Technical Field

The utility model relates to a medical equipment technical field especially relates to a liquid separation cooling device and have its imaging device.

Background

Nuclear medicine is an emerging discipline that employs nuclear technology to diagnose, treat, and study disease. It is a product of combining modern scientific technologies such as nuclear technology, electronic technology, computer technology, chemistry, physics, biology and the like with medicine, is also called atomic medicine, and refers to the application of nuclear radiation generated by a ray beam generated by an accelerator or a radioactive isotope in medicine. In medicine, radioisotopes and nuclear radiation may be used in diagnostic, therapeutic and medical science research; nuclear medicine imaging technology has made breakthrough progress since the 70 s due to the development of single photon emission computed tomography and positron emission computed tomography technologies and the innovation and development of radiopharmaceuticals.

Positron Emission Computed Tomography (PET) is an advanced clinical examination imaging technique in the field of nuclear medicine, and is particularly suitable for diagnosing early diseases and subclinical lesions without morphological changes and evaluating treatment effects. At present, PET especially shows important value in diagnosis and treatment of three main diseases, namely tumor, coronary heart disease and brain disease.

The PET detector is used as a core component in PET, can detect rays emitted to a receptor and generated by radioactive isotopes, converts the rays into optical signals through a scintillator, converts the optical signals into electrical signals through a photomultiplier tube, amplifies the electrical signals, and finally obtains density images of the radioactive isotopes distributed in a body, so that the shapes of organs and body tissues are reflected, and related organ functions and related physiological and biochemical information are provided. In PET, a plurality of detectors are generally arranged in an annular mode, the influence of temperature on the performance of the detectors is quite obvious, when the working temperature of the detectors is high or the temperature gradient of a plurality of detectors is overlarge, the response of the detectors is inconsistent, the signal-to-noise ratio is reduced, the imaging quality of images is influenced, and further the diagnosis result is influenced, so that the temperature of the detectors needs to be controlled.

Currently, the cooling of the detector is generally performed by air cooling, liquid cooling, or a combination of the two. For example, when the detector is water-cooled, a single annular circular pipe is usually used as a water pipe and a plurality of liquid return outlet pipes are connected in parallel. However, the annular pipeline is vertically arranged in a working state, so that the water distribution uniformity effect of the mode is poor, namely the water yield of a plurality of passages has larger difference under the condition of determined water inflow; water distributors with double-layer wall structures are also adopted, wherein a water inlet pipeline is arranged in a water return pipeline, but in the method, a temperature and flow controller needs to be arranged on each water distributor channel, the resolution problem of the flow controller needs to be particularly considered, and if the resolution is low, the flow uniformity of each channel is difficult to control; if the resolution is higher, the cost required by multiple paths is higher; and the lower the operating temperature, the higher the flow controller resolution required. The air cooling is difficult to control the temperature of the probe within a low level range at room temperature and is liable to generate noise.

Therefore, the applicability of liquid cooling (such as water and the like) controlled by the cryocooler is stronger, and the aim of controlling the working temperature of the detector can be achieved by controlling the flow passing through the detector. Considering that a plurality of detectors are often arranged on the circumference vertical to the horizontal plane in an annular mode, when fluid reaches different detectors, the influence of gravity and pipeline on-way pressure loss can be caused, so that the flow rate flowing through different detectors in the same time is different, the working temperature of the detectors is inconsistent, and the requirement of modern medicine on high-precision image quality is difficult to meet.

Referring to fig. 7 to 9, in an embodiment, the connection member 113 includes a connection pipe, the main liquid inlet pipe 111 and the auxiliary liquid inlet pipe 112 are separately disposed, and a plurality of connection pipes are disposed at intervals along an extending direction of the main liquid inlet pipe 111 and are connected to communicate the main liquid inlet pipe 111 and the auxiliary liquid inlet pipe 112, respectively. That is to say, the main liquid inlet pipe 111 and the auxiliary liquid inlet pipe 112 are designed as an integral structure, that is, the main liquid inlet pipe 111 and the auxiliary liquid inlet pipe 112 are independent tubular structures, the main liquid inlet pipe 111 encloses into a closed main liquid inlet cavity 1112, and the auxiliary liquid inlet pipe 112 encloses into a closed main liquid inlet cavity 1112.

A plurality of connecting pipes are provided at intervals in the circumferential direction of the main liquid inlet pipe 111. Each connecting pipe connects the main inlet 1112 and the sub inlet 1122. Thus, the coolant in the primary inlet chamber 1112 can enter the secondary inlet conduit 112 through the connecting tube. Because the flow rate of the cooling liquid in the main liquid inlet pipe 111 is constant, the flow is formed inside the auxiliary liquid inlet pipe 112, and the flow rate of the cooling liquid output by the second liquid inlet pipe 1121 can be controlled within a certain deviation by virtue of the connecting pipe, so that the flow rates entering the cooling pipes of the detectors are basically consistent, the working temperatures of the detectors are approximately the same, and the imaging precision of an image is further ensured.

In one embodiment, the plurality of connectors 113 are non-uniformly distributed along the extension direction of the main inlet pipe 111. That is, the interval between at least two of the connection members 113 is not equal to the interval between the remaining two connection members 113. Alternatively, the distances between the connecting members 113 may not be equal, or the distances between some connecting members 113 may be equal, and the distances between some connecting members 113 may not be equal.

Alternatively, the connection pipe may be disposed at a middle position of the two second liquid inlet pipes 1121, or may not be disposed.

