Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a contrast medium constant temperature box. Background Art

[0002] Contrast agents are chemicals injected (or ingested) into human tissues or organs to enhance imaging. These agents have a higher or lower density than surrounding tissue, creating a contrast that allows images to be displayed using certain instruments, such as iodine preparations and barium sulfate, commonly used for X-ray observation.

[0003] Before use, contrast agents need to be heated to a temperature close to human body temperature (such as 37°C) to reduce their viscosity, make injection smoother, and reduce patient discomfort. Heating contrast agents not only increases the absorption rate of the drug, thereby improving the efficiency of the examination, but also effectively prevents adverse reactions and reduces the occurrence of side effects. Contrast agents are generally heated to the required temperature in a constant temperature box. Contrast agents are stored in the constant temperature box in a stacked manner. Although the temperature in the constant temperature box has reached the required temperature, the contrast agent in the middle is blocked, and it is impossible to ensure that all contrast agents are at a temperature close to human body temperature. Medical staff need to soak the contrast agent in hot water to reach the required temperature, which increases the workload of medical staff. In addition, it is difficult to accurately control the temperature when heating the contrast agent with hot water. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a contrast agent constant temperature box, which can uniformly maintain the temperature of the contrast agent and ensure that each contrast agent can be at the required temperature.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A constant temperature box for contrast media, comprising a box body, a placement cavity provided in the box body, a box opening communicating with the placement cavity provided on one side of the box body, and a door provided on the box body to seal the box opening;

[0007] A plurality of mounting plates are arranged at intervals in the placement cavity to divide the placement cavity into a plurality of placement grids. A first cavity is arranged in the mounting plates, a heater is fixedly arranged in the first cavity, and a first heating hole communicating with the first cavity is arranged on a side of the mounting plates facing the corresponding placement grids.

[0008] The placement grid is evenly spaced with a number of partitions, a second cavity is provided in the partition, the partition is connected to the corresponding mounting plate, and the second cavity is communicated with the first cavity, and second heating holes are provided on both sides of the partition so that the heat generated by the heater can be discharged through the second heating holes.

[0009] Furthermore, an air inlet cavity and an exhaust cavity are respectively provided on both sides of the placement cavity, the air inlet cavity is conductively connected to the first cavity, and the placement grid is provided with a plurality of exhaust holes conductively connected to the exhaust cavity;

[0010] An air guide cavity is provided on the side of the box body facing away from the box opening, and the two ends of the air guide cavity are respectively connected to the air inlet cavity and the exhaust cavity. A plurality of guide fans are provided at one end of the air inlet cavity close to the air guide cavity, so that the gas passes through the first cavity, the second cavity and the exhaust cavity in sequence and then enters the air inlet cavity.

[0011] Furthermore, a temperature sensor is provided in each of the placement compartments, and the temperature sensor is electrically connected to the heater through a controller.

[0012] Furthermore, the erection plate is arranged at an angle, and the erection plate is inclined toward the bottom of the box body along the direction close to the box opening; the placement grid is provided with a limiting rod, and both ends of the limiting rod are respectively fixedly connected to the inner wall of the placement grid.

[0013] Furthermore, the first heating holes are arranged in multiple columns, and the first heating holes in each column are evenly spaced and have the same number;

[0014] The bottom of the partition is provided with connecting tubes having the same number as the first heating holes in each column, one end of the connecting tube is conductively connected to the second cavity, and the other end of the connecting tube is embedded in the corresponding first heating hole and communicates with the first cavity;

[0015] Handle screws are respectively provided at both ends of the partition. The handle screws are slid through the partition and then threaded into the mounting plate.

[0016] Furthermore, a sealing plug is provided on the outer wall of the connecting pipe. The sealing plug is a truncated cone structure made of rubber material. The narrow end of the sealing plug faces away from the partition, and after the sealing plug is embedded in the first heating hole, the wide end of the sealing plug abuts against the mounting plate.

[0017] Furthermore, one end of the door body is rotatably connected to the box body through a hinge, and the other end is provided with a magnetic plate, which can be adsorbed on the box body so that the door body closes the box opening.

[0018] Furthermore, sealing strips are provided around one side of the door body facing the box opening. When the door body closes the box opening, the sealing strips abut against the peripheral wall of the box opening.

[0019] The beneficial effects of the utility model are:

[0020] 1. By placing the contrast agent between two partitions or between the partition and the box, the contrast agent is evenly arranged in the placement grid. Under the action of the heater, heat can be discharged through the first heating hole to heat the bottom of the contrast agent and maintain a constant temperature. At the same time, since the partition is conductively connected to the mounting plate, the heat of the heater can be discharged through the second heating hole to heat the side of the contrast agent and maintain a constant temperature. By heating the bottom and side of the contrast agent at the same time, the utility model can ensure that each contrast agent in the placement grid can be at the required temperature, and the heating speed is fast, which reduces waiting time.

