Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical auxiliary equipment, in particular to a contrast agent constant-temperature cup holder for CT / nuclear magnetic high-pressure injectors. BACKGROUND

[0002] Medical equipment is the basic condition for continuously improving the level of medical science and technology, and is an important symbol of modernization. Medical equipment has become an important field of modern medicine. The development of medical equipment determines the development of medicine to a large extent, and even plays a decisive role in breaking through the bottleneck in the development of the medical industry. It is also the most basic element of medical treatment, scientific research, teaching, institutions and clinical disciplines, that is, it includes professional medical equipment and also includes household medical equipment. At present, in the process of diagnosis and treatment, high-pressure injectors are often used to inject contrast agents into the body of patients to enhance the clarity of imaging and improve the effect of diagnosis and treatment. However, the current contrast agents have the following problems when in use: 1. The injected contrast agents are generally stored in a constant-temperature box. Long-term high-temperature storage can cause damage to the contrast agents. Moreover, the stored contrast agents are easily affected by the environment after being taken out and injected into the syringe, especially in winter. The temperature of the contrast agents is much lower than the body temperature of the human body. At this time, the over-cooled contrast agents can cause adverse reactions in the human body, which ultimately affects the health of the patients and the effect of diagnosis and treatment; 2. The handrails of the current high-pressure injectors are not convenient to adjust in height, which is not conducive to the movement of medical staff of different heights and reduces the use comfort.

[0003] A constant-temperature storage box for storing contrast agents is disclosed in Chinese Patent Publication No. CN108703767A. The constant-temperature storage box uses multiple electronic chips to control the temperature of the inside of the heat preservation equipment, thereby achieving the purpose of preserving the contrast agents.

[0004] However, in the prior art in the related field, the contrast agent is a viscous liquid, and its specific heat capacity is relatively large. The method disclosed in the prior art is a fixed storage method, which is easy to cause the temperature of the outside of the container containing the contrast agent to reach the standard, while the central temperature of the contrast agent inside does not reach the standard. When used later, it is still a low-temperature structure. Although the existing technology has a device that can stir the contrast agent, it needs to pour the contrast agent into a special container. Repeatedly pouring the contrast agent can cause secondary pollution of the contrast agent. Moreover, it cannot adaptively increase the shaking amplitude according to the capacity of the contrast agent, and still cannot meet the purpose of constant temperature of the contrast agent. SUMMARY

[0009] Preferably, the bottom plate is slidably connected to the fixed sleeve, and the telescopic rod is slidably connected to the fixed sleeve.

[0010] In this way, the telescopic rod and the bottom plate are pressed downward under the pressure of the thermos cup, and the telescopic rod is slidably connected to the fixed sleeve, so that when the hinge, the spherical universal joint and the telescopic rod rotate, the fixed sleeve is only periodically shaken, and the fixed sleeve does not rotate by itself.

[0011] Preferably, the hinge is connected to the eccentric position of the end surface of the turntable.

[0012] In this way, the eccentric structure can drive the fixed sleeve to swing in a ring shape.

[0013] Preferably, four flexible heating plates are evenly attached to the inner side of the gas bag.

[0014] In this way, when the flexible heating plate is subsequently retracted inward, the fitting effect with the thermos cup is ensured.

[0015] Preferably, the bottom plate is provided with an electric switch on the upper surface.

[0016] In this way, the flexible heating plate and the motor can only be started when the thermos cup presses the electric switch on the bottom plate.

[0017] Preferably, the fixing mechanism further comprises an external hanging assembly installed on the side of the fixing shell.

[0018] In this way, the external hanging assembly is fixed on the medical instrument, which is convenient to use.

[0019] Compared with the prior art, the present application has the following advantages: 1. The shaking mechanism drives the fixed sleeve and the thermos cup inside to periodically shake, so that the heat generated by the flexible heating plate is uniformly transmitted to the internal contrast agent, and because the contrast agent slides, the external heat can be exchanged to the inside, so that the temperature of the contrast agent is more balanced. 2. The sealed thermos cup cooperation device avoids pollution of the contrast agent due to replacement of equipment, and the device can adaptively adjust the shaking amplitude according to the weight of the contrast agent, thereby improving the effect of the device when shaking.
