Description

Medical cooling oral mucosa cold compress device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a medical cooling oral mucosa cold compress device.

Background

The blood vessel can be contracted and the cells can be anoxic by oral cavity cooling. For oral surgery, low temperature allows the capillary vessels around the wound to contract, which can relieve local congestion and bleeding, inhibit the activity of cells, reduce the sensitivity of nerve endings to relieve pain, reduce local bleeding, reduce the activity of bacteria and the metabolism of cells, thereby preventing inflammation and even the diffusion of suppuration.

Radiotherapy is a local treatment method for treating tumors, for a patient who looks at the head, neck and face, oral mucosa belongs to an acute reaction tissue and pain nerve receptors are more, water molecules are ionized by rays in radiotherapy, oxygen radicals are generated to damage DNA of oral cells and shed epithelial cells, so that oral congestion, edema, erosion and ulcer are caused, and the patient feels pain in the oral cavity and has difficulty in eating. The patient can not insist on continuous irradiation, the pain of the patient is increased, the treatment course is prolonged, and the curative effect is influenced. The oral mucosa can be vasocontracted through oral cavity cooling, the oxygen content of the mucosa tissue is reduced, and the reaction to radiation or external energy is weakened, so that the damage to the oral mucosa is protected and alleviated.

In the existing clinic, the common mode of reducing the temperature of the oral cavity is that the patient usually holds ice cubes, but the defect of poor tolerance of the patient holding the ice cubes exists, the temperature retentivity is poor, the cooling effect of the oral cavity cannot be guaranteed, and the curative effect cannot be guaranteed. And the temperature of the oral cavity is reduced in the treatment process, certain interference is generated in the treatment process, and a certain treatment space is occupied, so that the convenience of operation of an operator is reduced.
