ontology 1 its mainly use and sponge substrate 101 and be wrapped in outside sponge substrate 101 Gelatin lamina reticularis 102, gelatin lamina reticularis 102 are contacted with surface of a wound bleeding part, and because sponge substrate 101 and gelatin lamina reticularis 102 all have sponge spring function, slightly press bleeding part, reach anastalsis using physics compressing, and gelatin is netted Layer 102 has stronger absorption liquid functional, and the part jelly generated while absorbing liquid, which plays closure blutpunkte, to be stopped The effect of blood；General haemostatic medicament is filled with inside the sponge substrate 101, and can be with other care drugs one on its surface It rises and uses, the same styptic sponge is suitable for the hemostasis and shield wound of body surface wound hemorrhage caused by wound, is arranged in sponge substrate Care drug inside 101 is solid in the case where water is encountered, and melts immediately once meeting water, directly passes through gelfoam sheet Micropore 2 on body 1 is contacted with wound, and sponge substrate 101 is hydrophilic polyurethane foam material, can provide relatively good bullet Property and water imbibition sponge, the gelatin lamina reticularis 102 wrapped up outside sponge substrate 101, be using advanced preparation process, will The gelatin molecule of script straight chain is cross-linked into white, light, flexible, the porous flexible sponge-like material of reticular structure, and it is certainly Microporous connectivity on the micropore and sponge substrate that body has, except with preferable gas permeability, moreover it is possible to preferably absorption wound exudate；Though Right gelatin lamina reticularis 102 characteristic no with sponge base 101, but the manufacturing cost of gelatin lamina reticularis 102 is much higher than simultaneously Sponge base 101, and in medicine nursing, it is only necessary to it can reach on 1 surface of gelfoam ontology with gelatin lamina reticularis 102 The effect that user wants, and it is also completely enough using sponge base 101 inside gelfoam ontology 1, and substantially reduce Use cost.

The gelatin-like material and human body body contained in gelatin lamina reticularis 102 is suitable with theoretical content in body tissue, bright Glue lamina reticularis 102 itself can activated macrophage, the reticular structure energy that can be improved the aggregation of blood platelet and leucocyte, and be formed The aggregation of blood platelet is promoted to feel the release for accelerating coagulation factor, so that the surface of a wound be accelerated to stop blooding.

There is the perforation of several penetrabilities on 1 loose and porous inner surface of gelfoam ontology, surface, and the perforation of intermediate penetrability is advantageous In the discharge of sepage, the accumulation of sepage can be reduced by the oily yarn on the reparation sponge of replacement covering wound, protects the surface of a wound Cleaning is held, hydrops drainage can be carried out to avoid the more surface of a wound of hydrops or sample is opened into caused secondary insult, to wound Healing play facilitation.It can also be used in the reparation of damage of skin surface caused by the burn of the more II degree of sepage, scald etc..

Finally, it should be noted that the above is only the preferred embodiment of the utility model, it is not limited to practical It is novel, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art, It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc. With replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all include It is within the protection scope of the utility model.
