Description

Remaining needle pad pasting Technical Field The application relates to the technical field of medical appliances, in particular to an indwelling needle pad pasting. Background The use of keeping somewhere the needle can reduce the suffering that the infant caused because of the repeated venipuncture and to the fear sense of taking the needle, alleviate the dysphoria mood of head of a family, be convenient for clinical medicine, emergency, critical patient's rescue is taken medicine, alleviate nurse's work load, reduce infant pain, therefore the vein keeps somewhere the needle and is in clinical wide application, keep somewhere the needle pad pasting along with the progress of technology and keep somewhere the needle pad pasting and be born with the beginning, keep somewhere the needle pad pasting and possess effectively reduce the infection risk, fixed keep somewhere the needle, protect puncture position and improve functions such as patient's comfort level, adopt ordinary transparent pad pasting in the clinic, the pad pasting covers on the vein and keeps somewhere the needle, the rubberized fabric is fixed again. In clinical use, when a patient sweats, seeps or contacts water stains, liquid is easy to infiltrate into a glue layer along the edge of the film, so that colloid is hydrolyzed and loses efficacy, the viscosity of the edge is obviously reduced, and meanwhile, capillary action is generated after the edge is tilted, so that the liquid is accelerated to diffuse towards the center, and the viscosity firmness degree is directly influenced. Disclosure of utility model The application provides a retaining needle film, which aims to solve the technical problems that in clinical use, the inventor realizes that when a patient sweats, seeps or contacts water stains, liquid is easy to infiltrate into a glue layer along the edge of the film, so that colloid hydrolysis is invalid, the adhesiveness of the edge is obviously reduced, and capillary action is generated after the edge is tilted, so that the liquid is accelerated to spread towards the center, and the adhesiveness firmness degree is directly influenced. The application provides an indwelling needle film which comprises a packaging film, wherein a communicating empty groove and a limiting hole are formed in the packaging film, a multi-layer film assembly is sequentially arranged on the inner wall of the empty groove, a limiting pad is arranged on the inner wall of the limiting hole, the limiting pad is provided with an inlet and a placement interval, the width of the inlet is limited to the maximum width of the placement interval, the limiting pad is made of an elastic material, an adhesive film is arranged on the back surface of the packaging film, a water absorbing film is arranged on the back surface of the packaging film and positioned outside the adhesive film, and tearable films are arranged on the surfaces of the water absorbing film and the adhesive film. In any of the above technical solutions, further, the multi-layer film assembly includes a skin contact layer, a drug release layer, a stress buffer layer, and a surface protection layer, where the skin contact layer, the drug release layer, the stress buffer layer, and the surface protection layer are sequentially disposed from the back side of the encapsulation film to the front side of the encapsulation film. In any of the above technical solutions, further, ventilation holes are formed in the skin contact layer, the drug release layer, the stress buffer layer, and the surface protection layer. In any of the above technical solutions, further, the inside diameter of the ventilation holes of the skin contact layer, the drug-releasing layer, the stress buffer layer, and the surface protection layer is gradually reduced in size. In any of the above aspects, further the front surface of the tearable membrane is in contact with the skin contact layer. In any of the above solutions, further, the tearable membrane does not block the inlet. In any of the above embodiments, further, the stress buffer layer is in a honeycomb structure. In any of the above technical solutions, further, the skin contact layer is made of any one of medical silica gel and hydrocolloid. In any of the above technical solutions, further, the material of the drug-release layer is any one of agarose and polyacrylamide. In any of the above technical solutions, further, the water absorbing film is made of polypropylene. The beneficial effects of the application are mainly as follows: The sweat, seepage and water stain and other liquids at the edge of the packaging film are adsorbed in advance by the water absorption film, so that the contact between the liquid and the adhesive film is avoided, the fixing firmness of the adhesive film is further ensured, meanwhile, the weight of the water absorption film is increased after water absorption, and the packaging film can be more adhered to the skin of a patient when the patient lies