[0021] 2. Under the action of the guide fan, the gas in the box passes through the first cavity, the second cavity, and the exhaust cavity in turn and then enters the air inlet cavity, so that the heat generated by the heater forms a cycle, which improves the efficiency of heating the contrast agent and allows the heat to be evenly distributed to the storage grid, further improving the uniformity of the constant temperature.

[0022] 3. Due to the tilted mounting plate, the contrast agent near the box opening can slide to the lower part of the mounting plate under its own weight and align with the limit rod, facilitating its removal. Depending on the size of the contrast agent, the connecting tube of the partition is embedded in the first heating hole of the corresponding column, connecting the second cavity with the first cavity. The partition is fixed to the mounting plate with a handle screw, allowing the contrast agent to be sandwiched between the two partitions or between the partition and the box body, preventing the contrast agent from accumulating at the lower part of the mounting plate while ensuring a constant temperature heating effect on the side of the contrast agent.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Please also see Figures 1 to 5 A contrast agent constant temperature box of a preferred embodiment of the present invention includes a box body 1, a placement cavity is provided in the box body 1, a box opening connected to the placement cavity is provided on one side of the box body 1, and the box body 1 is provided with a door body 11 to close the box opening.

[0033] Several mounting plates 2 are spaced apart within the placement chamber to divide the chamber into a plurality of placement compartments 101. A first cavity 201 is disposed within the mounting plates 2. A heater 3 is fixedly disposed within the first cavity 201. A first heating hole 21 communicating with the first cavity 201 is disposed on one side of the mounting plates 2 facing the corresponding placement compartment 101. In this embodiment, the heater 3 is a heating sheet.

[0034] The placement grid 101 is evenly spaced with several partitions 4, a second cavity 401 is provided in the partition 4, the partition 4 is connected to the corresponding mounting plate 2, and the second cavity 401 is connected to the first cavity 201, and second heating holes 41 are provided on both sides of the partition 4 so that the heat generated by the heater 3 can be discharged through the second heating holes 41.

[0035] like Figure 4 As shown, the mounting plate 2 is tilted, sloping toward the bottom of the box body 1 near the box opening. In this embodiment, the tilt angle of the mounting plate 2 is 3°. The storage compartment 101 is provided with a limit rod 6, each end of which is fixedly connected to the inner wall of the storage compartment 101. Due to the tilt of the mounting plate 2, the contrast agent near the box opening can slide to the lower part of the mounting plate 2 under the weight of its own gravity and meet the limit rod 6, thus facilitating the removal of the contrast agent.

[0036] By placing the contrast agent between the two partitions 4 or between the partition 4 and the housing 1, the contrast agent is evenly distributed within the storage compartment 101. Heat from the heater 3 is discharged through the first heating hole 21, thereby heating and maintaining a constant temperature at the bottom of the contrast agent. Simultaneously, because the partition 4 is electrically connected to the mounting plate 2, heat from the heater 3 is discharged through the second heating hole 41, thereby heating and maintaining a constant temperature at the sides of the contrast agent. This embodiment simultaneously heats both the bottom and sides of the contrast agent, ensuring that each contrast agent within the storage compartment 101 is maintained at the desired temperature. Furthermore, the temperature rises rapidly, reducing waiting time.

[0037] like Figure 2 and Figure 3 As shown, an air inlet cavity 12 and an exhaust cavity 13 are provided on both sides of the placement cavity. The air inlet cavity 12 is electrically connected to the first cavity 201, and the placement grid 101 is provided with a plurality of exhaust holes 102 electrically connected to the exhaust cavity 13. In this embodiment, the mounting plate 2 is provided with an opening on one side, which is electrically connected to the air inlet cavity 12 through the opening.

[0038] An air guide cavity 14 is provided on the side of the housing 1 facing away from the housing opening, and the two ends of the air guide cavity 14 are respectively connected to the air inlet cavity 12 and the exhaust cavity 13. A plurality of guide fans 121 are provided on the end of the air inlet cavity 12 near the air guide cavity 14, so that air passes through the first cavity 201, the second cavity 401, and the exhaust cavity 13 in sequence before entering the air inlet cavity 12. In this embodiment, the air inlet cavity 12 is provided with an air inlet, and the guide fans 121 are disposed in the air inlet.

