Abstract

A disposable self-heating application matched with a blunt needle comprises a self-heating layer and an application layer, wherein a self-heating material is arranged on the self-heating layer, a dressing is arranged on the application layer, and the dressing is a sterile water-absorbing material. The application layer is further provided with an anti-seepage ring and an anti-seepage film, and the anti-seepage ring and the anti-seepage film isolate the dressing from the application layer.

Description

Disposable spontaneous heating is applied ointment or plaster that cooperation blunt needle was used

Technical Field

The invention relates to a self-heating type application, in particular to a disposable self-heating application matched with a blunt needle for use in a hospital.

Background

The arteriovenous internal fistula is a 'life line' of a maintenance dialysis patient and is a fatal weak link of the patient, the puncture success rate can be effectively improved by a buttonhole blunt needle puncture method, the pain and anxiety of the patient are reduced, the pain and anxiety score of the patient is reduced, and the beauty of the punctured local skin of the internal fistula is improved. And simultaneously reduces complications. According to the requirements of the 2015 blood vessel access nursing operating manual for hemodialysis: before each puncture, a nurse heats the puncture needle to 40 ℃ by using sterile gauze alcohol, the scab skin is applied for about 30 minutes in a wet and hot way, and then a sterile cotton swab is used for directly removing the scab skin and twisting the scab skin into a blunt needle to enter the blood vessel. However, in clinic, the preparation time before puncture is long, and heating is inconvenient, so that a plurality of medical staff do not need to operate according to the operation instruction before puncture, and moist and hot eschar compression is not carried out, and the eschar junction is still hard. Under the condition, scab knots are removed by using sharp instruments such as a puncture needle, a large needle head and the like, so that the wound surface is enlarged, the infection risk of the internal fistula is increased, the pain of a patient is increased, and a novel object is urgently needed to change the situation.

Disclosure of Invention

In order to solve the problem of irregular operation of medical staff, meet the requirements of an operation guide and enable scab knots before puncture to achieve the softening effect, the invention adopts the following technical scheme.

A disposable self-heating application matched with a blunt needle comprises a self-heating layer and an application layer, wherein a self-heating material is arranged on the self-heating layer, a dressing is arranged on the application layer, and the dressing is a sterile water-absorbing material.

The application layer is further provided with an anti-seepage ring and an anti-seepage film, and the anti-seepage ring and the anti-seepage film isolate the dressing from the application layer.

Preferably, the material of the anti-seepage ring is sponge, and the material of the anti-seepage film is pearlized film.

Preferably, the self-heating layer is wrapped with an air-impermeable film.

Preferably, the self-heating material is iron powder, water, activated carbon, and inorganic salt.

Preferably, the spontaneous heating material is prepared by preparing polymer gel solid electrolyte (SPE) from sodium bromide propionamide and PEG6000 and physically blending the SPE with reduced iron powder and activated carbon.

Preferably, the self-heating material is prepared by preparing Polymer in Salt type Polymer solid electrolyte (SPE) by using urea, thiourea and polyethylene glycol (PEG), and physically blending the SPE with reduced iron powder and activated carbon.

Preferably, the sterile water absorbent material is absorbent cotton.

Preferably, the application layer further comprises a backing layer outside the application layer, the backing layer isolating the application layer from the atmosphere.

Preferably, the material of the application layer is non-woven fabric.

Preferably, the material of the backing layer is a release film.

When the invention is used, the manual heating is avoided, the workload is reduced, and the intermediate links which may pollute articles are reduced; the harm caused by scab picking of the sharp instrument is avoided, and the infection risk is reduced; the convenience and convenience are realized, and the patient can operate the device by himself; small size, easy carrying, cheap material and reduced economic loss.

Drawings

Fig. 1 is an exploded view of the present invention (backing layer cut away).

In the figure: 1-a back lining layer, 2-an application layer, 3-a self-heating layer, 4-a self-heating material, 5-an anti-seepage ring and 6-an anti-seepage film.

Detailed Description

In order to more clearly illustrate the present invention, embodiments of the present invention are further described below with reference to the accompanying drawings.

As shown in the figure, the disposable self-heating application matched with the blunt needle comprises a self-heating layer 3 and an application layer 2, wherein a self-heating material 4 is arranged on the self-heating layer 3, and a dressing (not shown in the figure) is arranged on the application layer and is a sterile water-absorbing material.

The dressing is further provided with an anti-seepage ring 5 and an anti-seepage film 6 on the application layer 2, and the anti-seepage ring 5 and the anti-seepage film 6 isolate the dressing from the application layer 2.

Preferably, the self-heating layer is wrapped with an air-impermeable film.

Preferably, the self-heating material is iron powder, water, activated carbon and inorganic salt; or the spontaneous heating material is prepared by preparing polymer gel solid electrolyte (SPE) from sodium bromide propionamide and PEG6000 and physically blending the SPE, reduced iron powder and activated carbon; or, the self-heating material is prepared by preparing Polymer in Salt type Polymer solid electrolyte (SPE) by using urea, thiourea and polyethylene glycol (PEG), and physically blending the SPE, reduced iron powder and activated carbon.

Preferably, the sterile water absorbing material is absorbent cotton, absorbent cotton balls and absorbent cotton pads.

Preferably, the application layer also comprises a backing layer 1, and the backing layer 1 isolates the application layer 2 from the atmosphere.

Preferably, the material of the application layer 2 is non-woven fabric.

Preferably, the material of the backing layer 1 is a release film.

When the puncture needle is used, before 30 minutes of puncture by a blunt needle, the back lining layer is uncovered, sterile alcohol or iodophor or sterile normal saline is poured on the dressing, the air-impermeable film wrapped on the self-heating layer is uncovered, the self-heating material generates heat after contacting air, the dressing is heated, and then the scab knot is heated, and is softened under the hot compress of the dressing with damp heat, so that the puncture needle is ready for next puncture.

The invention is convenient and convenient, and the patient can operate by himself; the workload of manual heating and the intermediate link that the manual heating may pollute the articles are avoided; optionally adding disinfectant and solvent for patients, especially physiological saline for patients allergic to alcohol iodophor; the harm caused by scab picking of the sharp instrument is avoided, and the infection risk is reduced; small size, easy carrying, cheap material and reduced economic loss.
