Detailed Embodiments

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] Embodiment 1

[0021] The photosensitizer rewarming device of this embodiment, as Figure 1 shown, includes a water bath bucket 1, a heating element 2 is arranged in the water bath bucket 1, a top cover 3 for sealing the upper port of the water bath bucket 1 is arranged at the top of the water bath bucket 1, the top cover 3 is connected with a lifting mechanism 4, a vertical rotating shaft 5 is arranged at the center of the top cover 3, the upper end of the rotating shaft 5 is connected with a rotation driving mechanism 6, the lower end of the rotating shaft 5 extends into the water bath bucket 1 and is connected with a horizontal first support wire mesh plate 7, a first positioning plate 8 is arranged above the first support wire mesh plate 7, and a plurality of vertical first positioning through holes 9 are arranged on the first positioning plate 8.

[0022] The water bath bucket 1 can be a metal bucket, such as a circular stainless steel bucket, with an open upper end and a heat insulation layer arranged on the outer wall to reduce energy consumption. Water is arranged in the water bath bucket 1, and the heating element 2 is used to heat the water, and then the water is used to reposition the photosensitizer. Specifically, the heating element 2 can be an electric heating wire, which can be one or multiple, and can be linear. Preferably, it is annular or arc-shaped and is fixedly arranged on the inner side wall of the water bath bucket 1 to increase the heating area and promote uniform heating of the water.

[0023] The top cover 3 can close the upper port of the water bath bucket 1 and can be a stainless steel cover. The lifting mechanism 4 is used to drive the top cover 3 to move up and down. When the lifting mechanism 4 drives the top cover 3 to move downward to the top of the water bath bucket 1, the top cover 3 closes the water bath bucket 1. When the lifting mechanism 4 drives the top cover 3 to move upward, the water bath bucket 1 is opened. The lifting mechanism 4 can adopt existing equipment such as a cylinder or a hydraulic cylinder.

[0024] The rotating shaft 5 can be installed on the top cover 3 through a bearing. The rotation driving mechanism 6 is used to drive the rotating shaft 5 to rotate and can adopt equipment such as a reduction motor. The rotation driving mechanism 6 is fixedly installed on the upper surface of the top cover 3, and the rotation driving mechanism 6 is connected with the rotating shaft 5 through transmission parts such as a coupling and a gear set. The first support wire mesh plate 7 and the first positioning plate 8 are circular, and both the first support wire mesh plate 7 and the first positioning plate 8 are fixed on the rotating shaft 5. The first support wire mesh plate 7 is used to support the photosensitizer packaged in a glass bottle, and the first positioning through holes 9 on the first positioning plate 8 are used to position the photosensitizer. One bottle of photosensitizer is placed in each first positioning through hole 9. A plurality of mesh holes are arranged on the first support wire mesh plate 7, and the aperture of the mesh holes is smaller than the outer diameter of the photosensitizer packaging bottle. When the first support wire mesh plate 7 is immersed in water, the water can penetrate the first support wire mesh plate 7. The aperture of the first positioning through hole 9 is slightly larger than the outer diameter of the photosensitizer packaging bottle to ensure that the photosensitizer can be easily placed into the first positioning through hole 9.

[0025] When using the present utility model to rewarm the photosensitizer, an appropriate amount of clear water is added to the water bath bucket 1. First, the water is heated to a suitable temperature by the heating element 2, and then the lifting mechanism 4 drives the top cover 3, the rotating shaft 5, the first support wire mesh disk 7, the first positioning disk 8 and other components to move upward as a whole, so that the first support wire mesh disk 7 and the first positioning disk 8 move above the water level. Then, the photosensitizers to be rewarmed are individually placed into each first positioning through hole 9. Next, the lifting mechanism 4 drives the top cover 3, the rotating shaft 5, the first support wire mesh disk 7, the first positioning disk 8, the photosensitizer, etc. to move downward as a whole until the top cover 3 closes the water bath bucket 1. At this time, the first support wire mesh disk 7, the first positioning disk 8 and the photosensitizer are immersed in the water. The rotation driving mechanism 6 drives the rotating shaft 5 to rotate slowly at a constant speed. The rotating shaft 5 drives the first support wire mesh disk 7, the first positioning disk 8 and the photosensitizer to rotate, promoting the water flow and making the water temperature of each part consistent, so as to uniformly heat each bottle of photosensitizer.

[0026] After the rewarming is completed, the lifting mechanism 4 drives the top cover 3, the rotating shaft 5, the first support wire mesh disk 7, the first positioning disk 8, the photosensitizer and other components to move upward as a whole above the water surface again, and then the photosensitizer can be taken out.

