Description

Technical Field

[0001] This utility model belongs to the field of concentration detection technology, and in particular relates to a real-time solution concentration detection device. Background Technology

[0002] In the medical field, silicone oil solution needs to be applied to the surface of needles used for injection or puncture to increase the lubrication of the needle surface and reduce damage to tissues. However, silicone oil has a high viscosity, so it usually needs to be mixed with a diluent to achieve the best lubrication effect.

[0003] The concentration of the mixture of silicone oil and diluent needs to be monitored in real time to ensure the effectiveness of the silicone oil solution coating on the surface of needle tools. Traditional detection methods usually involve inserting the probe of the detection instrument into the chamber containing the silicone oil solution. However, with prolonged use, silicone oil can easily adhere to the surface of the probe, thus affecting the accuracy of the probe in detecting the silicone oil concentration. Traditional cleaning methods usually require removing the probe, which is not very convenient. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a real-time solution concentration detection device, thereby improving the ease of cleaning the probe.

[0005] In view of this, the present invention provides a real-time solution concentration detection device, comprising:

[0006] The frame contains a mixing tank.

[0007] The detection chamber is installed inside the frame and forms a detection chamber inside it, and a circulation path is formed between the detection chamber and the mixing tank;

[0008] An online refractometer is installed on the side of the detection chamber and includes a detection probe located inside the detection chamber, used to detect the concentration of the solution inside the detection chamber in real time;

[0009] An ultrasonic cleaner is installed on the side of the testing chamber and is used to clean the surface of the testing probe.

[0010] Furthermore, the above technical solution also includes:

[0011] The front housing is installed between the detection chamber and the online refractometer, and is used for the connection between the two;

[0012] The rear housing is fitted onto the online refractometer and is detachably connected to the front housing.

[0013] In the above technical solution, further:

[0014] The detection chamber is open at one end near the front housing, and a through hole is coaxially provided on the front housing;

[0015] The detection probe is set up in a corresponding manner with the through hole.

[0016] Furthermore, the above technical solution also includes:

[0017] A sealed structure is installed between the online refractometer and the front housing;

[0018] The sealing structure includes an annular groove on the inner wall of the front housing near the online refractometer and a sealing ring installed in the annular groove.

[0019] In the above technical solution, the cyclic flow path further includes:

[0020] A circulation pump, installed inside the frame, is used to circulate the solution between the mixing tank and the detection chamber;

[0021] The mixing tank has a first outlet hole and a return hole, the detection chamber has an inlet hole and a second outlet hole, and connecting pipes are provided between the first outlet hole and the inlet hole and between the second outlet hole and the return hole.

[0022] In the above technical solution, further:

[0023] The first outlet and return holes are located on the side of the bottom of the mixing tank;

[0024] The circulating pump is installed between the second outlet hole and the return hole.

[0025] In the above technical solution, further:

[0026] The second outlet hole is located at the lower position of the detection cavity, and the inlet hole is located at the higher position of the detection cavity.

[0027] In the above technical solution, further:

[0029] In this process, a detection layer is formed between the spiral guide vane and the detection probe, and the thickness of the detection layer is greater than the required thickness of the detection layer for the detection probe.

[0030] The beneficial effects of this utility model are as follows:

[0031] 1. By setting up a detection chamber, sampling is carried out in the mixing tank and a circulation path is formed, thereby enabling real-time detection of the solution concentration in the mixing tank. This ensures the accuracy of the solution concentration in the mixing tank. Furthermore, the detection chamber facilitates the cleaning of the detection probe with an ultrasonic cleaner, avoiding the need to remove the probe when cleaning is required, thus improving the convenience of cleaning.

[0032] 2. The front and rear housings, along with the sealing structure, ensure that the detection probe is located within the detection chamber and that the system is airtight, preventing solution leakage and its impact on the surrounding environment.

This facilitates the circulation of the solution between the mixing tank and the detection chamber, preventing voids in the flowing solution and thus avoiding the generation of air bubbles, thereby ensuring detection accuracy.

[0034] 4. Furthermore, the second outlet hole is located at a low position, while the inlet hole is located at a high position, which can ensure effective and complete replacement of the solution in the detection chamber and promote its function. Attached Figure Description

[0045] The detection chamber 3 is installed inside the frame 1, and a detection chamber 4 is formed inside it, and a circulation path is formed between the detection chamber 4 and the mixing tank 2;

[0046] An online refractometer 5 is installed on the side of the detection chamber 3 and includes a detection probe 50 located inside the detection chamber 4, and is used to detect the concentration of the solution inside the detection chamber 4 in real time.

[0047] An ultrasonic cleaner 6 is installed on the side of the detection chamber 3 and is used to clean the surface of the detection probe 50.

[0048] The specific structure and model selection of the online refractometer 5 and the ultrasonic cleaner 6 are existing technologies. They are learned by those skilled in the art from the traditional online refractometer 5 and ultrasonic cleaner 6, and the models are selected accordingly. They will not be described in detail here.

[0049] As can be seen from this embodiment, by setting up the detection chamber 3, sampling is carried out in the mixing tank 2 and a circulation flow path is formed, thereby enabling real-time detection of the solution in the mixing tank 2, ensuring the accuracy of the solution concentration in the mixing tank 2. Furthermore, the detection chamber 3 facilitates the cleaning of the detection probe 50 by the ultrasonic cleaner 6, avoiding the need to remove the probe when it needs cleaning, thus improving the convenience of cleaning.

[0050] Example 2:

[0051] This embodiment provides a real-time solution concentration detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features and includes:

[0052] The front housing 7 is installed between the detection chamber 3 and the online refractometer 5, and is used for the connection between the two.