In order to illustrate the effect of the arrangement form of the non-uniformly distributed connecting holes on the uniform distribution of the flow, the following simulation experiment is carried out:

the number of the connecting pieces 113 in the main liquid inlet pipe 111 and the auxiliary liquid inlet pipe 112 is determined based on the number of the second liquid inlet pipes 1121 (which is determined by the number of the probes in the imaging device) entering the probes. In this embodiment, the connection member 113 is described as an example of a connection pipe, and the layout of the connection pipe is described in a plan view of the connection pipe provided in the main liquid inlet pipe 111, as shown in fig. 11, 13, and 15.

As shown in fig. 9, the number of the second liquid inlet tubes 1121 is 34, the numbers of the 34 second liquid inlet tubes 1121 are assigned as numbers 1 to 34, meanwhile, a connecting tube is disposed between two adjacent second liquid inlet tubes 1121, and a corresponding number is assigned, but since one connecting tube is omitted in the space between two first liquid inlet tubes 1111, and meanwhile, since the number 32 of the second liquid inlet tubes 1121 fluctuates seriously, the connecting tubes corresponding to the number 32 of the second liquid inlet tubes 1121 remain. Therefore, the fluid dynamics simulation is performed by using 32 connection pipes as an initial model, the connection pipes are located between the two second liquid inlet pipes 1121, and the number of the second liquid inlet pipes 1121 is 32.

Illustratively, the number of the connecting pipes is 32, and the number of the second liquid inlet pipes 1121 is 34. The amount of liquid discharged from the liquid outlet of the 34 second liquid inlet pipes 1121 is expressed in the form of a bar graph, as shown in fig. 10, and then the fluctuation degree is calculated by the following formula.

It can be seen from the analysis of the fluctuation degree in fig. 10 that the flow rate of some of the second liquid inlet pipes 1121 is far lower than the average level, such as pipes No. 13 and No. 23, so that a connecting pipe can be additionally added near the second liquid inlet pipe 1121 to increase the flow rate at this position, taking the second liquid inlet pipe No. 13 as an example, a connecting pipe is added between the second liquid inlet pipes No. 12 and No. 13 1121, and the position of the connecting pipe between the second liquid inlet pipes No. 12 and No. 13 1121 is also the position where the fluctuation degree needs to be calculated through simulation and then a position with relatively minimum fluctuation degree is selected, such as the layout of the connecting pipes on the main liquid inlet pipe 111 shown in fig. 11, and the simulation result based on this model is shown in fig. 12.

As can be seen from the comparison between fig. 10 and fig. 12, the absolute value of the fluctuation degree of the second liquid inlet tube 1121 No. 13 is significantly decreased, that is, it is closer to the average level of 34 tube flows. Next, the second liquid inlet tube 1121 No. 23 is taken as an example. As can be seen from fig. 12, the deviation of the flow rate of the second liquid inlet tube 1121 No. 23 from the average value is the largest, so that the flow rate of the second liquid inlet tube 1121 No. 23 is increased by adding connecting tubes to 22 and 23, and the specific position is also a relatively optimal position obtained by comparing the fluctuation degrees, as shown in the layout of the connecting tubes on the main liquid inlet pipe 111 shown in fig. 13, and the simulation result obtained based on the model is shown in fig. 14.

As can be seen from comparison between fig. 14 and fig. 10, the deviation between the flow rate of the second liquid inlet tube 1121 No. 23 and the average value is reduced, and at this time, the flow rates of the other 33 second liquid inlet tubes 1121 all change, but the increase of the connection tube mainly affects the flow rate of the second liquid inlet tube 1121 near the increase position. Based on the above adjustment process, the connection pipe position of the main liquid inlet pipe 111 is shown in fig. 15, and the simulation result is shown in fig. 16.

According to the final simulation result, the fluctuation degree position is within plus or minus 3%, and a large space exists for improving the imaging performance of the detector. It should be noted that, because of the position relationship between the secondary liquid inlet pipe 112 and the primary liquid inlet pipe 111, the connection pipe is also basically corresponding to the second liquid inlet pipe 1121, and the form of adding the connection pipe omits the drawings of the second liquid inlet pipe 1121, but the position corresponding to the second liquid inlet pipe 1121 is still added.

Of course, in other embodiments of the present invention, a regulating valve is disposed in the connecting member 113, and the regulating valve is used for regulating the flow rate of the cooling liquid in the connecting member 113. The regulating valve can control the flow according to the fluctuation of the cooling liquid in the second liquid inlet pipe 1121. The flow rate of the cooling liquid in the connecting member 113 is increased or decreased by the adjusting valve, so that the flow rate of the cooling liquid entering the auxiliary liquid inlet pipe 112 from the connecting member 113 can be adjusted, and the flow rate of the cooling liquid in the second liquid inlet pipes 1121 is adjusted, so that the flow rates of the cooling liquid in the second liquid inlet pipes 1121 are substantially consistent, the temperatures of the detectors are guaranteed to be substantially consistent, and the purpose of high-quality imaging is achieved.

Referring to fig. 1 to 3 and 7 to 9, in principle, the positions of the main liquid inlet pipe 111 and the auxiliary liquid inlet pipe 112 are not limited as long as the communication relationship between the main liquid inlet chamber 1112 of the main liquid inlet pipe 111 and the auxiliary liquid inlet chamber 1122 of the auxiliary liquid inlet pipe 112 is established through the connecting member 113.