[0027] In order to accurately control the water temperature in the water bath bucket 1, a temperature sensor 10 is arranged in the water bath bucket 1, and the temperature sensor 10 can adopt the existing technology.

[0028] In order to ensure that the top cover 3 can be lifted and lowered stably, a support 16 is arranged above the water bath bucket 1. A vertical guide post 17 is arranged on the support 16. The guide post 17 penetrates through the top cover 3 and is slidably matched with the top cover 3. The lifting mechanism 4 is installed on the support 16. The support 16 can be a portal support, including two vertical columns and a horizontal cross beam. The two columns are arranged on both sides of the water bath bucket 1, and the guide post 17 and the lifting mechanism 4 are installed on the cross beam. The support 16 can also be an inverted L-shaped support, including a column and a cantilever fixed at the top of the column. The guide post 17 and the lifting mechanism 4 are installed on the cantilever. A positioning ear extending outside the water bath bucket 1 is arranged at the edge of the top cover 3, and the guide post 17 penetrates through the positioning ear and is slidably matched with the positioning ear.

[0029] In order to improve the sealing performance between the top cover 3 and the water bath bucket 1, a sealing gasket 20 is arranged between the top cover 3 and the water bath bucket 1, and the sealing gasket 20 can be a rubber gasket, etc.

[0030] Embodiment Two

[0031] In Embodiment One, the number of the first positioning through holes 9 can be several, more than a dozen or more, but the number is limited. When the number of photosensitizers to be rewarmed in a certain batch is greater than the number of the first positioning through holes 9, two rewarming operations are required, and the total rewarming time is relatively long, affecting the rewarming efficiency.

[0032] In this embodiment, on the basis of the first embodiment, a second support wire mesh plate 12 and a second positioning plate 13 are added. Specifically, as Figure 2 shown, in this embodiment, a detachable connecting column 11 is provided at the lower end of the rotating shaft 5. The connecting column 11 is coaxial with the rotating shaft 5, and a horizontal second support wire mesh plate 12 is provided on the connecting column 11. A second positioning plate 13 is provided above the second support wire mesh plate 12, and a plurality of vertical second positioning through holes 14 are provided on the second positioning plate 13. The second support wire mesh plate 12 and the second positioning plate 13 are fixed on the connecting column 11, and the structure of the second support wire mesh plate 12 is the same as that of the first support wire mesh plate 7, and the structure of the second positioning plate 13 is the same as that of the first positioning plate 8. The second support wire mesh plate 12 and the second positioning plate 13 cooperate to be able to carry a number of photosensitizers.

[0033] When the number of photosensitizers to be rewarmed is less than the number of the first positioning through holes 9, the connecting column 11 does not need to be provided; when the number of photosensitizers to be rewarmed is greater than the number of the first positioning through holes 9, the connecting column 11 can be installed at the lower end of the rotating shaft 5, and then the photosensitizers are placed into the first positioning through holes 9 and the second positioning through holes 14, and then the photosensitizers in the first positioning through holes 9 and the second positioning through holes 14 are rewarmed simultaneously.

[0034] It can be seen that this embodiment can rewarm a larger number of photosensitizers without the need for multiple rewarming, and can improve the efficiency when mass-rewarming photosensitizers.

[0035] In order to facilitate the disassembly and installation of the connecting column 11, a connecting screw rod 15 is provided at the upper end of the connecting column 11. An external thread is provided on the outer wall of the connecting screw rod 15, and a threaded hole is provided on the lower end surface of the rotating shaft 5. The connecting screw rod 15 is in threaded connection with the threaded hole, and the disassembly and assembly are convenient.

[0036] The glass bottles for packaging photosensitizers are fragile. In order to protect the glass bottles, in the present utility model, the first support wire mesh plate 7 and the second support wire mesh plate 12 are wire meshes. A mesh-shaped elastic pad 18 is provided on the upper surface of the first support wire mesh plate 7 and the second support wire mesh plate 12. The elastic pad 18 can be made of a rubber pad. Elastic protective sleeves 19 are provided on the inner walls of the first positioning through holes 9 and the second positioning through holes 14. The protective sleeves 19 can also be made of rubber sleeves. The inner diameter of the protective sleeve 19 is slightly larger than the outer diameter of the photosensitizer packaging bottle. Both the elastic pad 18 and the protective sleeve 19 have elasticity, and can effectively shock-absorb the photosensitizer packaging bottle, prevent the packaging bottle from being damaged, and improve the safety of the photosensitizer.

[0037] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
