Endotoxin has high biological activity, and even trace existence can produce serious toxic reaction to human body, such as fever, inflammation, and even shock. Therefore, in the fields of medicine, food and medical devices, accurate detection of endotoxin has important significance. The key link of endotoxin detection lies in sampling and analysis, and the detection head as the core component of the analyzer directly affects the sensitivity, stability and convenience of detection. Efficient and convenient endotoxin analyzer detection head can greatly improve the detection efficiency and accuracy, and meet the demand of related industries for rapid detection of endotoxin.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figs. 1-3 This utility model provides an embodiment of a portable endotoxin analyzer detection head, including a detection rod 1, a detection probe 2 at the bottom of the detection rod 1, the detection rod 1 and the detection probe 2 being connected by a quick-connect mechanism, and a convenient mechanism being provided on the outside of the detection rod 1; the quick-connect mechanism includes a connecting sleeve 3, the connecting sleeve 3 being fixedly connected to the outside of the detection rod 1, a sliding sleeve 4 being slidably connected to the outer wall of the connecting sleeve 3, a spring 5 being sleeved on the outside of the connecting sleeve 3, a limiting bead 6 being provided inside the connecting sleeve 3, a limiting ring 7 being fixedly connected to the side wall of the detection probe 2, a limiting ring 8 being fixedly connected to the outside of the detection probe 2, the detection probe 2 being slidably connected inside the connecting sleeve 3, the bottom of the detection rod 1 being in contact with the top of the detection probe 2, one end of the spring 5 being fixedly connected to the side wall of the connecting sleeve 3, the other end of the spring 5 being fixedly connected to the side wall of the sliding sleeve 4, the limiting bead 6 being slidably connected between the limiting ring 7 and the limiting ring 8, a limiting block 9 being fixedly connected to the side wall of the limiting ring 8, a limiting groove 10 being opened inside the connecting sleeve 3, and the limiting block 9 being slidably connected inside the limiting groove 10;
[0030] When it is necessary to connect the detection rod 1 and the detection probe 2, firstly, push the sliding sleeve 4 upward to apply pressure to the spring 5. After the spring 5 is compressed, the space for the limiting bead 6 is exposed, preparing for installation. Next, insert the detection probe 2 into the connecting sleeve 3, so that the limiting block 9 on the outside of the detection probe 2 enters the limiting groove 10 of the connecting sleeve 3. At the same time, the top of the detection probe 2 is in contact with the sensing element at the bottom of the detection rod 1. After insertion, release the sliding sleeve 4. At this time, the spring 5 returns to its original position, pushing the sliding sleeve 4 downward so that the inner ring of the sliding sleeve 4 covers the outside of the limiting bead 6, restricting the limiting bead 6 and forming a locked state. Thus, the installation of the detection probe 2 is completed. Through the above operation, the effect of quickly connecting the detection head is achieved, and the connection stability and normal operation of the equipment are ensured.
[0031] Reference Figs. 1-3 The convenient mechanism includes a housing 11, which is fixedly connected to the outside of the detection rod 1. A protective sleeve 16 is slidably connected to the side wall of the detection probe 2. The housing 11 is a regular octagonal design, and each side is provided with an anti-slip pad 12. A connecting ring 15 is fixedly connected to the bottom of the protective sleeve 16. A connecting rope 14 is fixedly connected to the side wall of the connecting ring 15. A fixing ring 13 is fixedly connected to one end of the connecting rope 14. The side wall of the fixing ring 13 is fixedly connected to the side wall of the housing 11.
[0032] When using the equipment for testing, the user can easily control the device by holding the outer casing 11. The anti-slip pads 12 on the outside of the outer casing 11 further enhance the anti-slip properties of the device, ensuring operational stability. Especially in humid or long-term operating environments, it can effectively prevent the device from slipping, improving the safety of the test. The sides of the outer casing 11 ensure that the fingers of the tester are always in a flat position, regardless of how the tester holds the test rod 1, reducing the pressure that needs to be applied to the hand, effectively reducing fatigue during long-term operation, and improving work efficiency and comfort. When the device is not in use, the user can bend the connecting rope 14 to deform it and put the connecting ring 15 on the outside of the test probe 2, thereby effectively protecting the test probe 2 from external impacts and contamination, and extending the service life of the device.
[0033] Working principle: When it is necessary to connect the detection rod 1 and the detection probe 2, first push the sliding sleeve 4 upward to compress the spring 5, exposing the movement space of the limiting bead 6. Then insert the detection probe 2 into the inside of the connecting sleeve 3, so that the limiting block 9 connected to it is inserted into the inside of the limiting groove 10, and the top of the detection probe 2 is in contact with the bottom sensing element of the detection rod 1. Then release the sliding sleeve 4. At this time, the spring 5 will return to its original position due to the loss of pressure, and push the sliding sleeve 4 downward to make the inner ring of the sliding sleeve 4 cover the outside of the limiting bead 6 again, thus restricting the limiting bead 6. The installation of the detection probe 2 is thus completed.
[0034] When using the equipment for testing, the outer casing 11 can be held by hand. The anti-slip pad 12 on the outside of the outer casing 11 improves the anti-slip properties of the equipment. The side of the outer casing 11 ensures that the fingers of the tester are always on a flat surface no matter how the tester holds the test rod 1, reducing the pressure required on the hand. When the equipment is not needed for work, the connecting rope 14 can be bent to deform it, and the connecting ring 15 can be placed on the outside of the test probe 2 for protection.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
