本发明涉及医疗器械领域，具体涉及一种用于保存造影剂的恒温储存箱。The invention relates to the field of medical devices, in particular to a constant temperature storage box for storing contrast agents.
背景技术Background technique
造影剂，一种为增强影像观察效果而注入到人体组织或器官的化学制品。医院在做CT或MRI时，需要给患者注射造影剂以提高人体组织结构的辨识度，从而协助医生作出精准的诊断。造影剂在处于常温状态时，具有高浓度、高渗透压及高粘稠度等理化特性；若将常温状态下的造影剂注入人体，将增加被注射者的身体不适感，甚至导致造影剂外渗的状况发生。而造影剂在处于接近人体温度的状态时，其粘稠度相较于常温状态下的粘稠度，将大幅度下降，从而更有利于造影剂的注射，进而降低被注射者的不适感及造影剂外渗的风险。因此，造影剂在注入人体之前，需对其进行预热，以避免出现上述状况。Contrast agent, a chemical that is injected into human tissues or organs to enhance the viewing effect of images. When hospitals do CT or MRI, they need to inject contrast agents into patients to improve the recognition of human tissue structures, so as to assist doctors in making accurate diagnoses. When the contrast medium is at normal temperature, it has physical and chemical properties such as high concentration, high osmotic pressure and high viscosity; if the contrast medium at normal temperature is injected into the human body, it will increase the physical discomfort of the injected person, and even cause the contrast medium to leak out. seepage occurs. When the contrast agent is in a state close to the temperature of the human body, its viscosity will be greatly reduced compared with the viscosity at normal temperature, which is more conducive to the injection of the contrast agent, thereby reducing the discomfort and pain of the injected person. Risk of contrast medium extravasation. Therefore, before the contrast agent is injected into the human body, it needs to be preheated to avoid the above-mentioned situation.
目前，普遍是将造影剂放置于可加热的水锅中，达到对造影剂进行预热的目的。加热水锅一般包括有锅体、加热组件以及用于放置造影剂的腔体，该腔体与外界相通。如此，造影剂置于腔体后，虽可达到一定程度的预热效果，但由于该腔体与外界相通，将导致腔体内的温度变化较大，无法保证造影剂处于接近人体温度的状态。因其开放性的存储缺点，还导致造影剂长期暴露在辐射环境中；造影剂浸泡在热水中，使用前必须用毛巾擦干造影剂的瓶子，操作不方便；而且存在污染造影剂等医院感染的可能。At present, it is common to place the contrast agent in a heatable water pot to achieve the purpose of preheating the contrast agent. The heating water pot generally includes a pot body, a heating assembly and a cavity for placing a contrast agent, and the cavity communicates with the outside world. In this way, after the contrast agent is placed in the cavity, although it can achieve a certain degree of preheating effect, because the cavity communicates with the outside world, the temperature in the cavity will change greatly, and the contrast agent cannot be guaranteed to be in a state close to the temperature of the human body. Because of its open storage shortcomings, the contrast agent is exposed to the radiation environment for a long time; the contrast agent is soaked in hot water, and the bottle of the contrast agent must be dried with a towel before use, which is inconvenient to operate; and there are hospitals that pollute the contrast agent. possibility of infection.

The preset temperature value of the internal working environment of the box body 1 can be input through the control panel (not shown) outside the box body 1; After completion, the main control chip 4 will control the heater 5 to start to heat the box body 1; and when the temperature value in the box body 1 is heated to the preset temperature, the temperature controller 6 will detect the signal and control the heating The thermostat 5 stops heating; if the temperature in the cabinet 1 falls outside the temperature control range of the preset temperature value, the thermostat 6 will also detect the signal and control the heater 5 to start to heat the cabinet 1 to the preset temperature within the temperature control range. In this way, the constant temperature storage box of the present invention can accurately control the internal temperature of the box body, and can ensure that it is constant at a certain preset temperature value, such as 37°C close to the human body temperature value, making it easier to inject the contrast agent stored in it, and Enhance the tolerance of the injected person to the contrast medium, thereby reducing the physical discomfort of the injected person and avoiding the extravasation of the contrast medium.
