Cold and hot wet compress device

Technical Field

The invention relates to the technical field of medical appliances, in particular to a cold and hot wet compress device.

Background

Because magnesium sulfate has pharmacological actions of hypertonicity, detumescence and analgesia, magnesium sulfate solution is often used for carrying out hot compress detumescence. In general, magnesium sulfate is mixed with water to prepare 50% magnesium sulfate solution, heated to about 40 deg.C, soaked in gauze pieces, and applied to affected parts. And then a layer of plastic film is covered, or a hot water bag is used for pressing to strengthen the heat preservation.

However, the time for performing one-time wet compress is about 20-30 minutes, and the temperature of the gauze and the humidity of the magnesium sulfate solution are continuously reduced along with the time increase, so that the gauze needs to be replaced regularly in one-time hot compress process. The mode clearly increases the workload of medical staff, and meanwhile, after the gauze is taken away from the affected part, the suddenly generated alternating temperature difference between cold and hot can cause a certain influence on the sensitive affected part.

Disclosure of Invention

The technical problem solved by the invention is to provide the cold and hot wet compress device which can reduce the workload of medical staff and improve the experience of patients.

The basic scheme provided by the invention is as follows: including heating cabinet and atomizer, stock solution portion has been seted up to the inside heating cabinet, the feed inlet of intercommunication outside and stock solution portion has been seted up at the top of heating cabinet, atomizer and stock solution portion bottom intercommunication, atomizer still communicates there is a fog pipe, the other end of a fog pipe is equipped with the shower nozzle.

The principle and the advantages of the invention are as follows: when the magnesium sulfate solution is used, water is filled into the heating box, and magnesium sulfate is put into the liquid storage part of the heating box from the feed inlet and mixed to form the magnesium sulfate solution. The magnesium sulfate solution in the liquid storage part is heated through the heating box, the heated magnesium sulfate solution is introduced into the atomizing device, the atomizing device converts the magnesium sulfate solution into a water mist form, the water mist is led out through the mist outlet guide pipe, the water mist is discharged to the spray head along the mist outlet guide pipe, and the spray head is aligned to an affected part for wet and hot compress.

Compared with the prior art, the gauze does not need to be replaced at intervals, and the wet-hot compress can be continuously carried out on the affected part in one hot compress treatment course, so that the workload of medical staff is reduced, and meanwhile, the experience of a patient is improved.

Further, atomizing device includes the atomizing case, the heating cabinet bottom is seted up flutedly, in the recess was located to the atomizing case, import and export have been seted up to the both sides of atomizing case, the import is through feed liquor pipe and stock solution portion intercommunication, import department is equipped with the solenoid valve, export and play fog pipe intercommunication, be equipped with ultrasonic atomizer in the atomizing case.
