Automatic attaching medical ice bag

Abstract

The utility model discloses an automatic fitting medical ice bag which comprises an ice bag body with a built-in one-way water channel, a liquid inlet channel, a liquid return channel and a fixing band, and a left forehead treatment part, a right forehead treatment part, a left temporal treatment part and a right temporal treatment part are connected into a whole through bridge connection. Materials forming the two faces of the ice bag body are different in expansion flexibility under the action of cold / hot media, so that the one-way water channels of the left temporal treatment portion and the right temporal treatment portion naturally form curved surface changes to be tightly attached to the corresponding treatment portions after the media pass through the one-way water channels. The size and the bending degree of the one-way water channel are different in the left temporal treatment part and the right temporal treatment part, and the expansion degree is inconsistent in the medium filling state, so that the appearance of the ice bag body is changed in a curved surface mode. A plurality of groups of bridge connections are provided and are respectively connected with each treatment part. The pipe diameter difference exists between the liquid inlet channel and the liquid return channel, so that it is ensured that the ice bag body is in a continuous filling state.

Description

Technical Field

[0001] The utility model relates to cooling equipment, in particular to an automatically fitted medical ice bag. Background Art

[0002] At present, all conventional ice packs, fever patches and other cold and hot treatment products on the market are rectangular or quasi-rectangular, and can only touch the patient's forehead when used. Although the forehead has a certain cooling effect on patients with fever, the treatment point is limited to the superficial surface of the head, and the effect is slow, and it fails to achieve the most effective significance and purpose in clinical use. From the perspective of clinical medicine and physiological anatomy, fever increases the temperature deep in the brain, reduces the hypoxia tolerance of brain cells, and easily causes brain cell damage. At the same time, it promotes excessive secretion of harmful substances such as acid in brain tissue, causing patients to be irritable, convulsive, and even convulsive. Therefore, lowering the temperature deep in the brain of patients with fever is of very necessary clinical significance.

[0003] The "superficial temporal artery" and "superficial temporal vein" pass through the left and right temporal parts of the human body and reach the brain. According to research, cooling the "superficial temporal artery" can quickly transfer the coldness of the cold medium to the deep layers of the brain, while at the same time taking away the heat brought by the "superficial temporal vein" through the cold medium, which is more effective and faster than cooling the forehead alone.

[0004] Due to the physiological curvature of the left and right temporal parts of the human body, and the different curvatures and shapes of different human bodies, the structures of various cooling products currently on the market cannot fit closely to this part during use to achieve the physical effect of effective heat exchange. This is due to many difficulties in structural design. Therefore, all products currently on the market cannot cover the left and right temporal parts of patients and cannot play a critical and effective cold therapy role.

[0005] In view of this, a new technology that can lower the position of the temporal treatment part and combine structural differences such as the size and curvature of the one-way water channel to make the filling and expansion state inconsistent in different positions, so that the shape of the ice pack body produces different shapes of curved surfaces, thereby closely fitting the treatment part, has groundbreaking clinical significance in the industry.
