Description

Technical Field

[0001] The present application relates to the technical field of constant temperature water baths, and in particular to a constant temperature water bath device. Background Art

[0002] The constant temperature water bath device comprises a water bath pot and a heating tube group arranged at the bottom of the water bath pot. Water is added into the water bath pot, and then the product to be heated is placed into the water; the water in the water bath device is heated by the heating tube group and the temperature is kept constant, and the heat is transferred to the test cup to be heated by heat transfer, so that the purpose of heating the reagent in the test cup can be achieved.

[0003] However, the above-mentioned constant temperature water bath device is not suitable for heating special products. Take 18F-FDG (fluorodeoxyglucose) as an example. Due to its strong radioactivity, simply wearing a lead suit cannot achieve perfect radiation isolation. In order to further enhance the safety of operation, a constant temperature water bath device that can effectively isolate radiation is specially provided. Utility Model Content

[0004] In order to enable radioactive drugs to be heated at a constant temperature while ensuring that operators can effectively isolate radiation and enhance safety, the present application provides a constant temperature water bath device.

[0005] The constant temperature water bath device provided in this application adopts the following technical solution:

[0006] A constant temperature water bath device comprises a water bath pot body and a closed cover, wherein the closed cover is composed of a mosaic plate, a lead layer and a cover body which are arranged in sequence from bottom to top.

[0007] By adopting the above technical solution: lead has a larger atomic nucleus, a large density, and a dense arrangement, and has a certain shielding effect on radioactive elements. Therefore, the setting of the lead layer can effectively isolate radiation, and because the lead layer does not directly cover the closing cover, it can effectively reduce the direct contact of water vapor with the lead layer, thereby extending the service life of the lead plate.

[0008] Preferably, the engaging plate is concavely arranged and forms a cavity with the cover body.

[0009] By adopting the above technical solution: the lead layer can be arranged in the cavity in different structural shapes and adapted to the cavity. In addition, the cavity also has a heat insulating effect, which is conducive to maintaining a constant temperature inside the water bath body.

[0010] Preferably, the lead layer is arranged in an arch shape.

[0011] By adopting the above technical solution: the arched structure is conducive to expanding the effective range of radiation isolation.

[0012] Preferably, the mosaic plate is also provided with a drainage component for reducing the accumulation of condensed water on the lead layer.

[0013] By adopting the above technical solution: when heating the radioactive sample in a constant temperature water bath, it is necessary to carry out a closed treatment, and the water bath pot needs to be covered with a closed cover. Since water vapor will contact the closed cover when the water bath pot is heated, some water will remain on the lead layer. Long-term contact will cause the lead layer to slowly oxidize and reduce the radiation protection performance. The setting of the drainage component can effectively discharge the residual water from the surface of the lead layer, thereby effectively protecting the lead plate.

[0014] Preferably, the drainage assembly includes a plurality of return holes opened on the mosaic plate and a plurality of guide grooves opened on the lead plate.

[0015] By adopting the above technical solution: high-temperature water vapor condenses into water after contacting the cold interlocking plate through the reflux hole, and returns to the water bath along the guide groove, which can reduce the residual water stagnation on the lead layer and effectively avoid the reduction of water volume in the water bath due to water evaporation.

[0016] Preferably, a heat dissipation opening is also provided on the peripheral side of the mosaic plate.

[0017] By adopting the above technical solution: lifting a corner of the closed cover, the heat dissipation openings on the peripheral side of the interlocking plate are exposed to the air, so that heat is exchanged between the inside of the water bath body and the external environment, which is conducive to rapid cooling of the water bath and effectively reduces the risk of scalding of users.

[0018] An integrally formed storage rack for carrying radioactive drugs is also arranged inside the water bath body.

[0019] By adopting the above technical solution: the setting of the one-piece storage rack is conducive to the user to place and take samples, providing convenience.

[0020] The storage rack is provided with a plurality of storage slots, and the slot surfaces of the plurality of storage slots are all provided with a lead coating.