[0053] The rear housing 8 is fitted onto the online refractometer 5 and is detachably connected to the front housing 7;

[0054] The front housing 7 and the detection cavity 3 can be welded together.

[0055] As can be seen from this embodiment, the installation stability of the online refractometer 5 can be improved by setting the front housing 7 and the rear housing 8, ensuring the detection accuracy. At the same time, the detachable connection of the rear housing 8 improves the convenience of installing and disassembling the online refractometer 5, thereby improving the convenience of maintenance or repair of the online refractometer 5.

[0056] Example 3:

[0057] This embodiment provides a real-time solution concentration detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0058] The detection cavity 3 is open at one end near the front housing 7, and a through hole 9 is coaxially provided on the front housing 7;

[0059] Among them, the detection probe 50 is set correspondingly to the through hole 9;

[0060] Meanwhile, the other end of the detection chamber 3 is closed, and the connection method between it and the ultrasonic cleaner 6 is not limited in this application. Specifically, it can be connected by bolts, clips or magnetic adsorption.

[0061] As can be seen from this embodiment, by having an opening in the front housing 7 and a through hole 9 coaxially formed, it is convenient to place the detection probe 50 in the detection chamber 4, thereby ensuring the accuracy of solution concentration detection.

[0062] Example 4:

[0063] This embodiment provides a real-time solution concentration detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features and includes:

[0064] A sealed structure is installed between the online refractometer 5 and the front housing 7;

[0065] The sealing structure includes an annular groove 10 formed on the inner wall of the front housing 7 near the online refractometer 5 and a sealing ring 11 installed in the annular groove 10.

[0066] Meanwhile, the sealing ring 11 can be made of rubber.

[0067] As can be seen from this embodiment, by setting a sealing structure, the sealing performance between the online refractometer 5 and the front housing 7 can be improved after the online refractometer 5 is installed, thus avoiding leakage of solution between the online refractometer 5 and the front housing 7 due to the detection probe 50 being located inside the detection chamber 4.

[0068] Example 5:

[0069] This embodiment provides a real-time solution concentration detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a circulation path:

[0070] A circulation pump 12 is installed inside the frame 1 and is used for circulating the solution in the mixing tank 2 and the detection chamber 4.

[0071] The mixing tank 2 is provided with a first outlet hole 13 and a return hole 14, the detection chamber 4 is provided with an inlet hole 15 and a second outlet hole 16, and a connecting pipe is provided between the first outlet hole 13 and the inlet hole 15 and between the second outlet hole 16 and the return hole 14.

[0072] Meanwhile, the specific structure and model selection of the circulating pump 12 and the connecting pipe are existing mature technologies, which can be learned by those skilled in the art from traditional circulating pumps 12 and connecting pipes and the model selection can be made.

[0073] As can be seen from this embodiment, the circulation pump 12 facilitates the formation of a circulating flow, ensuring real-time replacement of the solution in the detection chamber 4, real-time detection of the concentration in the detection chamber 4, and real-time monitoring of the concentration of the solution in the mixing tank 2.

[0074] Example 6:

[0075] This embodiment provides a real-time solution concentration detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0076] The first outlet hole 13 and the return hole 14 are opened on the side of the bottom of the mixing tank 2;

[0077] The circulating pump 12 is installed between the second outlet hole 16 and the return hole 14.

[0078] As can be seen from this embodiment, the first outlet hole 13 and the return hole 14 are opened on the side of the bottom of the mixing tank 2, which facilitates the circulation of the solution between the mixing tank 2 and the detection chamber 4, reduces the possibility of air mixing into the solution in the circulation path, avoids the generation of air bubbles due to gaps in the flowing solution, and ensures detection accuracy.

[0079] Example 7:

[0080] This embodiment provides a real-time solution concentration detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0081] The second outlet hole 16 is located at the lower position of the detection cavity 3, and the inlet hole 15 is located at the higher position of the detection cavity 3.

[0082] As can be seen from this embodiment, by placing the second outlet hole 16 at a low position and the inlet hole 15 at a high position, the solution in the detection chamber 4 can be effectively and completely replaced, which promotes the effect.

[0083] Example 8:

[0084] This embodiment provides a real-time solution concentration detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0085] A spiral guide vane 17 is installed inside the detection chamber 3;

[0086] Among them, a detection layer is formed between the spiral guide plate 17 and the detection probe 50, and the thickness of the detection layer is greater than the required thickness of the detection layer of the detection probe 50.

[0087] Meanwhile, the spiral guide vane 17 and the detection cavity 3 can be welded together.

[0088] As can be seen from this embodiment, by setting the spiral guide plate 17, the effect of promoting the complete replacement of the solution in the detection chamber 4 can be further improved. Promoting the complete replacement of the solution in the detection chamber 4 can ensure that the solution to be detected at the detection probe 50 is the solution just drawn from the mixing tank 2, ensuring the real-time detection of the solution concentration in the mixing tank 2 and improving the accuracy of real-time acquisition of solution concentration.

[0089] Furthermore, the thickness of the detection layer must be greater than the actual thickness required by the detection probe 50. This can avoid affecting the accuracy of solution concentration detection due to a small detection layer thickness. Specifically, if the theoretical detection layer of the selected online refractometer 5 for the concentration detection of a specific solution (such as a mixture of silicone oil and diluent) is X, and the detection layer formed between the spiral guide plate 17 and the detection probe 50 is Y, then in terms of thickness, Y is 1.5-2 times that of X.

[0090] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