[0039] Under the action of the guide fan 121, the gas in the box 1 passes through the first cavity 201, the second cavity 401, and the exhaust cavity 13 in turn and then enters the air inlet cavity 12, so that the heat generated by the heater 3 forms a cycle, thereby improving the efficiency of heating the contrast agent, and at the same time allowing the heat to be evenly dissipated into the placement grid 101, further improving the uniformity of the constant temperature.

[0040] like Figure 3 、 Figure 4 and Figure 5 As shown, the first heating holes 21 are arranged in multiple columns, and the first heating holes 21 in each column are evenly spaced and have the same number;

[0041] The bottom of the partition 4 is provided with the same number of connecting tubes 42 as each column of the first heating holes 21. One end of the connecting tube 42 is conductively connected to the second cavity 401, and the other end of the connecting tube 42 is embedded in the corresponding first heating hole 21 and communicates with the first cavity 201.

[0042] A handle screw 43 is provided at each end of the partition 4. The handle screw 43 slides through the partition 4 and then threads into the mounting plate 2. In this embodiment, a row of threaded holes 202 are provided on the side of the mounting plate 2 near the air guide cavity 14 and the side near the box opening. The handle screw 43 slides through the partition 4 and then threads into the threaded holes 202, thereby securing the partition 4 to the mounting plate 2.

[0043] The structure of the partition 4 of this embodiment with adjustable position can adapt to contrast agents of different sizes and specifications. According to the different sizes and specifications of the contrast agents, the connecting tube 42 of the partition 4 is embedded in the first heating hole 21 of the corresponding column, so that the second cavity 401 is connected with the first cavity 201, and the partition 4 is fixed to the mounting plate 2 by the handle screw 43 at the same time, so that the contrast agent can be sandwiched between the two partitions 4 or between the partition 4 and the box body 1, avoiding the contrast agent from stacking at the bottom of the mounting plate 2, while ensuring the constant temperature heating effect on the side of the contrast agent.

[0044] like Figure 4 As shown, a sealing plug 421 is provided on the outer wall of the connecting pipe 42. The sealing plug 421 is a truncated cone structure made of rubber material. The narrow end of the sealing plug 421 faces away from the partition 4. After the sealing plug 421 is embedded in the first heating hole 21, the wide end of the sealing plug 421 abuts against the mounting plate 2.

[0045] Under the action of the sealing plug 421, the connection between the connecting tube 42 and the first heating hole 21 is made more closely fitted, ensuring that the heat in the first cavity 201 can be more effectively transferred to the second cavity 401, thereby effectively heating the side of the contrast agent.

[0046] like Figure 1As shown, one end of the door body 11 is rotatably connected to the box body 1 through a hinge 111, and the other end is provided with a magnetic plate 112, which can be adsorbed on the box body 1 so that the door body 11 closes the box opening.

[0047] A sealing strip 7 is provided around the side of the door body 11 facing the box opening. When the door body 11 closes the box opening, the sealing strip 7 abuts against the peripheral wall of the box opening.

[0048] Under the action of the sealing strip 7 , the heat dissipation outside the box body 1 can be reduced, thereby improving the constant temperature heating effect of the box body 1 .

[0049] In this embodiment, each compartment 101 is provided with a temperature sensor 5, which is electrically connected to the heater 3 via a controller. The temperature sensor 5 detects the temperature within the corresponding compartment 101. Based on the temperature of each compartment 101, the controller adjusts the output power of the heater 3 to ensure that each compartment 101 has an appropriate heating temperature, thereby improving the efficiency of achieving the desired contrast agent temperature. The housing 1 of this embodiment is equipped with a control panel for temperature control.

[0050] The use process of the contrast agent constant temperature box in this embodiment is as follows:

[0051] According to the different sizes of contrast agents, the connecting tubes 42 of the partitions 4 are embedded in the first heating holes 21 of the corresponding row to clamp the contrast agent between the two partitions 4 or set between the partitions 4 and the box 1. The controller adjusts the output power of the heater 3 according to the data of the temperature sensor 5.

[0052] Heat generated by heater 3 is discharged through first heating hole 21 to heat and maintain a constant temperature at the bottom of the contrast agent. Simultaneously, heat from heater 3 is discharged through second heating hole 41 to heat and maintain a constant temperature at the sides of the contrast agent. Under the action of guide fan 121, the gas within storage compartment 101 enters exhaust cavity 13 through exhaust hole 102, then passes through gas guide cavity 14, air inlet cavity 12, first cavity 201, and second cavity 401, before finally being discharged into storage compartment 101 through first heating hole 21 and second heating hole 41.
