Description
Technical field
A kind of present invention medical burn wound cooling air-flow interchanger, be related to it is a kind of medically use, wound is carried out
The air-flow exchange apparatus of cooling, belongs to field of medical device.It is more particularly to a kind of by cold airflow wound to be cooled
Air-flow exchange apparatus.
Background technology
At present, after patient's injury of being burnt in medicinal, it is often necessary to cooling processing is carried out to this kind of wound, to slow down
The pain of patient, when being cooled at present using ice bag, it can not be fixed, it is necessary to hand Continued depression, burn site is dropped
Temperature, when burn surface area is more than when ice bag envelope accumulates, it is necessary to be carried out using multiple ice bags, workload is big, and ice bag cooled simultaneously
Condensed water in journey, which can drip wound, causes wound inflammation, and ice bag is when being cooled, heat when due to ice bag structure and using
Amount transmission, medium position temperature is low, cool time length, therefore corresponding wound is also that central temperature spreads to surrounding, is dropped
Temperature, but when burn, the sensation of edge of wound position is most strong, it is necessary to cool at first to marginal position, because
This can coordinate fan to increase air flow so that the temperature uniformity of wound everywhere, but air-flow is directly blown to wound surface
On, air velocity is fast, and temperature is low, and wound can be caused further to injure, and it is the air-flow velocity of wound everywhere that fan, which is blown,
It is inconsistent so that wound cools difference everywhere, the existing method to be cooled by dressing to wound, is by aerogel dressing
Wound site is covered in, but dressing cooling is mostly expendable consumed product, after having used, due to the body containing patient in dressing
Liquid, blood or secretion can not carry out secondary use, not only waste resource, also environment is made, it is necessary to carries out burning disposal
Into very big influence, and the fixation of dressing uses fixing band, and fixed tension causes wound site blood not circulate, and pine causes to apply excessively
Material, which comes off, influences cooling-down effect.
Publication number CN102600018A discloses a kind of medical dressing for having and cooling and promoting wound healing effect, extremely
Include following four part less：Perforated non-woven layer of cloth, there is the layers of nanofibers of gradient-structure, hydrogel layer and supporting layer.This hair
The preparation method of bright medical dressing is：Hydrogel is covered on supporting layer, then is covered with the nanofiber with gradient-structure
Layer, finally reinforce perforated non-woven layer of cloth in nanofiber layer surface and obtain medical dressing, the layers of nanofibers in the invention has
Gradient-structure, reach the surface of a wound beneficial to the absorption and delay of wound fluid, after insoluble drug release and promote wound healing；Perforated non-woven fabric
Acted on physical isolation, avoid extraneous germ from invading, Wound exudate can be absorbed, and be easy to remove from wound surface, no
Wound is adhered to, hydrogel layer can realize the regulation and control of temperature, cool for wound, and it is integrally used as dressing for the invention, and is burnt
Wound directly contacts, although there is the hydrogel that can be cooled to wound, dressing is disposable, and what can not be continued enters
The addition of water-filling gel, temperature is maintained, while hydrogel can not be reclaimed after cooling, be dealt with abnormal troublesome.
Publication number CN205866942U discloses a kind of emergent heat sink of the special burn of marine naval vessels, and it includes some
It is individual to be spliced to form the cooling bag and an at least guiding tube to match with human body outline in order through mutual, during the cooling is wrapped
Provided with cavity, cooling is wrapped provided with the water inlet and delivery port connected with cavity, when cooling bag is with cooling bag splicing, one
The water inlet of bag is cooled down to be connected and communicate with the delivery port directly connection of another cooling bag or by guiding tube；When cooling bag with
When cooling bag does not splice, connected between the water inlet of a cooling bag and the delivery port of another cooling bag by guiding tube, should
Scheme is to be used as cooling medium by seawater, by injection seawater in multiple cooling bags, wound is cooled by seawater, cooled down
Bag and wound directly contact, and exist to wound and pollute, easily cause wound contamination, and need to be dismantled in dressing, fixed
When elasticity be difficult to hold, and chilling temperature is radiated from water inlet along drainage tube direction, is not entered according to wound characteristic
The setting of the capable scheme that cools.
Publication number CN1411790 discloses a kind of first-aid cooling bag, the cooling bag be by bag built with cooling compound and
Pouch composition equipped with reaction solution, wherein cooling compound is nitrate and urea hydrochlorate, reaction solution be by sodium carboxymethylcellulose,
Radix Et Rhizoma Rhei extract, rhizoma extracting liquid and water composition, the program absorb outside heat progress wound cooling, cooling by chemically reacting
Shape has nitrate and urea hydrochlorate in reaction bag, is heat absorption water suction during course of reaction, once leaking, can to hinder
The moisture of mouthful position is by reactive absorption, the problems such as causing wound dehydrates, while directly and Wound contact, needs to dismantle after the reaction
Change reactant.
Publication number CN105078646A discloses a kind of ice compress, it include N number of monomer receiving bag (receiving 1 ice pack) and
N number of monomer fixing band, ice pack is fixed on by wound site by fixing band, realizes the purpose of wound cooling, but this method is adopted
With ice pack, after refrigerant has used, can not directly be added, between ice pack is dismantled after changed, dismantle
Complexity, trouble.
