Medical ice blanket

Abstract

The invention discloses a medical ice blanket. The medical ice blanket comprises an ice blanket body. A water circulation pipe is arranged in the ice blanket body and communicated with a water outlet pipe and a water return pipe. The surface of the ice blanket body comprises a cooling region for supporting a human body and an air cushion region located on the periphery of the cooling region. The surface of the ice blanket body is connected with an outer cover in a sealed mode. The cooling region is attached to the outer cover. A compressible cavity filled with air is formed between the air cushion region and the outer cover. The outer portion of the ice blanket body is provided with an inflation and deflation device communicated with the cavity. According to the scheme, an air layer is arranged in the region where the human body can not make contact with the ice blanket, and the air layer isolates air convection between the surface of the ice blanket body and the outside air, so that heat exchange between the air cushion region and the outside air is reduced, and then the temperature difference between the outer surface, corresponding to the air cushion region, of the outer cover and the outside air is reduced; consequently, the medical ice blanket lowers the probability of dew formation of the outer cover, reduces waste of electric energy and can also protect a patient against bedsores.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical ice blanket. Background technique [0002] At present, in clinical medical treatment, mild hypothermia therapy has been paid more and more attention. In the prior art, tools such as ice blankets and ice caps are generally used to realize mild hypothermia therapy. The specific implementation method is to use an ice blanket or ice cap to contact the patient, thereby cooling the body surface. [0003] Traditional ice blanket structures such as figure 1 with figure 2 As shown, it generally includes ice blanket main body 01, return water pipe 02 and outlet pipe 03 and other structures. The ice blanket main body 01 is connected to the main engine refrigeration device through the return water pipe 02 and the water outlet pipe 03. The inside of the ice blanket is covered with pipelines for water circulation. The host refrigeration device controls the water circulati...

AI Technical Summary

Problems solved by technology

PVC plastic will become very hard when used in a low temperature environment, and it is prone to cracks, and water will leak in the cracks, so it is easy to age and has a short life

[0005] In the actual use process, the traditional ice blanket will produce a large amount of condensation water while cooling the patient, which is easy to wet the mattress. The wet mattress is not conducive to the recovery of some patients (such as patients who have just finished surgery). Lying on a wet hospital bed can also cause bedsores

In addition, the existing ice blanket has a certain area, and when the patient lies on the ice blanket, some parts of the ice blanket are not in contact with the human body. These parts will exchange heat with the outside air on the surface of the ice blanket for a long time, which will cause The frequency of starting the water cycle of the refrigeration unit of the ice blanket main engine becomes higher, which leads to the waste of electric energy
