Description

Thermosensitive medical film

Technical Field

The utility model relates to a medical film technical field especially relates to a medical film of heat sensitivity.

Background

The medical film is a medium for bearing medical image and text information and is used as an auxiliary tool for medical staff to diagnose the state of an illness, and the initial medical film is an X-ray film, namely a blue-sensitive film and a green-sensitive film; with the development of hospital digitization, digitized medical films have become the first choice for hospitals. Currently, only a few small, primary hospitals are still using X-ray film, and most hospitals have used digitized medical film instead of blue-green film. The existing common digital medical films comprise medical dry laser films, thermal sensitive films and medical printing films, and the thermal sensitive films have the characteristics of small fog, high definition, high density, bright color and convenient use, and are widely applied in the medical field. Therefore, the color product can be quickly decomposed under the action of long standing time, long illumination time, long heating time, high environmental temperature, moist environment, contact with gummed paper and other external conditions, so that the image and text fading is accelerated. The service life of the thermosensitive film is influenced, and therefore, the Chinese utility model with the authorization publication number of CN216331004U discloses a thermosensitive medical laser film, which comprises a film base and a protective component; film base: its upper surface is provided with anti-halation layer, anti-halation layer is acetylene black anti-halation layer, and the upper surface on anti-halation layer is equipped with the formation of image layer, the formation of image layer is N-isopropyl acrylamide formation of image layer, and the thickness on formation of image layer is 0.03mm, and the upper surface on formation of image layer is equipped with high temperature resistant layer, high temperature resistant layer is ceramic fiber and the compound high temperature resistant layer of epoxy, and the thickness on high temperature resistant layer is 0.02mm, this utility model discloses a through setting up the heat resistance of high temperature resistant layer reinforcing heat-sensitive film, and then make the life of this film longer, but, to heat-sensitive film, its preservation is generally deposited in the shade, makes its environment that often that fades more easily be moist, this also is the important factor that influences heat-sensitive film life, in addition, this utility model production technology is complicated, and high in production cost is unfavorable for heat-sensitive film's popularization and use.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple process, low in production cost, the medical film of temperature sensing formula that can be dampproofing.

The technical solution of the utility model is that:

a heat-sensitive medical film comprises a film base, wherein a heat-sensitive layer, a protective layer and a PE film are arranged on each of two surfaces of the film base from inside to outside; the thermosensitive layer is coated on the film base, the thermosensitive layer is coated with a protective layer, and a PE film is bonded outside the protective layer.

Further, the base sheet is a blue polyester base sheet.

Further, the material of the protective layer is acrylic resin.

Further, the PE film is bonded on the protective layer through transparent resin glue.

Further, the PE film sealing device further comprises a sealing strip, and the sealing strip is bonded to the edge of the PE film.

The beneficial effects of the utility model are that:

the utility model discloses simple structure, low in production cost, and the PE film has dampproofing effect, can effectively slow down the time that picture and text on the temperature-sensitive material disappear, make its life longer.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

wherein: 1. the film comprises a film base, 2 parts of a thermosensitive layer, 3 parts of a protective layer, 4 parts of a PE film and 5 parts of a sealing strip.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

As shown in fig. 1, the heat-sensitive medical film comprises a film base 1, a heat-sensitive layer 2, a protective layer 3 and a PE film 4, wherein the heat-sensitive layer 2 is coated on the film base 1, the protective layer 3 is coated on the heat-sensitive layer 2, and the PE film 4 is adhered to the outer side of the protective layer 3 by using glue.

In this embodiment, the base sheet 1 is a blue polyester base sheet 1, and the blue polyester base sheet 1 has a high melting point, low shrinkage, high elasticity, good thermal stability, and high chemical stability, and can be used as a base sheet to hold a firm film.

In the embodiment, the thermosensitive layer 2 is formed by combining an adhesive, a color-developing agent and a leuco dye, and when the thermosensitive paper encounters a heating printing head, the color-developing agent and the leuco dye at the printing position of the printing head chemically react to change color to form images and texts; the color developing agent can be any one of polyvinyl alcohol, styrene butadiene polymer, p-hydroxybenzoic acid and esters thereof, salicylic acid, 2, 4-dihydroxybenzoic acid or aromatic sulfone, and producers can select proper materials as the color developing agent according to actual conditions to control the production cost; the leuco dye is any one of crystal violet lactone, a fluorane system, leucobenzoyl methylene blue or a spiropyran system of a trityl phthalide system, and a producer can select a proper material as the leuco dye according to actual conditions so as to control the production cost.