在本发明一较佳实施例中，恒温储存箱还包括与主控芯片4电连接的声光报警装置8，其包括设于箱体1上的蜂鸣器81与报警灯82；声光报警装置8在存放腔室111的温度超出预设温度后启动，以发出声光警示。在恒温储存箱启动并输入预设温度值后，加热器5将通过设置在箱体1底部的环形电阻丝或WATLOW陶瓷发热体散发热量，分布至各存放腔室111内，以实现对箱体1内部工作环境的加热升温。在箱体1内部环境温度值达到预设温度时，温度传感器将检测到该信号并发送至主控芯片4进行相应的处理，由温控器6控制加热器5停止加热，使其处于恒温状态。而当箱体1内部温度下降时，PT100温度传感器亦将检测到一个电信号并发送至主控芯片4进行处理，并由温控器6控制加热器5启动，以加热箱体1至预设温度值。同时，在箱体1温度下降时，声光报警装置8启动，通过蜂鸣器81和警报灯82发出警示，以提醒工作人员或管理人员。在检测到箱体1温度下降后，主控芯片4控制通信装置7将该信息发送至服务器，服务器再将其发送至相应的智能终端，用户通过登录智能终端上的APP，可获知该信息。如此，能够有效的对恒温储存箱的温度进行监控，保证放置在其内的造影剂处于37℃的恒温状态，从而使得造影剂的粘度大大降低，有利于造影剂的高压注射，降低被注射者的身体不适感。In a preferred embodiment of the present invention, the constant temperature storage box also includes an acousto-optic alarm device 8 electrically connected to the main control chip 4, which includes a buzzer 81 and a warning lamp 82 arranged on the box body 1; The device 8 is activated after the temperature of the storage chamber 111 exceeds a preset temperature to issue an audible and visual alarm. After the constant temperature storage box is started and the preset temperature value is input, the heater 5 will dissipate heat through the ring-shaped resistance wire or WATLOW ceramic heating element arranged at the bottom of the box body 1, and distribute it into each storage chamber 111, so as to realize the maintenance of the box body. 1 Heating of the internal working environment. When the ambient temperature inside the box 1 reaches the preset temperature, the temperature sensor will detect the signal and send it to the main control chip 4 for corresponding processing, and the temperature controller 6 controls the heater 5 to stop heating, so that it is in a constant temperature state . When the internal temperature of the cabinet 1 drops, the PT100 temperature sensor will also detect an electrical signal and send it to the main control chip 4 for processing, and the temperature controller 6 controls the heater 5 to start to heat the cabinet 1 to the preset temperature. temperature value. Simultaneously, when the temperature of the box body 1 drops, the sound and light alarm device 8 is activated, and a warning is issued through a buzzer 81 and an alarm lamp 82 to remind staff or management personnel. After detecting the temperature drop of the box body 1, the main control chip 4 controls the communication device 7 to send the information to the server, and the server then sends it to the corresponding smart terminal, and the user can learn the information by logging into the APP on the smart terminal. In this way, the temperature of the constant temperature storage box can be effectively monitored to ensure that the contrast agent placed in it is in a constant temperature state of 37°C, so that the viscosity of the contrast agent is greatly reduced, which is conducive to the high-pressure injection of the contrast agent and reduces the risk of the injection. of physical discomfort.
在本发明另一较佳实施例中，箱体1与箱门2之间还设置有硅胶密封条(图未示)。硅胶材料具有良好的密封性能，耐高温，抗老化，抗击打，能够贴合各类光滑表面材质。本发明在箱体1与箱门2之间设置硅胶密封条，能够有效的将外部环境与箱体1内部工作环境隔离，避免外界空气通过箱体1与箱门2之间的间隙进入至箱体1内部，影响箱体1内部工作环境的稳定性，从而影响造影剂的保存温度。In another preferred embodiment of the present invention, a silicone sealing strip (not shown) is also provided between the box body 1 and the box door 2 . Silicone material has good sealing performance, high temperature resistance, aging resistance, impact resistance, and can fit all kinds of smooth surface materials. In the present invention, a silicone sealing strip is provided between the box body 1 and the box door 2, which can effectively isolate the external environment from the internal working environment of the box body 1, and prevent the outside air from entering the box body through the gap between the box body 1 and the box door 2. The inside of the box 1 affects the stability of the working environment inside the box 1, thereby affecting the storage temperature of the contrast medium.
