The invention discloses a regulation and control type hematology department blood transfusion auxiliary device which comprises a universal wheel base, a regulation and control screen, a temperature control heating pipe, a blood transfusion bag hanging system, a blood transfusion bag translation transmission system and a blood transfusion bag uniform heating rotating system. The regulation and control screen is movably installed at the upper end of the universal wheel base through a lifting rod, and a fixing base is fixedly arranged between the regulation and control screen and the lifting rod. The heating rationality is remarkably improved, and the heating intensity and the blood bag moving speed can be flexibly adjusted according to clinical blood transfusion requirements through cooperative operation of rotation of the temperature control heating tube and horizontal reciprocating translation of the blood transfusion bag in combination with precise regulation and control of the regulation and control screen, the temperature sensor and the single-chip microcomputer circuit; the problem that the local temperature is too high or too low due to traditional fixed-point heating is solved, it is ensured that the blood heating temperature always fits the tolerance range of the human body, adverse reactions such as intolerance of cold and shivering caused by low-temperature blood transfusion are effectively reduced, and blood transfusion safety is guaranteed.

This utility model relates to an intraoperative warming bag, comprising an inner liner and an outer liner. The outer liner comprises several interconnected outer liner units, each comprising an outer insulating layer, an insulating layer, and an inner insulating layer arranged sequentially from the outside to the inside. The outer insulating layer and the inner insulating layer at the edge of the outer liner unit are heat-fused to form a heat-fused indentation. The warming bag is provided with several air supply sections, including vents opened on the outer liner units and detachable seals on the vents. After the seals are opened, heated gas is delivered through the vents between the inner and outer liners to heat and keep the patient warm. This invention provides a warming bag that can heat and keep the patient warm during surgery, while ensuring that the unoperated parts of the patient's torso and limbs are covered, thus avoiding postoperative hypothermia, shivering, slow metabolism, and delayed awakening.

The application discloses a cardiovascular interventional operation contrast agent heater and belongs to the field of contrast agent heating. The cardiovascular interventional operation contrast agent heater comprises a bottom plate, a heating water tank is fixedly connected to the upper surface of the bottom plate, two heat preservation cylinders are arranged on the top of the heating water tank, and a placing disc is arranged in the heat preservation cylinder. A circulating pump is arranged on the upper surface of the bottom plate and located to the right of the heating water tank, the input end of the circulating pump is fixedly communicated with the inside of the heating water tank, a three-way electromagnetic valve is fixedly communicated with the output end of the circulating pump, circulating pipes one are fixedly connected to the front end and the rear end of the output end of the three-way electromagnetic valve, and the circulating pipes one are fixedly connected to the output end of the three-way electromagnetic valve. The device can heat the contrast agent to an appropriate temperature, avoids the discomfort such as blood vessel stimulation and shivering caused by injection of low-temperature contrast agent into the human body, and fundamentally improves the diagnosis and treatment comfort of patients. Meanwhile, the stable heating effect and the uniform contrast agent concentration provide guarantee for the smooth development of cardiovascular interventional operation and improve the diagnosis and treatment quality.

The invention discloses a special quilt for radiotherapy for heat preservation of tissue equivalents and a heat preservation instrument, and the special quilt for radiotherapy for heat preservation of tissue equivalents comprises a quilt body which comprises a heat conduction layer and an isolation layer; a closed opening is formed in the side, away from the heat conduction layer, of the isolation layer, the closed opening can be opened and closed, a containing cavity is formed by the area, corresponding to the closed opening, of the heat conduction layer and the isolation layer, and the containing cavity is used for storing tissue equivalents. One side of the isolation layer of the quilt body is provided with the sealing opening capable of being opened and closed, the containing cavity is formed in the area corresponding to the sealing opening and used for storing the tissue equivalent, part of patients do not need to use the tissue equivalent, but all the patients need to cover exposed skin for heat preservation in the preparation period; therefore, the temperature of the tissue equivalent can be increased in advance by using the body temperature of the patient, when the tissue equivalent needs to be used, stimulation, shivering, shaking and other reactions of the patient can be avoided, potential safety hazards do not exist, and the comfort of the patient in the radiotherapy process can be improved.
