Description

Technical Field

[0001] The utility model relates to the technical field of operating tables, in particular to a constant temperature warming device for an operating table. Background Art

[0002] During the operation period, a slight decrease in body temperature may damage the immune function of the bone marrow, but severe hypothermia will cause the immune regulation function to decline more severely. Secondly, the incidence of chills is higher. This is because when the patient has a low body temperature, the body's oxygen consumption and cardiovascular blood supply will increase, which will cause the patient to have chills, wound pain, and increase the use of analgesics. Furthermore, it will affect the patient's coagulation function. This is mainly because low body temperature will cause a decrease in platelet function and impair coagulation function. Therefore, the warmth of surgical patients must be maintained throughout the operation. Not only should attention be paid to avoiding the occurrence of hypothermia in patients during surgery, but warming measures must also be taken before and after surgery.

[0003] At present, the operating table uses a warming pad to accelerate the insulation of the operating table, and also keeps the patient warm to prevent accidents caused by hypothermia during the operation. However, the existing surgical warming pads still have shortcomings when used: first, after preoperative anesthesia, the patient's blood flow slows down, especially the blood circulation at the extremities is slower, and it is difficult to quickly warm up the patient's limbs only by keeping warm with a surgical pad, which will make the patient feel cold or even shiver during the operation, and will also affect the anesthesia recovery after the operation; secondly, when the surgical warming pad is in use, a disposable sterile pad towel needs to be laid, but when the patient lies on the operating table, the disposable sterile pad towel is easy to slide, which often results in the disposable sterile pad towel not completely covering the warming pad, which not only affects the patient's comfort, but also may cause contamination to the warming pad during the operation, and even cause cross-infection among patients.

[0004] In summary, there is an urgent need to design a constant temperature warming device for an operating table that overcomes the above-mentioned problems. Utility Model Content