[0021] By adopting the above technical solution: placing the sample in the storage slot, the lead coating on the slot surface of the storage slot can block radiation, further enhancing safety, and together with the sealing cover, effectively isolating the radiation of the radioactive sample to the user.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The present application fixes the arch-shaped lead layer in the cavity formed between the interlocking plate and the cover body, so that when heating a radioactive sample, it can effectively isolate radiation and protect the human body;

[0024] 2. The present application provides a drainage assembly on the embedded plate, and the lead layer is provided in the cavity formed between the embedded plate and the cover body, so that the lead layer will not be directly exposed to water, so that the lead layer can effectively avoid being corroded and oxidized by high-temperature water vapor for a long time, thereby reducing the radiation resistance performance;

[0025] 3. The present application provides heat dissipation openings on the sides of the interlocking plate, which can quickly cool down the water bath, effectively reducing the risk of users being scalded;

[0026] 4. The present application further enhances the safety performance of the water bath by providing an integrated storage rack with a storage slot inside the water bath body, and providing a lead-containing coating on the slot surface, which can effectively isolate the external radiation of the radioactive sample in the slot, thereby further enhancing the safety performance of the water bath.

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] Example 1

[0032] Example 1 of the present application discloses a constant temperature water bath device. Figure 1 and Figure 2 , including a water bath body 1 and a closed cover 2, the closed cover 2 is composed of a mosaic plate 21, a lead layer 22 and a cover body 23 fixed in sequence from bottom to top, wherein the lead layer 22 is arched and fixed in a cavity formed between the mosaic plate 21 and the cover body 23, so that the closed cover 2 has the ability to block radiation, and the arched lead layer 22 can expand the effective protection range against radiation and enhance the protection capability.

[0033] In actual use, it is only necessary to cover the closing cover 2 on the water bath body 1. Through the snap-fitting of the engaging plate 21 and the notch of the water bath body 1 and the blocking of the lead layer 22, the harmful radiation of the radioactive sample in the water bath to the human body can be cooperatively isolated. At this time, the lead coat can basically eliminate the harm of radiation.

[0034] In addition, the lead layer 22 does not directly cover the surface of the closing cover 2, but is fixed in the cavity formed between the interlocking plate 21 and the cover body 23, thereby reducing direct contact with water vapor and extending the service life of the lead plate. Figure 2 , and a drainage component 3 is also provided for reducing the condensed water stagnation remaining on the lead layer 22, two reflux holes 31 are opened on the embedded plate 21, and two guide grooves 32 are opened on the peripheral side of the lead plate close to the embedded plate 21;

[0035] The high-temperature water vapor condenses into water after contacting the cold interlocking plate 21 through the two reflux holes 31, and returns to the water bath along the four guide grooves 32. On the one hand, it can reduce the water stagnation on the lead layer 22, so that the lead layer 22 can avoid being corroded and oxidized by the high-temperature water vapor for a long time, which leads to the reduction of radiation protection performance. On the other hand, it can also reduce the risk of a sudden decrease in the amount of water in the water bath due to water evaporation.

[0036] After using the constant temperature water bath, the operator needs to take the radioactive sample out of the water bath. In order to prevent the operator from being scalded by high temperature steam, refer to Figure 2 A heat dissipation port 211 is provided around the interlocking plate 21. By simply lifting a corner of the closing cover 2 to expose the heat dissipation port 211 around the interlocking plate 21 to the air, the inside of the water bath body 1 can exchange heat with the external environment, thereby rapidly cooling the water bath.

[0037] To further facilitate the operation of users and enhance their own safety, refer to Figure 2 An integrally formed storage rack 11 is arranged inside the water bath body 1, and three storage slots 111 are provided on the storage rack 11. The inner surfaces of the storage slots 111 are provided with a lead coating 112. When a user places a radioactive sample in the storage slots 111, the lead coating 112 on the inner surfaces of the storage slots 111 can effectively isolate radiation. At the same time, by tightly covering the closing cover 2 on the water bath body 1, the radiation protection performance can be greatly enhanced, and the safety can be further enhanced.

[0038] The working process and implementation principle in Example 1 are as follows:

[0039] The operator places the radioactive sample in the storage groove 111 inside the water bath body 1, and then closes the closing cover 2 on the water bath body 1, and turns on the switch to start constant temperature water bath heating. Since the arched lead layer 22 is fixed in the closing cover 2 and the groove surface of the storage groove 111 is coated with a lead coating, harmful radiation energy can be isolated, effectively protecting the safety of the operator;

[0040] After the heating work is completed, the operator turns off the switch and lifts a corner of the closing cover 2 to expose the heat dissipation port 211 on the side of the interlocking plate 21 to the air. The inside of the water bath body 1 exchanges heat with the external environment, so that the water bath can quickly lower the temperature, which can effectively reduce the risk of operators being scalded by high-temperature steam and ensure the safety of personnel.

[0041] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