在本发明又一较佳实施例中，箱体1的侧壁具有夹层，夹层中设置有用于隔离外界电磁辐射和/或电离辐射的辐射屏蔽层。造影剂长期暴露于具有一定程度的电磁辐射或电离辐射环境中，将影响造影剂的显影效果。为此，造影剂一般放置在CT室外或MRI室外，避免CT室内产生的电离辐射或MRI室内产生的电磁辐射对其造成影响。然而，造影剂放置在室外，不便于工作人员的拿取，同时，在拿取过程中，通常需走过一段路程后方能到达CT室或MRI室内以对患者进行注射。如此，造影剂本身放置在与外界相通的水锅中进行预热，加之需工作人员提前拿取至CT室或MRI室内，在此过程中，将大大影响造影剂的温度稳定性，从而不利于造影剂的高压注射。本发明恒温储存箱呈封闭设置，通过温控器6能够有效的保证箱体1内的环境温度恒定在造影剂的最佳保存温度，即接近人体温度的37℃。同时，本发明恒温储存箱的侧壁的夹层中设置有用于隔离外界电磁辐射和/或电离辐射的辐射屏蔽层。辐射屏蔽层选用电导率和磁导率较高的导体材料，用作防止MRI室内产生的电磁辐射进入箱体1内；高导电性材料在电磁波的作用下将产生较大的感应电流，该感应电流按照楞次定律将削弱电磁波的渗入；电磁波在渗入金属导体时将不断衰减，直至为零，衰减的程度随金属导体的电导率、磁导率及电磁波频率的增加而增大。而选用原子系数较高的屏蔽材料，常用铅或含铅的物质，用作防止CT室内产生的电离辐射(X射线、γ射线)进入至箱体1内；射线在穿透物质时，其强度亦会减弱，一定厚度的屏蔽物能减弱射线的强度，为此，在恒温储存箱侧壁的夹层中设置一定厚度的铅板，能够有效的降低射线的强度，从而保证箱体1内存储的造影剂不受其影响。如此，本发明恒温储存箱能够放置在CT室或MRI室内，便于工作人员的拿取及造影剂的高压注射。In yet another preferred embodiment of the present invention, the side wall of the box body 1 has an interlayer, and a radiation shielding layer for isolating external electromagnetic radiation and/or ionizing radiation is arranged in the interlayer. Long-term exposure of the contrast agent to a certain degree of electromagnetic radiation or ionizing radiation environment will affect the imaging effect of the contrast agent. For this reason, the contrast agent is generally placed outside the CT room or the MRI room to avoid the impact of ionizing radiation produced in the CT room or electromagnetic radiation produced in the MRI room. However, the contrast agent is placed outside, which is inconvenient for the staff to take. At the same time, in the process of taking it, it usually takes a certain distance to reach the CT room or MRI room for injection to the patient. In this way, the contrast agent itself is preheated in a water pot connected to the outside world, and the staff needs to take it to the CT room or MRI room in advance. During this process, the temperature stability of the contrast agent will be greatly affected, which is not conducive to High-pressure injection of contrast media. The constant-temperature storage box of the present invention is closed, and the temperature controller 6 can effectively ensure that the ambient temperature in the box 1 remains constant at the optimal storage temperature of the contrast agent, which is 37°C close to the temperature of the human body. At the same time, a radiation shielding layer for isolating external electromagnetic radiation and/or ionizing radiation is provided in the interlayer of the side wall of the constant temperature storage box of the present invention. The radiation shielding layer is made of a conductor material with high conductivity and magnetic permeability to prevent the electromagnetic radiation generated in the MRI room from entering the box 1; the high conductivity material will generate a large induced current under the action of electromagnetic waves, and the induction The current will weaken the penetration of electromagnetic waves according to Lenz's law; electromagnetic waves will continue to attenuate when they penetrate into metal conductors until they reach zero, and the degree of attenuation increases with the increase of the conductivity, magnetic permeability and frequency of electromagnetic waves of metal conductors. And the shielding material with higher atomic coefficient is selected for use, commonly used lead or lead-containing substances are used to prevent ionizing radiation (X-rays, γ-rays) generated in the CT room from entering into the cabinet 1; when the ray penetrates the material, its intensity It will also be weakened, and a shield with a certain thickness can weaken the intensity of the rays. For this reason, a lead plate with a certain thickness is set in the interlayer of the side wall of the constant temperature storage box, which can effectively reduce the intensity of the rays, thereby ensuring that the stored in the box 1 Contrast media are not affected by it.
